Background
A conductor circuit unit which is designed to be flexible for use in the automotive field is known from the prior art, which is also known in the english sector as Flexible Printed Circuit (flexible printed circuit) or abbreviated FPC, and which is able to design and ensure electrically conductive connections between different components of the electrical system of the motor vehicle.
In order to ensure such a conductively designed connection, a suitable joining technique or a suitable composite structure is required between the flexibly designed conductor circuit unit and the coupled component.
The prior art for this is, for example, publications DE 202013104464 (U1), CN213636352 (U) or US 6066000 (A).
Disclosure of Invention

In particular, it is possible here for the flexibly designed conductor circuit unit to be mechanically positioned and fastened at the printed circuit board before the electrically conductive connection is designed, so that a reliable material-fit connection can then be designed between the flexibly designed conductor circuit unit and the printed circuit board, which material-fit connection is designed reliably over the entire life of the connection device.
For this purpose, according to the invention, a connection device is provided between the printed circuit board and the flexibly designed conductor circuit unit. The first electrical connection region of the flexibly designed conductor circuit unit and the second electrical connection region of the printed circuit board are connected to one another in a material-to-material and electrically conductive manner. In particular, such a connection is constructed in a welded manner, and preferably in a laser-welded or ultrasonic-welded manner.
Furthermore, a receiving element of the second mechanical connection region of the printed circuit board is arranged on the surface of the printed circuit board. In particular, such a connection is constructed in a welded manner, and preferably in a laser-welded or ultrasonic-welded manner.
The first mechanical connection region of the flexibly designed conductor circuit unit is at least positively received in the receiving element of the second mechanical connection region of the printed circuit board.
Advantageous refinements and improvements of the device specified in the independent claims can be achieved by the measures recited in the dependent claims.
It is to be noted here that the printed circuit board (Printed Circuit Board in the english language or abbreviated to PCB) is also or is known as a carrier element of an electronic component in principle, which is used in particular for the mechanical fastening and the electrical connection of the electronic components to one another. For this purpose, the printed circuit board comprises an electrically insulating material, in or in which an electrically conductive connection, preferably made of copper, a so-called conductor circuit, is furthermore arranged. In particular, the electronic component is connected to the printed circuit board in a material-fitting manner, such as, in particular, by soldering, so that an electrically conductive connection to the conductor circuit is also formed.
Suitably, the flexibly configured conductor circuit unit comprises at least one conductor circuit configured from an electrically conductive material. The conductor circuit is accommodated in or at the flexibly designed carrier material. Preferably, the carrier material can be configured as a film constructed from a polymeric material. Such a flexibly designed conductor circuit unit offers the advantage that a relatively less complex and cost-effective connection can be produced with great reliability by means of the conductor circuit. It is therefore possible to provide a conductive connection which is configured as intended without interrupting the signal or power transmission.
Advantageously, the receiving element of the second mechanical connection region of the printed circuit board is configured as an insert. This offers the particular advantage that a reliable and yet relatively easy to design and cost-effective solution can be provided. In particular, the first mechanical connection region of the flexibly designed conductor circuit unit can be inserted into the receiving element.
In particular, the receiving element and the preferred insert can be configured as a so-called SMD component element. The SMD component parts are surface mount components (Surface Mounted Device in the english language or abbreviated to SMD) which are connected to the printed circuit board directly by means of soldering, for example.
Advantageously, receiving elements are arranged on both sides of the second electrical connection region of the printed circuit board. In this way, a stable design can be provided in which the first mechanical connection region of the flexibly designed conductor circuit unit is received in the receiving element of the second electrical connection region of the printed circuit board.
Furthermore, it is also advantageous if the first mechanical connection region of the flexibly designed conductor circuit unit comprises a guide rail. This offers the particular advantage that a reliable and yet relatively easy to construct and cost-effective solution can be provided. In particular, the first mechanical connection region of the flexibly designed conductor circuit unit can be inserted into the receiving element.
The solution according to the invention generally offers the advantage that complex and costly solutions for the material-matched, mechanical positioning or fastening of the flexibly designed conductor-circuit units on the printed circuit board can be dispensed with. Furthermore, additional fastening or positioning elements can be dispensed with in particular.
The invention also relates to a battery module comprising a connection device according to the invention.
The invention also relates to a method for producing a connection device between a printed circuit board and a flexibly produced conductor circuit unit. The first electrical connection region of the flexibly designed conductor circuit unit and the second electrical connection region of the printed circuit board are connected to one another in a material-to-material and electrically conductive manner. In particular, such a connection is constructed in a welded manner, and preferably in a laser-welded or ultrasonic-welded manner.
Furthermore, a receiving element of the second mechanical connection region of the printed circuit board is arranged on the surface of the printed circuit board. In particular, such a connection is constructed in a welded manner, and preferably in a laser-welded or ultrasonic-welded manner.
The first mechanical connection region of the flexibly designed conductor circuit unit is arranged at least in a form-fitting manner in the receiving element of the second mechanical connection region of the printed circuit board. In particular, the connection between the first mechanical connection region and the second mechanical connection region can be made temporally before the material-matched connection of the first mechanical connection region and the second mechanical connection region.
It is also noted here that the first electrical connection region and the first mechanical connection region are preferably configured spatially separate from one another, and the second electrical connection region and the second mechanical connection region are preferably configured spatially separate from one another.
