Description

Card connector

Technical field

A kind of card connector is the utility model is related to, espespecially the push unit of card connector is provided with holding shrapnel, you can profit Be held in holding shrapnel in the groove of memory card side, make memory card positioning really, be not easy to release, and memory card exited Cheng Zhong, the contact arm of shield shell can be relied on to support to arrive in holding shrapnel upwards, holding shrapnel is departed from groove, reached smooth and insert Block, move back the effect of card.

Background technology

Press, electronic product, the one side function such as mobile phone now, digital camera, notebook computer, personal digital assistant are got over Come more powerful, the requirement to amount of data storage is also increasing, on the other hand, but both facing to light, thin, short, small development in volume, And memory card connector is usually to be installed directly on circuit board, for planting various memory card, enable in card data via this Memory card connector and with circuit board be electrically connected with.

Therefore, memory card and its connector are also relatively more made smaller, and the gap between its terminal is also very close to so to note Recall the fashionable reliable location of card insertion, lock, make correct, good contact is kept between memory card contact, and keep stable and connect Connect without voluntarily releasing, just seem critically important, and the connector product of prior art, do not paid attention to and solved.

Utility model content

Therefore how to try solving above-mentioned existing missing and inconvenience, the related dealer institute for being as engaged in the industry is urgently Where improved direction to be studied.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of card connector, it is characterized in that including pedestal, push unit and shield shell, wherein：

The pedestal has plug division, and the plural wears groove for plural terminals positioning is provided with plug division, and plug division two Side is extended with support arm backwards in the same direction, then has opening and the grafting entered for preset memory card insertion formed with rear between two support arms Space, and grafting space side and be located therein a support arm and be provided with slipping part；

The push unit is positioned in the slipping part of pedestal, and with the push block for slide displacement in slipping part, and Formed with the passage for preset memory card pushing tow on the inside of push block, and holding shrapnel is located in push block, the clasp bullet Piece one end is extended with the fixed part for being positioned in push block, and holding shrapnel is extended with confession backwards in contrast to one end of fixed part The clasp elastic arm being held in the groove of preset memory card side；

The shield shell is covered and is incorporated into outside pedestal, and the shield shell surface is provided with perforation, and the rear on the inside of perforation Wall is provided with to the oblique contact arm stretched and support to arrive in the clasp elastic arm of holding shrapnel upwards forward.

Wherein：The push block of the pedestal is cutd open provided with storage tank, and storage tank top surface centre adjacent to passage one side Locating piece is convexly equipped with down, and the fixed part side wall of the holding shrapnel extends outwardly for the plural number folder being inserted into storage tank Gripping arm, and formed with the grasping part for being held on locating piece surface between plural clamping limb.

Wherein：The clasp elastic arm end of the holding shrapnel is bent with for being held in the groove of preset memory card side Point is detained, and detains point rear surface formed with skewed supporting surface, and the contact arm forward surface of the shield shell is formed with confession Guide supporting surface and clasp elastic arm is produced the guiding incline shifted up, then on shield shell surface and in front of contact arm The arrived tableting in arcuation is arranged with one distance downwards.

Major advantage of the present utility model is in that：When memory is stuck in grafting space after secondary pressing, you can complete Plug-in card into one cycle start, card motion is moved back, and during plug-in card, memory card can be held in using holding shrapnel In a positioning in the groove of side, with the effect with pintle hook lock, so memory card is avoided to depart from easily, and then make electronic signal steady Fixed transmission, and during card is moved back, its clasp elastic arm can then be guided by contact arm, shift up clasp elastic arm and take off From the limitation of the groove of memory card side, and clasp elastic arm is supported to arrive on contact arm surface, inserting for pedestal is arrived without obstruction Space use is connect, and then can swimmingly be carried out for plug-in card operation again, so reaches smooth plug-in card, move back the purpose of card.
