상기한 바와 같이 본 발명은 단자결합홈(104)에 삽입된 결합편(202) 및 절곡된 결합편(202)을 타발하여 코킹부(106)에 결합편(202)이 개입되게 함으로써, 터미널 단자(200)에 전후방으로 힘이 가해지더라도 탈락이 방지되며, 특히, 고정공(108)에 삽입된 고정돌기(204)를 하향타발함으로써, 고정돌기(204)가 'T'자형 결합구조를 가지게 함으로써, 적어도 두 개의 단자결합홈(104)과 결합편(202)에 의한 결합구조에서 'T'자형 결합구조를 보강할 수 있게 되어 보다 안정적이고 강력한 결합구조를 확보할 수 있게 된다.As described above, the present invention punches out the coupling piece 202 and the bent coupling piece 202 inserted into the terminal coupling groove 104 so that the coupling piece 202 intervenes in the caulking portion 106, thereby forming a terminal terminal. Even if force is applied to (200) forward and backward, it is prevented from falling off. In particular, by punching downward the fixing protrusion 204 inserted into the fixing hole 108, the fixing protrusion 204 has a 'T'-shaped coupling structure. , it is possible to reinforce the 'T' shaped coupling structure in the coupling structure by at least two terminal coupling grooves 104 and the coupling piece 202, thereby ensuring a more stable and strong coupling structure.
