Description

Audio plugs and their connectors

【Technical field】

The utility model relates to an audio plug, in particular to an audio plug which can be directly welded to a printed circuit board and a connector using the audio plug.

【Background technique】

Traditional electronic products are generally equipped with data interface, audio interface, and power interface, which greatly increases the volume of electronic products, which is contrary to the development trend of existing electronic products, so some electronic products only have one audio interface. It can realize power transmission, data transmission and the insertion and use of earphones, which reduces the setting of sockets in the product and reduces the volume of the product. However, the direct transmission of power and data through audio jacks has not yet been fully popularized, so users will choose audio plug connectors to realize the transmission of audio and power, and audio and data.

For example, in the audio connector assembly disclosed in Chinese Patent No. 200420008904.0, the audio plug is connected to the USB through a four-core cable, and the user can realize data and power transmission through the cable. However, the length of the cable is long, and it takes up a lot of space in daily use, which is not convenient for users to carry; the patch cord may be twisted and knotted, which is not suitable for tidying up; and the product needs to consume wire materials, which increases the product cost.

As disclosed in U.S. Patent No. 6,616,487, the cable is usually directly soldered to the tail end of the audio plug, because the audio plug has multiple terminals, and the arrangement is relatively close, so it is necessary for the manufacturer to connect multiple wires in a small space. Cables are soldered to different terminals, which increases manufacturing difficulty.

Therefore, it is necessary to provide an audio plug that can be directly soldered to a printed circuit board.

【Content of utility model】

The main purpose of the utility model is to provide an audio plug, especially an audio plug that can be directly welded to a circuit board.

In order to achieve the above purpose, the utility model provides an audio plug, including: several metal contact parts, the metal contact parts are separated by insulating materials; wherein the rear end of the audio plug connector is provided with a welding portion corresponding to each metal contact portion, and the welding portion has a flat plate-shaped welding plate welded to the circuit board.

Compared with the prior art, the audio plug of the utility model has the following effects: the flat welding plate can increase the welding area relative to the cable, which is convenient for welding and at the same time increases the stability of the product.

Another object of the present utility model is to provide an audio plug connector, especially an audio plug connector that realizes signal transmission between the audio plug and the adapter directly through the printed circuit board.

In order to achieve the above purpose, the utility model provides an audio plug connector, including: an audio plug, an adapter; the audio plug is provided with four metal contact parts, and each metal contact part is separated by an insulating material, wherein the audio plug and The adapters are connected through a printed circuit board, and a flat welding plate is provided at one end of the audio plug welded to the printed circuit board.

Compared with the prior art, the audio plug connector of the utility model has the following effects: the circuit board is transferred to the audio plug and the adapter, avoiding the complicated cable welding, saving materials and space; The part increases the welding space and reduces the difficulty of welding; and the hard circuit board replaces the soft cable, which increases the plugging strength of the audio plug and prolongs the service life.

【Detailed ways】

Please refer to FIG. 1 and FIG. 2 , the audio plug connector 100 includes an audio plug 1 , an adapter 2 , an adapter circuit board 3 , and a housing 4 .

Please refer to FIG. 1 and FIG. 2, in this embodiment, the adapter 2 adopts the universal serial bus interface (Universal Serial Bus, ie USB). In other embodiments, other types of interfaces, such as 1394 interfaces, may also be used.

Please refer to FIG. 3 , the audio plug 1 includes several metal contact parts 11 , in this embodiment, there are four metal contact parts 11 , and the metal contact parts 11 are separated by insulating material 12 . The metal contact portion 11 includes a front end 110 mated with a docking audio jack and a rear end 111 welded to the circuit board 3 . The front end 110 of the metal contact portion 11 is circular with the audio plug plugging and unplugging direction as the axis, and the rear end 111 is approximately circular. The rear ends 111 are respectively provided with soldering portions 13 having flat plate-shaped soldering plates 14 soldered to the circuit board 3 . The welding part 13 can be obtained by the following methods: obtaining the welding part 13 by integral molding; welding the welding plate 14 to the rear end 111 of the metal contact part 11 by welding; stamping and forming a main body part into a substantially circular ring, and forming a flat plate The welding portion 13 of the welding plate 14 , the ring of the welding portion 13 can be sleeved on the rear end 111 of the metal contact portion.
