Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector for combined transmission of board-end power and cable signals. Background Technology

[0002] An electrical connector is a common electronic device that enables the transmission of current and / or signals through the contact of its terminals. Electrical connectors typically consist of a male connector and a female connector, each with its own built-in terminals. By inserting or removing the male and female connectors, the terminals between them are connected or disconnected, thus enabling or discontinuing the transmission of current and / or signals.

[0003] Connectors are typically used in conjunction with PCB boards. To meet various requirements, various components are soldered onto the PCB board. Since multiple insertions and removals are required during use, if the connector is damaged, all components, including the PCB board, need to be replaced, resulting in high connector maintenance costs.
