Description

Structural Improvement for Preventing Carding and Falling of Connectors

technical field

The utility model relates to a structural improvement of a connector that prevents the card from falling off, especially refers to a connector that can form a friction effect with the card ejecting device through the push piece provided by the metal cover, so as to slow down the ejection force of the card ejecting device to the outside of the slot Anti-snapping structure.

Background technique

In recent years, memory cards (or flash memory cards) have been widely used in information appliances, personal computers or portable digital products (hereinafter collectively referred to as electrical devices).

In addition, electrical devices that generally use memory cards as storage media, such as digital cameras, PDAs, digital walkmans, etc., basically still use specific memory cards as data storage media, and then connect with the host computer for memory. The reading and storage of the card, however, when the memory card is connected to the host computer, the connector must be used as the transmission medium to facilitate the reading and storage of the host computer.

However, the connection relationship between the traditional memory card and the connector is manually plugged in and out, which causes a lot of inconvenience in operation; then the card is returned by using the push rod method, or the method of repeatedly pressing the memory card (commonly known as Push-Push) ) and other designs are designed to provide users with convenience in operation. For example, the memory card ejection device in Taiwan, China Announcement No. 547834 is a typical push-push card ejection design, which basically uses the memory card to be inserted into the connector to move the sliding seat, such as "heart-shaped". The "heart-shaped" card ejection path and the pulling force of the elastic components produce positioning and restoration effects. Since this part of the technology has been used for many years, it will not be described here.

With the above-mentioned Push-Push card ejection design, although the problem of inconvenient operation for the user is solved, the memory card is thrown out of the connector due to the excessive force of the elastic component in the card ejection device. This situation is likely to cause wear and damage to the memory card.

Utility model content

Therefore, the utility model provides a push piece provided by the metal cover, which can form a frictional effect with the card ejecting device, and can slow down the ejection force of the card ejecting device to the slot, so as to prevent the memory card from being ejected from the slot. outside the connector.

In order to achieve the above-mentioned purpose, the connector body of the present invention is provided with at least one slot for inserting the memory card, the opening at the top of the slot is covered with a metal cover, and a card ejection device is provided on one side of the slot; Wherein, the metal cover is provided with a pushing piece corresponding to the travel path of the card ejecting device, and the pushing piece can be in contact with the card ejecting device and can form a frictional effect on the card ejecting device.

Wherein, the card ejecting device at least includes: a sliding seat pushed by the elastic component, a card ejecting guide rod and a card ejecting path, the card ejecting guide rod and the card ejecting path are arranged on the outer surface of the body, and the card ejecting guide One end of the rod is fixed on the sliding seat, and the other end can move in the card ejection path, and the push-off piece is arranged on the travel path of the metal cover corresponding to the slide of the slide seat to the outside of the slot, and the push-off piece moves from the metal cover toward the outside of the slot. The slot is bent to form a pushing part, and when the memory card is withdrawn, the pushing part can be used to contact the sliding seat to form a friction effect.

The beneficial effects of the utility model are: a structure improvement for preventing the card from falling off of the connector can be obtained, especially means that the push piece provided by the metal cover can form a frictional effect with the card ejecting device to slow down the ejection of the card ejecting device from the slot. The anti-jamming structure of the connector with external pop-up force.

Detailed ways

The structural improvement of the connector of the utility model to prevent card falling off, please refer to Figure 1, the connector body 1 is provided with at least one slot 11 for inserting the memory card 4, and the opening at the top of the slot 11 is covered with a There is a metal cover 2, and a card ejecting device 3 is provided on one side of the slot 11, please refer to Fig. 2 and Fig. 3 at the same time, the card ejecting device 3 at least includes: Card ejection guide rod 33 and a card ejection path 34, a card block 321 is formed at an appropriate position of the slide seat 32, its card ejection guide rod 33 and card ejection path 34 are arranged on the outer surface of the body 1, and its card ejection guide rod 33 One end is fixed on the sliding seat 32 , and the other end can move in the card ejection path 34 .

The key point of the utility model is that the metal cover 2 is provided with a pushing piece 21 corresponding to the travel path of the card ejecting device 3, and the pushing piece 21 is arranged on the metal cover 2 and slides outwards to the slot 11 corresponding to the sliding seat 32. On the moving path, as shown in the embodiment of this figure, the pushing piece 21 is integrally bent toward the slot 11 by the metal cover 2 to form a pushing portion 211 .

When the memory card 4 is intended to be inserted into the slot 11, the positioning notch 41 of the memory card 4 is placed on the block 321 of the slide seat 32, as shown in Figures 4 and 5, and the memory card 4 simultaneously pushes the slide seat 32, and use the elastic component 31 to move toward the inside of the slot 11, and at the same time make the card ejection guide rod 33 linked with the slide seat 32 move in the card ejection path 34, as shown in Figure 6A and B, and finally the card ejection guide rod One end of 33 is firmly fixed in the hook portion 341 of the card ejection path 34 , so that the memory card 4 is firmly inserted into the slot 11 .

When in the above-mentioned state of inserting the card and intending to eject the card, the memory card 4 can be pushed, as shown in FIG. card, and the restoring force of the elastic component 31 will move the slide seat 32 to the outside of the slot 11, as shown in Figure 8 and Figure 9, and at the same time the memory card 4 will be withdrawn from the connector, and then the slide seat 32 will move to the slot 11 In the outer moving path, since the pushing part 211 of the pushing piece 21 is in contact with the sliding seat 32 and forms a friction effect, the force of the elastic component 31 pushing against the sliding seat 32 to pop out of the slot 11 can be slowed down, which can effectively prevent The memory card 4 is ejected out of the connector.

Furthermore, the pushing piece can also be a piece that is additionally installed on the body or the metal cover, as shown in the embodiment shown in FIG. 10 and FIG. 11 , the pushing piece 21 forms a fixing portion 212 that can be snapped into the body 1 , and the body 1 also forms a slot hole 12 for the fixing part 212 to snap into, and the fixing part 212 is used to snap into the slot hole 12 , so that the pushing piece 21 is assembled and positioned on the body 1 .

As mentioned above, the utility model provides a connector with a more feasible anti-jamming structure, so an application for a new patent is submitted according to law; however, the above implementation description and drawings are the preferred implementation of the utility model For example, it is not intended to limit the present utility model, therefore, all similar and identical structures, devices, features, etc. of the present utility model should belong to the creation purpose of the present utility model and within the scope of the patent application.
