Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a metal plug pin for a socket. Background Art

[0002] Most common sockets need to be manually turned on and off, or need to be connected to a control line to achieve the purpose of remote control. With the development of Internet technology, people hope to have a socket that can be remotely controlled through the network, and does not need to be connected to a control line, which is more convenient to install and use. In order to solve the above problems, WIFI smart sockets came into being. WIFI smart sockets are a kind of socket that uses the existing WIFI network in the home to allow your smartphone or tablet to turn on or off the specified electrical appliances through App operation under the condition of networking. The three-phase pin structure used in the current smart sockets uses a single solder point to weld and connect to the PCB board. However, when welding the pins one by one, this structure cannot be placed firmly on the PCB board, and it needs to be manually positioned and stabilized. In addition, the pins of this single solder point structure are easy to lift the PCB board pad during the plug-in and pull-out process of the pins on the PCB board, causing the pins to fall off, affecting the welding efficiency and quality, as well as the qualified rate of product production.
