[0096] The secondary terminal group 15 has a secondary terminal group projection surface S2 (e.g., Figures 19 to 20 (As shown), and the secondary terminal group 15 has at least one primary-side first conductive terminal 151 and at least one primary-side second conductive terminal 152 for transmitting conductive signals or ground signals. Figure 4 As shown, the secondary first conductive terminal 151 is, for example, a metallic conductor, and has a secondary first conductive terminal mating structure 1511 and a secondary first conductive terminal welding structure 1512. Additionally, as...

[0097] In this invention Figures 13 to 18 In the embodiment shown, the inner insulating terminal block 12 has a main side first positioning structure 121, a main side second positioning structure 122, a secondary side first positioning structure 123, and a secondary side second positioning structure 124.

[0098] In this embodiment, the first positioning structure 121 on the main side of the inner insulating terminal block is, for example, a slot structure, used to position (e.g., through positioning) the first conductive terminal 111 on the main side, so that the first conductive terminal 111 on the main side is in a predetermined position and extends in a direction parallel to the projection plane S1 of the main side terminal group (e.g., Figure 19 As shown, the first conductive terminal docking structure 1111 on the main side can be used to dock the docking part 21 of the docking member 2 for transmitting conductive signals or grounding signals, and the first conductive terminal welding structure 1112 on the main side can be used to weld the welding part 31 of the welding member 3 for transmitting conductive signals or grounding signals.

[0099] Additionally, the secondary side first positioning structure 123 of the inner insulating terminal block is, for example, a slot structure, used for positioning (e.g., through-positioning) the secondary side first conductive terminal 151, so that the secondary side first conductive terminal 151 is in a predetermined position and extends in a direction parallel to the projection plane S2 of the secondary side terminal group (e.g., Figure 19 As shown, the secondary first conductive terminal mating structure 1511 can be used to connect the mating part 21 of the mating member 2 for transmitting conductive signals or grounding signals, and the secondary first conductive terminal welding structure 1512 can be used to weld the welding part 31 of the welding member 3 for transmitting conductive signals or grounding signals.

[0100] In this embodiment, the second positioning structure 122 on the main side of the inner insulating terminal block is, for example, a slot structure, used to position (e.g., through positioning) the second conductive terminal 112 on the main side, so that the second conductive terminal 112 on the main side is in a predetermined position and extends in a direction parallel to the projection plane S1 of the main side terminal group (e.g., Figure 19 As shown, the main side second conductive terminal docking structure 1121 can be used to dock the docking part 21 of the docking member 2 for transmitting conductive signals or grounding signals, and the main side second conductive terminal welding structure 1122 can be used to weld the welding part 31 of the welding member 3 for transmitting conductive signals or grounding signals.

[0101] Additionally, the secondary side second positioning structure 124 of the inner insulating terminal block is, for example, a slot structure, used for positioning (e.g., through-positioning) the secondary side second conductive terminal 152, so that the secondary side second conductive terminal 152 is in a predetermined position and extends in a direction parallel to the projection plane S2 of the secondary side terminal group (e.g., Figure 19 As shown, the secondary conductive terminal mating structure 1521 can be used to connect the mating portion 21 of the mating member 2 for transmitting conductive signals or grounding signals, and the secondary conductive terminal welding structure 1522 can be used to weld the welding portion 31 of the welding member 3 for transmitting conductive signals or grounding signals.

[0102] It should be noted that, in the present invention Figure 5 In the illustrated embodiment, the main-side terminal group 11 has a plurality of main-side first conductive terminals 111, and a main-side second conductive terminal 112 is adjacent to at least one of the plurality of main-side first conductive terminals 111. The main-side second conductive terminal 112 is used to shield the adjacent main-side first conductive terminals 111 to reduce the degree of external interference to the signal transmission of the adjacent main-side first conductive terminals 111, thereby meeting the signal transmission requirements of the electrical connector.

[0103] More specifically, in embodiments of the present invention, the projection area of ​​the main-side first conductive terminal 111 on the projection surface S1 of the main-side terminal group is the projection area A11 of the main-side first conductive terminal, and the projection area of ​​the main-side second conductive terminal 112 on the projection surface S1 of the main-side terminal group is the projection area A12 of the main-side second conductive terminal. The area of ​​the projection area A12 of the main-side second conductive terminal is larger than the area of ​​the projection area A11 of the main-side first conductive terminal, so that the main-side second conductive terminal 112 can shield the main-side first conductive terminal 111, thereby reducing the degree of external interference to the signal transmission of the main-side first conductive terminal 111 and meeting the signal transmission requirements of the electrical connector. Preferably, the projection area A11 of the main-side first conductive terminal is located within the projection area A12 of the main-side second conductive terminal, so that the degree of external interference to the signal transmission of the main-side first conductive terminal 111 is significantly reduced, thereby meeting the signal transmission requirements of the electrical connector.

[0104] Furthermore, in this invention Figure 5 In the illustrated embodiment, the secondary terminal group 15 has a plurality of secondary first conductive terminals 151, and a secondary second conductive terminal 152 is adjacent to at least one of the plurality of secondary first conductive terminals 151. The secondary second conductive terminal 152 can transmit a ground signal and can shield the adjacent primary first conductive terminal 11 to reduce the degree of external interference (such as EMI electromagnetic interference or noise interference) on the signal transmission of the adjacent secondary first conductive terminal 151, thereby meeting the signal transmission requirements of the electrical connector.

[0105] More specifically, the projection area of ​​the secondary first conductive terminal 151 on the projection surface S2 of the secondary terminal group is the projection area A21 of the secondary first conductive terminal, and the projection area of ​​the secondary second conductive terminal 152 on the projection surface S2 of the secondary terminal group is the projection area A22 of the secondary second conductive terminal. The area of ​​the projection area A22 of the secondary second conductive terminal is larger than the area of ​​the projection area A21 of the secondary first conductive terminal, so that the secondary second conductive terminal 152 can shield the secondary first conductive terminal 151, thereby reducing the degree of external interference to the signal transmission of the secondary first conductive terminal 151 and meeting the signal transmission requirements of the electrical connector. Preferably, the projection area A21 of the secondary first conductive terminal is located within the projection area A22 of the secondary second conductive terminal, so as to significantly reduce the degree of external interference to the signal transmission of the secondary first conductive terminal 151 and meet the signal transmission requirements of the electrical connector.

The external insulating terminal block main side second positioning structure 133 is, for example, a slot structure, used to position (e.g., through-positioning) the main side second conductive terminal 112, so that the main side second conductive terminal 112 is in a predetermined position. The external insulating terminal block secondary side second positioning structure 134 is, for example, a slot structure, used to position (e.g., through-positioning) the secondary side second conductive terminal 152, so that the secondary side second conductive terminal 152 is in a predetermined position.

[0107] In this invention Figure 7 In the illustrated embodiment, the main-side second conductive terminal 112 has an inner embedding structure 1123 and an outer embedding structure 1124. The outer embedding structure 1124 is used to embed the outer insulating terminal base 13, and the inner embedding structure 1123 is used to embed the inner insulating terminal base 12. Therefore, the main-side second conductive terminal 112 can respectively position the outer insulating terminal base 13 and the inner insulating terminal base 12, so that the main-side first conductive terminal mating structure 1111 and the main-side second conductive terminal mating structure 1121 are respectively located at the head end structure 131 of the outer insulating terminal base for mating the mating portion 21 of the mating member 2, and the main-side first conductive terminal welding structure 1112 and the main-side second conductive terminal welding structure 1122 are respectively located at the tail end structure 132 of the outer insulating terminal base for welding the welding portion 31 of the welding member 3.

[0108] Additionally, the secondary conductive terminal 152 has an inner embedded structure 1523 and an outer embedded structure 1524. The outer embedded structure 1524 is used to embed the outer insulating terminal base 13, and the inner embedded structure 1523 is used to embed the inner insulating terminal base 12. Therefore, the secondary conductive terminal 152 can respectively position the outer insulating terminal base 13 and the inner insulating terminal base 12, so that the secondary first conductive terminal mating structure 1511 and the secondary second conductive terminal mating structure 1521 are respectively located at the head end structure 131 of the outer insulating terminal base for mating the mating portion 21 of the mating member 2, and the secondary first conductive terminal welding structure 1512 and the secondary second conductive terminal welding structure 1522 are respectively located at the tail end structure 132 of the outer insulating terminal base for welding the welding portion 31 of the welding member 3.

The main-side bridging conductor 141 is, for example, a plastic conductor or a metal conductor, and has a main-side bridging conductor insertion structure 1411. The main-side bridging conductor insertion structure 1411 is used to insert into the inner insulating terminal base 12, so that the main-side bridging conductor 141 is embedded in the inner insulating terminal base 12.

Therefore, the present invention can achieve electrical connection between the conductive terminals on the upper part of the electrical connector without the need for additional jumpers, allowing electronic devices equipped with the electrical connector of the present invention to continue to develop in the direction of being thinner and smaller.

[0112] In the embodiment, the main side bridging conductor 141 and the secondary side bridging conductor 142 are formed as one piece, and the main side second conductive terminal 112 and the secondary side second conductive terminal 152 are formed as one piece, so that the main side second conductive circuit is electrically connected to the secondary side second conductive circuit.

[0115] Next, as Figures 15 to 16 As shown, the first connector semi-finished product is embedded in the outer insulating terminal block 13 so that the first connector semi-finished product and the outer insulating terminal block 13 constitute the second connector semi-finished product.

[0116] Then, as Figures 16 to 17 As shown, each main-side second conductive terminal 112 abuts against the main-side bridging conductor 141, and the main-side bridging conductor 141 bridging each main-side second conductive terminal 112, so that each main-side second conductive terminal 112 is electrically connected to form a main-side second conductive circuit.

[0117] It should be noted that the aforementioned embodiments of the electrical connector of the present invention may omit some components. For example, the primary side bridging conductor, the secondary side bridging conductor, and the secondary side terminal group may be omitted. That is, in the embodiments of the present invention, the electrical connector may optionally include only the outer insulating terminal block, the primary side terminal group, and the inner insulating terminal block.

[0118] The external insulating terminal block has an external insulating terminal block head end structure and an external insulating terminal block tail end structure.

[0122] The external embedding structure of the main side second conductive terminal is used to embed the external insulating terminal base, and the internal embedding structure of the main side second conductive terminal is used to embed the internal insulating terminal base, so as to respectively position the external insulating terminal base and the internal insulating terminal base, and the main side first conductive terminal docking structure and the main side second conductive terminal docking structure are respectively located at the head end of the external insulating terminal base structure, so as to dock the docking part of the docking component, and the main side first conductive terminal welding structure and the main side second conductive terminal welding structure are respectively located at the tail end of the external insulating terminal base structure, so as to weld the welding part of the welding component.

[0123] Wherein, the projection area of ​​the first conductive terminal on the projection surface of the main side terminal group is the projection area of ​​the first conductive terminal on the main side, and the projection area of ​​the second conductive terminal on the projection surface of the main side terminal group is the projection area of ​​the second conductive terminal on the main side. The area of ​​the projection area of ​​the second conductive terminal on the main side is larger than the area of ​​the projection area of ​​the first conductive terminal on the main side, so that the second conductive terminal on the main side can shield the first conductive terminal on the main side, thereby reducing the degree of external interference to the signal transmission of the first conductive terminal on the main side.

[0124] In summary, the electrical connector provided by this invention can achieve shielding through conductive terminals, thereby reducing the degree of external interference affecting the signal transmission of the electrical connector and meeting the signal transmission requirements of the electrical connector. Furthermore, the electrical connector proposed in this invention can achieve electrical connection between the conductive terminals on the connector through a bridging conductor. Therefore, this invention can achieve electrical connection between the conductive terminals on the connector without the need for additional bridging devices, allowing electronic devices equipped with this invention to continue to develop towards a thinner and smaller design.
