Abstract

A structure of a Brushless Direct Current (BLDC) motor includes a control board having an electric circuit therein, and a housing electrically connected to the control board. The housing includes a rotor having a permanent magnet, a stator in which a coil is wound, a protruding member protruding to one side of the housing, and a terminal electrically connected to the coil and disposed at the protruding member. The control board includes a socket electrically connected to the electric circuit and disposed at the control board. When the housing and the control board are coupled, the terminal and the socket come into contact with each other so as to be electrically connected to each other.

First claim

What is claimed is:

1. A structure of a Brushless Direct Current (BLDC) motor, comprising:
a control board having an electric circuit therein; and
a housing electrically connected to the control board, wherein:
the housing includes:
a rotor having a permanent magnet,
a stator in which a coil is wound,
a protruding member protruding to one side of the housing, and
a terminal electrically connected to the coil and disposed at the protruding member,

the control board includes a socket electrically connected to the electric circuit and disposed at the control board,
when the housing and the control board are coupled, the terminal and the socket come into contact with each other so as to be electrically connected to each other,
wherein the socket includes a second socket having a plate shape, vertically standing on a surface of the control board, and having a fitting hole;
the protruding member includes a second protruding member having one side edge disposed in the fitting hole of the second socket when the housing and the control board are coupled; and
the terminal includes a second terminal disposed at one side edge of the second protruding member to be disposed in the fitting hole of the second socket when the housing and the control board are coupled.

2. The structure of claim 1 , wherein:
the socket includes a first socket having a plate shape and horizontally disposed to be in parallel to a surface of the control board,
the protruding member includes a first protruding member which approaches the first socket when the housing and the control board are coupled, and
the terminal includes a first terminal disposed at the first protruding member to be in contact with the first socket when the housing and the control board are coupled, such that the first terminal is elastically deformable when the first terminal comes into contact with the first socket.

3. The structure of claim 2 , wherein an arc-shaped curved portion is disposed at an end of the first terminal.

4. The structure of claim 1 , wherein an enlarged hole is defined in the second socket to extend from the fitting hole such that a width of the fitting hole is elastically increased when the second terminal enters.

5. The structure of claim 1 , wherein the second terminal is attached in a mount hole concavely recessed in the second protruding member.
