An electronic device testing apparatus with a locking mechanism for locking a press head and a socket plate is provided. When an electronic device is to be tested, a lifting arm is lowered so that a contact portion is in contact with the electronic device, and a locking mechanism is actuated to detain the press head on the socket plate. A pressing force generating device exerts a pressing force onto the electronic device and the socket plate, and at least a portion of a reaction force can be directed back to the locking mechanism. The locking mechanism is adapted to detain the press head on the socket plate. When the pressing force generating device generates a predetermined pressing force to certainly establish electrical connection between the electronic device and the chip socket, the reaction force produced by the chip socket may be distributed over the locking mechanism.

The present disclosure provides a connector assembly. The connector assembly includes a connector housing adapted to engage with a corresponding counter-connector housing. A lever including a first lever arm and a second lever arm is pivotably and sealingly mounted to the connector housing. Each lever arm includes interlocking means for connecting the first lever arm to the second lever arm at a first location. The interlocking means of each of the first lever arm and the second lever arm are configured to define complementary symmetrical surfaces that interlock with one another when the lever arms are pivotably mounted to the connector housing. On mounting the lever arms to the connector housing, the lever is configured to move about the connector housing between an open state and a closed state to secure the counter-connector housing to the connector housing.

A card edge connector includes: an elongated insulative housing comprising two longitudinal walls, a center slot defined between the longitudinal walls, and plural terminal receiving passageways arranged along the longitudinal walls; and plural terminals fixed in the terminal receiving passageways, wherein each of the longitudinal walls defines a first recessed portion extending along a longitudinal direction and plural second recessed portions extending upwardly from the first recessed portion at an outer surface thereof, the second recessed portions are arranged at intervals along the longitudinal direction, the first recessed portion goes through a bottom face of the longitudinal wall, and the second recessed portions does not go through a top of the longitudinal wall.

A connector includes a connector housing having a coupling side for coupling with a complementary connector along a connection direction and a lever assembly including a lever for coupling with the complementary connector. The lever is pivotable around an axis of rotation on the connector housing. The axis of rotation extends essentially perpendicular to the connection direction. The lever extends in at least one position in the connection direction away from the axis of rotation toward the coupling side. The lever assembly has an extension that is movable relative to the lever and that extends the lever assembly in an extended state away from the axis of rotation.

An electrical connector housing is provided with at least one locking clip, which is mounted pivotably via a bearing pin and has a locking region and an actuation region. In order to reversibly lock the electrical connector housing to a mating electrical connector housing, the locking region engages overbearing journals integrally moulded on the mating electrical connector housing. The locking clip has a locking device or means for blocking the pivot movement of the locking clip. In this manner, an accidental release of the plug-in connection can be prevented.

A mechanical fastener for an electrical interface may include a first handle and a second handle The first handle and second handle are located on opposite sides of the mechanical fastener. The mechanical fastener may also include a first housing, a second housing coupled to the first housing, an electrical interface housed in the mechanical fastener between the first and second housings, a first lever intermediary between the first handle and the first housing and mechanically coupled to the second handle, a second lever intermediary between the second handle and the second housing and mechanically coupled to the first handle, a first post coupled to the first handle and the second lever, and a second post coupled to the second handle and the first lever.

A system for managing automated charging, the automated charging management system is provided. The system comprises a charging cord management device, a charging cord connector, a power supply, a device, a first charging cord, and a second charging cord. The charging cord management device is configured to locate the power supply. The charging cord management device is configured to align the second charging cord and the charging cord connector with the power supply. The charging cord connector is configured to be in contact with the power supply without user interaction.

A fluid ejection device, in an example, that includes a housing with the housing including a plurality of lateral hooks to engage with a plurality of posts of a connector, the lateral hooks running, at least partially, parallel to a cable receiving surface wherein a portion of a printed circuit board (PCB) comprising electrical interconnects extends beyond the cable receiving surface to interface with the connector.

A printed circuit board (PCB)-mounted contactor including a PCB with planar surface, source and load terminals fixed to the PCB, and a contact. The contact is supported by the PCB and is movable between open and closed positions. Movement of the contact is parallel to the planar surface. Electrical assemblies having PCB-mounted contactors and methods of controlling current flow in electrical systems with PCB-mounted contactors are also described.

A hardware- and software-supported measuring apparatus for monitoring the operating state of a device has at least one sensor for capturing measurement data of at least one physical parameter that characterizes the operating state of the device, autonomous electronics including a control unit an energy source and a microcontroller, which provides a radio interface for data transmission and/or signal transmission to a control and/or evaluation apparatus, and a housing, which is fastened to the device in a retrofittable manner. The apparatus has at least one sensor and a control and/or evaluation apparatus, which is wirelessly connected to the measuring apparatus for signal transmission and/or data transmission.
