Abstract

The utility model relates to a combined keyboard used simultaneously for computers and telephones, comprising a plurality of keys. Each key comprises a fixed sheet 1 arranged on a printed circuit board, a movable sheet 2 made of conductive rubber and a key top 3. The fixed sheet 1 and the movable sheet 2 are respectively split into four sections corresponding to each other. The sections of the fixed sheet are composed of a sector section and a straight-edge section which is near and adjacent to a straight edge of the sector section. The sections of the fixed sheet which are positioned at the diagonal position respectively form two groups of key contacts. The combined keyboard is successfully applied to the device comprising a telephone and a computer. No matter whether the direction of the force used by fingers to press down each key is deviated, reliable contact of each group of keys can be ensured.

plate part

2,22,23,24) fan-shaped size is slightly larger than each zone (11 in the described stator part 1,12,13,14) size, each zone (21 in the described moving

plate part

2,22,23,24) each zone (11 in installation site and the described stator part 1,12,13,14) position is corresponding, 11A and 13A parallel connection in the described stator part 1 in one group of zone 11 and 13 that is in diagonal position, 11B and 13B parallel connection constitute first group of key contacts respectively, and another group is in 12A and the 14A parallel connection in the zone 12 and 14 of diagonal position in the described stator part 1,12B and 14B parallel connection constitute second group of key contacts respectively.

The composite keyboard that can be simultaneously uses for computer, phone that provides according to the utility model, it is characterized in that, four regional institute regions of described stator part 1 are the circle of 14 millimeters of diameters, and the distance of a sector region (11A, 12A, 13A, the 14A) right-angle side in each zone and adjacent linearity region (11B, 12B, 13B, 14B) is 0.5 millimeter in the described stator part 1.

The composite keyboard that can use for computer, phone simultaneously of the present utility model successfully is applied to comprise in the logical machine of the strange information in sky of telephone set part and computer part, no matter firmly whether deflection is arranged during each button of button finger contact, can both guarantee two groups reliable by key contacts.This keyboard also can be used in the equipment of two groups of keyboards of other needs.

In conjunction with the accompanying drawings, further specify embodiment of the present utility model.

Fig. 1 is the structural representation of each button stator part in the composite keyboard that can be simultaneously uses for computer, phone of the present utility model;

Fig. 2 is the structural representation of the moving plate part of each button in the composite keyboard that can be simultaneously uses for computer, phone of the present utility model;

Fig. 3 is the sectional structure schematic diagram of each button in the composite keyboard that can be simultaneously uses for computer, phone of the present utility model.

Composite keyboard of the present utility model is made up of a plurality of keyboards, and each button wherein can produce two groups of different signals simultaneously when being pressed, and the phone part that is respectively the computer part in the equipment is used.Button in this keyboard is mainly made moving plate, printed circuit board (PCB) by conductive rubber and is made stator and realize.

As shown in Figure 1, the stator part 1 of each button is to be printed in the circle of 14 millimeters of diameters on the printed circuit board (PCB) in the composite keyboard that can be simultaneously uses for computer, phone of the present utility model, and this circle is divided into four sector regions (each central angle be 90 spend) 11,12,13,14.Each sector is divided into two again, and one is fan-shaped (11A, 12A, 13A, 14A), and another piece is two limits (11B, 12B, 13B, 14B) that are linked to be the right angle, and the spacing between them is 0.5 millimeter.11A constitutes two contacts of one group of key switch respectively with 13A is connected in parallel, 11B and 13B are connected in parallel in two sectors (11,13) on the diagonal, and two sectors (12,13) on another diagonal of face constitute two contacts that another organizes key switch with the same manner.
