Description

Technical Field

[0001] This utility model relates to electrical connection structures, specifically to an electrical connection component and a spliced ​​electrical component. Background Technology

[0002] In recent years, some new types of modular electrical products have emerged, such as modular lighting fixtures. These consist of a power base and multiple different light-emitting units, which users can select and connect to the base to create lighting fixtures with different lighting effects. Another example is modular magnetic toy blocks; by magnetically attaching multiple toy blocks and connecting them to a power source, they can emit light or sound. These modular products expand the functionality of existing products and provide users with a novel experience, but some shortcomings still exist.

[0003] Specifically, these modular electrical components typically have exposed electrodes to allow users to make contact with the electrodes during physical assembly, thus establishing a current path. Inside these components, the electrodes are electrically connected to internal circuit boards, light-emitting devices, and other components via multiple conductive wires, forming multiple electrical contacts, such as solder joints, between these conductive wires and the circuit boards. As can be seen, the internal electrical connection structure of these modular electrical components is quite complex. Since these components are frequently moved and assembled, and toy pieces are inevitably subject to bumps and drops, the internal conductive wires move and vibrate accordingly. Over time, this can lead to poor contact or even wire breakage, causing the modular electrical component to lose its electrical function and resulting in a poor user experience.

[0004] On the other hand, light-emitting products such as light-emitting toy pieces and modular lamps need to allow light to pass through, so their outer shells are usually made of materials with a certain degree of transparency, which allows some of the internal structure to be seen. As a result, users can see the rather messy conductive wire structure inside, which also leads to the poor appearance of these products. Utility Model Content

Detailed Implementation

[0057] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the electrode frame and spliced ​​electrical components of this utility model will be specifically described below in conjunction with the embodiments and accompanying drawings.

[0058] Example 1

[0059] Figure 1 This is a perspective view of the modular electrical components in this embodiment. Figure 2 This is an exploded view of the modular electrical components in this embodiment. Figure 3 This is an exploded view of the spliced ​​electrical components from different angles in this embodiment.

[0060] like Figures 1 to 3 As shown, the interlocking electrical component 100 in this embodiment is a magnetic interlocking piece used as a toy, which includes a housing 1, multiple magnetic components 2, an electrical connection assembly 4, and a functional component 6.

[0061] The housing 1 includes a base 11 and a cover plate 12 that match each other. In this embodiment, the housing 1 is generally a square plate with rounded corners.

[0062] The base 11 is polygonal in shape, with one side being an open side. In this embodiment, it is a square cover with rounded corners, having a roughly square base plate and a square ring-shaped side plate extending roughly perpendicularly from the edge of the base plate, forming four sides of roughly the same length. The inner side of the base 11 forms an installation structure, including multiple base fixing holes 111, multiple magnetic accommodating slots 112, multiple electrode mounting slots 113, and base frame fitting slots 114.

[0063] The base fixing holes 111 are provided at each corner of the base 11. A cylindrical protrusion is formed at each corner of the inner side of the base 11, and the base fixing hole 111 is formed in the middle of the cylindrical protrusion. It is a circular through hole that runs through the thickness direction of the base 11.

[0064] A magnetic accommodating groove 112 is disposed on at least one side of the base 11. An elongated strip-shaped protrusion parallel to the side and a short strip-shaped protrusion perpendicular to the side are formed on the inner side of the side of the base 11. Two adjacent magnetic accommodating grooves 112 are formed between the side plate of the base 11, the elongated strip-shaped protrusion, and the short strip-shaped protrusion. These grooves are rectangular and their length direction is consistent with the length direction of the side. In this embodiment, two magnetic accommodating grooves 112 are formed on each side.

[0065] One or more pairs of electrode mounting slots 113 are disposed on one or more sides of the base 11, and on the side having magnetic accommodating slots 112. A pair of generally rectangular notches are formed on the side of the base 11, and two generally trapezoidal sidewalls are formed on both sides of the notches. The sidewalls are perpendicular to the surface direction of the base 11 and perpendicular to the length direction of the side. Electrode mounting slots 113 are formed between the two sidewalls and the bottom plate of the base 11. In this embodiment, a pair of electrode mounting slots 113 are formed on each side, and the pair of electrode mounting slots 113 are respectively disposed near the two corners connected to the side. The two magnetic accommodating slots 112 of the side are located between the pair of electrode mounting slots 113.

[0066] The base frame fitting groove 114 is located in the middle of the inner bottom surface of the base 11. In this embodiment, the four long strip-shaped protrusions on the inner side of the four sides of the base 11 surround and form the frame fitting groove 114, which is a rounded square groove with a groove depth less than the thickness of the base 11.

[0067] The cover plate 12 is a plate with a protrusion on one side, matching the shape of the base 11, and is used to fit into the open side of the base 11 to form a closed shell 1, forming an inner cavity 3 inside the shell 1. In this embodiment, the cover plate 12 is also a rounded square plate, and also has four sides of substantially the same length. The cover plate 12 has a mounting structure, including multiple cover plate fixing holes 121, multiple magnetic suction receiving grooves 122, multiple electrode mounting grooves 123, and cover plate frame fitting grooves 126.

[0068] Cover plate fixing holes 121 are provided at each corner of cover plate 12. Cylindrical protrusions are formed at each corner on one side of cover plate 12. Cover plate fixing holes 121 are formed in the middle of the cylindrical protrusions. They are circular through holes that extend along the thickness direction of cover plate 12.

[0069] A magnetic accommodating groove 122 is provided on at least one edge of the cover plate 12 and corresponds to the magnetic accommodating groove 112 on the base 11. A long strip-shaped protrusion parallel to the edge and a short strip-shaped protrusion perpendicular to and connected to the long strip-shaped protrusion are formed on one side edge of the cover plate 12. Two adjacent magnetic accommodating grooves 122 are formed between the long strip-shaped protrusion and the short strip-shaped protrusion. The long strip-shaped protrusion and the short strip-shaped protrusion are semi-open rectangular grooves that match the magnetic accommodating grooves 112.

[0070] One or more pairs of electrode mounting grooves 123 are provided on one or more edges of the cover plate 12 and are correspondingly provided with electrode mounting grooves 113 on the base 11. A pair of rectangular notches are formed on the edge of the cover plate 12, and two roughly trapezoidal sidewalls are formed on both sides of the rectangular notches. The sidewalls are perpendicular to the surface direction of the cover plate 12 and perpendicular to the length direction of the edge on which they are located. Electrode mounting grooves 123 are formed between the two sidewalls and the bottom plate of the cover plate 12.

[0071] The cover plate frame fitting groove 126 is located in the middle of the inner bottom surface of the cover plate 12. In this embodiment, the four long strip-shaped protrusions on the inner side of the four sides of the cover plate 12 surround and form the cover plate frame fitting groove 124, which is a shallow, rounded square groove.

[0072] When the cover plate 12 is fitted onto the base 11 to form the shell 1, the base fixing hole 111 and the corresponding cover plate fixing hole 121 combine to form a through fixing hole for mounting the fixing component. The magnetic component receiving groove 112 and the corresponding magnetic component receiving mating groove 122 combine to form a magnetic component receiving cavity, which is a cuboid cavity for mounting a cuboid magnetic component 2.

[0073] Furthermore, the center of the largest surface of the base 11 is recessed towards the interior of the housing 10, and the center of the surface of the cover plate 12 is recessed towards the interior of the housing 10. This allows the edges of the two spliced ​​electrical components 100 to effectively contact each other when they are stacked along their thickness direction. In this embodiment, the base plate of the base 11 includes multiple triangular plate-shaped portions, and the center of the cover plate 12 also includes multiple triangular plate-shaped portions, such that their centers are recessed towards the interior of the housing 10.

[0074] The electrode mounting groove 113 and the corresponding electrode mounting mating groove 123 are combined to form the electrode engaging part 13. The electrode engaging part 13 includes an electrode engaging notch 131 and an electrode engaging hole 132.

[0075] Figure 4 This is a perspective view of the housing in this embodiment.

[0076] like Figure 4 As shown, the edge of the housing 1 is polyhedral in shape, with multiple sequentially connected facets. The electrode engagement notch 131 forms a rectangular opening on each facet. In this embodiment, the edge of the housing 1 has three facets, and the electrode engagement notch 131 forms three openings on each of the three facets. The electrode engagement hole 132 is a rectangular through hole that extends along the length or width of the housing 1. Each electrode engagement hole 132 connects the corresponding electrode engagement notch 131 and the inner cavity of the housing 1. The width of the electrode engagement hole 132 in the thickness direction of the housing 1 is less than the thickness of the housing 1.

[0077] Figure 5 This is a partial cross-sectional view of the spliced ​​electrical components in this embodiment. Figure 6 This is an exploded view of the electrical connection components and functional components in this embodiment.

[0078] like Figures 2 to 6 As shown, the electrical connection assembly 4 includes two identical electrode frames and an isolation frame 42. The two electrode frames are used as a positive electrode frame 41 and a negative electrode frame 43, respectively. The isolation frame 42 is used to isolate the two electrode frames to prevent them from contacting each other and causing a short circuit. The positive electrode frame 41, the isolation frame 42, and the negative electrode frame 43 are stacked in sequence.

[0079] Figure 7 This is a perspective view of the positive electrode frame in this embodiment.

[0080] like Figure 6 and Figure 7 As shown, the positive electrode frame 41 includes a frame 410 and a plurality of positive electrodes 51.

[0081] The frame 410 includes a frame body 411, multiple conductive contact portions 412, multiple conductive connection portions 413, multiple positioning portions 414, and multiple clearance notches 415.

[0082] The frame body 411 is a polygonal frame with a relatively thin line width, and has multiple flat elongated strip-shaped sides and multiple corners. In this embodiment, the frame body 411 is a rounded square frame with four sides of approximately the same length and uniform line width, and the entire frame body 411 is on the same plane.

[0083] Figure 8 yes Figure 7 Enlarged view of the inner part of frame A.

[0084] like Figures 6 to 8As shown, the conductive contact portion 412 extends from the same side of the frame body 411 and has a conductive contact surface 412a for contacting the conductive end of the electrical device to achieve electrical connection. In this embodiment, the conductive contact portion 412 consists of two strip-shaped protrusions, respectively disposed at two adjacent corners of the frame body 411. The length direction of the conductive contact portion 412 is the diagonal direction of the corner, and both ends of its length direction have an arc corresponding to the corner of the frame body 411. The outer end face of the conductive contact portion 412 is the conductive contact surface 412a, which is a plane parallel to the surface direction of the frame body 411.

[0085] A conductive connection portion 413 is disposed on at least a portion of the outer surface of the frame body 411, for conductively connecting the conductive contact surface 412a of the conductive contact portion 412 to the positive electrode 51. In this embodiment, the positive electrode frame 41 is integrally formed, with its interior being a non-metallic material integrally molded part, such as a plastic part, and its outer surface being a metallic conductive layer, such as a metal plating layer. That is, the conductive connection portion 413 covers the entire surface of the frame body 411, and the conductive connection portion 412, the conductive layer on the surface of the positive electrode 51, and the conductive layer on the surface of the conductive contact portion 412 are integrally formed metallic conductive plating layers. In an alternative embodiment, the conductive connection portion 413 may also be disposed only on a portion of the outer surface of the frame body 411, or the conductive connection portion 413 may also be disposed inside the frame body 411, as long as it can connect the conductive layer of each positive electrode 51 to each conductive contact surface 412a.

[0086] The positioning part 414 is a positioning post, which is a small cylinder with a hemispherical outer end. Multiple positioning posts extend from the same side of the frame body 411, and their extension direction is perpendicular to the surface direction of the frame body 411. In this embodiment, each side of the frame 410 has two positioning posts, which are respectively arranged relatively close to the two corners connected to the side, and the distance between the two positioning posts and the corresponding corners is different.

[0087] like Figure 8 As shown, the clearance notch 415 is a rectangular notch formed on the side of the frame 410, and its opening faces outward. It is used to avoid the negative electrode 52 when assembled, so that the two electrode frames can not contact each other at all, thereby avoiding short circuit.

[0088] The positive electrode 51 extends outward from the edge or corner of the frame 410, and is used to contact the positive electrodes of other spliced ​​electrical components to form a conductive circuit. For example... Figures 6 to 8 As shown, in this embodiment, each positive electrode 51 is an irregularly shaped block extending outward from the edge of the frame 410. Each positive electrode 51 includes an electrode fixing part 511 and an electrode contact part 512.

[0089] The electrode fixing part 511 is fixed to the frame 410 and is used to snap into the housing 1 to fix the electrical connection assembly 4. In this embodiment, the electrode fixing part 511 is generally T-shaped, with one end fixed to one side of the frame 410. The height of the electrode fixing part 511 in the thickness direction of the housing 1 is significantly greater than the thickness of the frame 211. A snap-fit ​​groove 5111 (positioning groove) is formed on the electrode fixing part 511. It is a rectangular groove that extends along the length direction of the side of the frame 211. The portion of the positive electrode 51 with the snap-fit ​​groove 5111 matches the electrode snap-fit ​​hole 132.

[0090] The electrode contact portion 512 extends further outward from the other end of the electrode fixing portion 511. In this embodiment, it is in the shape of a cuboid block. The width of the electrode contact portion 512 in the corresponding side length direction of the housing 1 is the same as the width of the electrode fixing portion 511. Its height in the thickness direction of the housing 1 is greater than the height of the electrode fixing portion 511, forming a step between the two. Furthermore, the height of the electrode contact portion 512 is also slightly greater than the thickness of the edge of the housing 1.

[0091] The electrode contact portion 512 has one or more electrode contact surfaces 512a, and its shape matches the electrode engagement notch 131, allowing it to engage in the corresponding electrode engagement notch 131. The electrode contact surfaces 512a are exposed through openings on the respective edge faces. In this embodiment, the electrode contact portion 512 is cuboid in shape, with three sequentially connected electrode contact surfaces 512a, and a rounded transition between adjacent electrode contact surfaces 512a. The three electrode contact surfaces 512a are exposed through three openings on the three edge faces of the electrode engagement notch 131. Furthermore, the width of the electrode contact portion 512 in the length direction of the corresponding edge is approximately equal to the width of the electrode engagement notch 131, the height of the electrode contact portion 512 in the thickness direction of the housing 1 is slightly greater than the thickness of the housing 1, and the length of the electrode contact portion 512 is slightly greater than the length of the electrode engagement notch 131, so that the three electrode contact surfaces 512a are located further outward relative to the corresponding three edge faces.

[0092] In this embodiment, the positive electrode frame 41 has four positive electrodes 51. A positive electrode 51 is provided on each side of the frame 410. Each positive electrode 51 is located near the corner of the frame 410. The protruding direction of each positive electrode 51 is perpendicular to the length direction of the side it is located on and parallel to the surface direction of the frame 410.

[0093] Two positive electrodes 51 are respectively provided on both sides of one corner of the frame 410. The other corner opposite to this corner (i.e., the other corner located on the same diagonal) does not have positive electrodes 51, but has two clearance notches 415 on both sides. Each of the other two corners of the frame 410 has one positive electrode 51 and one clearance notch 415 on one side.

[0094] The structure of the negative electrode frame 43 is exactly the same as that of the positive electrode frame 41. That is, the negative electrode frame 43 also includes a frame body 430 and a plurality of negative electrodes 52 disposed on the frame body 430. The frame body 430 also has a plurality of conductive contact portions 432, a plurality of positioning portions 434, and a plurality of clearance notches 435, and their distribution and the distribution of the plurality of negative electrodes 52 are exactly the same as the distribution of the corresponding portions in the positive electrode frame 41. Furthermore, the positive electrode frame 41 and the negative electrode frame 43 have a flip-symmetric structure. The plurality of electrodes and the plurality of clearance notches are flip-symmetrically arranged along the axis of symmetry of the frame body. That is, after the positive electrode frame 41 is flipped 180 degrees along axis O1, each positive electrode 51 is located at the position of each clearance notch 415 of the positive electrode frame 41 before the flip, and each clearance notch 415 is also located at the position of each positive electrode 51 of the positive electrode frame 41 before the flip.

[0095] These two identical electrode frames are designated as positive electrode frame 41 and negative electrode frame 43, respectively, and are arranged as follows: Figure 2 and Figure 3 When the three layers of the frame are arranged and stacked as shown, the multiple positive electrodes 51 and multiple negative electrodes 52 are staggered in the stacking direction. Each side of the stacked three-layer frame is provided with a positive electrode 51 and a negative electrode 52. The positive electrode 51 is set to correspond to the clearance notch 415 on the negative electrode frame 52, and the negative electrode 52 is set to correspond to the clearance notch 415 on the positive electrode frame 41, so that each electrode will not come into contact with the electrode frame of the opposite electrode.

[0096] Furthermore, the conductive metal plating on the two electrode frames can be different colors, so that the exposed positive electrode 51 and negative electrode 52 are also different colors, allowing users to easily identify the positive and negative electrodes during use. For example, one of the two electrode frames can have a gold plating, and the material of the gold plating can be, for example, copper or a copper-zinc alloy; the other of the two electrode frames can have a silver plating, and the material of the silver plating can be, for example, aluminum, zinc or a zinc alloy.

[0097] In alternative solutions, the electrode frames can also be of other shapes, and the distribution of electrodes, conductive contacts, and clearance notches can also differ, as long as the electrode frames have a certain axisymmetric structure, allowing the two electrode frames to be stacked after one of the electrode frames is flipped, and the electrodes and clearance notches of the two electrode frames to correspond in the stacking direction. The following variations will exemplarily show some other shapes of electrode frames.

[0098] The isolation frame 42 is also a polygonal frame with a narrower line width, matching the frame of the electrode frame. In this embodiment, it is also a rounded square frame, and has multiple contact mating parts 421, multiple positioning mating parts 422, and multiple clearance notches 423.

[0099] Multiple contact mating portions 421 are respectively disposed on both sides of the isolation frame 42, and are respectively disposed corresponding to the conductive contact portions on the two electrode frames. In this embodiment, the contact mating portion 421 is a strip-shaped groove that matches the conductive contact portions 412 and 432 (strip-shaped protrusions), and each strip-shaped groove extends approximately along the diagonal direction of the corresponding corner and is continuous. Two contact mating portions 421 are disposed on each side of the isolation frame 42, and the two contact mating portions 412 on each side are respectively disposed at two adjacent corners of the isolation frame 42. In an alternative embodiment, the conductive contact portion can be disposed as a groove, and the conductive mating portion can be disposed as a corresponding protrusion.

[0100] The positioning mating parts 422 are in two sets, each corresponding to a positioning part on one of the two electrode frames, and are used to cooperate with the positioning parts to fix and position the two electrode frames and the isolation frame 42. In this embodiment, the positioning mating parts 422 are positioning holes that extend along the thickness direction of the isolation frame 42, and are provided with two sets of positioning holes, namely first positioning holes 422a and second positioning holes 422b. Two first positioning holes 422a and two second positioning holes 422b are distributed on each side of the isolation frame 42. In an alternative embodiment, positioning posts can be formed on both sides of the isolation frame 42, and corresponding positioning holes can be formed on the two electrode frames.

[0101] The clearance notch 423 is provided on the edge of the isolation frame 42 with its opening facing outward. Multiple clearance notches 423 are respectively provided to correspond to multiple electrodes on the two electrode frames, and are used to make way for the electrodes during assembly.

[0102] In an alternative solution, the isolation frame 42 may be omitted if the positive electrode frame 41 and the negative electrode frame 43 do not make conductive contact. For example, the positive electrode frame 41 and the negative electrode frame 43 may be fitted or bonded to the two inner surfaces of the housing 1 respectively, with a distance between them so that they do not make contact; or, the conductive layer may be mainly formed on the upper surface of the positive electrode frame 41 and the lower surface of the negative electrode frame 43, and no conductive layer may be formed on the positive electrode frame 41 at the position corresponding to the conductive contact portion of the negative electrode frame 43, and similarly, no conductive layer may be formed on the negative electrode frame 43 at the position corresponding to the conductive contact portion of the positive electrode frame 41; or an insulating layer may be formed at the above-mentioned positions of the two electrode frames. In this way, the positive electrode frame 41 and the negative electrode frame 43 may be directly stacked without making conductive contact, and the isolation frame 42 may not be required.

[0103] Functional component 6 is used to realize a predetermined electrical function, such as realizing light emission, sound emission, display, user interaction, or a combination of two or more of the above functions. In this embodiment, functional component 6 is used to realize the light emission function, and it includes a power supply frame 161 and multiple light-emitting devices 162. Functional component 6 is housed in housing 1 and is fixed and electrically connected by electrical connection component 4. In order to allow the light emitted by functional component 6 to pass through to the outside of housing 1, housing 1 is correspondingly a transparent or translucent housing, such as a translucent or transparent plastic housing.

[0104] The power supply frame 161 comprises multiple elongated frame sections. Each power supply frame 161 has at least one positive connection end 17 (positive pole) and at least one negative connection end 18 (negative pole), located at opposite ends of the frame sections. The shapes of the positive connection end 17 and the negative connection end 18 match the shape of the conductive contact portion 2112. In this embodiment, the power supply frame 161 is X-shaped, meaning it has four frame sections extending from a central point, with two positive connection ends 17 and two negative connection ends 18 at the ends of the four frame sections.

[0105] Both the positive connection end 17 and the negative connection end 18 are strip-shaped pieces that match the contact surface of the conductive contact portion of the electrode frame and the contact mating portion 221 (groove) of the isolation frame 42, and the positive and negative symbols are marked on the surface.

[0106] Multiple light-emitting devices 162 are respectively installed on each frame of the power supply frame 161. In this embodiment, the light-emitting device 162 is an LED lamp. Each frame has a light-emitting device 162 installed on both sides, so that the spliced ​​electrical component 100 can emit light on both sides when current passes through.

[0107] The specific structure of the power supply frame 161 and the light-emitting device 162 is existing technology, for example, existing flexible LED light strips can be used, so it will not be described in detail.

[0108] In an alternative, functional component 6 may also include two elongated power supply frames 161, with a positive connection terminal 17 and a negative connection terminal 18 at each end. Two sets of light-emitting devices 162 are provided on each power supply frame 161. The two power supply frames 161 can be overlapped into an X shape to form a similar light-emitting functional component.

[0109] In alternative solutions, the power supply bracket 161 can also be in other shapes to achieve different lighting effects, such as a strip shape, a cross shape, a star shape, a flower shape, a polygon (triangle, rectangle, pentagon, hexagon, etc.), a character shape (e.g., in the shape of numbers, operators, letters or words), a pattern shape (e.g., in the shape of a logo, or in the shape of a simple line drawing of animals or plants), or a combination of two or more of the above shapes.

[0110] In alternative solutions, functional component 6 can also be used to implement other electrical functions, such as power supply (i.e., built-in energy storage devices), light emission, sound emission, display, user interaction, or a combination of two or more of the above functions.

[0111] Multiple magnetic attractors 2 are respectively disposed in each magnetic attractor receiving cavity, so that two spliced ​​electrical components 100 can be spliced ​​together by magnetic attraction. The magnetic attractor 2 is a cuboid magnet that matches the magnetic attractor receiving cavity, preferably a permanent magnet. In this embodiment, the magnetic attractor 2 is magnetized along its own thickness direction, so that its two ends along the thickness direction are N pole and S pole respectively. In the two magnetic attractor accommodating cavities on each side of the housing 1, the two magnetic attractors 2 are installed in a complementary polarity manner. That is, the N pole of one magnetic attractor 2 is embedded towards the bottom of the magnetic attractor receiving groove 112, and the other magnetic attractor 2 is rotated 180° relative to it so that its S pole is embedded towards the bottom of the magnetic attractor receiving groove 112. The two magnetic attractors 2 at each edge follow the above magnetic pole configuration rules to ensure the symmetry of the magnetic pole distribution on each edge of the spliced ​​electrical component 100. This layout allows the magnetic attractor of adjacent spliced ​​electrical components 100 to form a complementary polarity with the magnetic attractor on the corresponding edge of the adjacent spliced ​​electrical component 100 when they are connected by the edges, even if one of them is rotated 180°, its magnetic attractor can still form a complementary polarity with the magnetic attractor on the corresponding edge of the adjacent spliced ​​electrical component 100, thereby achieving reliable adsorption.

[0112] In alternative solutions, modular electrical components may not have magnetic attachments, but can be joined together in other ways, such as having interlocking or snap-fit ​​structures at their edges, or having adhesive structures such as Velcro.

[0113] like Figure 2As shown, when the electrical connection assembly 4 and the functional assembly 6 are assembled as a whole, the frame 410 of the positive electrode frame 41, the isolation frame 42, and the frame 430 of the negative electrode frame 43 are stacked sequentially. Multiple positioning posts on the two electrode frames are inserted into a corresponding set of positioning holes on the isolation frame 42, thereby fixing and positioning the three frames so that they are approximately in contact and aligned in the stacking direction. One end of the electrode fixing part 511, fixed to the frame, is placed in the corresponding clearance notch 423 of the isolation frame 42 and the corresponding avoidance notch of the other electrode frame, ensuring that the electrode does not contact the frame of the other electrode frame. The positive connection end 17 and negative connection end 18 of the functional component 6 are respectively embedded in the corresponding contact mating part 421 (groove), and the conductive contact part (strip-shaped protrusion) of the electrode frame is also embedded in the corresponding contact mating part 421 (groove). The conductive contact surface 2112a is in contact with the positive connection end 17 or the negative connection end 18, so that the functional component 6 is electrically connected to the positive electrode frame 41 and the negative electrode frame 43 respectively. The functional component 6 can be powered (i.e., the functional component 6 includes electrical components) or the electrical energy of the functional component 6 can be released (i.e., the functional component 6 includes energy storage devices) through the positive electrode 51 and the negative electrode 52.

[0114] When the electrical connection assembly 4 is assembled in the housing 1, the frame 410 of the positive electrode frame 41 is fitted into the cover frame fitting groove 126, and the frame 430 of the negative electrode frame 43 is fitted into the base frame fitting groove 114. The parts of each electrode with snap-fit ​​grooves are respectively snapped into the corresponding electrode snap-fit ​​holes 132, and the electrode contact parts of each electrode are respectively snapped into the corresponding electrode snap-fit ​​notches 131, thereby fixing the three-layer frame and fixing and positioning each electrode from multiple directions. As mentioned above, the three electrode contact surfaces 512a of each electrode are exposed through the electrode snap-fit ​​notches 131, and each electrode contact surface 512a is located further outward relative to the corresponding edge, thereby ensuring effective contact between the electrodes of the two spliced ​​electrical components 100 when they are spliced ​​together.

[0115] In an alternative, the edge of the housing 1 can also be in other shapes, such as a polyhedron with more facets, and the electrode correspondingly having more electrode contact surfaces, each of which is exposed from the corresponding facet and located further out; or it can be an arc surface (e.g., a circular arc surface or an elliptical arc surface), with the electrode contact surface of the electrode being the corresponding arc surface, exposed from the arc surface of the housing and located further out.

[0116] In this embodiment, the side length of the housing 1 is 70mm to 90mm, and there is no particular limitation on the side length of the housing 1; the thickness of the housing 1 is 5mm to 10mm. The width of the electrode engaging notch 131 is 2mm to 5mm, preferably 3mm, and the widths of the positive electrode 51 and the negative electrode 52 are corresponding dimensions. The height of the electrode engaging hole 132 in the thickness direction of the housing 1 is 3mm to 6mm, and the dimensions of the engaging grooves of the positive electrode 51 and the negative electrode 52 are corresponding dimensions.

[0117] The positive electrode frame 41 has a side length of 50mm to 70mm and a line width of 1.5mm to 3mm, preferably 2mm. The positioning part 414 (positioning post) on the frame 410 has a diameter of less than 0.5mm and a length of approximately 1mm. The positioning mating part 222 (positioning hole) on the isolation frame 42 has a corresponding aperture. The positive electrode 51 has an extension length of 5mm to 10mm and a height of 5mm to 10mm, preferably 7mm. The plating thickness of the positive electrode frame 41 is approximately 0.2μm to 5μm. The negative electrode frame 43 has the same dimensions as the positive electrode frame 41.

[0118] When the edges of two of the aforementioned spliced ​​electrical components 100 are brought close together, the magnetic attractors 2 on the edges magnetically attract and connect the edges of the two spliced ​​electrical components 100. Simultaneously, the positive electrodes 51 on the corresponding edges of the two components come into contact with each other, achieving positive electrode interconnection, and the negative electrodes 52 on the corresponding edges of the two components also come into contact with each other, achieving negative electrode interconnection, thereby establishing a conductive path and meeting the requirement of forming a complete current loop. Since each electrode has three exposed electrode contact surfaces 512a, the two spliced ​​electrical components 100 can be spliced ​​at any angle, that is, the included angle between two adjacent surfaces can be between 0 and 360 degrees, and their corresponding electrodes can effectively contact each other.

[0119] After the modular electrical component 100 is connected to the power supply, the current flows sequentially through the positive electrode 51, the frame 410 of the positive electrode frame 41, the functional component 6, the frame 430 of the negative electrode frame 43, and the negative electrode 52, thus forming a complete current loop, which enables the functional component 6 to work.

[0120] In this embodiment, the power supply frame 161 has two electrical connection terminals 17 and two negative connection terminals 18. The two positive connection terminals 17 are electrically connected to all four positive electrodes 51 through the positive electrode frame 41, and the two negative connection terminals 18 are electrically connected to all four negative electrodes 52 through the negative electrode frame 42. This is equivalent to having two sets of light-emitting devices 162. The multiple light-emitting devices 162 in each set are connected in parallel. After the two sets of light-emitting devices 162 are connected in series, one end is electrically connected to multiple positive electrodes 51, and the other end is electrically connected to multiple negative electrodes 52. Therefore, as long as one side of the spliced ​​electrical component 100 is spliced ​​with the side of another spliced ​​electrical component 100, or a pair of electrodes on one side of it is connected to the power supply, the spliced ​​electrical component 100 is connected to the current loop, and all the light-emitting devices 162 in the spliced ​​electrical component 100 can emit light.

[0121] The modular electrical component 100 of this embodiment can be used as a toy for children to play with, allowing them to assemble various planar or three-dimensional shapes; or it can be used as an educational tool for teaching children, such as teaching architectural knowledge; cultivating children's three-dimensional thinking; displaying illuminated letters and words to teach children letters, words, or mathematical operations; displaying illuminated patterns to teach children knowledge related to the patterns, such as the meaning of signs or knowledge of animals and plants; or it can be used as a festival decoration, modular lighting fixture, modular billboard, etc.

[0122] Functions and effects of Example 1

[0123] According to the electrical connection assembly and the modular electrical component provided in this embodiment, the electrical connection assembly has a positive electrode frame and a negative electrode frame, which are respectively used to contact the positive and negative connection ends of the electrical functional component to achieve electrical connection (i.e., conductive contact). Each of the two electrode frames has a corresponding electrode, thus realizing the electrical connection between the electrical functional component and the electrode, replacing the existing conductive wire and electrical contact structure. This makes the internal electrical connection structure of the modular electrical component simple, easy to manufacture and assemble, thereby improving production efficiency. Simultaneously, the electrode frame structure has a certain structural strength and higher reliability compared to soft conductive wires. Even after prolonged use or exposure to drops, the modular electrical component is less prone to poor contact or wire breakage, enabling long-term stable operation. Furthermore, since the two electrode frames are isolated by an isolation frame, short circuits caused by contact between the two electrode frames can be prevented, improving the reliability of the electrical connection assembly. Furthermore, since the electrode frame has multiple positioning parts and the isolation frame has multiple matching positioning mating parts, the relative positions of the two electrode frames and the isolation frame can be positioned to avoid relative positional offset that would affect the electrical connection, thereby further improving the reliability of the electrical connection assembly.

[0124] In the embodiments, the functional components have light-emitting functions, and the housing is correspondingly transparent or semi-transparent. Since the internal structure can be seen through the housing, the use of an electrode frame also avoids the messy structure of multiple conductive lines affecting the aesthetics of the spliced ​​electrical components.

[0125] In this embodiment, the housing is rectangular and sheet-like, with a pair of positive and negative electrodes on each side. Therefore, each side can be used to connect with other modular electrical components to achieve electrical connection, providing more possibilities for splicing and combination, making the product more interesting.

[0126] Furthermore, two magnetic clasps are embedded on each side of the housing. A pair of positive and negative electrodes are respectively set on both sides of the magnetic clasps, that is, near the corners of the housing, so that there is a large gap between the pair of positive and negative electrodes. By setting the polarity of the magnetic clasps, when the two spliced ​​electrical components are spliced ​​together by magnetic attraction on any two sides, the corresponding magnetic clasps are precisely aligned and generate an attraction force, automatically aligning and connecting the positive and negative electrodes of the two spliced ​​electrical components. That is, physical splicing and circuit conduction are completed simultaneously through magnetic attraction, realizing an intelligent interactive experience of powering on upon splicing, and making the user experience better.

[0127] Furthermore, since each side of the housing is provided with two magnetic accommodating cavities, and each magnetic accommodating component is set in the corresponding magnetic accommodating cavity, and the two magnetic accommodating components on each side are set with complementary polarities, it can ensure that the direction is controllable when magnetically splicing, and also ensure that the electrodes of the two spliced ​​electrical components are in contact after being magnetically combined, making splicing more convenient.

[0128] Furthermore, because the housing edge has electrode engagement notches and electrode engagement holes that match the electrode structure, and the inner surface of the housing has frame fitting grooves that match the frame structure of the electrode frame, the stacked frames can be stably fixed in the housing, and each electrode can be fixed and positioned from multiple directions. This prevents the frames and electrodes from shifting during use, further improving the stability of the electrical connection assembly and the reliability of electrode contact when spliced ​​with other modular electrical components. In addition, because the frame is polygonal and three layers of frames are stacked, and the electrodes are block-shaped, the electrical connection assembly itself also has considerable structural strength. After being engaged with the housing, it can also improve the overall structural strength of the modular electrical components.

[0129] Furthermore, the two electrode frames and the isolation frame are relatively fixed and positioned by the cooperation of the positioning part (positioning post) and the positioning mating part (positioning hole), which can further improve the bonding strength and positioning accuracy between the three-layer frame and better avoid contact between each electrode and the frame of the opposite electrode.

[0130] Furthermore, the isolation frame is provided with two sets of positioning holes, which correspond to multiple positioning posts on the two electrode frames respectively. Therefore, the positioning posts of the two electrode frames are completely separated by the isolation frame and will not contact each other. Since they do not need to share positioning holes, the positioning posts of the two electrode frames can be set relatively long. As long as they are slightly less than the thickness of the isolation frame, they will not contact the electrode frame of the opposite electrode, which is also conducive to improving positioning accuracy.

[0131] Furthermore, the two electrode frames and the isolation frame achieve clamping and fixing of the positive and negative electrodes of the functional components and ensure conductive contact through the engagement of conductive contact parts (strip-shaped protrusions) and contact mating parts (grooves). This makes the installation of functional components very convenient and quick, eliminating the need for additional fasteners or welding to form electrical contacts, thus further improving production and assembly efficiency. Moreover, the housing consists of a base and a cover plate, which can be easily removed. Therefore, the functional components inside the housing can be easily inspected and maintained, or replaced with different functional components, further improving convenience and allowing for expansion or modification of its functionality.

[0132] Furthermore, the electrode is in the shape of a cuboid block, with its three contact surfaces exposed outward from the corresponding electrode engagement notches on the shell, and located further outward relative to the corresponding edge (outer surface) of the shell. Therefore, it is easier to achieve electrode contact between two spliced ​​electrical components. The two spliced ​​electrical components can be spliced ​​at any angle within a large angle range, and their corresponding electrodes can effectively contact each other, thereby achieving a higher degree of splicing freedom. Multiple spliced ​​electrical components can be spliced ​​into various planar and three-dimensional shapes, which improves playability and makes the electrode contact more reliable. In the embodiment, the magnetic splicing pieces can emit light stably when spliced ​​into various shapes.

[0133] Furthermore, the electrode frame is integrally formed, with a non-metallic substrate inside and a conductive plating layer on the surface. This allows for the convenient and rapid manufacture of electrode frames, even those with relatively complex structures. Additionally, the substrate can be made of materials such as plastic, resulting in a lightweight electrode frame that reduces the overall weight of modular electrical components and keeps costs low, making it suitable for mass production.

[0134] Furthermore, the two electrode frames can be plated with conductive metals of different colors, so that the exposed positive and negative electrodes are also different colors, allowing users to easily observe and distinguish the positive and negative electrodes and assemble them correctly. When the functional component is a light-emitting component and the housing has transparency, it also makes the appearance of the spliced ​​electrical components more aesthetically pleasing.

[0135] Furthermore, the electrode frames have an axisymmetric structure. When one of the electrode frames is flipped along its axis of symmetry, the multiple electrodes and multiple clearance notches on the two electrode frames can be distributed in a corresponding complementary manner. Due to this ingenious structural design, the two electrode frames can adopt the same structure. In this way, the positive and negative electrode frames can be manufactured using the same equipment (e.g., the same mold) and manufacturing methods, thereby further improving production efficiency, shortening the production cycle, and reducing product costs.

[0136] Example 2

[0137] This embodiment provides an electrical connection assembly and a splicing electrical component. In this embodiment, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0138] Figure 9 This is a perspective view of the modular electrical components in this embodiment. Figure 10 This is an exploded view of the modular electrical components in this embodiment. Figure 11 This is an exploded view of the electrical connection components and functional components in this embodiment.

[0139] like Figures 9 to 11 As shown, the difference from Embodiment 1 is that the distribution of electrodes is different in this embodiment, and correspondingly, the shell structure is different.

[0140] Specifically, in the splicing electrical component 100 of this embodiment, the housing 1 is also square-shaped, and each side has a pair of electrode engaging portions 13 and two magnetic accommodating cavities. The difference is that the two magnetic accommodating cavities are located closer to the two corners connected to the side, and the pair of electrode engaging portions 13 are located between the two magnetic accommodating cavities of the side, that is, in the middle of the side, and are arranged close to each other. Correspondingly, multiple pairs of positive electrodes 51 and negative electrodes 52 are exposed from the middle of each side of the housing 1.

[0141] In the electrical connection assembly 4, each electrode extends outward from the middle of one side of the electrode frame, but is not located at the exact center of the side. Correspondingly, the clearance notch 415 on the positive electrode frame 41, the clearance notch 423 on the isolation frame 42, and the clearance notch 435 on the negative electrode frame 43 are also located at the middle of the side, corresponding to the position of the electrode.

[0142] In this embodiment, the other structures are the same as in Embodiment 1, so they will not be described again.

[0143] Functions and effects of Example 2

[0144] According to the electrical connection assembly and splicing electrical components provided in this embodiment, similar to embodiment one, since each side of the housing has a pair of exposed electrodes, multiple splicing electrical components can be spliced ​​together at any angle within a certain angle range, and their electrodes can stably contact and conduct with each other.

[0145] Example 3

[0146] This embodiment provides an electrical connection assembly and a splicing electrical component. In this embodiment, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0147] Figure 12 This is an exploded view of the modular electrical components in this embodiment.

[0148] like Figure 12 As shown, the spliced ​​electrical component in this embodiment is a power supply component. Compared with Embodiment 1, the difference lies in the structure and function of the functional component 6, and correspondingly, the structure of the housing 1 is also different.

[0149] In this embodiment, the functional component 6 is installed inside the cavity 3 of the housing 1 and located inside the electrical connection component 4. The functional component 6 includes an energy storage device 61 and a circuit board 62.

[0150] The circuit board 62 is electrically connected to the energy storage device 61. The circuit board 62 is provided with multiple switch buttons 621, function buttons 622 and charging interface 623.

[0151] Pressing the switch button 621 can turn the power on or off, and pressing the function button 622 can control the brightness of the light-emitting device 162. The cover plate 12 has two button clearance holes 125 corresponding to the positions of these two buttons. The switch button 341 and the function button 342 pass through the two button clearance holes 125 respectively, and the upper end of the buttons protrudes outside the cover plate 12.

[0152] The charging interface 623 is used to connect a charging cable to charge the energy storage device 61. In this embodiment, the charging interface 623 is a Type-C standard interface. The cover plate 12 has an interface clearance hole 126 corresponding to the position of the charging interface 623.

[0153] The energy storage device 61 and the circuit board 62 are fixed inside the housing 1. The positive and negative terminals of the circuit board 62 are electrically connected to the positive electrode frame 21A and the negative electrode frame 21B, respectively, forming a power supply circuit. When the switch button 621 is pressed, the circuit board 62 is triggered to conduct, and current flows from the energy storage device 61 to the circuit board 62. The electrical connection component 4 cooperates with the conductive path of the spliced ​​electrical component 100 of Embodiment 1, which is spliced ​​with the spliced ​​electrical component 100 of this embodiment, to drive its light-emitting device to work. When the charging interface 623 is connected to an external plug, it can charge the energy storage device 61.

[0154] In this embodiment, the other structures are the same as in Embodiment 1, so they will not be described again.

[0155] A product set (e.g., a set of magnetic toy pieces) may simultaneously include multiple modular electrical components (functional magnetic pieces) of Embodiment 1 and modular electrical components (power magnetic pieces) of this embodiment. There may be one or more power magnetic pieces, and the ratio of the number of power magnetic pieces to functional magnetic pieces is preferably 1:20 to 1:50, depending on the parameters of the energy storage device 61 and the relationship between the parameters of the power supply frame 161 and the functional electrical components.

[0156] Functions and effects of Example 3

[0157] Based on the electrical connection assembly and splicing electrical components provided in this embodiment, and building upon some of the functions and effects of Embodiment 1, the electrical connection assembly includes an energy storage device and a circuit board. The positive and negative terminals of the circuit board are electrically connected to the positive and negative electrode frames, respectively, thus forming a power supply circuit. This allows the electrical component to power other electrical components. When used as a toy, children do not need to connect the magnetic pieces to an external battery; they can simply assemble the power supply magnetic pieces like other magnetic pieces, making it more convenient to use.

[0158] Furthermore, the circuit board has a switch button, a function button, and a charging interface. The cover plate has corresponding clearance holes to expose these components. Pressing the switch button triggers the circuit board to turn on or off. When on, current flows from the energy storage device to the circuit board, driving the functional devices in the assembled electrical components. Pressing the function button enables the corresponding function, such as switching the brightness of the light-emitting device. When an external plug is connected to the charging interface, the energy storage device can be charged via the circuit board. In other words, the assembled electrical components of this embodiment integrate power supply, charging, and control functions into a single component, achieving continuous power supply and flexible start / stop. Simultaneously, the modular design ensures convenient disassembly and maintenance, improving the system's functional scalability and ease of use.

[0159] Example 4

[0160] This embodiment provides an electrical connection assembly and a splicing electrical component. In this embodiment, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0161] Figure 13 This is a perspective view of the electrical connection components and functional components in this embodiment. Figure 14 This is an exploded view of the electrical connection components and functional components in this embodiment.

[0162] like Figure 13 and Figure 14 As shown, compared with Embodiment 1, the difference lies in that the composition of functional component 6 is different in this embodiment, and correspondingly, the structure of electrical connection component 4 is also slightly different.

[0163] Specifically, in the functional component 6 of this embodiment, the power-conducting frame 161 is a rectangular transparent frame, and a light-emitting device 162 is arranged inside it. In the direction of the surface of the housing 1, the area of ​​the functional component 6 in the plane of the cavity 3 accounts for more than or equal to 80%, so the proportion of the light-emitting area is large, and a better light-emitting effect can be obtained.

[0164] The power supply frame 161 can be engaged inside the isolation frame 42. The positive connection end 17 and the negative connection end 18 are designed with protrusions, both protruding from the same side wall of the power supply frame 161 and spaced apart along the length of that side wall. The isolation frame 42 is U-shaped, a square frame missing one edge, so that after the positive electrode frame 41 and the negative electrode frame 43 are installed, a clearance cavity 300 is left between the two frames. The positive electrode frame 41 has a conductive contact part 412 in the middle of one side, which is a protrusion; the negative conductive frame 43 has a conductive contact part 432 in the middle of one side, which is also a protrusion. The conductive contacts 412 and 432 both extend toward the clearance cavity 300. When the side of the power supply frame 161 is engaged into the clearance cavity, the positive connection end 17 and the negative connection end 18 contact the conductive contacts 412 and 432 respectively.

[0165] Due to manufacturing limitations, the interior of the power supply frame 161 on this side (i.e., the side with the positive connection end 17 and the negative connection end 18) does not have the conditions to accommodate the light-emitting device 162, resulting in this side not emitting light. In order not to affect the aesthetics, the non-light-emitting edge is embedded in the clearance cavity, and the positive electrode frame 41 and the negative electrode frame 43 on both sides are used to shield and hide the non-light-emitting part, the positive connection end, the negative connection end, and the positive contact bump and the negative contact bump of the power supply frame 161, thereby improving the aesthetics of the spliced ​​electrical components.

[0166] Functions and effects of Example 4

[0167] Based on the function and effect of Embodiment 1, the electrical connection assembly and spliced ​​electrical components provided in this embodiment, since the power supply frame adopts a rectangular transparent frame, almost all the space inside the conductive frame and the isolation frame can be used to set up the power supply frame and the light-emitting device. Therefore, a larger light-emitting area can be obtained, so that the spliced ​​electrical components have a better light-emitting effect.

[0168] Furthermore, by using positive and negative electrode frames to conceal the non-light-emitting parts of the power-conducting frame and the positive and negative connection terminals, the overall appearance of the spliced ​​electrical components is aesthetically pleasing.

[0172] like Figure 15 As shown, compared with Embodiment 1, the difference lies in that, in this modified example, the shape of the power supply frame 161 is rectangular, and its size is smaller than that of the isolation frame 42.

The power supply frame 161 is correspondingly provided with two positive connection ends 17 and two negative connection ends 18, each distributed at a corresponding position in the cross structure to ensure the balance of the electrical connection. Specifically, the two positive connection ends 17 are located at the ends of two of the frame sections, and the two negative connection ends 18 are located at the ends of the other two branches.

[0185] The conductive contact portion 412 on the positive electrode frame 41 is located at the middle of two sides of the positive electrode frame 41, and the conductive contact portion 432 on the negative electrode frame 43 is located at the middle of two sides of the negative electrode frame 43. Multiple contact mating portions 421 on the isolation frame 42 are correspondingly located at the middle of each side of the isolation frame 42. The positive connection end 17 and the negative connection end 18 of the power-conducting frame 161 are embedded in corresponding grooves, such that each corner of the power-conducting frame 161 is located at the middle of each side of the electrode frame.

[0227] The power supply frame 161 is rectangular, corresponding to the shape of the housing 1. A positive connection end 17 and a negative connection end 18 extend from the middle of each end along its length.

[0231] Figure 25 This is an exploded view of the structure of the spliced ​​electrical component in this modified example.

[0232] like Figure 25 As shown, the difference from Embodiment 1 is that in this modified example, the shell 1 is in the shape of a pentagonal plate with equal lengths of its five edges.

[0233] The frame 410 of the positive electrode frame 41, the isolation frame 42, and the frame 430 of the negative electrode frame 43 are pentagonal frames that match the housing 1.

[0238] Figure 26 This is an exploded view of the structure of the spliced ​​electrical component in this modified example.

[0239] like Figure 26As shown, the difference from Embodiment 1 is that in this modified example, the shell 1 is in the shape of a hexagonal sheet.

[0240] The frame 410 of the positive electrode frame 41, the isolation frame 42, and the frame 430 of the negative electrode frame 43 are hexagonal frames that match the housing 1.

[0241] The power supply frame 161 is a hexagonal star shape corresponding to the shape of the housing 1.

[0244] This variation is a variation of Embodiment 1. In this variation, the same symbols are assigned to the same constituent elements as in Embodiment 1 and the corresponding descriptions are omitted.

[0245] Figure 27 This is an example diagram of the splicing of multiple electrical components in this variation.

[0246] like Figure 27 As shown, the difference from Embodiment 1 is that this variation illustrates the splicing of various different shaped interlocking electrical components, including the square magnetic chuck of Embodiment 1, the right-angled triangular magnetic chuck of Variation 7, and a relatively larger square magnetic chuck.

[0247] The large square magnetic absorbing sheet has a side length approximately twice that of the square magnetic absorbing sheet in Embodiment 1. Each side of the large square magnetic absorbing sheet has two pairs of positive electrodes 51 and negative electrodes 52. That is, the frame 410 of its positive electrode frame 41 is also square, with two positive electrodes 52 on each side, one near a corner and the other in the middle of the side. The structure of the negative electrode frame 43 is similar to that of the positive electrode frame 41. Similar to Embodiment 1, each pair of positive electrodes 51 and negative electrodes 52 is spaced apart by a magnetic absorbing element 2. The right-angled triangular magnetic absorbing sheet has a right-angled side length approximately equal to that of the square magnetic absorbing sheet in Embodiment 1.

[0248] Since each edge of the housing 1 of the above-mentioned magnetic absorbing sheets is provided with at least one pair of electrodes 5 and magnetic absorbing components 2, magnetic absorbing sheets of different shapes can be freely combined through magnetic adsorption to form diverse forms. At the same time as magnetic splicing, the magnetic position establishes a conductive path through the electrodes 5. When an external power source is connected, the current can trigger the built-in functional components 6 through these electrode paths, thereby realizing the light-emitting function.

The side length of the straight edge of the petal-shaped magnetic chuck is approximately equal to the side length of the hexagonal magnetic chuck. Similar to Variation 12, because the side lengths are approximately equal and the edges have a pair of positive and negative electrodes, these magnetic chucks of different shapes can be freely spliced ​​together.
