Detailed Description

Referring to fig. 1-5, the dual-safety connector of the present invention comprises a plug body 1, wherein the plug body 1 comprises a plug housing 2, a female terminal 3 disposed in the plug housing 2, and a retainer 4 disposed at the rear end of the plug housing 2. Plug housing 2 upper end is equipped with

first buckle

5, 5 rear ends of first buckle extend and have the release to press the portion 6 according to the splenium. The upper end of the retainer 4 is provided with a second buckle 7, the middle part is provided with a first retaining part 8, and the lower end part is provided with a second retaining part 9. The second buckle 7 is connected with the release pressing part 6, the first retaining part 8 is inserted below the release pressing part 6, the second retaining part 9 is inserted into the plug housing 2, and the top of the second retaining part abuts against the female terminal 3.

Preferably, the rear end of the release pressing part 6 is provided with a flange 10, and the second buckle 7 is clamped with the flange 10 to ensure the stability of connection.

Preferably, a slope 11 is provided below the front end of the second buckle 7, so that the second buckle 7 can be tilted by hand to take out the retainer 4.

Preferably, the female terminal 3 has a square insertion hole 12 at the front end and a wire pressing pin 21 at the rear end, and the second holding portion 9 abuts against the upper edge 13 of the square insertion hole 12 so as not to interfere with the wire pressing pin 21 for wire outgoing.

Preferably, the bottom of the square jack 12 is provided with a third buckle 14, and the third buckle 14 is connected with a clamping groove 15 at the bottom of the plug housing 2 in a clamping manner, so as to lock the female terminal 3 once.

Preferably, the second holding portion 9 is composed of a first insertion rod 16, a second insertion rod 17, and a third insertion rod 18 which are arranged at intervals, and the first insertion rod 16, the second insertion rod 17, and the third insertion rod 18 are respectively inserted into three independent inner cavities of the plug housing 2, so as to ensure the stability of connection between the second holding portion 9 and the plug housing 2.
