Description

Technical Field

[0001] The present invention relates to the technical field of cables, and more specifically, to an impact-resistant buffer-type low-voltage cable. Background Art

[0002] A cable is a wire product used to transmit electrical (magnetic) energy, information, and realize the conversion of electrical and magnetic energy. It can be defined as an aggregate composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, total protective layer, and outer protective layer. A cable may also have additional non-insulated conductors. Cables can be divided into high-voltage cables and low-voltage cables according to voltage, and low-voltage cables are extremely vulnerable to external interference during use.

[0003] Currently, low-voltage cables on the market only rely on the armor layer and insulation layer of the cable itself for protection, lacking a dedicated protection structure. Their anti-external interference performance is poor. When subjected to external interference such as impact, pulling, and shearing, they are prone to damage or even breakage. Moreover, the joints of the cable are also prone to looseness, detachment, or even breakage due to external impact, affecting the normal use of the cable, and prone to electric shock accidents or even fires. Therefore, we propose an impact-resistant buffer-type low-voltage cable, which can provide better protection for the cable itself and the joints, and reduce the interference of external forces on the cable power supply. Summary of the Invention

[0004] The present invention proposes an impact-resistant buffer-type low-voltage cable, which solves the problem in the prior art that external forces are likely to cause cable damage and interfere with the cable power supply.

[0014] Socket, which is fixedly connected inside the connector. There are multiple sockets, and the sockets correspond to the wire cores one by one. The sockets and the wire cores are electrically connected, and the plugs and the sockets are in plug-in fit;

[0015] Limiting component, which is used to limit the connected components. The limiting component includes:

[0016] Limiting seat, which is fixedly connected to the outside of the connector. A limiting opening is provided on the limiting seat;

[0017] Limiting block, which is fixedly connected to one end of the connection socket close to the connector through an elastic plate. The limiting block is wedge-shaped, and one end of the limiting block close to the connection socket contacts the limiting seat.

[0018] To release the limit of the limiting component on the connected components, a disassembly component is further included. The disassembly component is used to release the limit of the limiting seat on the limiting block. The disassembly component includes:

[0019] Sliding seat, which is fixedly connected to the connector;

[0020] Pressing plate, which is slidably connected to the sliding seat through a sliding rod. The pressing plate contacts the limiting block, and a return spring is provided between the pressing plate and the sliding seat;

[0021] Pulling rope, a rope loop is fixedly connected to one end of the pressing plate away from the limiting block, and the pulling rope passes through multiple rope loops;

[0022] Twisting block, which is fixedly connected to the pulling rope.

[0023] To further protect the cable, an auxiliary protection component is further included. The auxiliary protection component includes:

[0024] Connection block, two connection blocks are fixedly connected to the protection plate;

[0025] Spring tube, the two ends of the spring tube are respectively detachably connected to the connection blocks on two adjacent protection plates.

[0026] To further reduce the collision on the cable, a plurality of balls are rotatably connected to the connection block, and an installation component is arranged outside the outer sheath. The installation component is used to limit the cable unit, and the installation component includes:

[0027] An installation ring, which is installed outside one of a plurality of groups of protection plates through a plurality of installation springs;

[0028] Vacuum suction cups, a plurality of vacuum suction cups are provided, and the vacuum suction cups are fixedly connected to the outside of the installation ring at equal angles.

[0029] To further protect the cable unit, a plurality of spring-shaped metal wires are wound inside the outer sheath, and the spring-shaped metal wires and the protection component are arranged alternately.

[0030] The working principle and beneficial effects of the present invention are as follows:

[0031] 1. In the present invention, the outside of the cable unit is protected against impact by the protection plate. At the same time, the impact force is buffered by the buffer block and the buffer spring. The impact force is absorbed by the telescopic movement of the telescopic rod and the deformation of the buffer block, reducing the transmission of the impact force to the inside of the cable unit and causing damage to the wire core. At the same time, the cable unit between two adjacent groups of protection plates is protected by the spring-shaped metal wire, reducing the puncture and impact damage of foreign objects to the outer sheath. At the same time, the outside of the protection plate and the spring-shaped metal wire is protected by the spring tube, further improving the protection of the cable unit.

[0032] 2. In the present invention, the plug and the socket are inserted and electrically connected to two cable units through the sliding cooperation of the connection head and the connection seat. During the connection process of the connection head and the connection seat, the limiting block is inserted into the limiting port of the limiting seat. When the limiting block is inserted into the limiting port, the elastic plate is bent. After the limiting block passes through the limiting port, the elastic plate rebounds to its original position, and the limiting block contacts the limiting seat, limiting the connection head and the connection seat, ensuring the stability of the connection between the plug and the socket.

[0033] 3. In the present invention, when the cable unit needs to be disassembled, the torsion block is rotated to wind the pull rope. The pull rope is tightened to press the pressing plate. The pressing plate presses the limiting block, so that the limiting block enters the inside of the limiting port, and the connection head and the connection seat can be separated. The torsion block is released, and under the action of the reset spring, the pressing plate moves away from the sliding seat, avoiding hindering the limiting block.

[0034] 4. In the present invention, when laying the cable, the vacuum suction cup adsorbs on the ground or wall surface, and the installation ring protects the outside of the cable unit. When subjected to external impact, the cable unit can move inside the installation ring, and the cable unit moves by the rotation of the ball. Compared with the cable unit directly bearing the external force in a fixed state, the present invention avoids the impact force to a certain extent by the movement of the cable unit, reducing cable damage.

[0035] 4. Therefore, compared with the low-voltage cables in the prior art, the present invention protects the outside of the outer sheath through the protection plate and the spring-shaped metal wire, and at the same time, the spring tube protects the outside of the protection plate and the spring-shaped metal wire. The installation ring is fixed at the installation position through the vacuum suction cup to control the direction of the cable unit. Further protection is provided to the outside of the protection plate through the installation ring and the installation spring. At the same time, when subjected to external impact, the cable unit can move within a certain range through the rotation of the ball and the elasticity of the installation spring, reducing the direct resistance to the external force, thereby protecting the cable unit. Through the cooperation of the limit block and the limit seat, the stability of the connection between the connector and the connection seat as well as the plug and the socket is ensured, avoiding the disconnection of the electrical connection of the cable unit when being impacted. The pull rope is wound by the twisting block, so that the pull rope presses the pressing plate, and the limit block is pressed into the inside of the limit port, and the connection seat and the connector can be separated, disassembling the cable unit.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0056] Such as Figures 1 to 9As shown in the figure, this embodiment proposes a shock-proof buffer-type low-voltage cable, which includes a cable unit. The cable unit includes a conductor core 101, an armor layer 102, and an outer sheath 103. An insulating layer surrounds the outside of the conductor core 101. There are multiple conductor cores 101. The armor layer 102 is located outside the multiple insulating layers. There is a filling between the armor layer 102 and the insulating layer. The outer sheath 103 surrounds the outside of the armor layer 102. The armor layer 102 and the outer sheath 103 can provide a certain degree of protection for the conductor core 101. It also includes a protection component, a connection component, and a limiting component. Compared with the low-voltage cables in the prior art, in this invention, the outside of the outer sheath 103 is protected by a protection plate 201 and a spring-shaped metal wire 2. At the same time, a spring tube 602 protects the outside of the protection plate 201 and the spring-shaped metal wire 2. The mounting ring 701 is fixed at the mounting position through a vacuum suction cup 702 to control the direction of the cable unit. Further protection is provided for the outside of the protection plate 201 through the mounting ring 701 and a mounting spring 703. At the same time, when being externally impacted, the cable unit can move within a certain range through the rotation of the ball 1 and the elasticity of the mounting spring 703, reducing the direct resistance to the external force, thereby protecting the cable unit. Through the cooperation of the limiting block 402 and the limiting seat 401, the stability of the connection between the connector 301 and the connection socket 302, as well as the plug 303 and the socket 304, is ensured, avoiding the disconnection of the electrical connection of the cable unit when being impacted. By twisting the twisting block 504 to wind up the pull rope 503, the pull rope 503 presses the pressing plate 502, pressing the limiting block 402 into the inside of the limiting port, and the connection socket 302 and the connector 301 can be separated to disassemble the cable unit.

[0057] The protection component is arranged outside the outer sheath 103. The protection component includes a protection plate 201 and a buffer block 202. The protection plate 201 is arranged outside the outer sheath 103 through a plurality of buffer springs 203 and a plurality of telescopic rods 204. There are multiple groups of protection plates 201, and each group has multiple protection plates 201. The multiple protection plates 201 in a single group are arranged at equal angles outside the outer sheath 103. The buffer block 202 is fixedly connected inside the outer sheath 103. One end of the buffer block 202 contacts the protection plate 201 close to the outer sheath 103. The multiple protection plates 201 surround the outer sheath 103. The outside of the cable unit is protected by the protection plate 201. At the same time, the impact received by the protection plate 201 is buffered by the buffer spring 203 and the buffer block 202. The telescopic rod 204 has a certain sliding damping, and the impact force is absorbed through the sliding of the telescopic rod 204, so as to reduce the impact force entering the cable unit and protect the cable unit. To further protect the cable unit, a plurality of spring-shaped metal wires 2 are wound inside the outer sheath 103. The spring-shaped metal wires 2 and the protection component are arranged alternately. The gaps between two adjacent groups of protection plates 201 are protected by the spring-shaped metal wires 2 to prevent the cable unit from being punctured, and the cable unit is protected more comprehensively.

[0058] The connecting component is used to connect two cable units. The connecting component includes a connector 301, a connection seat 302, a plug 303 and a socket 304. The connector 301 is fixedly connected to one end of the cable unit. The connection seat 302 is fixedly connected to the other end of the cable unit. The connector 301 and the connection seat 302 are in sliding fit. The plug 303 is fixedly connected inside the connection seat 302. There are multiple plugs 303, and the plugs 303 correspond to the wire cores 101 one by one. The plugs 303 are electrically connected to the wire cores 101. The socket 304 is fixedly connected inside the connector 301. There are multiple sockets 304, and the sockets 304 correspond to the wire cores 101 one by one. The sockets 304 are electrically connected to the wire cores 101. The connector 301 and the connection seat 302 are connected. The plug 303 can be inserted into the socket 304. The plug 303 and the socket 304 are made of metal, and the wire cores 101 in two sections of cable units can be electrically connected.

[0059] The limiting component is used to limit the connected connecting components. The limiting component includes a limiting seat 401 and a limiting block 402. The limiting seat 401 is fixedly connected to the outside of the connecting head 301. A limiting opening is provided on the limiting seat 401. The limiting block 402 is fixedly connected to one end of the connecting seat 302 close to the connecting head 301 through an elastic plate 403. The limiting block 402 is wedge-shaped. One end of the limiting block 402 close to the connecting seat 302 contacts the limiting seat 401. During the connection process of the connecting head 301 and the connecting seat 302, the limiting block 402 approaches the limiting seat 401, and the tip of the limiting block 402 inserts into the inside of the limiting opening. As the limiting block 402 moves, the side with a larger thickness of the limiting block 402 gradually enters the limiting opening. When the limiting opening presses the limiting block 402, the elastic plate 403 is bent. When the connecting head 301 and the connecting head 301 are tightly attached and completely connected, the limiting block 402 passes through the limiting opening, and under the action of the elastic plate 403, the limiting block 402 rebounds. The end with a larger thickness of the limiting block 402 contacts the limiting seat 401 to limit the connecting head 301 and the connecting seat 302, preventing them from separating when subjected to external impacts, thereby ensuring the stability of the connection between the two cable units.

[0060] To release the limitation of the limiting component on the connecting components, a disassembly component is further included. The disassembly component is used to release the limitation of the limiting seat 401 on the limiting block 402. The disassembly component includes a sliding seat 501, a pressing plate 502, a pulling rope 503, and a twisting block 504. The sliding seat 501 is fixedly connected to the connecting head 301. The pressing plate 502 is slidably connected to the sliding seat 501 through a sliding rod 505. The pressing plate 502 contacts the limiting block 402. A return spring 506 is provided between the pressing plate 502 and the sliding seat 501. One end of the pressing plate 502 away from the limiting block 402 is fixedly connected with a rope loop 507. The pulling rope 503 passes through a plurality of rope loops 507. The twisting block 504 is fixedly connected to the pulling rope 503. Initially, under the action of the return spring 506, the pressing plate 502 is away from the sliding seat 501, and the pressing plate 502 is away from the limiting block 402. When it is necessary to disconnect the connection of the two cable units, the twisting block 504 is rotated to wind and reel in the pulling rope 503, reducing the total length of the pulling rope 503. The rope loops 507 formed by the pulling rope 503 contract, applying a force towards the center to the pressing plate 502, that is, pressing the pressing plate 502, so that the pressing plate 502 presses the limiting block 402. The limiting block 402 is pressed into the corresponding position of the limiting opening. By pulling the connecting head 301 and the connecting seat 302, the limiting block 402 can be pulled out from the inside of the limiting opening, separating the plug 303 and the socket 304, thereby adjusting the total length of the low-voltage cable and replacing the damaged cable unit in time. Compared with the method of replacing the entire cable when a certain part of the cable is damaged, through the connection method of multiple cable units, the replacement cost can be reduced.

[0061] To further protect the cable, an auxiliary protection component is also included. The auxiliary protection component includes a connecting block 601 and a spring tube 602. Two connecting blocks 601 are fixedly connected to the protection plate 201. A connecting port is provided on the connecting block 601. The two ends of the spring tube 602 are respectively detachably connected to the connecting blocks 601 on two adjacent protection plates 201. Spring buckles are connected to both ends of the spring tube 602, and the spring buckles can be clamped inside the connecting port to connect the spring tube 602 between two adjacent protection plates 201, protecting the outside of the spring-shaped metal wire 2, thereby further protecting the cable unit. At the same time, both the spring tube 602 and the spring-shaped metal wire 2 can be bent, enabling the cable unit to be bent to meet different laying requirements.

[0062] To further reduce the impact on the cable, a plurality of balls 1 are rotatably connected to the connecting block. An installation component is arranged outside the outer sheath 103. The installation component is used to limit the cable unit. The installation component includes an installation ring 701 and a vacuum sucker 702. The installation ring 701 is installed outside a group of protection plates 201 among multiple groups of protection plates 201 through a plurality of installation springs 703. A plurality of vacuum suckers 702 are provided, and the vacuum suckers 702 are fixedly connected to the outside of the installation ring 701 at equal angles. Pressing the vacuum suckers 702 can make the vacuum suckers 702 adsorb on a flat ground or wall surface to limit the low-voltage cable, enabling the cable unit to be laid along a certain trajectory. At the same time, the installation ring 701 can further protect the outside of the cable unit. The balls 1 are in contact with the ground. When the cable unit is subjected to an external impact, the cable unit can move to a certain extent, avoiding the cable unit completely bearing the impact at a fixed position. The rotation of the balls 1 facilitates the movement of the cable unit. The cable unit can offset a certain distance to reduce the impact force and move away from the object applying the external force, thereby further improving the protection of the cable unit.

[0063] The working principle or usage process of the impact-resistant and buffer-type low-voltage cable is as follows:

[0064] According to the laying requirements, select an appropriate number of cable units. Insert the connector 301 into the inside of the connection socket 302, insert the plug 303 into the inside of the socket 304, and insert the limiting block 402 into the limiting port. When the connector 301 and the connection socket 302 are in close contact, the limiting block 402 passes through the limiting port and rebounds under the action of the elastic plate 403, and the limiting block 402 is in close contact with the limiting seat 401 to prevent the limiting block 402 from detaching, thereby ensuring the stability of the connection between the plug 303 and the socket 304.

[0065] Press the vacuum suction cup 702 to make it adsorb on a flat ground or wall surface to limit the laying trajectory of the cable unit. Connect the spring tube 602 between the connection blocks 601 through the spring snap, and protect the outside of the cable unit through the spring tube 602, the protection plate 201 and the spring-shaped metal wire 2;

[0066] When being impacted externally, the cable unit can offset a certain distance away from the object applying the impact. At the same time, the buffer spring 203 and the buffer block 202 buffer the impact, and the telescopic rod 204 absorbs the impact force to reduce the damage to the wire core 101 inside the cable unit.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
