When the threaded barrel 4 rotates to drive the plate Ⅰ51 to move toward the direction of the movable plate 74, under the elastic force of the spring Ⅰ79, the two movable plates 74 move toward each other and seal the groove of the electric meter 1.

A method for using a wiring terminal for installing an online diagnostic device for an electric meter, the method comprising the following steps:

Step 1: Pass the wire through the through hole Ⅰ56, through hole Ⅱ63 and finally into the insertion hole 22;

Step 2: Rotate the threaded barrel 4 to move the plate I 51 and the plate II 61 toward each other, and clamp the wire by the push plate 55;

Step 3: While rotating the threaded barrel 4, the two movable plates 74 move toward each other and clamp the wires through the circular grooves 75. At the same time, the grooves of the electric meter 1 are sealed by the two movable plates 74 to reduce the entry of dust and moisture.

The working principle of the present invention is as follows: when using the device, a plurality of wires are respectively passed through the corresponding through-holes Ⅰ56 and Ⅱ63 and finally placed in the insertion hole 22, and then the threaded cylinder 4 is rotated. The outer circumferential surface of the threaded cylinder 4 is provided with a reverse thread. Therefore, during the rotation of the threaded cylinder 4, the plate Ⅰ51 and the plate Ⅱ61 move toward each other in the state shown in FIG. 1. During the movement of the two toward each other, the plate Ⅱ61 drives the slide plate 641 to move, and then drives the insertion rod 643 to move, so that the insertion rod 643 contacts the inclined surface on the push plate 55, and then drives the two sides of the through-hole Ⅰ56 through the inclined surface. The two push plates 55 move toward each other until the two push plates 55 clamp the wire in the through hole Ⅰ56, and at the same time, the insertion rod 643 is inserted into the socket 21. In the process of the plate Ⅰ51 moving with the rotation of the threaded barrel 4, the plate Ⅰ51 drives the fixing device 8 to approach the movable plate 74. Since the triangular block 82 on the fixing device 8 moves away from the movable plate 74, the two movable plates 74 move toward each other close to the inclined surface of the triangular block 82 under the pulling force of the spring Ⅰ79, and seal the groove at the lower end of the electric meter 1 to prevent dust and moisture from entering and affecting the service life;

When the electric meter is maintained and other wires need to be removed or reinstalled, the transmission block 76 at the corresponding position of the wire that does not need to be removed is rotated, so that the transmission block 76 drives the sliding block 712 on its side to rotate and disengage from the arc groove 711, and then the transmission block 76 is pushed in the direction of the slide plate 641. The transmission block 76 moves in the vertical hole 715 and drives the sliding block 712 to embed into another arc groove 711. The transmission block 76 also drives the transmission rod 77 to move in the groove 642 and finally rests on the inner top wall of the groove 642. Therefore, when the threaded barrel 4 is rotated in the opposite direction, the plate I51 and the plate II61 move in the opposite directions. Since the slide plate 641 is supported by the transmission rod 77, the slide plate 641 does not move with the plate II61, and the insertion rod 643 limits the push plate 55 to move to the original position, so that the push plate 55 always clamps the corresponding wire, thereby preventing all the wires on the terminal block 2 from falling off when installing or removing other wires, affecting the work efficiency.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
