Plug part and socket part for detachably connecting a tube elbow of a gas-cooled welding torch to a hose packet, and connecting device with such a plug part and socket part

摘要

A plug part for detachably connecting a torch neck of a gas-cooled welding torch to a socket part disposed on a hose package includes a cylindrical pipe element with a flange and with an axially extending channel for a welding wire and for a protective gas and includes a union nut which is rotatably disposed on the pipe element and which includes an inner thread for connection to a corresponding outer thread on the socket part. To produce an optimal connection between the torch neck and the hose package, a bevel is disposed on the flange of the pipe element of the plug part, and the end piece of the socket part has at least one axial slot.

1. A plug part for detachably connecting a torch neck of a gas-cooled welding torch to a socket part arranged on a hose package, said plug part having a cylindrical pipe element with a flange and an axially extending channel for a welding wire and a protective gas, and a coupling nut rotatably arranged on the pipe element, said coupling nut having an inner thread for connection to a corresponding outer thread on the socket part, wherein a bevel is disposed on the flange of the pipe element, wherein the bevel is oriented inwardly, wherein at least one receiving opening for receiving a resiliently mounted pin-like element of the socket part is arranged on the flange of the pipe element in order to fix at least one reference angular position of the torch neck, wherein the at least one receiving opening is formed by a bore, wherein the resiliently mounted pin-like element has a substantially hemispherical end,
wherein the resiliently mounted pin-like element is adapted to deflect from the at least one receiving opening by loosening the coupling nut without opening the coupling nut completely and twisting the torch neck and wherein the torch neck is adapted to be fixed in a plurality of angular positions in which the resiliently mounted pin-like element does not project into any of the at least one receiving opening by tightening the coupling nut, such that the torch neck is fixable in a plurality of angular positions other than the at least one reference angular position.
