A wire harness capable of forming a short circuit by use of a plurality of electric wires and a joint connector while being slenderized and reduced in weight. The wire harness includes a plurality of circuit modules each forming a short circuit. Each of the circuit modules, includes a plurality of electric wires, and a plurality of external-connection connectors, connected to respective first ends of the electric wires, and a joint connector, connected to respective second ends of the electric wires to short-circuit the electric wires. The electric wires constituting the circuit modules are bundled together so that the joint connector of each of the circuit modules is discretely disposed so as to be located in a vicinity of at least one of the external-connection connectors included in the circuit module, around which electric wires a binding tape is wound.

Wire harness including short circuit and production method therefor

An electric wire with a terminal connector includes an electric wire and a female terminal connector crimped onto a core wire exposed at the electric wire. A female terminal connector has a wire barrel having a surface to be applied to the core wire. The surface has a plurality of recesses formed therein. Each recess has an opening edge. The opening edge of the recess includes first opening edges that are parallel to each other. The first opening edges are arranged to overlap with each other in the extending direction of the electric wire so that the first opening edges are present over the entire length of all over the plurality of the recesses on the crimping portion in the extending direction of the electric wire.

Terminal connector and electric wire with terminal connector

An electric wire with a terminal connector includes an electric wire and a female terminal connector crimped onto a core wire exposed at the electric wire. A female terminal connector has a wire barrel having a surface to be applied to the core wire. The surface has a plurality of recesses formed therein. Each recess has an opening edge. The opening edge of the recess includes first opening edges that are parallel to each other. The space between the recesses adjacent to each other in the extending direction of the first opening edge is set narrower than the space between the recesses adjacent to each other in the extending direction of the electric wire.

An electric wire with a terminal connector includes an electric wire and a female terminal connector crimped onto a core wire exposed at the electric wire. A female terminal connector has a wire barrel having a surface to be applied to the core wire. The surface has a plurality of recesses formed therein. Each recess has a parallelogram-shaped opening edge. The opening edge of the recess includes a pair of first opening edges that are parallel to each other and a pair of second opening edges that are parallel to each other and different from the first opening edges. The recesses are spaced in the extending direction of the first opening edges and are spaced in the extending direction of the second opening edges.

Rims of an opening of each recess form a parallelogram, and comprise two first opening rims that are parallel to a first direction and two second opening rims that are parallel to a second direction. The first opening rims of each of the recesses that are aligned along the first direction are arranged on a straight line along the first direction. The second opening rims of each of the recesses that are aligned along the second direction are arranged on a straight line along the second direction. The recesses are formed by pressing a wire barrel with a die where a plurality of protruding parts are formed so as to correspond to the recesses.

A plurality of recesses are formed on a surface of a wire barrel where an electric wire is provided. In a state before the electric wire is crimped onto the wire, barrel, at least one of sides comprising rims of an opening of each recess of a quadrangular shape is a crossing side crossing at an angle of from 85 degrees to 95 degrees to an extending direction. In a state before the electric wire is crimped onto the wire barrel, the crossing sides of a plurality of recesses positioned adjacent to each other in the extending direction are so arranged as to overlap with each other in the extending direction.

A terminal fittingincludes a main bodyto be coupled to a mating conductor, and a crimp contact sectionrearward from the main bodyThe crimp contact sectionis crimped on an end of a core wirein a covered electrical cableso as to surround the end. The core wireincludes a plurality of metallic strandsand is covered with a sheathto form the covered electrical cableSerrationsare provided on a contact surface of the crimp contact sectionfor surrounding the core wireEach serrationis a polygonal shaped recess with which the core wireengages upon crimping. Both diagonal corner portionsC of each serrationare rounded. Thus, the whole periphery of an opening edge around the recess penetrates an oxide layer on a core wire.

Electrical connector

A terminal () has a terminal main body () with a projection () to be engaged with a retainer (). A wire barrel () to be crimped to a core () of a wire (), an insulation barrel () to be crimped to an insulating coating () and a rubber plug barrel () to be crimped to a rubber plug () are successively arranged behind the main body (). Bottom parts of the wire barrel () and the insulation barrel () are at low positions having substantially the same height. A front end of the wire barrel () is crimped flat to suppress bend-up of the core (). The front end of the crimped wire barrel () is insertable to a position facing a projecting end of the retainer () when the terminal () is inserted to a proper position in a cavity () of a housing ().

Terminal fitting and a connector

A terminal fitting () has a connecting portion () to be connected with a mating connecting portion, and a crimping portion () continuous with the rear end of the connecting portion () and including a bottom plate () and crimping pieces () standing up from the bottom plate (). The crimping portion () is crimped into connection with a wire () while surrounding an end portion of the wire () by the bottom plate () and the crimping pieces (). The bottom plate () is formed with a reinforcing rib () extending in forward and backward directions.
