A receptacle connector assembly includes a receptacle cage having first and second side walls extending from a top wall to form a module channel configured to receive a pluggable module. The top wall is non-planar and has a shroud extending therefrom forming a cage polarization feature. The shroud has a first shroud side wall, a second shroud side wall and a shroud top wall forming a polarization feature channel configured to receive a polarization feature of the pluggable module.

A fastening device for fastening an electrical terminal to an electrically conducting post includes a spring and a locking device retaining the electrical terminal on the electrically conducting post in a locked position of the fastening device. The spring is at least partially loaded in the locked position.

A connector includes: an outer housing that includes an inserting part having a tubular shape, and is fixed to a first surface of a wall part in a state in which the inserting part is inserted into a hole part of the wall part; and an inner housing including a main body that is inserted into the hole part from a second surface side to be engaged with the outer housing, and a projecting part projecting from the main body. The projecting part projects from the main body toward a rear side in an insertion direction with respect to the hole part, and is configured such that a rear end surface of the projecting part is located to be flush with the second surface when the main body is completely engaged with the outer housing.

A plug connector part for connecting to a mating plug connector part includes: a housing part; an inlet part that is connectable to the housing part, the inlet part having a plug section on which at least one contact element is arrangeable for a plug-in connection to the mating plug connector part; and a locking frame having at least one first latching element, the locking frame being latched in a first mounting position to the inlet part via the at least one first latching element in order to attach the inlet part together with the locking frame to the housing part. The inlet part in a position attached to the housing part is connected in a positive-locking manner to the housing part via at least one second latching element. The locking frame is movable from the first mounting position relative to the inlet part to a second mounting position.

A mounting system and method secure a power distribution unit within a substrate at sites where access behind the substrate is unavailable to a worker effecting the installation. The power distribution unit is coupled to a trim plate for displacement relative to the trim plate when the trim plate is engaged with an obverse surface of the substrate. Displacement of the power distribution unit relative to the trim plate from a first position into a second position beyond the obverse surface, and then release of the power distribution unit for return toward the first position, in response to a biasing force, enables a retention member to lock the power distribution unit in place within the substrate. Selective removal of the power distribution unit from the substrate is accomplished by lifting the trim plate from the obverse surface of the substrate to effect release of the retention member from the power distribution unit, thereby releasing the power distribution unit from the substrate.

A power supply device includes a power supply housing having an accommodating space and an accommodating opening, a hybrid wire-to-wire connector structure and a circuit board disposed in the accommodating space. The hybrid wire-to-wire connector structure includes a connecting seat and an adapter seat. The connecting seat has a signal line terminal and a power line terminal. The connecting seat is disposed in the accommodating opening through an annular rib. The adapter seat has a signal conduction end and a power conduction end. The adapter seat has formed a hook corresponding to the annular rib. The connecting seat and the adapter seat are combined through the signal conduction end inserted in the signal line terminal, the power conduction end inserted in the power line terminal and the hook clamped with the annular rib. Therefore, the power and signal connectors are integrated so as to simplify the assembly.

Receptacles are provided for mating with plugs to establish electrical connections. The receptacles include a shell having a body, and a flange attached to the body. The flange has a projection extending therefrom. The receptacle also has an electrically-insulating insert positioned at least in part within the body; and one or more electrical contacts positioned at least in part within the insert. The receptacle is configured for mounting on a panel. The projection contacts a mounting surface of the panel, to establish a localized contact area that provides bonding between the receptacle and panel.

A shelf system having electrical supply includes at least one backboard and at least one power adjustment mechanism. Each power adjustment mechanism has a socket and a plug. The backboard has a through hole. The socket has an inserting cylinder inserted in the through hole and a clamping portion. The clamping portion has a connecting cylinder, a flange disposed on the connecting cylinder, and a wedge buckle disposed on the connecting cylinder and spaced from the flange. The backboard is sandwiched between the wedge buckle and the flange. The plug is a cylindrical portion inserted in the connecting cylinder. The plug can be arranged on the backboard and the socket can be inserted on the plug. Even if the shelf has been assembled, a user may quickly install the power adjustment mechanism into the shelf.

A plug connector part for connecting to a mating plug connector part includes: a housing part; an inlet part that is connectable to the housing part, the inlet part having a plug section on which at least one contact element is arrangeable for a plug-in connection to the mating plug connector part; and a locking frame having at least one first latching element, the locking frame being latched in a first mounting position to the inlet part via the at least one first latching element in order to attach the inlet part together with the locking frame to the housing part. The inlet part in a position attached to the housing part is connected in a positive-locking manner to the housing part via at least one second latching element. The locking frame is movable from the first mounting position relative to the inlet part to a second mounting position.

Structures, methods, and apparatus that provide connector receptacles that have a reduced tendency to scratch and otherwise mar connector inserts, have an aesthetically-pleasing appearance, and have an improved tactile response when inserts are inserted. Various examples reduce scratches and wear by utilizing domes, cylinders, balls, or other structures as finger contacts in a connector receptacle. Another example provides aesthetically-pleasing connector receptacle enclosures by forming receptacle enclosures using the same type of material, or material having the same or similar color or texture, as is used for enclosing the electronic device that includes the receptacle. Another example provides an aesthetically-pleasing receptacle enclosure by forming receptacle enclosures that are, in part or in whole, contiguous or formed with the housing. Another embodiment provides a connector receptacle having a housing where a portion of the housing has been removed to save space.
