Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding covers, in particular to a quickly detachable electromagnetic shielding cover. Background Art

[0002] Electromagnetic shielding is a device used to prevent electromagnetic interference. It is usually made of metal materials and can prevent the spread of electromagnetic energy, thereby achieving electromagnetic shielding. It can prevent the influence of external electromagnetic interference, and also prevent the influence of electromagnetic interference generated by itself on the outside world. It has a wide range of applications, including but not limited to electronic products, communication equipment, medical equipment, aerospace and other fields. In these fields, electromagnetic shielding can effectively suppress electromagnetic interference and improve the performance and reliability of equipment.

[0003] Most of the existing electromagnetic shielding covers are stamped out of a whole iron piece, which is welded to the circuit board to cover the electronic components that need to be shielded, thereby playing a shielding role. However, when it is necessary to repair the electronic components in the shielding cover, the electromagnetic shielding cover needs to be completely disassembled. During the disassembly process, a large force needs to be applied to the electromagnetic shielding cover and the circuit board to separate the two from each other. During the operation, the force applied to the shielding cover will damage the shielding cover, and it is also easy to damage the structure of the circuit board. Utility Model Content

[0024] The utility model provides an electromagnetic shielding cover which can be quickly disassembled.

[0025] In an embodiment of the utility model, a quickly detachable electromagnetic shielding cover, such as Figure 1As shown, it includes a shielding frame 2 and a cover body 1 buckled on the shielding frame 2, the shielding frame 2 is welded on the circuit board, and the cover body 1 and the shielding frame 2 are buckled in a manner that the cover body 1 is directly sleeved on the shielding frame 2 to cover the shielding frame 2. In order to fix the cover body 1 on the shielding frame 2 and realize the function of quick disassembly, a locking column 4 is penetrated on the cover body 1, and a mounting seat 3 is provided on the shielding frame 2. When the cover body 1 is buckled on the shielding frame 2, the locking column 4 is inserted into the mounting seat 3 and rotated to engage. The structure can be that an annular clamping groove is provided on the inner wall of the mounting seat 3, and a pressing slot connecting the top of the mounting seat 3 and the clamping groove is provided. A clamping block is provided on the locking column 4, and the clamping block is inserted into the pressing slot into the clamping slot. The clamping block is clamped in the clamping slot by rotation, thereby realizing the rotational connection between the locking column 4 and the mounting seat 3. When the cover body 1 needs to be removed, the locking column 4 can be rotated to quickly separate the cover body 1 and the shielding cover, thereby realizing the rapid disassembly of the cover body 1 without any damage to the cover body 1.

[0026] Preferably, if Figures 1 to 3 As shown, in order to facilitate the removal of the cover body 1 from the shielding cover, an elastic member 5 is arranged in the mounting seat 3. When the locking column 4 is rotated and engaged with the mounting seat 3, the locking column 4 presses and abuts against the elastic member 5, so that the elastic member 5 is in a contracted state. At this time, the elastic member 5 applies pressure to both the locking column 4 and the mounting seat 3, so that the two are more tightly combined. When the locking column 4 and the mounting seat 3 are released from the engaged state, that is, when the engaging block is rotated to the position of the pressing slot, the elastic member 5 returns to its original state to pop out the locking column 4, thereby separating the cover body 1 from the shielding frame 2. The elastic member 5 here can be a leaf spring or a torsion spring.

[0027] Alternatively, if Figures 2 to 3 As shown, a locking groove 32 and a release groove 31 are provided on the inner wall of the mounting seat 3, which are interconnected and set at an angle. The release groove 31 is connected to the top of the mounting seat 3.

The connection angle of the release groove 31 and the locking groove 32 can be vertical or acute angle, which is not described here. A clamping block 41 is convexly provided on the outer wall of the locking column 4. When the locking column 4 is rotated and engaged with the mounting seat 3, the clamping block 41 rotates to the locking groove 32 through the release groove 31 to engage with the locking column 4. When the locking column 4 is separated from the mounting seat 3, the clamping block 41 slides out through the release groove 31.

[0028] Optionally, a stop plate 42 is provided at one end of the locking column 4 , and the stop plate 42 abuts against the top of the cover body 1 .

[0029] Optionally, in order to facilitate the rotation of the locking column 4, the stop plate 42 is provided with a straight groove 421, and the locking column 4 can be rotated by clamping it in the straight groove 421 with a card, a maintenance tool or a fingernail.

[0030] Optionally, to prevent the elastic member 5 from falling out of the mounting seat 3, a limit block 33 is further provided on the inner wall of the mounting seat 3. The limit block 33 is provided at the bottom of the inner wall of the mounting seat 3. One end of the elastic member 5 is clamped on the limit block 33. The elastic member 5 is a spring, and the limit block 33 directly clamps the bottom of the spring.
