Abstract

The utility model relates to a keyboard. An output and input circuit board is mainly connected to a bottom plate through a detachable connecting piece; the receiving end of the output and input circuit board is connected with a corresponding receiving end on a film circuit board; in addition, the panel position of the output and input circuit board is correspondingly provided with a cover plate which can be movably opened; therefore, the utility model has the advantages that a keyboard body is suitable for mass production, production cost is reduced, various keyboards can be assembled as required, and applicability is enlarged.

Description

Built-in interchangeable keyboard

The utility model relates to a kind of keyboard.

At present, known keyboard, micro controller (CPU) at the keyboard circuit unit generally sees through universal serial bus (Universal Serial Bus, be called for short USB) or the PS/2 transmission line be connected computer (PC), remove this, this keyboard also can see through infrared ray (IR) or radio frequency (RF) transmission mode, and this micro controller receives the order from computer, or from the data on the keyboard.Because micro controller is arranged in the keyboard body, if the client wants a large amount of multi-form keyboards (PS/2) keyboard, IR keyboard, RF keyboard), then on production line, because of its maneuverability is low, so production extremely is difficult for and can causes inventory problem.

In view of this, the purpose of this utility model provides a kind of built-in interchangeable keyboard, can be to change different circuit boards, and also keyboard specification more make identical keyboard body be suitable for a large amount of manufacturings, and a kind of this physical efficiency of keyboard is because of the different keyboard of market demand assembling.

The purpose of this utility model is achieved in that a kind of built-in interchangeable keyboard, it mainly has base plate, film circuit board, output/input circuit plate and panel, it is characterized in that: the output/input circuit plate is connected on the base plate with detachable connecting piece, and corresponding receiving end joins on the receiving end of this output/input circuit plate and the film circuit board, in addition, the panel place with respect to the output/input circuit plate is provided with the movable capping of opening.Has PS/2 specification interface or USB specification interface on the described output/input circuit plate.

Because adopt such scheme: the keyboard body is suitable for a large amount of productions, reduces production costs, and can assemble different keyboards on demand, application enlarges.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model first embodiment stereographic map;

Fig. 2 the utility model first embodiment exploded view;

Fig. 3 the utility model first embodiment assembled sectional view;

Fig. 4 the utility model second embodiment stereographic map.

Shown in Fig. 1-4, first embodiment, for the specification that makes keyboard 1 reaches the exchange function, being respectively equipped with suitable DIN specification on the output/input circuit plate 10 of keyboard 1 (represents (with PS/2 specification (with line 3 expressions) with line 2, or the wired or wireless or signal delivery circuit of USB specification (with line 4 expressions), and this circuit board 10 can be connected in the keyboard in the interlocking mode, corresponding golden finger 17 on the part that is provided with golden finger 11 with circuit board 10 and each film circuit board 12, again after the perforation of the perforation of the perforation 18 of passing circuit board with each screw 13 and film circuit board 12 and middle plate (not shown) at circuit board 10 both sides places, interlocking is on the pair of holes post 16 on keyboard 1 base plate 15, can with the terminal specification of keyboard signal line end, substitute above-mentioned circuit board 10 simultaneously, reach specification and substitute function, to save the material of how standby a keyboard 1 body of known fixing architecture, with the puzzlement that increases the stock, form a movable capping of opening 191 at keyboard case with respect to the panel 19 that is provided with circuit board 10 places, to be easy to open replacing; As shown in Figure 2, on this capping 191, can be provided with a cramp (not shown), in order to fix capping 191, as long as when need substitute the specification circuit board, capping replacing circuit board and the corresponding signal line of opening this keyboard get final product, wherein, the signal line of wireless type, as shown in Figure 4, and capping 191 can have multiple fixed form with circuit board 10, and the utility model does not limit; In addition, above-mentioned circuit board 10 only is not limited to the mode with the golden finger butt joint, also can be the interface arrangment of utilization connector; Promptly being with corresponding signal receiving end on the signal receiving end bonding film circuit board on the circuit board, is scope that the utility model comprises, and combining between circuit board and housing also is not limited to above-mentioned interlocking mode.

In sum, because the main body of keyboard all is the same, storage space and cost are increased, but the utility model is differentiation with the circuit board, can earlier the circuit board of all size be made respectively, single specification pattern (refers to mutually in specification, certainly keyboard can have the various appearances pattern, still, the difference of outward appearance is not discussed in addition) the keyboard body also make respectively, determine or will buy a kind of pattern of specification when client's order specification, when last package program, after the circuit board that is suitable for loaded onto, just applicable, in addition, the consumer is if bought old specification, when desire substitutes specification, as long as substitute circuit board, and the replacement mode is very simple, to save the cost of a large amount of this replacements of keyboard, reach the modularity functions of use, another function is suitable for multiple pattern, improves the applicability of keyboard greatly.

Claims

1, a kind of built-in interchangeable keyboard, it mainly has base plate, film circuit board, output/input circuit plate and panel, it is characterized in that: the output/input circuit plate is connected on the base plate with detachable connecting piece, and corresponding receiving end joins on the receiving end of this output/input circuit plate and the film circuit board, in addition, the panel place with respect to the output/input circuit plate is provided with the movable capping of opening.

2, by the described built-in interchangeable keyboard of claim 1, it is characterized in that: have PS/2 specification interface or USB specification interface on the described output/input circuit plate.
