CIRCUIT BOARD TO CIRCUIT BOARD CONNECTOR WITH VERTICAL AND LONGITUDINAL ASSEMBLY ALIGNMENT FEATURES

An electrical connector assembly and a battery pack system utilizing the electrical connector assembly are described. The electrical connector assembly includes a first connector body defining a first locating pin and a second connector body defining a first location socket. The first connector body may also define a second locating socket and the second connector body may define a second locating pin having the same shape as the first locating pin and first locating socket. The electrical connection between the first and second connector bodies is established by a conductor connected between the terminals. The locating pins and locating sockets provide lateral location of the terminals relative to each other. The terminals or the conductor may define a U-shaped portion that provides longitudinal and vertical assembly tolerance of the terminals in the first connector body relative to the terminals in the second connector body.
