A contact in one aspect of the present disclosure comprises a fixing portion, an elastic contact piece, and a pair of projecting tabs, which are formed as an integrated entity from a metal thin plate. The projecting tabs project from the fixing portion at positions on both sides of the elastic contact piece. A dimension of the elastic contact piece in a width direction, which matches the direction of an interval between the projecting tabs, is a first dimension. The projecting tabs are formed such that each projecting tab is a flat plate having the same thickness as the thin plate. The projecting tabs are arranged such that the thickness directions thereof are the same direction, in locations that have inner surfaces of the projecting tabs facing each other, and an interval between the inner surfaces is a second dimension greater than the first dimension.

A contact for an electrical plug connector comprises a plug portion and a contact spring. The plug portion has an opening receiving a pin contact in an insertion direction. The contact spring is connected by at least one spring arm base to the plug portion and extends from the at least one spring arm base toward the opening in a direction opposite the insertion direction. The contact spring exerts a contact force on the pin contact perpendicular to the insertion direction.

An electrical contact includes a contact body and a contact spring. The contact spring is disposed in the contact body and has a locking arm locking the contact spring in a housing. The locking arm moves in a vertical direction away from the contact body when a withdrawal force acting on the contact spring exceeds a retaining force of the contact spring.

An electronic card connector, defining an insertion direction, an ejection direction, and a transverse direction perpendicular to the insertion direction, includes an insulative housing and a number of terminals retained in the insulative housing. The terminals include a row of first contacts disposed along the insertion direction. Each first contact has a first affixed portion and a first contacting portion located at a peak therein. Each of the first contacts extends along the transverse direction. The first contacting portions of the neighboring first contacts are located offset along the insertion direction. The first contacting portions and associated first affixed portions of the first contacts are distanced differently in the transverse direction.

An electrical connecting device having a main body and a displacement body mounted in a linearly movable manner relative to one another in a longitudinal direction. The main body has a cavity that accommodates a longitudinal section of the displacement body or vice versa. The length of the longitudinal section accommodated in the cavity is variable by a relative longitudinal movement of the main body and the displacement body. The main body has conductor tracks extending in the longitudinal direction and insulated from one another. The displacement body has sliding elements insulated from one another and resting on and electrically contacting a contact surface of a respective one of the conductor tracks. The conductor tracks are arranged on a main body surface of the main body. The main body surface is round in a cross-sectional plane perpendicular to the longitudinal direction or is formed by a plurality of surface sections angled in relation to one another. The sliding elements project from a displacement body surface of the displacement body. The displacement body surface is round in the cross-sectional plane or is formed by a plurality of surface sections angled in relation to one another. The contact surfaces of at least two of the conductor tracks are angled in relation to one another.

An electrical connector includes multiple terminals formed by cutting from a metal plate and bending. The portion of the metal plate with the terminals being removed is defined as a base plate. Each terminal has a base portion and an elastic arm connected thereto. The base portion is at least partially horizontally provided to be coplanar to the base plate. A cutting slot is formed between the base plate and the base portion. A through slot is formed between the base plate and the elastic arm. An insulating body is provided with through holes running vertically therethrough. A portion of the cutting slot and the through slot are exposed in a corresponding through hole. The terminals include signal terminals and ground terminals. The base plate forms a connecting portion between the through slot and the cutting slot of each ground terminal to be connected to the ground terminal.

A back-to-back ultra-slim module (USM) includes an inline USM (USMi) connector and a top mount USM (USMt) connector. The back-to-back USM assembly can be made as a double-sided module to allow a stacked module configuration to save system area. The stacked module has a USMi module inline with the system board on one side of the system board, and a USMt module vertically offset from the other side of the system board. The stacked module can have a thermal layer between the USMi module and the USMt module.

A card connector, a card holder, and a terminal device, where the card connector includes a plurality of first terminals and one or more second terminals. The first terminals are arranged to form a first card access area that installs a first card, and the first terminals are configured to be electrically coupled to the first card. The one or more second terminals are distributed on a periphery of the first card access area, the first terminals and the one or more second terminals form a second card access area that installs a second card, and the first terminals and the one or more second terminals are configured to be electrically coupled to the second card.

An interposer assembly including a plate and a plurality of conductive contacts extending through plate passages for forming electrical connections with pads on overlying and underlying substrates.
