[0003] General ceramics are fragile and easy to wear, so ceramic resistors have poor wear resistance in actual use, which will affect their conductive properties. The reliability of ceramic resistors depends to a large extent on the mechanical properties of the resistor. The resistor body, lead caps and lead wires should all have sufficient mechanical strength. Matrix defects, lead cap damage or lead cracks will cause the resistor to fail. Therefore, it is necessary to increase the strength and wear-resistant protection function of the resistor ceramic white rod. In view of the above problems, this application proposes another technical solution to solve the problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A wear-resistant resistor ceramic white rod in this embodiment includes a resistor rod body 1, and wear-resistant protective mechanisms are arranged inside and outside the resistor rod body 1.

[0021] In this embodiment, the wear-resistant protection mechanism includes pins 2 fixedly installed on the left and right sides of the resistor rod body 1, and a wiring body 3 is fixedly installed on one side of the pin 2. The resistor rod body 1 is composed of a wear-resistant layer 101, a reinforcement layer 102, a waterproof layer 103, an anti-corrosion layer 104, a fire-proof layer 105, a porcelain tube layer 106 and a resistor body 107. The reinforcement layer 102 is arranged on the inner side of the wear-resistant layer 101.

[0022] A waterproof layer 103 is provided on one side of the reinforcing layer 102 away from the wear-resistant layer 101. The reinforcing layer 102 is made of glass fiber, which helps to increase the hardness and use strength of the device. The waterproof layer 103 is an acrylic paint layer, which facilitates waterproofing of the device.

[0023] In this embodiment, an anti-corrosion layer 104 is provided on the side of the waterproof layer 103 away from the reinforcing layer 102, and a fire-proof layer 105 is provided on the side of the anti-corrosion layer 104 away from the waterproof layer 103. The anti-corrosion layer 104 is coated with polyurethane, and the fire-proof layer 105 is made of flame-retardant rubber, which helps the fire-proof layer 105 to fireproof the device. A porcelain tube layer 106 is provided on the side of the fire-proof layer 105 away from the anti-corrosion layer 104, and the wear-resistant layer 101 is an epoxy resin coating, which helps to increase the wear resistance of the device and reduce scratches caused by bumps.

[0024] Among them, the wear-resistant layer 101 fully covers the reinforcing layer 102, the waterproof layer 103, the anti-corrosion layer 104, the fire-proof layer 105 and the porcelain tube layer 106, which helps to use the wear-resistant layer 101 for covering and increase the wear-resistant function. A resistor 107 is provided on the side of the porcelain tube layer 106 away from the fire-proof layer 105. The pin 2 is made of alloy copper. The resistor 107 is separately connected to the pin 2, which helps to connect the pin 2 to electricity. The porcelain tube layer 106 is made of ceramics, and the resistor 107 is made of silicon carbide.

[0025] It should be noted that the wear-resistant resistor ceramic white rod, through the wear-resistant protection mechanism set up, uses the wear-resistant layer 101 to prevent the device from being damaged by friction, collision, scratches, etc., and uses the reinforcement layer 102 to help increase the strength and hardness of the device and avoid damage to the device caused by bumps and extrusions. Under the action of the waterproof layer 103 and the anti-corrosion layer 104, the internal resistor 107 can be prevented from getting water in and corrosion caused by water ingress can be avoided. The fireproof layer 105 can be used to perform fireproof and heat-insulating treatment on the device, and the resistor 107 can be protected more effectively, which helps to increase the service life of the device.

[0026] The working principle of the above embodiment is:

[0027] When using the wear-resistant white ceramic resistor rod, the pins 2 can be first welded to the left and right sides of the resistor rod body 1, and the wiring body 3 can be fixed on the outside of the pin 2, and then the device can be used. During use, the wear-resistant layer 101 is on the surface of the resistor rod body 1, which can prevent the device from being damaged by friction and collision and scratches. The use of the reinforcement layer 102 helps to increase the strength and hardness of the device and avoid damage to the device caused by bumps and squeezing. Under the action of the waterproof layer 103 and the anti-corrosion layer 104, the internal resistor 107 can be prevented from getting water in and corrosion caused by water ingress. The fireproof layer 105 can be used to perform fireproof and heat-insulating treatment on the device, and the resistor 107 can be protected more effectively, which greatly improves the protection function of the device and helps to increase the service life of the device.
