Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a slide switch used for a power switch, a volume changeover switch, a function selection switch, etc. of an electronic device or the like.

[Prior Art] Conventionally, as shown in FIG. 3, a slide switch of this type has a head 3a of a knob 3 from the inside of a square hole 2 provided in a housing 1, as shown in FIG.
, And the head 4a of the switch body 4 is adhered to the recess 3d provided in the knob 3 with the double-sided tape 6.
Was held in the switch body 4.

[Problems to be Solved] In the above-described conventional slide switch, since the double-sided tape and the switch body are held, it is necessary to remove the release paper from the double-sided tape, which is inefficient.

In addition, the knob cannot be locked to the housing before mounting the switch body, and the knob may fall off during the installation of the knob in the housing, or the knob may come off and be lost during maintenance. There was a fear of.

The present invention has been made in consideration of the above-mentioned problems,
You can easily incorporate the knob into the housing of the electronic device,
Moreover, it is an object of the present invention to provide a slide switch in which the knob does not drop out of the housing after being assembled.

[Means for Solving the Problems] In order to achieve the above object, the present invention relates to a slide switch having a slidable knob mounted on a hole provided on one surface of a housing of an electronic device or the like, wherein the knob is Of the head exposed to the outside, a neck extending from the head and capable of being inserted into the hole, and an end continuous with the neck formed on one side in a direction orthogonal to the sliding direction, and inside the housing. The switch main body comprises a recess for locking the head of the switch body, and a step protruding from one side surface of the end portion opposite to the side surface where the recess is formed and hooked on the inner edge of the hole.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a slide switch according to an embodiment of the present invention, and FIGS. 2 (a) and 2 (b) are vertical cross-sectional views before and after the knob of the same embodiment is incorporated into a housing. FIG. 6C is a cross-sectional view of the same embodiment after being assembled.

In the drawings, 1 is a housing of an electronic device. A guide groove 1a is provided on one surface of the housing 1, and a square hole 2 is provided at the center of the guide groove 1a.

Further, 3 is a knob, and includes a head 3a, a neck 3b, an end 3c, and a recess 3
It is composed of d and step 3e.

The head 3a has a horizontally long shape that is longer than the square hole 2 and shorter than the guide groove 1a, and is exposed to the outside of the housing 1 while being guided by the guide groove 1a.

The neck portion 3b is formed so as to protrude from the head portion, and an end portion 3c located inside the housing is provided at the end portion thereof. Where the neck
The width of 3b is smaller than that of the square hole 2 so that it can slide to the left and right. The end 3c is slightly smaller than the square hole 2 so that the end 3c can penetrate from the outside of the housing.

Furthermore, a concave portion 3d that engages with the head portion 4a of the switch body 4 is formed on one side surface of the end portion 3c in a direction orthogonal to the sliding direction, and the side surface on which the concave portion of the end portion 3c is formed is formed. On one side surface on the opposite side, a step 3e is provided so as to be hooked on the inner edge of the square hole 2.

The switch body 4 is mounted on the printed circuit board 5, and switches the switch by moving the head 4a.

When mounting the slide switch having such a structure, the procedure is as follows.

First, the head portion 4a of the switch body 4 mounted on the printed circuit board 5 provided opposite to the housing 1 is positioned at the central portion of the square hole 2 of the housing 1.

Then, the end portion 3c of the knob 3 is pressed into the square hole 2. Edge 3c
When is pressed, the recess 3d engages with the head 4a of the switch body 4, and the step 3e provided below the end 3c is caught on the inner edge of the square hole 2 by the elasticity of the end 3c. As a result, the end portion 3c of the knob 3 is sandwiched between the head portion 4a of the switch body 4 and the side surface of the square hole 2 of the housing 1, so that it does not easily come out of the housing. become. On the other hand, it is possible to slide left and right. As a result, the switch body 4 can be operated by sliding the knob 1.

[Effects of the Invention] As described above, according to the present invention, since the knob can be attached to the housing by simply press-fitting the knob and the switch body and locking them, the work of assembling the knob becomes easy, and Even after the assembly, in the normal state, the knob does not drop out from the housing in the normal state, and the slide switch can be easily replaced.
