Abstract
Description
Technical Field
[0001] This utility model relates to the field of power socket technology, specifically to a power socket structure that improves connection stability and safety by optimizing the internal metal sheet welding process. Background Technology
[0002] In existing power socket manufacturing processes (such as power strips and adapters), the soldering quality between the internal live and neutral wires (L / N poles) and the copper strip directly affects the product's safety and reliability. Currently, the industry commonly uses the following process: arranging multiple metal plates (corresponding to different sockets) adjacent to each other and directly soldering them to the wires. However, this process is prone to poor soldering, leading to safety hazards: unavoidable gaps exist between adjacent metal plates, making it difficult for the solder to fill evenly, easily resulting in incomplete soldering or missed solder joints. Poor soldering can easily cause socket contact failure, increased local resistance, and consequently, arcing, overheating, or even fire.
[0003] The core reason is that the direct many-to-one welding process between the metal sheet and the wire cannot guarantee the uniformity and long-term stability of the solder joints. Therefore, there is an urgent need for a power socket with a new welding structure to solve the safety hazards and efficiency bottlenecks in the existing technology. Utility Model Content
