Description
Technical field
The utility model relates to a kind of circuit elements device, particularly a kind of cylindrical shape resistor.
Background technology
Resistor is the indispensable components and parts of each class of electronic devices, and along with the develop rapidly in fields such as global consumer electronics, communication, automobile, computer, its requirement to resistor also constantly increases.Problems such as existing cylindrical shape resistor exists manufacturing process many, and volume is bigger, and the effective area of use is little.Based on above-mentioned situation, how to provide a kind of simple and compact for structure, assembling easily, cylindrical shape resistor that volume is little, become the important topic of those skilled in the art's research.
Summary of the invention
The purpose of this utility model provided a kind of simple in structure, assembling easily, resistor that volume is little, solved the deficiencies in the prior art part.
The purpose of this utility model is achieved in that a kind of cylindrical shape resistor, comprising: resistive element, fagging, porcelain spare is characterized in that: the outside of described fagging is connected with porcelain spare, and the outside of porcelain spare is wound with resistive element, and the resistive element coiled is circular.
Described resistive element is a siderochrome aluminium bandlet.
Described fagging is a galvanized sheet.
The thickness of described galvanized sheet is 1-5mm.
The circle diameter of described resistive element coiled is not more than 60mm.
Described resistive element is provided with connector.
The utility model has the advantages that: simple and compact for structure, assembling is easy, and volume is little, and is in light weight, has the working temperature height, long service life, and the surface loading height, temperature coefficient of resistance is little, and safety and reliability are good, and interchangeability is good, saves operation and material.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is a left view of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among Fig. 1 and Fig. 2, a kind of cylindrical shape resistor comprises: resistive element 1, fagging 2, porcelain spare 3 is characterized in that: the outside of described fagging 2 is connected with porcelain spare 3, and the outside of porcelain spare 3 is wound with resistive element 1, and resistive element 1 coiled is circular.
Described resistive element 1 is a siderochrome aluminium bandlet, and it is a kind of high-resistance electrothermic alloy, has the working temperature height, long service life, and the surface loading height, temperature coefficient of resistance is little, and proportion is little, and safety and reliability are good, series of advantages such as interchangeability.Resistive element 1 is not limited to siderochrome aluminium bandlet, also can adopt other high-resistance electrothermic alloies.
Described fagging 2 is a galvanized sheet, and punching press is made, and no longer needs flanging to handle, and saves operation and material.
The thickness of described galvanized sheet is 1-5mm, present embodiment adopt 3mm galvanized sheet.
The circle diameter of described resistive element 1 coiled is not more than Φ 60mm, compares with domestic conventional cylinder type resistor, and effective area is bigger, and porcelain spare face radian is little, and with to contact circular siderochrome aluminium flat big, structure is compact more.
Described resistive element 1 is provided with connector 4, uses for client's wiring.
During use, the cylindrical shape resistor is used for 50Hz/60Hz, electric pressure 660V and direct voltage to the circuit of 440V, mainly as the startup of motor, the braking and the usefulness of speed governing.External circuit is connected on the connector of cylindrical shape resistor, can use, and is convenient and easy.
Below only expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Advantage of the present utility model: simple and compact for structure, assembling is easy, and volume is little, and is in light weight, has the operating temperature height, long service life, and the surface loading height, temperature-coefficient of electrical resistance is little, and safety and reliability are good, and interchangeability is good, saves operation and material.
