Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the accompanying drawings.

Referring to fig. 1 to 5, the utility model provides a coil connecting terminal installs on coil skeleton 1, include: first binding post 2 and second binding post 3 are provided with terminal block 101 on the coil skeleton 1, and second binding post 3 fixed mounting is on terminal block 101, and second binding post 3 is used for being connected with the enameled wire on the coil skeleton 1, and first binding post 2 pegs graft on second binding post 3.

Referring to fig. 2 and 3, the second connection terminal 3 includes a plug tab 301, the bottom of the plug tab 301 is fixedly mounted on the connection terminal base 101, one side of the top of the plug tab 301 extends upwards to form a connection terminal 302, one side of the connection terminal 302 is provided with a sawtooth groove 3021, and an enameled wire terminal is wound on the sawtooth groove 3021.

Referring to fig. 2 and 4, the upper portion of the first connection terminal 2 is a plugging end for connecting an external component, the bottom of the first connection terminal 2 is provided with a clamping portion 201 integrated with the plugging end, the clamping portion 201 includes two clamping plates 2011 which are symmetrically arranged and have elastic deformation, the two clamping plates 2011 are arranged in parallel and spaced, a clamping gap 202 is formed between the two clamping plates 2011, and the upper end portion of the plugging piece 301 is plugged in the clamping gap 202.
