Description

Thinned NGFF card edge connector

The present invention relates to a connector, in particular to a thinned NGFF card edge connector that can be lowered in height without breaking or sinking.

The technology of data access devices has evolved from hard disk drives to smaller, faster Solid State Drives (SSDs). More and more devices are beginning to be equipped with solid state drives. Connect the SSD card (short for the solid state drive expansion card), these devices need to set the card edge connector.

The existing standard for solid state drives is the mSATA standard, but its limitations are too limited, resulting in limited capacity. Therefore, the new standard for solid state drives, the NGFF (Next Generation Form Factor) standard, is smaller than the mSATA standard. The capacity is higher, and it also has the advantage of reducing the cost.

Due to the different specifications of the SSD cards produced by each manufacturer, and the fixed connection of the NGFF card edge connectors, the overall height after the plugging is also different. For example, the conventional NGFF card edge connection The SSD card can only be inserted, and the SSD card inserted will make the flash memory chip face up. Therefore, some memory chips will be made due to different manufacturing methods of different brands of memory chips or different manufacturers. The height is too high to be installed, resulting in a maximum height limit: 2.45mm, which represents the board from the board The maximum height between the top edge of the NGFF card edge connector for thin and light computers, even ultra-thin notebooks (Ultrabook). With this limitation, some NGFF card edge connectors with an overall height exceeding 2.45 mm due to the high memory chip height must be machined to open an opening on the board to sink the NGFF card edge connector into the opening. Internally, the height is lowered, but the area of the board for plugging in electronic parts is reduced.

Secondly, the upper row of lead terminals and the lower row of lead terminals are moved down together, but the distance between the end of the guiding section and the bottom surface of the NGFF card edge connector is known after the lower row of the leading terminal is moved downward. It will be reduced accordingly, which will result in insufficient elastic margin when plugging the SSD card, which will affect the plug stability of the SSD card.

The three are to change the lower row of lead terminals to have no elasticity, such as plated type lead terminals. Since these plated type lead terminals are not flexible, the SSD card will be warped or bent after the SSD card is inserted. In this case, it is impossible to make electrical contact with all the lower row of lead terminals.

One of the purposes of this creation is to provide a thinned NGFF card edge connector, which can reduce the overall height without sinking or breaking the board by being able to reversely insert the card edge connector of the SSD card, thereby eliminating the need to The trouble of opening the opening does not reduce the area that the board is used to plug in electronic parts, and it can be applied to thin and light computers, even ultra-thin notebooks (Ultrabooks).

The second objective of the present invention is to provide a thinned NGFF card edge connector, which has a design of a lower conductive terminal and a separation distance so that the lower guiding portion has a foot. The elastic force and the separation distance are sufficient to ensure that the upper guiding portion and the lower guiding portion can electrically contact the lower contact portion and the upper contact portion of the SSD card, and there is no inaccessibility, thereby enabling the SSD card to It is inserted into the socket of the card edge connector to achieve the convenience of inserting the card first and then pressing down the positioning.

In order to achieve the above object, the present invention provides a thinned NGFF card edge connector for plugging an SSD card, the SSD card having a plurality of upper contacts and a plurality of lower contacts, the card edge connector comprising: The splicing body has a top plate, a bottom plate and a socket between the top plate and the bottom plate, the socket is for re-inserting the SSD card; a plurality of upper conductive terminals are arranged side by side on the top plate, each of which is electrically conductive The terminal is formed with an upper guiding portion and a soldering portion, each of the upper guiding portions corresponding to each of the lower contact portions of the SSD card; and a plurality of lower conductive terminals disposed side by side on the bottom plate, each of the lower portions The conductive terminal is formed with a lower guiding portion and a soldering portion, and each of the lower guiding portions corresponds to each of the upper contact portions of the SSD card.

Compared with the prior art, the present invention has the following effects: the overall height can be lowered without sinking or breaking the board, thereby eliminating the trouble of opening the opening and reducing the area for the board to be used for plugging electronic parts, and Can be applied to thin and light computers, even ultra-thin notebooks (Ultrabook).
