A terminal fitting is provided with a tubular connecting portion and a deflectable and deformable resilient contact portion arranged in the connecting portion. The connecting portion includes a bead extending in a front-rear direction and projecting inward toward a contact point of the resilient contact portion on a base wall portion facing the contact point. An outer surface of the base wall portion includes recesses recessed inwardly in both front and rear end parts of the bead, and a shorting terminal facing portion located outwardly of bottoms of the recesses between the both front and rear end parts of the bead.

Provided is a board-to-board socket, including a socket body, socket terminal, and socket strengthener. The socket body includes a bottom wall, socket side walls, socket guide parts formed at lateral ends of the socket body, and an island part protruding upwards from the bottom wall. Socket guide parts each include a plug guide part receiving cavity, longitudinal outer peripheral wall, and lateral outer peripheral walls. The socket strengthener includes a main body part, lateral outer peripheral wall, and elastic arm parts. Tops of the elastic arm parts bend and extend towards longitudinal outer sides to form hitching part cavities hitched on top faces of the lateral outer peripheral walls.

A connection terminal and a connector are disclosed. The connection terminal has a terminal body, at least part of which is installed in a housing of a connector; and a first connection part arranged at one end of the terminal body and extending outside the housing to electrically connect with a bus bar. The first connection part has a plurality of side surfaces, and any one of the adjacent two side surfaces is selectively formed to match and connect with a surface of a connection end of the bus bar. In the present invention, the installation orientation of the connector can be any one of four or more different directions, which expands the application range of the connector.

A connector cable includes a plurality of contacts placed in a row and a plurality of cables connected to the plurality of contacts. The plurality of cables includes at least three pairs of high-speed differential signal lines for transmitting high-speed differential signals, at least one non-high-speed differential signal line for transmitting a non-high-speed differential signal, and a plurality of ground terminals. The plurality of ground terminals is allocated to contacts on both ends among the plurality of contacts and a contact between two pairs of high-speed differential signal lines or between one pair of high-speed differential signal lines and one non-high-speed differential signal line to limit the number of consecutive pairs of high-speed differential signal lines to two.
