Description

Electronic card connector device

The utility model relates to an electronic card connector device, in particular to an electronic card connector device which is integrated with a circuit board and has a telecommunication start switch.

Existing electronic card connectors can generally be divided into plug-in type and contact type according to different telecommunication contact methods. The plug-in type means that the electronic card and electronic card connector are connected by male and female conductive pins for telecommunication contact. , such as US Patent No. 4,984,994. In the contact type, the telecommunications contact between the electronic card and the electronic card connector is carried out in a pressing manner, such as US Patent No. 5,013,255, Taiwan Patent No. 85205015, and the like. However, no matter which type of electronic card connector is used, one end of the conductive terminal must be electrically connected to the circuit board to transmit information between the computer host and the electronic card. With the development trend of thinner portable computers, not only the size of related components of the computer becomes smaller, but also the internal components of the computer tend to be recombined. As far as the contact electronic card connector is concerned, the thickness of the thinnest existing electronic card connector is 1.2mm, and the thickness of the electronic card is 2.0mm, which is about 3.2mm, which cannot be applied to a space of only 1.5mm (circuit board to height of the base case of the computer). In addition, when the existing electronic card is wrongly inserted into the electronic card connector due to the wrong direction, although the wrong information will be displayed on the computer after the operation of the host computer, such errors are due to the communication between the electronic card and the electronic card connector. The contact terminals are not in corresponding contact, so it will have a bad effect on the operation of the host, and easily cause damage to the host and its surrounding components.

The purpose of the utility model is to provide an electronic card connector device which can be inserted into a thin electronic card, and which is accurate and reliable for telecommunications.

The purpose of this utility model is achieved in this way: the electronic card connector device includes a base plate and an electronic card connector, wherein the base plate is provided with a receiving portion lower than the plate surface, and the electronic card connector includes an insulating body, which accommodates In the housing portion of the substrate, there are a number of housing slots for housing a relative number of conductive terminals; the insulating body is also provided with a power switch for controlling the power supply after the electronic card is inserted and positioned.

Compared with the prior art, the utility model has the advantage that its base plate is lower than the receiving portion of the plate surface, so that the insulating body can be sunken inside, thereby reducing its height in the main computer casing, and at the same time, it can be used by the power switch. The setting can provide the control effect of the electrical conduction of the electronic card and the conductive terminal of the electronic card connector after being correctly inserted.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.
