Technical Field

[0001] This application relates to the field of high-speed air duct technology, and in particular to a terminal for connecting the heating frame of a high-speed air duct 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

[0033] 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.

[0034] 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.

[0035] 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 (thermistor) signal wire, and negative ion generator connection wire. This connection method reveals the following significant drawbacks during manufacturing and subsequent maintenance:

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Please see Figures 1 to 3In order to solve one or all of the above problems, this application proposes a terminal for connecting a high-speed air duct heating frame to a control board, including: a plug-in section 13, a riveting section 14, and an anti-tipping hook 15.

[0042] The plug section 13 has a rectangular cross-section plug structure 131 for plugging into a socket.

[0044] Anti-tipping hook 15 is set on the side wall of the terminal for connecting the high-speed air duct heating frame and the control board. It is used to engage with the groove wall of the plastic part of the heating frame to prevent the terminal from tipping over after insertion.

[0045] In this embodiment, the application of terminals for connecting the high-speed air duct heating frame and the control board allows for a plug-in connection between the heating frame and the control board, eliminating the need for wire connections. This replaces the traditional wire soldering method, saving the steps of manually drilling, fixing, and soldering wires one by one. It also eliminates the risk of damage to the control board caused by manual soldering, the impact of no wires on the air duct, and the risk of short circuits between no wires and the heating wire.

[0051] In one embodiment, the anti-tipping hook 15 has a 90° bend structure.

[0052] It should be noted that the 90° bend structure in this application means that the anti-tipping hook 15 includes two parts: a vertically arranged anti-tipping connecting section 151 and an anti-tipping hook section 152. It should also be noted that in this embodiment, the 90° bend or vertical arrangement refers to the anti-tipping connecting section 151 and the anti-tipping hook section 152 being approximately vertically arranged. In actual product manufacturing, there may be angular errors, and within the normal error range, these should be within the scope of protection of this application.

[0053] In one embodiment, the terminal surface for connecting the high-speed fan heating frame to the control board 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.

[0054] In one embodiment, the terminals used for connecting the high-speed air duct heating frame to the control board are arranged in an L-shape.

[0055] In one embodiment, the terminal for connecting the high-speed air duct heating frame to the control board further includes an L-shaped connecting body 16.

[0056] The connecting body 16 includes a plug-in body section 161 connected to the plug-in section 13 and a riveting body section 162 connected to the riveting section 14.

[0057] The plug-in main body section 161 and the riveted main body section 162 are set at 90°.

[0058] In one embodiment, the riveting section 14 further includes a riveting connecting strip 143 that connects the annular riveting structure 141 and the connecting body 16.

[0059] The inner wall 1431 of the riveted connecting strip 143 is narrowed inward by step 12, and the outer wall 1432 of the riveted connecting strip 143 is narrowed inward by slope.

[0060] In one embodiment, the plug segment 13 further includes a plug connection segment 132 that connects the plug structure 131 and the connection body 16.

[0061] The inner wall 1311 of the insert structure narrows inward through the step 12 structure, and the outer wall 1312 of the insert structure 131 widens outward through the step 12 structure.

[0062] The anti-tipping hook 15 is set on one side of the outer wall 1312 of the insert structure 131.

[0063] This application also provides a high-speed air duct including terminals for connecting the high-speed air duct heating element to the control board.
