It is preferable to make the printed circuit board into a flexible printed circuit board.

In particular, the printed circuit board can have a plurality of plug connectors that are soldered to the printed circuit board in a planar manner. Preferably, the plug connectors are contactable via a plurality of electrically conductive lines of the printed circuit board.

Another advantageous way is that the plug connector has a plurality of contacts that are not electrically connected to each other, and one of the contacts is contacted via at least one electrically conductive line of the printed circuit board.

In particular, at least one of the contacts can be electrically inactive, for example at least one of the contacts is used as an auxiliary guide or codec.

According to a further development, the printed circuit board has at least two lines connected to at least one plug connector.

Further, the plug connector can be a flat socket.

According to one embodiment, the plug connector has a brake or a brake release. For example, a flat socket can be made using the FASTON principle.

Another advantageous embodiment is to solder the plug connector to the printed circuit board by reflow soldering.

According to another modification, the plug connector has a stop structure that ensures that the position of the plug connector does not move on the printed circuit board.

The purpose of using such a stop structure is to fix the position of the plug connector prior to soldering to prevent the plug connector from slipping during the soldering process (the process of reflow soldering).

According to another modification, the stop structure has a groove, a projection, or a notch.

An advantageous embodiment is that the plug connector is a surface mount plug connector or has a surface mountable construction.

According to one configuration, the plug connector is a high current plug connector. In particular, the plug connector can be applied to currents above 2.5A.

According to another configuration, the printed circuit board is soldered to the second printed circuit board. The second printed circuit board is preferably a rigid circuit board (non-flexible circuit board). The second printed circuit board can also be a circuit board having a plurality of layers, wherein the printed circuit board is soldered to the intermediate layer of the second printed circuit board.

Another possible way is to connect the second printed circuit board to a piece of flexible printed circuit board, for example, the flexible printed circuit board protrudes beyond the second printed circuit board.

Another construction solution is to use a single connector to bring together multiple plug connectors. For example, the connector can be a plastic connector.

Another improvement is to place a plug connector on both the front and back sides of the printed circuit board.

It is preferable to have conductive lines on both the front and back sides of the board, especially to set up pairs of conductive lines, because this can achieve lower inductance.

Moreover, the present invention also includes a plug connector having at least one plane for soldering on a printed circuit board.

In a further development, the plug connector has at least one latching structure by means of which the plug connector can be attached to the printed circuit board. The plug connector preferably has a surface mountable construction.

Furthermore, the invention also includes a method of manufacturing a plug-in device having the steps of: placing at least one plug connector on a printed circuit board; - printing the at least one plug connector with printing The boards are soldered together.

According to a further development, the at least one plug connector is a surface mount plug connector.

According to another refinement, the at least one plug connector is soldered to the printed circuit board in a reflow manner.

According to another refinement, the at least one plug connector is secured to the printed circuit board by a stop structure.

According to one configuration, the printed circuit board is a flexible printed circuit board, especially a flexible printed circuit board.

The embodiments of the present invention will be described below in conjunction with the drawings.

Figure 1 shows a front view of a plug connector (101) soldered to a printed circuit board (102). The curved regions (105, 106) are used to form a contact with a mating member (not shown in Fig. 1) with which the shape is mated. A plane (103) of the plug connector (101) is soldered to the printed circuit board (102), and a cross section of the plane (103) is shown in a front view of Fig. 1.

The printed circuit board (102) has at least one electrically conductive line connected to the flat solder portion (103). In addition, the printed circuit board (102) is preferably a flexible printed circuit board, especially a flexible printed circuit board, such that the plug connector (101) can be connected to the mating component via the printed circuit board (102) ( For example, a plug piece) is connected.

The plug connector (101) is preferably a surface mount plug connector.

Figure 2 shows a perspective perspective view of the plug connector (101) and the printed circuit board (102). According to this embodiment, a plurality of adjacently arranged plug connectors can be provided. The flexible printed circuit board (102) extends in the direction (107) so that a cable-like connection can be formed via a combination of the plug connector (101) and the printed circuit board (102).

This solution is particularly suitable as a plug-in device, for example such a plug-in device can be inserted into an existing plug piece (for example a 6.3 mm plug-in piece). The plug connector (101) can be connected to the plug piece or inserted into the plug piece. In particular, the plug tabs can be inserted in a vertical or horizontal manner with a center distance of 10 mm for the adjacent plug tabs.

For example, the plug connector (101) is a flat socket having a surface mountable construction. The plug connector (101) is soldered directly onto the printed circuit board (102) in a planar manner, such as a printed circuit board (102) being a single circuit board or a flexible printed circuit board. It is preferable to carry out the welding by the reflow method.

Figure 3 shows the bottom of the plug connector (101). The bottom of the plug connector (101) has a stop structure (104), such as a stop structure that is formed as a small projection, groove, or notch. The action of the stop structure (104) secures the plug connector (101) to the printed circuit board (102) to prevent positional movement of the plug connector (101) due to flux melting and expansion of the plug connector (101). .

Another possible way is to make the plug connector (101) using the so-called FASTON principle to reduce the force acting on the flat welded portion (103) when the plug connector (101) is inserted and released.

It is also possible to solder the plug connector (101) to a general printed circuit board (102) (PCB: Printed Circuit Board). In addition, multiple plugs can also be inserted The connectors are arranged together. In particular, a plurality of plug connectors or flat sockets can be brought together by a plastic connector to simplify the operation of setting and/or positioning the plug connector or the flat socket.

The plug device and the plug connector formed by the plug connector and the printed circuit board of the present invention are all suitable for high current connection, especially for currents above 2.5A.
