【Detailed ways】

1 to 5 are various views of the electrical connector 100 of the present invention.

The electrical connector 100 includes an insulating body 1 , a plurality of terminals 2 accommodated in the insulating body 1 , and a metal shell 3 located on the outer layer of the insulating body 1 .

The insulating body 1 includes a rectangular base body 11 and a tongue plate 12 extending forward from the front end of the base body 11 . The base body 11 is formed with upper and lower surfaces 111 , 112 , left and right side surfaces 113 , 114 and front and rear end surfaces 115 , 116 . The base body 11 is provided with a drawer-shaped clamping groove 117 passing through the front and rear end surfaces 115 , 116 , and the bottom surface of the clamping groove 117 is provided with an embedded groove 118 . A terminal accommodating groove 10 is formed between the tongue plate 12 and the base body 11 .

The terminal 2 includes a welding portion 21 , a fixing portion 22 adjacent to the welding portion 21 , and a cantilever-shaped connecting portion 23 extending from the fixing portion 22 . The plane of the welding portion 21 and the plane of the fixing portion 22 are perpendicular to each other. The connecting part 23 is provided with a contact 231, the fixed part 22 is provided with a deformation hole 221, and one side of the deformation hole 221 is convex, and the fixed part 22 is provided with a stab 222 at the edge of the deformation hole 221, and the fixed part 22 is provided with a card. The edge of the deformed hole 221 of the thorn 222 is arched. A clamping block 223 is provided at a position where the fixing portion 22 of the terminal 2 is opposite to the hook 222 .

The metal shell 3 is cylindrical and includes a pair of opposite plate surfaces 31 and a side wall 32 adjacent to the plate surfaces 31 . The metal shell 3 extends backward from the plate surfaces 31 and has a protective cover inserted into the insulating body 1 . The rotation plate 33 extends backward from the side wall 32 with a plug 321 that can be inserted into the insulating body 1. The plane where the anti-rotation plate 33 is located is perpendicular to the plane where the plug 321 is located. The anti-rotation plate 33 is provided with a square groove 331. The two The rear edge of the square groove 331 is opposite to the concave buckle 332 .

When the electrical connector 100 is assembled, the terminal 2 is assembled in the insulating body 1, and the stab 222 of the fixing part 22 of the terminal 2 penetrates into the terminal receiving groove 10 of the insulating body 1, so that the terminal 2 can be stably accommodated in the insulating body 1.
