Problems solved by technology
After the distribution box frame is composed of welding, if you want to move the distribution box, you can only move the distribution box as a whole; and the welding points are easy to be corroded, and the structural rigidity is difficult to guarantee. Once the welding points crack, the power distribution The overall structure of the box will also be destroyed

The invention provides a corner connecting piece which comprises a fixing body and a connecting rod. The fixing body is provided with a plurality of first connecting faces, one end of the connecting rod is connected with the first connecting faces, and the other end of the connecting rod extends in the direction away from the first connecting faces. The connecting rod is used for being connected with an object to be connected, and the corner connecting piece is connected with the object to be connected through the connecting rods, so that a welding mode is avoided. The corner connecting piecesare detached, parts of a whole frame can be detached and moved, so that the problem of structural rigidity caused by the fact that welding points are prone to corrosion is solved. The invention further provides a connecting structure, the connecting structure comprises a connecting pipe and the above corner connecting piece, and the connecting pipe is provided with a connecting channel. The connecting rod can be matched with the connecting channel and can be inserted into the connecting channel, so that the corner connecting piece and the connecting pipe are mechanically fixed. The inventionprovides a power distribution cabinet, so that the electronic devices in the power distribution cabinet are convenient to bear.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a corner connector, a connection structure and a power distribution cabinet. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. [0003] The frame of the distribution box is usually composed of metal rods c...
