On May 31, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Philips Technology Co., Ltd. had obtained a patent entitled "a rail socket adapter", with the authorization announcement number of CN221057785U and the application date of September 2023.
The patent abstract shows that the utility model discloses a track socket adapter, which belongs to the field of power socket structure design, comprising a shell, as well as a grounding plug sleeve, a live wire plug sleeve, and a zero wire plug sleeve fixed inside the shell; Install a power socket at the bottom of the shell, which is equipped with a zero wire pin and a live wire pin; The power socket is equipped with vertical perforations for the grounding terminal to pass through. The grounding terminal is a retractable structure that includes a hollow first conductor, a second conductor that can be moved up and down at the bottom of the first conductor, and a spring inside the first conductor that provides downward elasticity for the second conductor. Under the action of the spring, the lower end of the second conductor extends out of the first conductor, and the upper end of the first conductor is fixedly connected to the grounding sleeve. The rail socket adapter in this utility model has stable and reliable grounding conductivity performance through structural optimization, and is easy to assemble, which has good practicality.
