Abstract
The utility model provides a take spherical contact surface piezoresistor at ring shape platform edge, its characterized in that: the upper surface of the cylindrical body of piezoresistor is spherical bulge, and the lower surface is the spherical recess branch, respectively has a ring shape platform in edge surperficial from top to bottom. The problem of the piezoresistor edge of general spherical contact surface easy to be damaged, easily produce point discharge is solved. It is difficult damaged to have the edge, advantages such as difficult production point discharge.
Description
Technical field
This utility model relates to a kind of resistor, a kind of spheric contact surface piezoresistor with annular platform edges specifically.
Background technology
At present, existing piezoresistor is all cylindrical on the market, and when multi-disc stacks, its contact surface is circular flat, and the contact surface between each is less big, thus through-current capability is also less big.The piezoresistor of follow-on ball type of contact surface, it is possible to when multi-disc stacks, utilizes its ball type of contact surface, makes the contact surface between each as far as possible big, but owing to concave surface has sharp-pointed edge, there is edge cracky, be easily generated the shortcomings such as point discharge.
Summary of the invention
The purpose of this utility model is in that to provide a kind of spheric contact surface piezoresistor with annular platform edges, it is possible to eliminates the edge that concave surface is sharp-pointed, has edge not cracky, be not likely to produce the advantages such as point discharge.
This utility model includes the annular terrace part of piezoresistor cylindrical body portion, spheric bossing, spheric recess and edge, be the technical scheme is that the upper surface of described piezoresistor cylindrical body is spheric bossing, lower surface is spheric recess, and all there is an annular platform in upper and lower surface edge.
The beneficial effects of the utility model are in that: by the configuration of technique scheme, constitute the piezoresistor of a kind of spheric with annular platform edges contact, solve the piezoresistor edge cracky of general ball type of contact surface, the problem being easily generated point discharge.There is edge not cracky, be not likely to produce the advantages such as point discharge.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Shown in Fig. 1: the upper surface of piezoresistor cylindrical body 1 is spheric bossing 2, lower surface is spheric recess 3, and the edge in upper and lower surface is respectively arranged with an annular platform 4.
