New description: [New technical field] This creation is not related to the electromagnetic shielding design of electrical connectors, especially the shielding structure on the stacked electrical connectors. [Prior Art] Based on the saving of electricity, the configuration of the device, for example, the heap 4 crying, for example, the integration of the C〇M connector and the VGA connector of the stack of electrical connectors. There have been several proposals for reading stacked electrical connections. For example, the stacked electrical connector shown in the sixth figure has a metal cover 9 〇 on the lower connection, and the metal cover has three pins. The three-pin 91 and the upper connector 92. The pin 93 and the pin 95 of the lower connector 9 are integrated into a bottom plate %. The metal cover can be connected to the ground of a computer motherboard through the pin 91 to provide shielding. However, since the general-purpose computer motherboard does not provide a line for soldering the pins 91, it is necessary to additionally manufacture a special electric age enemy having a line for soldering the pins 91, in order to be able to stack the above-mentioned electric Connector. The superimposed connector disclosed in the Japanese Patent Publication No. 1295867 generally provides two types of shielding structures. The first type of shielding structure is such that the shield 408 on which the first connector is attached is connected to the metal casing 4〇6. The second type of shielding structure is such that the shield 508 on the first 3 M353548 connector 502 is connected to the metal truss. The seventh type of structure refers to the vehicle, wherein the signal S indicates the signal on the pin 514 in the first connector 5〇2 and its flow direction. Since no loop is formed (as indicated by A), the (10) shield cannot sense the reverse current from the signal S, so that the electromagnetic shielding effect provided by the second shield structure is actually limited. As for the first type of shielding structure, the same problem exists. [New Content] The main purpose of the present invention is to provide a stacked electrical connector having a shield structure comprising a first connector, a second connector, and two metal bracket shells. The first connector includes an insulator and a metal case, and the insulating member 3 has a holding portion and a connecting portion. The connection portion is at one end of the first connector. The metal case covers the connection portion. The second connector is located above the first connector. The two metal brackets are respectively located on two sides of the first and second connectors, and each of the metal brackets has a vertical plate and a horizontal plate. The vertical board is connected to the first and second joints. The horizontal board is extended from the social board alone, and the financial and lion office is fixed on the vertical board. The clamshell covers the holding of the insulator of the first connector and the front side of the shielding case is electrically connected to the metal shell of the first connector and the two metal branches. The rear sides of the two sides of the shield case are electrically connected to the pins on the sill of the age bracket. In addition to the previous Chi, this Qing's face shell has to be connected to the computer board on the computer board, and there is no need for an additional 4 M353548. The line is used to solder the feet, this silk-electric age board You can bribe the power generation connection of the built-in. More importantly, the front side of the extracted leg shell is electrically connected with the metal shell and the metal bracket, and the side_back side and the joint of the two metal brackets are connected. The shield casing of the present invention can be signaled from the pin. Inductive reverse current' is used to provide good fortune (4). ^ i in the side of the pick more detailed skills _ _, _ after the description. • [Embodiment] The stacked electrical connectors shown in the first to third figures include a first connector - a second connector 2, two metal brackets 3, a shield case 4, and a wire $. In the basin: the first connector 1 includes an insulator 1 , a plurality of pins ^ and a metal shell 12. The insulator 1 includes a holding portion 13, a connecting portion 14 and a shoulder portion 15'. The connecting portion 14 is located at the end of the first connector, and the shoulder portion 15 is located at the holding portion and the connecting portion. Between 14. The plurality of pins ih are connected to a computer motherboard by the holding portion 13 of the insulator 1 through the connecting portion. The metal shell 12 is coated on the connecting portion 14. The second connector 2 is positioned above the first connector 丨. The two metal brackets 3 are respectively located on both sides of the first connector and the second connector 2. Each of the metal brackets 3 has a vertical plate % and a horizontal plate μ, and the vertical plate 3 and the horizontal plate 31 are connected to form an L shape. The vertical plate 3 (H is fixed to the connector 1 and the second connector 2. The horizontal plate 3i extends from the lower end of the M353548 of the vertical plate buckle and has a pin 32 for welding to the main brain motherboard The shield double 4 is covered by the insulator (7) of the first connector i. The front side of the shield has an extension piece 4〇 extending to the side of the shoulder and being broken by the metal. Between the shell 12 and the shoulder portion 15, the metal shell 12 is electrically connected to the extension piece (10). The front side of the face of the shield case 4 is respectively contacted with one side of the handle metal bracket 3 to form an electrical connection. The rear sides of the two sides of the shield case 4 are soldered to the pins 32 of the cross plates w of the two metal brackets 3 such that the rear sides of the two sides of the shield case 4 are electrically connected to the pins 32. The back side of the two sides of the shielding shell 4 and the horizontal plate 31 of the ten metal bracket 3 can also be electrically connected with the briquetting structure. The two screws 5 are screwed to the first connector 1 The metal shell i2, the shoulder portion 15 and the vertical plates 3 of the two metal brackets 3 electrically connect the metal shell I2 with the vertical plate 30. The fourth figure shows the original A simple schematic diagram of the shielding structure, wherein the signal S indicates the signal on the first connector 1_talking 11 and its flow direction; the shielding shell 4 forms a loop lazy. The shielding shell 4 will reverse the current from the signal s. The system can provide better electromagnetic shielding effect. The eighth picture shows the far-field test results of the connector of the 1295867 Taiwan invention patent case. Lai Zhong can see that the connection will cause many connectors to be light σ. The energy frequency to the first connector exceeds the limit value (points 1 to 10 as shown). The fifth figure shows the far-field light-expo test results of the connector of the present creation, and the first connection can be seen from the figure. The energy frequency of the combination of the two connectors is 6 M353548. Under the _ experimental data, it is clear that the mine has the effect of reducing the electromagnetic wave intensity. "Because of this I] The screen enemy 334 series * 胄 have an extra pin to connect to the computer motherboard, shame her (four) age, she does not need _ outside the line to solder those pins 'so can be suitable - general _ motherboard Especially before the shield case 4 of this creation The side is electrically connected to the metal (4) of the first connector! and the vertical plate 3G of the two metal=frame 3, and the rear side of the side is electrically connected with the pin on the horizontal plate 3! of the two metal trusses 3 Therefore, the shield double 4 of this creation induces a reverse current from the signal on the pin 32, so that it can provide a better electromagnetic shielding effect. ...,, how can 'anyone can from the description of the above example Get enough teaching, and understand that this creation does have industrial applicability and progress. = This creation has not seen the same or similar technology in the same field, and it has been exposed in the first place. It has indeed met the requirements of the new patent, and has applied for it according to law.
