Description

Connector anti-fly card device

technical field

The utility model relates to an anti-flying card device for a connector, in particular to a connector in which the rotating friction assembly provided by the card ejecting device can form friction with the metal cover or the body to slow down the ejection force of the card ejecting device from 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 purpose of this utility model is to provide a rotating friction assembly provided by the card ejecting device that can form friction with the metal cover or the body, which can slow down the ejection force of the card ejecting device to the outside of the slot, so as to prevent the memory card from being ejected. fly outside the connector.

In order to achieve the above purpose, the connector body of the utility model is provided with a slot for at least one type of memory card to be inserted. The opening at the top of the slot is covered with a metal cover, and one side of the slot is provided with a card ejector. device; wherein, the card ejecting device is provided with a rotating friction assembly, and the rotating friction assembly can move synchronously with the card ejecting device to form a rotating action, and can contact the metal cover or the body to form a friction effect.

Wherein, the rotating friction assembly has a central shaft column and a plurality of protrusions arranged around the periphery, and the metal cover or body is provided with a plurality of grooves corresponding to the movement path of the card ejecting device, each groove and the protrusions Correspondingly, when the memory card is ejected, the card ejecting device drives the rotating friction assembly to move and rotate at the same time when the card ejecting device moves. The contact friction action with the groove can slow down the ejection force of the card ejecting device to the outside of the slot, so as to prevent the memory card from being ejected out of the connector.

The beneficial effects of the utility model are: a connector anti-flying card device can be obtained, especially means that the rotating friction assembly provided by the card ejecting device can form friction with the metal cover or the body 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.
