Description

One is exempted to weld plug type keyboard

Technical field:

This utility model relates to computer peripheral equipment technical field, refers in particular to one and exempts to weld plug type keyboard.

Background technology:

It is fixing that existing keyboard structure typically all uses welding manner, i.e. button base and keyboard lines plate to be connected by welding manner, this mode button except key-press shell detachably in addition to, button base and switch shaft etc. are non-removable state.When wherein certain button malfunction or fault, whole keyboard can be caused to use, need integral replacing, the most not only waste cost but also waste material resources, to for the user that user especially keyboard usage amount, utilization rate are high, need the biggest cost payout.And, the cleaning of existing machinery keyboard is cumbersome, and time one length is easy for dust stratification, is easily caused product the longest for service life.

Utility model content:

The purpose of this utility model is the weak point overcoming existing product, it is provided that one is exempted to weld plug type keyboard.

The technical solution adopted in the utility model is: one is exempted to weld plug type keyboard, and it includes several mechanical keys that keyboard drain pan, keyboard face-piece, the pcb board that is arranged between keyboard drain pan with keyboard face-piece are connected with pcb board；Mechanical key has button base, the switch shaft being arranged on button base and covers the key-press shell above switch shaft, and there is on button base the down-set pin connected with pcb board；Wherein: described pcb board is provided with the pin conductive hole that several are corresponding with the pin on the button base of the mechanical key of relevant position；Form on described keyboard face-piece several for button bases of mechanical keys pass by key window；The both sides of the button base in each mechanical key form an Elastic buckle respectively, the outside of each Elastic buckle has the card buckle side inconsistent with the button lower window edge on described keyboard face-piece, the outer end of each Elastic buckle protrudes from by the upper surface of key window, and forms the most laterally projecting barb at its outer end.

Having conductive copper in each described pin conductive hole, conductive copper connects with pcb board, and conductive copper inwall has the conduction of a pair inwardly projecting and sticks up foot.

On the lateral surface of each described Elastic buckle, the lower section of card buckle side form guiding surface.

This utility model, owing to using plug type structure, has the following advantages, one, and keyboard assembles without weld job, not only favourable to energy-conserving and environment-protective, favourable to workers ' health, and packaging efficiency improves；They are two years old, when wherein certain button malfunction or fault, can individually this button be replaced, and without changing whole keyboard, therefore can greatly reduce the cost of user, be especially suitable for relatively big to keyboard usage amount and use net coffee, Internet bar or the network game fan that frequency is higher；Commonly used person can be changed different mechanical keys as required, such as, need sound or noiseless etc., to user more DIY enjoyment, meet its use demand；They are three years old, it is also possible to pull down button and keyboard is carried out comprehensive cleaning, to ensure operating temperature and to extend its service life.

Accompanying drawing illustrates:

Fig. 1 is the partial sectional view of this utility model mechanical keyboard；

Fig. 2, Fig. 3 are the partial enlarged drawing in Fig. 1 at A and at B respectively.

Detailed description of the invention:

Below in conjunction with specific embodiments and the drawings, this utility model is further illustrated.

As shown in Figure 1-Figure 3, described in the utility model is that one is exempted to weld plug type keyboard, and it includes several mechanical keys 4 that keyboard drain pan 1, keyboard face-piece 2, the pcb board 3 that is arranged between keyboard drain pan 1 with keyboard face-piece 2 are connected with pcb board 3；The switch shaft 42 there is in mechanical key 4 button base 41, being arranged on button base 41 and covering key-press shell 43 above switch shaft 42, and there is on button base 41 the down-set pin 44 connected with pcb board 3；Wherein: described pcb board 3 is provided with the pin conductive hole 31 that several are corresponding with the pin 44 on the button base 41 of the mechanical key 4 of relevant position；Form on described keyboard face-piece 2 several for button bases 41 of mechanical keys 4 pass by key window 21；Each by key window 21 is installed a mechanical key 4；The both sides of the button base 41 in each mechanical key 4 form an Elastic buckle 411 respectively, the outside of each Elastic buckle 411 have with on described keyboard face-piece 2 by key window 21 times along inconsistent card buckle side 4111, the outer end of each Elastic buckle 411 protrudes from and forms the most laterally projecting barb 4112 at the upper surface by key window 21, and its outer end.The bottom of button base 41 has downward projection of locating dowel (not identifying in figure), corresponding with the hole, location on pcb board 3.

On the lateral surface of each described Elastic buckle 411, the lower section of card buckle side 4111 form guiding surface 4113, it is simple to pass through during button base 41 grafting on keyboard face-piece 2 by key window 21.

Utilize this card buckle side 4111 with by under this side of key window 21 along inconsistent, after making button base 41 and pcb board 3 grafting, in the absence of external forces, button base 41 is limited at by key window 21, will not loosen and drop out, thus realize the grafting of mechanical key 4；And when mechanical key 4 is extracted by needs, have only to the tweezers hook-shaped by, clamp at the barb 4112 of two Elastic buckles 411, first Elastic buckle 411 is inwardly clamped, its card buckle side 4111 is departed from by 21 times edges of key window, then recycle the barb effect of the hook portion of tweezers and the barb 4112 of Elastic buckle 411, firmly Elastic buckle 411 is pulled up, button base 41 and the entirety such as switch shaft thereon 42, key-press shell 43 can be extracted.

Having conductive copper 32 in each described pin conductive hole 31, conductive copper 32 connects with pcb board 3, and conductive copper 32 inwall has the conduction of a pair inwardly projecting and sticks up foot 321；Pin 44 on button base 41 is in flat tip shape, it is easy to grafting, pair of conductive sticks up foot 321 in bending dorsad, after the pin 44 of mechanical key 4 inserts in the conductive copper 32 of pin conductive hole 31, foot 321 can be stuck up with conduction to conflict, make conduction stick up foot 321 to extrude to both sides, utilize conduction to stick up elastically keeping of foot 321 and stably contact conduction with pin 44.

Certainly, in the present embodiment, mechanical key 4 also includes the mechanism such as switch shaft back-moving spring and key-press shell restoring lever, and these belong to known technology, the most do not illustrate or identify, and also repeat no more at this.

In sum, this utility model, owing to using plug type structure, has the following advantages, one, and keyboard assembles without weld job, not only favourable to energy-conserving and environment-protective, favourable to workers ' health, and packaging efficiency improves；They are two years old, when wherein certain button malfunction or fault, can individually this button be replaced, and without changing whole keyboard, therefore can greatly reduce the cost of user, be especially suitable for relatively big to keyboard usage amount and use net coffee, Internet bar or the network game fan that frequency is higher；Commonly used person can be changed different mechanical keys as required, such as, need sound or noiseless etc., to user more DIY enjoyment, meet its use demand；They are three years old, it is also possible to pull down button and keyboard is carried out comprehensive cleaning, to ensure operating temperature and to extend its service life.
