摘要:
A conductive fastener assembly, system, and method, wherein the fastener assembly includes a fastener, a fastener sleeve, a nut, and a lubricant coating. The lubricant coating is deposited on a distal portion of a fastener shank and is omitted from the rest of the fastener. To overcome the stresses placed on the fastener sleeve by the insertion of the fastener shank largely devoid of a lubricant coating, the fastener sleeve is reinforced by one or more of an increased thickness, a high-strength alloy, and a soft metal coating.

A solar panel rack may comprise one or more sheet metal brackets configured to attach solar panels to the solar panel rack. The sheet metal brackets may include clinching tabs configured to be clinched to features on the solar panels to attach the solar panels to the solar panel rack. The sheet metal brackets may further include protrusions configured to facilitate electrical contact between the brackets and the solar panels when the clinching tabs are clinched to features on the solar panels. The sheet metal brackets may additionally or alternatively include positioning tabs configured to contact features on the solar panels to position the solar panels in desired locations on the solar panel rack.

The invention relates to a system (5) for attaching electrical equipment (1) to a metallic support (20) and comprising: a pin (3) designed to be inserted through a through-housing (21) of the metallic support (20) and a metallic insert (10) of the electrical equipment (1), and means (30, 32, 34) of insulating the metallic support (20), extending between the metallic support (20) and the metallic insert (10), and characterized in that it further comprises mechanical retention means (40, 42) designed to apply load to the insulating means (30, 32) so as to keep them in contact with the metallic support (20) and with the metallic insert (10).
摘要:
A method for directing electrical current to prevent sparking from the interaction between a composite structure and lightning or static electrical charge, the method including the steps of forming a hole in a composite structure; and positioning a bushing into the hole to create an interference fit between the bushing and the composite structure, wherein the bushing is formed of a material that has a coefficient of thermal expansion close to the coefficient of thermal expansion of the composite structure and the bushing provides an electrical path between a fastener disposed in the bushing and the composite structure.
摘要:
An earth bolt with a surface treatment layer are a method of surface treatment of the earth bolt rae provided. The surface treatment includes a tin-zinc plated layer, a colored chromate film layer and a silicate coating layer. Since the earth bolt with the surface treatment layer has improved electro-conductivity and anti-rusting property, it may protect electrical/electronic components fitted to a vehicle from electromagnetic shock and remove noise therefrom, thereby improving reliability of a vehicle body.

A conductive sleeved fastener assembly includes an electrically-conductive fastener having a fastener head and a fastener shank extending from the fastener head and an electrically-conductive fastener sleeve receiving the fastener shank of the fastener and a fastener sleeve flange provided on the fastener sleeve and disposed in direct contact with the fastener head of the fastener. A method of preparing a conductive sleeved fastener for use is also disclosed.
摘要:
The systems, apparatus, and methods disclosed herein provide access to systems located within a closed structure, such that the systems are traditionally difficult for humans to access. Exemplary structures include an engine compartment, airplane wing, or fuselage. This access allows a system located within the structure to be electrically coupled with an electrical I/O device located outside the structure. Access to a system located within the closed structure is provided by way of a hole.
摘要:
A pipe mounting unit with grounding function, which includes a pipe holding section and a body fixing section, is formed by superposing a lid to a conductive plastic housing, between which there is disposed a conductive rubber clamp that holds a pipe in contact. In the space of the fixing section; a metal clip hooks together with a stud bolt on the housing; the metal clip has a current conducting plate that presses on the threading of the stud bolt, and the tip of the current conducting plate forming an angle to a radial direction of, and contacting the stud bolt, and is arranged such that its length extends beyond the threading of the stud bolt in an axial direction of the stud bolt. A conductive path is formed among the conductive rubber clamp, the conductive plastic housing and the current conducting plate of the metal clip.
