Abstract

The utility model discloses an optimized key cap structure, which comprises a key cap and a plurality of positioning bosses, wherein the positioning bosses are integrally formed at the inner end of the key cap, and the part, integrally overlapped with the side edge of the key cap, of the side surface of each positioning boss is hollowed. The part of the positioning boss and the side edge of the key cap are hollowed, so that the thickness of meat of the structure is reduced, the thickness difference between the part of the positioning boss and the side edge of the key cap is kept almost consistent with the thickness difference between the part of the positioning boss and the side edge of the key cap, the product cannot shrink during molding, the attractiveness of the molded product is guaranteed, and the reject ratio of the product is reduced.

Description

Optimized key cap structure

Technical Field

The utility model belongs to the technical field of keyboards, and particularly relates to an optimized key cap structure.

Background

The keycap is positioned at the uppermost part of the keys and is a touch operation receiving surface of the keyboard. The existing key cap is generally formed by injection molding of ABS plastic, in order to ensure the product quality of the key cap, the appearance of the plastic part of the key cap is required to be smooth and good, and the surface of the plastic part cannot be shrunk.

However, when the plastic part of the key cap is injection molded, a boss is arranged on the side edge of the key cap, a part area of the boss is intersected with the periphery of the key cap, so that the thickness (meat thickness) of the boss is increased, a shrinkage phenomenon is easy to occur on the surface in the molding process of the plastic part product, a small pit is formed on the surface, the attractiveness of the product is influenced, and poor molding of the product is caused.

Disclosure of Invention

The utility model aims at: in order to solve the above-mentioned problem, an optimized key cap structure is provided.

The technical scheme adopted by the utility model is as follows: the utility model provides an optimized key cap structure, includes key cap and a plurality of location boss, location boss integrated into one piece locates the inner of key cap, the side of location boss is hollowed out with the integrative lapped part of side of key cap.

In a preferred embodiment, the inner end of the key cap is further injection molded with a plurality of bosses which are not integrally overlapped with the side edge of the key cap, and after the part of the positioning boss integrally overlapped with the side edge of the key cap is hollowed, the meat thickness of one side of the positioning boss positioned on the side edge of the key cap is consistent with the meat thickness difference of the bosses.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the part integrally overlapped with the side edge of the key cap is hollowed out, the thickness of the remaining structural meat in the positioning boss area is not greatly different from that of other bosses, so that the product cannot shrink during molding, the attractiveness of the molded product is guaranteed, the reject ratio of the product is reduced, and the production efficiency is greatly improved.

The marks in the figure: 101-keycaps, 102-mounting grooves, 103-positioning bosses, 104-bosses.

Detailed Description

The utility model will be described in further detail below with reference to examples and with reference to the accompanying drawings.

Referring to fig. 1-3, an optimized key cap structure, comprising: the key cap 101, a plurality of location boss 103, its integrated into one piece is at the inner of key cap 101, and the excavation is handled to the integrative overlap joint's of location boss 103 side and key cap 101 side part, and after the excavation was handled, the thickness phase difference of the regional remaining structure meat thickness of location boss 103 and other boss 104 departments is little, and the product just can not appear the shrink phenomenon when the shaping this moment, has guaranteed the aesthetic property after the product shaping, has reduced the product defective rate.

It should be noted that, the glue reducing treatment is also performed at the part where the side surface of the positioning boss 103 and the side edge of the key cap 101 are integrally overlapped.

Referring to fig. 2, the inner end of the key cap 101 is further injection molded with a plurality of bosses 104 which are not integrally overlapped with the side edge of the key cap 101, and after the portion, integrally overlapped with the side edge of the key cap 101, of the positioning boss 103 is hollowed, the thickness difference between the side edge of the key cap 101 and the thickness of the boss 104 is kept consistent.

Wherein, for long key cap, the inner indent of location boss 103 and key cap 101 has the mounting groove 102 that satisfies the steel wire card and go into, and is more stable when pressing down after the combination.

The part of the positioning boss 103, which is integrally overlapped with the side edge of the key cap 101, is hollowed, so that the meat thickness of the structure is reduced, the meat thickness difference between the part overlapped with the side edge of the key cap 101 and the meat thickness of the common boss 104 is kept almost consistent, at the moment, the product cannot shrink during molding, the attractiveness of the molded product is guaranteed, the reject ratio of the product is reduced, the production efficiency of the product is improved, and the mass production is facilitated.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
