Description

Technical Field

[0001] This application relates to the field of high-speed air duct technology, and in particular to a terminal for connecting negative ions to a control board. Background Technology

[0002] With the widespread application of high-speed hair dryers in the personal care field, the reliability, production efficiency, and maintainability of their internal electrical connections have become important directions for technological improvement in the industry. Traditional high-speed hair dryers typically employ a distributed wiring connection scheme, specifically: the control board and handle assembly are electrically connected via multiple independent wires (such as neutral, live, switch, and button wires); the control board and heating element assembly also require separate soldering of the heating wire power supply wire, NTC (thermistor) signal wire, and negative ion generator connection wire. This type of connection method results in complex and inefficient assembly processes during manufacturing and subsequent maintenance, significant potential for welding quality defects, and poor compatibility with automated production.

[0003] In summary, existing wiring connection solutions have become a key technological bottleneck restricting the improvement of high-speed wind tunnel product quality, optimization of production costs, and intelligent transformation of manufacturing. A new electrical connection structure is urgently needed to simplify the assembly process, improve reliability, and accommodate the demands of automated production. Utility Model Content

[0004] Based on this, this application provides a terminal for connecting negative ions to a control board. By providing an anti-tipping hook to prevent displacement or tilting after the terminal is inserted and a pin structure for riveting by automated equipment, the assembly of the heating frame can be automated, improving production efficiency and reducing manufacturing costs.

[0005] This application provides a terminal for connecting negative ions to a control board, including: The plug section is a rectangular cross-section plug structure used for plugging into the plug socket; The riveting section is a rectangular cross-section pin structure used to insert into the gap formed by bending the metal connecting piece of the negative ion component by 180° for riveting; the pin structure is provided with a positioning boss, which is used to limit the positioning with the boss in the groove of the heating frame plastic part, so that the riveting position of the pin and the negative ion connecting piece is aligned, and the pre-positioning before riveting is achieved. An anti-tipping hook is provided on the side wall of the terminal that connects the negative ion generator to the control board. It is bent and is used to engage with the limiting groove wall of the heating frame plastic part to prevent the terminal that connects the negative ion generator to the control board from tilting after insertion.

[0006] In the terminals for connecting negative ions to the control board described in the embodiments of this application, the terminals for connecting negative ions to the control board are formed by stamping metal sheets.

[0007] Preferably, the terminal is formed by stamping a metal sheet.

[0008] Preferably, the terminal surface is provided with a silver plating layer, a tin plating layer, a gold plating layer, or a nickel plating layer to improve conductivity and oxidation resistance.

[0011] Preferably, one side of the insertion segment is narrowed inward relative to one side of the riveting segment by a step, and the other side of the insertion segment is flush with the other side of the riveting segment.

[0012] Preferably, the insertion segment further includes an insertion connection segment connecting the riveting segment and the insert structure; One side of the insert structure narrows inward relative to one side of the plug-in connection section, and the other side of the insert structure widens outward relative to the other side of the plug-in connection section.

[0013] Preferably, the anti-tipping hook is located on the side of the insert structure that extends outward relative to the plug-in connection section.

[0016] The beneficial effects of this application are as follows: In this embodiment, the application of terminals for connecting negative ions to the control board allows the heating frame containing negative ion components and the control board to be connected, replacing the traditional wire welding method. This eliminates the steps of manually drilling, fixing, and welding wires one by one, avoids damage to the control board caused by manual welding, avoids the impact of wireless wires on the air duct, and avoids the risk of short circuits between wireless wires and heating wires.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0022] With the widespread application of high-speed hair dryers in the personal care field, the reliability, production efficiency, and maintainability of their internal electrical connections have become important directions for technological improvement in the industry. Traditional high-speed hair dryer electrical systems typically employ a distributed wiring connection scheme. Specifically, the control board and handle assembly are electrically connected via multiple independent wires (such as neutral, live, switch, and button wires), while the control board and heating element assembly require separate soldering of the heating wire power supply wire, NTC (negative temperature coefficient thermistor) signal wire, and negative ion generator connection wire. This connection method reveals the following significant drawbacks during manufacturing and subsequent maintenance: The assembly process is complex and inefficient: During the assembly stage on the production line, operators need to complete the wire threading, positioning and fixing, and multi-node welding (such as neutral wire, live wire, switch wire, etc.) one by one. The process is tedious and highly dependent on manual operation. At the same time, the large number of wires and their messy layout can easily interfere with the internal air duct structure, affecting airflow efficiency and even causing abnormal noises.

[0023] Significant risks to welding quality exist: High-frequency manual welding easily leads to process defects such as incomplete soldering and cold soldering, causing poor electrical contact or open circuit risks; the high temperature of the soldering iron during the welding process may also damage the surface components of the control board or the copper-clad traces, reducing product yield. In addition, exposed wires are prone to unexpected contact with high-temperature heating wires in confined spaces, causing insulation layer melting and short circuit faults.

[0024] Poor compatibility with automated production: Traditional wire connection methods, due to the high flexibility of the wires and the high requirements for positioning accuracy, are difficult to adapt to the standard operating procedures of automated equipment, which seriously restricts the scale and consistency of production.

[0025] High maintenance costs: When the control board malfunctions, maintenance personnel need to remove all soldered wires one by one before they can replace it. This is not only time-consuming and labor-intensive, but may also cause secondary damage due to operational errors during disassembly, further increasing maintenance costs.

[0026] In summary, existing wiring connection solutions have become a key technological bottleneck restricting the improvement of high-speed wind tunnel product quality, optimization of production costs, and intelligent transformation of manufacturing. A new electrical connection structure is urgently needed to simplify the assembly process, improve reliability, and accommodate the demands of automated production.
