Jumper sleeve for connecting and disconnecting male F connector to and from female F connector
View Patent ↗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.
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.
3. 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.
