Abstract

The utility model provides a utility model provides a fork-shaped structure of keyboard key PAD points on a single layer. The fork-shaped structure includes PAD points on the upper layer and PAD points on the lower layer, wherein the PAD points on the upper layer are communicated with the PAD points, the PAD points adopt a communication circuit structure, and cross-connections of key points are not connected. The forks-shaped structure can simplify the production technology of a keyboard circuit board to reduce load influence factors, and has the advantages as follows: the key loading becomes stable, the keys of the keyboard still fell smooth after long-term use, the yield is improved for the production process of circuit boards, the production cost is saved and the production efficiency is improved.

Description

" fork " shape structure of keyboard PAD point on individual layer

Technical field

The utility model relates to the modular construction of notebook computer, particularly " fork " shape structure of keyboard PAD point on individual layer in the notebook computer.

Background technology

Keyboard PAD point be circular in the existing common notebook computer, and operation principle is that upper and lower PAD point is distinguished connection line, by knocking the upper and lower circuit of key point conducting, and the wiring board complex manufacturing, key point loading value is wayward, and its generation undesirable element is more.

Summary of the invention

The purpose of this utility model is to have deficiency at prior art, " fork " shape structure of a kind of keyboard PAD point on individual layer is provided, by reducing key point loading undesirable element (weight, sensitive excessively), simplify production technology, avoid keyboard loading bad (weight, sensitive excessively).

The technical solution adopted in the utility model is: " fork " shape structure of a kind of keyboard PAD point on individual layer, comprise upper strata PAD point and the PAD of lower floor point, described upper strata PAD point is a conducting PAD point, and the described PAD of lower floor point is the conducting line construction, and key point place intersects and do not connect.

The utility model be with keyboard conducting line design in lower floor, key point place intersects and not to connect, upper strata key point place is designed to conducting PAD point.When knocking key point, upper strata PAD point conducting lower floor " intersection " key point is to realize line conduction.Behind described " fork " shape PAD point assemblying keyboard, the upper and lower PAD point contact of keyboard is steady, and the button loading value more tends towards stability with respect to circular design.Do not have the conducting circuit because of the upper strata, printing area reduces, so the sticking floating dust that falls within on the wiring board can effectively be avoided in the wiring board production process, has reduced to a large extent to cause keyboard to cross the bad of sensitivity by foreign matter.

The utility model beneficial effect: 1, can reduce keyboard circuit board production technology, thereby reduce the loading influencing factor; 2, the button loading more tends towards stability, and the long-term practical button feel of keyboard is steady, has improved yield in the wiring board production process greatly; 3, save production cost to a great extent, improved production efficiency.

Fig. 1 is the structural representation that the utility model upper strata PAD is ordered;

Fig. 2 is the structural representation that the PAD of the utility model lower floor is ordered.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

As depicted in figs. 1 and 2: " fork " shape structure of a kind of keyboard PAD point on individual layer, comprise upper strata PAD point 1 and the PAD of lower floor point 2, described upper strata PAD point 1 is conducting PAD point, and the described PAD of lower floor point 2 is the conducting line construction, and key point place intersects and does not connect.

Claims

1. " fork " shape structure of a keyboard PAD point on individual layer, comprise upper strata PAD point (1) and the PAD of lower floor point (2), it is characterized in that: described upper strata PAD point (1) is a conducting PAD point, and the described PAD of lower floor point (2) is the conducting line construction, and key point place intersects and do not connect.
