摘要： A lever connector assembly has a stopping projection 35, which serves to hold a lever 30 in an initial position, and is located in such a position that it is distant from a trace described by a cam pin 12 as the cam pin 12 is inserted into a cam groove 34. When connectors 10 and 20 are in an initial fitting state, the cam pin 12 is inserted into the cam groove 34. Pivoting of the lever 30 results in a pressing member 13 engaging the stopping projection 35 and moving it outwards, to separate from the fitting groove 24. The amount of movement of the projection 35 is reduced compared with the prior art, and as a consequence frictional resistance to movement is lower.

摘要： This invention simplifies a process of attaching a torsion coil spring (6) to an arm (22) of a lever (21). Each arm (22) of the lever (21) is provided on its inner face with a ring slot (25) formed around a bearing hole (23) for accommodating a ring portion (6a) of the torsion coil spring (6) and a pair of holding slots (26 ) and (27) communicated with the ring slot (25) for accommodating end portions (6b) and (6c). A raised guide (29) is formed on the inner face of the arm (22) near an outer edge of the holding slot (27). The raised guide (29) has a ramp face (30) which continuously increases in height approaching the holding slot (27) and a precipices (33) contiguous to the outer edge of the slot (27). The arm (22) of the lever (21) may be provided on its inner face with a circular are tool slot (32) having a certain depth and extending from an end face of the arm (22) across a cam groove to the holding slot (27).

摘要： A lever connector that exhibits excellent space efficiency is provided. The lever connector includes female and male housings that are engageable with each other. A lever is mounted displaceably on the male housing and can be moved between an initial position and a fitting position. A cam groove is formed on the lever, and a cam follower is formed on the female housing. An entrance of the cam groove is aligned in a direction that intersects the fitting direction of the housings when the lever is at the initial position, and the female housing is assembled into a hood along the same direction.

摘要： A reinforcement rib is provided at a bottom connecting wall between a tab part and a main body part of a terminal fitting. The rear end of the rib extends slightly past the front end position of the main body part, and the front end of the rib is formed to extend to a position slightly forward of the rear end of the tab part. Also, the rib is formed to have a generally U-shaped cross-section. Accordingly, reinforcement of the boundary portion is possible, and even though a stress is concentrated on the boundary portion between the tab part and the main body part, the possibility of deformation can be reduced. Thus, male terminal fittings are provided in which deformation at the boundary portion of the tab part and the main body part rarely occurs.

摘要： A short circuit connector has male and female connector housings 10,20, one of which has a short circuit terminal 30 and the other of which has an insertion member 16. In the disconnected state the short circuit terminal 30 electrically connects two terminals of one housing, whilst in the connected state the short circuit terminal 30 is disengaged by the insertion member 16. The insertion member does not directly separate the contact area of the terminals. In a second aspect the connector includes a retainer 117 which has retention projections 124,127 engageable in the chamber of the short circuit terminal; separate engagement recesses are thereby avoided.

摘要： An engagement type connector assembly in which the arrangement of terminals is miniaturized. The connector assembly includes male and female connectors in which the female connector swings about a pair of supporting shafts provided at its end so as to be engaged with the male connector. The female connector includes a female housing and an outer frame. A pair of rotating shafts protrudes from the female housing in such a manner that the rotating shafts are in parallel with the supporting shafts so that the female housing is swingably coupled to the outer frame through the rotating shafts. That is, the female housing is supported through the rotating shaft on the outer frame. Hence, in engaging the female connector with the male connector by swinging the female connector, the female housing is allowed to swing independently of the outer frame, thus being correctly aligned with the male housing. Therefore, the inlets of the female terminals into which the male terminals are inserted may be made more compact. Additionally, the electrode spacing interval can be reduced commensurately because the female terminals engage the male terminals in a non-oblique or substantially straight manner.

摘要翻译： 一种接合型连接器组件，其中端子的布置小型化。 连接器组件包括阳连接器和阴连接器，阴连接器围绕设置在其端部处的一对支撑轴摆动，以便与阳连接器接合。 阴连接器包括阴壳体和外框架。 一对旋转轴以这样的方式从阴壳体突出，使得旋转轴与支撑轴平行，使得阴壳体通过旋转轴可摆动地联接到外框架。 也就是说，阴壳体通过外框架上的旋转轴被支撑。 因此，通过使阴连接器摆动来将母连接器与阳连接器接合，允许阴壳独立于外框架摆动，从而正确地与阳壳体对准。 因此，插入阳端子的阴端子的入口可以更紧凑。 此外，由于阴端子以非倾斜或基本上直的方式与阳端子接合，所以电极间隔间隔可以相应地减小。

摘要： A connector has a terminal insertion opening (23) and a restriction (25) projects in at an inner corner of the terminal insertion opening (23). A terminal fitting (30) has a rectangular tube (31) and a positioning projection (43) projects out from the rectangular tube (30). The positioning projection (43) is offset laterally from the restriction (25) when the terminal fitting (30) is oriented properly so that the tube (30) can be inserted into the terminal insertion opening (20). However, the positioning projection (43) is offset rotationally from the restriction (25) when the terminal fitting (30) is oriented improperly so that a corner (41) of the rectangular tube (31) contacts the restriction (25). The corner (41) of the rectangular tube (31) has a higher strength than a cantilevered projection from the rectangular tube (31). Thus, the corner (41) will not be deformed by contact with the restriction (25).

摘要： A bulb socket (S) has a main body (D) and a restricting projection (15) is formed continuously on an outer circumferential surface (18) of the main body (D) over the entire circumference. An O-ring (14) is fitted on the main body (D) behind the restricting projection (15). Thus, the restricting projection (15) contacts the O-ring (14) during detachment of a bulb socket (S), thereby separating the O-ring (14) from a sealing surface (16a) of an edge (16) of a mount hole (11). Further, the restricting projection (15) contacts a contact surface (16b) of the edge (16) during the mounting of the bulb socket (S), thereby preventing the bulb socket (S) from being pushed any further. This prevents the excessive squeezing of the O-ring (14) and prevents a reduction in its sealing function.
