A plurality of terminals 11 are arranged in a row along a first direction L1, and an insulating structure 12 is attached to the plurality of terminals 11, thereby positioning the plurality of terminals 11 in the insulating structure 12 to form a fixed structure. A metal shell 14 covers the insulating structure 12 and the plurality of terminals 11 to form a space for mating with an electrical connector of an opponent, while strengthening the structure of the electromagnetically shielded enhanced female electrical connector 1. Moreover, the metal material can absorb electromagnetic waves, thus also achieving the effect of electromagnetic shielding. A plurality of terminals 11 are electrically connected to a circuit board P. In this embodiment, the first direction L1 is perpendicular to the circuit board P. Therefore, the plurality of terminals 11 are arranged in a direction perpendicular to the circuit board P. The insulation structure 12 and the metal casing 14 are arranged in an upright structure corresponding to the arrangement of the terminals 11.

A plurality of terminals 11 are formed from metal strip using a stamping process. Each terminal 11 includes an electrical connection portion 111, a mating portion 112, and a fixing portion 113. The fixing portion 113 is fixed to the insulation structure 12, the mating portion 112 mates with a terminal of a matching connector, and the electrical connection portion 111 is electrically connected to the circuit board 20.

The electromagnetically shielded enhanced female electrical connector 1 of this embodiment is a Universal Serial Bus (USB) electrical connector that conforms to the USB 3.0 specification.

Referring to Figure 3, the electrical connection portions 111 of a plurality of terminals 11 are arranged in a row, and the fixing portions 113 of a plurality of terminals 11 are also arranged in a row. The fixing portion 113 of the first ground terminal 11c is connected to the fixing portion 113 of the second ground terminal 11d to form an integrated structure, and the first ground terminal 11c and the second ground terminal 11d have a common electrical connection portion 111. The conventional signal terminal pair 11e is located between the integrated structure of the first ground terminal 11c and the second ground terminal 11 and the power terminal 11f. The width of the fixing portion 113 of the integrated structure of the first ground terminal 11c and the second ground terminal 11d is equal to the width of the fixing portion 113 of the power terminal 11f and is greater than the width of the fixing portions 113 of the other terminals 11. The width of the common electrical connection portion 111 of the first grounding terminal 11c and the second grounding terminal 11d is equal to the width of the electrical connection portion 111 of the power supply terminal 11f, and greater than the width of the electrical connection portions 111 of the other terminals 11. The electrical connection portions 111 and fixing portions 113 of the plurality of terminals 11, from top to bottom, are respectively a first high-frequency signal terminal pair 11a, an integrated structure of the first grounding terminal 11c and the second grounding terminal 11d, a conventional signal terminal pair 11e, a power supply terminal 11f, and a second high-frequency signal terminal pair 11b.

In this embodiment, the electrical connection 111 is a solder pin, soldered to the pad P1 of the circuit board P. The electrical connection 111 in this embodiment is arranged at equal intervals along the first direction L1. However, the invention is not limited to this; in other embodiments, the electrical connection may also be a pin, inserted into a through-hole of the circuit board, or a combination of solder pins and pins.

The connectors 112 of the plurality of terminals 11 are divided into a front row A and a rear row B according to the nine pins of the USB 3.0 specification. The connectors 112 in the front row A, from top to bottom, consist of a first high-frequency signal terminal pair 11a, a first ground terminal pair 11c, and a second high-frequency signal terminal pair 11b. The connectors 112 in the rear row B, from top to bottom, consist of a second ground terminal 11d, a standard signal terminal pair 11e, and a power terminal 11f.

A plurality of electrical connection portions 111 of terminals 11 are arranged in a row along a first direction L1, which is parallel to the surface of the circuit board P. The electrical connection portions 111 of the plurality of terminals 11 are soldered to solder pads P1 of the circuit board P.

For the electrical connection portions 111 and fixing portions 113 of the plurality of terminals 11, the electrical connection portions 111 and fixing portions 113 of the first high-frequency signal terminal pair 11a and the conventional signal terminal pair 11e are separated by an integrated electrical connection portion 111 and fixing portion 113 of the first ground terminal 11c and the second ground terminal 11d. The electrical connection portions 111 and fixing portions 113 of the second high-frequency signal terminal pair 11b and the conventional signal terminal pair 11e are separated by the electrical connection portion 111 and fixing portion 113 of the power terminal 11f. The electrical connection portion 111 and the fixing portion 113 of the first high-frequency signal terminal pair 11a and the second high-frequency signal terminal pair 11b are separated by the electrical connection portion 111 and the fixing portion 113 of the first ground terminal 11c, the second ground terminal 11d, the conventional signal terminal pair 11e, and the power terminal 11f. Furthermore, as mentioned above, in this embodiment, the width of the fixing portion 113 and the electrical connection portion 111 of the integrated structure of the first ground terminal 11c and the second terminal 11d is set to be larger than the width of the fixing portion 113 and the electrical connection portion 111 of the other terminals 11, and the width of the fixing portion 113 and the electrical connection portion 111 of the power terminal 11f is set to be larger than the width of the fixing portion 113 and the electrical connection portion 111 of the other terminals 11. Meanwhile, the distance between the electrical connection portion 111 of the conventional signal terminal pair 11e and the common electrical connection portion 111 of the adjacent first ground terminal 11c and second ground terminal 11d is greater than the distance between the electrical connection portion 111 of the first high-frequency signal terminal pair 11a and the common electrical connection portion 111 of the first ground terminal 11c and second ground terminal 11d. Furthermore, the distance between the electrical connection portion 111 of the conventional signal terminal pair 11e and the electrical connection portion 111 of the adjacent power terminal 11f is greater than the distance between the electrical connection portion 111 of the second high-frequency signal terminal pair 11b and the electrical connection portion 111 of the power terminal 11f. This provides a better electromagnetic shielding effect for the high-frequency signals of the first high-frequency signal terminal pair 11a and the second high-frequency signal terminal pair 11b.

Referring to Figure 4, the insulation structure 12 is bonded to a plurality of terminals 11 via an insert molding process. The insulation structure 12 of this embodiment includes a tongue portion 121 and a base portion 122. The tongue portion 121 has three first openings 1211 and five second openings 1212. The mating portions 112 of the terminals 11 in the front row A are correspondingly disposed in the second openings 1212, and the mating portions 112 of the terminals 11 in the rear row B are correspondingly disposed in the first openings 1211. Through the first openings 1211 and second openings 1212, the mating portions 112 of the terminals 11 in the front row A and the rear row B can be exposed from the tongue portion 121 and contact the terminals of the corresponding handheld connector.

The tongue portion 121 is connected to the base 122. The electrical connection portion 111 of the terminal 11 protrudes from the base 122 and abuts against the solder pad P1 of the circuit board P, so as to allow the electrical connection portion 111 to be soldered to the solder pad P1.

Please refer to Figures 5 and 6. The metal shell 14 is disposed on the insulation structure 12, and the base 122 of the insulation structure 12 supports the metal shell 14. The metal shell 14 of this embodiment has a first opening 141 and a second opening 142. The first opening 141 serves as a mating interface for connecting with the power connector. The mating portion 112 of the terminal 11 is disposed near the first opening 141, and the metal shell 14 forms a mating space corresponding to the position of the tongue portion 121 for the power connector to be inserted. The terminals of the power connector are made to contact the terminals 11 of the electromagnetically shielded enhanced female power connector 1 of this embodiment to form an electrical connection and transmit signals. The second opening 142 exposes the base 122 of the insulation structure 12, allowing the electrical connection portion 111 of the terminal 11 to abut against the solder pad P1 of the circuit board P.

In addition to forming the mating space with the counterpart electrical connector, the metal shell 14 covers the base 122 of the insulation structure 12, thereby strengthening the overall structural strength of the electromagnetically shielded female electrical connector 1. Furthermore, the metal shell 14 can absorb electromagnetic waves and also form external electromagnetic shielding for the terminals 11, preventing noise generation in the signals transmitted at the terminals 11.

The metal housing 14 is inserted into the through hole P2 of the circuit board P via the pin 143, thereby fixing the electromagnetically shielded female electrical connector 1 to the circuit board P.

The electromagnetically shielded enhanced female electrical connector of the present invention has terminals arranged in a row along a first direction. The fixed portion of the first grounding terminal is connected to the fixed portion of the second grounding terminal, so that the first grounding terminal and the second grounding terminal form an integrated structure, and the first grounding terminal and the second grounding terminal have a common electrical connection portion. Furthermore, the first high-frequency signal terminal pair and the second high-frequency signal terminal pair have fixed and electrical connection portions for their fixing parts and electrical connections, and the first high-frequency signal terminal pair and the conventional signal terminal pair have fixed and electrical connection portions and electrical connections for their fixing parts and electrical connections, or/and the second high-frequency signal terminal pair and the conventional signal terminal pair have fixed and electrical connection portions for their fixing parts and electrical connections, respectively.
