An electrical connector electrically connects a first electrical module and a second electrical module, for insertion by the first electrical module along a first direction. The electrical connector includes a first group of terminals arranged in a row along a second direction, having multiple signal terminals and multiple ground terminals and forming at least one first terminal unit and at least one second terminal unit. Each of the terminals has a contact portion, a tail portion, and a middle portion located between the contact portion and the tail portion. In the second direction, the middle portions of the first terminal unit form a first row of the middle portions, and the middle portions of the second terminal unit form a second row of the middle portions. Viewing from the second direction, the first and second rows of the middle portions are staggered, thus improving the crosstalk.

Various embodiments of a wireless connector system are described. The system has a transmitter module and a receiver module that are configured to wirelessly transmit electrical energy and/or data via near field magnetic coupling. The wireless connector system is designed to increase the amount of wirelessly transmitted electrical power over a greater separation distance. The system is configured with various sensing circuits that alert the system to the presence of the receiver module to begin transfer of electrical power as well as undesirable objects and increased temperature that could interfere with the operation of the system. The wireless connector system is a relatively small foot print that is designed to be surface mounted.

An electrical connector (100) includes an insulative housing (1), a plurality of contacts received in the insulative housing, and a first conductive member (24). The contacts include a pair of first grounding contacts (212) for transmitting grounding signal, and a pair of first signal contacts (211) for transmitting a differential signal. The pair of first grounding contacts and the pair of first signal contacts are arranged in a first row. The pair of first signal contacts is disposed between the pair of first grounding contacts. The first conductive member is electrically connected with both of the first grounding contacts in at least two different locations.

An electrical connector assembly includes a plug connector and a receptacle connector each equipped with a grounding bar. The plug connector includes an insulative plug housing with a mating tongue, and a plurality of stationary plug contacts retained in the plug housing. The plug contacts include a plurality of signal contacts and a plurality of grounding contacts. The grounding bar forms a set of first fingers, a set of second fingers and a set pf third fingers respectively located at different positions, to respectively contact the different three positions of the respective grounding contacts.

A dual-row cable structure is applied to a first circuit board and a second circuit board. A board-to-board connector is on the first circuit board, and the first circuit board includes a first group of contacts and a second group of contacts. An electrical connector is on the second circuit board. The second circuit board includes a third group of contacts and a fourth group of contacts. The dual-row cable structure includes a wire assembly including high-speed signal wires, low-speed signal wires, one or more power wires, and one or more ground wires. The high-speed signal wires are connected to the first group of contacts. The low-speed signal wires, the power wire, and the ground wire are respectively connected to the second group of contacts. The third group of contacts and the fourth group of contacts are respectively connected to the other end of the wire assembly.

An electrical terminal includes a base, a first elastic arm and a second elastic arm formed side by side by extending upwardly from an upper end of the base, and a protruding portion. The first elastic arm has a mating portion, and the second elastic arm has a contact portion. The protruding portion protrudes and extends from a first side of the first elastic arm, and the first side of the first elastic arm is adjacent to the second elastic arm. A lower surface of the protruding portion has a contact surface overlapping with the contact portion in a vertical direction, such that the contact portion upwardly abuts the contact surface. When the chip module presses downwardly on the electrical terminal, the contact portion can move on the contact surface, such that the chip module does not need to press downwardly on the contact portion with a relatively large pressure.

A socket for a card-edge connector comprises a bottom frame end, a top frame end, a first frame portion, a second frame portion, and a slot. A card-edge connector inserted into the slot may proceed from the from the top frame end towards the bottom frame end between the first frame portion and second frame portion. The socket may comprise a pin contact in the first frame portion. The pin contact may comprise a bottom pin that protrudes out of the first frame portion into the slot near the bottom frame end, a pin shaft located within the first frame portion and connected to the bottom pin section, and a top pin section connected to the pin shaft and located within the first frame portion. The socket may comprise a pin fulcrum located within the first frame portion. The pin fulcrum may contact the pin shaft at a fulcrum point.

A power interface may include a housing, a connection body, and a partition piece. The connection body may be arranged in the housing, configured to be connected to a circuit board, and include at least one power pin assembly. Each power-pin assembly may include a pair of power pins spaced apart from each other. The partition piece may be sandwiched between the pair of power pins, extend along a second direction perpendicular to the first direction, and include a tail end connected to the circuit board and a head end away from the circuit board and opposite to the tail end in the second direction. At least one of the head end and the rail end may define a through hole, and a reinforcing rib may be arranged in the through hole. A mobile terminal and a power adapter are also provided.
