Abstract

A quick self-locking thread coupling connector interface with an inner contact inside the insulator, the insulator inside the outer contact, the coupling nut has at least one convex tooth and a first protruding part on the inner side, the elastic claw has slots corresponding to the convex teeth, a second protruding part and thread are provided on the outer side and the inner side of the elastic claw. The outer contact and the cable connector body are connected fixedly, the elastic claw surrounds rotatably outside the outer contact and is limited axially at the left end by the outer contact. The push nut surrounds the cable connector body and is limited axially, the elastic component is located between the elastic claw, the push nut, and props against the elastic claw and the push nut. The coupling nut surrounds the elastic claw and is connected fixedly with the push nut.

First claim

We claim:

1. A quick self-locking thread coupling interface connector mechanism, comprising an inner contact, an insulator and an outer contact, the inner contact being inside the insulator, the insulator being inside the outer contact, characterized in that, the quick self-locking thread coupling interface connector mechanism further comprises an elastic claw, a cable connector body, an elastic component, a coupling nut and a push nut, the coupling nut has at least one convex tooth and a first protruding part on the inner side, the elastic claw has declining slots whose number is same to that of the convex teeth, a second protruding part and thread are provided on the outer side and the inner side of the elastic claw respectively, the outer contact and the cable connector body are connected fixedly, the elastic claw surrounds rotatably outside the outer contact and is limited axially at the left end by the outer contact, the push nut surrounds outside the cable connector body and is limited axially at the right end by the cable connector body, the elastic component is located between the elastic claw and the push nut and props against the elastic claw and the push nut respectively, the coupling nut surrounds outside the elastic claw and is connected fixedly with the push nut, the convex teeth are within the declining slots respectively, and the second protruding part is located at the left side of the first protruding part;
wherein travel of the convex teeth within the declining slots during rotation of the coupling nut rotates the elastic claw around the cable connector body at a greater rotation rate than the coupling nut.

2. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the elastic component is a spring.

3. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the outer contact and the cable connector body are connected in interference press-fit connection.

4. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the coupling nut and the push nut are connected in interference press-fit connection.

5. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the elastic claw props against the coupling nut.

6. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the number of the convex teeth is 6, the number of the declining slots is 6, or the number of the convex teeth is 10, and the number of the declining slots is 10.

7. The quick self-locking thread coupling interface connector mechanism according to claim 1 , wherein the elastic claw comprises a base and several spring fingers extending from the base, the declining slots are located between two of the spring fingers respectively, the second protruding part and the thread are provided on the outer side and the inner side of the spring fingers respectively, the base surrounds rotatably outside the outer contact and is limited axially at the left end by the outer contact, the elastic component is located between the base and the push nut and props against the base and the push nut respectively.
