Abstract

A jumper sleeve for connecting and disconnecting a male F connector to and from a female F connector includes a wrench portion and a grip portion. The wrench portion has a leading end, a trailing end, and a hollow main body located between the leading end and the trailing end. The main body of the wrench portion internally has a hexagonally shaped portion corresponding to a shaped outer surface of a rotatable connecting ring of the male F connector. The grip portion has a rear end and a front end connected to the trailing end of the wrench portion, and has a plurality of circumferentially spaced externally convex sections, each of which has a radially inward key formed near the rear end thereof. The jumper sleeve provides greater mechanical advantage to produce sufficient torsion force, enabling easy installation and removal of the male F connector.

Claims

1. A jumper sleeve being fitted on a F-type coaxial cable structure for connecting and disconnecting a male F connector of the F-type coaxial cable structure to and from a female F connector on an electronic device, the male F connector having a connecting ring rotatably provided at a front end thereof, and a coaxial cable being extended from a rear end of the male F connector, the connecting ring having a threaded inner surface and a shaped outer surface, the jumper sleeve comprising:

a wrench portion being a tubular element having a leading end, a trailing end, and a hollow main body located between the leading end and the trailing end;

a shaped portion being formed in the main body for receiving the shaped outer surface of the connecting ring therein; and

a grip portion being a hollow element having an annular front end and a rear end, the front end of the grip portion being connected to the trailing end of the wrench portion, and the grip portion having a plurality of circumferentially spaced externally convex sections;

wherein each of the externally convex sections of the grip portion has a radially inward protruded inner key formed near the rear end of the grip portion to prevent the male F connector from slipping out of the rear end of the grip portion;

wherein when the jumper sleeve is mounted to an assembled male F-Type cable structure and the male F-Type connector is fully inserted into the jumper sleeve, a gripping force may be applied to the grip portion to permanently affix the jumper sleeve to the male F-Type connector.

2. The jumper sleeve as claimed in claim 1, wherein the wrench portion is formed on an inner surface with a stepped shoulder portion, so as to prevent the shaped outer surface of the connecting ring from protruding beyond the wrench portion.

4. The jumper sleeve as claimed in claim 1, wherein the shaped portion in the main body of the wrench portion is a hexagonally shaped portion corresponding to the shaped outer surface of the connecting ring of the male F connector.

3. (canceled)
