Description

The Embedded USB expansion board

Technical field

The utility model is about a kind of USB expansion board, refers to a kind of Embedded USB expansion board especially.

Background technology

Notebook computer is because of volume restrictions, thus its default computer connector limited amount, and carry out communication in order to reserve with external electronic, so all be preset with an expansion slot; And also cooperate this standard expansion slot on the market and the expansion board of various difference in functionalitys or form is arranged.

With the USB expansion board, as shown in Figure 4, it includes a body 50, an and USB socket 51; This body 50 is provided with a signaling conversion circuit plate and a main frame interface link in a shell, USB socket 51 then is arranged at the front end of this body 50, and be electrically connected with the signaling conversion circuit plate of body, it includes a pedestal 511 and at least one USB connector 512, and each USB connector 512 includes a metal shell 513 and and is arranged at the electrical isolation tongue piece 514 in the metal shell 513 and is plugged in USB terminal (not shown) on this electrical isolation tongue piece 514.Just since standard USB connector 512 including a metal shell 513 and having the electrical isolation tongue piece 514 of USB terminal, so USB connector 512 must be arranged on this pedestal 511.But thus, after this USB expansion board inserted the expansion slot 71 of notebook computer 70, pedestal 511 and USB connector 512 thereof can protrude in outside expansion slot 71 notches, still quite inconvenience in the use.

Therefore existing people proposes a kind of integral type USB expansion board, as shown in Figure 5, for announcing " extending interface of tool universal serial bus " novel patent case M383837 number, includes:

One shell 60 is provided with a support 61 in it;

One circuit board 62 is fixed in the support 61 to be placed in this shell 60, and it is to being provided with a main frame interface link 621 in shell 60 after-opening places; And

One USB connector 63 is placed in this shell 60 and is electrically connected to this circuit board 62, and to should shell 60 open fronts, this USB connector 63 includes a tongue piece 631, plural USB terminal 63 and half metal cap 633.

Because standard USB connector 512 (as shown in Figure 4) height is greater than expansion board shell 60 room height, can't directly be integrated in this expansion board body 50, and this novel patent is that the metal shell of existing USB connector is kept wherein half, promptly adopt semimetal cover 633, to reduce its height, make shell 60 bottom surfaces to forming depressed part 601 downwards in circuit board 62 positions again, make the open height conformance with standard USB plug height of this semimetal cover 633, allow this USB connector 63 be integrated in the shell 60 and still can insert smoothly for the standard USB plug to depressed part 601.

Summary of the invention

Because above-mentioned technical disadvantages, the utility model fundamental purpose provides a kind of Embedded USB expansion board, must not change expansion board life size, coupling notebook computer expansion slot, after making the Embedded USB expansion board insert the notebook computer expansion slot, flush with the expansion slot notch, and provide the direct supply output function in addition.

Desiring to reach the employed major technique means of above-mentioned purpose is to make this Embedded USB expansion board include:

One shell, it is formed with one first open front, one second open front and an after-opening, and wherein this first open front height and width are match-on criterion USB plug sizes;

One power supply and signaling conversion circuit plate are placed in this shell, and to being provided with a main frame interface link by after-opening;

One USB connector, be placed in this shell and towards this first open front, and be electrically connected with this power supply and signaling conversion circuit plate, it includes an insulcrete and protrudes in USB terminal on the insulcrete, has two gaps respectively between this insulcrete upper and lower end face and the shell upper and lower plates again; And

One direct current supply socket is placed in this shell and towards this second open front, and is electrically connected with this power supply and signaling conversion circuit plate;

The upper and lower plates of the insulcrete upper and lower end face of the corresponding USB connector of this shell inwardly forms at least one elastic clip respectively;

Be provided with a support in this shell, it includes:

One posting is for power supply and the signaling conversion circuit plate in the fixed housing;

Two folder portions are that after-opening two opposite sides from the corresponding shell of this posting stretch out respectively, establish the main frame interface link of this power supply and signaling conversion circuit plate with folder;

One block is wherein extending before the side direction from first open front, two opposite sides of the corresponding shell of this posting; And

One container is that the opposite side from first open front, two opposite sides of the corresponding shell of this posting extends forward, and this container front end system forms it for this second open front again, and ccontaining this Direct current power source socket of this container is in wherein;

The USB terminal of this USB connector is to be the USB3.0 terminal.

The insulcrete that above-mentioned the utility model mainly makes this USB connector be provided with the USB terminal is placed in the shell, reaches to be embedded in effect in the expansion board, and the extra semimetal enclosing cover that covers of signalization, quite simple on the structure; In addition, the utility model also provides a direct current supply socket, is embedded in the expansion board equally; Make the utility model insert that this USB connector and this Direct current power source socket flush with notebook computer expansion slot notch behind the expansion slot of notebook computer, as the default USB connector of notebook computer side, and can provide the external USB electronic installation another group direct supply.
