Problems solved by technology

Since the structure (bush part) inserted into the connector is composed of two parts, one of which is inserted into the inside of the other, the other part becomes relatively complicated
At the same time, it is not possible to confirm the existence of a satisfactory state of engagement by visual observation alone, at least not easily

Embodiment Construction

[0023] figure 1 The bushing part 1 and the inserting part 2 of the plug-in connector of the present invention are shown in an assembled state. The flow cross-section of the insert 2 is continuously connected with the connection port 3 and the outlet 4 .

[0024] figure 2 A longitudinal section of the plug-in connector is shown, from which it can be seen that the locking element 5 engages behind an annular retaining rib 6 integrally formed on the plug-in part 1 , the purpose of which is to form an axial extraction protection. The insert part 2 is centered on the bushing part 1 by means of the cylindrical surface of the bushing part and the insert part, the insert part 2 and the bushing part 1 leading into each other in a central region 19 .

[0025] The insert is sealed by a sealing ring 7 which is clamped radially between the coaxial cylindrical surfaces of the insert 2 and of the bushing 1 . In the assembled state of the inserted connector, annular retaining ribs 8 are us...

Abstract

An insertion coupling which can be used for example for a vacuum line consists of an insertion part and a sleeve part (1), wherein a locking element (5), which can be brought into engagement with a retaining rib of the insertion part, and an actuation element (10) are integrally formed on a housing tab (9) which extends in an arc-shaped manner around a longitudinal axis of the sleeve part (1) and can be elastically deflected radially. A movement of the locking element (5) in a radially outward direction and thus a release of the engaged state between the sleeve part (1) and the insertion part is possible by moving the actuation element (10) in an actuation direction (13). A construction which is particularly simple in design is produced owing to the small number of parts. The sleeve part (1) is provided with a window, by means of which a correct engaged state of the locking element with the retaining rib can be visually checked.

Description

technical field [0001] The invention relates to a plug-in connector according to the preamble of claim 1 . Background technique [0002] Such plug-in connectors are used, for example, on vacuum lines in automotive construction for forming a connection between a tubular plug-in part provided with a circumferential retaining rib and a bush-like connecting body. The insert can be made of plastic or metal and is located at the end of the connection on the tubing or housing. The connecting body is usually made of plastic and is mounted on the line, but can also be an element of the housing. [0003] Such a plug-in connector has a locking mechanism acting between the connecting body and the plug-in part, which in each case acts as a sealed connection between the line elements to be connected. Such plug-in connectors are available in numerous forms, notably functional reliability and operational orientation considerations in relation to assembly. [0004] DE4300037C1 discloses a...
