Technical Field

[0001] This utility model belongs to the field of HDMI connection cable technology, specifically referring to a waterproof terminal wire harness device for HDMI high-definition connection cables. Background Technology

[0002] HDMI cables are used to transmit high-definition multimedia video signals. HDMI cables can transmit uncompressed high-definition video and multi-channel audio data with high quality and are widely used for high-definition video and audio transmission between electronic devices.

[0003] In outdoor, humid, or harsh environments, traditional HDMI cables lack effective waterproofing at their interfaces, making them susceptible to signal attenuation, short circuits, or equipment damage due to moisture intrusion. Some waterproof connectors use simple tape wrapping, but the sealing effect is unstable and it is difficult to guarantee long-term sealing performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a waterproof terminal harness device for HDMI high-definition connection cables, which effectively solves the problem of unstable sealing and waterproofing effects.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A waterproof terminal wire harness device for HDMI high-definition connection cable includes a male connector and a female connector. The male connector and the female connector are provided with flanges at their end edges. A placement groove is provided at the edge of the flange. A sealing gasket is sealed in the placement groove. The upper and lower sides of the flange are provided with beveled surfaces. A pressing side plate is pressed onto the beveled surface. A pressing plate is fixed on the pressing side plate.

[0006] Preferably, the clamping plates are arranged symmetrically at the top and bottom, and a connecting rod is vertically fixed on one set of clamping plates. The top of the connecting rod is provided with a threaded part, and the threaded part passes through another set of clamping plates and is fastened by a locking nut.

[0007] Preferably, the inclination angle of the extrusion side plate is the same as the inclination angle of the beveled surface, and the extrusion side plate is in close contact with the beveled surface.

[0008] Preferably, the clamping plates are symmetrically arranged plate-shaped structures, and a set of clamping plates are provided with mating holes for the connecting rod to pass through.

[0009] Preferably, the sealing gasket consists of a first retaining ring and a second retaining ring. The first retaining ring has a circular cross-section that fits tightly into the placement groove, and the second retaining ring has a rectangular cross-section and is pressed onto the flange.

[0010] Preferably, the placement groove has a semi-circular cross-section, is arranged around the edge of the flange, and the retaining ring is completely embedded in the placement groove.

[0011] Preferably, the sealing gasket is made of silicone rubber, fluororubber, or nitrile rubber.

[0012] Compared with the prior art, the present invention, by adopting the above-described structure, achieves the following beneficial effects:

[0013] By engaging the locking nut and the threaded part, the beveled surface of the extrusion flange on the extrusion side plate is driven to press the sealing gasket between the male and female heads, preventing the connection from loosening, effectively preventing moisture from entering from the connection, and ensuring the stability of signal transmission.

The utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, the present invention proposes a waterproof terminal harness device for HDMI high-definition connection cables, including a male connector 1 and a female connector 2. Both the male connector 1 and the female connector 2 have flanges 3 at their ends. The flanges 3 have placement grooves 4 at their edges. A sealing gasket 5 is sealed in the placement grooves 4. The flanges 3 have beveled surfaces 6 on their upper and lower sides. A pressing side plate 7 is pressed onto the beveled surface 6. A pressing plate 8 is fixed on the pressing side plate 7.

[0024] like Figure 2 , 3 As shown in Figures 4 and 6, the clamping plates 8 are arranged symmetrically on the top and bottom. A connecting rod 9 is vertically fixed on one set of clamping plates 8. The top of the connecting rod 9 is provided with a threaded part 10. The threaded part 10 passes through another set of clamping plates 8 and is fastened by a locking nut 11, so as to achieve a tight connection between the male head 1 and the female head 2, thereby enhancing mechanical stability and waterproofness. The inclination angle of the extrusion side plate 7 is the same as the inclination angle of the beveled surface 6, and the extrusion side plate 7 is in close contact with the beveled surface 6 to ensure uniform distribution of extrusion pressure, avoid stress concentration, and improve the pressing effect and connection durability of the sealing gasket 5. The clamping plates 8 are symmetrically arranged plate structures, and one set of clamping plates 8 is provided with a mating hole 14 for the connecting rod 9 to pass through, which facilitates installation and disassembly.

[0025] like Figure 2 , 3 As shown, the sealing gasket 5 consists of a first retaining ring 12 and a second retaining ring 13. The first retaining ring 12 has a circular cross-section and fits tightly into the placement groove 4. The second retaining ring 13 has a rectangular cross-section and is pressed onto the flange 3 to increase sealing. The placement groove 4 has a semi-circular arc cross-section and is set around the edge of the flange 3. The first retaining ring 12 is completely embedded in the placement groove 4 to ensure that the sealing gasket 5 is uniformly pressurized circumferentially, preventing moisture from entering from any direction and improving the overall waterproof performance. The sealing gasket 5 is made of silicone rubber, fluororubber, or nitrile rubber, which ensures excellent sealing and resilience while also having resistance to high and low temperatures, aging, and media, significantly improving the service life and reliability of the sealing gasket 5 in complex environments.

[0026] In practical use, during installation, align the male head 1 and female head 2, place the sealing gasket 5 in the placement groove 4 of one of them, and ensure that the retaining ring 12 of the sealing gasket 5 is fully embedded in the placement groove 4, with the retaining ring 12 covering the outer periphery of the flange 3. Tighten the locking nut 11 to move the extrusion side plate 7 along the beveled surface 6, pressing the sealing gasket 5. Press the extrusion side plate 7 onto the beveled surfaces 6 of the male head 1 and female head 2 respectively, ensuring that the connecting rod 9 passes through the mating hole 14. Tighten the locking nut 11 to move the extrusion side plate 7 along the beveled surface 6, bringing the male head 1 and female head 2 closer together to press the sealing gasket 5, completing the installation. Loosen the locking nut 11 in the opposite direction to disassemble the components, facilitating the replacement of the sealing gasket 5 or maintenance.
