[0031] Please refer to the following: Figures 1 to 10 As shown, an electrical connector assembly designed in this application includes an electrical connector 100 and a mating connector 200. The electrical connector 100 includes an insulating body 1, a plurality of conductive terminals 2 fixed within the insulating body 1, and a grounding member 3. The insulating body 1 is integrally injection molded from insulating material and includes a body portion 11 and a locking lug portion 12. The locking lug portion 12 is located on one side of the body portion 11 and forms a gap 10 between it and the body portion 11 in the left-right direction. The gap 10 allows the locking lug portion 12 to elastically deform in the left-right direction, and the locking lug portion 12 is used to achieve mating and locking with the mating connector 200.

[0032] Each conductive terminal 2 includes a fixing section 21 fixed to the body 1, a contact section 22 for mating with the connector 200, and a mating section 23 for mating with a cable or substrate. The conductive terminal 2 is divided into several signal terminals and several power terminals; the signal terminals and power terminals are arranged according to a specific rule. Specifically, in this embodiment, there are four signal terminals (shown as four thinner terminals in the figure) and two power terminals (shown as two thicker terminals in the figure). The four signal terminals are arranged in pairs along the vertical direction; the four signal terminals and the two power terminals are arranged along the horizontal direction; the two power terminals are arranged along the horizontal direction.

[0033] Please refer to the following: Figures 1 to 10As shown, the grounding member 3 is formed from a metal sheet. The grounding member 3 is disposed within the gap portion 10 and fixed to the insulating body 1. The grounding member 3 extends to form an overlapping portion 33 protruding from the insulating body 1 in the left-right direction. The overlapping portion 33 is used to contact the mating structure (i.e., the mating member 9 described below) on the mating connector 200. In a preferred embodiment, the grounding member 3 includes a flat main plate 31, a cantilevered elastic member 32 fixed to at least one of the upper and lower sides of the main plate 31, and a mating leg 34 formed by further extending and bending the main plate 31. The overlapping portion 31 is formed on the elastic member 32. The elastic member 32 is elastically deformable in the left-right direction. The main plate 31 is implanted and fixed within the gap portion 10. In a preferred embodiment, the main plate 31 is attached to the outer side of the body portion 1 in the left-right direction (i.e., the inner wall surface of the gap portion 10 on the side away from the locking lug portion 12 in the left-right direction). There is a pre-set gap (not labeled) between the main board component 31 and the lock lug 12 in the left-right direction. The gap is a space reserved for the deformation of the lock lug 12 in the left-right direction.

[0034] In a preferred embodiment, elastic members 32 are formed on both the upper and lower sides of the main board component 31, and the two elastic members 32 are located on the upper and lower sides of the lock lug portion 12 in the vertical direction.

[0035] In one embodiment, the locking lug 12 is integrally connected to the body 11 at its front end along the mating direction and extends rearward to form a cantilever shape. The elastic member 32 is integrally connected to the main board 31 at its rear end along the mating direction and extends forward to form a cantilever shape. Further, in a preferred embodiment, the insulating body 1 also forms a protective wall portion 13 on the outer side of the elastic member 32 along the vertical direction, and the protective wall portion 13 extends all over the outer side of the elastic member 32 along the mating direction with the mating connector. In the horizontal direction, only the overlapping portion 33 of the elastic member 32 protrudes from the protective wall portion 13.

[0036] Please refer to the reference. Figure 9 and Figure 10 As shown, the front edge of the main board component 31 extends forward along both sides in the vertical direction (at two locations near the upper and lower positions) to form two implantation portions 311, which are inserted forward and fixed into the insulating body 1. Further, one edge at the rear end of the main board component 31 extends and bends in the horizontal direction to form a bent portion 35, and the rear edge of the bent portion 35 is further bent to form the mating pin 34. The bent portion 35 is inserted into the insulating body 1. The mating pin 34 extends and protrudes from the insulating body 1.

[0037] The mating connector 200 includes an insulating base 7, a plurality of mating terminals 8, and mating parts 9. The insulating base 7 forms a mating cavity 70 opening to one end along the mating direction. Each mating terminal 8 includes a fixing portion 81 fixed to the insulating base 7, a contact portion 82 extending from one end of the fixing portion 81 into the mating cavity 70, and a mating portion 83 extending from the other end of the fixing portion 81 out of the insulating base 7. The mating parts 9 are fixed to at least one side (i.e., the left or right side) of the lateral sides of the insulating base 7. The mating parts 9 include a mating surface 90 protruding into the mating cavity 70 in the left-right direction. When the electrical connector 100 mates with the mating connector 200, the electrical connector 100 is inserted into the mating cavity 70, the contact segment 22 contacts the contact portion 82, and the overlapping portion 33 contacts the mating surface 90. Furthermore, the mating parts 9 also extend to form contact pins (unlabeled) protruding from the insulating base 7, corresponding to electrical contact with the circuit board.

[0038] Of course, in other embodiments, two grounding elements 3 can be provided, with each grounding element 3 corresponding to one of the two locking lugs 12. Simultaneously, two mating elements 9 are also provided on the mating connector 200. The grounding elements 3 serve two purposes: firstly, they provide grounding when the electrical connector 100 is mated with the mating connector 200; secondly, they provide support for the locking lugs 12 when pressed, distributing the pressing force and preventing excessive local pressure on the insulating body 1 due to deformation of the locking lugs 12, which could then cause local deformation of the insulating body 1 and inward pressure on the conductive terminals 2. Furthermore, the grounding elements 3 in this application do not increase the overall size of the electrical connector 100, and more importantly, they do not affect the arrangement of the conductive terminals 2.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.

[0040] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
