Description

Technical Field

[0001] The utility model relates to the technical field related to ceramic resistor rods, in particular to a bolt wear-resistant ceramic resistor rod. Background Art

[0002] Resistors are generally referred to as resistors, which generally refer to all electronic or motor accessories used to generate resistance. They are two-terminal electronic components made of conductive materials, have a certain structural form, and can limit the flow of current in the circuit. Ceramic resistors are one of the commonly used resistors in electronic circuits. Their production and design use high-precision technology to ensure that the accuracy of the resistance value is as high as one ten-thousandth or more, which can meet the high requirements of the circuit for the resistance value. Ceramic combination resistors are composed of a mixture of finely ground insulators and conductors, compressed into a cylindrical shape.

[0003] However, since ceramics are fragile and easy to wear, the ceramic resistor rods will be worn out due to friction during long-term adjustment during use, which will make the ceramic resistor rods have poor wear resistance and affect their conductive properties. Utility Model Content

[0004] In order to solve the defects in the prior art, the utility model provides a bolt wear-resistant ceramic resistor rod.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a wear-resistant ceramic resistor rod for bolts, comprising a ceramic resistor rod, support brackets are fixed at both ends of the ceramic resistor rod, a first joint is arranged at one end of the ceramic resistor rod, a metal rod is rotatably arranged between the two support brackets, a second joint is arranged at one end of the metal rod, a metal ring is sleeved on the surface of the ceramic resistor rod, a metal ball which is rolled inside the metal ring and fits the ceramic resistor rod, a conductive rod is fixed on the surface of the metal ring, and the top of the conductive rod is connected to the metal rod through a sliding block.

[0007] As a preferred technical solution of the utility model, the surface of the metal rod is provided with threads, and the sliding block is threadedly installed on the outer surface of the metal rod.

[0008] As a preferred technical solution of the utility model, an insulating handle is fixed to the end of the metal rod.

[0009] As a preferred technical solution of the utility model, a mounting plate with mounting holes is provided at the bottom of the support bracket.

[0010] As a preferred technical solution of the utility model, the support bracket and the mounting plate are fixed via a shock-absorbing pad.

[0011] The beneficial effects of the utility model are:

[0012] 1. This type of bolt wear-resistant ceramic resistor rod is equipped with a metal ring, a metal ball, a conductive rod and a metal rod. The metal ring and the metal ball slide on the surface of the ceramic resistor rod. The conductive rod and the metal rod can adjust the resistance size. The metal ball contacts the surface of the ceramic resistor rod.
