Description

Technical Field

[0001] The utility model relates to the technical field of wire interface connection, in particular to a wire sealing and waterproof structure. Background Technique

[0002] A wire is a medium that can stably transmit electric energy. The components of wires are diverse. According to different usage situations, the components and specifications of wires are not the same. And during the production process of wires, a certain length of wire is generally wound into a bundle, and during use, the bundled wire can be straightened. Therefore, the situation where wires need to be truncated often occurs;

[0003] During the connection process of wire interfaces, generally, the insulating layer outside the wire core needs to be peeled off, and then the metal wire cores are wound around each other. At this time, it is necessary for workers to wind and bind with insulating tape to complete the connection between wire interfaces, so as to ensure the sealing performance of the wire interface connection;

[0004] During the winding process with insulating tape, the winding of the insulating glue is generally completed manually. And during the manual winding process, the situation of uneven force on the insulating tape is likely to occur, resulting in wrinkles between the insulating tapes, which easily leads to gaps at the wire interface. And there is a gap between the inner core and the outer skin of the conventional wire, and water vapor can easily enter the relevant charged components through the gap, resulting in a short - circuit situation, reducing the waterproof effect at the existing wire interface connection and affecting the normal connection and use of the wire interface.

[0005] In view of the above problems, it is urgent to innovate on the basis of the original waterproof structure. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] In a specific embodiment, as Figure 1 - Figure 2 shown, the basic working process of this structure is disclosed;

[0029] The first wire 1 and the first inner wire 2 provided inside the first wire 1;

[0030] The first inner wire 2 is provided with a first wire core 3 inside. A conductive circular tube 7 is sleeved outside the first wire core 3, and a second wire core 6 is provided inside one end of the conductive circular tube 7 away from the first wire core 3.

[0031] When using this wire sealing and waterproofing structure, the breakage points of the first wire 1 and the second wire 4 need to be close to each other, and the first inner wire 2 inside the first wire 1 and the second inner wire 5 inside the second wire 4 need to be exposed. At this time, the first inner wire 2 and the second inner wire 5 can be peeled to expose the first core 3 and the second core 6. Then, the conductive circular tube 7 can be sleeved outside the first core 3 and the second core 6 to achieve the initial connection between the first wire 1 and the second wire 4. After that, the metal protective cylinder 9 can be sleeved outside the first wire 1 and the second wire 4 to complete the entire connection process, thereby ensuring the stability and tightness of the connection between the first wire 1 and the second wire 4.

[0032] In one specific embodiment, as Figure 1 - Figure 5 shown, the waterproofing process of this structure is disclosed;

[0033] On the outer side of one end of the second core 6 away from the conductive circular tube 7, there is a second inner wire 5, and on the outer side of one end of the second inner wire 5 away from the second core 6, there is a second wire 4;

[0034] The first inner wire 2 and the first core 3 are arranged at equal angles inside the first wire 1. Both the first inner wire 2 and the first core 3 are made of insulating materials, and the first core 3 is made of conductive metal material. At the same time, the radius of the first core 3 is greater than the thickness of the first inner wire 2;

[0035] The second inner wire 5 and the second core 6 are arranged at equal angles inside the second wire 4. The materials of the second core 6 and the second wire 4 are the same as those of the first inner wire 2 and the first core 3, and the second core 6 and the first core 3 are made of the same material. At the same time, the radius of the second core 6 is greater than the thickness of the second inner wire 5.

[0036] When using this wire sealing and waterproofing structure, after the conductive circular tube 7 is sleeved outside the first core 3 and the second core 6, the conductive circular tube 7 can be extruded. At this time, the conductive circular tube 7 can be deformed, and the conductive circular tube 7 can be in close contact with the first core 3 and the second core 6, improving the firmness of the connection between the first core 3 and the second core 6. And after the metal protective cylinder 9 is installed, the metal protective cylinder 9 also needs to be extruded so that there are extrusion grooves 12 on the outer side of the metal protective cylinder 9, thereby making the connection between the metal protective cylinder 9 and the silicone filling layer 8 closer, improving the sealing effect and stability of the silicone filling layer 8, and ensuring the waterproof effect of the wire interface connection.

[0037] On the basis of the above embodiment, as Figure 1 - Figure 7 shown, the overall waterproof effect of this waterproofing structure is disclosed;

[0038] A silicone filling layer 8 is provided on the outer sides of the first inner wire 2, the second inner wire 5, and the conductive circular tube 7. The silicone filling layer 8 is made of composite silicone material. The two ends of the silicone filling layer 8 are respectively located on the outer sides of the first wire 1 and the second wire 4. At the same time, the conductive circular tube 7 is made of a benign conductive metal material;

[0039] A metal protective cylinder 9 is sleeved on the outer side of the silicone filling layer 8, and extrusion grooves 12 are formed on the outer side of the metal protective cylinder 9; A partition column 10 is nested and installed on the outer side of the conductive circular tube 7, and the partition column 10 is located inside the silicone filling layer 8;

[0040] A sealing groove 11 is formed at the middle position of the conductive circular tube 7, and the sealing groove 11 is located between the first wire core 3 and the second wire core 6.

[0041] After the conductive circular tube 7 is installed, the silicone filling layer 8 can be installed on the outer side of the conductive circular tube 7. The silicone filling layer 8 is formed by installing paste-like silicone on the outer side of the conductive circular tube 7 through a mold. After the paste-like silicone cools, it will solidify into a columnar silicone filling layer 8. At this time, the conductive circular tube 7 can be sealed. During the process of filling the paste-like silicone, the paste-like silicone will enter into the sealing groove 11 and seal the sealing groove 11, ensuring the sealing effect of the connection between the first wire core 3 and the second wire core 6. And the partition column 10 will support and limit the conductive circular tube 7, ensuring that the conductive circular tube 7 is stable during the process of filling the paste-like silicone, thus ensuring the safety during the sealing process, and then ensuring the stability of the installation between the metal protective cylinder 9 and the silicone filling layer 8, avoiding the situation that the first wire 1 and the second wire 4 are separated due to slight external force pulling, and at the same time generally improving the waterproof effect of the wire interface, increasing the overall practicality.
