Abstract
The utility model relates to a controller, in particular to a motor drive controller, which comprises a shell, a base plate and a circuit board assembly arranged inside the shell, wherein the shell and the base plate are connected tightly, the edge of the shell is provided with a seal ring accommodating groove, a seal ring is arranged in the seal ring accommodating groove, and the shell and the base plate are sealed through the seal ring. According to the utility model, the seal ring and the seal ring accommodating groove in which the seal ring is arranged are arranged at the edge of the shell, so that a gap between the shell and the base plate is filled, and the motor drive controller has good sealing performance and can play very good waterproof and dustproof roles.
Description
Technical field
The utility model relates to a kind of controller, especially a kind of motor drive controller.
Background technology
Motor drive controller is all at high temperature; Moist; The environment of many dirt is work down, therefore necessarily require controller can waterproof with dustproof, the primary structure of existing controller is made up of plastic shell, base plate and circuit board assemblies etc.; The requirement of water proof and dust proof is mainly by the completion that closely cooperates between plastic shell and the base plate; Yet plastic shell and base plate all are hard cooperations, and its sealing effectiveness is difficult to reach perfect condition, and in plastic shell and base plate engagement process under the two situation such as all might deform; Make it produce slit and cause enterings controllers inside such as dust, humid air, water and cause product quality problem, make it be difficult to reach the effect of water proof and dust proof.
Summary of the invention
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists, and provides a kind of good seal performance, water proof and dust proof effective, can guarantee the motor drive controller of board quality.
The technical scheme of the utility model: a kind of motor drive controller; Comprise close-connected shell and base plate and circuit board assemblies in the enclosure is set; Said shell edge is provided with the sealing ring holding tank; Be provided with sealing ring in the said sealing ring holding tank, said shell and base plate are through the sealing ring sealing.
Preferably, be provided with the post that is threaded around the said enclosure, said base plate is provided with the screwed hole of matching thread joint pin, and said shell is connected through screw with base plate.
Preferably, said circuit board assemblies comprises circuit board, and said enclosure is provided with the circuit board installing hole of mating circuit plate.
Preferably, said sealing ring is circular or strip.
The utility model is provided with sealing ring and the sealing ring holding tank that sealing ring is installed at shell edge, makes that the slit between shell and the base plate is all clogged, and makes its good seal performance, can play good water proof and dust proof effect.
