The invention relates to a direct plug-in connector (1) for establishing an electric connection between a conductor (30) and a metallized through opening (40) of a printed circuit board (50). The direct plug-in connector (1) has a fastening element (4) and a contact (2) with at least one first contact arm (3a). The first contact arm (3a) is configured for the electric connection of the conductor (30) to the metallized through opening (40). The fastening element (4) can assume a fastening position and a release position, the fastening element (4) being configured to fasten the direct plug-in connector (1) to the metallized through opening (40) in the fastening position.

A socket structure is provided and includes a circuit board, an insulating base, a pin and a conductive component. The insulating base is disposed on the circuit board and includes a first side and a second side opposite to each other. The pin is disposed between the first side and the second side. The conductive component is connected between the circuit board and the insulating base and includes a first arm, a second arm and a connecting part. The first arm and the second arm are connected to each other through the connecting part. The first arm is fixed on the second side of the insulating base and connected to the pin and includes a first fixing end connected to the circuit board. The second arm includes a second fixing end connected to the circuit board.

An assembly includes at least three layers of sheet metal lying directly on top of one another and joined in a stack of sheet metal. The layers of sheet metal are each joined in pairs by a clinching joint. At least one layer of sheet metal arranged between one of the pairs of layers of sheet metal joined by the clinching joint and an outer side of the stack each have an access opening aligned with the clinching joint.

A board mounting type connector includes a housing, a plurality of contact portions to be extending from the housing toward a circuit board, and a plurality of protrusions to be protruding from the housing toward the circuit board. The plurality of contact portions are aligned along a width direction at a first position in a fitting direction. The connector and a mating connector are to be fit each other in the fitting direction. The width direction intersects the fitting direction. The plurality of protrusions are aligned along the width direction at a second position in the fitting direction. A distance between the first position and a position of a center of gravity of the connector in the fitting direction is longer than a distance between the second position and the position of the center of gravity in the fitting direction.

A plug-in power distribution unit is readily installable, removable, and replaceable by skilled or non-skilled persons. The units include one or more conventional electrical power plugs for engaging a conventional wall outlet or the like, and one or more proprietary electrical power connectors for engaging with a compatible connector of a modular electrical power system. Optionally, multiple circuits may be accommodated by the plug-in power distribution unit.

A receptacle connector having a plurality of airflow holes positioned to avoid heat buildup inside a receptacle shell, preventing deformation to the housing of a short, high density connector during solder reflow. The airflow holes may be in a bent portion joining a top face and rear face of the shell. The receptacle connector may be mounted to a substrate, such as a printed circuit board, leaving a gap between the connector and the substrate, forming an airflow passage between the substrate and the receptacle connector, enabling heated air to reach mounting portions of terminals of the connector during soldering, but reducing heat buildup within the shell. The passage, alone or in combination with a cutout in a face of the shell, may expose terminal contacts of the receptacle connector to provide for easy inspection and rework of the solder joints between the terminal contacts and the substrate.

A connector including a housing mounted on a printed circuit board (PCB) and including a sidewall having an empty space that is open to one side and a fixing portion extending from an outer surface of the sidewall, the fixing portion passing through the PCB, a connection terminal having a part passing through the sidewall of the housing and the other part passing through the PCB and configured to be electrically connected to the PCB, and a connection unit including a terminal receiving portion and a coupling portion extending from an outer surface of the terminal receiving portion toward a position of the fixing portion to be mechanically coupled with a part of the fixing portion extending out of the PCB.

A cable assembly includes a first cable and a second cable that is arranged co-axial to the first cable. Proximal ends of the first and second cables are provided with a connector assembly. The connector assembly from each proximal end is adapted to connect with one another, or a pair of receptacle ports located within a PCB, the PCB being disposed alongside the co-axially arranged first and second cables.

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.

An electrical connector includes an insulative housing and conductive power and signal terminals. The housing has a mating interface that engages with a mating connector. The power terminals and signal terminals are attached to the housing and exposed at the mating interface. The housing is configured to be mounted on a circuit board such that a side housing surface is aligned with an edge of the circuit board. The connector may have a right-angle configuration and may mate with a right-angle mating connector such that an edge of the circuit board of the connector and an edge of a circuit board of the mating connector are aligned edge to edge and directly face each other to form a flat pair, or may mate with a vertical mating connector to form a corner pair. The power terminals and the signals terminals may be arranged in arrays of columns and rows.
