Description

[Detailed Description of the Invention] As known from Japanese Patent Publication No. 56-4167, the method for manufacturing wire assemblies is as follows: covered wires are routed around using a so-called numerically controlled automatic hand, and are set upright on the top of a wiring table. A method is generally known in which the cable is bent by a branch bin and connected to terminals provided in connector housings disposed at various locations around the wiring table. However, in this method, (1) the housing insertion positions are dispersed, and furthermore, the already inserted wire becomes an obstacle, making the insertion work difficult.

■Wiring including joint wires (branches) is not practical due to mechanical structure.

■It had drawbacks such as requiring a complicated and expensive wiring table (drawing board). The present invention was made to eliminate these drawbacks, and among the plurality of housings used in the set 111Is,
First, the terminals to be inserted into each terminal hole provided in the first housing and the covered wires to be connected to the terminals are crimped, and then sequentially inserted into the terminal holes to wire the covered wires to be connected to the first housing. complete. In this way, the wiring of each housing spatula is carried out in sequence, but of course, in the process after the installation) J. It will be crimp-connected to the other end of the covered wire connected to the terminal.

Therefore, until this work is started, the covered wire whose terminal has been inserted is not cut into the hole, but is kept connected to the WLIiA supply source, and when this work is started, the covered wire is first taken out and measured. Add or subtract from the wire length of the measuring device, then pull out or pull back the III wire further to reach the predetermined circuit length (covered wire length), grip the wire at a predetermined point with the auto hand, and If a method is adopted in which the wire is cut at a certain point, a terminal is crimped thereon, and then inserted into a terminal hole in a subsequent housing, no conventionally known wiring stand or automatic wiring device is required.

To further summarize the present invention, if the most ideal method of the present invention is adopted, one terminal crimping device and one housing insertion device are each provided at a predetermined location, and the terminals are inserted into the housing after crimping one after another by an automatic hand. If this is done, it is easy to change the wire assembly of any circuit by simply replacing the automatic hand and the computer program that controls and instructs the amount of pull-out and pull-back of the covered wire (wire length). Embodiments of the present invention will be described in detail below with reference to the drawings.

The partial assembly wire circuit diagram shown in FIG. 1 shows eight connector housings 1, 2.

It is configured to be pulled out downward in Figure (b).

Further, the support frame 108 that supports the capstan 106 and the pinch roller 107 is connected to the opposing arm 111 of the wire support arm 100.
The electric wire support arm 100 is configured to be movable along the entire length of the electric wire support arm 100 along an arcuate groove 110 provided on the inner wall of the electric wire support arm 100 .

Further, the support frame 108 has a rod 111 pivotally attached to its right end.
and is moved left and right by a piston mechanism 112 that expands and contracts the rod 111.

Further, a piston mechanism 118 is fixed to the left end of the support frame 108 as shown in Figure #18 (b), and the electric wire 8 is clamped to the tip of a clamp rod 114 that is driven by this piston mechanism to expand and contract. Clamp mechanism 115
is provided.

As shown in the plan view of FIG. 8(0), the details of the clamp mechanism 115 include a roller 117 rotatably attached to a frame 116, a roller 117 whose right end is pivotally supported by the frame 116, and a spring 118 at its right end. It is composed of a clamp 119 that is elastically pulled to the side, and holds an electric current [18] interposed between the clamp 119 and the roller 117.

When the clamp mechanism is located at the position indicated by the dotted line frame 115 in FIG.

One to ten units are movably installed on the movable frame 410.

The above-mentioned intermediate peeling device is a utility model published in 1986-601.
No. 56-19819 is used.

Further, the thrusting device 60 may be of a generally known type, but the one shown in FIG. 61, cut off the tip, peeled off the skin, pulled back the oven, inserted it again into the crimping device 62, and applied the coating II.
It is constructed so that a terminal can be crimped onto the tip of the 8n.

In the case of the B end, the automatic hand 201 grips and cuts it (the cutting part is not shown), and the same operation is performed for the B end.

The terminal to be crimped to the tip is appropriately selected depending on the structure of the terminal hole of the housing 1.2.8, but a so-called bullet type terminal as shown in Fig. 1s4 is crimped, and it is already placed in the housing. Preferably, it is inserted into the female cylindrical terminal of the installed built-in terminal.

That is, the above-mentioned crimping device 62 becomes complicated in order to enable crimping of various terminals to the terminal holes of the housing and the tip of the covering it 8 n accordingly.

However, if the structure of the terminal receiving portion at the other end of the various terminals used in this housing is constructed so as to be able to fit and connect with the bullet terminal described above, the crimping device 62'ri can be simplified and convenient. Accordingly, terminals 18.14. shown in FIG.
All 16, 20, 22, 27, and 8°2 firings use the bullet terminal shown in Figure 4.

Next, although the housing support stand 800 is not shown in detail, as an example, each type of housing 1, 2, .
8 Each terminal is fed sequentially into individual support channels, and after the terminal has been inserted into the housing located at the final end of the channel, the housing can also be removed by pulling out the wire with an automatic hand while holding the wire connected to the last inserted terminal. It is better to adopt the model.

As described above, although the present invention requires the above-mentioned various devices, it is possible to automatically complete the assembled wire by sequentially transporting the wires by auto-hand.
The conventional assembly work by workers is no longer required.
