[0032] In most cases, the insulator 10 of the existing electrical connector 100 and the socket housing 20 are connected and limited by an interference fit. Specifically, a convex block is protrudingly provided on the inner wall of the socket housing 20, and the insulator 10 is provided with a groove and a clamping block corresponding to the convex block. The convex block is clamped in the groove and abuts against the clamping block, thereby connecting the insulator 10 and the socket housing 20. However, in actual operation, when the convex block moves towards the groove, it is easily blocked by the clamping block, and it requires a great deal of force to push the convex block past the clamping block and into the groove, thereby completing the interference fit between the socket housing 20 and the insulator 10, and the assembly difficulty.

[0033] The present utility model proposes an electrical connector 100. Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the electrical connector 100 is plugged into a plug 101, and the electrical connector 100 includes:

[0034] An insulator 10, the insulator 10 includes a connecting portion 11 and a plugging portion 12, the plugging portion 12 is fixedly connected to the connecting portion 11, a limiting convex ring 110 is protrudingly provided on the outer wall of the connecting portion 11, a positioning lug 20 is provided at one end of the plugging portion 12 away from the connecting portion 11, the positioning lug 20 protrudes outward, and an inner jack 121 is provided in the plugging portion 12, and a partial structure of the plug 101 is inserted into the inner jack 121; and

[0035] A socket housing 20, the socket housing 20 includes a sleeve 21 and a fixing portion 22, the sleeve 21 is sleeved on the insulator 10 and abuts against the limiting convex ring 110, one end of the sleeve 21 away from the fixing portion 22 abuts against the positioning lug 20, and the fixing portion 22 is provided with a receiving cavity 220 communicating with the sleeve 21.

Then, the sleeve 21 of the socket housing 20 is sleeved on the insulator 10 and abuts against the limiting convex ring 110, and one end of the sleeve 21 away from the fixing portion 22 abuts against the positioning lug 20, so that the socket housing 20 can be sleeved on the insulator 10 and positioned by the positioning lug 20. After that, glue is filled in the accommodation cavity 220 of the fixing portion 22. The insulator 10 of the electrical connector 100 of the present utility model can also be clamped with the sleeve 21 of the socket housing 20 through the limiting convex ring 110. There is no convex block inside the sleeve 21 of the socket housing 20, thus avoiding the situation where the limiting convex ring 110 blocks the convex block, which is more time-saving and labor-saving. Moreover, the socket housing 20 is positioned by the positioning lug 20 abutting against the insulator 10, and the connection is made by filling glue in the fixing portion 22, ensuring the connection stability between the socket housing 20 and the insulator 10.

The positioning lug 20 is used to block the socket housing 20 from continuing to move away from the connecting portion 11, thereby positioning the socket housing 20 on the insulator 10. The fixing portion 22 of the socket housing 20 is provided with an accommodation cavity 220. After filling glue into the accommodation cavity 220 and the glue is cured, the socket housing 20 is connected to the insulator 10, thereby ensuring the connection stability between the socket housing 20 and the insulator 10.
