In this way, the pressing beam portion 5220 can better prevent the tail portions 32 , 42 of the electrical connector terminal set 100 from breaking away from the receiving groove 522 upwards. The inserting portion 524 is provided with two inserting holes 525 extending from front to back and arranged left and right. The inserting holes 525 are located above the pressing beam portion 5220 for inserting the inserting piece 53 . The front end of the insertion part 524 is provided with a number of supporting ribs arranged at intervals from left to right and extending vertically in the front-rear direction to support the rear ends of the bent parts on the head 31, 41 of the electrical connector terminal set 1. 526, in this embodiment, the blanking part 321 of the composite terminal 3 and the vertical part 4 of the curved single terminal 4 are the bent parts on the head 31, 41 of the electrical connector terminal group 1, so set, the When the electrical connector terminal set 1 is plugged by the butt connector, the bent parts of the head 31 , 41 of the conductive terminal 1 are not easily deformed, thereby effectively prolonging the service life of the electrical connector 100 .

The connector 53 is provided with a beam-shaped base 531 extending left and right, two clamping arms 532 extending forward from the left and right ends of the base 531 , and a self-base arranged left and right and located between the two clamping arms 532 . 531 are two inserting arms 534 extending forward. The base portion 531 leans against the top of the pressing beam portion 5220 and leans forward against the rear end of the insertion portion 524 of the second insulating body 52 , and the insertion arm 534 is used for insertion into the insertion portion 524 . In the two insertion holes 525 of the connecting portion 524 , the front end of the insertion arm 534 is provided with a convex portion 535 that expands to both sides, so that the insertion arm 534 can be prevented from leaving the insertion hole 525 backward. The clamping arm 532 is located on both sides of the insertion portion 524 of the second insulating body 52 to be clamped in the buckling groove 515 of the first insulating body 51 , and the front end of the clamping arm 532 protrudes inward with a The hook portion 533 , as shown in FIG. 3 , the front end of the locking groove 515 is inwardly recessed and communicates with the receiving cavity 516 . In this way, the hook portion 533 of the clamping arm 532 can cooperate with the front end of the buckling groove 515 to prevent the clamping arm 532 from detaching from the buckling groove 515 backward, so that the first and second insulating bodies 51, 52 The connectors 53 are firmly combined together.

The electrical connector 100 is suitable for including but not limited to USB Type C or FPC electrical connectors.

The series of detailed descriptions listed above are only specific descriptions for the feasible implementation modes of the present utility model, and they are not used to limit the protection scope of the present utility model. Embodiments or modifications should be included within the protection scope of the present utility model.
