The insulating body comprises a first flat plate base body and a second flat plate base body located below the first flat plate base body. The conductive terminal is provided with a butt joint part which protrudes into the accommodating space so as to be electrically connected with the corresponding electronic card. However, the upper receiving space and the lower receiving space of the stacked electrical connector are separated by the insulation body, so that the height of the electrical connector is increased, and the electrical connector is not favorable for the forward and reverse insertion of an electronic card and is inconvenient to use.
Please refer to the chinese patent No. 104425920, which discloses an electronic card connector capable of plugging a dual electronic card, comprising an insulating body, a conductive terminal fixed in the insulating body, and a drawer seat cooperating with the insulating body. The insulating body is provided with a containing cavity, and the drawer seat moves in the containing cavity. The drawer seat is provided with a first accommodating space and a second accommodating space. The conductive terminals comprise a first conductive terminal and a second conductive terminal which are matched with different electronic cards, and the first conductive terminal and the second conductive terminal are arranged corresponding to the first accommodating space and the second accommodating space respectively. The first accommodating space and the second accommodating space are arranged in a separated mode. The electronic card connector can simultaneously accommodate a plurality of electronic cards so as to ensure that an electronic product with the electronic card connector has a better size. However, the cover drawer seat is a first and a second accommodating space arranged along the front and back direction, which increases the length space of the electronic card connector occupying the electronic device, and the drawer seat is not beneficial to the positive and negative insertion, thus bringing inconvenience to use.
It is therefore desirable to provide a new electronic card connector and assembly thereof that overcomes the above-mentioned deficiencies.
