Description

Technical Field

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

The control board, handle assembly, and heating element assembly with the connector mounted can be assembled by plugging them in. This connector replaces the traditional wire soldering method with a plug-in and socket connection method for connecting the control board, handle assembly, and heating element assembly.

[0012] Preferably, all the reed terminals are interference-fitted into the socket.

[0017] 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.

[0018] 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.

[0019] 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: 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.

[0020] Significant risks to welding quality: High-frequency manual soldering 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 soldering 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.

[0021] 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.

[0022] 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.

[0023] 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 manufacturing transformation. A new electrical connection structure is urgently needed to simplify the assembly process, improve reliability, and accommodate the demands of automated production.

[0024] Please see Figure 1 and Figure 2 To address one or all of the above problems, one embodiment of this application proposes a connector for connecting a high-speed air blower mainboard to a heating element and a handle.

[0025] In this embodiment, by setting up a socket with a jack 110, the handle assembly and the heating frame assembly can be connected simply by plugging them into the jack 110, replacing the traditional wire soldering method. This eliminates the steps of manually drilling, fixing, and soldering wires one by one, avoids damage to the control board caused by manual soldering, avoids the impact of wireless wires on the air duct, avoids the risk of short circuits between wireless wires and heating wires, and the application of the socket enables the automation of the mechanism assembly, improving production efficiency and reducing manufacturing costs.

The socket 110 also includes a heating wire power supply socket 114, an NTC signal socket 115, and a negative ion power supply socket 116, which are respectively connected to the heating frame assembly.

[0029] Specifically, in this embodiment, the connector for connecting the high-speed air blower motherboard, heating frame, and handle is a connector that integrates the functions of connecting to the handle and connecting to the heating frame assembly. The connector is connected to the handle via: neutral wire connection socket 111, live wire connection socket 112, and handle button board connection socket. The connector is connected to the heating frame assembly via: heating wire connection socket, NTC connection socket, and negative ion connection socket.

[0030] The use of connectors allows for simple plug-in connections between the control board and the handle and heating element components, eliminating the need for manual drilling, fixing, and soldering of neutral, live, handle button board, heating element, NTC, and negative ion wires. This also avoids damage to the control board caused by manual soldering, prevents interference with airflow, and eliminates the risk of short circuits between wires and the heating element. Furthermore, the use of connectors automates the assembly of the mechanism, improving production efficiency and reducing manufacturing costs.

[0031] In addition, this product is easy to disassemble and repair because it is assembled by plugging in. The manufacturing of the connectors can be automated, the application of the connectors enables the manufacturing of the control board to be automated, and the assembly of the finished product mechanism and handle can be automated, thereby improving production efficiency and reducing manufacturing costs.

The two heating wire power supply sockets correspond sequentially to the neutral wire connection socket and the handle button panel signal socket, respectively, and the live wire connection socket is located between the neutral wire connection socket and the handle button panel signal socket.

[0034] Please see Figure 1 In one embodiment, spring terminals 12 are respectively provided inside the socket 110 for forming stable contact with the corresponding insert.
