Description

Electrical connector socket with limit function

technical field

The utility model relates to an electrical connector socket, in particular to an electrical connector socket which provides limit insertion of different transmission interfaces.

Background technique

At present, electronic devices are quite common in use, and with the trend of thinner and smaller electronic devices, the electrical connectors on electronic devices must also reduce the occupied volume, especially the need to install multiple devices that meet different electronic signal transmission specifications. When electrical connectors are used for different plug connectors to be plugged in, since the installation of each electrical connector requires a certain volume and the space between each electrical connector is required, the space between these equal intervals becomes a waste of space .

For example, electronic devices that provide digital audio-visual entertainment need to be equipped with socket electrical connectors that meet the High-Definition Multimedia Interface (HDMI) specification and sockets that meet the Universal Serial Bus (USB) 2.0 specification. Connectors, 3.0 specification socket connectors or multiple socket connectors of other specifications, and when an earphone socket and a microphone socket are also provided, a lot of space will be wasted on the electronic device to install each socket connector.

Therefore, there is still a need to integrate multiple electrical connectors, such as HDMI connectors and USB connectors, to save space. The connector of the interface also has no effective position-limiting structure to avoid the wrong position of the plug and prevent the problem of oblique insertion. In this way, it is the direction that relevant manufacturers engaged in this industry are eager to study and improve.
