Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and more specifically to a convenient power cable connector. Background Technology

[0002] Cable connectors, also known as cable heads, are an indispensable component of cable lines. During cable laying, cable connectors are needed to connect cable segments into a continuous line. These connectors not only lock and secure the incoming and outgoing lines, but also provide waterproofing, dustproofing, and vibration damping. Furthermore, cable connectors ensure the insulation level at the cable joint, guaranteeing the safe and reliable operation of the cable line.

[0003] However, when connecting cables, the existing power cable connectors may be in a bent state at both ends. In this bent state, the existing connectors are prone to deformation or damage due to insufficient structural strength. At the same time, the bent cables will squeeze the connection point of the connector, resulting in gaps at the connection point and affecting the stability of the cable connection after use. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a convenient power cable connector to solve the problem that traditional connectors cannot avoid the cable in a bent state from squeezing the connection of the connector, resulting in deformation or damage of the connector due to bending stress, and at the same time, causing gaps at the connection, which affects the stability of the cable after connection.

[0005] This utility model provides the following technical solution: a convenient power cable connector, comprising two cable bodies, an insulating layer and a first conductor provided in the inner cavity of each cable body, a protective sleeve provided between the two cable bodies, a bending force-bearing component sleeved on one side of the surface of each cable body, and connection end components for connecting the two cable bodies fixedly connected to both sides of the inner cavity of the protective sleeve. The bending force-bearing component includes a bellows hose sleeved on the surface of the cable body, and the inner wall of the bellows hose is fixedly connected with an elastic reinforcement. The connection end assembly includes a sealing tube that is fixedly connected to the protective sleeve. A plug block is fixedly connected to one end of the inner cavity of the sealing tube near the protective sleeve, and a connecting rod is fixedly connected to one end of the inner cavity of the sealing tube near the cable body. A sealing groove is formed on the surface of the connecting rod, and a sealing ring is fixedly connected to the inner cavity of the sealing groove.

[0006] Preferably, the elastic reinforcement is evenly distributed in a spiral shape on the inner wall of the bellows hose and sleeved on the surface of the cable body, and the elastic reinforcement is made of metal.

[0007] Preferably, a sealing connecting block is fixedly connected to one end of the bellows hose near the sealing tube, the inner wall of the sealing connecting block is threadedly connected to the surface of the connecting rod, and the bellows hose communicates with the inner cavity of the sealing tube through the sealing connecting block and the connecting rod.

[0008] Preferably, the position of the sealing groove corresponds to the position of the sealing connecting block, and the sealing ring is located between the sealing connecting block and the connecting rod.

[0009] Preferably, the surface of the plug block is provided with heat dissipation grooves, and the inner cavity is provided with through holes.

[0010] Preferably, the two connecting end components are positioned correspondingly and connected, and a second conductor is inserted into the inner cavity of the two plug blocks. The end of the first conductor near the protective sleeve passes through the connecting rod, the sealing tube and the plug block in sequence, and is connected to the second conductor.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model incorporates a bending force-bearing component to withstand the pressure generated when the cable is bent. The freely bendable bellows hose adjusts its angle according to the cable's bending condition, ensuring accurate connection even when the cable is bent. This prevents deformation or even breakage of the pressure-bearing portion of the connection end component due to the bent cable, thus avoiding gaps between the cable body and the connection end component. Furthermore, the elastic metal reinforcement increases the strength and support of the bellows hose, preventing large-diameter cables from experiencing excessive rebound force after bending, which could prevent the bellows hose from bending to the appropriate angle. It also avoids deformation of the bellows hose due to prolonged bending, effectively improving the service life of the bending force-bearing component.

[0012] 2. This utility model increases the sealing performance of the connection between the bellows hose and the sealing tube by providing a sealing groove and a sealing ring. At the same time, the two connection end components are connected by a protective sleeve, which increases the protection effect of the connection between the two cables and prevents water ingress from affecting the normal use of the cables after connection. In addition, each structure can be disassembled and the modular design makes the connector structure easy to carry and more convenient to use. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The convenient power cable connector involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] This utility model provides a convenient power cable connector, such as Figure 1 - Figure 4 As shown, the cable includes two cable bodies 1. The inner cavity of each cable body 1 is provided with an insulation layer 2 and a first conductor 3. A protective sleeve 4 is provided between the two cable bodies 1. A bending force-bearing component 5 is fitted on one side of the surface of each cable body 1. Connecting end components 6 for connecting the two cable bodies 1 are fixedly connected to both sides of the inner cavity of the protective sleeve 4. The two cable bodies 1 that need to be connected are connected through the connecting end components 6. The protective sleeve 4 increases the protection effect at the connection between the two cable bodies 1, preventing water ingress and other situations from affecting the normal use of the cable after connection. At the same time, it adopts a modular design, and each structure can be disassembled, making it easy to carry and use.

[0020] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the bending force-bearing component 5 includes a bellows hose 51 sleeved on the surface of the cable body 1. An elastic reinforcement 52 is fixedly connected to the inner wall of the bellows hose 51. The bellows hose 51 can be bent at will to adjust the bending angle. The bellows hose 51 can be adjusted according to the bending condition of the cable to avoid the inability of traditional connector structures to bend, which would cause the connection between the two cables to be unable to be accurately aligned when bent. Through the structure that the bellows hose 51 can be bent at will, the connected cables can also complete the accurate connection operation in the bent state. Furthermore, the elastic reinforcement 52 increases the support strength and bending force strength of the bellows hose 51.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, the connection end assembly 6 includes a sealing tube 61 that is fixedly connected to the protective sleeve 4. A plug block 62 is fixedly connected to one end of the inner cavity of the sealing tube 61 near the protective sleeve 4, and a connecting rod 63 is fixedly connected to one end of the inner cavity of the sealing tube 61 near the cable body 1. A sealing groove 64 is formed on the surface of the connecting rod 63, and a sealing ring 65 is fixedly connected to the inner cavity of the sealing groove 64. The sealing effect after the cable connection is increased by the sealing groove 64 and the sealing ring 65.

[0022] Furthermore, such as Figure 3 As shown, the elastic reinforcement 52 is evenly distributed in a spiral shape on the inner wall of the bellows hose 51 and is sleeved on the surface of the cable body 1. The elastic reinforcement 52 is made of metal. After the two cable bodies 1 are connected, the cable part inserted into the inner cavity of the connecting end component 6 will be squeezed against the connecting part of the connecting end component 6 when it is bent. If it is bent for a long time, the stress-bearing part of the connecting end component 6 will deform or even break, resulting in gaps at the connection between the cable body 1 and the connecting end component 6, which will affect the normal use of the cable. At the same time, the elastic reinforcement 52 made of metal increases the stress and support strength of the bellows hose 51, preventing the large rebound force after bending of cables with larger diameters, which would prevent the bellows hose 51 from bending to a suitable angle. It can also avoid the bellows hose 51 from deforming due to long-term bending, effectively improving the service life of the bending stress component 5.

[0023] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, a sealing connecting block 53 is fixedly connected to one end of the bellows hose 51 near the sealing tube 61. The inner wall of the sealing connecting block 53 is threadedly connected to the surface of the connecting rod 63. The bellows hose 51 communicates with the inner cavity of the sealing tube 61 through the sealing connecting block 53 and the connecting rod 63. After the bellows hose 51 is sleeved on the surface of the cable body 1, the connection point on the side away from the connecting end assembly 6 is fixed with insulating tape or heat fusion to ensure sealing. The bellows hose 51 and the sealing tube 61 are first connected together by threads, which makes it easier to disassemble and assemble the components.

[0024] Furthermore, such as Figure 4 As shown, the position of the sealing groove 64 corresponds to the position of the sealing connecting block 53, and the sealing ring 65 is located between the sealing connecting block 53 and the connecting rod 63. The sealing effect after the connection between the bellows hose 51 and the sealing tube 61 is enhanced by the sealing groove 64 and the sealing ring 65.

[0025] Furthermore, such as Figure 2As shown, the surface of the plug block 62 is provided with heat dissipation grooves 66, and the inner cavity is provided with through holes. The heat dissipation grooves 66 increase the heat dissipation effect of the connector and reduce the overall weight of the connector.

[0026] Furthermore, such as Figure 2 As shown, the two connection end components 6 are positioned correspondingly and connected. A second conductor 7 is inserted into the inner cavity of the two plug blocks 62. The end of the first conductor 3 near the protective sleeve 4 passes through the connecting rod 63, the sealing tube 61 and the plug block 62 in sequence, and is connected to the second conductor 7. The two cable bodies 1 are respectively connected to the corresponding connection end components 6. After the first conductor 3 inserted in the inner cavity of the connection end component 6 is fixed, it is connected to the second conductor 7, thus realizing the electrical connection between the two cables.

[0027] The working principle of this utility model is as follows: First, the bellows hose 51 is fitted onto the surface of the cable body 1. Then, the first conductors 3 of the inner cavities of the two cable bodies 1 to be connected are sequentially passed through the connecting rod 63, the sealing tube 61, and the central axis of the plug block 62 until they are connected to the second conductor in the middle. After the first conductors 3 in the cable bodies 1 on both sides are connected, the bellows hose 51 is connected to the inner cavity of the sealing tube 61 by the threaded connection of the sealing connecting block 53 and the connecting rod 63. The connection point on the side away from the connecting end assembly 6 is fixed to the surface of the cable body 1 using insulating tape or heat fusion to ensure sealing. The sealing effect after connection is enhanced by the sealing groove 64 and the sealing ring 65 between the bellows hose 51 and the sealing tube 61. After connection, the bending angle of the bellows hose 51 can be adjusted according to the specific bending situation of the cable. The flexible bending structure of the bellows hose 51 allows for easy bending of the connected cable. Even when the cable is bent, accurate connection can be achieved. The elastic reinforcement 52 increases the support strength and bending stress resistance of the bellows hose 51. Because a bent cable can compress the connection point of the connector assembly 6, prolonged bending can cause deformation or even breakage of the load-bearing portion of the connector assembly 6, resulting in gaps between the cable body 1 and the connector assembly 6, affecting the normal use of the cable. Therefore, the bellows hose 51 is adjusted according to the cable's bending condition. Simultaneously, the metal elastic reinforcement 52 increases the load-bearing and support strength of the bellows hose 51, preventing large-diameter cables from having excessive rebound force after bending, which could prevent the bellows hose 51 from bending to the appropriate angle. It also avoids deformation of the bellows hose 51 due to prolonged bending, effectively improving the service life of the bending stress component 5.
