[0026] Embodiment 1

[0027] Please refer to Figure 1 and Figure 2The utility model provides a ceramic key cap with anti -deflection positioning structure one embodiment, including ceramic shell 1 and mounting seat 2, ceramic key cap hardness is high, wear -resistant oil light, long -term use does not oil, delicate and warm touch, knock sound long listen to, radiate fast, long -term use does not stuffy, surface compact smooth, easy clean does not leave fingerprint, and have natural antibacterial property, glaze texture is unique, luster elegant, adapt high -end custom keyboard, have practicality and artistic collection value simultaneously. The bottom of ceramic shell 1 is provided with connecting groove 101, mounting seat 2 includes base 201 and mounting column 202, and mounting column 202 is arranged at the bottom of base 201, and base 201 is inserted into connecting groove 101 and is bonded and fixed, and connecting groove 101 and base 201 are the same polygonal structure, in this embodiment, adopt square structure. The thickness of base 201 is about 1.1 millimeter, the shape is same with the connecting groove 101 of ceramic shell 1 but the size is slightly smaller and can be embedded into connecting groove 101, the connecting groove 101 of polygon is used to limit, can effectively prevent ceramic shell 1 from displacement and skew. Moreover, the area of base 201 is designed very large and occupies 80% area of the bottom of ceramic shell 1, and the large area of base 201 is more firm after bonding and can knock for a long time without debonding.

[0028] However, ceramic will produce shrinkage when sintering at high temperature, and the shrinkage rate is different due to the temperature difference in the kiln and the different batches of raw materials, so the size of each ceramic shell will have slight differences, and the tolerance is larger for larger size. To ensure that each mounting seat can be placed in the ceramic shell, the inner size of the shell is designed as large as possible during design, so that there will be a gap around when the mounting seat 2 is placed in the ceramic shell 1 for bonding, which is easy to cause slight deviation or rotation of the mounting seat in the ceramic shell. This key cap will be skewed when installed on the keyboard, and even collide with the adjacent key cap. In order to overcome the above problems, a plurality of positioning grooves 1011 are formed at the outer edge of the connecting groove 101, and a plurality of protrusions 2011 are correspondingly provided at the outer edge of the base 201, all the protrusions 2011 can be respectively inserted into the corresponding positioning grooves 1011, and the positioning grooves 1011 and the protrusions 2011 are used to limit twice, so as to ensure the matching accuracy even if there is a gap around when the mounting seat 2 is placed in the ceramic shell 1 for bonding.

[0029] In order to further improve the accuracy after matching, a plurality of positioning grooves 1011 extending straight from the center of the ceramic shell 1 to the outer side are formed at the outer edge of the connecting groove 101. By using the characteristic that the change of shrinkage rate during ceramic sintering only causes the size of ceramic to change, and the angle of the center angle does not change, the angle of the center angle between the positioning grooves 1011 remains consistent after ceramic sintering, thereby preventing the ceramic shell 1 from deviating and skewing when bonding with the mounting seat 2, and effectively improving the matching accuracy.

[0030] The top surface of the base 201 and the groove bottom of the connecting groove 101 are both planes, and the ceramic shell 1 keeps the same appearance and uniform wall thickness, which can effectively reduce the high-temperature shrinkage depression and other defects caused by uneven ceramic wall thickness during ceramic mold grouting, and the appearance is more flat and beautiful after sintering. In order to facilitate installation and alignment, the top surface of the base 201 is provided with a chamfer, so that the base 201 is more convenient to align when butting with the connecting groove 101.

[0031] The mounting column 202 is provided with a clamping groove 2021, which can be clamped with the shaft body of the keyboard. The side surface of the mounting column 202 is provided with a limiting rib 2022, which contacts the shaft body when the keycap is pressed to the bottom after being installed on the keyboard, thereby limiting the stroke. In order to increase the light transmittance, the mounting seat is generally made of transparent plastic material.

[0032] The outer surface of the ceramic shell 1 is provided with a glaze layer, which is beautiful and easy to clean. The thickness of the glaze layer is 0.1-0.3mm.

[0033] Embodiment 2:

[0034] Please refer to Figure 3 The difference between Embodiment 2 and Embodiment 1 is that this embodiment is improved for strip-shaped keycaps, mainly suitable for rectangular keycaps such as space bar. Since the longer ceramic keycap changes more in the length direction during sintering, the tolerance in the length direction is also larger, while the change in the width direction is smaller. Therefore, a plurality of positioning grooves 1011 are arranged at the outer edge of the connecting groove 101 in the width direction of the ceramic shell 1. The size in the width direction is small, so the influence is naturally smaller, and the precision is naturally higher.

[0035] Secondly, in order to adapt to the larger tolerance in the length direction, the positioning groove 1011 is provided with an assembly gap in the length direction of the ceramic shell 1. Even if the tolerance is larger, the protrusion 2011 can be inserted into the corresponding positioning groove 1011 by using the assembly gap. Moreover, since the change in the width direction is smaller, the precision after assembly will not be affected, and the ceramic keycap can still be ensured not to be skewed after assembly.

[0036] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
