The invention provides a connector including first and second beams, first and second conductive plates, and an urging device. The first and second beams extend substantially in parallel with each other and include first and second accommodating recesses, respectively. The first and second recesses are opposed to each other and open toward distal end sides of the first and second beams. The first and second conductive plates are to be accommodated in the first and second accommodating recesses, respectively, and removably insertable from the distal end sides into the first and second accommodating recesses, respectively. The urging device urges the first and second conductive plates in directions close to each other.
