Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] This application provides a connection device for experimental equipment, see reference. Figure 1 As shown, the experimental equipment connection device provided in this application includes a connection structure 100 and a positioning structure. The connection structure 100 includes a first connection component and a plurality of second connection components. One end of the first connection component and the second connection component are respectively connected to the equipment element 600, and the other end are respectively connected to the equipment fixing seat 500. The second connection component is provided at an angle to the two adjacent sides of the equipment fixing seat 500. The positioning structure includes a first positioning element 210 and a second positioning element 220. One end of the first positioning element 210 is connected to the equipment element 600, and the other end is connected to one end of the second positioning element 220. The other end of the second positioning element 220 is connected to the equipment fixing base 500.

[0019] This application embodiment provides a connection structure 100 that can fix the equipment component 600 to the equipment mounting base 500 from multiple directions, thereby enhancing the stability of the connection between the equipment component 600 and the equipment mounting base 500 and preventing the equipment component 600 from shaking or shifting during use. A positioning structure provides precise positioning of the equipment component 600 relative to the equipment mounting base 500, ensuring that the equipment component 600 can be accurately installed in a preset position, improving the accuracy of experimental equipment installation. The cooperation between the connection structure 100 and the positioning structure ensures both the firmness of the connection between the equipment component 600 and the equipment mounting base 500 and achieves accurate positioning, making the experimental equipment more stable and reliable during use, and contributing to improved accuracy of experimental results.

[0020] In an optional embodiment, the first connection assembly includes a first connector 110 and a second connector 120. One end of the first connector 110 is connected to the equipment element 600, and the other end is connected to one end of the second connector 120. The other end of the second connector 120 is connected to the equipment mounting base 500. The second connection assembly includes a third connector 130 and a fourth connector 140. One end of the third connector 130 is connected to the equipment element 600, and the other end is connected to one end of the fourth connector 140. The other end of the fourth connector 140 is connected to the equipment mounting base 500. In one alternative embodiment, the first connector 110 and the second connector 120 are connected by a spring probe.

[0021] In this embodiment of the application, when the first connector 110 and the second connector 120 are connected as a spring probe, the first connector 110 is the needle shaft portion of the spring probe, and the second connector 120 is a mating portion adapted to the spring probe. When the first connector 110 and the second connector 120 need to be connected, the needle shaft portion of the spring probe moves toward the mating portion and contacts it. Under the action of elasticity, the needle shaft tightly abuts against the mating portion, thereby forming an electrical connection or a mechanical connection.

[0022] By employing a spring probe connection between the first connector 110 and the second connector 120, a tight contact between the two can be achieved through the spring force, ensuring the stability and reliability of the connection between the equipment mounting base 500 and the equipment component 600. The spring probe connection method also has good buffering performance; when subjected to a certain degree of vibration or slight displacement, the extension and contraction of the spring can compensate for positional deviations and maintain the connection status unaffected. Furthermore, the spring probe connection has a compact structure, which helps save installation space and is suitable for occasions with strict dimensional requirements.

[0023] In one optional embodiment, the third connector 130 and the fourth connector 140 are magnetically connected, wherein the third connector 130 is provided with a permanent magnet and the fourth connector 140 is provided with a ferromagnetic material, or; the third connector 130 is provided with a first magnetic element and the fourth connector 140 is provided with a second magnetic element, both the first and second magnetic elements are permanent magnets, and the end faces of the first and second magnetic elements that abut against each other are opposite magnetic poles.

[0024] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, a permanent magnet is provided on the third connector 130, and a ferromagnetic material is provided on the fourth connector 140. When the third connector 130 and the fourth connector 140 need to be connected, the permanent magnet on the third connector 130 and the ferromagnetic material on the fourth connector 140 are brought close together. The permanent magnet will attract the ferromagnetic material, thereby achieving a magnetic connection between the third connector 130 and the fourth connector 140. Alternatively, a first magnetic element is provided on the third connector 130, and a second magnetic element is provided on the fourth connector 140. Both the first and second magnetic elements are permanent magnets, and the end faces of the first and second magnetic elements that abut against each other are opposite magnetic poles. When the third connector 130 and the fourth connector 140 need to be connected, the end faces of the first and second magnetic elements that abut against each other are brought close together. Due to the attraction between opposite magnetic poles, the first and second magnetic elements will attract each other, thereby achieving a connection between the third connector 130 and the fourth connector 140.

[0025] Furthermore, the magnetic connection of the third connector 130 and the fourth connector 140 enables the equipment component 600 to be quickly connected to the equipment mounting base 500. The connection process is simple and does not require complicated operation steps. In addition, the magnetic connection has good stability and can maintain the connection state without being subjected to large external forces, making it difficult to separate.

[0026] In one optional embodiment, the first positioning element 210 is a positioning hole, and the second positioning element 220 is a first positioning post.

[0027] Furthermore, the positioning hole is a stepped hole, and the first positioning post is a stepped shaft that is adapted to the positioning hole.

[0028] In the embodiments of this application, such as Figure 1 and 2As shown, the positioning structure also includes a first positioning element 210 and a second positioning element 220. The first positioning element 210 and the second positioning element 220 enhance the overall stability of the equipment fixing base 500 and the equipment element 600, ensuring reliable use under different conditions. The first positioning element 210 and the second positioning element 220 also add fixing points for the equipment element 600 on the equipment fixing base 500, thereby strengthening the overall stability of the experimental equipment and preventing the equipment element 600 from shaking due to force during use, thus ensuring the accuracy and safety of the experimental process.

[0029] In one alternative embodiment, one end of the first connector 110 is connected to the first identification circuit 300 in the equipment element 600; one end of the second connector 120 is connected to the second identification circuit 400 in the equipment mounting base 500; the first identification circuit 300 and the second identification circuit 400 are electrically connected through the connection structure 100. In this embodiment, the first identification circuit 300 includes a sampling auxiliary resistor and an identification terminal connected to the sampling auxiliary resistor; the second identification circuit 400 includes an identification resistor and a first capacitor connected to the identification resistor; further, the identification resistor includes a first identification resistor and / or a second identification resistor.

[0030] In practical implementation, for example, the experimental equipment is a knife switch. The equipment mounting base 500 of the knife switch is provided with a first identification circuit 300 interface (i.e., a first connector), and the equipment component 600 is provided with a second identification circuit 400 interface (i.e., a second connector). Both the first identification circuit 300 interface and the second identification circuit 400 interface are spring pin interfaces. The first identification circuit 300 interface J1 corresponds to the first identification circuit 300 as follows: Figure 3 As shown, the first identification circuit 300 includes a sampling auxiliary resistor R31, a power supply terminal, and a communication pin. The power supply terminal includes a positive power supply VCC and a negative power supply GND, which provides operating power to the first identification circuit 300 and the second identification circuit 400 to ensure stable loop current. One end of the sampling auxiliary resistor R31 is connected to the communication pin 9, and the other end is connected to the second identification circuit 400 through the communication pin 3. The sampling auxiliary resistor R31 is used to limit the current input from the second identification circuit 400 to the first identification circuit 300 to prevent excessive input current from damaging the equipment mounting base 500 and to ensure the stability and reliability of the identification circuit. The second identification circuit 400 interface corresponds to the second identification circuit 400, such as... Figure 4 As shown, the second identification circuit 400 includes a first identification resistor R5, a second identification resistor R3, and a first capacitor C1. The first identification resistor R5 and the second identification resistor R3 form a resistor network with a specific resistance value, which is used to determine the type and model of the experimental equipment. The first capacitor C1 is used to eliminate interference signals to ensure accurate measurement of the resistance value of the resistor network. When the equipment component 600 is a knife switch, after the interfaces of the first identification circuit 300 and the second identification circuit 400 are connected, the sampling auxiliary resistor R31 of the first identification circuit 300 is connected to the first identification resistor R3 and / or the second identification resistor R5 in the second identification circuit 400 to determine that the current experimental equipment is a knife switch of a certain model.

[0031] It should be noted that different types and models of experimental equipment can form the same type and model of experimental equipment by setting different resistance values ​​or combinations of resistances, thus forming a unique resistance network characteristic. That is, the same type and model of experimental equipment has a unique resistance value.

[0032] This application also provides an experimental apparatus, see the attached embodiment. Figure 5 As shown, the experimental equipment provided in this application embodiment includes a connecting device, an equipment element 600, and an equipment fixing base 500; the equipment element 600 is connected to the equipment fixing base 500 through the connecting device.

[0033] In this embodiment, the equipment element 600 includes, but is not limited to, experimental equipment switches, sliding rheostats, and voltmeters.
