Embodiment Construction

[0012] figure 1 A jumper cable connector 1, (or more commonly referred to as electrode clamp) represents a preferred embodiment of a jumper cable. Button 2 is provided on the appreciable part of the connector. A light 3, preferably an LED, is also provided on the connector to provide light when connected to the battery post. The rear of the jumper cable connector 1 contains a battery compartment 5 for containing one or more batteries that provide voltage to the lamp 3 .

[0013] Connector cables 6 are connected to clamping contacts 7 in a conventional manner. The arrangement and operation of the connector (electrode clamp) 1 to the battery terminals and connector wires is conventional.

[0014] figure 2 express figure 1 An exploded perspective view of the jumper cable connector. The battery compartment 5 comprises a hollow compartment 5b connecting the rear part 4 of the device 1 . Hollow box 5b contains lead wires 8 and 9 which are connected to switch 2 and lamp 3 . ...

Abstract

A battery jumper cable having a light source which may be activated independently from a connection with a battery to be charged. At least one of the jumper cable connectors includes a voltage source, a switch and a light. Simple activation of the switch will cause the voltage source to illuminate the light thus providing sufficient lighting to identify the polarity of battery posts and establish a proper connection between the connector and battery terminal. In an alternate embodiment, the voltage source is provided from an external booster battery. An electrical connection is established between opposite cables. The switch closes a circuit between the external booster battery and the light thereby providing voltage to the light. The connector may be used as a flashlight to illuminate a connection area without the need for contact with the battery to be charged.

Description

technical field [0001] The present invention relates to a pair of jumper cables, and more particularly to a pair of jumper cables having lights having an independent power source for selectively energizing the lights prior to connection to a battery to be charged . Background technique [0002] The use of battery cables is well known in the art. Clearly, these devices have the potential to be harmed if an arc occurs between the battery's poles. Therefore, it is important to connect the jumper cables to the correct battery terminals for safety and to eliminate power shorts. Numerous attempts have been made to develop jumper cable indication systems that effectively indicate proper battery connection. Many of these systems use LEDs, or other lights, that light up when the jumper cables are properly connected. Among these are US Patents: 4,938,712; 6,868,688; and 4,840,583; each of which discloses such a system, and are incorporated herein by reference. However, each of th...
