Description

Technical Field

[0001] The utility model relates to the technical field of electronic building blocks, and particularly to a connection structure of electronic building blocks. Background Art

[0002] Electronic building blocks are to fix wires and various electronic components on a circuit board to form building block components, and then assemble various components into a circuit combination on the installation base plate configured with the product like building blocks. Such electronic building blocks are commonly connected by magnetic adsorption. For example, a magnetic electronic building block disclosed in Chinese Patent CN206121169U. The design of the copper cap, spherical magnetic bead and metal conduction sheet makes the copper cap a magnetic conduction part on the one hand. And because the spherical magnetic bead can conveniently adjust its positional relationship with the copper cap by rolling, the magnetic connection between two electronic building blocks is more stable. On the other hand, since the copper cap is in full contact with and pressed against the metal conduction sheet, the copper cap also undertakes part of the circuit conduction. However, in the actual use process of the magnetic electronic building block, since both the base body and the copper cap are hard parts, the limitation on the connection position is large, and the positions of the electronic building blocks cannot be placed randomly, resulting in a poor use experience. Moreover, magnetic blocks and metal terminals are arranged on the connection ends of each electronic building block base body, which will greatly increase the production cost of the electronic building blocks and is not easy to implement and promote. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a connection structure of electronic building blocks to solve the problems of large limitation on the connection position and high production cost of the existing connection structure of electronic building blocks mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides a connection structure of electronic building blocks, including an electronic base body and a wire base body. The electronic base body includes a shell, and electronic components and a conductive part installed on the shell. The electronic components are electrically connected to the conductive part. The conductive part includes a fixed leg and a conductive contact fixed integrally. The fixed leg is inserted and fixed in the shell, and the conductive contact is exposed on the shell. The wire base body includes a flexible wire and a connector. The connector includes a protective shell, a conductive sheet and a magnetic block. The protective shell is fixed at the end of the flexible wire. The conductive sheet is electrically connected to the flexible wire and exposed on the protective shell. The magnetic block and the conductive sheet are superposed and fixed in the inner cavity of the protective shell. The magnetic block is used to adsorb the conductive sheet on the conductive contact, so that the conductive part and the conductive sheet can be in conductive contact.

[0005] As a preferred solution, the conductive contact protrudes on the shell, and a limiting hole is opened in the side wall of the inner cavity at a position facing the conductive sheet, and the conductive contact can be adaptively connected in the limiting hole.

[0006] As a preferred solution, the flexible wire includes a wire body and a conduction piece that are electrically connected. One conduction piece is fixedly arranged at each end of the wire body. The conduction piece is clamped between the conductive piece and the magnetic block, and the three are stacked and fixed in the inner cavity.

[0007] As a preferred solution, the protective housing is made of an insulating material, and the conductive member, the conductive piece, and the flexible wire are all made of conductive metal materials.

[0008] As a preferred solution, the conductive member is one of a rivet, a thumbtack, or a screw, and the magnetic block is one of a ferrite magnet or a neodymium iron boron magnet.

[0009] As a preferred solution, the protective housing includes a first housing and a second housing that are fixedly connected. An inner cavity is formed between the first housing and the second housing. A wire passing hole is provided at the connection between the first housing and the second housing, and the flexible wire is passed through the wire passing hole.

[0010] As a preferred solution, the inner cavity includes a chamber for fixedly installing the conductive piece and the magnetic block, and the chamber is a cylindrical cavity structure.

[0012] As a preferred solution, a second circular groove is provided inside the second housing at a position corresponding to the chamber. The conductive piece is adaptively connected in the second circular groove, and a limiting hole is provided in the bottom wall of the second circular groove.

[0013] As a preferred solution, the first housing and the second housing are connected and fixed by a plurality of connectable and cooperable connecting columns and connecting grooves, and the first housing and the second housing are also fixed by ultrasonic welding.

The wire base body is composed of a flexible wire and a wire connector. The conductive sheet of the wire connector is electrically connected to the flexible wire, and the conductive sheet and the magnetic block are superposed and fixed in the inner cavity of the protective housing. The wire base body can adsorb the conductive sheet on the conductive contact through the magnet, so that the conductive member and the conductive sheet can be in conductive contact, so that the electronic components on two electronic base bodies can be conductively connected through the wire base body. Since the end of the flexible wire can extend to any direction and position, the placement position of the electronic base body is less restricted, and it has the advantage of convenient use.

[0027] Please refer to Figures 1 to 5 , this embodiment provides a connection structure for electronic building blocks, including an electronic base body 100 and a wire base body 200. Among them, the electronic base body 100 includes a housing 110, as well as electronic components 120 and conductive members 130 installed on the housing 110. Four fixing holes 111 are formed on the outer wall of the housing 110, and a conductive member 130 is fixedly installed corresponding to each fixing hole 111. In other embodiments of the present utility model, the number of the fixing holes 111 can be adjusted to two or more than three, etc.

[0028] In this embodiment, the electronic component 120 is a light-emitting diode, and the electronic component 120 is electrically connected to the conductive member 130. For example, the electronic component 120 can be connected to the fixing leg or conductive contact of the conductive member 130 through a wire. The conductive member 130 includes a fixing leg 131 and a conductive contact 132 that are integrally fixed. Among them, the fixing leg 131 is inserted and fixed into the fixing hole 111 so that the conductive member 130 can be fixedly installed on the housing 110. The conductive contact 132 is exposed on the housing 110 and is used for electrically conductive contact with the wire base body 200, so that the electronic component 120 can be electrically connected to the electronic component 120 of another electronic base body 100 through the wire base body 200.

[0029] It can be understood that the conductive member 130 is made of a conductive metal material, such as stainless steel, iron, copper, etc. Specifically, the conductive member 130 provided in this embodiment is a stainless steel semi-hollow rivet, where the rivet leg of the rivet becomes the fixing leg 131, and the rivet cap of the rivet becomes the conductive contact 132. At this time, the conductive contact 132 protrudes on the housing 110. Since the procurement cost of the stainless steel semi-hollow rivet is relatively low and it can be quickly installed on the housing 110, the installation efficiency of the conductive member 130 on the housing 110 can be effectively improved, and at the same time, the production cost can be reduced. At the same time, the setting of the above-mentioned protruding conductive contact 132 enables the conductive contact 132 to be adapted to be connected in the groove cavity of the wire base body 200. After the two are adapted and connected, the wire base body 200 cannot be pushed to move on the housing 110, which can prevent the situation of disconnection caused by misalignment of the two under force, making the connection between the two more firm and reliable.

[0030] In other embodiments of the present utility model, the electronic component 120 can also be set as other electronic components, such as batteries, diodes, triodes, resistors, inductors, switches, inductive switches, knob switches, speakers, buzzers, transistors, lamps, fans, flying saucers, microphones, displays, motors, radio equipment, integrated circuits, etc. The electronic components 120 on multiple electronic substrates 100 can be partially different or completely different. Then, through the wire substrate 200, multiple electronic substrates 100 with different electronic components 120 can be electrically connected into a closed functional circuit, such as a lighting circuit, etc. The conductive member 130 can be selected as other replacements with the structure of the fixed foot 131 and the conductive contact 132, such as metal drawing nails or metal screws, etc. The conductive contact 132 can be adjusted so that its end face is in the same plane as the outer surface of the housing 110, or its end face is recessed on the outer surface of the housing 110.

[0031] The wire substrate 200 includes a flexible wire 210 and a wire connector 220. In this embodiment, the flexible wire 210 has two ends, and a wire connector 220 is fixedly arranged on each end. Specifically, each wire connector 220 includes a protective shell 221, a conductive sheet 222, and a magnetic block 223. Among them, the protective shell 221 is fixed on the end of the flexible wire 210, the conductive sheet 222 is electrically connected to the flexible wire 210, and the magnetic block 223 and the conductive sheet 222 are stacked and fixed in the inner cavity of the protective shell 221. It can be understood that the conductive sheet 222 is exposed on the protective shell 221, and the magnetic block 223 is used to adsorb the conductive sheet 222 on the conductive contact 132, so that the conductive member 130 and the conductive sheet 222 can be in conductive contact. In other embodiments of the present utility model, the flexible wire 210 can be adjusted to a structure with three or more than four ends. At this time, a wire connector 220 is also fixedly arranged on each end.

[0032] In this embodiment, the flexible wire 210 includes a wire main body 211 and a conduction sheet 212 that are electrically connected. A conduction sheet 212 is fixedly arranged on each end of the wire main body 211. The conduction sheet 212 is clamped between the conductive sheet 222 and the magnetic block 223, and the three are stacked and fixed in the inner cavity. It can be understood that the wire main body 211 is electrically connected to the conductive sheet 222 through the conduction sheet 212. In other embodiments of the present utility model, the flexible wire 210 can only include the wire main body 211. At this time, the conductive sheet 222 is directly welded and fixed on the end of the wire main body 211.

[0033] It can be understood that the protective housing 221 is made of an insulating material, such as a plastic material, a rubber material, etc. The conductive sheet 222 and the conduction sheet 212 are both made of a conductive metal material, such as stainless steel, iron, copper, etc. In this embodiment, the magnetic block 223 uses a ferrite magnet with a relatively low cost. In order to maximize the magnetic attraction ability of the magnetic block 223 while reducing the production cost, the conductive sheet 222 is selected as a stainless steel sheet, and the conduction sheet 212 is selected as an iron sheet. In other embodiments of the present utility model, the magnetic block 223 can be selected as a neodymium iron boron magnet. Similarly, the conductive sheet 222 can be adjusted to a copper sheet or an iron sheet, etc., and the conduction sheet 212 can be adjusted to a stainless steel sheet or a copper sheet, etc.

[0034] It can be understood that the protective housing 221 includes a first housing 2211 and a second housing 2212 which are fixedly connected. An inner cavity is formed between the first housing 2211 and the second housing 2212. The inner cavity includes a chamber 2210 for fixedly installing the conductive sheet 222, the magnetic block 223 and the conduction sheet 212. In this embodiment, the chamber 2210 is a cylindrical cavity structure. A first circular groove 2213 is provided inside the first housing 2211 at a position corresponding to the chamber 2210. A plurality of wedge-shaped prisms 2214 are arranged at intervals on the inner wall of the first circular groove 2213. The magnetic block 223 is clamped and fixed between the plurality of wedge-shaped prisms 2214. A second circular groove 2215 is provided inside the second housing 2212 at a position corresponding to the chamber 2210. The conductive sheet 222 is adaptively connected in the second circular groove 2215, and a limiting hole 2216 is opened on the bottom wall of the second circular groove 2215. The limiting hole 2216 is opened at a position corresponding to the conductive sheet 222, and the shape of the limiting hole 2216 is adapted to the conductive contact point 132, so that the conductive sheet 222 can be exposed on the protective housing 221 through the limiting hole 2216, and the protective housing 221 can be adaptively connected to the conductive contact point 132 through the limiting hole 2216, so that the two can be fixed by magnetic attraction and concave-convex fitting at the same time, thereby making the connection more firm and reliable.

[0035] In other embodiments of the present utility model, the chamber 2210 can be adjusted to other three-dimensional cavity structures, such as a square cavity structure, a spherical cavity structure, a rectangular cavity structure, etc. At this time, a groove having the same shape as the chamber 2210 is provided at the position of the first outer shell 2211 corresponding to the chamber 2210, and a groove having the same shape as the chamber 2210 is also provided at the position of the second outer shell 2212 corresponding to the chamber 2210. The two grooves between the first outer shell 2211 and the second outer shell 2212 communicate to form the chamber 2210. If the end face of the conductive contact 132 is in the same plane as the outer surface of the housing 110 or is recessed on the outer surface of the housing 110, the conductive sheet 222 can be clamped and fixed on the surface of the limiting hole 2216 or at least partially protrude outside the limiting hole 2216, so that when the adapter 220 is magnetically attracted to the conductive member 130, the conductive sheet 222 can conductively contact the conductive contact 132.

[0036] It can be understood that a wire passing hole 2217 is provided at the connection between the first outer shell 2211 and the second outer shell 2212. A wire main body 211 is passed through the wire passing hole 2217. The size of the wire passing hole 2217 is smaller than the size of the conduction sheet 212, which can prevent the adapter 220 from detaching from the flexible wire 210, and at the same time facilitate the covering and fixing of the first outer shell 2211 and the second outer shell 2212 on the flexible wire 210.

[0037] In this embodiment, the first outer shell 2211 and the second outer shell 2212 are fixedly connected by a plurality of connecting posts 2218 and connecting grooves 2219 that can be inserted and matched. The connecting posts 2218 and the connecting grooves 2219 are separately provided on the opposite side surfaces of the first outer shell 2211 and the second outer shell 2212. The purpose of fixedly connecting the first outer shell 2211 and the second outer shell 2212 can be achieved by the insertion and matching of the connecting posts 2218 and the connecting grooves 2219. The first outer shell 2211 and the second outer shell 2212 are also fixed by ultrasonic welding to further fix the first outer shell 2211 and the second outer shell 2212. In other embodiments of the present utility model, the first outer shell 2211 and the second outer shell 2212 can also be fixedly connected by other fixing methods, such as glue connection, screw connection, snap connection, etc.

[0038] It should be noted that since the end of the flexible wire 210 can extend in any direction and position, the connection structure of the electronic building block provided in this embodiment has less restriction on the placement position of the electronic substrate 100 and has the advantage of convenient use. At the same time, the connection structure only sets magnetic blocks in the conductive joints 220 of the wire substrate 200, and adopts a structure in which the flexible wire is electrically connected to the conductive sheet and then the conductive sheet and the magnetic block are superposed and fixed on the protective housing, which can save the consumption of relatively expensive magnet materials and conductive metal materials, ensure the normal realization of the magnetic adsorption and electrical conduction functions, and is conducive to reducing the production cost of the electronic building block, making the electronic building block easy to implement and promote.

[0039] For clarity, certain features described in the individual embodiments of the present invention may be combined and used in a single embodiment. Moreover, the various features of the present invention described in a single embodiment may also be used alone or in any suitable form in sub-combinations.
