Abstract

The internally locking coaxial connector has a conductive insert disposed in an outer body. The insert has a front flange and a lock washer placed between the front flange and an inwardly extending annular flange at the rear of a coupling nut slidable on the outer body. When a male connector is mated with the female connector, the lock washer applies a continuous tension between the male and female connectors to prevent their separation when exposed to vibration or thermal cycling.

Claims

1. An internally locking coaxial cable connector for connecting a coaxial cable, comprising:

an outer body having a coupling nut slidable on the outer body, the coupling nut having an inwardly extending rear annular flange;

a conductive insert having a substantially cylindrical body having a front end and a rear end, the insert having an outwardly extending annular flange at the front end, the insert being retained in the outer body; and

a lock washer disposed about the insert between the front flange of the insert and the rear flange of the coupling nut;

whereby when the coupling nut is threaded onto a male coaxial connector, the lock washer member is compressed between the front flange of the insert and the rear annular flange of the coupling nut so that the lock washer maintains a tension force between the female and male connectors to prevent separation of the connectors during use.

2. The internally locking coaxial cable connector according to claim 1, wherein the lock washer member is selected from the group consisting of a split ring washer, an external tooth washer, and an internal tooth washer.

3. The internally locking coaxial cable connector according to claim 1, wherein the coupling nut is hexagonally shaped.

4. The internally locking coaxial cable connector according to claim 1, wherein said insert is press fit into said outer body.

5. The internally locking coaxial cable connector according to claim 1, wherein said insert is crimped into said outer body.
