Description

Technical Field

[0001] This utility model relates to the field of cable joint technology, specifically to a power cable with a reinforced cable joint. Background Technology

[0002] A cable is an electrical energy or signal transmission device made of one or more mutually insulated conductors and an outer insulating protective layer. It is usually composed of several or several groups of wires. Cables are an important component in various intelligent devices. A connector is a device that allows two cables to be connected together when splicing them.

[0003] In the existing technology, connectors are mostly connected to each other by threads. However, at the current cable connection, loosening may occur over a long period of time or under the action of external force. Therefore, there is an urgent need for a power cable with reinforced cable joints. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a power cable with a reinforced cable joint, comprising a cable body, and an anti-detachment mechanism provided on the outer side between two sets of the cable bodies;

[0006] The anti-detachment mechanism includes a first connecting pipe and a second connecting pipe. A threaded pipe is fixedly connected to the inner side of the bottom wall of the second connecting pipe. An installation ring is fixedly connected to the outer side of the opposite end of the first connecting pipe and the second connecting pipe. Multiple sets of annularly distributed slots are provided on the outer periphery of the opposite side wall of the two sets of installation rings. A clamping plate is provided on the inner side of each slot. The clamping plate is fixedly connected to a threaded block. The threaded block is threaded to the upper and lower sides of the outer periphery of the bidirectional screw. The bidirectional screw is rotatably connected to the middle of the inner side of the installation groove.

[0007] In a preferred embodiment of this utility model, the mounting grooves are all located in the middle of the mounting plate, and the mounting plates are all located on the outside of the first connecting pipe and the second connecting pipe and are distributed in a ring.

[0008] As a preferred embodiment of this utility model, the clamps are all fitted with the slots with a clearance, and the mounting rings are all rotatably connected to the outer sides of the two sets of cable bodies at one close end.

[0009] As a preferred embodiment of this utility model, a sealing ring is provided on the outer side of the connection between the first connecting pipe and the second connecting pipe. The sealing ring is in clearance fit with the second connecting pipe and the second connecting pipe, and the sealing ring is located in the middle between the two sets of mounting rings.

[0010] As a preferred embodiment of this utility model, each of the mounting plates has a knob rotatably connected to the center of its top wall, and each knob is fixedly connected to a bidirectional screw.

[0011] As a preferred embodiment of this utility model, the diameter and length of the first connecting pipe and the second connecting pipe are equal, and both the first connecting pipe and the second connecting pipe are clearance-fitted with the cable body.

[0012] In a preferred embodiment of this utility model, the second connecting pipe is threadedly connected to the first connecting pipe via a threaded pipe, and the inner diameter of the mounting ring is equal to the inner diameter of both the first and second connecting pipes.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of power cable with reinforced cable joint, after the cable joint is installed, moves the mounting plate to the outside of the first connecting pipe and the second connecting pipe, and then rotates the knob. During the rotation of the knob, the threaded blocks on both sides move closer to each other, thereby pushing the upper and lower mounting rings on both sides closer to each other as the clamping plates move closer to each other, thereby applying pressure to the first connecting pipe and the second connecting pipe to move closer to each other, reducing the possibility of the cable joint loosening.

[0015] 2. This type of power cable with reinforced cable joint has a sealing ring installed on its outer side before the first connecting pipe and the second connecting pipe are connected. After the first connecting pipe and the second connecting pipe are connected, the sealing ring is heated so that the sealing ring shrinks and fits at the connection between the first connecting pipe and the second connecting pipe, which further enhances the connection strength and sealing performance of the cable joint.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a power cable with a reinforced cable joint, comprising a cable body 1, and an anti-detachment mechanism 2 provided on the outer side between two sets of cable bodies 1;

[0024] The anti-detachment mechanism 2 includes a first connecting pipe 4 and a second connecting pipe 5. A threaded pipe 6 is fixedly connected to the inner side of the bottom wall of the second connecting pipe 5. An installation ring 3 is fixedly connected to the outer side of the opposite end of the first connecting pipe 4 and the second connecting pipe 5. The installation ring 3 serves to connect the cable body 1 to the first connecting pipe 4 or the second connecting pipe 5. Multiple sets of annularly distributed slots 8 are provided on the outer periphery of the opposite side wall of the two sets of installation rings 3. A clamping plate 13 is provided on the inner side of the slot 8. The clamping plate 13 is located inside the slot 8 and pushes the upper and lower sets of installation rings 3 closer to each other. The clamping plate 13 is fixedly connected to the threaded block 12. The threaded block 12 is threadedly connected to the upper and lower sides of the outer periphery of the bidirectional screw 11. The bidirectional screw 11 is rotatably connected to the middle of the inner side of the installation groove 10. During the rotation of the bidirectional screw 11, it can drive the upper and lower sets of threaded blocks 12 to approach each other.

[0025] The mounting slots 10 are all located in the middle of the mounting plate 9. The mounting plates 9 are all located on the outside of the first connecting pipe 4 and the second connecting pipe 5 and are distributed in a ring. The clamping plates 13 are all fitted with the slots 8 with clearance. The mounting rings 3 are all rotatably connected to the outside of the two sets of cable bodies 1 at one close side. The mounting plate 9 provides space for the installation of the anti-detachment mechanism 2.

[0026] A sealing ring 7 is provided on the outside of the connection between the first connecting pipe 4 and the second connecting pipe 5. The sealing ring 7 is in clearance fit with the first connecting pipe 4 and the second connecting pipe 5. The sealing ring 7 is located in the middle between the two sets of mounting rings 3. A knob 14 is rotatably connected to the middle of the top wall of the mounting plate 9. The knob 14 is fixedly connected to the bidirectional screw 11. When heated, the sealing ring 7 will shrink and fit against the connection between the first connecting pipe 4 and the second connecting pipe 5.

[0027] The diameter and length of the first connecting pipe 4 and the second connecting pipe 5 are equal. The first connecting pipe 4 and the second connecting pipe 5 are both clearance-fitted with the cable body 1. The second connecting pipe 5 is threadedly connected to the first connecting pipe 4 through the threaded pipe 6. The inner diameter of the mounting ring 3 is equal to the inner diameter of the first connecting pipe 4 and the second connecting pipe 5. The cooperation of the first connecting pipe 4 and the second connecting pipe 5 can isolate and protect the connection point of the two sets of cable bodies 1.

[0028] Working principle: Before the first connecting pipe 4 and the second connecting pipe 5 are connected, a sealing ring 7 is set on their outer side. After the first connecting pipe 4 and the second connecting pipe 5 are connected, the sealing ring 7 is heated, causing the sealing ring 7 to shrink and fit against the connection between the first connecting pipe 4 and the second connecting pipe 5, which further strengthens the connection strength and sealing of the cable joint. After the cable joint is installed, the mounting plate 9 is moved to the outside of the first connecting pipe 4 and the second connecting pipe 5. Then, the knob 14 is rotated. During the rotation of the knob 14, the threaded blocks 12 on both sides are brought closer to each other, which pushes the upper and lower mounting rings 3 closer to each other as the clamping plates 13 are brought closer to each other, thereby applying pressure to the first connecting pipe 4 and the second connecting pipe 5 to bring them closer together, reducing the possibility of the cable joint loosening.
