Abstract: A slot connector for receiving a circuit substrate has a long insulating housing with a central slot. Banks of terminal receiving grooves are arranged at sides of the insulating housing. Each bank has terminal receiving grooves having alternatively arranged signal terminal receiving grooves and grounding terminal receiving grooves. A signal terminal is received within each respective signal terminal receiving groove. Each signal terminal includes a contact portion, a flexible arm, a fixing portion and a pin portion. A grounding terminal is received with each grounding terminal. Each grounding terminal includes a circuit substrate, a flexible arm, a fixing portion, and a pin portion. At least one of the contact portion, elastic arm, and fixing portion of each grounding terminal is larger than that of the respective portion of the signal terminal.

Abstract: A cable assembly has a flat cable, and a plurality of connectors connected to the flat cable. Each connector includes a plurality of signal terminals, at least one grounding piece and an insulating body. A specific grounding device is formed on a specific position of the grounding piece. The spacing wall of the grounding piece slot and the signal terminal slot of the insulating body with respect to the base of the grounding piece is hollowed so that when the grounding piece is inserted into the grounding piece slot, the specific grounding device passes through the hollow portion to directly contact at least one specific signal terminal in the adjacent signal terminal slot. The signal transferred by the at least one specific signal terminal will ground without passing through the specific conductive wire of the bank wire.

Abstract: An improvement of the holder of an electric connector comprises a terminal seat, a plurality of terminals, embedding seats and embedding pieces. The terminal seat is made by insulating materials. A pair of symmetric embedding seats having a U shape are installed on the two ends of the terminal seat for receiving respective embedding pieces. A guide groove, a pivotal hole, fixing inclined surfaces is formed on the inner wall surface of the embedding seat, so that the embedding pieces is inserted into the embedding seat with a fixing angle, and the rotary angle of the embedding piece is confined. The lateral wall surface of the terminal seat is flat. Holding holes with a size thinner than that of the terminal hole are extended from the two sides of the terminal hole for firmly securing the terminal within the terminal seat.
