Plug-in connector
View Patent ↗The invention relates to a plug-in connector ( 10 ) having at least one contact chamber ( 50 ) provided in a plug housing ( 12 ) for receiving a contact element ( 11 ) that provides at least one abutment ( 51, 52 ) for a locating element ( 41 ) arranged on the contact element ( 11 ). The locating element ( 41 ) is designed as an inelastic locating hook ( 41 ). The side wall ( 30, 31 ) of the contact chamber ( 50 ) is resilient, at least in the area before the abutment ( 51, 52 ), Further, a recess ( 36, 37 ) is provided in the plug housing ( 12 ) at least adjacent the resilient area of the side wall ( 30, 31 ).
1. Plug-in connector comprising at least one contact chamber provided in a plug housing for receiving a contact element that provides at least one abutment for a locating element arranged on the contact element, wherein the locating element is designed as an inelastic locating hook, a side wall of the contact chamber is resilient, at least in the area before the abutment, a recess is provided in the plug housing at least adjacent the resilient area of the side wall, the recess comprising an outwardly open hollow opening defined in part by the side wall of the contact chamber, by a first tapered portion provided at a lower end of the side wall and by a second tapered portion provided at an upper end of the side wall, wherein the first tapered portion and the second tapered portion selectively and symmetrically influence the resiliency of the side wall and wherein the resilient area of the side wall is displaced into the recess during a mounting of the contact element into the contact chamber.
2. The plug-in connector as defined in claim 1 , wherein said side wall comprises a first side wall and a second side wall, wherein said first side wall and said second side wall are resilient, at least in the area before the abutments, and wherein said recess comprises a first recess provided in the plug housing at least adjacent the resilient area of said first side wall and a second recess provided in the plug housing at least adjacent the resilient area of said second side wall.
3. The plug-in connector as defined in claim 1 , wherein locating hooks are provided on both sides of the contact element.
4. The plug-in connector as defined in claim 1 , wherein an edge length of a locating area of the locating hook is determined depending on a predefined pull-out force and/or mounting force.
5. The plug-in connector as defined in claim 1 , wherein a maximum projection length of the locating hook is determined depending on a predefined pull-out force and/or mounting force.
6. The plug-in connector as defined in claim 1 , wherein an angle of inclination of a projection of the locating hook is determined depending on a predefined pull-out force and/or mounting force.
