Description

Technical Field

[0001] This utility model belongs to the field of cable repair, and more specifically, relates to a protective sleeve for a primary intermediate joint of navigation lights. Background Technology

[0002] During the routine maintenance and repair of navigation lights in the field circuit, cable damage and breakage often occur, so it is inevitable to make cable intermediate joints and terminal joints.

[0003] The manufacturing process of intermediate joints for high-voltage cables used for navigation lights can be roughly divided into five steps: cable cleaning, cable stripping, cable crimping, cable encapsulation, and insulation inspection. The process involves many steps and is quite complicated. In the cable crimping step, the exposed cores of the two cables need to be inserted into a copper crimping tube, and then wrapped with insulating tape. Although this can prevent moisture from entering, it cannot guarantee the connection strength of the cables, and the joint is prone to bending and damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective sleeve for a primary intermediate connector of navigation lights. This protective sleeve can reconnect disconnected cables, improve the bending strength of the connection end, and prevent water and moisture damage.

[0005] To achieve the above objectives, this utility model provides a protective sleeve for a primary intermediate connector of a navigation light, comprising:

[0006] A connecting pipe has two ends connected to a first tapered pipe and a second tapered pipe, respectively. The small end of the first tapered pipe is connected to the connecting pipe, and the small end of the second tapered pipe is connected to the connecting pipe.

[0007] A connecting metal pipe is installed inside the connecting pipe, and a partition piece is centrally located inside the connecting metal pipe.

[0008] Optionally, the first tapered tube and the second tapered tube are matched with the shape of the cable insulation layer.

[0009] Optionally, the inner diameter of the connecting metal tube matches the diameter of the copper core of the cable.

[0010] Optionally, the first tapered tube and the second tapered tube are integrally formed with the connecting tube.

[0011] Optionally, the connecting metal tube is centrally located inside the communicating tube.

[0012] Optionally, the outer surface of the connecting metal pipe is provided with a PVC flame-retardant protective sleeve.

[0013] Optionally, the inner circumferential surface of the connecting metal tube is provided with a conductive metal coating.

[0014] Optionally, the length of the insulating tape wrapped around the outer periphery of the first tapered tube and the second tapered tube is the same as the length of the insulating tape on the insulation layer of the cable.

[0015] Optionally, a notch is provided on the outer wall of the connecting metal tube corresponding to the partition piece.

[0016] This utility model provides a protective sleeve for a primary intermediate joint of navigation lights. Its advantages are as follows: the protective sleeve can fix the cable, the connecting metal tube and the partition plate are used to limit the axial displacement of the cable, and the insulation layer of the two tapered tubes is used to limit the radial displacement of the cable, preventing the cable from rotating in the protective sleeve and ensuring the cable's resistance to bending; in addition, the outer periphery of the connecting tube used for connecting the copper core of the cable and the outer periphery of the two tapered tubes are respectively wrapped with insulating tape, and the overlapping part of the two parts is more than half of their respective lengths, so that the insulation effect is good and dustproof and waterproof effects can be achieved.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0023] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0024] This utility model provides a protective sleeve for a primary intermediate connector of a navigation light, comprising:

[0025] The connecting tube is connected at both ends to the first tapered tube and the second tapered tube respectively. The small end of the first tapered tube is connected to the connecting tube, and the small end of the second tapered tube is connected to the connecting tube.

[0026] A connecting metal pipe is installed inside the connecting pipe, and a partition plate is installed in the center of the inside of the connecting metal pipe.

[0027] Specifically, the protective sleeve includes an outer connecting tube, two tapered tubes, and an inner connecting metal tube. The two tapered tubes match the profile of the cable's insulation layer. Once the cable is inserted into the tapered tube, the radial position of the cable can be limited. Then, the connecting metal tube is inserted into the copper core of the cable. The insertion length of the cable can be limited by the partition plate to ensure the accuracy of the axial position of the cable. In this way, the connection stability of the two disconnected cable segments can be guaranteed. The protection of the tapered tube and the connecting tube can improve the bending strength of the connection.

[0028] In one embodiment, the first tapered tube and the second tapered tube can be of the same size, or one large and one small, with the size of the corresponding tapered tube selected according to the size of the insulation layer of the disconnected cable.

[0029] Optionally, the first tapered tube and the second tapered tube are matched with the shape of the cable insulation layer.

[0030] Optionally, the inner diameter of the connecting metal tube matches the diameter of the copper core of the cable.

[0031] Specifically, before inserting the two disconnected cable segments into the protective sleeve, the cables need to be processed. The insulation layer of the cable is stripped to expose copper cores of equal length. Then, the insulation layer near the copper core end is tapered. This prevents the cable from rotating when inserted into the tapered tube. When the copper core of the cable is inserted into the connecting metal tube, it will not continue to be inserted into the connecting metal tube after contacting the partition. This ensures that the copper cores of both cable segments are inserted into the connecting metal tube, allowing the disconnected cable to be reconnected.

[0032] Optionally, the first tapered tube and the second tapered tube are integrally formed with the connecting tube.

[0033] Optionally, the connecting metal pipe is centrally located inside the connecting pipe.

[0034] Specifically, the tapered tube and the connecting tube are designed as a single unit, and then the connecting metal tube is fixed inside the connecting tube. This way, when disconnecting the cable connection, it is only necessary to insert the cable into place, without having to confirm the insertion length or perform any extra operations. Simply press the connecting metal tube into contact with the internal copper core, and the whole operation is simple.

[0035] Optionally, a PVC flame-retardant protective sleeve is provided on the outer surface of the connecting metal pipe.

[0036] Optionally, the inner circumferential surface of the connecting metal tube is provided with a conductive metal coating.

[0037] Specifically, the flame-retardant sleeve on the outer surface of the connecting metal tube can prevent moisture and flame, thus isolating the copper core of the cable from the external environment; a conductive layer is set inside the connecting metal tube. When the copper core of the cable is inserted into the connecting metal tube, as long as the connecting metal tube is squeezed and deformed, so that the conductive layer comes into contact with the copper core, the disconnected cable can be reconnected.

[0038] Optionally, the length of the insulating tape wrapped around the outer periphery of the first and second tapered tubes is the same as the length of the insulating tape on the insulation layer of the cable.

[0039] Specifically, after inserting the two cable sections into the protective sleeve, the connecting metal tube is clamped to make it contact the internal copper core, and finally, insulating tape is wrapped around the outer perimeter of the protective sleeve. First, insulating tape is wrapped around the outer perimeter of the connecting tube, and then insulating tape is wrapped around the two tapered tubes respectively, so that the insulating tape at both ends and the insulating tape in the middle section overlap each other, forming a continuous protective barrier around the outer perimeter of the protective sleeve, which can prevent water splashes and dust.

[0040] Optionally, a notch is provided on the outer wall corresponding to the connecting metal tube and the partition piece.

[0041] Specifically, after the copper core of the cable is inserted into the connecting metal tube, pliers are used to clamp the connecting tube and a notch is set on the connecting metal tube. This way, when the connecting metal tube is squeezed and deformed, the surface of the tube will not deform or break. While ensuring the internal cable of the connecting metal tube is connected, it is also necessary to ensure the integrity of the insulation and flame-retardant barrier on the outside of the connecting metal tube.

[0042] Example

[0043] like Figures 1 to 2 As shown, this utility model provides a protective sleeve for a primary intermediate connector of a navigation light, comprising:

[0044] The connecting pipe 1 is connected to the first conical pipe 2 and the second conical pipe 3 at both ends respectively. The small end of the first conical pipe 2 is connected to the connecting pipe 1, and the small end of the second conical pipe 3 is connected to the connecting pipe 1. The large ends of the first conical pipe 2 and the second conical pipe 3 are respectively provided with a first round pipe 4 and a second round pipe 5.

[0045] A connecting metal pipe 6 is installed in the connecting pipe 1, and a partition piece 7 is installed in the center of the inside of the connecting metal pipe 6.

[0046] In this embodiment, the first tapered tube 2 and the second tapered tube 3 are matched with the shape of the cable insulation layer 8.

[0047] In this embodiment, the inner diameter of the connecting metal tube 6 matches the diameter of the copper core 9 of the cable.

[0048] In this embodiment, the first circular tube 4, the second circular tube 5, the first tapered tube 2, the second tapered tube 3, and the connecting tube 1 are integrally formed.

[0049] In this embodiment, the connecting metal pipe 6 is centrally located inside the connecting pipe 1.

[0050] In this embodiment, a PVC flame-retardant protective sleeve is provided on the outer surface of the connecting metal pipe 6.

[0051] In this embodiment, a conductive metal coating is provided on the inner circumferential surface of the connecting metal tube 6.

[0052] In this embodiment, the length of the insulating tape wrapped around the outer periphery of the first tapered tube 2 and the second tapered tube 3 is the same as the length of the insulating tape on the insulation layer of the cable.

[0053] In this embodiment, a notch is provided on the outer wall corresponding to the metal tube 6 and the partition piece 7.

[0054] In summary, before using this protective sleeve, the insulation layers of the two disconnected cable sections are first cut open to a certain length. Then, the insulation layer near the copper core is shaped into a cone to make the transition section between the copper core and the insulation layer relatively smooth. Then, a protective sleeve of the corresponding size is selected, and the two cable sections are inserted into the first cone-shaped tube 2 and the second cone-shaped tube 3 respectively. At the same time, the copper core 9 is inserted into the connecting metal tube 6 and abuts against the partition plate 7. In this way, both cable sections are installed in place. Then, pliers are used to squeeze the connecting tube so that the inner wall of the connecting metal tube 6 contacts the copper core 9, thus realizing the connection of the disconnected cables. Finally, insulating tape is wrapped around the connecting tube 1 and the cone-shaped tube 2 of the protective sleeve to improve the dustproof and waterproof effect at the connection.

[0055] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
