Description

Technical Field

[0001] The utility model relates to the technical field of circuit board assembly, in particular to a circuit board kit which can be assembled quickly. Background Art

[0002] A circuit board, also known as a printed circuit board, is a support that connects electronic components and circuits together. It is used to realize the layout design of complex circuits and the transmission of electrical signals in electrical and electronic equipment. It is usually made of glass fiber as the base material and processed by copper coating, gold plating, etching and other processes. Circuit board kits usually include various types and functions of electronic components, such as sensors, capacitors, interfaces and terminal blocks.

[0003] The transformer is one of the components of the circuit board assembly. The main function of the transformer is to ensure the safe and efficient transmission of electrical energy between different circuit parts. During the installation of the circuit board, the transformer is usually installed and fixed to the circuit board by bolts. The connection method is both stable and reliable, which helps to reduce the impact of electrical interference and mechanical vibration on the performance of the transformer. However, when the transformer needs to be replaced due to long-term use or external factors, the bolts connecting the transformer to the circuit board are often small in size and compact in position, making the disassembly and assembly process quite inconvenient. The disassembly and assembly process also requires the use of small tools such as screwdrivers and wrenches. In such an operating environment, it is very easy for the tool to slip or touch by mistake, which in turn causes damage to other circuit board assemblies around it, and even affects the stability and safety of the entire electronic system. In view of this, we propose a circuit board assembly that can be assembled quickly. Utility Model Content

[0027] In this embodiment, the fixing seat 14 and the connecting seat 19 are integrally formed, and the angle between the fixing seat 14 and the connecting seat 19 is 90°. The integrally formed fixing seat 14 and the connecting seat 19 have better connection strength, ensuring the fixing effect of the fixing seat 14 and the connecting seat 19 on the transformer 11, and the vertical connecting seat 19 can better support and fix the transformer 11.

[0028] In this embodiment, the overall shape of the connecting seat 19 is U-shaped, and the size of the slide groove 190 is adapted to the size of the slider 12. This design is conducive to limiting the slider 12 through the slide groove 190, ensuring the installation stability of the transformer 11.

[0029] In this embodiment, a pull plate 172 is fixed to one end of the slide plate 17 away from the plug block 171, and the end of the pull plate 172 extends out of the fixing seat 14. By pulling the pull plate 172, the slide plate 17 and the plug block 171 can be driven to move horizontally, thereby facilitating the adjustment of the position of the plug block 171.

[0030] In this embodiment, ear plates 18 are fixed to both the front and rear side walls of the fixing seat 14, and fixing holes are provided on the ear plates 18. The fixing holes are penetrated by connecting bolts 180 that are threadedly connected to the plate body 1. This design ensures the reliability and stability of the connection between the fixing seat 14 and the plate body 1, and thus helps to ensure the installation stability of the transformer 11.

[0031] In this embodiment, a plurality of positioning posts 13 are fixed to the bottom of the transformer 11, a plurality of positioning holes are provided at the top rear side of the plate body 1, and the positioning posts 13 are plugged into the positioning holes. The arrangement of the positioning posts 13 and the positioning holes increases the installation stability and reliability of the transformer 11.

[0033] It can be understood that the slider 12, the fixing seat 14 and the connecting seat 19 in this embodiment are made of plastic material, and the slider 12 is tightly bonded to the outer wall of the transformer 11. The slider 12, the fixing seat 14 and the connecting seat 19 made of plastic material have the advantage of insulation, avoiding the occurrence of leakage and the like, and ensuring the insulation effect of the transformer 11 after installation.

[0034] When assembling the transformer 11, the user first aligns the sliders 12 on both sides with the slide grooves 190 on both sides and inserts them, and presses the transformer 11 downward. Then, the user pulls the pull plates 172 to both sides so that the slide plate 17 moves horizontally along the two guide rods 15. The spring 16 is compressed by the slide plate 17. At this time, the slide plate 17 drives the plug 171 to retract into the cavity. At the same time, the user presses the transformer 11 downward so that the slider 12 is completely inserted into the slide groove 190. Next, the user releases the pull plates 172 on both sides. Under the elastic action of the spring 16, the slide plate 17 drives the plug 171 to reset. The plug 171 is inserted into the slot 120, and the transformer 11 is fixed to the connecting seats 19 on both sides. The transformer 11 is assembled.
