Plug-and-socket connection for water-cooled, current-bearing lines for tools

Abstract

A plug-and-socket connection for water-cooled, current-bearing lines, in particular, to bipolar, high-frequency current conductors for the induction heating of tools is provided. The plug-and-socket connection allows both the electric circuit for the power supply and the circuit for the cooling water to be rapidly and easily closed by hand, or to be interrupted, for example, for maintenance work. The plug-and-socket connection includes a female element and a male element which contain chambers and ducts opening into the chambers that supply the cooling water. The ducts come into contact with one another when the plug-and-socket connection is in the interconnected position. The chambers are in direct contact with the water tubes, which are provided for supplying the cooling water. The backflow of cooling water occurs via a direct connection between a water tube which supplies the male element with cooling water and another water tube which conveys the cooling water away from the female element. Two contact sockets of an electrical plug-and-socket connection are also fixed in the female element, whilst two contact pins which mate with the contact sockets are fixed in the male element. The contact sockets and contact pins are connected to electrical lines for the power supply. The lines are in turn guided through the water tubes.
