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 electrical connector comprises a plurality of electrical connector contacts which have insulation-displacement portions at first ends thereof and slidable pin-engaging portions at second opposite ends thereof whereby all wire-wrap electrical connections have been eliminated and all electrical connections between external wires and pin contacts of a second electrical connector are solderless. A gas tube over-protection printed circuit board can also be connected to the pin contacts of the second electrical connector in a solderless manner.

Abstract: An insulation displacement terminal fitting is provided to avoid cracks when V-shaped blades (16) are embossed into the terminal fitting. A deformation-facilitating portion (17) is formed in the terminal fitting for increasing a stretching degree of a portion of a side wall (15) that becomes an edge (16A) at the leading end of the V-shaped blade (16). The deformation-facilitating portion (17) includes a weakened portion (17A) and at least one connecting portion (17B) at locations on the blade (16) continuous with the side wall (15). Since connecting portions (17B) of the deformation-facilitating portion (17) are stretched to a large degree during embossing, a stretching degree of a portion near the edge (16A) can be small, thereby preventing cracks in the edge (16A).

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 is provided to avoid problems in producing and handling a wiring harness when one conductive path which is branched from a main path of the wiring harness and returns thereto again after passing via branch paths is constructed. To achieve this objective, a cutter 25 is provided between two blade-type terminal fittings 20a, 20d of a joint connector 10, and a main wire Waa is connected with the two blade-type terminal fittings and cut therebetween by the cutter 25. By connecting a branching connector 40 with the joint connector 10, branch terminal fittings 41a, 41d are connected with the blade-type terminal fittings 20a, 20d. Since all main wires forming a wiring harness WH are allowed to have the same length and to be bundled together, there is no problem in producing and handling the wiring harness WH.

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.

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).

Abstract: A pressure contact terminal fitting 20 is inserted into a terminal housing chamber until it reaches the correct position, whereupon two protruding members 26 and 29 formed on the terminal fitting 20 make contact with corresponding receiving members 18 and 16. In this way, a pushing force exerted by an electric wire on a pressure contact member 24 is resisted by the receiving members 18 and 16.

Abstract: An insulation displacement contact terminal has a pair of side walls, an a pair of pressure contact blades that are mutually opposing and formed by partial bending away from the side walls. When an insulated wire is inserted between the pressure contact blades along a first direction, edges of the pressure contact blades bite into the insulation of the insulated wire so as to make contact with the inner core wire of the insulated wire. The pressure contact blades each have a curved part that is continuous from the side walls, and each curved part has a radius of curvature such that when the pressure contact blades are bent from the side walls and when a pulling force is applied to the insulated wire in a second direction that intersects with the first direction, concentration of bending stress acting on the pressure contact blades is relieved.

Abstract: In a pressure-contact terminal, a pair of pressure-contact blades are bent in such a manner that they are inclined with respect to their respective side walls of the terminal. A covered electric wire is inserted into between the side walls to thereby allow the pressure-contact blades to bite the covered electric wire. After then, the covered electric wire is pulled backwardly to thereby change the inclination angles of the pressure-contact blades greatly and, while the covered electric wire remains pulled backwardly, a clamping portion formed in the terminal is clamped to thereby fix the covered electric wire. By increasing the inclination angles of the pressure-contact blades, the pressure-contact blades can be contacted with a core included in the covered electric wire with a high contact load.

Protrusions of a second member are engaged with the groove portions of the first member. The second member is pressed so that the covered wires are pressed against press-fit blades of the terminal so as to attain electric conductivity. By ultrasonic vibration in the pressing condition, the first member and second member are fused with each other. At the same time, by ultrasonic vibration, the cores of the covered wires are fused with each other and the core and the press-fit blades are fused with each other. By the fusing of the cores mutually and the core and press-fit blades, the contact area is increased thereby decreasing contact resistance.
