Description

Technical Field

[0001] The invention relates to a plug connector component according to the preamble of claim 1 , and to a plug connector system. Background Art

[0002] Such plug connector parts usually include a plurality of contact elements for contacting contact elements of another plug connector part in a pluggable manner. These plug connector parts can be plugged with another plug connector part of the plug connector system along a plugging direction.

[0003] The contact elements of the plug connector part can be arranged in at least one contact element row, for example, along a row direction running transversely to the plugging direction, and can have a base body extending in a main extension plane arranged perpendicular to the row direction.

[0004] Such plug connector components are often used in so-called board-to-board plug connector systems. To improve signal or data transmission, it may be necessary to modify the impedance characteristics of the plug connector component. However, at the same time, the power transmission performance of the plug connector component should be minimized. Summary of the Invention

[0005] The object of the present invention is to provide a plug connector component which allows for improved signal and power transmission.

[0006] This object is achieved by the subject matter having the features of claim 1 .

[0007] Accordingly, the plug connector part has at least two contact elements, the base bodies of which are designed differently from one another.

[0008] At least two contact elements are provided in a plug connector part for pluggably contacting contact elements of another plug connector part, and these contact elements are arranged in at least one contact element row along an arrangement direction. Thus, these contact elements form (at least one) contact element row, along which the contact elements are arranged one above the other.

[0009] In this case, the plug connector part can have one or more contact element rows, each of which comprises at least two contact elements.

[0010] In particular, the plug connector part can realize together with another plug connector part a so-called board-to-board plug connector, via which two circuit boards can be electrically connected to one another by plugging the corresponding plug connector parts together.

[0011] The plug connector component has at least two contact elements whose base bodies are designed differently from one another. In particular, each contact element row of the plug connector component can have at least two contact elements having different base bodies. The arrangement of different contact elements in the contact element rows makes it possible, on the one hand, to provide one or more contact elements that are optimized for signal transmission and are shaped, for example, for impedance matching to enable reflection-free signal transmission, and, on the other hand, to provide contact elements that are optimized for energy transmission and, for example, have a conductor cross-section that allows even high currents to be transmitted.

[0012] Contact elements optimized for signal transmission may also be referred to as signal contacts. In contrast, contact elements optimized for energy transmission may be referred to as power contacts or power contacts, for example.

[0013] In one embodiment, the plug connector part has at least two contact elements, the base bodies of which have mutually different widths in a transverse direction running perpendicularly to the plug-in direction and perpendicularly to the row direction.

[0014] In one embodiment, the base bodies of at least two contact elements each have a first end region, a second end region, and a main region. The main region can be arranged between the first and second end regions. For example, each contact element can be connected to a circuit board at the first end region. At the second end region of the base body, the contact element can have at least one contact strap for pluggable contact with a corresponding contact element of another plug connector component.

[0015] A plug connector part can be plugged into another plug connector part, for example, by moving the two plug connector parts toward each other, or by moving only one plug connector part toward the other plug connector part. Thus, for each plug connector part, the plugging direction can be defined as the direction from the first end region to the second end region.

[0016] The contact strap can be designed as a contact pin or a bent end of a contact element, for example. The contact strap can be pluggably engaged with a mating contact strap of a mating contact element.

[0017] The at least two contact elements of the plug connector component preferably each have two contact straps. The first contact strap can, for example, extend in the main extension plane of the base body, for example, in the plug-in direction, away from the base body. In particular, the first contact strap can extend completely in the main extension plane of the base body. The second contact strap can also extend away from the base body in the plug-in direction. For example, the second contact strap is arranged on the base body in an offset manner relative to the first contact strap, in a direction extending perpendicularly to the plug-in direction and perpendicularly to the arrangement direction. For example, the second contact strap can be connected to the base body via a connecting section, in the region of which a bend is formed, so that the second contact strap partially extends out of the main extension plane of the base body in the arrangement direction.

[0018] For example, a soldering area (e.g., a connecting piece or soldering plate) can be arranged at the first end region of the base body of the contact element for connection to a circuit board. The connecting piece or soldering plate can, for example, protrude perpendicularly to the main extension plane of the base body and away from the base body at the first end region. The connecting piece can, for example, be connected to a circuit board and connected to a conductive track on the circuit board. For example, multiple or all contact elements of a plug connector component can be connected together to a single circuit board. To this end, the circuit board can have connection points, to which the contact elements can be soldered, for example, so that the contact elements are mechanically fixed to the circuit board and electrically contact the circuit board.

[0019] The contact straps and the connecting pieces or welding plates are preferably formed integrally with the base body of the respective contact element. The contact element can be made, for example, as a stamped and bent part, for example, from a metal sheet.

[0020] In one embodiment, the plug connector part has at least one contact element of a first type and at least one contact element of a second type, wherein the at least one contact element of the first type and the at least one contact element of the second type are designed differently from one another in the main region of their respective base bodies.

[0021] In one embodiment, at least one contact element of the first type and at least one contact element of the second type are designed to be identical to one another at the respective first end region and / or the respective second end region of their base bodies. Thus, it is possible for the first and second types of contact elements to differ from one another only in the main region.

[0022] In one embodiment, the base body of the at least one second type contact element has a geometric structure for impedance matching in the main region of the base body. In this way, the at least one second type contact element can be implemented as a contact element optimized for signal transmission, for example, and can be referred to as a signal contact.

[0023] In one embodiment, the geometric structure for impedance matching is designed as a cross-sectional area reduction of the base body in the main region. Alternatively, it is conceivable that the geometric structure for impedance matching is designed as a cross-sectional area expansion of the base body in the main region.

[0024] Within the scope of this description and the appended claims, the cross-sectional area of ​​the base body is, in particular, the area of ​​the base body of at least one contact element in a cross section along a cross-sectional plane extending perpendicularly to the plug-in direction and is therefore measured based on the area in the cross section (two-dimensionally determined by the width and material thickness).

[0025] Within the scope of the present description and the appended claims, the width of the base body is preferably a width taken perpendicularly to the plugging direction and perpendicularly to the arrangement direction.

[0026] In one embodiment, the impedance matching geometry has at least one tapering region in which the width or cross-section of the base body of at least one second type of contact element is tapered. For example, the impedance matching geometry can have a first tapering region, which is arranged on one side of the first end region and tapers in the plug-in direction. The impedance matching geometry can also have, for example, a second tapering region, which is arranged on one side of the second end region and tapers opposite the plug-in direction. The impedance matching geometry can, for example, have two tapering regions, which can be arranged mirror-imaged relative to one another, in particular with respect to a mirror plane arranged perpendicular to the plug-in direction. The path of the impedance matching geometry is preferably continuous in the at least one tapering region.

[0027] In one embodiment, the geometric structure for impedance matching has a central region arranged between two constricted regions. The width and / or the cross-sectional area of ​​the base body is preferably constant in the central region.

[0028] In one embodiment, the impedance matching geometry extends at least partially uniformly along the direction of extension of the main region between the first end region and the second end region. The term "uniformly along the direction of extension" is understood to mean a direction in which the lateral delimiting edges of the main region each extend (approximately) straight or curved. For example, the width can vary continuously, resulting in a geometry that continuously widens or narrows (along the direction of extension). Alternatively, the width can also remain constant at least partially and thus not vary along the direction of extension, resulting in a geometry with a constant width.

[0029] Advantageously, the uniform course of the geometric structure allows for simple and precise impedance matching.

[0030] In one embodiment, the geometric structure for impedance matching is arranged on at least one side section of the main region of the base body of at least one second-type contact element. For example, sheet-shaped material sections can be arranged on the side section to increase the cross-sectional area, or corresponding sheet-shaped cutouts can be arranged in the side section to reduce the cross-sectional area depending on the desired impedance matching.

[0031] For example, the disc-shaped section / cutout can be formed integrally with the material of the at least one second type of contact element, or can already be taken into account during the production of the at least one second type of contact element. Alternatively, the disc-shaped section / cutout can also be added / removed after the production of the at least one second type of contact element.

[0032] In one embodiment, the geometric structures for impedance matching are arranged on opposite side sections of the main region of the base body of at least one second type contact element. For example, two geometric structures for impedance matching are arranged in mirror image on the side sections of the main region of the base body.

[0033] Advantageously, this embodiment allows for better handling of mechanical loads on the at least one contact element of the second type and, at the same time, impedance matching.

[0034] In one example, the minimum width of the main region having the geometric structure for impedance matching is in the range of 0.6 mm to 1 mm, in particular 0.8 mm.

[0035] For example, a plug connector with this second type of contact element can have a pitch of 0.8 mm. In one example, with a minimum width of 1 mm, the impedance drops to approximately 85 Ω. Advantageously, impedance matching can be achieved not only by varying the cross-sectional area of ​​the main region (which has a geometry for impedance matching) but also by varying the length of the main region. By varying the length, the main regions of the base body of the second type of contact element can have a uniform shape, thus avoiding larger interference areas.

[0036] In one configuration, the width-to-length ratio of the main region of the base body of at least one second type of contact element is in the range of 1:1.5 to 1:2.5, in particular 1:2.

[0037] Surprisingly, it has been found that particularly good impedance matching results can be achieved by setting the width-to-length ratio of the main region of the base body of at least one second-type contact element to 1:2. Furthermore, it has been found that the width-to-length ratio of the main region of the base body of at least one second-type contact element can be easily scaled over a wide range for different applications. Thus, advantageously, by designing at least one second-type contact element such that the main region of its base body has a width-to-length ratio in the range of 1:1.5 to 1:2.5, in particular a width-to-length ratio of 1:2, a standardized second-type contact element can be achieved that enables simple impedance matching.

[0038] In one embodiment, the base body of at least one first-type contact element and the base body of at least one second-type contact element each have a cross-sectional area in the main region, wherein the cross-sectional area of ​​the base body of the at least one second-type contact element is smaller than the cross-sectional area of ​​the base body of the at least one first-type contact element. Thus, compared to the at least one second-type contact element, the first-type contact element has a larger cross-sectional area (in a cross section along a cross-sectional plane perpendicular to the plug-in direction), at least in an axial position, in particular in the main region, than the cross-sectional area of ​​the second-type contact element. In this way, the first-type contact element can be optimized for energy transmission, while the second-type contact element can be optimized for signal transmission.

[0039] In a top view along the arrangement direction, the main region of the base body of the at least one first type contact element is preferably rectangular. Therefore, the width and cross-sectional area of ​​the base body of the at least one first type contact element are preferably constant in the main region between the first end region and the second end region.

[0040] In one embodiment, at least one contact element row has a plurality of contact elements. For example, at least one contact element row has 5, 10, 15 or more than 15 contact elements.

[0041] In one embodiment, the plug connector part has a plurality of, for example two, rows of contact elements, wherein the rows of contact elements are arranged parallel to the row direction and / or parallel to one another.

[0042] In one embodiment, the contact straps of the contact elements of the first contact element row and the contact straps of the contact elements of the second contact element row are arranged mirror-image-like relative to one another with respect to a mirror plane that runs parallel to the plug-in direction and parallel to the arrangement direction.

[0043] In one embodiment, the contact element is a hermaphroditic contact element. Such hermaphroditic contact elements are known, for example, from WO 2019 / 291768 A1. Therefore, reference is made to the patent application published as WO 2019 / 291768 A1 in this regard, the content of which is hereby incorporated into the present application.

[0044] Plug connector parts with hermaphroditic contact elements can be plugged into one another to establish electrical contact between the contact elements. The hermaphroditic contact elements of the plug connector parts are designed to be locally identical, so that one plug connector part is not attached to a socket contact and the other to a plug contact, as is customary. Instead, the hermaphroditic contact elements have both socket and plug properties.

[0045] Preferably, the contact straps of the contact elements of the individual contact element rows are oriented identically to one another or are arranged identically to one another.

[0046] In one embodiment, each contact element row of the plug connector component has at least two contact elements, the base bodies of which are designed differently from one another. In particular, it is conceivable for each contact element row to have contact elements of a first type and contact elements of a second type. For example, each contact element row can have a plurality of contact elements of the first type and a plurality of contact elements of the second type.

[0047] In one embodiment, a plurality of contact elements of the plug connector component are electrically connected in parallel to one another. For example, a plurality of first-type contact elements can be electrically connected in parallel to one another. In addition, a plurality of second-type contact elements can also be electrically connected in parallel to one another.

[0048] The invention further relates to a plug connector system comprising a first plug connector part according to the invention and a second plug connector part according to the invention. The plug connector system may be, for example, a board-to-board plug connector system.

[0049] In the connected or plugged state of the plug connector system, the contact elements of the first plug connector part can be plugged into contact elements of the second plug connector part, wherein the opposing and plugged contact elements of the two plug connector parts can be of the same type.

[0050] For example, the contact elements of the first plug connector part (these are contact elements of the first type) can be plugged with the contact elements of the second plug connector part (these are contact elements of the first type). In addition, for example, the contact elements of the first plug connector part (these are contact elements of the second type) can be plugged with the contact elements of the second plug connector part (these are contact elements of the second type).

[0051] It is conceivable that the base body of the contact element of the first plug connector part has a length in the plugging direction that differs from the length of the base body of the contact element of the second plug connector part in the plugging direction. For example, the base body of the contact element of the first plug connector part can be longer in the plugging direction than the base body of the contact element of the second plug connector part.

[0067] Identical or functionally equivalent elements are provided with the same reference symbols in all figures.

[0068] Figure 1 1 shows a plug connector system 100 having a first plug connector part 102 and a second plug connector part 104. Figure 1 In the embodiment, the first plug connector part 102 and the second plug connector part 104 are not plugged into each other, so that the plug connector system 100 is Figure 1 The plug connector system 100 may be a so-called board-to-board plug connector system 106 .

[0069] Figure 2 Shows the state of connection or plug-in, according to Figure 1 A plug connector system 100 is provided, wherein a first plug connector part 102 and a second plug connector part 104 are plugged into one another along a plug-in direction 108 .

[0070] The plug connector parts 102, 104 each include a plurality of contact elements 110, which are each used to contact the contact elements 110 of the other plug connector part 102, 104 in a pluggable manner, so that the contact elements 110 of the first plug connector part 102 can be plugged into the contact elements 110 of the second plug connector part 104 along the plugging direction 108. The plug connector parts 102, 104 also each include a housing, which is not shown in the figures. For a clearer overview, Figure 1 and Figure 2 Only individual contact elements of these contact elements 110 are marked with reference numerals. The plug connector parts 102, 104 can be plugged into each other, for example, by moving the two plug connector parts 102, 104 toward each other. Figures 1 to 6 Marked with double arrows.

[0071] exist Figure 1 and Figure 2 The contact elements 110 of the plug connector parts 102, 104 shown in FIG are arranged in two contact element rows 114 along an arrangement direction 112 running transversely to the plug-in direction 108. The two contact element rows 114 are arranged parallel to the arrangement direction 112 and parallel to each other and each have 19 contact elements 110.

[0072] The contact elements 110 have a substantially planar extension. The contact elements 110 each have a base body 116 (see Figures 3 to 6 ), the base body extends in a main extension plane which is arranged perpendicular to the arrangement direction 112. In the exemplary embodiment shown in the figures, the contact elements 110 are produced as bent stamped parts from sheet metal.

[0073] The base body 116 of the contact element 110 of the plug connector parts 102, 104 respectively has a first end region 118, a second end region 120 and a main region 122. The second end region 120 and the first end region 118 are opposite, and the main region 122 is arranged between the first end region 118 and the second end region 120.

[0074] At the first end region 118, the contact element 110 is connected or can be connected to a circuit board (not shown). To this end, connecting lugs 124 are arranged on the first end region 118 of the base body 116 of the contact element 110 for connection to the circuit board. These connecting lugs 124 extend perpendicularly to the main extension plane of the base body 116 and away from it. These connecting lugs 124 can, for example, be connected to conductive tracks on the circuit board. To this end, the circuit board can have connecting points to which the contact element 110 is soldered, for example, so that the contact element 110 is mechanically fixed to the circuit board and electrically contacts the circuit board.

[0075] The contact elements 110 of the plug connector parts 102, 104 each have two contact straps 126 at the second end region 120 (see Figure 1 、 2 , 7 and Figure 8 ). The first contact strap 126A projects in the main extension plane of the base body 116 in the plug-in direction 108 away from the base body 116 and extends completely in the main extension plane of the base body 116. The second contact strap 126B also projects in the plug-in direction 108 away from the base body 116. The second contact strap 126B is arranged on the base body 116 in an offset manner relative to the first contact strap 126A, in a direction running perpendicular to the plug-in direction 108 and perpendicular to the arrangement direction 112. The second contact strap 126B is connected to the base body 116 of the contact element 110 via a connecting section 128, in the region of which a bend is formed, so that the second contact strap 126B partially projects out of the main extension plane of the base body 116 in the arrangement direction 112.

[0076] The contact element 110 is a hermaphroditic contact element here, so that in principle two contact elements 110 embodied identically at the second end regions 120 of their base bodies 116 can be plugged into one another in order to establish an electrical contact between the contact elements 110 .

[0077] The contact straps 126 of the contact elements 110 of the first contact element row 114A and the contact straps 126 of the contact elements 110 of the second contact element row 114B are arranged in mirror image with respect to a mirror plane running parallel to the plug-in direction 108 and parallel to the arrangement direction 112. The contact straps 126 of the contact elements 110 of the individual contact element rows 114 are oriented identically to one another or are arranged identically to one another.

[0078] The contact element 110 of the first plug connector part 102 (which is Figure 7 and Figure 8The base body 116 of the second plug connector part 104 (shown on the right in FIG) has a length 130 in the plug-in direction 108, which is greater than the contact element 110 of the second plug connector part 104 (which is shown on the right in FIG). Figure 7 and Figure 8 Length 130 of the base body (respectively shown on the left in FIG. 1 ) taken along the plug-in direction 108 .

[0079] exist Figure 1 and Figure 2 The plug connector components 102, 104 shown in FIG each have a plurality of first type contact elements 110A and a plurality of second type contact elements 110B. In particular, the contact element rows 114 each have a plurality of first type contact elements 110A and a plurality of second type contact elements 110B. Figure 3 、 4 and Figure 7 A first type of contact element 110A is shown in FIG. Figure 5 、 6 and Figure 8 A second type of contact element 110B is shown in FIG.

[0080] The base bodies 116 of the first type of contact elements 110A and the base bodies 116 of the second type of contact elements 110B of the respective plug connector parts 102, 104 are designed differently from one another and have different widths 132 in their respective main regions 122 in a lateral direction running perpendicularly to the plug-in direction 108 and perpendicularly to the row direction 112 (see Figure 7 and Figure 8 ).

[0081] At first end region 118, first-type contact elements 110A and second-type contact elements 110B are configured to be identical to one another. Furthermore, first- and second-type contact elements 110A, 110B are configured to be identical to one another at the second end region. Thus, first-type contact elements 110A and second-type contact elements 110B differ from one another only in main region 122.

[0082] exist Figure 5 、 6 and Figure 8 , the base body 116 of the second type of contact element 110B has a geometric structure 134 for impedance matching in the main region 122 of the base body 116, which is configured as a cross-sectional area reduction portion of the base body 116 in the main region 122 in the exemplary embodiment shown in the drawings. Figures 1 to 8 and Figures 10 to 17 In the second type of contact element 110B shown in FIG, the geometric structures 134 for impedance matching are arranged on opposite side sections of the main region 122 of the base body 116 .

[0083] In a top view along the arrangement direction 112 , the main region 122 of the base body 116 of the first type of contact element 110A is rectangular. Figure 3 、 4 and Figure 7 . Thus, the width 132 and / or the cross-sectional area of ​​the base body 116 of the first type contact element 110A is constant in the main region 122 between the first end region 118 and the second end region 120 .

[0084] exist Figures 1 to 8 In the second type of contact element 110B shown in FIG, the geometric structure 134 for impedance matching is arranged on two side sections of the main area 122 of the base body 116 and has two constricted areas 136 respectively, which is particularly Figure 8 . The impedance matching geometric structure 134 includes a first constriction region 136A, which is arranged on one side of the first end region 118 and constricts along the plugging direction 108. Furthermore, the impedance matching geometric structure 134 has a second constriction region 136B, which is arranged on one side of the second end region 120 and constricts opposite to the plugging direction 120. The two constrictions are arranged in a mirror-image manner relative to a mirror plane arranged perpendicular to the plugging direction 108.

[0085] The impedance matching geometry 134 of the second type contact element 110B of the first plug connector part 102 has a middle region 138 arranged between two tapered regions 136 , wherein the width 132 and / or the cross-sectional area of ​​the base body 116 of the second type contact element 110B is constant in this middle region 138 .

[0086] In the second type of contact element 110B of the second plug connector part 104 , the constricted regions 136 of the impedance matching geometry 134 transition into one another, wherein no intermediate region 138 is arranged between the constricted regions 136 (see Figure 5 、 6 and Figure 8 ).

[0087] exist Figure 1 and Figure 2In the illustrated connected or plugged state of the plug connector system 100, the contact elements 110 of the first plug connector part 102 (these are contact elements 110A of the first type) are plugged into the contact elements 110 of the second plug connector part 104 (these are contact elements 110A of the first type). In addition, the contact elements 110 of the first plug connector part 102 (these are contact elements 110B of the second type) are plugged into the contact elements 110 of the second plug connector part 104 (these are contact elements 110B of the second type).

[0088] It is possible that a plurality of contact elements 110 of each plug connector part 102, 104 are electrically connected in parallel. For example, a plurality of first type contact elements 110A can be electrically connected in parallel. In addition, a plurality of second type contact elements 110B can also be electrically connected in parallel.

[0089] Figure 9 Two contact elements 110B of the second type according to another embodiment are shown one after the other.
