Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a twisted-wire wiring tube, and more particularly to a twisted-wire wiring tube that can protect a twisted wire used in a hybrid car that uses both power and gasoline as a power source from the outside.
[0002]
[Prior art]
Recently, a hybrid car that uses both power and gasoline as a power source uses a large-capacity battery and increases the number of electrical components compared to gasoline vehicles. When connecting, it is necessary to prevent the generation of noise. In particular, in the case of a thick cable or the like wired from a large capacity battery to an electrical component, the generation of noise is suppressed by twisting the thick cable.
[0003]
By the way, in the case of wire harnesses and electric cables, in order to prevent damage caused by contact with body panels and electrical components, wiring pipes such as corrugated pipes are attached to the outer periphery to protect them. FIG. 3 shows an example of such an aspect.
[0004]
In FIG. 3, reference numeral 1 denotes a corrugated tube, and a twisted wire 2 made of a thick cable (about 15 cm ² ) is accommodated in the inner peripheral portion of the corrugated tube 1, and this twisted wire 2 is a tape 3 indicated by diagonal lines. By being wound, untwisting is prevented. That is, since the thick cable has higher rigidity (stronger stiffness) than the thin cable, the pair of thick cables constituting the twisted wire will be untwisted. ing.
[0005]
[Problems to be solved by the invention]
However, in the conventional corrugated pipe 1 of this type, the tape 3 is wound and held around the twisted wire 2, so that a tape winding operation occurs, and the twisted wire 2 is attached to the corrugated pipe 1. In addition to the poor workability of the work to be mounted, there is a problem that the cost of the twisted wire increases as much as the tape is used.
[0006]
Therefore, the present invention can easily prevent twisting of the twisted wire without using a tape, can improve the workability of the twisted wire mounting work, and reduce the cost of the twisted wire. An object of the present invention is to provide a twisted wire conduit.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is a wiring tube for wiring a twisted wire in which a pair of electric cables is twisted, and a pressing member is disposed at a constant interval inside the wiring tube. It is characterized in that a slit having the same width as the diameter of the electric wire cable is formed in the holding member so that the twisted wire can be inserted therethrough.
[0008]
In that case, the twisted wire can be inserted through the slits of the presser member installed at regular intervals and fixed to the presser member, so that twisting of the twisted wire can be easily prevented without using tape. it can. For this reason, the workability of the work of attaching the twisted wire can be improved and the cost of the twisted wire can be reduced.
[0009]
In order to solve the above-mentioned problem, the invention according to claim 2 is characterized in that, in the invention according to claim 1, the pressing member is arranged at a constant interval with respect to the pitch of the twisted portion of the twisted wire. The twisted portion of the twisted wire is inserted into the wire.
[0010]
In that case, it is possible to reliably prevent the twisted wire from being untwisted by inserting the twisted portion, which is the place where the twisting occurs, into the slit of the holding member, and to manage the pitch-to-pitch dimensions of the twisted wire. It can be done easily.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is a view showing an embodiment of a twisted-wire wiring pipe according to the present invention, and shows an example in which a corrugated pipe is used as the wiring pipe. The wiring pipe is not limited to a corrugated pipe but may be a protector, a tube, or the like.
[0013]
First, the configuration will be described. 1 and 2, a pair of electric wires 11 and 12 are twisted twisted wires 13, and the twisted wires 13 are attached to a corrugated tube (wiring tube) 14.
[0014]
A holding member 15 is provided on the inner peripheral portion of the corrugated tube 14, and the wiring tube 15 is spaced at a constant interval with respect to the pitch of the twisted portion of the twisted wire 13. In this embodiment, the interval is twice the pitch P. It is arranged by.
[0015]
Further, a trifurcated slit 15a is formed in the holding member 14, and this slit 15a has a width substantially the same as the diameter of the electric cables 11 and 12. The slit 15a is open at the upper end a, and the twisted wire 13 is inserted from the upper end a into the slit 15a.
[0016]
The twisted wires 13 inserted through the slits 15a are twisted portions, and the twisted wires 13 shown in FIGS. 1 and 2 are largely separated from each other, but this is to emphasize the twisted portions. It goes without saying that the wires are in close contact with each other as is well known.
[0017]
In order to attach the twisted wire 13 to the corrugated tube 14 having such a configuration, the twisted portion of the twisted wire 13 can be easily fixed to the presser member 15 by inserting it into the slit 15a from the upper end portion a. Twisting of the twisted wire 13 can be easily prevented without using a tape. For this reason, the workability of the installation work of the twist wire 13 can be improved, and the cost of the twist wire can be reduced.
[0018]
Further, the twisted wire 13 can be reliably prevented from being untwisted by inserting the twisted portion where the untwisting occurs into the slit 15a of the holding member 15 and the pitch between the twisted wires 13 can be prevented. Can be easily managed.
[0019]
【The invention's effect】
According to the first aspect of the present invention, the twisted wire can be inserted into the slit of the presser member installed at regular intervals and fixed to the presser member. Can be easily prevented. For this reason, the workability of the work of attaching the twisted wire can be improved and the cost of the twisted wire can be reduced.
[0020]
According to the second aspect of the present invention, it is possible to reliably prevent the twisted wire from being untwisted by inserting the twisted portion, which is a portion where the untwisting is generated, into the slit of the holding member, and to twist the twisted wire. It is possible to easily manage the pitch dimension.
