An electrical connector including a mounting flange defining a mounting hole extending therethrough that is configured to receive a threaded fastener and a deformable crush rib extending from the mount flange and surrounding the mounting hole is presented herein. A method of assembling an electrical connector to a panel including the steps of inserting a fastener within a mounting hole of a mounting flange defining the mounting hole extending therethrough and a crush rib surrounding the mounting hole, applying a clamping force to the mounting flange via the fastener, and deforming the crush rib via the clamping force applied by the fastener such that the deformed crush rib at least partially fills a gap between an inner wall of the mounting hole and the fastener is also presented herein.

A heavy-duty, harsh environment coaxial connector assembly includes a mounting shell connector including a cylindrical body and an electrically conductive mounting flange extending from the cylindrical body, a plurality of mounting apertures formed in the flange to support the mounting shell connector via a plurality of fasteners extending through the respective mounting apertures, and wherein each of the plurality of fasteners is electrically isolated from the mounting flange.

A ceiling fan motor housing includes a bottom cover member, a hollow housing member, and a plurality of screws. The bottom cover member is formed with a plurality of threaded holes. The housing member is formed with a plurality of L-shaped positioning members extending from a bottom end thereof. Each of the positioning members has a vertical portion which is connected to the bottom end of the housing member and a horizontal portion which extends inwardly from a bottom end of the vertical portion, supports the bottom cover member, and is formed with a positioning hole. The screws respectively extend through the positioning holes of the positioning members to respectively engage the threaded holes of the bottom cover member.

A flange arrangement includes a power shaft, a flanged hub connected detachably to the power shaft, and a stop member configured to detachably hold the flanged hub on the power shaft and to exert a disassembly force on the flanged hub so as to be able to rotate about a rotation axis of the power shaft.

An anchor assembly for insertion in a panel aperture in a receiving panel has a flange. The flange has an engagement surface locatable on a first side of the receiving panel. A plurality of resilient arms project from the engagement surface and are insertable in the panel aperture. At least two of the plurality of resilient arms define a channel therebetween for receiving a threaded fastener. The channel is sized to limit inward deflection of the at least two of the plurality of resilient arms when the threaded fastener extends within the channel. A threaded surface is located in the flange and forms at least in part an anchor aperture for alignment with the panel aperture. The channel is aligned with the anchor aperture. The threaded surface is located between the plurality of resilient arms and is adapted for threadingly engaging the threaded fastener.

A thimble assembly for a cyclone separator comprising a plurality of mounting brackets separately mountable on a shelf of the separator along the perimeter of an exhaust opening, a plurality of segments vertically successively suspended from the brackets, the segments of an upper row being joined to the brackets, the segments of each successive lower row being joined to the segments of a row immediately above, each bracket exclusively serving a chord of an arc concentric with the preferably circular opening that is substantially the same in length as the chord of an arc that a segment spans, a center-to-center chordal spacing of adjacent brackets being the same as a center-to-center distance of an adjacent pair of segments.

A fastener structure includes a head portion, a body portion and an elastic element. The head portion has a shaft section, a press section and a hold-down section. The body portion has a corresponding press section, which is movably assembled to the press section. The elastic element has an end pressed against the press section and another end against the body section, allowing the head portion to move elastically. The body portion can be engaged with an object, and the hold-down section of the head portion can elastically hold down a workpiece against the object or be elastically removed from the workpiece, so as to complete the connection and disconnection of at least two objects to and from one another in a quick and repeatable manner.

Segments are linked in the circumferential direction to assemble a pipe unit. A link bolt is used to link the segments of the pipe unit in the longitudinal direction to assemble a rehabilitation pipe inside an existing pipe. An elastically deformable hollow cylindrical member having a tongue is attached to the link bolt between the inner plates. The outer diameter of the cylindrical member is larger than the insertion hole of the inner plate through which the link bolt can pass. This allows the link bolt to be prevented from falling out of the segment when the link bolt moves in the longitudinal direction due to gravity. When a force is applied to the tongue from below, the cylindrical member is elastically deformed and can be removed from the link bolt.

A cover band has a cover band body provided with a cover band arch portion corresponding to the outer peripheral surface of a steel pipe strut and a plurality of cover band through holes formed on the cover band body in such a manner as to correspond to a plurality of strut coupling holes. The cover band through holes have shapes of long holes extended in one direction and the extended direction of at least one of the cover band through holes is made to cross the extended direction of the other cover band through hole.

A connection node assembly for use in connecting an upper prefabricated building module to a lower module. Hollow vertical edge supports of the building modules have top and bottom connection parts. A connecting bolt can be passed through the top part of an upper vertical support in the upper building module and seated within the bottom part of that vertical support with the shank extending downward. The shank engages a threaded aperture in a connecting nut secured within the top part of a corresponding lower vertical support in the lower building module. Diaphragm plates sandwiched between the upper and lower vertical supports are used to tie horizontally placed modules together.
