ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a plug connector.
Such a plug connector, known from DE 297 04 161 U1, is linearly embodied and is provided on its connecting end with the printed circuit board with a collar surrounding it acting as a travel limitation element. This known plug connector is connected with the printed circuit board in the direction of its longitudinal extension and of the longitudinal extension of the contact element, and therefore perpendicularly in respect to the plane of the printed circuit board, This way of connecting a plug connector with a printed circuit board requires a great amount of space above the plane of the printed circuit board, not only for the connection per se, but also for the plug-in process. This apace, or respectively room, is not available, or respectively provided in many cases.
SUMMARY OF THE INVENTION
It is the object of the present invention to create a plug connector of the type mentioned at the outset which, for the pluggable connection with the printed circuit board, requires less space above the printed circuit board, but nevertheless results in a dependable connection with the printed circuit board.
It is achieved by means of the steps of the invention that the insertion movement of the plug connector toward the printed circuit board required for connecting can take place in a direction parallel with and slightly above the surface of the printed circuit board, so that the plug connector extends less far above the surface of the printed circuit board. The travel limitation element provided on the housing or the printed circuit board leads to a dependable connection and short distances between the housing of the plug connector and the printed circuit board.
It is achieved by means of the characteristics that plugging the plug connector, or respectively its contact elements, into the bores of the printed circuit board can take place without a tilt moment, which possibly could affect the plug connector disadvantageously.
In a preferred development of the present invention, an angle plate is provided on the housing, which rests on the appropriate surface of the printed circuit board and in this way assures an exact and dependable contact, and which can also absorb forces acting on the plug connector during the insertion of the plug.
A further improvement and simplification of the mounting, or respectively pluggable connection of the plug connector on a printed circuit board, along with the simultaneous simplest possible design of an appropriate mounting tool, is achieved.
The contact element can be of one piece, which is possible up to a defined minimal distance between the plug connector and the printed circuit board, since in this case the contact element can be designed to be appropriately angled by simply bending it.
If this said distance between the plug connector and the surface of the printed circuit board falls below a minimum, it is practical to design the contact element in several pieces. Even lower structural heights can be achieved by means of this than is possible with bending the contact elements. This is of particular importance in connection with the increasingly greater packing densities in electronic components. Moreover, this makes it possible to realize different structural heights, since the connecting element on the plug side remains the same and only the structural height, or respectively structural length, of the connecting ends on the printed circuit side is changed. A further advantage lies in realizing different surfaces of the connecting ends, so that they can be matched to the respective functions and requirements. This also applies to a correspondingly optimum selection of the materials on the respective connecting ends. Finally, a variety of combinations is possible, depending on the required design of the shapes of the connecting ends. The engagement area in accordance with the characteristics of claim

can be realized in a variety of ways, for example by a transverse bore with or without a pin, by an circular groove with or without a ring, by a cone-shaped collar at the circumference, by surfaces parallel with the surface of the printed circuit board, or the like.
Further details of the invention can be taken from the following description, in which the invention will be described and explained in greater detail by means of the exemplary embodiments represented in the drawings.
