Abstract
The utility model relates to an improved computer key structure, in particular to a key structure for a computer keyboard. The computer key structure is accomplished by adopting the following technical scheme that key-press boards with key structures are arranged on two vertically overlapped flexible thin-film printed circuit boards, pressing plates are pressed on the key-press boards, key caps for the key structure convexly protrude out of holes of the pressing plates, and elastic lugs for the key structure convexly protrude on conducting strips for the two flexible thin-film printed circuit boards. A scissors type support is eliminated, therefore, the thickness of the computer is greatly reduced, the cost of the products is lowered, the original structure and the effect can be well replaced by utilizing the own elasticity of the key-press boards for the key structure, and the computer key structure has good market prospect.
Description
Technical field:
The utility model relates to a kind of press-key structure of computor-keyboard.
Background technology:
The society progress, make people's work and the life in touch electronic product more and more.And people generally are the processing of carrying out data or literal aspect by the button on the electronic product.Shown in accompanying drawing 1～2, Fig. 1 is the schematic diagram of existing computor-keyboard 10, and Fig. 2 is the cutaway view of computor-keyboard 10 along tangent line 2-2.Computor-keyboard 10 includes a plastic casing 12, and a plurality of press-key structure 14 is fixed in the plastic casing 12.
Press-key structure 14 includes two upper and lower folded mutually flexible film printed circuit board (PCB)s 16,18, the bottom side 20 of the flexible film printed circuit board (PCB) 16 on upper strata respectively is provided with a conducting strip 24,26 with the uper side surface 22 of the flexible film printed circuit board (PCB) 18 of lower floor, one flexible film sheet 28 is located between two printed circuit board (PCB)s 16,18 with stickup or alternate manner, one scissor scaffold bracket 13 is located on the printed circuit board (PCB) 16, and one support base plate 17 and be located at printed circuit board (PCB) 18 times, required bracing force when being used to provide pressing keys structure 14.Flexible film sheet 28 is provided with a hole 30 between conducting strip 24,26, and its thickness makes and produces a spacing between the conducting strip 24,26.
Press-key structure 14 includes a keycap 32 in addition, one scissor support 34 is fixed on keycap 32 on the flexible film printed circuit board (PCB) 16 in the mode that can press up and down, and one flexible member 36 be located between keycap 32 and the flexible film printed circuit board (PCB) 16, be used for flexibly to upper support keycap 32.When keycap 32 was pressed downwards, the bottom of flexible member 16 can press the conducting strip 24 of flexible film printed circuit board (PCB) 16 downwards, it is produced with the conducting strip 26 of flexible film printed circuit board (PCB) 18 be electrically connected.
Can learn from above-mentioned press-key structure 14, keycap 32 relies on scissor support 34 to prop up and fall, but the trend for present computer development is " gently ", " approaching " and low-cost requirement, scissor support 34 makes computer thickness increase, and scissor support 34 is made up of several findings, a lot of operations in the assembling process, the production cost height.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of very thin computer press-key structure is provided.
The utility model is achieved by the following technical solution: two upper and lower folded mutually flexible film printed circuit board (PCB)s are provided with the keypad that has press-key structure, covered pressing plate on the keypad, the keycap of keypad protrudes out outside the hole of pressing plate, and the elastic projection of keypad protrudes out on two soft printed circuit board conducting strips.
The utility model has reduced the thickness of computer greatly owing to removed scissor support, has reduced the cost of product, and has utilized the elasticity of the keypad self of press-key structure, can well replace original structure and effect, has good market prospects.
Description of drawings:
Accompanying drawing 1 is the schematic diagram of existing computor-keyboard 10
Accompanying drawing 2 is the cutaway view of computor-keyboard 10 along tangent line 2-2
Accompanying drawing 3 is the utility model cutaway view
Embodiment:
See accompanying drawing 3, the utility model includes two upper and lower folded mutually soft printed circuit boards 16,18, the bottom side 20 of the flexible film printed circuit board (PCB) 16 on upper strata respectively is provided with a conducting strip 24,26 with the uper side surface 22 of the flexible film printed circuit board (PCB) 18 of lower floor, one flexible film sheet 28 is located between two printed circuit board (PCB)s 16,18 with stickup or alternate manner, flexible film sheet 28 is provided with a hole 30 between conducting strip 24,26, its thickness makes and produces a spacing between the conducting strip 24,26, and circuit is in off-state when keeping button to be failure to actuate.Two upper and lower folded mutually flexible film printed circuit board (PCB)s 16,18 are provided with the keypad 1 that has press-key structure, covered pressing plate 3 on the keypad 1, the keycap 111 of keypad 1 protrudes out outside the hole 31 of pressing plate 3, and the elastic projection 11 of keypad 1 protrudes out on the conducting strip 24,26 of two flexible film printed circuit board (PCB)s 16,18.
Pressing plate 3 can be one-body molded with keypad 1, also can be adhered to one another.
Keycap 111 is the hard plastic material, can be adhered to one another with keypad 1.
Keypad 1 is a plastic cement material.
Pressing plate 3 is a metal material.
When using the utility model, press keycap 111 with hand, because it is that rubber-like silica gel or other soft rubber material are made for a keypad 1, the elastic projection 11 that keycap 111 drives keypad 1 protrudes out in the hole 30 of flexible film sheet 28, and conducting strip 24,26 is contacted with each other, produce electrical connection; If remove the pressure on the keycap 111, under the effect of elastic force, keycap 111 rises automatically, makes elastic projection 11 rise, and conducting strip 24,26 disengages mutually, finishes an action that impacts button.
