[0002] Waterproof protection of cable joints refers to a series of measures taken at the cable connection points to prevent moisture and humidity from entering the cable, thereby avoiding electrical faults or performance degradation caused by moisture intrusion.

[0003] Chinese Patent Publication No. CN212063452U, published on December 1, 2020, discloses a cable connector. The cable connector includes a main body, an annular first end cap, and an annular second end cap. The first end cap is installed at a first end of the main body, and the second end cap is installed at a second end of the main body. The main body has a first tapered surface on its inner wall near the first end, with the larger end of the tapered surface facing the first end of the main body. The cable connector also includes a first sealing ring, the outer wall of which abuts against the first tapered surface. The inner wall of the first end cap has a first push cylinder for abutting against one side of the first sealing ring. The first push cylinder is coaxially arranged with the first end cap and protrudes from one side of the first end cap.

[0004] In demagnetization operations, multiple cables are often used to ensure the entire hull is covered to protect various types of ships. However, after the cable joints are connected, they are often simply wrapped with insulating tape. The cable joints are prone to corrosion due to contact with seawater, which affects the conduction efficiency and heat dissipation. Moreover, in order to remove rust, a long grinding process is required before each operation. Therefore, there is an urgent need to propose a corresponding waterproof protection device for cable joints to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof protection device for cable joints in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof protection device for cable joints includes two sets of mounting sleeves, which are respectively fixedly connected to two cable segments. Each set of mounting sleeves has an outer ring and a locking component for locking the position of the outer ring integrated on its outer side. A central housing is detachably connected between the two sets of outer rings, and honeycomb protrusions are fixedly connected to the outer wall of the arc-shaped end of the central housing.

[0008] Preferably, multiple sets of protrusions are fixedly connected to the inner surface of the arc-shaped end of the middle shell, and the multiple sets of protrusions are distributed in a ring.

[0009] Preferably, the locking assembly includes a connecting ring fixedly connected to the outer wall of the outer ring, the connecting ring being sleeved on the outside of the mounting sleeve, and a locking sleeve being screwed onto the outer wall of the connecting ring through a threaded groove, wherein the inner wall of the vertical end of the locking sleeve abuts against the connecting ring and the outer wall of the mounting sleeve.

[0010] Preferably, a mating ring is fixedly connected to the side of the outer ring away from the connecting ring, and steps are provided on the inner surface walls of both sides of the horizontal end of the middle shell, and a threaded groove is provided on the step to engage with the mating ring.

[0011] Preferably, a sealing gasket is fixedly connected to the inner wall of the vertical end of the locking sleeve, and the sealing gasket abuts against the connecting ring and the outer wall of the mounting sleeve.

[0012] Preferably, sealing gaskets are fixedly connected to both sides of the horizontal end of the outer ring.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, two sets of mounting sleeves are fixed to two segmented cables respectively. After the two sets of outer rings are fixed to both sides of the middle housing, the middle housing is moved to place it outside the cable connection point after the two sets of cables are connected. The connecting ring on the outside of the outer ring overlaps the outside of the mounting sleeve. Finally, the locking sleeve is screwed into the connecting ring through the second threaded groove to fix the middle housing. The sealing gasket on the inner surface of the vertical end of the locking sleeve ensures the airtightness between the locking sleeve, the mounting sleeve and the connecting ring. The two sets of sealing gaskets on both sides of the outer ring ensure the airtightness between the locking sleeve, the outer ring and the middle housing.

[0015] 2. In this application, the outer part of the middle shell has a honeycomb-like raised structure, which can effectively improve the heat dissipation efficiency at the cable connection. The inner part has a TPU soft structure of raised sheets, which can reduce the air volume. Moreover, since the raised sheets will contact the exposed cable joint, the heat transfer efficiency will be further increased, so as to ensure that the heat dissipation efficiency at the entire joint is increased.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] The cable joint waterproof protection device includes two sets of mounting sleeves 7, which are fixedly connected to two cable segments respectively. Both sets of mounting sleeves 7 have an outer ring 3 integrated on their outer sides and a locking component for locking the position of the outer ring 3. A middle housing 1 is detachably connected between the two sets of outer rings 3, and a honeycomb protrusion 2 is fixedly connected to the outer wall of the arc-shaped end of the middle housing 1.

[0025] Two sets of mounting sleeves 7 are fixed to two segmented cables respectively. After the two sets of mating rings 5 ​​are fixed to both sides of the middle housing 1, the middle housing 1 is moved to the outside of the cable connection point after the two sets of cables are connected. The connecting ring 6 on the outside of the outer ring 3 overlaps the outside of the mounting sleeve 7. Finally, the locking sleeve 4 is screwed into the connecting ring 6 through the threaded groove 12 to fix the middle housing 1. The sealing gasket 8 on the inner surface of the vertical end of the locking sleeve 4 ensures the airtightness between the locking sleeve 4, the mounting sleeve 7 and the connecting ring 6. The two sets of sealing gaskets on both sides of the outer ring 3 ensure the airtightness between the locking sleeve 4, the outer ring 3 and the middle housing 1.

[0026] Multiple sets of protrusions 9 are fixedly connected to the inner surface of the arc-shaped end of the middle shell 1, and the multiple sets of protrusions 9 are distributed in a ring.

[0027] The outer part of the middle shell 1 has a honeycomb-like protrusion structure 2, which can effectively improve the heat dissipation efficiency at the cable connection. The inner part has a TPU soft structure protrusion 9, which can reduce the air volume. Moreover, since the protrusion 9 will contact the exposed cable joint, the heat transfer efficiency will be further increased, so as to ensure that the heat dissipation efficiency at the entire joint is increased.

[0028] It should be noted that the preferred combination of the mounting sleeve 7, outer ring 3, connecting ring 6, mating ring 5 and locking sleeve 4 is an existing cable connector made primarily of nylon PA66.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, the locking assembly includes a connecting ring 6 fixedly connected to the outer wall of the outer ring 3. The connecting ring 6 is sleeved on the outside of the mounting sleeve 7. The outer wall of the connecting ring 6 is screwed with a locking sleeve 4 through a threaded groove 12. The inner wall of the vertical end of the locking sleeve 4 abuts against the connecting ring 6 and the outer wall of the mounting sleeve 7. This ensures that the outer ring 3 and the middle housing 1 can be easily disassembled and assembled, while the middle housing 1 and the outer ring 3 can be horizontally misaligned to facilitate the operation at the joint connection. A mating ring 5 is fixedly connected to the side of the outer ring 3 away from the connecting ring 6. Steps 10 are provided on the inner walls of both sides of the horizontal end of the middle housing 1, and threaded grooves 11 are provided on the steps 10 to be screwed with the mating ring 5. This conforms to the structural features of the cable joint and ensures the ease of independent disassembly and assembly of the middle housing 1.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, a sealing gasket 8 is fixedly connected to the inner surface of the vertical end of the locking sleeve 4. The sealing gasket 8 abuts against the outer surface of the connecting ring 6 and the mounting sleeve 7. Sealing gaskets 2 are fixedly connected to both sides of the horizontal end of the outer ring 3. The sealing gasket 8 on the inner surface of the vertical end of the locking sleeve 4 ensures the airtightness between the locking sleeve 4, the mounting sleeve 7 and the connecting ring 6. The two sets of sealing gaskets 2 on both sides of the outer ring 3 ensure the airtightness between the locking sleeve 4, the outer ring 3 and the middle housing 1.

[0031] Working principle: Two sets of mounting sleeves 7 are fixed to two segmented cables respectively. Two sets of mating rings 5 ​​are fixed to both sides of the central housing 1. At this time, the central housing 1 needs to be pre-fitted onto the outside of the cables, and the locking sleeve 4 also needs to be fitted onto the outside of the cables 1 simultaneously. After the two sets of cables are connected, the central housing 1 is moved to the outside of the cable connection point. The connecting ring 6 on the outside of the outer ring 3 overlaps with the outside of the mounting sleeve 7. Finally, the locking sleeve 4 engages with the connecting ring 6 through the threaded groove 12. When the threaded connection is completed by the locking sleeve 4, the connecting ring 6 and the mounting sleeve 7 are compressed by the locking sleeve 4, allowing the mounting sleeve 7 to seal both ends of the cable connection, improving the sealing performance of the connection. This achieves the fixation of the middle housing 1. The sealing gasket 8 on the inner surface of the vertical end of the locking sleeve 4 ensures the airtightness between the locking sleeve 4, the mounting sleeve 7, and the connecting ring 6. The two sets of sealing gaskets on both sides of the outer ring 3 ensure the airtightness between the locking sleeve 4, the outer ring 3, and the middle housing 1. The outer side of the middle housing 1 has a honeycomb-like protrusion 2 structure, which can effectively improve the heat dissipation efficiency at the cable connection. The inner side has TPU soft structure protrusions 9, which can reduce the volume of air. Moreover, since the protrusions 9 will contact the exposed cable joint, multiple sets of protrusions 9 can make good contact with the cable and transfer heat to the protrusions 9 in time, further increasing the heat transfer efficiency and ensuring that the heat dissipation efficiency at the entire joint is increased.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
