Description

[0001] SPE connector for a plug connection

[0002] The invention relates to an SPE connector for an electrical SPE connector, according to the preamble of claim 1.

[0003] SPE connectors of this type are used to connect electrical contacts on the mating faces of corresponding, mating SPE connectors and SPE mating connectors, to the other faces of which an SPE cable (SPE = Single Pair Ethernet) or electronics, for example in the area of ​​a printed circuit board, can be connected. The two SPE connectors are usually locked together using suitable locking mechanisms. For the state of the art, reference is made to WO 2021 / 190899 A.

[0004] An SPE cable has two conductors, usually twisted together, embedded in conductor insulation. These conductors and their insulation are each located within a cable shield. The cable may also have a cable jacket surrounding the cable shield.

[0005] If the two plug contact sections are to be arranged relatively close to each other in the plug face, it is structurally difficult to maintain the necessary air and creepage distances in the area of ​​the contact elements.

[0006] The solution to this problem is the purpose of the invention.

[0007] The invention solves this problem through the subject matter of claim 1.

[0008] Advantageous embodiments of the invention can be found in the dependent claims.

[0009] According to claim 1, an SPE connector for an electrical connection is provided, comprising at least the following: exactly two contact elements made from a flat strip material such as a metal sheet blank, which are inserted into a plastic contact carrier, which in turn is inserted into a shield housing, wherein the contact elements each have a plug-in contact section, a busbar section extending thereon in a plug-in direction, and at least one terminal contact. This arrangement is advantageously characterized in that the two busbar sections are aligned parallel to each other, at least partially or over their entire extent, so that they have main outer surfaces parallel to each other.This results in a compact arrangement with contact elements offering high current-carrying capacity, which can nevertheless be positioned relatively close to each other within the contact carrier, while also ensuring excellent data transmission characteristics of the SPE connector in the area of ​​these contact elements. Even increased requirements for clearance and creepage distances can be easily met. This also allows for surprisingly large clearance and creepage distances, even in the area of ​​the two contact elements.

[0010] In this document, a metal sheet blank also refers to a section of metal strip cut to length from a flat strip. Contact elements made from such material, particularly those manufactured in one piece, can be produced cost-effectively, with further cost advantages possible if the contact elements are designed as identical parts.

[0011] According to a preferred optional embodiment, the shield housing can be inserted into a connector outer housing, which preferably consists of an insulating plastic and can thus form insulation to the shielding plate or shield housing, which can also facilitate handling.

[0012] In a further preferred optional embodiment, the plug-in contact sections of the contact elements can each be designed as socket contacts, each having two contact legs that are preferably oriented substantially perpendicular to the respective busbar sections. Alternatively, the plug-in contacts could also be designed as pin contacts. In a further preferred optional embodiment, the connection contacts of the contact elements can each be designed as a solder pin, which allows them to be arranged on a printed circuit board. Other solder contacts can also be provided instead of solder pins. In this way, a design as a printed circuit board connector can be achieved particularly well.

[0013] In a further preferred optional embodiment, the connection contacts of the contact elements, designed as respective solder pins, can be oriented perpendicular to the insertion direction of the plug contacts, thus making it particularly advantageous to implement a printed circuit board connector using SPE technology. However, other orientations of the connection contacts, especially the solder pins, are also possible.

[0014] In a further optional, expedient, and advantageous embodiment, the contact carrier is made of a plastic and has a base housing in which two contact chambers are formed. These chambers extend through the contact carrier in the X direction and are each designed to receive and hold one of the two contact elements. This is advantageous for creating a well-insulating contact carrier in which the contact elements can be securely accommodated and held.

[0015] According to a further preferred optional embodiment, the two contact elements can be designed differently, in particular as mirror-symmetrical parts, rather than as identical parts. While the latter is somewhat less cost-effective, it allows for at least comparable electrical properties to be achieved.

[0016] According to a further preferred optional embodiment, it can be provided that one or more locking elements and / or a stop edge are provided on the contact elements and one or more counter-locking means and / or a stop wall are provided on the contact carrier in order to fix the respective contact element in the contact carrier.

[0017] Advantageous measures for achieving good shielding and good high-frequency characteristics of the SPE connector arise in particular, both individually and in combination, from the claims relating to the further development of the shield housing. These also include, among other things, further measures for the mechanical optimization of the connector.

[0018] According to a preferred optional embodiment, the shield housing may have a preferably circumferentially closed collar section in the insertion direction X, which surrounds the contact carrier up to the area of ​​the insertion face, wherein the two contact elements are arranged approximately centrally in the shield housing, so that the two contact elements are approximately equidistant from corresponding walls of the shield housing. According to a further preferred optional embodiment, the shield housing may also have at least one first fastening element which is attached to at least one counter-fastening element of the contact carrier, so that these elements are advantageously connected to one another.

[0019] In one possible variant, the fastening means of the shield housing can advantageously and simply be designed as a first locking element of the shield housing, for example as a locking hook, which is connected to a counter-locking element, preferably a locking edge of the contact carrier, and / or it can be provided that the fastening means of the shield housing is designed as a first material closure element of the shield housing, which interacts with a counter-closing element of the contact carrier, e.g. in the manner of an adhesive bond.

[0020] The fastening element and the counter-fastening element can also be designed differently and include one or more corresponding embossed areas that interact.

[0021] In a particularly advantageous and easy-to-handle design, the locking hook or locking protrusion can be punched and bent or embossed from the sheet metal of the shield housing and fixed to the counter-locking element of the contact carrier. In this way, the shield housing and contact carrier elements can be easily and securely fastened together.

[0022] According to a further preferred optional embodiment, the shield housing may also have one or more further fastening means, in particular locking means or embossing means, preferably one or more further locking hooks, which are also punched and bent out of the sheet metal of the shield housing, and which are fixed to corresponding counter-fastening means, in particular anti-rust means of the connector housing, such as at one or more locking openings or in a groove.

[0023] The shield housing and connector housing can also be easily and securely attached to each other in this way. Other connection types are also optional or alternatively possible.

[0024] According to a further preferred optional embodiment, the contact carrier may have ribs extending parallel to the connection contacts, with the shield housing having a shield housing rib on the outside parallel to these, on which one or more solder pins may be formed that can be soldered to the circuit board of the assembly to be connected or connected, wherein preferably the solder pins of the shield housing are arranged in a direction perpendicular to the plug-in direction approximately in the middle between the connection contacts.

[0025] And according to a further preferred optional embodiment, a wall section can be formed on the shield housing, preferably extending the collar section against the plug-in direction, which can be folded down from the X / Y plane into a Y / Z plane and which then at least partially covers and shields the two contact elements in the area of ​​the ends of the busbar sections against the plug-in direction. The folded-down wall section and the contact carrier can, for example, also be connected to each other by one or more joining connections.

[0026] According to a further preferred optional embodiment, lateral fixing lugs of the contact carrier project outwards from the base housing into a respective gap in the shield housing between the folded-down wall section and the end of the collar section facing away from the mating face. The shield housing is secured to the contact carrier by these lateral fixing lugs. Furthermore, according to another preferred optional embodiment, fixing lugs are formed on the collar section of the shield housing that engage under the base housing of the contact carrier, in particular such that a circumferential connection and, if necessary, an additional contact point between conductive elements of the shield housing is created. This further optimizes both the shielding properties and the mechanical properties of the connector.

[0027] The invention is described in more detail below with reference to the drawings and exemplary embodiments. These show particularly advantageous embodiments of the invention, to which the invention and the scope of protection of the claims are not limited. Rather, alternatives and equivalents of the illustrated exemplary embodiments can also be realized within the scope of the invention and the scope of protection. The drawings show:

[0037] Fig. 12 shows a perspective view of another variant of a pre-assembled unit of a fourth shield housing with a contact carrier with two contact elements inserted therein, for a housing of an SPE connector, which can otherwise be designed according to the type of Fig. 1; and

[0038] Fig. 13 shows a perspective view of an arrangement consisting of a housing and a pre-assembled unit consisting of a fifth shield housing with a contact carrier containing two contact elements for a further SPE connector.

[0039] Figures 3 and 4 show a fully assembled SPE connector 1 for transmitting electrical power and data / signals, which has a mating face 10. A Cartesian coordinate system X, Y, Z is used for orientation.

[0040] Figures 1 and 2 show the SPE connector 1 in exploded view.

[0041] The SPE connector 1, or rather its mating face 10, is designed for mating with a corresponding SPE connector (not shown) that has a mating face corresponding to that of the first SPE connector and to which, in particular, an SPE cable can be connected. The two SPE connectors can be mated together at their mating faces, thus forming an SPE connection. In this way, for example, an SPE cable with an electrical assembly can be connected to a printed circuit board. The mating direction against which the illustrated SPE connector is contacted when the second SPE connector (not shown) is moved is the X direction in the coordinate system.

[0042] As can be indirectly seen from the interplay of Figures 1 to 10, the SPE connector 1 can be designed as a printed circuit board connector that can be mounted onto an electrical assembly, in particular one with a printed circuit board (not shown here). In this case, the connector housing 6 and / or the shield housing 5 can be (partially) open towards the printed circuit board (here against the Z-direction) perpendicular to the insertion direction X, since the electrical assembly, in particular its printed circuit board, can form a closure on this side (see also Figures 2, 4 and 7).

[0043] The SPE connector 1 has two contact elements 2, 3. These contact elements 2, 3 are inserted into a contact carrier 4, which in turn is inserted into a shield housing 5 (preferably made of a shielding plate). This shield housing 5 is finally inserted into a connector outer housing 6 – hereinafter referred to synonymously as connector housing 6.

[0044] In a preferred embodiment, the two contact elements 2, 3 are constructed identically. This is readily apparent from the top view of the two contact elements 2, 3 in Fig. 9 in combination with the side view of the contact element 2, 3 in Fig. 10. The respective contact element 2, 3 is preferably designed as a stamped and bent part, which is cut from a sheet metal – a highly electrically conductive flat strip material such as a copper alloy – and then formed into the shape shown in Figs. 9 and 10.

[0045] The respective contact element 2 (or 3) has a plug-in contact section that forms part of the plug-in face of the SPE connector. These plug-in contact sections can preferably be designed as socket contact sections 21, 31.

[0046] To the respective plug contact section, here to the respective socket contact section 21 , 31 , a respective busbar section 22, 32 is connected against the plugging direction, on which one or more connection contacts 23, 33 may be formed.

[0047] The plug contact sections, here the respective socket contact sections 21 , 31, form part of the plug face 10 of the SPE connector and are designed to be plugged together with corresponding plug contacts of the second SPE connector, which may be designed as pin or knife contacts, for example (not shown here).

[0048] The busbar sections 22, 32 (see in particular Fig. 9 and 10) are essentially designed as flat, planar sections that are aligned parallel to each other (in or parallel to the X / Z plane), so that two of their respective main outer surfaces are parallel to each other.

[0049] The socket contact sections 21, 31 of the contact elements 2, 3 are punched out of the metallic flat strip material and protrude here relative to the busbar sections 22, 32 from the main extension plane of the flat strip material by 90°, so that their legs are essentially opposite each other in two planes aligned parallel to the X / Y plane.

[0050] The legs of the socket contact sections 21, 31 do not extend exactly in the X / Y plane, but rather run from the busbar sections 22, 32 preferably initially towards each other up to a contact area 211, 311 and then widen in such a way that a centering aid for the mating contact of the mating connector to be inserted is created in a manner known per se (see Fig. 10).

[0051] The one or more respective connection contacts 23, 33 of the contact elements 2, 3 can be designed as solder contacts, for example as solder pins that can be used for soldering to a printed circuit board (not shown here). These solder pins can, for example, protrude from the busbar sections 21, 31 essentially at right angles to the insertion direction X, which is advantageous if the SPE connector is to be used as a printed circuit board connector that can be soldered onto a printed circuit board (not shown here) through which it can pass ("90° connection"). However, the solder pins can also extend in a different direction, for example parallel to or against the insertion direction X. The connection contact sections 23, 33 can also be designed differently than shown in the figures, if necessary – in other connection situations. The two contact elements 2, 3 can preferably be designed as identical parts.

[0052] The two contact elements 2, 3 each have a total extent X1 in the direction X.

[0053] Since the two contact elements 2, 3 are preferably arranged over most of their total extension X2 in the X-direction such that they are aligned parallel to each other parallel to or parallel in the X- / Z-plane, a very large or even the largest possible distance between the two contact elements 2, 3 is easily achieved, so that on the one hand a relatively large cross-section can be realized and yet high requirements for air and creepage distances can still be met very well (see in particular Fig. 9 and compare Fig. 1 and 2).

[0054] This is particularly advantageous when the distance between the two contact elements 2, 3 perpendicular to the X-direction in the Y-direction is very small.

[0055] These two contact elements are inserted into the contact carrier 4 from the rear in the X direction. The contact carrier 4 has a base housing 41 in which two (preferably at least partially, e.g., slot-shaped) contact chambers 411, 412 are formed, which extend through the contact carrier 4 in the X direction and which are each designed to receive and hold one of the two contact elements 2, 3.

[0056] The base housing 41 of the contact carrier 4 can be made of an electrically insulating plastic. The contact chambers 411, 412 extend to the plug-in face and are open in the plug-in direction X, so that the two socket contact sections 21, 31 can be contacted against the plug-in direction X.

[0057] Preferably extending from the plug-in face 10, a partition 43 (see Figs. 3 and 4) extends between the contact elements 2, 3, preferably reaching to or almost reaching the ends of the contact elements 2, 3 facing away from the socket contacts 21, 31. In the area of ​​the busbar sections 22, 32, one or more locking elements can be provided, here a locking hook 24, 34, each designed and configured for locking against an anti-corrosion element – ​​here a (not visible) locking opening in the contact carrier 4. In this way, the contact elements 2, 3 can be easily and securely inserted into the contact chambers 411, 412 that extend through the contact carrier 4 in the X direction, where they are held securely.The two contact elements 2, 3 can have a stop edge (narrow side) 25, 35 at the rear end in the transition to the connection contacts 23, 33, which, when inserted into the contact carrier 4, abuts a corresponding stop wall of the housing 41, contributing to a defined seating of the contact element 2, 3 in the contact carrier 4.

[0058] The base housing 41 of the contact carrier 4 can have a web 44, 45 in the area of ​​the connection contacts 23, 33, preferably running parallel to these, in order to protect the connection contacts 23, 33 against bending and to provide a contact surface for the shield housing webs (53, 54) of the shield housing (5) (see Fig. 2).

[0059] The shield housing 5 is made of a highly conductive sheet metal. It is preferably designed as a stamped / bent part, like the contact elements 2 and 3. The shield housing 5 is designed such that it surrounds or encompasses the contact carrier 4 over a large portion of its surface. In the insertion direction X, the shield housing 5 can have a collar section 51 that extends around the contact carrier 4 up to the area of ​​the mating face 10. In this area, the shield housing 5 is open in the insertion direction X, allowing contact with the contact elements 2 and 3. In this area, the shield housing 5 can also be contacted by a corresponding shielding element of the mating connector (not shown here).

[0060] The shield housing 5 is preferably manufactured from a highly electrically conductive metal sheet using a stamping / bending process, in particular from a metal strip material. It is preferably a single piece, which is simple, beneficial for the shielding properties, and cost-effective. It may include a fastening means for attachment to a mating fastening means of the contact carrier 54 (Fig.

[0061] 2).

[0062] The fastening element can include a first locking element, here a locking hook 521, which can be punched out of the sheet metal of the shield housing 5 and bent outwards – here inwards – and which is designed to engage a counter-locking element, here a locking edge 46 of the contact carrier 54 (Figs. 1 and 2, 11a). Alternatively, the fastening element and the counter-fastening element can have corresponding, cooperating embossings 524 or the like, or adhesive areas 47 (e.g., adhesive dots) (Figs. 11b) and c)). In this way, the shield housing and contact carrier elements can each be easily and securely fastened to one another.The shield housing 5 may further comprise one or more additional fastening means, such as locking devices, in this case additional locking hooks 522, 523, which may also be punched and bent outwards from the sheet metal of the shield housing 5 – here outwards – and which may be designed to fasten to corresponding counter-fastening devices, in particular anti-rust devices, of the connector housing 6, e.g., at one or more locking openings 61. Additionally or alternatively, other fastening devices and counter-fastening devices may also be provided here, for example, embossed and / or harpoon lugs 525 on the shield housing 5, which can be pressed into the connector housing 6 (Fig. 13), e.g., in the area of ​​a respective groove 62 inside the connector housing 6. The window 61 may then be omitted.

[0063] It can then be provided that a shield housing rib 53, 54 extends parallel to the webs 44, 45 of the contact carrier 4, on which one or more solder pins 531, 532, 541, 542 can be formed, which can be soldered to the circuit board of the assembly to be connected or already connected. An advantageous wall section 511 can be provided on the shield housing 5 in extension of the collar section 51 against the insertion direction X, which can be folded down from the X / Y plane into a Y / Z plane perpendicular to the insertion direction X and which then also shields the two contact elements 2, 3 against the insertion direction X, here in the area of ​​the ends of the busbar sections 22, 32 (see Fig.

[0064] 4) This rear “closure” of the shielding plate or shielding housing 5 is advantageously simply bent downwards and rusted and / or clamped and / or pressed only after the contact carrier 4 has been inserted into the shielding housing 5; in this embodiment, the shielding plate can preferably be pressed into a groove in the housing.

[0065] It can be provided that, in a respective gap 55 of the shield housing 5 between the folded-down wall section 511 and the end of the collar section 51 facing away from the plug-in face 10, lateral fixing lugs 441, 451 of the contact carrier 4 project outwards from the base housing 41, by which the shield housing 5 is additionally fixed to the contact carrier 4. Reversals of this principle are also possible. The shield housing 5 can, for example, have a window 526 at its rear end – in the folded-down wall section 511 – into which a fixing lug 461 of the contact carrier 4 can engage (see Fig. 12) to achieve a fixation, for example, a joining fixation. This fixing can be further optimized by forming fixing lugs 512, 513 on the collar section 51, which further optimize the seating of the shield housing 5 on the base housing 41 of the contact carrier 4 by engaging underneath the base housing 41.They can come into contact, resulting in a circumferential connection and, if necessary, an additional contact point of conductive elements of the shield housing 5 "among themselves", which further optimizes the shielding properties of the shield housing 5.

[0066] Fig. 7 illustrates that the collar section 51, particularly towards the plug-in face 10, can also be partially circumferentially closed by forming the preferably one-piece shielding sheet into a circumferentially closed element using a stamping / bending process, while remaining open towards the circuit board in a rear area. In the illustration, the contact carrier 4 is omitted to demonstrate the uniform distance between the contact elements 2, 3 and the shielding housing 5. This is advantageous for good high-frequency characteristics.

[0067] The shielding plate or shielding housing 5 with the contact carrier 4 pre-mounted therein with the two contact elements 2, 3 pre-mounted therein can be inserted into the connector housing 6 as a pre-assembled unit and secured there.

[0068] The connector housing 6 can also be made of an electrically insulating plastic.

[0069] The contact elements 2 and 3 are advantageously designed as identical parts. This is advantageously cost-effective but not essential.

[0070] The contact elements 2, 3, which can be designed as identical parts, are then arranged in the contact carrier 4 in the same direction – with respect to a central plane ME (an X / Z plane), see Fig. 10 – between the two busbar sections 22, 32. Their locking hooks 24, 34 then project in the same direction from the busbar sections 22, 32. And the socket contacts 21, 33 are then bent in the same directions from the respective sheet metal blank from which the respective contact element was manufactured.

[0071] Alternatively, the socket contacts 23, 33 can also be designed symmetrically about a central plane ME (not shown here). In this case, two different contact elements 2, 3 must be manufactured, and the locking hooks 24, 34 will then, for example, not protrude in the same direction from the busbar sections 22, 32, and the socket contacts 23, 33 may not be bent in the same direction from the respective sheet metal blank from which the respective contact element was manufactured. However, this results in comparably good mechanical and electrical properties (this solution is not shown here).

[0072] The two contact elements 2, 3 are each surrounded by the shielding plate or housing 5, respectively, over most of their extent, essentially in the center, such that the lateral distances of the contacts 2, 3 to the housing 5 are essentially the same over most of their extent. This is beneficial for the high-frequency characteristics of the SPE connector 1, as it reduces interference during signal / data transmission. The advantageous arrangement, particularly of the busbar sections 22, 32, results in a very large contact surface area, so that even with the use of only a thin strip of metal (Y-direction), a large cross-section is achieved, leading to high current-carrying capacity. This is advantageous, for example, for "Power over data line" applications, such as supplying sufficient power to a camera.

[0073] The spacing of the solder pads or connection contacts 23, 33 of the contact elements 2, 3 corresponds exactly or approximately to the spacing of the two busbar sections 22, 32, which is also very advantageous. The solder pads or connection contacts 23, 33 of the contact elements 2, 3 are located on the circuit board approximately centrally between solder pins 531, 532, 541, 542 of the shield housing 5, which also contributes to symmetry for advantageous high-frequency characteristics.

[0074] It should also be noted that, to ensure extended functionalities, one or more LEDs may be formed on the SPE connector 1; their solder pins may be led straight out of the contact carrier 4 to the rear and then bent towards the circuit board (not shown here).

[0075] The arrangement of the connection contacts 23, 33 of the contact elements 2, 3 and the solder pins 531, 532, 541, 542 of the shield housing 5 is such that the conductor traces of the printed circuit board, which are to be connected to the connection contacts 23, 33, can be routed at equal intervals without sharp bends to the rear, especially against the insertion direction X (which optimizes the impedance characteristics).
