DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control cable terminal fixing device for fixing a terminal of an outer casing of a control cable in which an inner cable is slidably inserted into an outer casing to a mounting plate.

[0002]

2. Description of the Related Art In a conventional control cable terminal fixing device, an attachment hole is formed by reducing the diameter of a plurality of claw pieces which are circumferentially divided with respect to the attachment hole by elastic deformation. Although it was designed to pass through and fixed to the mounting plate, if the nail pieces were thinned to make assembly easier, the strength decreased, and if the nail pieces were thickened to increase the strength, it must be assembled with a large force. There was a problem that did not become.

[0003] Further, in the case of adopting a structure in which an anti-vibration rubber is inserted between the outer casing and the mounting member in order to block transmission of vibration between the cable and the mounting plate, after the rubber is molded, the outer side of the rubber is molded. There is a technical problem in that injection molding must be performed at a low pressure so that rubber is not compressed when the mounting member is injection molded.

Means for Solving the Problems, Actions and Effects As means for solving such problems, the invention according to claim 1 is characterized in that an end of an outer casing is provided with an abutment plate, an abutment plate and an axial direction. A plurality of projections extending radially at an interval on the front side of the base and a coupling member comprising projections formed on at least one rear surface of the plurality of projections, and a radial escape groove through which the projections pass is provided on the mounting plate. And a mounting hole having a recess formed between the clearance grooves so as to be fitted with the protrusion, wherein the protrusion is aligned with the clearance groove and the abutment plate is pressed against the mounting plate. When turned by a predetermined angle in the contact state, the mounting plate is sandwiched between the protruding portion and the abutment plate, and the projection is fitted into the concave portion and rotation is prevented, so that the outer tube is attached to the mounting plate. It can be fixed firmly with a small force.

According to the second aspect of the present invention, the connecting member is formed separately from the outer casing, and the small-diameter cylindrical body integrally formed on the rear surface of the connecting member can be fitted into the large-diameter cylindrical body integrally formed on the outer casing. In addition, since the projection formed on the outer periphery of the small-diameter cylindrical body is fitted into the hook-shaped groove formed on the large-diameter cylindrical body, the coupling member does not easily come off the mounting plate.

According to the third aspect of the present invention, since the locking groove is continuously provided at the deep end of the hook-shaped groove, the protruding piece is engaged with the locking groove, and the connecting member is securely fixed by the mounting plate.

According to the invention of claim 4, since a cushion with a flange is interposed between the small-diameter cylinder and the large-diameter cylinder, the cushion can be assembled without applying a large pressure to the cushion. Vibration transmission between the motor and the mounting plate can be reliably shut off.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings. In the drawing, reference numeral 1 denotes a control cable in which an inner cable 3 is slidably inserted into an outer casing 2, a large-diameter cylindrical body 4 is fixed to a terminal of the outer casing 2, and a terminal fitting is attached to a terminal of the inner cable 3. 5 is fixed.

As shown in FIG. 2, the large-diameter cylindrical body 4 has a hook-shaped groove 6 cut in the axial direction from the open end thereof and then cut in the circumferential direction. A cut groove 7 is formed.

Similarly, as shown in FIG. 2, reference numeral 8 denotes a connecting member, on the rear surface of which a small-diameter cylindrical body 9 is integrally formed.

The connecting member 8 comprises an abutment plate 10 and three projecting portions 11 spaced at the front side thereof.
A projection 12 is formed on the rear surface of the individual.

As shown in FIG. 3, reference numeral 13 denotes a rubber cushion comprising a cylindrical portion 14 and a flange portion 15. As shown in FIG. 4, the cylindrical portion 14 is fitted to the small-diameter cylindrical body 9 of the connecting member 8. The flange 15 is brought into contact with the rear surface of the abutment plate 10.

On the outer periphery of the small-diameter cylindrical portion 9, a front surface is provided with a locking surface 17.
4 and 5, the projecting piece 16 is aligned with the hook-shaped groove 6 of the large-diameter tubular body 4 and the small-diameter tubular body 9 of the coupling member 8 is pushed in as shown in FIGS. When the cylindrical portion 14 of the cushion 13 is tightly fitted into the large-diameter cylindrical body 4 and the protruding piece 16 abuts on the inner end of the hook-shaped groove 6 in the axial direction, the protruding piece is rotated by a relatively small angle. Reference numeral 16 corresponds to the innermost end of the hook-shaped groove 6 in the circumferential direction.

At this time, since the flange portion 15 of the cushion 13 is elastically compressed by the end surface of the large-sized cylinder 4, when the assembling force is reduced, the large-diameter cylinder 4 and the coupling member 8 are separated from each other by the reaction force. The projecting piece 16 fits into the locking groove 7 and the connecting member 8 is firmly connected to the large-diameter cylindrical body 4.

As shown in FIG. 2, reference numeral 20 denotes a mounting plate, in which three relief grooves 21 and concave portions 22 are formed around mounting holes 23 at equal angular intervals.

After the three protrusions 11 of the connecting member 8 are aligned with the clearance grooves 21 and the connecting member 8 is pressed against the mounting plate 20 and then turned by 60 °, the protrusions on the rear surface of the protrusion 11 are formed. The fitting of the coupling member 8 to the mounting plate 20 is fixed to the mounting plate 20 so that the coupling member 8 cannot rotate and cannot move in the axial direction.

In the above, when the vibration proof property is not required, the cushion 13 may be removed and the small-diameter cylinder 9 may be fitted tightly to the large-diameter cylinder. It may be integrated with the large-diameter cylinder 4.
