Description

Technical Field

[0001] This utility model relates to the field of sensor cable technology, specifically to a flexible bending protection structure for sensor cables. Background Technology

[0002] A sensor cable is a cable used to connect sensors and control systems. It primarily transmits the signal data collected by the sensors, thereby enabling the monitoring and control of various physical quantities. The following is a detailed introduction to sensor cables: The basic principle of sensor cables is to utilize physical effects to convert the measured physical quantity into an electrical signal that has a certain functional relationship with it. This signal is then transmitted through the cable to a display, recording, or control device to achieve the monitoring or control of the physical quantity. As a crucial component connecting sensors and control systems, the electrical performance of sensor cables is essential to the stability and reliability of industrial automation systems. Good electrical performance ensures accurate signal transmission.

[0003] Common sensor cables typically consist of conductive cores, insulation, shielding, and a sheath. The conductive cores are the conductors that transmit signals and are usually made of high-purity copper or tin-plated copper. These materials have excellent conductivity, ensuring accurate signal transmission. The insulation layer, which wraps around the conductive cores, should have good electrical insulation and temperature resistance to prevent current leakage and short circuits. The shielding layer resists external electromagnetic interference, protecting the integrity of signal transmission, and is usually made of braided metal mesh or metal tape for effective shielding. The sheath is the outermost layer of the sensor cable, protecting it from mechanical damage and environmental corrosion.

[0004] Traditional sensor cables, when subjected to frequent bending or movement, are prone to internal conductor breakage or outer sheath damage due to prolonged bending stress, affecting normal sensor operation and data transmission. To address this issue, a flexible bending protection structure for sensor cables is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a flexible bending protection structure for sensor cables, thereby solving the technical problem of wire breakage or outer sheath damage affecting the normal operation of sensors and data transmission.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flexible bending protection structure for sensor cables, comprising a conductive core, an insulating outer sheath connected to the surface of the conductive core, a protective sleeve fitted over the surface of the insulating outer sheath, reinforcing ribs evenly distributed within the inner cavity of the protective sleeve, and positioning grooves evenly distributed on the surface of the protective sleeve. A bending guide shaft is added to the outer side of the protective sleeve, and a connecting seat is rotatably connected to the end of each bending guide shaft. A guide sleeve is connected to the outer side of the connecting seat, and a positioning cam is rotatably connected to the inner side of the guide sleeve. The positioning cam corresponds to the positioning groove. By moving the positioning cam along the positioning groove, the guide sleeve drives the connecting seat and the bending guide shaft to the bending portion of the protective sleeve. When the conductive core, insulating outer sheath, and protective sleeve bend, the surfaces of the protective sleeve and the bending guide shaft come into contact, and the bending guide shaft can rotate on the connecting seat. The protective sleeve not only protects the conductive core and insulating sheath from damage caused by the external environment, but also, because it is made of soft and wear-resistant material, it can adapt to frequent bending and movement of the sensor cable. Furthermore, the reinforcing ribs enhance the strength and rigidity of the protective sleeve, while structures such as the bending guide shaft guide the deformation direction of the sensor cable during bending and ensure uniform deformation, reducing the impact of bending stress on the sensor cable. This prevents wire breakage or sheath damage, which could affect the normal operation of the sensor and data transmission.

[0009] Preferably, each end of the curved guide shaft is rotatably connected to a bolt, and the bolt is threadedly connected to the connecting seat. The curved guide shaft can rotate on the bolt, and is thus connected to the connecting seat via the bolt.

[0010] Preferably, a washer is fitted onto the surface of the bolt, and the washer fits snugly against the connecting seat. When the bolt and connecting seat are connected, the washer improves the reliability of the connection and the stability of the structure.

[0011] Preferably, a nut is provided on the upper surface of the gasket, and the nut is threadedly connected to the bolt. Adding a nut to the bolt ensures the stability of the threaded connection between the bending guide shaft and the bolt, and also facilitates replacement of the bending guide shaft on the connecting seat after long-term use and severe wear.

[0012] Preferably, the inner surface of the guide sleeve is uniformly provided with guide grooves, and the positioning cam is located in the inner cavity of the guide groove. The positioning cam is rotatably connected to the positioning groove. When the guide sleeve moves along the surface of the protective sleeve, the positioning cam rotates in the inner cavity of the positioning groove and moves along the positioning groove, thereby reducing the friction between the guide sleeve and the protective sleeve during the movement, avoiding accelerated wear of the protective sleeve, and extending the service life of the protective sleeve.

[0013] Preferably, the outer surface of the curved guide shaft is polished smooth, and the surface of the curved guide shaft is in close contact with the surface of the protective sleeve. The protective sleeve can be fitted with the curved guide shaft.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a flexible bending protection structure for sensor cables, which has the following advantages:

[0016] The flexible bending protection structure of this sensor cable uses a positioning cam that moves along a positioning groove. This allows the guide sleeve to move the connecting seat and bending guide shaft to the bending section of the protective sleeve. When the conductive core, insulation sheath, and protective sleeve bend, the surfaces of the protective sleeve and the bending guide shaft come into contact, while the bending guide shaft can rotate on the connecting seat. This design not only protects the conductive core and insulation sheath from environmental damage through the protective sleeve, but also enhances the strength and rigidity of the protective sleeve through reinforcing ribs. Simultaneously, the bending guide shaft and other structures guide the deformation direction of the sensor cable during bending, ensuring uniform deformation and reducing the impact of bending stress on the sensor cable. This prevents wire breakage or sheath damage, which could affect the normal operation of the sensor and data transmission. Attached Figure Description

[0023] 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.

[0024] This utility model provides a technical solution: a flexible bending protection structure for a sensor cable, comprising a conductive core 1, an insulating outer sheath 2, a protective sleeve 3, a reinforcing rib 4, a positioning groove 5, a bending guide shaft 6, a bolt 7, a washer 8, a nut 9, a connecting seat 10, a guide sleeve 11, a guide groove 12, and a positioning cam 13. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The conductive core 1 is connected to an insulating outer sheath 2, and a protective sleeve 3 is fitted over the surface of the insulating outer sheath 2. Reinforcing ribs 4 are evenly distributed within the inner cavity of the protective sleeve 3, and positioning grooves 5 are evenly distributed on the surface of the protective sleeve 3. A bending guide shaft 6 is added to the outer side of the protective sleeve 3, and a connecting seat 10 is rotatably connected to the end of the bending guide shaft 6. A guide sleeve 11 is connected to the outer side of the connecting seat 10, and a positioning cam 13 is rotatably connected to the inner side of the guide sleeve 11. The positioning cam 13 corresponds to the positioning groove 5. The positioning cam 13 moves along the positioning groove 5, causing the guide sleeve 11 to move the connecting seat 10 and the bending guide shaft 6 to the bending portion of the protective sleeve 3. When the conductive core 1, insulating outer sheath 2, and protective sleeve 3 are bent, the surfaces of the protective sleeve 3 and the bending guide shaft 6 come into contact, and the bending guide shaft 6 can rotate on the connecting seat 10. The protective sleeve 3 not only protects the conductive core 1 and the insulating sheath 2 from damage by the external environment, but also, because the protective sleeve 3 is made of soft and wear-resistant material, it can adapt to the frequent bending and movement of the sensor cable. Furthermore, the reinforcing ribs 4 enhance the strength and rigidity of the protective sleeve 3. At the same time, the bending guide shaft 6 and other structures guide the deformation direction of the sensor cable during the bending process and guide the sensor cable to deform evenly during the bending process, reducing the impact of bending stress on the sensor cable. This avoids the phenomenon of wire breakage or sheath damage, which would affect the normal operation of the sensor and data transmission.

[0025] Please see Figure 4Each end of the bending guide shaft 6 is rotatably connected to a bolt 7, and the bolt 7 is threadedly connected to the connecting seat 10. The bending guide shaft 6 can rotate on the bolt 7, and thus connect to the connecting seat 10 through the bolt 7. A washer 8 is fitted on the surface of the bolt 7, and the washer 8 fits snugly against the connecting seat 10. After the bolt 7 and the connecting seat 10 are connected, the washer 8 can improve the reliability of the connection and the stability of the structure. A nut 9 is added to the upper surface of the washer 8, and the nut 9 is threadedly connected to the bolt 7. Adding a nut 9 to the bolt 7 can ensure the stability of the threaded connection between the bending guide shaft 6 and the bolt 7, and at the same time facilitate the replacement operation of the bending guide shaft 6 on the connecting seat 10 after long-term use and severe wear.

[0026] Please see Figure 5 The guide sleeve 11 has guide grooves 12 evenly distributed on its inner side, and the positioning cam 13 is located in the inner cavity of the guide groove 12. The positioning cam 13 is rotatably connected to the positioning groove 5. When the guide sleeve 11 moves along the surface of the protective sleeve 3, the positioning cam 13 rotates in the inner cavity of the positioning groove 5 and moves along the positioning groove 5, thereby reducing the friction between the guide sleeve 11 and the protective sleeve 3 during the movement, avoiding accelerated wear of the protective sleeve 3, and extending the service life of the protective sleeve 3.

[0027] Please see Figure 1 The outer surface of the curved guide shaft 6 is polished smooth, and the surface of the curved guide shaft 6 is tightly fitted with the surface of the protective sleeve 3. The protective sleeve 3 can be fitted with the curved guide shaft 6.

[0028] This solution: The positioning cam 13 moves along the positioning groove 5, causing the guide sleeve 11 to move the connecting seat 10 and the bending guide shaft 6 to the bending part of the protective sleeve 3. When the conductive core 1, the insulating outer sheath 2, and the protective sleeve 3 are bent, the surfaces of the protective sleeve 3 and the bending guide shaft 6 come into contact, and the bending guide shaft 6 can rotate on the connecting seat 10. The bending guide shaft 6 can rotate on the bolt 7, and is then connected to the connecting seat 10 through the bolt 7. A washer 8 and a nut 9 are sequentially connected to the bolt 7.
