Abstract
Description
Technical Field
[0001] This application relates to the field of power adapters, and more particularly to a liquid-proof bracket and adapter. Background Technology
[0002] Potting the power adapter with adhesive can enhance the stability of the internal components, preventing them from loosening or shifting due to external factors such as vibration and impact, and reducing the probability of failure caused by poor component contact. Some high-performance potting compounds have good thermal conductivity, allowing the heat generated by the internal components to be evenly conducted away when the power adapter is working, resulting in a more uniform heat distribution and preventing localized overheating. At the same time, potting provides good electrical insulation, effectively isolating components with different potentials, preventing current leakage and arcing, and ensuring user safety and normal equipment operation.
[0003] However, when potting a power adapter, if the adhesive gets into the adapter's interface, it may form a film on the surface of the metal contacts. If this film is non-conductive, it will directly interrupt the electrical connection between the interface and external devices (such as power cord plugs or the power interfaces of electrical appliances). Even if the adhesive has some conductivity, its uneven distribution or irregular shape after curing may alter the physical and electrical characteristics of the interface. Adhesive entering the interface can also change its mechanical structure; during insertion and removal, the adhesive may cause the interface to become stiff or create obstruction. For interfaces with signal transmission functions, such as those that simultaneously charge and transmit data, the adhesive may damage the original insulation layout. Therefore, there is an urgent need for a device to prevent liquid from entering the interface during power adapter potting. Utility Model Content
