The The invention relates to a printed circuit board connector according to The preamble of claim 1 and a method for connecting Printed circuit boards with the PCB connector.

A generic printed circuit board connector is from the DE 296 14 725 U1 known. This has a press-in pin made of conductive material and an electrical insulating body. The press-in pin has at its two ends a press-in zone, whereby a frictional and thus solderless connection with the circuit boards is made possible. Due to the height and length of the body of the insulator of the printed circuit board connector, the PCB spacing is determined. A disadvantage of such printed circuit board connectors is that they are very complicated to produce and suitable only for one type of connector - single row, double row, straight or angled - and a predetermined PCB spacing.

Of the Invention is the object of a low effort producible and adaptable to different requirements PCB connectors, as well as a simple method of connection to create printed circuit boards.

These Task is through a printed circuit board connector with the features of claim 1 and a method having the features of claims 15, 16 or 17 solved.

According to the invention a printed circuit board connector on an insulating body, in a variety of press-fit pins are used, the two sides protrude with contact terminals from the insulator. The insulator is in this case with a widened base executed so that the socket shoulder an attack surface forms for a holding tool. This solution has the advantage that a holding tool over the insulating body The base can be fixed in position and thus simply the press-fit pins can be used, creating a cost-effective Production is possible. Another advantage is that the holding tool through the base of the insulator with the Also fix the press-in pins during assembly with printed circuit boards can, whereby the assembly is very simplified.

The Height and base shoulder width of the base is preferably essentially the same regardless of a connector type. This allows the same holding tool with different connector types be used.

At End faces of the base are advantageously Referenzierflächen for positional positioning of the insulating body during assembly formed with the press-fit pins. This will be an exact and safe placement of the insulator with Press-in pins allows.

The Referencing surfaces of the equipped with press-fit pins Sockets are preferably for positional positioning during assembly formed on at least one printed circuit board, whereby a fast, accurate and easy installation is possible.

The Referencing surfaces are, for example, grooves that are very can be manufactured inexpensively.

The Injection pins can each have a T-shaped Be carried out extension extension. This one will be in one corresponding recording of a pin channel of the insulator immersed and lies with a stop shoulder on a support shoulder the recording, whereby the immersion depth of the press-in pins advantageously is limited.

At the Press-in pin may be formed, for example, a knob the press-in pin in a Pinkanal frictionally is held. This allows the press-fit pin after insertion in the insulating body, for example when transporting can not fall out of this.

The Contact terminals of the press-fit pin are preferred Solder or press-fit, the inexpensive to produce and can be easily connected to the circuit boards.

Of the PCB connector can be single or multi-row be, and thus to different requirements in the connection be adapted from printed circuit boards.

In For example, a variety of the insulating body of injection pins next to each other and in at least one row arranged to be used.

at the Monday of the circuit boards is advantageously either a internal distance from inner surfaces of two printed circuit boards the geometry of the PCB connector, or an outer one Distance from outer surfaces of two printed circuit boards adjustable by a press tool. This has the advantage that the PCB connector with the circuit boards in a simple manner to different requirements, for example in relation to the Manufacturing tolerances of the printed circuit boards and the printed circuit board connector, can be adjusted.

In an advantageous embodiment, a portion of a press-fit pin located outside the insulator is angled approximately at right angles. This makes it possible that printed circuit boards can be connected to each other, the senk are arranged right or right angles to each other.

The PCB connectors can be used to simplify PCB assembly with the transverse sides can be arranged next to each other.

at an inexpensive method for mounting the PCB connector with the circuit boards, the PCB connector is using a holding tool fixed. After that, the two circuit boards are going through Press-in tools on the press-fit pins of the PCB connector put on and pushed onto the contact connections, until stop surfaces the pressing tools abut each other. Thus, the distance becomes the circuit boards to each other determined by the stop surfaces.

In order to the distance between the circuit boards to each other over the insulator the PCB connector can be determined is another inexpensive assembly method applicable. Here we the first printed circuit board fixed by a first counter-holder and the Printed circuit board connector is with the press-fit pins in recesses the first circuit board with a first press tool over pressed the pressure shoulder of the press-fit pins. Subsequently, will the second circuit board is fixed in position by a second counter holder and the press-fit pins of the circuit board connector with a second Press-in tool which acts on the first circuit board in recesses pressed the second circuit board.
