Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] see Figure 1 to Figure 3 , a connection terminal of an automotive motor controller shown in the figure is made of a material with certain elasticity, such as copper material with conductive function, which includes a phase line welding part 10, a pad welding part 20 and a connecting part 30 , the connecting portion 30 connects the phase line welding portion 10 and the land welding portion 20 as a whole.
[0021] The pad welding portion 20 extends parallel to the pad 41 on the PCB 40 . The phase wire welding portion 10 extends along a direction substantially parallel to the phase wire outlet end 50 of the motor coil.
[0022] The connection part 30 is L-shaped, and is composed of a straight section 31 parallel to the pad welding part 20 and a vertical section 32 substantially parallel to the phase line welding part 10, and one end of t...

The invention discloses a connecting terminal, and the connecting terminal is made of a material with certain elasticity, and is characterized in that the connecting terminal comprises a phase line welding part welded with a phase line outgoing end of a motor coil; a bonding pad welding part which is welded with a bonding pad on the PCB; the connecting part is used for connecting the phase line welding part and the bonding pad welding part into a whole, the connecting part is L-shaped, the connecting part and the bonding pad connecting part form a U shape, and the connecting part has certain elasticity. According to the invention, the connecting terminal welded with the phase line outgoing end of the motor coil is additionally arranged on the PCB, so the stress caused by the direct connection between the phase line and the PCB is reduced, and the possibility of poor contact between the phase line outgoing line and the PCB outgoing line is greatly reduced in the use process. In addition, the connecting terminal is welded with the phase line outgoing end of the motor coil through the convex rib, so that firm welding between the connecting terminal and the phase line outgoing end of the motor coil is ensured.
Description
technical field [0001] The invention relates to the technical field of motor controllers for automobile cooling fans, in particular to a connection terminal for an automobile motor controller. Background technique [0002] At present, the phase wire in the motor coil is directly connected to the PCB board, and there is stress at the connection. During use, it is easy to cause cracks or even disconnection at the welding point, which affects the normal movement of the motor. At the same time, it is easy to cause heat to burn the PCB board due to poor contact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a connection terminal of an automotive motor controller for the above-mentioned shortcomings of the direct welding of the motor phase wire and the PCB board in the prior art, through which the phase wire of the motor is connected to the PCB board Welding, to solve the deficiencies in the above-mentioned prior ar...
