Description

card connector

technical field

The utility model relates to a connector, in particular to a card connector.

Background technique

With the continuous advancement of science and technology, various electronic cards are widely used in today's society, and as a connecting device for electronic cards, card connectors are correspondingly applied to electronic products. In order to stably hold the electronic card in the card connector, the card connector usually needs to be provided with a holding structure. An existing card connector includes an insulating body, and a card ejection mechanism is provided on one side of the insulating body. Holding the shrapnel can follow the sliding of the slider to complete the locking action.

However, when the above-mentioned card connector is locking the card by holding the elastic piece, the holding elastic piece tends to interfere with other structures of the card connector when sliding, or even be squeezed and deformed, so that the card locking function is lost.

Utility model content

The purpose of the utility model is to provide a card connector with reliable card locking function aiming at the defects existing in the prior art.

In order to achieve the above-mentioned purpose, the card connector provided by the utility model includes an insulating base body, and the insulating base body is provided with a card ejecting mechanism, several conductive terminals and a metal shell. A clamping elastic piece is fixed on the insulating base close to the card ejecting mechanism. The clamping elastic piece has an extension part, and one end of the extension part protrudes upward to form a clamping part.

As mentioned above, when the card connector of the present invention completes locking by holding the elastic piece, since the holding elastic piece is clamped and fixed on the insulating base, it does not move relative to other structures of the card connector, so it can avoid Interference and deformation with other structures, so the card locking function can be realized stably and reliably.
