An electric wire holding device is composed of an electric wire holding member made of a resin to hold an electric wire, a cylindrical member made of an electrically conductive metal, including an inner surface to be mated around and receive at least a mating portion of the electric wire holding member, and a plurality of protrusions formed around an outer circumference of the at least mating portion of the electric wire holding member for the cylindrical member to be mated therearound. The plurality of protrusions are brought into contact with the inner surface of the cylindrical member.

A junction box is affixed to, and electrically coupled with, a solar panel. The junction box is configured to releaseably engage and disengage accessory modules, thereby allowing accessory modules to be replaced or exchanged easily. Accessory modules are electrically coupled with other accessory modules in the solar panel string. The furthest downstream accessory module is connected to a wire harness, which is connected to a central combiner box.

Electrical enclosures are provided that include arc resistant features designed to add structural strength for arc containment, to inhibit arc propagation, and/or to direct the release of pressure within and/or from the enclosure in order to provide arc resistant electrical enclosures. In general, the arc resistant features may be designed to provide enclosures where in the event of an arc fault, the doors and covers remain closed, parts are not ejected from the enclosure, holes are not produced in the enclosure, indicators located in close proximity to the enclosure do not ignite, and/or grounding connections remain effective. Further, the foregoing features may be designed to provide electrical enclosures that comply with industry guides and standards for arc resistant ratings.

A universal bracket is provided for mounting electrical boxes. The bracket includes a generally rectangular first plate having at least one aperture defined within the first plate. The aperture is shaped to provide access to an electrical box mounted to the first plate, and further includes first and second pairs of diagonally opposite corners. A second plate extends rearward and substantially perpendicular to the first plate and located proximate a first side of the aperture. The first plate further includes one or more fastening portions and a plurality of mounting holes disposed about the fastening portions. One or more of the mounting holes are positioned for mounting the bracket to a vertical structural member adjacent either of two opposite sides of the bracket or a horizontal element adjacent a third side of the bracket, maintaining a particular bracket orientation.

A power terminal feed-through incorporates a metallic body through which extend one or more current conducting pins that are hermetically sealed to the metallic body by a glass-to-metal seal. The metallic body includes an annular lip with a protrusion. During welding installation of the power terminal feed-through, the protrusion serves to assist in the welding process, better controlling the location and definition of the weld between the metallic body and a housing, and to focus the welding heat at the protrusion, thereby protecting the glass-to-metal seal. The glass-to-metal seal can be a single glass insert through which the current conducting pins extend, thereby reducing the pin circle diameter and the overall size of the power terminal feed-through.
摘要:
Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration. When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted.

Various mechanisms are provided relating to plasma-based light source that may be used for lithography as well as other applications. For example, a device is disclosed for producing extreme ultraviolet (EUV) light based on a sheared plasma flow. The device can produce a plasma pinch that can last several orders of magnitude longer than what is typically sustained in a Z-pinch, thus enabling the device to provide more power output than what has been hitherto predicted in theory or attained in practice. Such power output may be used in a lithography system for manufacturing integrated circuits, enabling the use of EUV wavelengths on the order of about 13.5 nm. Lastly, the process of manufacturing such a plasma pinch is discussed, where the process includes providing a sheared flow of plasma in order to stabilize it for long periods of time.
