DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-Figure 4 A composite USB low-voltage power line structure shown includes a power line body 100. In order to solve the problem that the metal mesh layer is easy to squeeze the rubber insulation layer, has no good buffering effect, and is easy to be squeezed to cause the rubber insulation layer to be damaged. When the internal rubber insulation layer is damaged, the composite USB low-voltage power line is prone to leakage. In the utility model, the power line body 100 is set to include a core 1, a rubber insulation layer 2, a metal mesh layer 3 and a rubber buffer layer 4. The rubber insulation layer 2 is coated on the outer ring of the core 1. A plurality of rubber buffer layers 4 are provided. The plurality of rubber buffer layers 4 are equidistantly sleeved on the outer ring of the rubber insulation layer 2. The metal mesh layer 3 is coated on the outer ring of the rubber buffer layer 4. A buffer cavity 6 is formed between the plurality of rubber buffer layers 4. The rubber buffer layer 4 and the buffer cavity 6 are effectively formed as a buffer zone between the inner ring of the metal mesh layer 3 and the outer ring of the rubber insulation layer 2. When the metal mesh layer 3 is squeezed, the inner wall of the metal mesh layer 3 is difficult to damage the outer ring of the rubber insulation layer 2, thereby avoiding the problem of leakage of the power line body 100 due to damage of the rubber insulation layer 2.

[0026] The production sequence of the power cord body 100 in the utility model includes:

[0027] First, the rubber insulating layer 2 is coated on the outer ring of the wire core 1, and the rubber insulating layer 2 is fixed on the outer ring of the wire core 1 by using a hot pressing coating process;

[0028] Second, the rubber buffer layer 4 in the utility model has an opening 5, so the rubber buffer layer 4 can be conveniently sleeved on the outer ring of the rubber insulating layer 2 through the opening 5. In actual production, glue or other methods can be used to fix the rubber buffer layer 4 on the outer ring of the rubber insulating layer 2 according to actual needs;

[0029] Third, the metal mesh layer 3 is coated on the outer circle of the rubber buffer layer 4. The metal mesh layer 3 can be fixed on the outer circle of the rubber buffer layer 4 by glue or other methods to complete the production of the power cord body 100.

[0030] The power cord body 100 manufactured by the utility model fully meets the requirements of long service life and low leakage.

[0031] The utility model also discloses an actual use structure of the composite USB low-voltage power line, specifically: three power line bodies 100 are provided, and the three power line bodies 100 are commonly connected to the USB interface 1001, and the ends of the three power line bodies 100 away from the USB interface 1001 are respectively connected to the Android interface, the Apple interface, and the Type C interface; the three charging interfaces can be conveniently connected through one USB interface 1001 to meet the charging needs of different devices.

[0032] There are two types of power cords with three charging interfaces in the prior art:

[0033] The first type: the three power cord bodies 100 are arranged separately, which is convenient for use. However, since the three power cord bodies 100 are long, they are not easy to store, and the three power cord bodies 100 are easy to be entangled with each other.

[0034] The second type: the USB interface 1001 is connected to a bus, and three power cord bodies 100 are connected to the end of the bus far away from the USB interface 1001, and the length of these three power cord bodies 100 is usually between 5-15CM; it is not convenient to use when charging different devices, but it is convenient to store.

[0035] In summary: the power cord with three charging interfaces in the prior art cannot achieve both the convenience of use and the convenience of storage.

[0036] The present invention solves the problem that the prior art cannot take into account both the ease of use and the ease of storage. In the present invention, a sliding sleeve 200 is slidably provided on the three power cord bodies 100, and a plurality of sliding sleeves 200 are provided. Based on the plurality of sliding sleeves 200, it is convenient to slide a plurality of sliding sleeves 200 on the power cord body 100, so as to facilitate control of the length of the three power cord bodies 100 extending out of the sliding sleeve 200, which is convenient for use according to actual needs. When storing, the plurality of sliding sleeves 200 can be slid to different positions on the power cord body 100 at equal distances, so that the three power cord bodies 100 are kept in a long strip state, which is convenient for storage, and the two effects of ease of use and ease of storage are well taken into account.

[0037] The present invention also improves the sliding sleeve 200, solving the problem in the prior art that the sliding sleeve 200 cannot be well positioned on the power cord body 100 after being used for a long time. Specifically, the sliding sleeve 200 includes a sliding shell 2001 and an elastic sleeve 2003. The sliding shell 2001 is a rectangular box structure. The elastic sleeve 2003 is fixedly connected to the inner wall of the sliding shell 2001, and the two ends of the elastic sleeve 2003 respectively move through the two sides of the sliding shell 2001. Three elastic sleeves 2003 are provided; the three power cord bodies 100 respectively move through the three elastic sleeves 2003. Under the elastic covering of the elastic sleeve 2003, the sliding shell 2001 can be well positioned at different positions on the power cord body 100.

[0038] Furthermore, a cleaning cotton sleeve 2004 is fixedly bonded to the inner wall of the elastic sleeve 2003; when the sliding shell 2001 slides along the power cord body 100, the cleaning cotton sleeve 2004 cleans the outer surface of the power cord body 100 and can also maintain the cleanliness of the power cord body 100.

[0039] Furthermore, an air cavity 2002 is formed inside the sliding shell 2001, and a stamping hole 2005 is provided at the bottom of the sliding shell 2001. A detachable seal is provided in the stamping hole 2005 with a plug 2006. By opening the plug 2006, air can be inflated into the air cavity 2002, so that the elastic sleeve 2003 can be more tightly wrapped around the outer ring of the power cord body 100, avoiding the problem of reduced elastic performance of the elastic sleeve 2003 in the later use, and facilitating subsequent adjustment and use.
