[0040] Example:

[0041] A small pitch single row connector with secondary lock, such as Figure 1-10 As shown, it includes a female end 2, a male end 1 is inserted at the front end of the female end 2, the male end 1 includes a male end body 1.1, a plurality of wiring grooves 1.13 are opened at the front end of the male end body 1.1, a hanging tooth 1.14 is arranged in the wiring groove 1.13, a wiring terminal 1.3 is inserted in the wiring groove 1.13 and fixed by a male end locking piece 1.2, the female end 2 includes a plurality of female end needle seats, the female end needle seat includes a spring contact groove 2.2 and a hanging platform 2.1 above it, a rivet foot 1.32 is arranged above the front end of the wiring terminal 1.3, a terminal buckle 1.31 is arranged below the middle of the wiring terminal 1.3, and an elastic contact piece 1.33 is arranged at the rear end of the wiring terminal 1.3, the elastic contact piece 1.33 is inserted into the spring contact groove 2.2, and the terminal buckle 1.31 cooperates with the hanging tooth 1.14 to limit.

[0042] Furthermore, the elastic contact piece 1.33 and the spring contact groove 2.2 are interference fit.

[0043] Furthermore, an elastic outer hook 1.12 is provided on the top of the male end body 1.1, and the elastic outer hook 1.12 cooperates with the hanging platform 2.1 to limit the position.

[0044] Furthermore, buckles 1.11 are provided on both sides of the male end body 1.1, and hooks 1.22 are provided on both sides of the male end locking piece 1.2. The buckles 1.11 are engaged and connected with the corresponding hooks 1.22.

[0045] Furthermore, a plurality of anti-retraction support blocks 1.21 are provided in the male end locking piece 1.2, and the anti-retraction support blocks 1.21 press the corresponding rivet pressing feet 1.32 to prevent the connection terminal 1.3 from falling off.

[0046] In a possible implementation, the male elastic outer hook 1.12 is used in conjunction with the female needle holder hanging platform 2.1, and the electrical conduction between the male end 1 and the female end 2 is achieved by interference contact between the male terminal elastic contact piece 1.33 and the female spring contact groove 2.2.

[0047] Furthermore, the male end body hanging tooth 1.14 cooperates with the male end terminal undercut 1.31; the hook 1.22 of the male end locking piece 1.2 cooperates and fixes with the buckle 1.11 of the male end body 1.1, and the anti-retraction support block 1.21 of the male end locking piece 1.2 cooperates and supports with the riveting foot 1.32 of the terminal;
