The electrical wiring junction box comprises an insulated base, a plurality of wiring apertures, a plurality of bar apertures, a plurality of conductive bars, and a plurality of clamp screws. The insulated base may comprise a plurality of tiers at different vertical heights. Each of the plurality of tiers may be associated with an electrical attribute. A first conductor of a first circuit may be electrically coupled to a second conductor of a second circuit by connecting the conductors to the same bar at one tier. An individual conductor may be connected to the individual bar by placing the stripped end of the individual conductor into an individual wiring aperture selected from the plurality of wiring apertures and then tightening an individual clamp screw at the individual wiring aperture where the individual conductor is inserted.

A connector comprises a pressing assembly and a contact prevention member. The pressing assembly has a first receptacle receiving a first conductor, a pressing member which can be activated from an exterior of the pressing assembly, and a chamber. The contact prevention member has a contacting slot open to an interior of the contact prevention member and a second receptacle receiving a second conductor. The contact prevention member is insertable into the chamber of the pressing assembly in an insertion direction.

A connection structure for connecting a power cable and a conductor lead-out rod to minimize electrical resistance of a contact surface, and conductor connection device of a power cable may be provided with at least one conducting bolt configured to be fastened into a fastening hole to apply pressure to conductive particles injected into an accommodation space so as to electrically connect a conductor part and a conductor lead-out rod; and a fixing bolt configured to be fastened into the fastening hole to fix the conductor part inserted into an accommodation groove of the conductor lead-out rod.

An electrical connector carries large amounts of electrical current between two circuit boards with low resistance and low self-inductance by means of an interdigitated anode and cathode, thereby providing low dynamic voltage loss. The connector also may include, near where power will be consumed, an interposer board with on-board capacitance to provide even lower dynamic voltage loss. The connector has application to delivering low-voltage, high-current power from a power supply on a first board to electronics on a second board: the low resistance provides low voltage drop for a load current that is constant, while the low inductance and the capacitors provide low voltage fluctuation for a load current that changes. These issues are of great importance, for example, in designing high-performance computers.
