Abstract

(57) [Abstract] [Purpose] By providing a structure in which the cover of the switch unit is integrated with the plate mounting frame, the steps during assembly can be omitted and workability can be improved. [Structure] A cover plate mounting frame, a fitting portion formed on both lower sides of the cover plate mounting frame, and a member engaging with a fitting hole of the fitting portion. An embedded push button switch having a switch unit having a stop projection and a push button hole through which a push button of the switch unit projects, in a unit cover.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embedded push-button switch in which a push-button operating portion is exposed and attached to the opening side of an embedded hole such as a wall surface.

[0002]

[Prior Art]

A conventional embedded push button switch has a fixing member 32 fixed in an embedding hole 31 of an embedding fixing member 30 as shown in FIG. 6, and a plate frame 50 and a mounting frame 51 are integrated. pre and the body - in DOO mounting frame 52 to fix the switch unit 4, a pre - and a structure for fixing a screw 33, 33 the door mounting frame 5 2 to the fixing portions 36. The switch unit 4 comprises a case 34 and a cover 35 to form a box.

[0003]

[Problems to be solved by the device]

Conventionally, the switch unit 4 is assembled by the cover 35 and the case 34, and the structure assembled to the switch unit 4 is fixed to the plate mounting frame 52. The cover 35 of the container unit 4 and the cover portion of the plate mounting frame 52 are overlapped with each other, and there is a problem in that assembly workability and the number of parts are wasted.

[0004]

[Means for Solving the Problems]

The present invention provides a structure in which the cover 35 of the switch unit 4 is integrated with the plate mounting frame 52 .

[0005]

[Function of the device]

By integrally forming the cover 35 of the switch unit 4 and the plate mounting frame 52 , the die manufacturing cost is reduced and the number of parts is reduced to improve the workability in the assembly, and the conventional combination is possible. The strength is improved compared to the existing products and the finish is more uniform than conventional products.

[0006]

【Example】

1 to 5, reference numeral 42 is a cover plate mounting frame body, which integrally forms the unit cover 40 and the plate mounting frame 41, and 1 and 1 are central portions of the unit cover 40. Push button holes formed in two places, push button holes 6 and 6 of the switch unit 4 project into the push button holes 1 and 1, and 2 and 2 are long holes for fixing to the fixing portions 36 and 36 with screws 33 and 33. is there. Reference numerals 3 and 3 denote mating portions having mating holes 3a and 3a, which are integrally formed on the cover plate mounting frame body 42 on both lower sides. The switch units 5 are fixed to the cover plate mounting frame 42 by engaging with the engaging holes 3a, 3a with fitting protrusions 3b and 3b. (1) Mating parts 3 and 3 have taper parts 3c and 3c on the inside, and (m) mating protrusions 3b and 3b have taper parts 3d and 3d. The unit 5 is easily fixed to the cover plate mounting frame 42 .

To fix the switch unit 5 to the cover plate mounting frame 42 , the taper parts 3d and 3d of the mating protrusions 3b and 3b and the mating parts 3a and 3a can be fixed. The switch unit 5 is pushed into the cover plate mounting frame 42 from the fitting portions 3a, 3a side by aligning the taper portions 3c, 3c with each other and the switch unit 5 is covered by the cover plate. It can be fixed to the mounting body 42 .

[0008]

[Effect of the device]

 The present invention has the following effects by integrally forming the cover of the switch unit with the plate mounting frame. (1) The cover of the switch unit and the cover plate mounting frame can be assembled in one step, and the conventional switch unit with the cover fixed to the plate mounting frame is fixed. In comparison, one process can be omitted and workability of assembly can be improved. (2) Compared to the case where the switch unit cover and the plate mounting frame are separate, the push button operation surface and the plate mounting frame surface are more uniform, the strength is improved and the die manufacturing cost is reduced. Wear.
