All-in-one test power supply access assembly

Abstract

The invention discloses an all-in-one test power supply access assembly which comprises a four-in-one plug, an output cable and a test box power connection box. The four-in-one plug comprises a C-shaped protective cover and a rectangular shell, the C-shaped protective cover is a notch circular insulating ring, a gear shaft is arranged in the center of the C-shaped protective cover, the gear shaft and the C-shaped protective cover synchronously rotate, and the gear shaft is rotationally connected with the rectangular shell; the rear ends of the four-hole plug assembly, the large three-hole plug assembly, the small three-hole plug assembly and the two-hole plug assembly are all provided with driving and resetting assemblies of the same structure, so that the corresponding plug assemblies can be pushed out in the rotating process of the C-shaped protection cover to be connected with a power supply. By arranging the C-shaped protective cover, the gear shaft and the rack pushing mechanism, the plug assembly automatically protrudes out of the rectangular shell so as to be connected with a power supply; through the arrangement of the compression spring, the unused plug assembly is retreated into the rectangular shell in a natural state, so that the plug assemblies on the other three surfaces are prevented from being accidentally popped out, and the electric shock danger is avoided.

Description

technical field [0001] The invention relates to the field of test box connection boxes, in particular to an all-in-one test power supply connection assembly. Background technique [0002] During the electrical test of power equipment, due to the influence of various environmental factors, the electrical test equipment needs to change the working location frequently, and the power interface forms used by the electrical test equipment are diversified, including air switches, switches, multi-hole sockets, special sockets Therefore, the electrical test equipment is connected between various power interfaces, and the wiring adjustment is cumbersome and labor-intensive. [0003] Experimenters with low sense of responsibility and lack of safety awareness often find themselves in a situation of laziness, convenience, and illegal wiring. They insert the power lead directly into the socket, hang it on the fuse of the switch, and hang it on the wiring lead of the air switch. In the ca...

AI Technical Summary

Problems solved by technology

In the case of a large power load, the socket hole is often burned out and short-circuited, resulting in poor contact of the switch blade fuse, thermal fuse or falling off and short circuit, causing the air switch wiring to be short-circuited and tripped
