Description

Technical Field

[0001] The utility model relates to a braided shielded wire with waterproof effect, belonging to the technical field of braided 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 tin-plated 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 kind of shielded wire also has the function of preventing the line from radiating electromagnetic energy outward.

[0003] However, during the use of the existing shielded wires, the protective structure at the joint is single and vulnerable to environmental influences, making it easy for water vapor to erode the joint connection, resulting in a short circuit in the line. Now there is an urgent need for a braided shielded wire with waterproof effect to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a braided shielded wire with waterproof effect to solve the problems raised in the above background technique. The utility model designs a multi-layer protection and stretching waterproof structure, which can wrap and waterproof the joint of the shielded wire.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A braided shielded wire with waterproof effect includes a PVC outer sheath, a joint shell, a double-layer threaded shell, and a polyethylene waterproof cloth. A braided shielding net is arranged inside the PVC outer sheath, an aluminum foil shielding layer is arranged inside the braided shielding net, and a filling layer is filled inside the aluminum foil shielding layer. A plurality of inner core insulating layers are arranged inside the filling layer, and tin-plated copper wire cores are arranged inside each of the plurality of inner core insulating layers. The joint shell is installed at the lower end of the PVC outer sheath. The double-layer threaded shell is screwed outside the joint shell by the thread principle. A first flame-retardant rubber ring is fixed at the lower end of the double-layer threaded shell. A hollow outer ring is fixed outside the first flame-retardant rubber ring. A polyethylene waterproof cloth is folded at the gap between the hollow outer ring and the first flame-retardant rubber ring. A elastic rubber ring is sleeved outside the lower end of the first flame-retardant rubber ring. A second flame-retardant rubber ring is integrally arranged at the lower end of the first flame-retardant rubber ring.

[0006] Furthermore, the lower ends of the plurality of tin-plated copper wire cores are all installed inside the joint shell.

[0007] Furthermore, anti-slip patterns are fixed at the upper end of the double-layer threaded shell.

[0008] Furthermore, the elastic rubber ring is connected to the lower end of the polyethylene waterproof cloth.

[0009] Furthermore, a plurality of arc-shaped grooves are equiangularly formed at the lower end of the annular side surface of the second flame-retardant rubber ring.

[0010] Furthermore, the other end of the polyethylene waterproof cloth is fixed to the upper end inside the hollow outer ring.

[0011] Advantages of the present utility model: A braided shielded wire with a waterproof effect according to the present utility model. Due to the addition of a double-layer threaded shell, anti-slip patterns, a first flame-retardant rubber ring, a second flame-retardant rubber ring, a hollow outer ring, a polyethylene waterproof cloth, and an elastic rubber ring in the present utility model, through our design improvement and actual use, it shows that the device has a reasonable structure, good practicability, and a multi-layer protection and tensile waterproof structure is designed, which can wrap and waterproof the shielded wire joint, thereby achieving a good waterproof effect and having simple operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a braided shielded wire with waterproof effect, including a PVC outer sheath 6, a connector housing 7, a double-layer threaded housing 8 and a polyethylene waterproof cloth 14. A braided shield net 5 is arranged inside the PVC outer sheath 6, an aluminum foil shielding layer 4 is arranged inside the braided shield net 5, and a filling layer 3 is filled inside the aluminum foil shielding layer 4. A multi-strand inner core insulating layer 2 is arranged inside the filling layer 3, and a tinned copper wire core 1 is arranged inside each multi-strand inner core insulating layer 2. The connector housing 7 is installed at the lower end of the PVC outer sheath 6. The double-layer threaded housing 8 is screwed on the outside of the connector housing 7 by the thread principle. A first flame-retardant rubber ring 10 is fixed at the lower end of the outside of the double-layer threaded housing 8. A hollow outer ring 13 is fixed on the outside of the first flame-retardant rubber ring 10. A polyethylene waterproof cloth 14 is folded at the gap between the hollow outer ring 13 and the first flame-retardant rubber ring 10. A elastic rubber ring 15 is sleeved on the lower end of the outside of the first flame-retardant rubber ring 10. A second flame-retardant rubber ring 11 is integrally arranged at the lower end of the first flame-retardant rubber ring 10. This design solves the problem that in the process of using the original shielded wire, the protection structure at the joint is single and vulnerable to environmental influence, making water vapor easily erode the joint connection, resulting in a short circuit phenomenon in the line.

[0019] As the first embodiment of the present utility model: The lower ends of the multi-strand tinned copper wire cores 1 are all installed in the connector housing 7. An anti-slip pattern 9 is fixed at the upper end of the outside of the double-layer threaded housing 8. By adding the anti-slip pattern 9, it is convenient for the staff to rotate the double-layer threaded housing 8.

[0020] The elastic rubber ring 15 is connected to the lower end of the polyethylene waterproof cloth 14, and the added elastic rubber ring 15 can be removed from the lower end of the outside of the first flame-retardant rubber ring 10. A plurality of arc-shaped grooves 12 are equally angled and opened at the lower end of the circumferential side of the second flame-retardant rubber ring 11. By adding the plurality of arc-shaped grooves 12, it is convenient for the lower end of the second flame-retardant rubber ring 11 to open. The other end of the polyethylene waterproof cloth 14 is fixed to the upper end inside the hollow outer ring 13. The added polyethylene waterproof cloth 14 is a common rainproof cloth material. It has the characteristics of being light, soft and good waterproof performance. It is made of high-density polyethylene material and has strong tensile resistance, wear resistance and weather resistance, and can maintain good performance under the influence of natural environments such as sunlight and rain.

[0021] As the second embodiment of the present utility model: When other connectors are inserted into the connector housing 7 (Note: The braided shielded wire composed of the tinned copper wire core 1, the inner core insulation layer 2, the filling layer 3, the aluminum foil shielding layer 4, the braided shielding net 5 and the PVC outer sheath 6 is a mature existing product, and its structural functions will not be elaborated here), pinch the anti-slip pattern 9 and rotate it downward, then the double-layer threaded housing 8, the first flame-retardant rubber ring 10, the second flame-retardant rubber ring 11 and the hollow outer ring 13 will rotate downward accordingly. Until the second flame-retardant rubber ring 11 completely covers the outside of other connectors, remove the elastic rubber ring 15 from the lower end outside the first flame-retardant rubber ring 10 and sleeved it on the lower end outside the second flame-retardant rubber ring 11. During this process, the stacked polyethylene waterproof cloth 14 can be pulled out from the inside of the hollow outer ring 13 and completely cover the second flame-retardant rubber ring 11, and the contraction of the elastic rubber ring 15 will drive the lower opening of the second flame-retardant rubber ring 11 to contract (refer to Figure 3 ), and the lower ends of the multiple arc-shaped grooves 12 also contract, so that the second flame-retardant rubber ring 11 will tightly wrap other connectors, thereby ensuring the sealing and waterproofness of the connection between other connectors and the connector housing 7.
