Abstract
The utility model relates to the technical field of special resistor products, in particular to a cement resistor which comprises a resistor rod, an alloy wire, non-burning heat resistant cement and a ceramic casing. The alloy wire is connected with two ends of the resistor rod, the non-burning heat resistant cement wraps the alloy wire and the resistor rod, the ceramic casing packages the non-burning heat resistant cement, and terminals are arranged at two ends of the resistor rod and protrudes out of the ceramic casing. The cement resistor can be well applied to occasions where power and current are large and is excellent in safety.
Description
Technical field
The utility model relates to special resistance product technical field, relates in particular to a kind of cement resistor.
Background technology
The cement resistor device; Use the resistor of fire clay embedding exactly, be about to resistive conductor on no alkaline heat resisting porcelain spare, that the outside adds is heat-resisting, moisture-proof and resistant material protection are fixed; And put into square porcelain frame to the wire-wound resistor body, be sealed to form with the filling of special incombustible thermal cement.At present, the cement resistor device has two types of ordinary cement resistor and cement wirewound resistors.
Existing cement resistor, the application of the occasion big at some power, that electric current is big is still not fully up to expectations, and security performance also has much room for improvement.
Summary of the invention
The purpose of the utility model is to the deficiency of prior art a kind of cement resistor to be provided, and can be advantageously applied to the occasion that some power are big, electric current is big, and security performance is more superior.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of cement resistor, and it comprises resistor rod, alloy wire, incombustible thermal cement and porcelain shell, said alloy wire is connected in the two ends of resistor rod; The incombustible thermal cement wraps up said alloy wire and resistor rod; The porcelain shell encapsulates said incombustible thermal cement, and the two ends of said resistor rod are provided with terminal, and terminal is given prominence to said porcelain shell.
Said resistor rod is white rod or oxidation rod.
It also comprises support, and said porcelain shell is fixedly installed in support.
The utility model beneficial effect is: the described a kind of cement resistor of the utility model; It comprises resistor rod, alloy wire, incombustible thermal cement and porcelain shell; Said alloy wire is connected in the two ends of resistor rod, and the incombustible thermal cement wraps up said alloy wire and resistor rod, and the porcelain shell encapsulates said incombustible thermal cement; The two ends of said resistor rod are provided with terminal, and terminal is given prominence to said porcelain shell.Adopt the cement resistor of said structure, can be advantageously applied to the occasion that some power are big, electric current is big, and security performance is more superior.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the described a kind of cement resistor of the utility model, its structure is; It comprises resistor rod, alloy wire, incombustible thermal cement, porcelain shell 2 and support 1; Said alloy wire is connected in the two ends of resistor rod, and the incombustible thermal cement wraps up said alloy wire and resistor rod, and the porcelain shell encapsulates said incombustible thermal cement; The two ends of said resistor rod are provided with terminal 3, terminal 3 outstanding said porcelain shells.Alloy wire is connected in the two ends of resistor rod, and the incombustible thermal cement wraps up said alloy wire and resistor rod, the said incombustible thermal cement of porcelain shell 2 encapsulation, and said porcelain shell 2 is fixedly installed in support 1.As preferred embodiment, said resistor rod is white rod or oxidation rod.
The described a kind of cement resistor of the utility model; Its model is SQHG; Temperature range is-55 ℃～157 ℃, and rated electrical is 1W～60W, and rated value of resistance is 0.1 Ω～1.0k Ω; Can be widely used in the equipment such as power supply adaptor, stereo set, sound equipment frequency divider, instrument, instrument, television set, automobile; Play the effect that electric current is big, thermal diffusivity is fabulous that power is big, pass through, and the effect of in circuit, playing step-down, current limliting, the support 1 on the resistance shell makes things convenient for the client to install.The described a kind of cement resistor of the utility model is characterized in: one, have shatter-proof, moisture-proof, heat-resisting, good heat radiating, characteristics such as low price; Two, insulation is applicable to printed circuit board (PCB) fully; Three, accurate resistance value and life-saving are made in the joint electric welding then that winds the line on the porcelain rod; Four, high resistance adopts burning epithelium body (MO) to replace winding mode to process; Five, thermal endurance is excellent, and temperature coefficient of resistance is little, linearly changes; Six, the overburden of anti-the short time, low noise, resistance is no change year in year out; Seven, explosion-proof performance is good, shields.In sum, the described a kind of cement resistor of the utility model can be advantageously applied to the occasion that some power are big, electric current is big, and security performance is more superior.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
