[0002] In the field of electronic equipment research and development and testing, electromagnetic interference shielding is a key link to ensure signal purity and accurate test results. With the rapid development of wireless communication, radio frequency technology and precision electronic instruments, the demand for electromagnetic shielding equipment is becoming increasingly urgent. Manually operated side-opening shielding boxes are special equipment developed to meet this demand.

[0003] There are many types of existing manual side-opening shielding boxes. The space inside the shielding box is small, the insertion and connection actions are inconvenient, which affects the difficulty of workers' operation, consumes more time, and has low testing efficiency. In order to solve the above problems, the shielding box disclosed in the prior art (Chinese patent application number CN202110493943.2, application date 2021-05-07) can be referred to. This shielding box facilitates the staff to conduct tests, improves the testing efficiency, reduces the difficulty of putting the workpiece to be tested into the shielding box, shortens the placement time, and improves the testing efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-7 The present invention provides the following technical solution: a manually operated side-opening shielded box with modular interface assembly.

[0019] Example 1: For ease of use of the shielding box, please refer to the attached document. Figure 1 - Appendix Figure 4 The enclosure includes a housing 1. Two cooling fans 4 are installed on one side of the interior of housing 1. A modular receiver module unit 5 is located on the back of housing 1. A fiber optic transceiver 6 is fixed to the inside of housing 1, away from the cooling fans 4. A power strip 7 is fixed to the upper part of the fiber optic transceiver 6. A door panel 2 is hinged to the front and rear of housing 1, and a handle 3 for manual opening and closing is installed on the door panel 2. The handle 3 is latched to one side of housing 1. The interior of housing 1 is lined with Blue Peak insulation. Cotton 101; The receiver module unit 5 includes a USB interface 51 inside. A connection interface 53 is installed on one side of the USB interface 51. An AC / DC interface 54 is provided at the lower end of the USB interface 51 and the connection interface 53. A waveguide 52 is provided at the lower end of the AC / DC interface 54. Several sets of RF coaxial connectors 55 and SMA-SMA connectors 56 are provided below the waveguide 52. The receiver module unit 5 is installed on the outside of the rear door panel 2. A sealing strip is attached to the edge of the door panel 2. The outside of the sealing strip is tightly attached to the frame of the enclosure 1.

[0020] The front and rear sides of the enclosure 1 are connected to the door panel 2 via hinges. Operators can manually open and close the door panel 2 using the handle 3 on it. To open the door, the handle 3 is unlocked from the lock on the enclosure 1, and the door panel 2 is rotated outwards to insert or remove the test object. After closing the door, the handle 3 is re-locked to ensure the door panel 2 is tightly closed, solving the problem of inconvenient access in traditional shielding boxes. The interior of the enclosure 1 is lined with blue-peaked cotton 101, which absorbs stray electromagnetic waves within the enclosure. Simultaneously, the sealing strips on the edges of the door panel 2 fit tightly against the frame of the enclosure 1, blocking external electromagnetic interference from entering or internal signal leakage. This dual structure ensures the protection of the test object. The signal purity during testing ensures accurate test results. The receiver module unit 5 is modularly installed on the outside of the rear door panel 2. Its integrated USB interface 51, connection interface 53, AC / DC interface 54, waveguide 52, RF coaxial connector 55, and SMA-SMA connector 56 can be connected to different test equipment as needed to adapt to diverse test requirements. The cooling fan 4 inside the enclosure 1 accelerates air circulation and prevents the equipment from overheating. The fiber optic transceiver 6 ensures signal transmission, and the power strip 7 provides a power interface, together supporting the stable operation of the test equipment.

[0021] Example 2: To address the issue that in current shielded boxes on the market, after the test object is placed inside, it is necessary to electrically connect the interface to the object being tested. However, the wires are often tangled and disorganized, making wire management cumbersome. Please refer to the attached... Figure 1 - Appendix Figure 3 and attached Figure 5 - Appendix Figure 7 Inside the housing 1, near the receiving module unit 5, a wire harnessing mechanism is provided. This mechanism includes two sets of opposing wire harness blocks 8. A rotating rod 11 is fixed to the bottom of the lower wire harness block 8, and the bottom of the rotating rod 11 is rotatably positioned inside the housing 1. A threaded rotating rod 13 is rotatably positioned on the outside of the lower wire harness block 8, and the outer side of the threaded rotating rod 13 is threadedly connected to the inner side of the upper wire harness block 8. The wire harnessing mechanism acts on the outside of the wires inside the housing 1, constraining the wires. Inside the housing 1, an insert block 9 is also slidably positioned. The outer side of the insert block 9 is connected to the inside of the housing 1 via a return spring 10, and the outer end of the insert block 9 extends into… Inside the insertion hole 12 at the bottom of the rotating rod 11, a guide mechanism is provided between the two sets of wire harness blocks 8. The guide mechanism includes a piston rod 14 fixed at the inner corner of one set of wire harness blocks 8, and the outer side of the piston rod 14 is slidably disposed inside the receiving cylinder 15 fixed to the other set of wire harness blocks 8. A bidirectional pressure nozzle 141 is also installed on the outer side of the piston rod 14. The outer side of the piston rod 14 is connected to the fitting airbag 16, which is adhered to the arc-shaped inner side of the wire harness block 8. The fitting airbag 16 is made of elastic rubber, and the contact position between the fitting airbag 16 and the wire is fitted with a wear-resistant and anti-slip sheet. The elasticity of the fitting airbag 16 is greater than that of the bidirectional pressure nozzle 141.

[0022] The two sets of wire harness blocks 8 of the wire harness mechanism are arranged opposite each other. The operator can rotate the threaded rotating rod 13 on the outer side of the lower wire harness block 8. Because the threaded rotating rod 13 is threadedly connected to the upper wire harness block 8, the rotation will drive the upper wire harness block 8 to move up and down, thereby adjusting the distance between the two sets of wire harness blocks 8 to accommodate wires of different thicknesses. The lower wire harness block 8 is rotatably connected to the housing 1 through the rotating rod 11. The angle of the wire harness block 8 can be adjusted by rotating the rotating rod 11 according to the wire routing. After adjustment, the embedded block 9 in the housing 1 automatically extends into the insertion hole 12 at the bottom of the rotating rod 11 under the elastic force of the return spring 10, locking the position of the rotating rod 11 and preventing... The guide mechanism between the two sets of cable bundles 8 can limit the movement direction of the cable bundles 8, ensuring smooth movement of the cable bundles 8 when adjusting the spacing and avoiding misalignment. At the same time, the bidirectional pressure nozzle 141 on the outside of the piston rod 14 can adjust the airflow, causing the fitting airbag 16 connected to the piston rod 14 to expand. The fitting airbag 16 adheres to the arc-shaped inner side of the cable bundle 8, and after expansion, it tightly fits the surface of the wire. Its wear-resistant and anti-slip plate can prevent the wire from sliding. Because the elasticity of the fitting airbag 16 is greater than that of the bidirectional pressure nozzle 141, it can adapt to the shape of the wire to achieve flexible clamping, and finally complete the wire straightening, completely solving the problem of tedious wire management.
