Abstract
The invention discloses an annular keyboard contactor which is located on a keyboard polyester film switch and communicated with a printing circuit. The annular keyboard contactor comprises an outer ring and a central point. A gap is formed between the outer ring and the central point. The outer ring is in a circular ring shape. The central point and the outer ring are concentric. A wire is communicated between the outer ring and the central point. The annular keyboard contactor reduces the key-point contact area, and effectively avoids foreign matter of a PAD point, the probability of key lightness generation can be remarkably reduced, and the production cost is saved.
Description
Technical field
The present invention relates to a kind of structure using the input unit of manual operation switch, be specifically related to a kind of annular keyboard contact, be applied in keyboard of notebook computer.
Background technology
The polyester film switch of existing keyboard of notebook computer adopts the structure of circular PAD point 1 as shown in Figure 1, and is connected with the printed wire 2 of keyboard.In air, floating dust is entrained between keyboard Key point in process of production, easily causes the light nothing of button.How to reduce Key point cantact area, effectively avoid PAD point foreign matter, light without producing probability to reduce button; Simultaneously cost-savingly become technical problem urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the simple annular keyboard contact of a kind of technique.
Technical scheme: for solving the problems of the technologies described above, annular keyboard contact provided by the invention, be positioned on keyboard polyester film switch, and be connected with printed wire, it is characterized in that: described annular keyboard contact comprises outer ring and central point, has gap between outer ring and central point, and described outer ring is annular, described central point is the concentric circles with outer ring, is communicated with wire between described outer ring and central point.
Particularly, described annular keyboard contact is printed in the lower surface of upper strata polyester film.
Particularly, described annular keyboard contact is printed in the upper surface of lower floor's polyester film.
Particularly, the area of described central point accounts for 30% ~ 50% of whole annulus cylindrical area.
Particularly, described wire is positioned in annulus radial direction, comprises the first wire and second wire of 60 ° of angles each other.
During use, the upper and lower PAD point of polyester film switch key is designed to annular, and ring-shaped P AD point and connection, with operation printing.After ring-shaped P AD point assemblying keyboard, keyboard upper and lower PAD point cantact area ratio circular PAD point reduction 1/2, and button loading value more tends towards stability relative to circular design.Because PAD point cantact area reduces, therefore in polyester film switch production process, the floating dust of stick-down on PAD point can effectively be avoided, and reduces to a large extent and causes keyboard gently without bad by foreign matter.
Beneficial effect:
1. can reduce and cause keyboard gently without bad by foreign matter, button loading more tends towards stability, and keyboard Long-Time Service handfeel of keys is steady.
2. annular PAD point design described in saves production cost to a great extent.
3. annular PAD point design described in does not increase production process, does not affect original production efficiency.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the present invention recited above solves, the advantage that the other technologies feature comprised in the other technologies problem that annular keyboard contact of the present invention can solve, technical scheme and these technical characteristics bring, will be described in more detail by reference to the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing keyboard contact;
Fig. 2 is the structural representation of the annular keyboard contact of the embodiment of the present invention one;
Fig. 3 is the structural representation of the annular keyboard contact of the embodiment of the present invention two;
In figure: 1PAD point, 2 printed wires, 11 outer rings, 12 central points, 13 wires, 13-1 first wire, 13-2 second wire.
Embodiment
Embodiment one:
The present embodiment as shown in Figure 1, be positioned on keyboard polyester film switch, and be connected with printed wire 2, this annular keyboard contact comprises the outer ring 11 and central point 12 that form gap each other, wherein outer ring 11 is in annular, central point 12, as the concentric circles of outer ring 11, is communicated with wire 13 between outer ring 11 and central point 12.
Embodiment two:
The present embodiment is the improvement on embodiment one basis, and as shown in Figure 2, its main improvements are: wire comprises the first wire 13-1 and the second wire 13-2, is all positioned at annulus 11 with in the radial direction of central point 12,60 ° of angles each other.Outer ring 11 is connected with printed wire 2, and this printed wire 2 staggers mutually with the first wire 13-1 and the second wire 13-2.
Below by reference to the accompanying drawings embodiments of the present invention are described in detail, but the present invention is not limited to described execution mode.For those of ordinary skill in the art, in the scope of principle of the present invention and technological thought, multiple change, amendment, replacement and distortion are carried out to these execution modes and still falls within the scope of protection of the present invention.
Claims (5)
