Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a plug-in type connection terminal and a connection sleeve thereof. Background Art

[0002] With the continuous advancement of hearing aid technology and people's increasing attention to hearing health, the reliability and comfort of hearing aids have become the focus of continuous attention of R&D personnel. Hearing aids can better help people with hearing loss to return to normal life through their sophisticated electronic components and design. However, these precision components are in contact with the external environment and must have excellent durability and corrosion resistance to maintain their optimal working condition for a long time. Terminals are an important part of hearing aids and are mainly used to connect other electronic components for signal transmission. However, traditional materials are easily affected by external environmental corrosion during long-term use, resulting in a decrease in the working performance of hearing aids. Therefore, it is particularly important to find a material and process that can improve the stability and corrosion resistance of terminals.

[0003] In order to ensure that hearing aids can maintain good performance in various environments, many studies are devoted to improving the manufacturing technology of hearing aid terminals. Gold plating, as a common surface treatment process, can effectively improve the corrosion resistance and oxidation resistance of metal surfaces. This is because it can form an extremely dense gold layer on the metal surface. This gold layer can not only protect the internal metal from corrosion, but also effectively reduce the wear between the contacts, thereby increasing the service life of the terminals and the stability of signal transmission. This surface treatment technology is particularly important in precision equipment such as hearing aids. The gold plating layer can not only prevent oxidation and corrosion of the metal surface, but also improve the conductivity, making signal transmission more stable and reliable.

[0004] However, during the gold plating process of these tiny terminals, two major problems are often encountered: first, the gold plating layer may block the plug-in hole of the terminal, resulting in insufficient coverage of the gold plating layer on the inner wall when the terminal is plugged in and out; second, the gold plating layer may become too thick, making it difficult for the gold-plated female terminal to cooperate with the male terminal smoothly, affecting the normal operation of the hearing aid. Therefore, it is necessary to develop a new plug-in terminal to increase the success rate of terminal gold plating. Summary of the invention

[0005] The purpose of the present invention is to provide a plug-in connection terminal, which aims to solve the technical problem in the prior art that the gold-plated layer may block the plug-in hole of the terminal, resulting in insufficient coverage of the gold-plated layer on the inner wall when the terminal is plugged in and out; the gold-plated layer may also become too thick, making it impossible for the gold-plated female terminal and the male terminal to cooperate smoothly, affecting the normal operation of the hearing aid.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides a plug-in type connection terminal, comprising a terminal body, the terminal body comprising a plug-in portion and a connection portion, one end of the plug-in portion is connected to one end of the connection portion, the connection portion is used to connect to a wire, and the plug-in portion is used to match another plug-in terminal.

The second section is arranged between the first section and the second section, and the second section is parallel to the first section and the third section. One end of the first bending section is connected to one end of the first section, and the other end is connected to one end of the second section. One end of the second bending section is connected to one end of the third section, and the other end is connected to the other end of the second section. The first bending section is parallel to the second bending section.

[0008] The embodiment of the present invention also provides a connection sleeve, including a pluggable connection terminal and a mounting sleeve, wherein the mounting sleeve is provided with two mounting holes, the mounting holes penetrate the mounting sleeve, and the mounting holes are used to mount the pluggable connection terminal.

[0009] Furthermore, the mounting hole comprises an arc hole and a placement hole, one end of the placement hole is connected with one end of the arc hole, the arc hole is for the arc connecting plate to pass through, and the placement hole is used to place the plug-in sleeve.
