Description

Technical Field

[0001] The utility model relates to the technical field of mutual inductors, in particular to a mutual inductor wiring structure. Background Art

[0002] A low-voltage current transformer is a device that can convert high alternating current into easily controllable low current. It has the characteristics of excellent performance and stable accuracy. The low-voltage current transformer includes a low-voltage current transformer body and two terminals connected to the low-voltage current transformer body. When wiring each terminal, one end of the wire is wrapped around the terminal, and the nut on the terminal is rotated to tighten the terminal end of the wire to the terminal. This method requires the staff to tighten the nuts one by one when wiring the transformer, which is time-consuming, thereby delaying the transformer wiring time and extending the working time. It has certain limitations when used.

[0003] After searching the existing public patent number: CN202322059391.1, the public patent name is: a transformer wiring structure, including a transformer body, a pressing plate is arranged above the transformer body, the surface and back of the transformer body are fixedly connected with mounting blocks, the top of the transformer body is fixedly connected with a connecting pipe, the interior of the connecting pipe is penetrated by a pulling rod, the top of the extrusion block is fixedly connected with a first compression spring, the interior of the connecting pipe is provided with a positioning hole, and the bottom end of the pulling rod is penetrated by the interior of the positioning hole. The utility model uses a connecting pipe, a pulling rod, an extrusion block, a first compression spring, a positioning hole, a pressing plate and a handle in combination, so that the connecting wire of the transformer body can be quickly connected, and at the same time avoids the situation that the bolt fixation is more time-consuming, and when the connecting wire is connected to the transformer body, only the pressing plate needs to be pulled upward to connect the three connecting wires at the same time, which is highly efficient and can speed up the progress of the transformer body wiring work to a certain extent.

[0004] However, when the above device is in use, when the pressing plate is pulled to connect the three connecting wires, there is a risk that the connecting wires first inserted into the positioning holes will fall off; and pulling three sets of springs at a time is relatively laborious, so there is room for improvement.
