Abstract: An electrical connector includes a rubber core body having a plurality of terminal holes and a plurality of open holes, the terminal holes penetrating front and rear sides of the rubber core body, the open holes being provided on upper and lower sides of the rubber core body and are in communication with the terminal holes respectively; and a plurality of conductive terminals inserted into the terminal holes of the rubber core body. Via this arrangement, the area between the conductive terminals is filled with air instead of solid media, which reduces permittivity. Therefore, the capacitance of conductive terminals is reduced and the impendence is increased.

Abstract: A socket device is installed on a circuit board of an electronic product and includes an insulating housing formed with a contained space for containing an electronic component, a plurality of terminals installed in the contained space, and a holding casing covered around the insulating housing. The insulating housing has at least one horizontal penetrating groove formed at two sides thereof. The terminals are electrically connected with the electronic component. The holding casing forms at least one elastic arm at its two sides, respectively. Each elastic arm forms a pressing portion from a top edge thereof to the contained space for pressing the electrical component, and a guiding portion transversely extended from a free end thereof to the contained space. Each guiding portion is slidably contained in the penetrating groove. Therefore, it can prevent the elastic arm twisted outwardly and the socket device from deforming during the assembly process.
