Description

[0001] manual:

[0002] The present invention relates to a plug connector for direct electrical contact with a circuit board, the plug connector having: at least one circuit board contact portion to be shielded; a shielding body, which is used to shield the at least one circuit board contact portion; and a contact portion carrier, which is accommodated in the shielding body and has at least one circuit board contact portion to be shielded.

[0003] PCB plug connectors are used to conduct current within a PCB or between multiple PCBs. It is necessary to first ensure that the PCB contacts are adequately shielded, which can improve electromagnetic compatibility and ensure that signal transmission and signal processing are not disturbed.

[0004] In order to establish a permanent connection between the plug connector and the circuit board, a variety of solutions are known in the prior art in which the plug connector is fixed on the circuit board by means of a crimping technique. Here, the crimping pin is pressed into the hole of the circuit board.

[0005] The disadvantage of crimping technology is that crimping devices are installed on the plug connector, which ensure the simple installation of the plug connector on the circuit board. At the same time, the circuit board contact must be fully shielded, which makes the manufacture of the plug connector very complicated.

[0006] The object of the present invention is therefore to provide a plug connector for direct electrical contact with a circuit board, which ensures shielding of the circuit board contacts, improves mounting on the circuit board and optimizes the production of the plug connector.

[0007] This object is achieved by the combination of features according to claim 1 .

[0008] According to the present invention, a plug connector for direct electrical contact with a circuit board is proposed, the plug connector having: at least one circuit board contact to be shielded; a shielding body, which is used to shield the at least one circuit board contact; and a contact carrier, which is accommodated in the shielding body and has at least one circuit board contact to be shielded. Here, at least two crimping elements are arranged on the connecting surface of the shielding body facing the circuit board for crimping into the circuit board. In addition, the mounting opening for mounting the contact carrier in the shielding body is closed by means of a shielding plate, and at least one circuit board contact and the crimping element have a common, in particular the same, insertion direction. The advantage of this is that at least one circuit board contact in the contact carrier is optimally shielded by means of the shielding body, and at the same time can be introduced into the interior of the shielding body by means of the mounting opening, and can be fixed by means of the shielding plate, which can also additionally shield the circuit board contact.

[0009] In a preferred embodiment, a mounting notch is formed on the connection surface, the mounting notch extending at least partially along the connection surface and the installation opening starting from the first axial end of the installation opening. In this way, the contact carrier and the circuit board contact are pushed in from one side of the installation opening, and the mounting notch prevents the circuit board contact from hitting the shield and thereby bending.

[0010] The plug connector is preferably designed so that at least one circuit board contact portion is formed to be bent, in particular substantially bent at a right angle or L-shaped. In this way, the circuit board contact portion may extend in a direction deviating from the plug connector insertion direction, thereby improving the installation or connection of the conductor at the circuit board contact portion.

[0011] In an embodiment of the present invention, it is provided that the contact carrier is fixed on the shielding body, in particular, on the axial end of the mounting slot, by means of a shielding plate in a form-fitting manner. This has the advantage that the shielding plate can fix the contact carrier on the one hand, and shield the contact carrier in the direction of the mounting opening on the other hand, thereby achieving complete shielding except in the direction of the connection surface.

[0012] In addition, a feasible design scheme is to design at least one circuit board contact as a crimping contact. This has the advantage that when the plug connector is fixed on the circuit board by means of the crimping element, contact with the circuit board can be established by means of the crimping contact at the same time.

[0013] In a further advantageous variant, it is provided according to the invention that the first end and the second end of the at least one circuit board contact protrude from the contact carrier. In an embodiment variant, the plug connector according to the invention is designed so that the contact carrier is accommodated in the mounting opening so that the first end of the at least one circuit board contact protrudes from the connection surface. It is particularly advantageous if the shield has a receiving socket with a receiving space for accommodating a corresponding mating plug, and the at least one circuit board contact is arranged with the second end in this receiving space. In this way, the contacting of the plug connector is optimized.

[0014] In a preferred embodiment of the present invention, the contact carrier is designed in two parts. In addition, there is a possible variant, in which at least one circuit board contact is accommodated in the contact carrier, so that a first section of the circuit board contact is completely accommodated in a first part of the contact carrier, and a second section of the circuit board contact is partially accommodated in the first part. The second part of the contact carrier is fixed to the axial end of the first part, so that the second section of the circuit board contact is completely surrounded by the first part and the second part. In addition, in one embodiment, the second part of the contact carrier is fixed to the first part of the contact carrier with a snap-in connection. This improves the installation of at least one circuit board contact in the contact carrier.

[0015] In another advantageous embodiment variant, it is provided that each crimping element is fixed, in particular welded, in a receiving cavity of the shield body corresponding to the crimping element. This has the advantage that the installation position of the crimping element on the shield body can be predetermined and the installation can be optimized.

[0016] Advantageously, the plug connector is designed such that the shielding plate is fixed in a plate recess of the shielding body, which is formed in particular in a recess-like manner in the mounting opening. The plate recess extends from the connection surface at least to the mounting opening. In this way, the shielding plate can be mounted from the side of the connection surface.

[0017] According to the present invention, a method for manufacturing a plug connector according to the above disclosure is also proposed, wherein firstly, a contact carrier and at least one circuit board contact are introduced into a mounting opening along a mounting notch of a shielding body. Subsequently, a shielding plate is introduced into a plate notch of the shielding body. Therein, at least two crimping elements crimped into a receiving cavity of the shielding body are appropriately mounted in the shielding body in a connection surface facing the circuit board, in particular by means of laser welding, and the crimping elements are oriented so that they have a common, in particular the same, insertion direction with at least one circuit board contact. This has the advantage that the manufacture of the plug connector can be optimized.

[0018] In an advantageous embodiment, it is provided that the contact carrier is pre-fixed in the shield body after introduction, in particular by means of a snap-in connection, so that during the production process it is possible to prevent the contact carrier from deviating from the installed position in the shield body.

[0019] The production method is preferably carried out in such a way that the shielding plate is fixed in the sheet metal recess after introduction, in particular by means of laser welding, thereby fixing the contact carrier in the shielding body.

[0020] Furthermore, a possible embodiment is that the shielding plate is produced by means of a stamping and strip coating process before being introduced into the board recess. It is further advantageous if at least one circuit board contact is produced by means of a stamping and strip coating process before being introduced into the contact carrier. In this way, automatic production of the shielding plate and the circuit board contact can be achieved. The strip coating process is in particular a strip plating process.

[0021] In another advantageous variant, before the contact carrier is introduced into the mounting opening, at least one circuit board contact is introduced into the first part of the contact carrier and the contact carrier is subsequently assembled by means of a snap-in connection between the first part and the second part. This improves the mounting of the circuit board contact in the contact carrier.

[0022] In an advantageous embodiment of the invention, the contact carrier, in particular the first part and the second part, are manufactured by means of injection molding before the at least one circuit board contact is introduced. Furthermore, in an advantageous embodiment according to the invention, it is provided that the crimping element is fixed to the shield body by means of laser welding. In an advantageous embodiment variant, it is provided that the crimping element is manufactured by means of a stamping and strip coating process before being inserted into the accommodating cavity of the shield body. The strip coating process is in particular a strip electroplating process. Furthermore, in one embodiment, it is advantageous that the shield body is manufactured by means of a die-casting process before the contact carrier is introduced. The corresponding manufacturing method of the individual components is particularly suitable for automatic manufacturing.

[0023] The above features can be combined arbitrarily as required as long as they are technically feasible and not contradictory.

In addition, the installation opening 21 for installing the contact carrier 5 in the shielding body 2 is closed by means of the shielding plate 6, and at least one circuit board contact 3 and the crimping element 4 have a common, in particular the same insertion direction S. A mounting notch 23 is formed on the connection surface 22, which extends partially along the connection surface 22 and the mounting opening 21 starting from the first axial end of the mounting opening 21.

Therein, the contact carrier 5 is accommodated in the mounting opening 5, so that the first end 31 of each circuit board contact 3 protrudes from the connection surface 22.

[0032] In addition, at the axial end of the mounting slot 23, the contact portion carrier 5 is fixed to the shielding body 2 by means of the shielding plate 6 in a form-fitting manner.

In addition, the first portion 51 and the second portion 52 abut the side surface of the mounting slot 23.

[0033] Each crimping element 4 is welded in a receiving cavity 24 of the shielding body 2 corresponding to the crimping element 4. In addition, the shielding plate 6 is fixed in a plate notch 26 of the shielding body 2, which is formed in the mounting opening 21 in a similar recessed form.
