  • Protected automotive battery access terminals
    Patent number: 4807895
    Abstract: A pair of electrical terminals conveniently accessible from the exterior of an automobile or truck and connected electrically to the positive and negative poles of a battery within the engine compartment of the vehicle. The terminals are located within a recessed chamber formed in the vehicle body with an insulated separator located between the terminals and supporting the terminals. To protect against tampering and environmental conditions a cover door with a locking latch encloses the recessed chamber. Preferably the door chamber, terminals and electrical connections to the battery poles are of sufficient size to permit the use of heavy gauge jumper cables for quick charging of the battery and quick starting of the vehicle. By locating the terminals in a chamber external to the engine compartment or other battery compartment of the vehicle the likelihood of a battery explosion caused by an inadvertent spark in connecting or disconnecting the jumper cables is greatly lessened, if not entirely eliminated.
