When the memory card is inserted, the latching portion of the locking device is buckled. Enter the groove on the side of the memory card, and when you want to pull out the memory card, you only need to pull the trigger part of the lock device to easily pull out the memory card, so that the lock card can be easily and easily removed. .

According to the currently used flash memory card, referred to as the memory card, the use is more and more extensive, especially for single, independent or temporary data storage, which can eliminate the large-capacity setting of the memory card, and at the same time, through the single card The use of physical memory cards can bring great convenience to the storage and file management of specific data, especially consumer electronic products such as mobile phones, digital cameras, digital cameras, MP3 players or personal digital assistants (PDAs). The memory card used can be divided into CFexpress card, MMC card (Multi-Media Card), SD card (Secure Digital Card), SM card (Smart Media Card), MS card (Memory Stick Card), etc. They are based on a series of memory cards that have been improved and designed, such as the MICRO SD card.

Today's mobile phones, digital cameras, notebook computers, personal digital assistants and other electronic products, on the one hand, are becoming more powerful, and the demand for data storage is increasing. In terms of volume, the volume is light, thin, short, and small, and the memory card connector is generally directly mounted on the circuit board for inserting various types of memory cards, so that the data in the card can be connected via the memory card. And electrically connected to the circuit board.

Therefore, the memory card and its connector are also relatively smaller and smaller, and the gap between the terminals is also close, so that the memory card is reliably positioned, locked, and kept correctly with the memory card contacts. It is important to have good contact and maintain a stable connection without loosening it, and the prior art connector products have not been taken seriously.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction that the relevant industry players in this industry are eager to study and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, evaluated and considered them through multiple parties, and through years of experience in the industry, through continuous trial and modification, the card connectors were designed.

The main purpose of the present invention is that the socket portion of the body is provided with a plurality of slots for positioning the plurality of terminals, and the two sides of the plug portion extend in the same direction and extend back with an arm, and between the two arms. Forming a plug-in space with an opening at the rear, and one of the insertion spaces is recessed with a receiving groove, and a locking device is positioned in the receiving groove, and the base of the locking device is reversed at the back There is an actuating portion, and a deformation space for pressing deformation is formed between the actuating portion and the base portion, and a latching portion is further disposed on the surface of the actuating portion, and the surface of the actuating portion is extended with respect to the other side of the latching portion. a slidable portion for displacing the actuating portion toward the base portion, and a shield shell for covering the outer portion of the base body, the shield case having a base plate and being bent at opposite sides of the base plate Covering the side panels outside the two arms, and when the memory card is inserted into the docking space of the base body, the locking device thereof The buckle part is buckled into the groove on the side of the memory card to ensure a proper positioning, so as to avoid the memory card being easily loosened and pulled out, and only need to pull the lock card when the memory card is to be taken out from the docking space. The triggering portion of the device can disengage the memory card from the binding portion, so that the memory card can be easily pulled out from the docking space, thereby achieving the purpose of the card being securely and easily removed.

The secondary purpose of the present invention is that the central portion of the inner wall of the receiving groove of the seat body is provided with an inwardly protruding block, and the base of the locking device has a recess at the top of the base and is placed in a stop. The groove can be positioned to pass through the groove to have a good limit effect, thereby achieving stable use.

Another object of the present invention is that the lock card device is integrally formed, which can be produced by only one set of molds, thereby reducing the risk of damage and saving the production cost required for additional mold opening, thereby effectively saving. The overall cost and the simplification of the processing operation, and the card locking device is a separate component. If the card locking device is broken or damaged due to long-term use, it only needs to be separately replaced with the locking device to facilitate replacement and maintenance. purpose.

The restriction of the recess 41 on the side of the memory card 4 can further extract the memory card 4 to the outside of the opening 101 of the docking space 10, so that the buckle 231 of the latching portion 23 and the recess 41 of the memory card 4 are dislocated. And the memory card 4 is taken out from the docking space 10, thereby smoothly completing the action of the memory card 4 to withdraw the card.

The above memory card 4 can be a CFexpress card, a memory stack card (MS card), a secure digital card (SD card), a multimedia card (Multi-Media Card, an MMC card), a smart media card. (Smart Media Card, SM card), extreme digital video card (XD card), and a series of memory cards based on the improved design of the above memory card, such as mini digital security digital card (Mini SD) ), Micro Secure Digital Card (Micro SD) card and other specifications.

This creation has the following advantages:

(1) When the memory card 4 is inserted into the docking space 10 of the base 1, the latching portion 23 of the latching device 2 is buckled into the recess 41 of the side of the memory card 4 to be positioned. The memory card 4 is prevented from being loosened and pulled out. When the memory card 4 is to be removed from the docking space 10, the memory card 4 can be disengaged from the latching portion 23 only by pulling the triggering portion 24 of the card locking device 2. The limitation is that the memory card 4 can be easily pulled out from the docking space 10, thereby achieving the effect that the card is indeed and easily pulled out.

(2) The center of the inner wall surface of the accommodating groove 13 of the base body 1 is provided with an inwardly protruding stopper 131, and the base portion 21 of the locking device 2 is recessed with a stopper 131 placed in a block. The groove 212 can be positioned to pass through the groove 212 to have a good limit effect, so as to avoid the axial displacement of the card locking device 2 when the card 4 is inserted or retracted. Achieve stable use.

(3) The locking device 2 is integrally formed, so that the locking device 2 has a simple structure and can be produced by only one set of molds, thereby reducing the risk of damage and saving the production cost required for additional mold opening. Therefore, the overall cost is saved and the processing operation is simplified, and the locking device 2 is a separate component. If the locking device 2 is crushed or pulled for a long time to cause breakage or damage, it only needs to replace the locking device separately. 2 can be used to achieve the effect of easy replacement and maintenance.

The above detailed description is intended to illustrate a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents and modifications may be made without departing from the spirit of the invention.
