The insulative mounting socket 1 may be made of plastic so as to prevent current from being transmitted to the outside. The insulating mounting base 1 is provided with a measuring port 4 and at least two connecting grooves 5. For example, the measurement port 4 is located on the upper surface of the insulative mounting base 1; the number of the connecting grooves 5 is two, and the two connecting grooves 5 are symmetrically arranged on two opposite side surfaces of the insulating mounting seat 1; the number of the connecting grooves 5 is three, two of the connecting grooves 5 are symmetrically arranged on two opposite side surfaces of the insulating mounting base 1, and the other connecting groove 5 is arranged on the lower surface of the insulating mounting base 1, so that the three connecting grooves 5 are distributed in a triangular shape.
The first conductive member 2 and at least two second conductive members 3 are located in the insulative mounting base 1. The first conductive member 2 and the second conductive member 3 are made of conductive metal, such as copper foil. One end of the first conductive member 2 is located at the measurement port 4 or protrudes out of the measurement port 4. The other end of the first conductor 2 is connected to one end of at least two second conductors 3. The other end of each second conductive member 3 is inserted into each connecting groove 5. Each connecting slot 5 is for insertion of an external conductor 6. It should be understood that the first conductive member 2 and the second conductive member 3 may be bent accordingly as necessary for convenient wiring in the insulative mounting socket 1. The second conductive member 3 is adapted to contact an external wire 6 inserted into a connection groove 5 where the other end of the second conductive member 3 is located. The first conductive member 2 is used to connect and cooperate with a measuring device (often a multimeter or a clamp ammeter) to measure parameters such as current or voltage on the first conductive member 2, and then obtain parameters such as current or voltage in the external lead 6. It should be understood that the first conductive member 2 and the second conductive member 3 may be a unitary structure, i.e. one end of all the second conductive members 3 is screwed together, or welded together, etc., to facilitate the wiring of the measuring device.

Therefore, when the external lead 6 is inserted into the connecting groove 5, the insulation limit part at the connecting groove 5 abuts against the side wall of the external lead 6, so that the external lead 6 is clamped by the insulation limit part and the inner surface of one side wall of the connecting groove 5, thereby avoiding the external lead 6 from slipping off from the connecting groove 5, and further fixing the external lead 6 is firmer. When the external conductor 6 needs to be taken out from the connecting groove 5, the insulation limiting member can be moved, so that the insulation limiting member no longer abuts against the external conductor 6, and the external conductor 6 can be pulled out. The insulating locating part can adopt the plastics material to avoid electrically conducting, guarantee safety.

One side wall of each first limiting block 7, which faces to the sliding opening 9 of the sliding groove 8 where the first limiting block is located, is connected with one end of each driving piece 10. The other end of each driving member 10 extends out of the corresponding sliding opening 9 and is movable in the corresponding sliding opening 9. Therefore, the driving member 10 can be shifted by the driving member 10, so that the driving member 10 drives the first limiting block 7 to move, and one end of the first limiting block 7 moves into the connecting groove 5 or one end of the first limiting block 7 retracts into the sliding groove 8 from the connecting groove 5, so that the first limiting block 7 is convenient to clamp the external lead 6 or the first limiting block 7 is not abutted to the external lead 6 when the external lead 6 is inserted, and the external lead 6 is convenient to be pulled out.

The flexible cord 13 may be an insulating material to avoid electrical shock. The flexible rope 13 is arranged to facilitate the insertion and extraction of the second limiting block 12, and the second limiting block 12 can be prevented from being lost.
The size of one end of the second stopper 12 is smaller than the size of the other end of the second stopper 12, for example, the second stopper 12 is in a truncated cone shape, so that the second stopper 12 can be inserted and pulled conveniently. The size of the other end of the second stopper 12 matches the opening of the connecting groove 5, so that the external wire 6 is more stably held.
