The first coupling member has a first coupling formation (16). The load coupling (10) further comprises a second coupling member (14) adapted for operative coupling with the first coupling member (12). The second coupling member (14) includes an attachment formation (15) operatively adapted to attach the second coupling member (14) to a target component to which force generated by the actuator is to be transferred. The second coupling member (14) defines a second coupling formation (24) operatively associated with the first coupling formation (16) of the first coupling member (12). The first coupling formation (16) has (i) a secure orientation relative to the second coupling formation (24) in which the first coupling member (12) is secured to the second coupling member (14) and (ii) a release orientation relative to the second coupling formation (24) in which the first coupling member (12) is adapted to be removed from the second coupling member (14).

A method for making a bayonet connecting element for a connector, according to which a connecting element body, with a hollow cylindrical general shape is made. The method includes making a through bore by drilling a wall of the body of the connecting element, from the outer surface of the wall. The outer surface of the wall is machined around the bore so as to create a conical contact surface around the bore. A lug is inserted into the bore, from the outer surface of the wall, so that a head of the lug projects from the outer surface of the wall of the connecting element. The lug having a conical contact surface corresponding to the conical contact surface of the bore.

A connector assembly may include a body including a first aperture and a second aperture; a rotating member disposed at least partially in the first aperture; and/or a mating member having a portion disposed at least partially in the second aperture. The rotating member may be configured to rotate to limit movement of the mating member.

An installation mechanism of LED lighting includes a house and a mounting plate. The house includes a mounting slot provided on a side wall along a radial direction thereof. The mounting slot includes a implantation portion and a catch portion communicating with the implantation portion. The catch portion includes at least one catching arm provided on one of two opposite side walls thereof. The mounting plate includes two catch edges inserted in the catch portion. The implantation portion is configured for presetting the mounting plate. Each of the catch edge has a Z-typed shape in a cross section of the mounting plate along the axial direction thereof. A free edge of the Z-typed catch edge is inserted into a gap between the catching arm and the bottom of the mounting slot.

An apparatus comprises a panel, a cavity extending into the panel, a plurality of overhangs cantilevered from a perimeter of the cavity and catches resiliently projecting from a portion of a floor of the cavity. The overhangs define an insertion opening for a lock. The catches are oriented respect to the insertion opening such that the catches deflect by a first extent when the lock is positioned at a depth within the cavity below the overhangs and such that the catches deflect by a second greater extent during rotation of the lock to beneath the overhangs.

A cam-lock fastening system is designed to accommodate a tolerance stackup to fasten a pair of rigid structures. A spring allows some longitudinal motion of the pin that would not be accommodated by the rigid structures or metal cam-lock and pin. The spring-loaded pin is also suitably designed to produce a preloaded structural joint that is between specified minimum and maximum loads for any tolerance stackup that is within specification. The fastening of the structures requires no manual adjustment of the pin, and facilitates blind connection of a high-fidelity electrical connector. Further, the described cam-lock fastening system is designed for high performance applications requiring preload forces in the thousands of pounds per square inch.

A fastening arrangement having a fastening element for elastically connecting a bolt-on part to a support part. The fastening element has a head section (7) that transitions into an element shank. An elastomer profile part with a retaining groove which is open radially to the outside, into which a retaining foot of the bolt-on part can engage, is arranged on the underside of the head section. The retaining groove is designed with a groove wall on the head side and a groove wall on the shank side. The elastomer profile part is constructed in at least two parts from an elastomer body arranged on the head section of the fastening element and from a disk element that has at least the shank-side groove wall of the retaining groove. The disk element is also composed of two components, namely the elastomer profile part and the hard component.

Described herein is a retaining pin comprising a tubular outer shaft and a rotatable shaft disposed within the tubular outer shaft. The rotatable shaft is rotatably engaged with the tubular outer shaft. The rotatable shaft can comprise a locking protrusion fixed to an end of the rotatable shaft and that is operable to rotate with rotation of the rotatable shaft. An axis of the tubular outer shaft and an axis of the rotatable shaft are eccentric.

A grooved rotatably fastening structure includes, in top-to-bottom sequence, a head, a shaft connected to the head, and a fastening portion connected to the shaft. The fastening portion has a first groove and a second groove. The first groove is concavely disposed on a lateral surface of the fastening portion and extends upward from a bottom of the fastening portion. The second groove is concavely disposed on the lateral surface of the fastening portion and extends from the first groove transversely or obliquely. The first groove and the second groove are in communication. The rotatably fastening structure enables users to connect two objects together quickly without compromising the structural strength of the two objects and is applicable to thin objects.
