High frequency electrical connector

A method of assembly electrical connector components, comprising the steps of:

• inserting a pin of a plug component into a socket of a receptacle component, thereby electrical connecting the plug component and the receptacle component;
• axially move a coupling member, that is rotatably coupled to the plug component, from a disengagement position to an engaged position;
• engaging the coupling member with a support panel, in which the receptacle component is mounted, to form a mechanical connection between the plug and receptacle components;
• and
• sealing the engagement between the coupling member and the support panel,
• wherein the coupling member is moved axially with respect to the plug component after the pin is inserted into the socket.

An assembly, comprising:

• a receptacle including a conductive shell supporting at least one socket contact therein, the conductive shell having a front end and a back end configured to electrically connect to a printed circuit board;
• a support panel associated with the receptacle;
• a plug including a conductive shell supporting at least one pin contact configured to mate with the at least one socket contact of the receptacle, the conductive shell of the plug having a front end configured to mate with the front end of the receptacle, and a back end configured to electrically connect to a coaxial cable, and a sealing member disposed on the conductive shell, the sealing member being configured to provide an environmental seal at or near a mating interface of the receptacle and plug;
• and
• a coupling member coupled to the conductive shell of the plug, the coupling member being configured to engage the support panel,
• wherein the receptacle has a receptacle ground connection located inside or on the conductive shell and the plug has a plug ground connection located on the conductive shell of the plug, and the receptacle and plug ground connections form a primary grounding path through the assembly and wherein the receptacle and plug have secondary ground connections, respectively, that form a secondary grounding path through the assembly separate from the primary grounding path, and
• wherein the receptacle primary ground connection is one or more inner contact points inside of the conductive shell of the receptacle;
• and the plug primary ground connection is one or more inner contact points on an inner surface of the conductive shell of the plug configured to connect with the one or more inner contact points of the receptacle primary ground connection to form the primary grounding path.
