Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1 to 5, the socket of the large-current single-core power connector comprises an insulating device, a conducting device, a fixing device, a safety protection device and a phase sequence identification device. The insulation device comprises an insulation shell 1, wherein guide and anti-falling grooves 101 are formed in two sides of the outer surface of the insulation shell 1 and play a role in guiding when being matched with a plug; after the connector is inserted in place, the connector and the plug are locked and prevented from falling off, and a first locking function is realized; the locating pin 4 is fixed on the plug pin 3, and after the connector is inserted and combined with the plug and rotates in place, the locating pin 4 is clamped in the plug shell to realize a second locking function. The conducting device comprises a plug pin 3, a contact busbar 5 and a plane contact spring 8. The plug pin 3 and the contact bus bar 5 adopt a split structure, and the two parts are respectively machined, so that raw materials are saved, the machining difficulty is reduced, and the production cost is reduced; the side face and the bottom face of the bottom end of the bolt 3 are connected with the top face of the contact busbar 5 through the high-frequency induction heating welding mode, and the problems that threaded connection is poor in fixation and the connection part generates heat and exceeds the standard when the power is on are solved. The bottom surface of the contact busbar 5 is provided with two dovetail grooves, the planar contact spring 8 is inserted into the dovetail groove 502, after the planar contact spring is installed in place, the symmetrical 8 positions are fixed at the stamping point 501 in a riveting mode, the structure improves the connection mode of the core piece and the power equipment, rigid connection is changed into elastic contact, the contact area is increased, and the heavy current bearing capacity is increased.
