Description

Technical Field

[0001] This utility model relates to the field of alloy resistor technology, and in particular to a packaged alloy resistor with a heat dissipation structure. Background Technology

[0002] Alloy resistors are resistors that use alloys as the current medium. They are characterized by low resistance, high precision, low temperature coefficient, resistance to surge current, and high power. They are widely used in precision instruments, military products, aerospace electronics, new energy photovoltaic products, automobiles, and other fields.

[0003] Alloy resistors are one of the preferred components for sampling current. With the development of technology, alloy resistors are also required to have higher power performance. However, alloy resistors currently generate a lot of heat during long-term use and the heat dissipation rate is too slow, which affects the quality of the resistor and the heat dissipation effect. As a result, alloy resistor products on the market have a high operating temperature. High temperature not only directly affects the normal performance of alloy resistors and affects their later use, but also shortens the lifespan of the resistor and causes economic losses.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0021] Combination Figures 1 to 4 As shown, the specific characteristics of this packaged alloy resistor with a heat dissipation structure are described in detail below:

[0022] The packaged alloy resistor with a heat dissipation structure includes a metal guide post 1 and a heat dissipation assembly. A resistor body 2 is mounted on the surface of the metal guide post 1. Fixing caps 3 are fixedly mounted on both ends of the resistor body 2. An encapsulation layer 4 is fixedly connected to the surface of the resistor body 2 and the two fixing caps 3. L-shaped metal support rods 5 are fixedly connected to both ends of the metal guide post 1. Welded circular plates 6 are fixedly connected to the opposite ends of the two L-shaped metal support rods 5. The heat dissipation assembly includes two heat dissipation aluminum fins 8, two positioning key blocks 9, and two hexagonal prism nuts 12. Installation holes are provided on both ends of the metal guide post 1. The mounting slide 7 has two heat sink aluminum fins 8 that are slidably connected inside the two mounting slide 7. The two positioning key blocks 9 are fixedly connected inside the metal guide post 1. The two positioning key blocks 9 are located on the front and rear surfaces inside the mounting slide 7. The front and rear surfaces of the heat sink aluminum fins 8 are provided with positioning keyways 10. The two positioning key blocks 9 are slidably opened inside the two positioning keyways 10. The two mounting slide 7 have the same structure inside. The left and right ends of the metal guide post 1 are provided with threaded slots 11. The two hexagonal prism nuts 12 are threadedly installed on the left and right ends of the metal guide post 1.

[0023] During installation, the worker mounts the resistor body 2 onto the surface of the metal guide post 1, then fixes the iron caps 3 at both ends of the resistor body 2. After that, a fixed encapsulation layer 4 is formed on the surface of the resistor body 2 and the two iron caps 3. At this point, the resistor body is initially encapsulated and fixed on the metal guide post.

[0024] Workers can solder two 6s onto the circuit board and support them with two 5s against 1s. The two heat sink aluminum fins 8 are then placed into the mounting grooves 7 opened at the left and right ends of the metal guide post 1. At this time, since the front and rear surfaces of the heat sink aluminum fins 8 have positioning keyways 10, and the metal guide post 1 is fixedly connected to the front and rear surfaces of the mounting grooves 7, the positioning keyways 9 will slide into the positioning keyways 10 respectively, playing a positioning and guiding role, ensuring that the heat sink aluminum fins 8 are installed in the correct direction and are stable.

[0025] Hexagonal nuts 12 are threaded into the threaded slots 11 at both ends of the metal guide post 1. By tightening the hexagonal nuts 12, the heat sink 8 is firmly fixed in the mounting groove 7, completing the installation of the heat dissipation component. The heat sink 8 has good thermal conductivity, which can quickly conduct the heat generated by the resistor body 2 away, increase the heat dissipation area, and accelerate the heat dissipation speed. The cooperation between the positioning key block 9 and the positioning keyway 10, as well as the fixing of the hexagonal nuts 12, ensures the stability and reliability of the heat sink 8 installation, so that the heat dissipation effect can be continuously and stably performed. Through efficient heat dissipation, the temperature of the resistor during use is reduced, avoiding the adverse effects of high temperature on the resistor performance, thereby ensuring the stability and reliability of the resistor in later use, and also extending the service life of the resistor and reducing the economic losses caused by resistor damage.
