Description

Technical Field

[0001] This utility model belongs to the field of mobile phone motherboard technology, specifically relating to a shielding shell for edge signal lines of a mobile phone motherboard with foldable protective wings. Background Technology

[0002] The motherboard is the most crucial circuit board inside a mobile phone, essentially acting as its "nerve center." It is responsible for connecting and controlling the coordinated operation of all electronic components. When operating, the motherboard faces electromagnetic interference (EMI) and physical risks, and a shielding shell is the core solution to these problems.

[0003] A mobile phone shield is a device that uses a shield to surround the interference sources of components, circuits, assemblies, cables, or the entire system, preventing the outward spread of interfering electromagnetic fields. The principle of a mobile phone shield is to surround the interference sources of components, circuits, assemblies, cables, or the entire system with a shield to prevent the outward spread of interfering electromagnetic fields, and to surround the receiving circuits, equipment, or systems with a shield to prevent them from being affected by external electromagnetic fields.

[0004] Chinese patent CN217486516U discloses a mobile phone motherboard with shielding covers. The specification states that most existing mobile phone motherboards do not come with built-in shielding covers and require adhesive to fix them to the motherboard, which is inconvenient for disassembly and lacks strong stability and anti-interference capabilities. Therefore, we propose a mobile phone motherboard with shielding covers. Bolts pass through threaded holes to fix the first, second, and third shielding covers to the motherboard body. Springs are also installed inside the threaded holes to absorb shock and prevent the shielding covers from falling off and the motherboard body from being damaged during use due to vibration. Disassembly and repair are also extremely convenient, greatly improving the practicality of the motherboard.

[0005] In the aforementioned application, the shielding cover is installed on the motherboard using bolts. Since the shielding cover is small, the corresponding bolts are also small. This makes it difficult to quickly remove the shielding cover during later motherboard repairs, causing inconvenience to operators. Utility Model Content

[0006] The purpose of this invention is to provide a shielding shell for the edge signal lines of a mobile phone motherboard with foldable protective wings, so as to solve the problem that the existing mobile phone motherboard shielding covers are not easy to disassemble quickly.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile phone motherboard edge signal line shielding shell with foldable protective wings includes a motherboard body. Multiple fixing frames are fixedly connected to the end face of the motherboard body. Multiple first circular holes are opened on the end face of the fixing frames. First insertion posts are slidably connected to the inner walls of the multiple first circular holes. The shielding shell body is fixedly connected to the top of the multiple first insertion posts.

[0009] Preferably, the surface of the motherboard body has multiple notches, and the end face of the motherboard body has multiple capacitor areas.

[0010] Preferably, the number of fixed frames is four, the number of capacitor regions is four, and the four capacitor regions are respectively located inside the four fixed frames.

[0011] Preferably, the fixed frame has two second circular holes on both sides, and two second posts are slidably inserted into the inner walls of the four second circular holes. Springs are fixedly connected to the surfaces of the four second posts, and the springs are fixedly connected to the inner walls of the second circular holes. The arc surface of the first post has a third circular hole that matches the second post.

[0012] Preferably, the cross-sectional shape of the end of the second insert away from the spring is semi-circular.

[0013] Preferably, the first circular hole is connected to the second circular hole, and the size of the inner wall of the first circular hole is adapted to the size of the first insertion post.

[0014] Preferably, four buffer pads are fixedly connected to the end face of the fixed frame. The buffer pads are made of rubber, and the positions of the four buffer pads correspond to the positions of the four first circular holes.

[0015] Preferably, the shielding housing body is made of metal.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model manages multiple capacitor areas by dividing them into multiple shielded shell bodies, which can modularly shield the motherboard, avoid signal crosstalk between different functional modules, protect sensitive signal lines at the edge of the motherboard, effectively suppress electromagnetic radiation leakage, and reduce abnormal operation of components caused by interference.

[0018] 2. This utility model uses the compression of the second insertion post by the first insertion post and the elastic force of the spring to quickly insert the second insertion post into the third round hole, thereby stabilizing the entire shielding shell body. In the later disassembly, the operator only needs to pull the shielding shell body upward with force to quickly disassemble the shielding shell body, saving a lot of time.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 As shown, this utility model provides a shielding shell for the edge signal line of a mobile phone motherboard with foldable protective wings, including a motherboard body 1. Multiple fixing frames 2 are fixedly connected to the end face of the motherboard body 1. Multiple first circular holes 4 are opened on the end face of the fixing frames 2. First inserts 6 are slidably connected to the inner walls of the multiple first circular holes 4. The shielding shell body 3 is fixedly connected to the top of the multiple first inserts 6.

[0027] In this embodiment, during disassembly and maintenance, the operator only needs to use a tool to pull the shielding shell body 3 upward, so that the first insertion post 6 moves upward and the second insertion post 8 is disengaged from the interior of the third round hole 7 to achieve the effect of quick disassembly.

[0028] In an optional embodiment: the surface of the motherboard body 1 is provided with a plurality of notches 101, and the end face of the motherboard body 1 is provided with a plurality of capacitor areas 102.

[0029] It should be noted that by dividing and managing multiple capacitor areas 102 through multiple shielded housing bodies 3, the motherboard can be modularly shielded, avoiding signal crosstalk between different functional modules, and protecting sensitive signal lines at the edge of the motherboard, effectively suppressing electromagnetic radiation leakage and reducing abnormal operation of components due to interference.

[0030] In an optional embodiment: the number of fixed frames 2 is four, the number of capacitor regions 102 is four, and the four capacitor regions 102 are respectively located inside the four fixed frames 2.

[0031] In an optional embodiment: two second circular holes 5 are opened on both sides of the fixed frame 2, and two second inserts 8 are slidably inserted into the inner walls of the four second circular holes 5. Springs 9 are fixedly connected to the surfaces of the four second inserts 8. Springs 9 are fixedly connected to the inner walls of the second circular holes 5. A third circular hole 7 that matches the second insert 8 is opened on the arc surface of the first insert 6.

[0032] It should be noted that the first circular hole 4 is connected to the second circular hole 5. The inner wall size of the first circular hole 4 is adapted to the size of the first insertion post 6. When the operator aligns the first insertion post 6 on the shielding shell body 3 with each of the first circular holes 4 and inserts it, the first insertion post 6 will press against the second insertion post 8. Since the cross-section of the pressed end of the second insertion post 8 is semi-circular, the second insertion post 8 will slide. At this time, the spring 9 will be in a compressed state until the third circular hole 7 is flush with the second insertion post 8. Then the compressed spring 9 will rebound, allowing the second insertion post 8 to be inserted into the third circular hole 7, thus stabilizing the shielding shell body 3. In the later disassembly, the operator only needs to pull the shielding shell body 3 upward with force to quickly disassemble the shielding shell body 3, saving a lot of time.

[0033] In an alternative embodiment, the cross-sectional shape of the end of the second post 8 away from the spring 9 is semi-circular.

[0034] It should be noted that the cross-sectional shape of the end of the second insert 8 away from the spring 9 is semi-circular, which allows the second insert 8 to slide when it is squeezed.

[0035] In an optional embodiment: four buffer pads 10 are fixedly connected to the end face of the fixed frame 2. The buffer pads 10 are made of rubber material, and the positions of the four buffer pads 10 correspond to the positions of the four first circular holes 4 respectively.

[0036] It should be noted that the buffer pad 10 plays a buffering role. By filling the gap between the shielding shell body 3 and the fixed frame 2 with elastic material, it absorbs the impact force when the mobile phone is dropped or pressed. It is especially suitable for densely stacked motherboard areas. At the same time, it can also increase the friction between the shielding shell body 3 and the fixed frame 2 to a certain extent, thereby improving stability.

[0037] In an optional embodiment: the shielding housing body 3 is made of metal.

[0038] It should be noted that it has good electrical conductivity and flexibility.

[0039] The working principle of this utility model is as follows: In use, the operator aligns the first insertion post 6 on the shielding shell body 3 with each of the first round holes 4 and inserts it. The first insertion post 6 will press against the second insertion post 8. Since the cross-section of the end of the second insertion post 8 that is pressed is semi-circular, the second insertion post 8 will slide. At this time, the spring 9 will be in a compressed state until the third round hole 7 is flush with the second insertion post 8. The compressed spring 9 will then rebound, allowing the second insertion post 8 to be inserted into the third round hole 7, thus stabilizing the shielding shell body 3. During disassembly and maintenance, the operator only needs to use a tool to pull the shielding shell body 3 upward, so that the first insertion post 6 moves upward and the second insertion post 8 is disengaged from the interior of the third round hole 7, thus achieving the effect of quick disassembly.
