Abstract: The invention provides a panel connector, permitted limited movement in an aperture while simultaneously preventing this connector from falling out. A female connector 20 is supported in a waiting state within a panel 10 by flanges 25 which make contact with edges of an attachment hole 11; contacting plates 52 of upper and lower pairs of resilient contacts 50, and for engagement with retaining members 12; and contacting plates 56 which engage supplementary retaining members 13. If an axis of a corresponding male connector 30 is misaligned relative to an axis of the female connector 20, some of the resilient contacts 50 bend, this causing the female connector 20 to move to align the axes of the two connectors 20 and 30. As the female connector 20 moves, the degree of engagement between some of the resilient contacts 50 is reduced.

Abstract: A housing (30) has a terminal accommodation part (32) for accommodating a terminal (20) and a circular arc wall (34) constituting an insertion opening (36) into which a socket (10) can be inserted. Slits (41) are formed on an upper end of the circular arc wall (34) to form elastic pieces (42). A protrusion (44) projects inwardly on each elastic piece (42) and is disposed to cover an upper portion of each contact piece (25) of the terminal (20). A guide surface (46) inclines inward on each protrusion (44). The lower end of the socket (10) slides on the guide surface (46) so that the socket (10) becomes almost coaxial with the insertion opening (36).

Abstract: A connector has female and male housings (10, 20) that are connectable with one another. A recess (28) is formed in an outer surface of the male housing (20). A detector (40) is mounted in an initial position in the recess (28) before the housings (10, 20) are connected, and is moved to a detecting position after the housings (10, 20) are connected properly for preventing separation of the housings (10, 20). The detector (40) has a disengaging hole (46), a rotation permitting space (47) that communicates with the disengaging hole (46) and a catchable portion (48) facing into the rotation permitting space (47). A disengaging jig (60) has a disengaging portion (62) that can be inserted into the disengagement hole (46), rotated and pulled against the catchable portion (48) to move the detecting member (40) to the initial position.

Abstract: Ribs (16) are formed on the outer surface of a female housing main body (13) such that the front ends thereof are retracted from the front end of the female housing main body (13). By setting this retracted distance (D) larger than a dimension (C) along depth of connection over which first guiding surfaces (26A) are formed, the ribs (16) enter guide grooves (25) after the female housing main body (13) is guided to substantially correct its disalignment. Thus, second guiding surfaces (26B) can be smaller, thereby making the opening edges of the guide grooves (25) smaller. This enables the miniaturization of a connector provided with the ribs (16) for the twisting connection preventing purpose.

Abstract: The invention provides a means of reducing the force required for fitting a lever connector. A connector 20 is divided into partitioned housings 22L and 22R. The timing of the fitting operation differs for each of the partitioned housings 22L and 22R, thereby causing the time at which peak fitting resistance occurs to differ. The peak fitting resistance being dispersed over the period between the beginning and the ending of the fitting operations of the two partitioned housings 22L and 22R. As a result, the overall peak value of the fitting resistance (the force required for the fitting operation) is reduced for the connector as a whole.

Abstract: A connector has means for preventing terminal fittings from being inserted in an inverted manner, and in which nothing protrudes from outer faces of these terminal fittings. Cut-away portions 17 are formed at a ceiling side of anterior ends of left and right side plates 11B of a box-shaped member 11 of a terminal fitting 10. Protrusions 34 are formed within a cavity 24 at anterior ends of left and right wall faces thereof, in locations somewhat removed from a wall face having a lance 26 formed thereon. These protrusions 34 are capable of fitting into the cut-away portions 17. When the terminal fitting 10 is correctly inserted, the protrusions 34 fit into the cut-away portions 17, and the terminal fitting 10 is pushed into a correct position and is retained by the lance 26. When the terminal fitting 10 is inserted in an inverted manner, the anterior end of the box-shaped member 11 strikes against the protrusions 34 before the terminal fitting 10 reaches the correct position.

Abstract: A lever-type connector simply and reliably shows whether male and female connector housings have been correctly fitted together. A posterior face of the female housing 16 has a cover 17. A lever 20 is provided with cam grooves 30 into which fit follower pins 32 of a male connector M and which is supported pivotably by axles 25 formed in the cover 17. The female housing 16 is correctly fitted within a hood 12 of a male housing 11 by pivoting the lever 20 from a start position to and end position. First ribs 40 are formed on the outer circumference of base ends 22 of arms 21 of the lever 20. Second ribs 45 are formed on left and right edges of a ceiling face 17A of the cover 17. When the lever 20 has been pivoted to the end position, these ribs 40 and 45 are aligned. Observing this alignment allows one to ascertain that the lever 20 is in the correct position.

Abstract: The present invention prevents a female connector that has been inserted in an inclined manner from interfering with male terminal fittings within a connector having long male terminal fittings provided in a central location within a hood. A cylindrical member 13 surrounding long male terminal fittings 12L protrudes from an inner side face 11 of the hood 10. Interferences between the long male terminal fittings 12L, and a comer Fb of a female connector F is prevented by appropriately determining the length to which the cylindrical member 13 will protrude. Interference between the female connector F and the long male terminal fittings 12 does not need to be taken into consideration in determining the protruding length of the hood 10. Consequently, the protruding length of the hood 10 can be relatively short.

Abstract: The invention permits a terminal retaining body provided with a retainer to fit smoothly into a cylindrical body. A male housing 10 is formed by fitting an inner housing 30, in which a retainer 40 is attached, into a hood 12 of an outer housing 11. A protruding member 60 protrudes outwards from a right side of the hood 12, and a guiding groove 61 is formed in a concave manner from an anterior end of an inner face of the protruding member 60. A guiding member 62, which forms an inwardly inclining face, joins with the posterior of the guiding groove 61. If the retainer 40 protrudes from a side face of the inner housing 30 when this inner housing 30 is being fitted, the guiding member 62 engages with the retainer 40 while the inner housing 30 is being pushed inwards, and automatically pushes the retainer 40 inwards.

Abstract: The invention provides a lever-type connector having simple and reliable means to show whether male and female connector housings have been correctly fitted together. A posterior face of a female housing 16 has a cover 17. A lever 20, which is provided with cam grooves 30 into which fit follower pins 32 of a male connector M, is supported pivotably by axles 25 formed in the cover 17. The female housing 16 is correctly fitted within a hood 12 of a male housing 11 by means of pivoting the lever 20 from a start position to an end position. First ribs 40 are formed on the outer circumference of base ends 22 of arms 21 of the lever 20. Second ribs 45 are formed on left and right side edges of a ceiling face 17A of the cover 17. When the lever 20 has been pivoted to the end position, these ribs 40 and 45 are aligned. Observing this alignment allows one to ascertain that the lever 20 is in the correct position.

Abstract: A connector in which the pivoting of a lever to a correct position can be used to detect whether male and female housings are in a fully fitted state. When a lever 30 is pivoted to a correct position, a stopping protrusion 40 fits with a lever stopping member 14 of a female housing 10, thereby causing the female housing 10 and a male housing 20 to fit completely together. When the lever 30 reaches the final position, releasing members 42 of the lever 30 push down arms 59 of a detecting member 50 attached in a groove 13 of the female housing 10, thereby releasing stopping members 60 of the arms 59 from an engaged state against regulating members 18 which protrude from side faces of the groove 13. As a result, the detecting member 50 can be pushed in an anterior direction. This movement of the detecting member 50 allows one to detect that the two housings 10 and 20 have been correctly fitted together.

Abstract: The present invention prevents a female connector that has been inserted in an inclined manner from interfering with male terminal fittings within a connector having long male terminal fittings provided in a central location within a hood.

Abstract: A detecting protrusion 42 of an electrical terminal is formed by cutting out a posterior portion of an opposing face 39 of main body 31, this detecting protrusion 42 protruding upwards. If a terminal fitting 30 to be inserted into a cavity 11 is only half-inserted, when a retainer 20 is pressed towards a main stopping position, a lower face 24 of a stopping member 21 strikes against an upper face 44 of the detecting protrusion 42, thereby preventing the retainer 20 from being pressed in. As a result, the half-insertion of the terminal fitting 30 can be detected. The retainer 20 is in a more shallowly inserted state compared to the case where movement of the retainer 20 is prevented by the lower face 24 of the stopping protrusion 21 striking against the opposing face 39, the amount of protrusion of the retainer 20 being determined by the height of the detecting protrusion 42.

Abstract: A multilevel connector is provided for securely engaging male and female connector housings. The connector 1 includes a main block 4 integrally formed with a receptacle 3, an auxiliary block 5 to be assembled with the main block 4 and a lid 6 to be assembled so as to cover the auxiliary block 5. Terminal cavities 2A are arranged side by side in each of the main and auxiliary blocks 4, 5.

Abstract: The present invention relates to a connector equipped with a retainer that prevents a terminal that has been inserted into a connector housing from disengaging. To prevent the unexpected movement of the retainer to the fully engaged position and to be able to detect whether the retainer is fully engaged, the outer faces of the retainer do not extend above the outer faces of the connector housing when the retainer is in a partially engaged position. Thus, the retainers are not pushed into a fully engaged position by other members. Moreover, because the projections that extend above the connector housings are placed on the outer face of the retainers, the projections seldom interfere with other elements. When the connector housings are coupled with the receiving parts of the frame in a partially engaged position, the projections interfere with the open edges of the receiving parts and thus prevent the connector from achieving the fully engaged position.

Abstract: Male sub-connectors 3 are accommodated in apertures 2 formed in a male frame 1, and female sub-connectors 23 are accommodated in apertures 22 formed in a female frame 21. A guide wall 15, on the inside of which the female frame 21 fits closely, is provided around the entire periphery of the top surface of the male frame 1. The female frame 21 is temporarily assembled with hooks 56, which engage longitudinal grooves 57 in the guide wall 15. When a lever 40 is operated so as to draw the male and female frame together, the guide wall 15 ensures the connectors themselves are relieved of lateral loads. In an alternative embodiment a similar arrangement is provided between one pair of connectors tightly engaged in the respective frames.
