Abstract
The utility model provides a high resolution acceleration and deceleration sensor, including an inside of making by insulating material be inclosed hollow cambered surface groove's insulating casing the cambered surface in hollow cambered surface groove in inlay and have flexible circuit board and annotate a little mercury, along with the increase and decrease of speed, mercury can along the cambered surface freely removes around on flexible circuit board to switch on and break off adjacent contact, produce corresponding status signal. The invention can be used for sensing acceleration or deceleration, centrifugal force, angle variable, horizontal positioning, displacement, touch, collision, inclination, inversion and the like.
Description
Technical field
The present invention relates to a kind of acceleration/deceleration sensor, particularly a kind of high resolving power acceleration/deceleration sensor.
Background technology
The patent No. is the anxious deceleration regime sensor of ZL9814167.1, because its contact is the design of single needle formula, be subject to the production technology limitation, can't accomplish dense arrangement, be difficult to improve the resolution of sensor, and this explained hereafter efficient is low, complex procedures, be difficult for realizing the production of robotization streamlined, particularly the contact resistance of this kind technology is big, and the sensitivity of mercury and degree of freedom are restricted, and causes the product of equal technological process, identical service condition, the retarded velocity that is detected but deviation is quite different, be that consistency of product is poor, qualification rate is on the low side, can only use in low grade products.
Summary of the invention
One of purpose of the present invention: simplify production technology, improve resolution, realize the streamlined operation, enhance productivity.
Two of purpose of the present invention: reduce contact resistance, improve the mercury flexibility ratio, thereby obtain nearly 100% qualification rate.
To achieve these goals, the present invention proposes a kind of high resolving power acceleration/deceleration sensor, comprise that an inside of being made by insulating material forms the insulation crust of an airtight hollow arch groove, described arch groove has a cambered surface and is inlaid with flexible PCB, in described hollow arch groove, fill the conduction coasting body, variation along with speed, the conduction coasting body can be along described cambered surface in arch groove, freely move before and after on the circuit board, on described circuit board, be provided with a plurality of conductive contacts and the described enclosure that goes between, as extraction electrode, when the conduction coasting body walks to the other end by an end of circuit board, conducting and disconnect adjacent contact successively.
Figure is further described the present invention below in conjunction with symbol
Description of drawings
Among the figure: 1 is conduction coasting body (as: mercury); 2 is flexible double-sided PCB cable-through hole; 3 is cambered surface; 4 is insulation crust; 5 is the double-sided flex circuit plate.
Embodiment
In type ultrathin flexible multiconductor circuit board 5 is embedded in the plastic housing that has cambered surface 34 of sealing, in its cavity, injects a little mercury as the moving contact coasting body.
Principle of work
Increasing or subtracting along with speed, conduction coasting body 1 is synchronously moved forward and backward by horizontality, the adjacent contacts of difference conducting and disconnecting circuit plate 5, wherein, cable-through hole 2 is that the common of reverse side is guided to the front, that is to say whole of the upper end of hole reverse side, as a common, thereby obtain high resolution.
Because mercury is than great, and auto-convergence characteristic and electric conductivity are good, and therefore, conduction coasting body 1 first-selection is a mercury, also can be other special conducting liquid.
Claims (4)
1, a kind of high resolving power acceleration/deceleration sensor, it is characterized in that: an inside of being made by insulating material forms the insulation crust 4 of an airtight hollow arch groove, described arch groove has a cambered surface 3 and is inlaid with circuit board 5, in described hollow arch groove, fill conduction coasting body 1, variation along with speed, conduction coasting body 1 can be along described cambered surface 3 in arch groove, freely move before and after on the circuit board 5, on described circuit board 5, be provided with a plurality of conductive contacts and go between described shell 4 outsides, as extraction electrode, at conduction coasting body 1 when walking to the other end by circuit board 5 one ends, conducting and disconnect adjacent contact successively.
2, high resolving power acceleration/deceleration sensor according to claim 1, the arrangement that it is characterized in that circuit board 5 and contact thereof are to prolong cambered surface 3 vertically to be provided with.
3, high resolving power acceleration/deceleration sensor according to claim 1 and 2 is characterized in that described circuit board is a flexible PCB, serves as better with the double-faced flexible thin plate.
4, high resolving power acceleration/deceleration sensor according to claim 1 is characterized in that its coasting body can be any type of special conducting liquid, is best with mercury.
