Description

Technical field

[0001] The present invention relates to a printed circuit board (PCB) contact socket for contacting contact elements such as cable lugs with a printed circuit board. The invention further relates to a multi-circuit board contact socket for contacting a plurality of contact elements, in particular cable lugs, with a printed circuit board. State of the art

[0002] For power distribution systems in the automotive sector, printed circuit boards (PCBs) are required, onto which electronic components are mounted. The incoming and outgoing power conductors are connected to the PCB using terminals, such as cable lugs. This mounting of cable lugs on the PCB takes up a significant amount of space, which is then unavailable for other electronic components. Due to the design of the power distribution system, it may also be necessary for conductors to cross or overlap on the PCB. All of this necessitates the use of larger PCBs, thus requiring more installation space in the vehicle.

[0003] US Patent 10,069,223 B2 discloses an electrical cable connector that can be configured for mounting on a printed circuit board. The electrical connector comprises a connector housing and a pair of electrical terminals configured for mounting on electrical cables. The electrical terminals can be identical in one example.

In particular, the device comprises an insulating housing with a stamped and formed power distribution frame and a removable cover. The frame includes a plurality of dependent pins and a central section to which a power cable can be attached. The multiple pins, arranged on opposite sides of the central section, extend downwards through the housing to make a connection with multiple conductor tracks on the circuit board. The cover snaps onto the top of the housing to conceal the power cable attachment point.

[0005] US 2016 / 0 240 948 A1 discloses a power connector. The power connector has a printed circuit board, a conductive wire, an insulating base, and at least one conductive terminal. The at least one conductive terminal has a first terminal section that is electrically connected to the printed circuit board and a second terminal section that is electrically connected to the conductive wire. The at least one conductive terminal is fixed in the insulating base such that an upper end of the first terminal section protrudes from a lower face of the insulating base to establish an electrical connection with the printed circuit board.

[0006] CN 110 073 552 A discloses an electrical connector with an insulating body and at least one electrically conductive terminal, wherein the insulating body has at least one terminal slot, the electrically conductive terminal is assembled and attached to the terminal slot, the electrically conductive terminal has a pair of first connection sections coupled to an external circuit board, a second connection section coupled to a cable, and an intermediate connection section connecting the first connection sections to the second connection sections, wherein the first connection sections, which extend in the same direction as the conductive terminals, are attached to the circuit board, and the intermediate connection section extends perpendicular to the direction of attachment.

[0007] DE 20 2009 018 730 U1 discloses a connection arrangement on printed circuit boards. Description of the invention

[0008] One objective of the invention is therefore to create a concept for contacting electrical conductors with contact parts such as cable lugs on a printed circuit board that does without the disadvantages described above with regard to installation space in the vehicle.

[0009] In particular, an object of the invention is to create a stable and space-efficient contacting of contact parts, especially cable lugs, on a printed circuit board.

[0010] The problem is solved by the subject matter of the independent claims. Advantageous embodiments of the invention are specified in the dependent claims, the description, and the accompanying figures.

[0011] The inventive solution is based on the idea of ​​creating a contact socket (also called a PCB contact socket) for contact parts such as cable lugs, which allows the contact parts to be positioned and connected above the circuit board. The space on the circuit board below the contact socket is then freed up to place additional electronic components on the board or to reduce the size of the circuit board and thus save installation space in the vehicle.

[0012] The contact base allows contact elements, such as cable lugs, to be mounted at different heights above the circuit board and connected to it. This enables the integration of varying heights, for example, to accommodate intersecting or overlapping conductors on the circuit board. The contact base facilitates space-efficient designs for power distribution units.

[0013] The contact socket makes contact with the printed circuit board (PCB) and, for example, with a threaded stud, with a contact element such as a cable lug and attached wire or cable. The entire contact area from the PCB to the contact surface of the contact element or cable lug is made of an electrically conductive material, such as copper. The entire assembly is then enclosed in a plastic housing, for example, overmolded or inserted into the housing. The contact socket can make contact with a single contact element, such as a cable lug, or it can be designed to accommodate multiple connections. Several such contact sockets can form a multi-contact socket, with the individual sockets being mechanically connected to each other, for example, by snap-fit ​​connections, screws, or welds.The screw and tensile forces of the conductor are transferred into the socket, so that no force is exerted on the circuit board. In addition to the cable lugs presented here, the contact elements can also include other types of contacts, such as crimp contacts, metal rings, metal forks, metal sleeves, metal clamps, plugs, sockets, etc. The contact elements generally serve to establish an electrical contact, for example, with a cable, wire, busbar, or electrical conductor.

[0014] The solution presented here can be used generally for electronic assemblies, for example for power distributors, in particular electronic power distributors and / or circuit board-based power distributors.

[0015] The solution presented here offers the advantage that the direction of exit and the number of lines can be determined modularly in all positions and locations thanks to the contact base.

[0016] Further advantages include the ability to use the same contact socket consistently, fully leveraging the principle of standardized parts. The contact socket can be used for various contact partners and contact component types, such as cable lugs. This results in lower logistics costs, as multiple contact sockets are no longer needed. The contact socket is compatible with all OEMs (Original Equipment Manufacturers).

[0017] According to a first aspect, the problem described above is solved by a printed circuit board contact socket for contacting contact parts, in particular cable lugs, with a printed circuit board, wherein the printed circuit board contact socket comprises the following: a plug-in socket for insertion into a printed circuit board; wherein the plug-in socket comprises a contact surface which, when the plug-in socket is inserted, is spaced away from the printed circuit board; a busbar which is housed in the plug-in socket, wherein the busbar comprises electrical contacts at a first end for establishing an electrical connection with the printed circuit board and at a second end comprises a support plate which rests on the support surface of the plug-in socket; and a current-carrying contact element which projects from the support plate of the busbar in a metallurgically bonded manner and is designed to establish a mechanical and electrical contact with a contact part, in particular a cable lug.

[0018] Such a PCB contact socket offers a stable and space-efficient way to connect components, especially cable lugs, to a printed circuit board (PCB). The PCB contact socket allows the components, particularly cable lugs, to be routed and connected above the PCB, leaving the space below the socket and the cable free for additional electronic components or for reducing the size of the PCB, thus saving space in the vehicle. The tightening and tightening forces of the cable are transferred into the socket, preventing any stress on the PCB. This protects the PCB from unnecessary stress.

[0019] According to an exemplary embodiment of the printed circuit board contact socket, the plug socket is made of plastic and the busbar is enclosed by the plug socket in an area between the first end and the second end of the busbar.

[0020] This offers the advantage that the plug-in socket is electrically insulating, thus providing protection against high voltages occurring on the busbar.

[0021] According to an exemplary embodiment of the printed circuit board contact base, the support plate of the busbar is enclosed laterally by the plug-in base, overmolded or inserted into the plug-in base.

[0022] This ensures that the busbar mounting plate is robustly attached to the plug-in base, and that attaching the contact part, especially the cable lug, to the mounting plate does not cause the mounting plate to slip on the mounting surface of the plug-in base.

[0023] According to an exemplary embodiment of the printed circuit board contact socket, the busbar is bent so that, when the socket is plugged in, the first end of the busbar and the second end of the busbar are arranged at a predetermined angle to each other.

[0024] The curved design has the advantage that the electrical contacts of the busbar can be inserted into the circuit board from above without much effort, and that the mounting plate is arranged, for example, parallel to the mounting surface of the plug socket, so that it can rest stably on the mounting surface, or that it can be arranged at any angle, which offers the advantage of flexibility in cable routing.

[0025] According to an exemplary embodiment of the printed circuit board contact socket, the plug socket comprises a plurality of plug pillars designed for plugging the plug socket into the printed circuit board in order to detachably attach the plug socket to the printed circuit board.

[0026] The plug socket can be conveniently inserted into designated holes in the circuit board via the plug-in pillars, creating a robust mechanical connection that can be released again by applying appropriate force.

[0027] According to an exemplary embodiment of the printed circuit board contact base, the current-carrying contact element is a contact bolt that protrudes from the mounting plate of the busbar.

[0028] A contact bolt like this makes it easy to attach the contact part, especially the cable lug. The contact part, particularly the cable lug, with an opening provided in the contact part or cable lug, can thus be easily guided over the contact bolt and attached.

[0029] According to an exemplary embodiment of the printed circuit board contact base, the current-carrying contact bolt is a threaded bolt designed to mechanically and electrically connect the contact part, in particular the cable lug, to the mounting plate of the busbar via a screw connection.

[0030] The threaded bolt allows the contact part, especially the cable lug, to be screwed onto the busbar, creating a stable mechanical and electrical connection.

[0031] According to an exemplary embodiment of the printed circuit board contact base, the current-carrying contact element is a contact tab that protrudes laterally from the mounting plate of the busbar.

[0032] This allows for an alternative fastening of the contact part or cable lug, which is easy to plug in and unplug.

[0033] According to an exemplary embodiment of the printed circuit board contact base, the contact part, in particular the cable lug, can be attached to the mounting plate of the busbar in different exit directions.

[0034] This allows the contact part, especially the cable lug, to be flexibly attached to the circuit board contact socket and thus to the circuit board. Depending on the installation space requirements in the vehicle, the exit direction of the contact part, especially the cable lug, can therefore be determined.

[0035] According to an exemplary embodiment of the printed circuit board contact socket, the printed circuit board contact socket includes a heat sensor which is attached to the plug socket and is configured to detect a temperature of the busbar.

[0036] This allows the heat generated to be detected directly at the busbar, reducing the reaction time in the event of a short circuit and enabling a faster response to such an event.

[0037] According to a second aspect, the problem described above is solved by a multi-circuit board contact socket for contacting a plurality of contact parts, in particular cable lugs, with a circuit board, wherein the multi-circuit board contact socket comprises: a first circuit board contact socket according to the first aspect; and a second circuit board contact socket according to the first aspect, which is arranged next to the first circuit board contact socket, wherein the contact surfaces of the respective plug sockets of the two circuit board contact sockets run parallel to each other.

[0038] Such a multi-circuit board contact socket offers stable and space-efficient contacting for numerous contacts, especially cable lugs, on the circuit board. With this multi-circuit board contact socket, a multitude of contacts, particularly cable lugs, can be routed and connected above the circuit board, leaving the space below the socket free for additional electronic components or for reducing the size of the circuit board, thus saving installation space in the vehicle.

[0039] According to an exemplary embodiment of the multi-circuit board contact socket, the second circuit board contact socket and the first circuit board contact socket are arranged laterally, laterally offset, or diagonally to each other.

[0040] A wide variety of geometric arrangements can be implemented with such a multi-circuit board contact socket. This allows the installation space requirements in the vehicle to be taken into account in a suitable manner.

[0041] According to an exemplary embodiment of the multi-circuit board contact socket, the contact surfaces of the plug sockets of the two circuit board contact sockets are arranged at the same or different heights above the circuit board when plug sockets are inserted.

[0042] This allows for flexible routing of contact components, such as cable lugs. The multi-circuit board contact base enables flexible implementation of different height variations in cable routing.

[0043] According to an exemplary embodiment of the multi-circuit board contact socket, the two circuit board contact sockets are mechanically connected to each other, in particular by means of latches, screws, welds or other connection techniques.

[0044] This allows the individual circuit board contact sockets to be connected to each other in a modular fashion.

[0045] The multi-circuit board contact socket can include, in addition to the two circuit board contact sockets described above, further circuit board contact sockets that are connected to each other in the same way. Brief character description

[0050] Fig. Figure 1 shows a 3D representation of a printed circuit board contact socket 100 according to an embodiment in a first view.

[0051] The printed circuit board contact socket 100 is used to connect contact parts, for example cable lugs, to a printed circuit board 150, which is shown here in Fig. 1 is shown schematically.

[0052] The printed circuit board contact base 100 comprises a plug-in socket 101, a busbar 110 and a current-carrying contact piece 120.

[0053] The socket 101 is designed for insertion into a printed circuit board 150. The socket 101 includes a contact surface 102 which, when the socket 101 is inserted, is spaced away from the printed circuit board 150. Fig. 1 shows a distance 151 between the support surface 102 and the circuit board 150.

[0054] The busbar 110 is housed in the plug-in socket 101. The busbar 110 comprises electrical contacts 111 at one end 110a for establishing an electrical connection with the circuit board 150 and a support plate 112 at one end 110b, which rests on the support surface 102 of the plug-in socket 101.

[0055] The busbar 110 can, for example, be formed as a metal sheet, as in Fig. Figure 1 shows a conductor, or it can generally refer to an electrical conductor carrying current. The electrical contacts 111 of the busbar 110 can be plugged into the circuit board 150 or inserted in another way to establish an electrical connection with corresponding conductors on the circuit board 150. The electrical contacts 111 of the busbar 110 can, for example, be comb-shaped, as shown in Figure 1. Fig. 1 shown, or it may be a single pin that makes the electrical connection with the circuit board 150, or they may be shaped in other ways.

[0056] Preferably, the electrical contacts 111 of the busbar 110 are inserted into corresponding openings in the circuit board to establish a conductive connection, but other methods of establishing an electrical connection are also possible. For example, the electrical contacts 111 can be soldered to the circuit board, inserted into connectors on the circuit board 150, or otherwise electrically connected to the circuit board 150.

[0057] The electrical contacts 111 can, for example, include pins that can be pressed into the circuit board 150 by means of a spring action.

[0058] The electrical contacts 111 can also be electrically and mechanically connected to the printed circuit board using through-hole technology (THT). For example, the electrical contacts 111 can have wire leads that can be inserted through contact holes in the printed circuit board 150 during assembly and then soldered to the conductor track.

[0059] The current-carrying contact piece 120 protrudes from the mounting plate 112 of the busbar 110 in a material-bonded manner and is designed to establish a mechanical and electrical contact with a contact element such as a cable lug, for example a cable lug 210, as shown in the Fig. 4 and Fig. 5 shown.

[0060] The plug-in base 101 is made, for example, of plastic or another electrically insulating material. The busbar 110 is, for example, enclosed by the plug-in base 101 in the area between the first end 110a and the second end 110b of the busbar 110, as shown in Fig. 1 can be seen.

[0061] The support plate 112 of the busbar 110 can, as in Fig. The busbar 110 is shown in Figure 1, enclosed laterally by the socket 101, overmolded, or inserted into the socket 101. The mounting plate 112 of the busbar 110 protrudes upwards from the socket 101 and is freely accessible for placing and securing the cable lug. The electrical contacts 111 protrude downwards from the socket 101 and are freely accessible for insertion into corresponding mating contacts on the circuit board 150 (not shown in Figure 1). Fig. 1) to be plugged in. The socket 101 is hollow below the contact surface 102 of the plug socket 101. This cavity can be used, when the plug socket 101 is plugged into the circuit board 150, to accommodate additional components on the circuit board 150. In the exemplary embodiment of the Fig. In version 1, the plug socket 101 has only two sides where it is mechanically fixed to the circuit board 150. However, instead of two sides, the plug socket 101 can also be mechanically attached to the circuit board 150 on three or four sides.

[0062] The busbar 110 is in the exemplary embodiment of the Fig. The busbar 110 is bent so that, when the socket 101 is inserted, the first end 110a of the busbar 110 is approximately orthogonal to the circuit board 150 and the second end 110b of the busbar 110 is approximately parallel to the circuit board 150. Approximately orthogonal to the circuit board 150 means at an angle of 90 degrees to the circuit board 150, including a tolerance range of, for example, plus / minus 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, or 20 degrees. Approximately parallel to the circuit board 150 means at an angle of 0 degrees to the circuit board 150, including a tolerance range of, for example, plus / minus 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, or 20 degrees.

[0063] The plug-in base 101, for example, comprises a plurality of plug-in pillars 103, as in Fig. 1 shown, which are designed for inserting the plug socket 101 into the circuit board 150 in order to detachably attach the plug socket 101 to the circuit board 150.

[0064] In Fig. Figure 1 shows an exemplary number of three pegs 103, but there can also be more than three, for example 4, 5, 6, 7, 8, 9 or more. The pegs 103 can be attached to the corners of the peg base 101, as shown in Fig. Figure 1 shows how high stability is ensured, or on the wall sides between two respective corners. The plug-in pillars 103 are made of the same material as the plug-in base 101, for example plastic, or they can also be made of a different material, for example a more stable plastic, such as fiberglass-reinforced plastic or similar.

[0065] In one embodiment, the current-carrying contact element 120 is a contact bolt, as in Fig. Figure 1 shows the part protruding from the support plate 112 of the busbar 110. Fig. Figure 1 shows how the contact bolt 120 protrudes upwards, vertically, or perpendicularly from the support plate 112. The contact bolt 120 can, for example, be welded, soldered, glued, or attached to the support plate 112 using another joining technique that creates a material-bonded connection.

[0066] The current-carrying contact bolt 120 can, for example, be a threaded bolt designed to mechanically and electrically connect the cable lug 210 to the mounting plate 112 of the busbar 110 via a screw connection 220, as for example in the Fig. 4 and Fig. 5 shown in more detail.

[0067] In one embodiment, the current-carrying contact element 120 is a contact flag (not shown in the figures) which, for example, protrudes laterally from the support plate 112 of the busbar 110.

[0068] The cable lug 210 can be attached to the mounting plate 112 of the busbar 110 in different exit directions 230, as for example in the Fig. 4 and Fig. Figure 5 shows that the cable lug 210 can be attached to the mounting plate 112 at angles of 0 degrees, 90 degrees, 180 degrees, and 270 degrees. Intermediate positions are also possible, such as 10 degrees, 45 degrees, etc., where the cable lug or the cable attached to it protrudes beyond the corners of the mounting plate 112.

[0069] The support plate 112 can be rectangular, as shown in Fig. 1 is shown, but it can also take on any other geometric shape, for example square, triangular, hexagonal, circular, oval, etc.

[0070] The printed circuit board contact socket 100 can further include a heat sensor (not shown in the figures) which can be attached to the plug socket 101 and is configured to detect the temperature of the busbar 110. This allows a short circuit to be effectively detected.

[0071] Fig. Figure 2 shows two 3D representations of the printed circuit board contact socket 100. Fig. 1 in two further views.

[0072] The PCB contact socket 100 corresponds to the PCB contact socket 100 from Fig. 1. Contrary to the view from Fig. 1 are the views in Fig. Figure 2 is rotated 180 degrees, and circuit board 150 is not shown. The circuit board contact socket is essentially "upside down." The electrical contacts 111 of the busbar 110, which are inserted into circuit board 150, are visible on the top side. Also visible on the top side are the support pillars 103, which are slightly tapered on the top side to create a non-conductive connection with circuit board 150.

[0073] The current-carrying contact piece 120, which is designed as a threaded bolt, can be seen on the underside of both views. The cable lug can be connected there.

[0074] In the views of Fig. Figure 2 shows that the socket 101 forms a cavity below the contact surface 102, or, in these illustrations, above the contact surface 102. This cavity can be used, when the socket 101 is inserted, to accommodate additional electronic components on the circuit board.

[0075] Fig. Figure 3 shows two 3D representations of the printed circuit board contact socket 100. Fig. 1 in two further views.

[0076] The PCB contact socket 100 corresponds to the PCB contact socket 100 from Fig. 1. As already mentioned in Fig. 2, are contrary to the view from Fig. 1 the views in Fig. Figure 3 is rotated 180 degrees, and the circuit board 150 is not shown. The electrical contacts 111 of the busbar 110, which are inserted into the circuit board 150, can be seen on the top side. Also visible on the top side are the support pillars 103, which are inserted into the circuit board 150 to support the socket 101 on the circuit board 150.

[0077] In contrast to the views of Fig. 2 are the views of Fig. 3 rotated around the vertical. The vertical here is the axis that runs in the longitudinal direction of the contacting bolt 120.

[0078] Fig. Figure 4 shows a 3D representation of a composite of 200 consisting of printed circuit board contact sockets 100 accordingly. Fig. 1 with cable lug 210 and cable 212 according to one embodiment.

[0079] The assembly 200 includes a printed circuit board contact socket 100 as described above. Fig. 1 to 3 described, a cable lug 210 which is electrically and mechanically attached to the current-carrying contact piece 120 of the printed circuit board contact base 100, and a cable 212 which protrudes from the cable lug 210 in an exit direction 230.

[0080] The cable lug 210 is a metal part used to connect a cable to an electrical device or, in this case, a circuit board. As in Fig. As shown in Figure 4, the cable lug 210 comprises on one side a contact surface or terminal plate 211 with a central opening, which can be inserted over the contact pin 120 of the printed circuit board contact socket 100 and mechanically and electrically fastened to it via a screw connection 220. On the other side, the cable lug 210 has a clamping element 213, for example made of bent sheet metal, which can be pulled over the cable 212 to clamp the cable 212 and ensure mechanical and electrical contact. The cable lug 210 can, for example, be made from a cut or stamped and bent sheet metal, as shown here in Figure 4. Fig. Figure 4 shows the following. The outgoing direction 230 of the cable lug 210 corresponds here to the direction in which the longitudinal axis of the cable 212 extends from the cable lug 210 or the clamping piece 213 of the cable lug. Instead of a cable, a busbar, for example a round busbar, can also be attached to the cable lug 210. However, it is also possible to attach a flat busbar (not shown) with the cable lug 210.

[0081] Fig. Figure 5 shows a top view of the 200-unit complex. Fig. 4.

[0082] In the top view, the printed circuit board contact socket 100 can be seen at the top of the drawing, and the cable 212 runs towards the bottom of the drawing from 230. The cable lug 210 clamps the cable 212 and secures it to the printed circuit board contact socket 100 via a screw connection, which provides contact to the printed circuit board (not shown in Fig. 5) can be produced.

[0083] Fig. Figure 6 shows a top view of the printed circuit board contact socket 100. Fig. 1 and a top view of a multi-circuit board contact socket 300a according to an exemplary first embodiment.

[0084] The PCB contact socket 100 corresponds to the PCB contact socket 100 from the Fig. 1 to 3. It is shown here in top view, analogous to the representation in Fig. 5.

[0085] In the lower part of Fig. Figure 6 shows a multi-circuit board contact socket 300a, which serves to contact a plurality of cable lugs to a circuit board. The multi-circuit board contact socket 300a comprises an exemplary number of four circuit board contact sockets 100 according to the Fig. 1 to 3 or the upper part of Fig. 6. The four printed circuit board contact sockets 100 are arranged side by side. The contact surfaces 102 of the respective plug sockets 101 of the four printed circuit board contact sockets 100 are arranged parallel to each other.

[0086] The contact surfaces 102 of the plug sockets 101 of the four printed circuit board contact sockets 100 can be arranged at the same or different heights above the printed circuit board 150 when the plug sockets 101 are inserted.

[0087] Instead of an exemplary number of four PCB contact sockets 100, any other number of PCB contact sockets 100 is also feasible.

[0088] Fig. Figure 7 shows top views of the multiple printed circuit board contact sockets 300b, 300c, 300d according to the invention, in accordance with exemplary second, third and fourth embodiments.

[0089] The multi-circuit board contact sockets 300b, 300c, 300d are used to contact a multiple of contact parts such as cable lugs with a circuit board.
