DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Coaxial cable connectors are generally straight in shape and extend along the same central axis as the attached cable. Thus, for cables with connectors mounted to mate with ports,
Cables must be placed approximately perpendicular to the port plane. Cable routes must take this into account, and may require additional space. The reason is that the cable itself is not flexible enough to provide a bent shape at the connector. It would be desirable to provide a connector that could be positioned with respect to the port, rather than vertically, so that the coaxial cable would mate with the port.

The connector serves to interconnect the coaxial cable to the port. The terminal features a generally 90 ° bend and has a first end for receiving a conductor therein and a second end perpendicular to the first end extending outside the connector for connection to a port. ing. In use, a coaxial cable having a prepared end is inserted into the open end of the integrated body. The center conductor of the coaxial cable connector mechanically and electrically connects to the terminal. The shield of the coaxial cable is electrically connected to the port. Next, the open end of the body is swaged to mechanically secure the cable in the connector. The second embodiment is similar to the first embodiment, except that the insert has been removed and the stem is pressed into the second hole of the one-piece body with the nut rotatable around the stem.
