Description

Technical Field

[0001] This utility model relates to the field of PCB board mounting technology, and in particular to a PCB board mounting structure and electronic equipment. Background Technology

[0002] Traditional methods for fixing circuit boards include screw fixing, 3M adhesive fixing, spring clip fixing, snap-on fixing, and thermoforming. However, fixing circuit boards using self-tapping screws has the following drawbacks: drilling with self-tapping screws generates debris, which can lift the PCB board, resulting in a less tight assembly and poor reliability. Therefore, this technical defect in the PCB board installation process needs further improvement. Utility Model Content

[0003] Therefore, it is necessary to provide a PCB board mounting structure and electronic device to address the problem that the traditional use of self-tapping screws produces debris that lifts the PCB board, resulting in insufficient PCB board assembly.

[0004] A PCB board mounting structure includes: a housing assembly having a connection area; a PCB board disposed on the housing assembly having a first mounting hole; and a connector disposed on the PCB board and located at the first mounting hole, the connector passing through the first mounting hole and engaging with the connection area, the connector being movable relative to the housing assembly, the housing assembly, the PCB board, and the connector forming an accommodating space for accommodating debris generated when the connector moves relative to the housing assembly.

[0005] The first aspect of this application discloses a PCB board mounting structure. By designing a receiving space, debris generated by the housing assembly during the drilling process of the connector is contained within this space, preventing it from leaking out of the housing assembly and pushing up the PCB board. This design ensures a tight fit between the PCB board and the housing assembly, resulting in a more compact PCB board assembly and improving the assembly gap problem caused by debris in traditional methods. Furthermore, it eliminates the need for additional time to clean up the debris generated during drilling, offering good practicality. By forming a relatively enclosed space around the connector, debris from the first mounting hole and the connection area can be effectively contained within the receiving space, further preventing debris from pushing up the PCB board.

[0006] In one embodiment, the connection area includes a second mounting hole and a connection channel. The second mounting hole communicates with the connection channel. The connector passes through the first mounting hole and the connection channel sequentially and then mates with the second mounting hole. The portion of the connector located in the connection channel, the channel wall of the connection channel, and the PCB board enclose the receiving space. The connection channel provides clear guidance for the insertion and tightening of the connector. This design allows operators to more easily and accurately pass the connector through the first mounting hole and smoothly mate it with the second mounting hole along the connection channel. The PCB board installation is more secure, preventing the PCB board from shifting under external influences and affecting its performance.

[0007] In one embodiment, the cross-sectional area of ​​the connecting channel is greater than or equal to the cross-sectional area of ​​the second mounting hole. By making the cross-sectional area of ​​the connecting channel greater than or equal to the cross-sectional area of ​​the second mounting hole, a larger accommodating space is formed, providing more ample storage space for debris and preventing debris from accumulating and overflowing due to narrow space.

[0008] In one embodiment, the connection channel is located at the end of the second mounting hole. By positioning the connection channel at the end of the second mounting hole, i.e., adjacent to it, debris generated during operation within the second mounting hole is more concentrated in the relatively enclosed area of ​​the housing. This design prevents debris from scattering throughout the housing assembly, thus avoiding debris protruding from the PCB board and reducing the hassle of subsequent cleaning.

[0009] In one embodiment, at least a portion of the cross-sectional area of ​​the receiving space gradually increases in the direction toward the first mounting hole. By forming a funnel-shaped structure through this gradual increase in the cross-sectional area of ​​the receiving space, debris, once generated, moves along the direction of the gradually increasing cross-sectional area and is ultimately collected within the receiving space. This prevents debris from scattering randomly within the housing assembly and improves the debris collection efficiency.

[0010] In one embodiment, the housing assembly includes a housing member and an assembly post. The assembly post is disposed on the housing member and has the connection area. The assembly post, the PCB board, and the connector enclose the receiving space. The assembly post isolates the PCB board from the housing member, reducing the area of ​​direct contact between the PCB board and the housing member. This design prevents the housing member from being damaged by heat dissipation from the PCB board. Debris generated during connector drilling is primarily collected within the space enclosed by the assembly post, the PCB board, and the connector, ensuring the installation stability and electrical reliability of the PCB board.

[0011] In one embodiment, there are multiple connectors and multiple mounting posts, with the same number of connectors and mounting posts, and each connector and mounting post corresponding to a specific post. Through this one-to-one engagement of connectors and mounting posts, the PCB board can be fixed to the housing assembly at multiple points. Compared to fixing with a single connector, multi-point fixing can more evenly distribute the weight and external forces on the PCB board, preventing deformation, bending, or loosening due to excessive localized stress. Furthermore, the engagement distance between the connectors and mounting posts can be increased to prevent loose or stripped connectors, such as self-tapping screws.

[0012] In one embodiment, the assembly column is integrally formed with the shell. This integration creates a continuous, monolithic structure. Compared to a separate assembly column and shell that are joined together, this integrated structure can better withstand various external forces and offers greater structural strength.

[0013] In one embodiment, the outer surface of the mounting post extends towards the PCB board, the end face of the mounting post abuts against the PCB board, and a chamfer is formed on the outer side of the mounting post. This chamfer intersects both the end face and the outer surface of the mounting post, and is located between them. The abutment between the end face and the PCB board enhances the stability of the PCB board connection. The chamfer transition between the end face and the outer surface of the mounting post ensures that the parting line is located at the junction of the chamfer and the outer surface of the mounting post, preventing the parting surface from protruding from the mounting surface, even if there are burrs on the parting surface, thus further improving the tightness of the PCB board assembly.

[0014] In one embodiment, the connector has at least a first position and a second position when moving relative to the housing assembly. When the connector is in the first position, its length within the connection is L1; when the connector is in the second position, its length within the connection area is L2, where L2 is greater than L1. When the connector moves from the first position to the second position, a first thread is formed on the housing assembly, and a second thread is formed on the connector. The first thread mates with the second thread. By drilling holes in the connector, such as with a self-tapping screw, to achieve threaded engagement between the connector and the connection area, the accuracy and stability of PCB board mounting are improved. This design ensures that the PCB board is securely mounted, preventing loosening or detachment, thus improving the reliability and lifespan of the equipment.

[0015] In one embodiment, the connector is threaded into the first mounting hole. This threaded engagement improves the accuracy and stability of the PCB board mounting. This design ensures the PCB board is securely mounted, preventing loosening or detachment, thus enhancing the reliability and lifespan of the equipment.

[0016] In one embodiment, the connector includes a connecting rod and a connecting head. The connecting rod is disposed on the PCB board and located at the first mounting hole. After passing through the first mounting hole, the connecting rod engages with the connection area. The connecting head is disposed on the connecting rod and can abut or separate from the PCB board. The connector is used to connect the PCB board and the housing assembly, resulting in a secure assembly.

[0017] In one embodiment, the accommodating space has a rectangular cross-section. This rectangular cross-section increases the accommodating volume, allowing for more debris to be accommodated and preventing excessive debris from pushing up the PCB board. Furthermore, compared to complex curves or irregular shapes, the rectangular cross-section is relatively simple to manufacture, requiring less sophisticated equipment and processes, thus effectively reducing manufacturing difficulty. The connecting rod passes through the first mounting hole on the PCB board and engages with the second mounting hole, providing a clear installation direction and positioning reference for the connector. Operators can more easily and accurately insert the connector into the corresponding hole, ensuring the accuracy and stability of the connection. Simultaneously, the presence of the connecting head makes it easier to apply external force during installation, ensuring the connector is smoothly installed in place.

[0018] An electronic device includes: the PCB board mounting structure described above.

[0019] The second aspect of this application discloses a PCB board mounting structure. This structure includes a receiving space to collect debris generated during drilling, preventing the debris from affecting the fit between the PCB board and the housing assembly. Through the threaded engagement of the connector and the mounting post, and the secure connection between the connector and the PCB board, the PCB board can be tightly and firmly mounted on the housing assembly.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] Example 1

[0037] like Figure 1-10As shown, the first aspect of this embodiment discloses a PCB board mounting structure, including: a housing assembly 1, the housing assembly 1 having a connection area; a PCB board 2, the PCB board 2 being disposed on the housing assembly 1, the PCB board 2 having a first mounting hole 201; and a connector 3, the connector 3 being disposed on the PCB board 2 and located at the first mounting hole 201, the connector 3 passing through the first mounting hole 201 and engaging with the connection area, the connector 3 being movable relative to the housing assembly 1, the housing assembly 1, the PCB board 2, and the connector 3 enclosing to form a receiving space 102, the receiving space 102 being used to collect debris generated when the connector 3 moves relative to the housing assembly 1.

[0038] The first aspect of this application discloses a PCB board mounting structure. The inclusion space 102 ensures that debris generated by the housing assembly 1 during the drilling process of the connector 3 is contained within the inclusion space 102, preventing it from leaking out of the housing assembly 1 and lifting the PCB board 2. This design ensures a tight fit between the PCB board 2 and the housing assembly 1, resulting in a more compact assembly of the PCB board 2 and improving the assembly gap problem caused by debris in traditional methods. Furthermore, it eliminates the need for additional time to clean up the debris generated during drilling, offering good practicality. By forming a relatively enclosed space around the connector 3, debris from the first mounting hole 201 and the connection area can be effectively contained within the inclusion space 102, further preventing debris from lifting the PCB board 2.

[0039] like Figure 6-8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the connection area includes a second mounting hole 101 and a connection channel 103, the second mounting hole 101 communicates with the connection channel 103, the connector 3 passes through the first mounting hole 201 and the connection channel 103 in sequence and then mates with the second mounting hole 101, the portion of the connector 3 located in the connection channel 103, the channel wall of the connection channel 103, and the PCB board 2 enclose the receiving space 102. The configuration of the connection channel 103 provides a clear guide for the insertion and tightening of the connector 3. This design allows the operator to more easily and accurately pass the connector 3 through the first mounting hole 201 and smoothly mate it with the second mounting hole 101 along the connection channel 103, resulting in better installation stability of the PCB board 2 and preventing the PCB board 2 from shifting under the influence of external factors, thus affecting its performance.

[0040] like Figure 2-5As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the connecting channel 103 is greater than or equal to the cross-sectional area of ​​the second mounting hole 101. By making the cross-sectional area of ​​the connecting channel 103 greater than or equal to the cross-sectional area of ​​the second mounting hole 101, a larger accommodating space 102 is formed, providing more ample storage space for debris and preventing debris from accumulating and overflowing due to narrow space.

[0041] like Figure 2-5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the connecting channel 103 is located at the end of the second mounting hole 101. Because the connecting channel 103 is located at the end of the second mounting hole 101, that is, the connecting channel 103 is adjacent to the second mounting hole 101, the debris generated by the connector 3 during operation within the second mounting hole 101 will be more concentrated in the relatively enclosed area of ​​the receiving space 102. This design prevents debris from scattering throughout the housing assembly 1, thus preventing debris from pushing up the PCB board 2 and reducing the hassle of subsequent cleaning.

[0042] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: at least a portion of the cross-sectional area of ​​the receiving space 102 gradually increases in the direction toward the first mounting hole 201. By gradually increasing the cross-sectional area of ​​at least a portion of the receiving space 102 in the direction toward the first mounting hole 201, a funnel-shaped structure is formed. This design allows debris to move along the direction of the gradually increasing cross-sectional area after it is generated, and is eventually collected in the receiving space 102, avoiding random scattering of debris within the housing assembly 1 and improving the debris collection effect.

[0043] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a housing 11 and an assembly post 12, the assembly post 12 is disposed on the housing 11, the assembly post 12 has the connection area, and the assembly post 12, the PCB board 2, and the connector 3 enclose the receiving space 102. The assembly post 12 isolates the PCB board 2 from the housing 11, reducing the area of ​​direct contact between the PCB board 2 and the housing 11. This design avoids heat dissipation from the PCB board 2 causing thermal melting damage to the housing 11. Debris generated during the drilling process of the connector 3 is mainly collected within the space enclosed by the assembly post 12, the PCB board 2, and the connector 3, ensuring the installation stability and electrical reliability of the PCB board 2.

[0044] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of connectors 3 is multiple, the number of mounting posts 12 is multiple, the number of connectors 3 and mounting posts 12 is the same, and the connectors 3 and mounting posts 12 are matched one-to-one. Through the one-to-one matching of connectors 3 and mounting posts 12, the PCB board 2 can be fixed to the housing assembly 1 at multiple points. Compared with fixing with a single connector 3, multi-point fixing can more evenly distribute the weight and external force of the PCB board 2, avoiding deformation, bending or loosening of the PCB board 2 due to excessive local stress. Moreover, the engagement distance between the connectors 3 and mounting posts 12 can be increased to prevent connectors 3, such as self-tapping screws, from being loose or stripped.

[0045] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the assembly column 12 and the shell 11 are integrally formed. By integrating the assembly column 12 and the shell 11, they form a continuous, integral structure. Compared to the case where the assembly column 12 and the shell 11 are separate and combined through a connection, the integrated structure can better withstand various external forces and has better structural strength.

[0046] like Figure 2 , Figure 3 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer surface of the assembly pillar 12 extends toward the PCB board 2, the end face of the assembly pillar 12 abuts against the PCB board 2, and a chamfer 104 is formed on the outer side of the assembly pillar 12. The chamfer 104 intersects with both the end face and the outer surface of the assembly pillar 12, and is located between the end face and the outer surface of the assembly pillar 12. By abutting against the PCB board 2 with the end face, the connection of the PCB board 2 is more stable. The end face and the outer surface of the assembly pillar 12 are connected by a chamfer transition, so that the parting line is at the connection between the chamfer 104 and the outer surface of the assembly pillar 12, making the parting surface not on the mounting surface. Even if there are burrs on the parting surface, they will not push up the PCB board 2, further improving the tightness of the PCB board 2 assembly.

[0047] In addition to the features of the above embodiments, this embodiment further specifies that: when the connector 3 moves relative to the housing assembly 1, it has at least a first position and a second position; when the connector 3 is in the first position, its length within the connecting area is L1; when the connector 3 is in the second position, its length within the connecting area is L2, where L2 is greater than L1; when the connector 3 moves from the first position to the second position, a first thread is formed on the housing assembly 1, and a second thread is formed on the connector 3; the first thread and the second thread engage. By drilling holes in the connector 3, for example with self-tapping screws, the connector 3 engages with the threaded connection in the connecting area, improving the accuracy and stability of the PCB board 2 installation. This design ensures that the PCB board 2 is securely installed, not easily loosened or detached, thus improving the reliability and service life of the equipment.

[0048] In addition to the features of the above embodiments, this embodiment further specifies that the connector 3 is threadedly engaged with the first mounting hole 201. The threaded engagement of the connector 3 with the first mounting hole 201 improves the accuracy and stability of the PCB board 2 installation. This design ensures that the PCB board 2 is securely installed, preventing loosening or detachment, thus improving the reliability and service life of the equipment.

[0049] like Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connector 3 includes a connecting rod 31 and a connecting head 32. The connecting rod 31 is disposed on the PCB board 2 and located at the first mounting hole 201. The connecting rod 31 passes through the first mounting hole 201 and engages with the connecting area. The connecting head 32 is disposed on the connecting rod 31 and can abut or separate from the PCB board 2. The connector 3 is used to connect the PCB board 2 and the housing assembly 1, resulting in a strong and secure assembly.

[0050] Example 2

[0051] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the accommodating space 102 is rectangular. The rectangular cross-section of the accommodating space 102 increases its accommodating volume, allowing it to hold more debris and preventing excessive debris from pushing up the PCB board 2. Moreover, compared to some complex curves or irregular shapes, the processing technology for a rectangular cross-section is relatively simple, requiring less sophisticated processing equipment and processes, effectively reducing processing difficulty. The connecting rod 31 passes through the first mounting hole 201 on the PCB board 2 and engages with the second mounting hole 101, providing a clear installation direction and positioning reference for the connector 3. Operators can more easily and accurately insert the connector 3 into the corresponding hole, ensuring the accuracy and stability of the connection. Simultaneously, the presence of the connecting head 32 makes it easier to apply external force during installation, smoothly installing the connector 3 into place.

[0052] Example 3

[0053] This embodiment discloses an electronic device, including the PCB board mounting structure described above.

[0054] The second aspect of this application discloses a PCB board mounting structure. The PCB board mounting structure includes a receiving space 102 to collect debris generated during drilling, preventing the debris from affecting the fit between the PCB board 2 and the housing assembly 1. Through the threaded engagement between the connector 3 and the mounting post 12, and the secure connection between the connector 3 and the PCB board 2, the PCB board 2 can be tightly and securely mounted on the housing assembly 1.

[0055] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
