Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an operating cable used for regulating the transmission speed of an engine of an automobile or the like.

BACKGROUND ART Conventionally, in the case of a remote-controlled transmission, the speed of a transmission in an automobile or the like has been controlled by operating a change lever or the like connected via an operating cable.

Therefore, regarding the conventional operation cable, the second
To explain with reference to the drawings, the operation cable 1' is formed of an operation inner cable 2' and an outer cable 3' that encloses this inner cable.

The main part of the outer cable 3' includes a spirally wound wire 4' in close contact with the wire 4' in a cylindrical shape due to the need for reinforcement and flexibility in wiring.

Furthermore, both ends of this outer cable are fitted into sockets 6' via sleeves 5', and bearings and waterproof materials are attached so that the inner cable 2' can slide thereon. Therefore, the operating cable 1' is attached and wired to a transmission case (not shown) and a cable type shift bracket (not shown) through a socket 6'.

In this operation cable 1', the inner cable 2' included in the outer cable 3' transmits the operation of the shift lever to the shift and change of the transmission, and at the same time eliminates noise from the engine and transmission. It was spreading inside the vehicle.

Problems that the invention aims to solve: However, since the operating cable was connected to the engine transmission, vibrations and noise generated around the engine and transmission were transmitted from the engine side of the operating cable, and The wire 4' of the cable 3' serves as a convenient transmitting material to the cable shift bracket in the passenger compartment, causing large vibrations or sounds to resonate and be induced in these parts, which is disadvantageous. It was hot.

Means for Solving the Problems The present invention provides an operating cable that remotely transmits the operation of a shift lever in an automobile, etc. to a transmission, and the present invention provides a spiral-shaped control cable that is the main part of an outer cable that includes an inner cable. A divided part is formed in the middle of the cylindrical wire where the wires are closely connected, and the gap created at this divided part is filled with the hanging resin layer covering the outer cable, and this divided part is A reinforcing connector is crimped onto the outer periphery of the outer cable near the part.

Function: An appropriate divided portion is formed in the middle of the cylindrical wire that forms the main part of the outer cable of the operating cable, and the gap created at the divided portion is filled with the hanging resin layer covering the outer cable. Furthermore, since a reinforcing connector is crimped to the outer periphery of the outer cable near the split part, vibrations and noise around the engine and transmission can be blocked at the split part without impairing the strength of the operating cable, preventing them from propagating into the passenger compartment. Never.

Embodiment Hereinafter, an operating cable as an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a partial sectional view of the operating cable, and 1 is an operating cable made of steel wire or the like. The inner cable 2 is coated with Teflon (registered trademark) on its inner surface, and its outer surface is coated with a resin layer.The main part of the inner cable 2 is a spirally wound wire 4 that is closely cylindrically connected to the outer cable 3. is included in.

Then, a divided part of an appropriate width is formed in the middle of this cylindrical wire that forms the main part of the outer cable 3, and the gap created at the divided part is caused by the drooping of the resin layer covering the outer cable 3. Filled.

Further, a reinforcing connector 5 having appropriate strength is crimped onto the outer periphery of the outer cable 3 near the divided portion.

With the above configuration, vibrations and noise around the engine and transmission are transmitted to the outer cable 3 of the operating cable 1 to the engine side socket etc. (see Figure 2), and to the wire 4 which forms the main part of the outer cable 3. It conveys. However, this outer cable has a divided part formed in the middle of the wire 4, and the resin layer covering the outer surface of the outer cable 3, which is filled in the gap between the divided parts and hangs down, causes vibrations and By providing noise vibration-proofing and sound-absorbing effects, it is possible to reliably block vibrations and noise from propagating into the vehicle interior beyond the dividing portion.

Furthermore, since the reinforcing connector 5 is crimped onto the outer periphery of the outer cable 3 at the divided portion, the conventional strength of the operating cable 1 can be sufficiently ensured without being impaired.

It goes without saying that this reinforcing connector 5 does not impair the flexibility of the operating cable 1.

Effects of the Invention As detailed above, the problem with the operating cable of the present invention is that the helical wire, which is the main part of the outer cable and transmits vibration and noise, forms a divided part in the middle, and the Since the gaps between the parts are filled with a hanging resin layer, vibrations and noise around the engine and transmission are reliably blocked, preventing them from propagating into the passenger compartment. Since the cable is supplemented with a reinforcing connector, it maintains the same strength and flexibility as conventional operating cables.
