And the protective means is composed of a protective cover and a fixing structure which is inserted and fixed in a manner to be inserted into the protective cover and which has a power connector and a bus A brushless motor with a power connection protection of the bar is provided.
Description
The present invention relates to a brushless motor having a power connector and a power supply connection function of a bus bar, and more particularly, to a brushless motor having a power connector connected between a power terminal of a power connector for applying power to the motor and a connection terminal of a bus bar The parts electrically connected to the solder are forcibly protected so that faulty contact and short circuit between the power terminal and the connection terminal can be prevented in the event of shock transmission from the outside or severe environmental conditions.
Background Art [0002] A brushless motor widely used in general has a configuration in which a power side power connector for applying external power to a motor side stator and a stator made up of an assembly of divided cores are arranged on the motor side. And is connected in parallel with a lead wire between the power terminal of the power connector and the connection terminal of the stator.

If a connection failure or a short circuit occurs as described above, the operation may not be performed or the operation may suddenly stop during operation. In the case of the automobile, if the associated device does not operate or suddenly stops while driving, Which can lead to dangerous situations.
The present invention has been developed in order to solve the above problems, and by forcibly protecting a portion electrically connected to a solder between a power terminal of a power connector for applying power to the motor and a connection terminal of a stator disposed on the motor side, And it is an object of the present invention to provide a brushless motor having a power connector and a protection function for power supply connection of a bus bar to prevent a contact failure and a short circuit between a power terminal and a connection terminal under impact transmission or harsh environmental conditions.
In order to achieve the above-mentioned object, the present invention provides a power connector in which a contact portion of a power terminal drawn out from an upper surface of a power connector is bent in a raised state, and a three- And a protective cover is attached to the contact connecting portion where the contact portion and the three-phase connecting terminal are connected by solder so that the contact connecting portion is not exposed. The protecting means includes a protective cover, There is provided a brushless motor provided with a power connector and a power connection protection function of a bus bar, which is composed of a fixed structure to be inserted and fixed in a manner to be inserted into the fixed structure, .
The fixing structure is formed of a hollow structure that forms a through hole. The fixed structure includes a power connector, which is coupled in an insertion manner in which a contact connecting portion is inserted into the through hole, and a brushless A motor is provided.
