Battery pack for sterile transfer battery container
View Patent ↗A rechargeable battery pack for a surgical powered instrument. The battery pack is an assembly of individual cylindrical battery cells and has its electrical terminals in the form of sockets recessed within the body of the pack in the interstices between the cells. The terminal sockets are adapted to receive elongated plugs and enable the pack to be handled while minimizing the risk of shorting.
1. A battery pack comprising:
a plurality of cylindrical battery cells assembled into a predetermined configuration wherein the axes of said cells are all aligned with each other, said configuration having interstices between the individual cells, said interstices comprising elongated channels; and
electrically positive and negative socket means inserted into selected ones or said interstices, each sock means adapted to fit within selected channels and adapted to mateably engage a plug, each said socket means comprising a pair of opposed, elongated leaf spring contact members having a substantial point contact therebetween and adapted to receive therebetween an elongated plug; and
a hollow, elongated retaining member adapted to be received within each said channel and adapted to retain said leaf spring contact members within said retaining member, each said hollow, elongated retaining member having a proximal end, defining an opening for receiving a plug, and an open distal end, further comprising a retaining plug adapted to prevent motion of said leaf spring contact members out of said open distal end; and
securing means to secure said contact members from movement relative to said channel.
