Abstract: In terminals of an FFC (10), an upper-side insulation sheet (12) is torn off in a predetermined range to expose an upper side of conductive paths (11) and leave conductive path-disposing portions of the FFC (10) in the shape of the teeth of a comb to form connection regions (14). A terminal fitting (20) has a bottom plate (22) and a ceiling plate (23) both extended rearward from a connection part (21), such that the ceiling plate (23) can be opened and closed. Each of the connection regions (14) is pressed and sandwiched between the bottom plate (22) and the ceiling plate (23). A crimping piece (29) of the bottom plate (22) is crimped to a side edge of the ceiling plate (23), with the connection region (14) held in the crimping piece (29). The entire terminal fittings (20) are accommodated in cavities (41) of a connector housing (40) respectively, with the connection regions (14) connected to the terminal fittings (20) respectively.

Abstract: A conductive path (11) is exposed on an upper surface of an FFC (10). At the rear end of the terminal fitting (20), a wavy bottom plate (22) and a wavy ceiling plate (23) confront each other such that the ceiling plate (23) can be opened and closed relative to the bottom plate (22). A piercing piece (35) whose front end is sharp is formed at the rear end of the ceiling plate (23) in about the half of the entire width of the rear end thereof by bending the piercing piece (35) perpendicularly. The terminal of the FFC 10 is sandwiched between the bottom plate (22) and the ceiling plate (23), and both crimping blades (26) are crimped to side edges of the ceiling plate (23). As a result, the conductive path (11) is bent wavily, the ceiling plate (23) contacts the conductive path (11), and the piercing piece (35) is pierced into the conductive path (11) and projects from the lower surface thereof. The FFC (10) is sandwiched the bottom plate (22) and the ceiling plate (23).

Abstract: Terminal hardware for a flat-type conductor is provided which can provide a high contact pressure between the terminal hardware and the conductor and a superior holding force against a tension tending to separate the terminal hardware from the conductor. At a terminal end of the flat-type conductor, the conductor is exposed on an upper surface. A base plate is formed to extend from a rear end of the terminal hardware, and a top plate is provided so as to face the base plate and be capable of being opened and closed. Two pairs of crimping portions are provided forwardly and rearwardly on the base plate in a longitudinal direction of the base plate. Further, both the base plate and the top plate have undulating-portions, respectively. A front flat portion is provided on the top plate with an elongated projection extending in a longitudinal direction of the top plate and a rear flat portion is also provided on the top plate with a cut-in projection.

Abstract: A connector (A) includes a connector housing (10) with a locking arm (11) extending from an outer surface (10A) of the connector housing (10). A groove (16) is formed on a base part (12) of the locking arm (11) along a direction in which the base part (12) is erected. A groove (18) is formed on an arm part (13) of the locking arm (11) along a direction in which the arm part (13) extends. A thickness Tk between a bottom surface (16A) of the groove (16) of the base part (12) and a rear surface (12R) thereof is set larger than a vertical thickness Ta of the arm part (13). When the locking arm tilts in a direction in which the locking arm (11) moves away from the connector housing (10), with the base part (12) acting as the supporting point of the tilting motion of the locking arm (11), a rib-shaped portion (16B) at both sides of the groove (16) makes the base part (12) less flexible than the arm part (13). Thus, the degree of the strain of the base part (12) is low.

Abstract: An insulation-displacement terminal has opposed side walls (12) and a wire-receiving space therebetween. V-shaped insulation-displacement portions (16) are formed by a pair of plates (16F, 16R) that are bent from the side walls (12) and project into the wire-receiving space. A bending angle (&bgr;) between one plate (16R) and the side wall (12) is larger than a bending angle (&agr;) between the other plate (16F) and the side wall (12). A pulling force on the wire (W) does not make a loose movement since the bending angle of the plate (16F) located at the side behind with respect to a pulling direction is a right angle. Further, since the bending angle (&agr;) between the plate (16R) and the side wall 12 is larger, an angle (&ggr;) between the plates (16F) and (16R) of the insulation-displacement portion (16) is sufficiently large to ensure a wide contact area with a core (Wb) of the wire (W). Thus, a high contact reliability can be secured.

Abstract: An insulation-displacement terminal fitting (10) has cutting blades (20) formed by making cuts in side walls (22) of the insulation-displacement terminal fitting (10) and bending cut portions at right angles to face each other and to define a press groove (24) therebetween. The press groove (24) is defined by contact edges (25) that are spaced apart by a distance that is slightly smaller width than the diameter of a core (Wa) of the coated wire (W). Step edges (26) extend outwardly from the contact edges (25) at right angles to the side walls (22). Guide edges (27) extend up from the step edges (26). The distance between the guide edges (27) is greater than the distance between the edges (25). Cuts are made in a coating (Wb) by pressing the coated wire (W) against the right-angled step edges (26). The exposed core (Wa) then can be held between the opposite contact edges (25).

Abstract: An insulation-displacement terminal fitting (T) includes a pair of insulation-displacement portions (15) that project inwardly substantially in V-shape from side walls (12) to be connected with a wire (W) by insulation displacement. The side walls (12) are formed with substantially I-shaped locks (17) that project in positions spaced from the insulation-displacement portions (15) along the longitudinal direction of the wire (W) and can bite in a resin coating (Wa). An external force may try to move the wire (W) along its longitudinal direction acts. However, the locks (17) catch the resin coating (Wa) to restrict a loose movement of the wire (W).

Abstract: A connector has opposed side walls (12) with a wire-receiving space therebetween. Insulation displacement portions (17) are cantilevered from the side walls (12) by cutting portions of the side walls (12) and bending the cut portions into the wire-receiving space. Bent portions (17A) are formed by bending free ends (17B) of the insulation-displacement portions (17) back toward the respective side wall (12).

Abstract: A connector (A) has a connector housing (10) with an outer surface (10A). A locking arm (11) extends from the outer surface (10A). A groove (16) is formed on a base part (12) of the locking arm (11) along a direction in which the base part (12) is erected. A groove (18) is formed on an arm part (13) of the locking arm (11) along a direction in which the arm part (13) extends. The sectional configuration of the grooves (16, 18) include concave quadrantal curved surface (16R, 18R) that are smoothly continuous with each other. The formation of the grooves (16), (18) allow a stress to be dispersed to the entire locking arm (11). Thus, it is possible to reduce the strain to be applied to the base part (12) and prevent breakage of the base part (12).

Abstract: A terminal fitting (20) is provided for an FFC (10). The FFC (10) includes a conductive path (11) that has upper and lower surfaces covered with an insulation sheet (12). The terminal fitting (20) includes bottom plate (22) with contact blades (25) erected on both side edges of the bottom plate (22). A ceiling plate (23) confronts the bottom plate (22) and can penetrate into the space between the opposed contact blades (25). When the ceiling plate (23) is closed, it moves downward, with both side surfaces thereof in sliding contact with an inner surface of each contact blade (25), while the ceiling plate (23) presses the terminal of the FFC (10) toward the bottom plate (22). Consequently, the contact blades (25) pierce through the terminal of the FFC (10). The contact blades (25) pierce into the conductive path (11) and the ceiling plate (23) prevents floating of the FFC (10).

Abstract: An insulation-displacement terminal fitting (10) has plate-shaped blades (27) disposed before V-shaped contact portions (23) along a wire-insertion direction. The blades (27) make cuts (C) in an insulation coating (Wb) of a wire (W). The insulation coating (Wb) then is cut open by the V-shaped contact portions (23). A cut-open piece (Wc) of the insulation coating (Wb) that is caught by the contact portions (23) is not forcibly stretched. Thus, a core (Wa) is not pulled in a direction to be withdrawn from a clearance between the contact portions (23). An accommodation space (30) in which the caught cut-open piece (Wc) of the insulation coating (Wb) is accommodated is located within a height range of side walls (21). Thus, the cut-open piece (Wc) of the insulation coating (Wb) does not project above the side walls (21).

Abstract: Terminal hardware for a flat-type conductor is provided which can provide a high contact pressure between the terminal hardware and the conductor and a superior holding power against a tension tending to separate the terminal hardware from the conductor. At a terminal end of the flat-type conductor, the conductor is exposed on an upper surface. A base plate is formed to extend from a rear end of the terminal hardware, and a top plate is provided so as to face the base plate and be capable of being opened and closed. A pair of crimping portions are provided at opposite side edges of a rear end of the base plate. Further, both the base plate and the top plate have undulating portions, respectively. The terminal end of the flat-type conductor is inserted between the base plate and the top plate. The pair of crimping portions pierces the insulation sheet of the flat-type conductor from one side toward the other.

Abstract: An electrical connector A has a connector housing (10) with a locking arm (11) formed integrally with an outer surface of the connector housing(11). A thickness Tk of a base part (12) of the locking arm (11) is set larger than a thickness Ta of an arm part (13) thereof. Thus, the flexure rigidity of the base part (12) is greater than that of the arm part (13). When the locking arm (11) tilts in away from the connector housing (10), with the base part (12) acting as the supporting point of the tilting motion of the locking arm (11), the degree of the strain of the base part (12) is low. This is because the base part (12) is less flexible than the arm part (13). A force of tilting the locking arm (11) is relaxed by elastic deformation of the arm part (13), which is more flexible than the base part (12). A stress generated by the tilting of the locking arm (11) does not concentrate on the base part (12), but is dispersed in the arm part (13). Thus, it is possible to prevent the base part (12) from being broken.

Abstract: A terminal fitting (20) has a base plate (22) and a pressing plate (30) confronting the base plate (22). A side wall (23) is formed on one side edge of the base plate (22). A contact blade (25A) is projected on an upper edge (23A) of the side wall (23) such that the contact blade (25A) is widthwise flush with the side wall (23). A contact blade (25B) is erected on the other side edge of the base plate (22) such that the contact blade (25A) and the contact blade (25B) have the same height. On the bottom portion of the base plate (22), a raised part (27) is formed for a disposing position of each contact blade (25A) by folding the other side edge of the base plate (22). The height of the upper surface of the raised part (27) is a little larger than that of the upper edge (23A) of the side wall (23).
