The present invention relates to an electrical connector, and more particularly to an electrical connector for electrically connecting an electronic card.

Generally, the electrical connector of the inserted electronic card is provided with a detection switch to detect whether the electronic card is inserted. For example, the Taiwan Patent Publication No. TW201223033 (corresponding to the Chinese Patent Publication No. CN102480068, US Patent Publication No. US20120129370, Japanese Patent Publication No. JP2012114089) discloses a drawer type card connector whose detection switch is provided by a switch terminal provided on the insulative housing, and The switch piece is integrally formed with the shielding shell. The switch piece is horizontally cantilevered on one side of the shielding shell and is elastically displaced to form an electrical connection with the switch terminal. After the tray is inserted, the switch piece is pushed to separate from the switch terminal to form an open circuit, thereby detecting whether the tray is placed.

However, since the switch piece is horizontally cantilevered and integrally formed with the shield case, the structure is complicated and it is less easy to manufacture. If the switch piece is elastically tired or defective, the entire shield case must be disposed of, which increases the manufacturing cost. In addition, the insulating body is provided with a conductive terminal and a switch terminal at the same time, since the conductive terminal must be located at a specific position to correspond to the conductive pad of the electronic card, and the switch terminal must correspond to the switch piece, so that the conductive terminal is separated from the switch terminal by a distance, and the insulating body is Covering the range of the conductive terminals and the switch terminals requires a large area, but in the trend of thinning, the insulating body has a large area and a small thickness, that is, it is easy to cause warpage and reduce the production yield.

Accordingly, it is an object of the present invention to provide an electrical connector having an easy to manufacture detection switch and having a better production yield.

Therefore, the electrical connector of the present invention comprises an insulating unit, a shielding shell, a plurality of conductive terminals and a detecting switch. The insulating unit includes a main body and a mounting seat separated from each other. The shielding shell and the insulating unit together define an accommodating space and has a cover portion. The conductive terminals are disposed on the body of the insulating unit. The detecting switch includes an abutting portion formed on the shielding shell and a detecting terminal. The detecting terminal is disposed on the mounting seat of the insulating unit, and has a fixing portion embedded in the mounting seat, a resilient arm extending from the fixing portion toward the abutting portion, and a fixing portion The welded portion of the mount extends in a direction opposite to the cover portion. The elastic arm has a pushing portion that protrudes convexly toward the accommodating space, and a contact portion formed at an end of the elastic arm to contact the abutting portion. The pushed portion can be pushed by the object accommodated in the accommodating space to change the electrical connection state between the contact portion and the abutting portion. The object for pushing the push portion may specifically be a tray or an electronic card.

The function of the present invention is that the detecting terminal of the detecting switch is fixed to the mounting seat, and the mounting seat is separated from the body provided with the conductive terminal, so that the detecting terminal and the mounting seat can be modularized, not only the insulating unit It is easy to manufacture and is not easy to warp, and the modular detection terminals and mounts can be placed on either side of the main body according to the needs of use.
