Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, and in particular to a lighting cable with a water-blocking device. Background Technology
[0002] With the development of industrial technology, cables are increasingly widely used in various fields, especially in lighting, where they are used to connect lighting fixtures. The requirements for cables in the lighting field are relatively lower than those in the communications field. Please refer to [link / reference needed]. Figure 1 Typical lighting cables consist of multiple insulated cores 101 and an outer sheath 102. This is especially true for cables used in outdoor tunnel lights, floodlights, and landscape lights. When connecting to the lighting fixture's controller or other wiring, wires are soldered, and after connection, the cable is wrapped with electrical tape or other protective material. However, due to rain exposure, cable twisting, or other reasons, the outer sheath 102 may break, allowing water to seep between the insulated cores 101 and the outer sheath 102. This water then flows through the gaps between the insulated cores 101 and the outer sheath 102 into the solder joints of the lighting fixture and into the fixture itself, posing a risk of short circuits or electrical leakage. Therefore, there is a need for a lighting cable with a water-blocking device to avoid these risks. Utility Model Content

[0004] A lighting cable with a water-blocking device includes a first silicone wire, a second silicone wire, an adapter plate, a water-blocking structure, and an outer sleeve. The second silicone wire is connected to a lighting device. The first silicone wire includes a plurality of first insulated cores and a first sheath wrapping around the plurality of first insulated cores. The second silicone wire includes a plurality of second insulated cores and a second sheath wrapping around the plurality of second insulated cores.

[0006] In one embodiment, the water-blocking structure is molded to encapsulate the adapter plate, the first insulated wire core connected to the adapter plate, the second insulated wire core, and portions of the first and second sheaths near the adapter plate. A portion of the water-blocking structure is embedded in the gaps between the first and second insulated wire cores. In this configuration, the water-blocking structure partially encapsulates the first and second sheaths, resulting in better overall integrity between the water-blocking structure and the first and second silicone wires.
[0007] In one embodiment, the first silicone wire includes two first insulated wire cores, and the second silicone wire includes two second insulated wire cores, wherein the diameter of the first insulated wire cores is the same as the diameter of the second insulated wire cores.

[0009] In one embodiment, the water-blocking structure is cylindrical in shape, the outer sleeve is cylindrical in shape, and the inner diameter of the outer sleeve and the outer diameter of the water-blocking structure are fitted with a clearance.
[0010] In one embodiment, the water-blocking structure is made of silicone.
[0011] In one embodiment, the outer sleeve is made of aluminum.
[0012] In one embodiment, the wall thickness of the outer sleeve is 0.3-1 mm.
[0013] In one embodiment, the outer diameter of the water-blocking structure is the same as the outer diameter of the first sheath and the outer diameter of the second sheath.
[0014] The beneficial effects of this utility model are as follows: By adding an adapter plate and a water-blocking structure between the first silicone wire and the second silicone wire, the adapter plate connects the first silicone wire and the second silicone wire, and the water-blocking structure seals the connection between the adapter plate, the first silicone wire and the second silicone wire through hydraulic integral molding, blocking the water in the gap between the first insulated core and the first sheath in the first silicone wire, preventing water from flowing into the second silicone wire, and thus protecting the lighting fixture; the outer tube sleeve is fitted on the water-blocking structure to reinforce the water-blocking structure, which is both aesthetically pleasing and ensures that the water-blocking structure presses tightly against the first silicone wire and the second silicone wire, achieving a waterproof effect.

[0025] Example
[0026] Please see Figure 2 and Figure 3 This utility model provides a lighting cable 100 with a water-blocking device, including a first silicone wire 1, a second silicone wire 2, an adapter plate 3, a water-blocking structure 4, and an outer sleeve 5. The second silicone wire 2 is connected to a lighting device (not shown in the figure), wherein the lighting device is mainly an LED light strip, tunnel light, etc. The first silicone wire 1 includes a plurality of first insulated wire cores 11 and a first sheath 12 that wraps the plurality of first insulated wire cores 11. The second silicone wire 2 includes a plurality of second insulated wire cores 21 and a second sheath 22 that wraps the plurality of second insulated wire cores 21. The plurality of first insulated wire cores 11 are connected to one end of the adapter plate 3, and the plurality of second insulated wire cores 21 are connected to the other end of the adapter plate 3. The water-blocking structure 4 is molded to wrap the adapter plate 3 and the first insulated wire cores 11 and second insulated wire cores 21 connected to the adapter plate 3. The water-blocking structure 4 blocks water at the gap between the plurality of first insulated wire cores 11 and the first sheath 12. The outer sleeve 5 is fitted on the water-blocking structure 4. Preferably, the water-blocking structure 4 is integrally molded to wrap the adapter plate 3 and the first insulated wire core 11 and the second insulated wire core 21 connected to the adapter plate 3. It is understood that the longer the first silicone wire 1, the greater the probability of sheath damage due to twisting or other reasons. The water-blocking structure 4 is located near the second silicone wire 2 of the LED light strip, tunnel light and other lighting fixtures. That is, the closer the water-blocking structure 4 is to the LED light strip, tunnel light and other lighting fixtures, the better the water-blocking effect.
[0027] For more details, please refer to Figure 2 The water-blocking structure 4 is molded to wrap the adapter plate 3, the first insulated wire core 11, the second insulated wire core 21 connected to the adapter plate 3, and a portion of the first sheath 12 and the second sheath 22 near the adapter plate 3. A portion of the water-blocking structure 4 is embedded in the gaps between the first insulated wire cores 11 and the gaps between the second insulated wire cores 21. In another embodiment of this invention, the water-blocking structure 4 is molded to wrap the adapter plate 3, the first insulated wire core 11, the second insulated wire core 21, and the second sheath 22 connected to the adapter plate 3, and abuts against a portion of the first sheath 12 near the adapter plate 3. Compared to the previous embodiment, this arrangement can block water from flowing into the gap between the first insulated wire core 11 and the first sheath 12; however, the connection effect between the end face of the water-blocking structure 4 and the first sheath 12 is not ideal.
[0028] For more details, please refer to Figure 2 and Figure 3The first silicone wire 1 includes five first insulated wire cores 11 of different diameters, and the second silicone wire 2 includes five second insulated wire cores 21 of different diameters. It is understood that this utility model uses two different specifications and quantities of first insulated wire cores 11 and second insulated wire cores 21 for description, aiming to illustrate that there are gaps between the different numbers of first insulated wire cores 11 and the first sheath 12, and gaps between the second insulated wire cores 21 and the second sheath 22. The water-blocking structure 4 seals the gaps between the first insulated wire cores 11 and the first sheath 12, as well as the gaps between the second insulated wire cores 21 and the second sheath 22, thereby preventing water from flowing into the gap between the first insulated wire cores 11 and the first sheath 12 and then into the gap between the second insulated wire cores 21 and the second sheath 22, thus preventing the lighting device from burning out.
[0029] In another embodiment of this invention, the first silicone wire 1 includes two first insulated wire cores 11, and the second silicone wire 2 includes two second insulated wire cores 21. The diameter of the first insulated wire core 11 is the same as the diameter of the second insulated wire core 21.
[0030] For more details, please refer to Figure 2 and Figure 3 , Figure 3 The diagram shows an exploded view of the lighting cable. The water-blocking structure 4 is cylindrical, as is the outer sleeve 5. The inner diameter of the outer sleeve 5 and the outer diameter of the water-blocking structure 4 are fitted with a clearance. The cylindrical water-blocking structure 4 is shown in two halves, but this does not mean that the water-blocking structure 4 is a separate structure. It is only used to describe the wrapping structure. The water-blocking structure 4 is still a single cylindrical structure made by hydroforming, which wraps the adapter plate 3, the first insulated wire core 11 connected to the adapter plate 3, the second insulated wire core 21, and the first sheath 12 and the second sheath 22 near the adapter plate 3.
[0031] The water-blocking structure 4 is made of silicone, preferably liquid silicone. The outer sleeve 5 is made of aluminum, with a wall thickness of 0.3-1mm, preferably 0.5mm. The thin aluminum outer sleeve 5 is fitted onto the water-blocking structure 4, which not only reinforces the water-blocking structure 4 but also ensures that the water-blocking structure 4 presses tightly against the first silicone line 1 and the second silicone line 2, while also achieving an excellent appearance.
[0032] This invention adds an adapter plate 3 and a water-blocking structure 4 between the first silicone wire 1 and the second silicone wire 2. The adapter plate 3 connects the first silicone wire 1 and the second silicone wire 2. The water-blocking structure 4 is hydraulically integrally formed to seal the connection between the adapter plate 3, the first silicone wire 1, and the second silicone wire 2, blocking water from flowing into the second silicone wire 2 through the gap between the first insulated core 11 and the first sheath 12 in the first silicone wire 1, thus protecting the lighting fixture. The outer sleeve 5 is fitted onto the water-blocking structure 4 to reinforce the water-blocking structure 4, which is both aesthetically pleasing and ensures that the water-blocking structure 4 presses tightly against the first silicone wire 1 and the second silicone wire 2, achieving a waterproof effect.
[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
