A cable enclosure includes a housing defining an opening through which an interior of the housing is accessible. An end plate is releasably secured to the housing to cover the opening such that the interior of the housing is not accessible. The end plate includes a first conductive leg in electrical communication with a first cable within the housing. The end plate also includes a second conductive leg in electrical communication with a second cable within the housing. The end plate further includes a conductive member movable between a first position and a second position. When in the first position, the conductive member is in contact with the first conductive leg and the second conductive leg. When in the second position, the conductive member is not in contact with at least one of the first conductive leg or the second conductive leg.

A conductor connection terminal with an insulating material housing, wherein the insulating material housing has a mounting opening and a conductor insertion opening, with a closure part, wherein the closure part can be inserted into the mounting opening, with a contact insert, wherein the contact insert has a busbar and a clamping spring, the clamping spring with a clamping leg extending toward the busbar with a spring clamping edge for clamping an electrical conductor, and with a first latching connection arranged between the closure part and the insulating material housing, wherein the closure part and the insulating material housing can be fixed to one another by means of the first latching connection, wherein a second latching connection is arranged between the closure part and the contact insert, wherein the closure part and the contact insert can be latched together by the second latching connection.

The invention relates to a terminal block structure includes an insulative base, a conductive terminal, a pressing element, and a clamping elastic piece. The insulative base has a chamber, a wire insertion hole and an open trough disposed on the same side of the insulative base as the wire insertion hole. The conductive terminal is fixed in the chamber and arranged correspondingly to the wire insertion hole. The pressing element includes a pivoting portion, an arm, a handle, and a pressing portion. The pivoting portion is pivotally connected to the insulative base. The arm protrudes from the insulative base through the open trough. The handle is movable beside the wire insertion hole. The clamping elastic piece is disposed in the chamber. An end of the clamping elastic piece is operatively moved to inside or outside of the wire insertion hole through the pressing portion.

Embodiments of the invention provide an electrically-powered submersible pump. The pump has a pump housing, a ring-style terminal block including an annular component having a plurality of terminals, a motor contained within the pump housing, and a power source in communication with at least one of the plurality of terminals. Each of the plurality of terminals is spaced apart about the annular component and at least one terminal of the plurality of terminals extends outwardly from the annular component. The motor in communication with at least one of the plurality of terminals.

An electrical connection box is provided with a conductive bus bar, an insulating housing body, a cover, and a power supply line. The cover opens or closes with respect to the housing body at a fully open position and a fully closed position. The housing body has a connector at a position exposed to the outside, with the connector configured so that a terminal provided at a tip of the power supply line is attachable or detachable to or from the connector. A restriction portion, which restricts the power supply line from moving in the longitudinal direction is provided in the cover. In the state where the terminal is connected to the connector, the tension is created on the power supply line in the longitudinal direction by the restriction portion during moving the cover from the fully closed position to the fully open position side.

A connector comprises a locator configured to position a cable. The locator has a front-end surface, a first surface and a second surface and is formed with a positioning groove. The first surface and the second surface are located at opposite sides of the locator, respectively, in the upper-lower direction (Z-direction). The positioning groove has a front groove, a rear groove and a coupling groove. The front groove is recessed rearward from the front-end surface and extends from the first surface to the coupling groove along the upper-lower direction. The rear groove is recessed from the second surface along the upper-lower direction and extends rearward from the coupling groove. When the locator positions the cable, the front groove receives a front regulated portion of the cable, and the rear groove receives a rear regulated portion of the cable.

A conductor connecting structure includes: first and second conductors having terminal portions; a support having recessed portions; first screw members accommodated in the recessed portions; and second screw members that co-fasten the terminal portions of the first and the second conductors by screwing to the first screw members. The recessed portions have first and second wall surfaces that face each other in an opposing direction, and restricting surfaces along the opposing direction to restrict the rotation of the first screw members. The first and second wall surfaces configure a retaining portion to retain the first screw member before being screwed, and an allowable portion located closer to the inlet of the recessed portion. The distance between the first and the second wall surfaces in the allowable portion is greater than the distance in the retaining portion.

A conductor connection terminal with an insulating material housing, a busbar component, a first clamping leg and a second clamping leg, wherein the first clamping leg and the second clamping leg are arranged on a clamping spring or on different clamping springs, respectively, wherein the first clamping leg and the busbar component form a first clamping point for a first electrical conductor to be clamped, and the second clamping leg and the busbar component form a second clamping point for a second electrical conductor to be clamped, wherein the busbar component comprises a first conductor receiving section and a second conductor receiving section at diametrically opposite areas of one another, wherein the first conductor receiving section and the second conductor receiving section are connected to one another via a connecting section.

A modular plug-in bus wiring system for electrical connections. The system includes an adapter module, the adapter module including at least a housing wherein the housing includes a front side containing at least an electrical connector, a back side, an upper end, a lower end, and at least a receptacle. The system includes at least a plug configured to insert in the at least a receptacle wherein the at least a plug is connected to at least a cable that includes at least an electrically conductive wire. The at least a plug includes a ventral surface, a dorsal surface, a first side and a second side.

A terminal block assembly for wire connection of a motor, which includes: a terminal block body; one or more bus bar supports which are formed on the terminal block body; one or more bus bar bodies which have bent shapes corresponding to outer surfaces of the bus bar supports and are rested on the terminal block body or the bus bar supports; one or more terminal connectors which are formed at one ends of the bus bar bodies and are held in contact with one or more connector terminals; and one or more coil connectors which are formed at the other ends of the bus bar bodies and are connected to one or more coils of a motor.
