Abstract
General piece formula thermistor of high reliability, pin, the resistive body surface deposited protective layer is connected including resistive body, with resistive body, pin include that the external pin of cavity tubulose and cover locate the inner pin in the external pin, set up elastic bulge on the external pin inner wall, set up the upper and lower vertical arrangement's more than two or two recess on the inner pin outer wall, and protruding groove phase with corresponding resistive body 0 corresponds identically among the resistive body 1, the protruding arc that is the evagination, the recess is the arc of indent, protruding at least two, protruding equidistance setting on the same cross section of external pin, the concave surface of recess is the elasticity concave surface. The utility model has the characteristics of bear high temperature, high pressure and heavy current load, the commonality is stronger, reduce cost. Can extensively be arranged in equipment such as electron, electrical apparatus, electric power.
Description
Technical field
This utility model is related to critesistor, and in particular to a kind of general slice heat sensitive resistor of high reliability.
Background technology
Slice heat sensitive resistor includes chip NTC, PTC thermistor, and slice heat sensitive resistor is widely used, and applies chip
The product category of critesistor is various.At present the pin design comparison of slice heat sensitive resistor is single, enterprise's production chip temperature-sensitive electricity
The length of the pin of resistance is usually to be adjusted or the unification production of common standard according to being actually needed for specific product.If
It is adjusted according to being actually needed for specific product, needs Jing often to adjust, using different moulds, which enhances production cost,
Reduce production efficiency；And if carrying out unifying production according to a fixed standard length, to different product even different size
Same product for, using all very inconvenient.And, high temperature, excessively stream etc. easily damage critesistor.
Utility model content
To solve the defect of above-mentioned prior art, this utility model provides a kind of high reliability general slice heat sensitive resistor,
Suitable for the equipment such as great-power electronic, electrical equipment, electric power, highly versatile, low production cost.
The technical solution adopted in the utility model is：The general slice heat sensitive resistor of high reliability, including resistor main body and electricity
The pin of resistance body connection, the protective layer of resistor main body outer surface coating, it is characterised in that the pin includes hollow tubular
Outer pin and the interior pin being sheathed in outer pin, arrange elastic bumps on the outer pin inwall, arrange in interior pin outer wall
Two or more grooves up and down arranged vertically, it is described raised corresponding with the groove of corresponding file and be embedded in consistent manner
In groove.
More excellent, the raised circular arc for evagination, the groove is the circular arc of indent.
More excellent, described raised at least two, the projection is equidistantly positioned on the same cross section of outer pin.
More excellent, the concave surface of the groove is elastic concave surface.
The beneficial effects of the utility model：The outer pin of hollow tubular and the interior pin being sheathed in outer pin can bear
High temperature, high pressure and high current load, it is raised corresponding with the groove of corresponding file and in consistent manner be embedded in groove in, versatility is more
By force, reduces cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein：1. the projection 7. of pin 6. is recessed in the outer pin 5. of 2. pin of resistor main body, 3. protective layer 4.
Groove.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
As shown in figure 1, the general slice heat sensitive resistor of high reliability, including resistor main body 1 and the connection of resistor main body 1 are drawn
Foot 2, the protective layer 3 of the outer surface of resistor main body 1 coating, it is characterised in that the pin 2 includes the He of outer pin 4 of hollow tubular
The interior pin 5 being sheathed in outer pin 4, arranges elastic bumps 6 on the inwall of the outer pin 4, two are arranged on the outer wall of interior pin 5 and is arranged
Groove 7, often shows about three grooves 7 arranged vertically, and described raised 6 is corresponding with the groove 7 of corresponding file and in consistent manner
In embedded groove 7.Described raised 6 is the circular arc of evagination, and the groove 7 is the circular arc of indent.Described raised 6 have two,
Described raised 6 are equidistantly positioned on the same cross section of outer pin 4, and the concave surface of the groove 7 is elastic concave surface.
Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with this field skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification effect are similar, all should cover in this utility model
Protection domain in.
