Abstract: A linear radio frequency identification antenna is provided and includes an insulating material, a shielding material, and a conductive wire. The shielding material connects with the insulating material to form a closed body. The conductive wire is covered by the closed body such that the conductive wire, the insulating material, and the shielding material together form a linear-shaped body.

Abstract: A receptacle connector is provided and includes an insulating case, a securing device and a cover. The insulating casing includes a plurality of terminal receiving passageways, a plug receiving space, a pair of protrusions on two sides of the plug receiving space. A securing device receiving space is disposed on one of the two sides. The securing device includes a horizontal portion, a first vertical portion and a second vertical portion extending downward from the horizontal portion, a first soldering portion extending horizontally from the first vertical portion, a second soldering portion extending horizontally from the second vertical portion. An engagement portion is positioned between the first vertical portion and the second vertical portion. The cover is pivotally connected to the insulating casing and includes a first protrusion receiving passageway and a second protrusion receiving passageway which communicate with each other and correspond in position with the pair of protrusions.
