Abstract: A board connector includes terminal fittings (60) including board connecting portions (62), and a housing (10) made of synthetic resin containing a fibrous filler (80), disposed on a circuit board (90) and including a wall (18) rising in a vertical direction intersecting a surface of the circuit board (90). The wall (18) has a terminal mounting region (21) in which the terminal fittings (60) are mounted. The wall (18) includes elongated recesses (31) with a longitudinal direction aligned with the vertical direction and arranged side by side in a width direction in a distant region (22) located on a side of the terminal mounting region (21) distant from the circuit board (90).

Abstract: A housing (12) of a board connector (10) to be connected to a circuit board (P) is disposed such that a connection surface to a mating connector (50) is exposed to outside through an opening (41) of a case (40) capable of accommodating the circuit board (P) inside. The housing (12) includes outer locking protrusions (31) for locking a peripheral edge part of the opening (41) of the case (40) from outside of the case (40) so that the board connector (10) will not displace into the case (40) due to forces exerted by a mating connector (50) during a connection operation.

Abstract: A board connector (10) has a tubular housing (20) that includes a back wall (25) with penetrating through holes (26). A terminal fitting (60) includes a tab (61) to be arranged to project into the housing (20) through the through hole (26), a press-fit portion (62) to be arranged inside the through hole (26) and a lead portion (63) to be arranged along a surface of a board (90). The press-fit portion (62) is inserted into the through hole (26) with an overlapping margin in a cross-section along a height direction in which the lead portion (63) faces the surface of the board (90). The tab (61) is inserted into the through hole (26) without any overlapping margin in the same cross-section.

Abstract: A retainer (10) is formed from a body (18) and extended portions (11). The body (18) includes two deflectable legs (20) and the legs (20) include locking claws (21) to be held onto a male connector housing (1) at a partial locking position and locking protrusions (22) to be locked to the male terminal fittings (5).

Two inwardly deflectable locking arms (56) are formed on a detector (39) and locked to the first or second lock receiving portions (43, 44) to restrict a backward movement when the detector (39) is at an initial position and a detecting position. The locking arms (56) are arranged utilizing dead spaces behind the lock-arm protection walls (37).

A pressure receiving surface (15) is formed on the housing (11) and is configured to restrict a movement of the retainer (30) toward the full locking position by pressing the retainer (30) in directions intersecting a moving direction of the retainer (30) from the partial locking position to the full locking position when the retainer (30) is at the partial locking position.

Abstract: A connector (A) is provided with a housing (10) made of synthetic resin, press-fit holes (13) formed through the housing (10) and each having a substantially rectangular cross-sectional shape, and terminal fittings (20) to be inserted into the press-fit holes (13). Each terminal fitting (20) has a first press-fit portion (25) with a substantially rectangular cross-section and brings two substantially parallel flat areas (26) into surface contact with the inner wall of the press-fit hole (13) in a fluid- or liquid-tight manner. The first press-fit portion (25) has first and second bulges (27A, 27B) that locally bulge in forward and backward directions parallel to the two flat areas over the entire areas in a width direction connecting the two flat areas (26) and press the inner wall of the press-fit hole (13) in a fluid- or liquid-tight manner.

Abstract: An air hole (29) is formed to penetrate through a back wall (23) of a receptacle (22). Leading end portions (61) of male terminal fittings (60) are inserted into an inner portion (28) of a tube (27) and the air hole (29) communicates with the inner portion (28). If a female connector is connected in a posture inclined from a proper connecting posture, the tube (27) interferes with the female connector to prevent any further connecting operation. The tube (27) surrounds a plurality of male terminal fittings (60) together. A wall (31) for partially closing openings of the inner portion (28) is formed at a leading end portion of the tube (27).
