Detailed Description

A connector comprises a needle base 1 and a terminal rubber shell 2 which are connected in an inserting mode, wherein the part, more than one half, of the terminal rubber shell 2 is inserted into the needle base 1, two terminal wire harnesses 3 are inserted into one end, far away from the needle base 1, of the terminal rubber shell 2, a middle needle 4 matched and connected with the terminal wire harnesses 3 in an inserting mode is inserted into one end, far away from the terminal rubber shell 2, of the needle base 1, a guiding fool-proof groove 1-1 is formed in the inner wall of the needle base 1 along the inserting direction of the terminal rubber shell 2, a guiding rib 2-1 matched and guided with the guiding fool-proof groove 1-1 is integrally formed in the outer wall of the terminal rubber shell 2, a spring piece type clamping hook 3-2 is bent from one side of a terminal of the terminal wire harnesses 3, and a terminal clamping groove 2-2 used for clamping the spring piece type clamping hook 3-2 is formed in the shell wall of the terminal rubber shell 2.

As shown in fig. 1 and 2, when the needle holder 1 and the terminal rubber housing 2 are connected in an inserting manner, the guiding fool-proof groove 1-1 is matched with the guiding rib 2-1 for guiding, so that the guiding effect is achieved, and the condition that the needle 4 is bent due to the fact that the inserting is not aligned in the assembling process is avoided.

The part of the terminal rubber shell 2 which exceeds one half is inserted into the needle base 1, and after the terminal rubber shell and the needle base are inserted, the shaking between the terminal rubber shell and the needle base is avoided. The wrapping property is good.

As shown in fig. 6, the terminal of the terminal harness 3 is bent to one side to form a spring-type hook 3-2, a terminal slot 2-2 for clamping the spring-type hook 3-2 is formed in the shell wall of the terminal rubber shell 2, and after the terminal of the terminal harness 3 is inserted into the terminal rubber shell 2, the spring-type hook 3-2 of the terminal harness 3 is clamped into the terminal slot 2-2 of the terminal rubber shell 2, so that the terminal harness 3 is prevented from falling off.

The inner wall of the needle base 1 is integrally provided with convex needle base grabs 1-9, and the outer wall of the terminal rubber shell 2 is provided with hook grooves 2-9 matched with the needle base grabs 1-9.

As shown in fig. 1 and 2, after the needle base 1 is inserted into the terminal plastic shell 2, the needle base hooks 1-9 are buckled into the hook grooves 2-9, thereby effectively preventing the needle base 1 and the terminal plastic shell 2 from loosening.

The terminal clamping groove 2-2 is arranged on the terminal rubber shell 2 in a penetrating mode inside and outside.

The hook grooves 2-9 and the terminal clamping grooves 2-2 are respectively arranged on two opposite surfaces of the terminal rubber shell 2.

Both sides of the terminal wiring harness 3 are bent inwards to form elastic parts 3-8 for pressing and contacting the pin 4. After the needle stand 1 is spliced with the terminal rubber casing 2, the inner section of the middle needle 4 in the needle stand 1 is inserted into the terminal in the terminal rubber casing 2, and the elastic parts 3-8 bent inwards at two sides of the terminal extrude the outer wall of the inner section of the middle needle 4, so that the terminal is in close contact with the middle needle 4, and the signal transmission is more stable.
