Description

Technical Field

[0001] The utility model relates to the technical field of resistors, in particular to a resistor which is easy to fix. Background Art

[0002] Resistors are generally called resistors in daily life. It is a current limiting element. After connecting the resistor to the circuit, the resistance of the resistor is fixed, usually with two pins. It can limit the current through the branch it is connected to. The resistance value of the resistor element is generally related to temperature, material, length, and cross-sectional area. The physical quantity that measures the influence of temperature on the resistor is the temperature coefficient, which is defined as the percentage change in resistance value when the temperature rises by 1°C. The main physical characteristic of the resistor is that it converts electrical energy into thermal energy. It can also be said that it is an energy-consuming element. When current passes through it, it generates internal energy. Some existing resistors are not easy to fix when used, especially when they are connected to some electrical components installed in cables or round rods. It is more troublesome to operate.

[0033] Specifically, an outer wall of the limiting rod 21 is fixedly connected to an assembly plate 31 , and one side of the assembly plate 31 is fixedly connected to a protective shell 32 .

[0034] Furthermore, by turning the first bidirectional screw rod 22, the moving blocks 23 can be controlled to move closer to or farther away from each other, so that the fixed point position of the clamping block 27 can be adjusted, and then the second bidirectional screw rod 26 can be turned by rotating the swivel 24 so that the two clamping blocks 27 can clamp the cable, thereby applying force through the cables at both ends to fix them, so that the resistor body 42 will not easily detach from the two ends of the cable after docking. The limit rod 21 prevents the moving block 23 from rotating, and the limit groove 25 can reinforce and limit the clamping block 27 to prevent it from tilting to one side.

[0035] Example 2

[0036] Reference Figures 1 to 4, which is the second embodiment of the utility model, and is based on the previous embodiment. The auxiliary component 4 includes a dust filter plate 41, which is fixedly connected to both ends of the inner wall of the protective shell 32, and the inner wall of the dust filter plate 41 is fixedly installed with a resistor body 42. The side wall of the protective shell 32 is rotatably connected to a central shaft 43, one end of which is fixedly connected to a first bevel gear 44, and the outer wall of the central shaft 43 is fixedly connected to a wind blocking plate 411.

[0038] Furthermore, by cooperating with each other, the central rotating shaft 43 and the wind blocking plate 411 are blown by natural wind to drive the wind blocking plate 411 to drive the central rotating shaft 43 to rotate, and then the first bevel gear 44 drives the second bevel gear 45 to rotate, so that the rotating rod 47 can drive the driving gear 48 to rotate, and the driving gear 48 then drives the driven gear 410 to rotate, and the driven gear 410 will drive the cooling fan 49 to rotate. Since the second bevel gear 45 is respectively engaged with the two sides of the first bevel gear 44, the two second bevel gears 45 on both sides rotate in opposite directions, and the cooling fan 49 is installed in opposite directions, so that the cooling fan 49 at one end will continuously inhale the outside air, and the cooling fan 49 at the other end will discharge the air in the protective shell 32, and then the air flow rate of the clamp block will take away the heat generated by the resistor body 42 to achieve the heat dissipation effect.

[0039] Working principle: By turning the first bidirectional screw rod 22, the moving blocks 23 can be controlled to move closer or farther away from each other, so that the fixed point position of the clamping block 27 can be adjusted, and then the second bidirectional screw rod 26 can be turned by rotating the swivel ring 24 so that the two clamping blocks 27 can clamp the cable, so that the cables at both ends are subjected to force and fixed, so that the resistor body 42 will not be easily separated from the two ends of the cable after docking, the limit rod 21 prevents the moving block 23 from rotating, and the limit groove 25 can reinforce the clamping block 27 to prevent it from tilting to one side, and the central shaft 43 and the wind blocking plate 411 cooperate with each other, so that the natural wind blows the wind blocking plate 411 to drive the central shaft 43 to rotate, thereby making the first A bevel gear 44 drives the second bevel gear 45 to rotate so that the rotating rod 47 can drive the driving gear 48 to rotate, and the driving gear 48 then drives the driven gear 410 to rotate, and the driven gear 410 will drive the cooling fan 49 to rotate. Since the second bevel gears 45 are respectively engaged with the two sides of the first bevel gear 44, the two second bevel gears 45 on both sides rotate in opposite directions, and the cooling fans 49 are installed in opposite directions, so that the cooling fan 49 at one end will continuously inhale the outside air, and the cooling fan 49 at the other end will discharge the air in the protective shell 32, and then the air flow rate of the clamp will take away the heat generated by the resistor body 42 to achieve the heat dissipation effect.
