Improved magnetic type electronic bricks system

Abstract

The invention discloses an improved magnetic type electronic bricks system. The improved magnetic type electronic bricks system is provided with a plurality of module bricks provided with output or input connectors and spliced in an attraction mode. Each connector comprises a main plastic body and a plastic back cover detachably fixed to the main plastic body, wherein the main plastic body is provided with a fool-proof structure, and the plastic back cover is provided with at least one cavity internally provided with a magnet or magnetic attraction metal. Each connector is provided with a one-positive and one-negative power source conducting connecting piece and at least one data signal conducting connecting piece. The setting position of the conducting connecting piece shared by the input and output connectors conforms to the mirror symmetry corresponding relation. The improved magnetic type electronic bricks system is suitable for expanding a data signal line, and more functional applications of the electronic bricks system are improved; the placing requirement of magnetic poles is greatly lowered through an attraction mode for plastic back cover magnet installation, the producing and manufacturing cost can be reduced, the abutting plane of an insulator body cannot be occupied, expansion of more conducting connecting pieces is facilitated, and the magnets are protected extremely well; the space can be fully utilized due to placement of the conducting connecting pieces, and expansion of more conducting connecting pieces is facilitated.

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 module 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
