A preferred embodiment of the present invention will be described in detail. Referring to FIG. 1 which is an exploded perspective view showing a part of a holding member 20 and a mounting arm 39 of an electric wire with terminal showing an embodiment of the present invention, this holding material 20 is an electric wire with terminal TW. Is removably fixed via a mounting arm 39 to a transfer disk 34 that transfers the to the insertion hands 51 and 52 of the insertion unit 50.

The mounting arm 39 is fixed to a fixing portion 39A along a tangential direction of the disk 34 with a bolt 301.
And a first arm portion 39 extending from one end of the fixing portion 39A along the diametrical direction of the disk 34 perpendicular to the fixing portion 39A.
B is an angle member integrally having a second arm 39C extending in parallel with the first arm 39B from the other end of the fixing portion 39A. A large number of the mounting arms 39 are fixed to the outer periphery of the disk 34 at regular intervals in the same circumferential direction.

The holder 20 has a first block 21 attached to the first arm 39B and a second block 22 attached to the second arm 39C, and holds the electric wire with terminal TW. It is for holding. In the electric wire with terminal TW, the terminal T on one end is accommodated in a concave portion 201 formed in the first block 21, and the terminal T on the other end is formed in a concave portion 201 formed in the second block 22.
, It is hung over both blocks 21 and 22 and hangs in a U-shape.

Each of the blocks 21 and 22 has bottomed fitting holes 21A and 22A on the lower surface thereof, and each of the arms 39B and 39C has a fitting hole 21A of the corresponding block 21 and 22. Positioning pins 39E corresponding to 22A, 3
9F is erected. And these pins 39E, 39
By fitting F into the fitting holes 21A and 22A of the blocks 21 and 22, the blocks 21 and 22 can be positioned at the corresponding arms 39B and 39C. Further, a fixing member 39G is attached to each of the arms 39B and 39C, and the blocks 21 and 22 and each of the arms 39B and 39C are detachably connected by the fixing member 39G. A screw member can be used as the fixing member 39G. Block 2
When the first and the second members 22 are formed of a magnetic material, a permanent magnet can be used.

Referring to FIG. 2 which is an enlarged perspective view showing the main parts of the blocks 21 and 22, each of the blocks 21 and 22 will be described.
The concave portion 201 accommodates the terminal-attached electric wire TW in a non-rotatable state in a state where the distal end portion of the terminal T is opened so as to be grippable.
And a slit 203 for allowing the insertion and removal of the terminal T with respect to the recess 201 by permitting the insertion of the electric wire with terminal TW.

The concave portion 201 defines a rotation restricting surface 204 for restricting the rotation of the terminal T. In the example of FIG. 2, the rotation restricting surface 204 is embodied by forming the upper portion of the concave portion 201 into a rectangle along the outer diameter of the terminal T. The slit 203 is set to have a width W1 necessary and sufficient to allow the electric wire with terminal TW to pass therethrough, and is formed over the entire length of the blocks 21 and 22 in the height H direction. Therefore, the worker can use the terminal T of the terminal-attached electric wire TW.
First, the terminal-attached electric wire TW is slit 203
The terminal T is then lowered, and the lower surface thereof is seated on the positioning surface 202, whereby the terminal T
Can be held in the recess 201. And terminal T
Is held by the rotation restricting surface 204 so that the terminal T of the wire with terminal TW cannot be rotated, and the positioning surface 202 positions the lower surface of the terminal T. The terminal T is securely stopped and held in a unique posture.

The rotation restricting surface 204 described above is
It may be embodied by a member different from 1 and 22. In that case,
The rotation regulating surface 204 that regulates the rotation of the terminal T is
Since it is constituted by members different from 1 and 22, the shape of the block can be simplified. Referring to FIG. 3 which is a perspective view showing another embodiment of the present invention, a rotation restricting surface 204 is shown.
In the case where is realized by a member separate from the blocks 21 and 22, the pieces 23 may be laminated on the upper surfaces of the blocks 21 and 22, and the rotation regulating surface 204 may be defined on the pieces 23. FIG.
In the example, the rotation restricting surface 204 includes a pair of side surfaces 231 and 232 sandwiching the terminal T from both sides, and the piece 23 defines an opening 233 that opens the front surface of the terminal T. In this configuration, since the terminal T is sandwiched between the pair of side surfaces 231 and 232 that open the front of the terminal T, the rotation of the terminal T fitting is regulated.
04 becomes simple. Note that, in the example of FIG.
In order to avoid interference with the stabilizer T1,

Referring to FIG. 4 which is a perspective view showing still another embodiment of the present invention, in the configuration shown in FIG. 4, a terminal T fitting is attached to a piece 24 which is a member separate from the blocks 21 and 22. The rotation regulating surface 204 including a pair of side surfaces 241 and 242 sandwiched from both sides is defined, and is connected to the slit 203 at the front of the accommodated terminal T to allow insertion of the wire with terminal TW. The necessary and sufficient insertion port 243 is partitioned. In this configuration, the terminal T is sandwiched between the pair of side surfaces 241 and 242 that open the front of the terminal T, and the rotation of the terminal T is also restricted by a portion that defines the insertion port 243 of the piece 24.

When the electric wire with terminal TW is loaded, each arm 21 or 22 in which the electric wire with terminal TW is previously loaded is manually or by using a transfer robot (not shown). It only needs to be attached to 39B and 39C. Then, by rotating the disk 34 intermittently, the electric wire with terminal TW can be conveyed to the subsequent unit.

As described above, in the above configuration,
Even in the manual operation, the terminals T of the terminal-attached electric wire TW can be reliably positioned in a unique posture, and the positioned terminals T can be gripped and taken out by the insertion hands 51 and 52. Even when the manufacturing process and the terminal insertion process are performed on separate lines, it is easy to transfer the terminal T to the hands 51 and 52 of the insertion unit 50 in a state where the terminal T of the wire with terminal TW is positioned. This has a remarkable effect that automation can be easily realized.

When the pieces 23 and 24 are employed, the shapes of the blocks 21 and 22 can be simplified, so that there is an advantage that the manufacturing cost of the blocks 21 and 22 can be reduced accordingly. is there. Further, when the configuration shown in FIG. 3 is employed, the shape of the rotation restricting surface 204 is simplified, so that there is an advantage that the manufacturing cost of the blocks 21 and 22 can be reduced accordingly.

On the other hand, when the configuration shown in FIG. 4 is employed, the terminal T is sandwiched between the pair of side surfaces 231 and 232, and the rotation of the terminal T is also restricted by the portion that defines the insertion opening 243 of the piece 24. Therefore, there is an advantage that positioning accuracy is improved. The above-described embodiment is merely a preferred specific example of the present invention, and the present invention is not limited to the above-described embodiment.
