Embodiment Construction

[0020] figure 1 Shown is a male plug part 1 and a female coupling part 2 that produce a bayonet-type connection with low force consumption, which also prevents accidental loosening of the connection. The housing 22 of the female engaging part 2 is provided with a curvilinear, preferably J-shaped stop groove 4 , and the male plug part 1 is provided with a corresponding stop protrusion 3 . A groove is provided upstream of the locking projection 3 , in which groove an elastic sealing ring 5 , for example an O-ring made of temperature-resistant EPDM, is seated. The stop protrusion 3 on the male plug 1 is consistent with the stop groove 4 on the female engaging part 2 . The compression spring 6 is arranged in the housing 22 of the female coupling part 2 .

[0021] The locking groove 4 has a preset end position 18 ( figure 1 ), the stop lug 3 rests on this end position, which prevents an unintentional opening movement. As a result, a permanently reliable connection can be produc...

Abstract

The invention relates to a plug connector, in particular a plug connector having a high level of electrical insulation. The plug connector was to be developed such that a mechanically stable and tight plug connection can be achieved, which additionally allows a quick and easy connection and disconnection even in harsh industrial environmental conditions. For that purpose the plug connector comprises a male plug part (1) and a female coupling part (2), wherein the male plug part (1) has a catch mechanism (3) on the circumferential surface and a locking groove (4) is provided on the female coupling part (2) to produce a bayonet-type plug connection. Here, an annular seal (5) is provided either on the circumference of the male plug part (1) ahead of the catch mechanism (3) or on the inner circumference of the female coupling part (2) shifted back with respect to the catch mechanism (3). When the plug connection is closed, the annular seal rests, exerting a sealing force, between the circumference of the male plug part (1) and the inner circumference of the female coupling part (2).

Description

technical field [0001] The invention relates to a plug connector, especially a plug connector with high electrical insulation, which is suitable for industrial use under severe environmental conditions. The plug connector has a male plug and a female fitting, wherein the male plug is provided with a stop protrusion on the circumferential surface, and has a bayonet plug connection for establishing a bayonet plug connection in the housing of the female fitting. stop groove. Background technique [0002] Plug connectors are used in various fields of electrical technology, for example in industrial multi-channel measuring technology. Plug connectors must meet different usage standards. [0003] Threaded plug connectors are known, in which a nut is screwed onto a mating part with an external thread. It is very laborious to loosen and connect, and the closed state cannot be checked clearly and simply. SMC-plug connectors with screw locks are very susceptible to harsh environme...
