Abstract: A board-mountable electrical connector (10, 110) comprises a housing (20, 120) which holds a plurality of contacts (30, 120) in a row. Each of the contacts includes a supporting part (31, 131) that is secured to the housing, a connecting part (33, 133) disposed at one end of the supporting part for connection with a circuit board, and a contact part (32, 132) disposed at an opposite end of the supporting part for electrical contact with a mating body. The contact part extends from the supporting part with successive portions including, first, a downward-facing projection (51) adjacent to the supporting part, a projecting shape (56) extending upward to an apex (56a) and then downward to a bent part (52) at a forward end of the contact part, and an arm part (53) extending upwardly and rearwardly from the bent part to a pair of contact projections (54) which can make electrical connection with the mating body. The contact projections (54) are disposed rearwardly of the apex (56a) of the projecting shape.

Abstract: An electrical connector having an input-output connector part that is connected to an external connector and a power supply connector part that is connected to a power supply.

Abstract: Plug connector (20) has a latch arm (22) intended for engagement with a mating cap connector (70). The latch arm (22) has a latching lug (25) and a cam lug (27) having a tapered surface (26). When the plug connector (20) is connected to the cap connector (70), the cam lug (27) is accommodated in a groove (77) provided in an individual cavity (81) of a cavity opening (72) of the cap connector (70). The latch arm (22) can be bent by inserting a tool in the groove (77) from its end (77a) and pressing on the cam lug (27), thereby releasing the engagement between the latching lug (25) and the cap connector (70) so that the plug connector can be disconnected from the cap connector.
