当将所述第一端子组2与第二端子组3安装至所述绝缘本体1内时，首先将所述第二端子组3自后向前安装至所述收容空间120内，所述第二导引块311自后向前在所述第二导引槽1214内向前滑行直至将所述第二端子32的第二接触部321收容在所述底板112内的端子收容槽115内，所述第二凸块3111扣持在所述第二固持槽1217内，所述第二突出部3104扣持在所述穿孔125内时，所述第二端子组3与所述绝缘本体1达成固定。接着将所述第一端子组2自后向前安装至所述收容空间120内，所述第一导引块211自后向前在所述第一导引槽1213内向前滑，所述第三导引块221自后向前在所述第二导引槽1214内向前滑行，直至将所述第一端子23的第一接触部231收容在所述顶板113的端子收容槽115内，所述第一凸块2111扣持在所述第一固持槽1216内，所述第三凸块2211扣持在所述第三固持槽1218内，所述第一突出部2103自后向前收容在所述扣合腔3103内，此时所述第一绝缘块21与所述第二绝缘块31上下相配合收容在所述收容空间120内，所述第一接触部231与所述第二接触部321上下相向收容在所述端子收容槽115内，所述第一抵接面2311与所述第二抵接面3211上下相对暴露在所述插接腔110内。所述第二导引块311与所述第三导引块221沿前后方向对齐，如此使得所述第一端子组2与所述第二端子组3组装更齐整。所述第二凸肋3112、所述第三凸肋2212与所述第二导引槽1214的顶壁相抵接，即与所述分隔部1215相抵接，如此设置，减小了第二绝缘块31、第三绝缘块22与所述绝缘本体1的组装间隙。
所述遮蔽壳体4遮罩在所述绝缘本体1的对接部11上。所述遮蔽壳体4设有壳体顶壁41、自所述壳体顶壁41左右两侧分别向下弯折形成的壳体侧壁42、形成在壳体顶壁41与所述两个壳体侧壁42之间的插接空间40以及自所述壳体顶壁41向后延伸遮罩在所述对接部11的顶板113上方的抵推壁43。所述壳体侧壁42设有向后延伸卡持并定位在所述定位槽1212内的卡臂421、位于卡臂421侧缘的若干倒刺4211以及位于所述壳体侧壁42底部推抵在所述凹槽1141内的推弹臂422，所述推弹臂422自所述壳体侧壁42下边缘撕破成型，设有与所述壳体侧壁42连接的连接部4221以及自所述连接部4221沿所述电连接器100的宽度方向向内缩进的弹抵部4222。所述卡臂421的倒刺4211与所述定位槽1212的内壁相互干涉形成一个定位。所述推弹臂422的弹抵部4222抵持所述凹槽1141的内壁，从而沿前后方向将所述遮蔽壳体4固定在所述绝缘本体1上。如此使得遮蔽壳体4不需要通过上下方向的力量，仅通过前后方向即能达成与绝缘本体1之间的一个相对固定。另外，所述遮蔽壳体4不需要在底部设置与绝缘本体1相扣合的扣合臂，是以当电连接器100焊接至电路板(未图示)上时，只需要调整好所述第一端子23的第一焊接部233与第二端子32的第二焊接部 322达成共面，即可保证所述电连接器100具有较好的共面度，从而保证电连接器100的焊接稳定，不会形成空焊。所述推抵壁43的末端边缘则推抵在所述顶壁122与所述顶板113衔接处的抵接部116上。
如此，本发明电连接器100通过在绝缘本体1的壁部114上设置凸条1211及形成在凸条1211之间的定位槽1212将遮蔽壳体4固定在绝缘本体1上，使得电连接器4100的遮蔽壳体与绝缘本体1在对接方向上达成一个固定配合，同时遮蔽壳体4在上下方向不会对电连接器100造成影响，从而方便电连接器100的焊接部分具有较好的共面度，从而使得电连接器100后续安装方便。
本文使用的例如“上”、“下”、“左”、“右”、“前”、“后”、等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个特征相对于另一个特征的关系。可以理解，根据产品摆放位置的不同，空间相对位置的术语可以旨在包括除了图中所示方位以外的不同方位，并不应当理解为对权利要求的限制。另外，本文使用的描述词“水平”并非完全等同于沿着垂直于重力方向，允许有一定角度的倾斜。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
