Description

Technical Field

[0001] The utility model relates to the technical field of power testing, in particular to a clamp for terminal testing. Background Art

[0002] In the electronics manufacturing industry, testing the insertion and extraction forces of terminals is crucial for ensuring product quality and reliability. Traditional terminal testing methods often rely on manual labor, which is not only inefficient but also difficult to guarantee the accuracy and consistency of test results. With the development of automated testing technology, more and more companies are adopting automated testing equipment to replace manual testing. However, existing automated testing equipment still suffers from poorly designed test chucks for terminal testing. This can easily lead to loosening or damage of terminals during testing, and the test chucks are complex to operate, making it difficult to complete testing tasks quickly and accurately. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a terminal testing chuck which has a compact structure, is easy to operate, has stable and reliable testing performance, and is widely compatible with testing terminals of various thicknesses.

[0004] In order to achieve the above objectives, the utility model adopts such a terminal testing chuck, comprising a base, a movable clamp movably connected to the base, a terminal fixing block fixedly connected to the base and arranged opposite to the movable clamp, and a locking rod assembly movably connected to the base, the base is provided with a fixed shaft, the movable clamp is provided with a first axial hole matching the fixed shaft, the terminal fixing block is provided with a terminal fixing groove, the terminal fixing groove is used to fix the terminal to be tested, the base is also provided with a locking shaft located at one end of the terminal fixing block, the movable clamp and the terminal fixing block are both provided with notches at corresponding positions, the locking rod assembly is provided with a second axial hole matching the locking shaft, the locking rod assembly is connected to the locking shaft through the second axial hole, and extends out of the space between the terminal fixing block and the movable clamp, and the length exceeds the boundary of the movable clamp and is located outside the movable clamp.

[0005] The beneficial effects of the above structure are: the movable clamp is movably connected to the base through a fixed shaft, can be easily opened and closed, and is convenient for clamping and releasing the terminal to be tested. The terminal fixing groove opened on the terminal fixing block can accurately fix the terminal to be tested, ensuring that the terminal will not loosen or shift during the test, thereby improving the accuracy and reliability of the test. The locking rod assembly is connected to the base through the locking shaft and can extend out of the space between the terminal fixing block and the movable clamp. Its length exceeds the boundary of the movable clamp and is located on the outside of the movable clamp, so that the locking rod assembly can firmly lock the movable clamp to prevent the movable clamp from accidentally opening during the test. The clamp is reasonably designed and compact in structure, so it can be suitable for testing terminals of various thicknesses.

[0006] The present invention further provides a configuration in which the movable clamp is provided with a clamping block for pressing down and tightening the terminal at the position corresponding to the terminal fixing slot provided in the terminal fixing block. The design of the clamping block enables the movable clamp to fit more closely to the terminal fixing block when closed, and the downward pressure firmly fixes the terminal to be tested in the terminal fixing slot, effectively preventing the terminal from loosening or shifting due to vibration or external force during the test process, thereby improving the accuracy and stability of the test.

[0007] The present invention further provides a locking rod assembly comprising a locking rod and a roller plugged into the locking rod. The movable clamp has arcuate surfaces on both sides of its notch, allowing the roller to smoothly transition along the arcuate surfaces during locking and unlocking. The roller's smooth transition along the arcuate surfaces of the movable clamp's notch makes the locking and unlocking process smoother, reducing friction and resistance. The arcuate transition clamping method also allows for applications with terminals of varying thicknesses.

[0008] The present invention further provides a fixed connection block that is plugged into one side of the base. The fixed connection block has a vertical fixing hole formed in it for securing the base to the test machine. By securing the base to the test machine via the fixed connection block, the terminal test chuck can be kept in a stable position during testing, which helps to reduce test errors caused by chuck shaking or displacement, and improve test accuracy and reliability.

[0009] This utility further configures the terminal to be a fisheye terminal, which can be plugged into a PCB board, and uses the test machine to test the insertion and extraction force of the fisheye terminal. By specifying the test object as the fisheye terminal and considering its plug-in relationship with the PCB board, the test machine can more accurately simulate the insertion and extraction actions in an actual working environment, helping to evaluate the performance of the fisheye terminal in actual applications.
