Electronic card connectors of electronic devices are installed directly on a circuit board in the early, so a housing of the electronic device must be removed firstly to place an electronic card in the electronic card connector. While electronic card connectors of some electronic devices, such as mobile phones, are installed under batteries, in this case, the housing and the battery of the mobile phone all need to be removed sequentially, and then the electronic card can be placed in the electronic card connector, said removing and placing will bring a lot of trouble to consumers.
In order to comply with the development trend of simplifying electronic device, a drawer card connector appears recently, it usually includes an insulation body, multiple conductive terminals positioned at the insulation body, and a covering housing masking the insulation body. The insulation body and the covering housing coordinate with each other so as to form an accommodating space therebetween, and a sliding holder is accommodated in the accommodating space. An exiting mechanism is fixed on the insulation body for sliding the sliding holder forward and backward in the accommodating space. The exiting mechanism further includes a pop-up element, a pivoting element and a pushing rod, wherein, the pop-up element and the pivoting element are located at back of the insulation body, and at least part of the pop-up element exposes in the accommodating space and presses against the sliding holder elastically. The pivoting element has an actuating portion and a pushing portion, the pushing rod extends forward and backward at a side of the insulation body, a back end of the pushing rod presses against the pushing portion, a leading end of the pushing rod is extended to the front of the accommodating space.
The electronic device has an accommodating cavity defined at a side thereof, and the accommodating cavity has an opening communicating with outside, the drawer card connector is installed in the accommodating cavity, the electronic card can be placed in the drawer card connector without removing the housing of the electronic device. Just need pushing the leading end of the pushing rod with a tool that firstly enters into the opening, and the leading end of the pushing rod drives the back end of the pushing rod to press against the pushing portion backward, and then the pushing portion drives the actuating portion to rotate and thereby press against the sliding holder forward. Meanwhile, the pop-up element applies a forward thrust to the sliding holder, thereby the sliding holder exits outward, and then the electronic card can be put in the sliding holder, finally the sliding holder is pressed backward into the accommodating space, and the sliding holder can be positioned therein.
Though the exiting function of the drawer card connector is easy, which can overcome the removing and placing problem of the conventional electronic card connector, but it doesn't comply with the development trend of miniaturization and low cost for electronic devices nowadays, that is because the exiting mechanism includes three separate elements, the pop-up element, the pivoting element and the pushing rod, which are disposed at back of and a side of the insulation body respectively, and occupy much space of the insulation body, thereby prevent miniaturization progress of the drawer card connector. In addition, the processes of manufacturing and assembly are complex, which increase the cost of manufacturing, thereby fail to achieve the goal of low cost.
Hence, it is desired to provide a new card connector to overcome the above-mentioned drawbacks.
