Board-to-board plug

A board-to-board plug, comprising an insulating seat, a metal insert, conductive terminals provided in the insulating seat, and a shielding housing enclosing an outer side of the insulating seat,

• wherein the insulating seat and the metal insert are formed into one piece,
• wherein the insulating seat comprises an engagement end provided with terminal slots, terminal blocks formed by extending from the engagement end to a rear direction, and a pair of extension arms formed by extending from both transverse sides of the terminal blocks to the rear direction,
• wherein the conductive terminals comprise signal terminals and grounding terminals arranged at intervals,
• wherein the metal insert comprises a board body portion formed between the pair of extension arms,
• wherein one of the grounding terminals comprises a retaining portion retained in one of the terminal blocks, a solder pin formed by extending backward from the retaining portion, and an elastic contact arm extending forward from the retaining portion into one of the terminal slot, and
• wherein solder pins of the signal terminals are exposed at the terminal blocks, and
• wherein the solder pins of the grounding terminals pass through the terminal blocks to extend to the board body portion and is electrically connected to the board body portion.

A board-to-board plug, comprising an insulating seat, conductive terminals provided in the insulating seat, a cable assembly provided at a rear end of the insulating seat and electrically connected to the conductive terminals, and a shielding housing coated outside the insulating seat,

• wherein the insulating seat comprises an engagement end provided with terminal slots formed by passing therethrough in a vertical direction, an internal insertion space extending transversely and communicated with the terminal slots is formed at the engagement end, and the conductive terminals are arranged respectively corresponding to the terminal slots and exposed to the internal insertion space,
• wherein the cable assembly comprises cables, one of which comprises at least a central conductor and a braided layer at a periphery of the central conductor,
• wherein the board-to-board plug further comprises an isolation assembly, and the isolation assembly comprises:
• a connecting portion formed transversely in the engagement end, and spacers formed by extending longitudinally downward from an end of the connecting portion;
• and each of the conductive terminals is arranged at an interval between two adjacent ones of the spacers, respectively, and the isolation assembly is electrically connected to the braided layer.
