The metal shell 14 covers the insulating structure 12 and the plurality of terminals 11 to form a space for docking with the opponent's electrical connector, while strengthening the structure of the vertical female end electrical connector 1, and the metal material can absorb electromagnetic waves, so it can also play an electromagnetic shielding effect. The plurality of terminals 11 are electrically connected to a circuit board P. The first direction L1 of this embodiment is perpendicular to the circuit board P, so the plurality of terminals 11 are arranged in a direction perpendicular to the circuit board P, and the insulating structure 12 and the metal shell 14 form an upright structure corresponding to the arrangement of the terminals 11.

[0023] The plurality of terminals 11 are formed by stamping process with metal strips, and each terminal 11 includes an electrical connection portion 111, a docking portion 112, and a fixing portion 113. The fixing portion 113 is fixed to the insulating structure 12, the docking portion 112 docks with a terminal of a pair of connectors, and the electrical connection portion 111 is electrically connected to the circuit board 20.

[0024] The vertical female electrical connector 1 of this embodiment is a universal serial bus (USB) electrical connector that complies with the USB 3.0 specification. The terminal 11 includes a first high-frequency signal terminal pair 11a, a second high-frequency signal terminal pair 11b, a first grounding terminal 11c, a second grounding terminal 11d, a conventional signal terminal pair 11e, and a power terminal 11f.

[0025] See also Figure 3 , the electrical connection parts 111 of the plurality of terminals 11 are arranged in a row, and the fixing parts 113 of the plurality of terminals 11 are arranged in a row. The fixing part 113 of the first grounding terminal 11c is connected to the fixing part 113 of the second grounding terminal 11d to form an integrated structure, and the first grounding terminal 11c and the second grounding terminal 11d have a common electrical connection part 111. The conventional signal terminal pair 11e is located as a whole between the integrated structure of the first grounding terminal 11c and the second grounding terminal 11 and the power terminal 11f. The width of the integrated fixing part 113 of the first grounding terminal 11c and the second grounding terminal 11d is equal to the width of the fixing part 113 of the power terminal 11f, and is greater than the width of the fixing part 113 of the other terminals 11. The width of the common electrical connection portion 111 of the first ground terminal 11c and the second ground terminal 11d is equal to the width of the electrical connection portion 111 of the power terminal 11f, and is greater than the width of the electrical connection portions 111 of the other terminals 11. The electrical connection portions 111 and the fixed portions 113 of the plurality of terminals 11 are, from top to bottom, the first high-frequency signal terminal pair 11a, the integrated structure of the first ground terminal 11c and the second ground terminal 11d, the conventional signal terminal pair 11e, the power terminal 11f, and the second high-frequency signal terminal pair 11b.

[0026] The electrical connection portion 111 of this embodiment is a solder foot, which is soldered to the solder pad P1 of the circuit board P. The electrical connection portions 111 of this embodiment are arranged along the first direction L1 at equal intervals. However, the present invention is not limited thereto. In other embodiments, the electrical connection portion may also be a pin, which is plugged into the through hole of the circuit board, or a combination of a solder foot and a pin.

[0027] The docking parts 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 docking parts 112 of the front row A are respectively the first high-frequency signal terminal pair 11a, the first ground terminal 11c and the second high-frequency signal terminal pair 11b from top to bottom. The docking parts 112 of the rear row B are respectively the second ground terminal 11d, the normal signal terminal pair 11e and the power terminal 11f from top to bottom.

[0028] The fixing portions 113 of the plurality of terminals 11 are bent toward one side of the vertical female electrical connector 1, and the bending lengths are different, so that the electrical connection portions 111 of the plurality of terminals 11 are arranged in a row along a second direction L2. The second direction L2 is perpendicular to the first direction L1 and the second direction L2 is parallel to the surface of the circuit board P. Therefore, the electrical connection portions 111 of the plurality of terminals 11 are soldered to the solder pads P1 of the circuit board P.

[0029] For the electrical connection parts 111 and the fixed parts 113 of the plurality of terminals 11, the electrical connection parts 111 and the fixed parts 113 of the first high-frequency signal terminal pair 11a and the conventional signal terminal pair 11e are separated by the electrical connection parts 111 and the fixed parts 113 of the integrated structure of the first ground terminal 11c and the second ground terminal 11d. The electrical connection parts 111 and the fixed parts 113 of the second high-frequency signal terminal pair 11b and the conventional signal terminal pair 11e are separated by the electrical connection parts 111 and the fixed parts 113 of the power terminal 11f. The electrical connection parts 111 and the fixed parts 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 parts 111 and the fixed parts 113 of the first ground terminal 11c, the second ground terminal 11d, the conventional signal terminal pair 11e, and the power terminal 11f. In addition, as mentioned above, the width of the fixing portion 113 and the electrical connection portion 111 of the integrated structure of the first grounding terminal 11c and the second grounding terminal 11d of this embodiment 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, thereby forming 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.

[0030] See also Figure 4 , the insulating structure 12 is combined with a plurality of terminals 11 by an insert molding process. The insulating structure 12 of the present embodiment includes a tongue portion 121 and a base portion 122. The tongue portion 121 has three first through-hole portions 1211 and five second through-hole portions 1212. The mating portions 112 of the terminals 11 of the front row A are correspondingly disposed in the second through-hole portions 1212, and the mating portions 112 of the terminals 11 of the rear row B are correspondingly disposed in the first through-hole portions 1211. Through the first through-hole portions 1211 and the second through-hole portions 1212, the mating portions 112 of the terminals 11 of the front row A and the mating portions 112 of the terminals 11 of the rear row B can be exposed from the tongue portion 121 and contact the terminals of the counterpart electrical connector.

[0031] The base 122 is generally trapezoidal, and includes a connection surface 1221, a mounting surface 1222, and a support inclined surface 1223. The tongue portion 121 is connected to the connection surface 1221 of the base 122, and the electrical connection portion 111 of the terminal 11 protrudes from the mounting surface 1222. The mounting surface 1222 abuts against the circuit board P, and at the same time, the electrical connection portion 111 of the terminal 11 abuts against the soldering pad P1 of the circuit board P, so that the electrical connection portion 111 is soldered to the soldering pad P1. The connection surface 1221 and the mounting surface 1222 are perpendicular to each other, so the extension direction of the docking portion 112 of the terminal 11 provided on the tongue portion 121 and the extension direction of the electrical connection portion 111 of the terminal 11 protruding from the mounting surface 1222 are orthogonal to each other. The support inclined surface 1223 is connected to the connection surface 1221 and the mounting surface 1222, and is used to support the metal shell 14.

[0032] See also Figure 5 and Figure 6 The metal shell 14 is disposed on the insulating structure 12, and the load-bearing inclined surface 1223 of the base 122 of the insulating 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 docking interface for docking with the opponent electrical connector. The docking portion 112 of the terminal 11 is disposed near the first opening 141, and the metal shell 14 forms a docking space corresponding to the position of the tongue portion 121 for the opponent electrical connector to be inserted, and the terminal of the opponent electrical connector is contacted with the terminal 11 of the vertical female electrical connector 1 of this embodiment to form an electrical connection and transmit signals. The second opening 142 is exposed as the mounting surface 1222 of the base 122 of the insulating structure 12, so that the electrical connection portion 111 of the terminal 11 can abut against the solder pad P1 of the circuit board P.

[0033] In addition to forming a docking space with the opponent's electrical connector, the metal shell 14 is wrapped around the base 122 of the insulating structure 12, which can enhance the overall structural strength of the vertical female electrical connector 1. The metal shell 14 can absorb electromagnetic waves and form an external electromagnetic shielding for the terminal 11 to avoid noise generated by the signal transmitted at the terminal 11.

[0034] The metal shell 14 is inserted into the through hole P2 of the circuit board P via the plug pins 143 , so that the vertical female electrical connector 1 is fixed to the circuit board P.

[0035] The vertical female end electrical connector of the present invention is arranged in a row along the first direction through the terminals. 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. And the fixed portion and the electrical connection portion between the first high-frequency signal terminal pair and the second high-frequency signal terminal pair, between the fixed portion and the electrical connection portion between the first high-frequency signal terminal pair and the conventional signal terminal pair, or / between the fixed portion and the electrical connection portion between the second high-frequency signal terminal pair and the conventional signal terminal pair have the fixed portion and the electrical connection portion of the first grounding terminal, the second grounding terminal or the power supply terminal, so that the first high-frequency signal terminal pair and the conventional signal terminal pair, the second high-frequency signal terminal pair and the conventional signal terminal pair, and the first high-frequency signal terminal pair and the second high-frequency signal terminal pair can have better electromagnetic shielding, prevent cross talk, and avoid noise and signal distortion.
