Description

Background Art

[0002] In related technologies, an electrical connector generally includes an insulating body and a plurality of conductive terminals fixed on the insulating body. The insulating body includes a docking surface and a docking slot penetrating through the docking surface. Each conductive terminal includes a contact portion extending into the docking slot and configured to be electrically connected to a docking connector. The docking connector generally includes a docking tongue plate provided with conductive sheets. During docking, the docking tongue plate is inserted into the docking slot, enabling electrical connection between the conductive sheets and the conductive terminals of the docking connector.

[0003] In order to improve the data transmission rate, a plurality of conductive terminals in related technologies generally include a plurality of pairs of differential signal terminals and ground terminals located on both sides of each pair of differential signal terminals. In some cases, the docking tongue plate is made of a printed circuit board.

[0004] Those skilled in the art can understand that the thickness of the docking tongue plate made of a printed circuit board cannot be designed to be relatively thick due to the influence of the manufacturing process. In other words, when the docking tongue plate is inserted into the docking slot, the docking tongue plate is prone to certain shaking in the up and down direction under external forces, which is not conducive to maintaining docking reliability.

[0005] In addition, and more importantly, as the density of conductive terminals continues to increase, the width of each conductive terminal itself is being reduced. Correspondingly, the width of the conductive sheets on the docking tongue plate is also correspondingly reduced.

[0006] When the docking tongue plate is inserted into the docking slot, in order to avoid difficult insertion of the docking tongue plate due to overly high docking accuracy requirements, the width of the docking slot in related technologies is generally designed to be greater than the width of the docking tongue plate. However, the resulting problem is that when the docking tongue plate is inserted into the docking slot, the docking tongue plate is prone to shift in the width direction of the docking slot, resulting in misalignment between the conductive sheets and the conductive terminals, affecting docking reliability.

[0007] Therefore, it is necessary to improve the electrical connector in related technologies. Summary of the Utility Model

[0093] Compared with the prior art, the first abutting elastic arm 413 and the second abutting elastic arm 423 are respectively located on both sides of the docking slot 150 along the third direction A3 - A3. The third direction A3 - A3 is perpendicular to the first direction A1 and the second direction A2. The first abutting elastic arm 413 protrudes toward the second abutting elastic arm 423 along the third direction A3 - A3, and the second abutting elastic arm 423 protrudes toward the first abutting elastic arm 413 along the third direction A3 - A3. The first abutting elastic arm 413 and the second abutting elastic arm 423 are configured to respectively abut against the first side surface 203 and the second side surface 204 of the docking tongue plate 200, so that during the process of inserting the docking tongue plate 200 into the docking slot 150, the first abutting elastic arm 413 and the second abutting elastic arm 423 can automatically align the docking tongue plate 200. That is, the docking tongue plate 200 can adjust the contact position of the contact portion 6011 with the conductive terminal 60 along the third direction A3 - A3. The present utility model improves the docking reliability and docking accuracy when the electrical connector 100 cooperates with the docking tongue plate 200, and reduces the risk of poor contact caused by the deviation of the docking tongue plate 200 along the third direction A3 - A3. In addition, by using the first abutting elastic arm 413 and the second abutting elastic arm 423 to align the docking tongue plate 200, the tolerance requirements for related parts are reduced, thereby reducing the processing difficulty and improving the product yield. In addition, since the first abutting piece 41 and the second abutting piece 42 of the present utility model are both elastic, they can be repeatedly inserted and removed for use.
