Embodiment 1

[0029] A magnetic attraction type electronic building block construction module shown in FIG. 1 to FIG. 5 comprises a circuit board 2. The circuit board 2 comprises a circuit board body 21. The circuit board body 21 is provided with connecting holes 22 which are specifically two through holes arranged up and down and symmetrically disposed about the circuit board body 21. A spring needle holder 3 is installed on the bottom of the circuit board 2. The spring needle holder 3 comprises a spring female needle holder 31 and a spring male needle holder 32. Specifically, needle holes 33 are formed in the spring female needle holder 31 and the spring male needle holder 32. Spring female needles 36 matched with the needle holes 33 are installed in the needle holes 33 of the spring female needle holder 31. Spring male needles 34 matched with the needle holes 33 are installed in the needle holes 33 of the spring male needle holder 32. The needle holes 33 in two needle holders are horizontally arranged and are at the same level, so as to ensure the stability of electrical connection after connection. Upper ends of the spring female needle holder 31 and the spring male needle holder 32 are fixedly provided with needle holder protrusions 35 matched with the connecting holes 22. The two needle holders are installed on the bottom of the circuit board 2 through the matching between the protrusions 35 and the connecting holes 22. Further, to improve the connection stability, the spring needle holder 3 is welded with the circuit board 2. A bottom plate 4 is installed on the bottom of the spring needle holder 3. The bottom plate 4 comprises a bottom plate body 41. Bottom plate upper protrusions 42 are fixedly installed around the upper surface of the bottom plate body 41, and specifically, fixedly installed at four corners, and preferably, integrally formed. A space formed inside is matched with a structure after combination of the circuit board 2 and the spring needle holder 3, which is convenient for fixedly installing the circuit board 2 and the spring needle holder 3 on the bottom plate 4. Magnet grooves 44 are formed in the upper surfaces of the bottom plate upper protrusions 42. Magnets 45 are installed in the magnet grooves 44. Magnetic attraction is conducted through the matching of the magnets 45, and attention should be paid to the direction of magnetic attraction during installation.
