Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber joint tension resistance, in particular to a tension-resistant HDMI optical fiber joint connecting line. Background Art

[0002] With the rapid popularization of high-definition multimedia, or HDMI interface, devices with HDMI interface have begun to be widely used in various scenarios. In engineering application scenarios, during the wiring process of HDMI optical fiber connectors with a length of 20 meters or more, the fiber core and electronic wire in the internal structure of the optoelectronic composite cable bear the pulling force, so it is easy to break the fiber core of the HDMI optoelectronic composite cable.

[0003] After searching, the Chinese patent application number 202221960278.X discloses a tensile-resistant HDMI fiber optic connector cable, including a high-definition multimedia connector and a fiber optic hybrid cable. The fiber optic hybrid cable is provided with a fiber core, an electronic wire and an anti-tensile wire. The high-definition multimedia connector includes a protective shell, and an HDMI optoelectronic module is provided in the protective shell. The upper end of the HDMI optoelectronic module is connected to an HDMI plug extending out of the protective shell. The fiber optic hybrid cable extends into the lower end of the protective shell, and the fiber core and the electronic wire are respectively connected to the HDMI optoelectronic module. An upper steel sheet for the anti-tensile wire to bypass is provided in the protective shell, and a lower steel sheet for fixing the free ends of the fiber optic hybrid cable and the anti-tensile wire in the protective shell is provided in the protective shell. When the high-definition multimedia connector is pulled, the anti-tensile wire is pulled through the protective shell of the high-definition multimedia connector, and the upper steel sheet, the lower steel sheet and the anti-tensile wire cooperate to withstand the pulling force of the wire, thereby protecting the fiber core and the electronic wire from being broken.

[0004] The above patent has the following deficiencies: 1. After the optical fiber hybrid cable is fixed by the upper steel plate and the lower steel plate, when tension is applied, the connection between the upper steel plate and the lower steel plate and the optical fiber hybrid cable lacks elasticity, making it difficult to effectively absorb the tension, which may cause the optical fiber hybrid cable to break and is not convenient for extending its service life; 2. In actual applications, due to the needs of different usage scenarios, the plug needs to be rotated to different angles, which can easily cause the optical fiber hybrid cable to twist. Long-term twisting may cause unstable connection of the internal line, affecting its normal function.

[0005] The device therefore urgently needs a tensile-resistant HDMI optical fiber connector cable to solve the above problems. Utility Model Content

[0027] like Figure 1-4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the buffer assembly includes a relief plate 110 slidably connected to the top wall of the upper steel plate 107 through a groove group 108, and the side wall of the relief plate 110 is slidably connected with evenly distributed pull ropes 111, and the inner wall of the groove group 108 is fixedly connected with a tension spring 112. The pull rope 111 can prevent the hybrid cable 109 from sliding out of the upper steel plate 107 and the lower steel plate 105, thereby improving the stability of the hybrid cable 109 after installation.

[0028] like Figure 1-5As shown, as a preferred embodiment, on the basis of the above method, further, the end of the tension spring 112 away from the pull groove is also fixedly connected to the relief plate 110, and the end of the pull rope 111 away from the relief plate 110 is also fixedly connected to the lower steel plate 105. The tension can be absorbed by the action of the tension spring 112, thereby preventing the hybrid cable 109 from being broken, which is more practical.

[0031] Specifically, when using this tensile-resistant HDMI fiber optic connector cable: first remove the upper shell 131, then place the connection of the hybrid cable 109 on the lower steel plate 105, and then tighten the first bolt 106 to drive the upper steel plate 107 to squeeze the hybrid cable 109, thereby fixing the hybrid cable 109, and then slide the three sets of pull ropes 111 from one side of the relief plate 110 to a position in contact with the hybrid cable 109, and under the action of the tension spring 112, the pull ropes 111 apply tension to the hybrid cable 109, thereby further improving the stability of the hybrid cable 109 after installation. After the installation is completed, the threaded rods 123 on both sides are rotated at the same time to drive the installation. The mounting plate 103 slides so that the fiber core 130 is not in a tensioned state. At the same time, the clamping plate 122 is installed on the top of the clamping frame 120 through the second bolt 121, thereby further improving the stability of the fiber core 130 and preventing the occurrence of unstable connection. After the installation is completed, the upper shell 131 is installed. When the angle of the plug 101 needs to be deflected during use, the connecting piece 104 can be rotated so that the hybrid cable 109 is not in a twisted state. At the same time, when the hybrid cable 109 is pulled, the pulling force can be absorbed by the action of the tension spring 112 and the spring 124, thereby reducing the risk of the hybrid cable 109 being broken, which is convenient for increasing the service life of the hybrid cable 109.
