Rush the every profession and trade such as network, laser field.
In alternating current system, electric current by resistor it is constant under conditions of, the inductance of resistor is bigger, the sense of resistor
It is anti-higher, so cause RC low-frequency channels or LC high-frequency circuit middle impedance values to change, it is impossible to meet design requirement.For upper
Operating mode is stated, technical staff reduces the inductance of resistor using the structure connection mode for changing resistor at present, but only by changing
Becoming connection mode can increase resistor volume, and production cost steeply rises, in addition current power equipment it is overall towards it is intelligent,
The direction of miniaturization is developed, and the mode of volume increase not only can cause resistor use scope to be limited, while also be difficult in adapt to go
The high speed development of industry.
The content of the invention
Existing resistor induction reactance is high, bulky technical problem in order to solve, and the present invention provides a kind of miniaturization
The resistor of zero induction reactance.
The technical solution of the utility model is：A kind of resistor, it is characterized in that：Including support plate, propping up
The edge insulator slotware that fagging both sides are set and the resistance wire being wrapped on edge insulator slotware；The initial end of the resistance wire is by propping up
Fagging one end is spirally wound to the support plate other end, reversely continues winding again until returning after reaching the other end of support plate
Return the initial end of resistance wire.
Further, above-mentioned edge insulator slotware buckle on the supporting plate, the edge insulator slotware material for heat-stable ceramic or
Mica.
Further, above-mentioned edge insulator slotware includes the lug boss and concave part being arranged alternately successively.
Further, the surface of above-mentioned lug boss is provided with the wire casing for resistance wire winding, and the surface of the concave part is set
It is equipped with the wire casing for resistance wire winding.
Further, the initial end of above-mentioned resistance wire is spirally wound from support plate one end to the support plate other end
When, resistance wire is wrapped on the concave part of edge insulator slotware；Reversely continue to twine again after resistance wire reaches the support plate other end
Around when, resistance wire is wrapped on the lug boss of edge insulator slotware.
Further, the initial end of above-mentioned resistance wire is spirally wound from support plate one end to the support plate other end
When, resistance wire is wrapped on the lug boss of edge insulator slotware；Reversely continue to twine again after resistance wire reaches the support plate other end
Around when, resistance wire is wrapped on the concave part of edge insulator slotware.
The utility model has the advantage of：
(1) the utility model is by current path detour on divided resistance wire, and the vector sum of each pair electric current is zero, magnetic
Induction is zero, therefore mutual inductance is not produced between each pair current path, farthest reduces the inductance of resistor.
(2) not only insulation performance is high for resistor provided by the utility model, and resistance to elevated temperatures is strong, and radiating rate is fast,
Ensure resistance wire effectively by electric current, resistance is without inductance, it can be ensured that product safety is reliably run, while small, production
Cost is low.

Embodiment
Embodiment one
Referring to Fig. 1, the present embodiment is a kind of resistor, its structure includes support plate 3, is symmetrical arranged in 3 both sides of support plate
Edge insulator slotware 2 and the resistance wire 1 that is wrapped on edge insulator slotware 2.
The initial end of resistance wire 1 is spirally wound from support plate one end to the support plate other end, reaches support plate 3
Bypassed after the other end and reversely continue to wind again after the stud 4 in the middle part of the end, until returning to the initial end of resistance wire.Referring to figure
2, edge insulator slotware 2 is that the section being buckled on the supporting plate is the arcuate structure of semicircle, and the surface of edge insulator slotware 2 is provided with confession
The wire casing 5 of resistance wire winding.Edge insulator slotware 2 is arranged to semicircular arc structure can farthest coordinate resistance wire 1
Spiral winding, makes resistance wire 1 to be seamlessly transitted on edge insulator slotware 2, reach marginal position when can also with insulate card slot
The surface perfection of part 2 is tangent, the stress influence without being subject to 2 corner of edge insulator slotware.
Edge insulator slotware 2 is used to support resistance wire 1, and support plate 3 is used to support edge insulator slotware 2, makes overall fixation.Support
3 material of plate is metal, mica or ceramics, the preferably small mica material of inductance and ceramic material.2 material of edge insulator slotware is heat-resisting
Ceramics or mica, the clamping of edge insulator slotware 2 provide heat dissipation channel, are conducive to 1 quick heat radiating of resistance wire.Cross is wound
Structure makes current path detour, and on the resistance wire 1 of intersection, the vector sum of each pair electric current is zero, magnetic induction intensity zero, therefore
Mutual inductance is not produced between each pair current path, farthest reduces the inductance of resistor, inductance value is as low as ignored, completely
Meet design requirement.
Embodiment two
Referring to Fig. 3, the present embodiment and the difference of embodiment one are that the surface of edge insulator slotware 2 is provided with successively
Alternate lug boss 6 and concave part 7.Lug boss 6 and concave part 7 are the arcuate structures that radial section is semicircle, lug boss
Section radius are more than the section radius of the concave part.The surface of lug boss 6 is provided with the wire casing 5 for resistance wire winding.
When the initial end of resistance wire is spirally wound from support plate one end to the support plate other end, if resistance wire
It is wrapped on the concave part of edge insulator slotware；So when reversely continuing winding again after resistance wire reaches the support plate other end,
Resistance wire is wrapped on the lug boss of edge insulator slotware.
Vice versa, when the initial end of resistance wire is spirally wound from support plate one end to the support plate other end,
If resistance wire can be wrapped on the lug boss of edge insulator slotware；It is so anti-again after resistance wire reaches the support plate other end
To when continuing winding, resistance wire is wrapped on the concave part of edge insulator slotware.
The present embodiment is by setting the lug boss alternateed and concave part can be by the resistance wire phase of the different hands of spiral
Mutually isolation, avoids producing mutual space interference.
