Description

connector assembly

technical field

Embodiments relate to a connector assembly for a terminal device that can be simply configured to be watertight and have a reduced overall height.

Background technique

In general, a mobile communication terminal device includes a voice call function, a video call function, an information input/output (I/O) function, and a data storage function. With the recent diversification of functions, various contents can be accessed through mobile communication terminal devices. Therefore, the mobile communication terminal device may also include a storage medium function to realize storage of personal information or credit payment processing, and other complex functions to capture photos or videos, play back music or video files, play games, and receive broadcasts. Such functions are provided comprehensively to realize a multimedia device.

When many additional functions are provided in the mobile communication terminal device, the connector can be used for data I/O and connection with peripheral devices. The connector may include an I/O port to interface with a peripheral device, or a Universal Serial Bus (USB) port to enable a user to transfer data of a mobile communication terminal device when necessary. Peripheral devices may include, for example, headphones, remote controls, and televisions (TVs).

Existing connectors include a sealing member for a watertight effect. Specifically, a sealing member formed using an elastic material such as rubber is provided between the connectors. When the connectors are coupled to each other, the sealing member is deformed and compressed between the connectors, thereby maintaining the watertightness and sealing performance of the connector coupling portion. However, in existing connectors, a gap is formed between the sealing member and the inner surface of the connector, which reduces the watertight effect of the connector.
