Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an energy storage cable. Background Technology

[0002] Energy storage cables, as the core carrier of energy transmission in energy storage systems, directly impact the operational safety of the entire system due to their connection reliability. These cables typically use multi-strand soft copper conductors to enhance flexibility, and are wrapped with a specially formulated rubber or thermoplastic elastomer insulation layer, possessing characteristics such as resistance to high and low temperatures and UV aging. Generally, the connection between two cable sections is reinforced with tape. As a key transmission component in new energy power systems, energy storage cables construct energy transmission networks between energy storage containers, battery packs, converters, and inverters, undertaking the storage and distribution functions of renewable energy sources such as solar and wind power. These cables are mainly used on the DC side of battery energy storage systems, responsible for power transmission between the battery pack and the combiner box; their performance directly affects the stability and efficiency of the entire energy storage system.

[0003] Traditional cables not only need to operate in complex environments, but also need to support reliable connections between the main cable and multiple branch cables. Currently used connection methods suffer from drawbacks such as simple structure and poor sealing, leading to easy breakage and corrosion at the connection points, seriously affecting the safe operation of the system. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide an energy storage cable to solve the problem of weak connection of traditional energy storage cables mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An energy storage cable includes a first cable, a second cable fixedly disposed at the right end of the first cable, and a connecting mechanism sleeved on the outer ring of the first and second cables. The connecting mechanism includes a sleeve, and an anti-slip sleeve is sleeved on the outer ring of the first and second cables. The sleeve acts as an external protective shell to enclose the entire connecting mechanism, providing mechanical protection and maintaining structural integrity. The anti-slip sleeve adopts a textured design to increase the friction coefficient of the palm contact surface during operation.

[0009] As a further improvement to the above solution, connecting rods are fixedly provided at both ends of the sleeve, and collars are fixedly provided at both ends of the connecting rods. The connecting rods, as the core load-bearing components, transmit rotational torque and maintain axial stability, while the collars provide a circular track for the rotating components to ensure accurate motion trajectory.

[0010] As a further improvement to the above solution, nuts are rotatably provided at both ends of the collar, and a limiting end is fixedly provided at the end of the nut near the collar. The nut converts the rotational motion into axial thrust through the engagement of the internal and external threads. The limiting end is provided with a flange structure to prevent excessive displacement of the nut from causing the mechanism to fail.

[0011] As a further improvement to the above solution, a locking sleeve is fixedly installed inside the sleeve. The locking sleeve is a hollow cone shape, and several contraction slits are opened on the outer ring of the locking sleeve. The locking sleeve adopts a cone-shaped segmented design to generate radial contraction deformation under axial pressure. The contraction slits enable the locking sleeve to have elastic deformation capability to adapt to different cable diameters.

[0012] As a further improvement to the above solution, the inside of the lock sleeve is fixedly provided with anti-slip texture, and the outer ring of the lock sleeve is fixedly provided with external thread. The anti-slip texture enhances the interlocking force between the inner wall of the lock sleeve and the cable sheath through the cross groove texture, and the external thread converts the rotational kinetic energy of the nut into the mechanical energy of the lock sleeve contraction.

[0013] As a further improvement to the above solution, the sleeve and connecting rod are provided with through holes for accommodating the first cable and the second cable. A rubber ring is fixedly installed on the outer layer of the through hole. The through hole serves as a cable passage and restricts the radial swing amplitude of the cable. The rubber ring uses elastic deformation to fill the microscopic gap between the cable and the through hole to form a waterproof barrier.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This energy storage cable uses a mechanical locking structure to reinforce the cable connection. By rotating the nut, the locking sleeve contracts, closing the contraction joint and pressing the cable surface. The anti-slip texture greatly increases the contact friction. Compared with the traditional tape wrapping method, its tensile strength and stability are significantly improved, effectively preventing the cable joint from loosening and falling off due to vibration or external force.

[0016] 2. The energy storage cable has a rubber ring inside the tube to form a sealing barrier, preventing moisture and dust from entering the cable connection. The anti-slip sleeve enhances the grip comfort during operation. The collar and the limiting end cooperate to ensure that the nut will not come off when rotating. The overall structure can maintain long-term reliability even in harsh environments.

[0017] 3. This energy storage cable optimizes the on-site installation process. It only requires inserting the cable and rotating the nut to complete the fixation. No special tools or complicated operations are required. The conical design of the locking sleeve adapts to cables of different diameters, making it highly versatile and significantly reducing construction time and labor costs. It is especially suitable for energy storage system scenarios that require frequent wiring. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] An energy storage cable includes a first cable 1, a second cable 2 fixedly disposed at the right end of the first cable 1, and a connecting mechanism 3 sleeved on the outer ring of the first cable 1 and the second cable 2. The connecting mechanism 3 includes a sleeve 301, and an anti-slip sleeve 302 is sleeved on the sleeve 301. The first cable 1 serves as the main conductor to transmit electrical energy, and the second cable 2 is connected to the first cable 1 to form a complete circuit. The connecting mechanism 3 includes a sleeve 301 to provide a mechanical protective shell and fix internal components, and an anti-slip sleeve 302 to increase friction during hand operation to prevent slippage.

[0027] Connecting rods 303 are fixedly installed at both ends of the sleeve 301. Collars 304 are fixedly installed at both ends of the connecting rods 303. Nuts 305 are rotatably installed at both ends of the collars 304. A limiting end 306 is fixedly installed at the end of the nut 305 near the collar 304. The connecting rods 303 support the overall structure and transmit rotational force. The collars 304 serve as the rotation base of the nut 305. The nut 305 generates axial locking force through threaded rotation. The limiting end 306 restricts the axial displacement range of the nut 305.

[0028] A locking sleeve 307 is fixedly installed inside the sleeve 301. The locking sleeve 307 is a hollow cone shape. Several contraction grooves 308 are opened on the outer ring of the locking sleeve 307. An internal thread 309 is fixedly installed inside the locking sleeve 307. An external thread 310 is fixedly installed on the outer ring of the locking sleeve 307. Through holes 311 for accommodating the first cable 1 and the second cable 2 are opened inside the sleeve 301 and the connecting rod 303. A rubber ring 312 is fixedly installed on the outer layer of the through hole 311. The locking sleeve 307 radially clamps the cable by contraction deformation. The contraction grooves 308 enable the locking sleeve 307 to have elastic contraction capability. The anti-slip texture 309 increases the friction coefficient between the locking sleeve 307 and the cable surface to prevent slippage. The external thread 310 converts the rotational movement of the nut 305 into the contraction action of the locking sleeve 307. The through hole 311 provides a cable passage and restricts displacement. The rubber ring 312 achieves a waterproof seal between the through hole 311 and the cable.

[0029] Working principle: First, the first cable 1 is inserted through the nut 305 and through the connecting mechanism 3 through the through hole 311, so that the right end of the first cable 1 is connected to the second cable 2. After the cable connection is completed, the connection is pulled back into the sleeve 301. The operator holds the anti-slip sleeve 302 and uses a tool to rotate the nut 305. The nut 305 drives the locking sleeve 307 to rotate through the external thread 310. During the rotation, the contraction joint 308 is compressed and closed, causing the locking sleeve 307 to contract radially. At the same time, the anti-slip texture 309 inside the locking sleeve 307 generates friction and locks with the surfaces of the first cable 1 and the second cable 2. The connecting rod 303 maintains structural stability through the collar 304. The limiting end 306 prevents the nut 305 from coming out of the collar 304. The rubber ring 312 forms a sealing barrier at the through hole 311. This process is carried out simultaneously at both ends of the sleeve 301, thereby realizing the mechanical fixing and waterproof protection of the two cables.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
