A connector assembly includes an outer conductive body having a first end configured to mate with a corresponding electrical connector, and a conductive center contact arranged within the outer conductive body. The center contact comprises a first end configured to mate with the corresponding electrical connector and a second end electrically connecting with a first electrical contact of a circuit board. An outer contact is slidably attached to a second end of the outer conductive body and electrically connects with a second electrical contact of the circuit board. An elastic element is provided for biasing the outer contact in a direction away from the outer conductive body and toward the circuit board.

A power adapter for powering portable electronic devices is disclosed. The modifications and enhancements to the power adapter can reduce or eliminate the need for adhesives, flexible circuitry, and/or wiring. The power adapter includes multiple guide rails used to guide a circuit board (carrying components) to electrical springs. The electrical springs provide not only an electrical coupling, but also a mechanical coupling. As a result, wiring and/or adhesives is not required. Additionally, a cap is secured to the enclosure through melting part of the cap by, for example, ultrasonic welding without causing damage to the circuit board, as welding location(s) is/are in locations away from the electrical springs and other sensitive components. The power adapter further includes a connector connected to the circuit board. During assembly, the circuit board can pivot in three dimensions during assembly to align the connector with the cap.

An electrical connector is used to be electrically connected to a mating component. The electrical connector includes one or more shielding members, forming multiple receiving holes; and multiple terminals, including at least one signal terminal and at least one ground terminal correspondingly accommodated in the receiving holes. The ground terminal has a mating portion upward abutting the mating component, an elastic portion pressed vertically to elastically deform, and a positioning portion having a cross-section in a circular shape. The positioning portion and the shielding members are conductively connected to each other by at least three conductive portions, and the three conductive portions are provided to form a triangle. An insulating block is between the signal terminal and a corresponding shielding member to be accommodated in a corresponding receiving hole. The positioning portion with a circular cross-section has a larger area when the volume of the receiving hole remains unchanged.

This contact pin electrically connects a first electrical component and a second electrical component, the contact pin comprising: a pin body having an inside pin element and an outside pin element combined to be extendable; an elastic member that energizes the inside pin element and the outside pin element in the direction in which the pin body expands when the pin body is in a contracted state; and a pressing part that is provided on the outside pin element, and that when the pin body contracts, applies force to the inside pin element that moves in a first direction in the axial direction, the force including a component in a second direction orthogonal to the first direction.

A probe card device and a disposable adjustment film thereof are provided. The disposable adjustment film is integrally formed as a single one-piece structure, and includes a probe hole and a plurality of first slots that are parallel to each other. The disposable adjustment film defines two predetermined lines respectively extending from two opposite lateral edges thereof to the probe hole. The two predetermined lines respectively extend across the first slots. In a plane that the disposable adjustment film is located thereon, when the disposable adjustment film is applied with forces that act in opposite directions and that are parallel to any one of the first slots, the disposable adjustment film is broken into two abandoned films along the two predetermined lines.

A spring-loaded connector (2) includes a waterproof elastic member (50). The waterproof elastic member (50) includes cylindrical parts (51) corresponding to respective contact units (10). When the cylindrical part (51) is sandwiched between a first pin (11) and an intermediate member (13) of the corresponding contact unit (10), the waterproof elastic member (50) seals between the first pin (11) and the intermediate member (13) in a watertight manner while allowing the contact unit (10) to penetrate. The waterproof elastic member (50) includes, between the cylindrical parts (51) that are adjacent to each other, a water-shielding structure (52) for preventing the first pins (11) of the contact units (10) corresponding to the adjacent cylindrical parts from being electrically connected due to presence of water between the first pins (11).

A plug-in connector having terminal provided in terminal receiving cavities. The terminals have memory card engagement sections. A memory card receiving slot is provided in the housing. The memory card receiving slot spans the terminal receiving cavities. A portion of the memory card receiving slot is in alignment with each of the terminal receiving cavities. An elongated opening extends between the memory card receiving slot and the terminal receiving cavities. A memory card is positioned in the memory card receiving slot. The memory card stores data which is identifiable to the specific device and allows the data to be easily conveyed.

An electric connection socket for relaying electric signals between a circuit substrate and an electric component includes: a metal housing which has a through hole enabling communication between the top surface and the bottom surface thereof, and on the top surface of which the electric component is mounted and on the bottom surface of which the circuit substrate is mounted; and a signal pin inserted into the through hole to configure a coaxial line between the inner wall surfaces of the through hole, and which is electrically connected at one end to a signal path first pad electrode of the circuit substrate and is electrically connected at the other end to a signal path terminal of the electric component. On the bottom surface, the metal housing has a ground connection unit which contacts a second pad electrode for grounding formed on the circuit substrate and which grounds the metal housing.

A data communication system can include a low-profile electrical connector that is sized to be mounted onto a PCB in a gap between the PCB and a heat sink that overhangs from an IC that is mounted to the PCB. The data communication system further includes an electrical cable that extends from the electrical connector to an optical transceiver. A cable management laminate can route the electrical cables along a predetermined path. The data communication system can be disposed in a system tray that is configured to force air over the heat sink. The airflow over the heat sink can be adjustable.
