A connector includes an insulator, a plurality of pairs of terminals provided on the insulator, and a resistance element. The plurality of pairs of terminals include at least one pair of cable terminals electrically connected with a cable and at least one pair of vacant terminals that are unused. The resistance element is electrically connected between each pair of vacant terminals.

A Peripheral Component Interconnect Express/Serial Attached SCSI (PSAS) female connector includes a frame member, a terminal member, and a cover member; the frame member including a terminal groove disposed in the frame member and a tilt portion disposed in the terminal groove adjacent to a plug end; the terminal member inserted in the frame member and including a Serial Advanced Technology Attachment (SATA) 7 pin terminal, a Serial Attached SCSI (SAS) 40 pin terminal, a 15 Pin signal terminal, a 6 Pin terminal, and a 4 Pin terminal. When the PSAS female connector is engaged with the male connector, the SATA 7 Pin terminal and the SAS 40 Pin terminal are pressed by a terminal of the male connector to be bent toward an outer lateral side of the terminal groove to contact the elastic plate of the cover member. The present invention effectively improves the cross interference during high speed transmission, thereby achieving the Generation 5 performance requirement.

In a connector assembly in which a first connector that includes a first insulator, first terminals, and a first shell and is mounted on a first board and a second connector that includes a second insulator, second terminals, and a second shell and is mounted on a second board are connected with each other, a first ground pattern that has a frame-like shape and is formed on the first board is soldered to the first shell with first solder, and a second ground pattern that has a frame-like shape and is formed on the second board is soldered to the second shell with second solder. An inner space in which the first terminals and the second terminals are positioned is completely shielded from the outside without any gap.

A battery connection device for connecting to a vehicle battery includes a top member, a bottom member having a side wall and a bottom wall. The side wall, top member, and bottom member form a box-like enclosure. The bottom wall includes a through-hole with a circumferential face, an adapter member arranged inside the box-like enclosure extends at least partially through the through-hole for connection with the battery. A dimension of the adapter member is smaller than a dimension of the through-hole to form a gap between an outer face of the adapter member facing the circumferential face and the circumferential face, and flexible connection member connected to the adapter member and to the bottom member and closing the gap between the outer face and the circumferential face. The flexible connection member includes an electromagnetic shield for shielding electromagnetic radiation and a seal for sealing the gap against dust and/or moisture.
