Abstract
Description
[0001] The invention relates to an electronic device according to claim 1.
[0002] The technical problem of inadequate connections between heating wires and power sources in radomes, which typically arise from embedding plugs / sockets into the plastic, is well known in the art. The plugs / sockets are typically injected into the plastic of the radomes. This creates a one-piece, rigid connection. However, this connection is highly susceptible to vibrations and temperature fluctuations because the plug material and the radome material behave differently.
[0003] DE 10 2014 203 301 A1 discloses an electronic device comprising a printed circuit board (PCB) on which a socket is provided, by means of which an electrical connection can be established with a corresponding connector. The socket is arranged on one side of the PCB, and elastic elements are also provided to compensate for mechanical stresses such as vibrations or thermal stresses.
[0004] US 2022 / 0 322 541 A1 discloses an electronic control device with a circuit board in a housing, consisting of a lower housing part (base) and an upper housing part (case).
[0005] The object of the invention is to provide an electronic device with a socket for a plug connection, by means of which vibrations and temperature fluctuations can be better withstood.
[0006] This object is achieved according to the invention by an electronic device having the features of patent claim 1. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.
[0007] One aspect of the invention relates to an electronic device, in particular a radome, comprising a housing and a socket for electronically coupling the electronics within the housing to an external component. The socket is attached to a circuit board, which in turn is attached to the housing by means of at least one retaining element. In contrast to conventional methods, in which the sockets are usually injected directly into the plastic, creating a rigid connection, applying the socket to the circuit board and possibly resiliently connecting the circuit board to the housing enables a more flexible connection. This means that neither temperature fluctuations nor vibrations can have a detrimental effect on the plug connection, since the materials behave differently.
[0008] Furthermore, the invention provides for at least one spring element to be arranged between the circuit board and the housing, resiliently spacing the circuit board relative to the housing. Thus, the spring element is arranged between the circuit board and the housing and resiliently supports the circuit board relative to the housing. This particularly preferred embodiment enables continuous positioning of the circuit board at a predetermined location, which is determined by the holding elements and the springing of the spring element. While this allows for movement options, these are compensated for by the spring force, resulting in a stable yet flexible fastening that also dampens vibrations and better withstands temperature fluctuations.
[0009] Likewise, the invention provides for the circuit board to have the socket on a first side and at least one spring element on the opposite second side, with the socket and the spring element being arranged in the same area of the circuit board. This symmetrical design achieves, in particular, a uniform distribution of forces, thereby enabling a stable and, in particular, balanced fastening.
[0010] In an advantageous embodiment of the invention, the circuit board has at least one through-opening through which the at least one retaining element for holding the circuit board can be passed. This arrangement enables a simple insertion option that is easy to handle and enables particularly uncomplicated fastening.
[0011] In another advantageous embodiment of the invention, it is provided that the at least one retaining element is elongated and oriented transversely to a surface area on the housing in which the retaining element is arranged. This enables relative movement between the circuit board and the housing, which also provides corresponding flexibility and adaptability to compensate for or dampen any thermal expansion or mechanical stress or vibration.
[0012] In another advantageous embodiment of the invention, the retaining element is provided in one piece with the housing and / or has a barb-shaped head. This allows, for example, for easy insertion while simultaneously providing an improved retaining function, since the barb-shaped head prevents accidental detachment of the circuit board with the socket.
[0013] In another advantageous embodiment of the invention, the retaining element is at least partially elastic. This not only enables the aforementioned advantages, but also absorbs and / or compensates for vibrations and thermal expansion during operation.
[0014] In another advantageous embodiment of the invention, the circuit board is resiliently held against a barb-shaped head of the at least one retaining element by means of the at least one spring element. This embodiment enables secure and flexible fastening of the circuit board, with the spring force of the spring element pressing the circuit board against the barb-shaped head, thus ensuring a more reliable connection.
[0015] In another advantageous embodiment of the invention, it is provided that the at least one spring element is supported on the one hand against the circuit board and on the other hand against a region of the electronic device within the housing. As a result, the spring element is positioned within the housing and is supported on the one hand against the circuit board and on the other hand against an internal region of the electronic device, thus enabling reliable springing and support away from influences affecting the housing.
[0016] In another advantageous embodiment of the invention, the cabling from the socket to the electronics runs along the spring element into the area of the electronic device within the housing. This design enables orderly routing of the cabling and more efficient use of the available space in the housing. By integrating the cabling along the spring element, for example, the structure is kept compact and a particularly trouble-free connection between the socket and the electronic device is provided.
[0017] Further features of the invention emerge from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective specified combination, but also in other combinations or on their own.
[0018] The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings. They show: Fig. 1 is a schematic perspective view of a possible embodiment of an electronic device with a housing and a socket; and Fig. 2 is a sectional view of the electronic device 10 to illustrate the possible arrangement of the components.
[0019] In the figures, identical and functionally identical elements are provided with the same reference numerals.
[0020] Fig. 1 shows a possible embodiment of an electronic device 10 with a housing 12 and a socket 14 for electronic coupling with non-visible electronics 11 within the housing 12 with an external component (not shown). The socket 14 is thus part of a plug connection that can be used for the electronic coupling of the electronic device 10. It is attached to an elongated, flat circuit board 16, which in turn is attached to the housing 12 by means of at least one holding element 18. The housing 12 has a surface area 12a that corresponds to the geometry of the circuit board 16, so that the circuit board 16 can rest against or be arranged on the housing 12 without any restrictions on movement. The circuit board 16 has at least one through-opening 20, which is provided for a corresponding holding element 18 and allows it to be guided through. Fig. 1 shows two through-openings 20 which are designed for respective holding elements 18.
[0021] The circuit board 16 is elongated, meaning it has an elongated shape. The through-holes 20 are positioned accordingly at the respective ends of the circuit board 16 to provide a more stable attachment. This enables an even distribution of holding forces and contributes to increased stability of the connection between the circuit board 16 and the housing 12.
[0022] The holding elements 18 are elongated and are aligned transversely to the surface area 12a on the housing 12. They are not only elongated (y-direction) but also wide, with the width of one holding element 18 oriented vertically (z-direction) and the other horizontally (x-direction). Corresponding through-openings 20 are thereby positioned on the circuit board 16 to enable corresponding attachment to the holding elements 18. This design enables relative displacement of the circuit board 16 with the socket 14 relative to the housing 12, in particular along the elongated alignment of the holding elements 18 in the x-direction. However, it should be noted that the holding elements 18 can also have alternative geometries, and the through-openings 20 can be configured accordingly.
[0023] The retaining elements 18 can also be formed in one piece with the housing 12, making them integral components of the housing 12, meaning that the retaining elements 18 are already attached or manufactured during the manufacture of the housing 12. The retaining elements 18 can have a barb-shaped head 18a that enables the circuit board 16 to be inserted and prevents accidental detachment. In addition to the barb-shaped design, the head 18a can also be wider and partially flexible in order to force the circuit board 16 over it and to guide the heads 18a through the through-openings 20. Alternatively, the through-openings 20 themselves can be partially flexible on the inner circumference to allow hard heads 18a of the retaining elements 18 to pass through.
[0024] The retaining element 18 can be partially elastic or made of an elastic material, which not only simplifies attachment but also absorbs or at least partially dampens vibrations in the area between the socket 14 and the electronic device 10. For example, the retaining element 18 can be made of rubber and bonded to the housing 12 or connected in another way, for example by vulcanization.
[0025] It is particularly preferred to arrange at least one spring element 22 between the circuit board 16 and the housing 12, which spring element 22 supports the circuit board 16 relative to the housing. As in Fig. As shown in Figure 1, two spring elements 22 can be used to provide two resilient support points and to particularly effectively hold and dampen the elongated circuit board 16. The spring elements 22 are particularly designed as resilient strips that press the circuit board 16 against the barb-shaped heads 18a of the holding elements 18.
[0026] Thus, the circuit board 16 is resiliently held by at least one spring element 22 against a barb-shaped head 18a of the retaining element 18. This arrangement thus enables a particularly secure yet flexible attachment of the circuit board 16 and thus the socket 14 to the housing 12, effectively dampening unwanted movements or vibrations between the socket 14 and the electronic device 10. The resilient mounting exerts uniform pressure on the circuit board 16 while simultaneously allowing a certain degree of flexibility to compensate for loads and movements.
[0027] It is also possible for the circuit board 16 to have the socket 14 on one side 16a and at least one spring element 22 on the opposite side 16b, wherein the socket 14 and the spring element 22 are located in the same area 17 of the circuit board 16. This design therefore enables at least partially symmetrical springing and stabilization of the circuit board 16 on the housing 12. By arranging the socket 14 on one side 16a of the circuit board 16 and the spring elements 22 on the opposite side 16b, a uniform distribution of the spring force is achieved. This not only presses the circuit board 16 against the particularly barb-shaped head 18a of the holding element 18, but also provides additional stability along the entire circuit board 16. This symmetrical arrangement results in the loads on the electronic device 10 being evenly distributed.
[0028] Fig.Figure 2 shows a sectional view of the electronic device 10 to illustrate the possible arrangement of the components. The at least one spring element 22 rests on the one hand against the circuit board 16 and on the other hand against a region 24 of the electronic device 10 within the housing 12. It is also possible for a wiring 26 of the socket 14 to run along the spring element 22 toward the region 24 of the electronic device 10 within the housing 12. The wiring 26 of the socket 14, which runs along the spring element 22 and leads to the region 24 of the electronics, thus enables an orderly and targeted routing of the electrical connections. This not only contributes to the efficiency of the electronic device but also minimizes possible interference and disturbances.
[0029] The support of the spring element 22 against the circuit board 16 and the area 24 of the electronic device 10 within the housing 12 enables stable yet flexible positioning of the circuit board 16 and thus the socket 14. This ensures that the socket 14 is firmly connected to the electronic device 10 while simultaneously dampening potential vibrations and shocks. This arrangement not only enables effective suspension of the circuit board 16 but also an orderly connection of the electrical components within the electronic device 10, which contributes to improved functionality and performance.
[0030] Overall, this arrangement enables a robust and reliable electrical connection within the electronic device 10, thereby improving performance, for example. In summary, the invention proposes a spring-loaded connection of a plug to an electrical load.
