The housing 10 is provided with an actuating portion 144 on each side of the terminal 12 corresponding to each spring arm 521. In the present embodiment, each of the actuating portions 144 is preferably a slope. However, the utility model is not limited thereto, and the actuator 144 may be a protruding structure capable of interfering with the moving stroke of the elastic arm 521 and moving the elastic arm 521. Thereby, when the pull handle 51 is pulled backwards, the locking member 52 is moved backwards, and the actuating portions 144 push the elastic arms 521, so that the elastic arms 521 move outwards along the transverse direction of the housing 10. When the cable connector is mated with a mating connector, the mating connector can be locked by hooking the cable connector through a structure such as a lock hook, and the hooking position of the mating connector preferably corresponds to the elastic arm 521, so that the mating connector can be withdrawn to release the cable connector by moving the elastic arm 521 outwards.

In addition, the lower housing 14 has a receiving slot 143 corresponding to each elastic arm 521 at both sides of the terminal 12, a return spring 60 is disposed in each receiving slot 143, and a moving plate 5211 is protruded from each elastic arm 521 toward the lower housing 14 corresponding to the return spring 60. The locking member 52 is fitted over the terminal 12 of the lower housing 14, and the pull tab 51 is located outside the terminal 12 and straddles the wiring harness a. Specifically, the connecting arm 522 is located below the lower case 14, and the two resilient arms 521 are respectively attached to the left and right sides of the lower case 14 to cover the receiving groove 143. The shifting piece 5211 of each elastic arm 521 is located in the accommodating groove 143, and the return spring 60 is elastically clamped between the shifting piece 5211 and the accommodating groove 143. Thereby, the locking member 52 is moved backward when the pull knob 51 is pulled backward, and simultaneously the corresponding return spring 60 is pushed by each finger 5211 to be compressed, and the unlocking assembly 50 is restored to the position by the elastic force of the return spring 60 when the pull knob 51 is released. It should be noted that, in the embodiment, the number of the return spring 60 and the accommodating groove 143 corresponding to each elastic arm 521 is two and the two are arranged in a mirror image, but the utility model is not limited to the number.
