Edge, half touching shell fragment, when being forced into so may puncture printed circuit board (PCB) top layer take out SD card pallet, in the course of time
Printed circuit board (PCB) surface line will be caused to be broken, cause mainboard to damage.
Utility model content
In order to overcome above-mentioned technological deficiency, the purpose of this utility model is to provide a kind of digital product and its printed circuit
Plate, the printed circuit board (PCB) can cause using probe touching shell fragment during, no longer touch the edge of printed circuit board (PCB),
Protect printed circuit board (PCB).
The utility model discloses a kind of printed circuit board (PCB) of digital product, including printed circuit board (PCB) mainboard, institute is arranged at
SD card pallet can be carried thereon on the SD card seat on mainboard, the deck by stating, and an elastic parts is connected to the SD card
On pallet, the elastic parts has shell fragment, and the elastic parts is arranged to touch the shell fragment, can make the elastic parts
The SD card pallet is ejected from the deck, it is characterised in that the board edges and the shell fragment are spaced apart.
Preferably, the board edges are inwardly recessed in the shell fragment position, formed recess, the board edges with it is described
Shell fragment is spaced apart.
Preferably, the shell fragment is outstanding from the board edges, and the board edges and the shell fragment interval are certain
Distance.
Preferably, the elastic parts includes connecting rod and the bottom bar being connected with the connecting rod, touches the shell fragment, then described
Shell fragment drives the bottom bar to release the SD card pallet by connecting rod.
The application also provides a kind of digital product, including casing and is arranged in the casing printed circuit as described above
Plate, wherein offering jack corresponding to the shell fragment position on the casing.
Preferably, the digital product is mobile phone.
Employ after above-mentioned technical proposal, compared with prior art, can be prevented to master when extracting SD card using probe
The destruction of plate.

Embodiment
Advantage of the present utility model is expanded on further below in conjunction with accompanying drawing and specific embodiment.
As shown in figure 1, the digital product of prior art includes casing 2 and the printed circuit board (PCB) being arranged in casing 2.Machine
There is jack 8 on shell 2, printed circuit board (PCB) includes printed circuit board (PCB) mainboard 3, be arranged at the SD card seat 5 on the mainboard 3, the card
SD card pallet 1 can be carried on seat 5 thereon, and elastic parts includes connecting rod and with connecting rod in one section of bottom bar being connected, shell fragment 6
The other end of connecting rod is arranged at, shell fragment 6 is touched, connecting rod can be pushed, so that connection-rod linkage bottom bar.Using the principle of lever, make
SD card pallet 1 is ejected from deck 5, so as to protrude from outside casing 2, but is due to shell fragment 6 and the edge of printed circuit board (PCB) main body 3
It is substantially flush or the edge of printed circuit board (PCB) mainboard 3 is protruded little by little than shell fragment 6, when touching shell fragment 6 using probe 4, easily
First touch the edge of printed circuit board (PCB) mainboard 3 or half touches the edge of printed circuit board (PCB) mainboard 3, half touches shell fragment 6,
When being forced into and then the top layer of printed circuit board (PCB) mainboard 3 may be punctured take out SD card pallet 1.
It is illustrated in figure 2 the schematic diagram of the utility model one embodiment.Digital product is mobile phone in the present embodiment,
It can be the digital product such as digital camera, SD card is Micro SD cards or Mini SD cards, including casing 2 and be arranged at casing 2
Interior printed circuit board (PCB).There is jack 8 on casing 2, printed circuit board (PCB) includes printed circuit board (PCB) mainboard 3, is arranged on the mainboard 3
SD card seat 5, SD card pallet can be carried on the deck 5) thereon, elastic parts includes connecting rod and with connecting rod in one section of phase
The bottom bar of connection, shell fragment 6 is arranged at the other end of connecting rod, touches shell fragment 6, connecting rod can be pushed, so that connection-rod linkage bottom bar.Make
With the principle of lever, SD card pallet 1 is set to be ejected from deck 5.The edge of printed circuit board (PCB) mainboard 3 it is corresponding with jack 8 place to
Interior formed has a certain distance between recess 7, therefore the edge of printed circuit board (PCB) mainboard 3 and the shell fragment 6, user uses spy
Pin 4 is first contacted by jack 8 with shell fragment 6, and then shell fragment 6 pushes connecting rod again, and connection-rod linkage bottom bar causes SD card pallet to eject, by
Have recess 7 in now corresponding printed circuit board (PCB) body rim, so probe will not touch printed circuit board (PCB) body rim, with up to
To preventing the damaged beneficial effect of circuit board main body.
It should be noted that embodiment of the present utility model has preferably implementation, and not the utility model is appointed
The limitation of what form, any one skilled in the art changes or is modified to possibly also with the technology contents of the disclosure above
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model
Any modification or equivalent variations and modification that above example is made, in the range of still falling within technical solutions of the utility model.
