Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of more reliable and more stable electric tool direct current speed adjustment switch that is connected with external circuit.
For achieving the above object, the utility model provides a kind of electric tool direct current speed adjustment switch, comprise shell body and be loaded on the control circuit board in shell body, described shell body is made up of base and upper cover, the periphery of described upper cover is provided with the connecting plate extending to base direction, on described connecting plate, offer fastening hole, on the outer surface of described base corresponding be provided with can with the described fastening hole fixing discount that is interlocked, described control circuit board is detachably fixedly installed on base, on described control circuit board, be also provided with the link passing outside base, the link of described control circuit board is provided with the binding post being connected with external circuit, described binding post is made up of male terminal and female terminal, female terminal is fixed on control circuit board, be fixed on male terminal for the wire being connected with external circuit, and one end of described male terminal forms the plug plugging with described female terminal, the corresponding base boss that the other end of male terminal is formed spacing butt after described male terminal inserts female terminal that is provided with on described base, on described base boss corresponding offer for described in be fixed on the boss through hole passing on male terminal and for the wire being connected with external circuit.
The beneficial effects of the utility model are: adopt said structure, because adopting by the peg graft binding post that forms of male terminal and female terminal, the utility model realizes being connected of control circuit board and external circuit, therefore compared to existing technology, described control circuit board will be more reliable and more stable with being connected of external circuit, simultaneously, owing to going back the corresponding base boss that the other end of male terminal is formed spacing butt after described male terminal inserts female terminal that is provided with on described base, therefore after effectively avoiding described male terminal to insert female terminal, throw off because the external world is stressed, thereby described male terminal can be plugged on female terminal securely, further improve the reliability that described control circuit board is connected with external circuit.
The utility model can further be set to also be provided with a dust-proof cushion on end face that described male terminal and base boss connect, on described dust-proof cushion also corresponding offer for described in be fixed on the dust-proof cushion through hole passing on male terminal and for the wire being connected with external circuit, on described, cover and be also extended with and described binding post can be coated to upper cover outer cover in the inner, the periphery of described dust-proof cushion is clamped and fastened between upper cover outer cover and base boss.
Adopt further and arrange, set up dust-proof cushion, can effectively prevent that external dust from entering into switch inside, further extend the useful life of direct current speed adjustment switch provided by the utility model.
