Abstract: A board-to-board plug, comprising an insulating seat (20) integral to a metal insert (30), several signal terminals (40) arranged inside the insulating seat (20), and a shielding housing (10) coated outside the insulating seat (20). The insulating seat (20) comprises an engagement end (21) provided with terminal slots (214), terminal blocks (24) formed by extending from the engagement end (21) to the rear direction, and a pair of extension arms (22) formed by extending from both transverse sides of the terminal block (24) to the rear direction. The metal insert (30) comprises a board body portion (31) formed between a pair of extension arms (22), and several grounding terminals (37) bent from the front end of the board body portion (31) and extending into the terminal slots (214). The grounding terminals (37) and the signal terminals (40) are arranged at intervals.

Abstract: Provided is a board-to-board radio frequency plug, including a plug body; a plurality of plug terminals and a plurality of metal spacers integrally formed in the plug body; and a shielding shell wrapping the plug body and the plurality of plug terminals. The plug body comprises: a body base; a body outer-wall formed by integrally extending upward from a periphery of the body base; an island portion formed by integrally extending upward from middle of the body base; and an insertion space formed between the body outer-wall and the island portion. The plug terminals extend on an outer periphery of the island portion, each metal spacer is provided between two adjacent ones of the plurality of plug terminals, and each metal spacers penetrates through the island portion and the insertion space in a perpendicular direction. The present disclosure further provides a board-to-board radio frequency receptacle.
