Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a quick-installation new energy cable. Background Technology

[0002] With the rapid development of the new energy industry (such as new energy vehicles, photovoltaic power stations, wind power projects, energy storage systems, etc.), cables, as the core carrier of energy transmission, are facing increasingly complex application scenarios, and the requirements for assembly efficiency, adaptability, connection stability and protection performance are becoming increasingly stringent. In practical applications, the assembly process of traditional new energy cables on the market is cumbersome and inefficient: traditional cable splicing relies on welding and fixing, and multiple sets of bolts are tightened step by step. This not only requires professional technicians to operate, but also requires complex tools. The assembly process is time-consuming and cannot meet the rapid construction needs of new energy equipment installation, maintenance or emergency repair scenarios. Meanwhile, most existing cable connectors are specially designed. Single-strand cables and multi-strand cables require different specifications of adapter components. Moreover, once the adapter structure is fixed, the reuse rate is low. Furthermore, the connection between wires or between wires and equipment requires different connectors, making it impossible to use both simultaneously. In addition, new energy sources make greater use of electrical energy, so the cables are mostly thicker to prevent overheating and melting. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-installation new energy cable to solve the problems of low assembly efficiency, poor adaptability, unstable connection and insufficient protection of traditional new energy cables mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation new energy cable, comprising a first outer shell and a second outer shell, both the first and second outer shells being cylindrical structures with a connecting hole at the center of one end, and one end of the second outer shell being screwed into the first outer shell for docking, and both the first and second outer shells having detachable and installable identical wire-fixing structures; wherein the first and second outer shells serve as docking carriers and for protection, and the wire-fixing structures are used to fix the cable and for docking and connection.

[0005] Preferably, the wire fixing structure includes a wire fixing device, a pair of fixing bolts, a sleeve, a turntable, a contact post, and a spring; the wire fixing device is a tapered tube, and one end of the wire fixing device is provided with a hexagonal force-applying post. Both ends of the wire fixing device have oblique threads on their outer side walls, and the other end of the wire fixing device has equally spaced wire-passing openings. One end of the wire fixing device movably passes through a transition hole at one end of the first outer casing, and one end of the wire fixing device is screwed into the transition hole. The hexagonal force-applying post at one end of the wire fixing device is sealed at the transition hole. The pair of fixing bolts respectively movably pass through the hexagonal force-applying post of the wire fixing device. The sleeve is a hexagonal prism structure with threads on its inner sidewall. One end of the sleeve is detachably fitted onto the other end of the wire fastener, and the sleeve is screwed onto the other end of the wire fastener. The turntable is fixedly fitted onto the hexagonal prism at one end of the sleeve, and the turntable is equidistantly provided with several wire core holes. The contact post is an H-shaped cylindrical structure, and the middle part of the contact post moves through the middle of the other end of the sleeve. The spring is movably fitted onto one end of the contact post, and the spring is attached to the outer sidewall of the other end of the sleeve.

[0006] Preferably, a socket unit can be detachably installed on the first and second outer shells. The socket unit consists of an insulating shell and a collar. One end of the collar is fixedly inserted through the middle of the insulating shell, and the other end of the collar is a circular structure.

[0007] Preferably, the insulating outer shell is screwed into the first outer shell, and one end of the collar is in contact with and fitted to the contact post.

[0008] Preferably, when the first outer shell and the second outer shell are screwed together, the contact posts inside them are fitted together and compress the spring.

[0009] Preferably, when the wire fixing structure is connected to the multi-strand cable, the cable with insulation layer is clamped and fixed through the wire fixing device, and the multi-strand cores pass through the wire insertion port and the core hole of the turntable respectively, and are fixed by rotating the turntable.

[0010] Preferably, when the wire fixing structure is connected to a single-strand cable, after the cable passes through the wire fixing device, the internal wire core and the contact post are in contact with each other inside the sleeve.

[0011] Preferably, the sleeve, turntable, contact post, and collar are all conductive metal structures used for connection and transfer.

[0012] The present invention proposes a quick-installation new energy cable, which has the following advantages: This solution achieves detachable fixed structure and cable end through simple mechanical construction, improving reuse efficiency. At the same time, the convenient and quick disassembly and assembly method is beneficial to new energy production or maintenance. It also takes into account wire-to-wire and wire-to-equipment connections, and ensures the sealing and protection effect at the cable connection. Furthermore, it can switch the connection state according to the actual number of internal wire strands of the cable to ensure the stability of the connection and prevent loosening of the contact. 1. The cable fixing structure and the outer shell are detachable and assembled (the cable fixing device is screwed to the outer shell via a helical thread, the sleeve is screwed to the cable fixing device via a thread, and the fixing bolts are detachable). All core components (cable fixing device, sleeve, turntable, contact post, etc.) are designed to prevent one-time damage, and the integrity of the components is not affected during disassembly and assembly. There is no need to discard the entire connector due to cable replacement or docking adjustment. The core components can be repeatedly adapted to different cables or scenarios, which greatly reduces the waste of consumables and lowers the material costs for long-term use and maintenance.

[0013] 2. The simple mechanical transmission design with screw-on and bolt locking allows for quick docking between the first and second outer shells. The hexagonal force-applying post of the cable fastener facilitates tool unscrewing and disassembly. The threaded connection between the sleeve and the cable fastener eliminates the need for welding and other complex processes. No specialized or complex equipment is required throughout the entire process. During production and assembly, the combination of cable and connector can be completed quickly. During maintenance or emergency repairs, it can be efficiently disassembled and replaced, solving the pain points of traditional cable docking that are time-consuming and dependent on professional personnel, thus improving construction efficiency and maintenance convenience.

[0014] 3. Cable-to-cable connection: The first and second outer shells are screwed together, and the internal contact posts are in contact with each other for conductivity, enabling direct and rapid connection of two cables. Cable-to-equipment connection: Through a detachable socket unit (insulating shell and conductive collar), the insulating shell is screwed into the outer shell, one end of the collar is in contact with the contact post, and the other end can be connected to the equipment terminal, adapting to equipment interface requirements. No additional special connection accessories are required. The same connector can meet the needs of two core scenarios: cable-to-cable or cable-to-equipment, reducing the types of accessories required and improving the flexibility of scenario adaptation.

[0015] 4. Physical sealing: The hexagonal force-applying post of the cable tie seals the adapter hole, preventing external dust and rainwater from entering the connector; Protective barrier: The first and second outer shells are integral cylindrical structures, providing physical protection for the internal conductive components (contact posts, sleeves, etc.); Insulation protection: The insulating outer shell of the socket unit isolates the conductive components from the external environment, allowing human contact without the risk of leakage; It effectively prevents external impurities from corroding the conductive components, reduces the risk of short circuits and leakage in humid and dusty environments, and extends the service life of the cable connector, especially suitable for the protection needs of new energy outdoor equipment (photovoltaic, wind power) and vehicle-mounted scenarios.

[0016] 5. The same cable fixing structure can be adapted to single-strand or multi-strand wires through "modular design": Single-strand wires: The wire core is directly attached to the inner end of the contact post sleeve and fixed by the cable fixing device; Multi-strand wires: The wire core passes through the wire insertion port and the wire core hole of the turntable, and is clamped and positioned by the rotation of the turntable, without the need to replace the core components of the cable fixing structure; This avoids the limitations of traditional connectors that are dedicated to single-strand or multi-strand wires. During construction, there is no need to change the connector according to the wire core type, reducing the inventory of spare parts, improving construction flexibility, and reducing the risk of work delays caused by specification mismatch.

[0017] 6. Elastic clamping: When the outer shell is connected, the contact post is pressed against and compressed by the spring. The spring's rebound force continuously ensures that the contact post is tightly fitted, offsetting the gap caused by vibration; Multiple locking: The fixing bolt locks the cable holder to the outer shell, the turntable locks the multi-strand wire core, and the threaded connection (outer shell, cable holder, sleeve) itself has anti-loosening characteristics; Sufficient conductive contact: The contact post has an H-shaped structure with a large contact area with the wire core or collar, and the metal parts such as the sleeve and turntable have strong conductive continuity; Effectively avoids the problems of loose joints and poor contact caused by equipment vibration and environmental bumps, ensuring the stability and safety of energy transmission in new energy equipment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 The present invention provides a technical solution: a quick-installation new energy cable, including a first outer shell 1 and a second outer shell 2. Both the first outer shell 1 and the second outer shell 2 are cylindrical structures, and a transition hole 5 is opened in the middle of one end. One end of the second outer shell 2 can be screwed into the first outer shell 1 for docking. The same wire fixing structure 3 can be detachably installed in both the first outer shell 1 and the second outer shell 2. The first outer shell 1 and the second outer shell 2 are used as docking carriers and for protection, and the wire fixing structure 3 is used to fix the cable and for docking and connection.

[0022] As a preferred embodiment, the wire fixing structure 3 further includes a wire fixing device 31, a pair of fixing bolts 32, a sleeve 33, a turntable 34, a contact post 35, and a spring 36. The wire fixing device 31 is a tapered tube, and one end of the wire fixing device 31 is provided with a hexagonal force-applying post 7. Both ends of the wire fixing device 31 have oblique threads on their outer side walls, and the other end of the wire fixing device 31 has wire-passing ports 6 at equal intervals. One end of the wire fixing device 31 movably passes through the adapter hole 5 at one end of the first outer shell 1, and one end of the wire fixing device 31 is screwed into the adapter hole 5. The hexagonal force-applying post 7 at one end of the wire fixing device 31 is sealed in the adapter hole 5. The pair of fixing bolts 32 respectively movably pass through the hexagonal force-applying post 7 of the wire fixing device 31, and the fixing bolts 32 are screwed into the side wall of the first outer shell 1. One end of the sleeve 33 is a hexagonal prism structure, and the inner side wall in the middle is provided with threads. One end of the sleeve 33 can be detachably fitted onto... On the other end of the cable fastener 31, and the sleeve 33 is screwed to the other end of the cable fastener 31, the turntable 34 is fixedly fitted on the hexagonal prism at one end of the sleeve 33, and the turntable 34 is provided with a number of wire core holes 8 at equal intervals. The contact post 35 is an H-shaped cylindrical structure, and the middle part of the contact post 35 moves through the middle of the other end of the sleeve 33. The spring 36 is movably fitted on one end of the contact post 35 and is attached to the outer side wall of the other end of the sleeve 33. Through the structural design of the cable fastener 31, which is screwed to the sleeve 33, the cable fastener 31 can clamp and fix the cable passing through, and can also promote the stable contact between the wire core of the cable and the sleeve 33, the turntable 34 or the contact post 35, ensuring the stability of the contact post 35 docking. At the same time, the cable fastener 31 with the corresponding hole diameter is set so that it can directly fit after the cable passes through, ensuring the internal sealing protection after the first outer shell 1 and the second outer shell 2 dock.

[0023] More specifically, the cable fixing structure 3 is the core component for achieving cable fixing, conductive connection, and sealing protection. It adopts a modular and detachable design, with each component precisely fitted through threaded connections and assembly, providing multiple functions including fixing, conductivity, and sealing. The cable fixing device 31 is a tapered tube with a hexagonal force-applying post 7 at one end (for easy force application during assembly and disassembly). Both ends have oblique threads on their outer walls, and the other end has evenly spaced cable entry ports 6. One end of the device passes through the adapter hole 5 of the first outer shell 1 and is screwed in for fixation. The hexagonal force-applying post 7 seals the adapter hole 5 to ensure a tight seal. The matching aperture design allows for direct fitting when the cable passes through, enhancing the internal sealing protection after the outer shell is connected. This structure, through the screw-fitting of the cable retainer 31 and the sleeve 33, can reliably clamp and fix the passing cable, and promote stable contact between the cable core and the sleeve 33, the turntable 34, or the contact post 35, ensuring continuity of conductivity. At the same time, the sealing design and aperture adaptability of the cable retainer 31 achieve internal sealing protection after the outer shell is connected, and the elasticity of the spring 36 further enhances the stability of the contact post 35 connection.

[0024] As a preferred embodiment, the first housing 1 and the second housing 2 are further detachably equipped with a socket unit 4. The socket unit 4 consists of an insulating housing 41 and a collar 42. One end of the collar 42 is fixedly inserted through the middle of the insulating housing 41, and the other end of the collar 42 is a circular structure. By inserting the collar 42 through the middle of the insulating housing 41, the insulating housing 41 can effectively prevent electric shock and ensure that one end of the collar 42 is stably connected to the contact post 35.

[0025] More specifically, the socket unit 4 is a detachable auxiliary component adapted to cable splicing scenarios. Its core functions include insulation protection and stable conductivity. The socket unit 4 consists of an insulating shell 41 and a collar 42. Its structural design and functional adaptability are strong: the insulating shell 41 is the core protective component, which can be detachably installed on the first shell 1 or the second shell 2 and fixed by screwing. It can effectively isolate the internal conductive components from the external environment and play a safety protection role against electric shock. The collar 42 is a conductive metal structure (adapted to the overall conductivity requirements). One end is fixed through the middle of the insulating shell 41, and the other end is designed as a ring structure to ensure a tight fit with the contact post 35 of the fixed wire structure 3 and ensure the stability of the conductive connection. The insulating shell 41 provides the foundation for safety protection, and the collar 42 realizes the conductive connection.

[0026] As a preferred option, the insulating shell 41 is screwed into the first shell 1, and one end of the collar 42 is in contact with the contact post 35 to meet the cable connection requirements of the equipment.

[0027] As a preferred embodiment, when the first outer shell 1 and the second outer shell 2 are screwed together, the contact posts 35 inside them are fitted together and compress the spring 36 to contact the force of the spring 36, ensuring that the contact posts 35 are relatively stably connected.

[0028] As a preferred option, when the wire fixing structure 3 is connected to the multi-strand cable, the cable with insulation layer is clamped and fixed through the wire fixing device 31, and the multi-strand cores pass through the wire insertion port 6 and the core hole 8 of the turntable 34 respectively, and are fixed by rotating the turntable 34 for stable contact connection between the internal core and the sleeve 33.

[0029] As a preferred option, when the fixed structure 3 is connected to the single-strand cable, after the cable passes through the fixed device 31, the inner core and the contact post 35 are in contact with each other at one end inside the sleeve 33. When the single-strand cable is installed, and when the first outer shell 1 and the second outer shell 2 are connected, the contact post 35 extends and retracts to achieve stable connection between the contact posts 35 and stable contact between the contact post 35 and the cable.

[0030] As a preferred option, the sleeve 33, turntable 34, contact post 35, and collar 42 are all conductive metal structures used for transferring power.

[0031] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0032] S1. First, the device is installed in the first housing 1 and the second housing 2 respectively through the fixed wire structure 3. Then, the second housing 2 is rotated relative to the first housing 1 to realize the contact and connection of the internal fixed wire structure 3, so as to connect the cables and fix the cable connection end in the first housing 1 and the second housing 2 through the fixed wire structure 3. S2. When the cable core is multi-strand, as per the instruction manual... Figure 2 As shown, the wire fastener 31 is fixed by passing through the adapter hole 5 of the first outer shell 1 with the help of the hexagonal force-applying post 7 and screwing them together. Then, the cable is passed through the middle of the cable holder 31, with the cable diameter matching one end of the cable holder 31. The outer insulation layer of the cable is then removed from one end of the cable. After the multiple strands of wire are passed through the wire insertion port 6, the wires are separated and passed through the wire core holes 8 of the turntable 34. Then, the sleeve 33 is screwed onto the end of the cable holder 31 located inside the first housing 1. Through the conical design of the cable holder 31, the other end of the cable holder 31 is clamped and tightened during the screwing process of the sleeve 33. The rotation of the turntable 34 rotates the wire core, thereby achieving stable fixation. It will not fall off even when pulled. Finally, when the first outer shell 1 and the second outer shell 2 are screwed together, the internal contact posts 35 are relatively close together and can maintain a stable connection with the help of the spring 36. Then the wires are connected to each other through the wire core inside the cable and the metal structure of the turntable 34, sleeve 33 and contact post 35. S3. When the cable core is a single strand, after passing the cable through the cable holder 31, remove the insulation layer from one end of the cable and insert the inner core into the sleeve 33. As the sleeve 33 is screwed onto the cable holder 31 to clamp and fix the cable, the sleeve 33 will squeeze the core, making the core fully contact the sleeve 33 and the contact post 35. When the contact posts 35 are fitted together, as the first outer shell 1 and the second outer shell 2 are screwed together, the contact posts 35 will be compressed, so that the contact posts 35 are subjected to force and further fully contact and communicate with the core.

[0033] S4. When the cable is connected to the equipment, one end of the cable can be connected through the first housing 1 and the cable fastener 31. Then, the insulating housing 41 in the sleeve unit 4 is screwed to the first housing 1. One end of the middle collar 42 is attached to the contact post 35 to achieve contact and communication between the fixed cable and the collar 42. Thus, the equipment can be easily and stably connected by bolts or the like through the collar 42 at one end of the ring.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
