The present invention provides a base electrical box, and an end portion. The end portion is added to the base electrical box to substantially complete the electrical box. The electrical box also includes at least one intermediate portion that is added to complete the electrical box. The at least one intermediate portion is placed between the base electric box and the end portion.

A waterproof unit including: a first waterproof tube that has a tubular shape and is to be attached to a through hole of a vehicle body panel disposed between a waterproof area that requires waterproofing and a non-waterproof area that does not require waterproofing; a second waterproof tube that has a tubular shape and is to be disposed in the non-waterproof area so as to be spaced apart from the first waterproof tube; and a first exterior tube that has a tubular shape, is disposed between the first waterproof tube and the second waterproof tube, and is coupled to the first waterproof tube and the second waterproof tube, wherein the first exterior tube has higher flexural rigidity than the first waterproof tube to be kept from coming into contact with the first waterproof tube when the waterproof unit is bent in the non-waterproof area.

Quick coupling device 1 for transferring liquid for an aircraft, comprising a female member 7 configured to be connected to a first reservoir, said female member 7 forming a passage and comprising a cylindrical portion 13 and a radial portion 14, a male member 2 configured to be connected to a second reservoir, said male member 2 forming a passage, slidably mounted in a liquid-tight manner in the female member 7 and comprising a cylindrical portion 3 and a radial portion 4, and a member 40 for locking the male member 2 in the female member 7, the locking member 40 being disposed between the radial portion 14 of the female member 7 and the radial portion 4 of the male member 2, the locking member 40 surrounding the male member 2 and leaving a limited sliding extent for the male member 2 with respect to the female member 7, engaging with the female member 7 in the locked position and releasing the female member 7 in the unlocked position, the locking member 40 comprising an axial blocking lock that can be actuated by an axial then rotating movement and that can be released by an axial then rotating movement, and a rotation brake, the lock and the brake being active in the locked position.

A device is disclosed with an internal conductor, which is arranged within the tube interior of a tubular metal sheath and is electrically insulated from this sheath with a compacted, electrically insulating material, in which the compacted electrically insulating material is a compacted magnesium oxide granulate made from magnesium oxide grains of different sizes with edges and projections, and that sections, especially edges and projections of magnesium oxide grains are pressed, under local deformation of the internal conductor and/or the tubular metal sheath, into the internal conductor or into the tubular metal sheath. A method for manufacturing such a device is also disclosed.

A line feedthrough for guiding at least one line through a component, contains a cladding tube, at least one element which is mounted within the cladding tube and can rotate relative to the cladding tube, and a sealing element which is in the form of a flexible hose body and arranged within the cladding tube and the element. The hose body is connected, in an axial end region, to the element and can be displaced by rotational movement between a closed position and an open position. A guide element is provided which can be displaced in the longitudinal direction relative to the cladding tube, and which cooperates with a guide track of the element. The guide track of the element is in a spiral shape, such that a displacement of the guide element in the longitudinal direction leads to a rotation of the element relative to the cladding tube.

The presently disclosed technology generally provides a modular support system for plumbing connections. In one example, the system includes a frame, a connector that fits entirely in front of a support stud, and an optional housing. The frame includes symmetrical sides, each including a rail assembly. The connector includes first opposed sidewalls, each having a pair of boxways that receive the rails on any side of a frame unit to form a sliding joint between the frame and connector. Second opposed sidewalls include flexible tabs that engage frame corner flanges to prevent rearward disengagement of the connector from the frame. The housing includes structure for connection with the frame. The housing can be rotated for connection with the frame to receive vertical or horizontal plumbing lines. Connectors can connect the frame units in vertical or horizontal relation, or on either side of a building stud, or to brackets.

A sealing system including a first end and a second end with flexible bellows extending therebetween. The first end includes a base plate with an inner ring having an inner diameter. The inner ring is configured to receive a pipe therethrough. The pipe has an outer diameter, which is smaller than the inner diameter of the inner ring. The bellows of the sealing system has a first length in a first position and second length in a second position. Upon axial expansion of the pipe, the bellows is configured to move from the first position to the second position. The sealing system may also comprise a mechanical protective element, such as a shroud which extends around the bellows. Movement of the bellows can be further limited with rods extending from the shroud to a surrounding substrate or a cable fixing a maximum distance between the pipe and the shroud.

System for providing a conduit sealingly to a through-opening in a plate-shaped construction element so that at least one pipe and/or cable can extend through the conduit and so that after sealing remaining space in the conduit a completely sealed-off pipe and/or cable penetration through the plate-shaped construction element is obtained, wherein the system is such that it is mechanically mountable, wherein the system is further such that it is mountable from only one side of the plate-shaped construction element, by only one worker.
