Detailed Description
Referring to fig. 1-3, the motor with the novel welding terminal provided by the utility model comprises a motor body 1, a welding terminal 2, an end cover 3 and a circuit board 4, wherein the end cover 3 is fixedly arranged at one end of the motor body 1, the circuit board 4 is fixedly arranged on the outer wall of a bearing cavity 32 on the end cover 3, the welding terminal 2 is arranged on the motor body 1 and is electrically connected with the motor body 1, the top of the welding terminal 2 is narrowed towards the vertical center line direction of the welding terminal to form a welding part 22, and the welding part 22 sequentially passes through a first through groove 31 formed in the end cover 3 and a second through groove 41 formed in the circuit board 4 and then is welded with the circuit board 4.
The height between the top of the welding terminal 2 and the end cover 3 is greater than the sum of the height of the bearing chamber 32 and the thickness of the circuit board 4, so that the welding part 22 of the welding terminal 2 can penetrate through the circuit board 4 and protrude out of the circuit board 4, thereby facilitating the welding.
In the above embodiment, the soldering terminal 2 is plate-shaped, the soldering terminal 2 is adapted to be inserted into the second through groove 41 on the circuit board 4, and the soldering tin after heating and melting is prevented from leaking through the original terminal hole when the soldering terminal 2 is soldered to the circuit board 4 because the soldering terminal 2 is plate-shaped and the original terminal hole is eliminated.
In the prior art, when the circuit board 4 is welded to the welding terminal 2, the width of each part of the welding terminal 2 is the same, so that when the circuit board 4 is welded, the welding part of the circuit board 4 is inclined due to the stress, and the welding is affected.
It should be further noted that the height of the support portion 21 of the welding terminal 2 at the upper portion of the end cap 3 is equal to the height of the bearing chamber 32.
In order to facilitate the fitting of the circuit board 4 outside the soldering terminal 2, the tip of the soldering portion 22 has a first chamfer.
In order to facilitate the fitting of the end cap 3 to the outside of the welding terminal 2, the tip of the supporting portion 21 has a second chamfer.
The circuit board 4 is provided with a rotating shaft hole for the rotating shaft of the motor body 1 to pass through.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
