Card edge connector structure

A card edge connector structure, comprising:

• an insulating case;
• a terminal assembly configured in the insulating case, the terminal assembly further comprising:
• a first terminal set comprising a plurality of first signal terminals, at least one first grounding terminal and a first terminal fixing component, the first terminal fixing component comprising at least one first groove, the first signal terminals and the at least one first grounding terminal being fixed by the first terminal fixing component and arranged in parallel, and the position of the at least one first groove of the first terminal fixing component being corresponding to that of the at least one first grounding terminal to expose a part of the at least one first grounding terminal out of the first terminal fixing component;
• and
• a second terminal set configured corresponding to the first terminal set, the second terminal set comprising a plurality of second signal terminals, at least one second grounding terminal and a second terminal fixing component, the second terminal fixing component comprising at least one second groove, the second signal terminals and the at least one second grounding terminal being fixed by the second terminal fixing component and arranged in parallel, and the position of the at least one second groove of the second terminal fixing component being corresponding to that of the at least one second grounding terminal to expose a part of the at least one second grounding terminal out of the second terminal fixing component;
• a first grounding sheet configured between the insulating case and the first terminal set, the first grounding sheet comprising at least one first elastic arm, the at least one first elastic arm being configured to contact the at least one first grounding terminal through the at least one first groove;
• and
• a second grounding sheet configured between the insulating case and the second terminal set, the second grounding sheet comprising at least one second elastic arm, the at least one second elastic arm being configured to contact the at least one second grounding terminal through the at least one second groove;
• wherein each of the first signal terminals, the second signal terminals, the at least one first grounding terminal and the at least one second grounding terminal comprises a fixed part and an elastic part, the fixed parts of the first signal terminals and the at least one first grounding terminal are fixed in the first terminal fixing component, and the fixed parts of the second signal terminals and the at least one second grounding terminal are fixed in the second terminal fixing component, and the elastic parts of the first signal terminals, the at least one first grounding terminal, the second signal terminals and the at least one second grounding terminal are extended upwardly from the first terminal fixing component and the second terminal fixing component respectively.
