An end fastening part for an energy chain, for connecting to a link plate of a terminal chain link at one end and to a connection point on a system part at the other end. The single-piece end fastening part has a main plane and comprises: an overlapping region having a side wall for connecting to a link plate; a frame-type fastening region having a frame, in which a plurality of fastening holes is provided, for fastening to a connection point; and, therebetween, a transition region, in which a concave end face is provided. According to the invention, the end face has at least two retaining protrusions, which protrude parallel to the main plane and behind which a link plate can engage such that the link plate is retained transversely to the main plane. Furthermore, the overlapping region has at least one, preferably two fixing protrusions, which protrude from the side wall perpendicularly to the main plane, for fixing a connected link plate in position in the longitudinal direction.

A hose retention system for a negative-angle-capable blasthole drilling machine is disclosed. The hose retention system may include an upper cage to extend longitudinally along a mast structure. The upper cage may have a secured end to couple the upper cage to the mast structure, a free end to extend toward the mast structure, and a first longitudinally-extending channel. The hose retention system may include a lower cage separate from the upper cage to extend longitudinally along the mast structure. The lower cage may have a secured end to couple the lower cage to the mast structure, a free end to extend toward the mast structure, and a second longitudinally-extending channel.

A device (10) for monitoring a retraction system (100) includes at least one capacitor (14) connected to at least one spring (12) in such a manner that the connection of the at least one spring (12) and the at least one capacitor (14) forms a tuned circuit (16). A frequency determination component (20) is provided and is designed to determine information regarding a frequency of the tuned circuit (16). An evaluation unit (30) is designed to derive information regarding a length of the at least one spring (12) from the information regarding the frequency of the tuned circuit (16).

A linear motion mechanism has a plurality of linear motion elements assembled telescopically in multiple stages, and a block row connected to the linear motion elements and configured to drive the linear motion elements. A drive mechanism feeds the block row from an accommodating portion to extend the linear motion elements and pulls back the block row to the housing to contract the linear motion elements. The wire body is wired along the block row. A detour member is provided to absorb the excess length of the wire body which varies as the block row is fed and pulled back.

A refrigerator has a wiring mechanism. The refrigerator comprises a cabinet and a drawer-type door body, wherein the cabinet forms a compartment provided with an opening facing forward, and the drawer-type door body is provided with an electrical component. The wiring mechanism comprises a cable for supplying power to the electrical component, and a drag chain for accommodating part of the cable, wherein one end of the drag chain is fixed inside the compartment, and the other end of the drag chain is connected to the drawer-type door body and moves forward and backward along with the drawer-type door body, thereby preventing the cable from being deformed and damaged, and ensuring a reliable electrical connection.

There is provided a supporting member having excellent durability and an apparatus including the supporting member. The supporting member includes an elastic member and a plurality of block members formed thereon. The supporting member is deformable from a shape in which end surfaces of the block members are in contact with each other to a shape in which the end surfaces are separated from each other. The elastic member includes a fixed region whose deformation is restricted by being fixed to a bottom surface of the block member, and the supporting member includes a flexure reduction unit for reducing flexure at a position near the fixed region of the elastic member.

A charging device autonomously charges an electric vehicle. The charging device includes: a main body and an arm coupled to the main body. The main body is controllably moveable, and the arm is controllably extendable and retractable in a longitudinal direction. A charging plug is included at a distal end of the arm. The charging plug is controllably moveable and insertable into a charging portal of the electric vehicle. The arm comprises: a rigid chain, the rigid chain being compliant in a first direction from a neutral axis and resistant in an opposite second direction past the neutral axis, or at least one scissor arm.

Aspects of the technology relate to rotational electromechanical systems, in which data and or power are supplied to components while one part of the system is rotating relative to another part of the system. Repeated rotation may create strain on or otherwise cause the cables to intermittently or permanently fail. A helical cable management system is provided that enables full rotation to the extent permitted. One or more cables are wound in a helical shape around the axis of rotation, which distributes the deformation of the cable along the helical length. Rotation in one direction causes the helix diameter to increase, while rotation in the other direction causes the helix diameter to decrease. A structure is used to maintain the distance between helical turns, while permitting the increase and decrease of the helix diameter. This reduces the overall strain on the cables, which can significantly extend their useful lifetime.

A line guide device for lines in a clean room application, comprising an elongate, flexible envelope which is displaceable to-and-fro between a first connection point and a second connection point movable relative thereto, forming a deflection arc between two runs. The envelope has at least one undoable and reclosable connection region, for insertion or removal of a line when the connection region is open. The envelope, when closed, surrounds in dust-tight manner an inner space for accommodating one or more lines. A functional material is provided within the envelope to reduce the number of free particles in the inner space. The functional material may retain operationally released particles in the inner space and/or counteract the operational release of particles in the inner space.

A power supply mechanism for a long-stroke seat has a wire harness accommodation box having at least one accommodation space and at least one opening; a drag chain bent and accommodated in the accommodation space, where a first end of the drag chain is relatively fixed to the wire harness accommodation box, and a second end of the drag chain passes through the opening and is slidably disposed in a slideway of a lower slide rail of the seat; a wire harness threaded in the drag chain, where a first end of the wire harness passes through a first end of a wire harness channel and the opening to be connected to a power supply, and a second end of the drag chain passes through a second end of the wire harness channel to be connected to an upper slide rail of the seat.
