Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a multi-interface audio socket connector. Background Art

[0002] The audio jack connector is an important component for connecting audio devices such as mobile phones and walkmans with headphone cables. There are two conductive plates inside the audio jack connector. After the audio plug of the headphone cable is inserted into the plug interface, it will contact the two conductive plates respectively. The conductive plates are welded on the PCB board of the audio device, so that the headphones can receive the sound signal of the audio device and play it. At present, there are two types of standard audio plugs in the market, 2.5mm and 3.5mm, according to the model of the audio plug. The main difference between the two audio plugs is the different radius. The general principle and structure are similar.

[0003] Although there are two standard audio plugs, the audio jack connectors on the market are only suitable for one of the two specifications. At present, the manufacturers of audio jack connectors solder a 2.5mm audio jack connector and a 3.5mm audio jack connector on the same circuit board, and then install them in the audio device, so that the audio device can be plugged with two audio plugs. Obviously, the above method has the following shortcomings: because the two audio plugs are arranged side by side on the PCB board during use, that is, the two audio plugs need to be placed side by side before the welding process can be carried out, which undoubtedly increases the time required for assembly and welding.

[0004] For this reason, there are currently multi-interface audio jack connectors on the market, which have a first plug interface for inserting a 2.5mm audio plug and a second plug interface for inserting a 3.5mm audio plug, which can solve the above problems well. However, this multi-interface audio jack connector has an elastic pad inside that provides elastic force to the conductive sheet or the contact sheet. The elastic pad is made of silicone material, which is not durable and has a relatively weak supporting elastic force, so that the plugging and unplugging force of the audio plug is relatively small and cannot meet the needs of use. Therefore, it is necessary to improve the current multi-interface audio jack connector. Utility Model Content
