Must be accommodated in the connector. Therefore, there is a problem that the number of working steps is increased, required parts (crimp terminals, connectors, etc.) are increased, and the cost is increased. Furthermore, since the terminals connected to the internal circuit are laid out in a line in the connector accommodating portion provided in the electric connection box, there is a problem that a large number of terminals takes up space.

And the workability is very poor. In other words, the temporary binding harness obtained by sub-assembly of the electric wire group cannot be connected to the electric junction box that houses and assembles the internal circuit. As described above, when the connection work between the terminal of the wire harness and the electric connection box is performed on the wire harness assembly work table at the time of the actual binding, the connection work is extremely increased, and there is a problem that the cost is increased.

接端子２０にかからない。The cover 23 is fixed to the lower case 11 with the lock claw 17a of the cover mounting plate 17 inserted and locked in the lock hole 23f on the short side of the cover 23. In this state, the electric wire w is clamped and fixed between the electric wire holding ball 23g at the lower end of the cover 23 and the surface of the lower case 11 in a bent state. As described above, since the cover 23 is fixed to the case, the wire w connected to the press-contact terminal 20 is bent and fixed without opening the cover 23 even when a tensile force acts on the wire. As a result, it is possible to prevent the tensile force acting on the electric wire w from acting on the press-connecting portion. Further, in this state, the distal end surface 23a of the cover 23 is spaced from the distal end surface 16a of the press contact terminal mounting portion 16 so that the load by the cover 23 is not applied to the press contact terminal 20.

ることができる。As described above, the intermediate portion of the wire harness 15 is routed along the outer surface of the case with respect to the junction box 10 which houses and assembles the internal circuit, and a required electric wire is attached to the press-fit terminal mounting portion on the outer surface of the case. The internal circuit and the electric wire of the wire harness can be directly connected (that is, without a connector) simply by pushing the wire harness into the press contact terminal protruding from the terminal 16.

ワイヤハーネスの形成を高能率で行うことができる。As described above, one automatic press-connecting device is used for both press-connecting to the press-connecting terminal with the intermediate portion of the wire harness protruding from the outer surface of the case of the junction box and press-connecting to the press-connecting connector of the wire terminal. Therefore, even if the automatic pressure welding device is used, the cost does not increase, and the formation of the temporary binding wire harness can be performed with high efficiency.

上し、生産性を高めることができる。As is apparent from the above description, according to the present invention, the wire harness temporarily connected by connecting the press-connecting connector to the terminal is provided in the same electrical connection box as containing the internal circuit and assembled. Using an automatic pressure welding device, direct pressure welding connection can be made without a connector. Therefore, as compared with the case where a terminal is crimp-connected to a wire terminal of a conventional wire harness, the terminal is inserted into a connector, and this connector is fitted into a connector accommodating portion of an electric connection box and connected to an internal circuit, The number of parts can be greatly reduced, such as the elimination of terminals and connectors. In particular, since both the connection between the wiring harness and the internal circuit of the electric connection box and the connection with the connector are press-connected by the automatic press-connecting device, the work efficiency is remarkably improved, and the productivity can be improved.

The design of the wiring route can be facilitated.
