[0023] Please see Figure 1-4 In this embodiment: a wire testing device for electronic and electrical teaching includes a main body 1, a display screen 2 on the main body 1, a pad 3 at the bottom of the main body 1, a wire tray 4 between the pads 3, a mounting opening 5 on the main body 1, a socket module 6 inside the mounting opening 5, a sliding groove 7 on the inner side of the pad 3, a protrusion 8 on the wire tray 4, a first contact 9 inside the mounting opening 5, a first magnet 10 inside the mounting opening 5, a second contact 11 on one side of the socket module 6, and second magnets 12 at both ends of the socket module 6;
[0024] The main body 1 can be supported by the pad 3, and the wiring tray 4 can be easily slidably installed by the slide groove 7. The specific model of the main body 1 is TH8602.
[0025] The protrusion 8 includes a buffer cavity 801, a mounting ring 802 and a spring 803. The mounting ring 802 is provided on the outer side of the protrusion 8, and the spring 803 is provided between the mounting ring 802 and the buffer cavity 801.
[0026] The mounting ring 802 can be supported by the spring 803, and the mounting ring 802 can be deflected when force is applied and smoothly reset when no force is applied.
[0027] In this embodiment, the pad 3 is fixedly installed at the bottom of the main body 1 and there are two sets in total. The wiring tray 4 is adapted to the slide groove 7 on both sides. Two sets of first contact 9 are embedded in the mounting port 5. The first contact 9 is electrically connected to the internal circuit of the main body 1. Two sets of second contact 11 are embedded on one side of the socket module 6. The second contact 11 is electrically connected to the socket module 6. The second contact 11 and the first contact 9 are both made of iron.
[0028] Specifically, the mounting port 5 facilitates the installation of the socket module 6, and the first contact 9 and the second contact 11 ensure the power supply of the socket module 6.
[0029] In this embodiment, there are two sets of first magnets 10, which are fixedly embedded in the two side walls of the mounting port 5. The second magnet 12 is fixedly embedded in both ends of the socket module 6. There is magnetic attraction between the first magnet 10 and the second magnet 12. There are several sets of socket modules 6, and the sockets are different. Each set of socket modules 6 is provided with a second contact 11 and a second magnet 12. There are several sets of protrusions 8, which are fixedly installed on the wiring tray 4. The buffer cavity 801 is adapted to the mounting ring 802.

At this time, the wire will exert pressure on the mounting ring 802. After being subjected to force, the mounting ring 802 will sink into the buffer cavity 801, which can make the wire stuck between the protrusions 8, providing stable arrangement conditions for the wire, avoiding wire mess, and facilitating management. At the same time, when testing is required... When testing with wires having different ends, the connector module 6 can be removed from the mounting port 5 and replaced with a new connector module 6 to adapt to the end of the corresponding wire. The new connector module 6 is then placed in the mounting port 5, and the second contact 11 is brought into contact with the first contact 9, and the second magnet 12 is brought into contact with the first magnet 10 to form a magnetic attraction, ensuring the stable installation of the newly installed connector module 6.
