Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wire binding member used for fixing a wire for a turn signal switch or the like mounted on a steering post of an automobile.
[0002]
[Prior art]
A conventional technique of this type of member will be described with reference to FIGS. 4 to 6 by taking a wire binding member for a turn signal switch of an automobile as an example.
[0003]
4 (a) and 4 (b), reference numeral 1 denotes a turn signal switch. A coupler 3 is connected to the wire 2 drawn from the switch, and is fastened and fixed to the steering post 4 with screws (not shown).
[0004]
Reference numeral 5 denotes a wire binding member made of molded resin, which is fixed by inserting two protrusions 4A of the steering post 4 into mounting cuts 5A provided at both ends.
[0005]
FIG. 5 is a perspective view for explaining a method of accommodating and binding the wire 2 in the wire binding member 5. After the wire 2 is accommodated in the wire accommodating recess composed of the substrate portion 5 </ b> B and the left and right support columns 5 </ b> C and 5 </ b> D, An arm portion 5F, which is foldable at the tip of the column portion 5D via a thin hinge portion 5E, is tilted toward the other column portion 5C to hold down the wire 2 from above, and an opening at the tip of the arm portion 5F The 5G is fixed by being hooked on the elastic claw 5H at the tip of the other column portion 5C.
[0006]
The function of the wire binding member 5 is to stop the wire 2 on the side opposite to the driver of the steering post 4 so that the wire 2 does not come out to the driver side of the steering post 4 and interfere with the driving operation. In particular, those equipped with a tilt function capable of adjusting the direction of the steering 6 to an angle at which the driver can easily operate the steering post 4 can be bent at a fulcrum 4B shown in FIG. This wire binding member 5 is required in order to prevent the steering post 2 from being pulled or loosened and coming out to the right side (driver side) of the steering post 4.
[0007]
[Problems to be solved by the invention]
However, in the conventional wire binding member 5, since the area of the wire accommodating portion is constant, when the functions of the turn signal switch 1 and the like are different and the number of the wires 2 is also different, the wire 2 is securely bound and held. However, a separate wire binding member 5 is required for each functional variation of the turn signal switch 1 and the like, and a large number of molding dies are required, and there is a problem in that a loss occurs in terms of management.
[0008]
This invention solves such a conventional subject, and it aims at providing the wire binding member which can be shared also with respect to the wire from which a number differs.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention integrally forms a cantilever-like tongue-shaped portion extending in the entire region between the support column portions and having elasticity in the vertical direction on the substrate portion of the wire receiving recess, and is arranged in a row in the wire receiving recess. Alternatively, even when accommodating different numbers of wires in two rows, the wires are configured to be clamped and bound between the arm portion and the cantilevered tongue-like portion with a constant pressure .
[0010]
Thereby, even if the number of wires to be bundled is different, it is possible to provide a wire bundling member that can be reliably bundled and held.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, there is provided a substrate portion provided with struts at both ends , a wire accommodating recess formed between the substrate portion and the strut portion, and a hinge portion at the tip of one strut portion. an arm portion provided so as to be folded, Ri Do resilient pawl provided at the tip of the other strut to engage the opening of the arm tip, said substrate portion of said wire receiving recess, For the case where a cantilever-like tongue-shaped portion extending in the whole area between the strut portions and having elasticity in the vertical direction is integrally formed, and different numbers of wires are accommodated in one or two rows in the wire accommodating recess. However, the wire is a molded resin wire binding member configured to be clamped and bound between the arm portion and the cantilevered tongue portion with a constant pressure, and is bound by the wire binding member. Different number of wires Even, an effect that can be reliably bundling and holding.
[0012]
According to a second aspect of the present invention, in the first aspect of the present invention, a linear concavo-convex portion in a direction connecting the support columns is provided on at least one of the upper surface of the tongue-shaped portion and the lower surface of the arm portion that sandwich the wire. Thus, the wire after being bundled is difficult to move particularly in the length direction, and the wire can be held more firmly.
[0013]
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 by taking a wire binding member used for a turn signal switch of an automobile as an example.
[0014]
(Embodiment 1)
FIG. 1 is a perspective view for explaining a method of housing and binding wires 12 in a wire binding member 11 according to the first embodiment of the present invention. In FIG. The substrate portion 11B of the wire receiving recess composed of the support columns 11C and 11D has a tongue-like portion 11I that extends across the entire area between the support columns 11C and 11D at both ends and has elasticity in the vertical direction. After the accommodated wire 12 is placed on the tongue-like portion 11I, the arm portion 11F provided via the thin hinge portion 11E at the tip of one of the supporting column portions 11D is connected to the other supporting column portion, as in the conventional example. Tilt to the 11C side, hold down the wire 12 from above, and fix it by hooking the opening 11G at the tip of the arm 11F to the elastic claw 11H at the tip of the other column 11C.
[0015]
When pressing the wire 12 from above with the arm portion 11F, the lower tongue portion 11I of the wire 12 is pushed downward to be bent slightly, and the wire 12 is between the arm portion 11F and the tongue portion 11I. It will be in the state of being clamped and bound at a constant pressure.
[0016]
FIG. 2 (a-1) shows a front view of the state in which the wires 12 are bundled in a row with the wire bundling member 11 of the first embodiment by bending the tongue-like portion 11I due to elasticity, and FIG. FIG. 2 (a-2) shows a front view in a state of being bound in the same two rows in FIG. 2 (b-1), and FIG.
[0017]
(Embodiment 2)
FIG. 3 is a perspective view for explaining a method of accommodating and binding the wire 12 in the wire binding member 13 according to the second embodiment of the present invention, in which the same wire as that of the first embodiment is shown. On the upper surface of the tongue-shaped portion 13I of the substrate portion 13B of the housing recess, a linear uneven portion 13J in the direction connecting the support columns 13C and 13D at both ends is provided, and the wire 12 housed in the wire housing recess is The linear concavo-convex portion 13J and the arm portion 13F are sandwiched and bound.
[0018]
Accordingly, the bundled wires 12 are difficult to move particularly in the length direction and can be held more firmly.
[0019]
In the above description, the case where the linear concavo-convex portion 13J is provided only on the upper surface of the tongue-like portion 13I of the substrate portion 13B is shown, but this may be provided on the lower surface of the arm portion 13F, and the tongue-like portion 13I. Needless to say, it may be provided on both the upper surface and the lower surface of the arm portion 13F.
[0020]
【The invention's effect】
As described above, according to the present invention, it is possible to realize a wire bundling member that can be used in common for different numbers of wires, and can be securely bundled and held, thereby reducing the cost of the mold and reducing the management loss. The effect that it can reduce is acquired.
