The first contact point is defined on the side edge of the body and in the vicinity of the pin, and the second contact point is defined on the body between the two sandwiching members.

A third object of the present invention is to provide a card edge connector. That is, the first grounding sheet is further coupled to the electrode plate in order to electrically connect to the first contact point and expand the grounding area.

A fourth object of the present invention is to provide a card edge connector. That is, the second grounding sheet is further coupled to the electrode plate in order to electrically connect to the second contact point and expand the grounding area.

A fifth object of the present invention is to provide a card edge connector. That is, the electrode plate forms a grounding circuit with the first grounding sheet and the second grounding sheet, optimizes the high frequency performance, and improves the crosstalk problem.

A sixth object of the present invention is to provide a high frequency grounded terminal structure that optimizes high frequency performance and improves the problem of crosstalk.

In order to solve the above problems, the card edge connector of a certain aspect of the present invention can connect the first printed circuit board and the second printed circuit board. The first printed circuit board and the second printed circuit board provide power, ground, and signal, respectively. The card edge connector includes a power supply unit and a signal unit. The power supply unit can connect the power supply and the ground of the first printed circuit board and the second printed circuit board, respectively. The signal unit includes a plurality of electrode plates, a plurality of signal terminals, and a plurality of insulators. These signal terminals are located between two adjacent electrode plates. These signal terminals can receive the signal of the second printed circuit board. These insulators fix the signal terminals between two adjacent electrode plates. Each of these electrode plates further includes a main body, a holding member, a pin, a first contact point, and a second contact point. The body is electrically connected to a holding member, a pin, a first contact point, and a second contact point.

The first printed circuit board and the second printed circuit board provide power, ground, and signal, respectively. The high-frequency ground terminal structure includes a main body, a plurality of holding members, pins, a first contact point, and a second contact point. These sandwiching members extend in the first direction from the main body, can sandwich the second printed circuit board, and receive the signal of the second printed circuit board. The pins extend in the second direction from the body and are connected to the ground or power supply of the first printed circuit board. The first contact point is defined on the side edge of the main body and near the pin. The second contact point is defined in the main body between these sandwiching members.

Compared with conventional connectors, the high frequency grounded terminal structure according to the present invention realizes the advantages of high frequency and high speed transmission by providing a large area main body, holding member, and pin. In another embodiment, the body further selectively superimposes and connects the first and / or second ground sheets to the body to form a ground circuit, optimizing high frequency performance and improving crosstalk / crosstalk problems. doing. That is, since the spatial distance between the two signal lines is short, unnecessary inductance and capacitive coupling are generated between the two signal lines, which solves the problem of signal interference.
