[0018] like Figures 1 to 4As shown, one embodiment of the present invention provides a connector structure, including an insulating shell 1 and a terminal body 2; the insulating shell 1 is provided with a receiving groove 11 and a support arm 12 located in the receiving groove 11; The terminal body 2 includes a first side plate 21, a second side plate 22, a first bending arm 23, and a second bending arm 24. The first side of the first side plate 21 and the first side of the second side plate 22 are both connected to the first bending arm 23, and the second side of the first side plate 21 and the second side of the second side plate 22 are both connected to the second bending arm 24. An internal space is provided between the first side plate 21 and the second side plate 22. The first side plate 21 is provided with a first elastic contact plate 211 and a second elastic contact plate 212 spaced apart, and the second side plate 22 is provided with a third elastic contact plate 221 and a fourth elastic contact plate 222 spaced apart; a first insertion hole 25 is provided between the first elastic contact plate 211 and the third elastic contact plate 221, and a second insertion hole 26 is provided between the second elastic contact plate 212 and the fourth elastic contact plate 222. The first side of the first side plate 21 and the first side of the second side plate 22 are both provided with first locking teeth 213; the second side of the first side plate 21 and the second side of the second side plate 22 are both provided with second locking teeth 223. The terminal body 2 is installed in the receiving groove 11, the support arm 12 is inserted into the internal space, and the opposite sides of the support arm 12 abut against the first side plate 21 and the second side plate 22 respectively, and the first locking tooth 213 and the second locking tooth 223 respectively engage with the opposite two inner side walls of the receiving groove 11.

[0019] Wherein, the first side and the second side of the first side plate 21 are the left and right sides of the first side plate 21, respectively; the first side and the second side of the second side plate 22 are the left and right sides of the second side plate 22, respectively; the first elastic contact plate 211 and the second elastic contact plate 212 are spaced apart at the upper end of the first side plate 21, and the third elastic contact plate 221 and the fourth elastic contact plate 222 are spaced apart at the upper end of the second side plate 22; the support arm 12 is disposed at the top of the receiving groove 11.

[0020] Specifically, the external first plug terminal can be inserted into the first socket 25, and the first elastic contact plate 211 and the third elastic contact plate 221 can squeeze the first plug terminal from opposite sides; the external second plug terminal can be inserted into the second socket 26, and the second elastic contact plate 212 and the fourth elastic contact plate 222 can squeeze the second plug terminal from opposite sides.

[0021] In this invention, the terminal body 2 is installed in the receiving groove 11. The support arm 12 at the bottom of the receiving groove 11 can be inserted into the internal space between the first side plate 21 and the second side plate 22. Thus, the support arm 12 can open the first side plate 21 and the second side plate 22 from the inside. The side of the first side plate 21 away from the support arm 12 abuts against the inner wall of the receiving groove 11, and the end of the second side plate 22 away from the support arm 12 abuts against the inner wall of the receiving groove 11, thereby ensuring the stability of the receiving groove 11. Furthermore, both the first side plate 21 and the second side plate 22 have spaced-apart first locking teeth 213 on their first sides and spaced-apart second locking teeth 223 on their second sides. The first locking teeth 213 and the second locking teeth 223 respectively engage with the two opposite inner sidewalls of the receiving groove 11. During the insertion and removal of the external plug from the connector structure, the first locking teeth 213 and the second locking teeth 223 can prevent the terminal body 2 from disengaging from the receiving groove 11, thus preventing loosening between the terminal body 2 and the insulating shell 1 and ensuring the stability of the connector structure during insertion and removal. In addition, the first locking teeth 213 and the second locking teeth 223 are respectively located on opposite sides of the first side plate 21 and the second side plate 22, making both the first side plate 21 and the second side plate 22 complete panels. This increases the contact area between the support arm 12 and the first side plate 21 and the second side plate 22, making the terminal body 2 less prone to deformation and improving the stability of the connector structure. Furthermore, this connector has fewer structural components, a simple structure, low cost, and is easy to assemble.

The third elastic contact plate 221 is disposed on the first panel 214, and the fourth elastic contact plate 222 is disposed on the second panel 215. The first panel 214, the first bending arm 23, the first side plate 21, the second bending arm 24, and the second panel 215 are integrally formed parts; The first panel 214 has spaced slots 217 on the side away from the first bending arm 23, and the second panel 215 has spaced snap-fit ​​parts 216 on the side away from the second bending arm 24.
