Abstract
Description
[0001] Connector part and connector system
[0002] The invention relates to a connector part according to the preamble of claim 1 and a connector system.
[0003] Such connector parts typically comprise a plurality of contact elements for pluggable contact with contact elements of another connector part. The connector parts can be plugged into another connector part of a connector system along a plugging direction.
[0004] The contact elements of the connector parts can be arranged, for example, along a row direction running transversely to the plug-in direction in at least one row of contact elements and can have a base body which extends in a main extension plane which is arranged perpendicular to the row direction.
[0005] Such connector components are often used in so-called board-to-board connector systems. To improve signal or data transmission properties, it may be necessary to improve the impedance behavior of the connector components. However, the power transmission properties of the connector components should not be compromised if possible.
[0006] The object of the present invention is to provide a connector part which enables improved signal and energy transmission.
[0007] This object is achieved by an article having the features of claim 1.
[0008] Accordingly, the connector part has at least two contact elements whose base bodies are designed differently from one another.
[0009] The connector part is provided with at least two contact elements for pluggable contact with contact elements of another connector part, which are arranged along a row direction in at least one contact element row. The contact elements thus form (at least) one contact element row, along which the contact elements are arranged next to one another. The connector part can have one or more contact element rows, each comprising at least two contact elements.
[0010] In particular, the connector part together with another connector part can realize a so-called board-to-board connector, via which two printed circuit boards can be electrically connected to one another by plugging the associated connector parts together.
[0011] The connector part has at least two contact elements whose base bodies are designed differently from one another. In particular, each contact element row of the connector part can have at least two contact elements with different base bodies. By providing different contact elements in a contact element row, one or more contact elements can be provided that can be optimized for signal transmission and that are shaped, for example, for impedance matching for reflection-free signal transmission, and contact elements that are optimized for power transmission and, for example, have a conductor cross-section that allows even large currents to be transmitted.
[0012] Contact elements optimized for signal transmission can also be referred to as signal contacts. Contact elements optimized for energy transmission, on the other hand, can be referred to as power contacts.
[0013] In one embodiment, the connector part has at least two contact elements, the base bodies of which each have a different width in a transverse direction running perpendicular to the plugging direction and perpendicular to the arranging direction.
[0014] In one embodiment, the base bodies of the 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 end region and the second end region. For example, a respective 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 elements can have at least one contact lug for pluggable contact with an associated contact element of the further connector part.
[0015] The connector part can be mated with another connector part, for example, by moving both connector parts toward each other or by moving only one connector part toward the other connector part at a time. The mating direction can thus be defined for each connector part as a direction from the first end area to the second end area.
[0016] The contact lug can be configured, for example, as a contact pin or as a bent end of the contact element. The contact lug can be plugged into a corresponding contact lug of a corresponding contact element.
[0017] The at least two contact elements of the connector part preferably each have two contact lugs. A first contact lug can, for example, protrude away from the base body in the main extension plane of the base body, for example along the plug-in direction. In particular, the first contact lug can run entirely in the main extension plane of the base body. A second contact lug can also protrude away from the base body along the plug-in direction. For example, the second contact lug is arranged on the base body offset from the first contact lug in a direction running perpendicular to the plug-in direction and perpendicular to the alignment direction. For example, the second contact lug can be connected to the base body via a connecting section, in the region of which a bend is created, so that the second contact lug protrudes partially from the main extension plane of the base body in the alignment direction.
[0018] At the first end region of the base body of the contact elements, for example, a soldering area, such as a connection tab or soldering lug, for connection to a printed circuit board can be arranged. The connection tab or soldering lug can, for example, protrude away from the base body at the first end region perpendicular to the main extension plane of the base body. For example, the connection tab can be connected to the printed circuit board and to an electrical conductor track on the printed circuit board. For example, several or all of the contact elements of the connector part can be connected together to a printed circuit board. For this purpose, the printed circuit board can have connection points to which the contact elements are soldered, for example, so that the contact elements are, on the one hand, mechanically fastened to the printed circuit board and, on the other hand, are electrically contacted with the printed circuit board.
[0019] The contact lugs and the connecting lug or solder lug are preferably formed integrally with the base body of the respective contact element. The contact elements can be manufactured, for example, as a stamped and bent part, for example, from a sheet metal.
[0020] In one embodiment, the 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 body.
[0021] In one embodiment, the at least one contact element of the first type and the at least one contact element of the second type are configured identically to one another at the respective first end region and / or at the respective second end region of their base body. Thus, it is possible for the contact elements of the first type and the contact elements of the second type to differ from one another only in the main region.
[0022] In one embodiment, the base body of the at least one contact element of the second type has a geometry for impedance matching in the main region of the base body. In this way, the at least one contact element of the second type can, for example, realize a contact element that is optimized for signal transmission and can be referred to as a signal contact.
[0023] In one embodiment, the geometry for impedance matching is designed as a reduction in the cross-sectional area of the base body in the main region. Alternatively, it is conceivable for the geometry for impedance matching to be designed as an increase in the cross-sectional area of the base body in the main region.
[0024] Within the scope of this description and the appended claims, a cross-sectional area of the base body is, in particular, the area in the cross section of the base body of the at least one contact element along a cross-sectional plane extending perpendicular to the plug-in direction and is thus measured based on the resulting cross-sectional area (two-dimensional, determined by the width and material thickness). Within the scope of this description and the appended claims, a width of the base body is preferably a width taken perpendicular to the plug-in direction and perpendicular to the arranging direction.
[0025] In one embodiment, the geometry for impedance matching has at least one tapered region in which the width or a cross-sectional area of the base body of the at least one contact element of the second type tapers. For example, the geometry for impedance matching can have a first tapered region that is arranged on one side of the first end region and tapers in the plug-in direction. The geometry for impedance matching can further have, for example, a second tapered region that is arranged on one side of the second end region and tapers counter to the plug-in direction. The geometry for impedance matching can, for example, have two tapered regions that can be arranged, in particular, mirror-inverted to one another with respect to a mirror plane arranged perpendicular to the plug-in direction.A course of the geometry for impedance matching is preferably continuous in the at least one tapering region.
[0026] In one embodiment, the geometry for impedance matching has an intermediate region arranged between the two tapered regions. A width and / or a cross-sectional area of the base body is preferably constant in the intermediate region.
[0027] In one embodiment, the geometry for impedance matching extends uniformly, at least in some regions, along an extension direction of the main region between the first end region and the second end region. Here, the term "uniformly along an extension direction" can be understood as a profile in which lateral boundary edges of the main region each extend (approximately) in a straight line or in a curved line. For example, the width can change continuously; this results in a geometry that continuously widens or narrows (along the extension direction). Alternatively, the width can also remain constant, at least in some regions, and thus does not change along the extension direction; this results in a geometry of constant width.
[0028] Advantageously, the uniform geometry allows for simple and precise impedance matching. In one embodiment, the geometry for impedance matching is arranged on at least one side section of the main area of the base body of the at least one contact element of the second type. For example, a web-shaped material section can be arranged on the side section to increase the cross-sectional area, or a corresponding web-shaped cutout can be arranged in the side section to reduce the cross-sectional area depending on the desired impedance matching.
[0029] For example, the web-shaped section / cutout can be formed integrally with the material of the at least one contact element of the second type, or can have been incorporated into the production of the at least one contact element of the second type. Alternatively, the web-shaped section / cutout can also have been added / removed after the production of the at least one contact element of the second type.
[0030] In one embodiment, the geometry for impedance matching is arranged on opposite side sections of the main region of the base body of the at least one contact element of the second type. For example, two geometries for impedance matching are arranged mirror-inverted to each other on the side sections of the main region of the base body.
[0031] Advantageously, such a design allows for better counteracting of mechanical stresses on the at least one contact element of the second type, while at the same time an impedance adjustment can be carried out.
[0032] In one example, a minimum width of the main region comprising the impedance matching geometry is in a range of 0.6 mm to 1 mm, in particular 0.8 mm.
[0033] For example, a connector with such contact elements of the second type can have a pitch of 0.8 mm. In one example, the impedance drops to approximately 85 Ω at a minimum width of 1 mm. Advantageously, the impedance can be adjusted not only by changing the cross-sectional area, but also by changing the length of the main region, having the geometry for impedance adjustment. By changing the length, a uniform profile of the main region of the base body of the contact elements of the second type can be achieved in order to avoid larger disturbances. In one embodiment, a width-to-length ratio of the main region of the base body of the at least one contact element of the second type is in a range from 1:1.5 to 1:2.5, in particular 1:2.
[0034] Surprisingly, it has been shown that particularly good impedance matching results can be achieved with a width-to-length ratio of the main region of the base body of the at least one contact element of the second type of 1:2. Furthermore, it has been shown that the width-to-length ratio of the main region of the base body of the at least one contact element of the second type is easily scalable over a wide range for different applications. Therefore, by designing the at least one contact element of the second type with a width-to-length ratio of the main region of the base body in a range from 1:1.5 to 1:2.5, in particular at 1:2, a standardized contact element of the second type can be created that enables simple impedance matching.
[0035] In one embodiment, the base body of the at least one contact element of the first type and the base body of the at least one contact element of the second type each have a cross-sectional area in the main region, wherein the cross-sectional area of the base body of the at least one contact element of the second type is smaller than the cross-sectional area of the base body of the at least one contact element of the first type. Compared to the at least one contact element of the second type, the contact element of the first type thus has, at least at one axial location, in particular in the main region, a cross-sectional area (in cross-section along a cross-sectional plane perpendicular to the plugging direction) that is larger than the cross-sectional area of the contact element of the second type. The contact element of the first type can thus be optimized for energy transmission, whereas the contact element of the second type can be optimized for signal transmission.
[0036] The main region of the base body of the at least one contact element of the first type is preferably rectangular in a plan view along the row direction. A width and a cross-sectional area of the base body of the at least one contact element of the first type are thus preferably constant in the main region between the first end region and the second end region. In one embodiment, the at least one contact element row comprises a plurality of contact elements. For example, the at least one contact element row comprises 5, 10, 15, or more than 15 contact elements.
[0037] In one embodiment, the connector part has several, 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.
[0038] In one embodiment, contact lugs of the contact elements of a first contact element row and contact lugs of the contact elements of a second contact element row are arranged mirror-inverted to one another with respect to a mirror plane which runs parallel to the plugging direction and parallel to the row direction.
[0039] In one embodiment, the contact elements are hermaphroditic contact elements. Such hermaphroditic contact elements are known, for example, from WO 2019 / 291768 A1. Reference is therefore made in this regard to the patent application published as WO 2019 / 291768 A1, the content of which is hereby incorporated into this application.
[0040] Connector parts featuring hermaphroditic contact elements can be mated together to establish electrical contact between the contact elements. The hermaphroditic contact elements of the connector parts are designed to be identical in some areas, so that one connector part is not restricted to socket contacts and the other to pin contacts, as is usually the case. Instead, the hermaphroditic contact elements have both socket and pin properties.
[0041] Preferably, the contact lugs of the contact elements of a respective row of contact elements are aligned identically to one another or arranged identically to one another.
[0042] In one embodiment, each row of contact elements of the connector part has at least two contact elements whose base bodies are designed differently from one another. It is particularly conceivable for the rows of contact elements to each have contact elements of the first type and contact elements of the second type. For example, each row of contact elements can have several contact elements of the first type and several contact elements of the second type.
[0043] In one embodiment, several contact elements of the connector part are electrically connected in parallel. For example, several contact elements of the first type can be electrically connected in parallel. Furthermore, several contact elements of the second type can also be electrically connected in parallel.
[0044] The invention further relates to a connector system comprising a first connector part according to the invention and a second connector part according to the invention. The connector system can, for example, be a board-to-board connector system.
[0045] In a connected or plugged state of the connector system, contact elements of the first connector part can be plugged with contact elements of the second connector part, wherein the opposing and plugged contact elements of the two connector parts can be contact elements of the same type.
[0046] For example, contact elements of the first connector part, which are contact elements of the first type, can be plugged into contact elements of the second connector part, which are contact elements of the first type. Furthermore, for example, contact elements of the first connector part, which are contact elements of the second type, can be plugged into contact elements of the second connector part, which are contact elements of the second type.
[0047] It is conceivable that the base bodies of the contact elements of the first connector part have a length in the plug-in direction that differs from the length of the base bodies of the contact elements of the second connector part in the plug-in direction. For example, the base bodies of the contact elements of the first connector part can be longer in the plug-in direction than the base bodies of the contact elements of the second connector part.

[0061] Identical or functionally equivalent elements are provided with the same reference numerals in all figures.
[0062] Fig. 1 shows a connector system 100 comprising a first connector part 102 and a second connector part 104. The first connector part 102 and the second connector part 104 are not mated in Fig. 1, so the connector system 100 is shown in a non-connected state in Fig. 1. The connector system 100 may be a so-called board-to-board connector system 106.
[0063] Fig. 2 shows the connector system 100 from Fig. 1 in a connected or plugged state, in which the first connector part 102 and the second connector part 104 are plugged together along a plugging direction 108.
[0064] The connector parts 102, 104 each comprise a plurality of contact elements 110 for pluggably contacting the contact elements 110 of the respective other connector part 102, 104, such that the contact elements 110 of the first connector part 102 can be plugged into the contact elements 110 of the second connector part 104 along the plugging direction 108. The connector parts 102, 104 further each comprise a housing, which is not illustrated in the figures. For reasons of clarity, only individual contact elements 110 are identified by a reference numeral in Figs. 1 and 2. The connector parts 102, 104 can be plugged together, for example, by moving the two connector parts 102, 104 towards one another. Therefore, the plugging direction 108 is indicated by a double arrow in Figs. 1 to 6.
[0065] The contact elements 110 of the connector parts 102, 104 shown in Figs. 1 and 2 are arranged in two contact element rows 114 along a row direction 112 running transversely to the plugging direction 108. The two contact element rows 114 are arranged parallel to the row direction 112 and parallel to one another and each have 19 contact elements 110.
[0066] The contact elements 110 have a substantially planar extension. The contact elements 110 each have a base body 116 (see Figs. 3 to 6) that extends in a main plane of extension arranged perpendicular to the array direction 112. In the exemplary embodiments shown in the figures, the contact elements 110 are manufactured as a bent stamped part from a metal sheet.
[0067] The base bodies 116 of the contact elements 110 of the connector parts 102, 104 each have a first end region 118, a second end region 120, and a main region 122. The second end region 120 is opposite the first end region 118, and the main region 122 is arranged between the first end region 118 and the second end region 120.
[0068] At the first end region 118, the contact elements 110 are connected or connectable to a circuit board (not shown in the drawing). For this purpose, connection tabs 124 for connection to a circuit board are arranged at the first end region 118 of the base body 116 of the contact elements 110. The connection tabs 124 protrude at the first end region perpendicular to the main extension plane of the base body 116. The connection tabs 124 can, for example, be connected to an electrical conductor track of a circuit board. For this purpose, the circuit board can have connection points to which the contact elements 110 are soldered, for example, so that the contact elements 110 are, on the one hand, mechanically fastened to the circuit board and, on the other hand, are electrically contacted with the circuit board.
[0069] The contact elements 110 of the connector parts 102, 104 each have two contact lugs 126 on the second end region 120 (see Figs. 1, 2, 7 and 8). A first contact lug 126A projects away from the base body 116 in the main extension plane of the base body 116 in the plug-in direction 108 and runs entirely in the main extension plane of the base body 116. A second contact lug 126B also projects away from the base body 116 in the plug-in direction 108. The second contact lug 126B is arranged offset from the first contact lug 126A on the base body 116 in a direction perpendicular to the plug-in direction 108 and perpendicular to the arranging direction 112.The second contact lug 126B is connected to the base body 116 of the contact elements 110 via a connecting section 128, in the region of which a bend is created, so that the second contact lug 126B protrudes in the row direction 112 in some regions from the main extension plane of the base body 116.
[0070] The contact elements 110 are hermaphroditic contact elements, so that in principle two contact elements 110 which are of the same design at the second end region 120 of their base body 116 can be plugged together in order to establish an electrical contact between the contact elements 110.
[0071] The contact lugs 126 of the contact elements 110 of the first contact element row 114A and the contact lugs 126 of the contact elements 110 of the second contact element row 114B are arranged mirror-symmetrically with respect to a mirror plane that runs parallel to the plug-in direction 108 and parallel to the array direction 112. The contact lugs 126 of the contact elements 110 of a respective contact element row 114 are each aligned identically to one another or arranged identically to one another.
[0072] The base bodies 116 of the contact elements 110 of the first connector part 102, which are each shown on the right in Figs. 7 and 8, have a length 130 in the plug-in direction 108 which is greater than a length 130 taken in the plug-in direction 108 of the base bodies of the contact elements 110 of the second connector part 104, which are each shown on the left in Figs. 7 and 8.
[0073] The connector parts 102, 104 shown in Figs. 1 and 2 each have a plurality of contact elements 110A of a first type and a plurality of contact elements 110B of a second type. In particular, the contact element rows 114 each have a plurality of contact elements 110A of the first type and a plurality of contact elements 110B of the second type. Contact elements 110A of the first type are shown in Figs. 3, 4, and 7, while contact elements 110B of the second type are shown in Figs. 5, 6, and 8.
[0074] The base bodies 116 of the contact elements 110A of the first type and the base bodies 116 of the contact elements 110B of the second type of a respective connector part 102, 104 are designed differently from one another and have a different width 132 in their respective main region 122 in a transverse direction running perpendicular to the plugging direction 108 and perpendicular to the arranging direction 112 (see Figures 7 and 8). At the first end region 118, the contact elements 110A, 110B of the first and second types are designed identically to one another. Furthermore, the contact elements 110A, 110B of the first and second types are designed identically to one another at the second end region. Thus, the contact elements 110A of the first type and the contact elements 110B of the second type differ from one another only in the main region 122.
[0075] 5, 6, and 8 show that the base bodies 116 of the contact elements 110B of the second type have, in the main region 122 of the base bodies 116, a geometry for impedance matching 134, which in the exemplary embodiments shown in the figures is designed as a cross-sectional area reduction of the base body 116 in the main region 122. In the contact elements 110B of the second type shown in FIGS. 1 to 8 and 10 to 17, the geometry for impedance matching 134 is arranged on opposite side sections of the main region 122 of the base body 116.
[0076] The main region 122 of the base body 116 of the contact elements 110A of the first type is rectangular in a plan view along the array direction 112, as shown in Figs. 3, 4, and 7. The width 132 and / or a cross-sectional area of the base body 116 of the contact elements 110A of the first type are thus constant in the main region 122 between the first end region 118 and the second end region 120.
[0077] The geometry for impedance matching 134 is arranged on both side sections of the main region 122 of the base body 116 in the contact elements 110B of the second type shown in Figs. 1 to 8 and each has two tapered regions 136, as is shown in particular in Fig. 8. The geometry for impedance matching 134 has a first tapered region 136A, which is arranged on one side of the first end region 118 and tapers in the plug-in direction 108. The geometry for impedance matching 134 further has a second tapered region 136B, which is arranged on one side of the second end region 120 and tapers opposite to the plug-in direction 120. The two tapered regions are arranged mirror-symmetrically to one another with respect to a mirror plane arranged perpendicular to the plug-in direction 108.
[0078] The geometry for impedance matching 134 of the contact elements 11 OB of the second type of the first connector part 102 has an intermediate region 138 arranged between the two tapered regions 136, wherein the width 132 and / or a cross-sectional area of the base body 116 of the contact elements 11 OB of the second type is constant in the intermediate region 138.
[0079] The tapered regions 136 of the impedance matching geometry 134 merge into one another in the contact elements 110B of the second type of the second connector part 104, with no intermediate region 138 being arranged between the tapered regions 136 (cf. Figs. 5, 6 and 8).
[0080] In a connected or plugged-in state of the connector system 100 shown in Figs. 1 and 2, contact elements 110 of the first connector part 102, which are contact elements 110A of the first type, are plugged into contact elements 110 of the second connector part 104, which are contact elements 110A of the first type. Furthermore, contact elements 110 of the first connector part 102, which are contact elements 110B of the second type, are plugged into contact elements 110 of the second connector part 104, which are contact elements 110B of the second type.
[0081] It is possible for several contact elements 110 of a respective connector part 102, 104 to be electrically connected in parallel. For example, several contact elements 110A of the first type can be electrically connected in parallel. Furthermore, several contact elements 110B of the second type can also be electrically connected in parallel.
[0082] Figure 9 shows two contact elements 110B of the second type arranged one behind the other according to another exemplary embodiment. In contrast to the contact elements 110B of the second type shown in Figures 5, 6, and 8, the geometry for impedance matching 134, as a cross-sectional area reduction, is arranged only on one side section of the main region 122 of the base body 116 of the contact elements 110B.
[0083] 10 to 13 show views of contact elements 110B of the second type according to exemplary embodiments with different lengths of main regions 122 of the base bodies 116 of the contact elements 110B of the second type. In FIGS. 10 to 13 it is shown that a width-to-length ratio of the connecting regions 138 is different in each case. In the exemplary embodiments shown, the lengths 140 differ from one another, with the widths 142 remaining the same. This results in different values for the ratios in each case. FIGS. 14 and 15 show a multiplicity of contact elements 110B of the second type arranged one behind the other, as are provided, for example, in the plug connector parts 102, 104 shown in FIGS. 1 and 2. For the sake of clarity, no housing is shown in FIGS. 14 and 15.
[0084] In the embodiment shown in Figures 14 and 15, an air gap is arranged between adjacent contact elements 110B, and a width ratio of the width 142 of the air gap along the array direction 112 to a minimum width 132 of the main regions of the contact elements 110B is 1:1. In further embodiments, a plastic material can be arranged between adjacent contact elements 110B as a dielectric. When using a plastic material, a width ratio of a width 142 of the plastic material to a minimum width 132 of the main regions can be 0.5:1.
