 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building block structure, and more particularly to a modular building block utilizing contact conduction. Background technique

 With the development of the electronics industry, the existing educational toys such as building blocks have spawned a variety of new building blocks. For example, a circuit board, an LED lamp, a sounder, and the like are installed in the original building block, so that the building block can be electrically connected to emit light, music, and the like, and has the effect of enhancing the fun of the building block.

 Among them, the existing electrical connection building block, such as the Chinese utility model patent of the patent number ZL 201020693329.8, has a power receiving column inserted on the circuit board, and the power receiving column is mainly provided with a positive power receiving component and a negative power receiving component. The positive and negative electrical components each have a metal lead, and each metal lead is soldered to the circuit board and connected to the electronic component through the circuit board. However, the existing illuminating blocks are provided with a positive electrode and a negative electrode at the same time in the fixed column, so that the assembled components of the fixed column are numerous and the structure is complicated. At the same time, the positive and negative electrical components need to be soldered to the circuit board by the steps of electric welding, which has many disadvantages such as labor and environmental pollution in the manufacturing process.

 Further, since the positive electrode and the negative electrode are installed in the same wedge hole, once a metal foreign object falls into the wedge hole, or the insertion wedge portion is deformed by being pressed, the two easily come into contact to form an electrical connection, thereby causing a short circuit of the circuit. Summary of the invention

 In order to solve the problems of many existing conductive building blocks, complicated structure, spot welding of positive and negative electrical components, and danger of short circuit, the main object of the present invention is to provide a small component, simple structure, and no need for positive and negative electrical components. Spot welding is a modular contact conductive building block that improves safety.

 In order to achieve the above object, the present invention provides a modular contact type conductive building block, comprising: a hollow building block having a top surface projecting upwardly formed with at least one pair of wedge portions, and a bottom surface forming a communication to the inside. Opening, the wedge portion is provided with a wedge hole connected to the inside;

At least one pair of fixing posts disposed in the wedge holes, comprising an insulating member and a conductive member, the insulating A mounting hole is formed in the inner portion of the device, and a protruding groove is formed on the side surface to communicate with the mounting hole. The conductive member is disposed in the mounting hole of the insulating member, and forms an insertion hole through the mounting hole at the upper end. a contact electrode extending laterally from the side surface and protruding from the contact electrode of the protruding groove, and a series of electrodes protruding downwardly from the lower end;

 a circuit board disposed in the building block and sleeved on the fixing post, comprising a positive circuit, a negative circuit and a functional unit, the positive circuit contacting the contact electrode of one of the fixed columns The fixed column is defined as a positive electrode fixed column, and the negative electrode circuit is in contact with a contact electrode of another fixed column of each pair of fixed columns, and the fixed column is defined as a negative electrode fixed column, and the functional unit is electrically connected to the positive electrode circuit. And the negative circuit;

 A base disposed in the building block, formed with at least one pair of perforations through which the fixing post passes. Compared with the prior art, the beneficial effects of the present invention are as follows:

 In the modular contact type conductive building block of the present invention, the structure of each fixing post is the same, and the inner conductive member and the insulating member have a simple structure and are easy to assemble. Therefore, the complicated structural design in the past can be effectively simplified, and the effect of greatly reducing the production cost can be achieved. And the top of the fixing post abuts against the building block, the contact electrode of the fixing post abuts against the circuit board, and the circuit board abuts against the base, and the base is fixedly disposed in the building block, so that the conductive member can tightly contact the circuit board. Instead of spot welding, the advantages of environmental protection and labor saving are achieved.

 Furthermore, since the positive and negative electrodes of the fixed post mainly depend on whether the contact electrode of the internal conductive member is in contact with the positive circuit or the negative circuit on the circuit board. Therefore, after the assembly of the fixed column of the building block, it can be clearly divided into a positive fixed column or a negative fixed column, even if a metal foreign object falls into the wedge hole, or the wedge portion is deformed by being squeezed, it will not cause The short circuit of the circuit ensures high safety of the building blocks.
