Examples

As shown in fig. 1 to 3, a plastic side key 2 includes a housing 1,

a key hole 11 is positioned at the side edge of the shell 1, and a side key 2 is arranged at the position of the key hole 11;

a PCBA board 3, which is positioned on the inner side of the shell 1,

a tact switch 4 fixed on the side of the PCBA board 3,

and the silica gel pad 5 is positioned between the side key 2 and the tact switch.

The tact switch 4 is arranged at the side edge of the PCBA board 3, so that the PCBA board 3 supports the tact switch 4 which is arranged laterally, the stability of the tact switch 4 which is arranged laterally is increased, meanwhile, the silica gel pad 5 is arranged between the tact switch 4 and the side key 2, and the side key 2 is flexibly matched with the tact switch 4, so that the problem of loud key sound in the use process of the side key 2 is solved.

At this time, if a plurality of keys are disposed in the housing 1, in order to improve the key production efficiency, all the key silica gel pads 5 in the housing 1 are in an integral structure. The silica gel pad 5 of all keys is arranged into an integrated structure, so that in the using process, the silica gel pad 5 of all keys can be installed only by installing the silica gel pad 5 once, and the production efficiency is improved.

In order to reduce the production cost, in this embodiment, the side key 2 is a plastic key, and the use of the plastic key not only can reduce the production cost, but also is not easy to damage compared with a silica gel key, thereby increasing the service life of the side key 2.

Since the side key 2 moves in the key hole 11, in this embodiment, in order to avoid the side key 2 from moving out of position in the key hole 11, the side key 2 is provided with a protrusion larger than the key hole 11, the protrusion being located at a position inside the key hole 11 of the housing 1. The side key 2 is installed from the inside of the case 1, and then the PCBA board 3 is installed to the inside of the case 1, so that the movement of the side key 2 can be restricted by the PCBA board 3, and thus the side key 2 can be moved only at the key hole 11 position.

Examples

As shown in fig. 1 to 3, a remote controller adopts a plastic side key 2 in the first embodiment.

At this time, the front face of the remote controller housing 1 is provided with a positive key 12, and the lower side of the positive key 12 is abutted to a switch on the upper side of the PCBA board 3 through the silica gel pad 5. The remote controller is provided with a plurality of positive buttons 12 in the front, and the side button 2 is provided with at least one, and the front and the side of remote controller all are provided with the button like this, to the positive button 12 of remote controller, also realize the control of switch on PCBA board 3 through the silica gel pad 5 of downside, the silica gel pad 5 of all buttons of remote controller (positive button 12 and side button 2) is an organic whole structure this moment, the quantity of silica gel pad 5 has been reduced, in the in-process of production, only need once install like this, just can install the silica gel pad 5 of all buttons, reduce the assembly step, simultaneously, also can avoid traditional structural design to feel the poor scheduling problem of uniformity of feeling because of assembly tolerance level is too much, promote the whole uniformity of feeling of button, simultaneously also can reduce material and equipment cost, promote the whole market competitiveness of product.

Further, because silica gel pad 5 is set up between side button 2 and tact switch 4 in the side direction position, consequently need to be higher to the position requirement of silica gel pad 5, silica gel pad 5 can not take place to shift after the installation, consequently in this embodiment, PCBA board 3 passes through the fastener to be fixed in casing 1 inboard, PCBA board 3 is equipped with a plurality of through-holes, silica gel pad 5 is equipped with the fixed column with the through-hole adaptation, silica gel pad 5 passes through the fixed column and is fixed with PCBA board 3, and at this moment, silica gel pad 5 passes through the fixed column and is fixed with PCBA board 3, and PCBA board 3 passes through the fastener and is fixed with casing 1 to fix silica gel pad 5 and casing 1, simultaneously, PCBA board 3 can be spacing to side button 2, and the tact switch 4 of fixing in PCBA board 3 side position is also all fixed, thereby accomplishes the location and the fixed of spare part in casing 1.

Because the silica gel pad 5 of the side key 2 and the silica gel pad 5 of the PCBA board 3 are integrated, in order to extend the silica gel pad 5 to the side edge position of the PCBA board 3, the silica gel pad 5 is arranged into a bending shape, and the silica gel pad 5 needs to be extended to the side edge of the PCBA board 3 through the position of the side key 4, in the embodiment, the silica gel pad 5 is provided with a containing groove 51 at the position of the side key 4 for containing the side key 4, and the outer side edge of the containing groove 51 is positioned between the side key 2 and the side key 4. After the tact switch 4 is fixed at the side position of the PCBA board 3, the tact switch 4 is higher than both sides of the PCBA board 3, so in order not to affect the installation of the tact switch 4, the silica gel pad 5 is provided with a receiving groove 51 for receiving the tact switch 4 without affecting the integral structure of the silica gel pad 5.

Because silica gel pad 5 need extend to the shape of bending in the side position, and in the in-process of using, silica gel pad 5 receives the extrusion and can remove, consequently in order to guarantee the intensity of silica gel pad 5, silica gel pad 5 side is equipped with the strengthening rib 52 that is higher than silica gel pad 5 top surface, accommodation groove 51 is located the downside position of strengthening rib 52. After the reinforcing ribs 52 are added, the strength of the silica gel pad 5 at the side edge position can be improved, so that the deformation of the silica gel pad 5 in the use process is avoided, the normal function of the silica gel pad 5 is affected, and the overall service life of the remote controller is prolonged.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
