BACKGROUND

1. Field of Invention

The present invention relates to a keycap. More particularly, the present invention relates to a keyboard with a keycap and a jig for painting the keycap.

2. Description of Related Art

The keycap of the keyboard could be moved vertically relative to the keyboard plate by the cooperation of the connected structures set on the keycap and set on the keyboard plate.

In some situation, the keycap is painted to provide a variety of looks. The keycap is mounted on the jig first, and then after the painting, baking, and printing process, the keycap is taken out from the jig and installed on the keyboard plate.

A conventional jig has a connected structure similar to the connected structure of the keyboard plate. Hence, the connected structure of the keycap can be connected with the connected structure of the jig to mount the keycap on the jig.

In order to reduce cost, the jig is reused repeatedly. However, after the painting and baking process, the size of the connected structure set on the jig could be changed. If the keycap is mounted on the jig which includes the changed size connected structure, the connected structure of the keycap is also out of shape. Hence, the painted keycap could not be installed on the keyboard plate stably. Furthermore, the painted keycap may disengage from the keyboard plate easily.

Therefore, how to solve the forging problem is an objective of the keyboard company.

SUMMARY

In accordance with the foregoing and other objectives of the present invention, a keycap for a plate of a keyboard is provided.

The keycap comprises a press surface, a hollow zone, a plate connection structure and a jig connection structure. The hollow zone is set on a side of the keycap opposite to the press surface. The plate connection structure is set in the hollow zone and used for connecting with the plate. The jig connection structure is used to connect with the keycap when the keycap is in a painting process. Moreover, the plate connection structure is not direct connected to the jig when the keycap is in the painting process.

In addition, the jig connection structure does not interrupt a moving path of the keycap.

A jig for painting the keycap is also provided herein. The keycap comprises a mounting structure. The mounting structure is set on the jig relative to the jig connection structure and used for connecting with the jig connection structure to mount the keycap on the jig. There is a distance between the mounting structure and the plate connection structure when the keycap is mounted on the jig.

A keyboard is also provided herein. The keyboard comprises a plate and a keycap. The plate has a keycap connection structure. The keycap is set on the plate and capable of moving vertically relative to the plate. The keycap comprises a hollow zone, a plate connection structure and a jig connection structure. The hollow zone has an opening toward to the plate. The plate connection structure is set in the hollow zone and connected to the keycap connection structure so that the keycap is set on the plate and used for moving vertically relative to the plate. The jig connection structure is separated from the keycap connection structure with a distance.

In the embodiment of the invention, the keycap further comprises a jig connection structure. When the keycap is in painting process, the keycap is mounted on the jig by the jig connection structure. Therefore, in the painting process, the plate connection structure which is set for connecting with the plate is not connected to the jig directly. Hence, the shape/size of plate connection structure is not changed after the painting process. When the painting process is finished, the keycap is installed on the plate by the plate connection structure. It can reduce the disengaging probability between the keycap and the plate.
