Abstract

A contact system for plug-in connections on electronics housings ( 1 ) for making contact with mechatronic components of motor vehicles, includes at least one contact element ( 13 ) formed of a punched part, with which contact is made on a printed circuit board ( 5 ) and which is routed out of a housing ( 2 ). For the purpose of making releasable contact with the mechatronic components, flexibly compensating for relative movements of the contacts, and allowing cost-effective production and processing without the use of special technical apparatuses, the at least one contact element ( 13 ) is designed to be fastened to a base plate ( 2 ) of the electronics housing ( 1 ) by insertion and latching, make contact with a plug-in contact ( 23 ) of a mechatronic component by way of a first contact lug ( 14 ), and make contact with the printed circuit board ( 5 ) by way of a second contact lug ( 20 ).

wherein a first pair of latching projections ( 17 a , 17 b ) extending away from the contact projections ( 16 a , 16 b ) are arranged on the first contact lug ( 14 ).

2. The contact system as claimed in claim 1 , wherein the at least one connecting web ( 18 a , 18 b ) is arranged in a zigzag manner between the first contact lug ( 14 ) and the second contact lug ( 20 ; 20 a , 20 b ).

3. The contact system as claimed in claim 1 , wherein the second contact lug ( 20 ) is formed from two parallel contact tabs ( 20 a , 20 b ) which are bent away through 90.degree., and a latching area ( 22 ) is arranged between the two contact tabs ( 20 a , 20 b ) and a second pair of latching projections ( 21 a , 21 b ) extending away from the two contact tabs ( 20 a , 20 b ) are arranged on the second contact lug ( 20 ; 20 a ; 20 b ).

4. The contact system as claimed in claim 1 , wherein the second contact lug ( 20 ; 20 a , 20 b ) is configured to make contact with the printed circuit board ( 5 ) by pressing-in or soldering.

5. The contact system as claimed in claim 3 , wherein the base plate ( 2 ) comprises a contact holder ( 9 ) for receiving the first contact lug ( 14 ) of the contact element ( 13 ), the contact holder being arranged on a face of the base plate ( 2 ) which is opposite to an insertion bevel ( 8 ) for the plug-in contact ( 23 ), a first pull-out prevention element ( 10 ) is arranged on the base plate ( 2 ) adjacent to the contact holder, a third pair of latching projections ( 25 , 26 ) of the pull-out prevention element extending over the latching projections ( 17 a , 17 b ) on the first contact lug ( 14 ), and a second pull-out prevention element ( 12 ) with at least one latching catch ( 12 a ) formed on the base plate ( 2 ) for retaining the second contact lug ( 20 ; 20 a , 20 b ) of the contact element ( 13 ), the latching catch extending over the latching area ( 22 ) on the second contact lug ( 20 ; 20 a , 20 b ).

6. The contact system as claimed in claim 5 , wherein the first contact lug ( 14 ) and the second contact lug ( 20 ; 20 a , 20 b ) are bent away through approximately 90.degree. in the direction toward the printed circuit board ( 5 ).

7. The contact system as claimed in claim 5 , wherein the first contact lug ( 14 ) is bent away through approximately 90.degree. opposite to the printed circuit board ( 5 ) and opposite to the second contact lug (( 20 ; 20 a , 20 b ).
