Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a power signal combination connector. Background Technology

[0002] HDMI is a fully digital audio-visual transmission interface used to connect various high-definition devices, such as TVs, computers, and game consoles. It can transmit high-definition video and audio signals simultaneously. The design of HDMI simplifies device connection and avoids the cumbersome process of connecting audio and video cables separately, as required by traditional analog interfaces.

[0003] However, the aforementioned HDMI interface can only transmit audio and video signals and cannot power external devices. This means that some devices that rely on external power must be connected to a separate power supply, which is not simple to use and increases the complexity of cables and power management. Compared with interfaces that support power supply, such as USB-C and Thunderbolt, HDMI cannot combine video, audio and power supply into one, making it unsuitable for portable expansion needs between devices. In view of this, we propose a power signal combination connector. Utility Model Content

[0004] The purpose of this invention is to provide a power signal combination connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power signal combination connector, comprising a cable, wherein connecting components are provided at both ends of the cable, and the connecting components include:

The male HDMI 3 is electrically connected to the female HDMI 9, and the male connector male pin 2 is electrically connected to the female connector female pin 6. The male HDMI 3 and the female HDMI 9 transmit video and audio signals, and the male connector male pin 2 and the female connector female pin 6 provide power to external devices.

[0030] Terminal 14 is inserted into the connecting positioning part 15. The outer wall of terminal 14 is fixedly connected with injection-molded rubber 13. Terminal 14 is electrically connected to the end of the cable away from the inner core 5 of the female head. The internal threaded copper post 16 is fixedly connected to the outer wall of injection-molded rubber 13.

[0031] The internally threaded copper post 16 is sleeved with the button clip fastener 17. A pin 21 is inserted into the side wall of the button clip fastener 17. A torsion spring 19 is sleeved on the outer wall of the pin 21. The pin 21 is hinged to the snap button 20. The internally threaded copper post 16 is threadedly connected to the locking screw 18.
