A socket connector assembly includes a socket connector and a cable assembly coupled to the socket connector. The socket connector includes a socket frame having a socket opening and a socket substrate received in the socket opening. The socket substrate includes lower socket conductors electrically connected to a host circuit board and upper socket contacts having deflectable spring beams. The cable assembly includes an outer housing and a paddle card received in a pocket having paddle card contacts at a mating end on a lower surface interfacing with the upper socket contacts. The cable assembly includes cables terminated to the paddle card communicatively coupled to corresponding paddle card contacts. The side walls of the outer housing engage an outer surface of the socket frame to locate the paddle card relative to the socket substrate.

Examples described herein include a backplane keying mechanism. The backplane keying mechanism may include a backplane, a first connector, a second connector, a first block for the first connector, and a second block for the second connector. The first block and the second block may be moveable as one unit on the backplane from a first state to a second state. In the first state, the first block allows the first connect to connect to a first type of device and the second block allows the second connector to connect to the first type of device. In the second state, the first block prohibits the first connector from connecting to the first type of device and the second block prohibits the second connector from connecting to the first type of device.

The disclosed apparatus may include (1) a power distribution module that (A) distributes power to a network device that forwards traffic within a network and (B) includes a series of interlock blocks keyed to (I) enable power supply modules whose electrical ratings satisfy a certain threshold to be installed to the network device and (II) prevent other power supply modules whose electrical ratings do not satisfy the certain threshold from being installed to the network device and (2) at least one power supply module that (A) has an electrical rating that satisfies the certain threshold, (B) includes a flange that is keyed to fit between the interlock blocks of the power distribution module, and when installed to the network device by way of the power distribution module, (C) provides power to the network device that forwards traffic within the network. Various other apparatuses, systems, and methods are also disclosed.

An electronic device includes a first main body, a first electrical connector, and an insert member. The first main body has an insertion end and one or more holes located at the insertion end. The first electrical connector is disposed at the insertion end. The insert member is coupled to the first main body through the one or more holes and includes a plurality of ribs and a plurality of removed portions. Each of the ribs extends away from the insertion end. The ribs and the removed portions are sequentially and linearly arranged according to a coding pattern.

An electrical device includes a connection part and a cover part connected to the connection part. A mounting part is accommodated and situated in the connection part, and a first circuit board is connected to the mounting part in a coded manner. A second circuit board is situated in the cover part, which is connected to a frame part in a coded manner. The first circuit board is connected to a plug connector part, and the second circuit board is connected to a mating plug connector part. A leading guide for a plug connection is provided on the mounting part, which becomes active when the cover part is connected to the connection part. The frame part being able to be connected to the mounting part in a coded manner.

An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.

A module arrangement for a modular field device connection unit comprises a frame module having an interface receptacle, an interface module adapted to be inserted into the interface receptacle along a module insertion path, and a resetting mechanism adapted to reset the movable coding element into the neutral position by insertion of the interface module into the interface receptacle and/or removal of the interface module from the interface receptacle. The interface module has a cartridge receptacle and a movable coding element. The movable coding element is movable from a neutral position into a coding position by insertion of a cartridge member into the cartridge receptacle. The resetting mechanism has a trigger element at least partially protruding into the module insertion path.

An automation module includes a housing that has a front and rear sides, top and lower sides and a left and right sides, wherein a printed circuit board is arranged within the housing parallel between the left and right sides of the housing, the lower and top sides are formed at least as a ventilation grid to enable cooling inside the housing, where a first plug connector is arranged on the printed circuit board proximate to the top side, an adapter is detachably arranged on the top side, where the adapter has a second plug connector and forms an encoding element such that the adapter includes pins arranged such that, during an insertion-withdrawal operation of the second plug connector into the first plug connector, the pins pass through openings in the ventilation grid and an insertion-withdrawal operation of the second plug connector into the first plug connector is therefore possible.

The disclosed apparatus may include (1) a power distribution module that (A) distributes power to a network device that forwards traffic within a network and (B) includes a series of interlock blocks keyed to (I) enable power supply modules whose electrical ratings satisfy a certain threshold to be installed to the network device and (II) prevent other power supply modules whose electrical ratings do not satisfy the certain threshold from being installed to the network device and (2) at least one power supply module that (A) has an electrical rating that satisfies the certain threshold, (B) includes a flange that is keyed to fit between the interlock blocks of the power distribution module, and when installed to the network device by way of the power distribution module, (C) provides power to the network device that forwards traffic within the network. Various other apparatuses, systems, and methods are also disclosed.

A modularized server comprises a rack, a switching mechanism, and a removable electronic device. The rack comprises a first slot and a second slot. The switching mechanism is disposed on the rack. When the removable electronic device is inserted into the first slot, the removable electronic device is operable to drive the switching mechanism to a switching position. The switching mechanism at the switching position can stop another removable electronic device different from a specific design of the removable electronic device from being inserted into the second slot.
