【Detailed ways】

The electrical connector of the utility model includes an insulating body 1, a conductive terminal (not shown) housed in the insulating body 1 to electrically connect with a docking connector (not shown), and a wire (not shown) connected to the rear end of the conductive terminal. icon).

Please refer to FIG. 1 and FIG. 4 , the insulating body 1 is integrally formed of insulating material, and has a base 2 and a plugging portion 3 extending forward from the base 2 to be inserted into the mating connector. The base 2 is provided with opposite front end face 21 and rear end face 22 and several terminal holes 23 penetrating through the front end face 21 and rear end face 22 and isolated from each other. The terminal holes 23 penetrate through the front end face 21 and continue to extend forward to form several mutually isolated terminal tubes. 24 . These terminal tubes 24 jointly form the insertion part 3 , and make the cross-sectional area of the insertion part 3 smaller than that of the base part 2 , so that there is a larger gap 34 between the insertion part 3 and the locking arm 4 . The terminal hole 23 and the terminal tube 24 jointly form a conductive terminal channel for receiving the conductive terminal.

The top surface of the base 2 is provided with a locking arm 4 for maintaining the connection state between the insulating body 1 and the docking connector, and is rotatable to realize locking and unlocking. Phase snap. The locking arm 4 is provided with a root (not shown) that is connected to the top surface of the top wall of the insulating body 1 and extends upward, a locking portion 41 extending forward from the root for contacting and locking with the mating connector, and The root portion extends backward for the operator to press and rotate the pressing portion 42 of the locking arm 4 .
