An electrical connector with a flexible printed circuit (FPC) received may carry electrical signals between the FPC and a substrate. Latching mechanisms may serve to position the cap on the body such that the positions facilitate the insertion and retention of the FPC in the cap for a good electrical connection. The FPC may be received loosely in the cap when the cap is in a first position on the body. When the cap is depressed into a second position, the FPC may be compressed between the cap and the body. Mating ends of the contacts may electrically connect to exposed conductive elements of the FPC. Mounting ends of the contacts in the contact housing may electrically connect to the conductive elements on a substrate. If the contacts are compression contacts, the terminals of the contacts may deflect or compress when a force is exerted upon them. The electrical connector may have a sealing surface that is adapted to provide suitable compression against an FPC received by the electrical connector so as to keep out gases or fluids.
