Description

[Detailed Description of the Invention] <Industrial Application Fields> This invention relates to a mechanical key switch having a swing type key top, which is applied to, for example, audio equipment, television, office equipment, computing equipment, and the like.

<Conventional technology> Conventionally, this type of mechanical key switch is shown in Fig. 8~
The one shown in FIG. 9 has been put into practical use.

This mechanical key switch includes a switch body 5 that opens and closes the conduction state between terminals 52 by raising and lowering a plunger 51, and a holder 6 for supporting light emitting diodes 61, 61 that are detachably attached to one side of the switch body 5. and a swing type key top 7 which is engaged with and supported by the end of the holder 6 and the upper end of the plunger 51.

<Problems to be Solved by the Invention> The mechanical key switch having the above structure only includes an engaging portion 62 and an engaging receiving portion 53 having a dovetail groove structure that are removable from each other in the holder 6 and the switch body 5. Because of this structure, the number of light emitting diodes 61 that can be installed is limited to the number of light emitting diode mounting parts formed in the holder 6 in advance. For this reason, there has recently been a strong demand in the industry for a mechanical key switch that attaches more light emitting diodes to a single switch body than the number of attachment parts the holder has, but currently such a switch is not available. not exist.

This invention was made in view of the above-mentioned problem, and aims to provide a mechanical key switch in which a large number of light emitting diodes can be mounted on the switch body.

<Means for Solving the Problems> The mechanical key switch of this invention consists of a switch body, one or more holders, an oscillating key top, and a light emitting diode.

The switch body has an engagement receiving portion on a side surface and a plunger on an upper surface that opens and closes a conductive state between the terminals by moving up and down.

The holder has a rectangular planar shape, and has two orthogonal sides having an engagement portion that can be engaged with and detached from the engagement receiving portion of the switch body, and two other orthogonal sides that have an engagement portion that can be engaged with and detached from the engagement receiving portion of the switch body. It has a removable engagement receiving part, and also has an attachment part on the top surface for attaching a light emitting diode.

The swing type key top is provided with a window hole portion at a position corresponding to the mounting portion of the holder, and a connecting leg connected to the plunger at a position corresponding to the plunger of the switch body.

The engagement between the engaging part and the engaging receiving part connects one or more holders to the switch body, attaches a light emitting diode to the mounting part of each holder, and attaches a light emitting diode to the switch body and each holder. A swing type key top is provided, and each light emitting diode is made to protrude from the window hole.

<Function> Since it is possible to attach a predetermined number of light emitting diodes to the attachment part of the holder, if fewer than the attachable number of light emitting diodes are provided, one holder is connected to the switch body. In addition, when installing more light emitting diodes than can be attached, two or more holders are connected to the switch body according to the number of light emitting diodes.

<Example> This invention will be specifically described below based on an example shown in the drawings.

The illustrated mechanical key switch has a plunger 11
A switch body 1 that opens and closes the conduction state between terminals 12 by lifting and lowering the switch body 1, a holder 2 for supporting a plurality of light emitting diodes 4 detachably attached to one side of the switch body 1, and an end of this holder 2. and a swing type key top 3 supported on the upper end of the plunger 11.

The holder 2 is a synthetic resin molded body having a square or rectangular planar shape, and has a plurality of mounting portions 21 on its upper surface to which the lower portions of the light emitting diodes 4 fit.
A pair of terminal mounting holes 22 are formed at the bottom of each mounting portion 21, and support pieces 23 projecting rearward are provided at the upper ends of the left and right side walls.

In this holder 2, two orthogonal side surfaces have a protrusion-shaped engagement portion 24 that can be engaged with and detached from a dovetail-shaped engagement receiving portion 13 formed on the side surface of the switch main body 1.
On the other two orthogonal sides, there is a dovetail-shaped engagement receiving part 25 that can be engaged with and detached from the engagement part 24 of another holder.
are formed, respectively, so that the switch main body 1 and the holder 2 and the plurality of holders 2 and 2a can be connected to each other.

The key top 3 is a keyboard-shaped plate whose width corresponds to the planar shape of the switch body 1 and the holder 2 when the switch body 1 and the holder 2 are connected. A higher fingertip operation section is integrally formed at the front end of the upper surface. When the key top 3 is in a state where the pivot hole is locked to the support piece of the holder 2, each light emitting diode 4 is attached to the key top 3 corresponding to the mounting portion 21 of the holder 2.
A window hole portion 34 for protruding the switch body 1 and a connecting leg 35 connected to the plunger 11 in correspondence with the plunger 11 of the switch body 1 are provided.

Each of the window holes 34 of the key top 3 may be formed into an open state, but may also be formed of a thin wall that can be pierced, and opened by piercing the thin wall as necessary. In addition, two or more holders 2, 2
When the key top 3 is connected, the key top 3 is formed to have a width corresponding to the planar shape of the switch body 1 and the plurality of holders 2, 2a connected thereto, and the pivot hole 31 engages with the support piece of the outer holder 2a. Stop. At this time, it goes without saying that the key top 3 is formed with a thin-walled window hole 34 that is open or can be opened, corresponding to the light emitting diode 4 of each holder 2, 2a, as in the previous example.

Therefore, the mechanical key switch of this invention connects the engagement receiving part 13 of the switch body 1 and the engagement part 24 of the holder 2, and the pivot hole 31 of the key top 3
The key top 3 is formed by locking the support piece 23 of the holder 2 on the holder 2 and connecting the connecting leg 35 to the plunger 11. The plunger 11 is moved up and down.

To connect a plurality of holders 2, 2a when supporting a large number of light emitting diodes 4, first connect one holder 2 to the switch body 1, and then connect the other holder 2a to the engagement receiving portion 25 of the holder 2. , and the mounting portions 21 of each holder 2, 2a.
A light emitting diode 4 is attached to each. Next, insert the pivot hole 31 of the key top 3 into the outer holder 2.
By pivoting to the support piece 23 of a and connecting the connecting leg 35 to the plunger 11, each light emitting diode 4 is located in the corresponding window hole 34, and a large number of light emitting diodes 4 are connected to a single switch body 1. Can be equipped with.

<Effects of the invention> As described above, this invention consists of a switch body having a light emitting diode and an engagement receiving part on the side, and a switch body having an engaging part and an engagement receiving part on the side and a light emitting diode on the top surface. A mechanical key switch is constituted by one or more holders each having a mounting portion and a swing type key top having a window hole, and the engagement between the engaging portion and the engaging receiving portion allows the switch body to be attached to the main body of the switch. One or more holders are connected to each other, a light emitting diode is attached to the mounting part of each holder, and a swing type key top is provided on the switch body and each holder so that each light emitting diode protrudes from the window hole part. Therefore, a large number of light emitting diodes can be easily provided on a single switch body via a plurality of holders, which is a remarkable effect of achieving the object of the invention.
