Cable branching structure
View Patent ↗An electric wire branching structure ( 1 ) branches a shielded electric wire ( 30 ) with a plurality of electric wires ( 10 ) from a main wire ( 30 A) to a plurality of branch wires ( 30 B, 30 C). The electric wire branching structure ( 1 ) includes an electroconductive shield member ( 100 ) configured to cover the electric wires ( 10 ) corresponding to the main wire ( 30 A) and the branch wires ( 30 B, 30 C). The shield member ( 100 ) has a plurality of electric wire insertion openings ( 111, 112 ) for the electric wires ( 10 ) corresponding to the branch wires ( 30 B, 30 C) to be inserted for each of the branch wires ( 30 B, 30 C).
1. An electric wire branching structure comprising:
an electroconductive shield member configured to shield a first electric wire wired from a main wire bundle to a first branch wire and a second electric wire wired from the main wire bundle to a second branch wire,
wherein the shield member has a first electric wire insertion opening for the first electric wire to be inserted and for wiring the first electric wire from the main wire bundle to the first branch wire, and
a second electric wire insertion opening for the second electric wire to be inserted and for wiring the second electric wire from the main wire bundle to the second branch wire, the second electric wire insertion opening being formed separately from the first electric wire insertion opening, such that the second electric wire insertion opening and the first electric wire insertion opening are unconnected to each other, and
wherein the shield member includes:
a main wire shield member formed of a metal shell and a one-piece construction with a connector, with the first electric wire insertion opening and the second electric wire insertion opening and configured to shield the first electric wire and the second electric wire,
a first branch wire shield member, separate from the first electric wire and the second electric wire, connected to the first electric wire insertion opening of the main wire shield member and configured to shield the first electric wire of the first branch wire, the first branch wire shield member being formed of a braided wire, and
a second branch wire shield member, separate from the first electric wire and the second electric wire, connected to the second electric wire insertion opening of the main wire shield member and configured to shield the second electric wire of the second branch wire, the second branch wire shield member being formed of a braided wire,
wherein respective ends of the first and second branch wire shield members are crimped by first and second crimp members, respectively, in such a state that the first and second electric wire insertion openings of the main wire shield member are covered, and thereby attached to the main wire shield member.
2. The electric wire branching structure according to claim 1 , wherein the connector is fitted in a mating connector connected to an apparatus in a metal case.
3. The electric wire branching structure according to claim 2 , wherein the connector comprises an insertion hole through which a fixing member used for fixing the connector to the metal case is inserted.
