Description
Technical Field
[0001] This utility model relates to the field of socket technology, and in particular to a 3-hole horizontal patch AV socket. Background Technology
[0002] AV sockets, also known as coaxial sockets, are audio and video interfaces for audio-visual equipment. A stands for audio and V stands for video. Generally, devices such as VCRs and DVD players have AV outputs, while display devices such as televisions have AV inputs, which can be used to connect digital home appliances such as cameras, DVDs, and other digital products.
[0003] An AV socket is one of the essential interfaces on every television. The AV cable connecting the two has three wires: an audio interface (red and white wires, forming the left and right channels) and a video interface (yellow). The AV interface separates the transmission of video and audio, thus avoiding mutual interference between audio and video.
[0004] Currently, the signal terminals of existing AV sockets and the pins of the switch moving and stationary pins usually need to be inserted into pre-drilled holes on the PCB and then soldered from the other side of the PCB. However, due to the large size of the structure, it occupies a lot of space on the board and requires manual assembly, resulting in high labor costs. Utility Model Content
