Battery pack connection
DCFirst Claim
1. A releasable connection for a battery pack or the like comprising a relatively flat male plate and a relatively flat female plate,said plates being adapted to be releasably locked together in connected position;
- said female plate including a plurality of keyholes with each having an opening and a depending slot, and at least one elongated terminal, said terminal and keyhole slots being elongate in the same direction;
said male plate including a plurality of spaced headed projections with there being one for each keyhole and with each projection having head and leg portions, and at least one elongated mating terminal;
said male plate being positioned abutting the female plate with the leg portions of the projections being located in the slots of the associated keyholes and with the one terminal within the mating terminal;
releasable locking means on said female plate for engaging at least one of the headed projections in at least one of said keyhole slots to lock said plates in connected position by preventing relative movement between said plates in the direction of said keyhole slots by maintaining the engagement of said locking means with said headed projection until said locking means is released; and
safety latch means on said female plate for preventing movement of said releasable locking means upon engagement of said locking means with said headed projection.

Abstract
A battery pack connection consists of a substantially flat male plate having a plurality of spaced headed projections and female electrical terminals carried within a projecting housing and a substantially flat female plate having a plurality of keyholes designed to facilitate receiving the projections and male electrical terminals positioned within a recess for engagement with the female electrical terminals. At least one rotatable member is mounted on the female plate and has a pin that engages over the head of a corresponding projection to enable locking of the plates in both their electrical and mechanical connected relationship. Upon rotation of the member, the pin is moved out of engagement with the projection to enable uncoupling of the plates. A safety latch can be activated to abut the rotatable member when the plates are locked together to preclude inadvertent decoupling.
