detailed description

Please refer to Figures 1 to 4, which show the specific structure of the cable connector of the present invention, which includes an insulating body 10, a conductive terminal 20 accommodated in the insulating body 10, and a cable connected to the terminal 30. in:

The front end of the insulating body 10 is provided with a cuboid insertion portion 11, the insertion portion 11 is used for docking with the pin header connector, and is accommodated in a receiving seat (not shown) of the pin header connector after docking. The front end surface of the insertion part 11 is provided with a socket 12 for inserting pin headers; the rear end of the insulating body 10 is a fixed part 13, and a terminal groove (not shown) is provided on the rear end surface of the fixed part 13. The terminal slot extends forward to the front end of the insertion part 11 and communicates with the socket 12 at the front end of the insertion part. There is also a lock part 14 above the fixed part 13. The lock part 14 is manually pressed when docking. The method is used to lock with the pin header connector to prevent the two from disengaging after they are docked.

The terminal 20 is formed by stamping and bending a thin metal plate, which includes a contact end 21 and a connection end 22. The contact end 21 is provided with a flat lower arm 211, and the middle of the lower arm 211 protrudes upwards with a second A contact part 212, at the rear of the first contact part 212, there is a buckle part 213 to be torn downward, which is used to snap into the insulating body 10 to prevent the terminal 20 from detaching backward; the left and right sides of the lower arm 211 The left side arm 214 and the right arm 215 are respectively bent and extended upward, and the left arm 214 and the right arm 215 are respectively extended forward and provided with elastic second contact parts 216 and third contact parts 217; The upper edge of the right arm 215 is bent backward and extends to the left with an upper arm 218. The upper arm 218 is parallel to the lower arm 211. The upper arm 218, the lower arm 211 and the left and right arms together form a "mouth" Insertion space for pin headers to be inserted. The upper arm 218 extends forward toward the direction of the insertion space and is provided with a fourth elastic contact portion 219.
