Abstract
The utility model discloses a novel piezo -resistor electrode, including body and pin, this body is including based bulk layer, the first layer of aluminizing, copper plate and the second layer of aluminizing, this based bulk layer has an embedded slot, and this based bulk layer is ceramic material, and fixed part and connecting portion that this pin is connected including integrated into one piece, fixed part inlay in embedded slot fixedly, should firstly aluminize the layer completely the parcel live in surface and fixed part of based bulk layer, this copper plate wraps up first surface of aluminizing the layer completely, this second layer parcel surface of copper plate firmly completely of aluminizing, these connecting portion stretch out the second and aluminize outside the layer. Through adopting ceramic material as based bulk layer to be provided with embedded slot, the fixed part of pin can combine firmly with based bulk layer, and the cooperation is provided with first aluminize layer, copper plate and the second layer of aluminizing, has replaced the sheetmetal structure of tradition, and this overall product hardness is enough, is convenient for install, and the metal use amount is few, does benefit to reduce cost.
Description
Technical field
This utility model is related to varistor art, refers in particular to a kind of new piezoresistance electrode.
Background technology
" varistor " is a kind of resistance device with nonlinear wind vibration, is mainly used in when circuit bears overvoltage
Voltage clamp is carried out, absorbs unnecessary electric current to protect Sensitive Apparatuses.English name is " Voltage Dependent
Resistor " is abbreviated as " VDR ", or is called " Varistor ".The resistor material of piezoresistor is quasiconductor, so
It is a kind of semiconductor resistor." Zinc Oxide " for using in a large number now（ZnO）Piezoresistor, its material of main part
There is bivalent element zinc（Zn）With hexad oxygen（O）Constituted.So from from the perspective of material, zinc oxide varistor is
A kind of " II-VI race's oxide semiconductor ".
It is presently used for varistor Top electrode and is generally overall sheet metal material, quality is softer, assembling inconvenience, and
Cost is also higher, therefore, it is necessary to be improved to the electrode of current varistor.
The content of the invention
In view of this, for the disappearance of prior art presence, its main purpose is to provide a kind of new this utility model
Piezoresistance electrode, its can effectively existing varistor electrode install inconvenience and high cost problem.
For achieving the above object, this utility model is using such as purgation technical scheme：
A kind of new piezoresistance electrode, includes body and pin；The body includes body layer, first aluminizes
Layer, copper plate and the second aluminium coated；The body layer has an embedding slot, and the body layer is ceramic material, and the pin includes one
The fixed part and connecting portion of body formed connection, fixed part is embedded in embedding slot fixed, the fully wrapped around firmly main body of first aluminium coated
The outer surface and fixed part of layer, the outer surface of fully wrapped around firmly the first aluminium coated of the copper plate, second aluminium coated is fully wrapped around
The firmly outer surface of copper plate, the connecting portion is stretched out outside the second aluminium coated.
Preferably, the body is disc-shaped structure.
Preferably, the flush of the surface of the fixed part and body layer.
Preferably, the pin is copper sheet.
This utility model has compared with prior art clear advantage and beneficial effect, specifically, by above-mentioned technology
Scheme understands：
By being used as body layer using ceramic material, and embedding slot is provided with, the fixed part of pin can be combined with body layer
Firmly, the first aluminium coated, copper plate and the second aluminium coated are equipped with, the sheet metal structure of tradition is instead of, this product is whole
Body hardness enough, is easily installed, also, metal usage amount is few, beneficial to reduces cost.
More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings
This utility model is described in detail.

Specific embodiment
Refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of this utility model, include
Body 10 and pin 20.
The body 10 includes body layer 11, the first aluminium coated 12, the aluminium coated 14 of copper plate 13 and second；The body layer 11
With an embedding slot 101, embedding slot 101 is extended from the center of body layer 11 to outer peripheral edge, and the body layer 11 is ceramic material, should
Pin 20 includes the fixed part 21 and connecting portion 22 for being integrally formed connection, and fixed part 21 is embedded in embedding slot 101 fixed, and this
The outer surface and fixed part 21 of the fully wrapped around firmly body layer 11 of one aluminium coated 12, fully wrapped around firmly the first aluminium coated of the copper plate 13
12 outer surface, the outer surface of the fully wrapped around firmly copper plate 13 of second aluminium coated 14, connecting portion 22 stretches out the second aluminium coated
Outside 14.
In the present embodiment, the body 10 is disc-shaped structure.The surface of the fixed part 21 and the table of body layer 11
Face is concordant, and the pin 20 is copper sheet.
When using, body 10 is embedded on the accommodating draw-in groove that the substrate of varistor pre-sets.
Design focal point of the present utility model is：By being used as body layer using ceramic material, and embedding slot is provided with, pin
Fixed part can be firmly combined with body layer, be equipped with the first aluminium coated, copper plate and the second aluminium coated, instead of tradition
Sheet metal structure, this product integral hardness enough, is easily installed, also, metal usage amount is few, beneficial to reduces cost.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and can not by any way be construed to the restriction to this utility model protection domain.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by need not paying performing creative labour,
These modes are fallen within protection domain of the present utility model.
