Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a keyboard in which key switches are arranged side by side, and in particular, to a keyboard that improves the efficiency of key operations and extends the lifespan by reducing stress on the operator. .

[Technical background of the invention]

An example of a conventional keyboard will be explained with reference to FIG.

In Figure 2, the key switch SW is fixed claw 1.
a is formed on the body portion 1b and has a contact portion therein; a support portion 2 mechanically connected to the contact portion of the main body portion 1; a key top 3 provided at the end of the support portion 2; , is composed of a non-flexible lead wire 4 drawn out from the contact part of the main body part 1.
This key switch SW is attached to a base 5 by its fixing claw 1a, and a wiring board 6 disposed at the bottom of this base 5 and a lead wire 4 are electrically connected by solder or the like. A key switch like this
A keyboard is constructed by arranging multiple SWs in parallel.

[Problems with background technology]

In the conventional keyboard configured as described above, there is no play (gap) between the key switch SW and the base 5, so that stress accumulates on the switch itself and the operator during operation. especially,
Even when the key top 3 is depressed from an oblique direction, this is forcibly changed to a direct depression operation, and the force of the depression is not absorbed. As a result, stress is concentrated on the operator and the switch itself, resulting in a decrease in key operation efficiency and a shortened lifespan of the keyboard.

[Purpose of the invention]

The present invention was made based on the above circumstances, and
The purpose is to provide a keyboard that improves the efficiency of key operations by reducing stress on the operator and extends the life of the keyboard.

[Summary of the Invention] In order to achieve the above object, the keyboard according to the present invention includes a main body portion having fixed claws formed in its body and a contact portion therein, and a strut mechanically connected to the contact portion in the main body portion. The fixing claw of the key switch, which is composed of a key top provided at the end of the support section, and a flexible lead wire drawn out from the contact section in the main body section, is locked to the base and cushion material. By doing so, the main body of the key switch is supported by the base and the cushion material, and the flexible lead wire is connected to the wiring board disposed at the bottom of the base. Features.

According to the keyboard according to the present invention having such a configuration, when the operator presses down the key top diagonally, the entire main body also moves diagonally, but since the main body is supported by the cushion material, , the diagonal force is absorbed by the cushion material. Therefore, stress is not exerted on the switch itself or the operator, improving the efficiency of key operations and extending the life of the keyboard.

In addition, even if the force pushing down the key top from an angle is excessive and cannot be absorbed by the cushion material, the lead wire is flexible, so the main body will not be restricted by the wiring board. You can move freely without stress, and you won't have to worry about stress.

In this way, in the present invention, in addition to supporting the key switch with the base and cushion material, a synergistic effect is achieved by providing flexibility to the lead wire, which reduces stress on the key switch from all directions. This reduction and stress reduction for the operator combine to improve key operation efficiency and extend the life of the switch.

[Embodiments of the invention]

An embodiment of the keyboard according to the present invention will be described below with reference to FIG. 1, in which the same parts as in FIG. 2 are given the same reference numerals.

In FIG. 2, an electrically insulating cushioning material 7 is provided at a portion of the main body 1 where the base 5 is attached by the fixing claw 1a, so that the main body 1 is supported by the base 5 and the cushioning material 7. The main body 1 and the wiring board 6 are connected by a flexible lead wire 8.

Next, the operation of this embodiment configured as described above will be explained. That is, when the operator presses down the key top 3 from an oblique direction, the entire main body 1 also tries to move in the diagonal direction, but since the main body 1 is supported by the cushion material 7, the force in the diagonal direction is It is absorbed by the cushion material 7. Therefore,
No stress is exerted on the switch itself or the operator, improving the efficiency of key operations and extending the life of the keyboard.

Further, even if the force pressing down on the key top 3 from an oblique direction is excessive and cannot be absorbed by the cushion material 7, the lead wire 8 has flexibility, so that the main body 1 is connected to the wiring board. You can move freely without being restricted by 6, and you won't feel stressed.

In this embodiment, the cushion material 7 is disposed on the upper part of the base 5, but depending on the point of force application between the main body 1 and the base 5, for example, the point of force application of the main body 1 is on the base 5. In the case of the key switch SW acting on the lower part of the base 5, the cushion material 7 may be provided at the lower part of the base 5 or the like. Further, even when the base 5 and the wiring board 6 are integrated or the same, the configuration in which the cushion material 7 is provided can be applied.

Furthermore, if electrical insulation between the main body portion 1 and the base 5 is not required, a cushion material 7 having no electrical insulation properties may be used.

The present invention is not limited to the above embodiments, but can be implemented with various modifications without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, according to the present invention, in addition to supporting the key switch with the base and cushion material, a synergistic effect is exerted by providing flexibility to the lead wire, which allows the key switch to be supported in all directions. It is possible to provide a highly practical keyboard in which the efficiency of key operations is improved and the life of the switch is extended by reducing the stress on the operator and the stress on the operator.
