[0033] The existing electrical connector 100 is provided with two terminal assemblies, each of which is provided with a row of solder pins. When assembling, after the two terminal assemblies are installed together, the two rows of solder pins will be arranged in a row. However, since there is no positioning structure between the two terminal assemblies that can position each other, the flatness of the two rows of solder pins after being arranged in a row is poor, which leads to a high defect rate in subsequent welding.

[0034] The utility model provides an electrical connector 100. Please refer to Figures 1 to 3 In one embodiment of the present utility model, the electrical connector 100 comprises:

[0035] Housing 10;

[0036] A first terminal assembly 20, the first terminal assembly 20 is arranged on the housing 10, the first terminal assembly 20 comprises a fixing member 21 and a plurality of first welding legs 22, the plurality of first welding legs 22 are mounted on the fixing member 21, a plurality of positioning grooves 211 are arranged on a side of the fixing member 21 away from the housing 10, and the positioning grooves 211 are arranged to avoid the first welding legs 22; and

[0037] The second terminal assembly 30 is arranged in the housing 10 and connected to the first terminal assembly 20. The second terminal assembly 30 includes a limit member 31 and a plurality of second welding legs 32.

The second welding legs 32 are arranged parallel to the first welding legs 22.

[0038] The housing 10 is a metal housing 10 , which has the functions of shielding and increasing strength, and is used to accommodate the first terminal assembly 20 and the second terminal assembly 30 .

[0039] The technical solution of the utility model is to set a plurality of positioning grooves 211 on the fixing part 21 of the first terminal assembly 20, and set a plurality of positioning protrusions 310 on the limiting part 31 of the second terminal assembly 30; the first terminal assembly 20 and the second terminal assembly 30 are assembled together, and the positioning protrusions 310 are limitedly installed in the positioning grooves 211.
