This invention relates to an electrical connector, a connection device, a method, and an apparatus. The electrical connector includes a housing and a connection structure, wherein the connection structure includes a first valve and a second valve. The first valve is located at the end and isolates the cavity from the external environment. It has a sealed interface for close contact with the connector when it is connected. The second valve is located inside the housing and is spaced apart from the first valve. The first and second valves divide the cavity from the inside to the outside into a first sub-cavity and a second sub-cavity. The first sub-cavity is filled with a liquid conductive medium. The second valve is used to abut against the connector after the connector is connected through the sealed interface, so as to release the liquid conductive medium into the second sub-cavity and make contact with the connector. In this way, due to the flow characteristics of the liquid conductive medium, it can make full contact with the connector without the problem of pressure drop at the contact surface, thereby reducing the contact resistance when connecting to the connector.
