Jumper cable

摘要

A jumper cable includes a receptacle mounted on, near or within a battery casing. The receptacle may include a socket having a pair of circular contacts on the inner circumference thereof electrically connected to battery terminals. The device may also include a cable having a plug on each end configured to mate with the receptacle socket. Such a plug may include a larger-diameter ring for engaging the upper contact and a smaller-diameter ring for engaging the lower contact when the plug is inserted into the socket. Accordingly, if a battery needs recharging, a plug is inserted into the receptacle associated with the dead battery and the opposing plug is inserted into a receptacle associated with a charged battery to establish electrical interconnection therebetween. Alternatively, an adapter having a socket and electrical clamps for grasping battery terminals may be used when a receptacle is not connected to one of the batteries.

主权项

1. A system for providing electricity from one battery to another, the system comprising:
a cable having at least two electrical conductors therethrough and having at least two ends; at least two plugs, each located on an end of the cable, each plug configured to receive an end of the cable and the conductors, and each plug comprising an extension having at least two male electrical terminals electrically coupled to corresponding ones of the at least two conductors; a receptacle configured to be electrically coupled to a battery, the receptacle comprising:
electrical conductors electrically connected to corresponding polarity poles of the battery,a socket for receiving the extension of the plug, andat least two female electrical terminals electrically connected to corresponding ones of the electrical conductors of the receptacle, the at least two female terminals corresponding configured to electrically engage corresponding ones of the at least two male terminals when the extension is properly inserted into the socket, wherein the at least two male electrical conductors comprise electrically conductive rings, and one of the at least two conductive rings is located on a distal end of the extension from a body of the plug, and the other of the at least two conductive rings is located at a proximal end of the extension.
