Description
Technical field
The utility model is related to resistor fields, and in particular to a kind of field-discharge resistance device.
Background technology
Field-discharge resistance is to realize demagnetization purpose by changing the size of current of internal circuit.And field-discharge resistance carries out work
When making, resistor can generate substantial amounts of heat, if heat is excessively high, can seriously affect the normal work of resistor.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is intended to provide a kind of field-discharge resistance device, can improve resistance
The heat dissipation effect of device.
To achieve the above object, the utility model adopts the following technical solution：
A kind of field-discharge resistance device, the ceramic skeleton of multiple laid out in parallel including shell and installation inside the shell, Mei Getao
The two sides of porcelain body frame is both provided with metal film, and the silver electrode formed by silver paste sintering is provided on the metal film；It is described more
It is in parallel by metal lead wire between metal film on a ceramic skeleton arranged side by side；The both ends of the metal lead wire are extended to out of shell
Outside shell；Separation layer is provided between the adjacent ceramic skeleton, the separation layer is arranged to TPU rubber layers, the isolation
A large amount of heat emission holes are provided on layer；Gap between the ceramic skeleton and shell is provided with packing material.
Further, alloy conductive particle has been further included in silver paste material.
Further, a large amount of heat emission holes on the separation layer are that TPU rubber layers are punched by punch device.
Further, a diameter of 0.05-2mm of the heat emission hole.
The beneficial effects of the utility model are：
Multiple ceramic skeletons arranged side by side equipped with metal film are in parallel by metal lead wire in resistor so that access high-energy electricity
Metal film in parallel in resistor is absorbed when gushing, and improves the maximum of the operating voltage of resistor, is more effectively protected
Protect electronic equipment；Separation layer has preferable heat dissipation effect simultaneously, and more effectively resistor is protected in itself.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Reference numeral：1st, shell；2nd, ceramic skeleton；3rd, metal film；4th, silver electrode；5th, metal lead wire；6th, packing material.
Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further：
As shown in Figure 1, a kind of field-discharge resistance device, the ceramics of multiple laid out in parallel including shell 1 and in shell 1
Skeleton 2, the size dimension of multiple ceramic skeletons 2 are identical；The two sides of each ceramic skeleton 2 is both provided with metal film 3, the metal
The silver electrode 4 formed by silver paste sintering is provided on film 3, silver paste material has further included in addition to including 4 slurry of silver electrode
Alloy conductive particle can further improve the capacity for energy absorption of resistance mixed with the silver electrode 4 of alloy conductive particle.It is the multiple
It is in parallel by metal lead wire 5 between metal film 3 on ceramic skeleton 2 arranged side by side；Prolong out of shell 1 at the both ends of the metal lead wire 5
It reaches outside shell 1；The metal lead wire 5 extended to outside shell 1 is connected with circuit.It is provided between the adjacent ceramic skeleton 2
Separation layer, the separation layer are arranged to TPU rubber layers, a large amount of heat emission holes are provided on the separation layer；Wherein TPU is thermoplasticity
Elastic polyurethane body rubber, the TPU rubber layers have certain heat conductivility, in addition the ventilatory of heat emission hole, has very
Good heat dissipation effect.A large amount of heat emission holes on the separation layer are that TPU rubber layers are punched by punch device, described to dissipate
A diameter of 0.05-2mm of hot hole.The punch device has disclosed in the prior art, is not described in detail herein.Separately
Outside, the gap between the ceramic skeleton 2 and shell 1 is provided with packing material 6, and the packing material 6 is arranged to isolation material,
Ensure the normal work of resistor.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
