Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to a shielding cover in which a grounding component is welded to the shielding cover frame, and at least a portion of the grounding component can abut against the side of the electronic component to ground the electronic component, thereby providing ground protection for the electronic component. Background Technology

[0002] Shielding covers are mainly used in electronic products such as mobile phones and GPS devices to prevent electromagnetic interference and to shield electronic components on PCB boards (Printed Circuit Boards).

[0003] Currently, traditional shielding covers only serve a basic protective function, which includes at least: preventing electromagnetic interference (for example, shielding covers can shield electronic components on PCBs), preventing electronic components from being damaged by external forces (i.e., most electronic components are very fragile and therefore easily damaged by external forces; while shielding covers are generally made of metal, so they usually have excellent toughness and impact resistance, thus effectively preventing electronic components from being damaged by external forces), and preventing electronic components from being damaged by stress (the shielding cover has a supporting function, which can prevent stress factors from damaging electronic components).

[0004] In existing technologies, there is no contact between the traditional shielding cover and the electronic components, resulting in the electronic components not being grounded. This can cause damage to the electronic components due to discharge, short circuits, and other reasons, thereby reducing the reliability of the entire PCB board. Utility Model Content

[0054] Please see Figures 1-5 The shield 100 is disposed on a PCB board 200 having a plurality of electronic components 2001, and can cover at least one electronic component 2001.

[0055] Generally speaking, existing shielding covers can protect the electronic components they cover. For example, existing shielding covers can shield electronic components to prevent electromagnetic interference from adversely affecting them. Furthermore, existing shielding covers are usually made of metal, giving them excellent toughness and impact resistance, thus effectively preventing damage to electronic components caused by external forces. Additionally, existing shielding covers can also serve as support structures, increasing the mechanical strength of the PCB board and preventing damage to electronic components due to stress. In addition to the above-mentioned protective functions, this shielding cover 100 can also provide grounding protection to prevent damage to the electronic component 2001 due to the lack of grounding.

[0056] The aforementioned shield 100 includes: a shield frame 1 and several grounding components 2.

[0057] The shielding frame 1 is fixedly installed on the PCB board 200, and the shielding frame 1 forms an accommodating space 1001 inside.

[0058] In addition, at least one electronic component 2001 is housed inside the housing space 1001 so that at least one electronic component 2001 is covered.

[0059] In addition, a through hole 111 is provided at one end of the shielding frame 1 away from the PCB board 200, and the through hole 111 is connected to the receiving space 1001 so that a part of the electronic component 2001 housed inside the receiving space 1001 extends through the through hole 111 to the outside of the receiving space 1001.

[0060] It should be noted that several grounding components 2 are welded to the shielding frame 1 along the circumferential edge of the through hole 111 and are located outside the receiving space 1001; at least a portion of the grounding components 2 can abut against the circumferential side of the electronic component 2001 housed inside the receiving space 1001.

[0061] In some embodiments, such as Figures 1-3 As shown, the shielding frame 1 includes: a mounting plate 11 and several upright plates 12.

[0062] Specifically, several upright plates 12 protrude from the surface of the mounting plate 11; through holes 111 are formed on the mounting plate 11, and several grounding components 2 are welded to the mounting plate 11.

[0063] To further explain, the end of the upright plate 12 away from the mounting plate 11 abuts against the surface of the PCB board 200; the mounting plate 11 and several upright plates 12 enclose and form an accommodating space 1001.

[0064] In some embodiments, combined with Figure 1 and Figure 3 It can be seen that each of the several upright plates 12 is formed by stamping at least a portion of the mounting plate 11, and is an integral structure with the mounting plate 11.

[0065] In some embodiments, according to Figure 1 and Figure 2 It is known that each electronic component 2001 has a mounting portion 2002 and a contact portion; one end of the mounting portion 2002 abuts against the surface of the PCB board 200, and the other end abuts against the contact portion.

[0066] In this embodiment, the end of the contact portion away from the mounting portion 2002 extends through the through hole 111 toward the outside of the receiving space 1001.

[0067] In some embodiments, by Figures 1-4 It is understood that the through hole 111 has a shape and size that are adapted to the contact portion of the electronic component 2001 housed inside the housing space 1001.

[0068] In some embodiments, refer to Figure 4 and Figure 5 It can be seen that the grounding component 2 includes: a base plate 21 and several grounding springs 22.

[0069] The base plate 21 is welded to the mounting plate 11, and several grounding springs 22 are connected to the base plate 21.

[0070] In addition, at least a portion of the grounding spring 22 may abut against the side of the contact portion of the electronic component 2001 housed inside the receiving space 1001.

[0071] In addition, several grounding springs 22 are formed by at least partial stamping of the base plate 21, and are integral with the base plate 21.

[0072] In some embodiments, combined with Figure 4 and Figure 5 It is known that the grounding spring 22 includes: a first bending portion 221, a first elastic arm 222, a second bending portion 223, a second elastic arm 224, a third bending portion 225, and a third elastic arm 226.

[0073] Specifically, one end of the first bent portion 221 is connected to the side of the base plate 21 near the edge of the through hole 111, and the other end is connected to the first elastic arm 222.

[0074] It is understood that the end of the first elastic arm 222 away from the first bend 221 extends away from the bottom plate 21 and away from the edge of the through hole 111, and is connected to the second bend 223.

[0075] It should be noted that the end of the second bend 223 that is away from the first elastic arm 222 is connected to the second elastic arm 224.

[0076] To further explain, the end of the second elastic arm 224 away from the second bend 223 extends away from the base plate 21 and close to the edge of the through hole 111, and is connected to the third bend 225.

[0077] In this embodiment, the end of the third bend 225 away from the second elastic arm 224 is connected to the third elastic arm 226; the end of the third elastic arm 226 away from the third bend 225 extends toward the bottom plate 21 and toward the edge of the through hole 111.

[0078] In some embodiments, such as Figure 4 and Figure 5 As shown, at least a portion of the first elastic arm 222, at least a portion of the second bent portion 223, and a portion of the second elastic arm 224 may abut against the contact side of the electronic component 2001 housed inside the receiving space 1001.

[0079] In some embodiments, according to Figure 4 and Figure 5It can be seen that the first elastic arm 222, the second elastic arm 224 and the third elastic arm 226 are all straight; the first bending part 221, the second bending part 223 and the third bending part 225 are all arc-shaped.

[0080] The first bending portion 221 has a first arc surface 2211 and a second arc surface 2212; the second bending portion 223 has a third arc surface 2231 and a fourth arc surface 2232; and the third bending portion 225 has a fifth arc surface 2251 and a sixth arc surface 2252.

[0081] In addition, the first arc surface 2211 has a first radial dimension, and the second arc surface 2212 has a second radial dimension; the third arc surface 2231 has a third radial dimension, and the fourth arc surface 2232 has a fourth radial dimension; the fifth arc surface 2251 has a fifth radial dimension, and the sixth arc surface 2252 has a sixth radial dimension.

[0082] Furthermore, the first radial dimension is smaller than the second radial dimension; the third radial dimension is smaller than the fourth radial dimension; and the fifth radial dimension is smaller than the sixth radial dimension.

[0083] In some embodiments, please refer to Figures 1-5 The first arc surface 2211 is connected to the first surface 211 of the base plate 21, and the second arc surface 2212 is connected to the second surface 212 of the base plate 21.

[0084] It should be noted that the fifth arc surface 2251, the third arc surface 2231 and the first arc surface 2211 are located on the same side, and the sixth arc surface 2252, the fourth arc surface 2232 and the second arc surface 2212 are located on the same side.

[0085] Specifically, the first surface 211 and the second surface 212 are two opposing surfaces of the base plate 21 in the thickness direction, and the second surface 212 abuts against the surface of the PCB board 200.

[0086] It is understood that the grounding spring 22 has an elastic force, and this elastic force can limit the movement of the second bent portion 223 toward the base plate 21; wherein, when the grounding spring 22 provides the above-mentioned elastic force, at least a portion of the first elastic arm 222 of the grounding spring 22, at least a portion of the second bent portion 223, and a portion of the second elastic arm 224 can be tightly attached to the side of the contact portion 2003 to improve the grounding reliability of the electronic component 2001, thereby providing more reliable grounding protection for the electronic component 2001, so as to avoid damage to the electronic component 2001 due to discharge, short circuit, etc., and thus improve the reliability of the entire PCB board 200.

[0087] In summary, the shielding cover provided by this utility model embodiment, through the structural design of incorporating a grounding component, with the grounding component welded along the edge of the through-hole to the shielding cover frame and abutting against the side of the electronic components housed within the containment space, grounds the electronic components. This allows the shielding cover to not only prevent electromagnetic interference and damage to the electronic components from external forces, but also provide grounding protection, thus preventing damage to the electronic components due to lack of grounding and improving the overall reliability of the PCB board. Therefore, the shielding cover provided by this utility model embodiment has a certain novelty compared to traditional shielding covers.

[0088] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
