Electrical plug connector
View Patent ↗The invention relates to a plug comprising a plurality of contact elements located in a plug housing and strain relief elements ( 200, 200′ ) arranged on the housing ( 110, 310 ), wherein both contact elements and strain relief elements can be fixed to a printed circuit board ( 10 ) using SMT technology. The invention is characterized in that the strain relief elements ( 200, 200 ′) are sheet metal elements that can be fixed to parts of the plug housing and are bent essentially at a right angle on the side facing the printed circuit board ( 10 ), thereby forming a bearing surface ( 220, 220′ ) for SMT attach.
1. Plug comprising a plurality of contact elements arranged in a plug housing and strain relief elements arranged on the housing, wherein the contact elements and the strain relief elements can be fixed to a printed circuit board using SMT technology, wherein the strain relief elements are sheet metal elements that can be fixed to parts of the plug housing and are bent off substantially at a right angle on the side facing the printed circuit board, thereby forming a supporting surface for SMT fastening, wherein the sheet metal elements are fastened to webs used for reverse polarity protection, wherein the webs protrude beyond the plug housing both in the mating direction and also transversely to the mating direction, wherein the sheet metal elements can be fixed by latching connections to the webs, wherein the sheet metal elements comprise four latching connections, which are subdivided into two groups of two latching elements each, and wherein the first group is arranged as close as possible to the upper side of the plug and the second group as close as possible to the printed circuit board.
2. Plug according to claim 1 , wherein the sheet metal elements which are bent off at a right angle and form the strain relief elements form a rectangular supporting surface which extends perpendicularly to the mating direction and parallel to the printed circuit board protruding beyond the sides of the housing.
3. Plug according to claim 1 , wherein the sheet metal elements forming the strain relief elements are bent punched parts.
