Abstract
An electrical connector with a threaded shell which screws on to a threaded connector body, and including an O-ring disposed between the shell and body. The O-ring is made of an elastic material and is placed over the threaded portion and against a shoulder of the connector body so that when the shell is screwed onto the threaded portion of the connector body the O-ring is compressed between the end of the shell and the body shoulder, thereby providing increased friction between the shell and connector body to resist unscrewing of the shell from the body by vibrations and similar random forces.
Claims7
An electrical connector, comprising:
- a connector body having at least one pin at a first end, the pin electrically insulated from the connector body and having a receiver for receiving an electrical wire, and having an exterior surface of the first end defining a first diameter, the connector body having an outside threaded portion having an outer diameter less than the first diameter, the connector body having a shoulder between the exterior surface and the threaded portion;
- a flexible O-ring disposed over the threaded portion adjacent to the shoulder;
- and
- a shell having an inside threaded end having an edge for threadably engaging the outside threaded portion of the connector body, adjacent to the O-ring, whereby the O-ring is compressed between the shoulder of the connector body and the edge of the shell when the shell is screwed onto the threaded portion of the connector body, the O-ring thereby providing increased friction between the connector body and shell for resisting unscrewing forces.
A method for assembling an electrical connector, comprising the steps of:
- inserting a connector body having at least one pin on a first end, the pin electrically insulated from the connector body and having a receiver for receiving an electrical wire, and having a shoulder adjacent to a threaded portion into an elastic O-ring,
- placing a shell having an edge adjacent to a threaded portion of the connector body;
- screwing the shell onto the threaded portion of the connector body;
- and
- compressing the O-ring between the shell edge and the connector body shoulder, the O-ring thereby providing increased friction between the connector body and shell for resisting unscrewing forces.
