Based on above-mentioned purpose, the present invention adopts the following technical scheme that：
The present invention provides a kind of fusing piezoresistor certainly, including：Body, the first pin, the second pin, connector, absolutely
Edge shrapnel, one end of first pin and the second pin are connected to the conduction region in two faces of body, body surface
Covered with insulating layer, the other end is made of low melting point metal material, and leaves through hole, coordinates with the through hole of wire connection terminal by being connected
Part is fixedly connected, and body one side extends in parallel out two insulation shrapnels, respectively opposition parallel with the first pin and the second pin.
In one embodiment, the connecting mode of first pin, the second pin and wire connection terminal include riveting or
It is bolted.
In one embodiment, first pin, the union end of the second pin are made of 140 ° of scolding tin.
In one embodiment, the insulation shrapnel is touched with this body by integral forming, the other end with connector bottom connection.
The present invention's is coupled instead of original welding from fusing piezoresistor pin end with wire connection terminal by connector
Mode, pin end are made of special 140 ° of scolding tin of low melting point metal material, and the heat produced when current is excessive reaches this
140 ° of the fusing point of metal material will melt pin, so as to be disconnected with terminals, the setting for the shrapnel that insulate makes after fusing
Two terminals being capable of quick separating.

To explain.
Please refer to Fig.1 and Fig. 2, the present invention provide a kind of fusing piezoresistor certainly, should include from fusing piezoresistor：
Body 1, the first pin 2, the second pin 3, connector 4, insulation shrapnel 5,2 and second pin 3 of the first pin
One end be connected to the conduction region in 1 two faces of body, 1 surface of body is covered with insulating layer, the first pin 2 and second
The other end of pin 3 is made of low melting point metal material, and 2 and second pin 3 of the first pin includes three sections, is respectively
First section, the second section and the 3rd section, first section are located at the conduction region in 1 insulating layer of body, the exposure of the second section
In outside, it is made of low melting point metal material for connecting the first section and the 3rd section, the 3rd section and leaves through hole, three
A section is integrally formed, and the through hole of the through hole and wire connection terminal 6 of the 3rd section matches, and two terminals overlap by even
Fitting 4 is fixedly connected, which passes through pin with exposing one section after the through hole of wire connection terminal 6 and being touched with insulation shrapnel 5,
Two insulation shrapnels 5 extend in parallel out length not less than pin by 1 one side of body, and respectively with the first pin 2 and second
3 parallel opposition of pin.After connector 4 passes through through hole, insulation shrapnel can be compressed and be allowed to deform upon, when the 3rd section of pin
Fuse, the active force that insulation shrapnel 4 recovers deformation makes connector 4 upward, and then pin is divided rapidly with wire connection terminal 6
From.
Further, the connecting mode of first pin 2, the second pin 3 and wire connection terminal 6 includes riveting or bolt connects
Connect, it is more easy to operate compared to conventional welding.
Preferably, first pin 2, union end i.e. the 3rd section of the second pin 3 are made of 140 ° of scolding tin, the firstth area
Section and the material of the second section are not limited.
Further, the insulation shrapnel 5 is integrally formed with body 1, and the other end is in contact with 4 base plane of connector.
When connector 4 passes through through hole, 4 bottom plane contact of connector is to insulation shrapnel 5, when pin has been coupled with wire connection terminal
Cheng Shi, insulation shrapnel 5 are further deeply deformed upon due to 4 bottom of connector, and insulation shrapnel 5 is no longer parallel with pin,
Shape has a certain degree.
The present invention's is coupled instead of original welding from fusing piezoresistor pin end with wire connection terminal by connector
Mode, pin end are made of special 140 ° of scolding tin of low melting point metal material, and the heat produced when current is excessive reaches this
140 ° of the fusing point of metal material will melt pin, so as to be disconnected with terminals, the setting for the shrapnel that insulate makes after fusing
Two terminals being capable of quick separating.
The above is only some embodiments of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
