Abstract
The utility model relates to a plastic gear transmission device which comprises a gear case with built-in transmission gear, an electric machine and a control circuit board. Wherein, a shaft of the electric machine is through the gear case and matching with the transmission gear. The utility model is characterized in that the control circuit board is a metal circuit board with crimp connection of a plurality of electric components and the metal circuit board is arranged in the gear case. Besides, a pin at the electric machine is directly connected with the metal circuit board. The utility model changes the prior printed board into the metal circuit board, the electric component is connected to the metal circuit board by crimp connection to be arranged in the gear case, thereby avoiding the electric component and the metal circuit board being corrupted by outside to contact wet air as well as the electric component and the metal circuit being impacted and bumped by outside force and other substances, improving the service life of product, greatly improving the connection performance of the electric component and the circuit board, ensuring reliability of the transmission device control and improving production efficiency.
Description
(1) technical field
The utility model relates to a kind of Plastic Gear Transmission device.
(2) background technique
In comprising, establishes in existing Plastic Gear Transmission device gear-box, motor and the control circuit board of driving gear, wherein, the rotating shaft of motor one end penetrates gear-box and matches with driving gear, the other end of motor is provided with control circuit board, and this control circuit board is to use special-purpose metal connector assembly, electronic component and track circuit board to be connected in the scolding tin mode.
The Plastic Gear Transmission device of said structure because control circuit board is in the outside of gear-box, not only is subject to extraneous burn into and directly contacts with humid air, and is subject to other material collision or impact, thereby causes control fault, and influences working life.In addition, metal connector assembly, electronic component and track circuit board are connected in the scolding tin mode, so manufacturing efficiency is lower.
(3) model utility content
The purpose of this utility model is to provide a kind of Plastic Gear Transmission device, by optimizing structure, improves the control reliability of this transmission device, and enhances productivity.
A kind of Plastic Gear Transmission device provided by the utility model, establish gear-box, motor and the control circuit board of driving gear in comprising, wherein, the rotating shaft of motor penetrates gear-box and matches with driving gear, it is characterized in that: described control circuit board is the metal circuit board of the some electronic components of crimping, and this metal circuit board is installed in the gear-box, and in addition, the pin that is provided with on motor directly links to each other with metal circuit board.
Owing to adopted above-mentioned technical solution, make the existing printed circuit board (PCB) that uses into metal circuit board, and electronic component is connected on the metal circuit board in the crimping mode, be installed in the gear-box together, thereby not only avoided electronic component and metal circuit board to be subjected to extraneous corrosion, the contact malaria, and avoided electronic component and metal circuit board to be subjected to external force, the impact of other material and collision, improved the working life of product, also improved simultaneously the switching performance of electronic component and circuit board greatly, guarantee the reliability of this transmission device control, also enhance productivity.In addition, omitted the metal connector assembly of the special use in the existing Plastic Gear Transmission device, optimized the structure of Plastic Gear Transmission device, made it reasonable more, compact, firm.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
As shown in Figure 1, the utility model, it is a kind of Plastic Gear Transmission device, establish gear-box, motor 3 and the control circuit board of driving gear 1 in comprising, wherein, gear-box is made up of base 21 and loam cake 22, rotating shaft band one gear 31 of motor 3, and the base 21 that penetrates gear-box matches with driving gear 1.Control circuit board is the metal circuit board 42 of the some electronic components 41 of crimping, and this metal circuit board 42 is installed in the base 21 of gear-box.In addition, the pin 32 that is provided with on motor 3 directly links to each other with metal circuit board 42.
