Abstract

The utility model discloses a portable DVD keyboard plate, and relates to the field of DVD players. The DVD keyboard plate comprises a board frame and a PCB. The PCB is disposed on the board frame. Edges of the board frame are provided with threaded holes. The PCB is provided with key groups, and the key groups are formed with a plurality of electrodes. Two ends of the electrode are connected with keys. The key groups comprise a first key group, a second key group, a third key group, and a fourth key group, used for fitting different types of key devices. The DVD keyboard plate is compatible to four key plates, and is simple in structure and convenient in transportation. Due to reduction of types of the DVD keyboard plates, management is more convenient, and buyers can purchase on a large scale when purchasing the DVD keyboard plates. Due to increase of the number, the buyers can negotiate price with suppliers, so that cost is reduced. A production department does not need to make many production tools when producing, so production is reduced further. When a certain type of mold is obsolete, other molds can continuously use the compatible key plate. Thus, use ratio of resources is greatly improved. In conclusion, the DVD keyboard plate achieves profit maximization.

Embodiment

Below in conjunction with accompanying drawing, describe preferred implementation of the present utility model in detail.

Fig. 2 has shown the embodiment of the utility model portable DVD keypad: portable DVD keypad, comprise sheet frame 1, pcb board 2, described pcb board 2 is printed on sheet frame 1, described sheet frame 1 edge is provided with screw hole 4, described pcb board 2 is provided with button group 6, described button group 6 consists of some electrodes 5, described electrode 5 two ends are all connected with button 4, described button group 5 comprises the first button group, the second button group, the 3rd button group, the 4th button group, for adaptive different types of button setting, the keypad compatibility of the present embodiment 4 sections of keypad functions, thereby management is got up more convenient, purchasing agent can purchase in enormous quantities in buying, thereby reduce costs, when certain a mould is superseded, other moulds can continue to use compatible keypad, the utilization factor of resource improves greatly like this.

It should be noted that referring to Fig. 3, described the first button group comprises 4 row

bipolar electrode groups

101 and 1 row five electrode groups 102, and every 2 row of described bipolar electrode group 101 are located at respectively the two ends of pcb board, and described five electrode groups 102 are located between every 2 row bipolar electrode groups 101.
