Description

Audio connector and audio transmission device

The present invention relates to an audio connector, and more particularly to an audio connector capable of reducing noise and an audio transmission device.

Generally speaking, when playing music in a wide range of places, a player (for example, a CD player or an mp3 player) is usually connected to an amplifier, and then the amplifier is connected to a speaker for zooming in. The volume of the music allows the people present to hear the music clearly. However, since an audio source cable connected to the amplifier cannot be directly inserted into a socket of the speaker, the audio source cable is usually installed in an audio connector that can be directly inserted into the socket. Another way to expand the sound is to use the audio connector between an audio cable of an electroacoustic instrument (eg, an electric guitar) and the speaker, which can also amplify the volume of music from an electroacoustic instrument.

Referring to FIG. 1, a known audio connector is suitable for connecting the audio source cable 10, and includes a terminal unit 11 for inserting the socket (not shown), and an outer portion made of a conductive material. The base unit 12. The sound source connecting wire 10 includes a plurality of wires 101, and a shielding layer 102 surrounding the wires 101 and made of a conductive material.

The terminal unit 11 includes a first conductive seat 111 , a second conductive seat 112 spaced around the first conductive seat 111 , and a first assembled between the first conductive seat 111 and the second conductive seat 112 . Insulating material 113. The outer tube base unit 12 is screwed on the second conductive seat 112, and the sound source connecting line 10 can be fixed by a loop.

The first conductive seat 111 includes a base portion 114 made of metal or alloy material, and an extension portion 115 that is coupled to the base portion 114 and has a material different from the base portion 114. The second conductive seat 112 is entirely made of a conductive material such as metal or alloy.

When the audio connector is connected to the sound source cable 10 and the socket in a use state, the first conductive seat 111 of the terminal unit 11 is used for transmitting an audio source signal, and the second conductive seat 112 is used for grounding, and the The outer tube base unit 12 is in direct contact with the shield layer 102 of the sound source connection line 10. However, since the second conductive seat 112 is used for grounding, the outer base unit 12 needs to be screwed, so that the second conductive seat 112 can also be electrically connected to the outer base unit 12. The outer tube base unit 12 absorbs the noise that should be blocked by the shielding layer 102, and transmits the noise to the speaker, causing the concert played by the speaker to be affected by the noise and degrading the playing quality of the music. . In addition, in actual use, the user cannot completely insert the audio connector along the axis of the audio connector, so that the audio connector is somewhat twisted; and since the base portion 114 and the extension portion 115 of the first conductive seat 111 are only riveted In the combined manner, the first conductive seat 111 is also prone to withstand excessive torsional forces and breaks from the weaker joints, resulting in an open circuit and inability to transmit signals. Furthermore, the connection of the base portion 114 and the extending portion 115 by riveting also causes a problem that the resistance value of the first conductive seat 111 is high. On the other hand, since the first conductive seat 111, the insulating material 113 and the second conductive seat 112 are only assembled around each other, this also causes the coaxial structure to have poor anti-rotation capability, resulting in the audio connector being passed through. After the inevitable twisting in the process of the second insertion and removal, the welding between the audio connector and the sound source connecting wire 10 is broken due to the twist, resulting in damage of the circuit breaker.

Accordingly, it is an object of the present invention to provide an audio connector that is capable of improving at least one of the disadvantages of the prior art.

Therefore, the audio connector of the present invention is suitable for connecting a sound source connector, and the audio connector comprises a terminal unit, an insulating material screw socket, and an outer cylinder base unit.

The terminal unit includes a first conductive seat adapted to be connected to the sound source connecting line and a second conductive seat spaced around the first conductive seat, and is mounted between the first conductive seat and the second conductive seat The first main insulation. The screw seat is sleeved on the second conductive seat of the terminal unit. The outer cylinder base unit is screwed on the screw socket to fix the sound source connection line.

Therefore, another object of the present invention is to provide an audio transmission device.

The audio transmission device includes a sound source connection line and two of the above audio connectors. The sound source connection line includes a plurality of wires, and a shielding layer surrounding the wires. The terminal unit of the audio connector is electrically connected to the wire of the sound source connecting wire, and the shielding layer of the sound source connecting wire is electrically connected to the terminal unit of one of the audio connectors.

The utility model has the advantages that: the screw socket of the insulating material and the connection manner of the shielding layer can be used for isolating the noise of the terminal unit of one of the audio connectors, and the audio transmission device can be pointed to another The terminal unit of the audio connector absorbs the direction of the noise, thereby improving the quality of the transmitted source signal.

The second main insulating member 25 has a short tubular shape and is disposed outside the front end portion of the first audio transmitting member 211 and away from the outer protruding portion 222 of the second conductive seat 22 . The second sub-insulating member 26 has a short tubular shape and is sleeved outside the rear end portion of the first audio transmission member 211. The second main insulating member 25 and the second sub-insulating member 26 are interposed between the first audio transmitting member 211 and the second audio transmitting member 212, so that the first audio transmitting member 211 and the second audio transmitting member The 212 spaces can be separated by a fixed distance and are not electrically connected.

Each of the latching members 27 is inserted through the outer protruding portion 222 of the second conductive seat 22, the first sub-insulating member 24, the second audio transmitting member 212, and the second sub-insulating member 26.

An inner sleeve 42 made of an insulating material and a screw 43 made of a conductive material. The front end portion of the barrel body 41 is screwed to the screw socket 3, and a screw hole 413 is bored in the rear end portion of the barrel body 41. Each inner sleeve 42 is radially provided with a fixing hole 421. The screw hole 413 of the barrel body 41 is in communication with the fixing hole 421 of the inner sleeve 42 . The screw 43 is screwed and threaded through the screw hole 413 and the fixing holes 421 to be used for positioning. The sound source connecting line 91 is disposed in the barrel body 41 and the inner sleeves 42.

In practice, the number of the inner sleeves 42 that are coaxially stacked can be determined according to the diameter of the sound source connecting line 91. When the diameter of the sound source connecting wire 91 is small, in order to provide a sufficient screw hole depth, two inner sleeves 42 are used, so that the screw 43 can be firmly locked into the barrel body 41 and The inner sleeve 42 is positioned to positively abut the sound source connecting line 91 and the center line of the sound source connecting line 91 is located at the axis L without being deviated. When the diameter of the sound source connecting wire 91 is large, one of the inner sleeves 42 may be selectively used or the inner sleeve 42 may not be used, that is, the screw 43 can be firmly pressed against the sound source connecting wire 91.

Referring to Figures 4 and 5, the audio connector 90 is adapted for use as a component of an audio transmission device. The audio transmission device includes the audio source connection line 91 and two of the above-mentioned audio connectors 90 connected to the audio source connection line 91.

The rear end portion of the terminal unit 2 of one of the audio connectors 90 of the audio transmission device is electrically connected to one end of the wire 911 of the sound source connection line 91. The outer sleeve unit 4 is screwed to the screw base 3 and sleeved to fix the sound source connecting line 91. The front end portion of the shielding layer 912 is combed into a wire shape and is directly in contact with and electrically connected to the second conductive seat 22. The front end portion of the terminal unit 2 can be inserted into the amplifier (or electroacoustic instrument) 94, and the sound source signal of the amplifier (or electroacoustic instrument) 94 can be guided. In more detail, each of the first audio transmission component 211, the second audio transmission component 212 (FIG. 4), and the second conductive housing 22 are electrically connected to the respective wires 911, and respectively serve as transmission left sounds. The channel signal, the right channel signal (that is, used to transmit two channels), and the grounding.

The terminal unit 2 of the other audio connector 90 of the audio transmission device is electrically connected to the other end of the wire 911 of the audio source cable 91. The outer sleeve unit 4 is screwed to the screw base 3 and sleeved to fix the sound source connecting line 91. The terminal unit 2 can be inserted into the speaker 92, and the sound source signal from the amplifier 94 (or electroacoustic instrument) of the preceding stage can be transmitted to the speaker 92 of the subsequent stage. Each of the first audio transmission component 211, the second audio transmission component 212, and the second conductive housing 22 are electrically connected to the respective wires 911, and are respectively transmitted from the preamplifier (or electroacoustic instrument). 94 left channel signal and right channel signal, and grounding. It should be noted that the shielding layer 912 of the sound source connecting line 91 does not contact the second conductive seat 22 of the audio connector 90 inserted in the downstream device.

Since the terminal unit 2 of the audio connector 90 inserted in the amplifier (or electroacoustic instrument) 94 is electrically connected to the shield layer 912 of the sound source connecting line 91, the amplifier (or electroacoustic instrument) 94 can be used to absorb impurities. News. On the other hand, the barrel body 41 of the audio connector 90 that is inserted into the speaker 92 is screwed to the screw socket 3 of the insulating material, so that the outer tube holder unit 4 and the second conductive seat 22 are not electrically connected. Therefore, the noise cannot be absorbed by the shielding layer 912 of the sound source connecting line 91 through the screw socket 3 by the second conductive seat 22. Therefore, the noise in the audio signal transmitted by the audio transmission device is absorbed by the pre-stage device (ie, the amplifier 94) and is not transmitted to the subsequent device (ie, the speaker 92), thereby improving the quality of the audio signal.

Secondly, since the first audio transmission member 211, the second audio transmission member 212, and the second conductive holder 22 are integrally formed, the resistance values of the first conductive seat 21 and the second conductive seat 22 can be reduced. The ability of the audio connector 90 to transmit audio signals. On the other hand, through the integrally formed first conductive seat 21 and the second conductive seat 22, the ability of the audio connector 90 to resist twisting can be improved, and the durability of the audio connector 90 can be improved. In addition, by using the design of the latch member 27, the first conductive seat 21, the second conductive seat 22, the first sub-insulating member 24 and the second sub-insulating member 26 of the terminal unit 2 can be positioned to enhance the audio. The anti-rotation ability of the joint 90 prevents the joint of the audio joint 90 and the wire from being broken due to twisting.

Furthermore, the first main insulating member 23, the first sub-insulating member 24, the second main insulating member 25 and the second sub-insulating member 26 are mounted on the first conductive seat 21 at intervals from each other, and can also be earlier than The technical audio connector uses less insulating material, that is, the second conductive seat 22, the first audio transmitting member 211 and the second audio transmitting member 212 can be spaced apart, thereby saving material cost.

Referring to FIG. 6 and FIG. 7, a second embodiment of the present type of audio connector 90 is similar to the first embodiment, except that the first conductive seat 21 of the terminal unit 2 only includes a front-rear extending along the axis L and The first audio transmission member 211 is surrounded by the first main insulating member 23 and the first sub-insulating member 24, and does not have the second audio transmitting member 212 as shown in FIG. The second conductive seat 22 is sleeved outside the first conductive seat 21 , and the first main insulating member 23 and the first sub-insulating member 24 are disposed on the first conductive seat 21 and the second conductive seat 22 . Opposite side. Each of the latch members 27 is radially disposed through the first audio transmission member 211, the first sub-insulation member 24, and the outer portion 222 of the second conductive seat 22.

Referring to FIG. 8, the second embodiment is applied as a component of the audio transmission device in a similar manner to the first embodiment as the audio transmission device. The difference is that the first audio transmission component of the audio connector 90 is The 211 is electrically connected to the wire 911 of the sound source connection line 91 to transmit a monophonic sound source signal.

With the design of the screw-on socket 3 of the insulating material, the audio transmission device of the second embodiment having the audio connector 90 can also achieve the absorption of noise by the pre-stage device to improve the quality of the sound source signal transmitted to the subsequent device.

In summary, the audio transmission device of the present invention utilizes the screw-on socket 3 of the insulating material of the audio connector 90, and the noise can be received by the pre-stage device when the single-ended ground is grounded, so that the noise is prevented from entering the subsequent device. It has a specific noise absorption directionality, which in turn improves the quality of the transmitted sound source signal. In addition, the integrally formed first conductive seat 21 and the second conductive seat 22 can resist twisting and increase the durability of the audio connector 90, so that the purpose of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
