[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-2 The present invention describes a housing 100 for mounting a circuit board 200 according to an embodiment of the present invention. The housing 100 can be mounted on an electronic device 1.

[0022] According to the first aspect of the present invention, a housing 100 for mounting a circuit board 200, such as Figure 1 and Figure 2 As shown, the housing 100 for mounting the circuit board 200 may include: a mounting housing wall 10 and a first elastic structure 50. A limiting wall 20 is fixed on the inner surface of the mounting housing wall 10. The limiting wall 20 and the mounting housing wall 10 together define a mounting space 30 for mounting the circuit board 200. Along the arrangement direction of the mounting housing wall 10 and the limiting wall 20, the end of the mounting space 30 away from the mounting housing wall 10 is open to form an assembly opening. The limiting wall 20 has a first wall portion 21 and a second wall portion 22. Along a first direction, the first wall portion 21 and the second wall portion 22... Located on opposite sides of the mounting space 30, the first wall portion 21 is fixed with a limiting block 40 at the end away from the mounting shell wall 10. Along the first direction, at least a portion of the limiting block 40 is located on the side of the first wall portion 21 facing the second wall portion 22. The first elastic structure 50 is provided on the second wall portion 22 and can deform along the first direction. The first elastic structure 50 is used to limit and cooperate with the circuit board 200 to limit the circuit board 200 within the mounting space 30. The mounting shell wall 10 and the limiting wall 20 are arranged in the second direction, and the first direction and the second direction are perpendicular.

[0023] It should be noted that electronic devices contain circuit boards. The electronic device functions normally when the headers and sockets on the circuit board mate with the headers and sockets on another circuit board within the device. Existing circuit boards can be fixed to the casing or other components of the electronic device. However, there may be tolerances when the headers and sockets are mounted on their respective circuit boards, causing some deviation during assembly. This prevents proper alignment of the headers and sockets, affecting their proper use.

[0024] Based on this, this application provides a housing 100 for mounting a circuit board 200. A limiting wall 20 can be fixedly provided on the inner surface of the mounting housing wall 10. The limiting wall 20 can be bonded to the mounting housing wall 10 and can be integrally formed with the mounting housing wall 10. The limiting wall 20 can be located on the side of the mounting housing wall 10 facing the interior of the housing 100, and the limiting wall 20 can be perpendicular to the inner surface of the mounting housing wall 10. The mounting housing wall 10 can serve to fix and support the limiting wall 20. The limiting wall 20 and the mounting housing wall 10 can jointly define a mounting space 30, within which the circuit board 200 can be mounted. Along the arrangement direction of the mounting housing wall 10 and the limiting wall 20, the end of the mounting space 30 facing away from the mounting housing wall 10 can be open, and an assembly port can be formed at the end of the mounting space 30 facing away from the mounting housing wall 10. The circuit board 200 can enter the mounting space 30 through the assembly port and be mounted within the mounting space 30. When the housing 100 is as described above... Figure 1 When setting the orientation, the mounting shell wall 10 and the limiting wall 20 are arranged in the following directions: Figure 1 The Z-direction in the middle.

[0025] The limiting wall 20 may have a first wall portion 21 and a second wall portion 22. The first wall portion 21 and the second wall portion 22 may be located on both sides of the mounting space 30 along a first direction, and the first wall portion 21 and the second wall portion 22 may be spaced apart along the first direction. The circuit board 200 may be disposed between the first wall portion 21 and the second wall portion 22. When the housing 100 is as follows... Figure 1 When setting the direction, the first direction is Figure 1 In the Y-direction, the arrangement direction of the mounting shell wall 10 and the limiting wall 20 can be a second direction, and the first direction can be perpendicular to the second direction. Along the second direction, a limiting block 40 can be provided at the end of the first wall portion 21 facing away from the mounting shell wall 10. The limiting block 40 can be bonded to the first wall portion 21 and can be integrally formed with the first wall portion 21. Along the first direction, at least a portion of the limiting block 40 can be located on the side of the first wall portion 21 facing the second wall portion 22. That is, when the circuit board 200 is installed in the mounting space 30, at least a portion of the limiting block 40 can be arranged opposite to the circuit board 200 along the second direction. The limiting block 40 can limit the circuit board 200, so that the circuit board 200 can be snapped into the shell 100, which helps to reduce the probability of the circuit board 200 falling off through the assembly port and improves the reliability of the circuit board 200 installation.

[0026] A first elastic structure 50 may be provided on the second wall portion 22. The first elastic structure 50 can deform along a first direction. When the circuit board 200 is installed in the mounting space 30, the first elastic structure 50 can engage with the circuit board 200 and abut against it, confining the circuit board 200 within the mounting space 30. When the circuit board 200 wants to move towards the first elastic structure 50 along the first direction, the first elastic structure 50 can deform, allowing the circuit board 200 to move smoothly along the first direction. When the circuit board 200 is installed in the mounting space 30, it can be assembled between the first wall portion 21 and the second wall portion 22. The limiting block 40 can be located on the side of the circuit board 200 facing away from the mounting shell wall 10 along the second direction. At this time, the circuit board 200 can abut against the first elastic structure 50, and the first elastic structure 50 can cooperate with the limiting block 40 to limit the circuit board 200 within the installation space 30. The circuit board 200 can be spaced apart from the first wall portion 21 and the second wall portion 22, thereby providing movement space for the circuit board 200 to move in the first direction, so that the circuit board 200 can move in the first direction.

[0027] The circuit board 200 may have header nuts 210 or header pins. The header nuts 210 can be assembled with header pins on other circuit boards 200. When the header pins and header nuts 210 are plugged in, if the header pins and header nuts 210 are positioned opposite each other along a second direction, the header pins and header nuts 210 can be aligned and assembled smoothly. Alternatively, when the header pins and header nuts 210 are plugged in, there may be tolerances when the header pins and header nuts 210 mate with the corresponding circuit board 200. Part of the structure of the header nut 210 may be misaligned with the corresponding header pin along a first direction, and the header pins and header nuts 210 cannot be aligned well. If a portion of the structure of the nut 210 is located on the side of the corresponding pin facing the second wall 22 along the first direction, a pushing force can be applied to the nut 210 to make it move towards the first wall 21 along the first direction. The nut 210 can drive the corresponding circuit board 200 to move together along the first direction, so that the nut 210 and the pin can be set opposite to each other along the second direction, so that the nut 210 and the corresponding pin can be smoothly plugged in and connected.

[0028] If a portion of the structure of the nut 210 is located on the side of the pin facing the first wall 21 along the first direction, a pushing force can be applied to the nut 210 to move it towards the second wall 22 along the first direction. The nut 210 can drive the circuit board 200 to move together along the first direction. Since the first elastic structure 50 is in a limiting fit with the circuit board 200, when the circuit board 200 moves towards the second wall 22 along the first direction, the circuit board 200 can apply pressure to the first elastic structure 50, and the first elastic structure 50 can undergo elastic deformation, so that the nut 210 and the pin can be arranged opposite to each other along the second direction, so that the nut 210 and the corresponding pin can be smoothly plugged in and connected. This helps to reduce the probability of the nut 210 and the corresponding pin squeezing each other along the first direction, reduces the probability of there being an interaction force between the nut 210 and the corresponding pin along the first direction, reduces the probability of the nut 210 and the corresponding pin falling off due to long-term mutual squeezing, and improves the reliability of the circuit board 200.

[0029] In this embodiment of the application, by setting the first elastic structure 50, the circuit board 200 can move smoothly when subjected to a force along the first direction, which can reduce the probability of the pin header 210 and the corresponding pin header on the circuit board 200 pressing against each other along the first direction. This is beneficial to reducing the probability of there being an interaction force between the pin header and the pin header 210 along the first direction, reducing the probability of the pin header and the pin header 210 falling off due to long-term mutual pressing, and improving the reliability of the circuit board 200.

[0030] In some embodiments of this utility model, such as Figure 2 As shown, along the second direction, the end of the first elastic structure 50 facing away from the mounting shell wall 10 is fixedly connected to the second wall portion 22.

[0031] The end of the first elastic structure 50 facing away from the mounting shell wall 10 along the second direction can be connected to the second wall portion 22. The first elastic structure 50 can be bonded to the second wall portion 22, and the first elastic structure 50 can be integrally formed with the second wall portion 22. The second wall portion 22 can serve to fix and support the first elastic structure 50, which helps to reduce the probability of the first elastic structure 50 falling off when it is compressed, and helps to improve the reliability of the first elastic structure 50, so that the circuit board 200 can move smoothly along the first direction.

[0032] In some embodiments of this utility model, such as Figure 2 As shown, the second wall portion 22 has a first mounting opening 221, which extends through the second wall portion 22 in a first direction, and at least a portion of the first elastic structure 50 is located within the first mounting opening 221.

[0033] The second wall portion 22 may have a first mounting opening 221, which extends through the second wall portion 22 in a first direction and communicates with the mounting space 30. At least a portion of the first elastic structure 50 may be located within the first mounting opening 221, meaning a part of the first elastic structure 50 may be located within the first mounting opening 221, and another part of the first elastic structure 50 may be located within the mounting space 30, or all of the first elastic structure 50 may be located within the first mounting opening 221. This embodiment of the application uses the example of a part of the first elastic structure 50 being located within the first mounting opening 221 and another part of the first elastic structure 50 being located within the mounting space 30 for illustration. When the circuit board 200 moves toward the first elastic structure 50 along the first direction, the circuit board 200 can abut against the first elastic structure 50, and the circuit board 200 deforms the first elastic structure 50. The first mounting port 221 can provide deformation space for the deformation of the first elastic structure 50, which is conducive to further enabling the circuit board 200 to move smoothly along the first direction, further improving the reliability of the first elastic structure 50, further enabling the pin header 210 and pin header to be smoothly connected, further reducing the probability of the pin header and pin header 210 falling off due to long-term mutual compression, and further improving the reliability of the circuit board 200.

[0034] In some embodiments of this utility model, such as Figure 2 As shown, the first elastic structure 50 may include: a first elastic body 51 and a first limiting boss 52. The end of the first elastic body 51 facing away from the mounting shell wall 10 is fixedly connected to the second wall portion 22. The first limiting boss 52 is fixedly provided on the surface of the first elastic body 51 facing the mounting space 30. Along the second direction, the first limiting boss 52 is located between the two ends of the first elastic body 51. The end face of the first limiting boss 52 facing the mounting shell wall 10 is used to contact and limit the circuit board 200.

[0035] The end of the first elastic body 51 facing away from the mounting shell wall 10 along the second direction is fixedly connected to the second wall portion 22. The first elastic body 51 can be bonded to the second wall portion 22, and the first elastic body 51 can be integrally formed with the second wall portion 22. The first elastic body 51 and the first limiting boss 52 can be arranged along the first direction. The first limiting boss 52 can be fixed on the surface of the first elastic body 51 facing the mounting space 30, and the first limiting boss 52 can be integrally formed with the first elastic body 51. As an example, the first elastic body 51 can be located inside the first mounting opening 221, and the first limiting boss 52 can be located inside the mounting space 30, thereby achieving the effect that part of the structure of the first elastic structure 50 is located inside the first mounting opening 221.

[0036] Along the second direction, the first limiting boss 52 can be located between the two ends of the first elastic body 51. When the circuit board 200 is installed in the mounting space 30, the end of the first elastic body 51 near the mounting shell wall 10 along the second direction can be correspondingly positioned with the circuit board 200 along the first direction. When the circuit board 200 moves towards the first elastic structure 50 along the first direction, the circuit board 200 abuts against the end of the first elastic body 51 near the mounting shell wall 10 along the second direction. The circuit board 200 applies pressure to the end of the first elastic body 51 near the mounting shell wall 10 along the second direction, thereby deforming the first elastic body 51. The end face of the first limiting boss 52 facing the mounting shell wall 10 along the second direction can contact and limit the circuit board 200. That is, the first limiting boss 52 can cooperate with the limiting block 40 to limit the circuit board 200 within the mounting space 30, which helps to further reduce the probability of the circuit board 200 falling off the assembly port, further improves the reliability of the circuit board 200 installation, and improves the reliability of the shell 100.

[0037] In some embodiments of this utility model, such as Figure 2 As shown, the end face of the first limiting boss 52 facing away from the mounting shell wall 10 is constructed as a guide slope 521. From the limiting wall 20 to the mounting shell wall 10, the guide slope 521 is inclined inward into the mounting space 30.

[0038] Along the second direction, the end face of the first limiting boss 52 facing away from the mounting housing wall 10 can be constructed as a guide slope 521. When the circuit board 200 is installed in the mounting space 30 through the assembly port, the guide slope 521 can play a guiding role. From the limiting wall 20 to the mounting housing wall 10, the guide slope 521 can be inclined inward into the mounting space 30. That is, one end of the guide slope 521 connected to the first elastic body 51 is located on the side of the first limiting boss 52 facing away from the mounting housing wall 10 along the second direction, and the other end of the guide slope 521 away from the first elastic body 51 along the first direction is located on the side of the first limiting boss 52 close to the mounting housing wall 10 along the second direction. When the circuit board 200 is installed in the mounting space 30 through the assembly port, after the circuit board 200 contacts the guide ramp 521, it will slide into the mounting space 30 along the inclined direction of the guide ramp 521. This facilitates the installation of the circuit board 200 and reduces the installation difficulty of the circuit board 200. In addition, the guide ramp 521 can also reduce the probability of direct rigid collision between the circuit board 200 and the first limiting boss 52 when the circuit board 200 is installed in the mounting space 30. This helps to disperse stress, reduce the risk of damage to the circuit board 200 and the first limiting boss 52, and extend the service life of the circuit board 200 and the first limiting boss 52.

[0039] In some embodiments of this utility model, such as Figure 2As shown, there are multiple first elastic structures 50, and the multiple first elastic structures 50 are arranged sequentially along a third direction, with the first direction, the second direction and the third direction being perpendicular to each other.

[0040] There can be multiple first elastic structures 50, and these multiple first elastic structures 50 can be arranged sequentially along a third direction. The distance between any two adjacent first elastic structures 50 can be equal. When the shell 100 is as follows... Figure 1 When setting the direction, the third direction is... Figure 1 In the X direction, the first direction, the second direction, and the third direction are perpendicular to each other. By setting multiple first elastic structures 50, it is beneficial to reduce the force exerted by the circuit board 200 on each first elastic structure 50, which is beneficial to further extend the service life of the first elastic structure 50 and the service life of the housing 100.

[0041] In some embodiments of this utility model, such as Figure 2 As shown, the housing 100 may further include: a second elastic structure 60, and the limiting wall 20 further having two third wall portions 23 along a third direction. The two third wall portions 23 are respectively located on opposite sides of the mounting space 30. At least one of the two third wall portions 23 is provided with the second elastic structure 60. The second elastic structure 60 is deformable along a third direction. The surface of the second elastic structure 60 facing the mounting space 30 is used to contact and limit the circuit board 200. The first direction, the second direction and the third direction are perpendicular to each other.

[0042] The limiting wall 20 also has two third wall portions 23, which are arranged opposite each other along a third direction. The two third wall portions 23 are located on opposite sides of the mounting space 30 along the third direction and are spaced apart. At least one of the two third wall portions 23 is provided with a second elastic structure 60. One or both third wall portions 23 may be provided with the second elastic structure 60. This embodiment uses the example of both third wall portions 23 being provided with the second elastic structure 60 for illustration. The second elastic structure 60 can deform along a third direction. When the circuit board 200 is installed in the mounting space 30, the surface of the second elastic structure 60 facing the mounting space 30 can contact and limit the circuit board 200, and the second elastic structure 60 can abut against the circuit board 200. When the circuit board 200 wants to move towards the second elastic structure 60 along a third direction, the second elastic structure 60 can deform, allowing the circuit board 200 to move smoothly along the third direction.

[0043] When the pin header and the nut header 210 are plugged in, there are tolerances between the pin header and the nut header 210 when they are mated with the corresponding circuit board 200. Part of the structure of the nut header 210 may be misaligned with the corresponding pin header in a third direction, and the pin header and the nut header 210 cannot be properly aligned. If a portion of the structure of the nut 210 is located on the side of the corresponding pin facing one of the third wall portions 23 along the third direction, a pushing force can be applied to the nut 210 to move it towards the other third wall portion 23 along the third direction. The nut 210 can drive the circuit board 200 to move together along the third direction. The circuit board 200 can contact the second elastic structure 60 and apply pressure to the second elastic structure 60. The second elastic structure 60 can undergo elastic deformation, thereby allowing the nut 210 and the corresponding pin to be positioned opposite each other along the second direction. This allows the nut 210 and the pin to be smoothly connected, which helps reduce the probability of the pin and nut 210 squeezing each other along the third direction, reduces the probability of interaction forces between the pin and nut 210 along the third direction, further reduces the probability of the pin and nut 210 falling off due to long-term squeezing, and further improves the reliability of the circuit board 200.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, along the second direction, the end of the second elastic structure 60 facing away from the mounting shell wall 10 is fixedly connected to the corresponding third wall portion 23.

[0045] The end of the second elastic structure 60 facing away from the mounting shell wall 10 along the second direction can be connected to the corresponding third wall portion 23. The second elastic structure 60 can be bonded to the corresponding third wall portion 23, and the second elastic structure 60 can be integrally formed with the corresponding third wall portion 23. The third wall portion 23 can serve to fix and support the corresponding second elastic structure 60, which helps to reduce the probability of the second elastic structure 60 falling off when it is squeezed, and helps to improve the reliability of the second elastic structure 60, so that the circuit board 200 can move smoothly along the third direction.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the second elastic structure 60 may include: a second elastic body 61 and a second limiting boss 62. The end of the second elastic body 61 facing away from the mounting shell wall 10 is fixedly connected to the corresponding third wall portion 23. The second limiting boss 62 is fixedly provided on the surface of the second elastic body 61 facing the mounting space 30. The surface of the second limiting boss 62 facing the mounting space 30 is used to contact and limit the circuit board 200.

[0047] The end of the second elastic body 61 facing away from the mounting shell wall 10 along the second direction can be fixedly connected to the corresponding third wall portion 23. The second elastic body 61 can be bonded to the corresponding third wall portion 23, and the second elastic body 61 can be integrally formed with the corresponding third wall portion 23. The second elastic body 61 and the second limiting boss 62 can be arranged along the third direction. The second limiting boss 62 can be fixedly provided on the surface of the second elastic body 61 facing the mounting space 30, and the second limiting boss 62 can be integrally formed with the second elastic body 61. Along the third direction, the second limiting boss 62 can be correspondingly provided with the circuit board 200 along the third direction, and the surface of the second limiting boss 62 facing the mounting space 30 can contact and limit the circuit board 200. As an example, the second limiting boss 62 can be provided at one end of the second elastic body 61 facing the mounting shell wall 10, and the end face of the second limiting boss 62 facing the mounting shell wall 10 can be coplanar with the end face of the second elastic body 61 facing the mounting shell wall 10.

[0048] When the circuit board 200 moves toward the second elastic structure 60 in a third direction, the circuit board 200 can contact the surface of the second limiting boss 62 facing the mounting space 30. The circuit board 200 can apply pressure to the second limiting boss 62. The force acting on the second limiting boss 62 can be further transmitted to the second elastic body 61. The second elastic body 61 can deform, which is beneficial to further facilitate the smooth insertion and connection of the pin header 210 and the pin header, further reduces the probability of the pin header and the pin header 210 squeezing each other in a third direction, further reduces the probability of there being an interaction force between the pin header and the pin header 210 in a third direction, further reduces the probability of the pin header and the pin header 210 falling off due to long-term mutual squeezing, and further improves the reliability of the circuit board 200.

[0049] In some embodiments of this utility model, such as Figure 2 As shown, the third wall portion 23 with the second elastic structure 60 has a second mounting opening 231, which penetrates the third wall portion 23 in a third direction, and at least a portion of the second elastic structure 60 is located within the second mounting opening 231.

[0050] The third wall portion 23 of the second elastic structure 60 may have a second mounting opening 231. The second mounting opening 231 can penetrate the corresponding third wall portion 23 in a third direction and can communicate with the mounting space 30. At least a portion of the second elastic structure 60 can be located within the second mounting opening 231, that is, a part of the structure of the second elastic structure 60 can be located within the second mounting opening 231, and another part of the structure of the second elastic structure 60 can be located within the mounting space 30, or the entire structure of the second elastic structure 60 can be located within the second mounting opening 231. This embodiment of the application is illustrated by taking the example where a part of the structure of the second elastic structure 60 is located within the second mounting opening 231, and another part of the structure of the second elastic structure 60 is located within the mounting space 30. When the circuit board 200 moves toward the second elastic structure 60 in a third direction, the circuit board 200 can abut against the second elastic structure 60, causing the second elastic structure 60 to deform. The second mounting port 231 provides deformation space for the deformation of the second elastic structure 60, which is beneficial for the circuit board 200 to move smoothly in a third direction, for improving the reliability of the second elastic structure 60, for enabling the pin header 210 and pin header to be smoothly connected, for reducing the probability of the pin header and pin header 210 falling off due to long-term mutual compression, and for further improving the reliability of the circuit board 200.

[0051] According to the second aspect of the present invention, the electronic device 1 may include a circuit board 200 and a housing 100. The housing 100 is the housing 100 for mounting the circuit board 200 in the above embodiment. The circuit board 200 is mounted in the mounting space 30, and at least one side wall of the circuit board 200 is spaced apart from the limiting wall 20. The limiting block 40 and the first elastic structure 50 can both be limited and cooperated with the circuit board 200.

[0052] Electronic device 1 may include circuit board 200 and housing 100 for mounting circuit board 200 as described in the above embodiments. Housing 100 forms mounting space 30, within which circuit board 200 can be mounted. At least one sidewall of circuit board 200 is spaced apart from limiting wall 20, allowing circuit board 200 to move within mounting space 30. By using housing 100 as described in the above embodiments, circuit board 200 can move within mounting space 30 along a first direction and a third direction, reducing the probability of mutual compression between pin headers 210 and corresponding pin headers on circuit board 200. This reduces the probability of interaction forces between pin headers 210 and corresponding pin headers, and reduces the probability of long-term mutual compression leading to detachment, thus improving the reliability of circuit board 200. Furthermore, limiting block 40 and first elastic structure 50 can both cooperate with circuit board 200 for limiting, and the limiting block 40 and first elastic structure 50 can jointly reduce the probability of circuit board 200 detaching from housing 100, further improving the reliability of housing 100.
