Solve current keyboard and do not support the hot plug to change technological not enough that the button exists, including PCB board and photoelectric type button, the PCB board on be equipped with the joint hole that supplies photoelectric type button embedding joint, the embedding of photoelectric type button in the joint hole, be equipped with on the lateral wall of photoelectric type button with the fixed elasticity fastener of PCB board cooperation joint, the PCB board on be equipped with keyboard circuit, keyboard circuit includes the opto -coupler subassembly that corresponds with the photoelectric type button. The photoelectric type button is blocked the light signal of opto -coupler subassembly and is reached signal trigger, and it is fixed that the lateral wall of photoelectric type button and PCB inter -plate pass through elasticity fastener cooperation joint, presses down the elasticity fastener and just can conveniently take out the photoelectric type button and change alone, need not the computer operation of shutting down, support hot plug, convenient to use.
Description
Technical field
The utility model relates to computation and inputs all keyboard technique fields.
Background technology
Existing keyboard mainly has membrane keyboard and mechanical switch keyboard；Although membrane keyboard cost is low, but feel is poor, and the life-span is short, the poorest, and button can not be individually replaced；It is individually replaced although mechanical switch keyboard can realize button, but the key switch pin of mechanical switch keyboard with between the plug socket welded on pcb board by electrical grafting, namely key switch do not supports hot plug, carry out button replacement operation after needing shutdown, use inconvenience.
Summary of the invention
In sum, the purpose of this utility model is that solving existing keyboard does not support that the technical deficiency that button exists is changed in hot plug, and proposes a kind of hot swap type optical keyboard.
By solving the technical problem that the utility model is proposed, the technical scheme used is: hot swap type optical keyboard, include pcb board and photoelectric push-button, it is characterized in that: described pcb board is provided with the blocked hole for photoelectric push-button link, photoelectric push-button is embedded in blocked hole, and the sidewall of photoelectric push-button is provided with and coordinates the flexible clamp piece connected and fixed with pcb board；Described pcb board is provided with keyboard circuit, and keyboard circuit includes the optocoupler assembly corresponding with photoelectric push-button.
Described flexible clamp piece includes the barb being stuck in pcb board bottom surface, and barb connects has shell fragment connecting portion, shell fragment connecting portion to be connected with the sidewall of photoelectric push-button after extending to pcb board end face, and shell fragment connecting portion includes pressing position in pcb board top face position.
Also including upper cover and lower cover, pcb board is placed in the inner chamber of upper cover and lower cover composition, and photoelectric push-button is fixed on pcb board through upper cover.
Described blocked hole is provided with the fool proof lug boss coordinated with photoelectric push-button sidewall.
Described pcb board outer layer is provided with the waterproof sealing coating covered by keyboard circuit waterproof sealing, and the optical surface of optocoupler assembly is placed in outside waterproof sealing coating.
The beneficial effects of the utility model are: there is not the signal of telecommunication between photoelectric push-button of the present utility model and PCB and be connected, photoelectric push-button carries out blocking-up and reaches signal triggering the optical signal of optocoupler assembly, the sidewall of photoelectric push-button is connected and fixed with being coordinated by flexible clamp piece between pcb board, pressing flexible clamp piece just can be easily removed photoelectric push-button and be individually replaced, without computer power-off operation, support hot plug, easy to use.

Detailed description of the invention
Below in conjunction with the preferred specific embodiment of accompanying drawing and the utility model, structure of the present utility model is further described.
Shown in Fig. 6, the utility model includes pcb board 3 and photoelectric push-button 4, described pcb board 3 is provided with the blocked hole 31 for photoelectric push-button 4 link, photoelectric push-button 4 is embedded in blocked hole 4, and the sidewall of photoelectric push-button 4 is provided with and coordinates the flexible clamp piece 40 connected and fixed with pcb board 3；Described pcb board 3 is provided with keyboard circuit, and keyboard circuit includes the optocoupler assembly 5 corresponding with photoelectric push-button 4；Each photoelectric push-button 4 is to there being one group of optocoupler assembly 5, and each group of optocoupler assembly 5 includes photocell 51 and the light receiving element 52 being respectively placed in photoelectric push-button both sides.
In specific implementation process, as required, the utility model can also include upper cover 1 and lower cover 2, and pcb board 3 is placed in the inner chamber of upper cover 1 and lower cover 2 composition, and photoelectric push-button 4 is fixed on pcb board 3 through upper cover 1.
In order to realize pcb board 3 be in "on" position time, quickly and easily photoelectric push-button 4 is inserted and be fixed on pcb board 3, and quickly and easily it can be unloaded replacing from pcb board 3, reach the effect of hot plug, flexible clamp piece 40 adoptable one of which concrete structure includes the barb 401 being stuck in pcb board 3 bottom surface, barb 401 connects shell fragment connecting portion 402, shell fragment connecting portion 402 is connected with the sidewall of photoelectric push-button 4 after extending to pcb board 3 end face, and shell fragment connecting portion 402 is positioned at pcb board 3 top face position and includes pressing position 4021；During assembling, direct photoelectric push-button 4；During dismounting, just photoelectric push-button 4 can be extracted after pressing position 4021 is applied suitable pressure.
With reference to shown in Fig. 4 and Fig. 6, the blocked hole 31 of the utility model pcb board 3 is provided with one group of fool proof lug boss 32 coordinated with photoelectric push-button 4 sidewall；Fool proof lug boss 32 not only acts as and prevents photoelectric push-button 4 direction of insertion mistake, causes the optical signal of optocoupler assembly 5 to be in the state of being blocked all the time；The photocell 51 of optocoupler assembly 5 and light receiving element 52 can also be respectively arranged on fool proof lug boss 32 basal surface position of blocked hole 31 both sides, shorten optical path distance, better reliability.Photoelectric push-button 4 can use any one photoelectric push-button of optical signal between blocking light radiated element 51 and light receiving element 52 when pressing existing.
