Connector elements belong to a line or to a plug connector. Shielding sleeves or shielding housings of the lines and/or of the plug connectors are surrounded by a shielding housing, which consists of a cast metal body that has been cast in situ onto annular regions of the shielding sleeves or shielding housings in order to produce a local anchoring means with low electric contact resistance. ## Claims ### Claim 1 A shielded, electrical connector, comprising: one or several conductor elements belonging to at least one line, an intermediate insulation of temperature-resistant, electrically insulating material, disposed at least partially over the one or several conductor elements, one or several shielding sleeves belonging to the at least one line, a shielding housing connecting the one or several shielding sleeves, wherein the shielding housing includes an in-situ cast metal body, which has been cast in situ from liquid metal or liquid metal alloy and disposed directly on and around and in contact with the intermediate insulation, which protects the conductor elements during the casting process of the shielding housing, and onto annular regions of the one or several shielding sleeves, wherein the in-situ cast shielding housing is formed for establishing an anchoring means having a low electric contact resistance and effecting a closed and complete shielding of the connector, and an electrically insulating protective shell around the shielding housing. ### Claim 2 (depends on 1) The connector as claimed in claim 1, wherein one of the conductor elements is on protective earth, and the shielding housing is electrically connected with the protective earth using a cast branching. ### Claim 3 (depends on 1) The connector as claimed in claim 1, formed as a multiway terminal block for one or several shielded lines, comprising: a distributing body with several connection points for the conductor elements that belong either to one or several lines, said intermediate insulation that surrounds the distributing body and conductor elements adjacent thereto. ### Claim 4 (depends on 3) A method for producing the connector set forth in claim 3, namely formed as a multiway terminal block, the connector connecting one or several shielded lines and/or one or several shielded plug connectors with one another, the method comprising the steps of: a) baring a shielding sleeve and conductor elements at the end of the shielded line or lines to be connected, and/or providing the shielded plug connector or connectors, each having a respective shielding plug housing and respective plug conductor elements, b) connecting the conductor elements or plug conductor elements with a distributing body, c) applying an inner intermediate insulation on the conductor elements bared, or on the plug conductor elements bared, and around the distributing body, d) casting liquid metal or liquid metal alloy around the inner intermediate insulation and the shielded sleeve bared when a shielded line is to be connected and/or onto an edge area of the shielded plug housing when a shielded plug connector is to be connected, for forming a shielding housing. ### Claim 5 (depends on 1) The connector as claimed in claim 1, wherein the electrically insulating protective shell is an injection molded plastic shell. ### Claim 6 (depends on 1) The connector as claimed in claim 1, wherein the shielding housing includes a low melting metal alloy. ### Claim 7 (depends on 6) The connector as claimed in claim 6, wherein the metal alloy is a tin solder. ### Claim 8 (depends on 1) A method for producing the connector set forth in claim 1, the connector connecting a first shielded line with a second shielded line, the method comprising the steps of: a) baring shielding sleeves and the conductor elements at the ends of the first and of the second lines, b) connecting the bared ends of the conductor elements with one another, c) applying the intermediate insulation on the bared ends of the conductor elements, which are connected with one another, d) casting liquid metal or liquid metal alloy around the intermediate insulation and the bared shielding sleeves for forming the shielding housing. ### Claim 9 (depends on 8) The method as claimed in claim 8, wherein step d) includes injection molding the electrically insulating protective shell around the shielding housing. ### Claim 10 (depends on 1) A method for producing the connector set forth in claim 1, the connector connecting conductor elements of a shielded line with contact elements of the connector, the method comprising the steps of: a) baring a shielding sleeve and the conductor elements at the end of a shielded line, b) applying contact elements at the end of the conductor elements and insulating the contact elements from one another by means of an insulating connector housing, c) applying the intermediate insulation on conductor elements that have bared ends, and d) casting liquid metal or liquid metal alloy around the intermediate insulation and the bared shielding sleeve for forming a shielding housing. ### Claim 11 (depends on 1) The method as claimed in claim 1, wherein the intermediate insulation is an injection molded plastic intermediate insulation. ### Claim 12 A method for producing a connector, comprising the steps of: a) connecting bared ends of conductor elements with one another, b) applying an intermediate insulation on the bared ends of the conductor elements connected with one another, c) casting in situ liquid metal or liquid metal alloy to form a cast metal body, around and in contact with the intermediate insulation, and around and in contact with one or several shielding sleeves once bared and/or one or several shielding housings for forming an in-situ cast shielding housing, wherein the in-situ cast shielding housing is formed for establishing an anchoring means having a low electric contact resistance and effecting a closed and complete shielding of the connector; and d) surrounding the shielding housing with an electrically insulating protective shell. ### Claim 13 (depends on 12) The method as claimed in claim 12, insofar as shielded lines are concerned, wherein each a soldered connection between a shielding housing and a shielding sleeve or sleeves of the shielded lines is provided by partially fusing metal at the shielding sleeve in question.
