ADVANCED-CONNECTEK INC.

An electrical connector, including an insulating body, multiple terminals, a metal shell, a collar, and a water-proof glue, is provided. The terminals are disposed in the insulating body. The metal shell is disposed outside the insulating body and surrounds the insulating body and the terminals. The collar is sleeved onto an outer wall of the metal shell. The collar has a first plate portion, a second plate portion, and a bending portion. The bending portion is connected between the first plate portion and the second plate portion. The first plate portion is connected to the outer wall of the metal shell, and the second plate portion is away from the outer wall of the metal shell. The water-proof glue is disposed between the second plate portion of the collar and the bending portion and the outer wall of the metal shell.

An electrical connector including a plurality of terminals, a first insulating body, a second insulating body, a shell, and a waterproof member is provided. The terminals are respectively retained in the first insulating body and the second insulating body. The shell is sheathed to the first insulating body and the second insulating body. The shell has a front edge and a rear edge opposite to each other along an insertion direction. The front edge is used for mating another electrical connector. At least one opening is formed by the rear edge and the second insulating body. The first insulating body and the second insulating body are separated from each other. A space is formed by the first insulating body, the second insulating body, and the shell. The space is communicated with an external environment via the at least one opening. The waterproof member is filled into the space.

An electrical receptacle connector includes an insulated housing, a plurality of receptacle terminals, and a metallic shell. A hollow portion is between a base portion and a tongue portion of the insulated housing, and body portions of the receptacle terminals penetrate through the base portion and the tongue portion and are partially exposed from the hollow portion. The metallic shell covers the insulated housing and covers the hollow portion to form a potting space at the hollow portion. The metallic shell has a potting opening corresponding to the potting space. When a sealing body is poured into the potting opening, the sealing body is provided between the insulated housing and the receptacle terminals. Hence, the waterproof function of the electrical receptacle connector can be achieved.

An electrical receptacle connector includes a metallic shell, an outer shell, an insulated housing, and receptacle terminals. The receptacle terminals are held at the insulated housing. The metallic shell covers the insulated housing. The outer shell covers the metallic shell. The metallic shell has a reduced length to allow the exposure of the tongue portion. Elastic pieces of the outer shell extend toward the recessed holes of the metallic shell. When an electrical plug connector is mated with the electrical receptacle connector, the housing of the electrical plug connector contacts the elastic pieces of the electrical receptacle connector, so that the holding force between the electrical plug connector and the electrical receptacle connector can be increased. Hence, when the electrical plug connector is mated with the electrical receptacle connector, the high-frequency interference issue during signal transmission can be reduced.

An electrical connector assembly includes an electrical plug connector and an electrical receptacle connector corresponding to the electrical plug connector. The electrical plug connector includes a plug fixation housing, a plug movable housing, and plug terminals. The plug terminals are on the plug fixation housing, and the plug movable housing is floatingly arranged on the plug fixation housing. The electrical receptacle connector includes a receptacle fixation housing, a receptacle movable housing, and receptacle terminals. The receptacle terminals are on the receptacle fixation housing, and the receptacle movable housing is floatingly arranged on the receptacle fixation housing. An electrical plug connector and an electrical receptacle connector are also provided.

A board-to-board connector assembly includes a receptacle connector and a plug connector mated with each other. The receptacle connector includes a first body, first terminals and a pair of first metal members. The first body includes an island structure and a first receiving slot surrounding the island structure. The first terminals are respectively disposed on a first side and a second side of the first receiving slot, the first and second sides being opposite to each other. The first metal members are respectively disposed on a third side and a fourth side of the first receiving slot, the third and fourth sides being opposite to each other. The first metal member includes a base extending to a bottom on the third side or a bottom on the fourth side, and a pair of first elastic arms extending from the base and facing away from each other.

A board-to-board receptacle connector includes a receptacle connector and a plug connector adapted to be mated with the receptacle connector. The receptacle connector includes a mating base and receptacle terminals held in the mating base. Each receptacle terminal has a mating portion and two clamping arms. The mating portion of each receptacle terminal corresponds to a corresponding terminal groove of the mating base, and the two clamping arms of each receptacle terminal oppositely extend from two sides of the mating portion. The plug connector includes a fixed base and plug terminals respectively arranged the fixed base, each plug terminal includes a connection portion protruding from one of two surfaces of the fixed base, and the connection portion of each plug terminal is adapted to contact an inner side of the clamping arm of the corresponding receptacle terminal.

A floating-type board-to-board connector assembly includes a plug connector and a receptacle connector. The plug connector includes a fixed base, a floating base, and plug terminals. Each plug terminal includes a flat contact portion, a flexible contact portion, and a soldering portion. For each plug terminal, the flexible connection portion is in an operation space of the fixed base, and two ends of the flexible connection portion respectively extend toward the flat contact portion and the soldering portion. The receptacle connector includes a base portion and receptacle terminals held in the base portion. For each receptacle terminal, a flexible contact portion is in an insertion portion of the base portion and adapted to contact the flat contact portion. The floating base is connected to the fixed base through the flexible connection portions of the plug terminals.

A floating-type board-to-board connector assembly includes a plug connector and a receptacle connector. The plug connector includes a fixed base, a floating base, and a plurality of plug terminals. The floating base is in an operation space of the fixed base, the floating base includes a plurality of guiding posts, and two ends of each of the plug terminals are respectively connected to the fixed base and the floating base. The receptacle connector includes a base portion and a plurality of receptacle terminals. The base portion has a plurality of guiding post holes, and each of the guiding post holes corresponds to a corresponding one of the guiding posts, each of the receptacle terminals is held in the base portion, and each of the receptacle terminals is adapted to contact a corresponding one of the plug terminals.
