A lever-type connector ( ) has a frame-shaped holder ( ) for accommodating auxiliary connectors ( ). A lever ( ) is mounted on the holder ( ) and is adapted to connect the lever-type connector ( ) and a male connector ( ) by cam action effected as the lever ( ) is rotated. The lever ( ) extends along only one wall surface of the holder ( ). Thus, wires ( ) and the lever ( ) are unlikely to interfere with each other. Further, the lever ( ) is accommodated in a recess ( ) of the holder ( ) and is held from opposite sides along a direction of the rotational axis. Thus, the lever ( ) will not deform along the direction of the rotational axis and will not detach from the holder ( ).

Lever-type connector

A terminal unit (TU) includes a battery terminal ( ) mounted at the leading end of a wiring harness ( ), and a holder ( ) mounted on the wiring harness ( ) at a position distanced from the battery terminal ( ). A current sensor ( ) is transported separately from the terminal unit (TU) to a connection site to a battery (B). The battery terminal ( ) is introduced through the current sensor ( ) and the current sensor ( ) then is coupled with the holder ( ) at the connection site. This operation is performed at a position distanced from the battery (B), and hence can be performed smoothly without being hindered.

A connector assembly has a split-type connector ( ) configured for insertion into a receptacle ( ) of a mating connector ( )i. The split-type connector ( ) has a holder ( ) and auxiliary connectors ( ) that can be mounted in the holder ( ). A retainer ( ) is mountable in the holder ( ) and can be moved from a first position where the auxiliary connectors ( ) can be mounted in the holder ( ) and a second position where the auxiliary connectors ( ) are locked. The receptacle ( ) has dovetail grooves ( ) and the holder ( ) has dovetail ribs ( ) that engage to prevent the receptacle ( ) from deforming away from the outer surface of a holder ( ).

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 has a mating section formed in such a manner that two plate members and , which individually extend from a base , are superimposed on one another by folding on the base . The mating section has flat sections extending in a mating direction P, wherein outer surfaces of the two plate members - and - are formed flat. A tip of one of the two plate members is folded to overlap a tip of the other plate member . This feature makes it hard to open the plate members and when the male contact is mated with the female contact.
