Abstract: There is provided a male contact having improved electrical contact reliability with a female contact. The male contact has a mating section capable of being formed compactly using a plate member having a plate thickness satisfying a desired strength requirement. The male contact 1 has a mating section 10 formed in such a manner that two plate members 11 and 12, which individually extend from a base 20, are superimposed on one another by folding on the base 20. The mating section 10 has flat sections 15 extending in a mating direction P, wherein outer surfaces of the two plate members 11-1 and 12-1 are formed flat. A tip 13 of one of the two plate members 12 is folded to overlap a tip 14 of the other plate member 11. This feature makes it hard to open the plate members 11 and 12 when the male contact is mated with the female contact.

The plug (20) is formed along its longitudinal axis with a wire insertion hole (13) that can be brought into close resilient contact with the outer surface of the (W). An inner diameter of the wire insertion hole (13) aligned with the fixing portion (12) is smaller than the one at the side of trunk (11), whereby the fixing portion (12) can be held strongly in close contact with the outer surface of the wire (W).

Abstract: A lever-type connector assembly has mating female and male connectors (10, 50). The female connector (10) has a lever (40) with a cam plate (41) and a resilient lock (46) that is deformable within the plane of the cam plate (41). The resilient lock (46) engages a receiving portion (33A) on the female connector (10) for holding the lever (40) at an initial position. The connector (50) has an unlocking rib (55) that deforms the resilient lock (46) out of engagement with the receiving portion (33A). As a result, the lever (40) can rotate for connecting the connectors (10, 50). Since the resilient lock (46) deforms in the plane of the cam plate (41), there is no need to provide space for deformation of the resilient lock (46) along a thickness direction of the cam plate (41).
