A guide partition wall configured to engage with the slit of the spring member is integrally molded with an inner surface of the case cover.

A connector is disclosed. The connector has a housing and a conductive terminal disposed in the housing. The conductive terminal has a pair of resilient contact arms including a pair of clamping portions clamping a wire therebetween and a pair of releasing portions adapted to move the pair of resilient contact arms away from each other, each of the pair of resilient contact arms includes one clamping portion and one releasing portion disposed at a free end.

The invention provides a modular electrical power transfer device that enables push-in, pull-out connection between electrical power supply wires and interface components. An electrical power transfer device of the invention includes at least two physically isolated electrical buses mounted within a non-conducting housing. Each electrical bus includes a blade connector and one or more wire shark-bite connectors. The wire shark-bite connectors can engage with electrical power supply wires, the resulting mechanical and electrical connections enable the electrical bus to receive power from the connected supply wires and redistribute electrical power to another device connected to the electrical bus. The blade connector can engage with a blade contact from an interface component, the resulting mechanical and electrical connections enable transfer of electrical power from the electrical bus to the interface component. The non-conductive housing includes: (1) blade interface ports through which blade contacts from interface components can access blade connectors on electrical buses mounted within the housing, and (2) wire interface ports through which electrical wires can access the wire shark-bite connectors on electrical buses within the housing. The non-conductive housing optionally includes one or more wire release ports through which a connected wire can be disengaged from a wire shark-bite connector on an electrical bus within the housing.

A connector is disclosed. The connector comprises a housing and at least one conductive terminal received in the housing. The housing has a flange mounted on a first surface of a circuit board and a body extending through the circuit board beyond an opposite second surface of the circuit board. The body has an insertion hole. The at least one conductive terminal has a pair of resilient contact arms contacting a wire inserted through the insertion hole, a pair of solder feet soldered to the circuit board and electrically connected to the pair of resilient contact arms, and a releasing mechanism adapted to move the pair of resilient contact arms away from each other to release the wire.

An arrangement of a circuit board passage terminal on a circuit board includes a housing having a conductor receiving opening for receiving an electrical conductor, and an operating opening for fixing or releasing the electrical conductor upon insertion into the conductor receiving opening; a contact element for soldering and electrically contacting the circuit board passage terminal to a soldering face of the circuit board; and a flange component having an outer face and a mounting face, the mounting face of the flange component resting on the soldering face of the circuit board when the circuit board passage terminal is arranged in a recess in the circuit board.

A power wiring device includes a front housing having a power component at a user interface and a rear housing having a wire interface. The front and rear housings define a cavity. Control electronics are received in the cavity and include a circuit board and a controller coupled to the circuit board. The controller has control circuitry for controlling a power function of the power wiring device. The power component is coupled to the circuit board and affected by the power function. A plurality of power terminals are coupled to the circuit board. The power terminals each have a base, circuit board contacts extending from the base and being terminated to the circuit board, and wire contacts extending from the base. The wire contacts have quick connect interfaces for direct, quick connection to corresponding wires of building wiring.

An electrical distribution box including a bus bar with a quick connect assembly for engaging or disengaging wiring. The bus bar housing defines an interior chamber and includes a wall defining a plurality of holes and release ports therein A space bar within the chamber includes a plurality of spaced-apart fixed contacts and spring contacts. Each spring contact includes an arm that moves towards or away from the fixed contact and is partially aligned with one hole and one release port in the housing. The spring contact moves from an at rest position by inserting a wire through one of the holes. The spring contact locks the wire between itself and the fixed contact. The wire is release by inserting a tool through the release port and applying a linear force to the spring contact, thereby rotating the spring contact away from the fixed contact and releasing the wire.

A lead-through terminal for connecting a conductor so as to conduct electricity includes: a terminal housing having a bearing portion that abuts a wall of an electrical installation when in an installed state, the bearing portion defining on the terminal housing a first housing portion on a first side and a second housing portion on a second side of the bearing portion, a wall feedthrough being provided on the bearing portion; and a pivotable actuation device being provided on the terminal housing to clamp the conductor in a contact position on a current bar and to release the conductor when in an open position. The actuation device is located on the first side to a greater extent when in the contact position than when in the open position, in which the actuation device extends through the wall feedthrough onto the second side at least in part.

A multiple cable disconnect includes a housing having a separable mating end and a wire terminating end configured to receive wires of power cables. The housing has a plurality of terminal chambers with terminals therein. The terminals each have a base, a mating contact extending from the base and a wire contact extending from the base. The mating contact has a mating pad defining a separable mating interface for the terminal for mating with a corresponding mating terminal of the mating connector. The wire contact has plural wire interfaces for mating with plural wires such that plural wires are configured to be terminated to and commoned with each terminal.
