Disclosed are a flat cable and a WIFI connection line, where the flat cable includes flat wires and an insulation layer wrapped around the flat wires. The flat wires include one power line, four signal lines and two ground lines arranged at intervals, and a width of the power line and a width of each ground line are both greater than a width of each signal line.

An integrated circuit (IC) socket comprising a housing with a land side, an opposing die side, and sidewalls around a perimeter of the housing. The housing comprises a first dielectric. A plurality of socket pins extends from the land side of the housing through socket pin holes in the housing over the die side of the housing. A second dielectric is within the interstitial regions between the socket pins and sidewalls of the socket pin holes. A frame structure extends around at least a portion of the perimeter of the housing, and a mesh structure is embedded within the first dielectric. The mesh structure has plurality of mesh filaments extending between the plurality of socket pin holes and coupled to the frame structure.

A shunt device is used to be mated with an adapter socket of a connector configured on a circuit board to shunt electric current of the connector. The shunt device includes an insulating housing and a first electric terminal. The insulating housing has a bottom surface. The first electric terminal is fixed on the insulating housing. The first electric terminal has a first contact portion and a first leg that extends out of the insulating housing from the first contact portion, so as to provide a first cable connection surface for being connected to at least one wire cable. The first contact portion is exposed from the bottom surface and has a contact surface that is parallel to the bottom surface, so as to abut against a shunt contact surface of the adapter socket.
