Description

Technical Field

[0001] The utility model relates to the technical field of resistors, in particular to an impact-resistant aluminum shell resistor. Background Art

[0002] Aluminum shell resistors are made of aluminum alloy with heat dissipation grooves on the surface. They are small in size and high in power. They are resistant to high temperatures and have strong overload capacity. They are also weather-resistant, high-precision, standard low-induction resistors, high stability, and strong architecture. They have good flexibility and multiple combination options, are good for mechanical protection, and are easy to install and use.

Sealing plates are embedded at both ends of the aluminum shell tube, and a foam pad is attached to the side wall of the sealing plate facing the inside of the aluminum shell tube. The foam pad can absorb impact force when the filler is laterally squeezed, reducing the pressure caused by the filler on the sealing plate, and a thin film is added to the side wall of the foam pad close to the filler to prevent the filler from entering the interior of the foam pad. When the pressure disappears, the foam pad recovers itself, so that the resistor can cope with multiple impacts.

The lower part of the inner surface of the U-shaped bearing frame 21 is symmetrically fixedly connected with a T-shaped plate 23, which can facilitate the installation and disassembly of the external protection mechanism 3.

[0025] In order to achieve the purpose of protecting the aluminum shell tube 1 from external impact, refer to Figure 2 The outer protection mechanism 3 includes a well-shaped fixing frame 31, and a plurality of rubber balls 32 are fixedly connected at intervals on the side of the outer surface of the well-shaped fixing frame 31 away from the outer surface of the U-shaped bearing frame 21, which can buffer and absorb external impact force, and the well-shaped fixing frame 31 is fixedly connected to the outside of the U-shaped bearing frame 21.

[0026] In order to achieve the purpose of absorbing the impact force suffered by the aluminum shell tube 1, refer to Figure 3 The inner protection mechanism 6 includes a rectangular pressure reducing tube 61, and baffles 62 are symmetrically fixedly connected to the left and right ends of the outer surface of the rectangular pressure reducing tube 61, which can seal the filler 63 and fix the two connecting pieces 72 at the same time. The inner cavity of the rectangular pressure reducing tube 61 is filled with an appropriate amount of filler 63, which can support the two resistor cores 71 and conduct the heat generated by them. The outer surface of the rectangular pressure reducing tube 61 is fixedly connected to the inner surface of the aluminum shell tube 1.

[0027] In order to achieve the purpose of connecting to the outside world and making it work, refer to Figure 3 The resistor component 7 includes two resistor cores 71 , and the left ends of the outer surfaces of the two resistor cores 71 are fixedly connected with connecting pieces 72 , and the two resistor cores 71 are placed inside the filler 63 .
