Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to, for example, a control cable that connects various doors and control levers of an automobile air conditioner and transmits the operation of the control lever to each door.

(Technical background) In general, this type of cable 1 is constructed by slidably inserting an inner cable 1b made of steel or the like into an outer cable 1a made of synthetic resin, as shown in FIG. The inner cable 1b is given flexibility and is wired along arbitrary routes to various parts of the automobile, and both ends of the outer cable 1a are fixed to an arbitrary board 2 with clips 3 having bent pieces 3a. A movement guide path is defined, and one end of the inner cable 1b is connected to a control lever, and the other end is connected to various doors. Note that 3c in the figure is a locking claw.

Conventionally, this type of cable 1 is attached to various doors by winding the end of the control cable 1 into a coil to form a coil portion 4, as shown in FIGS. 1 and 2. 4 is fitted onto a pin 6 on the lever 5 side.

(Problems with the prior art) However, with the above-mentioned mounting means, so-called play is unavoidable between the coil portion 4 and the pin 6, and as a result, it is somewhat inferior in terms of reliable transmission of the lever operation force, and this This has the disadvantage that the control cable comes off from the pin 6 when assembling the vehicle body, delaying assembly work. Therefore, recently, as shown in Fig. 3, an E-ring 7 is fitted to the tip of the pin 6 to prevent it from coming loose, or as shown in Fig. 4, the tip of the pin 6 is bent after fitting the coil part 4. Measures are being taken to prevent them from falling off. As a result, not only is the work of attaching the cable 1 to the pin 6 troublesome, but also there are problems such as the need for extra parts.

(Purpose of the invention) The present invention was made with the aim of improving the above-mentioned conventional problems, and it is possible to securely attach the end of the cable without using any extra parts or processes. The present invention provides a cable end attachment device that allows for

(Example) Next, an example of the present invention will be explained as shown in Figs. 5 to 8.
The same reference numerals are used to describe the same members as in FIGS.

As shown in FIG. 5, the axis A-A of the coil portion 8, which is connected to the end of the cable 1 and is wound into a coil, is inclined by a required angle α with respect to the axis of the cable 1b. . This angle of inclination is set to a value such that the distance L between the inner peripheral portions of the upper and lower ends that enters the inside of the coil portion 8 is smaller than the diameter of the pin 6.

Therefore, when fitting the coil part 8 to the pin 6, as shown in FIG. If it is raised perpendicular to the axis B-B of the pin 6, the axis A-A of the coil part 8 will be inclined with respect to the axis B-B of the pin 6, as shown in Figure 7, so that it will enter inside the coil part 8. The inner periphery of the upper and lower ends that have come out is pressed against the outer periphery of the pin 6, and a large frictional force is generated locally in the area, restricting movement in the axial direction and preventing it from loosening and slipping out. .

FIG. 8 shows that grooves 9, 9 are formed in advance on the outer periphery of the pin 6 in correspondence with the upper and lower end portions of the coil portion, in order to ensure the above-mentioned slip-off prevention effect.
The upper and lower ends of the coil portion 8 are fitted into the coil portion 8 to reliably prevent movement in the axial direction.

(Effects of the invention) As described above, the present invention provides a control cable in which a coil part is connected to the end of the control cable, and this coil part is fitted to a pin of a lever, etc., and the axis of the coil part is connected to the cable. The inner circumference of the upper and lower ends of this coil part is crimped to the outer circumferential surface of the pin to prevent it from coming off, so that the coil part at the end of the cable can be fitted to the pin on the mounting side. It can be prevented from coming off by simply fitting it together, and therefore there is no need to use retaining members such as E-rings or bending of pins as required in the past, making it extremely easy to attach the cable end. You can get the same effect.
