[0024] A second conductive plate 50, which is movably disposed in the insulating housing 10 and disposed below the plug socket 40 and the second wiring socket 30. An elastic member 502 is installed between the lower surface of the second conductive plate 50 and the insulating housing 10. The second conductive plate 50 is connected to the plug socket 40 and the second wiring socket 30 under the action of the elastic member 502;

[0025] The extrusion piece 60 is provided with two extrusion pieces 60, and each of the extrusion pieces 60 is provided with relatively arranged protrusions 601, and the protrusions 601 are located in the through hole A101. The upper end of the extrusion piece 60 is fixed to the inner wall of the insulating shell 10, and the lower end is fixed to the upper surface of the second conductive plate 50. When an object is inserted between the extrusion pieces 60, the protrusions 601 are deformed and squeeze the second conductive plate 50 to separate from the plug socket 40 and the second terminal socket 30.

[0026] The first wiring seat 20 is arranged in the first installation groove 102. The first installation groove 102 is located on the side of the insulating housing 10 and is provided with a first wiring groove 201 connected to the first wiring seat 20. The upper end surface of the insulating housing 10 is provided with a through hole B103 connected to the first wiring seat 20. The through hole B103 is provided with a screw A202 for tightening the wiring. The screw A202 is threadedly connected to the first wiring seat 20.

[0027] The second terminal block 30 is arranged in the second installation groove 104. The second installation groove 104 is located on the side of the insulating shell 10 and is provided with a second terminal block 301 connected to the second terminal block 30. A through hole C105 connected to the second terminal block 30 is provided on the upper end surface of the insulating shell 10. A screw B302 for tightening the wiring is provided in the through hole C105. The screw B302 is threadedly connected to the second terminal block 30.

[0028] Specifically, an insulating shell 10 is provided, and a first mounting groove 102 and a second mounting groove 104 are provided in the insulating shell 10 to respectively install the first terminal block 20 and the second terminal block 30, and the first terminal block 20 and the second terminal block 30 can use frame-shaped copper or other metal wire posts, and the first terminal block 20 and the second terminal block 30 are respectively threadedly connected with screws A202 and screws B302 for fixing the wires extending from the first terminal slot 201 and the second terminal slot 301. Under normal circumstances, when in use, the elastic member 502 is arranged below the second conductive plate 50. Under the action of the elastic member 502, the second conductive plate 50 can contact the lower part of the plug-in socket 40 and the second terminal block 30 (the bottom surfaces of the two can be arranged flush), so as to conduct through the first terminal block 20, the first conductive plate 401, the plug-in socket 40, the second conductive plate 50 to the second terminal block 30. When testing, use the actual The test rod is inserted into the through hole A. When the test rod squeezes open the raised part of the extrusion piece, since the extrusion piece does not contact other conductive parts, its position is limited and it can only deform in its mounting groove (a mounting groove is provided in the insulating shell, not shown in the figure. The extrusion piece is installed in the groove, and only the raised part can contact the test rod. When the test rod is squeezed, the extrusion piece is deformed and the spatial length becomes longer), so that the spatial length of the extrusion piece 60 becomes longer, thereby squeezing the second conductive plate 50 downward, so that the second conductive plate 50 is separated from the plug socket 40 and the second terminal socket 30, so that the disconnection operation can be realized. When the test rod is inserted into the plug socket 40, the instrument connected to the test rod can provide relevant signals (current or voltage) to increase the first terminal socket 20 and its wiring equipment. When the experiment is completed and the test rod is pulled out, the second conductive plate 50, under the action of the elastic member, reconnects the first terminal socket 20 and the second terminal socket 30, thereby realizing line recovery, which is simple and quick.

[0029] Furthermore, the first wiring slot 201 and the second wiring slot 301 are arranged in a bell-mouth shape on the outside, so that wiring can be conveniently performed.

[0030] Furthermore, the lower end of the extrusion piece 60 is fixedly connected to the upper surface of the second conductive plate 50 through the insulating plate 602. This prevents the experimental stick from affecting the instrument or device connected to the second wiring seat 30 when inputting or receiving signals.

[0031] Furthermore, the extrusion member 60 is a spring sheet, which has good properties, low price and is easy to use.

[0032] Furthermore, the elastic member 502 is a spring.

[0033] Furthermore, in order to facilitate fixation, a buckle 107 is provided on the rear end surface of the insulating housing 10 .

[0034] Furthermore, for easy identification, label slots 108 are provided at two corners of the insulating housing 10 .

[0035] The specific use principle is that first, the original circuit is disconnected. When the test rod is inserted into the upper part of the test hole A, the test rod squeezes the raised part of the spring sheet to deform, and the lower end of the spring sheet pushes toward the second conductive plate, so that the second conductive plate leaves the plug socket and the second wiring socket, thereby disconnecting the circuit;

[0036] Next, connect the test wire. When the test rod is further inserted into the plug socket, the circuit connection between the test rod and the first wiring slot in the first wiring socket is completed, and relevant experiments can be carried out.
