[0031] Please refer to Figure 1 And Figure 4 The embodiment provides an electromagnetic shielding box 100, comprising a box body 110 with an opening on the front side, and a box door 120 is hinged on the opening of the box body 110; a wiring board 130 is arranged on the rear side of the box body 110, an interface panel 140 is arranged on the wiring board 130, and an interface 141 is arranged on the interface panel 140, and the interface 141 is used for being connected with a communication module to be tested; further comprising a receiving assembly 150, the receiving assembly 150 is arranged on the bottom surface of the box body 110 and located between the interface panel 140 and the box door 120, the receiving assembly 150 comprises a supporting table plate 151 and at least two supporting parts 152, and the supporting table plate 151 is used for placing the communication module to be tested; the at least two supporting parts 152 are arranged on one side of the supporting table plate 151 towards the bottom surface of the box body 110, and the supporting part 152 is telescopic to adjust the interval distance between the supporting table plate 151 and the bottom surface of the box body 110.

[0032] Specifically, as shown in Figure 4 The electromagnetic shielding box 100 comprises a box body 110 and a box door 120, and the box body 110 and the box door 120 form an internally closed accommodating cavity; the box body 110 is internally provided with a wiring board 130, and an interface panel 140 is arranged on the wiring board 130; in order to facilitate the connection between the to-be-tested communication module and the interface 141 on the interface panel 140, the plane on which the wiring board 130 and the wiring panel are located is parallel to the box door 120.

[0033] As shown in Figure 1 The accommodating cavity of the box body 110 is further provided with a bearing assembly, and the bearing assembly comprises a support platform 151, which is used for placing the to-be-tested communication module, so as to realize the connection between the to-be-tested communication module and the interface 141 through the support of the support platform 151; however, the relative height difference between the interface 141 and the to-be-tested communication module is not fixed, and if the relative height difference between the interface 141 and the to-be-tested communication module is large, the to-be-tested communication module is prone to loosening or falling off from the interface 141 after being connected with the interface 141 due to its own gravity. Therefore, in order to adapt to the height difference between the interface 141 and the to-be-tested communication module and realize the stable connection between the to-be-tested communication module and the interface 141, the interval distance of the support platform 151 of the bearing assembly relative to the bottom surface of the box body 110 can be adjusted through the extension of the support part 152.

[0034] When the relative height difference between the to-be-tested communication module and the interface 141 is large, the support part 152 is only needed to be driven to be elongated, so as to reduce the relative height difference between the to-be-tested communication module and the interface 141, and ensure that the to-be-tested communication module is always supported by the support platform 151, thereby avoiding the situation that the to-be-tested communication module is loosened or falls off from the interface 141 after being connected with the interface 141 due to the influence of its weight.

[0035] It should be noted that in an implementation manner of the present application, first, in order to facilitate the opening and closing of the box door 120, a handle 121 is arranged on the outer side surface of the box door 120.

[0036] Second, in order to improve the working reliability of the electromagnetic shielding box 100 and prolong the service life of the electromagnetic shielding box 100, prevent the damage of the parts of the electromagnetic shielding box 100 due to the influence of high temperature caused by long-term work, a heat dissipation plate and a heat dissipation motor are further arranged on the side plate of the box body 110, and the heat dissipation plate can dissipate heat and cool the circuit board and other parts in the box body 110.

[0037] Third, in order to ensure that the support platform 151 has sufficient area to carry the communication module to be tested, while effectively and reasonably utilizing the space in the box 110, the length of the support platform 151 along the first direction a is less than the length of the box 110 along the first direction a, and the first direction a is the direction of the connection line of the wiring board 130 and the box door 120, which can provide space for the arrangement of the wiring board 130 and the interface panel 140; the length of the support platform 151 along the second direction b is equal to the length of the box 110 along the second direction b, and the second direction b is perpendicular to the first direction a, so as to increase the area of the support platform 151 and ensure that it can carry the communication module to be tested.

[0038] Fourth, since the metal material has good conductivity and magnetic properties, it can effectively shield electromagnetic waves and prevent electromagnetic interference, so the box 110 and the box door 120 are both made of metal material. The electromagnetic shielding box 100 composed of the metal material box 110 and the metal material box door 120 can reflect and absorb electromagnetic waves, prevent external electromagnetic waves from entering the inside of the shielding box, and also prevent the electromagnetic waves inside the shielding box from leaking out, thereby avoiding the interference of electromagnetic waves on other devices or systems and improving the test reliability of the electromagnetic shielding box 100.

[0043] It should be noted that the extension and contraction of the support part 152 can be realized by other ways in addition to the above-mentioned hinged cooperation of the first support rod 1521, the second support rod 1522 and the damping shaft 1523, for example, in another embodiment of the present application, the first support rod 1521 and the second support rod 1522 are both provided with through holes, the first support rod 1521 can slide along the second support rod 1522 to make the through hole on the first support rod 1521 coaxially arranged with the through hole on the second support rod 1522; the through holes are used for penetrating the fixing member; the spacing distance of the support platform 151 relative to the bottom surface of the box body 110 is adjusted according to the relative height difference between the to-be-tested communication assembly and the interface 141, the first support rod 1521 is slid along the second support rod 1522 to the extension of the support part 152 to the appropriate height, at this time, the through hole of the first support rod 1521 and the through hole of the second support rod 1522 are sequentially penetrated by the fixing member to fix the relative position of the first support rod 1521 and the second support rod 1522; the specific extension and contraction mode of the support part 152 is not limited in the present application, as long as the support part 152 can adjust the height of the support platform 151 relative to the bottom surface of the box body 110 to enable the to-be-tested communication module to be placed on the support platform 151 while being connected with the interface 141 of the interface panel 140.

[0044] Optionally, the side of the support platform 151 facing the support part 152 is provided with a first mounting groove, and the end of the first support rod 1521 away from the second support rod 1522 is hingedly arranged in the first mounting groove through the damping shaft 1523; the bottom surface of the box body 110 is provided with a second mounting groove, and the end of the second support rod 1522 away from the first support rod 1521 is hingedly arranged in the second mounting groove through the damping shaft 1523.

[0045] Specifically, in order to further improve the connection stability of the receiving assembly 150, one end of the first support rod 1521 away from the second support rod 1522 is hinged to the support platform 151 through a damping shaft 1523, and one end of the second support rod 1522 away from the first support rod 1521 is hinged to the bottom surface of the box body 110 through a damping shaft 1523. In order to facilitate the installation of the damping shaft 1523, a first installation slot is formed on one side of the support platform 151 facing the support part 152, and a second installation slot is formed on the bottom surface of the box body 110.
