The invention discloses a conductive clamp for a plug lead bending test. The conductive clamp comprises a box-shaped shell, wherein the top of the shell is provided with a pressing bolt; the end of the pressing bolt is pressed against the top surface of a U-shaped pressing block; the open end of the U-shaped pressing block is downward, and a left clamping block and a right clamping block are arranged below the U-shaped pressing block; the side faces of the left clamping block and a right clamping block are provided with a first inclined surface and a second inclined surface; the first inclined surface is pressed against the edge of the open end of the U-shaped pressing block; the second inclined surface is pressed against one side faces of a left pin and a right pin; a compressed spring is arranged between the left clamping block and the right clamping block; a clamping groove is formed between the left clamping block and the right clamping block; an upper pin is arranged in the clamping groove; a left inclined cushion block and a right inclined cushion block which are symmetrical to each other are arranged in the shell; conducting strips are respectively arranged on inclined surfaces of the inclined cushion blocks; and the conducting strips are pressed against the other side face of the left and right pins. According to the conductive clamp, the plug can be clamped, electric connection is formed between the plug and the pin, and the installation is convenient; the electrical connection performance is safe and reliable, and the insulating performance is high.
Description
technical field [0001] The invention relates to the field of testing devices for electrical components, in particular to the field of plug lead bending testing devices. Background technique [0002] Before the plug leaves the factory, it is necessary to sample the bending performance of the lead wire of the plug. Specifically, the plug is clamped on the test bench, and the power cord of the plug is bent in different directions. Whether bending the lead wire of the plug within the range will affect the safe use of the plug. [0003] At present, the fixture for the plug lead bending test only has the function of clamping the plug, and it is necessary to connect additional wires during the power-on test, which is cumbersome to operate; the connected wires are generally wound on the pins, and the electrical connection is not reliable and has certain dangerous. Contents of the invention [0004] Based on the problems of single function, cumbersome operation, poor safety and u...
