Abstract
The invention provides a socket and a connector assembly. The socket comprises a socket insulator and jack contact members which are arranged on the socket insulator. The jack contact members are provided with jacks. The jack contact members are provided with through channels enabling the jacks and the external part of the jack contact members to be communicated. The through channels are internally provided with drainage channels in a penetrating way, and the drainage channels are matched with the jack contact members in an insulating way and used for draining water in the jacks in the plugging process. The drainage channels are provided with channel internal end openings which are communicated with the jacks. The periphery of the channel internal end openings is provided with drainage channel sealed matching surfaces. When the plugging ends of pin contact members stretch into the jacks, water in the jacks is directly drained out of the socket via the drainage channels without bringing plugging resistance to the plugging ends of pins. When the pin contact members are unplugged out of the jacks of the jack contact members, water can reversely flow into the jacks of the jack contact members from the external part of the socket via the drainage channels so that pressure of the left and right ends of the pin contact members is enabled to be balanced and thus plugging is relatively laborsaving.
