Abstract: In a terminal of an FFC (10), upper and lower surfaces of a conductive path (11) are covered with an insulation sheet (12). A terminal fitting (20) for the FFC (10) includes a base plate (22) extended from the rear end of a terminal fitting (20). Contact blades (25) are erected on both side edges of the base plate (22). A pressing plate (23) that can be opened and closed confronts the base plate (22).

Abstract: An insulation-displacement terminal fitting is provided to prevent cracks and/or splits during the formation of V-shaped blades in the side walls (11A) of the insulation-displacement terminal fitting. To achieve this objective, slits (15) are formed along boundaries between a bottom wall (13) and side walls (11A) at least in the forming range of the blades (11B), and a bent portion (16) is formed in the bottom wall (13) in the area of the slits (15). The blades (11B) in the side walls (11A) and the bent portion (16) in the bottom wall (13) are formed substantially simultaneously. Thus, neither the blades (11B) nor the side walls (11A) undergo an extensional deformation since base ends (11Ba) of the blades (11B) are brought closer to each other in the side walls (11A) and base ends (16a) of the bent portion (16) are brought closer to each other in the bottom wall (13).

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 Thus, a core (Wa) is not pulled in a direction to be withdrawn from a clearance between the contact portions (23).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: An insulation-displacement terminal includes blades (12) that project inwardly from opposed side walls (14). Each blade (12) has V-shaped edges (12A) and a contact edge (12B). The V-shaped edges (12A) are inclined to guide wire a (W) from the side walls (14) toward the contact edges (12B) when viewed in the longitudinal direction of the wire (W). A hook (15) is formed at an end of each V-shaped edge (12A) toward the corresponding contact edge (12B). Thus, even if an angle of inclination of the V-shaped edges (12A) with respect to a wire pushing direction is made smaller, the resin coating (Wa) of the wire (W) can be securely cut open by the hooks (15).

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: An insulation displacement contact terminal has a bottom plate, a pair of side plates, a pair of contact plates, and projecting portions. The side plates respectively extend from both side edges of the bottom plate and oppose each other. The contact plates are respectively partly bent from the side plates and oppose each other. Between the contact plates and the bottom plate are formed gaps. The gaps permit the contact plates to be moved in the direction of their being moved toward each other. Mutually opposing edges of the contact plates define a slot for receiving a clad electric wire therein. The clad electric wire has a core wire and a clothing portion that clothes the core wire. The width of the slot decreases with the movement of the contact plates. With the press insertion of the clad electric wire into the slot, the edges cut into the clothing portions and contact with the core wire. The projecting portions respectively project from the contact plates.

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 (&bgr;) 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.

The wire press-connecting portion (3) includes a thick bottom plate portion, thick side plate portions (12) extending upwardly from opposite side edges of the bottom plate portion, and thick press-connecting piece portions (17, 18) projecting inwardly from edges of window portions (16) formed through the side plate portions (12).

Abstract: An insulation-displacement terminal (T) includes opposed side walls (12) and a wire-receiving space therebetween. Insulation-displacement portions (17) project from the side walls (12) and into the wire-receiving space. Each insulation-displacement portion (17) has two bases (18) that project from longitudinally spaced positions on the corresponding side wall (12). A blade (19) has two panels folded from the respective bases (18) and projecting further into the wire-receiving space. The folded blades (19) cut sharply into the resin coating (Wa) of a wire (W) urged into the wire-receiving space, and the bases (19) resist pulling forces on the wire (W). Therefore, a loose movement of the wire (W) in its longitudinal direction can be prevented.

Abstract: An insulation displacement terminal fitting has V-shaped blade portions (17) each of which is formed by two blades (19) that interest at contacting edges (20). V-shaped cutting edges (21) of the blades (19) have different angles of inclination (&agr;, &bgr;) when viewed in the longitudinal direction of a wire (16). Thus, the cutting edges (21) contact a resin coating (16A) of the wire (16) at different timings while the wire (16) is being pushed in. The blades (19) of each blade portion (17) do not simultaneously come into contact with the resin coating (16A). Thus, a resistance during cutting can be small.

Abstract: A pressure-contact terminal includes: a contact portion formed on a tip end side of the pressure-contact terminal; and an electric wire connecting portion formed on a rear end side of the pressure-contact terminal have a bottom plate and a pair of side plates which are formed with a plurality of pairs of pressure-contact portions. In the construction, at least a pair of pressure-contact portions of the plurality of pairs of the pressure-contact portions has a pair of pressure-contact blades. Each of the pair of pressure-contact blades includes: a pressure-contact blade main body cut and bent up from the side plates; a blade portion formed on an outer periphery of the pressure-contact blade main body to cut a cover portion of a covered electric wire; a contact portion continuously formed from the blade portion to be in contact with a core of the covered electric wire; and a core retaining portion for retaining the core.

Abstract: A press-connecting terminal (1) includes a press-connecting portion (4) having press-connecting blades (9). The press-connecting blade (9) has a pair of opposed inner surfaces (9c) extending downwardly respectively from a pair of bladed, tapering guide surfaces (9a) which are slanting downwardly toward the axis of the electric wire (7), and a gap (G), formed between the pair of inner surfaces (9c), is smaller than the diameter (d) of a conductor (7b) of the electric wire (7). On the basis of at least one of the width (W) of each of the downwardly-extending inner surfaces (9c), the size of the gap (G), and the number (n) of the press-connecting blades (9), the total area (ST) of contact of the downwardly-extending inner surfaces (9c) with the conductor (7b) is set to a value greater than or equal to the cross-sectional area (&pgr;d2/4) of the conductor (7b). Therefore, an electrical resistance, developing between the conductor (7b) and each inner surface (9c), can be reduced.

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.
