Description

Technical Field

[0001] The utility model relates to the field of potentiometers, in particular to a potentiometer detection tooling. Background Art

[0002] A potentiometer is an adjustable electronic component, consisting of a resistor body and a rotating or sliding system. By changing the position of the contact on the resistor body, a voltage related to the position of the moving contact can be obtained. Potentiometers are mostly used as voltage dividers and are adjustable resistors widely used in electronic devices such as volume control of audio and receivers. Potentiometers can be classified into various types according to materials and the relationship between output and input voltage ratio and rotation angle. The main parameters include resistance value, tolerance, and rated power. Before leaving the factory, potentiometers need to be tested to ensure their normal performance, safety, and reliability.

[0003] The potentiometer detection tooling includes a detection body, and a fixture is arranged on the body. One end of the existing fixture is fixedly connected to the body, and mainly a single fixture is used to clamp the potentiometers to be detected one by one, which greatly limits the detection efficiency. On a high-production line, this low-efficiency clamping method will lead to an overly long detection process, affecting the production progress, and the detection causes greater wear and tear on the fixture than other devices, resulting in the fixture needing to be repaired and replaced relatively frequently.

[0004] Therefore, it is necessary to provide a new potentiometer detection tooling to solve the above technical problems. Summary of the Utility Model
