Electrical board module and its connector

Abstract

An electrical board module includes a frame with a plurality of linearly arranged windows, and an annular groove formed at the junction of adjacent windows. Electrical boards extending into the annular groove are disposed on each window. Two bidirectional connectors are disposed between any two adjacent electrical boards, embedded in the frame and with grooves accommodating adjacent sides of the two electrical boards, and electrically connected to each other via conductive plates. Two unidirectional connectors are disposed on the outer sides of the two outermost electrical boards, embedded in the frame and with grooves accommodating the outer periphery of the corresponding electrical board, and electrically connected to the fixed electrical board via conductive plates. Thus, the bidirectional and unidirectional connectors allow the periphery of each electrical board to suspend above the annular grooves, facilitating subsequent filling of the annular grooves with sealant, and enabling electrical connection of the electrical boards using the same connectors, which is beneficial for assembly.
