Description

Technical Field

[0001] The utility model relates to the technical fields of audio connectors and the like, and in particular to a mute audio plug. Background Art

[0002] Audio connectors are widely used in audio signal transmission equipment such as communications, such as speaker connections for stage performances. However, in actual applications, existing equipment often has shortcomings such as popping sounds. In addition to equipment problems, user carelessness is also a common cause. For example, a guitarist forgets to turn off the power of the speaker after a performance because he is eager to leave the stage and unplugs the plug at the guitar end. This will cause the speaker to produce popping sounds or even damage the equipment.

[0003] For example, patent CN202172186U discloses a 6.3 silent connector with a switch. Although it solves the problem of popping sounds, it still requires manual pressing of the switch to solve the problem of popping sounds. For people who are not familiar with the equipment, they may not press the switch or even if they are familiar with it, they may forget to press it, which makes it inconvenient to use.

[0004] For example, patent CN207353515U discloses an audio plug, which realizes automatic conversion between mute and transmission, but the mute protrusion is prone to breakage during use, or the mute protrusion does not rebound after repeated use, resulting in mute failure. Utility Model Content

[0005] In view of this, in order to solve the above problems, the purpose of the utility model is to provide a silent audio plug, which includes:

[0006] Wire clamp, welding sheet, insulating sheet, screw thread body, spring, internal pipe assembly, external silent movable empty pipe, clamp head, connector conductive rivet nail;

[0007] The conductive rivet of the connector sequentially penetrates the wire clamp, the welding sheet, the insulating sheet, the screw thread body, the spring, and the internal tube assembly, and is finally fixed to the clamp;

[0008] The external silent movable hollow pipe is sleeved on the outer wall of the internal pipe assembly;

[0009] The external silent movable hollow tube and the clamp head can be movably contacted or separated;

[0010] A certain gap may be provided between the external silent movable hollow tube and the screw thread body, the spring is located in the gap, and the two ends of the spring are respectively against the screw thread body and the external silent movable hollow tube.

[0011] The above-mentioned silent audio plug, wherein the internal tube assembly includes: an internal insulating tube, an internal conductive fixed empty tube, and insulating plastic; the internal insulating tube extends from the direction of the clamp head toward the direction of the screw thread body until it abuts against the insulating sheet, and the internal insulating tube is sleeved on the conductive rivet pin of the connector; the internal conductive fixed empty tube extends from the direction of the clamp head toward the direction of the screw thread body until it extends into the interior of the screw thread body, and the internal conductive fixed empty tube is sleeved on the internal insulating tube, the spring is sleeved on the internal conductive fixed empty tube, and the insulating plastic is sleeved on one end of the internal conductive fixed empty tube close to the clamp head.

[0012] In the above-mentioned silent audio plug, the longitudinal cross-section of the wire clamp is in the shape of a mountain.

[0013] In the above-mentioned silent audio plug, the screw thread body includes: a threaded end and a clamping head end; the longitudinal cross-section of the clamping head end is approximately trapezoidal, and the other surface of the clamping head end extends outward to form the threaded end.

[0014] In the above-mentioned silent audio plug, a surface of the clamp head end is inwardly recessed to form a first groove, and one end of the spring is arranged in the first groove.

[0016] Compared with the prior art, the above technical solution has the following positive effects:

[0017] Through the application of the utility model, a mute audio plug is provided. When the audio plug is not inserted into a speaker device, the external mute active tube contacts the clamp head and the conductive rivet pins of the connector, so that the audio plug is in a mute state. Only when the plug is inserted into the socket of the speaker, the external mute active tube does not contact the clamp head and the conductive rivet pins of the connector, and the audio plug can be transmitted normally. The audio plug does not need to press any switch in the conversion between transmission and mute, and the on-off is automatically realized, which is convenient and quick, and is not easy to be damaged during the plug-in and unplug process.

[0023] The conductive rivet pin 8 of the connector passes through the wire clamp 1, the welding sheet 2, the insulating sheet 3, the screw body 4, the spring 5, and the internal tube assembly 7 in sequence, and is finally fixed to the clamp 9; the wire clamp 1 is fixed to the screw body 4; the external silent movable empty tube 6 is sleeved on the outer wall of the internal tube assembly 7; the external silent movable empty tube 6 and the clamp 9 can be movably in contact or away from each other; a certain gap can be set between the external silent movable empty tube 6 and the screw body 4, the spring 5 is located in the gap, and the two ends of the spring 5 are respectively against the screw body 4 and the external silent movable empty tube 6.

[0024] During actual use, the mute audio plug is fixedly connected as a whole by the conductive rivet pin 8 of the connector. When the plug is not inserted into the speaker jack, the external mute movable hollow tube 6 contacts the clamp head 9 to form a short-circuit state, that is, a mute state.

Even if the mute audio plug of the device is unplugged without turning off the power of the speaker, the external mute movable hollow tube 6 contacts the clamp head 9 to form a short-circuit state, and no popping sound will be generated. Moreover, the mute plug only needs to be normally unplugged or inserted to prevent the popping sound from being generated, and no other operations are required.

[0025] The utility model also has the following implementation methods based on the above:

[0026] Further, a silent audio plug, wherein the internal tube assembly 7 comprises: an internal insulating tube 701, an internal conductive fixed hollow tube 702, and an insulating plastic 703; the internal insulating tube 701 extends from the direction of the clamp head 9 toward the direction of the screw thread body 4 until it abuts against the insulating sheet 3, and the internal insulating tube 701 is sleeved on the conductive rivet pin 8 of the connector; the internal conductive fixed hollow tube 702 extends from the direction of the clamp head 9 toward the direction of the screw thread body 4 until it extends into the interior of the screw thread body 4, and the internal conductive fixed hollow tube 702 is sleeved on the internal insulating tube 701, the spring 5 is sleeved on the internal conductive fixed hollow tube 702, and the insulating plastic 703 is sleeved on one end of the internal conductive fixed hollow tube 702 near the clamp head 9.

When the clamp 9 is inserted into the speaker jack, the external mute movable hollow tube 6 squeezes the spring 5 and separates from the clamp 9, the short circuit state disappears, and an output route is formed, so that the speaker makes a sound. When the clamp 9 is pulled out of the speaker jack, the spring 5 recovers its deformation and squeezes the external mute movable hollow tube 6, so that the external mute movable hollow tube 6 contacts the clamp 9, forming a short circuit state, that is, a mute state.

[0027] Furthermore, a silent audio plug is provided, wherein the longitudinal cross-section of the wire clamp 1 is in a mountain shape.
