[0028] Most disposable dental handpieces on the market are powered by built-in button batteries. However, this reliance on button batteries has significant limitations. Button batteries have limited capacity, and quality issues can affect normal use. Therefore, referring to... Figures 1 to 4This utility model provides a quick-connect electrical connector for disposable dental handpieces, and the following embodiments are provided:

[0029] The quick-connect electrical connector for a disposable dental handpiece includes an adapter block 100, terminals 200, and an adapter base 300. The adapter block 100 has two electrical mounting holes 120. There are two terminals 200, which are cylindrical, hollow, or solid. The two terminals 200 pass through the two electrical mounting holes 120 one-to-one. The adapter block 100 also has multiple insertion holes 110, through which the air inlet pipe, water inlet pipe, and atomizing pipe of the dental handpiece pass. The adapter base 300 has an insertion slot 320 for insertion into the dental handpiece handle. The bottom of the insertion slot 320 has an air inlet slot, a water inlet slot, an atomizing slot, and an electrical slot 310. When the adapter base 300 is inserted into the dental handpiece handle, the terminals 200 are inserted into the electrical slot 310, and the adapter block 100 is snapped into the bottom of the insertion slot 320.

[0030] When a disposable dental handpiece is used without a battery button and has an electrical connector, the terminal 200 is inserted into the adapter block 100, then the adapter block 100 is fitted onto the connecting end of the disposable dental handpiece, and then the adapter 300 is inserted into the connecting end of the disposable dental handpiece. At this time, the air inlet, water inlet, and atomizing tube of the dental handpiece are connected to the corresponding air inlet, water inlet, atomizing slot, and electrical slot 310, and the external power is conducted to the handle of the disposable dental handpiece to power its lighting. This connector eliminates the need for a button battery in the disposable dental handpiece, further reducing costs.

[0031] Furthermore, for disposable dental handpieces equipped with button batteries and those without electrical connectors, during use, terminal 200 is removed from adapter block 100, then adapter block 100 is fitted onto the connecting end of the disposable dental handpiece, and then adapter socket 300 is plugged into the connecting end of the disposable dental handpiece. Normal connection and use are also possible in this case. In this mode, the quick-connect electrical connector does not provide power to the disposable dental handpiece; the power for the lighting is provided by the button battery or other means. Therefore, this application has disposable dental handpieces that can be adapted to various specifications, offering a wide range of compatibility.

[0032] Terminal 200 can specifically be a sheet terminal 200, a ring terminal 200, a pin terminal 200, etc. In some other embodiments, the number of terminals 200 can also be one, specifically a single-pole connector. Dual terminals can be used for different functions, such as power + signal, positive + negative, to meet more complex electrical connection requirements and provide a more robust connection.

[0033] Further improvements, refer to Figure 4The device also includes a fixing block 400, which has a through hole 410 through which two terminals 200 pass. The fixing block 400 is snapped onto the connecting end of the disposable dental handpiece and is located on the side of the adapter block 100 away from the bottom of the slot. In use, both terminals 200 are simultaneously inserted into the adapter block 100, then the adapter block 100 is fitted onto the connecting end of the disposable dental handpiece, and finally the adapter 300 is inserted into the connecting end of the disposable dental handpiece. For disposable dental handpieces equipped with a button battery or without a power connector, in use, both terminals 200 and the fixing block 400 are removed together from the adapter block 100, then the adapter block 100 is fitted onto the connecting end of the disposable dental handpiece, and finally the adapter 300 is inserted into the connecting end of the disposable dental handpiece; this also allows for normal connection and use. The fixing block 400 can further fix the terminal 200, and when the terminal 200 is not in use, the two terminals 200 can be fixed together as one, making them less likely to be lost.

[0034] In a further improvement, the adapter block 100 is provided with a positioning groove 130, and the fixing block 400 is engaged with the positioning groove 130, serving to position the adapter block 100. The dual cooperation between the positioning groove 130 and the positioning step improves the assembly accuracy.

[0035] Further improvements include a disc-shaped adapter block 100. Since most machine handles are cylindrical for comfortable grip, the adapter block 100 is also designed in a disc shape to match the connection end of the handle. The disc-shaped structure of the adapter block 100 matches the cylindrical grip end of the handle, ensuring alignment and operational comfort during connection. The adapter block 100 is made of an elastic material, such as rubber, and forms a snap-fit ​​connection with the fixing block 400 through the annular positioning groove 130. This allows for quick installation and disassembly, while the elastic deformation enhances connection stability and effectively reduces the transmission of mechanical vibration.

[0036] In a further improvement, the bottom of the insertion slot 320 is provided with a positioning step. The positioning step structure at the bottom of the insertion slot 320 not only limits the insertion depth of the adapter block 100, but also disperses axial stress and improves the durability of the connection part.

[0037] Further improvements include an adapter 300 containing an air inlet pipe connected to the air inlet slot, a water inlet pipe connected to the water inlet slot, an atomizing pipe connected to the atomizing slot, and a power cord connected to the electrical slot 310. This provides power, air, and water supply for the disposable dental handpiece. The adapter 300 employs a multi-channel integrated design, with independent air inlet pipes, water inlet pipes, atomizing pipes, and power cord channels, each corresponding to different functional interfaces on the handpiece. Each channel utilizes an anti-interference layout to ensure that media delivery does not interfere with each other.

[0038] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
