Round plug connector comprising a shield connection
The invention relates to a round plug connector for detachably connecting lines, comprising at least one housing element for receiving at least one insulating body and at least one locking element for detachably connecting to a counter plug connector. The housing element also receives at least one circumferential spring element. The spring element is produced for connecting an electromagnetic shield made from an electrically conductive material and has at least one ring retained in a circumferential recess in the housing element and at least one substantially axial wing.
1. A round plug connector ( 1 ) for detachably connecting lines, comprising:
a housing element ( 2 ) for receiving an insulating body ( 3 ) and at least one locking element ( 4 ) for detachably connecting to a mating plug connector ( 5 ),
wherein the housing element ( 2 ) receives a circumferential spring element ( 6 ),
wherein the spring element ( 6 ) is made of an electrically conductive material for connecting an electromagnetic shield,
wherein the spring element ( 6 ) comprises
a ring ( 8 ) held in a circumferential recess ( 7 ) of the housing element ( 2 ) and
a substantially axially extending wing ( 9 ),
wherein the spring element ( 6 ) has a number of wings ( 9 ) identical to a number of locking elements ( 4 ), the number being greater than or equal to two, and
wherein the wings ( 9 ) of the spring element ( 6 ) and the locking elements ( 4 ) alternate circumferentially at the circumference of the housing element ( 2 ).
2. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the wing ( 9 ) is oriented against a plug-in direction (RS) of the round plug connector ( 1 ), so that the ring ( 8 ) points in a direction of the mating plug connector ( 5 ).
3. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the wing ( 9 ) has a concave curvature which extends substantially outside an imaginary cylinder a base of which is formed by an inner diameter (d I ) of the ring ( 8 ).
4. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the wing ( 9 ) has a concave curvature, of which a maximum deflection is substantially outside an imaginary cylinder a base of which is formed by an outer diameter (d A ) of the ring ( 8 ).
5. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the spring element ( 6 ) is electrically conductively connected to the housing element ( 2 ) through the ring ( 8 ) and is electrically conductively connected to the mating plug connector ( 5 ) with a deflection of the wing ( 9 ).
6. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the spring element ( 6 ) is electrically conductively connected to the housing element ( 2 ) through the ring ( 8 ) and an end region of the wing ( 9 ) and is electrically conductively connected to the mating plug connector ( 5 ) with a deflection of the wing ( 9 ).
7. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the wing ( 9 ) is arranged on the ring ( 8 ) deformed by at least 60° against a plug-in direction (RS).
8. The round plug connector ( 1 ) as claimed in claim 1 ,
wherein the spring element ( 6 ) is arranged in a recess ( 7 ) in the housing element ( 2 ), and
wherein the ring ( 8 ) is inserted in a further recess ( 7 ′) in the housing element ( 2 ).
