DETAILED DESCRIPTION
[0042] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawing, the utility model is further detailed.
[0043] Embodiment 1: please refer to Figures 1 to 7 As shown in the drawing, the embodiment provides a kind of assembled electromagnetic shielding plate, comprising: at least two shielding plates 1 suitable for assembling cooperation;Here, each shielding block can be selected to adopt regular shape body, for example, cuboid structure, so that at least two shielding blocks can be assembled into the side plate or door plate required by large size shielding chamber or shielding cabinet.
[0044] On the basis of the above structure, for the assembling mode between the adjacent shielding plates 1, the end portions of the two shielding plates 1 in the embodiment are provided with shielding joint assemblies. In the case of an optional condition, each shielding joint assembly comprises a metal blade 2 provided on one of the shielding plates 1 and a blade slot 32 provided on the other shielding plate 1 and adapted to the metal blade 2. It should be noted that, in combination with the different thicknesses of the shielding plates 1 applied in different scenarios, the number of the metal blades 2 and the blade slots 32 corresponding to each shielding joint assembly is also different. For example, for the relatively thin shielding plates 1, only one set of the metal blades 2 and the blade slots 32 can be provided, while for the relatively thick shielding plates 1, two or more sets of the metal blades 2 and the blade slots 32 can be provided. The embodiment is not limited absolutely. The following embodiment will be described in detail only in the case of one set of the metal blades 2 and the blade slots 32.
[0045] Based on the above, it is also necessary to point out that, for each shielding plate 1, in order to meet the use requirements of the shielding assembly, the end portion of each shielding plate 1 for splicing with other shielding plates 1 is provided with a recessed assembly cavity 11, which is mainly used for setting the shielding assembly.
[0046] On the basis of the above structure, it is further necessary to point out that the assembly cavity 11, the metal blade 2 and the blade slot 32 in each shielding plate extend along the length direction of the end portion of each shielding plate 1 for splicing with other shielding plates 1.
[0047] Furthermore, each metal blade 2 comprises a metal base plate 21 for fixed connection with the bottom wall of the assembly cavity 11 of the shielding plate 1, and a blade portion 22 connected with the metal base plate 21; wherein the blade portion 22 and the metal base plate 21 form a T-shaped body. When the shielding plate 1 is made of metal material, the metal base plate 21 can be optionally welded directly to the shielding plate 1. When a non-metal shielding plate 1 is used, the metal base plate 21 can be fastened and assembled into the assembly cavity 11, for example but not limited to, by means of a screw with a conductive gasket, wherein the conductive gasket has a basic shielding function. The material of the metal blade 2 can be, for example but not limited to, brass plate or red copper plate, which has good shielding effect.
[0048] Based on the above structure, it is necessary to point out that the blade portion 22 at least partially extends outside the assembly cavity 11; and the extending direction of the blade portion 22 is perpendicular to the length direction of the end portion of the shielding plate 1 for splicing with other shielding plates 1.
[0049] Next, it is to be explained that the knife slot 32 of the embodiment is formed between a pair of metal spring leaves 31 with protruding portions; and a pair of metal spring leaves 31 are fixed in the assembly cavity 11 of the shielding plate 1 by the metal support 4. In this regard, considering the convenience of assembly, in an alternative implementation, a pair of metal spring leaves 31 are adapted to be embedded into the assembly cavity 11 by forming an integral spring leaf through a connecting portion.
[0050] In order to meet the assembly requirements of the integral spring leaf, the metal support 4 used in the embodiment includes a metal main plate 41 for fixed connection with the bottom wall of the assembly cavity 11, and a pair of metal fin plates 42 connected with the metal base plate 21; a U-shaped shape is formed by the pair of metal fin plates 42 and the metal base plate 21. When the shielding plate 1 is made of metal material, the metal main plate 41 here can be optionally fixed to the shielding plate 1 by direct welding; when a non-metal shielding plate 1 is used, the metal main plate 41 can be fastened into the assembly cavity 11, for example but not limited to, by means of a conductive gasket cooperating with a screw, wherein the conductive gasket has the most basic shielding function. The material of the metal support 4 here can be, for example but not limited to, electromagnetic aluminum alloy, which is extruded by high-temperature heating mechanism mold, has lower manufacturing cost, and has good shielding effect.
[0051] In more detail, the integral spring leaf includes a spring leaf bottom plate 33 for adhering to the metal main plate 41 and a pair of spring leaf side plates 34 connected with the spring leaf bottom plate 33, and each spring leaf side plate 34 is formed with a protruding portion adapted to abut against the knife portion 22 of the metal knife 2. In addition, the end of each spring leaf side plate 34 away from the spring leaf bottom plate 33 is also provided with an outwardly turned inverted U-shaped buckle 35; each inverted U-shaped buckle 35 is adapted to be buckled on the end of the metal fin plate 42 away from the metal base plate 21. Under this structure, considering further improving the firmness of the cooperation structure formed by the integral spring leaf and the metal support 4, for the spring leaf bottom plate 33 and the spring leaf side plate 34, the end surface for adhering to the metal support 4 can be coated with glue, so that the integral spring leaf not only relies on its own metal elasticity to cooperate with the metal support 4, but also strengthens the firmness of the cooperation structure formed by the glue.
[0052] In addition, it is also necessary to explain that, considering that the assembled plurality of shielding plates 1 may need to be used in a vertical state, in order to further improve the stability of the plurality of shielding plates 1 during use after assembly, the embodiment can also be designed as follows:
[0053] The outer connecting part 12 is integrally formed with the shielding plate 1, and the outer connecting part 12 is in L-shaped relative to the shielding plate 1. It should be noted that the size of the outer connecting part 12 relative to the shielding plate 1 is that the outer connecting part 12 is only arranged in the middle of the end of the shielding plate 1 used for assembling other shielding plates 1, that is, the outer connecting part 12 does not need to extend to the entire end size of the shielding plate 1 used for assembling.
[0054] More specifically, one side end surface of the outer connecting part 12 is flush with the end surface of the shielding door provided with the assembly cavity 11, so that when the shielding joint assemblies of the two shielding plates 1 are matched in place, the outer connecting parts 12 connected by the two shielding plates 1 are adapted to be overlapped; and the outer connecting parts 12 on the two shielding plates 1 are adapted to be matched by the fastening screws 5. In this case, the overall width of the outer connecting part 12 on each shielding plate 1 does not need to be particularly large, and only needs to be able to satisfy the matching of the fastening screws 5.
[0055] Finally, it should be noted that the assembled electromagnetic shielding plate of the present embodiment can be combined with a shielding plate 1 of a regular shape, such as a shielding plate 1 of a rectangular parallelepiped, which can be assembled with different shielding plates 1 at four circumferential ends, and the assembly cavity 11 can be arranged on different side end surfaces of the shielding plate 1 to adapt to the shielding assembly, thereby meeting the assembly requirements, and the shielding plate 1 of the present embodiment can form a shielding module when matched with the shielding assembly, so that the shielding plate 1 can be spliced according to the requirements of different application scenarios, and is flexible and reliable to use.
[0056] Embodiment 2: Please refer to Figure 8 As shown in the assembled electromagnetic shielding plate of embodiment 1, the present embodiment provides a shielding door body made of the assembled electromagnetic shielding plate. The at least two shielding plates 1 of the assembled electromagnetic shielding plate can be assembled horizontally or vertically, and the present embodiment does not make absolute limitation. For example, when two shielding plates 1 are vertically assembled, the upper shielding plate 1 can form an upper half door piece 61 of the shielding door body, and the lower shielding plate 1 can form a lower half door piece 62 of the shielding door body.

It should be understood that the above is only a specific embodiment of the present application and is not used to limit the present application.
