Printed circuit board, interconnect system and method

Description

[0001] The invention relates to a printed circuit board for making contact with a connector system on the card side and / or the computer side, as well as a connector system comprising such a printed circuit board. The connector system is designed to connect a PCB card to a central computer of a motor vehicle.

[0002] Modern motor vehicles are equipped with a central computer that can run or control various automotive applications. For this purpose, the motor vehicle's central computer can be connected, similar to the motherboard of a PC or notebook, to a PCB (printed circuit board) or a chip card specific to the respective application. Therefore, it is necessary to provide a connector system suitable for the automotive sector between a PCB card and the motor vehicle's central computer.

[0003] The state of the art includes network plugs and connectors from the telecommunications sector, but they are not designed or suitable for the automotive sector. Furthermore, there are multi-pin connectors that feature a plurality of individual metal sheets for shielding the contact elements. However, such connectors are not suitable for mass production and, for this reason alone, are not suitable for the automotive sector.

[0004] Such a connector system is designed, among other things, to transmit differential pair signals via differential pair contact elements. These differential pair signals must be routed on both the computer and card sides in such a way that a plurality of differential pair signals can be transmitted reliably.

[0005] Document WO 2015 / 112773 A1 discloses a modular electrical connector with a rectangular intermediate part. The connector is used to contact a PCB on which routing channels are formed between contact points arranged in rows and columns.

[0006] From the document US 2012 / 0214344 A1, a broad-side coupled connector is known in which differential pair contacts arranged in rows and columns are tilted by 40° to 60° relative to these rows and columns.

[0007] Document US 2010 / 0144203 A1 describes a backplane connector system capable of operating at frequencies of up to 25 Gbps. Contacts protrude from the connector in rows and columns. The contacts of a column are routed on a PCB on both sides of the column.

[0008] It is therefore an object of the present invention to enable secure routing for a connector system for connecting a PCB card to a central computer of a motor vehicle, which meets the requirements of the automotive sector, in particular with regard to stability, signal quality, frequency range of signal transmission, and / or mass production suitability. These objects are achieved by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0009] A first aspect relates to a printed circuit board for making contact with a connector system on the card side and / or the computer side, wherein the connector system is designed to connect a PCB card to a central computer of a motor vehicle, and wherein differential pair signals can be conducted, i.e., routed, along differential pair contact elements of the connector system through the connector system. The printed circuit board has a plurality of pair contact points for contacting differential pair contact elements of the connector system, wherein each pair contact point has two individual contact points for contacting individual contact elements of the respective differential pair contact element of the connector system. Furthermore, the printed circuit board has at least one first routing channel, through which conductor tracks are routed to the individual contact points of at least one of the pair contact points.A first group of pair contact points is arranged one behind the other in a first row on the circuit board, and a second group of pair contact points is arranged one behind the other in a second row on the circuit board, wherein the second row is arranged and / or aligned approximately parallel to the first row. Conductor tracks are routed, i.e., routed, through the first routing channel to the two individual contact points of at least one of the pair contact points of the first group. The first routing channel is arranged between the first row and the second row such that it is arranged approximately parallel to the first and second rows.

[0010] The circuit board can contact the connector system either on the card side or on the computer side. If the circuit board contacts the connector system on the card side, the circuit board can be designed, for example, as the exact PCB card to which the connector system connects the vehicle's central computer. However, the circuit board can also contact the connector system on the computer side, in which case it can be designed, for example, as a component of the central computer and / or be electrically connected to it. In general, the circuit board can be designed as a PCB card.

[0011] Differential pair signals are transmitted via two individual contact elements of a differential pair contact element of the connector system, usually arranged adjacent to each other. The two individual contact points of each pair contact point are designed to electrically contact these two individual contact elements of a differential pair contact element of the connector system. The circuit board can each have a hole at the individual contact points to accommodate the associated contact element of the connector system. The pair contact points are designed for electrical and / or mechanical bonding of the differential pair contact elements of the connector system.

[0012] The circuit board's tracks are electrically conductive and designed to transmit differential pair signals. To do this, the tracks electrically contact the pair contact points; more precisely, each track contacts exactly one individual contact point of each pair contact point. To achieve this, the circuit board has (at least) twice as many tracks as pair contact points.

[0013] The two individual contact points of each pair contact point are arranged adjacent to one another on the circuit board. Furthermore, they are arranged at a distance from one another to reduce crosstalk of differential pair signals. The two individual contact points of each pair contact point can be arranged at a distance from one another on the circuit board in the same direction, e.g., in a direction perpendicular to the row direction in which the first and second rows of pair contact points are aligned. In other words, the individual contact points can be arranged adjacent to one another in the column direction, with the column direction being approximately perpendicular to the row direction.

[0014] Both the row direction and the column direction are arranged parallel to the circuit board plane in which the circuit board is formed.

[0015] At least the first and the second row of pair contact points are formed on the circuit board, wherein the circuit board can also have more than two such rows of pair contact points. Each row of pair contact points has a plurality of pair contact points, e.g. at least two or at least three, preferably exactly four pair contact points. All rows of pair contact points on the circuit board can be aligned approximately parallel to one another in the row direction and / or have the same number of pair contact points. Each row of pair contact points forms a group of pair contact points, e.g. the first row forms the first group, the second row forms the second group, and if necessary so on.

[0016] In total, the circuit board can have between approximately 10 and approximately 100 pair contact points arranged in such rows, preferably between approximately 25 and approximately 70, and particularly preferably between approximately 40 and 60 pair contact points. In one embodiment, the circuit board can have exactly 48 pair contact points arranged in 12 rows, with each row having exactly four pair contact points. Each row of pair contact points can be assigned exactly one routing channel.

[0017] The first routing channel is located between the first and second rows of pair contact points. Conductor tracks are routed, or at least partially routed, through the routing channel. The two conductor tracks that contact the two individual contact points of at least one pair contact point in the first row are preferably routed through the first routing channel. Alternatively, these two conductor tracks can also be routed through different routing channels, although this is not always ideal when transmitting differential pair signals.

[0018] The conductor tracks are designed such that they initially extend (in a transition region, so to speak) from the pair contact point into the first routing channel, and then, within the first routing channel, parallel and adjacent to the first row up to at least one connection end of the first row, at which the first row of pair contact points ends. The first routing channel can be approximately as long as the first row, so that even the pair contact point furthest from the connection end can be routed through the first routing channel.

[0019] The first routing channel can be approximately rectilinear, at least in sections, namely at least in its section arranged between the first and second row of pair contact points. The first routing channel thus also extends in the row direction on the circuit board. The first routing channel can be arranged directly adjacent to the first row of pair contact points on the circuit board, i.e. no further elements of the circuit board are arranged between the first row of pair contact points and the first routing channel. Likewise, the second row of pair contact points can be arranged directly adjacent to the first routing channel, i.e. the first routing channel is arranged exactly parallel to and between the first and second row of pair contact points.

[0020] The first routing channel provides a particularly advantageous way to reliably and efficiently route the connector system's differential pair signals. The first routing channel is suitable for reliably routing a large number of differential pair signals transmitted by the connector system within a confined space.

[0021] According to one embodiment, the conductor tracks are routed through the first routing channel at least to a connection end of the first row. In this case, the first routing channel can be at least approximately as long as the first row. The first routing channel thus extends from the pair contact point to which the conductor tracks lead through the first routing channel, at least to a connection end of the first row. This allows the differential pair signals to be reliably routed from the rows and / or the matrix (which is specified by the connector system) of pair contact points into a free circuit board area. This free circuit board area can be arranged outside the area of ​​the circuit board that is directly contacted by the connector system and therefore provide more space to reliably transmit the differential pair signals.

[0022] According to one embodiment, conductor tracks to the individual contact points of a plurality of pair contact points of the first group are routed through the first routing channel. The conductor tracks to the pair contact points can be routed side by side and / or one above the other through the first routing channel. According to one embodiment, conductor tracks to the two individual contact points of all pair contact points of the first group that are not arranged at a connection end of the first row, to which the conductor tracks are routed away from the individual contact points through the routing channel, are routed through the first routing channel. In other words, almost all pair contact points are routed completely through the first routing channel, with the exception of the pair contact point that is already arranged at the connection end.This last pair contact point can either be routed through the first routing channel or directly into the free circuit board space at the end of the connection. Preferably, this last pair contact point at the end of the connection is no longer routed through the routing channel to avoid congestion. This enables particularly efficient routing for multiple differential pair signals.

[0023] According to the invention, the conductor tracks to the individual contact points of the plurality of pair contact points of the first group are routed one above the other through the first routing channel in several levels, preferably in at least three levels. This is particularly space-saving and reduces the required width of the first routing channel (in the column direction) between the first and second row of pair contact points.

[0024] According to a further development, an electrical shield is formed between the levels in which the conductor tracks to the two individual contact points of the different pair contact points of the first group are routed one above the other through the first routing channel. The electrical shield reduces interference between the differential pair signals at the pair contact points of the first group while they are transmitted along the first routing channel.

[0025] According to one embodiment, the circuit board has a second routing channel through which conductor tracks are routed to the (e.g. two) individual contact points of at least one of the pair contact points of the second group, wherein the second routing channel is arranged adjacent to the second row such that it is arranged approximately parallel to the first and second rows. The second routing channel can be constructed essentially identically to the first routing channel, i.e. in particular can have all (e.g. optional) features that the first routing channel can also have. The second routing channel can be arranged, for example, between the second row of pair contact points and a third row of pair contact points. The second routing channel can be designed to route the differential pair signals that are transmitted via the pair contact points of the second group.This allows the differential pair signals of each group of pair contact points to be safely routed on the circuit board.

[0026] According to one embodiment, the circuit board has a predetermined number of rows of pair contact points, which are arranged approximately parallel to one another on the circuit board. Each row of pair contact points is assigned exactly one routing channel, through which conductor tracks are led to all pair contact points of the assigned row that are not arranged at a connection end of this row. These routing channels are arranged approximately parallel to the rows of pair contact points. The rows of pair contact points and these routing channels are each arranged alternately next to one another, with the respectively assigned routing channel being formed next to each row of pair contact points. The number of rows can be, for example, at least four, preferably at least six or ten. In particular, the number of rows can be exactly twelve.The routing channels and rows of pair contact points are arranged alternately next to each other in the column direction on the circuit board, similar to the dark and light stripes of a zebra crossing. A first routing channel assigned to the first row is arranged directly between the first and second rows of pair contact points, the second routing channel assigned to the second row of pair contact points is arranged directly between the second and third rows of pair contact points, and so on. All rows of pair contact points and all of these routing channels can be approximately the same length in the row direction and / or extend to a terminal end.

[0027] According to one embodiment, the circuit board has at least ten rows of pair contact points, each of which is assigned at least one routing channel. In the previous embodiment, this can mean, for example, that the predetermined number of rows is at least ten. This allows a particularly large number of differential pair signals to be reliably routed.

[0028] According to one embodiment, each row of pair contact points has at least four pair contact points. This also allows a particularly large number of differential pair signals to be reliably routed.

[0029] According to one embodiment, the printed circuit board is designed as the PCB card to which the connector system connects the central computer of the motor vehicle, e.g. as a component of the central computer.

[0030] According to an alternative embodiment, the circuit board is designed for contacting the connector system on the computer side.

[0031] According to one embodiment, the circuit board has power contact points arranged next to the rows in which the pair contact points are formed, for contacting power contact elements of the connector system on the card side and / or the computer side. Depending on whether the circuit board is designed for contacting the connection system on the card side or the computer side, the power contact points are also designed for corresponding contact with power contact elements of the connector system. The power contact points can, for example, be formed adjacent to the pair contact points on the circuit board in the column direction.

[0032] According to one embodiment, the circuit board has single-end contact points arranged next to the rows in which the pair contact points are formed, for contacting single-end contact elements of the connector system on the card side and / or the computer side. Depending on whether the circuit board is designed for contacting the connection system on the card side or the computer side, the single-end contact points are also designed for corresponding contacting of single-end contact elements of the connector system. The single-end contact points can, for example, be formed adjacent to the pair contact points on the circuit board in the column direction.

[0033] In a further development of at least one of the two preceding embodiments, the power contact points and / or the single-end contact points are arranged in rows that are arranged approximately parallel to the rows in which the pair contact points are formed. In other words, the rows of power contact points and / or single-end contact points are also arranged one behind the other in the row direction. Analogous to the routing channels for the pair contact points, the circuit board can also have power routing channels and / or single-end routing channels, each of which is arranged adjacent to and parallel to an associated row of power contact points and / or single-end contact points. These power routing channels and / or single-end routing channels can be designed analogously to the routing channels for the pair contact points and, in particular, also have the optional features of these routing channels.

[0034] One aspect relates to a connector system for connecting a PCB card to a central computer of a motor vehicle, comprising a computer-side connector element with a plurality of computer-side differential pair contact elements and a card-side connector element with a plurality of card-side differential pair contact elements, with at least one printed circuit board according to the preceding aspect for contacting the card-side and / or computer-side differential pair contact elements on the card side and / or computer side. Details of the card-side and computer-side connector elements are described in more detail below.

[0035] According to one embodiment, the computer-side differential pair contact elements of the computer-side connector element contact a first circuit board according to the preceding aspect and the card-side differential pair contact elements of the card-side connector element contact a second circuit board according to the preceding aspect as the PCB card.

[0036] According to one embodiment, the computer-side connector element comprises: a computer-side zinc die-cast housing with at least one computer-side contact cavity; at least one computer-side insulating body, which in the assembled state is arranged within the at least one computer-side contact cavity; and a plurality of computer-side contact elements, which in the assembled state are arranged at least partially within computer-side insulating cavities in the at least one computer-side insulating body.

[0038] In the context of this description, the term "connection" refers specifically to an electrical connection. It can also include a physical connection. A "computer-side connector element" is understood to mean a connector element that is designed to be connected (electrically and / or physically) directly to a central computer. Similarly, a "card-side connector element" is understood to mean a connector element that is designed to be connected (electrically and / or physically) directly to a PCB card. In general, the additional designation "computer-side" for various elements indicates that these computer-side elements belong to the computer-side connector element and / or are a component thereof.Accordingly, the additional designation "card-side" for various elements indicates that these card-side elements belong to and / or are part of the card-side connector element.

[0039] For the purposes of this description, the assembled state of the connector system refers to a state in which the connector system, the computer-side connector element, and / or the card-side connector element are used as intended and / or are mounted, assembled, or plugged together as intended. In particular, the assembled state refers to the fact that the computer-side and card-side connector elements are electrically connected to one another. The assembled state can therefore also be referred to as the assembled state, the assembled state, the plugged-together state, and / or the operating state. In other words, the assembled state of a connector element or connector system refers to a proper arrangement or installation position of the individual elements of the connector element and / or connector system.

[0040] The PCB card can be designed, in particular, as a PCMCIA Express 3.0 and / or 4.0 card. The term "PCB card" can also refer to other chip cards that are generally suitable for use in the automotive sector.

[0041] The computer-side connector element has a computer-side die-cast zinc housing. The computer-side die-cast zinc housing has at least one computer-side contact cavity, preferably a plurality of computer-side contact cavities. The computer-side contact cavity(ies) are formed as recesses in the die-cast zinc housing. Each computer-side contact cavity forms a computer-side contact opening. In other words, the computer-side die-cast zinc housing is formed and / or manufactured, in particular in one piece, from die-cast zinc. The die-cast zinc material is preferably formed from a zinc alloy, in particular the alloy ZP0410, ZP0400 and / or ZP0430. These alloys are known, for example, from the EN 12844 standard and described therein. Alternatively, the computer-side die-cast zinc housing can be formed from a different die-cast zinc material.In particular, the computer-side die-cast zinc housing is formed in one piece, meaning it is not composed of multiple parts, but rather comprises a single part made of a die-cast tin material. If the computer-side housing has a plurality of contact cavities, these can be arranged in the form of a matrix, at least in some areas, within the computer-side housing. The computer-side die-cast zinc housing can provide shielding and ensure high signal quality.

[0042] The computer-side connector element has at least one computer-side insulating body. The computer-side connector element can also have a plurality of computer-side insulating bodies. The computer-side insulating body(ies) has(have) a plurality of computer-side insulating cavities. One of the computer-side insulating bodies can either have a plurality of computer-side insulating cavities or exactly one computer-side insulating cavities. In an extreme case, in which the computer-side connector element has exactly one computer-side insulating body, this means that this one computer-side insulating body has all of the computer-side insulating cavities. In another extreme case, in which the computer-side connector element has exactly as many computer-side insulating bodies as computer-side insulating cavities, it means that each computer-side insulating body has exactly one computer-side insulating cavity.In between there are embodiments in which, for example, a group of computer-side insulating bodies each has exactly one computer-side insulating cavity, and one (or more) further computer-side insulating bodies each have several computer-side insulating cavities.

[0043] The computer-side insulating cavity(ies) is / are arranged within the computer-side contact cavity(ies) in the assembled state. Preferably, the at least one computer-side insulating body is formed and / or manufactured from the materials PA9T, PA10T, and / or LCP. The number of computer-side insulating bodies can, for example, correspond to the number of computer-side contact cavities. The computer-side insulating bodies can, for example, be approximately rectangular, which enables simple assembly.

[0044] In addition, the computer-side connector element has a plurality of computer-side contact elements, in particular contact pins. These include the computer-side differential pair contact elements for making computer-side contact with the pair contact points of the circuit board arranged on the computer side. The computer-side contact elements are preferably designed and / or manufactured from CuSn6 or alternative copper alloys. Generally, contact elements are electrical conductors with which electrical signals can be transmitted. In the assembled state, the computer-side contact elements are arranged at least partially within the computer-side insulating cavities of the at least one computer-side insulating body, and thus also within the at least one computer-side contact cavity. In other words, the at least one computer-side insulating body surrounds the computer-side contact elements at least partially.In this context, "at least in some regions" means that at least one section of each computer-side contact element is arranged within a computer-side insulating cavity of the at least one computer-side insulating body and / or that one of the computer-side insulating bodies surrounds at least a section of each computer-side contact element. In particular, the computer-side contact elements, in the assembled state, are arranged at least in some regions within computer-side insulating cavities of the at least one computer-side insulating body, so that they are electrically insulated from the computer-side housing. The computer-side contact elements can penetrate the computer-side housing substantially completely.

[0045] In addition to the insulating effect, the at least one computer-side insulating body is also designed to hold and / or secure the computer-side contact elements in the at least one computer-side contact cavity. Thus, in addition to its insulating function, the at least one insulating body can also have a stability function, i.e., a holding and / or fastening function. Air can be used as an insulator at the points or sections of the contact elements that are not surrounded by an insulating body.

[0046] A plug-in end of the computer-side contact elements can protrude from the computer-side housing and be designed to contact the central computer. In this case, the plug-in ends of the computer-side contact elements can be designed, in particular, to contact the printed circuit board according to the above aspect.

[0047] The card-side connector element has a card-side die-cast zinc housing. The card-side die-cast zinc housing has at least one card-side contact cavity, preferably a plurality of card-side contact cavities. The card-side contact cavity(ies) are formed as a recess in the die-cast zinc housing. Each card-side contact cavity forms a card-side contact opening.

[0048] The card-side zinc die-cast housing can be constructed in two pieces, i.e., it can be composed of exactly two zinc die-cast parts, namely a first card-side zinc die-cast housing and a second card-side zinc die-cast housing. Alternatively, the card-side zinc die-cast housing can also be constructed in one piece. The zinc die-cast material is preferably made of a zinc alloy, in particular the alloy ZP0410, ZP0400, and / or ZP0430. These alloys are known, for example, from the EN 12844 standard and described therein. Alternatively, the card-side zinc die-cast housing can be constructed of a different zinc die-cast material. The card-side zinc die-cast housing can have an (electrical) shielding effect and enable high signal quality.

[0049] If the card-side housing has a plurality of card-side contact cavities, these can be arranged in the card-side housing, at least in some areas, in the form of a matrix, in particular (at least in some areas) complementary to the computer-side contact cavities. In general, an associated or complementary card-side contact cavity can be provided and / or formed for each computer-side contact cavity.

[0050] The card-side connector element has at least one card-side insulating body. The card-side connector element can also have a plurality of card-side insulating bodies. The card-side insulating body(ies) has(have) a plurality of card-side insulating cavities. One of the card-side insulating bodies can have either a plurality of card-side insulating cavities or exactly one card-side insulating cavities. In an extreme case, in which the card-side connector element has exactly one card-side insulating body, this means that this one card-side insulating body has all of the card-side insulating cavities. In another extreme case, in which the card-side connector element has exactly as many card-side insulating bodies as card-side insulating cavities, it means that each card-side insulating body has exactly one card-side insulating cavity.In between there are embodiments in which, for example, a group of card-side insulating bodies each has exactly one card-side insulating cavity, and one (or more) further card-side insulating bodies each have several card-side insulating cavities.

[0051] The card-side insulating cavity(ies) is / are arranged within the card-side contact cavity(ies) in the assembled state. Preferably, the at least one card-side insulating body is formed and / or manufactured from the materials PA9T, PA10T, and / or LCP. The number of card-side insulating bodies can, for example, correspond to the number of card-side contact cavities. The card-side insulating bodies can, for example, be rectangular in shape in some areas, which can enable simple assembly.

[0052] The card-side insulating body(s) have card-side insulating cavities that are designed to accommodate the computer-side contact elements at least in part when mounted. In other words, when mounted, the computer-side contact elements penetrate into the at least one card-side insulating body to contact the card-side contact elements. The number of card-side insulating bodies can correspond to the number of card-side contact cavities. Furthermore, the number of computer-side contact cavities can correspond to the number of card-side contact cavities.

[0053] In addition, the card-side connector element has a plurality of card-side contact elements. These include the card-side differential pair contact elements for making contact with the pair contact points of the card-side printed circuit board. The card-side contact elements are preferably formed or manufactured from CuSn6 or alternative copper alloys. In the assembled state, the card-side contact elements are arranged at least partially within the card-side insulating cavities of the at least one card-side insulating body, and thus also within the at least one card-side contact cavity. In other words, the at least one card-side insulating body surrounds the card-side contact elements at least partially.In this context, the term "at least in some regions" means that at least one section of a card-side contact element is arranged within a card-side insulating cavity of a card-side insulating body and / or that a card-side insulating body surrounds at least one section of a card-side contact element. In particular, the card-side contact elements, in the assembled state, are arranged at least in some regions within card-side insulating cavities of the at least one card-side insulating body, so that they are electrically insulated from the card-side housing. The card-side contact elements are designed and arranged such that, in the assembled state, they contact respective associated computer-side contact elements.The contacting of the computer-side and card-side contact elements takes place, in particular, within the card-side contact cavities and / or within the card-side insulating bodies. Alternatively, the contacting of the computer-side and card-side contact elements can take place within the computer-side contact cavities and / or within the computer-side insulating bodies.

[0054] A plug end of the card-side contact elements may protrude from the card-side housing and be configured to contact the PCB card, which may be configured as the printed circuit board according to the first aspect.

[0055] In addition to the insulating effect, the at least one card-side insulating body can be designed to hold and / or secure the card-side contact elements in the at least one card-side contact cavity. The at least one card-side insulating body can have and / or fulfill both an insulating function and a stability function. Air can be used as an insulator at the locations or sections of the card-side contact elements that are not surrounded by a card-side insulating body.

[0056] In the connector system, the computer-side connector element and / or the card-side connector element each have a die-cast zinc housing, each with at least one contact cavity. This allows for continuous shielding in the assembled state due to the cavities surrounded by the die-cast zinc housings, in which the signal-transmitting contact elements are located. It has been demonstrated that the connector system meets the requirements in the automotive sector listed above. Furthermore, the connector elements and thus the connector system can be manufactured quickly and easily using die-cast zinc, making them suitable for mass production compared to conventional connectors that meet the requirements of the automotive sector. By forming the housings using die-cast zinc, electrical shielding, mass production, and vibration-resistant strength can be achieved.

[0057] One aspect relates to a method for producing a printed circuit board for contacting a connector system on the card side and / or on the computer side, wherein the connector system is designed to connect a PCB card to a central computer of a motor vehicle, and wherein differential pair signals can be conducted through the connector system along differential pair contact elements of the connector system, comprising the steps: Forming a plurality of pair contact points for contacting differential pair contact elements of the connector system, wherein each pair contact point has two individual contact points for contacting individual contact elements of the respective differential pair contact element of the connector system, Forming at least one first routing channel through which conductor tracks are guided to the individual contact points of at least one of the pair contact points; where a first group of the pair contact points is arranged one behind the other in a first row on the circuit board, a second group of the pair contact points is arranged one behind the other in a second row on the circuit board, wherein the second row is arranged approximately parallel to the first row, conductor tracks are led through the first routing channel to the two individual contact points of at least one of the pair contact points of the first group, and the first routing channel is arranged between the first row and the second row such that it is arranged approximately parallel to the first and second row.

[0062] The positional information chosen in this description, such as top, bottom, side, etc., refers to the directly described and illustrated figure and, in the event of a position change, is to be transferred analogously to the new position. The additional designation "computer-side," as used in this description for various elements, means that these elements belong to the computer-side connector element, i.e., a connector element that can be directly connected to the central computer, and / or are designed to be connected to it. Accordingly, the additional designation "card-side" for various elements means that these elements belong to the card-side connector element, i.e., a connector element that can be directly connected to a PCB card, and / or are designed to be connected to it.

[0063] The Figure 1shows a schematic view of a portion of a printed circuit board 200 for electrically contacting the device shown in the following Figures 2 to 4 shown connector system 100.

[0064] Figure 1 shows a region of the printed circuit board 200 which is designed for contacting computer-side and / or card-side differential pair contact elements 13b and / or 33b of the connector system 100, which are described with reference to the following Figures 2 to 4 are described in more detail.

[0065] For this purpose, the printed circuit board 200 has a plurality of pair contact points 210, which are designed for bonding with the computer-side and / or card-side differential pair contact elements 13b and / or 33b of the connector system 100. Each pair contact point 210 has exactly two individual contact points 220, of which Figure 1Only two are identified by way of example. The individual contact points 220 can each have exactly one receptacle (such as a drilled hole) for a plug-in end of the computer-side and / or card-side differential pair contact element 13b and / or 33b of the connector system 100.

[0066] The two individual contact points 220 of each pair of contact points 210 can be arranged on the circuit board 200 at a distance from one another in the column direction S. In this case, the two individual contact points 220 of each pair of contact points 210 can be formed directly adjacent to one another on the circuit board 200, i.e., no further element of the circuit board 200 is formed between these individual contact points 220 (apart from the circuit board material of the circuit board 200 itself).

[0067] The pair contact points 210 of the circuit board 200 are divided into groups. In the Figure 1The section shown shows a first group G1 of pair contact points 210 and a second group G2 of pair contact points 210. Each group of pair contact points 210 has the same, predetermined number of pair contact points 210. In the exemplary embodiment shown, each group of pair contact points 210 has exactly four pair contact points 210.

[0068] All pair contact points 210 of each group are arranged in series, one behind the other. Thus, the four pair contact points 210 of the first group G1 are arranged one behind the other in a first row R1, and the four pair contact points 210 of the second group G2 are arranged one behind the other in a second row R2. The two rows R1 and R2 extend approximately parallel to each other in a row direction R.

[0069] The column direction S and the row direction R are approximately perpendicular to each other and arranged in the extension plane of the circuit board 200.

[0070] In this case, all rows of pair contact points 210 can be of approximately the same length, have the same predetermined number of pair contact points 210 (four in the illustrated embodiment), and / or be arranged spaced apart from one another in the column direction S. Furthermore, they can be arranged at the same height next to one another on the circuit board 200, so that two pair contact points 210 of adjacent rows are arranged one behind the other in the column direction S, forming columns, so to speak.

[0071] These columns of pair contact points 210 are interrupted by routing channels 230, 232 arranged between the rows R1, R2.

[0072] The rows of pair contact points 210 all end at a connection end 250. Thus, the first row R1 and the second row R2 extend away from the connection end 250 against the row direction R along the surface of the printed circuit board 200. The connection end 250 can be adjacent to a free circuit board area of ​​the printed circuit board 200. In this free circuit board area, no contact element of the connector system 100 is contacted any more, so that in this free circuit board area more space is available for routing the differential pair signals than between the individual pair contact points 210. Therefore, routing in this adjacent free circuit board area is no longer possible. Figure 1 shown, but can be designed conventionally and / or application-specifically.

[0073] In the section of the printed circuit board 200 shown, a first routing channel 230 is arranged between the first row R1 and the second row R2 of pair contact points 210. Furthermore, a second routing channel 232 is arranged on the side of the second row R2 facing away from the first routing channel 230. The second routing channel 232 can, for example, be arranged between the second row R2 and another, no longer in Figure 1 shown, third row of pair contact points 210 may be formed.

[0074] The first routing channel 230 is configured to route conductive traces 240 that can transmit differential pair signals from and / or to the individual contacts 220 of a pair contact point 210 of the first row R1. Figure 1Only two conductive traces 240 are shown through the first routing channel 230, which lead to the individual contacts 220 of the pair contact point 210 located furthest from the connection end 250. These two conductive traces 240 are arranged in the same plane.

[0075] In Figure 1 It is no longer shown that conductor tracks 240 to the two middle pair contact points 210 of the first row R1 are also routed through the first routing channel 230. These conductor tracks to the two middle pair contact points 210 are each routed in a different plane through the first routing channel 230, e.g., separated from each other by a shield.

[0076] In general, conductor tracks 240 can be routed through the first routing channel 230 to all individual contacts 220 of the pair contact points 210 of the first row R1 that are not formed directly at the connection end 250. The pair contact point 210 arranged directly at the connection end 250 can also be routed outside the first routing channel 230 into the adjacent free circuit board area.

[0077] Likewise, the second routing channel 232 is configured to route conductive traces 240 that can transmit differential pair signals from and / or to the individual contacts 220 of a pair contact point 210 of the second row R2. Figure 1 Only two conductive traces 240 are shown through the second routing channel 232, which lead to the individual contacts 220 of the pair contact point 210 located furthest from the connection end 250. These two conductive traces 240 are arranged in the same plane.

[0078] In Figure 1It is no longer shown that conductor tracks 240 to the two middle pair contact points 210 of the second row R2 are also routed through the second routing channel 232. These conductor tracks to the two middle pair contact points 210 can each be routed through the second routing channel 232 in a different plane, e.g., separated from each other by a shield.

[0079] Just as with the first routing channel 230, conductor tracks 240 can also be routed through the second routing channel 232 to all individual contacts 220 of the pair contact point 210 of the second row R2 that are not formed directly at the connection end 250.

[0080] The same applies to non- Figure 1 shown additional routing channels for electrical contact with other, not in Fig. 1 shown rows of pair contact points 210.

[0081] The routing channels 230, 232 extend essentially in a straight line from a row end of the rows R1, R2 of pair contact points 210 facing away from the connection end 250 to the connection end 250.

[0082] In this case, all routing channels and rows of pair contact points 210 can be aligned approximately parallel to one another in the row direction R, and each arranged alternately in the column direction S such that the routing channel assigned to a row is arranged adjacent to the assigned row.

[0083] The arrangement of the routing channels and pair contact points 210 on the circuit board is coordinated with the arrangement of the computer-side and / or card-side differential pair contact elements 13b, 33b of the connector system 100, which is described in more detail below.

[0084] The Figure 2shows a perspective exploded view of a schematic sketch of a connector system 100 without the printed circuit board 200. In this exploded view, a computer-side connector element 10 and a card-side connector element 30 of the connector system 100 are shown separately, i.e., in a non-mated state. In the fully assembled state, the computer-side connector element 10 and the card-side connector element 30 are connected to one another, i.e., plugged together along a first assembly direction M1 indicated by an arrow.

[0085] The computer-side connector element 10 is designed to be connected or plugged into a central computer of a motor vehicle (not shown) with a computer-side plug-in side 14 at the front, e.g. into the Figure 1printed circuit board 200 shown. In the illustrated embodiment, the plug-in side 14, in the assembled state, is the side of the computer-side connector element 10 that faces away from the card-side connector element 30. A normal to the computer-side plug-in side 14 is arranged approximately opposite and parallel to the first mounting direction M1.

[0086] The computer-side connector element 10 has a plurality of contact elements 13a, 13b and 13c, which can be connected via the circuit board 200 to complementary contact elements of the central computer. In the embodiment of the Figure 2The connector system 100 or the computer-side connector element 10 (and analogously the card-side connector element 30) has three different contact areas, namely a single-end contact area with a plurality of single-end contact elements 13a, a differential-pair contact area with a plurality of differential-pair contact elements 13b, and a power contact area with a plurality of power contact elements 13c. While the single-end contact elements 13a each transmit signals or information via only one electrical conductor, the differential-pair contact elements 13b each use two electrical conductors to transmit a differential signal between these two conductors. In the illustrated embodiment, the power contact elements 13c are designed in pairs, similar to the differential-pair contact elements, and are used for power transmission.

[0087] The computer-side connector element 10 has a computer-side housing 20 with a plurality of computer-side contact cavities 11a, 11b, and 11c, namely a computer-side single-pair contact cavity 11a, a plurality (here exactly 48) computer-side differential-pair contact cavities 11b, and a computer-side power contact cavity 11c. All contact cavities 11a-11c are formed extending through the computer-side housing 20 and thus completely penetrate the computer-side housing 20. The contact cavities 11a-11c have (in the first assembly direction M1, see below) an approximately constant cross-section, which is, for example, approximately rectangular. Furthermore, the computer-side connector element 10 has a plurality of computer-side insulating bodies 12a, 12b and 12c, which each form and enclose at least one insulating space which is formed extending through the computer-side housing 20.

[0088] The insulating bodies 12a, 12b, and 12c are arranged within the computer-side contact cavities 11a-11c. In the illustrated embodiment, the computer-side connector element 10 comprises a computer-side single-pair insulating body 12a, a plurality (here exactly 48) computer-side differential-pair insulating bodies 12b, and a computer-side power insulating body 12c.

[0089] In the assembled state, the computer-side contact elements 13a-13c are arranged, at least in some regions, within computer-side insulating cavities of the respective computer-side insulating bodies 12a-12c. Thus, the single-end contact elements 13a are arranged in the single-end contact cavity 11a and within insulating cavities of the single-end insulating body 12a. The differential pair contact elements 13b are each arranged in associated differential pair contact cavities 11b and within associated insulating cavities of the differential pair insulating body 12b. The power contact elements 13c are arranged in the power contact cavity 11c and each within associated insulating cavities of the power insulating body 12c.

[0090] The computer-side housing 20 can have at least one screw opening 22, in the illustrated embodiment, exactly two screw openings 22. Each screw opening 22 is formed integrally with the housing 20 as a die-cast zinc component. The screw openings 22 are formed on an edge of the computer-side plug-in side 14 of the computer-side housing 20. Each screw opening 22 has a circular border surrounding a hollow cylinder section into which a screw can be screwed. The cylinder axis of the hollow cylinder section is arranged approximately parallel to the first mounting direction M1 and / or to the card-side contact elements 13a-13c. Thus, the computer-side housing 20 can be attached to the central computer (not shown) by means of screws screwed into the screw openings 22. The screws are screwed through the screw openings approximately parallel to the computer-side contact elements 13a-13c.This strengthens and / or secures the attachment of the computer-side connector element 10 to the central computer.

[0091] The card-side connector element 30 is designed to be connected to a PCB card along a second mounting direction M2. The PCB card can be, for example, the Figure 1shown circuit board 200 can be provided. For this purpose, the card-side connector element 30 has, on its underside, the card-side plug-in side 34, corresponding card-side contact elements 33a-33c (not shown in the figures) to the computer-side contact elements 13a-13c. The card-side contact elements are formed approximately at right angles, with a first section extending approximately parallel to the first mounting direction M1, and a second section extending approximately parallel to the second mounting direction M2. The second section of the card-side contact elements can protrude from the card-side plug-in side 34 for (electrical and / or physical) contact with the PCB card, i.e., for example, the circuit board 200.

[0092] As in the Figure 2As shown, the second mounting direction M2 is oriented substantially perpendicular to the first mounting direction M1. The card-side connector element 30 is designed and provided to be fastened, e.g., soldered, to the PCB card (not shown) with its card-side plug-in side 34 facing forward in the direction of the second mounting direction M2. In the mounted state, the card-side plug-in side 34 is arranged in a plane that is approximately perpendicular to the plane in which the computer-side plug-in side 14 is arranged.

[0093] The card-side connector element 30 has a card-side housing 40 with a plurality of card-side contact cavities 31a-31c. The card-side housing 40 can be formed in one piece or can have at least two card-side housing elements that can be connected or plugged together.

[0094] The card-side housing 40 has a plurality of card-side insulating bodies 32a-32c, which, in the assembled state, are arranged within the card-side contact cavities 31a-31c. The card-side insulating bodies 32a-32c, in turn, have card-side insulating cavities that are designed to at least partially accommodate associated computer-side contact elements 13a-13c in the assembled state. Both the card-side contact cavities 31a-31c, the card-side insulating bodies 32a-32c, and the card-side contact elements are angled. The card-side contact cavities 31a-31c, etc., have a first section that is approximately parallel to the first assembly direction M1 and a second section that is approximately parallel to the second assembly direction M2.

[0095] In the illustrated embodiment, the card-side connector element 30 comprises a card-side single-pair insulating body 32a, a plurality (here exactly 48) card-side differential-pair insulating bodies 32b, and a card-side power insulating body 32c. The card-side contact elements (not shown in Figure 2In the assembled state, the contact elements (shown in the drawing) are arranged at least partially within card-side insulating cavities of the respective associated card-side insulating bodies 32a-32c. Single-end contact elements are arranged in the single-end contact cavity 31a and within insulating cavities of the single-end insulating body 32a. Differential pair contact elements are arranged in respective differential pair contact cavities 31b and within associated insulating cavities of the differential pair insulating body 32b. Power contact elements are arranged in the power contact cavity 31c and within associated insulating cavities of the power insulating body 32c.

[0096] In the assembled state, in which the computer-side connector element 10 is connected and / or plugged together with the card-side connector element 30, the computer-side contact elements 13a-13c and the card-side contact elements contact each other in the card-side contact cavities 31a-31c and in the insulating cavities of the card-side insulating bodies 32a-32c.

[0097] The computer-side housing 20 can have a plurality of stabilizing elements, while the card-side housing 40 can have a corresponding number of complementary stabilizing elements. When the computer-side connector element 10 and the card-side connector element 30 are plugged together, the stabilizing elements engage with each other and stabilize the plug connection in the assembled state. In addition, the stabilizing elements can also serve as a plug-in aid.

[0098] The card-side housing 40 can also have at least one guide element 52, e.g., a projection that engages a complementary guide element 54 of the computer-side housing 10 when the computer-side connector element 10 and the card-side connector element 30 are plugged together. One of the guide elements 52 can be elongated, aligned approximately parallel to the first assembly direction M1, and / or tapered toward the associated connector element 10 or 30. This facilitates the alignment of the computer-side and card-side connector elements 10 and 30 during plugging together, thus facilitating the assembly of the connector system 100.

[0099] The computer-side housing 20 and the card-side housing 40 can each be formed and manufactured from die-cast zinc, in which the contact cavities 12a-12c and 32a-32c, respectively, are provided. This can ensure that the computer-side contact elements 13a-13c and the card-side contact elements are not only mechanically protected but also electrically shielded to reduce and / or prevent electromagnetic interference. The signal quality can thus be significantly improved.

[0100] Furthermore, the card-side housing 40 can have a spring element that electrically contacts the card-side housing 40 and is designed to also electrically contact the computer-side housing 20 when mounted. Thus, an electrical short circuit exists between the two housings 20 and 40, which further improves the shielding of the contact elements and thus the signal quality.

[0101] The computer-side connector element 10 and the card-side connector element 30 can, for example, have a length (approximately perpendicular to the two mounting directions M1 and M2) of approximately 85 mm, a depth (approximately parallel to the first mounting direction M1) of approximately 15 mm, and a height (approximately parallel to the second mounting direction M2) of approximately 12 mm. These dimensions are merely examples for the automotive sector and can also take on other dimensions suitable for the automotive sector depending on the application.

[0102] In the connector system 100, the computer-side and card-side differential pair contact elements 13b and 33b are arranged in spaced-apart rows, which correspond to the Figure 1 correspond to the rows of pair contact points 210 shown. The rows of differential pair contact elements 13b and 33b are spaced apart from one another in the column direction such that sufficient space remains between them for the routing channels (e.g., 230 and 232).

[0103] The Figure 3A shows in a first perspective view (oblique front view) a schematic sketch of the computer-side housing 20 of the Figure 2 shown connector system 100, while the Figure 3B the computer-side housing 20 in a second perspective view (oblique rear view). Figures 3A and 3B the contact cavities 11a-11c are shown again, which completely penetrate the computer-side housing 20 and have an approximately rectangular cross-section.

[0104] As in the Figures 3A and 3BAs shown, in particular, each of the contact cavities 11b has an approximately rectangular cross-section for rotationally fixedly receiving the differential pair insulating bodies 12b. When the computer-side connector element 10 and the card-side connector element 30 are plugged together, ie in the assembled state, the computer-side contact cavities 11a-11c and the card-side contact cavities 31a-31c together form continuous channels and / or cavities for the contact elements.

[0105] When assembled, the two housings 20 and 40 can be coupled to each other and / or electrically contacted, which improves shielding.

[0106] A first screw opening 22 is formed adjacent to the computer-side single-end contact cavity 11a on the computer-side housing 20. A second screw opening 22 is formed adjacent to the computer-side power contact cavity 11c on the computer-side housing 20.

[0107] Each screw opening 22 is designed as a (e.g., planar) enlargement of the computer-side plug-in side 14 and can protrude in a loop-like manner from the computer-side housing 20. In the illustrated embodiment, the approximately circular borders of the screw openings 22 protrude from the computer-side housing 20 approximately in the second mounting direction M2.

[0108] Also in Figure 2 The card-side housing 40 shown may have screw openings (not shown in the figures), which may be formed as zinc die-cast elements and serve to reinforce the connection of the card-side connector element 30 to the PCB card. Screw openings on the card-side housing 40 may, for example, be formed as an enlargement of the card-side plug-in side 34 (see FIG. Fig. 2 ).

[0109] Therefore, the Figure 1The printed circuit board 200 shown may have receptacles with, for example, a thread, in which screws can be screwed through the screw openings of the connector system 100 on the printed circuit board 200.

[0110] The Figure 4 shows a schematic sketch of the computer-side connector element 10 from Figure 2 . Compared to Figure 2 was in the Figure 4 For example, the computer-side housing 20 is hidden so that the computer-side insulating bodies 12a-12c and the computer-side contact elements 13a-13c are better shown. In particular, Figure 4 It is shown that the hollow insulating bodies 12a-12c surround the contact elements 13a-13c at least in some areas. In other words, the contact elements 13a-13c are arranged at least in some areas within cavities of the insulating bodies 12a-12c.

[0111] The Figure 1The printed circuit board 200 shown in sections can, in addition to the pair contact points 210 and associated routing channels, also have single-end contact points and / or power contact points for contacting the computer-side and / or card-side single-end contact elements 13a, 33a and / or power contact elements 13c, 33c. These can be routed on the printed circuit board through single-end routing channels and / or power routing channels, the position, length and further design of which essentially correspond to those of the Fig. 1 shown routing channels 230, 232.

[0112] Thus, the circuit board 200 can have a differential pair contact area in which the pair contact points 210 are arranged in rows together with the associated routing channels (e.g. 230 and 232), a single-end contact area arranged adjacent thereto in the column direction S in which the single-end contact points are arranged in rows together with the associated single-end routing channels, and on the other side of the differential pair area in the column direction S adjacent a power contact area in which the power contact points are arranged in rows together with the associated power routing channels.

[0113] Thus, the circuit board 200 can be designed to contact and / or route all contact elements 13a-c, 33a-c of the card-side and / or computer-side connector element 10, 30.

[0114] The Figure 5shows the layout of a printed circuit board 200 for contacting the computer-side connector element 10 of the connection system 100.

[0115] Here, in a central differential pair contact area 260, the pair contact points 210 are arranged in twelve rows of four individual pair contact points 210 each. For example, only a single pair contact point 210 is identified with a reference symbol. Between the individual rows of pair contact points 210, the routing channels with the conductor tracks 240 (see FIG. Fig. 1 ) arranged in Figure 5 are not shown.

[0116] Adjacent to the central differential pair contact region 260 in the column direction S, single-end contact points 270 are arranged in eight rows of seven individual single-end contact points 270 each in a single-end contact region 261 (shown on the right). For example, only a single single-end contact point 270 is identified by a reference symbol.

[0117] Single-end routing channels can be arranged between the individual rows of single-end contact points 270, which in Figure 5 are not shown.

[0118] In a power contact area 262 (shown on the left) adjacent to the central differential pair contact area 260, opposite the column direction S, power contact points 280 are arranged in four rows of five individual power contact points 280 each. For example, only a single power contact point 280 is identified with a reference symbol.

[0119] Power routing channels can be arranged between the individual rows of power contact points 280, which in Figure 5 are not shown.

[0120] The rows of pair contact pads 210, single-end contact pads 270 and power contact pads 280 can all be aligned in the row direction R.

[0121] Figure 5 further shows a dimension of the illustrated embodiment, including a spacing between the individual rows of contact points. The routing channels can be arranged at this row spacing.

[0122] The printed circuit board 200 can be approximately 1.20 mm + / - 0.10 mm thick.

[0123] The individual contact points of the pair contact points 210, the single-end contact points 270 and / or the power contact points 280 may have holes with a diameter of about 0.30 mm to about 0.50 mm, preferably about 0.40 mm. List of reference symbols
