A power adapter assembly structure is disclosed and includes a housing, a circuit board, a socket and an elastic element. The circuit board including a first abutting surface and the socket including a second abutting surface are fastened in the housing. The elastic element connected between the circuit board and the socket includes a main body, a first hanging arm and a second hanging arm. The first hanging arm and the second hanging arm are disposed at two opposite ends of the main body, and constantly abuts the first abutting surface and the second abutting surface, respectively. A first gap is formed between the main body and the first abutting surface, and less than a first length of the first hanging arm. A second gap is formed between the main body and the second abutting surface, and less than a second length of the second hanging arm.

An interposer includes a planar substrate and a pad array formed on a bottom side of the planar substrate to connect with a pin array within a CPU socket. A serial computer expansion bus connector is formed on the top side of the planar substrate and is electronically coupled to a portion of the pad array. The interposer further includes a perimeter structure adapted for securing to a CPU carrier. The interposer may be included in a kit with a heatsink securable to the CPU socket, wherein the heatsink includes a contact area for contacting the interposer and applying a load to the interposer. A printed circuit board assembly may include first and second CPU sockets that are connected by a CPU interconnect, where the interposer may be installed in the first CPU socket and a CPU may be installed in the second CPU socket.

A connector includes a substrate, a plurality of cables connected to a side of the substrate, and a plurality of terminals disposed on a surface of the substrate and electrically connected to the cables. Each of the terminals includes a connecting portion, a bending portion and an extending portion. The connecting portions are electrically connected to the corresponding cables. Each of the bending portions extends from the corresponding connecting portion and includes a turning segment. The extending portion is formed by extending from the corresponding bending portion toward a direction away from the surface of the substrate.

An electrical connector includes a mating section for receiving the mating tab therein. The mating section has a first contact arm and a second contact arm. The first contact arm is spaced from the second contact arm by a first slot. The first contact arm has a first length which is different than a second length of the second contact arm. A first normal force exerted by the first contact arm on the mating tab is equal to a second normal force exerted by the second contact arm.

A piston assembly for a spring-loaded contact, comprising a piston body, arranged to be received into a guiding cylinder of the spring loaded contact, a piston head, with a contacting surface arranged for contacting an external part, a clip arranged to mate with a conductive portion of the spring loaded contact, wherein the piston body comprises a through hole, the clip being arranged into the through hole, and wherein the piston head is attached to the piston body by an ultrasonic welded portion.

Devices and methods for a sealed electrical connector are described herein. Some embodiments include a spring connecting a first PCB to a second PCB, wherein the spring includes a first end portion in contact with the first PCB, a second end portion in contact with the second PCB, and a middle portion extending between the first end portion and the second end portion, a spacer surrounding the middle portion of the spring, a first seal seated in a first groove of the spacer and in contact with the first PCB, and a second seal seated in a second groove of the spacer and in contact with the second PCB.

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.

Systems for interfacing a printed circuit board assembly (PCBA) adapter module to a receiver housing are provided. The receiver housing may have a first interface mounted on the receiver housing via a first mount and the PCBA adapter module may have a second interface mounted on the adapter module via a second mount. One of the interfaces has a protruding feature that aligns the interfaces when matingly engaged, while the other interface has a centering hole opposite the protruding feature. The first centering hole is enlarged with respect to an axis of an insertion-angle plane such that the protruding feature substantially clears the centering hole without causing either interface to exceed a limit of free-play between that interface and its respective mount.

Connector receptacles that can provide audible feedback to inform a user that a card has been properly inserted, and can include structures to protect contacts in a connector receptacle from damage due to an improper card insertion. An example can provide a connector receptacle having a click module to provide audible feedback indicating that a card has been fully inserted. Another example can provide a connector receptacle having movable contacts that can remain out of an insertion path until the card is at least partially inserted.

An electrical ground connector for use as part of a test connector in an integrated circuit (IC) device testing apparatus having a resilient connector for electrical grounding and comprising a dual elastomer contact stacked vertically above a rigid ground block. The height of the ground block can be adjusted to compensate for the lack of height of the dual elastomer contacts, so that the entire connector has enough height to maintain electrical connection between a load board of the testing apparatus and the IC device.
