Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a testing tool for potentiometer multichannel connectors. Background Technology

[0002] The connectors on a potentiometer primarily serve as electrical connections and mechanical fixation. Through conductive contacts, the connectors physically and electrically connect the potentiometer to a printed circuit board or other circuit components, ensuring the flow of current or signals. This allows the potentiometer to adjust its resistance and output corresponding voltage or current. High-quality connectors have low and stable contact resistance, reducing signal loss or interference. Their insertion and extraction forces and mechanical lifespan design ensure reliable contact even after multiple operations. Connectors are typically encapsulated in a housing to prevent environmental factors such as dust and moisture from affecting the potentiometer's internal contacts, enhancing overall structural stability and reducing malfunctions caused by vibration or impact. The standardized interfaces of connectors facilitate quick installation, removal, and replacement of potentiometers, simplifying circuit board assembly and subsequent maintenance processes. Testing tools are frequently used to check whether the connectors on potentiometers are functioning correctly.

[0003] However, traditional testing tools have the following drawbacks: Test tools are susceptible to high-frequency interference, contact resistance drift, and bandwidth limitations, which can lead to measurement deviations. Specifically, the contact resistance fluctuations on the test tool are affected by factors such as material oxidation and environmental temperature and humidity cycles, which may distort the signal integrity assessment. Insufficient bandwidth or lack of calibration of a single-channel probe can attenuate high-frequency signal components, resulting in inaccurate measurements. Summary of the Invention

Specifically, the contact resistance fluctuations on the test tool are affected by factors such as material oxidation and environmental temperature and humidity cycles, which may distort the signal integrity assessment; insufficient bandwidth or lack of calibration of a single-channel probe will attenuate high-frequency signal components, resulting in inaccurate measurements.

[0010] Furthermore, both clamping mechanisms include a fixed platform and a lower pressure frame. A telescopic screw is threadedly connected to the middle of the top of the fixed platform, and the top of the telescopic screw is movably connected to one side of the bottom of the lower pressure frame.

[0011] Furthermore, locking holes are provided on both sides of the top of the fixed platform, and the bottom of the fixed platform is fixedly connected to the clamp fixing groove. The user can tighten the screw through the locking hole to fix the fixed platform in the clamp fixing groove.

The movable end of the miniature cylinder is fixedly connected to the bottom end of the connecting platform. The miniature cylinder performs telescopic movement, pulling the connecting platform from the bottom to adjust the height of the lower pressure frame, which is equivalent to a telescopic screw. The lower pressure frame and the fixed platform cooperate with each other to clamp and fix the potentiometer from both sides.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By setting up test components, the multi-channel design allows for the simultaneous testing of multiple connectors or channels, reducing single test time. The test components feature independent channel control and high-precision differential wiring components to achieve high-precision parameter measurement.
