Each male conductor terminal 6 is respectively disposed through the inner cavity of the adjacent through slot 8. There are two metal guide posts 5. The plug plastic body 3 is provided with a fixing cylinder 4 that is compatible with the metal guide posts 5. The metal guide posts 5 and the fixing cylinder 4 are made by embedded injection molding. The socket 2 includes a socket plastic body 11, a conductor female terminal 15, and a metal guide sleeve 13; The number of female conductor terminals 15 and male conductor terminals 6 are matched, and the socket plastic body 11 is provided with grooves 18 for fixing female conductor terminals 15, and each female conductor terminal 15 is inserted into the inner cavity of the adjacent groove 18.

The metal guide sleeves 13 and positioning grooves 12 are made by embedded injection molding.

[0023] Two first anti-return grooves 23 are symmetrically formed on the male conductor terminal 6. Two first anti-return spring arms 22 are inserted into the inner cavity of the first anti-return groove 23. Each first anti-return spring arm 22 is elastically connected to the inner wall of the through groove 8. When the male conductor terminal 6 is inserted into the inner cavity of the through groove 8, the first anti-return spring arm 22 can be inserted into the inner cavity of the first anti-return groove 23 to form a reverse buckle, thereby preventing the male conductor terminal 6 from being removed from the plug plastic body 3.

When the metal guide post 5 is embedded into the inner cavity of the fixed cylinder 4, plastic is injected into the first annular anti-reverse groove 10 to limit its axial movement. And when the metal guide sleeve 13 is embedded into the inner cavity of the positioning groove 12, plastic is injected into the second annular anti-reverse groove 14 to limit its axial movement.

[0029] The edge of the metal guide sleeve 13 is rounded, and the head of the metal guide post 5 is sloped. When the male and female connectors are mating, the metal guide sleeve 13 and the metal guide post 5 contact each other first. Even if there is a proper deviation in the theoretical relative position of the male and female connectors, they can still be effectively guided and completed for mating.

The first fixing hole 9 and the second fixing hole 21 are provided on the male conductor terminal 6 and the female conductor terminal 15 respectively, which can be used to fix other conductors and connect them to achieve power transmission. When the male and female connectors are mated, the metal guide sleeve 13 contacts the metal guide post 5 first. Even if there is a proper deviation in the theoretical relative position of the male and female connectors, they can still be effectively guided and completed. In addition, by designing female bullet arms 16 with a certain distance between the front and rear on the female conductor terminal 15, and the number of female bullet arms 16 on the front and rear sides is the same, the insertion and extraction force of the connector when mating with the copper busbar can be reduced, which is beneficial to actual operation and makes the contact of the connector safer and more reliable.
