A system and process for removably, replaceably, and fixedly coupling a member to a structure without the need for adhesives or welding. The member is provided with an insert coupling that makes use of reciprocating catches in the mating region of the insert coupling. The reciprocating catches engage receiving features provided in a hollow end of the structures to couple the structure to the member via the insert coupling. The structure can be uncoupled from the member by disengaging the reciprocating catches of the insert coupling from the receiving features of the hollow end of the structure.

An appliance and fastening assemblies therefore are provided. A method of mounting an object to a part of an appliance using a fastening assembly is also provided. In one aspect, a fastening assembly of an appliance includes a wall defining an engagement hole. The fastening assembly also includes a tab connected to the wall and defining a clearance hole. The tab is folded over onto the wall such that the clearance hole is in communication with the engagement hole. A fastener of the fastening assembly has a head and a shank extending from the head. The shank has threads along at least a portion of the shank. The shank of the fastener is received through the clearance hole and the engagement hole. When the fastener is torqued or driven, a portion of material of the wall is extruded into the clearance hole of the tab.

A double shear attachment device with an eccentric axis and eccentric sleeves, mechanical assembly including such a device and assembling process. The attachment device comprises an eccentric axis and two eccentric sleeves to mount on the eccentric axis to correct, by an appropriate positioning in rotation of the eccentric sleeves on the eccentric axis, the possible clearances between superposed circular holes of mechanical components that have to be linked together by the attachment device, the attachment device including also blocking structure configured to block in rotation the eccentric sleeves, the attachment device thus allowing to generate a quick and clear attachment, that is able to correct clearances locally.

This nut (1) comprises a nut main body (3) having a substantially cylindrical shape and constituted by a plurality of nut segments (3a), an outer cover (4), a restraining ring (5), an inner cover (6) comprising a restraining plate (6a) at one end portion of the inner cover (6) and serving to cover an outer circumference of the nut main body (3), and a ring-shaped spring (7) serving to bias the nut main body (3) to cause the nut main body (3) to expand radially. Protrusions (8) protruding in a circumferential direction are formed on an inner surface of the inner cover (6). Grooves (9) are formed on an outer surface of the nut main body. The protrusions (8) and the grooves (9) have slant surfaces (10) that contact each other on the same side in the axial direction.

The object is to provide a wire gripper that can withstand a high load acting on a lever member of the wire gripper and a method of using the wire gripper. The wire gripper can achieve the object by including: a wire gripper body; a swing member connected to the wire gripper body swingably about a first axis; a lever member connected to the swing member swingably about a second axis; a first pin member inserted through the swing member and the lever member and arranged along the second axis; a reinforcement member configured to be screwed with the first pin member and reinforce the swing member; and a stopper configured to restrict a position of the reinforcement member in a direction along the second axis.

The invention relates to an insert for connecting an electrical connector to a wall (9) and to a corresponding method. The insert comprises an electrically conductive bolt (1) having a head (3), which extends along a first longitudinal axis (I), and a shaft (4), which is provided with at least one connecting means (5), and a ring (2), which has a through-opening (7) and extends along a second longitudinal axis (II). The head (3) comprises an outer contour which, at least in regions, is produced by the rotation about the first longitudinal axis (I) of a first line (L1), which is curved with a first radius (R1) and spaced apart from the first longitudinal axis (1). The through-opening (7) comprises an inner contour which, at least in regions, is produced by the rotation about the second longitudinal axis (II) of a second line (L2), which is curved with a second radius (R2) and spaced apart from the second longitudinal axis (II).

The present disclosure relates to a drive screw for connecting a carrier formed of foamed material to a part to be affixed to the carrier. In one implementation, the drive screw includes a threaded pin with a first end having shaped elements configured to connect to a tool that transfers torque and a second end configured to penetrate into the carrier. In addition, the first end of the threaded pin may be surrounded by and connected to an interlock component, and the part to be affixed may have an interlock receiving space corresponding to the interlock component.

Disclosed herein is an integrated bonding mid clamp device for solar panel mounting and grounding, as well as a related system and method. The integrated bonding mid clamp includes a deformable toothed washer for breaking an anodized layer of a solar panel frame. The deformable toothed washer is capable of deforming to avoid obstructing proper contact between the mid clamp and the solar panel frame.

A bolt catcher and extractor for use with a separation nut and an attaching preloaded bolt that secure a payload to a launch vehicle or spacecraft. The bolt catcher extracts the attaching bolt from the separation nut, pulls it clear of the interface between the launch vehicle or spacecraft and the released payload, and captures it within the bolt catcher housing. The released bolt may have kinetic energy due to the strain energy stored by the pre-release bolt preload. The bolt catcher may have a magnetic eddy current damper that controls the bolt velocity during bolt extraction and dissipates the bolt kinetic energy as heat. The bolt may be magnetically non-impact captured within the bolt catcher. Bolt momentum at the end of the bolt extraction is less than 2% of that of bolt catchers of the prior art. Shock to the released payload or deployable equipment is near zero.

A deformable insertion fastening arrangement for insertion into a planar ply structure and for retention thereon by subsequent deformation, including a retention component having a passthrough opening passing through it along a passthrough axis and having a fastening configuration for fastening a further component thereonto; the retention component having at least two portions that are radially displaceable relative to the notional passthrough axis that passes centrally through the passthrough opening, the retention component, when considered in its undeformed initial state, is embodied segmentedly in a circumferential direction around the passthrough axis; at least two segments, constituting the radially displaceable portions, being connected to one another by at least one connecting configuration deformable in a circumferential direction; at least one segment being displaceable in a radial direction away from the passthrough axis against a shape inertia force of the at least one connecting configuration, accompanied by enlargement of the passthrough opening.
