A method and apparatus for board-to-board circuit connection. In one example, a connector system includes a printed circuit board having a first set of electrical pads and at least one electrical component positioned between the first set of electrical pads and an adapter frame. The adapter frame includes a second set of electrical pads on a bottom surface and connected to the first set of electrical pads of the printed circuit board and a third set of electrical pads on a top surface and electrically connected to the second set of electrical pads. The adapter frame further includes a chamber configured to house the at least one electrical component and having electrical shielding that forms at least a partial Faraday cage around the at least one electrical component. A connector receptacle having a set of pins is connected to the third set of electrical pads.

A pin includes a head, a base connected to the head, a tail connected to the base, and clasps extending from the tail. The head includes two or more of the following: a hook, a first side notch, a second side notch, and an end notch. A module includes a substrate, a first pin mounted to the substrate at a first location, and a second pin mounted to the substrate at a second location. A distance between a tip of the first pin and a tip of the second pin is greater than a distance between the first location and the second location.

A connector for interfacing with a circuit board includes a body having opposing first and second face surfaces and defining a plurality of ports extending between the face surfaces. A plurality of center conductors extend in respective ports between the face surfaces. Support elements engage the center conductors to secure the center conductors generally centered in the respective ports. Each center conductor includes a pin portion positioned proximate to the first face surface and a plunger portion positioned to extend beyond the second face surface. The plunger portion moves longitudinally with respect to the connector second face surface for varying the distance of an end of the center conductor from the second face surface to allow adjustability in the interfacing of the connector with a circuit board or other signal handling component.

A socket connector includes a base formed of a conductive upper base part and a conductive lower base part which are affixed together, a conductive barrel seated within a passageway and a pocket formed by the base, at least one conductive biasing member engaging the base and the barrel, a conductive contact seated within the barrel, and an insulative housing in which the base is positioned. The housing is coupled to the base. At least one of the upper and lower base parts has a plurality of pins depending from the respective wall which seat within plated through holes of a printed circuit board. A coupling pin is mounted in the socket connector and is further coupled to an electrical component.

An electrical connector includes two adjacent terminal groups in a front-rear direction, including a front terminal group and a rear terminal group. Each terminal group includes a ground terminal and a signal terminal. The ground terminal has a first base portion and a first elastic arm. The first elastic arm includes two extending arms and a through slot formed therebetween. The signal terminal has a second base portion and a second elastic arm. The first elastic arm and the second elastic arm are used to be electrically connected to a mating member. In a same terminal group, the signal terminal is located in front of the first base portion, and the second elastic arm runs through the through slot. The mating member presses on the first elastic arm. The first elastic arm of the ground terminal of the rear terminal group abuts the ground terminal of the front terminal group.

An electrical connector includes an insulative housing with a plurality of passageways extending through opposite upper and lower surfaces thereof, and a plurality of contacts retained in the corresponding passageways, respectively. The contact includes a main body, a spring arm extending from an upper end of the main body with a contacting section at a free end region thereof, and a tab extending upwardly from the main body for assembling the contact into the corresponding passageway. An auxiliary part extends from a side edge of the main body at an angle with a solder pad at the bottom end for securing a solder ball thereto. The tab is dimensioned to allow a fixture to grasp thereon for applying a downward force thereto during downwardly inserting the contact into the passageway, and is optionally adapted to be removed when the contact is moved to almost the final position.
