Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, the first embodiment of the audio-visual equipment external connection socket of the present invention is a single-jack type. The socket is provided with a jack 1, and two parallel connecting columns 5 are arranged in the jack 1. The side of the jack 1 The wall is provided with a locking groove 2, and the port of the locking groove 2 is provided with a locking boss 3, and the side wall of the socket 1 opposite to the locking groove 2 is provided with a positioning protrusion 4 parallel to the length direction of the connecting column 5. In order to facilitate insertion, the head of the connecting column 5 can be set as a flat blade, which is the shape of the head of a flat screwdriver. In order to better connect with the audio-visual equipment, the connection surface between the socket and the audio-visual equipment can be provided with an elastic sealing gasket 6, which can not only play the role of buffering vibration, but also ...
