Abstract
The utility model relates to a wire-wound fixed resistor with an aluminium shell. The wire-wound fixed resistor comprises the aluminium shell, radiating grooves, a resistor main body and leading-out wires, wherein the aluminium shell is a hollow quadrangular drum-shaped shell; a plurality of horizontal radiating grooves are uniformly distributed in the upper side surface and the lower side surface of the aluminium shell at intervals; the radiating grooves penetrate through the outer surface of the aluminium shell; the resistor main body is horizontally and coaxially arranged in the aluminium shell, and an end plate is fixed in the aluminium shell at each of the two horizontal ends of the resistor main body in a sealing manner; the end parts of the resistor main body are connected with two leading-out wires by guide wires, and the two leading-out wires are horizontally arranged at an interval and extend out of the end plate on one side; two casting holes are formed in the middle of the end plate at one horizontal end of the metal shell at an interval and are communicated with each other; the metal shell outside the resistor main body is filled with slurry. The wire-wound fixed resistor has the advantages that due to adoption of the metal shell, the firm and durable effects are achieved, the power is high, the radiating performance is good and the installation is easy.
Description
Technical field
The utility model belongs to field of electronic devices, relates to resistor, especially a kind of aluminium shell wire-wound fixed resistor.
Background technology
Wirewound resistor forms in insulation framework with resistance filament winding.Resistance wire is general adopts the alloys such as nickel chromium triangle, copper-manganese with certain resistivity to make.Insulation framework is to make the various shapes such as tubular, flat by the materials such as metal of pottery, plastics, painting insulating layer coating.Resistance wire as required can coiling one deck on skeleton, also can coiling multilayer, or adopt noninductive winding etc.
Long term wear can cause that local wire diameter attenuates, and the extruding of external force, collision are also easy to cause resistance to damage, and along with electrical equipment is constantly to delicate structure development, its volume limitation is strong, and comparatively difficulty is installed.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and has that good volume is small and exquisite, clear in structure, the firm aluminium shell wire-wound fixed resistor of installation.
The technical scheme that the utility model adopts is:
A kind of aluminium shell wire-wound fixed resistor, comprise aluminium shell, radiating groove, resistance body and lead-out wire, it is characterized in that: the quadrangular cylindrical case that described aluminium shell is hollow, this uniform interval, upper and lower two sides of aluminium shell is shaped with many heatsink transverse grooves, and this radiating groove connects aluminium outer surface of outer cover; Aluminium enclosure transverse uniaxial is provided with resistance body, and in the aluminium shell of resistance body transverse ends, all sealing is fixed with an end plate; The end of described resistance body is connected with by wire the lead-out wire that two horizontal intervals arrange, and these two lead-out wires extend outside the end plate of a side; The interval, end plate middle part of the horizontal one end of described aluminium shell is shaped with two plug holes, and this plug hole is communicated with, and the aluminium enclosure outside resistance body is filled with slurry.
And the equal symmetry in described aluminium shell both sides, middle part, horizontal one end is shaped with a stopper slot.
And described aluminium outer surface of outer cover is evenly attached with layer protective layer.
Advantage of the present utility model and beneficial effect are:
1, this electric resistance structure is simple, easy for installation, resistance value is stable, exit size is less and be convenient to welded and installed, mechanical strength is high, resistance to welding good in thermal property, and also current overload ability is strong, excellent heat radiation performance, long service life, and this resistor has good moisture resistancely, can adapt to fast temperature and change and keep steady operation.
2, the utility model adopts metal shell, and sturdy and durable, power is large, perfect heat-dissipating, and be easy to install.
