Description

Technical Field

[0001] This invention relates to the field of resistor technology, and more specifically to an irregularly shaped strip resistor. Background Technology

[0002] Currently, there are various forms of resistor element assemblies used in high-power resistors. Especially in the area of ​​high-power, high-energy, low-resistance resistors, some manufacturers directly create circuits by punching different cracks into stainless steel resistor plates, using them directly as resistor element assemblies. This method results in sharp corners at the ends of the cracks, poor resistance to high-current surges, inability to continuously carry loads, and unreliable performance. Because the cracks are directly punched into the resistor element to form a current-carrying circuit, the sharp corners at the ends of the cracks easily lead to current accumulation after a large current passes through, causing the resistor element to burn out and rendering the resistor unusable.

[0003] Then came the integrated strip resistor. However, once the existing resistor strip is installed, it is difficult to deform and cannot be adapted to the usage environment. Its flexibility needs to be improved. Summary of the Invention

[0004] In view of the above-mentioned technical problems in the existing technology, the present invention provides an irregularly shaped strip resistor.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A non-circular strip resistor is provided, comprising an upper base and a lower base, with multiple sets of support rods standing between the upper and lower bases. Multiple layers of resistor strips are arranged longitudinally along the length of the support rods. Each layer of resistor strips includes multiple resistor strips arranged laterally from the inside out. Each resistor strip is in a closed-loop curved shape, thus forming a series of concave portions and convex portions. The support rods are provided with multiple slots, and the concave portions and convex portions of the resistor strips are respectively embedded in different slots. The support rods corresponding to the convex portions can move in the inward and outward directions under external force to change the degree of protrusion of the convex portions.

[0007] Specifically, the support rod includes a fixed rod corresponding to the concave part and a movable rod corresponding to the outer arch part. The two ends of the fixed rod are fixed to the upper seat and the lower seat, and the two ends of the movable rod are slidably installed on the upper seat and the slide seat.

[0008] Specifically, the upper and lower seats are each provided with an elongated hole, and the end of the moving rod can slidably engage with the elongated hole.

[0009] Specifically, the side of the fixed rod is provided with multiple slots along the length direction, and multiple fixed rods are stacked in layers, so that the slots of adjacent fixed rods form a support hole through which the inner concave part of the resistor bar passes.

[0010] Specifically, the moving rod includes a rod body and multiple support parts. The multiple support parts are arranged along the length of the rod body, and each support part is provided with multiple support grooves. The outer arch of multiple resistor strips in each layer of resistor strip group can be movably embedded in the support groove.

[0011] Specifically, a blower mechanism for driving the moving rod is also provided between the upper and lower seats.

[0012] Specifically, the blower mechanism includes a high-pressure main pipe and multiple high-pressure branch pipes. The two ends of the high-pressure main pipe are fixed to the upper and lower seats respectively. The high-pressure branch pipes are arranged along the length of the high-pressure main pipe. Multiple blind holes are provided on the back of the multiple moving rods. The high-pressure branch pipes are inserted into the blind holes, and there is a distance between the port of the high-pressure branch pipe and the bottom of the blind hole. The high-pressure branch pipes corresponding to different moving rods can be selectively opened and closed.

[0013] Specifically, the upper seat, lower seat, and support rod are all made of mica.

[0014] The beneficial effects of this invention are:

[0015] The present invention discloses an irregularly shaped strip resistor. When in use, a sufficiently large force can be applied to the support rod of the outer arch according to the usage environment, such as space requirements, temperature, wind direction, etc., so that the support rod under force can drive the corresponding outer arch to arch to a greater extent. After the external force is released, the strength of the resistor strip is sufficient to maintain the adjusted shape, thus making it more adaptable and flexible. Attached Figure Description

[0027] The present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0028] This embodiment features an irregularly shaped strip resistor, such as... Figures 1 to 6 As shown, the system includes an upper seat 11 and a lower seat 12. Multiple sets of support rods 2 stand between the upper seat 11 and the lower seat 12, arranged in a near-circular pattern. Along the length of the support rods 2, longitudinally separated multi-layered resistor strip groups 3 are arranged. Each resistor strip group 3 includes multiple resistor strips 31 (three in this example) arranged laterally from the inside out. Each resistor strip 31 is in a closed-loop curved shape, thus forming a series of concave portions 311 and convex portions 312. The support rods 2 are provided with multiple slots 21, and the concave portions 311 and convex portions 312 of the resistor strips 31 are respectively embedded in different slots 21. The support rods 2 corresponding to the convex portions 312 can move in the inward and outward directions under external force to change the degree of protrusion of the convex portions 312.

[0029] During use, depending on the environment, such as space requirements, temperature, and wind direction, a sufficiently large force can be applied to the support rod 2 of the outer arch 312. This allows the supported rod 2 to cause the corresponding outer arch 312 to arch further. After the external force is released, the strength of the resistor strip 31 is sufficient to maintain the adjusted shape, thus enhancing its adaptability and flexibility. It is understandable that, with the total length of a resistor strip 31 remaining constant, moving the support rod 2 only changes its bending shape. If some outer arches 312 become more prominent, then other outer arches 312 will inevitably become less prominent. The purpose is to change the petal shape of the resistor strip 31, making it more prominent in areas with larger installation space, higher airflow, and lower temperatures.

[0030] In this embodiment, the support rod 2 includes a fixed rod 22 corresponding to the concave portion 311 and a movable rod 23 corresponding to the outer arch portion 312. The two ends of the fixed rod 22 are fixed to the upper seat 11 and the lower seat 12, and the two ends of the movable rod 23 are slidably mounted on the upper seat 11 and the slide. The upper seat 11 and the lower seat 12 are respectively provided with elongated holes 10, and the ends of the movable rod 23 are slidably engaged with the hole walls of the elongated holes 10.

[0031] In this embodiment, the side of the fixed rod 22 is provided with a plurality of slots 21 along the length direction, and the multiple fixed rods 22 are stacked and arranged so that the slots 21 of adjacent fixed rods 22 form a support hole through which the inner concave portion 311 of the resistor strip 31 passes with a gap fit, so that the resistor strip 31 can slide in the support hole during adjustment.

[0032] Specifically, the moving rod 23 includes a rod body 231 and multiple support parts 232. The multiple support parts 232 are arranged along the length direction of the rod body 231. Each support part 232 is provided with multiple support grooves (a form of the slot 21). The outer arch 312 of the multiple resistor strips 31 of each layer of resistor strip group 3 is movably embedded in the support groove.

[0033] In practice, the protrusion of each outer arch 312 of the resistor strip 31 can be adjusted by manually pushing the moving rod 23. In this embodiment, for automatic adjustment and heat dissipation, a blower mechanism for driving the moving rod 23 is also provided between the upper seat 11 and the lower seat 12. Specifically, the blower mechanism includes a high-pressure main pipe 4 and multiple high-pressure branch pipes 5. The two ends of the high-pressure main pipe 4 are fixed to the upper seat 11 and the lower seat 12 respectively. The high-pressure branch pipes 5 are arranged along the length of the high-pressure main pipe 4. Multiple blind holes 233 are provided on the back of the multiple moving rods 23. The high-pressure branch pipes 5 are inserted into the blind holes 233, and there is a distance between the port of the high-pressure branch pipe 5 and the bottom of the blind hole 233. In this way, the high-pressure gas of the high-pressure main pipe 4 is blown to the blind hole 233 through the high-pressure branch pipes 5, which can drive the moving rod 23 to move. The outer diameter of the high-pressure branch pipe 5 is smaller than the inner diameter of the blind hole 233. When the moving rod 23 moves, the high-pressure branch pipe 5 moves relative to the blind hole 233. The gas flowing out after impacting the blind hole 233 can also cool the resistor strip 31. The high-pressure branch pipe 5 corresponding to different actuators 23 is equipped with an electric valve, which can be selectively opened and closed. The so-called "high pressure" in this case is not a limitation on the magnitude, but rather refers to the pressure relative to ordinary air pressure. The air pressure in this case is required to drive the actuator 23 to move. Of course, when no driving is needed, low-pressure air can also be used to achieve a cooling effect.

[0034] Specifically, the upper seat 11, the lower seat 12, and the support rod 2 are all made of mica.
