A power distribution unit (PDU) having a connector to connect to an input power supply and a plurality of power outlet sockets for receiving plugs having a number of pins. Each power outlet socket has a mechanical locking mechanism movable between a locked position and an unlocked position when a plug is inserted into the power outlet socket to lock and unlock a plug pin in the power outlet socket. Absent actuation the locked position is adopted. Each power outlet socket includes an externally, manually actuatable, first release element, and an internally, electrically actuatable, second release element. A power sensor detects whether or not power is being drawn and, for power outlet sockets which currently host a plug and are not drawing power, the second release element is actuated by the PDU so as to unlock the mechanical locking mechanism, thereby freeing up the associated plugs for removal.

Disclosed herein is a use-limiting connector for limiting use of an electrical tool. The use-limiting connector includes an electrical circuit, a plunger, movable between a first position and a second position, and a biasing member, configured to urge the plunger into the first position and configured to incrementally uncoil into respective torsional states as the plunger moves between the first position and the second position. With the plunger in the first position and the biasing member in a first one of the torsional states, the biasing member closes the electrical circuit. As the plunger moves from the first position to the second position, the plunger moves the biasing member to open the electrical circuit.

The invention relates to an assembly for marking at least one connection of a computer system. The assembly comprises a housing with an outer wall, in which a recess is formed. Furthermore, at least one connection is provided, which is accessible from outside the housing via the recess of the housing. The assembly is characterized in that a labelling element can be secured within the housing such that at least one section of the labelling element which can be provided with a marking and which is assigned to the at least one connection projects outwards from the housing through the recess. Furthermore, the invention relates to a connection module and to a labelling element.

A method for electrically insulating a connector module mounted on a printed circuit board assembly, the method including coating a first portion of a piece of sheet metal with an insulation material, forming the piece of sheet metal into a metal frame, wherein a second portion of the piece of sheet metal not coated with the insulation material is formed into a grounding pin, assembling the connector module, wherein components of the connector module include the metal frame, a housing, and a set of external pins, and mounting the connector module on a printed circuit board to form a printed circuit board assembly, wherein the set of external pins are electrically connected to a corresponding set of vias on the printed circuit board, and the grounding pin is electrically connected to a ground on the printed circuit board.

A HVAC unit manufacturing method and a HVAC system are disclosed herein. In one embodiment, the HVAC system includes: a controller having control board terminals, a parallel wiring harness having a first and a second connection header, the first connection header coupled to the control board terminals, and a switch having terminals. The terminals of the switch including: a pair of functional terminals configured to indicate a status of the switch and a pair of jumpered terminals independent of the pair of functional terminals and internally connected together within the switch, wherein designated combinations of the terminals indicate a circuit configuration for employing the switch in the HVAC system with each of the terminals having a particular design that dictates a specific corresponding connection header be used for each of the designated combinations, wherein a single one of the designated combinations of the terminals corresponds to the second connection header.

A power outlet device including a outer element, a light indicating element and a outlet module is provided. The outer element has a first portion and at least one second portion. The first portion is configured out of the second portion. At least one first through hole is configured in the second portion. The first portion and the second portion are opaque portions. The light indicating element has at least one lighting set corresponding to one second portion. Each lighting set has at least one lighting unit. Each lighting unit is configured in the inner periphery of each first through hole of the second portion. The light indicating element is configured in the outlet module, and the outer element is configured on the light indicating element. Wherein, each lighting unit is exposed from the corresponding first through hole.

A connector includes an outer housing, an inner housing provided with an engagement latch, a slide channel, and rails each being a groove, and a sliding member provided with support arms engaged with the respective rails, and a protrusion to latch the engagement latch. The slide channel is formed with a slide surface extending along the rail. The support arms each include a lower surface facing the slide surface, and an upper surface inclined relative to the slide surface. The groove forming the rail is formed as a recess including a bottom surface, a first side surface, and a second side surface. The second side surface faces the upper surface of the support arm, and is formed at an inclination angle corresponding to that of the upper surface.

Disclosed is a system for operating a network incorporating high-density connections for increased efficiency, network operation and management. The high-density connections are incorporated into the patch panel, network switch, and cables that connects them, as well as into cable analyzers and printed circuit boards (PCBs) which allow for a complete network within a single computer running virtualization software.

A connector body configured to interconnect with a corresponding mating connector body includes a pair of longitudinal struts that extend from the connector body and are oriented substantially parallel to a mating axis of the connector body. The longitudinal struts each define an enclosed lateral slot having a closed end and a connector position assurance (CPA) device that is interlocked within the lateral slots and moveable from an initial position to a final position along the mating axis after the connector body is coupled to the corresponding mating connector body. The CPA device has a lateral cross bar extending into each of the lateral slots thereby retaining the cross bar in the lateral slots. The CPA device and the connector body are integrally formed by an additive manufacturing process.
