Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding enclosure technology, and in particular to an electromagnetic shielding enclosure for preventing wire harness loosening. Background Technology

[0002] As people's awareness of the hazards of electromagnetic leakage emissions from classified information systems has deepened, various methods to prevent electromagnetic leakage emissions have begun to be widely adopted when constructing classified information networks. These methods include building electromagnetic shielding rooms, laying optical cables and shielded twisted-pair cables, using low-radiation equipment, red and black power isolation sockets, and shielded cabinets. An electromagnetic shielding enclosure (also known as an electromagnetic shielding cabinet) is a specially designed metal enclosed enclosure that protects internal electronic equipment from external electromagnetic interference (EMI / RFI) through the electromagnetic shielding effect of metal materials (reflection, absorption, and attenuation of electromagnetic waves), while preventing sensitive internal information from leaking out through electromagnetic waves.

[0003] Electromagnetic shielding enclosures typically contain numerous connecting wires. These wires are often placed randomly based on their position, resulting in a messy and disorganized interior. This makes it difficult to quickly locate the desired wires. Furthermore, the lack of restraint and fixation for these wires means that loose wires may come into contact with other conductive components due to vibration or movement, potentially causing electrical short circuits, fires, or equipment damage. Therefore, this paper proposes an electromagnetic shielding enclosure to prevent wire loosening. Utility Model Content

[0015] 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.

[0016] Example: Refer to Figure 1-7 An electromagnetic shielding enclosure for preventing wire harness loosening includes an electromagnetic shielding enclosure body 1, a door 2 on one side of the enclosure body 1, a fixed frame 3 fixedly installed on the inner wall of the enclosure body 1, a wedge-shaped hole 4 on one side of the fixed frame 3, a side fixing plate 5 fixedly installed on the inner wall of one side of the wedge-shaped hole 4, and a wedge-shaped adjusting plate 6 installed on the inner wall of one side of the wedge-shaped hole 4 via a sliding guide assembly. An adjustment and positioning assembly is provided between the wedge-shaped adjusting plate 6 and the fixed frame 3. The sliding guide assembly includes a strip guide rod 7 fixedly installed on the inner wall of the wedge-shaped hole 4, and one side of the wedge-shaped adjusting plate 6... A strip-shaped guide hole 8 is provided on the side, and a strip-shaped guide rod 7 is located inside the strip-shaped guide hole 8. Rubber pads 18 are fixedly installed on one side of the wedge-shaped adjusting plate 6 and the side fixing plate 5. The wire harness to be fixed is passed through the wedge-shaped hole 4, and then the pulling belt 9 is pulled to one side. The movement of the pulling belt 9 causes the wedge-shaped adjusting plate 6 to move within the wedge-shaped hole 4. The strip-shaped guide rod 7 and the adjusting guide hole 8 can limit the position of the movement of the wedge-shaped adjusting plate 6. The wedge-shaped adjusting plate 6 moves closer to the side fixing plate 5, thereby pressing and fixing the wire harness that has passed through. The rubber pads 18 can better squeeze and extrude, and have a good anti-slip effect.

[0017] Specifically, the adjusting positioning assembly includes a mounting frame 10 fixedly installed on the top of the fixed frame 3. A through hole is provided on one side of the mounting frame 10. A pull belt 9 is rotatably installed on one side of the wedge-shaped adjusting plate 6, with one end of the pull belt 9 passing through the through hole. A fixing block 11 is fixedly installed on one side of the mounting frame 10. A rotating screw 12 is threaded onto the fixing block 11. A connecting block 13 is rotatably installed at the bottom end of the rotating screw 12. A blocking plate 16 is rotatably installed at the bottom of the connecting block 13. Multiple triangular blocking blocks 17 are fixedly installed on the top of the pull belt 9, with the blocking plate 16 blocking one side of a triangular blocking block 17. A limit groove 14 is provided on one side of the mounting frame 10. A limit block 15 is fixedly installed on one side of the connecting block 13, and the limit block 15 slides within the limit groove 14. The movement of the pull belt 9 causes the triangular blocking blocks 17 to move. The inclined surface of the blocking block 17 contacts the blocking plate 16. The blocking plate 16 can rotate to one side without affecting the movement of the pulling belt 9. When pulled to the position, the triangular blocking block 17 and the blocking plate 16 are misaligned, and the blocking plate 16 falls vertically and blocks the vertical surface of the triangular blocking block 17, thereby achieving the function of blocking and fixing. The position of the wedge-shaped adjusting plate 6 after movement is fixed, thereby achieving the constraint and fixation of the wire harness and playing a good role in preventing loosening. When the wire harness is readjusted, the wedge-shaped adjusting plate 6 needs to be loosened by the rotating screw 12. After the rotating screw 12 rotates, it drives the connecting block 13 to move upward, thereby driving the blocking plate 16 to move upward. At this time, the pulling belt 9 can move freely, and the wedge-shaped adjusting plate 6 can achieve position adjustment. The limiting block 15 and the limiting groove 14 can limit the position of the connecting block 13.

[0018] Specifically, two constraint frames 19 are fixedly installed on the inner wall of the electromagnetic shielding enclosure 1. The two constraint frames 19 are located on both sides of the fixed frame 3. An inlet / outlet hole 21 is provided on one side of the constraint frame 19. A wire harness clamping assembly is provided inside the constraint frame 19. The wire harness clamping assembly includes a clamping plate 20 movably installed inside the constraint frame 19. Multiple compression springs 22 are fixedly installed between the side of the clamping plate 20 and the inner wall of the constraint frame 19. A moving groove 23 is provided on one side of the constraint frame 19. A moving block 24 is fixedly installed on one side of the clamping plate 20 and movably installed in the moving groove 23. Constraint frames 19 are provided on both sides of the fixed frame 3. Both ends of the wire harness passing through the fixed frame 3 are located inside the constraint frames 19, which can constrain the cable from both ends. The inlet / outlet hole 21 is provided. The compression plate 20 is positioned below the inlet / outlet hole 21. This facilitates the placement and removal of the wire harness. After the wire harness is placed, the clamping plate 20 can clamp the wire harness to a certain extent under the pushing action of the compression spring 22.

[0019] In use: The electromagnetic shielding box body 1 is welded from cold-rolled steel plate to form a fully enclosed box. It uses the electromagnetic shielding effect (reflection, absorption, and attenuation of electromagnetic waves) to protect the internal electronic equipment from external electromagnetic interference. The wire harness that needs to be fixed is passed through the wedge hole 4. Pulling the pull belt 9 moves the wedge adjustment plate 6. With the help of the side fixing plate 5, the wire harness can be pressed and fixed. The rubber pad 18 can better squeeze and squeeze out, and has a good anti-slip effect. When pulled to the position, the blocking plate 16 blocks the vertical surface of the triangular blocking block 17, thereby achieving the blocking and fixing effect, thus achieving the constraint and fixing of the wire harness and playing a good role in preventing loosening. The fixing frame 3 is equipped with constraint frames 19 on both sides, which can constrain the cable from both ends. After the wire harness is placed, under the pushing action of the compression spring 22, the pressing plate 20 can press the wire harness to a certain extent, which is convenient to use.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
