A positioning fixture including a shielding member and a driving member is provided. The shielding member includes a sliding part slidably connected to a functional module, a guiding part, and a shielding part. The sliding part and the shielding part respectively extend from two opposite ends of the guiding part. The driving member is movably disposed on the functional module corresponding to the shielding member. The driving member includes a base part, a driving part that contacts the guiding part, and a pillar part, which protrudes from the base part and is adapted to pass through the guiding groove. When the functional module is positioned on the circuit board, the base part of the driving member is pushed by the electronic component, and the guiding part is pushed by the driving part, so that the shielding member slides and the shielding part shields a screw hole of the circuit board.

A system and method including a fastener clip, the fastener clip including one or more pairs of laterally offset legs joined at a head portion. The legs form a clip opening at an opposite end of the head portion. The fastener clip also includes a pair of arms coupled to the head portion, the arms being configured to move substantially independently from the pair of legs. The fastener clip also includes a pair of projections each attached at the ends of each of the arms. The projections are configured to engage an opening of a blade over which the fastener clip is configured to be coupled to the blade at least based upon the fastener clip being placed over the blade.

A bolt extender includes a bottom portion defining internal threads and a multi-sided outer surface, an upper shoulder, and a threaded rod projecting upwardly from said upper shoulder.

A spacer assembly for spaceably coupling a first and second component with a threaded connection bolt, each one of the first and second component provided with one or more fitting apertures. The spacer assembly includes a support member, a base member, and a spacer member having resilient friction elements configured to provide an interference fit engagement with a predetermined friction force with a threaded connection bolt, during use.

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

A system and method including a fastener clip including a top portion and a bottom portion. The bottom portion includes a platform, a pair of locking arms and a pair of feet. The pair of locking arms is coupled to the platform via a pair of hinges. The pair of feet is coupled to the locking arms and is being configured to rotate with the locking arms. The feet are configured to be partially inserted into a slot in a doghouse and, based at least on the locking arms being rotated, the feet are configured to rotate into the slot in the doghouse and to couple the bottom portion to the doghouse. The locking arms are configured to be coupled to the platform at the end of the rotation.

Fastener clip including a tub that may be configured to engage and be secured to a slot in a chassis. The tub comprising at least two wings have a top portion and a bottom portion. The at least two wings are attached to the tub along a top portion of each of the wings on opposite sides of the tub. Bottom portions of the wings engage the chassis, securing the tub to the slot. The tub comprises at least two hooks on opposite sides of the tub and located laterally to the wings. The wings are configured to bend in response to the tub being inserted into a rib. The rib has tabs with outside edges to engage the hooks. Each of the tabs on the rib may be tapered to form tapered tabs. At the end of each tab, a retention notch engages the hook on the tub.

A fastener for attaching an element to a support includes a fastening base intended to pass through an opening provided in the support by ways of an axial compression force, a head, and a frustoconical and elastically deformable compression collar. The collar, when compressed, is intended to bear against the support. The collar is connected to the head in a connection region. The compression collar has a first bending region, and at least a second bending region, the first and the second bending regions being configured to deform in a predetermined manner when the fastener is subjected to the axial compression force.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. The pair of inner housing retaining surfaces can engage the pair of cooperating inner housing retaining surfaces, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction in response to the inner housing moving in the Y-direction during insertion of the pin into the pin retaining receptacle. Associated methods are also disclosed.

A cable tray including a pair of generally parallel spaced-apart side rails, each side rail defining a plurality of openings. Rungs extend between the rails at intervals spaced along the rails. Each rung includes at least two side walls. Each rung has opposite open ends generally aligned with respective openings in the side rails. End portions of each rung define a transverse opening. A plurality of snap plug fasteners fastens the rungs to the side rails. Each snap plug fastener includes a main body abutting an outboard surface of one of the side rails. A projection extends through one of the openings in the side rail and into one of the open ends of one of the rungs. The projection includes a barb received in one of the transverse openings in the rung.
