The existing current transformer is usually cast by inserting the wire outlet terminal of the coil into the wire connection hole on the wire connection cover, bonding the wire connection cover on the transformer shell, and then injecting high-temperature liquid into the transformer shell. The casting liquid can cause great impact to the metal wire in the flowing process to deform the wire, and meanwhile, the high-temperature casting liquid can also reduce the bonding strength of the wiring cover, so that the wiring cover can be loosened. Therefore, the fixing of the terminal cover by the jacking action and the bonding manner of the wire outlet terminal is unreliable.

The positioning cambered surface attached to the inner hole surface of the middle threading hole positions the positioning table in the radial direction, the positioning flange positions the positioning table in the axial direction, and the stop end surface of the circumferential stop of the inner ring boss positions the positioning table in the circumferential direction, so that the positioning table is matched with the annular shell in a positioning way, the positioning table is relatively fixed with the second positioning part, and meanwhile, the second positioning part is fixedly connected with the wiring cover, so that the relative fixation of the wiring cover and the annular shell is realized, the fixation is firm, and the phenomenon of loosening or shifting of the wiring cover cannot occur.
The whole T-shaped structure that has horizontal limit and vertical limit of locating platform, the cambered surface that fixes a position sets up in the both ends position of horizontal limit, and three-point location is more reliable.
The positioning flanges are arranged at two ends of the horizontal edge.
The width of the positioning flange is consistent with the thickness of the inner annular wall of the annular shell, so that the positioning flange does not protrude out of the inner annular wall of the annular shell in the radial direction, and the casting of the coil in the transformer shell is not affected.
The vertical side end part of the positioning table is also provided with a lap joint flange lapped on the horizontal section of the inner hole surface of the threading hole, and the lap joint flange is matched with the positioning flange to position the positioning table in the axial direction more reliably.
The first positioning component and the second positioning component are detachably connected, so that the first positioning component and the second positioning component are convenient to detach.
The positioning connection structure arranged on the second positioning component is a connection hole corresponding to the wiring hole on the wiring cover, and the structure is simple.
