摘要： An electrical connector assembly includes a male connector housing (4) having shafts (43) projecting from its opposite side walls respectively. A locking hood (2) is mounted on the shafts (43) to be rotatively moved about them between a lying state that it lies along the top of the male connector housing (4) and a rising state relative to the top of the male connector housing (4). The locking hood (2) has on its distal end a cam projection (13) lifted up with insertion of a female connector housing (9) into the male connector housing (4). In a temporary latching state of the connector housings (4, 9), the cam projection (13) is engaged with a cam block (14) of the female connector housing (9) so that the female connector housing (9) is displaced. The rear end of the locking hood (2) extends obliquely downwardly to provide an elastic member (202). When the locking hood (2) is rotatively moved to rise up, the elastic member (202) abuts against the top of the male connector housing (4) to elastically deform, urging the locking hood (2) to the former state. As a result, the locking hood (2) can be prevented from becoming an obstacle in the storage of the connector assembly and can be prevented from easily dropping off.

摘要： A pair of connector housing may be temporarily engaged so as to facilitate efficient connection operation thereof. A lever 15 is pivotably attached to a side wall of the male connector housing 11. When a female connector housing 12 is inserted into the male connector housing 11, a cam receiving protrusion 17 of a cover 13 resiliently deforms lugs 15a of a lever 15 to be opened, so that the cam receiving portion may be advanced through a portion 23 into a cam groove 16. After such advancement, lugs 15a are returned to their original position by means of resilient deformation, so that the portion 23 is engaged with the cam receiving protrusion 17, so as to prevent dislodgement of the cam receiving protrusion. The thickness of the portion 23 of the cam groove is selected so as to prevent dislodgement of the cam receiving protrusion. A restricting protrusion 24 is protruded laterally from the cam receiving protrusion 17. The restricting protrusion serves to urge the lugs 15 downwardly, so as to maintain constant amount of engagement between the cam receiving protrusion 17 and the portion 23 of the cam groove. Another restricting protrusion 25 extending in a vertical direction may be provided in the side wall 1 of the male connector housing 11.

摘要： A connector includes lever pivotally mounted on a lateral wall of a male connector housing. When a female connector housing is inserted into the male connector housing, a cam follower projection formed on a cover is engaged with a cam groove formed on the lever. The lever is formed of four split pieces: a base plate, a second split piece, a third split piece, and an operating strip. For connecting or disconnecting the connectors, the lever can be expanded to maximize leverage. For storage, the lever can be contracted to minimize the amount of space occupied.

摘要： A retainer in its partial lock position sometimes moves to its full lock position upon being struck against something during transportation.
In a connector provided with a retainer 30 which can be held displaceably from a partial lock position to a full lock position with respect to a housing 10, an inadvertent movement of the retainer 30 from the partial lock position to the full lock position is prevented by providing a locking control member 34. Accordingly, the retainer 30 does not make such an inadvertent movement even if it is struck against something, e.g. during transportation.

摘要： PROBLEM TO BE SOLVED: To connect a fine wire securely to the wire connections of terminal metal fittings although increasing the plate thickness of the entire terminal metal fittings to some extent. SOLUTION: Terminal metal fittings 1 have wire connections 3 which can be assembled together in an overlapping fashion with their centers coincident and which can be turned in their assembled state and project generally radially outward from the center of assembly. The wire connections 3 are provided with a pair of pressure contact portions 12 which cut the sheath Wa of a wire W and make contact with an inner conductor Wb. This arrangement allows the pair of pressure contact portions 12 to cut the sheath Wa of the wire W and make contact with the inner conductor Wb, thus permitting a good connection even if the plate thickness of the entire terminal metal fittings 1 is increased to some extent and a fine wire W is to be connected.

摘要： PROBLEM TO BE SOLVED: To avoid a reversed mounting of an electric wire cover. SOLUTION: Rib 16, 24 are respectively formed on a top surface of an outer periphery of a housing 10 and on a bottom surface of an inner periphery of an electric wire cover 20. Two wiring spaces 36U, 36L along with both top and bottom surfaces of the housing 10 are provided between the housing 10 and the electric wire cover 20. When the electric wire cover 20 is in a normal state, the rib 16, 24 at the housing 10 side and the electric wire cover 20 side do not come in contact each other. If the electric wire cover 20 is in a reversed state, both ribs 16, 24 come in contact each other to control mounting of the electric wire cover 20.

摘要： PROBLEM TO BE SOLVED: To miniaturize a connector provided with a mechanism for preventing reverse rotation of a lock arm. SOLUTION: A lock arm 11 is formed in cantilever state on an upper face of a connector housing 10 and engaging projections 13 are formed in both right and left sides in the rear end part of the lock arm 11. Protective walls 14 are formed in both sides sandwiching the lock arm 11 and engaging holes 15A are formed in the rear end parts of the protective walls 14 and deformation of the lock arm 11 in the inverse direction to the bending direction of the lock arm is prevented by fitting the projections 13 in the holes 15A. In this way, since the lock arm 11 is prevented from being rotated reversely by fitting the projections 13 and the holes 15A, while being protected from interference with the projections 13, the protective walls 14 can be set as close as possible to the lock arm 11 and the gap of the protective walls 14 and the lock arm 11 is made narrow and thus the connector can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a connector divided in order to lower the fitting force and moreover for which fitting detection is made easy. SOLUTION: A female housing 2 is divided into a first housing 3 and a second housing 4 and successively fitted in rooms 1a, 1b of a male housing 1. A short circuit terminal 35 is installed only in the second housing 4 and interlocked with a lock arm 26 through a detection terminal 7a as to detect the fitting. A flexibly-deformable lock piece 16 is installed in the first housing 3 and in a half fitting state, the piece 16 is flexibly deformed and projected to the fitting region of the second housing 4 and in a regular fitting state, the piece 16 is restored and deformed to be locked by a locking part 23. In the case the first housing 3 is in an incomplete fitting state, the second housing 4 pushes the flexibly deformed lock piece 16 and squeezes the first housing 3 into the regular position. When the second housing 4 is fitted at the regular position, it is locked and the fitting is electrically detected.

摘要： PROBLEM TO BE SOLVED: To make the inserting of an electric wire into a cavity easy by the last one push. SOLUTION: A cover 40 is held on the outer surface of a housing 10 so as to be capable of rotating, and a pushing end 42 of the rear end of the cover 40 is turned and moved from the rear side to the front side within a cavity 11 of the housing 10 by the rotary motion of the cover 40. A terminal fitting 20 which stays in the semi-insertion state within the cavity 11 is pushed to the front normal position.
