Description

Technical Field

[0001] This utility model specifically relates to the field of cable protection technology, and more specifically to a protective cable with a reinforcing member at the connector. Background Technology

[0002] In fields such as industrial control, communication transmission, and rail transportation, cables serve as the core carriers of energy and signal transmission, and the reliability of their connectors directly determines the stability of system operation. However, traditional cable connectors generally suffer from three major problems: First, the protective structure is weak. Most connectors rely solely on simple sleeve wrapping, lacking layered protective designs such as the introduction of rubber sleeves and sealing rings, making them susceptible to dust and moisture intrusion, leading to oxidation of the internal conductor bundle and poor contact at the connector's internal contacts. Second, their resistance to external forces is insufficient. There are no elastic buffer structures such as reinforcing connectors at the connection between the connector and the cable. When the cable is stretched or vibrated, the conductor connection assembly is prone to detaching from the internal contacts of the connector, and even the cable body and the connector body may break. Third, their assembly and fixation are poor. Traditional conductor fixation mostly relies on wrapping with tape, without precise positioning of conductor fixing components. The conductor bundle is prone to displacement, leading to conductive failures. Furthermore, the connection between the connector and the cable lacks elastic retaining rings and snap-fit ​​structures with connecting grooves, making it easy to loosen after installation.

[0003] These problems increase the failure rate of traditional cable connectors, especially in humid and vibrating industrial environments, where their average service life is significantly reduced, requiring frequent replacement and maintenance. This not only increases enterprise costs but may also lead to safety hazards such as production interruptions and equipment damage due to sudden failures. Utility Model Content

[0021] Please see Figure 1-7 In this embodiment of the invention, a protective cable with a reinforcing member at the connector includes... The cable body 1 has a reinforcing connector 2 installed on the outer front end of the cable body 1; the front ends of the cable body 1 and the reinforcing connector 2 are connected to the connector body 3. The reinforcing connector 2 includes a connecting protective sleeve 21. The inner sides of the upper and lower ends of the connecting protective sleeve 21 are symmetrically provided with movable grooves 23. The front ends of the movable grooves 23 are symmetrically provided with springs 24. The other end of the springs 24 is fixedly connected to the movable base 25.

The left and right sides of the slide plate 26 are slidably connected to the sliding grooves 27. The sliding grooves 27 are symmetrically arranged on the left and right sides and are respectively located on the inner sides of the upper and lower ends of the connecting protective sleeve 21.

[0022] By adopting the above technical solution, the spring 24 not only tightens the reinforcing sleeve 28 and the connector housing 31 with the compression reaction force after connection to prevent the elastic retaining ring 29 from loosening, but also absorbs external force through its own elastic deformation when the equipment vibrates or the cable is slightly stretched, avoiding stress transmission to the wire connection assembly 15 and the inner contact 32 of the connector, reducing contact point wear and improving the stability of the conductive connection.

[0023] In this embodiment, the movable base 25 and the slide plate 26 are symmetrically arranged at the upper and lower ends of the protective sleeve 21, and the outer side of the symmetrically arranged slide plate 26 is fixedly connected to the reinforcing sleeve 28. The inner side of the front end of the reinforcing sleeve 28 is provided with an elastic retaining ring 29, and the inner side of the elastic retaining ring 29 is provided with a sealing ring 210. The elastic retaining ring 29 and sealing ring 210 on the inner side of the front end of the reinforcing sleeve 28 are connected to the rear end of the connector housing 31. The inner side of the connector housing 31 is provided with the connector inner contact 32, and the front end of the connector housing 31 is provided with the connector outer insertion end 33.

[0024] By adopting the above technical solution, the elastic retaining ring 29 on the inner side of the reinforcing sleeve 28 adopts a snap-fit ​​and press-release design. Pushing the reinforcing sleeve 28 can complete the quick connection, and pressing the protruding end of the elastic retaining ring 29 can achieve quick disassembly, thus realizing efficient and fast assembly and disassembly.

[0025] In this embodiment, the inner contact 32 of the connector is connected to the front end of the wire docking assembly 15, and the rear end of the wire docking assembly 15 is connected to the cable; the wire docking assembly 15 is installed inside the wire fixing member 14. The wire fixing member 14 is installed inside the docking protective sleeve 16, and the rear end of the wire fixing member 14 is connected to the front end of the wire bundle 13. The outer side of the front end of the wire bundle 13 is connected to the inner side of the rear end of the docking protective sleeve 16, and the outer side of the rear end of the docking protective sleeve 16 is connected to the transition connector 12.

[0026] By adopting the above technical solution, the wire fixing component 14 radially positions the wire bundle 13 and the wire docking assembly 15, which can prevent the wire bundle 13 from shifting under vibration environment, ensure that the wire docking assembly 15 and the inner contact 32 of the connector always maintain surface contact, and ensure accurate and stable internal conductive connection.

[0027] In this embodiment, the rear end of the transition connector 12 is connected to the inner side of the front end of the inlet sleeve 11; the front end of the docking protective sleeve 16 is provided with symmetrical elastic buckles, and the symmetrically arranged elastic buckles are connected to the connecting groove 22 provided at the front end of the connecting protective sleeve 21, and the inner side of the connecting protective sleeve 21 is connected to the docking protective sleeve 16.

[0028] By adopting the above technical solution, the rubber sleeve 11 is introduced to cooperate with the transition connector 12, which not only prevents external impurities from entering the cable body 1, but also buffers the bending stress of the cable through the elastic deformation of the rubber sleeve, avoiding the outer insulation layer of the cable from cracking due to frequent bending, and extending the service life of the cable body 1. The sealing ring 210 inside the reinforcing sleeve 28 achieves joint end sealing, the snap connection between the mating protective sleeve 16 and the connecting protective sleeve 21 achieves quick installation in the middle, and the introduction of the rubber sleeve 11 achieves cable entry sealing. It can adapt to humid, dusty, and oily industrial environments, reduce the risk of joint failure caused by corrosion, and improve compatibility.

[0029] The working principle of this utility model is as follows: the front end of the cable body 1 passes through the inlet sleeve 11, and the outer protective connection is completed through the transition connector 12. One end of the wire docking assembly 15 is crimped and fixed with the wire bundle 13, and the other end extends into the interior of the connector body 3, and is precisely docked with the contact point 32 inside the connector to form a conductive path. At this time, the spring 24 is in a naturally extended state. Under the natural elastic force of the spring 24, the movable base 25 is pushed backward and completely fits against the inner side of the rear end of the movable groove 23. Since the reinforcing sleeve 28 is fixedly connected to the movable base 25 through the sliding plate 26, the reinforcing sleeve 28 is in the rear end position synchronously with the movable base 25, maintaining a safe distance from the connector housing 31. This provides operating space for the early alignment of the cable body 1 and the connector body 3, and for the precise contact between the wire docking assembly 15 and the inner contact point 32 of the connector, thus avoiding the reinforcing sleeve 28 from obstructing and affecting the assembly. After the cable body 1 and the connector body 3 complete the internal wire connection, the operator pushes the reinforcing sleeve 28 forward. The reinforcing sleeve 28 drives the sliding plate 26 to slide forward along the sliding groove 27. The sliding plate 26 simultaneously transmits the thrust to the moving base 25, causing the moving base 25 to move forward along the movable groove 23, squeezing the spring 24 from its natural state to its compressed state. As the pushing action continues, the front end of the reinforcing sleeve 28 gradually approaches the rear end of the connector housing 31 until the elastic retaining ring 29 on the inner side of the front end of the reinforcing sleeve 28 aligns with the annular retaining groove at the rear end of the connector housing 31. The elastic retaining ring 29 automatically springs into the retaining groove, realizing the quick engagement connection between the reinforcing sleeve 28 and the connector housing 31. At this time, the pushing force is released, and the compressed spring 24 generates a backward reaction force, which is transmitted to the reinforcing sleeve 28 through the moving base 25 and the sliding plate 26, so that the reinforcing sleeve 28 always fits tightly against the connector housing 31. This not only prevents the elastic retaining ring 29 from loosening due to vibration, but also absorbs external vibration through the deformation of the spring 24 in subsequent use, preventing vibration from being transmitted to the internal wire connection point and ensuring a stable conductive connection. The rubber sleeve 11 is introduced to cooperate with the transition connector 12, which not only prevents external impurities from entering the cable body 1, but also buffers the bending stress of the cable through the elastic deformation of the rubber sleeve, avoiding the outer insulation layer of the cable from cracking due to frequent bending, and extending the service life of the cable body 1. The wire fixing component 14 provides radial positioning for the wire bundle 13 and the wire docking assembly 15, which can prevent the wire bundle 13 from shifting under vibration and ensure that the wire docking assembly 15 and the inner contact 32 of the connector always maintain surface contact, thus ensuring accurate and stable internal conductive connection. The elastic retaining ring 29 on the inner side of the reinforcing sleeve 28 adopts a snap-fit ​​and press-release design. Pushing the reinforcing sleeve 28 can complete the quick connection, and pressing the protruding end of the elastic retaining ring 29 can achieve quick disassembly, realizing efficient and fast assembly and disassembly. The spring 24 not only tightens the reinforcing sleeve 28 and the connector housing 31 with the compression reaction force after connection to prevent the elastic retaining ring 29 from loosening, but also absorbs external force through its own elastic deformation when the equipment vibrates or the cable is slightly stretched, avoiding stress transmission to the wire docking assembly 15 and the inner contact 32 of the connector, reducing contact point wear and improving the stability of the conductive connection. The sealing ring 210 inside the reinforcing sleeve 28 achieves joint end sealing, the snap connection between the mating protective sleeve 16 and the connecting protective sleeve 21 achieves quick installation in the middle, and the introduction of the rubber sleeve 11 achieves cable entry sealing. It can adapt to humid, dusty, and oily industrial environments, reduce the risk of joint failure caused by corrosion, and improve compatibility.
