Description

  The present invention relates to a method of attaching a pressure contact connector for attaching a pressure contact connector to a pressure contact wire included in a wire bundle.

  9 and 10 show a method of attaching the pressure connector disclosed in Patent Document 1 below. This method of attaching the press contact connector is to attach the press contact connector 120 to a plurality of press contact wires 111 included in the wire bundle 100.

  The wire bundle 100 is a wire bundle composed of a plurality of pressure welding wires 111 and a plurality of non-pressure welding wires 112. The plurality of pressure welding wires 111 are wires that are joint-connected by the pressure welding connector 120.

  The press-connecting connector 120 houses a plurality of press-contacting blades that press-contact a plurality of electric wires in a housing formed of an insulating resin. The plurality of press contact blades housed in the press contact connector 120 are joint terminals in which the press contact blades are electrically connected to each other by a conductor.

  In the method of attaching a press contact connector of Patent Document 1, the press contact connector 120 is attached to a plurality of press contact wires 111 by the following procedures (A1) to (A4).

  (A1) First, on the wiring board 130, along the path M1 in which the electric wire bundle 100 is bent into a bowl shape by the three electric wire support jigs 141, 142, and 143 arranged on the wiring board 130. Arrange. The three wire support jigs 141, 142, and 143 are arranged so that the shape connecting these jigs is a right triangle.

(A2) Next, the pressure welding wires 111 are extracted from the wire bundle 100 wired in a bowl shape, and the plurality of extracted pressure welding wires 111 are routed along a path M2 bent in a bowl shape. The saddle-shaped path M2 is a right triangle formed by the wire support jig 144 disposed diagonally to the wire support jig 142 and the wire support jigs 141 and 143 at both ends of the path M1.
The route M1 and the route M2 have the same length.

  (A3) Next, the press-connecting connector 120 is disposed in the middle of the path M2, and the press-contacting wires 111 on the path M2 are press-contacted to the press-connecting connector 120.

  (A4) Next, the bundle of the pressure welding wires 111 to which the pressure welding connector 120 has been attached is returned to the bundle of the non-pressure welding wires 112 in the path M1, and bundled with taping or a binding band as shown in FIG. The tool 150 forms a bundle of wires bundled in the non-pressure welding wire 112.

  In the method of attaching the pressure contact connector in Patent Document 1, since the lengths of the path M1 and the path M2 are the same, the pressure contact wire 111 to which the pressure contact connector 120 is attached is returned to the bundle of the non-pressure contact wires 112. It is possible to prevent the electric wire 111 from protruding (protruding) and to form a neat electric wire bundle.

  However, in the method of attaching the pressure contact connector in Patent Document 1, before attaching the pressure contact connector 120, the wire bundle 100 is bent into a shape along the saddle-shaped path M1, or the pressure contact wire 111 is shaped along the saddle-shaped path M2. It is necessary to bend it. Therefore, when the bending rigidity of the wire bundle 100 is high and it is difficult to bend, there is a problem that the pressure contact connector 120 cannot be attached.

  Further, in the method of attaching the press contact connector in Patent Document 1, since the press contact connector 120 is attached by bending it into a hook shape as shown in FIG. 9, the press contact connector is not bent into a hook shape but in a substantially straight wiring state. Compared with the case where 120 is attached, it is necessary to secure a surplus length for securing a bowl-shaped bent shape. Therefore, when it is difficult to give extra length due to restrictions on the wiring space on the side of the wiring object (for example, the vehicle body) for wiring the wire bundle 100, or restrictions on signal transmission performance, There was a problem that the pressure contact connector 120 could not be attached.

  Therefore, an object of the present invention is to solve the above-described problems, and even in the case of an electric wire bundle that is difficult to bend and an electric wire bundle that is difficult to give an extra length, An object of the present invention is to provide a method of attaching a pressure contact connector that can easily attach the pressure contact connector.
