  • Patent number: 10205264
    Abstract: A joint connector includes shorting members (30) and a shorting member accommodating portion (50) for holding the shorting members (30). The shorting member holding portion (50) includes clamping portions (52, 54, 56 and 58) capable of clamping the shorting members (30) from both sides in a clamping direction and a clamping/fixing portion for constraining these clamping portions (52, 54, 56 and 58) to each other to fix the clamping portions at clamping positions where the clamping portions clamp the shorting members (30). At least some of the clamping portions are constraining clamping portions including shorting member constraining portions for constraining the shorting members (30) to restrict relative displacements of the shorting members (30) in a terminal projecting direction at the clamping positions.

  • Publication number: 20190044252
    Abstract: A wire with terminal (10) includes at least one wire (11) having a core (13) and a terminal (12) connected to the wire (11). The terminal (12) includes a wire barrel (16) to be caulked and crimped to the core (13). At least one end part of the wire barrel (16) in an extension direction of the wire (11) is provided with an enlarged diameter portion (20) enlarged in diameter toward the one end part. At least one recess (24E) is provided at a position corresponding to the enlarged diameter portion (20) and in a region configured to come into contact with the core (13) in a placing surface (23) of the wire barrel (16) where the core (13) is arranged.

  • Publication number: 20180337463
    Abstract: It is aimed to realize miniaturization. A power distribution device (Da) is for supplying power to a plurality of loads (L) and includes an input-side conductive path (10) to be connected to a battery (B) (power supply), a plurality of terminal holders (13) each including an input-side terminal fitting (20) connectable to the input-side conductive path (10), and a plurality of output-side conductive paths (37) configured to connect the input-side terminal fittings (20) and the loads (L). Since the number of the terminal holders (13) to be connected to the input-side conductive path (10) is a minimum necessary number corresponding to the number of the loads (L), miniaturization is possible.

  • Publication number: 20180159265
    Abstract: A joint connector includes a connector conductor part and an insulating housing for holding the connector conductor part and wire-side terminals to be connected to the connector conductor part. The insulating housing includes an outer wall (45) enclosing an accommodation space for accommodating wire-side terminals and separation walls dividing the accommodation space into terminal accommodating chambers (41). The separation walls include first separation walls (71) between the terminal accommodating chambers for respectively accommodating the wire-side terminals to be insulated without being shorted to each other and second separation walls (72) interposed between the terminal accommodating chambers for respectively accommodating the wire-side terminals to be shorted to each other. The first and second separation walls (71, 72) are shaped so that outer ends (71a) of the first separation walls (71) and outer ends (72a) of the second separation walls (72) are different in appearance.

  • Publication number: 20180131117
    Abstract: A joint connector is provided which can suppress the abrasion of contact parts due to relative displacements between wire-side terminals and a shorting member. The joint connector includes a plurality of wire-side terminals (20), a shorting member (30) including a base portion (32) and a plurality of terminal fitting portions (34), and an insulating housing (HG) defining a plurality of terminal accommodating chambers (41) and configured to hold the shorting member (30). The insulating housing (HG) includes a terminal holding housing portion (40) defining the terminal accommodating chambers (41) and configured to respectively lock the wire-side terminals (20) and a shorting member holding housing portion (50) configured to hold the shorting member (30). The both housing portions (40, 50) are so connected while restraining each other as to allow relative displacements between the both within a limited range.

  • Publication number: 20180090896
    Abstract: It is aimed to provide a method and a joint connector for shorting a plurality of wires to each other, the method and the joint connector being capable of flexibly coping with the number of the wires. A joint connector includes a plurality of wire-side terminals (20) to be mounted on a plurality of wires (10), a plurality of insulating housings (30) and a shorting member (40). Each wire-side terminal (20) is inserted into a terminal accommodating chamber of the corresponding insulating housing (30). The plurality of insulating housings (30) are united with each other while being arranged in a specific arrangement direction. The shorting member (40) is inserted into each of the united insulating housings (30) and fit to each wire-side terminal (20), whereby the wire-side terminals (20) are electrically connected to each other via the shorting member (40).

  • Patent number: 9893439
    Abstract: It is aimed to provide a terminal fitting capable of preventing a large force from acting on joint portions of a wire connecting portion and another constituent component formed separately from the wire connecting portion. The terminal fitting includes a wire connecting portion (10) to be connected to an end part of a wire (30) and another constituent component (20) formed separately from the wire connecting portion (10) and to be arranged in front of the wire connecting portion (10). The other constituent component (20) includes a joint piece (24) to be overlapped on the wire connecting portion (10) and joined. A part of the wire connecting portion (10) behind a part to be crimped to a core (31) of the wire (30) is joined to the joint piece (24).
