Outer lead wire device for fixedly assembling electric power instrument box

Abstract

The invention discloses an outer lead wire device for fixedly assembling an electric power instrument box. The structure of the device comprises a front view surface and an electric power instrument box. The front view surface is connected with the electric power instrument box; an outer lead and an inner lead are connected together through an outer lead terminal pair; the outer lead is arranged in an arc interlayer; a pocket shell is forced to be stressed to be propped against a propping and buckling corner in the electric power instrument box to bear an external propping force; an internal solid angle plays a role in limiting the range, and can perform extrusion to expand a stress surface when the external connection wire and the internal connection wire are connected and dragged by gravity, so when the resistance is lost, the lead can be reset in time; therefore, the outer lead terminal generates a pressing force in the bending process, and the arc interlayer can be pressed and bent; a joint ball can evenly distribute the force, so an abutting joint portion is protected; when the outer layer loses resistance, the outer layer returns in time, and when the joint opening is stressed by the vertical plane, the joint opening can be in a buffering bent shape, so the joint opening is protected to the maximum degree and bent together.

Description

technical field [0001] The invention belongs to the field of electric power, and more specifically relates to an external lead wire device for fixing and assembling an electric meter box. Background technique [0002] When the power meter box is installed and fixed on a vertical plane, the rear end will extend out of the external lead wire port, so that the external lead wire and the internal wire can be connected smoothly, and its power can be controlled and monitored. [0003] Based on the above-mentioned inventor's discovery, the existing electrical meter box external lead wiring device mainly has the following deficiencies, such as: [0004] 1. When the external lead wire and the connecting port are stuck together, it will be pressed on the connecting port due to the drooping gravity of the wire, so that the connecting port is more likely to loosen after being pressed for a long time, and even have poor contact with the inner line. [0005] 2. When the external wires ar...

Problems solved by technology

[0007] In order to solve the above-mentioned technology, when the external lead wire and the connecting port are stuck together, it will be pressed on the connecting port due to the drooping gravity of the wire, so that the connecting port is easy to loose after being pressed for a long time, and even has poor contact with the internal wire. When the external lead wire is placed When the rear end collides with a vertical plane, the sagging angle of the wiring will have a certain arc, and it will produce rigid pressure when it is collided with the plane, and it is easier to crush it to death or even break the shell.
