Connecting structure for electric wire to shield case of apparatus
Therein is provided with a connecting structure to the shield case of an apparatus so that a number of the connector parts are decreasing and that connecting operation is facilitated. The connector includes a insulative first housing fixed in a state of being inserted into a through hole, a first terminal held by the housing to face the through hole and connected to the electric circuit. The second housing of the electric wire side is fitted to the first housing. The second terminal is connected to the first terminal. Sealing rings are provided between the outer periphery of the housings and the through hole on outer periphery of the housings so that the bracket fixed to the shield case is electrically connected to shield layer of the shield electric wire. A connecting member electrically connects the bracket and the shield layer outside of the second housing.
1. A connecting structure, comprising a metal shield case and a shield electric wire, wherein:
the metal shield case includes:
an insulative first housing fixed in a state of being inserted into a through hole of the metal shield case;
a first terminal held by the first housing;
a seal ring provided at least on an outer periphery of the first housing for sealing an interval between the outer periphery of the first housing and the through hole; and
a metal bracket fixed to the metal shield case; and the shield electric wire includes:
a center wire;
a shield layer around the center wire electrically connected to the metal bracket;
an insulative second housing fitted to the first housing by being inserted into the through hole; and
a second terminal connected to the center wire of the shield electric wire and connected to the first terminal in fitting the second housing and the first housing to each other.
2. The connecting structure according to claim 1 , wherein the metal bracket is integrally provided with the insulative second housing, and the metal bracket is fixed to the metal shield case, thereby fixing the insulative second housing in a state of the insulative second housing being fit to the insulative first housing.
3. The connecting structure according to claim 1 , wherein:
the first terminal further includes a terminal main body extending through the insulative first housing, and a fitting projected portion extending from the terminal main body;
the second terminal includes a fitting recess portion that receives the fitting projected portion; and
the first and second terminals are connected by fitting the fitting projected portion and the fitting recess portion to each other.
4. The connecting structure according to claim 1 , wherein the shield electric wire comprises a plurality of the shield electric wires, and the first and second terminals comprise a plurality of first and second terminals that correspond respectively to the shield electric wires.
5. The connecting structure according to claim 4 , wherein the through hole comprises a plurality of through holes, and the insulative first housing and/or the insulative second housing comprises a plurality of housing elements inserted respectively into the through holes, the plurality of housing elements being integrally formed to be continuous with each other at portions external to the through holes.
6. The connecting structure according to claim 1 , further comprising:
connecting member that connects the metal bracket and the shield layer at a portion external to the insulative second housing;
an inner portion of the insulative second housing including a cavity into which the shield electric wire is inserted; and
a sealing member that seals between the shield electric wire and the second insulative housing, the sealing member being arranged inside the cavity.
