Double-channel audio plug and riveting plug connector thereof

Abstract

The invention discloses a double-channel audio plug and a riveting plug connector thereof. The double-channel audio plug comprises an insertion core, a first expansion tube, an inner tube, a second expansion tube, an outer tube and a plug top cover, wherein the insertion core, the first expansion tube, the inner tube, the second expansion tube and the outer tube are sequentially nested from insideto outside, and the lower part of the insertion core is inserted into the plug top cover. The riveting plug connector comprises a first riveting piece, a second riveting piece, a third riveting piece, an attaching strip, a first inserting portion and a second inserting portion, wherein the first inserting portion and the second inserting portion in the current plug connector are aligned to the corresponding positions and driven into the double-channel audio plug, then the wires corresponding to a signal cold terminal, a grounding terminal and a signal hot terminal are respectively placed on the first riveting piece, the second riveting piece and the third riveting piece, and the three riveting pieces are bent to respectively compress the wires by means of riveting wire connection, therebyavoiding the connection by manual welding, solving the problem of poor welding spots, and improving the processing efficiency.

Description

technical field [0001] The invention relates to the field of audio plugs, in particular to a two-channel audio plug and a riveted plug connector thereof. Background technique [0002] The isolation structure between the inner core and the outer tube in the traditional two-channel audio plug is usually formed by injecting plastic through an injection molding machine, and one end of the two-channel audio plug is left with a solder joint corresponding to the signal hot end, signal cold end and ground end. Therefore, in the production process of the two-channel audio plug with this structure, it is necessary to manually place the hardware (metal parts such as the inner core and the outer tube) in the plastic mold, which is difficult to process, requires high precision, and consumes a lot of energy. At the same time, affected by many factors such as humidity, temperature, speed, pressure and time during injection molding, problems such as inner core deviation, injection molding b...
