ヤ等の高張力材料が通常使用されている。In order to transmit the rotation of a transmission of a vehicle or the like to a speedometer or the like, a meter cable is used in which a flexible rotating shaft is inserted into a conduit. Conventionally, the covering structure of this meter cable was to wind a narrow metal plate into a coil to form a hollow and flexible inner sheath, and a flexible rotating shaft was attached to the hollow part of the inner sheath. It is known that a fiber cable reinforcing material is braided on the outside of the cable, and a covering layer is formed by injection molding a resin such as molten synthetic rubber thereon. In this case, high tensile strength materials such as polyaramid fibers and wires are usually used as cable reinforcements.

トアップの原因ともなる。(Problem to be solved by the invention) However, in such conventional technology, since the reinforcing material and the coating resin are different, slippage occurs between the image materials when high tension is applied to the cable. , only the coating resin part stretches.Also, because the linear expansion coefficients of the painting materials are different, slippage occurs as above due to temperature changes around the meter cable, and the inner sheath and coating layer There was a problem in that the lengths of the wires were misaligned, making it difficult to use in areas where there are temperature changes.To solve this problem, multiple coating layers were stacked to increase the frictional resistance between each layer. Although there are some methods, the formation of the covering layer becomes complicated and causes an increase in cost.

The figure is a partially cutaway view showing a meter cable according to the present invention.
FIG. 2 is a sectional view taken along line A--A in FIG. 1. In these figures, l denotes an inner sheath, which is formed by winding a narrow metal plate into a coil shape so as to be hollow and flexible. Reference numeral 2 is a high tensile strength fiber braided into a net shape, which serves as a reinforcing material for the covering layer, and in the embodiment of the present invention, a structure comprising a large number of thin filaments of polyaramid fiber is used. Polyaramid fibers have excellent properties such as high tensile strength and not softening or melting even at high temperatures. As the reinforcing high tensile strength fibers, it is also possible to use fibers such as glass fibers and carbon fibers in addition to the polyaramid fibers. This polyaramid fiber 2 is
It is impregnated with another resin, for example, a hot-melt, strong adhesive resin such as a mixture of polypropylene and polyamide.
At the same time that the resin penetrates between the filaments and adheres to each other, a large number of resin lumps 3 are formed on the outside of the polyaramid fibers 2. In this way, the polyaramid fibers 2 impregnated with the branches (fat 3) are braided on the outside of the inner sheath 1 and set in a mold (not shown), and then a resin such as synthetic rubber molten with an extrusion molding machine is poured onto it. The polyaramid fibers 2 are sandwiched between the inner sheath 1 and the synthetic rubber, and are injected to form the outer sheath N4.The polyaramid fibers 2 not only bite into the synthetic rubber outer sheath N4, but also inject the resin and the resin impregnated into the polyaramid fibers 2. , the resin mass 3 is melted again, and the polyaramid fibers 2 and the covering layer 4 are bonded and integrated.The melted adhesive resin 3 also permeates between the covering layer 4 and the inner sheath 1 at the same time, bonding them together. Fix with adhesive.

造とすることができる。In this way, since the polyaramid fiber 2 as a reinforcing material and the outer coating layer 4 are bonded, the polyaramid fiber 2 compensates for the weaknesses such as thermal expansion and tensile strength of the resin forming the coating N4, and is resistant to temperature changes and tensile strength. A strong cable sheathing structure can be achieved.

る。According to the embodiments of the present invention, compared to the case where the conventional reinforcing material and the outer coating layer are not bonded,
The expansion and contraction of the meter cable outer coating layer was 0.8% in the longitudinal direction with respect to the temperature change in C.2, but by implementing the present invention, the expansion and contraction in the longitudinal direction was reduced to 0.2% or less, even in locations with large temperature changes. Now it can be used stably. Furthermore, compared to the case where a wire is used as the reinforcing material, the one using the polyaramid fiber 2 has better vibration absorption, so the -3 dBJ attenuation rate is improved for vibrations of 0 to 5 kHz.
さらに同様の理由から、防音性も５ｄＢ向−ヒした。Furthermore, for the same reason, the soundproofing properties were also increased by 5 dB.

Therefore, it is possible to obtain a meter cable covering structure that has little expansion and contraction due to temperature changes, high tensile strength, and high vibration sound attenuation. Furthermore, there is no need to stack a large number of coating layers, making it possible to reduce costs.
