2. Description of the Related Art The number of circuits in an automotive wire harness increases with the increase in electrical components, and some of them include several hundred circuits. Therefore, since it is very difficult to assemble and form a wire harness in which a group of electric wires satisfying this huge circuit is laid in a required form and assembled, the single wire harness is difficult to perform in terms of quality and work efficiency. A divided wire harness (hereinafter simply referred to as a divided harness) divided into several groups is formed, and inter-group connecting wires drawn from the divided harness group are gathered and connected to a connector of a mating divided harness of a mating partner. Thereafter, a method has been adopted in which the divided harness groups are assembled and bound to form a single wire harness satisfying the required number of circuits.

The split wire harness and the wire harness formed from the split wire harness apply a strong pulling force to the electric wire during assembling and molding, so that a crimp terminal having a strong pulling force is mainly used structurally or a crimp terminal and a crimp terminal are used. Is adopted.

"Problems to be Solved by the Invention" Generally, when connecting terminals to a group of wires, it is not necessary to peel off the wire covering of the insulation displacement terminal, and furthermore, it is easy to perform mechanical batch pressure welding, while the crimp terminal is In addition, it is difficult to mechanically collectively crimp, and the press-connecting terminal has a remarkable advantage in connection with the electric wire.

However, the split harness of the above-mentioned conventional means mainly uses crimped terminals or has a hybrid structure of crimping and crimping terminals, so there is a limit in automation of wiring and terminal connection, and the assembly formability of the divided harness group is good. However, there is a drawback in the formability of wire harnesses for automobiles that require mass production and high productivity.

SUMMARY OF THE INVENTION The present invention provides a wire harness assembling method and a wire harness connector that solve the above-mentioned problems of the conventional means.

Means for Solving the Problems The present invention for solving the above-mentioned technical problems is as follows: "A connector is arranged in a required form, a divided wire harness group forming a required circuit is formed, The terminals of the inter-group connecting wires drawn out of the harness group are assembled to the connector of the mating divided wire harness and connected to each other, and the divided wire harnesses are combined and assembled to form a single wire harness of the required circuit In one of the divided wire harnesses, "a press-fitting connector group accommodating the crimping terminals is exclusively arranged and formed, and the crimp terminals are attached to the inter-group connecting wires." Arrange and form the crimp connectors and attach crimp terminals to the inter-group connection wires. ” A method of inserting the connector of the side split wire harness into the post-insertion terminal accommodating chamber and connecting them together, and then assembling, binding, assembling and forming a pair of split wire harnesses, and disposing in the split wire harness The connector used in the wire harness assembling and forming method of the present invention for connecting the terminals of the wired electric wires of the divided wire harness is provided with an electric wire insertion opening above the terminal accommodating chamber group and press-fitting the terminal accommodating chamber.

[Operation] In the assembling and forming method of the present invention having the above-described configuration, the split harness assembled in pairs is provided with a split harness having a configuration dedicated to a press contact terminal in which only press contact terminals are arranged and wired, and a crimp terminal. Since it is layered and formed into a divided harness with a crimped terminal configuration and connected in a bundle, a dedicated harness dedicated to the crimp terminal is formed within the range where the crimp terminal can be configured, and collective connection of the wire group to the connector by mechanization Is possible in a wide range.

When the dual-purpose connector of the above embodiment is used, the arrangement of the connector is simplified.

"Example" Hereinafter, a detailed description will be given based on an example. First, with reference to FIG. 1 showing an embodiment of the assembling and forming method of the present invention, terminals of connection wires between groups of a pair of divided harnesses having required circuits are connected to connectors of a mating divided harness. In the case of forming a single wire harness by assembling the connected divided harnesses and then binding them together, one of the divided harnesses 1A is provided with a press contact terminal 6 in which the connector 2 is disposed and accommodated. The connection wires 5 are connected to the crimping terminals 7A for rear insertion, which are configured exclusively for the press-connecting terminals in which the wire group 4 is press-connected.

And the split harness that is paired with this split harness 1A
1B is a crimp terminal 7 in which the connector 2 is also arranged and accommodated.
The wire group 4 is crimped and connected to the wire, and the inter-group connecting wire 5 that has been drawn out has a crimp terminal
7A is installed.

That is, the connector of this embodiment is shown in FIGS.
Reference: A terminal accommodating chamber 9 having an electric wire insertion opening 8 at an upper portion. The terminal accommodating chamber 9 is a connector of a dual-purpose accommodating chamber into which any one of the press-contact terminals 6 and the crimp terminals 7 is inserted. .

It should be noted that the split harness 1A dedicated to the crimping terminal has the same condition as that of the wired wire group 4 connected between the crimping terminals 6 (since the crimping terminal is inferior to the drag force of the wire, the presence of unequal-length wires The circuit is selected and grouped to satisfy the wiring condition that satisfies the conditions.
Are grouped together by gathering specific circuits such as a U-turn circuit (closed circuit) branch joint circuit in which the above-mentioned electric wire equal length conditions are difficult.

The split harness 1A1B is connected to the split harness 1A1B by inserting the crimp terminal 7A of the inter-group connecting electric wire 5 into the post-insertion terminal accommodating chamber of the connector 2 of the mating split harness. Are assembled and united,
A single wire harness is assembled.

Next, a connector according to another embodiment used in the above-described molding method will be described with reference to FIG. The connector shown in FIG. 2 replaces the press-contact / crimp terminal connector of FIG.
The crimp terminal 7A of the inter-group connecting wire 5 has a shape in which a post-insertion terminal accommodating chamber 10 is integrally attached to a side end of the group of crimping terminal accommodating chambers 9 arranged side by side. Holding member for covering and locking the wire insertion opening 8 of the chamber 9 group
11 is provided so as to stabilize the posture of the insulation displacement wire in the terminal accommodating chamber 9.

In the split harness 1A, as shown in FIG. 3, a group of terminal chain reels 13 in which a press-contact terminal vertical chain 12 in which press-contact terminals 6 are vertically connected are wound in front of the connector 2 are arranged in parallel. The press contact terminal group is sent out from the reel group and is collectively inserted into the connector 2. At the same time, the electric wire group is mechanically simultaneously supplied from above the connector 2 to which the press contact connector is inserted, and collectively press-welded, thereby achieving extremely high efficiency. Molded.

[Effects of the Invention] As described above, the method of assembling and forming a wire harness according to the present invention provides a method of assembling and forming a wire harness by interconnecting and integrating divided wire harnesses.
