AI Technical Summary
The traditional motor junction box has a flat fitting structure, which leads to gaps in the seams, affecting the waterproof and dustproof performance. In particular, the motor protection level is reduced in complex environments, and the sealing gasket is prone to aging and failure.
The corrugated sealed junction box structure is adopted, and the corrugated sealed junction box cover and the junction box base are connected by cross-notch hexagonal flange bolts, which increases the contact area and reduces the use of sealing gaskets.
The protection level of the motor is improved, the waterproof and dustproof effects are enhanced, the assembly time is shortened, and the cost is reduced.

Description
TECHNICAL FIELD
[0001] The utility model relates to motor technology field especially relates to a corrugated sealed motor junction box. BACKGROUND
[0002] The protection of the motor is a very big aspect of influencing the performance of the motor, and the protection of the motor junction part is particularly important. The junction box joint gap is prone to appear after long time use, thereby affecting the protection of the motor to the external impurities such as water and dust. Moreover, the motor is in the driving state, and the heat of the motor often causes the aging of the rubber pad between the motor shell and the junction box, thereby affecting the sealing performance.
[0003] At present, the domestic and foreign markets are developing the coastal wind power installation, and the yaw motor applied in the wind power field has more complex and changeable application environment, thereby having higher requirements on the motor protection, especially the water resistance, aging resistance and corrosion resistance.
[0004] In other words, the traditional motor junction box has the joint gap between the junction box cover and the junction box seat due to the plane fitting structure, thereby affecting the protection of the motor junction box part to the water and dust, and causing the reduction of the motor protection grade. SUMMARY
[0005] The utility model discloses a corrugated sealed motor junction box which can effectively enhance the waterproof and dustproof effect of the motor junction box, reduce the use of the sealing pad, effectively shorten the assembly time and reduce the cost of the motor.
[0006] To achieve the above object, the utility model adopts the following technical scheme:
[0007] A corrugated sealed motor junction box comprises a corrugated sealed junction box cover and a corrugated sealed junction box seat.
[0008] The corrugated sealed junction box seat is connected with the base through four cross recess hexagonal flange surface bolts, and the corrugated sealed junction box cover and the corrugated sealed junction box seat are assembled together and aligned with the corrugated groove. Meanwhile, the four cross recess hexagonal flange surface bolts are screwed into the mounting holes of the corrugated sealed junction box cover and the corrugated sealed junction box seat and tightened, so that the corrugated sealed junction box cover and the corrugated sealed junction box seat are tightly connected.
[0009] In actual application, the waterproof joint is assembled and tightened in the assembly hole of the corrugated sealed junction box seat.
[0010] Compared with the prior art, the corrugated sealed motor junction box has the following advantages:
[0011] In the corrugated sealed motor junction box provided by the present invention, the matching mode of the junction box cover and the junction box seat is changed from the plane matching in the prior art to the corrugated matching structure of the present application, thereby effectively increasing the contact area between the junction box cover and the junction box seat, and effectively reducing the risk of gaps appearing at the joints of the traditional structure due to long-term use and the risk of corrosion and failure of the sealing gasket, while alleviating the technical problem of poor waterproof and moisture-proof performance of the motor connection caused by poor sealing between the junction box cover and the junction box seat; therefore, the corrugated sealed motor junction box provided by the present invention effectively improves the overall protection level of the motor. In addition, since the use of the sealing gasket is reduced, the assembly time is effectively shortened, thereby greatly improving production efficiency and reducing manufacturing costs.
