Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding, in particular to a shielding cover and an electronic device. Background Art

[0002] When some electronic components in electronic equipment are running at the same time, they may cause internal interference or electromagnetic interference with the outside world. Therefore, an electromagnetic compatibility (EMC) shielding cover is required during circuit design.

[0003] EMC shielding covers are generally used to cover electronic components that need to be shielded, and are in surface contact with the circuit board to form a shielding space, thereby achieving EMC shielding. However, since the contact between the EMC shielding cover and the circuit board is surface contact, manufacturing errors and installation errors (such as flatness tolerance) will occur during the manufacturing and assembly process. In other words, the EMC shielding cover and the circuit board cannot be fully in contact, which is easy to cause EMC leakage, thereby affecting the electromagnetic shielding effect. In addition, the form of surface contact will also occupy a large area of ​​the circuit board, thereby affecting the demand for miniaturization and integration of electronic equipment, and also increasing the manufacturing cost of the circuit board. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that the existing surface contact design between the shielding cover and the circuit board results in insufficient contact, thus leading to poor electromagnetic shielding effect, and the problem of occupying too much circuit board area. The utility model provides a shielding cover and an electronic device, which can effectively absorb manufacturing errors and assembly errors, so that the shielding cover is in full contact with the circuit board, and effectively enhance the electromagnetic shielding effect. At the same time, it also provides a method of line contact between the shielding cover and the circuit board instead of surface contact, which effectively improves the utilization rate of the circuit board, reduces the utilization area of ​​the circuit board, and reduces the cost of the circuit board.

[0008] In the shielding scheme of the circuit board and the shielding cover, the traditional surface contact method between the two often has problems, for example: it is not easy for the planes to contact each other, so the processing and installation accuracy of the two planes are required to be high; the circuit board may sometimes warp and deform, thereby affecting the contact between the planes; there are manufacturing errors or assembly errors in the manufacturing process of the circuit board and the shielding cover, resulting in no contact or poor contact between the circuit board and the shielding cover.

At the same time, the plurality of connectors of the embodiment of the present application are arranged at intervals from each other, and each connector is relatively independent, that is, when making line contact with, for example, a circuit board, they will not affect each other, further enhancing the contact between the plurality of connectors and the circuit board.

In other words, the shielding cover of the electronic device of the embodiment of the present application is suitable for the design form in which the first part to be shielded and the circuit board are arranged in the first direction.

DETAILED DESCRIPTION

[0041] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0042] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0043] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0044] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0045] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] See also Figure 1a and Figure 1b , Figure 1a and Figure 1b The shielding cover 100 in some implementation modes of the embodiment of the present application is exemplarily shown. Figure 1a A perspective view showing the shielding cover 100 connected to a circuit board 200; Figure 1b An exploded view of the shielding cover 100 , the circuit board 200 , and the high-frequency component 300 is shown.

[0048] It can be seen that different high-frequency components 300 are electrically connected to the circuit board 200 . These high-frequency components 300 include, for example, IGBT (Insulated Gate Bipolar Transistor) power modules, signal cables, etc., and have the common feature that they can emit electromagnetic interference signals.

[0049] Continue reading Figure 1a and Figure 1b The shielding cover 100 has an electromagnetic shielding function, and the bottom of the shielding cover 100 is a connecting portion 110. Figure 1aAs shown, it can be seen that in this embodiment, the connection portion 110 of the shielding cover 100 is flat, and the connection portion 110 directly contacts the circuit board 200 to shield the high-frequency component 300 .

[0050] However, the shielding cover 100 using this embodiment may have the problem of insufficient contact, thereby affecting the shielding effect. The reasons are: on the one hand, the surface contact design between the connecting portion 110 and the circuit board 200 cannot absorb manufacturing errors and assembly errors, such as the straightness tolerance; on the other hand, the surface contact design is also prone to bring adverse risks such as warping of the circuit board 200.

[0051] Based on this, see Figure 2 and Figure 3 The embodiment of the present application provides a shielding cover 1 and an electronic device using the shielding cover 1. Figure 2 A three-dimensional diagram of a shielding cover 1 according to an embodiment of the present application is exemplarily shown; Figure 3 An exploded view of the shielding cover 1 according to an embodiment of the present application is exemplarily shown.

[0052] The shielding cover 1 of the embodiment of the present application includes a shielding cover body 2 and a plurality of connectors 3. For example, the shielding cover body 2 is a metal shell, and holes and seams may be provided on the shielding cover body 2, which is not limited in the embodiment of the present application. For example, the plurality of connectors 3 are metal springs, so that the shielding cover 1 and the circuit board 5 are in elastic contact, thereby enhancing the shielding effect.

[0053] For example, Figure 2 and Figure 3 The shielding cover body 2 shown is an irregular rectangular structure, but this shape is only one possible implementation of the embodiment of the present application. The shielding cover body 2 can also be other shapes, such as square, ellipse, trapezoid, etc. The embodiment of the present application does not limit the shape of the shielding cover body 2, and it can be selected according to the actual application. For example, the shape of the shielding cover body 2 can be determined according to the arrangement of the circuit board 5.

[0054] Continue reading Figure 2 and Figure 3 It can be seen that the bottom of the shielding cover body 2 (i.e. Figure 2 and Figure 3 A plurality of connectors 3 are provided (indicated by the Z2 direction), and the plurality of connectors 3 are arranged around the bottom of the shielding cover body 2, and the plurality of connectors 3 are spaced apart from each other ( Fig. 9 More clearly shown), so that each connector 3 can exist relatively independently, so when they contact the circuit board 5, they will not affect each other.

[0055] The embodiment of the present application does not limit the number of connectors 3. As long as multiple connectors 3 can achieve line contact with the circuit board 5 as described below to improve the shielding effect of the shielding cover 1, they all fall within the protection scope of the embodiment of the present application.

[0056] See also Figure 4 Combined with Figure 2 , Figure 4 An enlarged view of a part of the connector 3 is shown as an example. It can be seen that one end of the connector 3 is connected to the bottom of the shielding cover body 2 (i.e. Figure 4 The other end of each connector 3 includes a contact edge 30. At least a portion of all the contact edges 30 is used for line contact with the circuit board 5, so that the shielding cover body 2 and the plurality of connectors 3 form a shielding space 4.

[0057] At least a portion of all the contact edges 30 are in line contact with the circuit board 5, which includes at least two situations: (1) the corresponding contact edges 30 of all the connectors 3 in the shielding cover 1 are in line contact with the circuit board 5; (2) the corresponding contact edges 30 of a portion of the connectors 3 in the shielding cover 1 (that is, a portion of the contact edges 30 among all the contact edges 30) are in line contact with the circuit board 5, and the other portion is not in line contact with the circuit board 5. The following will exemplify these two situations with Example 1 and Example 2, respectively, but the embodiments of the present application are not limited to these two embodiments.

[0058] The shielding cover 1 of the embodiment of the present application is provided with a plurality of connectors 3, and the plurality of connectors 3 are used to make line contact with the components to be connected (such as the circuit board 5) during assembly through the contact edge 30, thereby avoiding the problem of insufficient contact between the shielding cover 1 and the components to be connected (such as the circuit board 5) caused by manufacturing errors or assembly errors, effectively improving the EMC shielding effect of the shielding cover 1, and because of the use of the line contact method, effectively reducing the area occupied by the shielding cover 1 on the circuit board 5, thereby reducing the manufacturing and design costs of the circuit board 5. At the same time, the plurality of connectors 3 of the embodiment of the present application are arranged at intervals from each other, and each connector 3 is relatively independent, that is, when making line contact with, for example, the circuit board 5, they will not affect each other, further enhancing the contact between the plurality of connectors 3 and the circuit board 5.

[0059] [Example 1]

[0060] This embodiment exemplarily shows the first situation in which the connector 3 is in line contact with the circuit board 5 , that is, the corresponding contact edges 30 of all connectors 3 in the shielding cover 1 are in line contact with the circuit board 5 .

[0061] See also Figures 2 to 4The plurality of connectors 3 in the shielding cover 1 of the embodiment of the present application include a plurality of first connectors 31. For example, the bottom profile of the shielding cover body 2 of the embodiment of the present application is a rectangular structure, and the bottom of the shielding cover body 2 includes the following: Figure 2 The two sides indicated by the X direction, as well as Figure 2 The two sides indicated by the Y direction in the middle, a plurality of first connectors 31 are arranged around the four sides, and each first connector 31 includes the above-mentioned contact edge 30. On this basis, each contact edge 30 of the plurality of first connectors 31 can be in line contact with the circuit board 5.

[0062] It should be noted that, by way of example, Figure 2 The corresponding contact edges 30 of the plurality of first connecting members 31 on both sides indicated by the X direction extend along the Y direction; Figure 2 The corresponding contact edges 30 of the multiple connecting members 3 on both sides indicated by the Y direction extend along the X direction.

[0063] See also Figure 4 Combined with Figure 2 In a possible implementation, each first connector 31 includes an inclined portion (such as the third portion 313 described below), the inclined portion is inclined outwardly at an angle relative to the circuit board 5, and the inclined portion includes the contact edge 30. The embodiment of the present application does not impose any specific restrictions on the inclined portion, as long as the inclined portion can be inclined outwardly relative to the circuit board 5 so that the contact edge 30 is in line contact with the circuit board 5, it belongs to the protection scope of the embodiment of the present application.

[0064] Exemplarily, each first connecting member 31 includes a first portion 311, a second portion 312 and a third portion 313. One end of the first portion 311 is connected to the bottom of the shielding cover body 2, the other end of the first portion 311 is connected to one end of the second portion 312, the other end of the second portion 312 is connected to one end of the third portion 313, and the other end of the third portion 313 is provided with the contact edge 30. The inclined portion exemplarily includes the third portion 313.

[0065] In order to make it easier for the contact edge 30 to make linear contact with the circuit board 5, the first part 311, the second part 312, and the third part 313 are interconnected to form a bending structure. The embodiment of the present application does not limit the bending angle between the first part 311 and the second part 312, and the bending angle between the second part 312 and the third part 313. As long as the first connecting member 31 can be in linear contact with the circuit board 5, it falls within the protection scope of the embodiment of the present application.

[0066] See also Figures 5 to 7 Combined with Figure 2 and Figure 3The embodiment of the present application also provides an electronic device, including a circuit board 5, a first shielding member 6 and the above-mentioned shielding cover 1, wherein the shielding cover 1 is used to shield the first shielding member 6, and the first shielding member 6 is along a first direction (such as Figure 3 The first shielding member 6 is provided on the circuit board 5 along the first direction, at least a part of the plurality of first connecting members surrounds the first shielding member 6, and each corresponding contact edge 30 is in line contact with the circuit board 5.

[0067] In a possible implementation, the electronic device according to the embodiment of the present application further includes a metal shell 8 , which is the outer shell of the electronic device according to the embodiment of the present application, and the circuit board 5 is assembled in the metal shell 8 .

[0068] In a possible implementation manner, the first to-be-shielded member 6 includes a to-be-shielded component 62 . Figure 3 The shielded component 62 is exemplarily shown to be electrically connected to the ground plane of the circuit board 5 (eg Figure 3 The components 62 to be shielded are shielded inside the shielding cover body 2 along a first direction.

[0069] In a possible implementation, the first shielded member 6 further includes a first wiring harness 61. Exemplarily, the first wiring harness 61 is a signal line for transmitting a signal. Exemplarily, the first wiring harness 61 is further provided with a first connector 611 and a first connector 612. The first connector 611 is electrically connected to the ground plane of the circuit board 5 (e.g., Figure 3 and Figure 7 The first connector 612 is used as a connection terminal with an external device and is arranged at the bottom of the metal housing 8 (as shown in the Z1 direction). Figure 3 and Figure 7 The first connector 611 is also shielded inside the shielding cover body 2 along the first direction.

[0070] That is, the first wire harness 61 connected to the external device can be connected along the first direction (eg Figure 3 and Figure 7 The Z direction shown in FIG. 1 is connected to the circuit board 5 of the electronic device of the present application embodiment. That is, along the first direction, the first connector 611 (i.e. Figure 3 and Figure 7 The first wiring harness 61 is connected to the ground plane of the circuit board 5 in the Z1 direction, and the first connector 612 of the first wiring harness 61 is used to connect to an external device.

[0071] Continue reading Figures 5 to 7 Combined with Figure 2 and Figure 4In this embodiment, the plurality of first connectors 31 can surround the first wiring harness 61 and the shielded components 62, and at the same time, each contact edge 30 of the plurality of first connectors 31 is in line contact with the circuit board 5 (such as Figure 2 and Figure 4 As shown), at this time, the first wiring harness 61 and the components to be shielded 62 are accommodated in a relatively complete shielding space 4.

[0072] [Example 2]

[0073] The difference between this embodiment and the embodiment 1 is that the shielding cover 1 includes, in addition to the first connecting member 31, a plurality of second connecting members 32. The design of the second connecting members 32 is the same as that of the first connecting member 31, and each second connecting member 32 also includes the contact edge 30, but the only difference is that the length of the second connecting member 32 is greater than that of the first connecting member 31, so as to extend outside the circuit board 5, so that the second connecting member 32 can be in line contact with the metal shell 8. The embodiment 2 will be described in detail below.

[0074] See also Figure 8 , Fig.11 and Fig.12 , the plurality of connectors 3 in the shielding cover 1 of the present embodiment further include a plurality of second connectors 32. Exemplarily, Figure 8 , Fig.11 and Fig.12 The bottom profile of the shielding cover body 2 shown in the example is a rectangular structure, and the bottom of the shielding cover body 2 includes the following: Fig.11 The two sides indicated by the X direction, as well as Fig.11 The two sides indicated by the Y direction.

[0075] It can be seen that the plurality of first connecting members 31 are connected around three sides of the bottom of the shielding cover body 2, and the plurality of second connecting members 32 are connected at intervals. Fig.11 The second connectors 32 are configured to extend to the outside of the circuit board 5 and to the edge of the metal shell 8. Accordingly, each first connector 31 and each second connector 32 includes a contact edge 30.

[0076] The contact edge 30 of each first connector 31 is used for line contact with the circuit board 5, and the contact edge 30 of each second connector 32 is used for line contact with the metal shell 8. Based on this, the shielding cover body 2, multiple first connectors 31, and multiple second connectors 32 can form the shielding space 4.

[0077] See also Fig. 9 and Fig.10 , Fig. 9 An enlarged partial view of a portion of the first connecting member 31 is shown as an example. Fig.10The partially enlarged view of some second connecting members 32 is exemplarily shown. A plurality of first connecting members 31 and a plurality of second connecting members 32 are arranged at intervals.

[0078] In a possible implementation, a plurality of first connectors 31 and a plurality of second connectors 32 can be arranged at intervals of length L. Exemplarily, the length L can be selected within an open interval range of (0mm, 1.6mm), for example, the value of the length L can be 0.2mm, 0.75mm, 1mm, 1.59mm, etc., in which case the shielding cover can be applied to a shielding effect of 40db, and when it contacts the circuit board line, it can have a good shielding effect. Exemplarily, the length L can also be selected within an open interval range of (0mm, 16mm), for example, the value of the length L can also be 0.12mm, 4mm, 9.37mm, 15.56mm, etc., in which case the shielding cover can be applied to a shielding effect of 20db, and when it contacts the circuit board line, it can also have a good shielding effect.

[0079] See also Fig.13 and Fig.14 In a possible implementation manner, each second connecting member 32 also includes an inclined portion, which is inclined outward at an angle relative to the circuit board 5 , and includes the above-mentioned contact edge 30 .

[0080] In a possible implementation, each second connecting member 31 includes a fourth portion 321, a fifth portion 322, and a sixth portion 323. One end of the fourth portion 321 is connected to the bottom of the shielding cover body 2 (for example, Fig.11 The other end of the fourth portion 321 is connected to one end of the fifth portion 322, the other end of the fifth portion 322 is connected to one end of the sixth portion 323, and the other end of the sixth portion 323 is provided with the contact edge 30. The above-mentioned inclined portion exemplarily includes the sixth portion 323.

[0081] In order to make it easier for the contact edge 30 to make line contact with the metal shell 8, the fourth part 321, the fifth part 322 and the sixth part 323 are interconnected to form a bending structure. The embodiment of the present application does not limit the bending angle between the fourth part 321 and the fifth part 322, and the bending angle between the fifth part 322 and the sixth part 323. As long as the second connecting member 31 can be in line contact with the metal shell 8, it falls within the protection scope of the embodiment of the present application.

[0082] See also Fig.11 and Fig.12 Combined with Fig.15 and Fig.16 In this embodiment, the shielding cover 1 is used to shield the first shielding member 6 and the second shielding member 7. The first shielding member 6 is along a first direction (such as Figure 3 The Z direction shown in FIG. 1 is connected to the circuit board 5, and one end of the second shielding member 7 is connected to the ground plane of the circuit board 5 (such as Fig.11 The other end of the second shielding member 7 is used to move along the second direction (as indicated by the Z1 direction). Fig.11 E direction shown in the figure) is connected to the above-mentioned metal shell 8 which accommodates the circuit board 5.

[0083] Exemplarily, the second direction in the embodiment of the present application is a direction intersecting with the first direction. For example, the second direction may be Fig.11 The second direction may also be parallel to the Y direction shown in FIG. Fig.11 The X direction (ie, the width direction of the shielding cover 1 ) shown in the figure is parallel to the X direction (ie, the width direction of the shielding cover 1 ), and this embodiment of the present application does not impose any limitation on this.

[0084] It should be noted that Figures 11 to 16 Although only the shielded components in the first shielded member 6 are shown as examples, it can be understood that the shielding cover 1 in this embodiment can still shield the first wire harness arranged along the first direction (as described in Embodiment 1).

[0085] Based on this, the shielding cover body 2 is along the first direction (such as Fig.11 The Z direction (shown in the figure) is covered on the first shielded part 6 and the second shielded part 7, each contact edge 30 of the plurality of first connecting parts 31 is in line contact with the circuit board 5, and each contact edge 30 of the plurality of second connecting parts 32 is in line contact with the metal shell 8, so that the first shielded part 6 and the second shielded part 7 are accommodated in the above-mentioned shielding space 4.

[0086] See also Fig.12 , illustratively, in this embodiment, the metal shell 8 is also used to set the second shielding member 7, and the circuit board 5 is assembled in the metal shell 8. The metal shell 8 serves as the housing of the electronic device of the embodiment of the present application, and can be provided with a part of the second shielding member 7 (i.e., the second connector 712 of the second wiring harness 71 described later).

[0087] Continue reading Fig.11 and Fig.12 Combined with Fig.15 and Fig.16 In a possible implementation, the second shielded member 7 includes a second wiring harness 71. Exemplarily, the second wiring harness 71 is a signal line for transmitting signals. Exemplarily, the second wiring harness 71 is further provided with a second connector 711 and a second connector 712. The second connector 711 is electrically connected to the ground plane of the circuit board 5 (e.g. Fig.11 and Fig.12 The second connector 712 is a connection terminal for connecting to an external device. The second connector 712 is arranged on one side of the metal housing 8 along the second direction (such as Fig.11 The E direction shown in the figure is to the right).

[0088] It can be seen that in this embodiment, the plurality of first connectors 31 and the plurality of second connectors 32 can surround the first shielded member 6 and the second wiring harness 71, and at the same time, each contact edge 30 of the plurality of first connectors 31 is in line contact with the circuit board 5 (such as Fig.11 As shown), each contact edge of the plurality of second connecting members 32 is in contact with the edge line of the metal shell 8 (as shown Fig.11 , Fig.15 , Fig.16 As shown), at this time, the first shielded component 6 and the second wiring harness 71 are accommodated in a relatively complete shielding space 4.
