Description

Technical Field

[0001] The utility model belongs to the technical field of transformer packaging, and in particular relates to a transformer packaging mold. Background Art

[0002] A transformer is an electrical device used to change the voltage of alternating current. It consists of two or more coils (called primary coils and secondary coils), usually connected by a magnetic core. When alternating current passes through the primary coil of the transformer, an alternating magnetic field is generated in the core, which induces an electromotive force in the secondary coil. Depending on the ratio of the number of turns in the coil, the transformer can step up (step-up transformer) or step down (step-down transformer) the voltage. Transformers are widely used in power transmission, electronic equipment and industrial purposes. The packaging molds of transformers are usually plastic molds made of thermoplastic or thermosetting materials. These molds are used to encapsulate and protect the coils and internal components of the transformer to prevent damage from the external environment and provide electrical insulation. These molds usually need to have good heat resistance, insulation and mechanical strength to ensure the safe and reliable operation of the transformer. Choosing the right packaging mold is very important for the performance and life of the transformer.

[0003] The encapsulation mold can encapsulate the coil and internal components of the transformer to protect them. This helps prevent the external environment from eroding and damaging the internal components, while providing electrical insulation and mechanical protection. Through the encapsulation mold, the direct contact of the internal components can be effectively isolated and prevented, reducing the risk of short circuit or electric shock, and improving the safety of the transformer. The encapsulation mold can fix and stabilize the position of the internal components, reduce the impact of vibration and external shock on it, thereby improving the stability and durability of the transformer. The encapsulation mold can also enhance the appearance of the transformer and make it more beautiful. At the same time, the encapsulation mold can also prevent dust and impurities from entering the interior and keep the transformer clean. In short, the encapsulation mold of the transformer plays a vital role in the performance and reliability of the transformer by protecting the internal components, improving safety, stability and durability, as well as aesthetics and dustproof functions. The problem with the above technology is that during the use of the encapsulation mold, the molds on both sides need to be attached and connected and fixed through multiple connectors and fixings. Therefore, it will take a long time and energy for the user to assemble and disassemble the encapsulation mold, thereby reducing the assembly effect of the encapsulation mold, and it is not convenient for the user to use.
