Description

Technical Field

[0001] This case relates to an electronic device, and more particularly to an electronic device and its grounding structure that can quickly complete grounding and assembly operations. Background Technology

[0002] Generally, in conventional electronic devices, to connect a circuit board to a metal casing for grounding, one end of a grounding wire or grounding terminal is usually secured to the circuit board with screws, and the other end of the grounding wire or grounding terminal is then electrically connected to the metal casing. However, this method requires screws and a grounding wire or grounding terminal, which is costly and time-consuming to assemble.

[0003] Some conventional electronic devices achieve grounding by riveting a grounding element to the circuit board and the metal casing. However, riveting grounding requires a riveting fixture, and the assembly process is time-consuming. Other conventional electronic devices achieve grounding by using spring contacts to fix the spring to the circuit board and make contact with the metal casing. However, the material of the spring is prone to elastic fatigue, which may lead to loosening.

[0004] In addition, the aforementioned methods of grounding by screws, riveting, and spring clips do not have the effect of positioning the circuit board. If the circuit board is to be positioned on the metal casing, an additional positioning device is required to assist in positioning the circuit board, which increases costs and complicates the assembly structure.

[0005] In view of this, it is necessary to develop an electronic device and its grounding structure that can quickly complete grounding and assembly operations in order to solve the problems faced by existing technologies. Summary of the Invention

The at least one clamping structure is connected to the base plate, extends toward the accommodating space, and includes a first clamping portion and a second clamping portion, wherein the first clamping portion and the second clamping portion are spaced apart. The circuit board is disposed within the accommodating space of the housing, and the at least one clamping structure positions the circuit board by penetrating the board body through the at least one through-hole, and the at least one ground wire is clamped between the first clamping portion and the second clamping portion of the at least one clamping structure to form a ground.

[0008] To achieve the aforementioned objective, another broad embodiment of this application provides a grounding structure for an electronic device. The grounding structure includes a circuit board, a base plate, and a clamping structure. The circuit board includes a board body, a through-hole, and a grounding wire, with the through-hole penetrating the board body.

[0061] Some typical embodiments that embody the features and advantages of this invention will be described in detail in the following description. It should be understood that this invention can have various variations in different forms, all of which do not depart from the scope of this invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit this invention.

[0062] Figure 1 This is a schematic diagram of the structure of an electronic device according to an embodiment of this case. Figure 2 for Figure 1 The diagram shown is an exploded view of the electronic device. Figure 3 for Figure 2 The diagram shows a partially enlarged view of the circuit board in region A, and... Figure 4 for Figure 2 A schematic diagram of the first exemplary clamping structure for the electronic device shown. Figures 1 to 4As shown, the electronic device 100 in this embodiment achieves rapid grounding and circuit board positioning through its grounding structure. The electronic device 100 includes a circuit board 1 and a housing 2. The circuit board 1 includes a board body 10, at least one through-hole 11, and at least one grounding wire 12. The at least one through-hole 11 penetrates the board body 10. The at least one grounding wire 12 is electrically connected to the board body 10 and spans across the at least one through-hole 11. The housing 2 includes a first housing component 2a and a second housing component 2b, wherein the first housing component 2a and the second housing component 2b are assembled together. The first housing component 2a includes a base plate 20, a plurality of side plates 21, at least one clamping structure 22, and an accommodating space 23. The plurality of side plates 21 are respectively adjacent to each other and respectively connected to the base plate 20 to define the accommodating space 23. The at least one clamping structure 22 is connected to the base plate 20 and extends toward the accommodating space 23, wherein the at least one clamping structure 22 is preferably perpendicular to the base plate 20, but is not limited thereto. At least one clamping structure 22 includes a first clamping portion 221 and a second clamping portion 222. The first clamping portion 221 and the second clamping portion 222 are spaced apart. In this embodiment, the circuit board 1, the base plate 20 and the clamping structure 22 form a grounding structure for the electronic device 100.

[0063] Figure 5A for Figure 2 The diagram shows a partial structural representation of the circuit board mounted on the housing, and... Figure 5B for Figure 2 The diagram shows a cross-sectional view of the circuit board mounted on the housing. Figure 5A and Figure 5B As shown, when the circuit board 1 is placed in the accommodating space 23 of the housing 2, the clamping structure 22 of the housing 2 penetrates the board body 10 through the through hole 11 of the circuit board 1, thereby positioning the circuit board 1 in the housing 2. The grounding wire 12 is clamped between the first clamping part 221 and the second clamping part 222 of the clamping structure 22 to form a ground. Through the aforementioned grounding structure, not only can the grounding operation be completed quickly, but the circuit board 1 is also positioned inside the housing 2, thereby reducing costs and saving assembly time.

[0064] In one embodiment, the entire housing 2 is made of metal. In another embodiment, the clamping structure 22 and the base plate 20 of the housing 2 are made of metal. Through a pressing assembly operation, the grounding wire 12 of the circuit board 1 is quickly connected to the clamping structure 22 made of metal, thereby achieving grounding of the circuit board 1.

[0065] In one embodiment, the clamping structure 22 of the housing 2 is formed by cutting a portion of the material of the base plate 20 and bending it toward the receiving space 23, and forming an opening 201 in the base plate 20, wherein the clamping structure 22 is connected to one side of the opening 201. In other words, the clamping structure 22 and the base plate 20 are integrally formed, thereby saving materials and reducing costs.

[0066] In this embodiment, the number of through holes 11 and grounding wires 12 on the circuit board 1 and the number of clamping structures 22 on the housing 2 are all the same. Preferably, the circuit board 1 includes two through holes 11 and two grounding wires 12, and the housing 2 includes two clamping structures 22. The two through holes 11 are located on two opposite sides of the circuit board 1, and the two grounding wires 12 are respectively connected across the two through holes 11. The two clamping structures 22 are respectively provided corresponding to the two through holes 11 on the circuit board 1. The two clamping structures 22 of the housing 2 pass through the two through holes 11 on the circuit board 1 and are respectively connected to the two grounding wires 12, thereby quickly completing the grounding operation and simultaneously positioning the circuit board 1 inside the housing 2, achieving the effect of reducing costs and saving assembly time.

[0067] Please see Figure 1 and Figure 2 In this embodiment, the first housing component 2a and the second housing component 2b of the housing 2 are assembled together to enclose the accommodating space 23, thereby preventing dust or moisture from entering the electronic device 100. In one embodiment, the second housing component 2b includes a top plate 24 and a plurality of side plates 25. The plurality of side plates 25 are adjacent to each other and are respectively connected to the top plate 24. The plurality of side plates 21 of the first housing component 2a are respectively connected to the plurality of side plates 25 of the second housing component 2b, thereby assembling the first housing component 2a and the second housing component 2b together. It should be emphasized that the plurality of side plates 21 of the first housing component 2a and the plurality of side plates 25 of the second housing component 2b can be connected by means such as, but not limited to, snap-fit ​​or locking.

[0068] Please see Figure 2 , Figure 3 and Figure 5A In this embodiment, the through hole 11 of the circuit board 1 is an elongated hole with a long side 11a, but this is not a limitation. The grounding wire 12 is linearly disposed across the through hole 11, that is, the two ends of the grounding wire 12 are located on the two opposite long sides of the through hole 11. The grounding wire 12 and the long side 11a of the through hole 11 have an angle θ, wherein the angle θ is an acute angle, preferably between 30 degrees and 60 degrees, and preferably 45 degrees. Through the design of the acute angle θ between the grounding wire 12 and the long side 11a of the through hole 11, the stress generated when the clamping structure 22 contacts the grounding wire 12 of the circuit board 1 is smaller, reducing the risk of breakage of the grounding wire 12.

[0069] Please see Figure 2 , Figure 4 and Figure 5BIn this embodiment, a clamping space 223 is provided between the first clamping portion 221 and the second clamping portion 222 of the clamping structure 22 of the housing 2. The clamping space 223 includes an open end 223a, a clamping portion 223b, and a buffer end 223c. The open end 223a is located at the free end of the clamping space 223, the buffer end 223c is located at the closed end of the clamping space 223, and the clamping portion 223b communicates between the open end 223a and the buffer end 223c. When the circuit board 1 is installed into the receiving space 23 of the housing 2 and the clamping structure 22 passes through the corresponding through hole 11 of the circuit board 1, the grounding wire 12 of the circuit board 1 enters the clamping space 223 from the open end 223a of the clamping structure 22 and is located in the clamping portion 223b. The buffer end 223c is structured to provide space for the elastic deformation of the first clamping part 221 and the second clamping part 222, so as to avoid damage to the first clamping part 221 and the second clamping part 222 due to the stress generated by contacting the board body 10 of the circuit board 1 or the grounding wire 12. In this embodiment, the distance between the first clamping part 221 and the second clamping part 222 at the buffer end 223c is greater than the distance between the clamping parts 223b, but it is not limited thereto.

[0070] In this embodiment, the first clamping portion 221 includes a first ramp portion 221a, corresponding to the opening end 223a of the clamping space 223. The second clamping portion 222 includes a second ramp portion 222a, corresponding to the opening end 223a of the clamping space 223. The distance between the first clamping portion 221 and the second clamping portion 222 gradually decreases from the free end of the opening end 223a toward the clamping portion 223b. The distance between the first clamping portion 221 and the second clamping portion 222 at the opening end 223a is greater than the distance between the clamping portions 223b, but is not limited thereto. When the circuit board 1 is disposed in the receiving space 23 of the housing 2 and the clamping structure 22 passes through the corresponding through hole 11 of the circuit board 1, the grounding wire 12 of the circuit board 1 enters the clamping space 223 from the opening end 223a along the first ramp portion 221a of the first clamping portion 221 and the second ramp portion 222a of the second clamping portion 222. This makes it easier to assemble the ground wire 12 of the circuit board 1 into the clamping space 223, avoiding damage to the clamping structure 22 due to assembly errors.

[0071] In one embodiment, the clamping structure 22 includes a support portion 224. The support portion 224 connects the first clamping portion 221 and the second clamping portion 222. Figure 5BAs shown, when the circuit board 1 is disposed in the accommodating space 23 of the housing 2, the support portion 224 is located between the bottom plate 20 of the housing 2 and the board body 10 of the circuit board 1, forming a first space B between the bottom plate 20 and the board body 10. Through the provision of the first space B, components or devices can be disposed on both sides of the board body 10 of the circuit board 1. For example, the electronic device 100 may include an insulating pad (not shown), an adhesive layer (not shown), and multiple electronic components (not shown), wherein the insulating pad, adhesive layer, and multiple electronic components are disposed in the first space B, but are not limited thereto.

[0072] In this embodiment, the width of the support portion 224 is greater than the width of the through hole 11. The plate body 10 includes a first surface 101 and a second surface 102, which are two corresponding surfaces. When the circuit board 1 is disposed in the housing 2, the first clamping portion 221 and the second clamping portion 222 of the clamping structure 22 of the housing 2 pass through the through hole 11 of the circuit board 1 and are exposed on the first surface 101 of the plate body 10 of the circuit board 1. A portion of the support portion 224 abuts against the second surface 102 of the plate body 10 of the circuit board 1 to provide support force and prevent the components from being damaged by force during assembly.

[0073] Figure 6A for Figure 2 A schematic diagram of the second exemplary clamping structure of the electronic device shown, and Figure 6B for Figure 6AThe diagram shows a partial side view of the electronic device's circuit board mounted on the housing. In one embodiment, the support portion 224 of the clamping structure 22 of the housing 2 includes a body 2241 and at least one first auxiliary support member 2242. The body 2241 includes a first side 2241a, a second side 2241b, a third side 2241c, and a fourth side 2241d. The first side 2241a and the second side 2241b are located on opposite sides of the body 2241, and the bottom plate 20 of the housing 2 is connected to the first side 2241a of the body 2241. The third side 2241c and the fourth side 2241d are located on opposite sides of the body 2241 and are adjacent to the first side 2241a and the second side 2241b, respectively. In this embodiment, the support portion 224 includes two first auxiliary support members 2242, but this is not a limitation, and their number and arrangement can be varied according to requirements. Two first auxiliary support members 2242 are respectively connected to the third side 2241c and the fourth side 2241d of the main body 2241 and extend from the main body 2241 in a first direction. The height of the two first auxiliary support members 2242 is equal to the length of the third side 2241c and the fourth side 2241d of the main body 2241, but is not limited thereto. The first direction is preferably perpendicular to the surface of the main body 2241, but is not limited thereto. When the circuit board 1 is disposed in the accommodating space 23 of the housing 2, the first auxiliary support members 2242 are located between the board body 10 of the circuit board 1 and the bottom plate 20 of the housing 2, and abut against the second surface 102 of the board body 10 of the circuit board 1 to provide support for the circuit board 1 and prevent the components from being damaged by force during assembly. In this embodiment, the first auxiliary support 2242 is formed by bending the body 2241. In other words, the first auxiliary support 2242 and the body 2241 are both formed by bending a portion of the material of the base plate 20 toward the accommodating space 23 after cutting. The first auxiliary support 2242, the body 2241 and the base plate 20 are integrally formed, thereby saving materials and reducing costs.

[0074] Figure 7A for Figure 2 A schematic diagram of the third exemplary clamping structure of the electronic device shown, and Figure 7B for Figure 7AThe diagram shows a partial side view of the electronic device's circuit board mounted on the housing. In one embodiment, the support portion 224 of the clamping structure 22 includes a body 2241 and a second auxiliary support member 2243. The body 2241 also includes a first side 2241a, a second side 2241b, a third side 2241c, and a fourth side 2241d. The second auxiliary support member 2243 is connected to the second side 2241b of the body 2241 and extends from the body 2241 toward a second direction. The second direction is preferably perpendicular to the surface of the body 2241 or parallel to the surface of the circuit board 1, but is not limited thereto. The second auxiliary support member 2243 includes a contact surface 2243a. When the circuit board 1 is disposed in the receiving space 23 of the housing 2, the contact surface 2243a of the second auxiliary support member 2243 abuts against the second surface 102 of the board body 10 of the circuit board 1, increasing the contact area with the board body 10 of the circuit board 1 and providing support force to prevent damage to the components during assembly. In this embodiment, the second auxiliary support 2243 is connected between the first clamping part 221, the second clamping part 222, and the body 2241. The first clamping part 221 and the second clamping part 222 are vertically connected to one side of the second auxiliary support 2243, and the body 2241 is vertically connected to the other side of the second auxiliary support 2243. The first clamping part 221 and the second clamping part 222 are formed by bending one side of the second auxiliary support 2243, and the second auxiliary support 2243 is formed by bending the second side 2241b of the body 2241. In other words, the first clamping part 221, the second clamping part 222, the second auxiliary support 2243, the body 2241, and the base plate 20 are integrally formed, thereby saving materials and reducing costs.

[0075] Figure 8A for Figure 2 A schematic diagram of the fourth exemplary clamping structure of the electronic device shown, and Figure 8B for Figure 8AThe diagram shows a partial side view of the electronic device's circuit board mounted on the housing. In one embodiment, the support portion 224 of the clamping structure 22 includes a body 2241 and at least one third auxiliary support member 2244. The at least one third auxiliary support member 2244 is formed by bending a portion of the material of the base plate 20 of the housing 2 toward the accommodating space 23 after cutting, and is perpendicular to the base plate 20, but is not limited thereto. In one embodiment, the at least one third auxiliary support member 2244 is connected to at least one side of the opening 201 of the base plate 20. In this embodiment, the support portion 224 includes two third auxiliary support members 2244, but is not limited thereto, and their number and arrangement can be varied according to requirements. The two third auxiliary support members 2244 are respectively spaced apart from the body 2241 of the support portion 224 and connected to two opposite sides of the opening 201 of the base plate 20, wherein the body 2241 and the two third auxiliary support members 2244 are respectively connected to different sides of the opening 201. The free ends of the two third auxiliary support members 2244 are equidistant from the base plate 20, and equidistant from the second side 2241b of the body 2241 of the support portion 224 and the base plate 20, but are not limited thereto. When the circuit board 1 is disposed in the accommodating space 23 of the housing 2, the two third auxiliary support members 2244 are located between the board body 10 of the circuit board 1 and the base plate 20 of the housing 2, and respectively abut against the second surface 102 of the board body 10 of the circuit board 1. Through the body 2241 and the two third auxiliary support members 2244 and other multiple support points, the circuit board 1 is provided with support force, so as to avoid damage to the components during the assembly process.

[0076] In some embodiments, the support portion 224 of the clamping structure 22 may include at least one or a combination of a first auxiliary support member 2242, a second auxiliary support member 2243, and a third auxiliary support member 2244, but this is not a limitation. The specific implementation is as described in the above embodiments, and therefore will not be repeated here. By combining the first auxiliary support member 2242, the second auxiliary support member 2243, and the third auxiliary support member 2244, the circuit board 1 is provided with support force and the contact area is increased, which can reduce the risk of damage to the components due to stress during assembly.

[0077] In summary, this invention provides an electronic device and its grounding structure. The device utilizes a clamping structure within the housing to pass through a perforation in the circuit board and connect to a grounding wire, enabling rapid grounding while simultaneously positioning the circuit board within the housing. This reduces costs and saves assembly time. The clamping structure is constructed from a portion of the base plate material, and the clamping structure and base plate are integrally molded, achieving material savings and cost reduction. Furthermore, the acute angle between the grounding wire and the perforation minimizes stress generated by the clamping structure in contact with the grounding wire, reducing the risk of grounding wire breakage. Moreover, the auxiliary support components within the clamping structure provide support for the circuit board and increase the contact area, preventing damage to components during assembly due to stress.
