Mechanical and electrical connection interface for a battery containing pack
First Claim
1. A dual-motion separable connection interface, having a first longitudinal axis, for connecting a battery-containing pack with a battery utilizing device, having a second axis, said connection interface comprising:
- a plurality of rigid tabs connected to a base surface of said battery-containing pack, two of said tabs being separated from each other along said first longitudinal axis by a tab space and positioned on each opposite side of said first longitudinal axis, said two tabs directed laterally outwardly a first uniform distance from said longitudinal axis and spaced from said base surface of said battery pack to define lug-receiving slots therebetween;
a plurality of rigid lugs connected to a base surface of said battery utilizing device, two of said lugs separated from each other along said first longitudinal axis by a lug space and positioned on each opposite side of said first longitudinal axis, said two lugs directed laterally inwardly and being spaced a second uniform distance from said longitudinal axis, and being further spaced from said base surface of said battery pack to define tab-receiving slots therebetween;
locking means for preventing motion along said first longitudinal axis of said battery pack relative to said battery utilizing device to prevent separation thereof, said locking means including a movable stem mounted on said battery utilizing device and means for biasing said stem outwardly towards said battery-containing pack from a first position to a second position;
said locking means further including a rigid abutment operatively associated with said stem and connected to, and extending outwardly from said battery-containing pack towards said battery utilizing device;
one of said two tabs being received in one of said lug spaces, one of said two lugs being received in one of said tab spaces, and said abutment moving said stem from said second position inwardly to said first position, when said battery-containing pack is moved towards said battery utilizing device in a direction parallel to said second axis to initiate connection;
said tabs being received in said tab receiving slots, said lugs being received in said lug-receiving slots, and said stem moving from said first position to said second position when said battery-containing pack is moved away from said stem in a direction parallel to said first longitudinal axis to complete connection; and
said battery-containing pack and said battery utilizing device being separable by relative motion therebetween parallel to said first longitudinal axis, followed by relative motion therebetween parallel to said second axis.

Abstract
A connection interface for mechanically and electrically connecting a battery containing pack and a battery utilizing device includes a plurality of outwardly facing lugs positioned on the battery pack to define outwardly facing tab-receiving slots. Cooperating inwardly facing tabs located on the battery utilizing device define inwardly facing lug-receiving slots such that the outwardly facing lugs are received within the inwardly facing lug-receiving slots and the inwardly facing tabs are received within the outwardly facing tab-receiving slots. The mating faces of the tabs and lugs are inclined relative to a medial plane to accomodate accumulated tolerances and assist in providing a rigid mechanical connection. A manually operable latch is provided to prevent unintentional separation of the battery pack and the battery utilizing device.
