Abstract: A female terminal includes a resilient contact piece portion extending rearwardly from a front end edge of a bottom wall of a mating terminal-inserting portion of a tubular shape, and a free end portion of the resilient contact piece portion can slide over the bottom wall. A convex portion is formed at the free end portion of the resilient contact piece portion, and projects toward the bottom wall, and when the resilient contact piece portion is resiliently deformed upon insertion of a male terminal, the convex portion is brought into contact with the bottom wall, so that that portion of the resilient contact piece portion, extending forwardly from that portion of the convex portion contacted with the bottom wall, is spaced from the bottom wall by the convex portion.

Abstract: A joint connector includes housings which can be stacked together, with a predetermined gap formed therebetween, each of the housings having a plurality of juxtaposed terminals received therein, and a circuit forming element which is inserted into the gap between the stacked housings, and connects arbitrarily-selected ones of the terminals in the adjacent housings, adjoining to each other in a stacking direction, and also connects arbitrarily-selected ones of the terminals in the same housing. By inserting the circuit forming element, the connection of the terminals can be effected easily, and besides a desired circuit can be easily obtained by the circuit structure of the circuit forming element.

Abstract: A connector (1) includes terminals (3), and a connector housing (2) having terminal receiving chambers (4). The terminal (3) has resilient curl portions (32, 32) of a generally mountain-like cross-sectional shape which are integrally formed respectively on opposite side edges of a base plate portion (31). A lance (5) is formed within the terminal receiving chamber (4), and two projections (23, 23) are formed integrally on the lance (5), and project in a direction of a width of the terminal receiving chamber (4) which direction is perpendicular to a direction (see P, in FIG. 7) of insertion of the terminal (3), and the two projections can be brought into sliding contact with apexes (41, 41) of the resilient curl portions (32, 32), respectively.

Abstract: A bus bar is constituted by integrally forming pairs of terminal contact pieces, each pair of which is in contact with an opposed terminal, a pair of connecting base portions, which integrally connect the base-side portions of the terminal contact pieces arranged on the same side thereof, and connecting pieces for connecting the pair of connecting base portions. This bus bar is integrally coupled to a bus bar fixing member constituted by an insulating member. An arbitrary circuit including so-called a skip connection can be constructed by suitably cutting the connecting base portions and the connecting piece. Thus, the entire circuit forming element is constituted as one component.

Abstract: At least one positioning projection (12, 13, 14, 15, 16 or 17) is formed at least on at least one deformed wall (e.g., 2) of a synthetic resin-made connector housing (1). The projecting height of the at least one positioning projection (12, 13, 14, 15, 16 or 17) is defined so as to correct an amount of deformation of the at least one wall (2, 3, 4 or 5), and positioning is effected by using the at least one positioning projection (12, 13, 14, 15, 16 or 17) as a reference. In case of a plurality of the positioning projections (12 to 17), the plurality of the positioning projections (12 to 17) are juxtaposed at least on the at least one wall (2, 3, 4 or 5), and projecting height of the plurality of positioning projections (12 to 17) are varied in correspondence with a shape of deformation of the at least one wall (2, 3, 4 or 5).

The connector housing (22) has at least one connection port (33) through which a mating terminal is insertable, a detection-pin inserting port (34) through which a lance-displacement detecting pin of a connector conduction-test tool is insertable, and a contact-pin inserting port (35) through which a conduction contact pin (24) of the connector conduction-test tool is insertable. The contact-pin inserting port 35 is formed in such a manner as to cut away an edge portion of the connection port (33).

Abstract: In a connector fitting construction of the invention, a slider 60 is slidably supported within a housing 53 of a female connector 50 housing, and when the female connector is to be fitted relative to a male connector 70, the slider cooperates with compression springs 59 to flex a lock arm 56 so as to retainingly engage the lock arm with the male connector 70. A pair of abutment projections 64 are formed respectively at opposite side portions of a lower surface of a slider arm 62 provided at the slider 60. A pair of stopper projections 72 are formed on an upper surface of a housing 71 of the male connector 70, and are pressed respectively against the abutment projections 64 during a connector fitting operation to move the slider 60 toward a rear end of the female connector 50. An abutment surface 72a of a generally trapezoidal shape is formed on a front surface of each of the stopper projections 72.

Abstract: The present invention provides a machine tool which is adapted to discharge chips brought into the work area from the machining area outside the machine tool by a simpler operation. The machine tool (1) comprises a bed (51), a column (52), a spindle head (53), a table (54), a pallet base (63) and a pallet changer (11), wherein the spindle head (53) and the table (54) are movable relative to each other along three orthogonal axes. In the machine tool (1), a chip conveyor (10) having a transport path located below a machining area (A) and a work area (B) is provided for conveying chips. Thus, chips generated in the machining area (A) and chips brought into the work area (B) from the machining area (A) are collected on the chip conveyor (10), and conveyed and discharged outside the machine tool (1) by the chip conveyor (10).

Abstract: The inspection unit has an engagement structure of a resilient locking finger and a finger deflection inspecting pin. The locking finger is provided in a terminal accommodation chamber defined in a connector housing for locking a terminal received in the terminal accommodation chamber. The finger deflection inspecting pin is provided in the inspection unit for inspecting an incomplete insertion state of the terminal. The finger deflection inspecting pin has a forward end portion formed with a concave surface. The locking finger has an extended forward end with a round head. When the extended forward end portion is received in and abuts against the concave surface, the extended forward end portion is guided by the concave surface due to the engagement structure. The concave surface may have a U-shaped section.
