Both sides of the lower electromagnetic interference component 31 are provided with locking blocks 34. Both sides of the lower terminal molding component 32 are provided with locking slots 35 for accommodating the locking blocks 34. Both sides of the hook 1 are provided with positioning blocks 12. Both sides of the housing 4 are provided with positioning grooves 41 for accommodating the positioning blocks 12.

[0026] The lower terminal molded part 32 protrudes into the groove 11 through the boss 33. The engaging connection between the boss 33 and the groove 11 not only increases the contact area but also provides a good limiting effect, preventing the lower terminal molded part 32 from loosening and falling off on the hook part 1. Furthermore, the lower electromagnetic interference part 31 protrudes into the slot 35 through the locking block 34, so that the lower electromagnetic interference part 31 is set on the lower terminal molded part 32, thereby assembling and fixing the lower terminal assembly 3 onto the hook part 1. The hook part 1 is set between the upper terminal assembly 2 and the lower terminal assembly 3, and plays the role of bearing the assembly. Further, the two sides of the hook part 1 are engaged and accommodated in the positioning groove 41 by the positioning blocks 12, thereby assembling and fixing the hook part 1 onto the housing 4, enhancing the assembly firmness of the upper terminal assembly 2, the hook part 1, the lower terminal assembly 3 and the housing 4. The above structural design can comprehensively improve the anti-loosening performance of the connection between various components.
