Detailed Description
Fig. 1 shows an embodiment for a contact system 1. The contact system 1 comprises a printed circuit board 2. The printed circuit board 2 has in this embodiment four perforations 3, 4, 5 and 6 which are jointly spaced apart from one another in a row. The perforations 3, 4, 5 and 6 are each configured to receive a press-in contact. For this purpose, the perforations each have a metal layer formed on the perforated wall of the perforation or a metal cylinder. The metal layer 7 at the perforated wall of the perforation 3 is exemplarily marked.
The printed circuit board 2 also has conductor tracks 8, which are connected to the metal layer 7 in an electrically conductive manner. The press-in contacts introduced into the through-holes 3 can then be electrically connected to further electronic components connected to the printed circuit board 2.
In this embodiment, the printed circuit board 2 also has two perforations 9 and 10. The perforations 9 and 10 are each configured to receive an anchor element. The printed circuit board 2 has a conductive layer 11 in the region of the through-holes 9 and a conductive layer 13 in the region of the through-holes 10. The electrically conductive layers 11 and 13, in particular the conductor tracks, each form the Surface of the printed circuit board and are each designed for a Surface-soldering connection, in particular an SMD-soldering connection, with the solder feet (smd=surface Mounted component).
The contact system 1 also has an engagement aid 14. The joining aid is in this embodiment constructed as a plastic element.
In the present exemplary embodiment, the joining aid 14 has a plastic body in which a funnel-shaped recess for introducing the press-in contact is formed.
Fig. 1 shows for this purpose a molding module 30, in particular an inverter, by way of example. In the present exemplary embodiment, four press-in contacts 31, 32, 33 and 34, which each protrude in the same direction, are formed at the molding module 30 from the molding module 30. The press-in contacts 31, 32, 33 and 34 each have a press-in section for pressing into the printed circuit board 2 and pressing there into a perforation, for example perforation 3, 4, 5 or 6. In this embodiment, the press-in contacts form a control joint for the molding module 30.
In the present exemplary embodiment, the engagement aid 14 has a catch funnel 24 for the press-in contact 31, a catch funnel 25 for the press-in contact 32, a catch funnel 26 for the press-in contact 33 and a catch funnel 27 for the press-in contact 34. The press-in funnels 24, 25, 26 and 27 each open into a guide shaft, which in the present exemplary embodiment is embodied in the form of a column. The guide rod 23 connected to the catch funnel 24 is shown by way of example. The catch funnel 24 forms, together with the guide rod 23, a through-hole of particularly thin design in the joining aid 14, in particular in the plastic body of the joining aid 14.
In this embodiment, the cone angle 28 of the introduction funnel 24 is 48 degrees.
The joining assistance element 14 is designed for soldering, in particular SMD soldering (smd=surface mounted component), to the printed circuit board 2. For this purpose, the joining aid 14 has two solder feet 19 and 20, which are each inserted into one of the fixing journals 17 and 18 of the joining aid 14. The fixing journals 17 and 18 are molded respectively to the plastic body of the auxiliary joining element 14.
In the present exemplary embodiment, the solder feet 19 and 20 are embodied as plate corners, in particular as punched meshes or as leadframes. The solder feet 19 and 20 each have a perforation at the fastening leg for the insertion or reception of the fastening element 17 or 18. The solder feet 19 and 20 each have a solder leg 22 or 21. In the present exemplary embodiment, the soldering leg 22 of the soldering leg 19 is soldered to the metal layer 11 by means of the flux 12. In the present exemplary embodiment, the soldering leg 21 of the soldering foot 20 is connected to the metal layer 13 by soldering with the aid of the flux 12. In this embodiment, a recess for the insertion of the anchoring element, which is shown in particular in fig. 2, is formed in the soldering leg.
In this embodiment, the molding module 30 also has additional electrical connectors. In the present exemplary embodiment, the molding module 30 is embodied as a semiconductor-half bridge. The ground connection 43, the supply connection 44 and the output connection 42 are each formed as a punched mesh and protrude together, in particular extending in the same direction, out of the molding module 30.
Now, the principle of the operation of the contact system 1 and the engagement method for engaging the press-in contact will be explained below.
The auxiliary joining element 14 can be connected to the printed circuit board 2 in a plug-in manner using anchor elements 15 and 16, which are in this exemplary embodiment each configured as journals. For this purpose, the anchoring elements 15 or 16 are inserted into the corresponding through-holes 9 or 10 in the printed circuit board 2. The printed circuit board 2 is previously printed with solder paste 12. The soldering leg 22 is placed on the metal layer 11 after the joining assistance member 14 is joined to the printed circuit board 2, and the soldering leg 21 is then placed on the metal layer 13.
The printed circuit board 2 can then be soldered in a reflow soldering oven, in particular together with other electronic components not shown in fig. 1. The flux 12 extending between the printed circuit board 2, in particular the metal layer 11 or 13, and the solder feet 19 and 20, in particular the solder legs 22 and 21, can then melt and connect the solder legs 21 and 22 to the printed circuit board 2 in a material-locking manner. The perforations formed by the catch hoppers 24, 25, 26 and 27 then pass precisely into the corresponding perforations 3,4,5 and 6 in the printed circuit board 2.
The molding module 30 can then be pressed into the printed circuit board 2. The molding module 30 is, for example, already screwed or plug-connected to a further component of the inverter or the electric motor. The printed circuit board 2 can then be inserted onto the molding module 30, as outlined by arrows 36 and 37. The press-in contacts 31, 32, 33 and 34 can then be snapped and guided into the respective guide shaft by means of the respective snap-in funnel 24, 25, 26 and 27, respectively assigned to the press-in contact, with the corresponding tolerances to the snap-in funnel. The press-in sections 35 of the press-in contacts can then be pressed into corresponding bores in the printed circuit board 2 during the pressing of the printed circuit board 2 further onto the molding module 30. The press-in contact 31 is then pressed into the through-hole 3 of the printed circuit board 2, the press-in contact 32 into the through-hole 4 of the printed circuit board, the press-in contact 33 into the through-hole 5 of the printed circuit board and the press-in contact 34 into the through-hole 6 of the printed circuit board, and the printed circuit board 2 is electrically contacted there in each case.
Fig. 2 shows the joining assistance member 14 already shown in fig. 1 in a top view. The catch hoppers 24, 25, 26 and 27 are each arranged in a row along the longitudinal extension 40 of the auxiliary engagement element 14. The braze feet 19, which are inserted onto the fixed journals 17, have a void 38 at the braze leg 22. The braze feet 20, which are inserted onto the fixed journal 18, have voids 39 at the braze legs 21. In the present exemplary embodiment, the recesses 38 and 39 are each U-shaped. The soldering legs 21 and 22 can then enclose the anchoring element 15 or 16 shown in fig. 1 when being inserted onto the plastic body 41 of the joining aid 14.
In the present embodiment, the anchoring element 15 extends orthogonally to the fixing element 17. In this embodiment, the anchoring element 16 extends orthogonally to the fixing element 18.
