DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an element centered at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment. The terms "upper end", "lower end", "left side", "right side", "front end", "rear end" and similar expressions used herein are positional relationships with reference to the accompanying drawings.

[0023] In order to make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] See also Figure 1-6 As shown, this embodiment provides a waterproof outdoor display flexible cable. Specifically, it includes a cable body 1 and female connectors 2 mounted at both ends of the cable body 1. The cable body 1 comprises several copper wires 16, which are wrapped in an insulating layer 15. Between the insulating layers 15 is a filler layer 14, which is enclosed in a waterproof sheath 13. The female connector 2 includes a plug connector 4 and a sheath 22. The plug connector 4 is located in the center of the sheath 22. The plug connector 4 is provided with several sockets 3, each containing contact terminals 12 that connect to the copper wires 16. The surface of the sockets 3 is sprayed with a hydrophobic coating. A buffer sleeve 11 is provided between the waterproof sheath 13 and the female connector 2 to prevent wear and bending at the connection. The connection between the female connector 2 and the cable body 1 is waterproofed using TPE injection molding. The sheath 22 is provided with anti-slip grooves 21 for easy insertion and removal. The plug connector 4 is also equipped with a guide post 41 to prevent misalignment with the male terminal 5.

[0025] like Figure 4 、 5 As shown, contact terminal 12 is elastically U-shaped, and its contact surface with male terminal 5 is provided with a barb 121. The insertion end of jack 3 is chamfered 31 for easy automatic alignment and quick insertion. The distance between contact terminal 12 and the insertion end is greater than 1mm, enhancing waterproofing.

[0026] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, its principle is further explained below in combination with the usage method.

[0027] like Figure 3 、 6 As shown, the center of the cable body 1 is the signal line, and the positive and negative poles on both sides of the cable are used for power supply. The cable body 1 and the female connector 2 are connected by TPE injection molding. Figure 4 、 5 As shown, when the female connector 2 is plugged into the male terminal 5, the contact portion 51 of the male terminal 5 is pressed by the elastic contact terminal 12 and hooked by the barb 121, effectively preventing it from loosening. The insulating portion 52 of the male terminal 5 is inserted into the socket 3, achieving waterproofing at the front end and preventing water vapor from entering, and the surface of the socket 3 is sprayed with a hydrophobic layer to further waterproof it. This product can be plugged in water without leakage. First, the socket 3 is internally sealed and has a small aperture. The contact terminal 12 is located inside the socket 3, so water cannot expel the air in the socket 3, resulting in water being unable to enter the socket 3; second, the surface of the socket 3 is sprayed with a hydrophobic layer; third, the male terminal 5 is sealed and connected to the socket 3, and the insulating portion 52 of the male terminal 5 abuts against the entrance of the socket 3, preventing water vapor from entering.

[0028] In summary, the waterproof outdoor display flexible cable provided by this utility model effectively prevents moisture ingress, ensuring stable operation of the outdoor display. By providing a waterproof outer sheath 13 and a protective sheath 22, as well as using TPE injection molding at the connection between the female connector 2 and the cable body 1 and spraying a hydrophobic coating on the surface of the jack 3, the cable's waterproof performance is effectively improved, extending its service life and ensuring stable operation of the outdoor display.
