图3是本公开实施例提供的一种模块壳体的结构示意图。如图3所示，该模块壳体10包括可拆卸相连的上壳体11和下壳体12。上壳体11与下壳体12可以通过螺钉连接，也可以相互卡接，或者也可以采用粘接的方式进行连接。在一些示例中，模块壳体10还可以是一体结构，即上壳体11和下壳体12为相连的一个整体结构。FIG. 3 is a schematic structural diagram of a module housing provided by an embodiment of the present disclosure. As shown in FIG. 3 , themodule housing 10 includes anupper housing 11 and alower housing 12 that are detachably connected. Theupper casing 11 and thelower casing 12 can be connected by screws, or can be clamped to each other, or can also be connected by means of bonding. In some examples, themodule housing 10 may also be an integral structure, that is, theupper housing 11 and thelower housing 12 are connected as an integral structure.

插头开口10a位于上壳体11上，接线开口10b位于下壳体12上，具体可以位于下壳体12的侧壁上。The plug opening 10 a is located on theupper casing 11 , and thewiring opening 10 b is located on thelower casing 12 , specifically, on the side wall of thelower casing 12 .

插头开口10a的数量可以根据插头20的数量进行设置，作为示例，本公开实施例的取电插头40包括3个插头20，上壳体11具有3个插头开口10a。The number of theplug openings 10a may be set according to the number of theplugs 20. As an example, thepower taking plug 40 of the embodiment of the present disclosure includes threeplugs 20, and theupper housing 11 has threeplug openings 10a.

其中，插接头的插头20的数量和母线槽的插接槽的数量相关，例如，母线槽包括三个插接槽，那么，插接头包括三个插头20，每个插头20插入至一个插接槽111中。The number ofplugs 20 of the plug connector is related to the number of plug grooves of the busbar.

Theplug 20 protrudes from one end of the right prism, and themodule housing 10 is set in a right prism shape, which facilitates the storage and assembly of thepower plug 40 and facilitates modularization.

如图3所示，模块壳体10的外侧壁具有卡扣101，卡扣101与箱体30卡接。As shown in FIG. 3 , the outer side wall of themodule housing 10 has abuckle 101 , and thebuckle 101 is clipped with thebox body 30 .

卡扣101可以分布在下壳体12的多个侧壁上，在下壳体12不同侧壁上分布的卡扣101数量可以相同也可以不同。将取电插头40连接到插接箱时，可以直接将下壳体12放入插接箱上相应的装配位置，利用卡扣101与插接箱卡接。卡扣101连接方便，便于插接箱的模块化。Thebuckles 101 may be distributed on a plurality of side walls of thelower casing 12 , and the number of thebuckles 101 distributed on different side walls of thelower casing 12 may be the same or different. When the power-takingplug 40 is connected to the plug-in box, thelower shell 12 can be directly put into the corresponding assembly position on the plug-in box, and theclips 101 are used for clamping with the plug-in box. Thebuckle 101 is convenient to connect, which facilitates the modularization of the plug-in box.

图4是本公开实施例提供的一种取电插头与箱体的装配示意图。如图4所示，模块壳体10的至少一个侧壁具有防呆凸棱102，箱体30具有防呆缺口30b，防呆缺口30b位于模块安装口30a的边缘，防呆凸棱102位于防呆缺口30b中。FIG. 4 is a schematic diagram of the assembly of a power-taking plug and a box body provided by an embodiment of the present disclosure. As shown in FIG. 4 , at least one side wall of themodule housing 10 has afoolproof rib 102, thebox body 30 has afoolproof notch 30b, thefoolproof notch 30b is located at the edge of themodule installation port 30a, and thefoolproof ridge 102 is located at the stay in thegap 30b.

在将取电插头40往模块安装口30a安装时，防呆凸棱102对准防呆缺口30b，取电插头40才能够顺利安装到位。通过防呆凸棱102和防呆缺口30b的配合，能防止安装取电插头40时，将取电插头40装反。防呆凸棱102与防呆缺口30b的配合，还能够起到导向的作用，避免取电插头40在安装时倾斜。When the power-takingplug 40 is installed to themodule installation port 30a, the fool-proofing protruding rib 102 is aligned with the fool-proofing notch 30b, so that the power-takingplug 40 can be smoothly installed in place. Through the cooperation of the fool-proofconvex rib 102 and the fool-proof notch 30b, it can be prevented that when the power-takingplug 40 is installed, the power-takingplug 40 is installed in reverse. The cooperation between the fool-proof ridges 102 and the fool-proof notch 30b can also play a guiding role, so as to prevent the power-takingplug 40 from tilting during installation.

In other examples, one or more foolproof protrudingribs 102 may be provided on each of a plurality of side walls of themodule housing 10 , for example, two opposite side walls or two adjacent side walls. One or morefoolproof notches 30b are correspondingly provided on thebox body 30 . For example, when two opposite side walls of themodule housing 10 are provided with fool-proof ridges 102, the fool-proof ridges 102 on the two side walls are not symmetrical, and the symmetry here refers to center symmetry. The fool-proof ridges 102 on the two side walls are asymmetrical, that is to say, when the fool-proof ridges 102 of the power-takingplug 40 are aligned with the fool-proof notch 30b, after the power-takingplug 40 is rotated 180°, the side Thefoolproof ridges 102 on the wall and thefoolproof notch 30b on thebox body 30 are not aligned with each other. For another example, when the fool-proof ridges 102 are provided on the two adjacent side walls of themodule housing 10, the fool-proof ridges 102 on the two side walls are asymmetrical, and the symmetry here refers to rotational symmetry. The fool-proof ridges on the two side walls are asymmetrical, that is, when the fool-proof ridges 102 of the power-takingplug 40 are aligned with the fool-proof notch 30b, the power-takingplug 40 is rotated by a certain angle, for example, 90° , the fool-proof ridges 102 on the side walls and the fool-proof notch 30b on thebox body 30 are not aligned with each other.

图5是本公开实施例提供的另一种取电插头与箱体的装配示意图。如图5所示，作为另一种可能的实现方式中，该示例中，模块壳体10的至少一个侧壁具有第一防呆槽103，箱体30具有防呆凸棱102，防呆凸棱102位于模块安装口30a的边缘，防呆凸棱102位于第一防呆槽103中。FIG. 5 is a schematic diagram of the assembly of another power-taking plug and a box provided by an embodiment of the present disclosure. As shown in FIG. 5 , as another possible implementation manner, in this example, at least one side wall of themodule housing 10 has a first fool-proof groove 103 , and thebox body 30 has a fool-proofconvex rib 102 . Therib 102 is located at the edge of the module installation opening 30 a, and the fool-proofconvex rib 102 is located in the first fool-proof groove 103 .

该示例对比于图4所示的示例，相当于是交换了防呆凸棱102的位置，将防呆凸棱102设置在了箱体30上。在将取电插头40安装到模块安装口30a时，将第一防呆槽103的端部对准防呆凸棱102，使防呆凸棱102滑入第一防呆槽103中。Compared with the example shown in FIG. 4 , this example is equivalent to exchanging the positions of the fool-proof ridges 102 , and disposing the fool-proof ridges 102 on thebox body 30 . When installing thepower taking plug 40 into themodule installation port 30 a , the end of the firstfoolproof groove 103 is aligned with thefoolproof ridge 102 , so that thefoolproof ridge 102 slides into the firstfoolproof groove 103 .

图6是本公开实施例提供的一种取电插头的结构示意图。如图6所示，模块壳体10还具有两个第二防呆槽11a。第二防呆槽11a和插头开口10a位于模块壳体10的同一表面，两个第二防呆槽11a位于插头开口10a相反的两侧。两个第二防呆槽11a到距离各自最近的插头20的插接部的距离不同，插头20的插接部是指插头20相对模块壳体10伸出的部分。FIG. 6 is a schematic structural diagram of a power-taking plug provided by an embodiment of the present disclosure. As shown in FIG. 6 , themodule housing 10 also has two secondfoolproof grooves 11a. The secondfoolproof grooves 11a and theplug opening 10a are located on the same surface of themodule housing 10, and the two secondfoolproof grooves 11a are located on opposite sides of theplug opening 10a. The distances from the two secondfoolproof grooves 11a to the insertion portion of theplug 20 closest to each other are different.

本公开实施例中，插头开口10a位于上壳体11，第二防呆槽11a也位于上壳体11。在将取电插头40插接到母线槽时，第二防呆槽11a能够在取电插头40接反时，无法顺利插接到位。在母线槽上具有与第二防呆槽11a配合的凸起，取电插头40顺利接入母线槽时，母线槽上的凸起正好卡入到两个第二防呆槽11a中。母线槽上的凸起可以是与第二防呆槽11a间隙配合的凸棱。In the embodiment of the present disclosure, the plug opening 10 a is located in theupper casing 11 , and the secondfoolproof groove 11 a is also located in theupper casing 11 . When the power-takingplug 40 is inserted into the busbar slot, the secondfoolproof slot 11a can not be smoothly inserted into position when the power-takingplug 40 is reversely connected. There are protrusions on the busbar that cooperate with the secondfoolproof grooves 11a. When thepower plug 40 is smoothly connected to the busbar, the protrusions on the busbar just snap into the two secondfoolproof grooves 11a. The protrusion on the busbar can be a rib that is clearance fit with the secondfoolproof groove 11a.

由于插头开口10a位于两个第二防呆槽11a之间，而两个第二防呆槽11a到距离各自最近的插头20的插接部的距离是不同的，因此在取电插头40不小心接反时，多个插头20能够插到母线槽中，但是第二防呆槽11a无法与母线槽上的凸起相对，导致凸起无法卡入第二防呆槽11a中，这就使得取电插头40无法插接到位，以避免电路接错引发危险。Since theplug opening 10a is located between the two secondfoolproof grooves 11a, and the distances from the two secondfoolproof grooves 11a to the insertion portion of theplug 20 closest to therespective plugs 20 are different, theplug 40 is not careful when taking the power When the connection is reversed, a plurality ofplugs 20 can be inserted into the busbar groove, but the secondfoolproof groove 11a cannot be opposite to the protrusion on the busbar groove, so that the protrusion cannot be stuck into the secondfoolproof groove 11a, which makes the removal Theelectrical plug 40 cannot be plugged into place to avoid danger caused by wrong circuit connection.

可选地，两个第二防呆槽11a的深度和/或宽度不同。Optionally, the depth and/or width of the two secondfoolproof grooves 11a are different.

在一些示例中，两个第二防呆槽11a的宽度可以不同。与两个第二防呆槽11a配合的凸起的宽度也不同，这样在将取电插头40插接到母线槽中时，取电插头40不小心接反，由于第二防呆槽11a的宽度与凸起的宽度不匹配，因此取电插头40无法插接到位，也能避免电路接错引发危险。In some examples, the widths of the two secondfoolproof grooves 11a may be different. The widths of the protrusions matched with the two secondfoolproof grooves 11a are also different, so that when thepower plug 40 is inserted into the busway, thepower plug 40 is accidentally connected in reverse, because the secondfoolproof groove 11a has a different width. The width does not match the width of the protrusion, so thepower plug 40 cannot be inserted in place, and the danger caused by wrong circuit connection can also be avoided.

在一些示例中，两个第二防呆槽11a的深度可以不同。与两个第二防呆槽11a配合的凸起的高度也不同，这样在将取电插头40插接到母线槽中时，取电插头40不小心接反，由于第二防呆槽11a的深度与凸起的深度不匹配，因此取电插头40无法插接到位，也能避免电路接错引发危险。In some examples, the depths of the two secondfoolproof grooves 11a may be different. The heights of the protrusions matched with the two secondfoolproof slots 11a are also different, so that when thepower taking plug 40 is inserted into the bus bar slot, thepower taking plug 40 is accidentally connected in reverse, due to the The depth does not match the depth of the protrusion, so thepower plug 40 cannot be inserted in place, and the danger caused by wrong circuit connection can also be avoided.

在另一些示例中，两个第二防呆槽11a的深度和宽度也可以都不同，也能够避免电路接错引发危险。In other examples, the depth and width of the two second fool-proof grooves 11a may also be different, which can also avoid danger caused by wrong circuit connection.

图7是本公开实施例提供的一种插头的分解结构示意图。图8是本公开实施例提供的一种插头的组装结构示意图。如图7和图8所示，插头20包括绝缘板21和取电插片22。FIG. 7 is a schematic diagram of an exploded structure of a plug provided by an embodiment of the present disclosure. FIG. 8 is a schematic diagram of an assembly structure of a plug provided by an embodiment of the present disclosure. As shown in FIG. 7 and FIG. 8 , theplug 20 includes an insulatingplate 21 and a power-takingblade 22 .

取电插头40的多个插头20中，至少一个插头20包括两个取电插片22，两个取电插片22位于绝缘板21相反的两侧，两个取电插片22相互绝缘。例如，图2中，取电插头40包括3个插头20，其中包括两个第一插头2001和一个第二插头2002。Among the plurality ofplugs 20 of thepower taking plug 40, at least oneplug 20 includes twopower taking blades 22 located on opposite sides of the insulatingplate 21, and the twopower taking blades 22 are insulated from each other. For example, in FIG. 2 , the power-takingplug 40 includes threeplugs 20 , including twofirst plugs 2001 and onesecond plug 2002 .

本公开实施例中，第一插头2001包括绝缘板21和两个取电插片22，两个取电插片22位于绝缘板21相反的两面，且相互绝缘，两个取电插片22对应不同的极性。In the embodiment of the present disclosure, thefirst plug 2001 includes an insulatingplate 21 and two power-taking inserts 22. The two power-takinginserts 22 are located on opposite sides of the insulatingplate 21 and are insulated from each other, and the two power-takinginserts 22 correspond to each other. different polarities.

两个取电插片22对应不同的极性，是指，在输入直流电时，两个取电插片22分别与正极和负极相连，在输入交流电时，两个取电插片22分别与不同的相线相连，或是分别与相线和零线相连。The two power-takinginserts 22 correspond to different polarities, which means that when direct current is input, the two power-takinginserts 22 are respectively connected with the positive and negative poles, and when alternating current is input, the two power-takinginserts 22 are respectively connected with different polarities. connected to the phase line, or to the phase line and the neutral line respectively.

在取电插头40进行取电时，两个取电插片22与母线槽的一个插接槽中的两个导电板分别接触。同一个插接槽中，在母线槽供给直流电时，两个导电板分别连接正极和负极，在母线槽供给交流电时，两个导电板分别连接不同的相线或是相线与零线。When the power-takingplug 40 is taking power, the two power-takinginserts 22 are in contact with the two conductive plates in one of the insertion slots of the bus bar, respectively. In the same socket, when the busbar supplies direct current, the two conductive plates are respectively connected to the positive and negative electrodes, and when the busbar supplies alternating current, the two conductive plates are respectively connected to different phase lines or phase and neutral lines.

由于两个取电插片22分别布置在绝缘板21相反的两面，并且两个取电插片22相互绝缘，因此在取电插头40与母线槽进行连接时，通过一个第一插头2001就能够实现两极的连接，从而能减少插头的数量，使取电插头40能设置的更小。Since the two power-takinginserts 22 are respectively arranged on opposite sides of the insulatingplate 21, and the two power-takinginserts 22 are insulated from each other, when the power-takingplug 40 is connected to the bus duct, afirst plug 2001 can be used to The connection of two poles is realized, so that the number of plugs can be reduced, so that the power-takingplug 40 can be set smaller.

第二插头2002包括绝缘板21和一个取电插片22，一个取电插片22位于绝缘板21的一侧。Thesecond plug 2002 includes an insulatingplate 21 and a power-takinginsert 22 , and a power-takinginsert 22 is located on one side of the insulatingplate 21 .

第二插头2002可以用于接地，在取电插头40连接至母线槽时，第二插头2002通过一个取电插片22与母线槽中接地的导电板接触，从而将插接箱接地。Thesecond plug 2002 can be used for grounding. When the power-takingplug 40 is connected to the busbar, thesecond plug 2002 contacts the grounded conductive plate in the busbar through a power-takingblade 22, thereby grounding the plug box.

如图7所示，绝缘板21包括插接段211和接线固定段212。插接段211位于模块壳体10外，接线固定段212位于模块壳体10内，接线固定段212与模块壳体10相连。As shown in FIG. 7 , the insulatingplate 21 includes a plug-insegment 211 and awiring fixing segment 212 . The plug-insegment 211 is located outside themodule housing 10 , thewiring fixing segment 212 is located inside themodule housing 10 , and thewiring fixing segment 212 is connected to themodule housing 10 .

可选地，接线固定段212的两侧可以连接有连接部2121，连接部2121用于与模块壳体10相连。例如连接部2121具有连接孔，连接部2121通过螺钉与上壳体11相连。Optionally, two sides of thewiring fixing section 212 may be connected with connectingparts 2121 , and the connectingparts 2121 are used for connecting with themodule housing 10 . For example, the connectingportion 2121 has a connecting hole, and the connectingportion 2121 is connected to theupper casing 11 by screws.

取电插片22包括取电段221和接线段222。取电段221位于模块壳体10外，且位于插接段211的一侧。接线段222位于模块壳体10内，且位于接线固定段212的一侧，接线段222与接线固定段212相连。The power-takinginsert 22 includes a power-takingsection 221 and awiring section 222 . Thepower taking section 221 is located outside themodule housing 10 and on one side of the plug-insection 211 . Thewiring segment 222 is located in themodule housing 10 and is located on one side of thewiring fixing segment 212 , and thewiring segment 222 is connected to thewiring fixing segment 212 .

取电插片22的接线段222与绝缘板21连接，插接段211用于取电插头40与母线槽连接时与母线槽中的导电板接触。接线段222在模块壳体10内，以与由接线开口10b引入的导线进行连接。Thewiring section 222 of the power-takinginsert 22 is connected to the insulatingplate 21, and the plug-insection 211 is used for contacting the conductive plate in the bus-bar slot when the power-takingplug 40 is connected to the bus-bar slot. Thewiring section 222 is inside themodule housing 10 to connect with the wires introduced through thewiring opening 10b.

如图7所示，取电段221具有向远离绝缘板21凸起的接电部2211，接电部2211具有第二接电面2211a。As shown in FIG. 7 , thepower taking section 221 has apower connection portion 2211 protruding away from the insulatingplate 21 , and thepower connection portion 2211 has a secondpower connection surface 2211 a.

取电插头40插入至母线槽中时，接电部2211能够在形变作用下，使第二接电面2211a与导电板紧密接触，而实现导通良好。When the power-takingplug 40 is inserted into the busbar slot, the power-connectingportion 2211 can make the second power-connectingsurface 2211a closely contact with the conductive plate under the action of deformation, so as to achieve good conduction.

即使取电插片22在长时间使用下，导致形变效果变差，但是插头20还有绝缘板21的支撑，在绝缘板21的支撑下，取电插片22依然能够和导电板保持良好导通状态。Even if the power-takinginsert 22 is used for a long time, the deformation effect becomes poor, but theplug 20 is also supported by the insulatingplate 21. Under the support of the insulatingplate 21, the power-takinginsert 22 can still maintain good conduction with the conductive plate. pass status.

如图7所示，取电段221包括多个导电弹片2212，多个导电弹片2212相互独立，互相间隔排布，呈梳齿状，每个导电弹片2212均具有接电部2211。As shown in FIG. 7 , thepower taking section 221 includes a plurality of conductiveelastic pieces 2212 , which are independent of each other and are arranged at intervals in a comb-like shape. Each conductiveelastic piece 2212 has apower connection portion 2211 .

图9是本公开实施例提供的一种导电弹片的结构示意图。如图9所示，导电弹片2212的接电部2211可以包括依次相连的第一斜片a1、平片a2和第二斜片a3，第一斜片a1靠近取电插头40的底部，第二斜片a3远离取电插头40的底部，取电插头40的底部也即是靠近上壳体11的位置。FIG. 9 is a schematic structural diagram of a conductive elastic sheet provided by an embodiment of the present disclosure. As shown in FIG. 9 , thepower connection portion 2211 of the conductiveelastic sheet 2212 may include a first inclined sheet a1, a flat sheet a2 and a second inclined sheet a3 connected in sequence, the first inclined sheet a1 The oblique piece a3 is far away from the bottom of the power-takingplug 40 , and the bottom of the power-takingplug 40 is also a position close to theupper casing 11 .

第一斜片a1、平片a2和第二斜片a3形成前述的接电部2211，平片a2远离绝缘板21的表面形成第二接电面2211a。The first inclined sheet a1, the flat sheet a2 and the second inclined sheet a3 form the aforementionedelectrical connection portion 2211, and the surface of the flat sheet a2 away from the insulatingplate 21 forms the secondelectrical connection surface 2211a.

这样，取电插头40插入至母线槽时，每个导电弹片2212的接电部2211被挤压，使得第一斜片a1和第二斜面a2发生展平趋势的形变，促使平片a2的外端面和母线槽中的导电板紧密贴合，也即是，第二接电面2211a与导电板紧密贴合，进而实现导通良好。In this way, when thepower taking plug 40 is inserted into the busbar slot, thepower connection portion 2211 of each conductiveelastic sheet 2212 is squeezed, so that the first inclined sheet a1 and the second inclined plane a2 are deformed in a flattening trend, and the outer surface of the flat sheet a2 is urged. The end face is closely attached to the conductive plate in the busway, that is, the secondelectrical connection surface 2211a is closely attached to the conductive plate, thereby achieving good conduction.

取电插片22包括多个导电弹片2212，那么，可以通过控制导电弹片2212的数量，来适配所传输的电流的大小，例如，如果取电插头40所传输的电流比较大，那么可以通过增多导电弹片2212的数量，来增大第二接电面2211a的总面积，以使大电流通过。The power-takingplug 22 includes a plurality of conductiveelastic pieces 2212. Then, the size of the transmitted current can be adapted by controlling the number of the conductiveelastic pieces 2212. For example, if the current transmitted by the power-takingplug 40 is relatively large, it can be passed through The number of the conductiveelastic pieces 2212 is increased to increase the total area of the secondelectrical connection surface 2211a so as to allow a large current to pass.

取电插片22包括多个导电弹片2212，这些导电弹片2212相互独立，那么，即使某个或者某些导电弹片2212因形变而与母线槽的导电板接触不良，但是不会影响到其他导电弹片2212，使取电插头40和母线槽的导电板依然保持导通的状态。The power-takinginsert 22 includes a plurality of conductiveelastic pieces 2212, and these conductiveelastic pieces 2212 are independent of each other, so even if one or some of the conductiveelastic pieces 2212 are in poor contact with the conductive plates of the busbar due to deformation, other conductive elastic pieces will not be affected. 2212, so that the power-takingplug 40 and the conductive plate of the bus bar are still in a conductive state.

在取电插片22呈一体成型的片状结构时，即多个导电弹片2212连成一个整体，那么，取电插片22的接电部2211也可以包括上述的第一斜片a1、平片a2和第二斜片a3。When the power-takinginsert 22 has an integrally formed sheet-like structure, that is, the plurality of conductiveelastic pieces 2212 are connected as a whole, then the power-connectingportion 2211 of the power-takinginsert 22 may also include the above-mentioned first inclined piece a1, flat sheet a2 and second oblique sheet a3.

示例性地，取电插片22可以为冲压结构件，通过冲压的形式直接形成多个导电弹片2212。Exemplarily, the power-takinginsert 22 may be a stamped structural member, and a plurality of conductiveelastic pieces 2212 are directly formed in the form of stamping.

如图6所示，绝缘板21位于模块壳体10外的部分呈箭头状。图10是本公开实施例提供的一种绝缘板的结构示意图。如图10所示，插接段211包括相连的竖直板2111和箭头部2112。As shown in FIG. 6 , the portion of the insulatingplate 21 located outside themodule case 10 is in the shape of an arrow. FIG. 10 is a schematic structural diagram of an insulating plate provided by an embodiment of the present disclosure. As shown in FIG. 10 , the plug-insegment 211 includes a connectedvertical plate 2111 and anarrow portion 2112 .

图11是图6的局部放大示意图。如图11所示，取电插片22的靠近箭头部2112的端部，收容至箭头部2112的底部和竖直板2111之间的空间中，且第二接电面2211a位于箭头部2112的底部和竖直板2111之间的空间外。FIG. 11 is a partial enlarged schematic view of FIG. 6 . As shown in FIG. 11 , the end of thepower strip 22 close to thearrow portion 2112 is accommodated in the space between the bottom of thearrow portion 2112 and thevertical plate 2111 , and the secondpower connection surface 2211 a is located on the side of thearrow portion 2112 . Outside the space between the bottom and thevertical plate 2111.

取电插片22的取电段221具有接电部2211，而接电部2211包括依次相连的第一斜片a1、平片a2和第二斜片a3，那么，如图11所示，第二斜片a3的远离平片a2的端部收容至箭头部2112的底部和竖直板2111之间的空间中，而平片a2远离竖直板2111的表面位于箭头部2112的底部和竖直板2111之间的空间外，其中，平片a2远离竖直板2111的表面即是第二接电面2211a。The power-takingsection 221 of the power-takinginsert 22 has a power-connectingportion 2211, and the power-connectingportion 2211 includes a first inclined sheet a1, a flat sheet a2, and a second inclined sheet a3 that are connected in sequence. Then, as shown in FIG. 11, the first The end of the slanted sheet a3 away from the flat sheet a2 is accommodated in the space between the bottom of thearrow portion 2112 and thevertical plate 2111, and the surface of the flat sheet a2 away from thevertical plate 2111 is located at the bottom of thearrow portion 2112 and thevertical plate 2111. Outside the space between theplates 2111, the surface of the flat sheet a2 away from thevertical plate 2111 is the secondelectrical connection surface 2211a.

在一种示例中，第二斜片a3的远离平片a2的端部收容至箭头部2112的底部和竖直板2111之间的空间中，是为了保护第二斜片a3，使第二斜片a3不会在取电插头40运输和搬运中，出现向偏离竖直板2111的方向翘起的问题。一旦接电部2211向外侧翘起，可能会影响插头20插入至母线槽中。In an example, the end of the second inclined piece a3 away from the flat piece a2 is accommodated in the space between the bottom of thearrow portion 2112 and thevertical plate 2111, in order to protect the second inclined piece a3 and make the second inclined piece a3 The sheet a3 does not lift up in a direction deviating from thevertical plate 2111 during transportation and handling of thepower plug 40 . Once theelectrical connection portion 2211 is lifted outward, it may affect the insertion of theplug 20 into the bus bar.

而第二接电面2211a位于箭头部2112的底部和竖直板2111之间的空间外，是为了避免箭头部2112干涉第二接电面2211a和母线槽中的导电板接触。Thesecond contact surface 2211a is located outside the space between the bottom of thearrow portion 2112 and thevertical plate 2111 to prevent thearrow portion 2112 from interfering with the contact between thesecond contact surface 2211a and the conductive plate in the bus bar.

可见，绝缘板21的箭头部2112起到保护取电插片22的作用，避免取电插片22出现向外翘起的情况。It can be seen that thearrow portion 2112 of the insulatingplate 21 plays a role of protecting the power-takinginsert 22 to prevent the power-takinginsert 22 from tilting outward.

另外，绝缘板21的箭头部2112，在插头20插入至插接槽111的过程中，也会起到引导和导向作用，便于插接。In addition, thearrow portion 2112 of the insulatingplate 21 also plays a guiding and guiding role in the process of inserting theplug 20 into the insertion slot 111, which is convenient for insertion.

如图7和图8所示，插头20还包括压紧件23，压紧件23包括压板231和安全板232。压紧件23为绝缘件，即采用绝缘材料制成。As shown in FIGS. 7 and 8 , theplug 20 further includes a pressingmember 23 , and the pressingmember 23 includes apressing plate 231 and asafety plate 232 . The pressingmember 23 is an insulating member, that is, it is made of insulating material.

压板231位于模块壳体10内，且位于取电插片22的接线段222远离接线固定段212的一侧，压板231、接线段222和接线固定段212相连。Thepressing plate 231 is located in themodule housing 10 and is located on the side of thewiring section 222 of thepower taking insert 22 away from thewiring fixing section 212 .

示例性地，压板231、接线段222和接线固定段212通过螺栓相连，压板231和绝缘板21的接线固定段212将取电插片22的接线段222夹紧，确保取电插片22安装牢固。Exemplarily, thepressing plate 231, thewiring segment 222 and thewiring fixing segment 212 are connected by bolts, and thewiring fixing segment 212 of thepressing plate 231 and the insulatingplate 21 clamps thewiring segment 222 of the power-takinginsert 22 to ensure that the power-takinginsert 22 is installed. firm.

安全板232位于模块壳体10外，安全板232与压板231相连。安全板232位于取电插片22的远离插接段211的一侧，安全板232的高度小于取电插片22的高度，宽度大于或等于取电插片22的宽度。Thesafety plate 232 is located outside themodule housing 10 , and thesafety plate 232 is connected with thepressing plate 231 . Thesafety plate 232 is located on the side of the power-takinginsert 22 away from the plug-insection 211 .

由于安全板232位于取电插片22的远离绝缘板21的一侧，那么，安全板232如果太高，可能会干涉取电插片22与母线槽的导电板的接触，所以，如图8所示，安全板232的高度小于取电插片22的高度。其中，安全板232的高度是安全板232相对于模块壳体10伸出的长度，取电插片22的高度是取电插片22相对于模块壳体10伸出的长度。Since thesafety plate 232 is located on the side of the power-takinginsert 22 away from the insulatingplate 21, if thesafety plate 232 is too high, it may interfere with the contact between the power-takinginsert 22 and the conductive plate of the busbar, so, as shown in FIG. 8 As shown, the height of thesafety plate 232 is less than the height of the power-takinginsert 22 . The height of thesafety board 232 is the length of thesafety board 232 extending relative to themodule housing 10 , and the height of the power-takinginsert 22 is the length of the power-takinginsert 22 extending relative to themodule housing 10 .

而为了进一步提高安全性，安全板232的宽度大于或等于取电插片22的宽度。其中，参考图8所示，安全板232的宽度是沿着多个导电弹片2212的排布方向的长度，取电插片22的宽度也是沿着多个导电弹片2212的排布方向的长度。安全板232的宽度大于或等于取电插片22的宽度，使得安全板232将所有的导电弹片2212都遮挡住。In order to further improve safety, the width of thesafety plate 232 is greater than or equal to the width of the power-takinginsert 22 . 8 , the width of thesafety plate 232 is the length along the arrangement direction of the plurality of conductiveelastic pieces 2212 , and the width of the power-receivinginsert 22 is also the length along the arrangement direction of the plurality of conductiveelastic pieces 2212 . The width of thesafety board 232 is greater than or equal to the width of the power-takinginsert 22 , so that thesafety board 232 blocks all the conductiveelastic pieces 2212 .
