Description

[Detailed Description of the Invention] The present invention relates to a bush switch mounting device that makes it possible to eliminate assembly errors.

When installing a button switch in a television receiver, etc., the button switch with an integrated push button is fixed to the chassis, the push button is fitted into the through hole in the front panel, and the panel is fixed to the chassis. Not only is the work somewhat difficult, but due to the assembly accuracy and yield of assembled parts,
Misalignment between the through hole and the push button is likely to occur, and the through hole must be made large in diameter, resulting in an unsightly appearance.

Therefore, in view of this point, conventionally, as shown in Fig. 1,
The configuration is such that a push button assembly 3 consisting of a front panel 1 and a push button 3a urged inward by a compression spring 2 is brought into contact with a switch lever 5a of a bushing switch 5 fixed to a chassis 4.

However, conventional equipment that refuses to do so results in complicated assembly work and increased costs.

The present invention was devised in view of the above points, and it is possible to temporarily fix a bush switch with an integrated push button elastically without the need for fasteners such as screws when attaching it to a switch support. The object of the present invention is to propose a bushing switch mounting device that can easily align the insertion hole and the pushbutton when inserting the panel.

The present invention will be described below along with an illustrative embodiment.

FIG. 2 is an exploded perspective view of the main parts of this embodiment, and numeral 6 is a switch support made of synthetic resin, including a base 60 that locks and holds two bushing switches 5, and a tape. It is a molded body formed by integrally molding a counter holding part 61 that locks and holds the counter 8, and first and second fixing plates 62 and 63 on both sides.

The box-shaped base 60 has a U-shaped notch 60b on the front plate 60a for arranging the switch lever 5aw5a,
60b, and the back plate 60c is connected to the switch levers 5a, 5.
a pair of switch-holding ribs 60f, 60f for holding the surfaces of the bushing switches 5 on the bottom plate 60e;
60f, 60f and a pair of switch locking ribs 60g, 60gt 60g, 60g are formed which sandwich the side surfaces of the bushing switch 5.5 and elastically prevent removal from both sides of the upper surface.

Furthermore, this switch locking rib 60g + 60g...
・Hooks 60h, 60h, . . . are formed at the upper end.

Further, the counter holding portion 61 has counter holding ribs 61b, 61b, . . . and a pair of counter locking ribs 61c, 61c formed on the back plate 61a.

When assembling the device of this embodiment, first the bottom plate 60e of the base is assembled.
Elastic plates 7, 7 made of an elastic member such as synthetic rubber are arranged at positions sandwiched between the ribs, and two pairs of fixing metal fittings 5b, 5b, 5
b, 5b are the front plate 60a and the switch locking rib 60gt
60gt 60g, said push switch sandwiched between 60g.

5 is locked onto the elastic plates 7, 7.

The locked bushing switch 5.5 is firmly locked to the hooks 60h, 60h, etc. of the switch locking rib while being urged upward by the elastic plate 7. .

Next, the tape counter 8 is locked in the same manner as the bush switch without using the elastic plate, and the chassis 4 is brought into contact with the back surface of the first fixing plate 62 and the front surface of the second fixing plate 63 of the switch support 6. At least after screwing and fixing, the fixedly supported bush switches 5, 5 are electrically connected and the tape counter 8 is mechanically connected.

To attach the front panel 1 after completing the assembly work, insert the funnel-shaped cylindrical bodies 1b, lb formed on the back of the push button insertion holes 1a, la of the front panel 1, and insert the push button 3° with a tapered front part. 3 and fit together, and screwed and fixed to the pair of threaded portions 64, 64 of the switch support 6.

That is, the funnel portions of the cylindrical bodies 1b, 1b and the tapered portions of the front push buttons 3, 3 facilitate the fitting operation of the front panel, and the elastic plates 7, 7, the necks of the push buttons 3, 3. In order to allow swinging, even if the push buttons 3, 3 are eccentric with respect to the push button insertion holes 1a, la due to installation errors of the push buttons 3, 3, the elasticity of the elastic plates 7, 7 allows the push buttons 3, Since the condition No. 3 is corrected, there is no need to increase the diameter of the push button insertion holes 1a and la.

As described above, according to the present invention, when a bushing switch is attached to a switch support, the side portions of the bushing switch are held between the holding ribs, and the collar portion is held between the front plate and the locking rib. Furthermore, the bushing switch is elastically held by the elastic plate and the hook portion of the locking rib, so that the bushing switch can be positioned in the direction of the push button axis, in the direction perpendicular to this, and elastically in the vertical direction. Since the bushing switch is held in place, the bushing switch can be easily and reliably attached to the switch support without the need for fasteners such as screws.

Further, when the bushing switch is inserted into the cylindrical body, the elastic plate is elastically deformed so that the axis of the bushing switch and the center of the push button insertion hole coincide with each other. It can also absorb assembly errors.
