System for Vehicle Jump Starting

摘要

The invention provides a system for jump starting vehicle batteries in which the service end of each of two jumper cables has a self-adjusting locking clamp, and each jumper cable is segmented into two parts that are joined by a plug and socket configured such that the cable parts cannot be incorrectly joined or will be relatively harmless if incorrectly joined. Auxiliary wiring is provided for recharging free-standing source batteries that are used for jump-starting. The system enhances user safety, simplifies making and breaking of electrical connections, and facilitates the use of back-up batteries.

主权项

1. A system for jump starting vehicle batteries, wherein the system comprises:
a) a first jumper cable having the following structure:
i) the cable comprises a source end, a service end, and a reversible coupling that when in a joined state is located at an intermediate position between the two ends;ii) the source end comprises a lead portion for forming a mechanical and electrical connection with a first electrical terminal of a voltage source;iii) the service end is in electrical communication with a locking, self-adjusting clamp;iv) the reversible coupling comprises a plug and a socket that when joined form a mechanically snug union; andv) when the reversible coupling is not joined, the cable is separated into two independent sub-cables, wherein a first sub-cable comprises the source end and a plug end, and a second sub-cable comprises the service end and a socket end; b) a second jumper cable having the following structure:
i) the cable comprises a source end, a service end, and a reversible coupling that when in a joined state is located at an intermediate position between the two ends;ii) the source end comprises a lead portion for forming a mechanical and electrical connection with a second electrical terminal of the voltage source;iii) the service end is in electrical communication with a locking, self-adjusting clamp;iv) the reversible coupling comprises a plug and a socket that when joined form a mechanically snug union; andv) when the reversible coupling is not joined, the cable is separated into two independent sub-cables, wherein a third sub-cable comprises the source end and a socket end, and a fourth sub-cable comprises the service end and a plug end; c) a voltage source that is in electrical communication with a positive electrical lead and a negative electrical lead, wherein
i) the positive electrical lead is further in electrical communication with the source end of the first or second jumper cable;ii) the negative electrical lead is in electrical communication with the source end of the other of the first or second jumper cable;iii) the positive electrical lead of the voltage source is further in electrical communication with a number M of auxiliary electrically conducting cables, wherein M is an integer that has a value selected from the group consisting of 0 and at least 1; andiv) the negative electrical lead of the voltage source is further in electrical communication with a number N of auxiliary electrically conducting cables, wherein N is an integer and has a value that is equal to the value of M.
