Description

[0001] This application claims priority to Chinese Patent Application No. 202411296162.4, filed on September 18, 2024, entitled "Circuit Board Assembly and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic device technology, and in particular to a housing and an electronic device. Background Technology

[0003] A circuit board, as an insulating substrate used to support electronic components and achieve electrical connections, is typically composed of multiple layers of materials, including an insulating substrate, copper foil, and an adhesive layer. Its function is to provide physical support for electronic components while ensuring electrical connections in the circuit. To protect the circuit board from damage caused by water or impacts from other components, a casing is usually placed on it to cover and protect it. Furthermore, to ensure that the circuit board can communicate with the outside world, through-holes are provided in the casing, allowing wires to pass through and communicate with the outside environment.

[0004] In the process of developing this application, the inventors discovered that: Currently, the wiring holes on the housing are usually designed with clearance notches, which are connected to the edge of the housing. When installing the housing, wires may come out from the clearance notches, causing the housing and the circuit board to squeeze the wires together, resulting in damage to the wires and affecting the communication between the circuit board and the outside world. Furthermore, the wires that come out from the clearance notches may collide and become entangled with external live components, affecting the safety of the circuit board during use.

[0052] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0053] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0054] In traditional technology, the vias in circuit board assemblies are mostly simple openings or clearances on the housing where they are needed, serving to allow wire harnesses to pass through or avoid them. Figure 1 and Figure 2In the illustrated embodiment, an opening 101 for the wire harness to pass through is provided on the housing 1000. When assembling the housing 1000 with the circuit board 5, the original wire harness 201 on the circuit board 5 is first straightened and then passed through the opening 101 from the inside. Then, the housing 1000 is placed downwards on the circuit board 5. However, this method requires sufficient space for wire passing before assembling the housing 1000 and the circuit board 5, and also requires a larger amount of operable wire length, which increases the cost and makes the operation more cumbersome. Furthermore, if the wire harness has terminals, there is a problem that it may be blocked by the wire passage hole and unable to pass through it. Figure 3 and Figure 4 In the embodiment shown, a clearance notch 101' is provided at the location of the wiring harness on the housing 1000. This allows the housing 1000 to be directly closed onto the circuit board 5 when assembling the housing 1000 and the circuit board 5, without interference between the original wiring harness 201 and the housing 1000. However, this method leaves the original wiring harness 201 without a support structure and it will move within the notch. Since the circuit board assembly usually has live parts around it in application, the wiring harness may come into contact with other live parts when moving within the clearance notch 101'. At the same time, if the notch is not deep enough, there is a risk of wire compression.

[0055] To address the aforementioned technical problems, this application provides a housing 1000. Please refer to [link / reference]. Figures 5 to 10 The cover 1000 includes a base plate 1 and a side plate 2. One end of the side plate 2 is disposed on the base plate 1. The base plate 1 and the side plate 2 together enclose a receiving groove 3. The receiving groove 3 is used to accommodate circuit boards or other electronic components that need to be covered. The side plate 2 is provided with a snap hole 21 that connects to the receiving groove 3. The side plate 2 is also provided with a guide hole 22 that connects to the snap hole 21 and extends to the other end of the side plate 2, so that the guide hole 22 is an open opening, which facilitates the passage of wires. The guide hole 22 is used to guide the wires of the circuit board into the snap hole 21. The open guide hole 22 makes it easier for users to insert wires into the snap hole 21 compared to the closed guide hole 22, which improves installation efficiency and optimizes the user experience.

[0056] Understandably, the opening forms of the guide hole 22 and the locking hole 21 are varied, including but not limited to: directly drilling holes in a part of the side plate 2, opening a clearance opening and setting a spring arm, etc.

[0057] It should be noted that the number of side panels 2 is a positive integer greater than or equal to two. The selection is based on the actual equipment that needs to be covered. If part of the housing in the equipment can be used as a shared side wall, the number of side walls can be reduced, such as using three or two, etc.

[0058] In some embodiments, please refer to Figure 6The side plate 2 is provided with a clearance opening 2a, which extends to the other end of the side plate 2. An elastic component 4 extends from the side plate 2 toward the clearance opening 2a. The elastic component 4 divides the clearance opening 2a into a locking hole 21 and a guide hole 22. Through the setting of the elastic component 4, the area within the clearance opening 2a is reasonably divided.

[0059] Furthermore, in some embodiments, the elastic component 4 includes a first elastic arm 41, one end of which is connected to the inner wall of the clearance opening 2a, and the other end of which is wound within the clearance opening 2a. The hollow core of the first elastic arm 41 is a locking hole 21. The hollow core formed by the winding of the first elastic arm 41 (or referred to as a U-shaped elastic arm structure) significantly extends the path of the wire moving from the center of the hollow core to outside the clearance opening 2a, thereby reducing the external vibration of the wire. The risk of the wire falling off the clearance opening 2a under adverse factors such as shaking is reduced, which improves the stability of the wire installed in the clearance opening 2a. The first elastic arm 41 and the inner wall of the clearance opening 2a enclose a guide hole 22. The guide hole 22 formed by this situation is generally long and narrow, which effectively limits the wire in the guide hole 22 and reduces the degree of shaking of the wire. Furthermore, it also increases the difficulty of the wire detaching from the clearance opening 2a at the locking hole 21, which further improves the stability of the wire installed in the clearance opening 2a.

[0060] Specifically, the first spring arm 41 includes a first arm portion 411, a second arm portion 412, a third arm portion 413, a fourth arm portion 414, and a fifth arm portion 415. One end of the first arm portion 411 is connected to an inner wall of the clearance opening 2a. The other end of the first arm portion 411, the second arm portion 412, the third arm portion 413, the fourth arm portion 414, and the fifth arm portion 415 are connected sequentially, and the first arm portion 411, the second arm portion 412, the third arm portion 413, the fourth arm portion 414, and the fifth arm portion 415 are arranged in a coiled configuration. Furthermore, the first arm portion 411, the second arm portion 412, the third arm portion 413, the fourth arm portion 414, and the fifth arm portion 415 are arranged in a coiled configuration. Arm 413, fourth arm 414 and fifth arm 415 are wound with a hollow core; second arm 412 is separated from the other inner wall of the clearance opening 2a by a first gap 221a, third arm 413 is separated from the bottom of the clearance opening 2a by a second gap 222a, fourth arm 414 is separated from the inner wall of the clearance opening 2a by a third gap 223a, and fourth arm 414 is separated from the first arm 411 by a fourth gap 224a. The first gap 221a, second gap 222a, third gap 223a and fourth gap 224a are connected in sequence to form a guide hole 22.

[0061] In some embodiments, the first arm 411, the third arm 413, and the fifth arm 415 are arranged parallel to each other, and the second arm 412 and the fourth arm 414 are arranged parallel to each other; a first rounded chamfer 41a is provided at the connection between the second arm 412 and the third arm 413, and / or a second rounded chamfer 41b is provided at the connection between the third arm 413 and the fourth arm 414, and / or a third rounded chamfer 41c is provided at the connection between the fourth arm 414 and the fifth arm 415. The provision of the first rounded chamfer 41a, the second rounded chamfer 41b, and the third rounded chamfer 41c facilitates the movement of the wire within the guide hole 22, improves the smoothness and fluidity of wire insertion, and enhances the user experience.

[0062] In some embodiments, a fifth rounded chamfer 41d is provided at the connection position of the first arm 411 and the second arm 412, and / or a sixth rounded chamfer 41e is provided at the port of the other inner sidewall of the clearance opening 2a facing the guide hole 22. The fifth rounded chamfer 41d and the sixth rounded chamfer 41e make the port of the guide hole facing the outside form a flared local segment, thereby improving the user experience of the wire sliding into the guide hole 22.

[0063] Furthermore, in some embodiments, the fifth arm 415 is provided with a seventh rounded chamfer 41f at the end opposite to the fourth arm 414, so that the insertion operation of the wire when it passes through the guide hole 22 into the locking hole 21 is smoother than that of the right-angled end of the fifth arm 415, and also reduces the friction of the right-angled end of the fifth arm 415 on the wire, thus enhancing the protection of the wire.

[0064] It should be noted that the widths of the first gap 221a, the second gap 222a, the third gap 223a, and the fourth gap 224a mentioned above need to be controlled within a reasonable range to allow the passage of wires. Since the diameters of wires in different devices are different, the first gap 221a, the second gap 222a, the third gap 223a, and the fourth gap 224a need to be controlled according to the actual equipment used.

[0065] Understandably, the first arm 411, the second arm 412, the third arm 413, the fourth arm 414, and the fifth arm 415 are arranged in a continuous rod shape. Since the first elastic arm 41 can generate elastic deformation, in some embodiments, the widths of the first gap 221a, the second gap 222a, the third gap 223a, and the fourth gap 224a can be gradually reduced. For example, the width of the first gap 221a is greater than the width of the second gap 222a, the width of the second gap 222a is greater than the width of the third gap 223a, and the width of the third gap 223a is greater than the width of the fourth gap 224a. The width of the guide hole 22 thus decreases linearly. This linearly decreasing width of the guide hole 22 facilitates the insertion of wires from the outside into the card hole 21, improving the user's experience in inserting wires. It should be noted that for this type of guide hole 22 with a linearly decreasing width, the width of the fourth gap 224a needs to be equal to or greater than the diameter of the wire, or the width of the wire needs to be less than or equal to the maximum width of the first elastic arm 41 after elastic deformation.

[0066] Understandably, the first arm 411, the second arm 412, the third arm 413, the fourth arm 414 and the fifth arm 415 mentioned above can be added according to actual needs, thereby extending the length of the first spring arm 41; or they can be reduced according to actual needs, thereby shortening the length of the first spring arm 41.

[0067] In other embodiments, please refer to Figure 7 and Figure 8 The elastic component 4 includes a second elastic arm 42 and a third elastic arm 43. One end of the second elastic arm 42 is connected to an inner wall of the clearance opening 2a, and one end of the third elastic arm 43 is connected to the other end of the second elastic arm 42. The third elastic arm 43 extends toward the bottom of the clearance opening 2a. The third elastic arm 43 and the bottom of the clearance opening 2a have a fifth gap 221b, and the third elastic arm 43 and the other inner wall of the clearance opening 2a have a sixth gap 222b. The fifth gap 221b and the sixth gap 222b communicate to form a guide hole 22. The second elastic arm 42, the third elastic arm 43 and an inner wall of the clearance opening 2a enclose a locking hole 21.

[0068] Furthermore, the second spring arm 42 is parallel to the bottom of the clearance opening 2a, and the second spring arm 42 is perpendicular to the third spring arm 43, so that the area of ​​the locking hole 21 is increased compared with the area of ​​the locking hole 21 formed by the first spring arm 41, making it easier to insert and store multiple wires.

[0069] It is understandable that a fourth rounded chamfer 42a can be provided at the end of the sixth gap 222b away from the bottom of the clearance opening 2a, and the number of fourth rounded chamfers 42a is a positive integer greater than or equal to one. For example, in this embodiment, it is preferred that there are two fourth rounded chamfers 42a, one fourth rounded chamfer 42a is located in the third spring arm 43, and the other fourth rounded chamfer 42a is located in the inner sidewall of the clearance opening 2a that is parallel to and adjacent to the third spring arm 43.

[0070] In some embodiments, the end of the third spring arm 43 away from the second spring arm 42 is provided with a first chamfer 431, which improves the smoothness of the operation when the wire is inserted into the card hole 21 along the sixth gap 222b and saves the time of inserting the wire.

[0071] In some other embodiments, please refer to Figure 9 and Figure 10 The elastic component 4 includes a fourth elastic arm 44 and a fifth elastic arm 45. One end of the fourth elastic arm 44 is connected to one inner wall of the clearance opening 2a, and one end of the fifth elastic arm 45 is connected to the other inner wall of the clearance opening 2a. The other ends of the fourth elastic arm 44 and the fifth elastic arm 45 extend towards each other, and are spaced apart to form a guide hole 22. The fourth elastic arm 44 and the fifth elastic arm 45 together with the bottom of the clearance opening 2a form a locking hole 21. In this structure, the guide hole 22 is located in the middle of the clearance opening 2a. The guide hole 22 formed by the fourth elastic arm 44 and the fifth elastic arm 45 extending towards each other has a bidirectional elastic clamping function. When the wire enters the locking hole 21 through the guide hole 22, the fourth elastic arm 44 and the fifth elastic arm 45 can simultaneously undergo elastic deformation to both sides. This reduces the insertion resistance and creates a symmetrical clamping effect on the wire through bidirectional rebound force, preventing the wire from automatically detaching after entering the locking hole 21 through the guide hole 22. If it is necessary to remove the wire harness from the receiving groove, the fourth elastic arm 44 and the fifth elastic arm 45 can be manually deformed to release the wire. Compared with a single-sided elastic arm structure, this design provides more uniform contact pressure.

[0072] Furthermore, the first partial segment 441 of the opposing fourth elastic arm 44 and the second partial segment 451 of the fifth elastic arm 45 are both bent toward the bottom of the clearance opening 2a, thereby causing the guide hole 22 to form a trumpet-shaped guide segment 22a (or a V-shaped notch in some embodiments) and a straight segment 22b, wherein the width of the trumpet-shaped guide segment 22a is greater than the width of the straight segment 22b. The structure of the trumpet-shaped guide segment 22a is used to guide the direction of the user's wire insertion when the user inserts the wire, thereby improving the convenience of user operation. Furthermore, the first partial segment 441 of the opposing fourth spring arm 44 and the second partial segment 451 of the fifth spring arm 45 are both bent toward the bottom of the clearance opening 2a, which also reasonably divides the space inside the jack hole 21. Specifically, the first partial segment 441 of the fourth spring arm 44 forms a first receiving area 21a1 between itself and one side wall of the clearance opening 2a, and the second partial segment 451 of the fifth spring arm 45 forms a second receiving area 21a2 between itself and the other side wall of the clearance opening 2a. The first receiving area 21a1 and the second receiving area 21a2 constitute the receiving functional area 21a inside the jack hole 21. The remaining area inside the jack hole 21 is a temporary storage area 21b. The receiving functional area 21a is used to preferentially receive wires, and the temporary storage area 21b is used to store wires exceeding the capacity of the receiving functional area 21a, or to temporarily store wires when transferring them to the receiving functional area 21a, so that wires can be placed into the first receiving area 21a1 and the second receiving area 21a2 respectively.

[0073] Understandably, through the guide hole 22 and the locking hole 21 structure formed by the fourth spring arm 44 and the fifth spring arm 45, after the cover 1000 is fastened to the circuit board, the wires on the circuit board do not need to be bent and can enter the locking hole from the guide hole. This allows the wires to be connected to the outside without reserving a large length, thereby saving the cost of using the wires. Moreover, in this embodiment, the wire 6 is set as a trumpet-shaped guide section 22a, which can easily enter the locking hole 21 and is not easy to come out from the clearance opening 2a. If the wire is to come out from the clearance opening 2a, the trumpet-shaped guide section 22a can be enlarged by pushing the fourth spring arm and / or the fifth spring arm to deform it, so that the wire can smoothly come out from the clearance opening 2a.

[0074] It should be noted that the first spring arm 41, the second spring arm 42, the third spring arm 43, the fourth spring arm 44 and the fifth spring arm 45 mentioned above are all integrally formed with the side plate 2, so as to reduce the processing difficulty of the cover 1000, reduce the manufacturing cost and enhance market competitiveness.

[0075] In this embodiment, the cover 1000 includes a base plate 1 and a side plate 2. One end of the side plate 2 is disposed on the base plate 1. The base plate 1 and the side plate 2 together enclose a receiving groove 3. The receiving groove 3 is used to accommodate circuit boards or other electronic components that need to be covered. The side plate 2 is provided with a snap hole 21 that communicates with the receiving groove 3. The side plate 2 is also provided with a guide hole 22 that communicates with the snap hole 21 and extends to the other end of the side plate 2, so that the guide hole 22 presents an open opening, which facilitates the passage of wires. The guide hole 22 is used to guide the wires of the circuit board into the snap hole 21. The open guide hole 22 makes the operation of inserting wires into the snap hole 21 easier for the user compared to the closed guide hole 22, improving installation efficiency and optimizing the user experience.

[0076] This application also provides an electronic device embodiment 2000, please refer to [link / reference]. Figure 11 The device includes a circuit board 5, wires 6, a bracket (not shown) and the aforementioned cover 1000. The circuit board 5 is disposed on the bracket. The cover 1000 covers the circuit board 5 and is disposed on the bracket so that the circuit board is accommodated in the receiving groove 3, and the bracket blocks the opening of the receiving groove 3.

[0077] It is understood that the specific structure and function of the cover 1000 can be referred to the above embodiments, and will not be repeated here.

[0078] Existing electronic devices are equipped with large circuit boards. If a component on the circuit board is damaged or worn out and needs to be replaced, the entire circuit board must be disassembled and replaced. This wastes the components on the circuit board that are still in good working order, resulting in high maintenance costs and high maintenance difficulty, and thus limiting the maintenance capabilities.

[0079] To address the aforementioned problems with existing circuit board assemblies and to design a circuit board assembly that is both easy to operate and reduces maintenance costs, this application provides a circuit board assembly. Figure 1 and Figure 2 This illustrates a circuit board assembly provided in one embodiment of the prior art. Figure 3 and Figure 4 Another embodiment of the circuit board assembly is shown. In this embodiment, the circuit board assembly includes a circuit board 5 and a cover 1000 covering the circuit board 5. The cover 1000 is a whole plastic cover, and the circuit board 5 is also a whole circuit board. The cover 1000 can be fixed to the circuit board 5 with bolts to form a circuit board assembly. When a component on the circuit board 5 is damaged, the cover 1000 needs to be removed and the entire circuit board 5 needs to be replaced. The remaining components on the circuit board 5 can no longer be used. Therefore, the current circuit board assembly with this structure has a very high cost for maintenance.

[0080] To address the aforementioned problems, embodiments of this application provide a circuit board assembly, such as... Figures 12-25 As shown, the circuit board assembly includes: a circuit board 5 and a housing structure; the circuit board 5 includes a main circuit board 51 and at least one sub-circuit board 52, each sub-circuit board 52 having an electrical connection terminal 521 connected to the main circuit board 51; the housing structure includes the aforementioned cover 1000 and at least one module box 7, the cover 1000 being configured to cover the main circuit board 51, the cover 1000 being provided with mounting holes 11 corresponding one-to-one with the module boxes 7, each module box 7 being configured to be detachably mounted in the mounting hole 11.

[0081] Each sub-circuit board 52 is configured to be installed in a module box 7. When the cover 1000 covers the main circuit board 51 and the module box 7 with the sub-circuit board 52 is installed in the mounting hole 11, the electrical connection terminal 521 of the sub-circuit board 52 is connected to the main circuit board 51.

[0082] In the technical solution provided by the embodiments of this application, the cover 1000 is configured to cover the main circuit board 51 to form the main board module 200, while certain components (such as easily damaged or short-life components) are set on the sub-circuit board 52. After the sub-circuit board 52 is installed in the module box 7, the sub-module 100 as a whole is installed in the mounting hole 11 of the main board module 200. The module box 7 can act as a cover for the sub-circuit board 52. In this way, when replacing damaged components or maintaining components, it is not necessary to disassemble the cover 1000. The sub-module 100 can be removed from the mounting hole 11 to replace or repair the components on the sub-circuit board 52. The disassembly and assembly are simple and convenient, saving time and effort. Moreover, when components are damaged, it is not necessary to replace the entire circuit board, which can greatly save the cost of components and effectively reduce the later maintenance cost.

[0083] In some embodiments, the cover 1000 can be fixed to the main circuit board 51 by bolt connection, or by snap-fit ​​connection.

[0084] In one embodiment, the module box 7 is configured to be installed in the mounting hole 11 of the cover 1000 by snap-fit.

[0085] like Figure 12-14 This shows a sample of a shell 1000. Figures 15-16 This shows module box 7 in an example, such as Figures 15-16 As shown, elastic arms 71 are respectively provided on opposite sides of the module box 7, and snap-fit ​​parts 711 are provided on the elastic arms 71, such as... Figures 12-14As shown, a slot 113 is provided on the side wall 111 of the mounting hole 11 of the cover 1000. The module box 7 is installed in the mounting hole 11 by engaging the slot 113 on both sides of the slot 711. By pressing the elastic arms 71 on both sides, the slot 711 can be released from the slot 113, thereby removing the module box 7. Specifically, the module box 7 can be removed from the mounting hole 11 by pinching the elastic arms 71 on both sides of the module box 7 with your fingers.

[0086] It is understood that the module box 7 is not limited to being installed in the mounting hole 11 by snap-fit. For example, the module box 7 can also be installed in the mounting hole 11 by tight fit. That is, the module box 7 can be installed in the mounting hole 11 by insertion and disassembled from the mounting hole 11 by pulling it out. Alternatively, the module box 7 can be provided with a bolt connection part, and the module box 7 can be detachably connected to the cover 1000 by bolts.

[0087] In some embodiments, the sub-circuit board 52 is fixed to the module box 7 by bolts.

[0088] exist Figures 15-18 In the example, module box 7 is a square box with an opening at the bottom. Sub-circuit board 52 is mounted on module box 7 through the bottom opening, and electrical connection terminal 521 extends from the bottom of module box 7. (Refer to...) Figure 12 The state shown is as follows. Multiple bolt connection parts 72 are provided at the bottom of the module box 7. When the sub-circuit board 52 is installed into the module box 7 through the bottom opening, the sub-circuit board 52 can be fixed to the bolt connection parts 72 by bolts.

[0089] like Figures 12-15 As shown, the mounting hole 11 is a square hole adapted to the square box body of the module box 7. The square hole has side walls 111 on all four sides, and the bottom of two opposite side walls 111 is connected to a bottom wall 112. An opening is formed between the bottom walls 112 on both sides. The sub-circuit board 52 is limited by the bottom wall 112, and the electrical connection terminal 521 is connected to the main circuit board 51 through the opening between the bottom walls 112 on both sides.

[0090] Understandably, the module box 7 can also be of other shapes, as long as it can cover the circuit board 52 and be installed in the mounting hole 11.

[0091] For example, in an embodiment of this application, a plug-in portion 511 is provided on the main circuit board 51, and an electrical connection terminal 521 on the sub-circuit board 52 is configured to be electrically connected to the main circuit board 51 by inserting into the plug-in portion 511.

[0092] exist Figures 19-25In the example, the insertion portion 511 on the main circuit board 51 includes two elastic clips, and the electrical connection terminal 521 is a plug. When the plug is inserted between the two clips, the two clips elastically hold the clips together, thereby ensuring the electrical connection between the sub-circuit board 52 and the main circuit board 51. Of course, the electrical connection terminal 521 on the sub-circuit board 52 can also achieve electrical connection by abutting against the electrical contact portion of the main circuit board 51.

[0093] Figure 24 and Figure 25 The image shows the module box 7 installed in the mounting hole 11. The snap-fit ​​parts 711 on the two elastic arms 71 of the module box 7 are respectively snapped into the slots 113 of the two side walls 111 of the mounting hole 11. The electrical connection terminal 521 installed below the sub-circuit board 52 of the module box 7 is inserted into the insertion part 511 of the main circuit board 51. The bottom walls 112 on opposite sides of the mounting hole 11 can limit the sub-circuit board 52.

[0094] The following is based on Figures 17-22 The assembly and disassembly process of a circuit board assembly is described in one embodiment.

[0095] In this example, the installation and removal of a relay are used as an example, such as... Figure 17 As shown, a relay is installed on the sub-circuit board 52. Of course, other components can also be installed on the sub-circuit board 52.

[0096] 1. Insert the sub-circuit board 52 with relays into the module box 7, and fix the sub-circuit board 52 to the module box 7 with bolts to form a sub-module 100, such as... Figure 18 The state shown.

[0097] 2. For example Figure 19 and Figure 20 As shown, the cover 1000 is placed on the main circuit board 51 with the plug-in part 511 and the wire 6 from top to bottom. The wire 6 is inserted into the wire outlet 12 from the inlet 14 at the bottom of the cover 1000 and extends out from the wire outlet 12. The cover 1000 and the main circuit board 51 are fixed together by bolts to form the main board module 200.

[0098] 3. For example Figure 21 As shown, the submodule 100 is installed into the mounting hole 11 of the mainboard module 200, wherein the module box 7 of the submodule 100 is snapped into the mounting hole 11, and the electrical connection terminal 521 of the sub-circuit board 52 is inserted into the plug-in part 511 of the main circuit board 51, thereby assembling into a whole.

[0099] Multiple sub-modules 100 can be configured, and each sub-module 100 can be inserted into its corresponding mounting hole 11, such as... Figure 21 and Figure 22As shown, four sub-modules 100 are installed on the motherboard module 200. Then, the connection points are checked. Assembly is complete, and the assembled state is as follows. Figure 22 As shown. Conversely, if it is necessary to disassemble or replace the relay, after disconnecting the power to the circuit board assembly, first pinch the elastic arms 71 on both sides of the submodule 100 and lift it outwards to separate the submodule 100 from the mainboard module 200. Then, disassemble and replace the sub-circuit board 52 of the submodule 100. Finally, install the submodule 100 with the replaced sub-circuit board 52 onto the mainboard module 4. This is simple and quick, and saves on component and maintenance costs.

[0100] This application embodiment also provides a housing structure for a circuit board 5, the circuit board including a main circuit board 51 and at least one sub-circuit board 52, each sub-circuit board 52 having an electrical connection terminal 521 electrically connected to the main circuit board 51.

The cover 1000 is provided with mounting holes 11 corresponding to the module boxes 7 one by one. Each module box 7 is configured to be detachably mounted in the mounting hole 11.

[0101] Each module box 7 is configured to be able to install a sub-circuit board 52. When the cover 1000 covers the main circuit board 51 and the module box 7 with the sub-circuit board 52 is installed in the mounting hole 11, the electrical connection terminal 521 of the sub-circuit board 52 is connected to the main circuit board 51.

[0102] In some embodiments, elastic arms 71 are respectively provided on opposite sides of the module box 7, and snap-fit ​​portions 711 are provided on the elastic arms 71. A slot 113 is provided on the wall of the mounting hole 11. The module box 7 is installed in the mounting hole 11 by snapping the snap-fit ​​portions 711 into the slot 113. The module box 7 is disassembled by pressing the elastic arms 71 on both sides to release the snap-fit ​​portions 711 from the slot 113.

[0103] The main board module 200 is formed by assembling the housing 1000 of the housing structure with the main circuit board 51, and the sub-module 100 is formed by assembling the module box 7 with the sub-circuit board 52. The specific process of installing the sub-module 100 into the mounting hole 11 of the main board module 200 can be referred to the description of the above embodiment, and will not be repeated here.
