Two concentrically arranged housing parts are connected to one another via a base on the end opposite the at least one insertion opening. Between the housing parts, an annular intermediate space is formed as an annular receiving opening for the plug extension of a complementary plug connector. A receiving space for the contact carrier is provided inside the internal housing part. ## Claims ### Claim 1 An electrical plug connector, comprising a housing with at least one insertion opening for a complementary plug connector and a contact carrier inserted into the housing and designed as an insertion part, for the electrical contacts accessible through an insertion opening, wherein the housing has two housing parts that are arranged concentrically and overlap one another in a longitudinal direction, wherein a base connects the housing parts on an end opposite of at least one insertion opening, and wherein an annular intermediate space between the housing parts forms an annular receiving opening for a plug extension of a complementary plug connector, wherein a receiving space for the contact carrier is formed inside an inner housing part at a level of overlap of the housing parts and formed by a cylindrical volume inside the inner housing part, and the contact carrier extends into a longitudinal section of the inner housing part abutting on an inner side, which overlaps with an outer housing part, further comprising a mounting flange projecting radially from the outer housing part, the mounting flange is positioned on an insertion-side end of the outer housing part. ### Claim 2 (depends on 1) The plug connector as claimed in claim 1, wherein guide structures are formed between an inner wall of the inner housing part and the contact carrier. ### Claim 3 (depends on 1) The plug connector as claimed in claim 1, wherein at least one stop is provided for the contact carrier on the inner side of the housing. ### Claim 4 (depends on 1) The plug connector as claimed in claim 1, wherein the contact carrier is configured for XLR contacts. ### Claim 5 (depends on 1) The plug connector as claimed in claim 1, wherein the contact carrier is configured for contacts for data plugs, in particular RJ45 plugs. ### Claim 6 (depends on 1) The plug connector as claimed in claim 1, further comprising a connecting mechanism located between the contact carrier and the housing. ### Claim 7 (depends on 6) The plug connector as claimed in claim 6, wherein the connecting mechanism is configured as a latching and/or snap connection. ### Claim 8 (depends on 1) The plug connector as claimed in claim 1, wherein a seal covers a front side of the mounting flange and has at least one through hole corresponding to the insertion opening. ### Claim 9 (depends on 8) The plug connector as claimed in claim 8, wherein a front plate covers the front side of the mounting flange and the seal. ### Claim 10 An electrical plug connector, comprising a housing with at least one insertion opening for a complementary plug connector and a contact carrier inserted into the housing and designed as an insertion part, for the electrical contacts accessible through an insertion opening, wherein the housing has two housing parts that are arranged concentrically and overlap one another in a longitudinal direction, wherein a base connects the housing parts on an end opposite of at least one insertion opening, and wherein an annular intermediate space between the housing parts forms an annular receiving opening for a plug extension of a complementary plug connector, wherein a receiving space for the contact carrier is formed inside an inner housing part at a level of overlap of the housing parts and formed by a cylindrical volume inside the inner housing part, and the contact carrier extends into a longitudinal section of the inner housing part abutting on an inner side, which overlaps with an outer housing part, further comprising a locking mechanism for a complementary plug connector, wherein at least one locking element is arranged on the contact carrier, wherein an unlocking element protrudes from the locking element through recesses in the housing and a front plate on a front side of the housing and/or the front plate. ### Claim 11 (depends on 10) The plug connector as claimed in claim 10, further comprising a seal with an integrally formed dome for accommodating the unlocking element, the dome protrudes forwards and protrudes through the front plate beyond its front side. ### Claim 12 An electrical plug connector, comprising: a housing with at least one insertion opening for a complementary plug connector and a contact carrier inserted into the housing and designed as an insertion part, the housing has two housing parts that are arranged concentrically and overlap one another in a longitudinal direction; a base connecting the housing parts on an end opposite of at least one insertion opening; an annular intermediate space between the housing parts form an annular receiving opening for a plug extension of a complementary plug connector; a receiving space for the contact carrier is formed inside an inner housing part at a level of overlap of the housing parts and formed by a cylindrical volume inside the inner housing part; and the contact carrier extends into a longitudinal section of the inner housing part abutting on an inner side, which overlaps with an outer housing part, further comprising a mounting flange projecting radially from the outer housing part, the mounting flange is positioned on an insertion-side end of the outer housing part. ### Claim 13 (depends on 12) The plug connector as claimed in claim 12, wherein a stop is provided on an inner side of the housing. ### Claim 14 (depends on 12) The plug connector as claimed in claim 12, further comprising a seal with an integrally formed dome. ### Claim 15 (depends on 12) The plug connector as claimed in claim 12, further comprising a locking element. ### Claim 16 (depends on 12) The plug connector as claimed in claim 12, further comprising a connecting mechanism located between the contact carrier and the housing. ### Claim 17 (depends on 16) The plug connector as claimed in claim 16, wherein the connecting mechanism is a latch or snap configuration. ### Claim 18 An electrical plug connector, comprising: a housing with at least one insertion opening for a complementary plug connector and a contact carrier inserted into the housing and designed as an insertion part, the housing has two housing parts that are arranged concentrically and overlap one another in a longitudinal direction; a base connecting the housing parts; an annular intermediate space between the housing parts form an annular receiving opening; a receiving space for the contact carrier formed on inside an inner housing part; and the contact carrier extending into a longitudinal section of the inner housing part abutting on an inner side, further comprising a mounting flange projecting radially from an outer housing part, the mounting flange is positioned on an insertion-side end of the outer housing part.
