Description

Technical Field

[0001] The invention relates to the technical field of cable connectors, in particular to a steel wire braided rubber sheath connector with a cable. Background Art

[0002] In modern industry and technology, the performance and reliability of electrical connectors are crucial to ensure the stable operation of the system. Especially in industries such as power, communications, industrial automation, petroleum, chemical industry, and mining, electrical connectors not only need to withstand complex and changeable environmental conditions such as high temperature, high pressure, humidity, corrosion, etc., but also need to ensure the quality and stability of signal transmission. Therefore, steel wire braided rubber sheath connectors with cables came into being and became an indispensable key component in these fields. Traditional electrical connectors are often difficult to maintain long-term stable performance in harsh environments. For example, although ordinary rubber sheath connectors have certain insulation and protection functions, their protection capabilities are limited when facing high-intensity wear, tear or external impact. In addition, a single rubber material is also prone to aging under extreme temperature conditions, which affects the overall life and safety of the connector. In order to overcome these problems, steel wire braided rubber sheath connectors came into being. This connector combines the strength of steel wire with the elasticity and insulation of rubber to form a high-performance and high-reliability electrical connection solution.

[0003] For example, the patent document with the prior art announcement number CN212257940U discloses a steel wire braided rubber sheath connector, including a bracket hose, a compression shell arranged at both ends of the bracket hose, a joint arranged inside the compression shell, and a plug-in component arranged at the end of the joint, wherein a plug-in component is arranged inside the plug-in component, a sheathed communication cable is connected to the plug-in component, and the sheathed communication cable extends to the inside of the joint; a stopper is arranged inside the compression shell, and the cross section of the stopper is arranged in a stepped structure, and the front end diameter of the stopper is larger than the diameter of the rear end of the stopper; the front end of the compression shell is connected to the joint, and the rear end of the joint is pressed against the front side of the vertical part of the stopper, and the outer wall of the joint contacts the inner wall of the stopper, and the outer wall of the stopper contacts the inner wall of the compression shell; the outer diameter of the compression shell is larger than the outer wall of the plug-in component. The steel wire braided rubber sheath connector of the above structure is adopted in the patent document, which can realize nearly 360-degree rotation, and the protective sheath line used is anti-smashing, which prolongs the service life of the connector.

[0004] Although the existing steel wire braided rubber sheathed connectors with cables have demonstrated excellent performance in multiple industrial fields and significantly extended the service life of equipment with their flexible nearly 360-degree rotation design, the role played by precision sealing rings in ensuring the long-term stable operation of these connectors cannot be ignored. As a key interface component between the connector and the cable, the sealing ring is exquisitely designed and powerful. It not only provides a stable and reliable connection point between the connector and the cable through interference fit, but also forms a solid sealing barrier at the connection interface by using its highly elastic material properties. This barrier effectively blocks the intrusion of external harmful substances such as moisture, dust, and corrosive chemicals, protects the integrity of the internal structure of the connector, and also ensures the stable transmission of electrical signals. However, with the passage of time and changes in the working environment, the material of the sealing ring may gradually age and lose its original elasticity and sealing performance in a continuous high temperature, high pressure, humid or corrosive environment. In addition, since the connector may be subjected to mechanical stress from different directions during use, the sealing ring may also become a stress concentration area, resulting in local deformation or deflation. These changes will not only reduce the sealing effect of the sealing ring, but also may cause the connector and the cable to loosen or fall off, thus seriously affecting the normal operation of the device. To this end, the present application proposes a steel wire braided rubber sheath connector with a cable. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By setting up the inflation assembly and the sealing ring, the sealing ring can be automatically inflated during the connection process, thereby significantly improving the sealing effect between the connector and the cable or other equipment. The increased saturation of the sealing ring means tighter contact and less risk of leakage, which is particularly important for equipment working in harsh environments (such as humid, dusty or corrosive environments). The use of a one-way valve ensures the one-way flow of gas and prevents gas backflow, further ensuring the reliability and efficiency of the seal. The design of the trigger and the transmission slide bar enables the inflation action to be automatically triggered during the connection process without the need for additional operating steps, further simplifying the connection process. The two-layer steel wire braided hydraulic support hose provides strong physical protection for the cable, can resist external pressure, wear and impact, and extend the service life of the cable. The buckle sleeve cooperates with the buckle groove of the first mechanical connector to ensure the overall stability of the connector and reduce the risk of failure caused by loosening or falling off.

[0018] When the connector is hit by external forces or the sealing ring is under pressure, the gas in the sealing ring will be blown back to the air duct. Through the design of the one-way valve, the gas is guided into the reflux pipe, and the air pressure is automatically adjusted by the compensation piston rod. This process ensures that the connector can still maintain the stability of the internal air pressure when subjected to external forces, thereby maintaining the sealing of the sealing ring. When the air pressure changes, the compensation piston rod, seesaw, lifting plate and air-inflating piston rod and other components cooperate with each other to ensure that the amount of gas in the sealing ring is replenished in time, preventing sealing failure caused by insufficient air pressure. The lifting plate and the seesaw are connected by a sliding connection through a connecting roller, thereby realizing efficient transmission between the transmission slide rod and the air-inflating piston rod. This design enables each component to respond quickly when the air pressure changes, and jointly completes the compensation and adjustment of the air pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3 The present invention provides a technical solution: a steel wire braided rubber sheath connector with a cable, comprising a two-layer steel wire braided hydraulic support hose 102 and a first mechanical connector 100 connected to both ends thereof and a cable 200 placed inside the two-layer steel wire braided hydraulic support hose 102, wherein both ends of the cable 200 are respectively connected with core plugs 201 adapted thereto, the core plug 201 is used for the end of the cable to be connected with other equipment or cables, and one end of the two core plugs 201 is respectively fixedly connected with a plug connector 202, the plug connector 202 is used for quick connection between cables or between cables and equipment, and the outer surface of the cable 200 is provided with two second mechanical connectors 101 adapted to the first mechanical connector 100, and the second mechanical connector 101 is connected to the first mechanical connector 100 by a rotating limit pin.

[0035] See also Figure 3 , Figure 4 as well as Figure 5 The outer surface of the two-layer steel wire braided hydraulic support hose 102 is provided with a buckling sleeve 103, and the outer surface of the first mechanical connector 100 is provided with a buckle groove 104. One end of the buckle sleeve 103 is engaged in the buckle groove 104. The buckle groove 104 allows the buckle sleeve 103 to be stably connected to the first mechanical connector 100. The core plug 201 extends to the interior of the first mechanical connector 100 and is connected to the first mechanical connector 100 through a sealant. The outer surface of the first mechanical connector 100 is provided with a sealing groove 105. A sealing ring is placed in the sealing groove 105 for connecting the first mechanical connector 100 with the second mechanical connector 101. At the same time, the sealing ring placed in the sealing groove 105 can improve the stability of the connection between the second mechanical connector 101 and the first mechanical connector 100.

[0036] For further information, see Figure 6 , Figure 7 as well as Fig. 9The outer surface of the first mechanical connector 100 is sleeved with a sealing ring 300, which can be used when the first mechanical connector 100 is connected to the cable. The interior of the connector 202 is provided with an air passage 302 connected to the sealing ring 300, and the interior of the air passage 302 is provided with an inflatable component for pushing the gas flow inside it. The inflatable component includes a gas delivery piston rod 305 slidably connected to the interior of the air passage 302, and the piston end of the gas delivery piston rod 305 is adapted to the air passage 302. The outer surface of the gas delivery piston rod 305 is sleeved with a first spring 311 for its own reset, and the end of the gas delivery piston rod 305 away from its piston end is fixedly connected to a connecting inclined block 306. The connector 20 2 is slidably connected with a transmission slide bar 307, and the outer surface of the transmission slide bar 307 is provided with a power mechanism for driving the gas delivery piston rod 305 to move. The power mechanism includes a sleeve 309 fixedly connected to the outer surface of the transmission slide bar 307, and one end of the sleeve 309 is provided with a mounting block 312. The mounting block 312 is internally rotatably connected with a contact roller 310 slidably connected to the connecting inclined block 306. By providing an inflation component, the gas stored in the air passage 302 can be passed into the interior of the sealing ring 300, thereby improving the saturation of the sealing ring 300 and making it have a better sealing effect. The power mechanism can drive the gas delivery piston rod 305 to move, thereby delivering the gas to the sealing ring 300.

[0037] For further information, see Figure 8 , Fig.10 as well as Fig.11 A hollow groove is provided at the top of the connector 202, a slide groove 314 is provided in the hollow groove, a trigger member 313 is slidably connected inside the slide groove 314, the top of the transmission slide rod 307 extends to the inside of the hollow groove and is rotatably connected to a ball 308 adapted to the trigger member 313, a tension spring 315 fixedly connected to the trigger member 313 is fixedly connected in the hollow groove, the trigger member 313 can cooperate with the connector to move under force, and at the same time, the inclined surface at its bottom can effectively contact the ball 308 to drive the transmission slide rod 307 to move, and the tension spring 315 can pull the trigger member 313 to facilitate its subsequent reset.

[0038] Among them, the inner wall of the sealing ring 300 is fixedly connected with an air supply hose 301 that passes through the first mechanical connector 100 and is connected to the air duct 302. The inside of the air duct 302 is fixedly connected with a one-way valve 303. The inside of the air duct 302 is provided with a first balancing air hole 304. The one-way valve 303 allows the gas in the air duct 302 to pass through and be transported to the inside of the sealing ring 300, and the first balancing air hole 304 can maintain communication with the outside world and compensate for the gas in the air duct 302 at any time to ensure the smooth movement of the gas transmission piston rod 305.

[0039] It is worth mentioning that as the installation process proceeds, the trigger member 313 will be driven to move continuously, thereby driving the transmission slide rod 307 down. At this time, the inflation component will be started to continuously blow the gas in the air duct 302 into the interior of the sealing ring 300. These gases will first pass through the one-way valve 303, and the one-way valve 303 can prevent these gases from flowing back, thereby ensuring the efficiency of gas delivery.

[0040] Specifically, when the trigger member 313 is moved by the force during connection, it will contact the ball 308 and make it roll on the inclined surface at the bottom of the trigger member 313, thereby driving the transmission slide rod 307 to move downward and driving the sleeve 309 to move with it. At this time, the sleeve 309 will pull the contact roller 310 downward and slide on the inclined surface of the connecting inclined block 306, thereby driving the gas transmission piston rod 305 to slide in the air channel 302, thereby pushing the gas in the air channel 302. At this time, the gas in the air channel 302 is agitated by the gas transmission piston rod 305 and flows out through the one-way valve 303 and is transported to the inside of the sealing ring 300 through the gas supply hose 301, so that the gas inside the sealing ring 300 increases and the contact area between it and the components is increased.

[0041] In summary, by setting the inflation assembly and the sealing ring 300, the sealing ring can be automatically inflated during the connection process, thereby significantly improving the sealing effect between the connector and the cable or other equipment. The increased saturation of the sealing ring means tighter contact and less risk of leakage, which is particularly important for equipment working in harsh environments (such as humid, dusty or corrosive environments). The use of the one-way valve 303 ensures the one-way flow of gas and prevents gas backflow, further ensuring the reliability and efficiency of the seal. The design of the trigger 313 and the transmission slide bar 307 enables the inflation action to be automatically triggered during the connection process without the need for additional operating steps, further simplifying the connection process. The two-layer steel wire braided hydraulic support hose 102 provides strong physical protection for the cable, can resist external pressure, wear and impact, and extend the service life of the cable. The buckle sleeve 103 cooperates with the buckle groove 104 of the first mechanical connector 100 to ensure the overall stability of the connector and reduce the risk of failure caused by loosening or falling off.

[0042] Example 2: Please refer to Fig. 9 , Fig.10 as well as Fig.12The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a steel wire braided rubber sheath connector with a cable, a return pipe 400 connected to the air duct 302 is opened inside the connector 202, a compensation component is arranged inside the return pipe 400, the bottom of the transmission slide rod 307 extends to the inside of the return pipe 400, a cavity is opened inside the transmission slide rod 307, the bottom of the transmission slide rod 307 is slidably connected to the air replenishment piston rod 408, the piston end of the air replenishment piston rod 408 extends into the cavity of the transmission slide rod 307, and the bottom of the air replenishment piston rod 408 is fixedly connected to the lifting plate 406.

[0043] For further information, see Fig.11 , Fig.12 as well as Fig.13 The compensation component includes a compensation piston rod 402 slidably connected to the inside of the return pipe 400, the piston end of the compensation piston rod 402 is adapted to the inside of the return pipe 400, the compensation piston rod 402 can be used to bulge out the gas in the return pipe 400, and can flexibly adapt to the air pressure changes in the return pipe 400, the outer surface of the compensation piston rod 402 is sleeved with a second spring 403 for its own reset, one end of the compensation piston rod 402 is fixedly connected to a connecting piece 410, the inside of the return pipe 400 is rotatably connected to a seesaw 404, one end of the seesaw 404 is rotatably connected to a rotating bead 405 adapted to the connecting piece 410, the bottom of the lifting plate 406 is rotatably connected to a connecting roller 407 slidably connected to the seesaw 404, wherein the connecting roller 407 is slidably connected to the seesaw 404 so that the lifting plate 406 limits the position of the seesaw 404, so that when the lifting plate 406 moves down, the seesaw 404 is driven to flip, and when the lifting plate 406 moves up, the seesaw 404 is pulled to flip.

[0044] Among them, the inside of the casing 309 is slidably connected with a slide plate 409 fixedly connected to the mounting block 312, and one end of the slide plate 409 located in the casing 309 is fixedly connected with a gasket, which has sealing properties, so that when the gas in the transmission slide rod 307 increases, the gasket is pushed to move, and a second balancing air hole 401 is opened inside the return pipe 400, and the second balancing air hole 401 can connect the return pipe 400 with the outside to ensure balanced air pressure.

[0045] Specifically, when the first mechanical connector 100 is subjected to external collision or the sealing ring 300 is subjected to pressure, the gas in the sealing ring 300 will be blown back to the interior of the air passage 302. At this time, the one-way valve 303 blocks the gas reflux and allows the gas to enter the interior of the reflux pipe 400. As the gas in the reflux pipe 400 increases, the compensation piston rod 402 will be slightly pushed upward to be misaligned, so that the connecting piece 410 contacts the rotating ball 405, thereby driving the seesaw 404 to flip and driving the lifting plate 406 to move upward under force. At this time, the lifting plate 406 will drive the piston end of the gas replenishing piston rod 408 to slide inside the transmission slide rod 307, and drive the two slides 409 to be forced away from each other, thereby further pushing the gas transmission piston rod 305 downward, and blowing more gas in the air passage 302 into the interior of the sealing ring 300, thereby compensating for the gas discharged due to the force of the sealing ring 300.

[0046] It is worth mentioning that when the gas in the sealing ring 300 refluxes, it will flow into the air passage 302 and will be blocked by the one-way valve 303 and cannot pass through to enter the interior of the reflux pipe 400. At this time, the compensation piston rod 402 in the reflux pipe 400 will be reset by the agitation of the gas and drive the seesaw 404 to flip and push the gas-filling piston rod 408 to slide in the transmission slide bar 307 to compress the gas and drive the contact roller 310 to move. When the transmission slide bar 307 moves downward, it will drive the lifting plate 406 to move downward with it and drive the seesaw 404 to flip. At this time, the flipping of the seesaw 404 will also drive the compensation piston rod 402 to move and blow the gas in the reflux pipe 400 into the interior of the sealing ring 300. With the cooperation of the gas delivery piston rod 305 and the compensation piston rod 402, the gas in the reflux pipe 400 and the air passage 302 can be transported to the interior of the sealing ring 300.

[0047] In summary, when the connector is subjected to external collision or the sealing ring is subjected to pressure, the gas in the sealing ring 300 will be blown back to the air passage 302. Through the design of the one-way valve 303, the gas is guided into the return pipe 400, and the air pressure is automatically adjusted by the compensation piston rod 402. This process ensures that the connector can still maintain the stability of the internal air pressure when subjected to external force, thereby maintaining the sealing of the sealing ring. When the air pressure changes, the compensation piston rod 402, the seesaw 404, the lifting plate 406 and the air replenishing piston rod 408 cooperate with each other to ensure that the amount of gas in the sealing ring 300 is replenished in time, thereby preventing sealing failure caused by insufficient air pressure. The lifting plate 406 and the seesaw 404 are connected by a sliding connection through the connecting roller 407, thereby realizing efficient transmission between the transmission slide rod 307 and the air replenishing piston rod 408. This design enables each component to respond quickly when the air pressure changes, and jointly completes the compensation and adjustment of the air pressure.

[0048] Self-reset function: The second spring on the outer surface of the compensation piston rod makes it self-reset. After the air pressure stabilizes, the compensation piston rod can automatically reset to prepare for the next air pressure change.

[0049] Working principle: When in use, the cable is first connected to the inside of the first mechanical connector 100 to connect it to the connector 202. When the cable is connected to the inside of the connector 202, it will first contact the trigger 313 to make it move under force. At the same time, the inner conductor and the outer conductor of the cable are respectively connected to the corresponding parts of the first mechanical connector 100. Then, the sealing ring 300 and the fastener are closed to complete the connection.

[0050] When the trigger member 313 is moved by force during connection, it will contact the ball 308 to make it roll on the inclined surface at the bottom of the trigger member 313, thereby driving the transmission slide rod 307 to move downward and driving the sleeve 309 to move with it. At this time, the sleeve 309 will pull the contact roller 310 downward and slide on the inclined surface of the connecting inclined block 306, thereby driving the gas delivery piston rod 305 to slide in the air passage 302, thereby pushing the gas in the air passage 302. At this time, the gas in the air passage 302 is agitated by the gas delivery piston rod 305 and flows out through the one-way valve 303 and is transported to the inside of the sealing ring 300 through the gas supply hose 301, so that the gas inside the sealing ring 300 increases and the contact area between it and the components is increased;

[0051] When the first mechanical connector 100 is hit by an external collision or the sealing ring 300 is under pressure, the gas in the sealing ring 300 will be blown back to the inside of the air passage 302. At this time, the one-way valve 303 blocks the gas backflow and allows the gas to enter the inside of the reflux pipe 400. As the gas in the reflux pipe 400 increases, it will slightly push the compensation piston rod 402 to be dislocated upward, so that the connecting piece 410 contacts the rotating ball 405, thereby driving the seesaw 404 to flip and driving the lifting plate 406 to move upward under force. At this time, the lifting plate 406 will drive the piston end of the gas replenishing piston rod 408 to slide inside the transmission slide rod 307, and drive the two slides 409 to be forced away from each other, thereby further pushing the gas transmission piston rod 305 downward, and blowing more gas in the air passage 302 into the inside of the sealing ring 300, thereby compensating for the gas discharged due to the force of the sealing ring 300.
