Detailed ways

The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

Example 1

A new type of current transformer secondary circuit short wiring, as shown in Figure 1, includes a bus head, several wires and several connectors; one end of all the wires is fixedly connected to the bus head, and the other end of each wire Connect a connector.

As shown in Figure 2, the connector includes a pole, a gasket and a screw; wherein the pole is connected to the wire, the screw and the gasket are fixed in the pole, and the gasket is on the upper part of the screw and fixes the screw. The connector can be fixedly connected with the current terminal and cannot be loosened. The connecting wire can be connected to four current terminals and can pass a current of more than 10A. The bus head connects the four wires.

Preferably, the upper part of the rod is a threaded structure for threaded connection with the screw rod.

Preferably, both the surface of the connector and the wire are covered with insulating material.

Preferably, the insulating material is insulating plastic.

Preferably, the number of wires is four.

Preferably, the number of said connectors is 4.

The short wiring of the secondary circuit of the current transformer developed by the utility model is connected with the pole column and the wire, and the connecting screw rod and the gasket are fixed in the pole column to avoid the problem of false touch caused by the screw falling and the screw rod shaking. Integrated structure, the screw rod can be rotated and screwed with the current terminal. At the same time, the size of the rod column is suitable for the access and contact of the current terminal, which ensures the contact quality. The screw rod can be rotated, and the sheath can be held by hand during operation, which can be tightened by hand, and then tightened by a screwdriver, which is easy to operate.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. All modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the claims of the present invention.
