[0003] The existing connector generally inserts the outer end of the male end into the opening of the outer end of the female end, so that the male terminal of the male end is inserted into the female terminal of the female end to complete the connection. However, this plug-in method is less firm and easy to loosen.

[0004] The existing Chinese patent with publication number CN220440024U discloses a push-pull snap-fit ​​electrical connector, which specifically discloses that the center of the front end face of the electrical connector is symmetrically fixedly connected with guide rods on both sides, the front end face of the electrical connector is provided with a plug, and the center of the rear end face of the plug is symmetrically provided with guide grooves on both sides, and the center of the two side walls of the plug is respectively fixedly connected with fixing rods at the rear end, and the rear ends of the two fixing rods and the two side walls of the electrical connector are respectively provided with snap-fit ​​mechanisms, and the snap-fit ​​mechanisms include four support blocks, two limit rods, two return springs, two position blocks, two push rods, two transverse and two limit grooves, and four support blocks. Although the device can solve the above-mentioned defect of loose plugging of the male end and the female end, the device still has the following defects: 1. Adding a fixing rod and a snap-fit ​​mechanism to the traditional connector increases the production cost, and the fixing rod is located outside the female end and extends a certain length, which has been damaged.

[0005] For this purpose, we designed an electrical connector. Utility Model Content
