A utility coupler that includes a coupling unit and a tool unit that can be selectively engaged together. The coupling unit may include a body, a cam member, a handle, and one or more utility couplings. The tool unit may include a body, a latching pin, and one or more utility couplings. In operation, the coupling unit may be placed into a decoupled position with the handle in a first position. The coupling unit may be moved into proximity of the tool unit. The handle may be moved to a second position causing the cam member to engage with the latching pin and couple the coupling unit to the tool unit. The utility couplings engage together to pass the one or more utilities to the industrial equipment.

A drain configured to evacuate leaks of fluid, such as fuel, from a leak collecting system of an aircraft, the drain comprising a rigid tube secured to a plate, the plate being configured to be attached to an external wall of the aircraft, a flexible pipe configured to join the collecting system to the rigid tube, one end of the flexible pipe being received within the rigid tube. The rigid tube comprises a channel, the channel being configured to allow separation of the rigid tube from the plate at the location of the channel.

A single piece structural connector is provided that includes a single machined aluminum piece having first and second circular ends including a plurality of bolt holes and a center hole. The connector also includes an alignment dowel positioned on the center hole. The alignment dowel is configured to tightly fit into a center hole of a pipe plate.

A method of forming an assembly between a panel and a tube includes forming a hole in the panel, where a diameter of the hole is smaller than an outer diameter of the tube, and preforming a first end of the tube to conceal the hole of the panel. A diameter of the preformed portion is greater than the diameter of the hole and the outer diameter of the tube. The method further includes aligning a second end of the tube with the hole of the panel, followed by inserting the tube into the hole by application of axial force on the tube until the preformed first end of the tube abuts a periphery of the hole of the panel. The method also includes achieving an interference fit between the hole of the panel and the tube.

A multi-coupling (1)-couples lines (2) with an alignment aid (5) assigned to a first coupling part (3) and a second coupling part (4) for compensating for offset tolerances during threading of the first coupling part (3) into the second coupling part (4) during coupling of medium couplings (6). At least one coupling part has a coupling carrier (8) mounted floatingly transversely with respect to the coupling direction (7), and the alignment aid (5) has, on one coupling part, a central precentring journal (9) protruding from a coupling carrier in the coupling direction (7) and at least one precision centring journal (11) protruding from the coupling carrier (8) in the coupling direction (7) and arranged radially around the precentring journal axis (10). The precision centering journal head is set back in the coupling direction (7) with respect to the precentring journal head, and the alignment aid (5) has, on the coupling socket side, a central jaw (12) that merges in the coupling direction (7) into a precentring guide (13) for the precentring journal (9) and is equipped with at least one precision centering guide (15), arranged around the precentring guide axis (14), for the precision centering journal (11).

The invention relates to a connector assembly including a plate (10) having an orifice (10a) and a spigot (12), said spigot (12) having an internal flow path for liquid, and connector means (14) for connecting the spigot (12) to the metal plate (10) so as to guide the liquid flowing in the flow path through said orifice (10a), said connector means (14) including a protruding collar structure (16) surrounding said orifice (10a).

It is proposed that the connector means (14) further includes a ring-shaped snap-on module (18) configured to be fitted over the collar structure (16), said snap-on module (18) including a cylindrical insertion part (18a) configured to be inserted into an orifice (10a) of said collar structure (16), wherein a remote end of the cylindrical insertion part (18a) in the insertion direction is provided with first snap-on structures engaging with the collar structure (16).

The invention relates to a connector socket for connecting a spigot (12) to an orifice (10a), said connector socket including a sheet metal plate (10) with said orifice (10a) and a protruding collar structure (16) surrounding said orifice (10a).

It is proposed that the collar structure (16) is integrally made of the sheet metal of said sheet metal plate (10) by a sheet metal forming process.

A plate-type refrigerant pipe includes: a first plate; and a second plate. The first plate and the second plate are joined to form a refrigerant flow path. The first plate includes a first connection portion to which a first refrigerant pipe is connected and that causes the refrigerant flow path to communicate with the first refrigerant pipe. The second plate includes a second connection portion to which a second refrigerant pipe is connected and that causes the refrigerant flow path to communicate with the second refrigerant pipe. One or both of the first plate and the second plate include a third connection portion to which a third refrigerant pipe is connected and that causes the refrigerant flow path to communicate with the third refrigerant pipe.
