Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following detailed description is given with reference to the embodiments and the accompanying drawings.

As shown in fig. 1 to 3, the motor bobbin 100 of the present invention includes a bobbin 1 and a motor connection terminal 2, wherein the bobbin 1 has a connection leg 11, and the connection leg 11 has a connection groove 111. Motor connecting terminal 2 includes terminal body 21, the one end of terminal body 21 is equipped with connector 22, the other end of terminal body 21 is equipped with fixed head 23, the left and right both sides edge of fixed head 23 is equipped with a plurality of tooth portions 231 outwards protrudingly, one of them the oblique lug 232 of outwards salient of preceding, the rear side of fixed head 23, the thickness of oblique lug 232 is followed fixed head 23 to connector 22 direction is crescent. The fixing head 23 of the motor connecting terminal 2 is inserted into the connecting groove 111, so that the tooth portion 231 is clamped at the edge of the connecting groove 111, and the inclined protrusion 232 abuts against the inner side surface of the connecting groove 111.

Referring to fig. 3, the left and right side edges of the middle portion of the terminal body 21 protrude outward to form wing portions 211. The wing portions 211 may limit or position the connection terminals 2, thereby improving convenience of assembly. The side of the terminal main body 21 on the same side as the inclined protrusion 232 is provided with a connecting portion 212 integrally formed with the terminal main body 21. Specifically, an elongated through hole 213 is punched in the middle of the terminal main body 21, one end of the strip corresponding to the elongated through hole 213 is suspended, and the other end of the strip is connected to the terminal main body 21 and bent and protruded toward one side of the inclined protrusion 232, so as to form the connecting portion 212. The teeth 231 are arranged continuously. This makes it possible to increase the number of the tooth portions 231 of the fixing head 23 within a limited length, thereby improving the pulling force of the connection terminal 2. Specifically, the tooth 231 has an upper plane 231a and an inclined side 231b, wherein the inclined side 231b of one tooth 231 is connected to the upper plane 231a of the adjacent tooth 231.
