Because natural radian is generated in the manufacturing process of the steel-cored aluminum stranded wire, before the wire clamp is crimped, the angle of the wire clamp and the radian of the steel-cored aluminum stranded wire are required to be properly matched, if the angle is matched with the radian of the steel-cored aluminum stranded wire in error, the crimped wire clamp is required to be broken, and a new wire clamp is crimped again, so that unnecessary waste is caused.
The jointing clamp is difficult to disassemble. The fastening bolt applied to the outdoor jointing clamp is influenced by natural factors for a long time, oxidation of the bolt cannot be avoided, the difficulty of disassembling the oxidized bolt is high, and the fastening bolt is the biggest pain point for guaranteeing the effective time of operation.
4. And equipotential operation risks are brought in the disassembly and assembly processes of the wire clamps, and the risk operation level is improved. In order to ensure the power supply reliability, the overhaul equipotential operation load is gradually increased, the wire diameter of the current steel-cored aluminum strand is generally 400 square millimeters, 500 square millimeters or more, 4 or 6 connecting bolts of the wire clamp exist, because the disassembly and assembly of a plurality of bolts are sequential, if the contact surface of the bus-bar end wire clamp deviates from the contact surface of the drainage-wire end wire clamp, the disassembly and assembly process is difficult, and extremely high risks are brought to equipotential operators.

Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings.
Examples
Referring to fig. 1, the cone plug-in type power wiring terminal comprises two connecting terminals and a fastening bolt. The first terminal 10 includes a conical cavity tube 11 and a first wire connection tube 12, the inner wall of the conical cavity tube 11 is used for contacting with the second terminal, the conical cavity tube 11 and the first wire connection tube 12 are connected by welding, crimping or an integrated forming mode, and the first wire connection tube 12 is used for connecting a first wire. The second terminal 20 comprises a cone 21 and a second wire connecting tube 22, the cone angle of the cone 21 is equal to the cone angle of the cavity of the conical cavity tube 11, the cone 21 is used for being inserted into the conical cavity tube 11, the surface of the cone 21 is attached to the inner wall of the conical cavity tube 11 to realize annular full-contact connection of the cone 21 inserted into the conical cavity tube 11, the cone 21 is connected with the second wire connecting tube 22 in a welding, crimping or integrated forming mode, and the second wire connecting tube 22 is used for being connected with a second wire.
