By positioning the cross arm 51 in the groove of the positioning block 43, the cross arm 51 is separated from the pins of each terminal of the signal terminal set 4 by a distance to avoid contact and short circuit.

[0070] In this embodiment, in more detail, the two sides of the insulating body 2 are provided with assembly parts 25, and the assembly parts 25 are formed into a slot type on the two sides of the insulating body 2.

Fig. 9 2 is a schematic diagram of the appearance of the assembly in some embodiments of the present invention. In this embodiment, the assembly method is, for example but not limited to: first install the power terminal set 3 in the terminal slot 22, then insert the signal terminal set 4 into the terminal slot 22, and finally insert the hook 5 into the two sides of the insulating body 2, but is not limited to this. In some implementations, the assembly method can be: first install the power terminal set 3 in the terminal slot 22, then insert the signal terminal set 4 into the terminal slot 22, and finally insert the hook 5 into the two sides of the insulating body 2.

[0073] In this embodiment, in more detail, the shielding shell 1 is a hollow shell, and the shielding shell 1 has a storage groove inside. The shielding shell 1 can be a one-piece shell or a combination of a multi-piece shell structure. In addition, a circular arc or rectangular connection frame opening is formed on one side of the shielding shell 1, and the connection frame opening is connected to the storage groove.

[0074] In this embodiment, to be more specific, the insulating body 2 is mainly composed of a base, an annular wall structure, a slot 21 and a mounting groove. Here, the base, the annular wall structure, the slot 21 and the mounting groove are formed by injection molding, and a first plate body and a second plate body are formed above and below the annular wall structure. The annular wall structure extends from one side of the base, and the mounting groove is formed on the other side of the base, that is, a U-shaped mounting groove is formed on the other side of the base.

[0075] In this embodiment, in more detail, the base of the insulating body 2 includes a plurality of terminal slots 22, which penetrate the inner wall of the mounting groove, and are connected to the slot 21, and the plurality of terminal slots 22 provide a plurality of terminals for plug-in assembly. In addition, the slot 21 is located between the first plate body and the second plate body of the annular wall structure.

[0076] Reference Figure 1 to Figure 2 , Figure 1 It is a schematic diagram of the appearance. Figure 2 The power terminal group 3 is a schematic diagram of a plurality of elastic and integrated first contact segments 31 and a plurality of second contact segments 32. The fixing piece 33 is arranged on the base of the insulating body 2, and the width of the fixing piece 33 is greater than the width of the first contact segment 31 or the second contact segment 32. The first contact segment 31 and the second contact segment 32 are aligned with the terminal slot 22 and inserted into the slot 21, and the front end of the fixing piece 33 can abut against the inner wall surface of the terminal slot 22 (the stopper 23 of the inner wall of the terminal slot 22).

[0077] The first contact segment 31 and the second contact segment 32 extend from the upper and lower ends of one side of the fixing plate 33 to the slot 21, and the front ends of the first contact segment 31 and the second contact segment 32 provide contact with the terminals of the socket electrical connector. The first contact segment 31, the second contact segment 32 and the fixing plate 33 of the power terminal group 3 form a clip-type structure, that is, the first contact segment 31, the second contact segment 32 and the fixing plate 33 have a C-shaped appearance when viewed from the side, such as a harpoon appearance. In addition, the first contact segment 31 and the second contact segment 32 extend from the upper and lower ends of one side of the fixing plate 33 and are located on the lower surface of the first plate body and the upper surface of the second plate body, that is, the first contact segment 31 and the second contact segment 32 form upper and lower rows of terminals located in the slot 21.

[0078] The front sides of the first contact segment 31 and the second contact segment 32 are symmetrical, inclined and close to each other, and the width of the clamping area between the first contact segment 31 and the second contact segment 32 gradually decreases from the inside to the opening. When the plug electrical connector 100 is inserted into the socket electrical connector, the upper and lower surfaces of the tongue plate of the socket electrical connector first contact the curved surface of the first contact segment 31 and the second contact segment 32 that are close to each other, so that the first contact segment 31 and the second contact segment 32 have a higher clamping force due to the design of being inclined to each other, that is, because the distance between the first contact segment 31 and the second contact segment 32 that are designed to be inclined and close to each other is smaller than the width of the tongue plate, when the tongue plate is inserted between the first contact segment 31 and the second contact segment 32 and pushes the first contact segment 31 and the second contact segment 32 apart, the first contact segment 31 and the second contact segment 32 rebound to increase the clamping force of the tongue plate.

[0079] From the front view of each terminal of the power terminal group 3 (such as Figure 7 As shown in the figure, from the right to the left are the elastic ground terminal (Gnd), the first elastic power terminal (Power / VBUS), the second elastic power terminal (Power / VBUS), and the elastic ground terminal (Gnd) on the far left.

[0080] The plug electrical connector 100 is further provided with a plurality of hooks 5, each of which is located on both sides of the insulating body 2. The hooks 5 and the insulating body 2 can be combined by insert-molding or by assembly, that is, the assembly method is to provide through slots on both sides of the insulating body 2, and the hooks 5 are installed in the through slots for positioning. The plurality of hooks 5 are mainly composed of a plurality of protruding hook portions and a plurality of protruding contact portions. The plurality of protruding hook portions are fixed on both sides of the insulating body 2, and the outer sides of the plurality of protruding hook portions contact the inner wall surface of the shielding shell 1. The plurality of protruding contact portions extend from the front side of the protruding hook portions and extend into both sides of the slot 21. When the plug electrical connector 100 is plugged into the inside of the socket electrical connector, the buckle springs on both sides of the socket electrical connector will contact the plurality of protruding contact portions, and the outer sides of the plurality of protruding hook portions can contact the shielding shell 1, so that the plug electrical connector 100 can be positioned, conducted and grounded in the socket electrical connector.

[0081] The signal terminal set 4 is composed of sixteen terminals in two rows, and is suitable for transmitting USB 3.0 signals (high-speed signals). The arrangement position corresponds to the structural design of the first contact section 31 and the second contact section 32 in the upper and lower rows. Figure 7 As shown in FIG. 1 , the upper row from right to left includes the first pair of first flexible high-speed signal terminals 41 (TX1+-, differential signal terminals), the first function detection terminal (CC1, used to detect the function of forward and reverse insertion and the function of identifying the CABLE), a pair of first flexible low-speed signal terminals 42 (D+-, differential signal terminals), the first reserved terminal (RFU), and the second pair of first flexible high-speed signal terminals 41 (RX2+-, differential signal terminals). The lower row from left to right includes the first pair of second flexible high-speed signal terminals 41 (TX2+-, differential signal terminals), the second function detection terminal (CC2, used to detect the function of forward and reverse insertion and the function of identifying the CABLE), a pair of second flexible low-speed signal terminals 42 (D+-, differential signal terminals), the second reserved terminal (RFU), and the second pair of second flexible high-speed signal terminals 41 (RX1+-, differential signal terminals).

[0082] In some embodiments, the signal terminal set 4 is further configured to form eight terminals in a single row and is compatible with transmitting USB 3.0 signals (high-speed signals). The signal terminal set 4 is a plurality of terminals that can form a single arrangement, and there is no structural design of two rows of first contact segments 31 and second contact segments 32. From the front view of each terminal of the signal terminal set 4 (such as Figure 7As shown in the upper row of terminals, from right to left, they are a first pair of flexible high-speed signal terminals 41 (TX2+-, differential signal terminals), a reserved terminal (Secondary Bus, referred to as SBU2), a pair of flexible low-speed signal terminals 42 (D+-, differential signal terminals), a detection terminal (VCON) and a second pair of flexible high-speed signal terminals 41 (TX2+-, differential signal terminals).

[0083] The signal terminal set 4 is composed of eight flexible terminals and is suitable for transmitting USB 3.0 signals, but is not limited thereto. In some embodiments, the first pair of flexible high-speed signal terminals 41 (TX2+-, differential signal terminals), the second pair of flexible high-speed signal terminals 41 (TX2+-, differential signal terminals), and the reserved terminals (Secondary Bus, SBU2 for short) can be omitted, and only at least some of the flexible terminals are reserved for transmitting USB 2.0 signals, thereby reducing the number of terminals.

[0084] The power terminal group 3 and the signal terminal group 4 are arranged side by side to define the terminal arrangement position and pin position of the USB Type-C plug electrical connector. Each first contact segment 31 and each second contact segment 32 are point symmetrical with each other with the center point of the storage slot as the symmetry center. The so-called point symmetry means that after rotating each first contact segment 31 and each second contact segment 32 180 degrees based on the symmetry center as the rotation center, the rotated first contact segments 31 and each second contact segment 32 completely overlap, that is, each rotated first contact segment 31 is located at the original arrangement position of each second contact segment 32, and each rotated second contact segment 32 is located at the original arrangement position of each first contact segment 31. In other words, each first contact segment 31 and each second contact segment 32 are upside down, and the arrangement of each first contact segment 31 is opposite to the arrangement of each second contact segment 32.

[0085] Reference Figure 12 to Figure 13 , Fig.12 For decomposition diagram, Fig.13 2 is a top view of a cross-sectional view of a second embodiment of a plug electrical connector. In this embodiment, the plurality of hooks 5 are bent hooks 5 , which are disposed on both sides of the insulating body 2 and extend into the slot 21 .

[0086] In summary, according to some embodiments, the power terminal set and the signal terminal set are designed with different cross-sectional areas to form different types of terminals. The power terminal set and the signal terminal set are arranged in the same plug electrical connector, so that the plug electrical connector can transmit a current of more than 6A and meet the Gen 2 specification.

[0087] The terminals of the signal terminal group are generally of uniform thickness in all parts, which is convenient for high-speed signal transmission and adjustment of high-frequency characteristics. The terminals of the power terminal group are generally of non-uniform thickness in all parts, forming a tapered shape (for example, but not limited to, the second pin is wider, and the thickness gradually becomes thinner towards the second contact section). The signal terminal group uses bent terminals to meet the Gen2 specification and is used on terminals used for signal transmission. The power terminal group uses blanking terminals and is used on terminals used for power transmission. The cross-sectional area of ​​the blanking terminals is larger than that of the bent terminals and can meet the current transmission of more than 7A. The blanking terminals are faster when used for charging than the bent terminals.
