Coaxial cable connector with pop-out pin
View Patent ↗An electrical connector having a front end for attachment to a terminal and a back end for attachment to a coaxial cable includes a body, a post mounted within the body; and a contact assembly movably mounted within the post. The contact assembly includes a guide, a pin mounted to the guide, and a clip mounted to the pin for making electrical and mechanical contact with the center conductor of the coaxial cable. The contact assembly moves longitudinally toward the front end of the connector, such that the front end of the pin moves from a first position completely within the body to a second position at least partially protruding from the body, as the connector receives the coaxial cable. The guide has an opening for the center conductor, which is viewable to a user during attachment until the center conductor enters the opening.
1. An electrical connector for attachment to a coaxial cable, the coaxial cable comprising a center conductor, a dielectric layer surrounding the center conductor, and an outer conductor surrounding the dielectric layer, the electrical connector comprising:
a body disposed about a longitudinal axis;
a generally tubular support made of electrically insulative material disposed within the body;
a post fixedly mounted within the body, the post comprising an inner surface defining a cylindrical bore; and
a contact assembly mounted within cylindrical bore of the post and capable of moving longitudinally relative to the body, the contact assembly comprising:
a dielectric guide; and
a pin mounted to the guide;
wherein the pin is distinct from the dielectric guide;
wherein, in a first state, the pin is supported by the generally tubular support and the dielectric guide is spaced away from the generally tubular support; and
wherein, in a second state, the pin is supported by the generally tubular support and the dielectric guide is closer to the generally tubular support than in the first state.
2. The electrical connector of claim 1 wherein the dielectric guide is proximate the generally tubular support in the second state.
3. The electrical connector of claim 1 wherein longitudinal movement of the pin relative to the generally tubular support is limited.
4. The electrical connector of claim 1 wherein the generally tubular support is capable of limiting longitudinal movement of the contact assembly relative to the body.
5. The electrical connector of claim 1 wherein the pin projects out of the generally tubular support in the first state.
6. The electrical connector of claim 1 wherein the pin projects out of the generally tubular support in the second state.
7. The electrical connector of claim 1 wherein the pin projects out of the generally tubular support in the first state, and wherein the pin projects further out of the generally tubular support in the second state than in the first state.
8. The electrical connector of claim 1 wherein the pin does not project out of the body in the first state.
9. The electrical connector of claim 1 wherein the pin projects out of the body in the second state.
10. The electrical connector of claim 1 wherein the pin does not project out of the body in the first state, and wherein the pin projects out of the body in the second state.
11. The electrical connector of claim 1 wherein the body further comprises a flange that limits longitudinal movement of the generally tubular support.
12. The electrical connector of claim 1 wherein the generally tubular support does not move longitudinally relative to the body.
13. The electrical connector of claim 1 wherein, in the first state, a front portion of the pin is supported by the generally tubular support, and, in a second state, a rear portion of the pin is supported by the generally tubular support.
14. The electrical connector of claim 1 wherein the body is metallic.
15. The electrical connector of claim 1 wherein the post is metallic.
16. The electrical connector of claim 1 wherein the generally tubular support maintains the pin at the longitudinal axis.
17. The electrical connector of claim 1 wherein the bore of the post is adapted to receive at least part of the coaxial cable.
18. The electrical connector of claim 1 wherein the post comprises a rear portion capable of being inserted into the coaxial cable between the dielectric layer and the outer conductor.
