One end of the first choke inductor is coupled to a transceiver end of a RF transceiver and the other end is coupled to a first control end of a RF antenna controller. The transceiver end is coupled to a first conductor. The first bypass capacitor is coupled between the other end and a digital ground terminal. The first coupling capacitor is coupled between the digital ground terminal and a RF ground terminal. The second conductor is coupled to the RF ground terminal and a second control terminal of the RF antenna controller at a second connecting end of a RF cable. The second bypass capacitor is coupled between the second control terminal and the digital ground terminal.

A radio-frequency connector assembly includes a radio-frequency line, connector male terminals, connector female terminals, and a circuit board, wherein each connector male terminal includes a male terminal substrate; each connector female terminal includes a female terminal substrate; the connector male terminal further includes a shielding case which shields the male terminal substrate and is conductive with the radio-frequency line in a grounding manner; and the connector female terminal further includes a shielding frame which is internally provided with the female terminal substrate and is circumferentially seamless entirely, and the bottom end of the shielding frame makes contact with the circuit board to form an annular contact region, so that signals of the connector female terminals will not leak sideways; and the shielding cases can prevent signal leakage and signal interference from the top of the shielding frame, so that matched signal terminals are kept in a fully-shielded operating environment.

A contact device includes a first contact element extending along a straight line and a second contact element inclined with respect to the first contact element. The first contact element has a connecting body extending along the straight line, a first contact portion, and a flap. The first contact portion has a first contact socket. The flap is connected to a first fixed end at a first side of the connecting body. The first contact portion is connected to the connecting body. The flap extends along the first straight line to the first contact portion and a free end of the flap is arranged at a distance from the first contact portion. The second contact element has a second contact portion engaging the first contact socket and electrically contacting the first contact portion.

An electrical connector includes first and second adjacent electrical contacts that each define respective first and second mating ends, the first mating end of a first one of the first and second adjacent electrical contacts defines a first contact surface, the second mating end of a second one of the first and second adjacent electrical contacts defines a second contact surface electrically isolated from the first contact surface; and a dielectric material positioned between the first and second adjacent electrical contacts. When a mating connector applies a force to the first contact surface and the second contact surface, the first and second mating ends and the dielectric material all move in a first direction.

A connector includes a cable including at least one core wire and a shielding wire arranged around the core wire with an insulating member interposed therebetween, a plug part connected to the cable and capable of fitting with a receptacle, a primary molded part including a connection portion between the core wire and a conductive member of the plug part, and a secondary molded part arranged at a lead-out portion of the cable. The dimension of the primary molded part is an outer diameter or a thickness of the plug part.

A backplane connector includes a housing, a number of terminal modules assembled to the housing, and a mounting block. The housing includes a base, a first side wall and a second side wall. Each terminal module includes a first signal terminal and a second signal terminal. The first signal terminal has a first mounting foot, and the second signal terminal has a second mounting foot. The housing includes a receiving groove at a bottom end of the base. The mounting block is received in the receiving groove. The mounting block is made of electroplated plastic. The mounting block has an opening for the first mounting foot and the second mounting foot to extend through. As a result, the backplane connector has a better shielding effect.
