Electrical connector with integral strain relief and mount, and overtemperature indicator
First Claim
1. An electrical plug-in connector, said connector having a multi-part case, and an electrical cord terminated in said case, said case being split generally longitudinally into two parts, one of said parts having means for substantially entirely surrounding and securing said electrical cord at an end thereof, said other part being shorter in length than said one part, said other part matching and lining up with a connection end of said one part, and said one of said parts having said cord securing means including a cord end substantially larger than the cord end of the other of said parts so that the cord end of said one part comprises substantially the entirety of the cord end of said connector case.

Abstract
An electrical connector of generally clam-shell construction includes an integral mount at the cable end of only one connector half to thereby provide an integral mount for a flexible strain relief. Additionally, a P.C. board mounted overtemperature sensing circuit is contained within the connector to sense an overtemperature condition inside the connector itself and illuminate an LED to provide a visual indication to an operator that an overtemperature condition has occurred. The LED remains illuminated so long as the connector is connected in circuit with the battery being charged and will remain so even after the battery charger'"'"'s automatic circuitry reduces or cuts off charger power to the circuit. The circuit automatically resets itself for reuse upon disconnection (and cooling) of the connector from the charging circuit.

- 13. An electrical plug-in connector, said connector including means for sensing an overtemperature condition as said connector is connected to a source of electrical power, and means for indicating the sensed occurrence of said overtemperature condition, said indication means including means for maintaining said indication despite a reduction of temperature of said connector below said overtemperature condition.
- 21. An electrical plug-in type, male connector for a battery charger, said connector having a case comprised of two parts, each of said parts being approximately half of said case except that one of said parts has an integral mounting hole for a strain relief at an end thereof, and a P.C. board mounted overtemperature circuit with an LED, said LED extending through a hole in said case, said circuit having means to sense an overtemperature condition in said case as said connector is connected to a source of electrical power and illuminate said LED in response thereto.
