While the protective frame 9 is fixedly attached, arms 12 and 13 are provided from both ends of the opening of the protective frame 9 inwardly and obliquely inwardly to prevent electric wires from coming off. The space 14 is formed so that the wire can be inserted into the protective frame 9 when the electric wire is exposed to the outside of the opening and is pushed into the space 14.

[Problems to be solved by the device]

However, in the bundled wire tool shown in FIG. 6 as a prior art, since the wire holding portion is a cylindrical body, if the wire is a parallel wire such as a connector wire, after the wire is inserted, as shown in FIG. Since it is rounded, twisting of the connector wire is likely to occur, and there is a lot of waste in the vertical direction in terms of space. Further, if the width of the split portion is large, the electric wire tends to come off, and if the width is small, it is difficult to insert the electric wire.

Further, in the protector shown in FIG. 8, there is a problem that the electric wire is easily separated from the space of the opening for inserting the electric wire.

The present invention has been made to solve the above-mentioned problems of the conventional example, and eliminates twisting of parallel wires such as connector wires, and an electric wire tie that does not come off after inserting the electric wire from a split portion or a gap. It is intended to be provided.

[Means for solving the problem]

The present invention employs the following configuration to achieve the object.

That is, the wire tie of the present invention comprises an elastic engaging piece for attaching to a hole provided in a mounting panel on the outer peripheral surface of a synthetic resin cylinder having a flange, and splitting the outer peripheral surface along the axial direction. In the binder having the formed part, the tubular body is formed in a rectangular shape, and one of the two arms forming the split portion is formed to be rotatable up and down by a predetermined angle about its root when the wire is inserted. Then, a male portion is formed at the tip of the rotating arm, and a female portion is formed at the tip of the non-rotating arm to form the male portion and the female portion engageable with each other, and a lower portion of the male portion. Guide slopes inclined forward and backward in the axial direction of the cylinder are formed on the upper part of the female part so as to overlap each other, and the male part and the female part are guided by the guide slopes and relatively moved forward and backward in the axial direction of the cylinder. Are formed so as to engage with each other.

[Action]

Since the present invention has the above-mentioned configuration, the connector wire can be held in contact with a flat surface by forming the cylindrical body into a square shape, so that the wire will not be rounded and the connector wire will not rotate when inserting the wire. If the moving arm is pushed downward (inward), the tips of the two arms will be guided to the axially forward and backward guide slopes of the cylinder formed at each tip, and the cylinder will move forward and backward in the axial direction. Since it is formed so as to relatively move and engage with, the length of the engaging portion of the male portion and the female portion can be made large in the direction perpendicular to the axial direction of the tubular body.

〔Example〕

Hereinafter, embodiments will be described with reference to the drawings. First
FIG. 1 is a perspective view showing an embodiment of the present invention. FIG. 2 is a perspective view showing a usage state of the embodiment of the present invention. FIG. 3 is a plan view of FIG. 4 (A) to 4 (D) are explanatory views showing the engaging portion of the arm according to the embodiment of the present invention. First
As shown in FIG. 2, FIG. 3 and FIG. 3, reference numeral 15 is a synthetic resin rectangular cylinder having a flange 1, and is elastic for mounting in a square hole 16 provided in the mounting panel 4 on the outer peripheral surface. Engaging piece
17 and 17 are provided, and a split portion 20 composed of two arms 18 and 19 is formed on one surface of the outer peripheral surface on which the elastic engagement piece 17 is not provided. One of the two arms 18 and 19 is formed so as to be rotatable up and down by a predetermined angle about its root, and a male portion 21 is provided at the tip of the rotating arm 18 so that it does not rotate. The female part 22 is provided at the tip of the arm 19 of the
22 are formed so as to engage with each other. Guide slopes 23, 24 are formed on the lower part of the male part 21 and the upper part of the female part 22 so as to be inclined back and forth in the axial direction so as to overlap each other.

The wire tie of the embodiment of the present invention is formed of a synthetic resin (for example, polyamide) having appropriate elasticity and hardness.

Next, a method of using the wire tie according to the embodiment of the present invention will be described. When inserting the electric wire from the split portion 20, when the electric wire is pressed from above the arm 18 near the split portion 20, the arm 18 rotates downward (inward) about the root thereof and reaches below the arm 19. After rotating to hold the electric wire inside the tubular body 15, the arm 18 rotates upward (outward) by the elastic restoring force, and the male part 21 of the arm 18 and the female part 22 of the arm 19 are engaged. To meet. This engagement is performed as shown in FIGS. 4 (a) to 4 (d). First, the arm 18 moves from the position shown in (a) to the lower part of the male part 21 of the arm 18 toward the upper part of the female part 22 of the arm 19, and subsequently, as shown in (b), the male part of the arm 18 moves. After the guide slope 23 below the part 21 and the guide slope 24 above the female part 22 of the arm 19 abut, the male part 21 of the arm 18 is relatively moved along the guide slope 24 as shown in (c). After the male part 21 of the arm 18 reaches below the female part 22 of the arm 19, the male part 21 of the arm 18 moves relatively axially forward by the elastic restoring force, and as shown in (d), Then, the engagement between the male portion 21 of the arm 18 and the female portion 22 of the arm 19 is completed.

The wire tie of the above embodiment is used by attaching it to the square hole 16 of the mounting panel 4 as shown in FIGS. 2 and 3, and as shown in FIG. It can also be used as a protector when passing an electric wire through the end of the. In this case, the wire tie can be attached to the mounting panel 4 in advance, and the wire can be held inside the tubular body 15 by pushing the wire from above the arm 18 during wiring. Since the male portion 21 of the arm 18 and the female portion 22 of the arm 19 engage with each other while holding the electric wire, the electric wire does not come off from the inside of the binding tool.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

Since the parallel wire such as the connector wire is not rounded by forming the cylindrical body in a rectangular shape, there is no fear of twisting the connector wire, etc. The waste of space can be reduced. Also, if the rotating arm is pushed downward (inward), the tips of the two arms are guided to the guide slopes that are inclined forward and backward in the axial direction of the tubular body formed at each distal end. Since it is formed so as to relatively move forward and backward in the direction of engagement, the length of the engaging part of the male part and the female part can be made large in the direction perpendicular to the axial direction of the cylindrical body. rear,
It is possible to provide a structure in which the electric wire located near the tip of the arm does not easily come off even when a strong force acts outward from the arm.
