When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The present invention provides a universal electrical experiment module, which is mainly used in electrical experiment elements.

[0036] The electrical component 1 in the electrical experiment element can be any common laboratory electrical component 1, such as but not limited to an ammeter, a voltmeter, a resistor and a power switch, etc. When in use, the electrical component 1 is fixedly assembled at the assembly hole 213 of the universal electrical experiment module 2, and is electrically connected to the circuit board of the universal electrical experiment module 2 through the conductive part of the electrical component 1, so as to be electrically connected to the conductive magnetic beads 22 of the universal electrical experiment module 2. With such an arrangement, when the experimenter connects the lines of various experimental electrical components 1, the conductive magnetic beads 22 of adjacent universal electrical experiment modules 2 can be easily magnetically connected together to achieve the technical effect of electrical connection between the electrical components 1. At the same time, when disassembling the experimental circuit, it is only necessary to separate the conductive magnetic beads 22 that are magnetically attracted together. In this way, the efficiency of connecting and disassembling the circuits by the experimenter is simply and conveniently improved. At the same time, the regular module model also makes the connected circuits more ornamental.

[0037] The specific structure of an embodiment of the universal electrical experiment module 2 is described below. Figures 1 to 4 As shown, the universal electrical experiment module 2 includes:

[0038] The mounting shell is hollow; the mounting shell has a mounting surface 211 and a connecting surface 212, and the mounting surface 211 is provided with an assembly hole 213;

[0039] A circuit board is disposed in the mounting housing; and

[0040] The conductive magnetic bead 22 is at least partially disposed through the connection surface 212, the inner side of which is electrically connected to the circuit board, and the outer side is used to connect with the conductive magnetic bead 22 of another universal electrical experiment module 2; wherein,

[0041] The inner side of the assembly hole 213 is used for electrical connection with the circuit board, and the outer side is used for various electrical components 1 to be installed and fixed.

[0042] It can be understood that in this embodiment, the installation shell is preferably set in a cubic shape to ensure the stability of the installation shell structure. At the same time, such a setting is also convenient for the placement of the installation shell and the tight adsorption between the connecting surfaces 212. It should be noted that the present design is not limited to this. In other embodiments, the installation shell can also be other shapes such as a sphere, and there is no limitation on this; the conductive magnetic bead 22 is preferably a spherical shape that passes through the geometric center of the connecting surface 212. It is not difficult to understand that after the spherical conductive magnetic bead 22 is installed through the connecting surface 212, it can rotate freely on the installation surface 211, and when the two conductive magnetic beads 22 are magnetically adsorbed to each other, the two universal electrical experiment modules 2 can rotate 360° with each other, which brings convenience for the experimenter to adjust the placement angle of the experimental components by himself. Of course, the present design is not limited to this. In other embodiments, the conductive magnetic bead 22 can also be set in other shapes such as a cube, and the conductive magnetic bead 22 can also be arranged away from the geometric center of the connecting surface 212, and there is no limitation on this.

[0043] Without loss of generality, a fixing hole 213a is provided through the circuit board, and a fixing column adapted to the fixing hole 213a is provided on the inner wall of the mounting housing. The fixing column can be adapted to be plugged into the fixing hole 213a. This arrangement is convenient for fixing the circuit board in the mounting housing on the one hand, and the detachable installation between the fixing hole 213a and the fixing column also facilitates the experimenter to repair or replace the circuit board. Of course, the present design is not limited to this. In other embodiments, the circuit board can also be fixedly assembled in the mounting housing by other installation methods such as snap-on, and this is not limited.

[0044] Optionally, the mounting shell includes an upper cover body 214 , a lower cover body 216 , and a connecting surrounding wall 215 detachably assembled between the upper cover body 214 and the lower cover body 216 . It can be understood that the upper cover body 214 and the lower cover body 216 can be detachably assembled on the opposite sides of the connecting wall 215, respectively. Such an arrangement makes it convenient for users to disassemble, repair and replace components of the installation shell; specifically, the upper cover body 214 and the lower cover body 216 are both provided with a snap-in groove, and the connecting wall 215 is provided with a snap-in wall adapted to the snap-in groove so as to be snap-connected with the upper cover body 214 and the lower cover body 216. It should be noted that the present design is not limited to this. In other embodiments, the connecting wall 215 can also be connected and fixed to the upper cover body 214 and the lower cover body 216 by a hinge or other connection method, and there is no limitation on this; without loss of generality, the connecting wall 215 includes four connecting plates, namely, front, rear, left and right, and the structures of the plates are consistent and are independently connected to the upper cover body 214 and the lower cover body 216. Such an arrangement not only makes it easier to disassemble and assemble the components of the installation shell, but also the simple model of the plates is convenient for mass production in industry.

[0045] The universal electrical experiment module 2 of the technical solution of the present invention is provided with an assembly hole 213 on the installation surface 211 for various electrical components 1 to be installed and fixed, and a conductive magnetic bead 22 is provided through the connection surface 212, so that the circuit connection between the electrical component 1 and the conductive magnetic bead 22 is realized through the circuit board. In this way, the experimenter can realize the circuit connection between different electrical components 1 through the magnetic adsorption between the missile magnetic beads of the two universal electrical experiment modules 2, saving the time required for the installation and disassembly of the experimental circuit, which is conducive to improving the efficiency of the disassembly and assembly of the experimental circuit; in addition, the regular module model also makes the connected circuit more ornamental.

[0046] Optionally, the assembly hole 213 includes a fixing hole 213a and a conductive via 213b. The fixing hole 213a is used for the housing of various electrical components 1 to be installed and fixed, and the conductive via 213b is used for the conductive wires of various electrical components 1 to extend into the installation housing and be electrically connected to the circuit board. One of the conductive via 213b and the fixing hole 213a surrounds the other. It can be understood that installing and fixing the electrical component 1 outside the installation housing and realizing the electrical connection between it and the circuit board is a technical focus of this design. Through the assembly hole 213, different electrical components 1 can be assembled and fixed to improve the versatility of the universal electrical experiment module 2. Several common electrical components 1 are listed below for explanation. For example, a conductive switch can be threadedly locked with the annular shell of the conductive switch by protruding a thread on the hole wall of the conductive via 213b; for another example, an electric fan can be assembled by embedding the housing of the electric fan in the fixing hole 213a. Compared with the assembly method of installing and fixing the electrical component 1 in the installation shell, this design solves the problem of needing to produce universal electrical experiment modules 2 of different specifications due to different shapes and structures of different electrical components 1, and facilitates mass production of the process.

[0047] Without loss of generality, in this embodiment, the fixing hole 213a surrounds the conductive via 213b and is arranged at the geometric center of the mounting surface 211. This arrangement is to make the focus of the electrical component 1 fall on the central axis of the mounting shell, so as to avoid the unstable center of gravity of the mounting shell after installation affecting the placement of the universal electrical experiment module 2; it should be noted that the present design is not limited to this. In other embodiments, the fixing hole 213a and the conductive via 213b can also be separated from each other and set away from the geometric center of the mounting surface 211, and there is no limitation on this; after assembly, the conductive wire of the electrical component 1 is connected to the circuit board through the conductive hole, and the shell of the electrical component 1 extends into the fixing hole 213a and is fixed to the shell wall of the mounting surface 211. Of course, the present design is not limited to this. In other embodiments, the electrical component 1 can also be fixed to the mounting surface 211 by bonding or other connection methods, and there is no limitation on this.

[0048] Optionally, the fixing hole 213a is arranged to surround the conductive via 213b, and the mounting surface 211 is provided with a connecting arm 211a that penetrates the inner wall of the fixing hole 213a and is connected to the outer wall of the conductive via 213b, and the fixing hole 213a is arranged in a circular shape or a square shape. It can be understood that the connecting arm 211a plays a role in supporting and fixing the two hole walls, so that the hole wall of the conductive via 213b can more stably support the electrical component 1. Specifically, the fixing hole 213a includes a first ring hole and a second square hole, and one of the first ring hole and the second square hole surrounds the other. It is not difficult to understand that the length of the hole wall of the first ring hole and the second square hole is different from the hole wall of the conductive via 213b. Such an arrangement allows the housing of the electrical component 1 of different sizes and shapes to be fixed and installed. It should be noted that the present design is not limited to this. In other embodiments, the fixing hole 213a may also include multiple ring holes or square holes, and there is no limitation on this.

[0049] Optionally, the assembly hole 213 also includes a plurality of functional holes 213c arranged away from the fixing hole 213a and the conductive via 213b, and the radial dimensions of each functional hole 213c are smaller than the radial dimensions of the fixing hole 213a and the conductive via 213b. The functional holes 213c are used for the conductive wires of various electrical components 1 to extend into the mounting housing to be electrically connected to the circuit board, and the hole walls of the functional holes 213c are used for the housings of various electrical components 1 to be fixedly mounted. It can be understood that the apertures of the functional holes 213c and the conductive vias 213b are different, and the adapted electrical components 1 are also different. This arrangement is made so that the mounting surface 211 can adapt to more types of electrical components 1. Specifically, the mounting surface 211 is provided with a supporting wall for supporting the hole wall of the electrical component 1 through the hole wall of the functional hole 213c, so as to avoid the electrical component 1 from being embedded in the inner cavity of the mounting housing.

[0050] Optionally, the mounting shell includes at least two connection surfaces 212, and the universal electrical experiment module 2 is provided with a conductive magnetic bead 22 corresponding to each connection surface 212. It can be understood that the line connection of the electrical component 1 generally has a current input terminal and a current output terminal. In different circuit diagrams, the electrical component 1 is also divided into series and parallel. The present design sets a plurality of connection surfaces 212 to meet the connection requirements of different electrical components 1, thereby improving the practicality of the universal electrical experiment module 2. Without loss of generality, the present invention may also be provided with a plurality of mounting surfaces 211, so that common electrical components 1 can be combined and installed on the same mounting shell. For example, electrical components 1 that often need to be used together, such as power supplies and power switches, can be assembled on the same universal electrical experiment module 2, which is conducive to saving the cost required for the experiment.

[0051] Optionally, the mounting shell is in a cubic shape, the mounting surface 211 is formed on the top wall of the mounting shell, the two connecting surfaces 212 are formed on the side walls of the mounting shell, the circuit board is arranged facing the mounting surface 211 and connected to the two connecting surfaces 212, and the junctions between the circuit board and the two connecting surfaces 212 are provided with arc grooves to form an installation space for the conductive magnetic beads 22 to be embedded with the connecting surfaces 212. It can be understood that the groove wall of the arc groove has a plurality of conductive contacts electrically connected to the conductive magnetic beads 22, and the groove wall of the arc groove is in contact with the conductive magnetic beads 22 and is tightly arranged on the shell of the connecting surface 212. Such an arrangement avoids the situation that the conductive magnetic beads 22 are separated from the connecting surface 212 due to excessive mutual impact force when the conductive magnetic beads 22 are magnetically adsorbed with another conductive magnetic bead 22; specifically, the universal electrical experiment module 2 also includes a conductive spring electrically connected to the circuit board, and the conductive spring is installed between the groove wall of the arc groove and the conductive magnetic beads 22 to elastically press the conductive magnetic beads 22 to the connecting surface 212. It can be understood that the contact area (conductive area) between the conductive spring and the conductive magnetic bead 22 is larger than the cross-sectional area (conductive area) of the conductive contact, which is beneficial to improving the power supply reliability of the conductive magnetic bead 22. On the other hand, the elastic deformation function of the conductive spring itself enables the conductive magnetic bead 22 to provide a certain buffer space when the missile magnetic bead is subjected to external impact force, thereby preventing the shell wall of the installation shell, the conductive magnetic bead 22 or the circuit board and other devices from being damaged by the external impact force. It should be noted that the present design is not limited to this. In other embodiments, other conductive elastic materials can also be used instead of the conductive spring, and there is no limitation on this.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
