[0001] Electrical connector and electronic module
[0002] Description
[0003] The present invention relates to an electrical connector for an electronic module. The present invention further relates to an electronic module comprising a printed circuit board and such an electrical connector.
[0004] State of the art
[0005] To protect electronic components from moisture, they can be potted, for example. Electrical connectors can also, in principle, be potted in this way. However, potting proves problematic for connectors that are to be fully assembled later and / or that need to be detachable later.
[0006] revelation
[0007] According to a first aspect, the invention proposes an electrical connector for an electronic module, comprising a first connector element that can be connected to a second connector element, and a housing for which an entry plane is defined or definable, wherein the first connector element is arranged at least partially within the housing, wherein, in particular, the course of an inner surface region of the housing and the course of an outer surface region of the first connector element are selected relative to each other such that an interaction between a foreseeable flowable potting compound and an air-filled space between the housing and the first connector element is reduced at least in certain areas, and thereby a capillary effect is reduced at least in certain areas.which reduces and / or limits the rise of the anticipated potting compound in the gap.
[0008] The invention is thus based on the surprising finding that, when potting an electrical connector, the potting compound can be reliably and safely kept away from critical components located inside the housing of the electrical connector by means of a suitable surface design of the housing and the first connector element. This prevents the potting compound from penetrating into the housing through small gaps due to capillary action. This can practically be described as an interruption (in the sense of a sufficiently high reduction) of the capillary effect.
[0009] In this way, it can be reliably prevented, in particular, that the potting compound flows into or surrounds the first connector element in such a way that it can no longer be connected to or detached from the second connector element (depending on whether the connection between the two connector elements already exists at the time of potting). This allows for particularly advantageous process control of the potting process.
[0010] This prevents the first connector element from becoming clogged with a connection area (such as a plug-in surface) provided inside the housing.
[0011] Furthermore, this method prevents an excess of potting compound in one area from leading to a deficiency elsewhere. This ensures a reliable and even distribution of the potting compound.
[0012] The proposed connector thus allows the first connector element to be partially potted together with the housing. This allows, for example, an opening in the housing located away from the entry point to be sealed against moisture. Nevertheless, a connection between the first and second connector elements can still be established and disconnected afterwards.
[0013] The provided potting compound is advantageously designed to close and / or seal against moisture an opening in the housing located away from the entry plane.
[0014] In particular, the air-filled space is limited at least partially by at least a part of the inner surface area of the housing and / or at least partially by at least a part of the outer surface area of the first connector element. In one embodiment, the inner surface area of the housing has a contour that deviates from a planar shape, in particular a curved shape, at least partially, and / or the outer surface area of the first connector element has a contour that deviates from a planar shape, in particular a curved shape, at least partially.
[0015] It is particularly advantageous (i) if the housing has or consists of polycarbonate, (ii) if the first connector element is designed as a pin header, in particular of the high-box type, and the second connector element is designed as a socket header, or the second connector element is designed as a pin header and the first connector element is designed as a socket header, (iii) if, in the connected state of the first and second connector elements, at least one electrically conductive connection is established between the first connector element and the second connector element and / or no locking connection is established, (iv) if the first connector element is designed as a mating part to the second connector element.and / or (v) if the first connector element is a male connector part and the second connector element is a female connector part, or the first connector element is a female connector part and the second connector element is a male connector part.
[0016] The potting compound is advantageously brought into contact with an opening of the air-filled cavity. The opening of the air-filled cavity is advantageously formed in an end section of the housing located away from the inlet plane. In particular, an edge of the opening of the air-filled cavity can define a plane that runs parallel to the inlet plane. When the opening of the air-filled cavity is brought into contact with the potting compound, the potting compound is advantageously in a state such that (particularly in the region of the opening of the air-filled cavity) no curing of the potting compound has yet begun, or curing of the potting compound is complete to less than 50%, in particular less than 30%, and in particular less than 10%.
[0017] The potting compound is advantageously supplied or supplyable from outside the housing. For example, when installing the electrical connector on a circuit board, the potting compound is advantageously applied from outside the housing and then flows into an area of the end section of the housing furthest from the entry plane, thus advantageously coming into contact with the opening of the air-filled cavity.
[0018] The flowable potting compound can, for example, be a polyurethane-based two-component system with adjustable flow behavior, where the two-component system can have a resin component and a hardener component.
[0019] When it is said that the effect of capillary action is reduced, this refers specifically to a reduction compared to a situation in which the two surface areas exhibit, or would exhibit, reference profiles. Similarly, when it is said that the rise height is reduced and / or limited, this refers specifically to a reduction and / or limitation compared to a situation in which the two surface areas exhibit, or would exhibit, reference profiles. These reference profiles could, for example, correspond to a planar profile of the two surface areas, where the two surface areas are in contact.
[0020] In particular, it is advisable to consider and assess the capillary action at a point in time, and thus in a state of the flowable potting compound, in which the potting compound is flowable, for example, when the flowable potting compound is intended and its curing is less than 10% complete. This does not preclude the possibility that at a later point in time (e.g., during subsequent use of the electrical connector), the intended, previously flowable potting compound may have hardened and no longer be flowable.
[0021] Furthermore, it can be advantageous, either alternatively or additionally, to consider and assess the capillary action at a time and in a state of the electrical connector where the housing is fluidically connected to its surroundings via the entry plane. This allows for reliable pressure equalization inside the housing.
[0022] A potting compound is considered to be flowable, in particular, if it exhibits capillary action in the space under consideration, at least temporarily, especially when the electrical connector is being assembled and / or when the potting compound has cured to less than 10%. Specifically, it can be verified whether the two surface areas of a given electrical connector exhibit capillary action similar to that of an electrical connector according to the first aspect of the invention. For this purpose, the rise of the potting compound in the air-filled space of the respective electrical connector can be determined and compared with the rise of the potting compound in an air-filled space between the two surface areas with a reference profile (approximately as described above).In other words, during the inspection, the two surface areas differ in their relative course to each other, whereas the materials of the surface areas and the potting compound remain unchanged.
[0023] Alternatively or additionally, it may also be provided that the electrical connector has the second connector element and / or that the second connector element is electrically connected or connectable to at least one electrical conductor which enters the housing through the entry plane in a connected state of the first and second connector elements.
[0024] For example, the housing may have an opening located in the entry plane. This opening provides access to an interior space enclosed by the housing. For instance, the second connector element can also be inserted into the housing through this opening (and via the entry plane) to connect to the first connector element.
[0025] The interior space may contain at least a partial connector element and / or the full connector element.
[0026] Particularly when the first and second connector elements are assembled, a connection area exists between them within the interior. This connection area may, for example, include a mating surface that can be part of either the first or second connector element.
[0027] Alternatively or additionally, the housing can also be sealed by means of a sealing element, particularly one arranged in the entry plane, in particular by means of a positive-locking seal, wherein the at least one electrical conductor extends through the sealing element. The sealing element can seal the housing at least partially. In particular, the sealing element can be arranged at least partially within the opening located in the entry plane and thereby seal it.
[0028] The sealing element can be made of silicone, for example, in particular a silicone cushion.
[0029] This allows the housing, together with the sealing element and the potting compound, to advantageously form a completely sealed interior for the components arranged within, such as the first and / or second connector elements. In particular, the electrical connector can be sealed with potting compound and sealing element by two sealing measures that can be carried out independently of each other, either spatially or temporally. This increases flexibility.
[0030] This makes the electrical connector particularly suitable for subsequent sealing. Subsequent sealing can offer a cost advantage, as the first and second connector elements and / or the connection made or that can be made between the first and second connector elements do not necessarily need to be sealed.
[0031] In particular, the surface area of the sealing element can correspond to an opening area of the housing and close this opening area. The opening area does not have to be as large as the maximum area defined by the outer circumference of the housing.
[0032] Alternatively or additionally, it can also be provided that a first gap is formed between the inner surface area of the housing and the outer surface area of the first connector element at a first level position of the electrical connector along a first direction, and that a second gap is formed at a second level position, offset in the direction of the entry plane with respect to the first level position, along the first direction, wherein the first gap is smaller than the second gap.
[0033] This physical design of the surface areas allows for a particularly reliable reduction in capillary action and, consequently, in the rise height. Advantageously, the housing has a smaller dimension along the first direction and / or a smaller circumference at the first level position than at the second level position. This also allows for a space saving (especially in the area of a printed circuit board to which the housing and / or first connector element is connected).
[0034] The choice of the first and second distances therefore advantageously serves to reduce the interaction between the foreseeable flowable potting compound and the air-filled space between the housing and the first plug-in connector element, at least in some areas, and thereby reduce the effect of capillary action, at least in some areas, thus reducing and / or limiting the rise height of the foreseeable potting compound in the space.
[0035] In particular, the reduced effect of capillary action limits the rise height of the potting compound in the space, especially up to the first level position.
[0036] It is particularly advantageous if the first level position is located further away from the entry plane than a connection area of the first connector element. In this connection area, for example, an electrical connection between the first and second connector elements can be established. The connection area is, for example, a mating surface.
[0037] In embodiments, a plugging surface of the first connector element and / or the second connector element is arranged between the first level position and the second level position, in particular in a connected state of the first and second connector elements.
[0038] In particular, the specific area can be located at the level of the first level position.
[0039] In embodiments, a first surface enclosed within the housing in a cross-sectional plane lying at the first level position is between 50 mm 2 and 200 mm 2 , especially between 100 mm 2 and 150 mm 2 , large. In embodiments, the second surface enclosed within the housing in a cross-sectional plane lying at the second level position is between 100 mm 2 and 250 mm 2 , especially between 120 mm 2 and 200 mm 2 , large. In particular, the first area is smaller than the second area. For example, the ratio of the first and second areas can be between 0.2 and 0.9, especially between 0.4 and 0.8. Alternatively or additionally, the first and second areas can also be identical in size.
[0040] In embodiments, a third surface enclosed by an outer contour of the first connector element in a cross-sectional plane lying at the first level position is between 50 mm 2 and 200 mm 2 , especially between 80 mm 2 and 130 mm 2 , large. In embodiments, a fourth surface enclosed by an outer contour of the first connector element in a cross-sectional plane lying at the second level position is between 30 mm. 2 and 150 mm 2 , especially between 100 mm 2 and 150 mm 2 , large. In particular, the third area is larger than the fourth area. For example, the ratio of the third and fourth areas can be between 1.1 and 1.9, especially between 1.2 and 1.5. Alternatively or additionally, the third and fourth areas can also be identical in size.
[0041] For example, the ratio of the first area to the third area could be 1.05.
[0042] For example, the ratio of the second area to the fourth area could be 1.30.
[0043] In particular, the first / second distance is measured perpendicularly between the two surface areas. This means, specifically, that a connecting line between the two surface areas, whose length corresponds to the first / second distance, runs perpendicular to both surface areas.
[0044] A level position can, for example, define a plane. The planes defined in this way can, for example, extend parallel to the entry plane. In particular, the planes of different level positions are offset from each other along a direction perpendicular to the entry plane. For example, in embodiments, each level position can describe a vertical height of the electrical connector.
[0045] Alternatively or additionally, the housing can be designed to be at least partially transparent to light of at least one wavelength, for checking the positioning and / or orientation of the first connector element, the positioning and / or orientation of the first connector element relative to the second connector element, and / or the positioning and / or orientation of the sealing element, each within the housing. This allows for particularly simple yet reliable verification of the correct positioning and / or orientation of the components within the housing. This enables particularly advantageous process control, especially before, after, and during potting.
[0046] Especially during potting, correct positioning and alignment, particularly of the first connector element, can be crucial. The transparent housing therefore offers a particularly advantageous way to check this.
[0047] Furthermore, the transparent housing allows for the advantageous use of electrical connectors without a locking mechanism, as their correct assembly can be reliably verified afterward. In particular, the connection between the first and second connector elements features either a push-fit connection and / or a non-locking connection. By eliminating the need for a locking tab, for example, space savings are possible.
[0048] For example, the housing can be transparent to light of at least one wavelength from the ultraviolet (UV), visible (VIS) and / or infrared (IR) wavelength range.
[0049] For example, the electrical connector can be inspected using a camera and / or AI image recognition, either once or after different assembly steps. The light-transmitting housing thus offers a particular advantage in the manufacturing process.
[0050] It is advisable to carry out the inspection in an assembled state of the electrical connector and / or in a connected state between the first and second connector elements.
[0051] Alternatively or additionally, it can also be provided that the first distance is a dimension of a slit-shaped gap between the two surface areas.
[0052] In particular, the gap between the two surface areas is considered slit-like if the initial distance between the two surface areas is less than 1 mm and / or if the gap is caused by irregularities in the surface areas at a microscopic level, especially in the case of contacting surface areas. The same applies, conveniently, to the distances mentioned below in connection with gaps.
[0053] If the first distance is a dimension of a slit-shaped gap between the two surface areas, the specific value of the dimension or the first distance is generally not important, especially if the first distance only serves for comparison with another quantity and the relationship between the comparison quantities is apparent even without a specific value of the dimension or the first distance.
[0054] Alternatively or additionally, it may also be provided that a third distance is formed between the two surface areas at the first level position along a second direction perpendicular to the first direction, and a fourth distance is formed at the second level position along the second direction, wherein the third distance is smaller than the fourth distance and / or the third distance and / or the fourth distance are each a dimension of a respective slit-shaped space between the two surface areas.
[0055] This physical design of the surface areas allows the reduction of capillary action and thus the reduction of the rise height to be achieved particularly reliably along the further or other second direction.
[0056] Advantageously, the housing has a smaller extent along the second direction and / or a smaller circumference at the first level position than at the second level position. This also allows for a space saving (especially in the area of a printed circuit board to which the housing and / or first connector element is connected).
[0057] The selection of the third and fourth distances therefore advantageously serves to reduce, at least in certain areas, the interaction between the intended flowable potting compound and the air-filled gap between the housing and the first connector element, thereby reducing the effect of capillary action, at least in certain areas, and thus reducing and / or limiting the rise of the intended potting compound in the gap. In particular, the third / fourth distance is measured perpendicularly between the two surface areas. This means, specifically, that a connecting line between the two surface areas, the length of which corresponds to the third / fourth distance, runs perpendicular to both surface areas.
[0058] If the third / fourth distance is a dimension of a slit-shaped space between the two surface areas, the specific value of the dimension or the third / fourth distance is generally not important, especially if the third / fourth distance only serves for comparison with another quantity and the relationship between the comparison quantities is evident even without a specific value of the dimension or the third / fourth distance.
[0059] In embodiments, the first, second, third and fourth distances can also be dimensions of one and the same space, for example in the form of a circumferential space.
[0060] Alternatively or additionally, it may also be provided that the inner surface area of the housing has a curved and / or stepped profile in at least one area between the first level position and the second level position, and in particular that the first and second distances and / or the third and fourth distances are at least partially determined by the profile.
[0061] In other words, the interior of the housing can expand. This is a particularly simple yet reliable way to advantageously reduce capillary action and, consequently, the rise height.
[0062] In some embodiments, the connection area is located at the level of the curved and / or stepped profile.
[0063] Advantageously, the pattern is also followed by an outer surface of the housing. This allows for a space saving.
[0064] However, it is also possible, alternatively or additionally, for the outer surface area of the first connector element to have a curved and / or stepped profile in at least one area between the first and second level positions, and for the profile to at least partially determine the first and second distances and / or the third and fourth distances. Alternatively or additionally, it may also be provided that an inner contour of the housing has a funnel-shaped profile in at least one cross-sectional plane of the electrical connector, and for the profile to at least partially determine the first and second distances and / or the third and fourth distances.
[0065] In other words, the interior of the housing can expand. This is a particularly simple yet reliable way to advantageously reduce capillary action and, consequently, the rise height.
[0066] In some embodiments, the connection area is located at the level of the funnel-shaped section.
[0067] Advantageously, the pattern is also followed by an outer surface of the housing. This allows for a space saving.
[0068] For example, the contour can be created by intersecting the inner surface of the housing (which corresponds, in a sense, to an outer surface of the interior) with the cross-sectional plane. The contour does not have to be closed and can, for example, have a first and a second part (such as a left and a right half).
[0069] The cross-sectional plane advantageously runs perpendicular to the entry plane. Alternatively or additionally, the cross-sectional plane runs perpendicular to the first direction and / or parallel to the second direction.
[0070] Alternatively or additionally, it may also be provided that the outer surface area of the first plug-in connector element has a flat profile between the first level position and the second level position.
[0071] However, it is also possible, alternatively or additionally, that the inner surface area of the housing has a flat profile between the first level position and the second level position.
[0072] Alternatively or additionally, it may also be provided that an internal dimension of the housing at the first level position along the first direction is smaller than a corresponding internal dimension of the housing at the second level position along the first direction and / or an external dimension of the first connector at the first level position along the first direction is larger than a corresponding external dimension of the first connector at the second level position along the first direction, that an internal dimension of the housing at the first level position along the second direction is smaller than a corresponding internal dimension of the housing at the second level position along the second direction and / or an external dimension of the first connector at the first level position along the second direction is larger than a corresponding external dimension of the first connector at the second level position along the second direction.that an internal dimension of the housing at the first level position along the first direction is identical to a corresponding internal dimension of the housing at the second level position along the first direction, and / or an external dimension of the first connector at the first level position along the first direction is identical to a corresponding external dimension of the first connector at the second level position along the first direction, and / or that an internal dimension of the housing at the first level position along the second direction is identical to a corresponding internal dimension of the housing at the second level position along the second direction, and / or an external dimension of the first connector at the first level position along the second direction is identical to a corresponding external dimension of the first connector at the second level position along the second direction.
[0073] For example, the internal dimension of the case can be the extent of the interior along the respective first or second direction. For example, the internal dimension of the case is the internal width (along one direction) or internal depth (along the other direction) of the case.
[0074] For example, the outer dimension of the first connector can be its extent along the respective first or second direction. For example, the outer dimension of the first connector is its width (along one direction) or depth (along the other direction).
[0075] Alternatively or additionally, it may also be provided that the housing is at least partially slid or can be slid onto the first connector element, in particular by forming a force-fit connection between the housing and the first connector element, and / or wherein the first connector element can be mechanically coupled to a printed circuit board by forming at least one electrically conductive connection between the first connector element and the printed circuit board, in particular by means of a soldered connection, a screw connection and / or an adhesive connection.
[0076] According to a second aspect, the invention proposes an electronic module comprising a printed circuit board and an electrical connector according to the first aspect of the invention, wherein the first connector element of the electrical connector is mechanically coupled to the printed circuit board by forming at least one electrically conductive connection between the first connector element and the printed circuit board, in particular by means of a soldered connection, a screw connection and / or an adhesive connection.
[0077] All the advantages described with regard to the electrical connector according to the first aspect of the invention also apply accordingly to the electronic module according to the second aspect of the invention. Therefore, reference can be made here to the preceding explanations.
[0078] The features described in relation to the electrical connector according to the first aspect of the invention can also be provided accordingly in the electronic module, individually and in any combination, unless otherwise indicated by the context.
[0079] In particular, the physical and functional configurations of the individual parts described in connection with the electrical connector according to the first aspect of the invention, as well as the described structural and functional relationships between the individual parts, can also be provided accordingly in the electronic module, individually and in any combination, unless otherwise indicated by the context.
[0080] Alternatively or additionally, it may also be provided that the printed circuit board, the first connector element, and the housing of the electrical connector, in particular a section of an end of the housing located away from the entry plane, especially opposite the entry plane, are each at least partially enclosed in a potting compound and / or cannot be separated from each other without destruction.
[0081] This allows for a particularly advantageous seal against moisture. During manufacturing, the potting compound is expediently applied from outside the housing and then flows into an area of an end section of the housing furthest from the inlet plane.
[0082] For example, the first connector element can be attached to the circuit board, then the housing can be slid on, and then the assembly consisting of the first connector element, circuit board and housing can be potted, at least in some areas.
[0083] Further features and advantages of the invention will become apparent from the following description, in which embodiments of the invention are explained with reference to schematic drawings. These show:
[0084] Fig. 1 is a schematic perspective representation of an electronic module according to the second aspect of the invention;
[0085] Fig. 2 is a schematic perspective exploded view of parts of the electronics module from Fig. 1;
[0086] Fig. 3 shows a schematic cross-sectional view of the electronics module from Fig. 1 in a first cross-sectional plane;
[0087] Fig. 4 shows another schematic cross-sectional view of the electronics module from Fig. 1 in the first cross-sectional plane;
[0088] Fig. 5 is an enlarged view of a section from Fig. 4;
[0089] Fig. 6 shows a schematic cross-sectional view of the electronics module from Fig. 1 in a second cross-sectional plane; and
[0090] Fig. 7 is an enlarged view of a section from Fig. 6.
[0091] Fig. 1 shows a schematic perspective view of an electronic module 1 according to the second aspect of the invention. The electronic module 1 has a printed circuit board 3 and an electrical connector 5 according to the first aspect of the invention.
[0092] Fig. 2 shows a section of a schematic perspective exploded view of parts of the electronic module 1, in which the components of the electrical connector 5 are particularly easy to see. For the sake of simplicity, some elements of the electronic module 1 have been omitted. The electrical connector 5 has a first connector element 7 and a second connector element 9. The electrical connector 5 also has a housing 11. An entry plane E (shown as a dashed line) is defined for the housing 11.
[0093] The first connector 7 is at least partially located within the housing 11. In the connected state of the first and second connectors 7 and 9 shown in Fig. 1, the second connector 9 is also located within the housing 11. The second connector 9 is electrically connected to several electrical conductors 13. The electrical conductors 13 enter the housing 11 through the entry plane E.
[0094] The housing 11 is sealed by means of a sealing element 15 arranged in the entry plane E. The electrical conductors 13 extend through the sealing element 15.
[0095] The first connector element 7 is attached to the circuit board 3 and electrically connected to it.
[0096] Fig. 3 shows a schematic cross-sectional view of the electronic module 1 in a first cross-sectional plane QE1. The first cross-sectional plane QE1 is perpendicular to the entry plane E. In addition, in a region 17 of an opening 19 of the housing 11 located away from the entry plane E, the first connector element 7, the housing 11 and the circuit board 3 are encapsulated in a potting compound 21 (shown with dashed lines).
[0097] Fig. 4 shows another schematic cross-sectional view of the electronic module 1 in the first cross-sectional plane QE1, but without a schematic representation of the potting compound 21. The sealing element 15 and the potting compound reliably seal an interior space 23 of the housing 11, in which the first and second connector elements 7 and 9 are provided, against moisture. At the same time, with a reversibly removable sealing element 15, the interior space 23 is also accessible and resealable at any time by removing the sealing element 15 from the housing 11 and then repositioning it in the entry plane E.
[0098] Fig. 5 shows an enlarged view of a section 33 from Fig. 2
[0099] The housing 11 has an inner surface area 25 (in this case, this corresponds to the entire inner surface) and the first connector element 7 has an outer surface area 27 (in this case, this corresponds to the entire outer surface). Figures 5 and 7 show the intersection lines of surface areas 25 and 27 with the respective cross-sectional planes QE1 and QE2.
[0100] To prevent the (then) flowable potting compound 21 (not shown in Figs. 5 and 7) provided in area 17 from rising too high due to capillary action between the housing 11 and the first connector element 7 (and then, for example, clogging a mating surface 29 of the first connector element 7), the profiles of the two surface areas 25 and 27 relative to each other are specifically chosen. This is done in such a way that an interaction between the flowable potting compound 21 (in Fig.5 and 7 not shown) and an air-filled gap 31 between the housing 11 and the first plug-in element 7 (at least before potting) is reduced at least in some areas, thereby reducing the effect of capillary action at least in some areas, which reduces and / or limits the rise H of the foreseeable potting compound 21 in the gap 31 (by at least partially displacing the air contained therein) (in comparison to a situation in which the two surface areas 25 and 27 are in continuous contact and are flat).
[0101] Due to the relative profiles of the surface areas 25 and 27, a first gap D1 is formed between the inner surface area 25 of the housing 11 and the outer surface area 27 of the first connector element 7 at a first level position NP1 of the electrical connector 5 along a first direction R1. Furthermore, a second gap D2 is formed at a second level position NP2, which is offset relative to the first level position NP1 in the direction of the entry plane, along the first direction R1. The first gap D1 is smaller than the second gap D2.
[0102] The first distance D1 is a dimension of the slit-shaped space 31 between the two surface areas 25 and 27. Due to their small values, only circles of the respective areas are provided in Fig. 5 for the first distance D1 and the second distance D2, in which the first distance D1 or the second distance D2 is formed and can be measured.
[0103] Fig. 6 shows a schematic cross-sectional view of the electronic module 1 from Fig. 1 in a second cross-sectional plane QE2. The second cross-sectional plane QE2 is perpendicular to the entry plane E and the first cross-sectional plane QE1.
[0104] Fig. 7 shows an enlarged view of a section 39 from Fig. 6.
[0105] Furthermore, a third distance D3 is formed between the two surface areas 25 and 27 at the first level position NP1 along a second direction R2 perpendicular to the first direction R1, and a fourth distance D4 is formed at the second level position NP2 along the second direction R2. The third distance D3 is smaller than the fourth distance D4.
[0106] The third distance D3 is a (different) dimension of the slit-shaped space 31 between the two surface areas 25 and 27. Due to their small values, only circles of the respective areas are provided in Fig. 7 for the third distance D3 and the fourth distance D4, in which the third distance D3 or the fourth distance D4 is formed and can be measured.
[0107] The first, second, third, and fourth distances D1, D2, D3, and D4 are each at least partially determined by a curved profile of the inner surface area 25 of the housing 11 in a region between the first level position NP1 and the second level position NP2. An inner contour 43 of the housing 11 thus has a funnel-shaped profile in both cross-sectional planes QE1 and QE2. In other words, the width and depth of the interior space in the housing increase with height in the direction of the entry plane E.Due to this constructive design measure of the housing 11, an internal dimension 11 of the housing 11 at the first level position NP1 along the first direction R1 is smaller than a corresponding internal dimension I2 of the housing 11 at the second level position NP2 along the first direction R1, and an internal dimension I3 of the housing 11 at the first level position NP1 along the second direction R2 is smaller than a corresponding internal dimension I4 of the housing 11 at the second level position NP2 along the second direction R2.
[0108] Through this constructive design measure of the first plug-in connector 7, an outer dimension of the first plug-in connector 7 is advantageously identical at the first level position NP1 along the first direction R1 to a corresponding outer dimension of the first plug-in connector 7 at the second level position NP2 along the first direction R1, and an outer dimension of the first plug-in connector 7 at the first level position NP1 along the second direction R2 is identical to a corresponding outer dimension of the first plug-in connector 7 at the second level position NP2 along the second direction R2.
[0109] An outer surface 45 of the housing 11 mirrors the widening inside the housing 11, thereby achieving a space saving, particularly in the area near the circuit board 3. In other words, the width and depth of the housing 11 increase upwards (towards the entry plane E).
[0110] The outer surface area 27 of the first connector element 7 between the first level position NP1 and the second level position NP2 has a flat profile.
[0111] In embodiments, the housing 11 can be transparent to light of at least one wavelength, at least in certain areas. This can be advantageous for checking the positioning and / or orientation of the first connector element 7, the positioning and / or orientation of the first connector element 7 relative to the second connector element 9, and / or the positioning and / or orientation of the sealing element 15, each within the housing 11.
[0112] An electronic module according to the second aspect of the invention, such as the electronic module 1 described above with reference to Figures 1-7, can be manufactured simply yet reliably. For example, the following manufacturing method can be used: - A first connector element is mechanically and / or electrically coupled to a conductor plate, for example by means of a soldered connection.
[0113] - A housing is slid onto the first connector element.
[0114] - The circuit board, the first connector element, and the housing are at least partially potted together in a potting compound. An opening in the housing, located away from an entry point, is sealed. - A second connector element, connected to electrical leads, is inserted into the housing, and an electrically conductive connection is established between the two connector elements.
[0115] - A sealing element seals the entrance level of the housing. The electrical conductors extend through this sealing element.
[0116] The features disclosed in the preceding description, in the drawings and in the claims can be essential to the invention in its various embodiments, both individually and in any combination.
[0117] Furthermore, at least one further invention relates to an electrical connector for an electronic module, comprising a housing and a sealing element that can be inserted into the housing for sealing an opening of the housing against the ingress of splashing water, in particular by means of a positive fit. This also relates to an electronic module comprising a printed circuit board and such an electrical connector, wherein the first connector element of the electrical connector is mechanically coupled to the printed circuit board by forming at least one electrically conductive connection between the first connector element and the printed circuit board, in particular by means of a soldered connection, a screw connection and / or an adhesive connection.
[0118] Connectors with a sealed housing are known in the prior art. The connector is surrounded by a sealing housing and a gasket. These two parts seal the connector. To prevent accidental disconnection due to overpressure inside the housing, the connectors often feature a locking mechanism.
[0119] According to a third aspect, the invention relates to an electrical connector for an electronic module, comprising a housing and a sealing element that can be inserted into the housing for sealing an opening of the housing against the ingress of splashing water, particularly by means of a positive fit. According to the invention, the housing has a projection for deforming the sealing element to allow, in particular at least partial, pressure equalization between a volume enclosed by the housing and the surrounding environment after and / or at least temporarily during the insertion of the sealing element into the housing. In this way, overpressure in the volume can be reliably avoided. This is because air that is trapped in the volume enclosed by the housing when the sealing element is inserted can reliably escape into the environment due to the deformation of the sealing element.Due to the resulting pressure equalization, the sealing element remains reliably within the housing. Since the build-up of overpressure inside the housing is prevented, the sealing element is no longer forced out by any pressure build-up. This ensures a consistent seal and connection even under temperature fluctuations. Surprisingly, achieving this effect requires, in principle, only a slight change in the housing geometry, resulting in the sealing element becoming sufficiently deformable. This allows for a secure and reliable seal of the housing in a simple and cost-effective manner.
[0120] The deformation of the sealing element is advantageously reversible.
[0121] The sealing element is advantageously reversibly deformable, particularly when interacting with the projection. For example, the sealing element can be made of a reversibly deformable material. This allows the sealing element to be deformed by interacting with the projection and to return to its original shape after the interaction ends. For example, the sealing element is made of silicone. The sealing element can be a silicone cushion.
[0122] The opening is advantageously bounded by an edge of the housing and / or expediently allows access to the volume enclosed by the housing. The opening has, for example, specific dimensions, such as a length and width (in the case of a rectangular opening geometry) or a diameter (in the case of a circular opening geometry). In one embodiment, it is provided that the sealing element can be inserted into the housing, particularly along a direction of movement, and that, when the sealing element is inserted into the housing, air can escape at least partially from the volume enclosed by the housing into the surroundings, particularly substantially against the direction of movement and / or via the opening, by deformation of the sealing element through the projection.Advantageously, this creates an interaction between the projection and the sealing element, allowing the air trapped in the volume to escape. The deformation of the sealing element by the projection can be facilitated if the sealing element is made of, or contains, a reversibly deformable material.
[0123] In one embodiment, an entry plane is defined or definable for the housing, and in particular, the opening of the housing is arranged in the entry plane. Advantageously, this entry plane allows access to the volume enclosed by the housing.
[0124] In one embodiment, the main extension direction of the projection is perpendicular to the entry plane. This advantageously enables particularly good interaction between the projection and the sealing element, especially over a comparatively long distance along the direction of movement. For example, the projection has its greatest extent in its main extension direction.
[0125] The direction of movement is expediently parallel to the main direction of extension.
[0126] In one embodiment, the end of the projection facing the housing opening is spaced apart from the opening and / or the entry plane. This advantageously allows for initial positioning of the sealing element within the housing's entry area. For example, the sealing element can rest on the projection during initial positioning. This provides haptic feedback to the operator confirming correct positioning. From this initial position, the sealing element can then be reliably inserted further into the housing until a final position is reached.
[0127] In one embodiment, the end section of the projection facing the housing opening has a curved surface area to facilitate insertion of the sealing element into the housing. This advantageously enables simple and reliable insertion of the sealing element into the housing. The end section of the projection can, for example, form a sliding surface along which the sealing element can be guided during insertion into the housing. Advantageously, the curvature of the curved surface area runs, at least in part, parallel to the direction of movement.
[0128] In one embodiment, the projection, particularly a section of the projection arranged beyond the end section facing the opening of the housing in the direction of movement, has an outer contour that is at least partially rectangular in a cross-sectional plane, particularly one parallel to the inlet plane. This advantageously prevents the sealing element from coming into complete contact with the projection. In this way, gaps can be created between the sealing element and the projection, thus ensuring reliable pressure equalization.
[0129] In one embodiment, the sealing element is provided to have at least two sealing lips, a first sealing lip and a second sealing lip. This advantageously enables several defined contact points between the sealing element and the housing.
[0130] The sealing element can, for example, have a base body, with the sealing lips circumferencing the base body at least partially. The sealing lips are advantageously spaced apart from each other in the direction of movement. For example, in the direction of movement, the second sealing lip follows the first.
[0131] Optionally, the sealing element has at least three sealing lips, i.e., in addition to the first and second sealing lips, a third sealing lip.
[0132] In one embodiment, after the sealing element is inserted into the housing, the first sealing lip is arranged in the entry plane and / or rests against an edge of the housing, in particular an edge defining the opening, especially to seal the opening of the housing against the ingress of splashing water. This advantageously achieves water protection. The first sealing lip can, for example, rest on the edge of the housing. This allows the opening to be reliably sealed along its entire edge.
[0133] In one embodiment, after the sealing element is inserted into the housing, the first sealing lip, together with the housing, and in particular its edge, forms a valve, especially a check valve, which allows air to escape from the volume enclosed by the housing, particularly through the opening, into the surrounding environment. This advantageously enables the equalization of pressure differences, for example, due to temperature changes or during transport in an aircraft. At the same time, this advantageously does not impair, or at most only minimally impairs, the watertight function. Because of the way a check valve works, while air can escape from inside the housing to the outside, splash water from the outside is advantageously prevented from penetrating the interior of the housing.
[0134] In one embodiment, it is provided that after and / or at least temporarily during the insertion of the sealing element into the housing, the second sealing lip is deformed or deformable at least partially by the projection, in particular such that after and / or at least temporarily during the insertion of the sealing element into the housing, air, especially substantially against the direction of movement and / or via the opening, can escape from the volume enclosed by the housing into the surrounding environment. This advantageously supports pressure equalization.
[0135] For example, as mentioned above, the sealing element can also have more than two sealing lips, for example, three sealing lips (in addition to the first and second sealing lips, also a third sealing lip). In this case, at least two of the three sealing lips (for example, at least the second and third sealing lips) can be deformed or deformable, at least partially, by the projection after insertion and / or at least temporarily during the insertion of the sealing element into the housing.
[0136] In one embodiment, it is provided that after the sealing element is inserted into the housing and / or at least temporarily during the insertion process, the second sealing lip bears against the housing, in particular against an inner surface of the housing, in a force-fit manner. Advantageously, this achieves both water protection and a holding force through friction.
[0137] In one embodiment, it is provided that after and / or at least temporarily during the insertion of the sealing element into the housing, the second sealing lip is deformed or deformable by the projection, at least in certain areas, such that after and / or at least temporarily during the insertion of the sealing element into the housing, air, particularly against the direction of movement and / or via the opening, can escape from the volume enclosed by the housing into the surrounding environment. This advantageously supports pressure equalization.
[0138] In one embodiment, the electrical connector is designed without a locking mechanism. This advantageously enables a particularly simple and cost-effective connector to be manufactured. Due to the pressure equalization facilitated by the projection, an additional locking mechanism to prevent the sealing element from being forced out due to overpressure is no longer necessary.
[0139] In one embodiment, an outer dimension, such as a width or thickness, of a region of the sealing element is larger than an inner dimension, such as an inner width or thickness, of a region of the housing. After the sealing element is inserted into the housing, an outer surface of the sealing element region is in contact with an inner surface of the housing region. This advantageously ensures a reliable fit of the sealing element in the housing. Consequently, an interference fit can be advantageously achieved between the sealing element and the housing.
[0140] In one embodiment, the projection is provided on an inner surface of the housing, which inner surface in particular at least partially defines the enclosed volume, and / or protrudes from it, and / or is formed integrally with the housing. This advantageously enables simple manufacturing of the housing including the projection. For example, the housing can be manufactured by injection molding.
[0141] In one embodiment, the housing has one or more additional openings that are fluid-tight or sealable, in particular potted or pottable with a potting compound. This advantageously enables simple electrical connection of the electrical connector to, for example, a printed circuit board. This is because parts of the connector can, for example, be arranged on the printed circuit board and protrude into the housing through the additional opening.
[0142] The one or more additional openings are advantageously arranged outside the entry plane. The one or more additional openings are advantageously provided differently and / or at a distance from the opening that is sealed or sealable by means of the sealing element.
[0143] In one embodiment, the electrical connector has a first connector element that can be connected to a second connector element, and the first connector element is at least partially located inside the housing. This advantageously provides splash protection for both the first and second connector elements.
[0144] It is particularly advantageous (i) if the housing has or consists of polycarbonate, (ii) if the first connector element is designed as a pin header, in particular of the high-box type, and the second connector element is designed as a socket header, or the second connector element is designed as a pin header and the first connector element is designed as a socket header, (iii) if, in the mated state of the first and second connector elements, at least one electrically conductive connection is established between the first connector element and the second connector element and / or no locking connection is established, (iv) if the first connector element is designed as a mating part to the second connector element.and / or (v) if the first connector element is a male connector part and the second connector element is a female connector part, or the first connector element is a female connector part and the second connector element is a male connector part.
[0145] In one embodiment, it is provided that the electrical connector has the second connector element and / or that the second connector element is electrically connected or connectable to at least one electrical conductor which enters the housing through the entry plane in a connected state of the first and second connector elements.
[0146] For example, the second connector element can be inserted into the housing through the opening that is sealed or sealable by means of the sealing element (and through the entry plane) for connection with the first connector element. The first connector element can be at least partially provided and / or the second connector element can be fully provided within the volume enclosed by the housing.
[0147] Particularly when the first and second connector elements are assembled, a connection area exists between them within the volume enclosed by the housing. This connection area may, for example, include a mating surface that can be part of either the first or the second connector element.
[0148] In one embodiment, it is provided that at least one electrical conductor extends through the sealing element.
[0149] In one embodiment, it is provided that the housing is at least partially slid or can be slid onto the first connector element, in particular forming a force-fit connection between the housing and the first connector element, and / or wherein the first connector element can be mechanically coupled to a printed circuit board by forming at least one electrically conductive connection between the first connector element and the printed circuit board, in particular by means of a soldered connection, a screw connection and / or an adhesive connection.
[0150] In one embodiment, it is provided that after the sealing element has been inserted into the housing, the housing is sealed against the ingress of splashing water by means of the sealing element, which is arranged in particular in the entry plane, in particular by means of a positive locking mechanism.
[0151] According to a fourth aspect, the invention relates to an electronic module comprising a printed circuit board and an electrical connector according to the third aspect of the invention, wherein the first connector element of the electrical connector is mechanically coupled to the printed circuit board by forming at least one electrically conductive connection between the first connector element and the printed circuit board, in particular by means of a soldered connection, a screw connection and / or an adhesive connection. In this way, an electronic module can be provided with the advantages described above with regard to the electrical connector according to the third aspect of the invention.
[0152] The features described in relation to the electrical connector according to the third aspect of the invention can also be provided accordingly in the electronic module, individually and in any combination, unless otherwise indicated by the context.
[0153] In particular, the physical and functional configurations of the individual parts described in connection with the electrical connector according to the third aspect of the invention, as well as the described structural and functional relationships between the individual parts, can also be provided accordingly in the electronic module, individually and in any combination, unless otherwise indicated by the context.
[0154] Further features and aspects of the invention will become apparent from the following figures, which illustrate specific embodiments of the invention. The illustrated embodiments are exemplary. It is understood that there are a number of other different ways to implement the invention. The figures show:

[0159] Fig. 12 shows a schematic perspective partial section view of the electrical connector of the electronic module from Fig. 8 from one side, in which the housing and a sealing element arranged therein are shown in partial section, and
[0160] Fig. 13 shows a schematic perspective, cutaway view of parts of the electrical connector of the electronic module from Fig. 8 from a top oblique angle. Fig. 8 shows a schematic perspective view of an electronic module 81 according to the fourth aspect of the invention.
[0161] The electronic module 81 comprises a printed circuit board 83 and an electrical connector 85 according to the third aspect of the invention.
[0162] Fig. 9 shows a schematic perspective exploded view of parts of the electronic module 81. The chosen representation makes components of the electrical connector 85 particularly easy to see. To simplify the illustration, some elements of the electronic module 81 have been omitted.
[0163] The electrical connector 85 comprises a first connector element 87 and a second connector element 89. The first connector element 87 is mechanically attached to the circuit board 83 and electrically connected to it. The electrical connector 85 also comprises a housing 811. An entry plane 8E (shown as a dashed line) is defined for the housing 811.
[0164] The first connector element 87 is at least partially arranged or can be arranged within the housing 811 (Fig. 8). In the connected state of the first and second connector elements 87 and 89 shown in Fig. 8, the second connector element 89 is also arranged within the housing 811. The second connector element 89 is electrically connected to several electrical conductors 813. In the connected state, the electrical conductors 813 enter the housing 811 through the entry plane 8E.
[0165] A sealing element 815 is inserted or can be inserted into the housing 811 to seal an opening 817 of the housing 811 against the ingress of splashing water. The sealing element 815 can be inserted into the housing 811 along a direction of movement B. The opening 817 is located within the entry plane 8E and is bounded by an edge 819 of the housing 811. The opening 817 has no thickness, i.e., no extension along the direction of movement B. The sealing element 815 is located or can be located in the entry plane E. In the connected state of the first and second connector elements 87 and 89 shown in Fig. 8, the electrical conductors 813 extend through the sealing element 815.The first connector element 87 is at least partially arranged within the housing 811, in particular by sliding the housing 811, at least section by section, onto the first connector element 87, especially by forming a force-fit connection between the housing 811 and the first connector element 87. The first connector element 87 can project at least partially into the interior of the housing 811 through a further opening 821 in the housing 811. The further opening 821 is spaced apart from the opening 817 and can be potted or pottable with a potting compound 823 (illustrated only in Fig. 11) and thus be or can be sealed fluid-tight.
[0166] The sealing element 815 has three sealing lips: a first sealing lip 825a, a second sealing lip 825b, and a third sealing lip 825c. The three sealing lips 825a-825c are spaced apart from each other in the direction of movement B on a base body 827 of the sealing element 815 and surround the base body 827 completely.
[0167] A press fit can exist between the housing 811 and the sealing element 815. For this purpose, the outer width of the sealing element 815, for example in the area of the second sealing lip 825b, is advantageously larger than the inner width of a region of the housing 811, wherein, after the sealing element 815 has been inserted into the housing 811, an outer surface of the second sealing lip 825b is in contact with an inner surface of the region of the housing 811.
[0168] After the insertion and / or at least temporarily during the insertion of the sealing element 815 into the housing 811, the second and third sealing lips 825b and 825c are in frictional contact with the housing 811, in particular with an inner surface 829 (see Fig.
[0169] 10) of housing 811, on.
[0170] Fig. 10 shows a schematic perspective view of the housing 811.
[0171] The housing 811 has a projection 831 on its inner surface 829, which at least partially limits the volume enclosed by the housing 811. The projection 831 extends from the surface 829 and is integrally formed with the housing 811. The projection serves to deform the sealing element 815.
[0172] An end 833 of the projection 831 facing the opening 817 of the housing 811 is spaced apart from the opening 817 and thus also from the entry plane 8E. This allows the sealing element 815 to be reliably positioned in an initial position in an entry area 835 of the housing 811 and then inserted into the housing 811 along the direction of movement B. An end section 837 of the projection 831 facing the opening 817 of the housing 811 has a curved surface area. This facilitates the insertion of the sealing element 815 into the housing 811.
[0173] Fig. 11 shows a schematic cross-sectional view of the electronic module 81 in a cross-sectional plane. The potting compound 823 is also illustrated by several dashed lines. Fig. 12 shows a schematic perspective, partially cutaway view of the electrical connector 85 from one side. The housing 811 (including the integrally formed projection 831) is shown in partial section, and the sealing element 815 arranged in the housing 811 is shown in section, which is illustrated by hatching in Fig. 12. The first connector element 87 is also hidden.
[0174] After and / or at least temporarily during the insertion of the sealing element 815 into the housing 811, the second and third sealing lips 825b and 825c are deformed, or deformable, at least in certain areas by the projection 831. In Fig. 11, the sealing lips 825b and 825c on the right side are in contact with the housing 811 and are thus deformed. On the left side, the sealing lips 825b and 825c are more deformed due to the projection 831. In the illustration shown in Fig. 12, with a sectioned view of the housing 811 and the sealing element 815, the deformation of the second and third sealing lips 825b and 825c of the sealing element 815 in the area of the projection 831 is illustrated. This clearly shows the effect of the projection 831 on the sealing element 815. A deformation, in particular of the sealing lips 825b and 825c in the left and right areas, due to the interaction with the housing 811 is not shown in Fig. 12.
[0175] The deformation of the sealing element 815, and especially its second and third sealing lips 825b and 825c, is particularly well achieved by the fact that the projection 831 has a principal direction of extension that runs perpendicular to the inlet plane 8E, and thus parallel to the direction of movement B. The deformation or deformability is such that, after insertion and / or at least temporarily during insertion of the sealing element 815 into the housing 811, air from the volume enclosed by the housing 811 can escape into the environment of the housing 811.
[0176] Fig. 13 shows a schematic perspective, cutaway view of the housing 811 with the sealing element 815 inserted therein, in the state shown in Figs. 8 and 11, from an oblique angle above. The sectioning plane QE runs parallel to the inlet plane 8E, but offset in the direction of movement B, and intersects the projection 831. The section thus passes through a portion of the projection 831 located beyond the end section 837 facing the opening 817 of the housing 811 in the direction of movement B.
[0177] In the cross-sectional plane QE, the projection 831 has an outer contour that is at least partially rectangular. As a result, the second and third sealing lips 825b and 825c do not completely seal around the projection 831. Instead, a gap forms between the projection 831 and the sealing element 815 (in particular, its second and third sealing lips 825b and 825c). This allows, in particular, for at least partial pressure equalization between a volume enclosed by the housing 811 and the surrounding environment after and / or at least temporarily during the insertion of the sealing element 815 into the housing 811.
[0178] After the sealing element 815 is inserted into the housing 811, the first sealing lip 825a is arranged in the inlet plane 8E and / or rests against the edge 819 of the housing 811 (Fig. 11, Fig. 12). This allows the opening 817 of the housing 811 to be sealed against the ingress of splash water. At the same time, the first sealing lip 825a, together with the housing 811, in particular the edge 819 of the housing 811, forms a valve in the form of a check valve. This allows air to escape from the volume enclosed by the housing 811 (e.g., via the opening 817) into the surrounding environment of the housing 811.
[0179] As noted above, when the sealing element 815 is inserted into the housing 811, air can escape, at least partially, from the volume enclosed by the housing 811 into the surroundings of the housing 811 during and / or after the insertion of the sealing element 815 into the housing 811 by means of deformation of the sealing element 815 by the projection. For example, the air can escape substantially against the direction of movement B and / or via the opening 817.
[0180] After the sealing element 815 has been inserted into the housing 811, the housing 811 is sealed against the ingress of splash water through the opening 817 by means of the sealing element 815 arranged in the entry plane 8E.
[0181] An electronic module according to the fourth aspect of the invention, such as the electronic module 81 described above with reference to Figures 8-13, can be manufactured simply yet reliably. For example, the following manufacturing method can be used:
[0182] A first connector element is mechanically and / or electrically coupled to a conductor plate, for example by means of a soldered connection.
[0183] A housing is slid onto the first connector element.
[0184] The circuit board, the first connector element, and the housing are at least partially potted together in a potting compound. This process seals an opening in the housing that is located away from an entry point.
[0185] A second connector element, connected to electrical wires, is inserted into the housing and an electrically conductive connection is established between the two connector elements.
[0186] A sealing element seals the entrance level of the housing. The electrical conductors extend through this sealing element.
