Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of bending equipment, especially relates to a terminal bending test fixture. BACKGROUND
[0002] In the electrical and electronic manufacturing industry, the bending test of the terminal is an important link to ensure the quality and reliability of the connector. As an important part of the connector, the bending performance of the terminal directly affects the service life and performance stability of the connector. Therefore, accurate bending test is carried out on the terminal to evaluate its strength and durability under different bending conditions, which is crucial to ensure product quality.
[0003] However, the existing terminal bending test method has the problems of simple test fixture design, inability to accurately control the bending angle and force, leading to inaccurate test results, in addition, some test fixtures lack the necessary positioning and guiding functions, so that the terminal is easy to deviate or be damaged during the test process, which not only affects the accuracy of the test, but also may cause unnecessary damage to the terminal, increasing the production cost and test time. SUMMARY
[0004] Therefore, the utility model aims at providing a terminal bending test fixture which is stable in structure, easy to operate, can accurately control the bending angle and meet the diversified test requirements.
[0005] In order to achieve the above purpose, the utility model adopts a terminal bending test fixture, which comprises a base and a limiting block inserted into the base, limiting grooves for movably connecting swing arms and guide grooves for inserting terminals are formed at both ends of the limiting block, the swing arms are movably connected with the limiting block through the limiting grooves, and a positioning guide block is clamped on one side of the guide groove, a clamping groove for clamping one end of the terminal is formed in the positioning guide block, the terminal is inserted into the guide groove of the limiting block, one end of the terminal is clamped on the positioning guide block through the clamping groove, and the other end of the terminal abuts against the base for bending test.
[0006] The above structure has the beneficial effects that the base, the limiting block, the swing arm and the positioning guide block are connected closely, ensuring the overall stability of the fixture, the design of the guide groove and the positioning guide block enables the terminal to maintain a stable posture during bending, ensuring the accuracy of the bending angle, and the swing angle of the swing arm can be adjusted to meet the requirements of different bending angles and satisfy the diversified test requirements.
[0007] The utility model further sets up the stopper block in the both sides of swing arm all is provided with the clamping block, is used for fixing the position of swing arm. The design of clamping block makes swing arm can be fixed firmly when swing to specific position, prevents swing arm accidental movement or shaking in the test process, thereby strengthens the stability of swing arm.
[0008] The utility model further sets up the opening angle of stopper groove is forty degrees, is used for preventing the bending angle is too big. Through setting the opening angle of stopper groove is forty degrees, can accurate control terminal in the maximum angle of bending process, thereby avoided the terminal damage or performance decline because bending angle is too big.
[0009] The utility model further sets up swing arm is left and right swing. Through the bending test of left and right swing swing arm, can ensure the stress direction and angle of terminal are consistent every time, this helps to improve the accuracy and reliability of test.
