Description

Combined circuit board, combined circuit kit and component connector

[0001] The present invention belongs to the field of electronic circuits, and more particularly to a combined circuit board, a combined circuit package, and a component connector.

Background technique

[0002] With the continuous development of science and technology, various electronic products and intelligent devices have become indispensable items in people's lives and work. Under the background of national and social encouragement of innovation and entrepreneurship, high-tech industry has become one of the most important directions for people. As the basis of various high-tech and intelligent control systems, electronic circuits have always been the hotspot of people's research. It is precisely because of such an innovative and in-depth atmosphere that people's interest and enthusiasm for the study, research and development of electronic circuits are constantly rising, and this is the basis for talent cultivation. Today, as the world is striving for the commanding heights of science and technology, intensifying efforts to train talents with technological innovation capabilities has become a problem that the state and society generally attach importance to.

[0003] Therefore, how to adapt and guide people, especially young people's curiosity, interest and hobbies in the science and technology contained in electronic products has become a top priority. However, the traditional circuit boards used in teaching, testing, and experimenting, such as the universal board, have many drawbacks. They solder the electronic components to the pads of the universal board or the breadboard by soldering. After the soldering is completed, the components are in the universal board. Or the position on the breadboard is fixed, and the problem of soldering and false soldering is easy to occur. It is not easy to check it out. At the same time, because the position is fixed, it is often necessary to spend a lot of energy if the welding is wrong. Soldering and re-soldering, if you accidentally burn components or the universal board, the breadboard itself, it may seriously harm the person; and this often requires a replacement of a universal board or breadboard, which not only consumes a lot of energy but also costs a lot.曰^Q

[0004] With the pursuit of low-carbon, environmental protection, energy-saving and other environmental awareness, on the basis of the universal board, people have issued a breadboard. 1 is a structural view of a breadboard of the prior art, the breadboard including a bottom plate, a wiring panel having a wiring hole, and a metal for connecting circuit components is inserted under each of the column wiring holes. a reed, wherein the wiring panel is fixedly connected to the bottom plate, and the metal reed is fixedly inserted into the predetermined slot; the wiring hole and the slot for mounting the metal reed are integrally formed in a predetermined manner. On the wiring panel and the bottom plate, the structure is fixed, can not be adjusted and changed, and the metal reed is pre-installed. The primary circuit design often does not need to be used all at all, which will cause a lot of waste, and the cost of the mold is also increased. Compared with the universal board, it can be re-used, low-carbon and environmentally friendly because it does not need to be welded or a small number of joints. However, due to the dense wiring holes, the wiring is prone to errors, the connection is unstable, and the problem is difficult to check and find. If the method is fixed, if the bottom plate or the wiring panel is damaged, it cannot be partially replaced, it is easy to be scrapped, the cost is high, and the difficulty of popularization is relatively large.

[0005] As shown in FIG. 2 and FIG. 3, the existing breadboard has a fixed structure. In the process of the user's circuit arrangement, according to the general circuit layout logic, the circuit boards are pre-planned into various The module area is connected to the circuit, but in the actual connection, in the case of poor consideration, complicated circuit, limited board size, and increased circuit module, etc., since the panel connecting the circuit components is fixed, it is often impossible to Modifications are made on the basis of not disturbing the existing arrangement. As a result, the arrangement of the entire circuit is often disordered, and the arrangement of the original circuit diagram cannot be visually presented from the circuit board, and the difficulty of circuit viewing and error correction is greatly increased.

[0006] Therefore, in the existing circuit board, the substrate and the device for connecting the circuit components are fixed structures, and the modules on the circuit board or the circuit board are not easily adjusted and replaced, so that the component layout on the circuit board cannot visually present the circuit diagram. The components in the arrangement are not reusable, have a low service life and are costly.
