In order to achieve the above object, according to the first aspect of the present invention, a wire harness is formed by slitting an expandable slit in an axial direction into a groove. In a jig used for winding by a corrugated tube, a jig body having a substantially triangular developed shape is bent in a U-shape so as to pass through one vertex and in a direction to narrow the U-shape. A pair of gripping surfaces are provided so as to face each other by being bent as possible, the inner bottom portions of both gripping surfaces are introduction grooves for the wire harness, and the slits are widened at upper opening edges of both gripping surfaces. The guide flange edge is formed so as to protrude and allow the jig body to slide along the slit. Below the Nji edge is characterized in that the guide piece for restricting the advanced position of the corrugated tube at a predetermined position is formed to project outward at the time of introduction of the corrugated tube.

According to a second aspect of the present invention, a wire harness is passed through a corrugated tube in which an expandable slit is cut in the form of a groove in the axial direction, and a guide member extends along the length of the slit. In the jig for engaging, the jig body having a substantially triangular development shape,
A pair of gripping surfaces are provided facing each other by being bent in a U-shape so as to pass through one vertex and in a direction in which the U-shape is narrowed so as to bend and deform. A bottom portion is formed as an introduction groove through which the guide member passes and along which the wire harness extends along the guide member, and a restriction that protrudes above the guide member in the introduction groove in order to restrict the floating of the guide member. A member is provided, and a guide flange edge is formed so as to protrude and lock the slit at the upper opening edge of the both gripping surfaces so as to be able to slide and operate the jig body along the slit. It is characterized by the following.

In the invention according to the first aspect, when inserting the wire harness into the corrugated tube, first, the wire harness is passed along the introduction groove of the jig body. Then, the both gripping surfaces are pinched to narrow the opening edge side of the gripping surface, and the two guide flange edges are brought close to each other. In this state, the two flange edges which are close to one open end face of the corrugated tube are fitted, and the slit is split and widened and locked inside. After this,
By operating the jig body and the wire harness in the opposite direction, the wire harness is automatically inserted into the corrugated tube.

In the invention according to the second aspect, the guide member is introduced into the introduction groove of the jig main body in a lower side, and the wire harness is introduced along the guide member. Thereafter, the insertion operation is performed in substantially the same procedure as described above, and as a result, the insertion of the wire harness and the mounting of the guide member are performed simultaneously. During this time, the guide member is passed under the regulating member, and its posture is corrected so as to be along the introduction groove. Therefore, the guide member can be inserted without lifting or twisting. .

[0008]

[Effects of the Invention] The effects of the present invention are as follows. According to the invention of claim 1, in the work of inserting the wire harness into the corrugated tube, the gripping surface and the guide flange edge are set close to each other. Since the wire harness can be securely and smoothly housed in the tube, the work efficiency can be improved.

According to the second aspect of the present invention, since the guide member is prevented from rising or twisting by the restricting member, the guide member and the slit are mounted in a state where they are securely engaged in the longitudinal direction. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; 1 to 6 show the first embodiment of the present invention.
It shows an embodiment. The jig body 1 is integrally formed of a synthetic resin material. The jig body 1 has a substantially triangular developed shape, and is bent in a U-shape symmetrically with a substantially uniform groove width around an axis passing through one vertex. As a result, the surface of the jig body 1 facing left and right becomes the gripping surface 2 for knob operation, and the inner bottom of the jig body 1 is a wire harness 3.
And a guide member 4 having an H-shaped cross section having grooves 10 on the left and right.
And an introduction groove 11 for introducing the same.

The jig body 1 is provided with an appropriate bending property, and can be elastically deformed so as to narrow the opening side by a gripping operation of the gripping surface 2. In addition, both gripping surfaces 2 are formed with lightening circular holes 5.

A guide flange edge 6 is formed on the upper edges of the two gripping surfaces 2 so as to project outward along the entire edge, and can be engaged with the inside of the slit 8 of the corrugated tube 7. However, the front end sides of both gripping surfaces 2 are cut out to the outside except for a part of the front end of the guide flange edge 6. As a result, a part of the distal end side of the guide flange edge 6 becomes a free end (hereinafter, this part is referred to as an extension part 9), and when the periphery of the extension part 9 is pinched and elastically deformed in the recess direction, the guide is formed. It can be fitted into the groove 10 of the member 4. Reference numeral 13 denotes a guide piece which is integrally formed on both ends outwardly at a position corresponding to the lower surface of the groove 10 in a state where the guide member 4 is sandwiched at the distal end of the jig main body 1. It functions to restrict the corrugated tube 7 from protruding from the groove 10 at the time of introduction.

Next, the operation and effect of this embodiment according to the above configuration will be specifically described. First, the guide member 4 is placed in the introduction groove 11 of the jig main body 1 (state in FIG. 2). Next, the wire harness 3 is placed along the upper surface of the guide member 4 and set up and down in two steps in the introduction groove 11 (state in FIG. 3).

Thereafter, the rear ends of both gripping surfaces 2 are strongly pinched, and the rear ends of both guide flange edges 6 are brought close to each other. Then, one end of the corrugated tube 7 is fitted here, and the two guide flange edges 6 are engaged with the inside of the slit 8 while splitting and widening the slit 8 (state in FIG. 5). Next, the jig body 1 is held with one hand, and the corrugated tube 7 and the front ends of the guide members 4 and the wire harness 3 are also held together with the other hand, and the corrugated tube 7 is advanced as it is. Manipulate.
As a result, the corrugated tube 7 is guided and regulated by the extension portion 9 at the tip end of the jig body 1 and the guide piece 13 and enters the groove 10 of the guide member 4, and the two groove portions 10 of the guide member 4 extend in the longitudinal direction of the slit 8. And the wire harness 3 is placed in the corrugated tube 7 with the wire harness 3 placed on the guide member 4. If this operation is repeated in order, the operation of winding the corrugated tube 7 around the wire harness 3 and the guide member 4 is completed.

Further, according to this embodiment, during the winding operation, if this portion is pinched so that both extension portions 9 are engaged with the groove portions 10 of the guide member 4, the lifting and twisting of the guide member 4 are restricted. Also, an effect that the work can be performed in a normal posture while performing the operation can be obtained.

FIGS. 7 and 8 show another embodiment of the jig. In the above-described embodiment, the extension portion 9 is set as a restricting member that restricts the lifting of the guide member 4.
Instead, bolts 12 are mounted. That is, the bolt 12 is inserted from the outside of the one gripping surface 2, crosses the inside of the introduction groove 11 slightly above the thickness of the guide member 4, and is fixed by the nut stop outside the other gripping surface 2. . Further, in this embodiment, a cutout portion is not provided at the front end of the jig body 1 as in the above-described embodiment.

According to the jig thus constructed, the guide member 4 is passed under the bolt 12 into the introduction groove 11, and then the wire harness 3 is set thereon.
Thereafter, it is inserted into the corrugated tube 7 in the same procedure as described above. During this time, the guide member 4 is
The guide member 4 can be reliably and smoothly engaged with the slit 8 because the guide member 4 is inserted through the corrugated tube 7 while the upward displacement is regulated by the above.

In the above description of both embodiments,
Although the example in which the guide member 4 is inserted into the corrugated tube 7 together with the wire harness 3 has been illustrated and described, the guide member 4 is not necessarily required, and only the wire harness 3 may be simply passed through the corrugated tube 7. . Therefore, a regulating member such as a bolt can be omitted as necessary.
