The novel thread resistor comprises a ceramic tube (1), a leading-out terminal (2) arranged on the ceramic tube (1), and resistance wires (3) winded on the outer surface of the ceramic tube (1) and connected with the leading-out terminal (2), wherein the resistance wires (3) are circular spring-shaped and are helically winded on the outer surface of the ceramic tube (1). The novel thread resistor disclosed by the utility model can be extensively applied in the field of radiating resistors.
Description
Technical field
The utility model relates to a kind of Novel threaded resistor.
Background technology
Resistor adopts earthenware as skeleton, two leading-out terminals have been fixed on the earthenware, and twined the alloy resistance wire of the bandlet wave-like that contacts with leading-out terminal on the earthenware surface, and have at its surface-coated one deck fire-retardant, the insulating coating of high-temperature stability, easy for installation, has the good heat radiating ability, can be used for the frequency converter braking, servo system is in the electric loops such as power supply.And at present, research and development and input along with powerful device, this requires then further to improve for resistor, this is because if the increased power of resistor then certainly will will improve the requirement of heat dispersion, otherwise, be difficult to satisfy the normal use of resistor, easily cause the life-span of resistor short, therefore, this just exists certain inconvenience.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides that a kind of good heat dissipation effect, large, the anti-overload capacity of power are strong, the Novel threaded resistor of long service life.
The technical scheme that the utility model adopts is: the resistance wire that the utility model comprises earthenware, be arranged on leading-out terminal and the outer surface that is wrapped in described earthenware on the described earthenware and be connected with described leading-out terminal, described resistance wire is the coil component spring shape, the outer surface that is wrapped in described earthenware of spiral.
Further, be provided with the resistance wire holding tank on the described earthenware, described resistance wire holding tank is made of two acclive inclined-planes of tool and middle groove, leaves the gap between the outer surface of described groove and described resistance wire.
Further, described earthenware is the housing of inner hollow, is provided with several gas ports on the described resistance wire holding tank.
Further, described several gas ports are arranged on surface relative on the described earthenware.
Further, described screw thread resistor also comprises the carrier base that is positioned at described earthenware both sides, the support bar that is positioned at described earthenware, and described support bar is provided with air vent hole by the described carrier base of nut check on the described carrier base.
The beneficial effects of the utility model are: because the described resistance wire in the utility model is the coil component spring shape, the outer surface that is wrapped in described earthenware of spiral, compared with prior art, its length is long than the bandlet wave-like, simultaneously, its external surface area major part is exposed in air, so the utility model good heat dissipation effect, large, the anti-overload capacity of power is strong, the life-span is long.
