Description

The improvement adapter connector of memory card

Technical field

The utility model relates to a kind of improvement adapter connector of memory card, refers to that especially the switch on a kind of adapter of IC memory card has the improvement adapter connector of a sound sheet.

Background of invention

Press, along with the electronical record development of technology, such as key card that credit card, burglary-resisting system or the electronic lock that the fiscard that withdraw deposit to use, shopping are used uses or the like, or even the personal identification record etc. that proves, seeks medical advice also can use the mode of swiping the card to note down in the future.

Yet, present employed fiscard, credit card are made by each family is indivedual, if open a bank account in every family simultaneously, then have many cards simultaneously, add the key card of house, company's discrepancy etc. again, thereby must carry many cards, and fiscard must remember password again, if each tame fiscard password differs, so remember multiple cipher, will remember password when therefore using, whether correct, so cause inconvenience and trouble in the use if differentiating employed card again.

Thereby, there is the memory wafer that will have memory function to be produced on the IC memory card, and all data must be deposited record on card, as personal identification prove, the seek medical advice account number, password, house of record, each tame bank or the password that company comes in and goes out etc., all can be recorded in same IC memory card, thereby must exempt the trouble and inconvenience of carrying many cards.

Yet, all data loggings all are recorded in a slight IC memory card in the mode of electronics, if will read data only has the proprietary card reader of businessman, bank or government bodies to be read data, the IC memory card owner then can't read the data that it writes down, so comparatively trouble inconvenience.

Thereby, develop and a kind of adapter with plug-in mounting IC memory card, make this adapter computer of must pegging graft, must make IC memory card holder be able to computer and read data; And known adapter, as shown in Figure 3, on a circuit board a, be equiped with a connector b, and installing one has the shell fragment connector c of a plurality of shell fragment terminal c1 on circuit board a, be provided with a switch d in shell fragment connector c side again, and this switch d is provided with a perforation d11 in a pedestal d1, is provided with a upper terminal d12 and lower terminal d13 in this perforation d11, as shown in Figure 4.

Memory card e must be inserted adapter, make the memory wafer e1 of this memory card e be pressed against the shell fragment c1 of the shell fragment connector c on the circuit board a, and make memory card e must press the upper terminal d12 of switch d, this upper terminal d12 is got be pressed against downwards on the lower terminal d13, to start this adapter.

Yet after memory card e inserted adapter, this memory card there is no any sound or action after inserting adapter, and it is unknown whether this memory card accurately inserts adapter, and uncertain sense is arranged, so cause user's inconvenience in the use.

Summary of the invention

The purpose of this utility model is to provide a kind of improvement adapter connector of memory card, and the switch on a kind of IC memory card adapter has a sound sheet, must send sound in the time of the IC memory card must being inserted adapter, inserts to remind user's memory card.

The utility model is to provide a kind of improvement adapter connector of memory card, on a circuit board, be equiped with a connector, and installing one has the shell fragment connector of a plurality of shell fragment terminals on circuit board, be provided with a switch in shell fragment connector side again, and this switch is provided with a perforation in a pedestal, is provided with a lower terminal and upper terminal in this perforation; It is characterized in that: pedestal the place ahead of this switch is provided with a top pressing board that colludes shape, and this lower terminal is a sheet again, and is equiped with a sound sheet on lower terminal, and should ring sheet and contact conducting with lower terminal, and this upper terminal is pressed against and rings on the sheet again.

The utility model can remind user's memory card to insert, so the user is easy to use.

Embodiment

For making the utility model clear and definite more full and accurate, cooperate following each diagram to describe in detail as the back now:

At first, see also Fig. 1, the utility model is equiped with a connector 2 on a circuit board 1, and installing one has the shell fragment connector 3 of a plurality of shell fragment terminals 31 on circuit board 1, be provided with a switch 4 in shell fragment connector 3 sides again, and this switch 4 is provided with a perforation 411 in a pedestal 41, is provided with a lower terminal 42 and upper terminal 43 in this perforation 411, and this switch 4 must cause short circuit to prevent memory card 5 as start-up circuit when not reaching the location; Its feature is to be:

Pedestal 41 the place aheads of this switch 4 are provided with a top pressing board 412 that colludes shape, and this lower terminal 42 is a sheet again, and is equiped with a sound sheet 44 on lower terminal 42, and should ring sheet 44 and contact conducting with lower terminal 42.

According to above-mentioned structure, memory card 5 must be inserted adapter, make the memory wafer 51 of this memory card 5 be pressed against the shell fragment terminal 31 of the shell fragment connector 3 on the circuit board 1, and make memory card 5 must press the upper terminal 43 of switch 4, making this upper terminal 43 get to be pressed against downwards rings on the sheet 44, and because this sound sheet 44 contacts conducting with lower terminal 42, thereby started this adapter.

Moreover when upper terminal 43 is pressed against downwards when ringing sheet 44, this sound sheet 44 so can send sound because of being urged to lower recess, should ring again when sheet 44 downward bullets fall into and collide lower terminal 42, is produced sound equally; And when extracting memory card 5 out, this memory card 5 i.e. ejection upper terminal 43 no longer, makes upper terminal 43 not push and ring sheet 44 that this sounds sheet 44 gets final product resilience and sends sound, thereby is reached the effect of prompting.

Pedestal 41 the place aheads of this switch 4 are provided with a top pressing board 412 that colludes shape again, and when making this memory card 5 insert adapters, this memory card 5 must lean by this top pressing board 412, make this memory card 5 really pushing downwards ring sheet 44.

Comprehensive the above, the disclosed structure of the utility model does not in the past have, and can reach above-mentioned effect really, reason has possessed the important document of novel patent, files an application novel patent in accordance with the law, expects that an ancient unit of weight office gives examination and grants a patent, real is to feel praying.
