Problems solved by technology

Two USB ports and one HDMI port are generally installed on the existing digital TV, so in order to realize the normal operation of the digital TV, the digital TV needs to be connected with three wires, that is, two USB wires and one HDMI wire, but the three wires will It takes up a lot of space. In addition, the three wires will make the wiring on the back of the digital TV messy, which is not conducive to the appearance of the digital TV.

Embodiment 1

[0037] like Figure 1 to Figure 6 As shown, this embodiment discloses an HDMI and USB integrated connecting cable, including a wire 10 and two interfaces 20 located at both ends of the wire 10; the interface 20 includes a cable clip 21 with a rear end and a front end, and a cable clip 21 The PCB board 22 at the front end, the plug 23 connecting the PCB board 22, and the shell 24 covering the part of the cable clip 21, the PCB board 22 and the plug 23;

[0038] The wire 10 includes a first insulating layer 11 and an HDMI cable 13 and two USB cables 12 located in the first insulating layer 11; each USB cable 12 includes a first shielding layer 121 and a first signal line 122 located in the first shielding layer 121 and the first ground wire 123; every two first signal wires 122 and a first ground wire 123 in the first shielding layer 121 are covered by a second shielding layer 124; the HDIM line includes a third shielding layer 131 and is located at the second shielding layer T...

Embodiment 2

[0057] like Figure 7 and Figure 8 As shown, the difference between the second embodiment and the first embodiment is that: a clamping elastic piece 32 is provided in the insertion cavity 31 . The setting of the clamping elastic piece 32 enables the plug 23 to be clamped by the clamping elastic piece 32 , which strengthens the connection between the plug 23 and the dustproof cover 30 .

[0058] Two sides of the dustproof cover 30 are provided with pushing protrusions 33 . By setting the pushing protrusion 33 on the dustproof cover 30 , it is convenient for people to apply force on it, which has the beneficial effect of quickly and labor-savingly separating the dustproof cover 30 from the plug 23 .

[0059] One end of a dustproof cover 30 away from the wire rod 10 is provided with a cover clamping protrusion 34, and the other end of the dustproof cover 30 away from the wire rod 10 is provided with a cover clamping groove 35, so that the two dustproof covers 30 can be clamped...

Abstract

The invention discloses a combined connecting line for an HDMI and a USB and a fabrication technology of the combined connecting line. The combined connecting line for the HDMI and the USB comprises a line material and two ports, wherein the two ports are connected with the line material; each port comprises a traverse clamp, a PCB, a plug and a housing; each PCB is connected to the front end of the corresponding traverse clamp; each plug is connected with the corresponding PCB; each housing coats the corresponding traverse clamp, PCB and partial plug; the line material is connected to the PCBs; the line material comprises a first insulating layer, an HDMI line and two USB lines; the HDMI line and the two USB lines are located in the first insulating layer; each USB line comprises a first shielding layer, first signal lines and first ground lines; the first signal lines and the first ground lines are located in the corresponding first shielding layer; every two first signal lines and one first ground line in each first shielding layer are coated through a second shielding layer; the HDIM line comprises a third shielding layer, second signal lines and second ground lines; the second signal lines and the second ground lines are located in the corresponding third shielding layer; every two second signal lines and one second ground line in each third shielding layer are coated through a fourth shielding layer; and the HDMI line and the two USB lines are electrically connected with the PCBs respectively. According to the combined connecting line for the HDMI and the USB, the HDMI line and the two USB lines can be combined into a whole, so that the occupied space of the HDMI line and the two USB lines is reduced.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to an HDMI and USB combined connection wire. Background technique [0002] Digital TV, also known as digital TV or digital TV, means that all links from the studio to launch, transmission, and reception use digital TV signals or all signal transmissions for the system are composed of 0 and 1 digital strings The type of television that broadcasts a stream of binary numbers. Compared with analog TV, its signal loss is small and the reception effect is good. Two USB ports and one HDMI port are generally installed on the existing digital TV, so in order to realize the normal operation of the digital TV, the digital TV needs to be connected with three wires, that is, two USB wires and one HDMI wire, but the three wires will It takes up a lot of space. In addition, the three wires will make the wiring on the back of the digital TV messy, which is not conducive to the appearance of the dig...
