The present invention is directed to a compact lever-type connector in which a lever can be fixed in specified positions. Lever (50) is installed on a side surface (24) of a housing (18) so that the lever (50) is free to pivot. The lever (50) has a lever main body (56) and an extensible lever (58) which is attached to the lever main body (56) so that the extensible lever (58) can be extended and retracted. Respective grooves (80), (82) and (84) are formed in the lever main body (56) and extensible lever (58). An arcuate rib (90) is formed on the housing (18). Only when the extensible lever (58) is extended are the grooves (80) (82) and (84) aligned so that the rib (90) can be accommodated by these grooves, thus allowing pivoting of the lever (50). In the initial and final positions of the lever (50), the extensible lever (58) can be extended and retracting relative to the lever main body (56).

A connector 10, 30' has a guide member 70, 60' movably latched in its housing 12, 40'. The guide member 70, 60' is used to guide and align contact portions of male contacts. The guide member 70, 60' has a plate 72 formed with a large number of through-holes 84 to pass the male contacts therethrough. Preferably, the guide member 70 is formed with side plates 78 at both sides of the plate 72 perpendicular thereto. Latching arms 92, 94, 96 are stemmed from the free ends of the side plates 78 and extend in the opposite direction, thereby minimizing the apparent length of the latching arms 92, 94, 96 which engage with respective projections 100, 102, 104 on the inner wall of the connector housing 12.

Electrical connector having contact guide member

When double-lock member (42a) is in an incompletely inserted state, the contacting part (43a) projects from the plug housing (20). In this incompletely inserted state, the plug housing (20) and cap housing (30) are in a position prior to being tentatively latched to each other, and the contacting part (43a) of the double-lock member (42a), which has not been inserted into the plug housing (20), makes contact with the end (30a) of the cap housing (30), so the drawing together of the plug housing (20) and the cap housing (30) cannot proceed. Also, the end of the bolt case (14) in which the bolt (12) is clasped into the hole (22) of the plug housing, and the bolt (12) is held in the plug housing (20) by the bolt stop plate (40). Therefore, the bolt (12) is held in an unengaged state in the when in the incompletely inserted state.
