Abstract
The utility model discloses a kind of folded-edge grid-type resistor, including resistor disc, the grid crack structure of several equidistant dislocation arrangements is offered on the resistor disc, the grid crack structure makes the current trend on the resistor disc in serpentine；It has been respectively coated by mica strip on the opposite two sides of the resistor disc, has been fixed outside the mica strip by bound edge.The resistor provided in the utility model cracks folded-edge structure, and the flow direction of electric current is in serpentine around to the total length of current direction increases at this time, than bar resistor device, can preferably alleviate its ability to bear.Additionally, due to a plurality of grid crack structure is offered, so that the surface area of entire resistor disc increases, it is more conducive to radiate in this way.In use, the resistor can directly serial or parallel connection in circuit, be not necessarily to supports support, structure is simple.
Description
Technical field
The utility model relates to a kind of circuit components, specially a kind of folded-edge grid-type resistor.
Background technique
Resistor is the indispensable component of each class of electronic devices, with global consumer electronics, communication, automobile, calculating
The rapid development in the fields such as machine, the requirement to resistor are also continuously increased.
As shown in Figure 1, existing resistor is mostly the resistor of bar shaped.The resistor of bar shaped has to individually when in use
With a supports support, structure is complicated, and manufacturing cost also rises.As shown in Fig. 2, bar resistor device is after powered up, electric current compared with
Intensive trend is straight line, and total length is shorter, and ability to bear is poor.Based on the above situation, how to provide that a kind of structure is simple, heat dissipation
The folded-edge grid-type resistor that effect is good, ability to bear is good becomes the important topic of those skilled in the art's research.
Utility model content
The problem of for background technique, the utility model provide a kind of folded-edge grid-type resistor.
To achieve the above object, the utility model provides the following technical solutions: a kind of folded-edge grid-type resistor, including electricity
Piece is hindered, the grid crack structure of several equidistant dislocation arrangements is offered on the resistor disc, the grid crack structure makes the resistor disc
On current trend be in serpentine；
It has been respectively coated by mica strip on the opposite two sides of the resistor disc, has been fixed outside the mica strip by bound edge.
As the utility model a preferred technical solution, the bound edge is made of stainless steel material.
As the utility model a preferred technical solution, mounting hole is offered on the resistor disc.
Compared with prior art, the utility model has the beneficial effects that.
Detailed description of the invention
Fig. 1 is bar resistor device structural schematic diagram in the prior art；
Fig. 2 is bar resistor device current trend schematic diagram in the prior art；
Fig. 3 is a kind of folded-edge grid-type resistor structure schematic diagram provided by the utility model；
Fig. 4 is that a kind of folded-edge grid-type resistor current provided by the utility model moves towards schematic diagram；
In figure: 1- resistor disc；2- grid crack structure；3- mica strip；4- bound edge；5- mounting hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 3 and Fig. 4 are please referred to, the utility model provides a kind of folded-edge grid-type resistor, including resistor disc 1, the electricity
The grid crack structure 2 of several equidistant dislocation arrangements is offered on resistance piece 1, the grid crack structure 2 makes the electric current on the resistor disc 1
Trend is in serpentine；
It has been respectively coated by mica strip 3 on the opposite two sides of the resistor disc 1, has been consolidated outside the mica strip 3 by bound edge 4
It is fixed.
The resistor provided in the utility model cracks folded-edge structure, the flow direction of electric current in serpentine around to,
The total length of current direction increases at this time, than bar resistor device, can preferably alleviate its ability to bear.Additionally, due to offering
A plurality of grid crack structure 2 is more conducive to radiate in this way so that the surface area of entire resistor disc 1 increases.In use, the resistor can be with
Direct serial or parallel connection is not necessarily to supports support in circuit, and structure is simple.
In the specific implementation process, the bound edge 4 is made of stainless steel material.
In the specific implementation process, mounting hole 5 is offered on the resistor disc 1, is easily installed fixation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
