Technical Field
[0001] The utility model relates to the technical field of electromagnetic shielding, in particular to an easily detachable pressure-proof shielding cover. Background Art
[0002] Electronic products are ubiquitous in our lives, and they contain numerous electronic components. To prevent external electromagnetic waves from interfering with the product's internal circuitry and to reduce the outward radiation of internally generated electromagnetic waves, a shielding cover must be installed around the electronic components. Traditional shielding covers are secured to the motherboard via welding, but this method of attachment makes it difficult for staff to observe and inspect the electronic components within. Existing shielding covers consist of a shielding bracket and a shielding cover that fits atop the bracket. The bracket and cover are detachably connected, facilitating later circuit observation and repair. However, during use, the shielding bracket can be easily deformed by external forces, potentially contacting the internal circuitry or electronic components, causing them to malfunction or even damage them.

[0017] By adopting the above technical solution, the cooperation between the opposing engaging portions and the opposing matching portions can limit the swinging of the clamping member in the through hole, so that the shielding cover is more stably connected to the shielding bracket.
[0018] In summary, the present invention provides the following beneficial effects: The shielding bracket is provided with an anti-pressure block at the bottom to prevent deformation of the shielding bracket under stress, which could squeeze and damage electronic components.

[0027] The utility model is an easily detachable pressure-proof shielding cover, comprising a shielding bracket (1) and a shielding cover (2) covering the top of the shielding bracket (1), characterized in that an anti-pressure block (3) is provided at the bottom of the shielding bracket (1), and the anti-pressure block (3) is at the same height as the outer frame of the shielding bracket (1). Figure 1As shown, an anti-pressure block (3) is provided at the middle position of the bottom of the shielding bracket (1). The anti-pressure block (3) is equal in height to the frame of the shielding bracket (1), and supports the frame rod in the middle of the shielding bracket (1), which can effectively prevent the shielding bracket (1) from being deformed by force and squeezing the electronic components, thereby damaging the circuit or the electronic components. In this embodiment, the anti-pressure block (3) and the shielding bracket (1) form a groove in the middle position. A heat conduction device can be added to the groove to transfer heat from the bottom mainboard to the shielding cover, and then the shielding cover is connected to the heat dissipation device to achieve a rapid heat dissipation effect. The anti-pressure block (3) is made of metal material. The anti-pressure block (3) is equal in height to the frame of the bracket, and the anti-pressure block (3) is in direct contact with the bottom mainboard. The metal material has thermal conductivity and can transfer heat from the mainboard to the shielding cover to assist in heat dissipation. Moreover, since the metal material has a shielding effect on electromagnetic waves, the anti-pressure block (3) made of metal material can prevent the electronic components inside the shielding cover from interfering with each other.
[0028] The top of the shielding bracket (1) is provided with a clamping part (4), and the top of the shielding cover (2) is provided with a clamping part (5), and the clamping part (4) is engaged with the clamping part (5). The clamping part (4) includes a main body perpendicular to the bottom of the shielding bracket (1), a joint portion extending from one side of the main body toward the shielding bracket (1), and a support rib for limiting the deformation of the main body in a direction away from the joint portion, and the joint portion is used to clamp the main body and the clamping part (5); the clamping part (5) includes a main body perpendicular to the bottom of the shielding cover (2), a through hole located on one side of the main body, a mating part extending from one side of the main body toward the direction of the through hole, and a reinforcing rib for limiting the deformation of the main body in a direction away from the through hole; the clamping part (4) passes through the clamping part (5) through the through hole to the joint portion and abuts against the mating part. As Figure 1 and Figure 3 As shown, the shielding cover (2) and the shielding bracket (1) are connected together through the clamping parts (5) and the clamping parts (4) on the top thereof respectively. When observing or repairing the circuit at a later stage, it is only necessary to tilt the clamping parts (4) toward the other side of the clamping parts (5) to separate the shielding bracket (1) from the shielding cover (2); after observing or repairing the circuit, the clamping parts (4) on the shielding cover (2) are aligned with the clamping parts (5) on the shielding bracket (1) and force is applied downwards to make the joint parts and the matching parts abut against each other, and the shielding cover (2) and the shielding bracket (1) can be reconnected, which is convenient for installation and disassembly and convenient for inspection and repair of the circuit.
[0029] The side of the joint part facing away from the main body is provided with a guiding slope, and the side of the matching part facing away from the main body is provided with a guiding slope, and the guiding slopes are parallel to each other. The bottom of the joint part is provided with an abutting surface intersecting with the guiding slope, and the top of the matching part is provided with an abutting surface intersecting with the guiding slope and abutting against the abutting surface. Figure 3As shown, when the clamping member (4) passes through the clamping member (5) through the perforation, the guiding bevel and the guide bevel move relative to each other. Since the two bevels are parallel to each other, the clamping member (4) can pass through the perforation more easily. Then, the abutting surface on the guiding bevel and the abutting surface of the matching portion abut against each other in the upper and lower directions, thereby fixing the shielding cover (2) and the shielding bracket (1) together.
[0030] The clamping member (4) and the clamping member (5) are made of elastic material. The clamping member (4) is respectively arranged at the top of the shielding bracket (1) in opposite directions; the clamping member (5) is respectively arranged at the top of the shielding cover (2) in opposite directions; the clamping member (4) and the clamping member (5) are positioned correspondingly. Figure 2 As shown in FIG3 , in this embodiment, four clamping parts (4) are arranged on the four sides of the top of the shielding bracket (1), and four clamping parts (5) are arranged on the four sides of the top of the shielding cover (2). The clamping parts (4) and the clamping parts (5) are positioned correspondingly. The clamping parts (4) can be restricted from swinging back and forth in the perforation by the cooperation of the opposing joint parts and the opposing matching parts, so that the shielding cover (2) can be more stably connected to the shielding bracket (1). During the clamping process, the clamping parts (4) and the clamping parts (5) will bend to the other side of each other when subjected to force. The use of elastic material can prevent the clamping parts (4) and the clamping parts (5) from being bent and damaged by force. The elastic material has a certain elasticity, making it easier to clamp or separate the shielding bracket (1) and the shielding cover (2).
[0031] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
