Description

Technical Field

[0001] The utility model relates to a highly flexible and anti-bending shielded wire, belonging to the technical field of shielded wires. Background Technique

[0002] A shielded wire is a transmission line that uses a metal mesh braid to wrap the signal wire. The braid is generally red copper or tinned copper. The shielding layer of the shielded wire needs to be grounded, and external interference signals can be introduced into the ground by this layer; the shielded wire is a special wire with a metal braided outer shell used to reduce the influence of external electromagnetic fields on power supply or communication lines. This shielded wire also has the function of preventing the line from radiating electromagnetic energy outward. When the shielded wire is connected and used, the shielded wire often needs to be bent, so it needs to have good flexibility.

[0003] Publication No.: CN215988138U mentions a highly flexible and anti-bending shielded wire. In this device, the position of the protective sleeve can be adjusted by adjusting the outer adjustment sleeve of the connecting wire to protect the bending part of the connecting wire. The structure is highly adjustable and very stable after protection connection. However, the length of the protective sleeve in this device is limited. When the connecting wire is bent to a large extent, it cannot fully protect the bending part of the connecting wire. At the same time, the strength is low. When subjected to a large external pressure, it will directly transmit to the connecting wire itself, making it easy to be damaged. Now there is an urgent need for a highly flexible and anti-bending shielded wire to solve the above problems. Content of the Utility Model

At the same time, the whole is light, flexible, waterproof, has good anti-tensile and wear-resistant properties, and also has a certain strength to buffer it when it is subjected to a large external pressure, ensuring that the protected part of the connecting wire is not easily damaged.

[0005] To achieve the above purpose, the utility model is realized by the following technical solutions: A highly flexible and anti-bending shielded wire includes a connecting wire main body, a cylindrical polyethylene rainproof cloth, and an elastic steel ring. PVC thickened stepped tubes are symmetrically sleeved on the left and right ends of the outside of the connecting wire main body. The cylindrical polyethylene rainproof cloth is sleeved on the outside of the connecting wire main body, and the left and right ends of the cylindrical polyethylene rainproof cloth are respectively connected to the two PVC thickened stepped tubes. Multiple creases are equidistantly arranged on the surface of the cylindrical polyethylene rainproof cloth. Multiple rubber rings are fixed at equal angles on the inner side of the cylindrical polyethylene rainproof cloth. Elastic steel rings are longitudinally arranged in multiple rubber rings. The connecting wire main body is composed of a shielded wire core, a PP mesh filling rope, an inner sheath, a water blocking layer, and an outer sheath.

[0006] Further, hand-tightening screws are inserted at both the upper and lower ends of the two PVC thickened stepped pipes by the principle of threading, and limiting pieces are installed at the threaded ends of the plurality of hand-tightening screws.

[0007] Further, the plurality of limiting pieces are respectively tightly abutted against the left and right sides of the upper and lower ends of the connecting wire body.

[0008] Further, a connector is installed at the left end of the connecting wire body.

[0009] Further, the shielded wire core is arranged in the middle of the PP mesh filling rope, the inner sheath is arranged outside the PP mesh filling rope, and the water-blocking layer is arranged outside the inner sheath.

The connecting wire body 1 is composed of a shielded wire core 10, a PP mesh filling rope 11, an inner sheath 12, a water-blocking layer 13 and an outer sheath 14. This design solves the problems in the original device that the length of the protective sleeve is limited, when the connecting wire is bent to a large extent, it cannot fully protect the bent part of the connecting wire, and at the same time, the strength is low. When subjected to a large external pressure, it will directly transmit to the connecting wire itself and is easily damaged.

Limited position pieces 4 are installed at the threaded ends of the multiple hand-tightening screws 3. The multiple limited position pieces 4 are respectively tightly abutted against the left and right sides of the upper and lower ends of the connecting wire body 1. By adding the multiple limited position pieces 4 which are respectively tightly abutted against the left and right sides of the upper and lower ends of the connecting wire body 1, the two PVC thickened stepped tubes 2 can be restricted to be fixed at the left and right ends outside the connecting wire body 1 through the hand-tightening screws 3, ensuring that when the cylindrical polyethylene rainproof cloth 5 is sleeved on the outside of the connecting wire body 1 for protection, it will not move by itself.

[0020] A connecting head 9 is installed at the left end of the connecting wire body 1. The shielded wire core 10 is arranged in the middle inside the PP mesh filling rope 11. The inner sheath 12 is arranged outside the PP mesh filling rope 11. The water-blocking layer 13 is arranged outside the inner sheath 12.

The added PP mesh filling rope 11 has excellent softness, light weight, non-hygroscopic material, strength not affected by moisture, high tensile strength, good resistance to acids and alkalis and mildew, good high-frequency insulation performance, voltage resistance, non-toxic and environmentally friendly, effectively ensuring the bending and shielding effects of the shielded wire core 10.

[0021] As the second embodiment of the present utility model: During actual use, loosen multiple hand-tightening screws 3 so that multiple limiting pieces 4 do not abut against the upper and lower ends and left and right sides of the connection line body 1. Then, pull two PVC thickened stepped tubes 2 in the opposite direction, and the cylindrical polyethylene rainproof cloth 5 can be stretched and unfolded outside the connection line body 1. Then, tighten multiple hand-tightening screws 3 again so that multiple limiting pieces 4 abut against the upper and lower ends and left and right sides of the connection line body 1 again. Furthermore, the two PVC thickened stepped tubes 2 can be restricted from moving left and right outside the connection line body 1 through the hand-tightening screws 3, ensuring that when the cylindrical polyethylene rainproof cloth 5 is sleeved outside the connection line body 1 for bending protection, it will not move by itself. Moreover, the cylindrical polyethylene rainproof cloth 5 is made of high-density polyethylene material, having strong tensile resistance and wear resistance, and also having good weather resistance, being able to maintain good performance under the influence of natural environments such as sunlight and rain, being light, soft, and having good waterproof performance, ensuring the protection performance at this part of the connection line body 1. And multiple elastic steel rings 7 provided can buffer when it is subjected to greater external pressure, ensuring that the bending protection part of the connection line body 1 is not easily damaged.
