In the embodiment provided by the present disclosure, the partition bracket 3 may be configured in a special shape, to partition the top plate 1 into at least two regions that are not communicated with each other, for example, referring to fig. 1, the partition bracket 3 includes a first bracket and a second bracket connected to each other, the connection frame 2 is formed by connecting a plurality of connection rods end to end in sequence, wherein, two ends of the first bracket respectively lean against two connecting rods which are oppositely arranged on the connecting frame 2, one end of the second bracket is connected with the middle part of the first bracket, the other end of the second bracket is abutted against one connecting rod adjacent to the connecting rod, through the design, the top plate 1 can be divided into three areas which are not communicated with each other, further, when the shield is assembled with the circuit board 100, the circuit board 100 can be divided into three regions that are not in communication with each other, so that there is no electromagnetic interference between the electronic components in the three regions.

In the embodiments provided in the present disclosure, the separation bracket 3 may include a fixing plate and a supporting plate, the fixing plate being connected with the supporting plate and the fixing plate and the supporting plate being at an angle to each other. For example, in the embodiment shown in fig. 3, the first bracket includes a first fixing plate 31 and a first support plate 32, the first fixing plate 31 is connected to the first support plate 32, and the first support plate 32 is bent from one side of the first fixing plate 31 to be at an angle with the first fixing plate 31. Here, the first fixing plate 31 and the first support plate 32 may be connected to each other perpendicularly by a welded connection, and further, the first fixing plate 31 and the first support plate 32 may be connected to each other at any suitable angle, and the disclosure is not particularly limited thereto. In the embodiment shown in fig. 3, the second bracket includes a second fixing plate 33 and a second supporting plate 34, the second fixing plate 33 is connected to the first supporting plate 32 and the second supporting plate 34 is bent from one side of the second fixing plate 33 to be angled with respect to the second fixing plate 33.

In the specific embodiment provided by the present disclosure, the fixing plate is connected to the top plate 1 by spot welding. In this embodiment, the first fixing plate 31 and the second fixing plate 33 are respectively spot-welded to the top plate 1, so that the first fixing plate 31 and the second fixing plate 33 can be stably connected to the top plate 1, and the first fixing plate 31 and the second fixing plate 33 can be separated from the top plate 1 when maintenance is required. The number of welding points between the first fixing plate 31 and the second fixing plate 33 and the top plate 1 may be determined according to a force value required to tear the top plate 1 from the connection frame 2, which is not particularly limited by the present disclosure.

In the embodiments provided in the present disclosure, for maintenance, the shielding cover may be provided with a weak portion so as to expose the electronic components on the circuit board 100, and thus maintain the electronic components.

In one embodiment, the top panel 1 is provided with a weakened portion, by which the top panel 1 can be divided into a tear area and a reserved area, the tear area is a portion that needs to be removed or lifted up for maintenance, and the reserved area is a portion that is connected to the connecting frame 2. The electronic component covered by the tearing area can be exposed by removing or tilting the tearing area, so that the electronic component can be maintained. In this case, the weak portion may be formed by punching on the surface of the top plate 1, so that the thickness of the weak portion is smaller than that of the top plate 1, and therefore, the weak portion is an easy-to-handle portion, and by breaking the connection between the weak portion and the top plate 1, the tear region can be separated from the remaining region to expose the electronic component covered by the tear region.

To further facilitate maintenance, the shield is provided with a recess 4, which recess 4 is adjacent to the weakening, and the torn area is removed or tilted by inserting a tool (e.g. a screwdriver or the like) into the recess 4 when maintenance is required. In this case, the groove 4 may be located on the top plate 1 and may also be located on the connection frame 2, which is not particularly limited by the present disclosure.

In another embodiment, a weak portion is formed at the connection position of the top plate 1 and the connection frame 2, in which case the top plate 1 can be integrally removed or tilted from the connection frame 2 to expose the electronic components on the whole circuit board 100. Here, the weak portion may be formed by forming the top plate 1 by punching such that the thickness of the weak portion is less than that of the top plate 1, and thus, the weak portion is an easy-to-handle portion, and the top plate 1 can be integrally removed or tilted from the connection frame 2 by damaging the connection between the weak portion and the top plate 1 or the connection between the weak portion and the connection frame 2, at which time the connection frame 2 and the partition bracket 3 remain fixed to the PCB board 100, as shown in fig. 5.

In order to further facilitate maintenance, the shielding case is provided with a groove 4, the groove 4 is adjacent to the weak part, when maintenance is needed, a tool (such as a screwdriver and the like) is inserted into the groove 4 to tilt the top plate 1, so that the top plate 1 is torn off from the connecting frame 2, and the operation is simple and labor-saving. As shown in fig. 2, 4 and 5, the groove 4 may be provided at one corner portion of the shield case, so that one corner of the top plate 1 can be tilted by a tool and then an operation of integrally tearing the top plate 1 from the coupling frame 2 is performed.

It should be explained here that, in the product testing stage, the product needs to be tested many times, when the product needs to be maintained, the electronic component on the circuit board 100 can be maintained by tearing the top plate 1 off the connecting frame 2, and when the product is reused, the top plate 1 can be replaced by sticking the insulating sheet on the connecting frame 2, so that the electromagnetic interference shielding effect can be achieved. In the product application, when a failure or damage occurs, the product that has been damaged is replaced with a new one, and therefore, after the top panel 1 is torn off, there is no need to consider the problem of the top panel 1 being re-connected to the connection frame 2.

In the embodiments provided in the present disclosure, referring to fig. 1, 2 and 4, a heat dissipation window 11 may be disposed on the top plate 1, and a copper sheet for heat dissipation may extend into the inside of the shielding case from the heat dissipation window 11 to contact the electronic component, so that heat generated by the electronic component can be dissipated through the heat dissipation window 11.

In the embodiment provided by the present disclosure, the connection frame 2 may be fixed to the circuit board 100 by welding, and there is no gap between the connection frame 2 and the circuit board 100 by this connection manner, so that no abnormal sound is generated between the connection frame 2 and the circuit board 100 when a shock is applied. Referring to fig. 1, 2, 4 and 5, the connection frame 2 may be a rectangular shape formed by connecting a plurality of connection rods end to end in sequence. Further, the number of the connection rods connecting the frames 2 may also be three, five, six, etc., and the present disclosure is not particularly limited. In some embodiments, the connection frame 2 may be connected to the circuit board 100 by adhesion, which is not particularly limited by the present disclosure.
