A structure of a press-contacting holding part is not complicated so that press-contacting operation of press-contacting an electric wire to the press-contacting terminal is easily and precisely performed. According to the invention, an apparatus of press-contacting of electric wire includes a case holding part for holding case provided with a press-contacting terminal, an electric wire holding part for holding the electric wire positioned by the positioning part, a press-contacting driving mechanism for driving the electric wire held by the electric wire holding part so that the electric wire is pushed into a slot part of the press-contacting terminal to provide pressure contact therebetween.

A press-fitting device in which a terminal of a connector having a staggered arrangement section of the terminal of the connector is press-fitted into an insertion hole is provided. In the press-fitting device, a first terminal restricting member on which a guide section for restricting a vertical displacement of the terminals between the terminals along the lateral direction of the connector housing and a second terminal restricting member on which a guide section for restricting the lateral displacement of the terminals between the terminals along the vertical direction of the connector housing in an upper or lower part of the first terminal restricting member are provided. A guide groove to which terminals on an interior side of the connector housing are introduced is provided at a tip end portion of the guide portion positioned at the staggered arrangement section of the terminals.

Terminal press-fitting device

A bent connector terminal with improved stability when held within a groove () of a comb-shaped, press-fit jig (), the terminal aligned with a hole () of a printed circuit board () and to be press-fitted into the hole. In one embodiment, at least one widened portion () is formed on the connector terminal between a tip flange part () and a swelled or widened part (), the widening of the part () caused by bending of the connector terminal. The widened portion () and the swelled part () serve to stabilize the connector terminal within the groove () of the press-fit jig as the jig is used to press on the tip flange part (). In another embodiment, the connector terminal includes notches () at the location where the connector terminal is to be bent, to compensate for widening caused by the bending step so that no swelled or broadened area is produced at this region. In this embodiment, since no widening is produced at the bent region the press-fit jig grooves may be narrowed so that the bent connector terminal is supported evenly between the bend and the flange part () and stability is improved.

Angled terminal with flange for cooperation with press-fit jig

Cylinders are arranged in such a manner that they correspond to a plurality of pressure-blades by one-to-one, and desired pressure-blades are pushed downward by the corresponding cylinder rods, so that the desired pressure-blades are protruded from and fixed at the lower ends of the residual pressure-blades. The thus arranged pressure-blades are lowered with respect to the connector. Then, only the pressure-blades protruding from the lower ends of the other pressure-blades can conduct the operation of pressure-connection. Due to the foregoing, after the electrical wires F have been connected to the pressure-terminals of one connector all at once, in the pressure-connecting process of the other connector, only when the desired pressure-blades are selected and the selected pressure-blades are moved along the arrangement of the pressure terminals of the other connector, the wire harness of cross-wiring can be manufactured. Therefore, it is not necessary to frequently move the pressure-blades between the connectors.

Apparatus for making a wire harness

An inexpensive flat electric wire for a wire harness and an inexpensive wire harness utilizing the flat electric wire can be produced. A flat electric wire (P) is produced by juxtaposing a plurality of insulator-sheathed electric wire elements (a), each having a single core, on a plane; and by applying a reinforcing tape (51) on the juxtaposed wire elements (a) at a desired position over the width of the elements (a), whereby the wire elements (a) are secured together to each other by the tape (51) to form the flat electric wire (P) for a wire harness. A wire harness (d) having connectors at opposite ends is produced by winding the flat electric wire (P) for a wire harness on a reel (61) beforehand; by drawing the flat electric wire (P) from the reel (61); by measuring and cutting (A) the flat electric wire (P); by carrying the cut-off flat electric wire (P) in a juxtaposed direction while holding opposite ends of the cut-off flat electric wire (P) by grippers; and by treating opposite ends of the cut-off flat electric wire (P) during the carrying step by means of stripping (B) the insulator sheath, connecting (C) terminals (t), and attaching (D) connectors (C).
