Connect electric connector component fast

Technical Field

The utility model relates to an electric power construction accessory technical field specifically is a connect electric connector subassembly fast.

Background

With the continuous and deep promotion of the transformation work of the distribution internet of things, massive terminal intelligent sensing equipment needs to be deployed at key nodes such as distribution transformers in transformer areas, line branches and terminal household photovoltaic nodes, and basic data such as the running state, the equipment state, the environmental state and other auxiliary information of a low-voltage distribution network are collected. Due to the fact that most reconstruction implementation nodes are long in age, old in facilities and complex in environment, the expansibility requirement of upgrading and reconstructing is not considered, and particularly, massive sensing equipment is connected, and a working power supply cannot be safely and efficiently provided for the connected equipment. Therefore, great challenges are brought to site construction, debugging, operation and maintenance. Meanwhile, with the continuous development of the economy of China and the continuous improvement of the living standard of the people, the dependence of the society on electric power is increased year by year, and the sustainable development of the economy of China is more and more independent of the continuous supply of the electric power. In order to fundamentally and effectively reduce economic loss caused by power failure overhaul and maintenance work, the uninterrupted operation is widely applied to engineering construction and transformation of the low-voltage distribution network.

1. the power taking device adopts a magnetic attraction and metal nut combination mode, is only suitable for the situation that the tail part of an electrified bolt faces outwards, and ensures that the power taking device and the electrified nut are reliably fixed due to the fact that a tail part thread needs to stretch out for a certain length, and has great limitation. The magnetic iron is adsorbed by the magnet and the nut to restrain the degree of freedom along the axial direction of the bolt, and the degree of freedom along the axial direction of the bolt and the degree of freedom along the radial direction of the bolt are restrained by screwing the exposed screw threads of the metal nut and the bolt. However, the field environment for transforming the power distribution network is uncertain, if the head of the electrified bolt faces outwards or the exposed screw teeth at the tail part are too short, the mode cannot restrict the degree of freedom along the radial direction of the bolt, so that the fixation is unreliable, and the electrified bolt is easily pulled off in the wiring process or is accidentally knocked off by constructors. Once the electricity taking device is knocked off, the magnet can be adsorbed on any ferromagnetic material at once, particularly falls into a narrow gap, so that the electricity taking device cannot be taken out well, and a constructor possibly needs to pass through a live conductor by hands in the taking-back process, so that serious potential safety hazards exist;

2. the current-carrying conductor of the power taking part of the power taking device is a metal nut, the contact surface with the electrified bolt is mainly the end surface of the metal nut, and the end surface of the magnet are positioned on the same plane. However, in the actual manufacturing process of a product, the end face of the metal nut and the end face of the magnet cannot be completely coplanar, and the end face of the metal nut is lower than the end face of the magnet due to the accumulation of the manufacturing tolerance and the assembly tolerance of parts, so that the contact resistance between the metal nut and the electrified bolt is increased, the metal nut is heated after long-time electrification, the temperature rise of the device is increased, the local temperature is too high, the aging of an insulating shell is accelerated, and the insulation hidden danger is formed;

3. the magnet of the electricity taking device is sleeved on the outer ring of the metal nut and forms a closed ferromagnetic loop along the circumferential direction. When the metal nut is electrified with alternating current, an alternating magnetic field can be generated on the magnet, and then eddy current is generated in the magnet, so that the magnet generates heat, the temperature rise and the local temperature of the device are increased, the aging of the insulating shell is accelerated, and the insulating hidden trouble is formed.
