An improved magnetic suction electronic building block system

Abstract

The invention discloses an improved magnetic suction electronic building block system, which has a plurality of modular building blocks provided with output or input connectors that can be adsorbed and joined together. The connectors include a plastic body and a detachable and fixed plastic Back cover, the plastic body is provided with a fool-proof structure; the plastic back cover is provided with at least one cavity, and a magnet or magnetic metal is built in the cavity; a positive and a negative power supply conductive connector and at least one data signal are provided on the connector As for the conductive connectors, the positions of the conductive connectors shared by the input and output connectors are in a corresponding relationship of mirror image symmetry. This solution is suitable for the extended use of data signal lines and improves the use of more functions of the electronic building block system; the adsorption mode of the magnet installation on the plastic back cover greatly reduces the placement requirements of the magnetic poles, which is conducive to the reduction of manufacturing costs and does not occupy The butt surface of the insulating body is conducive to the expansion of more conductive connectors, and it also protects the magnet very well; the placement of the conductive connectors can also make full use of the space, which is conducive to the expansion of more conductive connectors.

Description

technical field [0001] The invention relates to an electronic building block, in particular to a magnetic suction electronic building block system applied to teaching experiments and electronic building block toys. Background technique [0002] As known, the electronic building block system traditionally used for teaching experiments or electronic building block toys generally includes a complete circuit board and various functional devices. The circuit board is preset with designated circuits and mounting holes. When in use, the The required functional devices are built on the circuit substrate to achieve specific functions. However, ordinary circuit substrates or functional devices are inseparable as a whole. Such products are not limited to a few single functions and have low flexibility. For users who like to disassemble or assemble toys by hand, they cannot understand the functions of the product. The structure and function of the modules are not interesting. [0003]...

AI Technical Summary

Problems solved by technology

[0005] 1. It limits the lines on the circuit board and the connector to 3 lines, which limits the extended use of data signal lines and limits the use of more functions of the electronic building block system;

[0006] 2. There are practical problems about the setting of magnets

First of all, the design of multi-magnets has relatively high requirements for the placement of magnetic poles, which is not conducive to the reduction of manufacturing costs, and directly occupies too many butt joint surfaces of the insulating body, which is not conducive to the expansion of more conductive connectors; more importantly, , the design of the magnet is directly exposed on the docking surface. This design does not protect the magnet in place (at present, most of the magnets are manufactured using powder pressing technology, and the hardness is very low). The magnet is directly outside, and after a long time of hand contact And the surface of the magnet will be oxidized, the magnetic block is easy to crack, and magnetic debris will appear, which will lead to the gradual failure of the magnet, reduce the magnetic attraction force or even damage the magnet

[0007] 3. It limits the design of the conductive connectors to be "set side by side in the insulating body". This limitation can realize its function, but the side-by-side arrangement requires high space requirements, which seriously restricts the expansion of more conductive connectors. , it is not easy to process during manufacture, and the cost is relatively high
