Embodiment Construction

[0021] In FIG. 1 , the combination shown comprises a line 10 and a sealing cap 14 on the end 12 of said tube 10 . The sealing cap 14 has an approximately pot-like shape, the housing 16 of which forms a tubular or sleeve-shaped connecting part in the sense of the invention. The end 12 of the tube 10 forms a further tubular or sleeve-shaped connection within the meaning of the invention. The end 12 of the tube is designed on its outer circumference with two diametrically opposite, radially protruding locking projections 18 , as can also be seen in FIG. 2 . A circumferentially inclined upper punch surface 20 is formed on each locking projection 18 , which runs obliquely relative to the circumferential direction when viewed in axial section. The circumferentially inclined upper punching surfaces 20 on the two locking protrusions 18 face the same direction.

[0022] Figures 3 and 4 show two locking gaps (locking recesses) 22 molded into the housing 16 of the sealing cap 14, diame...

Abstract

The invention proposes a combination of two bodies with a tubular or sleeve-shaped connecting portion, which can be inserted into each other, and which constitute a component of an aircraft air-conditioning piping system. In said combination, the first body (10a) has at least one radial locking protrusion (18a) on its connecting portion (12a) and the other second body (28a) has at least one radial locking protrusion (18a) on its connecting portion (30a). Locking gap (22a) completely surrounded by an edge. The at least one locking protrusion and the at least one locking gap are configured and cooperate with each other such that in the relative locking rotational position of the two bodies, each locking protrusion engages the associated locking recess while simultaneously fixing the two bodies against axial pullout of each other.

Description

technical field [0001] The invention relates to a combination of two bodies with a tubular or sleeve-shaped connecting part, which can be inserted into each other, which constitutes a part of an aircraft air-conditioning line system. Background technique [0002] When assembling aircraft air conditioning piping systems, due to the length of the piping system and the numerous connection points that go with it, there is a need for an easy and secure way of interconnecting adjacent elements of the piping system that can be inserted into each other. It is known in practice to connect two line elements that are pushed into each other by means of an externally fitted entrainment. The assembly of the entrainment and its removal during disassembly are quite laborious operations for the assembler. Such entrainment also implies additional material costs. [0003] US 1,033,187 discloses a method of connecting two hose-like or duct-like bodies by means of a locking protrusion, wherein...
