Polarity indicating connector for battery jumper cables
First Claim
1. Polarity indicating connector for battery jumper cables, comprisinga. a pair of mateable housings with each housing including a pair of contacts positioned in separate passages extending therethrough, said contact having cable attaching means at one end and contact blades at another end with the free end of the blades being curved back to provide a cup-shaped end, and a pair of electrically conductive spring members with one end staked in the housings and with the other end received in the cup-shaped end on the contacts;
- b. polarity indicating means including an indentation in one housing with a pair of apertures extending from the indentation through the housing to the spring members, a pair of U-shaped displacement contacts having wire-receiving slots at the free ends thereof, said contacts being positioned in the apertures with the bights engaging the spring members to effect electrical contact with the contacts through said spring members, and with the free ends extending into the indentation, and an LED electrically connected to the free ends of the contacts by wires being received in said slots; and
c. a cover having an opening therethrough, said cover covering the indentation with the opening exposing the LED.

Abstract
A two-piece connector for battery jumper cables wherein the connector portions each indicate the positive and negative battery terminals to which the cables from the connector are to be connected. The connector further includes a two state LED device which provides a green light when the cables are connected to a battery with polarity in the manner stated on the connector and a red light when the polarity is reversed. The circuitry, therefore, is contained directly in each connector half. The connector halves are hermaphroditic so that they can not be connected in reverse polarity condition.
