Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which the products of the present invention are usually placed in when used, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "suspended" and the like do not imply that the components are absolutely required to be horizontal or suspended, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise specifically stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a communication between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b): as shown in fig. 1, a keyboard key signal fast triggering structure comprises a key body, wherein the key body is sequentially provided with a keycap 1, an upper PET2 layer, an upper circuit layer 3, an upper glue layer 4, a middle layer 5, a lower glue layer 6, a lower circuit layer 7 and a lower PET8 layer from top to bottom; an upper layer PAD and a lower layer PAD which correspond to each other up and down are respectively arranged on the upper line layer and the lower line layer 7, and a convex quick-contact communicating block is arranged on one surface of the upper layer PAD and the lower layer PAD; according to the keyboard key signal quick triggering structure designed by the scheme, the quick-touch communicating block is arranged on the surface of any one of the upper PAD and the lower PAD of the upper circuit layer 7 and the lower circuit layer 7, so that the strokes of the upper PAD and the lower PAD which are in contact conduction are effectively reduced, and the corresponding function of quick triggering of the keyboard keys is realized.

The preferred embodiment is as follows:

the surface of the quick contact communicating block is a smooth round curved surface; the surface of the quick contact communicating block is set to be the smooth circular curved surface, so that the height of the quick contact communicating block can be further improved in a limited space, the contact conduction stroke of the upper PAD and the lower PAD is shortened, and meanwhile, the smooth circular curved surface has more stability than a plane in contact conduction.

The quick contact communication block is specifically conductive silver paste printed on the surface of the PAD of the circuit layer; in the actual production process, the PAD point is also conductive silver paste which is conductively printed on the flexible circuit board, so that the quick contact connecting block is formed by printing a layer of conductive silver paste on the PAD again.

The diameter of the quick contact communicating block is smaller than that of the PAD of the line layer; because the inner space of the key is limited, the cross section area of the quick contact communicating block can be properly reduced on the premise of not influencing the function of the quick contact communicating block, and meanwhile, the printing is facilitated.

The thickness atmosphere of the quick contact communication block is as follows: the thickness of the quick touch communicating block is better between 0.005mm and 0.009mm as proved by a plurality of times of experimental data, so that the quick touch function of the key can be ensured, and the problem that the key is too sensitive and mistakenly touched due to the overlong quick touch communicating block can not influence the use experience.
