[0021] Protective wings 3 are symmetrically arranged on the electric energy meter connector base 1 on both sides of the upper cover base 2, and fixed wings 4 are arranged between the protective wings 3 corresponding to the upper cover base 2 and the electric energy meter connector base 1, and the cross-section of the fixed wings 4 is rectangular, and a connector upper cover 5 is limitedly inserted between the electric energy meter connector base 1, the fixed wings 4, the protective wings 3 and the upper cover base 2. When working, the connector upper cover 5 is inserted from top to bottom between the empty groove formed by the electric energy meter connector base 1, the fixed wings 4, the protective wings 3 and the upper cover base 2, and the electric energy meter connector base 1, the fixed wings 4, the protective wings 3 and the upper cover base 2 cooperate with each other to realize the limitation of the connector upper cover 5 in the front, rear, left, right and lower end direction, thereby preventing the connector upper cover 5 from accidentally slipping out.

[0022] Auxiliary locking protrusions 6 are respectively provided at both ends of the front side of the connector cover 5. The cross section of the auxiliary locking protrusion 6 is arched. The purpose of such arrangement is: the auxiliary locking protrusion 6 with an arched cross section can effectively reduce the friction between the auxiliary locking protrusion 6 and the locking opening 7, reduce the gap worn out of the locking opening 7, and extend its service life.

[0023] A locking opening 7 is provided at a position corresponding to the fixed wing 4 and the auxiliary locking protrusion 6. The cross-section of the locking opening 7 is rectangular. The locking opening 7 is engaged with the auxiliary locking protrusion 6. During operation, when the connector cover 5 is inserted between the empty groove formed by the electric energy meter connector base 1, the fixed wing 4, the protective wing 3 and the upper cover base 2, the locking opening 7 is engaged with the auxiliary locking protrusion 6, which further fixes the connector cover 5 and can effectively prevent the connector cover 5 from falling off from its upper end.

[0024] An assembly groove 8 is provided at the center position of the front face of the connector upper cover 5, and an upper cover protective cover 9 is detachably installed in the assembly groove 8.
