Description

Technical Field

[0001] This invention relates to an improvement in shielded wire grounding technology, belonging to the field of electrical connection devices, and particularly to a shielded wire grounding system. Background Technology

[0002] With the trend of digitalization and miniaturization of electronic and communication equipment, shielded grounding systems have emerged to prevent interference from electromagnetic waves generated by electromagnetic wave sources and to address the issue of the harmfulness of electromagnetic waves to humans. The main function of shielded grounding systems is to reduce or eliminate electromagnetic interference, protect signal lines from the influence of external electromagnetic fields, and prevent electromagnetic interference from signal lines to the external environment. The shielding layer is usually made of conductive materials, such as copper or aluminum, and it surrounds the signal line. By grounding, it can effectively guide the interference current into the earth, thereby achieving the shielding effect. However, vibration or impact of equipment may cause the connection of the shielding wire to loosen, thus affecting the shielding effect. In existing shielded grounding systems, the connection stability and sealing effect of the shielding wire are poor, and it cannot provide good protection for the connection between the shielding wire and the terminal.

[0003] Chinese patent application CN201922233835.2, filed on December 12, 2019, discloses a shielded wire grounding device. The device includes a shielded wire and a grounding component, with the grounding component electrically connected to the shielding layer of the shielded wire. Along the length of the shielded wire, a grounding portion is located in the middle section, with the shielding layer of the grounding portion exposed outside the shielded wire. The shielding layer of the grounding portion is electrically connected to the grounding component. This allows the current in the shielding layer at each point along the length of the shielded wire to be quickly discharged through the grounding component connected to the grounding portion. This improves the shielding capability of the shielded wire grounding device against the electromagnetic field of the shielded wire, reduces electromagnetic interference from the shielded wire's electromagnetic field to surrounding equipment, and facilitates the normal operation of surrounding equipment. However, this technology does not solve the problem of poor connection stability of the shielded wire.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In a shielded grounding system of the present invention, a second cavity is provided inside the connecting block. The inner wall of the second cavity is connected to one end of two first springs, and the other end of the two first springs is connected to one side of a rectangular block. One side of the rectangular block is located between the two first springs and connected to one end of a rack. The other end of the rack is connected to one end of a first conical block. A second conical block is provided at the bottom of the first conical block, and a stop block is provided at the bottom of the second conical block. Second springs are provided on both sides of the fixing plate. The two sides of the second springs are respectively connected to the inner walls of the second conical block and the connecting block. In application, the connecting block drives the shielded wire assembly to move towards the electrical equipment body. At this time, the conductive slider will first contact the electrical equipment body. The plug is inserted into the socket for charging, ensuring the device is electrically shielded before connection. This guarantees the shielding and grounding performance of the device during use. Simultaneously, the rectangular block, rack, and first conical block move under the action of the electrical equipment body, causing the second conical block to drive the fixing plate to insert into one side of the stop block. The stop block and fixing plate quickly and stably fix the connecting block to the electrical equipment body, ensuring the connection stability between the electrical equipment body and the shielding wire assembly. Furthermore, the rectangular sealing gasket and connecting block protect the connection between the electrical equipment body and the shielding wire assembly from external impurities and moisture, preventing long-term impact on its service life and signal transmission stability. Therefore, the shielding wire of this invention exhibits good connection stability.

[0017] 2. In the shielded grounding system of this invention, a limiting component is used to house a gear within a second cavity. The gear meshes with a rack, and a first rotating shaft is located within the gear and housed within a connecting block. A ratchet is fixedly connected to the outer perimeter of the first rotating shaft, and a pawl is located on one side of the ratchet. A connecting shaft is installed within the pawl, and the end of the connecting shaft away from the pawl is rotatably connected to a second threaded sleeve. During application, the rack moves, causing the gear, the first rotating shaft, and the ratchet to rotate counterclockwise. The pawl prevents the ratchet from rotating clockwise, thus autonomously limiting the position of the gear and rack, further improving the stability of the device during connection and preventing external vibrations from affecting the connection stability. Operating the second handle causes the second bevel gear, the first bevel gear, and the lead screw to rotate, causing the second threaded sleeve to move the pawl and the connecting shaft, releasing the restriction effect of the pawl on the ratchet. At this point, driving the connecting block disconnects the electrical equipment body and the shielded wire assembly, effectively improving the portability of the device. Therefore, this invention provides a stable connection and is simple to operate.

[0018] 3. In the shielded wire grounding system of the present invention, a first cavity is provided inside the connecting block. A positive and negative lead screw is rotatably connected inside the first cavity. The top end of the positive and negative lead screw extends to the outside of the connecting block and connects to a first rotating handle. A first threaded sleeve is threaded onto the positive and negative lead screw. The outer side of the first threaded sleeve is connected to two sliding plates, and the opposite side of the two sliding plates is connected to a shaped fixing block. In application, driving the first rotating handle causes the positive and negative lead screw to rotate, causing the two first threaded sleeves to move relative to the two sliding plates and the shaped fixing block. The shaped fixing block contacts the outer surface of the outer insulation layer to ensure the stability of the connection between the connecting block and the shielded wire assembly. Therefore, the present invention is easy to adjust and safe to use. Attached Figure Description

[0040] In application: The drive connecting block 4 inserts one side of the first cavity 51 into the stripped shielded wire assembly 3.

A conductive slider 10 is slidably connected to the outer periphery of the shielding wire 34, and the conductive slider 10 is installed inside the third cavity 8.

[0042] In application, the drive connecting block 4 inserts one side of the first cavity 51 into the stripped shielded wire assembly 3. At this time, the outer insulation layer 35 is located on one side of the connecting block 4. The drive connecting block 4 moves the shielded wire assembly 3 towards the electrical device body 1.

This ensures that the device is shielded before electrical connection, thus guaranteeing the shielding and grounding performance of the device during use. At the same time, the stop block 69 will enter the second cavity 61. The rectangular block 63 and the rectangular sealing gasket will first contact the electrical device body 1, and under the action of the electrical device body 1, the rectangular block 63 will move towards the electrical device body 1. The shaped block 63 drives the rack 64 and the first conical block 65 to move towards the second conical block 66, and the second conical block 66 compresses the second spring 68, causing the second conical block 66 to drive the fixing plate 67 to be inserted into one side of the stop block 69. The stop block 69 and the fixing plate 67 quickly and stably fix the connecting block 4 to the electrical equipment body 1, ensuring the connection stability between the electrical equipment body 1 and the shielded wire assembly 3. At the same time, the rectangular sealing gasket and the connecting block 4 protect the connection between the electrical equipment body 1 and the shielded wire assembly 3 to prevent external impurities and moisture from entering the connection, thereby preventing long-term impact on its service life and signal transmission stability.

[0044] In application: During movement, rack 64 drives gear 71, first shaft 72, and ratchet 73 to rotate counterclockwise, while pawl 74 prevents ratchet 73 from rotating clockwise. This allows for autonomous limitation of the positions of gear 71 and rack 64, further improving the stability of the device during connection and preventing external vibrations from affecting the connection stability. When disassembly is required, the second handle 713 is driven, causing it to rotate the second bevel gear 711. The second bevel gear 711 and the first bevel gear 710... The linkage effect between them transmits power to the first bevel gear 710, causing the first bevel gear 710 to drive the lead screw 79 to rotate. Then, the linkage effect between the lead screw 79 and the second threaded sleeve 76 is used to transmit power to the second threaded sleeve 76, causing the second threaded sleeve 76 to drive the pawl 74, connecting shaft 75, plate 77 and third spring 78 to move, releasing the restriction effect of the pawl 74 on the ratchet 73. At this time, the drive connecting block 4 can disconnect the electrical equipment body 1 and the shielding wire assembly 3, effectively improving the portability of the device.
