Improved PV assemblies for converting solar radiation to electrical energy and methods of installation thereof are disclosed herein. PV arrays comprising a plurality PV modules are also described herein. A PV assembly can comprise a plurality of PV modules arranged into rows and/or columns of a PV array. A PV module can comprise a plurality of solar cells encapsulated within a PV laminate. In some embodiments, a PV module includes a frame at least partially surrounding the PV laminate. A PV assembly can further comprise at least one flexible grounding connector positioned between a plurality of PV modules, adjacent rows of PV modules in an array and/or a column of PV modules in an array. A flexible grounding connector can comprise a first and a second engagement head for engaging a first and a second PV module. A flexible grounding connector can further comprise a flexible body portion coupling first and second engagement heads. The flexible body portion of the flexible grounding connector can be electrically conductive so as to provide an electrical grounding path between first and second PV modules and accommodate any misalignment or offset between first and second PV modules.

A screw insert includes a body configured to engage a threaded fastener and transmit a torque to the threaded fastener, a first head connected to the body, a second head connected to the first head, and a neck extending between the first head and the second head. The neck is configured to break causing the second head to separate from the first head in response to a torque applied to the second head exceeding a predetermined value. A collar may be fitted over the neck. The threaded fastener includes an internal bore into which the body of the screw insert may be fit. The threaded fastener and screw insert may be used in an electrical connector having a lug including an axial bore configured to receive a wire and one or more threaded bores extending through the lug between the axial bore and an exterior of the lug. A tool for use with the fastener is also disclosed.

A module-terminal block connection structure includes: a printed wiring board; a terminal block which is disposed on one surface of the printed wiring board and is formed into a three-dimensional shape by a conductive material, the terminal block being fixed to the printed wiring board; a power module which is disposed on the other surface (rear surface) of the printed wiring board and includes an electric circuit and a press-fit type lead pin used as a circuit terminal; and a conductive portion which is electrically connected to the terminal block, includes a hole (through-hole) for press-inserting the lead pin thereinto, and is electrically connected to the power module while the lead pin is press-inserted into the hole.

The invention relates to a clamp (10), more particularly PEN clamp, for connection of electrical conductors, and is characterized by the use of pilot screws (28) as the clamping screws and/or in the way the pilot screws (28) are axially and/or radially secured.

An electrical connection module system includes a first connection plate with a first connection end and at least one first foot section, a first screw nut, and a dielectric holder. The dielectric holder has a first reception region for receiving the first screw nut. The first connection plate can, when the first screw nut is placed in the first reception region, be pushed onto the dielectric holder and be brought into a first target position such that the first screw nut is arranged between the dielectric holder and the first connection end and is held by the first connection end in the first reception region in such a way that the first screw nut cannot fall out.

A bus bar that includes a main body having a plate shape for arranging a terminal to be electrically connected to the bus bar; and an upright provided at a side in a widthwise direction of the main body, wherein: the main body has an open hole into which a shaft of a bolt is to be inserted, and the upright has an inner surface with which a head of the bolt can come into contact in a rotational direction.

A terminal attaching/detaching device includes a housing, an engaging member, and a movable member. The engaging member is configured to move in a first direction toward a terminal inserted in the housing to engage with the terminal, and is configured to move from the terminal inserted in the housing in a second direction to disengage from the terminal. The movable member is configured to move in concert with the engaging member in the moving process thereof in the first direction, and is configured to move the engaging member from the terminal inserted in the housing in the second direction, so that the engaging member is disengaged from the terminal.

The invention relates to a housing assembly protected against contact for a module connector, with a housing which comprises a passage opening extending through the housing in a direction of connection, and with a screw with a screw head arranged in the passage opening, where the screw is locked in the passage opening in a pre-assembly position. Such a housing assembly can be assembled quickly and in a simple manner and at the same time is completely protected against contact.

A device for connecting a conductor to a terminal, including a screw slidable inside the terminal of an apparatus, the screw having a first head portion to be actuated and screwed into a head nut and a second body portion to be screwed into a body nut mounted in a casing of the apparatus, the screw being mobile between an open position in which the screw is screwed only into the head nut so as to allow the introduction of a tag into the terminal between the screw body and a pad and a closed position in which the screw is screwed into both the body nut and the head nut so as to clamp the tag between this screw body and the pad. This device includes a device for synchronizing the threads respectively associated with the screw body and the screw head, this device ensuring automatic returning of the screw body towards the screw head when the screw body is brought into contact with the body nut during screwing until synchronization of the two threads.
