Description

Technical Field

[0001] This utility model relates to the field of pre-branched cables, specifically a pre-branched waterproof wire and cable. Background Technology

[0002] In the field of building electrical wiring and power transmission, pre-branched wires and cables are widely used due to their advantages such as saving space and simplifying the installation process. However, traditional pre-branched cables have significant defects in terms of waterproof sealing and compatibility with branching operations.

[0003] Conventional pre-branched cables often have poor sealing at the pre-branching points. When the cable does not require branching, the pre-branching interface is often simply wrapped or heat-shrinked, which is insufficient to withstand harsh environments such as long-term humidity and immersion. Moisture can easily seep into the cable core along the interface, leading to insulation aging, short circuits, and other faults. Especially in high-humidity environments such as underground garages and tunnels, waterproofing failures occur frequently, seriously threatening the safety of power transmission. On the other hand, if traditional cables need to be branched out, the original sealing structure must be destroyed, and the wires must be stripped, reconnected, and waterproofed again. This operation is cumbersome and time-consuming, and can easily damage the cables. Therefore, a pre-branched waterproof wire and cable needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pre-branched waterproof wire and cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pre-branched waterproof wire and cable, comprising multiple cables, wherein two insulating layers are sleeved on the outer side of the multiple cables, and a reserved portion is provided between the two insulating layers of the cables;

[0006] A connecting cover is fixedly installed on one side of each of the two insulating layers, and a sealing cover for sealing the reserved part is fixedly connected between the two connecting covers. A cable exit assembly is provided on the surface of one of the connecting covers.

[0007] Preferably, the reserved portion is formed by bending a cable, and the reserved portion passes between the sealing cover and the two connecting covers.

[0008] Preferably, a filler rope is provided between the cable and the insulation layer.

[0009] Preferably, the cable exit assembly includes multiple connection holes, each connection hole is opened on one side of the connection cover surface, a sealing post passes through the connection hole, a connector is fixedly installed on one side of the sealing post, the connector is fixed to the connection cover by screws, and a sealing assembly is provided between the sealing post and the connection cover.

[0010] Preferably, the outer diameter of the sealing column is appropriately matched with the inner diameter of the connecting hole.

[0011] Preferably, the sealing assembly includes a pressure sleeve and a sealing gasket. The pressure sleeve is fixedly installed on the outside of the sealing column, and the sealing gasket is bonded to one side of the pressure sleeve. One side of the sealing gasket is in close contact with the connecting cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This pre-branched waterproof cable has a reserved section for subsequent branch connection during installation. The reserved section is sealed by a connecting cover, a sealing cover, and the reserved section itself. The connection hole is sealed by a sealing post, a pressure sleeve, and a sealing gasket. This effectively prevents moisture from seeping into the cable core along the reserved section, which could lead to insulation aging, short circuits, and other faults.

[0014] 2. When connecting branch cables, this pre-branched waterproof cable separates the connector from the connector cover by unscrewing the screws, allowing the sealing post to detach from the connection hole. This facilitates pulling out a portion of the pre-reserved part from the connection hole, making it easier to connect the branch cables. After connection, the connection hole is sealed with hot melt adhesive or other sealing methods to complete the resealing operation, effectively preventing moisture from entering the branch cable connection. The pre-reserved part, which extends out of the connection hole, makes connecting branch cables more convenient and improves connection efficiency. Attached Figure Description

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.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a pre-branched waterproof wire and cable, including multiple cables 1, with two insulation layers 2 sleeved on the outside of the multiple cables 1, and a reserved part 5 provided between the two insulation layers 2 of the cables 1;

[0023] A connecting cover 3 is fixedly installed on one side of the two insulating layers 2, and a sealing cover 4 for sealing the reserved part 5 is fixedly connected between the two connecting covers 3. A cable exit assembly is provided on the surface of one connecting cover 3.

[0024] Specifically, the space of the reserved portion 5 is sealed by the connecting cover 3, the sealing cover 4 and the reserved portion 5. The reserved portion 5 can be passed to the outside through the cable passing component, which facilitates the operator to perform branch wiring operations and improves the efficiency of branch wiring.

[0025] The reserved part 5 is formed by bending the cable 1, and the reserved part 5 passes between the sealing cover 4 and the two connecting covers 3. The reserved part 5 has a certain length, so that it can be easily passed out from between the sealing cover 4 and the two connecting covers 3 to the outside, which is convenient for operators to perform branch wiring operations.

[0026] Among them, a filler rope is provided between cable 1 and insulation layer 2 to fill the space between cable 1 and insulation layer 2.

[0027] The cable exit assembly includes multiple connection holes 6, which are located on the surface of one side of the connection cover 3. A sealing post 7 passes through the inside of the connection hole 6. A connector 10 is fixedly installed on one side of the sealing post 7. The connector 10 is fixed to the connection cover 3 by screws. A sealing assembly is provided between the sealing post 7 and the connection cover 3. The outer diameter of the sealing post 7 is appropriately matched with the inner diameter of the connection hole 6. The sealing assembly includes a pressure sleeve 8 and a sealing gasket 9. The pressure sleeve 8 is fixedly installed on the outside of the sealing post 7. The sealing gasket 9 is adhered to one side of the pressure sleeve 8 and has close contact with the connection cover 3. The connection hole 6 is sealed by the sealing post 7, the pressure sleeve 8, and the sealing gasket 9, which can effectively prevent moisture from seeping into the cable core along the reserved part 5, causing insulation aging, short circuits, and other faults. By unscrewing the screws, the connector 10 can be separated from the connection cover 3, allowing the sealing post 7 to be removed from the connection hole 6. This makes it easier to pull out part of the reserved part 5 from the connection hole 6, thus facilitating the connection of branch cables.

[0028] Working principle: This utility model is a pre-branched waterproof wire and cable. During installation, a reserved part 5 is reserved as a subsequent branch connection part. The space of the reserved part 5 is sealed by the connecting cover 3, the sealing cover 4 and the reserved part 5. The connecting hole 6 is sealed by the sealing post 7, the pressure sleeve 8 and the sealing gasket 9. This can effectively prevent water vapor from seeping into the cable core along the reserved part 5, which could lead to insulation aging, short circuit and other faults.

[0029] When it is necessary to connect a branch cable, the connector 10 is separated from the connector cover 3 by unscrewing the screw, so that the sealing post 7 can be removed from the connector hole 6. This makes it easy to pull out part of the reserved part 5 from the connector hole 6, which facilitates the connection of the branch cable. After the connection is completed, the connector hole 6 is sealed by sealing means such as hot melt adhesive, which can complete the resealing operation and effectively prevent moisture from entering the connection of the branch cable.
