As shown in fig. 8 and 12 to 14, alternatively, in the present embodiment, the linkage assembly 323 includes a guide groove 321a provided on an outer side wall of the case body 321 and a first guide portion 322b provided on an inner side wall of the case door 322, the first guide portion 322b may be embodied as a boss, a pin, a flange, or the like, which is slidably provided in the guide groove 321a, the case door 322 is turned in a direction away from the notch 314a when the first guide portion 322b slides toward one end of the guide groove 321a, and the case door 322 is turned in a direction approaching the notch 314a when the first guide portion 322b slides toward the other end of the guide groove 321 a.

Of course, the linkage assembly 323 can be other arrangements such as a link structure, so long as the box body 321 can slide to drive the box door 322 to turn over.

As shown in fig. 12 and 13, alternatively, in the present embodiment, the guide groove 321a includes a first groove section 321B and a second groove section 321c connected in sequence, a predetermined angle B is formed between the first groove section 321B and the second groove section 321c, the predetermined angle B may be a right angle or an obtuse angle, when the first guide portion 322B is located in the first groove section 321B, the box door 322 forms an angle with a horizontal plane, and when the first guide portion 322B is located in the second groove section 321c, the box door 322 is parallel with the horizontal plane. Thus, when the driving device 330 drives the box 321 to slide forward, the first guiding portion 322b slides in the first slot section 321b, and due to the limiting effect of the guiding slot 321a, the first guiding portion 322b moves forward along with the box 321, so that the box door 322 turns in a direction away from the notch 314a, and when the first guiding portion 322b slides into the second slot section 321c, the box door 322 turns to an outer surface parallel to a horizontal plane, so that the box 321 is not hindered from sliding to extend out of the notch 314a.

Considering that the box 321 may move or loosen in the vertical direction during the sliding process, as shown in fig. 8, 9, 12 and 13, optionally, in this embodiment, the outer side wall of the box 321 has a second guiding portion 321g, the inner side wall of the box frame 310 has a limiting portion 316 corresponding to the second guiding portion 321g, specifically, the second guiding portion 321g is a protruding strip, the protruding strip extends along the extending direction of the chute 314, the limiting portion 316 is specifically a limiting clip protruding, and the limiting portion 316 is disposed above the second guiding portion 321g, so as to limit the box 321 to slide along the extending direction of the chute 314, and avoid moving or loosening in the vertical direction. Of course, the box 321 and the box frame 310 may also be configured in other manners, such as a guide groove and a guide portion, to limit the sliding direction of the box 321.

In order to ensure complete opening and closing of the storage chambers and prevent the case 321 from sliding forward or backward beyond a limit, as shown in fig. 11 and 13, optionally, in this embodiment, each storage chamber is correspondingly provided with a first sensor 710, and the first sensor 710 is electrically connected to the control module 500, for detecting whether the storage chamber is in an open state or a closed state, that is, whether the drawer case 320 reaches the first state and the second state. Specifically, it is possible to detect whether the drawer box 320 reaches the first state and the second state by detecting whether the box 321 reaches the first limit position and the second limit position, where the first limit position is that the box 321 extends out of the notch 314a to a predetermined position, corresponding to the drawer box 320 reaching the first state, and the second limit position is that the box 321 is located in the notch 314a, corresponding to the drawer box 320 reaching the second state. The bottom of the box body 321 is provided with a triggering part 321i, the box frame 310 is provided with a placement groove 314c, the placement groove 314c extends along the extending direction of the sliding groove 314, the front end and the rear end of the placement groove 314c are provided with first sensors 710, the first sensors 710 are in-place sensors which can be photoelectric sensors such as optocouplers, the triggering part 321i can be a part which can be detected by the in-place sensors such as a baffle plate, the triggering part 321i reaches the first sensors 710 of the front end of the placement groove 314c when the box body 321 slides to a first limit position, the first sensors 710 detect position signals and transmit the position signals to the control module 500, the control module 500 controls the motor 331 to stop the box body 321 from sliding forwards further, and the storage cavity is in an open state at the moment; when the case 321 slides to the second limit position, the trigger portion 321i reaches the first sensor 710 at the rear end of the positioning slot 314c, and the control module 500 controls the motor 331 to stop further sliding of the case 321, and the storage chamber is in a closed state. Of course, the shielding cabinet can also adopt other in-place sensing detection modes such as an infrared sensor, so long as specific position information of the box body 321 can be detected and transmitted to the control module 500, and further the drawer box 320 is judged to be in the first state or the second state.

Considering that in an actual usage scenario, when the drawer box 320 reaches an open state, a user may not put the communication device into the box body 321 for more than a limited period of time, and when the drawer reaches a closed state, the communication device is not stored in the box body 321, so that the shielding cabinet is easy to be stored by mistake, as shown in fig. 11 to 13 and 19, optionally, in this embodiment, each storage cavity is correspondingly provided with a second sensor 720, and the second sensor 720 is electrically connected with the control module 500, so as to detect whether the communication device exists in the storage cavity. Specifically, the bottom of the box 321 has a second through slot 321h, the second through slot 321h extends along the sliding direction of the box 321, the box frame 310 is provided with a second sensor 720, the second sensor 720 is a photoelectric sensor or an infrared sensor, when the drawer box 320 is switched between the open state and the closed state, the projection of the second sensor 720 along the direction perpendicular to the bottom surface of the box 321 coincides with the projection keeping part of the second through slot 321h along the direction perpendicular to the bottom surface of the box 321, or the projection of the second sensor 720 along the direction perpendicular to the bottom surface of the box 321 is always located in the projection range of the second through slot 321h along the direction perpendicular to the bottom surface of the box 321, that is, whether the second sensor 720 can always detect whether the communication device is placed in the placement position of the box 321 through the second through slot 321h, so as to ensure the detection accuracy of the first sensor 710. Of course, the second sensor 720 may be disposed at other locations, such as a side wall or a bottom wall of the case 321, so long as detecting whether a communication device is present in the case 321 is achieved. In addition, the second sensor 720 may be another sensor such as a pressure sensor, so long as it can determine whether the communication device exists in the case 321 by receiving a certain physical quantity (such as gravity) sent by the communication device and transmitting a signal to the control module 500.

Considering that, in an actual usage scenario, when a user puts in the communication device, due to unreasonable placement position, interference between the communication device and the box door 322 or the box body 321 may occur during the process of switching the drawer box 320 from the first state to the second state, for example, when the communication device is placed at the box opening 321e, the box door 322 is blocked and cannot be turned to the notch 314a when turned towards the notch 314a, or when the box body 321 is blocked and cannot slide backward when sliding backward, as shown in fig. 19, optionally, in this embodiment, each storage cavity is correspondingly provided with a third sensor 730, and the third sensor 730 is electrically connected with the control module 500 and is used for detecting whether the drawer box 320 has a foreign object to be blocked. Specifically, the third sensor 730 may be a current-voltage sensor, which is connected to the motor 331. When the motor 331 drives the box body 321 to slide forwards or backwards and drives the box door 322 to turn over, the box door 322 or the box body 321 interferes with the communication equipment to cause the current of the motor 331 to increase and exceed a preset threshold value, the third sensor 730 detects that the current of the motor 331 exceeds the threshold value and transmits the signal to the control module 500, so that the control module is judged to have a foreign matter stuck fault, and thus, the fault detection of the drawer box 320 in switching between the first state and the second state can be realized, and the subsequent fault solution is facilitated. Of course, the third sensor 730 may be other arrangements such as an angle sensor, a position sensor, etc., for example, the turnover angle of the detecting box door 322 does not reach a predetermined angle, or the movement of the box 321 does not reach a predetermined stroke, etc., as long as the abnormal position or state of the box 321 or the box door 322 can be detected.

Because the shielding cabinet is internally provided with the driving device 330, the control module 500 and other functional equipment, the functional equipment can be other power-consumption functional components such as an anti-recording component, and the functional equipment needs to be powered by a power supply. Based on this requirement, the shielding cabinet may be powered with a charging power source or through an external power source and an internal power cord. Because the use field Jing Duowei of the shielding cabinet has the advantages of high requirements on the stability and the cruising performance of power supply in long-time or long-period secret meeting or exhibition and other scenes, the cruising performance of the built-in charging power supply is poor, the power supply stability is poor, the possibility that the shielding cabinet stops working due to low electric quantity in the meeting exists, and therefore the external power supply and the internal power supply wire are preferably adopted for power supply. However, the cabinet 100 must be provided with the wiring hole 110 to connect the internal power-consuming functional component and the external power source, so that the cabinet 100 cannot be completely sealed. Experiments have shown that electromagnetic signals may leak from the aperture both wirelessly and by way of a power line carrier.

In this embodiment, the shielding cabinet is powered by an external power source, see fig. 15, so the signal shielding module 600 is further disposed in the accommodating cavity 140.

Referring to fig. 27-32, the outer cover 612 is provided with through holes 6121 corresponding to the number of the through capacitors 632, and the inner surface of the through holes 6121 is provided with first internal threads adapted to the first external threads, so that the through capacitors 632 are assembled on the outer cover 612 in a threaded connection manner, and after assembly, the assembly is shown in fig. 32. The filter unit 630 needs to be electrically connected to the housing 610, and in the structure of this embodiment, the electrically conductive connection between the filter unit 630 and the housing 610 is achieved by assembling the external threads of the housing of the feedthrough capacitor 632 with the feedthrough hole 6121.

Referring to fig. 20 and 22, the first output terminal 6202 of the connection terminal 620 has two pins, each of which is connected to one first electric wire 6203 (conductive wire). Wherein the length L1 of the first wire via 602 is greater than 3 times its aperture (i.e., the aperture D1 of the first wire via 6111), i.e., L1>3D1.

A waveguide can be seen as a high pass filter that has an attenuation effect for all frequencies below its cut-off frequency. The length of the cut-off waveguide is at least 3 times greater than the cross-sectional diameter or the maximum linear dimension of the cross-section. The cut-off waveguide is usually of both circular and rectangular cross-section, the lowest cut-off frequency fc of the metal tube being dependent only on the inner dimensions of the cross-section of the tube. Assuming that the inner diameter of the circular waveguide is d (cm) and the length is l (cm), the lowest cut-off frequency fc and the wavelength λs of the circular waveguide are fc=17.5/d (Ghz), and λs=1.71 d. It is known that the higher the highest cut-off frequency fc of the waveguide, the larger the range of electromagnetic signals that can be shielded, as the aperture of the waveguide is smaller. In this embodiment, the wire passing hole may be regarded as a circular waveguide, d is the aperture of the wire passing hole, and according to the above formula, the aperture of the wire passing hole should be as small as possible, and the wire passing hole should be as small as possible, so that the outer surface of the wire and the inner surface of the wire passing hole are in a bonding state during passing, and the highest cut-off frequency fc of the wire passing hole is improved.

According to a calculation formula of shielding effectiveness of the circular waveguide tube on electromagnetic signals in a shielding range: s=32l/d (dB), where d is the inner diameter of the circular waveguide and l is the length of the circular waveguide. It is known that the circular waveguide tube with the length equivalent to the diameter has 32dB attenuation, when the length of the circular waveguide tube is 3 times of the diameter, the attenuation can reach 96dB, electromagnetic leakage can be restrained, and shielding efficiency on electromagnetic signals in a certain frequency band can reach more than 90dB generally, so that shielding can be realized. In this embodiment, the wire passing hole may be regarded as a circular waveguide, and d is the aperture of the wire passing hole, i.e. the wire passing hole needs to reach a certain length to completely realize signal shielding.

When the lengths of the wire passing pore canals at the two ends of the storage cavity do not meet the length required by shielding, wireless signals can directly pass through the wire passing pore canals to enter and exit the storage cavity, so that the functions of the signal shielding module are invalid. When the wire passing pore channel near one side in the cabinet does not meet the shielding required length, wireless signals in the cabinet can enter the storage cavity through the wire pore channel and are converted into wired signals on the wire at one side of the storage cavity, and then the wired signals are transmitted out of the storage cavity, so that the shielding effect is reduced. When the wire passing hole channel far away from one side in the cabinet does not meet the shielding requirement, the wire signal on the filtering unit 630 is radiated, and the generated wireless signal passes through the wire hole channel and is transmitted out of the storage cavity, so that the shielding effect is reduced.

In this embodiment, the first wire through hole 602 and the hole 6322 of the feedthrough capacitor 632 are wire through holes located at two ends of the first accommodating cavity 603. The aperture 6322 of the feedthrough capacitor 632 in the existing market must meet the shielding requirement, and the present embodiment defines that the length L1 of the first via 602 is 3 times greater than the aperture (i.e., the aperture D1 of the first via 6111), i.e., L1>3D1, so as to meet the shielding requirement, and improve the shielding effect.

Referring to fig. 23-26, the second end of the first shell portion of the circuit shell 611 is provided with a first stop portion, which is preferably a raised collar portion 6113 protruding from the outer surface of the second shell portion.

Referring to fig. 33-36, the sleeve 613 is provided with a second limit portion toward the first end of the circuit housing 611, the sleeve 613 is provided with a sleeve hole 6132 penetrating therethrough in the axial direction thereof, and the second limit portion corresponds to a concave ring portion 6131 located inside the sleeve hole 6132. When the sleeve 613 is fitted over the outer surface of the circuit housing 611, the male ring portion 6113 is caught at the female ring portion 6131, so that the second end of the circuit housing 611 cannot be separated from the first end of the sleeve 613, but the sleeve 613 is rotatable with respect to the circuit housing 611.

The outer cover 612 is assembled with the second end of the circuit housing 611 by the sleeve 613 such that there is no interlocking relationship between the outer cover 612 and the circuit housing 611, i.e., no relative rotation of the outer cover 612 and the circuit housing 611 occurs during assembly. The shell structure provided by the application enables the outer cover 612 to be assembled with the second end of the circuit shell 611 through the sleeve 613, and the sleeve 613 enables the outer cover 612 and the circuit shell 611 not to rotate relatively during assembly, so that the first electric wire 6203 between the feedthrough capacitor 632 and the connecting terminal 620 can be prevented from being wound due to rotation during assembly.

The outer cap 612 is provided with a first connection portion 6122 toward a first end of the circuit housing 611, and the first connection portion 6122 is preferably externally threaded. Referring to fig. 23-26, the second end of the sleeve 613 is provided with a second connection portion 6133, and the second connection portion 6133 is correspondingly internally threaded, so that the sleeve 613 is assembled with the outer cap 612 through threaded connection and sleeved on the outer surface of the first end of the outer cap 612. The outer surface of the second end of the outer cap 612 and the outer surface of the sleeve 613 are polygonal, so that the rotary assembly of the craftsman is facilitated.

Referring to fig. 15-16, the housing 610 is provided with mounting connections for detachably fitting at the wiring holes 110 of the shielding cage body 10, electrically connecting the housing 610 with the shielding cage body 10, and exposing the wiring terminals 620 at the wiring holes 110.

Specifically, the wiring hole 110 is provided with a fitting pipe 111 on a side facing the inside of the shield case body 10, and the inner wall surface of the fitting pipe 111 is provided with a first fitting portion, which is preferably an internal thread (not shown in the figure). Correspondingly, the outer surface of the housing 610 is provided with a second fitting portion 6112 (mounting connection portion) detachably connected with the first fitting portion, and the second fitting portion 6112 is correspondingly externally threaded, so that the housing 610 can be partially inserted into the fitting tube 111. In actual installation, the signal shielding module 600 can be conveniently installed at the wiring hole 110 by manual rotation, so that the operation is simple and the assembly and disassembly efficiency is high.

Referring to fig. 15-18, a gasket 640 is disposed between the end of the fitting tube 111 and the housing 610, the gasket 640 having a certain elastic deformability to adjust the fitting gap between the fitting tube 111 and the housing 610.

Referring to fig. 11, the outer surface of the first shell portion of the circuit shell 611 is provided with a second fitting portion 6112 (external screw thread), the outer diameters of the first shell portion and the second fitting portion 6112 are smaller than those of the second shell portion, so that a step 6114 is formed at the junction of the first shell portion and the second shell portion, and after the first shell portion is fitted with the fitting tube 111, the end portion of the fitting tube 111 abuts against the step 6114. When the gasket 640 is applied, the gasket 640 is sleeved on the first shell portion and is positioned between the end of the fitting tube 111 and the step 6114, as shown in fig. 1-2.

The assembly and installation process of the signal shielding module 600 is as follows:

in the first step, the feedthrough capacitor 632 is mounted on the outer cover 612 through a threaded connection, and then the feedthrough capacitor 632 and the filter capacitor 631 are welded to form a parallel conductive connection.

In the second step, one end of the first electric wire 6203 is welded to the first output end 6202 of the connection terminal 620, and then the connection terminal 620 is inserted into the first inner cavity 601 of the circuit shell 611 from one end of the insertion hole of the circuit shell 611, so that the first input end 6201 of the connection terminal 620 is clamped at the insertion hole, and the other end of the first electric wire 6203 passes through the first wire through hole channel 602 and out of the first wire through hole 6111.

In the third step, the other end of the first electric wire 6203 is connected to the feedthrough capacitor 632 in series by soldering.

Fourth, the sleeve 613 is sleeved from the first end of the circuit shell 611 and sleeved on the outer surface of the circuit shell 611, and the concave ring portion 6131 of the sleeve 613 is clamped with the convex ring portion 6113 of the circuit shell 611 to form a limit, so that the second end of the circuit shell 611 cannot be separated from the first end of the sleeve 613, but the sleeve 613 and the circuit shell 611 can rotate. The circuit housing 611 and the outer cover 612 are then kept from rotating relative to each other, and the rotating sleeve 613 is screwed with the outer cover 612 to complete the assembly of the housing 610.

Fifth, the gasket 640 is sleeved from the first end of the circuit shell 611 and around the outer surface of the first shell portion of the circuit shell 611. The housing 610 is then rotated to assemble the first end of the circuit housing 611 with the assembly tube 111, and the signal shielding module 600 is mounted after tightening. After the installation, only the first input end 6201 of the connection terminal 620 is exposed in the connection hole 110 and is flush with the back surface of the cabinet body 100, and does not protrude out of the surface of the cabinet body 100, so that a user can insert an external wire to supply power to the functional equipment.

The two third wires of the connection terminal 620 pass through the third wire through hole 6123A to be electrically connected with the filtering unit 630, wherein the length L3 of the third wire through hole 6123A is greater than 3 times of the aperture (i.e., the aperture D3 of the third wire through hole 6125A), i.e., L3 > 3D3.

Referring to fig. 45, the filtering unit 630 is a third-order filtering circuit board, one end of which is electrically connected to the connection terminal 620, and the other end of which is electrically connected to an internal wire (not shown) of the functional device. The filtering unit 630 is used to filter common mode and differential mode signals of the inner and outer wires.

Specifically, a first end of the filtering unit 630 (third order filtering circuit board) has a filtering input terminal, and a second end of the filtering unit 630 has a filtering output terminal. The first end of the filter unit 630 is provided with a conductive clip 631A for clamping the second end of the third wire duct 6123A, so that the third wire duct 6123A forms a conductive connection with the filter unit 630, that is, the filter unit 630 forms a conductive connection with the housing 610. The bottom of the conductive clip 631A is disposed on the filter unit 630 and forms conductive connection, and two arc plates forming a embracing structure are symmetrically disposed on the upper portion of the conductive clip 631A. The radian of the arc-shaped plates is matched with the radian of the outer surface of the third wire passing duct 6123A, a gap between the two arc-shaped plates is smaller than the outer diameter of the third wire passing duct 6123A, so that the third wire passing duct 6123A can be embedded between the arc-shaped plates from the gap, the two arc-shaped plates clamp and hold the third wire passing duct 6123A tightly, and the third wire passing duct 6123A is in stable conductive connection with the filtering unit 630 through the conductive clamping piece 631A. And, a limit part is further provided on one side of the arc plate far from the third wire passing duct 6123A, so as to prevent the third wire passing duct 6123A from passing through the arc plate to contact with other components of the filtering unit 630.

The length L2 of the fourth wire-passing hole 6132A is greater than 3 times its aperture (i.e., the aperture D2 of the fourth wire-passing hole 6133A), i.e., L2 > 3D2.

When the lengths of the wire passing pore canals at the two ends of the storage cavity do not meet the length required by shielding, wireless signals can directly pass through the wire passing pore canals to enter and exit the storage cavity, so that the functions of the signal shielding module are invalid. When the wire passing pore channel near one side in the cabinet does not meet the shielding required length, wireless signals in the cabinet can enter the storage cavity through the wire pore channel and are converted into wired signals on the wire at one side of the storage cavity, and then the wired signals are transmitted out of the storage cavity, so that the shielding effect is reduced. When the wire passing hole channel far away from one side in the cabinet does not meet the shielding requirement, the wire signal on the filtering unit 630 is radiated, and the generated wireless signal passes through the wire hole channel and is transmitted out of the storage cavity, so that the shielding effect is reduced.
