A shielding layer 13 is provided between the two terminal modules to shield the two terminal modules. The signal interference problem that may occur between the two rows of terminals 21, 22 (ie, the first terminal 21 and the second terminal 22) on the terminal module 20, the terminal has a connecting portion 212 extending out of the shell and is exposed on the shell and is flat with the shell. Aligned contact portion 211. The above elements will be described in detail below.
请结合图3所示，所述外壳10为由导电金属材料制成的导电一体式结构，比如导电材料注塑成型。所述外壳10具有安装部15、向前延伸的对接部11及自外壳10后端面向对接部11方向凹设的容置腔12。容置腔12由一个屏蔽层13间隔成两个子容置腔121。As shown in FIG. 3 , the housing 10 is a conductive integrated structure made of conductive metal materials, such as injection molding of conductive materials. The housing 10 has a mounting portion 15 , a docking portion 11 extending forward, and an accommodating cavity 12 recessed from the rear end of the housing 10 toward the docking portion 11 . The accommodating cavity 12 is separated into two sub-accommodating cavities 121 by a shielding layer 13 .
两个端子模组20的结构大致相同，即第一端子模组20a及第二端子模组20b，其分别插入外壳的子容置腔121。每个端子模组包括端子21、22及与端子21、22注塑成型于一体的绝缘体23，端子埋设在绝缘体23内。所述端子包括裸露于绝缘体23前端的一个表面的接触部211及裸露于绝缘体23的后端面的连接部212。绝缘体23的前端边缘向前凸伸有一排凸块231，绝缘体23在靠近后端面处在相对接触部的另一表面设有加厚部232。在其他实施例中，端子模组可以设置成一个整体的端子模组，比如讲第一端子模组与第二端子模组在外壳的安装部位置由塑胶连接，中间留有一条细缝，该端子模组具有一排第一端子21及一排第二端子22，在端子模组插入容置腔后，屏蔽层13插入细缝且位于第一端子与第二端子之间。但是，第一、第二端子与屏蔽层还是由一定的绝缘体的塑胶部分间隔开。The structures of the two terminal modules 20 are substantially the same, that is, the first terminal module 20a and the second terminal module 20b, which are respectively inserted into the sub-accommodating cavity 121 of the housing. Each terminal module includes terminals 21 , 22 and an insulator 23 injection-molded integrally with the terminals 21 , 22 , and the terminals are embedded in the insulator 23 . The terminal includes a contact portion 211 exposed on a front surface of the insulator 23 and a connecting portion 212 exposed on a rear surface of the insulator 23 . A row of projections 231 protrude forward from the front edge of the insulator 23 , and a thickened portion 232 is provided on the other surface of the insulator 23 near the rear end surface opposite to the contact portion. In other embodiments, the terminal module can be set as an integral terminal module. For example, the first terminal module and the second terminal module are connected by plastic at the mounting part of the housing, leaving a thin slit in the middle. The terminal module has a row of first terminals 21 and a row of second terminals 22. After the terminal module is inserted into the accommodating cavity, the shielding layer 13 is inserted into the slit and located between the first terminals and the second terminals. However, the first and second terminals are still separated from the shielding layer by a certain plastic part of the insulator.
下面结合组装过程描述电连接器的细节部分。参图4及图5，所述外壳的对接部11具有相对设置的第一对接面111与第二对接面112，所述第一对接面111与第二对接面112分别凹设有与容置腔12连通的第一缺口部1111与第二缺口部1121，所述对接部11设有面向容置腔的内表面113。所述外壳10进一步包括延伸入容置腔12的上述屏蔽层13，屏蔽层13自对接部11的内表面113一体延伸形成，其前端与对接部的前内壁面一体相连，其侧边与对接部的两个相对内侧壁面相连(图4清楚显示)，从而将容置腔12分成两个相同的子容置腔121，恰好可以收容结构相似的上述两个端子模组20a、20b。屏蔽层在于容置腔内壁面相连处的尺寸较厚，分别形成第一与第二加强部131、132，而位于第一、第二端子之间的部分则形成屏蔽部133。所述第一加强部131与第一对接面111之间形成位于容置腔12前端的固定槽141，第二加强部132与第二对接面112之间亦形成位于容置腔12前端的固定槽141。所述第一与第二加强部131、132的厚度大于该屏蔽部133的厚度，所述第一加强部131与屏蔽部133的交界处设有导引斜面134。The details of the electrical connector are described below in conjunction with the assembly process. 4 and 5, the docking portion 11 of the housing has a first docking surface 111 and a second docking surface 112 oppositely arranged, and the first docking surface 111 and the second docking surface 112 are recessed and accommodated respectively. The cavity 12 communicates with the first notch portion 1111 and the second notch portion 1121 , and the abutting portion 11 is provided with an inner surface 113 facing the accommodating cavity. The housing 10 further includes the above-mentioned shielding layer 13 extending into the accommodating cavity 12. The shielding layer 13 is integrally formed by extending from the inner surface 113 of the docking portion 11, its front end is integrally connected with the front inner wall of the docking portion, and its side is connected to the The two opposite inner wall surfaces of the upper portion are connected (shown clearly in FIG. 4 ), thereby dividing the accommodating cavity 12 into two identical sub-accommodating cavities 121, which can just accommodate the above two terminal modules 20a, 20b with similar structures. The shielding layer is thicker at the part where the inner wall of the accommodating cavity connects, forming the first and second reinforcing parts 131 and 132 respectively, and the part between the first and second terminals forms the shielding part 133 . A fixing groove 141 at the front end of the accommodating cavity 12 is formed between the first reinforcing part 131 and the first abutting surface 111, and a fixing groove 141 at the front end of the accommodating cavity 12 is also formed between the second reinforcing part 132 and the second abutting surface 112. Groove 141. The thickness of the first and second reinforcing parts 131 and 132 is greater than the thickness of the shielding part 133 , and a guiding slope 134 is provided at the junction of the first reinforcing part 131 and the shielding part 133 .
参图5及图7，所述两个端子模组20自后端面插入子容置腔121，直至所述第一、第二端子的接触部211分别裸露于外壳10的第一与第二缺口部1111、1121内，接触部分别裸露于第一、第二对接面111、112，所述端子模组20前端的凸块231则分别插入固定槽141，可以稳定地定位端子模组。所述导引斜面134导引端子模组向对接面方向移动，所述加厚部232前端的导引面进一步使得端子末端向对接面方向移动，使得所述第一、第二端子的接触部211分别裸露于该第一、第二缺口部。两个端子模组20分别抵靠于加强部132并被两侧的加强部132左右固定，如图7清楚显示。此时，端子模组20的接触部211与缺口部间隔开而未搭接，可以确保导电的接触部不会接触导电的外壳。同时，两个端子模组之间由屏蔽层13间隔开。最后，如图8所示，在所述第一与第二缺口部1111、1121及固定槽141、142之间填充有塑胶材料，形成绝缘层161、162，塑胶材料密封端子模组20，使得塑胶材料与对接部11的对接面相平齐，所述端子模组20抵持于容置腔的内侧面，这样使得端子模组牢牢固定于外壳内。同时，塑胶块17阻挡于容置腔12的后端面，防止端子模组未定位牢靠，而滑出容置腔。5 and 7, the two terminal modules 20 are inserted into the sub-accommodating cavity 121 from the rear end until the contact portions 211 of the first and second terminals are respectively exposed in the first and second notches of the housing 10 In the parts 1111, 1121, the contact parts are exposed on the first and second mating surfaces 111, 112 respectively, and the protrusions 231 at the front end of the terminal module 20 are respectively inserted into the fixing grooves 141, so that the terminal module can be positioned stably. The guide slope 134 guides the terminal module to move toward the mating surface, and the guiding surface at the front end of the thickened portion 232 further moves the terminal end toward the mating surface, so that the contact portions of the first and second terminals 211 are respectively exposed in the first and second notches. The two terminal modules 20 respectively abut against the reinforcement part 132 and are fixed left and right by the reinforcement part 132 on both sides, as clearly shown in FIG. 7 . At this time, the contact portion 211 of the terminal module 20 is spaced apart from the notch and does not overlap, which can ensure that the conductive contact portion does not contact the conductive shell. Meanwhile, the two terminal modules are spaced apart by the shielding layer 13 . Finally, as shown in FIG. 8, plastic material is filled between the first and second notches 1111, 1121 and the fixing grooves 141, 142 to form insulating layers 161, 162, and the plastic material seals the terminal module 20, so that The plastic material is flush with the mating surface of the mating portion 11 , and the terminal module 20 is held against the inner surface of the accommodating cavity, so that the terminal module is firmly fixed in the housing. At the same time, the plastic block 17 blocks the rear end surface of the accommodating cavity 12 to prevent the terminal module from sliding out of the accommodating cavity if it is not positioned securely.
本发明电连接器100的外壳10设置延伸入容置腔的屏蔽层13，且将屏蔽层13设置于两端子模组之间，可减少端子模组之间的信号干扰。The housing 10 of the electrical connector 100 of the present invention is provided with a shielding layer 13 extending into the accommodating cavity, and the shielding layer 13 is arranged between the two terminal modules to reduce signal interference between the terminal modules.
