Abstract: In a side plate (52) of a retainer (50), a jig insertion groove (70) is cut at an upper end portion of its front edge. A releasing jig (J) is insertable into a gap between the bottom surface of the jig insertion groove (70) and a vertical front edge of a recessed surface (27) of a female housing (20). If the releasing jig (J) is rotated so as to be pried, the retainer (50) is pushed back diagonally downward along a guide groove (60) and reaches a temporary retaining position.

Abstract: A housing (10) of a connector has vertical screw holes (14) parallel to a connecting direction of the housing (10) and horizontal screw holes (19) normal to the connecting direction. Thus, the housing (10) is both horizontally and vertically mountable on a circuit board (P), and flexibility in the use of the housing (10) is improved. Further, the horizontal screw holes (19) are normal to the connecting direction and can be formed by a pair of molds movable along the connecting direction. Therefore, costs necessary for the molds can be reduced.

Abstract: A terminal fitting (10) has a sidewall (14) and a stabilizer (30) is provided at the sidewall (14) for interfering with the entrance of a cavity (42) when the terminal fitting (10) upside down. The terminal fitting (10) has a posture-holding portion (35) at a sidewall (15) facing the stabilizer (30). The posture holding portion (35) contacts the inner wall of the cavity (42) if the terminal fitting (10) is mounted in a wrong posture. Thus, the terminal fitting (10) will not incline in the cavity (42). Accordingly a sufficient amount of interference of the stabilizer (30) with the edge is ensured, and erroneous insertion of the terminal fitting (10) is prevented.

Abstract: A connector has a housing (20) and a retainer (40) for locking terminal fittings in the housing (20). The retainer (40) has a main body (41) with locking sections (45) engageable with the terminal fittings when the retainer (40) is at a full locking position in the housing (20). Side plates (42) are provided at opposite lateral sides of the main body (41) for covering stepped outer side surfaces (29) of the housing (20). A locking claw (53) is provided at an upper end (42a) of each side plate (42) for engaging a holding portion (33) on the stepped surface (29). The retainer (40) can be held at the full locking position by engagement of the locking claws (53) and the holding portions (33). The housing (20) has protecting portions (35) that cover the upper ends (42a) of the side plates (42) from outer sides when the retainer (40) is at the full locking position.

Abstract: A connector has a housing (10) with a cavity (11) and a resiliently deformable lock (13) for locking a female terminal fitting (30) in the cavity (11). The lock (13) has a base (25) and a projection (26) that projects into the cavity (11) from the base (25). Both side surfaces (25b) of the base (25) are formed by a mold that is moved forward to open, and notches (17a) are formed in the front surface of the female housing (10) by this mold. The notches (17a) extend more outward than inner side surfaces (11b) of the cavity (11) with respect to the widthwise direction. Both side surfaces (26c) of the projection (26) are formed by a mold moved backward to open. The projection (26) is narrower than the base (25).

Abstract: A female housing (10) has cavities (11) into which female terminal fittings (30) are insertable from behind. A lock (13) projects forward from its base end and is restorable after being temporarily resiliently deformed by the female terminal fitting (30) being inserted, thereby engaging and locking the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) maneuverable by a disengagement jig (60) from front are provided at positions on the front surface of each lock (13) retracted from the locked terminal fitting (30) and within a width range of a locking surface of the lock (13) engageable with the terminal fitting (30) and located more toward the base end of the locking portion than the locking surface.

Abstract: A joint connector (JC) has a housing (30). Fitting recesses (33, 38A, 38B, 38C) are formed in opposite sides of the housing (30) for receiving a power-supply side connector (10) and electric-part side connectors (20). A ground terminal (50) has a row of tabs (55A) projecting from an edge of a busbar (51) and has a grounding plate (52) at an end of the busbar (51). The ground terminal (50) is mounted at a lower level of an intermediate wall (40) of the housing (30) by insert molding, so that the tabs (55A) are in the electric-part side fitting recesses (38A, 38B, 38C). Joint terminals (60A to 60D) have tabs (55B) projecting from opposite lateral edges of a busbar (51) and are mounted at upper and middle levels of the intermediate wall (40) by pressing so that the tabs (55B) are in the fitting recesses (33, 38A, 38B, 38C).

Abstract: A joint connector (JC) has a ground terminal (50) mounted in a housing (30) so that a grounding plate (52) projects outside. The grounding plate (52) is fastened to a metal panel (80) by a nut (83) and bolt (87). A mount hole (85) of rectangular cross section is formed at a specified distance in a specified direction from the nut (83). A clip (70) is formed on the bottom of the housing (30) so that the positional relationship of the clip (70) and an insertion hole (53) of the grounding plate (52) corresponds to that of the mount hole (85) of the nut (83) of the metal panel (80). The housing (30) is mounted on the metal panel (80) by inserting the clip (70) into the mount hole (85). Thus, the insertion hole (53) of the grounding plate (52) is at a position aligned with the nut (83).

Abstract: A joint connector (40) is composed of a joint terminal (50) and a relay housing (41). A first housing (10) and a second housing (20) are mounted on an electric part-side connector connection portion (42) of the relay housing (41). A power-source side housing (30) is mounted on a power-source side connector connection portion (46). Terminal fittings are short-circuited with the joint terminal (50). The first housing (10) and the second housing (20) share the power-source side housing (30) and the joint connector (40).

Abstract: A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.

Abstract: A terminal fitting (10) is made of a metallic plate material stamped out into a specified shape and has a substantially flat main body (13), a substantially flat coupling (16) extending from an outer peripheral edge of the main body (13), and a wire crimping portion (17) further extending from an extending end of the coupling (16). The coupling (16) of the terminal fitting (10) has a reinforcement formed by placing reinforcing plates (20, 26) substantially one over the other.

Abstract: Auxiliary connectors (6) of a female connector (1) are formed for a plurality of types of female terminal fittings (8). When a plurality of auxiliary connectors (6) of the same type are mounted into a frame (2), the number of the terminal fittings to be inserted into the individual auxiliary connector (6) is decided based on connection loads per terminal fitting to ensure that an operation load of the auxiliary connector (6) does not exceed an upper-limit value, and the same number of terminal chambers (7) as the decided number of the terminal fittings are formed in the auxiliary connector (6). Thus, regardless of the specifications of the female terminal fittings (8), the female terminal fittings (8) can be mounted into all the terminal chambers 7 without exceeding the upper-limit value of the operation load of the auxiliary connectors (6).

Abstract: A connector has a housing (10) with a cavity (11) and a resiliently deformable lock (13) in the cavity (11). The connector further has a terminal fitting (30) that can be inserted into the cavity (11). The insertion of the terminal fitting (30) deforms the lock (13). However, the lock (13) restores when the terminal fitting (30) is inserted completely, and locks the terminal fitting in the cavity (11). The terminal fitting (30) and the cavity (11) are formed with mutually engageable structures (53, 26) for preventing inclination of the terminal fitting (30) in the deforming direction of the lock (13).

Abstract: A female housing (10) has cavities (11) into which female terminal fittings (30) are insertable from behind. A lock (13) projects forward from its base end and is restorable after being temporarily resiliently deformed by the female terminal fitting (30) being inserted, thereby engaging and locking the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) maneuverable by a disengagement jig (60) from front are provided at positions on the front surface of each lock (13) retracted from the locked terminal fitting (30) and within a width range of a locking surface of the lock (13) engageable with the terminal fitting (30) and located more toward the base end of the locking portion than the locking surface.

Abstract: A male connector (M) has male housings (20A, 20B, 20C) and is connectable with a female connector (F) with female housings (40A, 40B, 40C). Error connection preventing projections (28A, 28B) of the male housings (20A, 20B) are received in receiving portions (47A, 47B) of the female housings (40A, 40B) to connect the two connectors (M, F) properly if the combination of the housings in the male and female connectors (M, F) is correct. However, the error connection preventing projections (28A, 28B) on the male housings (20A, 20B) interfere with opposed the female housings (40B, 40C) and hinder connection of the two connectors (M, F) if the combination of housings is incorrect.

Abstract: A housing (10) of a connector has vertical screw holes (14) parallel to a connecting direction of the housing (10) and horizontal screw holes (19) normal to the connecting direction. Thus, the housing (10) is both horizontally and vertically mountable on a circuit board (P), and flexibility in the use of the housing (10) is improved. Further, the horizontal screw holes (19) are normal to the connecting direction and can be formed by a pair of molds movable along the connecting direction. Therefore, costs necessary for the molds can be reduced.

Abstract: A female division connector F includes a female-side frame 10, having a receiving chamber 11, and a plurality of female housings 20 fitted in the receiving chamber 11. These female housings 20 are suitably selected from a sub-connector housing group including a plurality of kinds of housings having different outer dimensions. Each of the female housings 20 has cavities 21 arranged at a predetermined pitch d. Lock projections 24 are formed respectively at those portions of an outer surface of the female housing 20 corresponding respectively to the cavities 21. Juxtaposed guide grooves 15 are formed in an inner wall surface of the receiving chamber 11, and the lock projections 24 are fitted in the guide grooves, thereby positioning the female housing 20.

Abstract: A connector has a housing (10) with cavities (11) into which terminal fittings (30) are insertable. Locks (13) in the housing (10) deform during insertion of the terminal fittings (30) into the cavities (11), but then resiliently restore to lock the terminal fittings (30) in the cavities (11). Lowered portions (12a) of a bottom wall (12) of the housing (10) face the locks (12) and prevent the locks (13) from being excessively deformed. The bottom surface of each lock (13) has a convex arcuate surface (13c) and each lowered portion (12a) of the bottom wall (12) has a recess (12b) substantially conforming to the convex arcuate surface (13c) to accommodate the convex arcuate surface (13c) when the lock (13) deforms.

Abstract: A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.

Abstract: A connector has a housing (20; 60) and a rubber plug (30; 70) mounted to the housing (20; 60). A plug holder (40; 80) can be held at a partial locking position on the housing (20; 60) where it is spaced back from the rubber plug (30; 70) and can be moved to a full locking position where it is located immediately behind the rubber plug (30; 70). The plug holder (40; 80) is dimensioned and configured to correct the orientation of the terminal fittings (10) when the plug holder (40; 80) is at the partial locking position. Thus, terminal fittings (10) can be inserted into the housing (20; 60) without damaging the rubber plug (30; 70).
