Card connector

The present invention relates to a card connector, and more particularly to a card connector with stable detection function.

In modern life, card connectors have been widely used in many electronic products (such as personal computers, mobile phones and other mobile devices). An electronic card connector including a shielding case, an insulative housing, a plurality of conductive terminals mounted on the insulative housing, and a contact are disclosed in the Chinese Patent Application Publication No. CN 102403591 A, issued on Apr. 4, 2012. Elastic spring piece. The contact and the elastic spring piece are mounted on the front end of the insulating body and are in a normally closed state. When the electronic card is normally inserted into the card connector, the elastic spring piece is elastically deformed backward to be disconnected from the fixed terminal to achieve the detection function. . Such a conventional normally closed structure detecting device is prone to disconnection and causes a failure of the detecting function, that is, a problem that the elastic spring piece cannot be reset and detected after the electronic card is pulled out. At the same time, the contacts of the electronic card connector and the elastic spring piece are completed by two presses, the process is complicated and the contacts may be warped to cause air welding.

Therefore, there is a need for an improved card connector to compensate for the above-discussed deficiencies in the prior art.

The main purpose of this creation is to provide a card connector in which the terminal can be stably contacted with the elastic detecting member.

The card connector of the present invention can be realized by the following technical solutions: a card connector, comprising an insulating body, a plurality of conductive terminals fixed on the insulating body, a shielding shell matched with the insulating body, and an elasticity fixed to the front part of the insulating body Detecting member, a receiving space for accommodating an electronic card is formed between the insulating body and the shielding shell, the conductive terminal includes a plurality of signal terminals and a fixed terminal integrally formed with the signal terminal, and the signal terminal and the terminal are embedded Formed on the insulative housing, the elastic detecting member protrudes forwardly on a front surface thereof to form a holding portion, and the holding portion is interference-fitted with the insulating body.

Compared with the prior art, the creation has the following functions: the fixed terminal of the card connector and the signal terminal are integrally stamped to prevent the welding of the fixed terminal to cause the air welding, and the elastic detecting component is provided with the wall facing the insulating body. The holding portion is interfered with the retaining wall to ensure stable contact with the fixed terminal.
