Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a mounting device for an electrical component, which has a structure in which an electrical component having a mounting arm, such as a timer, is mounted by rotating it along a mounting member.

Devices of this kind can be seen in the past, for example, in the installation of timers in the operating box of washing machines.

For washing machines, the timer was previously attached to the front panel of the control box with multiple screws.
In recent years, in order to simplify the work, an L-shaped elastic claw with one end fixed integrally and the other end free has been installed on the back of the front panel, and the timer mounting arm can be attached to the elastic claw by rotating the timer. It is designed to be installed in a state where it is engaged and prevented from coming off.

However, in this device, the elastic claw is elastically deformed so that when it comes into sliding contact with the timer mounting arm, it is pressed by the arm and rotates around one end integrated with the front panel. Due to the restoration after sliding contact, the surface that locks the timer's mounting arm must also be shaped like an arc or a chord-like inclined surface with one end as the center. Since the structure was such that they were only in contact with each other, there was a drawback that it was not possible to securely prevent them from coming out.

Therefore, the present invention provides an electrical component mounting device that can prevent the mounting arm of the electrical component from being pulled out over the entire surface, can obtain a similar and very solid retaining effect, and does not require much force for operation. It is intended for this purpose.

An embodiment in which the present invention is applied to the installation of a timer in the operating box of a washing machine will be described below with reference to FIGS. 1 to 6.

First, in Fig. 1, 1 is the washing tub flange 3 on the outer box 2.
This is an operation box base with a curved cross section placed on the base, and is made of, for example, synthetic resin.A front panel 4 of the operation box also made of synthetic resin is bonded to this, and an operation box 5 is constructed in a similar manner. There is.

The front panel 4 is a mounting member for a timer 6, which is an electrical component, and has a cylindrical hole 7 protruding toward the front surface at the center of the timer mounting portion. It has a timer receiver 8 projecting from the back side.

Reference numeral 9 denotes a hole formed in a relatively wide area in both the upper and lower parts of the timer receiver 8 of the front panel 4, and the elastic deformation member 10 is provided above and below the hole. Holes 11 are formed in a wider area than the holes 9 above and below, respectively.

More specifically, each of the elastically deformable members 10 is provided in the form of a bridge with both ends integrally fixed in the area between the holes 9 and 11 of the front panel 4, as shown in FIG. A locking portion 13 is provided on the outer periphery of the timer 6, into which two mounting arms 12 formed symmetrically and projecting are fitted.

This locking part 13 is attached to a support wall 14 provided at the upper part of the upper part of the elastic deformable member 10 and at the lower part of the elastic deformable member 10 so as to protrude toward the back side. The locking walls 15 having an inverted-shaped cross section and an inverted-shaped cross section as shown in FIG. A hook 18 is formed at the tip of each of the hooks 18, with an inward surface 16 having a straight shape and an outward surface 17 having a diagonal shape.

Incidentally, reference numeral 19 in the figure is a hole for punching out the locking wall 15.

Next, the operation of this embodiment configured as described above will be described.
First, before the front panel 4 is assembled to the base 1, the timer 6 is placed in the state shown by the two-dot chain line in FIG. Both mounting arms 12 face the outward surface 17 of the hook 18 as shown in FIG. 12 is the outward facing surface 1 of the hook 18
7 and lifts up the entire elastic deformable member 10 including the locking portion 13 and elastically deforms the elastic deformable member 10 in an arched manner as shown in FIGS. It passes through the side opening of the locking part 13.

When the attachment arm 12 of the timer 6 passes through the lower surface of the hook 18, the elastic deformation member 10 immediately restores its original shape, and the attachment arm 12 of the timer 6 is attached to the locking portion 13 by the restoring force of the elastic deformation member 10. As shown in FIG. 6, the timer 6 is fitted to the front panel 4, and the mounting arm 12 of the timer 6 is prevented from coming out, thereby fixing the timer 6 to the front panel 4.

Incidentally, the forward movement of the timer 6 mounted in this way is stopped by the aforementioned timer receiver 8, the backward movement is stopped by the locking part 13, and the movement in the turning direction is also stopped by the locking part 13. Therefore, it is possible to obtain a secure fixation state in which no so-called rattling occurs in all directions.

In this embodiment, the elastically deformable member 10, which is lifted by the mounting arm 12 slidingly contacting the outward surface 17 of the hook 18 when the timer 6 is mounted, has both ends integrally fixed to the front panel 4. Therefore, unlike a conventional simple elastic claw with only one end fixed, the deformation when lifted is not a rotation but a linear movement in which the locking part 13 is moved straight upward, so that the timer 6 The surface that locks the mounting arm 12 to prevent it from coming off, that is, the inward surface 16 of the hook 18, can also be formed into a straight shape as described above, and the entire surface can be brought into contact with the mounting arm 12. , a reliable slip-out prevention effect can be obtained over a wide area.

In addition, in order to obtain a reliable retaining effect with conventional simple elastic claws, the elastic claws must have a certain level of rigidity. While there was a concern that force was required and the work was difficult, in the present embodiment described above, such a need is not required and the span of the elastically deformable member 10 can be secured for a long time, resulting in a richer work environment. Since it has good elasticity, the timer 6 can be easily installed without requiring much force.

Furthermore, in this embodiment, after the above-mentioned installation, especially before the front panel 4 is assembled to the base 1, an external force is applied to the timer 6 from the same direction as when it is installed, that is, an external force opposite to the above-mentioned operating force. Even if an external force is applied from any direction, the elastically deformable member 10 will not be elastically deformed, and of course the timer 6 will not be elastically deformed, so the mounted state of the timer 6 can be maintained firmly. Disconnection of other electrical components such as lead wires to the timer 6 can also be prevented, and electrical reliability can also be improved.

Now, FIG. 7 to FIG. 12 respectively show different embodiments of the present invention, among which FIG. 7 and FIG. 9 and 10, a timer presser 22 is formed apart from this and above it by extending from the back surface of the front panel 4 to elastically deform the elastically deformable member 10 downward.
11 and 11 show a structure in which a locking portion 23 having a double claw structure similar to that described above is provided on the lower surface of an elastically deformable member 10, and the elastically deformable member 10 also functions as the timer presser 22. In FIG. 12, a locking portion 24 formed from a hemispherical projection is provided on the upper surface of the elastically deformable member 10, and a hole 25 formed in the mounting arm 12 of the timer 6 is fitted into the locking portion 24. A replacement timer presser 26 is provided to cause the elastically deformable member 10 to elastically deform downward, but the rest is the same as described above, and all the same effects as described above can be obtained.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the invention, such as application to applications other than washing machines, for example.

As explained above, the present invention provides a bridge-like elastic deformation member whose both ends are integrally fixed to a mounting member for mounting an electrical component having a mounting arm, and this elastic deformation member has
A locking portion of a side opening is provided in which the mounting arm of the electrical component, which is rotated along with the mounting member, slides into and fits while elastically deforming the elastically deformable member. With this, it is possible to obtain a really solid retaining effect and to install electrical parts extremely reliably.Moreover, it is easy to install without requiring much force, and it is easy to operate after installation. Electrical components that have various excellent practical effects, such as being able to firmly maintain their installed state even against external forces from the opposite direction, and achieving excellent electrical reliability. It is possible to provide a mounting device for.
