Description

A kind of detachable deck and portable terminal

Technical field

The utility model relates to a kind of card connection, relates in particular to a kind of detachable deck and portable terminal.

Background technology

SIM(Subscriber Identity Module) card, i.e. client identification module, it is also referred to as smart card, subscriber identification card, and the GSM digital mobile telephone must be loaded onto this card and can use.It has stored digital mobile phone client's information on a computer chip, encrypted secret key and user's contents such as telephone directory can be differentiated for GSM network client identity, and the voice messaging the when client conversed is encrypted.

Along with the Requirement Increases of consumer electronics, various electronic product develop rapidlys; Its functional requirement is also continuous mutually perfect, and present most of consumption electronic products all require compatible SIM card function, makes it satisfy conversation, online amusement multi-functional.As mobile phone, Pad etc.

The deck that is used to install SIM card in the prior art mainly adopts the SMT mode to be welded to circuit board by the leg on the deck.As Fig. 1 is circuit board and SIM card seat connected mode schematic diagram in the prior art, and SIM card seat 2 is welded on the circuit board 1 by leg 3.

The SIM card seat is crossed stove, and (crossing stove promptly melts Heraeus or soldering paste by curing oven or reflow soldering, make surface-assembled components and parts and circuit board strong bond together) after, the deck body is yielding, and (because of temperature in curing oven, the reflow soldering generally is to be raised to height the end of by, maximum temperature can reach 200 °, SIM card seat plastic cement part very easily is out of shape because of being subjected to high temperature), cause the deck pin to damage, the deck body is placed uneven, being uneven appearred in thickness when scolding tin melted, and the SIM card seat just increases in that paster back plane degree is bad; Possibility scolding tin deficiency in the SMT process causes rosin joint or sealing-off in addition, causes deck unreliable with being electrically connected of circuit board.So deck both had been not easy to deck by SMT and circuit board ways of connecting and had installed that to make that also it is connected unreliable.

Simultaneously, after the SIM card seat is installed on the circuit board, often have components and parts below the deck, if the components and parts corrupted below the deck, need earlier could further to keep in repair from the circuit board deck of dismantling, and the deck that is fixed on the circuit board by the SMT mode in the prior art just causes bad dismounting in the process of maintenance, and causes the SIM card seat body to damage in the unloading process easily, has also increased maintenance cost.

Be understandable that the statement of this part only provides the background information relevant with the utility model, may constitute or not constitute so-called prior art.
