电连接器及其端子模组 Electrical connectors and terminal modules

【技术领域】【Technical field】

本实用新型涉及一种应用在通信领域内的电连接器及其端子模组。 The utility model relates to an electric connector and a terminal module used in the communication field. the

【背景技术】【Background technique】

电连接器，尤其是高速传输的背板连接器对电连接器的阻抗要求是非常严格的。通常系统厂商会定出一个系统阻抗，而电连接器供应商所提供的电连接器的阻抗需要和系统阻抗相匹配。业界通常的背板连接器包括若干端子模组，每一个端子模组包括若干导电端子及包覆在导电端子上的绝缘块。导电端子本身具有一定的阻抗，但同时外界环境也会对导电端子的阻抗产生影响。具体地讲，空气的阻抗相对比较大，而绝缘材料的阻抗比空气要小，这就要求暴露在空气中的导电端子本身的阻抗要比较小，而包覆在绝缘材料中的导电端子的阻抗要比较大。如此设置，才能实现电流在导电端子内传输时，取任意两个位置，阻抗均相同且保持与系统阻抗相一致。然而，如何实现导电端子的不同位置均能保证阻抗相同是业界普遍存在的技术问题。 Electrical connectors, especially backplane connectors for high-speed transmission, have very strict requirements on the impedance of the electrical connectors. Usually the system manufacturer will set a system impedance, and the impedance of the electrical connector provided by the electrical connector supplier needs to match the system impedance. A common backplane connector in the industry includes a plurality of terminal modules, and each terminal module includes a plurality of conductive terminals and insulating blocks covering the conductive terminals. The conductive terminal itself has a certain impedance, but at the same time, the external environment will also affect the impedance of the conductive terminal. Specifically, the impedance of the air is relatively large, while the impedance of the insulating material is smaller than that of the air, which requires that the impedance of the conductive terminal itself exposed to the air is relatively small, while the impedance of the conductive terminal covered in the insulating material is relatively small. To be relatively large. With such a setting, when the current is transmitted in the conductive terminal, the impedances of any two positions are the same and consistent with the system impedance. However, how to ensure the same impedance at different positions of the conductive terminals is a common technical problem in the industry. the

所以有必要设计出一种电连接器其端子模组以解决上述技术问题。 Therefore, it is necessary to design a terminal module of an electrical connector to solve the above technical problems. the

为解决上述技术问题，本实用新型还可以采用如下技术方案：一种端子模组，用以安装于电连接器内，所述端子模组包括绝缘块及固定于绝缘块上的若干导电端子，所述导电端子位于共同的第一平面内，所述导电端子包括被镶埋在绝缘块内的第一部分及暴露于空气中的第二部分，所述第一部分包括相对设置且与第一平面平行的两个第一表面及相对设置且与第一平面垂直的两个第二表面；所述第二部分包括相对设置两个第三表面及相对设置且与第三表面垂直的两个第四表面；所述两个第二表面之间的距离小于两个第一表面之间的距离，且所述两个第二表面之间的距离小于两个第三表面之间的距离或者小于两个第四表面之间的距离。 In order to solve the above technical problems, the utility model can also adopt the following technical solutions: a terminal module for installation in an electrical connector, the terminal module includes an insulating block and a number of conductive terminals fixed on the insulating block, The conductive terminals are located in a common first plane, and the conductive terminals include a first part embedded in the insulating block and a second part exposed to the air, and the first part includes oppositely arranged and parallel to the first plane.

【具体实施方式】【Detailed ways】

图1至图3揭示了本实用新型的电连接器100及其端子模组2。所述电连接器100包括绝缘本体1及安装于绝缘本体1上的若干端子模组2。绝缘本体1包括竖直的安装部11、自安装部11延伸的第一、第二突出部12、13及自安装 部11的上端朝另外一侧延伸的定位部14。在本实施方式中，所述第一、第二突出部12、13分别自安装部11的上、下端且朝一侧延伸而成。所述第一、第二突出部12、13之间形成暴露于空气中的收容空间110。所述安装部11设有贯穿的且与收容空间110连通的若干通孔111(参图3)。所述定位部14设有并排设置的定位槽141。 1 to 3 disclose theelectrical connector 100 and theterminal module 2 of the present invention. Theelectrical connector 100 includes aninsulating body 1 and a plurality ofterminal modules 2 mounted on theinsulating body 1 . Theinsulating body 1 includes avertical mounting portion 11, first andsecond protrusions 12, 13 extending from themounting portion 11, and apositioning portion 14 extending from the upper end of themounting portion 11 to the other side. In this embodiment, the first and secondprotruding parts 12 and 13 extend from the upper and lower ends of theinstallation part 11 and extend toward one side. Areceiving space 110 exposed to the air is formed between the first and second protrudingparts 12 and 13 . Themounting portion 11 is provided with a plurality of through holes 111 (see FIG. 3 ) penetrating through and communicating with thereceiving space 110 . Thepositioning portion 14 is provided withpositioning slots 141 arranged side by side. the

请参图4至图6所示，所述端子模组2包括若干导电端子21、包覆于导电端子21上的绝缘块22及扣持于绝缘块22上的屏蔽壳体23。请参图7至图8所示，所述导电端子21是由金属料带3冲压、扭转而成。所述金属料带3为扁平状且在未冲压前包括相对设置的光滑面31。在冲压过程中，垂直光滑面31将金属料带3冲压成预定形状后遗留下来的为下料面32。若未经过特殊处理，光滑面31要比下料面32光滑得多，因此光滑面31更适合用以充当与对接连接器的导电端子配合的接触面。 Referring to FIGS. 4 to 6 , theterminal module 2 includes a plurality ofconductive terminals 21 , aninsulating block 22 covering theconductive terminals 21 , and ashielding shell 23 buckled on theinsulating block 22 . Please refer to FIG. 7 to FIG. 8 , theconductive terminal 21 is formed by stamping and twisting themetal strip 3 . Themetal strip 3 is flat and includes oppositesmooth surfaces 31 before stamping. During the stamping process, theblanking surface 32 remains after the verticalsmooth surface 31 stamps themetal strip 3 into a predetermined shape. Without special treatment, thesmooth surface 31 is much smoother than theblank surface 32 , so thesmooth surface 31 is more suitable for serving as a contact surface for mating with the conductive terminals of the mating connector. the

所述导电端子21包括蜿蜒的中间部211、自中间部211前端向前突出的接触部212及自中间部211底端向下延伸的安装脚213。所述接触部212穿过安装部11的通孔111而延伸入收容空间110内。所述中间部211包括相对设置的两个第一表面(在本实施方式中为第一光滑面)24及相对设置的且垂直第一光滑面24的两个第二表面(在本实施方式中为第一下料面)25。所述两个第一光滑面24分别与金属料带3的光滑面31一致。所述中间部211在蜿蜒过程中的任意两段的宽度及厚度均相同，以保证中间部211本身具备同样的阻抗。所述接触部212包括相对设置的两个第三表面(在本实施方式中为第二光滑面)26及相对设置且垂直第二光滑面26的两个第四表面(在本实施方式中为第二下料面)27。所述接触部212为直条状且相对于中间部211呈90度扭转。扭转的目的在于将金属料带3的光滑面31转变成用以与对接连接的导电端子(未图示)相配合的接触面(即第二光滑面26)。光滑的接触面可以降低插入力，同时保证插接的平稳性。 Theconductive terminal 21 includes ameandering middle portion 211 , acontact portion 212 protruding forward from a front end of themiddle portion 211 , and amounting leg 213 extending downward from a bottom end of themiddle portion 211 . Thecontact portion 212 extends into thereceiving space 110 through the throughhole 111 of themounting portion 11 . Themiddle portion 211 includes two first surfaces (in this embodiment, first smooth surfaces) 24 oppositely arranged and two second surfaces (in this embodiment For the first blanking surface) 25. The two firstsmooth surfaces 24 are respectively consistent with thesmooth surfaces 31 of themetal strip 3 . The width and thickness of any two sections of themiddle part 211 during the meandering process are the same, so as to ensure that themiddle part 211 itself has the same impedance. Thecontact portion 212 includes two third surfaces (in this embodiment, the second smooth surface) 26 opposite to each other and two fourth surfaces (in this embodiment, the second smooth surface 26 ) opposite to each other and perpendicular to the secondsmooth surface 26. The second cutting surface) 27. Thecontact portion 212 is straight and twisted at 90 degrees relative to themiddle portion 211 . The purpose of twisting is to transform thesmooth surface 31 of themetal strip 3 into a contact surface (ie, the second smooth surface 26 ) for mating with a butt-connected conductive terminal (not shown). The smooth contact surface can reduce the insertion force while ensuring the stability of mating. the

所述接触部212暴露在空气中，而中间部211是镶埋在绝缘块22内，由于空气的阻抗大而绝缘块22的阻抗小，所以为了保证在外在因素的影响下，导电端子21仍能够保持相同的阻抗，本实用新型将中间部211的宽度W1设置为小于中间部211的厚度T1，并且使中间部211的宽度W1设置为小于接触部212的宽度W2。如此设置，相当于将中间部211的宽度W1设置为比金属料带3的厚 度还要窄，便于增加中间部211本身的阻抗。另外，由于接触部212的宽度W2相对较大，进而使接触部212本身的阻抗相对于中间部211的阻抗要小。所述两个第一光滑面24之间的距离T1小于两个第二光滑面26之间的距离W2。这种设计方式可以使导电端子21在被镶埋在绝缘块22内后，各段均保持相同的阻抗且与系统阻抗相匹配。当然，做为本实用新型的进一步改进，所述中间部211的厚度T1也可以被设置为小于接触部212的厚度T2，目的与以上的设计相同。所述接触部212的后端且靠近中间部211的位置设有加厚的固定部28，所述固定部28的厚度均大于两个第一光滑面24之间的距离T1及两个第一下料面25之间的距离W1。所述固定部28固定于绝缘本体1的通孔111内，从而可以使导电端子21可以稳定固持在绝缘本体1上；另外，所述加厚的固定部28也可便接触部212相对于中间部211做扭转。 Thecontact portion 212 is exposed to the air, while themiddle portion 211 is embedded in the insulatingblock 22. Since the impedance of the air is large and the impedance of the insulatingblock 22 is small, in order to ensure that theconductive terminal 21 remains To maintain the same impedance, the present invention sets the width W1 of themiddle part 211 to be smaller than the thickness T1 of themiddle part 211 , and makes the width W1 of themiddle part 211 smaller than the width W2 of thecontact part 212 . Such setting is equivalent to setting the width W1 of themiddle part 211 to be narrower than the thickness of themetal strip 3, so as to increase the impedance of themiddle part 211 itself. In addition, since the width W2 of thecontact portion 212 is relatively large, the impedance of thecontact portion 212 itself is smaller than the impedance of themiddle portion 211 . The distance T1 between the two firstsmooth surfaces 24 is smaller than the distance W2 between the two second smooth surfaces 26 . This design can make theconductive terminal 21 embedded in the insulatingblock 22 , each section maintains the same impedance and matches the impedance of the system. Of course, as a further improvement of the present invention, the thickness T1 of themiddle part 211 can also be set to be smaller than the thickness T2 of thecontact part 212, the purpose is the same as the above design. The rear end of thecontact part 212 and the position close to themiddle part 211 are provided with a thickened fixingpart 28, and the thickness of the fixingpart 28 is greater than the distance T1 between the two firstsmooth surfaces 24 and the distance T1 between the two first smooth surfaces. The distance W1 between the blanking surfaces 25 . The fixingpart 28 is fixed in the throughhole 111 of the insulatingbody 1, so that theconductive terminal 21 can be stably held on the insulatingbody 1; in addition, the thickened fixingpart 28 can also make thecontact part 212 relativelySection 211 does the twist. the

在本实用新型的实施方式中，所述被镶埋在绝缘块22内的中间部211被视为第一部分，而暴露于绝缘块22之外的接触部212被视为第二部分。所述导电端子21的中间部211共同的位于第一平面(未标号)内。就细部结构看，所述第一光滑面24与第一平面平行，而第一下料面25与第一平面垂直。当然，在本实用新型的其他实施方式中，所述第二部分可以为未被镶埋在绝缘块22内的其他中间部211。 In an embodiment of the present invention, themiddle part 211 embedded in the insulatingblock 22 is regarded as a first part, and thecontact part 212 exposed outside the insulatingblock 22 is regarded as a second part. Themiddle portions 211 of theconductive terminals 21 are commonly located in a first plane (not labeled). As far as the detailed structure is concerned, the firstsmooth surface 24 is parallel to the first plane, while thefirst blanking surface 25 is perpendicular to the first plane. Of course, in other embodiments of the present invention, the second part may be othermiddle part 211 not embedded in the insulatingblock 22 . the
