Description

Technical Field

[0001] The present invention relates to the technical field of cable and wire connection, and in particular to a cable brancher and a cable connection device with prefabricated gel protection. Background Art

[0002] Cable splicing refers to the process of connecting cables in sections to form a continuous cable run. This primarily involves splicing the cable core and sheath. The splicing of various cable cores must ensure mechanical strength and electrical performance at the splice point. The splicing of the cable sheath must ensure a tight seal to prevent moisture and humidity intrusion.

[0003] Cable splicing is often necessary during cable line construction and maintenance. Existing cable splitters typically include an insulating base and a conductive clamp. The clamp is provided with two through-slots for mounting the main cable and branch cables, respectively. Multiple conductive screws are then used to press and lock the main and branch cables. Furthermore, the narrow openings of the through-slots, which require the installation of the conductive screws, make it difficult to insert the cables quickly and accurately. This makes installation cumbersome and time-consuming, hindering construction efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a cable splitter and a cable connection device with prefabricated gel protection, which are easy to install, have high construction efficiency, good waterproof and moisture-proof effects, long service life, high safety in use, easy replacement, environmentally friendly and simple construction.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cable brancher, comprising: an insulating seat, at least two assembly grooves are arranged at intervals on the insulating seat, and at least two conductive wire clamps are arranged in the assembly grooves, the conductive wire clamps include: a conductive seat arranged in the assembly groove; a through groove is provided on the conductive seat for the wire to pass through, and a slide groove is provided axially on the inner wall of the through groove; a conductive screw plate slidably assembled in the slide groove; and a conductive screw that passes through the conductive screw plate to press the wire.

[0006] The conductive screw plate is provided with a boss, and the conductive screw plate can be assembled in the slide groove with the boss facing toward or facing away from the through groove to reduce or increase the volume of the through groove.

[0007] The conductive screw plate is in a dovetail shape near the end of the chute, and the chute is correspondingly configured to be in a dovetail shape.

[0008] The conductive wire clamp further includes a wire pressing plate arranged between the conductive screw and the wire.

[0009] There are at least three assembly grooves, and a portion of the assembly grooves is perpendicular to another portion of the assembly grooves and is arranged on the insulating seat.

[0010] A cable connection device with prefabricated gel protection comprises: a cable branch; and a prefabricated gel waterproof box for assembling the cable branch.

[0011] The prefabricated gel waterproof box includes: a bottom shell; and an upper cover arranged on the bottom shell; the bottom shell and the upper cover are pre-filled with power silicone gel, and the power silicone gel is used to wrap the cable brancher; both ends of the bottom shell are provided with a first gel baffle, and both ends of the upper cover are provided with a second gel baffle used in conjunction with the first gel baffle; the bottom shell is provided with a limiting structure for limiting the cable brancher.

[0012] The limiting structure includes: a plurality of transverse limiting blocks and longitudinal limiting blocks arranged on the bottom shell; and a positioning hole arranged on the bottom shell for inserting a positioning pin arranged on the bottom of the cable splitter.

[0013] The first gel baffle and the second gel baffle are both serrated baffles, and the teeth of the serrated baffles are arranged outwards.

[0014] One side of the upper cover is hinged to one side of the bottom shell, and the other side is buckled by a buckle, and the ends of the buckled sides of the upper cover and the bottom shell are correspondingly provided with cable tie reserved holes.

[0015] After adopting the above technical solution, the beneficial effects of the present invention are:

[0016] 1. The conductive base is provided with a through groove for placing two cables at the same time, and the conductive screw plate is slidably assembled on the sliding groove of the conductive base, which not only facilitates the insertion of the cables, but also when the two cables are compressed and locked, only one turn of the conductive screw is required to achieve the connection between the cables.

[0017] 2. By setting a boss on one side of the conductive screw plate, when connecting cables of different diameters, the conductive screw plate can be flexibly installed with the boss facing or facing away from the through slot of the conductive seat, so as to improve the stability of the connection.

[0018] 3. By pre-filling the upper and lower covers with electrical silicone gel, the cable splitter is encased in the gel after the upper and lower covers are closed, achieving internal insulation and waterproofing. Simultaneously, under the action of gravity, some of the gel squeezes out from the gaps between the gel baffles at both ends of the upper and lower covers and the conductors, sealing the gaps and further enhancing waterproofing and moisture-proofing. This solution eliminates the need for on-site injection and avoids the environmental impact of gel leakage. It offers excellent waterproofing and moisture-proofing, a long service life, high safety, easy replacement, and environmentally friendly, simple construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0034] This embodiment relates to a cable connection device with prefabricated gel protection, such as Figure 1 、 2 As shown, it includes: a prefabricated gel waterproof box 1 and a cable brancher 2 assembled in the prefabricated gel waterproof box 1.

[0035] like Figure 3 As shown, the prefabricated gel waterproof box 1 includes: a bottom shell 11, an upper cover 13 and an electric silicone gel 14.

[0036] The upper cover 13 is mounted on the bottom shell 11, and a limiting structure 12 for limiting the position of the cable splitter 2 is provided within the bottom shell 11. A first gel baffle 111 is provided at each end of the bottom shell 11, and a second gel baffle 131 is provided at each end of the upper cover 13 for use with the first gel baffle 111. The first and second gel baffles 111, 131 are used to prevent gel from overflowing. Both the bottom shell 11 and the upper cover 13 are pre-filled with electrical silicone gel 14, a flexible and viscous gel-like substance. When the upper cover 13 and the bottom shell 11 are closed, the electrical silicone gel 14 wraps around the cable splitter 2 under the action of gravity. At the same time, some of the electrical silicone gel 14 squeezes out of the gaps between the gel baffles and the wires, sealing the gaps and achieving waterproof and moisture-proof properties.

[0037] Furthermore, the limiting structure 12 includes a transverse limiting block 121 and a longitudinal limiting block 122 .

[0038] The transverse limiting blocks 121 and the longitudinal limiting blocks 122 include four blocks, which are symmetrically arranged on both sides of the cable connector along the X axis and the Y axis, and respectively limit the transverse and longitudinal directions of the cable connector.

[0039] Further, if Figure 3 、 7 As shown, the limiting structure 12 further includes a positioning hole 123 provided on the bottom shell 11 and located between the longitudinal limiting blocks 122. A positioning pin 211 is provided on the cable connector corresponding to the positioning hole 123, and the cable connector is inserted into the positioning hole 123 through the positioning pin 211 to achieve positioning.

[0040] Furthermore, both the first gel baffle 111 and the second gel baffle 131 are serrated baffles, and the teeth of the serrated baffles are arranged outward.

[0041] like Figure 3 As shown, one side of the upper cover 13 is hinged to one side of the bottom shell 11, and the other side is fastened via a buckle 112. Specifically, the upper cover 13 has multiple buckle holes equidistantly spaced along the length of the side, away from the hinged end. Buckles 112 are provided on the bottom shell 11 corresponding to the buckle holes. The bottom shell 11 fastens the buckle holes 112 to secure the upper cover 13. The ends of the upper cover 13 and bottom shell 11 on the fastening side have corresponding holes b reserved for cable ties, which are used to pass cable ties through these holes to secure the upper cover 13 to the bottom shell 11.

[0042] like Figure 4 As shown, the cable brancher 2 includes an insulating seat 21 and a conductive clamp 22 .

[0043] An insulating base 21 is assembled on the retaining structure 12. The insulating base 21 is provided with at least two mounting grooves c spaced apart from each other. One mounting groove c is perpendicular to another mounting groove c on the insulating base 21. A conductive clip 22 is secured within the mounting grooves c. There are at least two conductive clips 22.

[0044] Preferably, three assembly slots c are equidistantly provided on one side of the insulating base 21, and an assembly slot c is provided on each of the two adjacent sides of the side for placing wires that do not need to be branched, thereby improving the neatness and organization of the entire device. This arrangement can also effectively improve the utilization rate of the base.

[0045] Further, if Figure 5 、 6 As shown, the conductive clamp 22 includes a conductive seat 221 , a conductive screw plate 222 , a conductive screw 223 and a wire pressing plate 224 .

[0046] The conductive seat 221 is arranged in the assembly groove c. The conductive seat 221 is provided with a through groove d for the wire to pass through, and a slide groove a is provided on the inner wall of the through groove d along the axial direction. The conductive screw plate 222 is slidably assembled in the slide groove a. The wire pressing plate 224 is arranged between the conductive screw 223 and the wire. The conductive screw 223 passes through the conductive screw plate 222 to press the wire pressing plate 224 to tighten the wire. Figure 9 、 10 As shown, a boss 2221 is provided on the conductive screw plate 222 . The conductive screw plate 222 can be assembled with the boss 2221 facing toward or away from the through slot d, thereby reducing or increasing the volume of the through slot d to accommodate the placement of wires with different diameters.

[0047] Preferably, the portion of the conductive screw plate 222 installed in the slide groove a is dovetail-shaped, and the slide groove a is also correspondingly provided with a dovetail-shaped groove to adapt to the conductive screw plate 222 and enable the conductive screw plate 222 to be installed on both sides.

[0048] The working principle of the present invention is roughly as follows: Because the power silicone gel 14 is prefabricated within the bottom shell 11 and the upper cover 13, there is no need for on-site pouring, which can effectively prevent the power silicone gel 14 from overflowing, achieving an environmentally friendly and convenient construction effect. During use, the insulation layer at the connecting end of the main cable and the branch cable must be removed to expose the metal conductor. The metal conductors of the main cable and the branch cable are then placed in the same through groove d, and the wire pressure plate 224 is then placed thereon. The conductive screw plate 222 and the conductive screw 223 are then assembled in the slide groove a. By tightening the conductive screw 223, the wire pressure block compresses and locks the metal conductor, thus achieving branching.

[0049] Finally, the cable splitter 2 is partially immersed in the electrical silicone gel 14 and mounted on the retaining structure 12. The first and second gel baffles 111, 131 are cut on either side of the cable and flipped outward to leave space for the cable to pass through. The upper cover 13 is then closed. Gravity forces the electrical silicone gel 14 to envelop the cable connector and metal conductor. Simultaneously, some electrical silicone gel 14 squeezes out of the gaps between the gel baffles and the cable at both ends of the upper cover 13 and the bottom shell 11, sealing the gaps and achieving waterproof and moisture-proof properties, thereby extending the service life. This also avoids issues such as environmental issues caused by gel leakage, operational complications, and lengthy installation times.

[0050] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
