In a waiting-side connector, a coveris detachably mounted on the rear surface of a female housing. Leg piecesprojecting from the female housingare formed with guide railsto define an insertion pathfor a bracket. A lock protrusionis formed on the rear surface of the cover, whereas a lock holeis formed in the bracket. Independent follower pinsare provided on the female housingand the cover. In an area of a cam grooveof each leverof a movable-side connectorcorresponding to a final stage of a separating operation, cam surfacesfor individually pushing the follower pinsare formed such that the coveris less separated than the female housing

Connector

Follower pins of a female housing are fitted into cam grooves of a lever supported by axles on a male housing These two housings and can be fitted together or separated by means of pivoting the lever between a starting position, and an ending position. An upper supporting member is formed at a right side of a hood and a lower supporting member When the lever is pivoted to the starting position or the ending position, a tip thereof is supported by the supporting member or respectively, thereby protecting this tip from contact with other components, etc. The supporting members and protrude into dead space relative to the position of the housing Consequently, no extra space is required when the housing is placed in position, yet the lever has increased length and angle of travel.

Lever-type connector

A waterproof connector is provided with a moving support plate without requiring an increase in size of the connector. A moving plate ( ) has a shape whereby a side wall ( ) protrudes upwards from circumference edges of a base plate ( ) having maintaining holes ( ) adapted to receive tabs ( ) of male terminal fittings. This moving plate ( ) can be inserted in a movable manner within a hood ( ) of male housing ( ). A first sealing ring ( ), for sealing the space between the moving plate ( ) and an outer circumference face of the female housing ( ), is formed on an attachment base of an inner circumference face of an anterior end ( A) of the side wall ( ). A second sealing ring ( ), for sealing the space between the moving plate ( ) and in inner circumference face of the posterior end ( B) of the side wall ( ). These sealing rings ( ) and ( ) are formed in a unified manner, by means of two-component molding, on the moving plate ( ).

Connector with terminal protective plate having internal and external sealing members

Retainers,provided on an electrical connector housing,become approximately level with an outer wall of the connector housing,when terminal fittings,are inserted and, moreover, are maintained in a second stopping position whereby these retainers,are engaged with the terminal fittings,. Outer faces of the terminal fittings,interfere with the retainers,as these terminal fittings are inserted, thereby causing the retainers,to bend resiliently and move to a position whereby they protrude form the outer wall of the connector housing,. Then, after the terminal fittings,have reached a correct inserted position, the retainers,return resiliently to their second stopping position, engage with the terminal fittings,, and prevent these terminal fittings,from being removed. At the point when the terminal fittings,are about to be inserted, the retainers,remain in a state whereby they do not protrude from the outer face of the connector housing,. Consequently, there is no danger that the retainers,will be moved inadvertently to an obstructing condition.

A lever type connector is provided with a lever that has a rotatable or pivotable range wider than its rotatable or pivotable range during the connection of male and female housings without changing a moving stroke of a moving plate. The lever,is enabled to rotate from a connection start position to a connection end position located opposite from a standby position, and each cam groove,is formed with a play area,C for preventing the lever,from being interfered with by cam pins,of a moving plate,when the lever,is rotated or pivoted toward the standby position. Since the cam grooves,of the lever,and the cam pins,of the moving plate,do not interfere with each other while the lever,is rotated or pivoted from the connection start position to the standby position, the moving plate,will not move together with the lever

Lever type connector

A miniaturized lever is provided for an electrical lever type connector having a moving plate to support protruding terminals. Recesses are provided on cam pins of a moving plate and these fit together with cam pins of a female connector housing. As a result, the cam pins of the moving plate and female connector housing are unified, and in this unified state are then fitted in a cam groove of a lever. Consequently only a single cam groove is required, compared to the prior art where two cam grooves corresponding to the two cam pins are necessary.

A lever-type electrical connector has a moving support plate 15 to prevent bending of protruding male terminals of a male connector housing 11. The support plate 15 has external flanges 20,42 to prevent inward movement of cam pins 18,41 due to the application of external force to the base of the support plate 15. The plate 15 may have a continuous upstanding wall 17 to further resist distortion due to external force.

A connector is provided in order to enhance a tactile sensation by providing a restoring force to a lock piece and further to attain an original locking function at the fitting of both a male and female connector housing. A dome covering the upper edge of a lock piece is formed on a female housing, and an arm which protrudes rearwardly and which can be elastically deformed is affixed to the dome. A projecting contact part protrudes downwardly at the end of the arm and closely contacts the upper edge of the lock piece. When the male and female housings are interfitted, a gaff part on the lock piece engages a protrusion on the male housing and swings upwardly, and in accordance with it, elastically deforms the arm by pushing the projecting contact part. When the male and female housings are normally interfitted, the lock piece restores to its original position and is locked by engagement of the gaff part with the backside of the protrusion. The lock piece forcefully restores to its original position by receiving the restoring elastic force of the arm, therefore causing the end of the gaff part to snap onto the upper face of the male housing to generate a loud sound and an enhanced tactile sensation.

A connector includes first and second connector housings which are fitted together. A seesaw or lever-type lock piece is provided in one of said connector housings and a hooking part is provided on the other connector housing for being hooked by a first downward projection of the lock piece. A detecting member is mounted for free sliding movement along the upper face of the lock piece. After a fitting operation of both housings is carried out, the detecting member is pushed forwardly. When the connector housings are in an incomplete fitted position or state, since the first downward projection is mounted on the hooking part and the lock piece is in an oblique position, the pushing of the detecting member is prevented and an incomplete fitted state is detected. When the detecting member is further pushed in, one of the housings is pushed in with the lock piece and is properly fitted. The detecting member is retained just at the position of the front end of the lock piece and the connector housings are thereby double locked.
