Waterproof and anti-loosening junction box

Abstract

The invention relates to a waterproof and anti-loosening junction box. The waterproof and anti-loosening junction box comprises a junction box, a cover shell and a wiring structure; a first wiring groove is formed in the bottom of the junction box; a second wiring groove is formed in the cover shell; the wiring structure is a socket type integrated wiring block, and a wiring socket integrated in the wiring structure faces to the first wiring groove; the wiring socket comprises a socket main body provided with a guiding conical surface and screw thread sleeves, and a rotary pressing structure provided with screwing screw threads and a conical surface; and one end of the rotary pressing structure is a screwing end while the other end is a pressing conical surface with pressing sharp teeth. The waterproof and anti-loosening junction box has the advantages of corrosion resistance, aging resistance, anti-loosening property of wiring terminals, capability of preventing electricity stealing, high reliability and the like.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a waterproof and detachment-proof junction box. Background technique [0002] The junction box is a common component in electrical standard wiring, which is used for wiring and safety protection. Generally, its conductors and wiring screws are made of H62 copper, and the surface is nickel-plated. However, due to the poor self-locking ability of this structure, And there is no anti-off function, and it is easy to fall off due to loose wiring. Moreover, its circuit connection is not reliable enough, it is easy to fail, and it cannot be detected independently after the occurrence of man-made electricity theft, which may easily cause disputes over electricity charges; the insulation box material is generally polycarbonate, which has poor corrosion resistance, aging resistance and electrical insulation properties. It is not suitable for outdoor wiring, which brings a lot of troub...

[0002] The junction box is a common component in electrical standard wiring, which is used for wiring and safety protection. Generally, its conductors and wiring screws are made of H62 copper, and the surface is nickel-plated. However, due to the poor self-locking ability of this structure, And there is no anti-off function, it is easy to fall off due to loose wiring

Moreover, its circuit connection is not reliable enough, it is easy to fail, and it cannot be detected independently after the occurrence of man-made electricity theft, which may easily cause disputes over electricity charges; the insulation box material is generally polycarbonate, which has poor corrosion resistance, aging resistance and electrical insulation properties. It is not suitable for outdoor wiring, which brings a lot of trouble to the installation, use, observation and replacement of the junction box, and cannot be used in harsh environments and working conditions

[0003] At the same time, in many places in our country, there are citizens modifying electric meters without permission or using external wiring to steal electricity. The circuit system using conventional wiring cannot respond independently, causing a large number of unknown losses to the State Grid.
