A device which can slide up and down on a chain or cable, can be loosened to attach to the chain or cable, but does not have any parts that come free when the part is loosened. The device includes first and second pieces, each made of structural material, the first and second pieces fitting together at concave and convex surfaces, to form an interlock forms inner surfaces with a through hole of a first shape that can slide along either a cable or a chain.

A hinge is disclosed including a first connecting plate, a second connecting plate, a hinge element rotatably coupling said first and second connecting plates, a first pin coupled to the first connecting plate, wherein said first pin extends through a first end of the hinge element, a locking bracket coupled to the second connecting plate, and a second pin coupled to a second end of the hinge element, wherein said second pin extends through the locking bracket. The hinge optionally includes one or more friction locks, cableways, or cable tabs.

Techniques involve a device which includes an energy chain and a sliding table, the energy chain having a plurality of sliding shoes, each having a sliding surface for sliding on the sliding table. The sliding shoes each have a detection element, which is spaced from the corresponding sliding surface by a wearing layer. The sliding table has a sensor for determining the distance (d) between the sensor and the detection elements.

A multi-conductor flat cable having a width and a thickness includes a plurality of individual conductors arranged side-by-side. The conductors include first and second power conductors, a neutral conductor, and a ground conductor.

A wiring harness which is wired between a car body and a sliding door which slides between a closing position and an opening position so as to open and close a doorway in the car body, the wiring harness includes an external member in which one end is supported rotatably about a perpendicular axis relative to the car body and in which the other end is supported rotatably about a perpendicular axis relative to the sliding door. The external member includes bending portions at a sliding door side and at a car body side respectively in a closing state that the sliding door is disposed in the closing position. The bending portions are bent in opposite directions to each other, and a curvature radius of one of the bending portions is smaller than a curvature radius of the other of the bending portions.
