Description

Technical Field

[0001] This invention relates to the field of control cable technology, specifically to an oil-resistant and interference-resistant computer control cable for industrial automation. Background Technology

[0002] Oil-resistant and interference-resistant computer control cables for industrial automation are signal transmission cables specifically designed for harsh industrial environments such as high electromagnetic interference, oil contamination, and dynamic motion. They are mainly used to connect industrial computers, PLCs, DCS systems, and field sensors, actuators, servo drives, and other equipment to ensure high-reliability transmission of control signals and data.

[0003] In Chinese patent application number CN202022633133.6, entitled "An Anti-interference Computer Control Cable", the anti-interference computer control cable ensures that the conductors do not interfere with each other through the anti-interference layer, and guarantees that each conductor can stably transmit electrical energy or signals independently; the shielding layer can shield external electromagnetic fields and other factors, prevent external electromagnetic fields and other factors from affecting the transmission of electrical energy or signals, and ensure that the electrical energy or signals in the cable can be transmitted stably. The computer control cables in this patent and existing technologies have poor compressive strength when subjected to external forces, and cannot effectively protect the shielding layer on the outside of each conductor. When the shielding layer is damaged, the cable's shielding effect is poor, its anti-interference ability is weakened, and in the event of a fire, the cable cannot effectively guarantee the energization stability of each conductor, cannot provide workers with a longer emergency operation time, and cannot minimize economic losses in the event of a fire. Summary of the Invention

[0004] This invention provides an oil-resistant and interference-resistant computer control cable for industrial automation, which can effectively solve the problems of poor pressure resistance, inability to effectively protect the shielding layer on the outside of each conductor, weakened interference resistance, and inability to provide workers with a long emergency operation time in the event of a fire, resulting in significant economic losses in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oil-resistant and interference-resistant computer control cable for industrial automation, comprising six conductors, with each pair of conductors forming a group, and a shielding protection component provided on the outside of the conductors, the shielding protection component including an inner shielding layer; The conductor is wrapped with an inner shielding layer, the inner shielding layer is wrapped with an insulating layer, and two adjacent insulating layers are wrapped with inner protective pads. There are three inner protective pads, and the inner protective pads are wrapped with an outer shielding sleeve. Three outer shielding sleeves are embedded in the center of a triangular tube.

A buffer cavity is provided inside the arc-shaped spacer. A central flexible tube is embedded in the center of the triangular tube. A triangular rib is wrapped around the outside of the central flexible tube. A triangular spring is sleeved on the outside of the triangular rib inside the triangular tube.

[0006] According to the above technical solution, the outer side of the arc-shaped spacer is provided with multiple bends at equal intervals, and the outer shielding sleeve and the outer side of the arc-shaped spacer are wrapped with mica tape.

[0007] According to the above technical solution, a peripheral hose is embedded in the center of the buffer cavity, and multiple buffer frames are connected to the outside of the peripheral hose by several connecting arc plates at equal intervals. The outer side of the buffer frame is in contact with the inner wall of the buffer cavity.

[0008] According to the above technical solution, the mica tape is wrapped with an outer protective pad, the outer protective pad is wrapped with an inner protective sleeve, and the inner protective sleeve is wrapped with a protective sponge.

[0009] According to the above technical solution, the protective sponge has a protective cavity inside, which is evenly distributed on the outside of the inner sheath, and a wave spring is embedded inside the protective cavity.

[0010] According to the above technical solution, one end of the wave spring is connected to a male connector, and the other end of the wave spring is connected to a female connector. Two adjacent wave springs are connected end to end through the male and female connectors. The male connector is embedded inside the adjacent female connector and is fixed by connecting screws.

[0011] According to the above technical solution, the protective sponge is wrapped with an armor belt on the outside, the armor belt is wrapped with an outer sheath, and two annular air boxes are sleeved at both ends of the outer sheath. The inner side of the annular air boxes is connected to the central hose and the outer peripheral hose through several stainless steel hoses.

[0012] According to the above technical solution, a connector protection component is provided at one end of the outer sheath, and the connector protection component includes a tripod. A tripod is provided at the center of one end of the outer sheath. An arc-shaped spring is connected to the side of the tripod by two back-to-back isolation arc plates. Multiple semi-circular grooves are opened on the surface of the arc-shaped spring. Fixed tubes are connected to both ends of the arc-shaped spring. The outer sheath has two semi-circular arc plates fixed on one side. The two semi-circular arc plates are fixedly connected by bolts. The inner wall of the semi-circular arc plate is in contact with the outer side of the outer sheath. Three connecting plates are welded to the inner side of the semi-circular arc plate. A connecting frame is welded to the top of the connecting plate. The connecting frame is fixedly connected to the corresponding fixing pipe by fixing bolts. The outer side of the semi-circular plate is wrapped with a sponge pad, and the outer side of the sponge pad is fitted with a heat shrink tube. The inner sides of both ends of the heat shrink tube are attached to the outer side of the outer sheath.

[0013] According to the above technical solution, two docking frames are symmetrically fixed at both ends of the heat shrink tubing, and fixing ears are provided on both sides of the docking frames. Adjacent docking frames are connected and fixed by fixing ears and bolts.

[0014] According to the above technical solution, a number of hooks are provided on the outer side of the docking frame, and a serpentine spring is connected between two opposite hooks. Hooks are connected to both ends of the serpentine spring, and the hooks are hooked to the corresponding hooks.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with shielding protection components, the triangular tubes and arc-shaped spacers are made of ceramicized silicone rubber. The arc-shaped spacers can separate each outer shielding sleeve. When the cable is subjected to external pressure, it prevents direct friction between the outer shielding sleeves, avoiding damage to the outer shielding sleeves due to friction, and ensuring the stability of electrical shielding. In addition, the triangular tubes and arc-shaped spacers form a hard ceramic shell after combustion. The outer shielding sleeves and arc-shaped spacers are wrapped with mica tape. In the event of a fire, the triangular tubes, arc-shaped spacers and mica tape work together to give each group of conductors an independent separation zone, so that the cable maintains circuit integrity in the fire and has the ability to control the power supply even when the cable is burning. This provides computer control personnel with sufficient emergency operation time, allows the computer enough time to save data, and minimizes economic losses. The mica tape is wrapped with an outer protective pad, and the inner and outer protective pads are made of thermally conductive silicone pads, which have good elasticity and thermal conductivity. An outer peripheral hose is embedded in the center of the buffer cavity. Multiple buffer frames are connected to the outside of the outer peripheral hose through several connecting arc plates at equal intervals. When the arc-shaped spacer is squeezed, the buffer frames and connecting arc plates buffer the external force through elastic deformation. Combined with the energy absorption buffer of the inner and outer protective pads, the computer control cable has strong compressive strength. Triangular springs are wrapped around the outside of the triangular ribs. The triangular springs have good elastic expansion and contraction capabilities as well as good elastic support capabilities, making the cable less prone to deformation, ensuring the mechanical support strength of the cable, and further improving the cable's compressive strength. By passing air through the central and outer flexible hoses, the heat from the center and periphery of the cable is carried away by the airflow, which greatly improves the heat dissipation performance of the cable and prevents the conductor temperature from being too high, thus affecting the transmission of power signals. The cable has good operational stability. The protective sponge can block the heat from the outside of the cable and prevent the external heat from affecting the normal operation of the conductor. By solving both internal and external factors, the cable ensures the operating temperature of the cable and fully guarantees the operational stability of the cable. Furthermore, in the event of a fire, when the triangular rib is damaged by the fire, the diffuser holes at the damaged locations are exposed. By supplying inert gas into the central hose, the inert gas diffuses outward from the exposed diffuser holes, diluting the oxygen concentration and reducing the flame burning speed, thus further improving the flame retardancy of the cable. The cable has good flame retardant performance.

[0016] 2. Equipped with a joint protection component, when connecting two cables, the tripod is installed at the connection position. After each conductor is connected, the conductor is inserted between two opposing isolation arc plates. The isolation arc plates separate each group of conductors, ensuring the operational stability of each group of conductors. The heat shrink tubing is clamped at both ends by the mating bracket to ensure the tight fit between the heat shrink tubing and the outer sheath, ensuring the sealing of the cable connection and good stability of the cable connection. When the cable connection is subjected to external pressure, the elasticity of the serpentine spring and sponge pad provides initial buffering and absorption of the external force. The tripod, insulating arc plate, arc-shaped spring, and semi-circular arc plate are made of stainless steel. When the semi-circular arc plate is subjected to force, the insulating arc plate and arc-shaped spring undergo elastic deformation to buffer the external force, providing better protection for the cable connection and fully ensuring the connection stability of the cable connection.

[0017] In summary, the shielding protection assembly incorporates triangular springs and corrugated springs. When the cable is subjected to external bending forces, the elastic deformation of the corrugated springs and triangular springs improves the cable's resistance to pressure and bending. The joint protection assembly utilizes the elastic force of serpentine springs to ensure good resistance to pressure and bending at the cable joint. The two components work together to enhance the overall anti-interference capability of the cable. Furthermore, the cable's outer sheath is made of polyurethane, which has excellent oil resistance, resulting in strong oil resistance and a longer service life. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-12 As shown, this invention provides a technical solution for an oil-resistant and interference-resistant computer control cable for industrial automation, including a conductor 1. Six conductors 1 are arranged, with two conductors 1 forming a group. A shielding protection component 2 is arranged on the outside of the conductor 1. The shielding protection component 2 includes an inner shielding layer 201, an insulation layer 203, an inner protective pad 204, an outer shielding sleeve 205, a mica tape 206, a triangular tube 207, an arc-shaped spacer 208, a bend 209, a buffer cavity 210, a central flexible tube 211, a triangular rib 212, a triangular spring 213, a diffuser hole 214, an escaping hole 215, an outer peripheral flexible tube 216, a connecting arc plate 217, a buffer frame 218, an outer protective pad 219, an inner sheath 220, a protective sponge 221, a protective cavity 222, a corrugated spring 223, a male connector 224, a female connector 225, a connecting screw 226, an armor tape 227, an outer sheath 228, and an annular air box 229. The conductor 1 is wrapped with an inner shielding layer 201, the inner shielding layer 201 is wrapped with an insulating layer 203, and the outer sides of two adjacent insulating layers 203 are wrapped with inner protective pads 204. There are three inner protective pads 204, and the outer sides of the inner protective pads 204 are wrapped with an outer shielding sleeve 205. Three outer shielding sleeves 205 are embedded in the center of a triangular tube 207. An arc-shaped spacer 208 is connected to the triangular side of the triangular tube 207. The outer shielding sleeve 205 is located between two adjacent arc-shaped spacers 208. The triangular tube 207 and the arc-shaped spacer 208 are made of ceramicized silicone rubber. Ceramicized silicone rubber has good elasticity at room temperature and forms a hard ceramic shell after combustion, maintaining structural integrity and preventing molten droplets. Multiple bends 209 are evenly spaced on the outer side of the arc-shaped spacer 208. When the cable is bent, the bends 209 can provide bending space for the cable, allowing the cable to bend smoothly. Mica tape 206 is wrapped around the outer side of the outer shielding sleeve 205 and the arc-shaped spacer 208. Mica tape 206 has a fireproof function and excellent high temperature resistance. When the outer material of the cable is burned, mica tape 206 can form a dense ceramic barrier to protect the internal conductor 1 of the cable. The arc-shaped spacer 208 has a buffer cavity 210 inside, and an outer peripheral hose 216 is embedded in the center of the buffer cavity 210. Multiple buffer frames 218 are connected to the outer side of the outer peripheral hose 216 at equal intervals through several connecting arc pieces 217. The outer side of the buffer frame 218 is in contact with the inner wall of the buffer cavity 210. When the arc-shaped spacer 208 is compressed, the buffer frame 218 and the connecting arc pieces 217 buffer the external force through elastic deformation, thereby improving the compressive strength of the cable. At the same time, the outer peripheral hose 216 is made of stainless steel, and the connecting arc pieces 217 and the buffer frame 218 are also made of stainless steel, which has good elasticity and thermal conductivity. When air is introduced into the outer peripheral hose 216, the air can quickly carry away the heat on the outer peripheral hose 216, the connecting arc pieces 217 and the buffer frame 218. Under the action of heat conduction, the heat generated on the cable conductor 1 is carried away. A central flexible tube 211 is embedded in the center of the triangular tube 207. A triangular rib 212 is wrapped around the outside of the central flexible tube 211. A triangular spring 213 is sleeved inside the triangular tube 207 on the outside of the triangular rib 212. The central flexible tube 211 is also made of stainless steel, and the triangular rib 212 is also made of thermally conductive silicone pad material, which has good elasticity and thermal conductivity. The triangular spring 213 is surrounded by the outside of the triangular rib 212 and is made of stainless steel. When air is introduced into the central flexible tube 211, the central flexible tube 211, the triangular rib 212 and the triangular spring 213 can be cooled by heat conduction. Multiple diffusion holes 214 are evenly spaced on the surface of the central flexible tube 211, and multiple vent holes 215 are opened on the outer surface of the triangular tube 207. The heat generated by the conductor 1 can enter the interior of the triangular tube 207 through the vent holes 215. When air is introduced into the central flexible tube 211, the heat can be carried away by heat conduction, thereby improving the heat dissipation performance of the cable. The outer protective pad 219 is wrapped around the mica tape 206. The inner protective pad 204 and the outer protective pad 219 are made of thermally conductive silicone pad material, which has good elasticity and thermal conductivity. The heat generated by the conductor 1 can be conducted to the outer protective pad 219 through the inner protective pad 204. The heat on the outer protective pad 219 can enter the buffer cavity 210 through the bend 209. When air is introduced into the outer peripheral hose 216, it can quickly cool down the outer protective pad 219. The outer protective pad 219 is wrapped with an inner sheath 220. The outer sheath 220 is wrapped with a protective sponge 221. The protective sponge 221 has a protective cavity 222 inside. The protective cavity 222 is evenly distributed on the outside of the inner sheath 220. The protective cavity 222 is embedded with a corrugated spring sheet 223. The protective sponge 221 is a flame-retardant sponge with flame-retardant, heat insulation and shock absorption properties. The protective sponge 221 can block the heat from the outside of the cable and prevent the external heat from affecting the normal operation of the conductor 1. One end of the wave spring 223 is connected to a male connector 224, and the other end is connected to a female connector 225. Adjacent wave springs 223 are connected end-to-end via the male connector 224 and the female connector 225. The male connector 224 is embedded inside the adjacent female connector 225 and secured by a connecting screw 226. The embedding of the male connector 224 inside the female connector 225 facilitates the connection of adjacent wave springs 223. An armor strap 227 is wrapped around the outside of the protective sponge 221, and the outside of the armor strap 227 is covered with an outer... The outer sheath 228 is made of polyurethane, which has good oil resistance. Two annular air boxes 229 are sleeved on both ends of the outer sheath 228. The inner side of the annular air box 229 is connected to the central hose 211 and the outer peripheral hose 216 through several stainless steel hoses. The stainless steel hoses pass through the corresponding structure on the outside of the cable and are connected to the inner central hose 211 and the outer peripheral hose 216. When filtered clean air is delivered into one annular air box 229, the air can flow in the hose and be ejected from the other annular air box 229. One end of the outer sheath 228 is provided with a joint protection component 3, which includes a tripod 301, an isolation arc plate 302, an arc-shaped spring 303, a semi-circular groove 304, a fixing tube 305, a semi-circular arc plate 306, a connecting plate 307, a connecting frame 308, a fixing bolt 309, a sponge pad 310, a heat shrink tubing 311, a docking frame 312, a fixing ear 313, a hook ear 314, a serpentine spring 315, and a hook 316. A tripod 301 is provided at the center of one end of the outer sheath 228. An arc-shaped spring piece 303 is connected to the triangular side of the tripod 301 through two back-to-back isolation arc pieces 302. Multiple semi-circular grooves 304 are opened on the surface of the arc-shaped spring piece 303. Fixed tubes 305 are connected to both ends of the arc-shaped spring piece 303. The outer sheath 228 has two semi-circular arc plates 306 fixed on one side. The two semi-circular arc plates 306 are fixedly connected by bolts. The inner wall of the semi-circular arc plate 306 fits against the outer side of the outer sheath 228. Three connecting plates 307 are welded to the inner side of the semi-circular arc plate 306. A connecting frame 308 is welded to the top of the connecting plate 307. The connecting frame 308 is fixedly connected to the corresponding fixed pipe 305 by fixing bolts 309. The outer side of the semi-circular plate 306 is wrapped with a sponge pad 310, and a heat shrink tube 311 is sleeved on the outer side of the sponge pad 310. The inner sides of both ends of the heat shrink tube 311 are attached to the outer side of the outer sheath 228. Two docking brackets 312 are symmetrically fixed at both ends of the heat shrink tube 311. Fixing ears 313 are provided on both sides of the docking brackets 312. Two adjacent docking brackets 312 are connected and fixed by fixing ears 313 and bolts. The docking brackets 312 can clamp the two ends of the heat shrink tube 311 to ensure the tightness of the fit between the heat shrink tube 311 and the outer sheath 228 and ensure the sealing of the cable connection. The outer side of the connector 312 is provided with several hanging ears 314. A serpentine spring 315 is connected between two opposite hanging ears 314. Hooks 316 are connected to both ends of the serpentine spring 315. The hooks 316 are hooked to the corresponding hanging ears 314. The connection between the hooks 316 and the hanging ears 314 facilitates the installation of the serpentine spring 315. Utilizing the elasticity of the serpentine spring 315 and the sponge pad 310, when the cable connection point is subjected to external pressure, the connection stability at the connection point is ensured through the buffering effect of the serpentine spring 315 and the sponge pad 310.

[0022] The working principle and usage process of this invention: The triangular tube 207 and the arc-shaped spacer 208 are made of ceramicized silicone rubber. Ceramicized silicone rubber has good elasticity at room temperature. The arc-shaped spacer 208 can separate each outer shielding sleeve 205, preventing direct friction between the outer shielding sleeves 205 when the cable is subjected to external pressure. This avoids damage to the outer shielding sleeves 205 due to friction, ensuring the stability of the electrical shielding. Furthermore, after combustion, the triangular tube 207 and the arc-shaped spacer 208 form a hard, durable ceramic shell, maintaining structural integrity and preventing molten droplets. The outer shielding sleeves 205 and the arc-shaped spacer... The outer side of 208 is wrapped with mica tape 206. Mica tape 206 has fireproof properties and excellent high temperature resistance. When the outer material of the cable is burned, mica tape 206 can form a dense ceramic-like barrier. In the event of a fire, the triangular tube 207, the arc-shaped spacer 208 and the mica tape 206 work together to give each group of conductors 1 an independent separation zone, so that the cable maintains circuit integrity in the fire and has the ability to control the power supply even when the cable is burning. This provides computer control personnel with sufficient emergency operation time and allows the computer to save data in time, reducing economic losses. The mica tape 206 is wrapped with an outer protective pad 219. The inner protective pad 204 and the outer protective pad 219 are made of thermally conductive silicone pads, which have good elasticity and thermal conductivity. An outer peripheral hose 216 is embedded in the center of the buffer cavity 210. Multiple buffer frames 218 are connected at equal intervals to the outer side of the outer peripheral hose 216 through several connecting arc pieces 217. When the arc-shaped spacer 208 is squeezed, the buffer frame 218 and the connecting arc pieces 217 buffer the external force through elastic deformation. Combined with the energy absorption buffer of the inner protective pad 204 and the outer protective pad 219, the computer control cable has strong compressive strength. The triangular rib 212 is also made of thermally conductive silicone pad material, which has good elasticity and thermal conductivity. The triangular spring 213 surrounds the outside of the triangular rib 212. The triangular spring 213 is made of stainless steel and has a triangular cross section. The spring has good elastic expansion and contraction capabilities as well as good elastic support capabilities, making the cable less prone to deformation, ensuring the mechanical support strength of the cable, and further improving the cable's compressive strength. The inner sheath 220 is wrapped with a protective sponge 221. The protective sponge 221 has a protective cavity 222 inside, and a corrugated spring 223 is embedded inside the protective cavity 222. The corrugated spring 223 has good elasticity. When the cable is bent by external force, the corrugated spring 223 and the triangular spring 213 undergo elastic deformation. When the bending force is removed, the corrugated spring 223 and the triangular spring 213 rebound, improving the cable's bending resistance and making the cable more resilient. The central flexible hose 211 is made of stainless steel. When filtered clean air is supplied into an annular air box 229, the air can flow inside the central flexible hose 211 and be ejected from another annular air box 229. Through heat conduction, this cools the central flexible hose 211, the triangular ribs 212, and the triangular spring 213. Multiple diffuser holes 214 are evenly spaced on the surface of the central flexible hose 211, and multiple vent holes 215 are opened on the outer surface of the triangular tube 207. Heat generated by the conductor 1 can pass through the vent holes 215 into the triangular tube 207. When air is introduced into the central flexible hose 211, through heat conduction, the heat is carried away, improving the cable's heat dissipation performance. The outer flexible hose 216 is made of stainless steel, and the connecting arc plate 217 and the buffer frame 218 are also made of stainless steel, possessing good elasticity and thermal conductivity. When filtered clean air is supplied into an annular air box 229... When clean air is present, the air can flow inside the outer circumferential hose 216. The flowing air can quickly remove the heat from the outer circumferential hose 216, the connecting arc plate 217, and the buffer frame 218. Under the action of heat conduction, the heat generated on the cable conductor 1 is removed. When the cable's own operating temperature is high, the heat from the center and periphery of the cable is removed by the flow of air through the central hose 211 and the outer circumferential hose 216, which fully improves the heat dissipation performance of the cable and avoids the conductor 1 from being too hot and affecting the transmission of power signals. The cable has good operating stability. The protective sponge 221 is a flame-retardant sponge with flame-retardant, heat insulation, and shock absorption properties. The protective sponge 221 can block the heat from the outside of the cable and prevent the external heat from affecting the normal operation of the conductor 1. By solving both internal and external causes, the cable's operating temperature is guaranteed, and the operating stability of the cable is fully guaranteed. Furthermore, in the event of a fire, when the triangular rib 212 is damaged by the fire, the diffuser hole 214 at the damaged location is exposed. By supplying inert gas into the central hose 211, the inert gas diffuses from the exposed diffuser hole 214 to the surrounding area, thereby reducing the flame burning speed by diluting the oxygen concentration and further improving the flame retardant capability of the cable. The cable has good flame retardant performance. When connecting two cables, install the tripod 301 at the connection position, aligning it with the triangular tube 207. After each conductor 1 is connected, insert the conductor 1 between two opposing insulating arc plates 302. The insulating arc plates 302 separate each group of conductors 1, ensuring the operational stability of each group. After fixing the fixing tube 305 and the connecting bracket 308 with fixing bolts 309, use bolts to connect and fix the two semi-circular arc plates 306. After the semi-circular arc plates 306 are fixed, Next, place the sponge pad 310 on the outside of the semi-circular plate 306, and then use the heat shrink tubing 311 to seal the sponge pad 310 and the connection point of the two cables. After sealing, install the docking frame 312. The docking frame 312 can clamp the two ends of the heat shrink tubing 311 to ensure the tight fit between the heat shrink tubing 311 and the outer sheath 228 and to ensure the sealing of the cable connection. The serpentine spring 315 has hooks 316 connected to both ends. The hooks 316 are hooked to the corresponding hook ears 314. Then install the serpentine spring 315. When the cable connection is subjected to external pressure, the elasticity of the serpentine spring 315 and the sponge pad 310 provides initial buffering and absorption of the external force. The tripod 301, insulating arc plate 302, arc-shaped spring 303, and semi-circular arc plate 306 are made of stainless steel. When the semi-circular arc plate 306 is subjected to force, the insulating arc plate 302 and the arc-shaped spring 303 undergo elastic deformation, buffering the external force and providing better protection for the cable connection, thus fully ensuring the connection stability of the cable connection.
