Description

[Detailed description of the invention] The present invention is designed to transmit operating force by freely sliding the inner cable through the outer casing.The terminal of the outer casing of the control cable is attached to a fixed member such as a frame. The present invention relates to a terminal device that connects a terminal to a driving member or a driven member, respectively.

Conventionally, for example, the terminal on the clutch pedal side of the control cable for operating the clutch of a car was
A holding cylinder was fixed to the inside surface of a mounting hole made through the vehicle body's dash panel, and a cylindrical fitting fixed to the end of the outer casing was inserted through the mounting hole into the holding cylinder and screwed onto its outer periphery. The fixing position can be adjusted by attaching the nut to the engine compartment side surface of the doss panel, and the cushion that also serves as a seal fitted to the tip of the nut is tightly fitted into the holding tube to attach the cylindrical fitting to the holding tube. The cylindrical fitting was designed to be elastically held within the cylinder to prevent the cylindrical fitting from interfering with the holding cylinder and making noise due to vibrations transmitted from the engine, but the cylindrical fitting was used to adjust the fixed position. If the cushion is pulled out, it may curl up due to the frictional force with the inner surface of the holding cylinder and separate from the cylindrical fixture. This requires extremely careful assembly, which hinders the improvement of work efficiency. Ta.

Incidentally, if the tightening margin of the cushion is reduced, the ease of assembly can be improved, but the force for holding the cylindrical fixture and the vibration absorbing properties will be insufficient due to the frictional force with the holding cylinder.

The object of the present invention is to eliminate such drawbacks and provide a terminal device that is easy to assemble.

Hereinafter, one embodiment of the present invention will be described based on the attached drawings. As shown in FIGS. 1 and 2, a holding cylinder 3 is fixed by welding to one surface of a mounting hole 2 formed through a fixed plate 1. A cylindrical fitting 5 is fixed to the end of the outer casing 4 by caulking, and is made of synthetic rubber for sealing around the inner cable 12 protruding from the end to prevent water and dust from entering. A conical surface is formed by locking and fitting the seal boot 7 into a groove 6 formed on the outer periphery of the tip of the cylindrical fitting 5, and reducing the diameter of the outer periphery of the tip of the cylindrical fitting 5 toward the rear. 8, there is a tsuba 9 on the outer periphery of the large diameter end.
A thin-walled cylindrical cushion 13 made of synthetic rubber with a protrusion is fitted therein, and a nut 10 is screwed into a male thread 11 formed on the outer periphery of the cylindrical fixture 5, and the nut 10 is screwed into the mounting hole of the fixing plate 1. When the cylindrical fitting 5 is inserted into the holding cylinder 3 from the holder 2, the collar 9 at the tip of the cushion 13 that contacts the inner surface of the holding cylinder 3 is rotated backward in the insertion direction and inward, as shown in FIG. The inner cable 1 is rolled up, compressed between the smallest diameter part of the conical surface 8 and the holding cylinder 3, and slides on the inner surface thereof.
2 is connected to a driving member or a driven member (not shown) such as a clutch pedal, and when the cylindrical mount 5 is pulled back toward the mounting hole 2 to adjust the fixing position, the cushion 13 is closed as shown in FIG. is rotated in the opposite direction and rewound, and the tsuba 9 slides,
The frictional force is smaller than the state shown in FIG.

As specifically explained in the above embodiment,
In the control cable terminal device of the present invention, a cylindrical fitting is fixed to the terminal of the outer casing of a control cable in which an inner cable is slidably inserted into the outer casing, and the cylindrical fitting is fixed to a holding cylinder fixed to a fixing member. A fitting is inserted and attached so that the fixing position can be adjusted, and a cushion is fitted around the outer periphery of the cylindrical fitting to be interposed between the holding tube and the end of the inner cable is attached to the cylindrical fitting. and a terminal device for a control cable that protrudes from the holding cylinder and is connected to a driving member or a driven member, in which the outer periphery of the tip of the cylindrical fitting is formed into a conical surface whose diameter is reduced at the rear in the insertion direction; The thin-walled cylindrical cushion is fitted into the holding cylinder, and when the cylindrical fitting is inserted, the front end of the cushion in the insertion direction contacts the inner surface of the holding cylinder and is rolled inward. Even if the cushion is fitted to the inner surface of the holding cylinder with sufficient tightness during insertion, it will not roll over and separate from the cylindrical fitting when extracted, and the cylindrical mounting The tool can be held reliably and elastically in the holding cylinder, and the assembly work can be easily performed.
