Description

Technical Field

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

[0002] Cable is a wire product used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. It can be defined as a collection of the following parts: one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. Cables can be divided into high-voltage cables and low-voltage cables according to voltage. Low-voltage cables are extremely susceptible to external interference during use.

[0003] The low-voltage cables currently on the market only rely on the armor layer and insulation layer of the cable itself for protection, lack of proprietary protection structure, and have poor resistance to external interference. When subjected to external interference such as impact, pulling and shearing, they are easily damaged or even broken. In addition, the joints of the cables are also prone to loosening, falling off or even breaking due to external impact, affecting the normal use of the cables, and are prone to electric shock accidents and even fires. Therefore, we propose an anti-collision buffered low-voltage cable that 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

The limit block is wedge-shaped and is close to the connection seat and one end of the limit block is in contact with the limit seat.

[0006] In order to release the limit of the connection component by the limit assembly, a disassembly assembly is also included, and the disassembly assembly is used to release the limit of the limit seat on the limit block, and the disassembly assembly includes: A sliding seat, the sliding seat is fixedly connected to the connecting head; A pressing plate, the pressing plate is slidably connected to the sliding seat via a sliding rod, the pressing plate is in contact with the limiting block, and a return spring is provided between the pressing plate and the sliding seat; A pull rope, wherein one end of the pressing plate away from the limiting block is fixedly connected to a rope ring, and the pull rope passes through a plurality of the rope rings; A torsion block is fixedly connected to the pull rope.

[0007] In order to further protect the cable, an auxiliary protection component is also included, and the auxiliary protection component includes: A connecting block, two connecting blocks are fixedly connected to the protective plate; A spring tube, both ends of which are detachably connected to the connecting blocks on two adjacent protective plates.

[0008] In order to further reduce the collision of the cable, a plurality of balls are rotatably connected to the connection block, and a mounting assembly is arranged outside the outer sheath, and the mounting assembly is used to limit the position of the cable unit, and the mounting assembly includes: A mounting ring, the mounting ring being mounted outside a set of protective plates among the plurality of sets of protective plates through a plurality of mounting springs; A vacuum suction cup is provided in plurality and is fixedly connected to the outside of the mounting ring at equal angles.

[0009] In order 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 components are arranged in an alternating manner.

[0010] The working principle and beneficial effects of the present invention are: 1. In the present invention, the outer sheath of the cable unit is protected against installation by a protective plate, and the impact force is buffered by a buffer block and a buffer spring. The impact force is absorbed by the extension and contraction of the telescopic rod and the deformation of the buffer block, thereby reducing the damage to the wire core caused by the impact force transmitted to the inside of the cable unit. At the same time, the cable unit between two adjacent groups of protective plates is protected by a spring-shaped metal wire to reduce the puncture and impact damage of the outer sheath by foreign objects. At the same time, the outside of the protective plate and the spring-shaped metal wire are protected by a spring tube, thereby further improving the protection of the cable unit.

[0011] 2. In the present invention, the plug and the socket are plugged together through the sliding fit of the connector and the connector seat, and the two cable units are electrically connected. During the connection process of the connector and the connector seat, the limit block is inserted into the limit opening of the limit seat. The elastic plate is bent when the limit block is inserted into the limit opening. After the limit block passes through the limit opening, the elastic plate rebounds to its original position. The limit block contacts the limit seat, and the connector and the connector seat are limited to ensure the stability of the connection between the plug and the socket.

[0012] 3. In the present invention, when the cable unit needs to be disassembled, the torsion block is rotated to wrap around the pull rope, the pull rope is tightened to press the pressing plate, and the pressing plate presses the limit block to make the limit block enter the interior of the limit opening, so that the connector and the connecting seat can be separated, the torsion block is loosened, and the pressing plate is moved away from the sliding seat under the action of the reset spring to avoid obstruction to the limit block.

[0013] 4. In the present invention, when laying the cable, the vacuum suction cup is adsorbed on the ground or wall, and the mounting ring protects the outside of the cable unit. When impacted by external force, the cable unit can move inside the mounting ring, and the cable unit is moved by the rotation of the ball. Compared with the cable unit being in a fixed state and directly bearing the external force, the present invention avoids the impact force to a certain extent by moving the cable unit, thereby reducing cable damage.

[0014] 4. Therefore, compared with the low-voltage cable in the prior art, the present invention protects the outside of the outer sheath by a protective plate and a spring-shaped metal wire, and at the same time, the spring tube protects the outside of the protective plate and the spring-shaped metal wire, and fixes the mounting ring at the mounting position by a vacuum suction cup to control the direction of the cable unit, and provides further protection for the outside of the protective plate by the mounting ring and the mounting 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 mounting spring, reducing direct resistance to external force, thereby protecting the cable unit, and ensuring the stability of the connection between the connector and the connector seat and between the plug and the socket through the cooperation of the limit block and the limit seat, thereby avoiding the electrical connection of the cable unit from being disconnected when subjected to impact, and winding the pull rope by the torsion block so that the pull rope presses the pressing plate, and pressing the limit block into the inside of the limit opening, so that the connector seat and the connector can be separated, and the cable unit can be disassembled.

[0020] The protection component is arranged on the outside of the outer sheath 103, and the protection component includes a protection plate 201 and a buffer block 202. The protection plate 201 is arranged on the outside of the outer sheath 103 through a plurality of buffer springs 203 and a plurality of telescopic rods 204. The protection plate 201 is provided with multiple groups, and each group of protection plates 201 is provided with multiple protection plates. The multiple protection plates 201 in a single group are arranged at the same angle on the outside of the outer sheath 103.

[0022] The limiting assembly is used to limit the connection components after connection. The limiting assembly includes a limiting seat 401 and a limiting block 402. The limiting seat 401 is fixedly connected to the outside of the connector 301. The limiting seat 401 is provided with a limiting opening. The limiting block 402 is fixedly connected to one end of the connector 302 close to the connector 301 through an elastic plate 403. The limiting block 402 is wedge-shaped. The limiting block 402 is close to the connector 302 and one end is in contact with the limiting seat 401. During the connection between the connector 301 and the connector seat 302, the limiting block 402 is close to the limiting seat 401, and the tip of the limiting block 402 is inserted into Inside the limiting opening, as the limiting block 402 moves, the side of the limiting block 402 with a larger thickness gradually enters the limiting opening, and the elastic plate 403 bends when the limiting opening presses the limiting block 402. When the connector 301 and the connector 301 are tightly and completely connected, the limiting block 402 passes through the limiting opening, and the limiting block 402 rebounds under the action of the elastic plate 403. The end of the limiting block 402 with a larger thickness contacts the limiting seat 401, limiting the connector 301 and the connector seat 302 to prevent the two from separating when hit by external force, thereby ensuring the stability of the connection between the two cable units.

[0023] In order to release the limit of the limiting component on the connecting component, a disassembly component is also included, which is used to release the limit of the limiting seat 401 on the limiting block 402.

The end of the pressing plate 502 away from the limiting block 402 is fixedly connected with a rope ring 507. The pull rope 503 passes through multiple rope rings 507, and the torsion block 504 is fixedly connected to the pull rope 503. Initially, under the action of the reset 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 between the two cable units, rotate the torsion block 504 to wind and reel the pull rope 503, so that the total length of the pull rope 503 is reduced, and the rope ring 507 composed of the pull rope 503 is contracted, and a force toward the center is applied to the pressing plate 502, that is, the pressing plate 502 is pressed, so that the pressing plate 502 presses the limit block 402, and the limit block 402 is pressed into the position corresponding to the limit opening, and the connector 301 and the connecting seat 302 are pulled out of the inside of the limit opening, and the plug 303 and the socket 304 are separated, so that the total length of the low-voltage cable can be adjusted, and the damaged cable unit can be replaced in time. Compared with the method of replacing the entire section of the cable due to damage in a certain part, the replacement cost can be reduced by connecting multiple cable units.

[0024] In order to further protect the cable, an auxiliary protection component is also included, which includes a connecting block 601 and a spring tube 602.

[0025] In order to further reduce the collision of the cable, a plurality of balls 1 are rotatably connected to the connection block, a mounting assembly is arranged outside the outer sheath 103, the mounting assembly is used to limit the cable unit, the mounting assembly includes a mounting ring 701 and a vacuum suction cup 702, the mounting ring 701 is mounted on the outside of a group of protective plates 201 in the plurality of protective plates 201 through a plurality of mounting springs 703, a plurality of vacuum suction cups 702 are arranged, and the vacuum suction cups 702 are fixedly connected to the outside of the mounting ring 701 at equal angles, and the vacuum suction cups 702 can be pressed to make the vacuum suction cups 702 suck Attached to the flat ground or wall, it limits the position of the low-voltage cable and allows the cable unit to be laid along a certain trajectory. At the same time, the mounting ring 701 can further protect the outside of the cable unit. The ball 1 is in contact with the ground. When the cable unit is impacted by external force, the cable unit can move to a certain extent to avoid the cable unit being in a fixed position and fully bearing the impact. The rotation of the ball 1 facilitates the movement of the cable unit. The cable unit can be offset by a certain distance to reduce the impact force it receives and stay away from objects that apply external force, thereby further improving the protection of the cable unit.

[0026] The working principle or use process of the anti-collision buffered low-voltage cable is as follows: According to the laying requirements, a suitable number of cable units are selected, the connector 301 is inserted into the interior of the connector seat 302, the plug 303 is inserted into the interior of the socket 304, and the limit block 402 is inserted into the interior of the limit opening. When the connector 301 and the connector seat 302 are in close contact, the limit block 402 passes through the limit opening and rebounds under the action of the elastic plate 403. The limit block 402 and the limit seat 401 are in close contact to prevent the limit block 402 from being separated, thereby ensuring the stability of the connection between the plug 303 and the socket 304; Press the vacuum suction cup 702 to make it adsorb on the flat ground or wall to limit the laying track of the cable unit, connect the spring tube 602 between the connecting blocks 601 through the spring buckle, and protect the outside of the cable unit through the spring tube 602, the protective plate 201 and the spring-shaped metal wire 2; When subjected to external impact, the cable unit can be offset by 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, thereby reducing damage to the wire core 101 inside the cable unit.
