AI Technical Summary
Technical Problem
Existing pulse test fixtures are cumbersome to operate when fixing resistors, and twisted power cords can cause resistor deformation or breakage, affecting test accuracy.
Method used
Design a pulse test fixture including a base and an adjustable clamp. Through the sliding cooperation between the guide part and the guide mating part, the position of the clamp can be adjusted and limited, ensuring that the resistor remains horizontal and coaxial during the test and reducing the influence of the torsional force when the power line is connected on the resistor.
Benefits of technology
It improves testing accuracy and reliability, avoids deformation or breakage of small-sized resistors, and enhances the accuracy of assessing the instantaneous overload capacity of resistors.

Abstract
The utility model discloses a kind of pulse test fixtures, including base and two clamps, base is provided with the guiding portion extending along first direction, each clamp is fixed resistance one end with clamping position, and is slidably matched with guiding portion through guiding cooperation portion, can be adjusted position along first direction.In the utility model, through the adjustable spacing design of clamp, the versatility of fixture is improved, and the operation mode of sliding adjustment clamp position is simple and fast.Moreover, by the limiting of guiding portion to two clamps, it can be ensured that two clamping positions maintain horizontal coaxial state during resistance testing process, effectively reduce the torque influence of torsional force on resistance when power cord is connected, avoid the deformation or fracture phenomenon of small size, thin thickness resistance, thereby improve the precision and reliability of pulse test, make the evaluation of resistance instantaneous overload capacity more accurate.
