Stress-resisting test device of extension socket

Abstract

The invention discloses a stress-resisting test device of an extension socket. The stress-resisting test device comprises a base, a motor, a dynamometer and a fixed seat; the base comprises a carrying surface; the motor is connected to the carrying surface, the motor comprises a motor shaft, and the center axis of the motor shaft is perpendicular to the carrying surface; a storage seat is arranged on the carrying surface, the storage seat is provided with a slide groove, one end of the slide groove forms a closed end, and the closed end of the slide groove is adjacent to the motor; one end of the dynamometer is connected to a motor shaft by virtue of a connecting rope and arranged between the storage seat and the motor, and the other end of the dynamometer is provided with a plug. According to the stress-resisting test device of the extension socket, a tested extension socket is arranged in the slide groove, so that the connecting rope and the plug are respectively connected to two opposite ends of the dynamometer; since the connecting rope and the plug are respectively connected to the motor and the tested extension socket, under the rotation of the motor, the connecting rope and the plug can produce pull forces in opposite directions for the dynamometer so as to apply stress onto the tested extension socket, the stress-resisting test can be carried out, and the reliability of the tested extension socket in actual use can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a stress-resistant testing device for plug-in strips. Background technique [0002] The socket is formed by putting multiple sockets together. The socket can not only be used for multiple purposes, but also save space and lines. It is a necessity of life. The use method of the plug-in strip is to insert and pull out the plug, and ensure good contact between the plug electrode and the plug-in strip electrode to realize the connection of the circuit. In the actual use process, when plugging and unplugging the plug, the plug is often pulled by human beings, which will cause the physical damage of the plug strip to be damaged or cracked, which reduces the service life of the plug strip, which is closely related to the stress resistance of the plug strip. Therefore, the durability of the socket must be considered at the beginning of the design. In the prior art, there...
