Abstract

A coaxial connector of the type wherein an inner connector member of a female connector is adapted for secure engagement with a connector member of a male connector. The coaxial connector is positioned around the connector member of the male connector and the connector member of the female connector when the coaxial connector is in its locked position. A spring basket with an angular frontal surface is positioned around the connection member of the male connector. A sleeve with an angular internal surface for engaging the angular frontal surface of the spring basket is reciprically positioned around the spring basket and the connection member of the male connector. The sleeve has at least one locking groove that extends substantially parallel to the major axis along a portion of the body thereof. A spring nut is provided with a hollow front end disposed within the sleeve and at least one upstanding locking finger disposed within the at least one locking grove of the sleeve. A spring is partially disposed within the hollow front end of the spring nut, and the spring is positioned between the spring nut and the connection member of the male connector respectively such that when the spring nut is pushed in a forward axial direction relative to the sleeve to lock the coaxial connector, the spring is compressed and the internal angular surface of the sleeve engages the angular frontal surface of the spring basket forcing the spring basket to apply a radially inward force on the connection member of the female connector, holding the female connector in place. The spring provides an axial force on the connection member of the male connector and forces the connection member of the male connector into engagement with the connection member of the female connector.

Claims

1. A coaxial connector of the type wherein a connection member of a female connector is adapted for secure engagement with a connection member of a male connector, wherein said coaxial connector is positionable substantially around said connector member of said female connector, said coaxial connector defining an axial direction along its major axis, said coaxial connector comprising:

a spring basket positioned around said connection member of said male connector, said spring basket having an angular frontal surface;

a sleeve reciprocally positioned around said spring basket and said connection member of said male connector, said sleeve having an internal angular surface for engaging said angular frontal surface of said spring basket, and said sleeve having at least one locking groove extending substantially parallel to the major axis along a portion of the body thereof;

a spring nut having a hollow front end disposed within said sleeve and further being formed with at least one upstanding locking finger disposed within said at least one locking groove of said sleeve; and

a spring partially disposed within said hollow front end of said spring nut, said spring positioned between said spring nut and said connection member of said male connector respectively such that when said spring nut is pushed in a forward axial direction relative to said sleeve to lock said coaxial connector said spring is compressed and said internal angular surface of said sleeve engages said angular frontal surface of said spring basket forcing said spring basket to apply a radially inward force on said connection member of said female connector holding said female connector in place, said spring providing an axial force on said connection member of said male connector and forcing said connection member of said male connector into engagement with said connection member of said female connector.

2. The coaxial connector of claim 1 wherein said spring basket comprises a plurality of tines adapted to radially compress said connection member of said female connector.

3. The coaxial connector of claim 1 wherein the rear end of said spring nut has a plurality of substantially flat sides to facilitate the use of a tool to lock said coaxial connector.

4. The coaxial connector of claim 3 wherein said plurality of substantially flat sides numbers four.

5. The coaxial connector of claim 3 wherein said plurality of substantially flat sides numbers six.

6. The coaxial connector of claim 1 wherein said sleeve has a plurality of locking grooves and said spring nut has as many locking fingers as said sleeve has locking grooves.

7. The coaxial connector of claim 1 wherein said connection member of said male connector is made of electrically conductive material.

8. The coaxial connector of claim 1 wherein said spring basket has an inward-facing lip on the rear portion thereof adapted to fit over and around an outward-facing lip on the frontal portion of said connection member of said male connector.
