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.

Dependent claims

A plug-and-socket connection for water-cooled, current-bearing lines for bipolar high-frequency current conductors used for the induction heating of tools, comprising:

a female element having a housing;
a chamber disposed within said female element housing;
at least one duct for transporting incoming cooling water opening into said female element chamber;
a water tube connected to said female element chamber, wherein said water tube transports cooling water for cooling the plug-and-socket connection;
a male element having a housing, wherein said male element is operatively connected to said female element;
a chamber disposed within said male element housing;
at least one duct for transporting incoming cooling water opening into said male element chamber, wherein said female element ducts are operatively connected to said male element ducts in the interconnected state of the plug-and-socket connection;
a water tube connected to said male element chamber, wherein said water tube transports cooling water for the plug-and-socket connection;
wherein said male element water tube and said female element water tube are interconnected to provide a backflow of the cooling water between said male element water tube to supply cooling water to said male element and said female element water tube to transport the cooling water away from said female element, such that said interconnection bypasses said female element and said male element chambers;
a contact socket for an electric bipolar plug-and-socket connection mounted in said female element housing, wherein said female element housing includes a bore adjacent to said duct, and said contact socket is disposed within the contact socket bore;
a contact pin of said male element corresponds to said contact socket, wherein said contact pin projects from an end face of said male element housing into a bore in said male element housing adjacent to the ducts;
and
an electric line for supplying power electrically connected to said contact sockets and said contact pins, wherein said electric line is guided therethrough said male and female element water tubes that supply and convey away the cooling water.

A plug-and-socket connection for a current-bearing line comprising:

a female element having a housing;
a chamber disposed within said female element housing;
at least one duct for transporting incoming cooling fluid opening into said female element chamber;
a fluid tube connected to said female element chamber, wherein said fluid tube transports cooling fluid for cooling the plug-and-socket connection;
a male element having a housing, wherein said male element is operatively connected to said female element;
a chamber disposed within said male element housing;
at least one duct for transporting incoming cooling fluid opening into said male element chamber, wherein said female element ducts are operatively connected to said male element ducts in the interconnected state of the plug-and-socket connection;
a fluid tube connected to said male element chamber, wherein said fluid tube transports cooling fluid for the plug-and-socket connection;
wherein said male element fluid tube and said female element fluid tube are interconnected to provide a backflow of the cooling fluid between said male element fluid tube to supply cooling fluid to said male element and said female element fluid tube to transport the cooling fluid away from said female element, such that said interconnection bypasses said female element and said male element chambers;
a contact socket for a plug-and-socket connection mounted in said female element housing, wherein said female element housing includes a bore adjacent to said duct, and said contact socket is disposed within the contact socket bore;
a contact pin of said male element corresponding to said contact socket, wherein said contact pin projects from an end face of said male element housing into a bore in said male element housing adjacent to the ducts;
and
an electric line for supplying power electrically connected to said contact sockets and said contact pins, wherein said electric line is guided therethrough the male and female element fluid tubes that supply and convey away the cooling fluid.
