The terminal structure 1 of the present utility model is mainly used for clamping an electronic component 2 having a plurality of leads 20, the terminal structure 1 mainly comprises a body 10, a plugging portion 12 and a clamping structure 14, wherein at least one side of the body 10 forms a clamping structure 100, the plugging portion 12 extends from one end of the body 10 and is used for clamping a circuit board 3 having a conductive hole 30, the plugging portion 12 defines a first pressing edge 120 and a second pressing edge 122 respectively connected with two ends of the first pressing edge 120, and an internal pressure space 124 is defined between the first pressing edge 120 and the second pressing edge 122. The clamping structure 14 extends from the other end of the body 10, and the clamping structure 14 includes two corresponding clamping arms 140, and each of the clamping arms 140 has a clamping space 142 for clamping and fixing one of the conductive pins 20 of the electronic component 2 formed on the corresponding side.

In addition, a stopping structure 16 is defined between the body 10 and the plug portion 12, and a plurality of interference structures 102 are defined on two corresponding sides of the body 10. The corresponding sides of the clamping arms 140 respectively define a first side wall 1400 between the body 10 and the clamping space 142 and a second side wall 1402 at the other end of the clamping space 142, and the distances between the first side walls 1400 are the same, so that when the lead 20 in the electronic component 2 needs to be clamped in the terminal structure 1, the lead 20 is guided to be close to the clamping space 142 by the inclined second side walls 1402, and then the terminal structure 1 is pushed to be clamped in the clamping space 142 to clamp the lead 20, and the clamping force of the lead 140 to the lead 20 can be improved due to the same distance between the first side walls 1400 of the clamping arms 140 of the connecting body 10, so that detachment caused by external influence is avoided.
