Description

A kind of ultra-thin key switch with illumination effect

Technical field

It the utility model is related to key switch, more particularly to a kind of ultra-thin key switch with illumination effect.

Background technology

Luminous button switch refers in setting ray structure in key switch to illuminate key switch.Existing luminous button is opened Close, be typically that the light-emitting component (such as light emitting diode) for being directly protruding into switch internal is set on the plate of direct-on-line road, to reach Illumination effect.This mode that light-emitting component is arranged to inside, according to the light-emitting component of large volume, then occupied space is big, According to the light-emitting component of small size, then light is difficult to large area diffusion；And light-emitting component needs electric energy ability self-luminous, increases Add power consumption.

Meanwhile then needed after general key switch production, it is necessary to switch it at the leg that pin is connected on wiring board Key switch and wiring board are attached.Existing key switch is directly fixed on wiring board, when some button Switch is when something goes wrong, it is necessary to be disassembled, and during dismounting, the parts in key switch have with wiring board It may be damaged, reduce life of product；And technique for fixing is complicated, work efficiency is low.

Utility model content

For above-mentioned deficiency, the purpose of this utility model is to provide a kind of ultra-thin key with illumination effect to switch, Light guide plate not only vacant key switch inner space, and light diffusion area is big, illumination effect is good.

The utility model is that technical solution is used by reaching above-mentioned purpose：

A kind of ultra-thin key switch with illumination effect, including key switch body, it is characterised in that further include setting A light guide plate in key switch body lower end, offers on the light guide plate and some is opened for what key switch body lower end was caught in Mouthful, and an inner wall of the opening protrudes to form an insertion leaded light block inwardly, in insertion leaded light block insertion key switch body.

As further improvement of the utility model, key switch body a side bottom is offered for embedded guide-lighting One socket of block insertion.

As further improvement of the utility model, the opening of the light guide plate is in concave shape.

As further improvement of the utility model, further include the soft-core wire road plate for being arranged at light guide plate lower end and set A base iron plate of soft-core wire road plate lower end is placed in, wherein, offered on the soft-core wire road plate and below edge of opening Some perforation, set up some buckles for sequentially passing through perforation and opening, in key switch body on the base iron plate Some card slots for being caught in are offered on lateral wall.

As further improvement of the utility model, the buckle with card slot is T-shaped or L-shaped.

As further improvement of the utility model, the width of the perforation is bigger than the thickness of buckle.

As further improvement of the utility model, the quantity of card slot is at least 2 on the key switch outer body wall It is a.

The beneficial effects of the utility model are：

(1) by being embedded in the embedded guide-lighting block structure of light guide plate in the bottom of key switch, light guide plate is by extraneous nature Light is directly absorbed and is conducted into by embedded guide-lighting block in key switch, does not increase power consumption not only, and on light guide plate Shine inside everywhere and key switch, realize key switch lighting function, illumination effect is good；Meanwhile embedded key switch The embedded guide-lighting block of bottom is block structure, and not only vacant key switch inner space, and light diffusion area is big, is improved Illumination effect；

(2) the engaging mounting means to be formed is combined with card slot using buckle, realizes and key switch body is fixed In on base iron plate, key switch body will not voluntarily come off from base iron plate after engaging, and the stability that is fixed is high, and As long as buckle is pulled outward, you can buckle is departed from card slot, realize and disassemble key switch body from base iron plate, produce The intact nothing of product parts is damaged, and can arbitrarily replace key switch, and assembly and disassembly are convenient and efficient.

Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and embodiment, to the utility model It is described further.

Brief description of the drawings

Fig. 2 is a part of structure diagram of the utility model；

Fig. 3 is another part structure diagram of the utility model.

Embodiment

Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose taken, below in conjunction with Attached drawing and preferred embodiment, describe specific embodiment of the present utility model in detail.

Fig. 1 to Fig. 3 is refer to, the utility model embodiment provides a kind of ultra-thin key switch with illumination effect, bag Key switch body 1 is included, the light guide plate 2 for being arranged at 1 lower end of key switch body is further included, confession is offered on the light guide plate 2 Some openings 21 that 1 lower end of key switch body is caught in, and an inner wall of the opening 21 protrudes to form insertion leaded light inwardly Block 22, the opening 21 for making the light guide plate 2 are in concave shape, in the insertion leaded light block 22 insertion key switch body 1.

In the present embodiment, 1 a side bottom of key switch body offers one be inserted into for embedded guide-lighting block 22 Socket 11, after embedded leaded light block 22 is inserted into socket 11, will be led to having by light guide plate 2 from the light that periphery is sent along light guide plate 22 The everywhere of light guide plate 22, as shown by the arrows in Figure 1 so that everywhere all shines, and by embedded guide-lighting block 22 pour into by Inside key switch body 1, make 1 internal illumination of key switch body.

In order to which key switch body 1 is preferably combined together with wiring board, the present embodiment key switch, which further includes, to be set The soft-core wire road plate 3 for being placed in 2 lower end of light guide plate and the base iron plate 4 for being arranged at 3 lower end of soft-core wire road plate, wherein, at this Some perforation 31 are offered on soft-core wire road plate 3 and below 21 edge of opening, set up on the base iron plate 4 according to Secondary some buckles 41 through perforate 31 and opening 21, offer what is be caught in for buckle 41 on 1 lateral wall of key switch body Some card slots 12.

Meanwhile the buckle 41 with card slot 12 is T-shaped or L-shaped, the buckle 41 is matched with card slot 12.

The width of the perforation 31 is bigger than the thickness of buckle 41, pulls buckle 41 beneficial to toward outside, makes buckle 41 from card slot Spin off in 12.

In the present embodiment, be buckled 41 quantity setting it is corresponding with the quantity of card slot 12, and the quantity of card slot 12 according to Specifically need and set, the quantity of 1 side card slot 12 of the present embodiment key switch body is at least two, it is preferred that it is 4, and 1 surrounding of key switch body is distributed in, beneficial to the fixation of key switch body 1.

By the setting of said structure, the buckle 41 on base iron plate 4 is passed through into the perforation 31 on soft-core wire road plate 3, so Key switch body 1 is put on soft-core wire road plate 3 afterwards, and buckle 41 is caught in the card slot 12 of key switch body 1, so that Key switch body 1 is fixed by realization to be installed on base iron plate 4.Meanwhile as long as pulling buckle 41 toward outside, you can will Buckle 41 spins off from card slot 12, realizes and separates key switch body 1 from base iron plate 4.

The emphasis of the utility model essentially consists in：

The above descriptions are merely preferred embodiments of the present invention, and not the technical scope of the utility model is made Any restrictions, therefore identical with the utility model above-described embodiment or approximate technical characteristic is used, and obtained other structures, Within the scope of protection of the utility model.
