Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of audio visual connector, especially a spiral audio link line plug. BACKGROUND

[0002] The audio connection line plug (also called audio connector or audio plug) is widely used in audio signal transmission equipment such as communication, stage performance audio box connection, and accessories of audio electronic products such as earphones and microphones, which usually have audio plugs. The audio plug can realize the transmission of electric wave signals between different audio devices by being plugged into a matching audio female socket. The specific structure is that the conductive air pipe part of the audio plug tightly matches the inner wall of the audio female socket, thereby realizing the transmission of electric wave signals.

[0003] Chinese patent publication (announcement) number: CN212380673U discloses an audio plug and an audio device, the audio plug is inserted into the female hole seat of the audio device and is buckled with the female hole seat. Specifically, the shape structure of the existing audio plug can be optimized, a anti-loosening buckle position is added to the audio plug, the audio plug is inserted into the female hole seat, the audio plug is rotated, the buckle position on the audio plug is engaged with the buckle position on the female hole seat, the fixed effect is achieved, and the loosening is prevented. The technical scheme solves the technical problem that the connection between the sound source and the power amplifier device of most acoustic devices is mainly through two connection modes: Bluetooth / WiFi and audio line. The audio line realizes the transmission of electric wave signals through connectors and wires. The commonly used 2.2 audio line is a bridge between the sound source and the power amplifier system, and is directly plugged in through the butt plug (male plug and female plug plug-in butt connection mode), which is simple and convenient. However, the disadvantage is that when the wire length is too short and is pulled, when the transportation is bumpy, and when the plug is not inserted in place due to human error, the plug contact is poor, the signal transmission fails, and the labor cost of detection and maintenance is increased.

[0004] In actual production, since the outer diameter of the conductive air pipe part of the audio plug and the inner wall of the audio female socket have manufacturing tolerances, when two parts with extreme tolerances are assembled, the fastening degree after assembly will be loose, thereby affecting the transmission effect of the audio signal and bringing bad auditory enjoyment and entertainment experience to the user.

[0009] As an improvement of the utility model, the depth of the spiral small groove is A, A is less than half of the wall thickness of the conductive air pipe part, but not less than one fourth of the wall thickness of the conductive air pipe part. The purpose of selecting this design is that the spiral small groove cannot be too deep, which will affect the strength of the conductive air pipe part; the spiral small groove also cannot be too shallow, which will not be easy to deform the conductive air pipe part when turning.
