Description

Technical Field

[0001] The utility model relates to the technical field of HDMI cable joints, in particular to a HDMI cable rotary joint. Background Art

[0002] HDMI data cable is a cable used to transmit high-definition multimedia video signals. HDMI data cable can transmit uncompressed high-definition video and multi-channel audio data with high quality, with a maximum data transmission speed of 5Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality audio and video signal transmission. HDMI data cable includes two HDMI connectors and a data cable connected between the HDMI connectors.

[0003] At present, the HDMI cables on the market are mainly used for connecting DVDs, computer hosts and monitors, high-definition televisions or projection equipment. However, the output interfaces of DVDs and computer hosts or the input interfaces of monitors, high-definition televisions and projection equipment of different manufacturers and brands are set in different directions. The HDMI cable connector in the prior art includes a connector body, a connecting cable is installed at the rear end of the connector body, and a plug is fixed at the front end of the connector body. When the above HDMI cable connector is used, long-term use will cause the wire of the HDMI cable to bend and deform, resulting in poor HDMI wire material, and it is not easy to disassemble. Usually, if one component is damaged, all components must be replaced, which is inconvenient to use.

[0004] Therefore, the prior art needs to be improved and enhanced. Utility Model Content

[0033] Example:

[0034] like Figure 1-4 The present application discloses a HDMI cable rotary connector, comprising a connector body 100, a plug 200 disposed at one end of the connector body 100, a screw-on component 300 disposed at the other end of the connector body 100 and rotatably engaged with the connector body 100, and a connecting wire 400 connected to the screw-on component 300. Through the above structural design, the connecting wire 400 is rotatably engaged with the connector body 100 through the screw-on component 300. When the HDMI cable is inevitably bent and deformed due to long-term use, the screw-on component 300 is unscrewed from the connector body 100, and the screw-on component 300 and the connecting wire 400 are replaced without replacing all parts, which is not only easy to disassemble, but also low in cost.

[0035] Specifically, the screw-on component 300 has a screw-on end 301 that is rotatably engaged with the connector body 100, and a knob end 302 that is away from the screw-on end 301. The screw-on end 301 is a buckle, and the connector body 100 has a slot 101 that is rotatably engaged with the screw-on end 301. The connector body 100 has two oppositely disposed notches, which are connected to the slot 101. When working, the buckle enters the slot 101 from the two notches, thereby rotatably engaging the screw-on component 300 with the connector body 100.

[0036] As a preferred mode of this embodiment, a screw rod 303 threadedly connected to the joint body 100 is arranged between the screw-on end 301 and the knob end 302, and a limit nut 304 is sleeved on the screw rod 303. By arranging the screw rod 303 threadedly connected to the joint body 100 on the screw-on component 300, the stability of the connection between the screw-on component 300 and the joint body 100 is further improved. When the buckle of the screw-on end 301 is inserted into the slot 101, the screw rod 303 and the joint body 100 are just screwed to the bottom. At this time, the limit nut 304 is rotated until it stops at the joint body 100, thereby preventing the screw-on component 100 from axial displacement during operation.

[0037] As a preferred mode of this embodiment, a plurality of strip protrusions 3021 are evenly distributed along the axial direction on the outer circumference of the knob end 302 . The design of these strip protrusions 3021 increases the friction between the knob end 302 and the knob end 302 , making it convenient for the user to rotate the screw-on component 300 .

[0038] As a preferred embodiment of the present invention, a mounting base 103 is provided on the connector body 100 near the plug 200, and a latch rod 102 is provided on the connector body 100 near the plug. The latch rod 102 is rotatably mounted on the mounting base 103 via a pin shaft 104, and a latch tongue 1021 is provided at one end of the latch rod 102 near the plug 200. When the plug 200 is inserted into the connection end, the latch rod 102 is pressed so that the latch tongue 1021 is stuck on the connection end to prevent the plug 200 from withdrawing from the connection end, thereby ensuring the stability of the plug 200 when connected to the connection end.

[0039] As a preferred mode of this embodiment, a spring 105 is arranged between the end of the buckle rod 102 away from the plug 200 and the connector body 100. Through the design of the spring 105, the buckle tongue 1021 on the buckle rod 102 can always be tightly pressed against the connection end, further ensuring the stability of the connection between the plug 200 and the connection end. When opening, only external force needs to be applied to the end of the buckle rod 102 away from the plug 200, and the buckle tongue 1021 is away from the connection end, thereby achieving the purpose of the plug 200 being separated from the connection end.

[0040] In summary, the present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable structure, easy disassembly, low cost, etc.

[0041] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
