However, after the USB expansion card is inserted into the expansion slot 71 of the notebook computer 70, the base 511 and its USB connector 512 protrude beyond the slot of the expansion slot 71. It is still quite inconvenient to use. Therefore, an integrated USB expansion card has been proposed, as shown in Fig. 5, 3 Ό 4 Ό 5659, which is a new patent case of the announcement "No. M383837" "Extended interface with universal serial bus", which includes: The outer casing 60 is provided with a bracket 61; a circuit board 62 is fixed in the bracket 61 for receiving in the outer casing 60, and is provided with a host interface port 621 corresponding to the rear opening of the outer casing 60; and a USB connection The device 63 is disposed in the outer casing 60 and electrically connected to the circuit board 62, and corresponding to the front opening of the outer casing 60. The usb connector 63 includes a tongue 631, a plurality of USB terminals 63 and a half metal cover 633 » The USB connector 512 (shown in Figure 4) has a height greater than the height of the expansion card housing 60 and cannot be directly integrated into the expansion card body 5, and the new patent retains the metal housing of the USB connector. Half of them The semi-metal cover 633 is configured to reduce the height thereof, and then the bottom surface of the outer casing 6 is formed corresponding to the position of the circuit board 62 to form a recessed portion 6〇1, so that the opening height of the semi-metal cover 633 to the recessed portion 601 conforms to the standard USB plug height. Therefore, the USB connector 63 can be integrated into the casing 6〇), and the standard USB plug can be smoothly inserted. [New content] In view of the above technical disadvantages, the main purpose of the present invention is to provide an embedded USB expansion card that does not need to be changed. The original size of the expansion card matches the expansion slot of the notebook, so that the embedded type (JSR ik Λ* people's eight-type expansion card is inserted into the expansion slot of the notebook) is flush with the slot of the expansion slot, and DC power output is also provided. The main technical means used to achieve the above purpose is that the embedded USB expansion card includes a housing 4' which has a first front opening, a second front opening and a rear opening. a front opening height and width match the standard USB plug size; a power and signal conversion circuit board, the system is placed in the housing, and a rear interface is provided with a host interface port; a USB connector, disposed in the housing and facing the first front opening ′ and electrically connected to the power and signal conversion circuit board, comprising an insulating plate and a USB terminal protruding from the insulating plate and the insulating plate There are two gaps between the upper and lower end faces and the upper and lower plates of the casing; and a DC power socket is disposed in the casing and facing the second front opening 'and electrically connected to the power source and the signal conversion circuit board. The insulating board of the USB connector provided with the USB terminal is mainly placed in the outer casing to achieve the effect of being embedded in the expansion card, and the semi-metal cover without the need for additional signal shielding is provided, the overall thickness is thinner and the structure is simple; In addition, this creation also provides a DC power socket, which is also embedded in the expansion card. After the creation is inserted into the expansion slot of the notebook computer, the USB connector and the DC power socket are flush with the expansion slot of the notebook computer. Flat, like the USB connector preset on the side of the notebook, and can provide another set of DC power for the external USB electronic device. [First Embodiment] Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention includes: a housing 60 having a bracket 61 formed therein and having a first front opening 101 and a first The second front opening 102 and the rear opening 103; wherein the first front 5 M405659 opening 101 has a height and a width matching the standard USB plug size; wherein the bracket 11 includes a positioning frame 111, and the positioning frame 1n corresponds to the outer casing 1 The two sides of the first front opening 1〇1 are respectively formed with a stopper 113 and a receiving box 114; The front end of the box 114 is formed by the second front opening 1 〇 2; a power supply and signal conversion circuit board 20 is fixed on the positioning frame 111 of the bracket 以 to be received in the outer casing 10, and is connected to the rear opening. 1〇3 is provided with a host interface port 21; wherein the host interface port 21 is located between the missing portions 11 2 of the bracket 11; the USB connector 30 is placed in the casing 1 and facing the first Month J opening 101' and electrically connected to the power supply and signal conversion circuit board The device includes an insulating plate 31 and a USB terminal 32 protruding from the insulating plate. The upper and lower end faces of the insulating plate 31 and the upper and lower plates of the outer casing 1 respectively have two gaps. In this embodiment, the USB terminal is USB3. The terminal comprises a total of 9 metal terminal pins; and the DC power socket 40 0 ' is disposed in the receiving box 114 of the housing bracket 11 and faces the second front opening 〇 2, and the power and signal conversion circuit The board 2 is electrically connected; since the external electronic device using the USB 3.0 plug requires a large power supply current, the creation expansion card is embedded in the DC power socket, and a set of DC power sources other than the DC power supply of the USB3.0 connector is provided. In addition, in order to increase the insertion strength of the external USB plug corresponding to the first front opening 1〇1 of the USB connector 30, the outer casing 10 is inwardly stamped correspondingly to the upper and lower plates of the upper and lower end faces of the USB insulating plate 31 to form at least 6 M405659 In this embodiment, a resilient clip 104' is stamped and formed with two parallel elastic clips 104, respectively. Please refer to FIG. 3, in use, the host interface port 21 is oriented in the expansion slot of the notebook computer to be inserted into the expansion slot 71. Since the housing 1〇 of the present invention matches the expansion slot 71, and the USB connection The 3 〇 and DC power sockets 40 are placed in the first and second front openings 1 〇 1, 102 ′ of the casing 10, so that they can be flush with the expansion slot 71 of the pen § computer for the USB plug and the DC power cord. Use it. In summary, the original design of the USB connector is provided with a USB terminal insulation board placed in the housing to achieve the effect of embedding into the expansion card, and the semi-metal cover without additional signal shielding is required, and the thickness is thinner. And simple structure. In addition, this creation also provides a DC power socket, which is also embedded in the expansion card. After the creation is inserted into the expansion slot of the notebook computer, the USB connector and the DC power socket are flush with the expansion slot of the notebook computer. The USB connector presets on the side of the notebook and provides another set of DC power for the external USB electronics.
