Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an assembly structure for control cables for remotely controlling various devices.

(Prior Art) Conventionally, in the assembly structure of this type of control cable, as shown in FIG.
This was fixed by tightening it with a nut e.
For this reason, the assembly work was performed with both hands, and in a layout where there were adjacent parts, a tightening tool could not be used, which not only resulted in poor work efficiency, but also caused a risk of failure due to insufficient tightening. As an alternative to this, Japanese Utility Model Application Publication No. 55-137712 discloses a structure in which a locking force biasing spring is molded into a single piece in the outer casing underframe locking fitting, but in this structure, the flange and attachment Since the underframe is simply clamped between springs and the load is received by the springs, there is a risk that the underframe may come off when subjected to vibrations, shocks, etc., and since the spring and the retaining metal fittings are integrated, the spring may become heated. causes history,
In addition to reducing the elastic effect, since the biasing spring is integrally molded into the fastening metal fitting, there are problems such as high cost and the risk of the spring falling off.

(Problem to be solved by the invention) Therefore, this invention was an attempt to solve the above problems, and to obtain an inexpensive control cable assembly structure that is easy to assemble and can be installed reliably and robustly. That is.

(Means for Solving the Problem) As a means for achieving this, this invention attaches an elastic body to a mounting portion opening on the side of a bracket that is inserted and locked between flanges provided on a control cable mounting tool. The elastic body constitutes legs that protrude toward the inside of the insertion port from both sides to narrow the insertion port by elasticity, and also includes a wave-shaped spring portion extending horizontally to the mounting portion at the end periphery. An annular portion is formed, and the tips of the leg portions provided at both ends of the annular portion are fitted and supported in recesses provided on both sides of the insertion opening, and the engagement surface between the mounting tool and the bracket is formed by the elastic body. The control cable has a structure in which the control cable is elastically engaged and held in the upper, lower, left and right directions.

(Function) Since this method is used, when the control cable mounting tool is inserted into the insertion opening of the mounting part of the bracket, the elastic body is expanded and fitted into the mounting part, and the flange of the mounting tool and the bracket are connected. A locking surface is formed by an elastic body on the surface facing the bracket, and the elastic body of the insertion port is also narrowed again to form a locking surface, so that the mounting tool is elastically retained on the bracket from top to bottom and left and right. be done. In addition, both ends of the annular portion of the elastic body constitute legs, and the tips of the legs fit into the recessed portions of the bracket due to their elasticity, so even when the mounting tool is not fitted into the insertion opening, the left and right direction of the elastic body can be adjusted. This prevents rattling and prevents the elastic body from falling off the flange unnecessarily.

(Example) An example of a specific configuration of this invention shown in the drawings will be described in detail below.

Reference numeral 1 denotes a bracket, which is bent into an L shape, for example, and fixes the vertical plate 2 to the fuselage. In addition, a fitting hole 4 which is a mounting part is bored in the horizontal plate 3, and
An insertion port 5 communicating with the fitting hole 4 is opened toward the side. This insertion port 5 has concave portions 6, 6 formed on both sides near the outer end, and a width is formed between the concave portions 6 and the fitting hole 4 toward the fitting hole 4. Slanted edges 7, 7 are formed on both sides. Reference numeral 8 is an elastic body in the form of a leaf spring, and guiding legs 10, 10 are provided at both ends of a notched circular fitting part 9, respectively, and the fitting part 9 has its upper surface bent by pressing. An annular portion 11 is formed, and a wavy spring portion 12 is formed in the annular portion 11. The leg portion 10 is disposed along the recessed portion 6 and the inclined edge 7, and the fitting portion 9 is fitted into the fitting hole 4 so that the annular portion 11 is brought into contact with the upper peripheral surface of the fitting hole 4. Attach the elastic body 8 to the bracket 1.
Reference numeral 13 denotes a mounting tool for the control cable 14, through which the control cable 14 is inserted, and flanges 16a and 16b are formed on the outer periphery of the fitting part 15 at the upper and lower sides, respectively.

With this structure, in order to attach the mounting tool 13 to the bracket 1, the insertion part 15 of the mounting tool 13 is inserted into the insertion opening 5 of the bracket 1. As a result, the legs 10, 10 of the elastic body 8 disposed along the inclined edge 7 of the insertion port 5 are pushed apart against the elasticity, and the mounting tool 13 is inserted into the fitting hole 4. The lower flange 16b is in contact with the lower surface of the bracket 1, while the upper flange 16a is in contact with the elastic body 8.
The spring portion 12 of the annular portion 11 is pressed against the spring portion 12 in the vertical direction, and the fitting portion 9 elastically attaches the insertion portion 15 from the left and right so as to reduce its diameter. At the same time, the legs 10, 10 also move inward to narrow the distance between them to prevent the fitting part 15 from coming off laterally from the fitting hole 4, thereby preventing the fitting part 15 from coming off laterally from the fitting hole 4. 13 is securely fixed to the bracket 1.

In addition, when removing the mounting tool 13 from the bracket 1, insert a tool such as a screwdriver through the insertion port 5,
The mounting tool 13 can be removed from the bracket 1 by pushing out the legs 10 of the elastic body 8 to enlarge the diameter of the fitting portion and pulling the mounting tool 13 toward the insertion port 5.

(Effects of the invention) As described above, in this invention, the elastic body is simply fitted into the fitting hole and the insertion opening of the bracket, and the leg ends are fitted into the recessed parts. Not only can you save the trouble of installing the
There is no risk that the elastic body will fall off from the fitting part. In addition, the mounting tool can be easily installed by simply pushing it through the insertion port against its elasticity, and the assembly process does not require any special tightening work, and can be quickly assembled with one hand. It can be reliably assembled even in locations with rough layouts. Furthermore, after assembly, the mounting tool firmly clamps the bracket between the flanges of the mounting tool in the vertical direction by the horizontally extending wave-shaped spring portion of the elastic body, and its legs protrude into the insertion slot, allowing the fitting to fit into the mounting tool. By reducing the diameter of the joining part, the fitting part of the fitting is elastically clamped, so it will not come off even if the bracket or fitting is subjected to external forces in the vertical and horizontal directions, such as vibrations and shocks. It has various advantages, such as being able to be fixed firmly and reliably without any problems, and since the spring and mounting device are separate, there is no reduction in the elastic effect, and the structure is simple and can be manufactured at low cost. It has the following effects.
