Description

Technical Field

[0001] This invention belongs to the field of cable technology, specifically relating to a high-shield computer control cable. Background Technology

[0002] Computer control cables belong to the category of electrical equipment cables. High-shielded cables are transmission lines that reduce electromagnetic interference through a metallic shielding layer. Their core structure includes a conductor, insulation layer, shielding layer, and sheath layer. The conductor, typically made of copper or aluminum, transmits current or signals. An insulation layer wraps around the conductor, made of materials such as polyethylene (PE) or polyvinyl chloride (PVC). The shielding layer is a critical component, employing a metallic braided layer (copper / tinned copper) or aluminum foil. Some high-end models use double-layer composite shielding (aluminum foil + copper braided mesh), typically exceeding 38μm in thickness to enhance high-frequency shielding. The sheath layer provides outer protection, made of materials such as polyvinyl chloride (PVC) or polyurethane (PU), improving corrosion resistance, cold resistance, and flexibility.

[0003] Existing metal-shielded cables need to connect a lot of electrical equipment, which complicates the wiring and results in a messy cable distribution on site. Furthermore, due to the external metal sheath and the bundled installation of the cables, heat dissipation is easily impaired. Summary of the Invention

[0004] The purpose of this invention is to provide a high-shield computer control cable with a simple structure, high protection and shielding, which can bundle multiple cables together, making it easy to assemble and disassemble the cables. It is also equipped with a detachable heat dissipation mechanism with a temperature sensing device, which has good heat dissipation performance and is suitable for widespread application.

[0005] This invention provides the following technical solution: a high-shield computer control cable, comprising an outer sheath and a cable, wherein the outer sheath is made of polyethylene, the cable is wrapped with an aluminum foil protective layer, the outer sheath has multiple adjacent sections, the central cross-section of which is circular, the cable passes through the middle of the outer sheath and is attached to it, the outer sheath is located on both sides of the cable as side cavities, and the adjacent side walls of the outer sheath are side walls; The side walls on both sides of the outer sheath are respectively provided with a docking groove and a raised wall. The docking groove and the raised wall are opposite in position and shape. The bottom of the docking groove is provided with a through frame hole on both sides. The two ends of the raised wall are fixed with outward protruding clips corresponding to the through frame holes. The two clips are symmetrical to each other and have a first inclined sliding surface on the outside. The clips are provided with grooves that fasten to the side wall. The middle part of the docking groove and the protruding wall is provided with a concave snap-fit ​​groove. The snap-fit ​​groove is equipped with a heat dissipation part. The upper part of the heat dissipation part is an air intake grille. The two sides of the heat dissipation part are connected to the side cavity and are provided with through heat dissipation grilles. An electric fan is mounted on the upper side of the heat dissipation grille through support bars inside the heat dissipation part. An internal wiring is embedded in the upper corner of the side cavity through the eave frame. The eave frame is fixedly provided with a power connection groove at the snap-fit ​​groove. The power connection groove has the same circuit as the internal wiring. The power connection of the electric fan is a retractable power connector, which is connected to the power connection groove.

[0006] Furthermore, force-bearing buttons are fixedly provided on both sides of the upper end of the heat dissipation housing, and the locking strip is provided with an inclined second sliding surface at the groove. The second sliding surface is connected to the side wall of the groove, and the inclination of the second sliding surface is less than that of the first sliding surface.

[0007] Furthermore, the cable comprises, from the outside to the inside, an inner sheath, an armor layer, an outer flame-retardant layer, an outer shielding layer, and a wrapping layer. The outer shielding layer is composed of an aluminum foil protective layer, and the wrapping layer contains multiple cable core units.

[0008] Furthermore, the heat dissipation unit has a telescopic cavity at the corresponding electrical connection slot. The telescopic cavity is made of an insulating sleeve. The electrical connection head is a cylinder with a round head at the front end, which extends through the telescopic cavity and connects to the electrical connection slot. The electrical connection head is fixedly provided with a connecting block inside the telescopic cavity. The connecting block has a connecting wire on its lower side, which extends downward and is embedded in the support strip to connect with the electric fan. A support spring is fixedly provided on the side of the connecting block away from the electrical connection head, and the other end of the support spring rests against the inner wall of the telescopic cavity.

[0009] Furthermore, the outer sheath consists of multiple parallel strips, and the outer sheath has various models that are bent at different angles.

[0010] Furthermore, a temperature control switch is installed on the connecting wire connected to the connector. The two bimetallic strips on the temperature control switch are in a free state and are disconnected from each other. When the temperature rises to the operating temperature value, the thermal expansion block connected to the bimetallic element is heated and generates internal stress, causing it to act quickly, close the contacts, and the circuit is connected.

[0011] The beneficial effects of this invention are: simple structure, high protection and shielding, ability to bundle and assemble multiple cables, convenient assembly and disassembly of cables, and equipped with a detachable heat dissipation mechanism with a temperature sensing device, resulting in good heat dissipation, as detailed below: (1) The present invention is provided with an outer sheath, in which the cable is sleeved. The outer sheath provides support and protection. For bundled cables, the outer sheaths can be spliced ​​together. When docking, the sides of the two outer sheaths are placed opposite each other, the protruding wall is aligned with the docking groove and pressed down, and the first inclined sliding surface of the clip is squeezed, causing the clip to undergo elastic deformation and pass through the through frame hole and be inserted into the groove of the clip. The protruding wall and the docking groove are then docked and closed, the two outer sheaths are connected, and the cable is arranged in a regular manner.

[0012] (2) The present invention is provided with a heat dissipation part. After the outer sheaths are connected, a snap-fit ​​groove with the opening facing upward is formed at the connection point. The heat dissipation part is installed at the snap-fit ​​groove according to specific needs. When the heat dissipation part is pressed down, the contact head on it is squeezed into the telescopic cavity and popped out when it moves to the contact groove. The electric fan of the heat dissipation part is powered on. The electric fan draws air from the upper air intake grille and discharges it into the heat dissipation grilles on both sides. The heat dissipation grilles are connected to the side cavities on both sides of the cable to dissipate heat from the cable. A temperature control switch can be set in the heat dissipation part. The two bimetallic strips on the temperature control switch are in an open state. When the temperature rises to a certain height value, the thermal expansion block connected to the bimetallic element is heated and generates internal stress and expands, closing the contact and connecting the electric fan circuit, so that the electric fan automatically turns on to dissipate heat when the temperature is too high.

[0013] (3) The present invention is provided with a force button. When it is necessary to separate the outer sheath, the force button on both sides of the top of the heat dissipation part can be pressed and twisted to generate a separation force between the mating groove and the protruding wall. This force squeezes the second inclined sliding surface, causing the locking strip to undergo elastic deformation. The outer sheath can then be separated with the help of the strip-shaped outer shell of the heat dissipation part. Attached Figure Description

[0018] The structural features of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] See Figure 1 , 24. A high-shield computer control cable, comprising an outer sheath 1 and a cable 2. The outer sheath 1 is made of polyethylene. The cable 2 is wrapped with an aluminum foil protective layer. From the outside to the inside, the cable 2 includes an inner sheath, an armor layer, an outer flame-retardant layer, an outer shielding layer, and a wrapping layer. The outer shielding layer is made of aluminum foil for shielding protection. The wrapping layer has multiple cable core units. The outer sheath 1 has multiple adjacent cables with a circular cross-section in the middle for the cable 2 to pass through. The cable 2 passes through the middle of the outer sheath 1 and connects with... The outer sheath 1 is located on both sides of the cable 2 as a side cavity 3 for ventilation. The adjacent side wall of the outer sheath 1 is a side wall 4. The side walls 4 on both sides of the outer sheath 1 are respectively provided with a mating groove 5 and a raised wall 7. The mating groove 5 and the raised wall 7 are opposite in position and shape. The mating groove 5 is pressed into the raised wall 7 to close the two outer sheaths 1. The bottom of the mating groove 5 is provided with a through frame hole 6 on both sides. The two ends of the raised wall 7 are fixed with outward protruding retaining strips 16 corresponding to the through frame holes 6. The two retaining strips 16 are mutually opposite. The device is described as having a first inclined sliding surface 19 on its outer side. When the first inclined sliding surface 19 is compressed, the locking strip 16 undergoes elastic deformation and passes through the through frame hole 6. The locking strip 16 has a groove that fastens onto the side wall 4, fixing the mating groove 5 to the protruding wall. The middle of the mating groove 5 and the protruding wall 7 has a recessed locking groove 8. A heat dissipation part 11 is provided at the locking groove 8. Force buttons 15 are fixed on both sides of the upper end of the heat dissipation part 11 housing. The locking strip 16 has an inclined second inclined sliding surface 20 at the groove. The second inclined sliding surface 20 and the... The side wall 4 of the groove is connected. The inclination of the second inclined sliding surface 20 is less than that of the first inclined sliding surface 19, so that when the first inclined sliding surface 19 is squeezed, the locking strip 16 is more likely to produce elastic deformation. Press and twist the force buttons 15 on both sides of the top of the heat dissipation part 11. The connecting groove 5 and the protruding wall 7 generate a separation force, which squeezes the second inclined sliding surface 20 and helps to separate the outer sheath 1. The outer sheath 1 consists of multiple parallel strips. The outer sheath 1 has various models that can be bent at different angles, so that the cable 2 can be bent and laid.

[0020] See Figure 1-3 The upper part of the heat dissipation section 11 is an air intake grille 12. The two sides of the heat dissipation section 11 are connected to the side cavity 3 and are provided with through heat dissipation grilles 14. An electric fan 13 is mounted on the upper side of the heat dissipation grille 14 through the support bar 25 inside the heat dissipation section 11. The electric fan 13 draws air from the upper air intake grille 12 and discharges it into the heat dissipation grilles 14 on both sides. The heat dissipation grille 14 dissipates heat from the cable 2 at the side cavity 3. An internal wiring 10 is embedded in the upper corner of the side cavity 3 through the eave frame 9. The eave frame 9 is fixed with a power connection groove 21 at the snap-fit ​​groove 8. The power connection groove 21 has the same circuit as the internal wiring 10. The power connection of the electric fan 13 is a retractable power connector 18. The power connector 18 is connected to the power connection groove 21 to power the electric fan 13.

[0021] See Figure 1 , 35. The heat dissipation part 11 has a telescopic cavity 22 at the corresponding electrical connection slot 21. The telescopic cavity 22 is made of an insulating sleeve. The electrical connector 18 is a cylinder with a rounded front end, which extends through the telescopic cavity 22 and connects to the electrical connection slot 21. When the part of the heat dissipation part 11 exposed is squeezed, it can retract into the heat dissipation part 11. The electrical connector 18 is fixedly provided with a connecting block 23 inside the telescopic cavity 22. The connecting block 23 has a connecting wire on its lower side. The connecting wire has a bent section, which can be stretched when the connecting block 23 moves horizontally. The connecting wire extends downward and is embedded in the support strip 25 to connect to the electric fan 13, so that the electric fan 13 is connected to the internal wiring 10. The connecting block 23 is far from the electric fan 13. A support spring 24 is fixedly provided on one side of the connector 18, and the other end of the support spring 24 abuts against the inner wall of the telescopic cavity 22. The support spring 24 presses the connector 18 into the connector groove 21 when they are in opposite positions. A temperature control switch is provided on the connecting wire connected to the connector 18. The two bimetallic strips on the temperature control switch are in a free state and are disconnected from each other. When the temperature rises to the operating temperature value, the thermal expansion block connected to the bimetallic element is heated and generates internal stress, causing it to move quickly and close the contact. The circuit is connected, so that when the temperature rises, the thermal expansion block connected to the bimetallic element expands due to heat, so that the electric fan 13 automatically turns on to dissipate heat when the temperature is too high.

[0022] The high-shield computer control cable of the present invention has a simple structure, high protection and shielding performance, and can bundle multiple cables together for easy assembly and disassembly. It is also equipped with a detachable heat dissipation mechanism with a temperature sensing device, which has good heat dissipation performance and is suitable for widespread application.

[0023] For specific usage, please refer to... Figure 1 , 2 4. The cable 2 is encased in the outer sheath 1. For bundled cables, the outer sheaths 1 can be spliced ​​together. When connecting, the sides of the two outer sheaths 1 are placed opposite each other, the protruding wall 7 is aligned with the docking groove 5 and pressed down. The first inclined sliding surface 19 of the locking strip 16 is squeezed, causing the locking strip 16 to undergo elastic deformation and pass through the through frame hole 6. It is then inserted into the groove of the locking strip 16, which can close the protruding wall 7 and the docking groove 5. The two outer sheaths 1 are connected, and the cable 2 is arranged neatly. When it is necessary to separate the outer sheath 1, the force buttons 15 on both sides of the top of the heat dissipation part 11 can be pressed and twisted. The docking groove 5 and the protruding wall 7 generate a separation force, which squeezes the second inclined sliding surface 20, causing the locking strip 16 to undergo elastic deformation. With the help of the strip-shaped outer shell of the heat dissipation part 11, the outer sheath 1 is separated. Reference Figure 1 , 25. After the outer sheath 1 is connected, a snap-fit ​​groove 8 with the opening facing upwards is formed at the connection point. According to specific requirements, a heat dissipation part 11 is installed at the snap-fit ​​groove 8. When the heat dissipation part 11 is pressed down, the electrical connector 18 on it is squeezed into the telescopic cavity 22 and pops out when it moves to the electrical connector groove 21. The electric fan 13 of the heat dissipation part 11 is powered on. The electric fan 13 draws air from the upper air intake grille 12 and discharges it into the heat dissipation grilles 14 on both sides. The heat dissipation grilles 14 are connected to the side cavities 3 on both sides of the cable 2 to dissipate heat from the cable 2. A temperature control switch can be installed in the heat dissipation part 11. The two bimetallic strips on the temperature control switch are in an open state. When the temperature rises to a certain height value, the thermal expansion block connected to the bimetallic element is heated and expands due to internal stress, closing the contact and connecting the electric fan 13 circuit. When the temperature is too high, the electric fan 13 automatically turns on to dissipate heat.
