Technical field
The utility model relates to electrical category, particularly a kind of minisize memory card improvement of connector structure.
Background technology
As everyone knows, in recent years, because the progress of science and technology, people develop numerical digit electronic product miscellaneous and live with facility, digital still camera for example, the numerical digit video camera, the numerical digit walkman, PDA, mobile phone and notebook computer etc., and when using this type of numerical digit electronic product, just must use storage device to store numerical digit archives photograph, music, data such as film or software, wherein small memory card is in conjunction with the fast flash memory bank (FlashMemory) of semiconductor (Solid-state electronic) processing procedure, because volume is less, and easy to carry, replaced the multimedia document storage device that relatively large CD-RW discsCD-RW and disk become a new generation;
Small memory card provides rewritable, need not the storage device that power supply is preserved data, and external form lightly reaches preferable shockproof, the antimagnetic and dustproof environmental adaptation characteristic of tool; After asking the city from nineteen ninety flash memory (Flash Memory Card), have successively such as CF card (Compact Flash Card), SM card (Smart Media Card), mmc card (MultiMedia Card), MS card (Memory Stick Card), SD card (Secure Digital Card), xD card (xD-Picture Card) and T-Flash card small memory cards such as (Trans Flash) and release successively;
Yet, because the circulation that memory card miscellaneous is only given information to the numerical digit electronic product of supporting, so numerical digit electronic product such as numerical digit camera, numerical digit video camera, numerical digit walkman, PDA, mobile phone and notebook computer etc. must be by memory card card reading connector miscellaneous to read needed data, and for memory card connector can be plugged to read data for memory card miscellaneous, memory card connector all is set to the kenel of slot usually and combines with the circuit board of numerical digit electronic product, is convenient to the user and carries out reading and storing of data;
Still there is following point in above-mentioned memory card connector in use:
Memory card connector is in order to electrically connect the contact jaw of memory card, the capital is provided with one group of terminal group that is compatible to memory card according to the thickness length of memory card, and each terminal group is separately positioned on diverse location in memory card connector, yet, when memory card connector is gone in the memory card intercalation, memory card tends to touching to remaining terminal group in the memory card connector space, especially be adjacent to the terminal group of opening part, it causes all the other terminal group memory card that rubs easily, and then the problem of formation wearing and tearing memory card, and cause the problem of terminal wearing and tearing and elastic fatigue simultaneously easily, need be improved.
The utility model content
The purpose of this utility model is to provide a kind of minisize memory card improvement of connector structure, solved connector commonly used when memory card connector is gone in the memory card intercalation, memory card can touch remaining terminal group in the memory card connector space, easily cause the problem of all the other terminal wearing and tearing memory cards, and easily cause problems such as terminal wearing and tearing and elastic fatigue.
The technical solution of the utility model is: include pedestal, be provided with accommodation space in this pedestal, this pedestal one end is provided with the socket that communicates with accommodation space, is installed with the first terminal group, second terminal group and the 3rd terminal group on base bottom surface respectively; Slide block, this slide block is arranged in the accommodation space, and this slide block has the plural groove that can crisscross second terminal group, has rib on each groove simultaneously, the platform dual-side is extended with first contact part and second contact part respectively, being connected mutually between first contact part and pedestal has first flexible member, and there is second flexible member mutual the linking between second contact part and pedestal.
Above-mentioned the first terminal group is provided with for being compatible to xD memory card bank row;
Second terminal group is provided with for being compatible to SD memory card and MMC memory card bank row;
The 3rd terminal group is provided with for being compatible to MS memory card bank row;
Second terminal group includes plural contact site simultaneously, and each contact site is coated on each rib;
First flexible member and second flexible member are spring or elastic board chip;
The level height of slide block is higher than the first terminal group and second terminal group.
Advantage of the present utility model is: can avoid memory card to touch all the other interior terminal group of connector, reduce the wearing and tearing and generation elastic fatigue of memory card and terminal group; Can prevent that terminal group is rubbed by memory card, can carry out the purpose of memory card contact simultaneously to second terminal group, practical.

Embodiment:
To shown in the accompanying drawing 3, the utility model memory card connector 1 comprises as accompanying drawing 1:
Pedestal 2, these pedestal 2 upper covers have lid 21, and be provided with accommodation space 22 within it, these pedestal 2 one ends are provided with the socket 23 that communicates with accommodation space 22, this socket 23 enters pedestal 2 inner wall at end and is respectively equipped with the first terminal group 24, second terminal group 25 and the 3rd terminal group 26 that is fixedly arranged on pedestal 2 bottom surfaces, and this first terminal group 24 is provided with for being compatible to xD memory card bank row; Second terminal group 25 is provided with for being compatible to SD memory card and MMC memory card bank row; The 3rd terminal group 26 is provided with for being compatible to MS memory card bank row;
Slide block 3, this slide block 3 is arranged in the accommodation space 22, and these slide block 3 one sides have the plural groove 31 that can crisscross second terminal group 25, has rib 32 respectively in each groove 31, each rib 32 is accommodated in the plural contact site 251 times of second terminal group 25, and the level height of slide block 3 is higher than the plural contact site 251 of the first terminal group 24 and second terminal group 25, slide block 3 both sides are extended with first contact part 33 and second contact part 34 respectively, first contact part 33 is connected mutually with 2 of pedestals first flexible member 4,2 of second contact part 34 and pedestals are connected mutually that second flexible member, 5, the first flexible members 4 and second flexible member 5 are arranged is spring or elastic board chip.
