3 is a schematic structural view of a second preferred embodiment of the secure digital card slot structure of the present invention.

Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention is a secure digital card slot structure 100. The secure digital card slot structure 100 is applied to a portable electronic device (not shown) such as a mobile phone. It includes a slot 10, an antenna 20, and a circuit board 40. The antenna 20 and the slot 10 are integrated to form a complete rectangular box 30 for housing a secure digital card (not shown). The circuit board 30 is the above portable electronic device In one part of the body circuit, the slot 10 and the antenna 20 are mounted on the circuit board 40 to establish the necessary electrical connection.

The slot 10 can be a conventional secure digital card slot that can be used to accommodate a commonly used 32mm x 24mm secure digital card. In the present embodiment, the slot 10 is substantially in the shape of a rectangular box, and is made of a conductive material such as metal or the like, in which a circuit (not shown) corresponding to the secure digital card is formed. A first surface 101 of the slot 10 is fixedly mounted on the circuit board 40 and electrically connected to the circuit board 40. When the security card is inserted into the slot 10 through the opening (not shown) provided on the side of the slot 10, the slot 10 can be electrically connected to the circuit board 40, thereby implementing corresponding data storage and reading. Features. When the slot 10 is exposed to the outer second surface 102, a notch 12 having a size and shape matching the antenna 20 is formed by hollowing out for receiving the antenna 20.

It can be understood that the notch 12 can theoretically be opened on any part of the surface of the slot 10; in practical applications, in order to obtain better communication effects, it is generally opened on the surface of the exposed portion thereof, such as this The second surface 102 in the embodiment.

The antenna 20 is a conventional planar antenna. For example, a planar inverted-F antenna or other shaped microstrip antenna used in the embodiment can be used for transmitting and receiving wireless signals by the portable electronic device. The material of the antenna 20 may be the same metal material or other metal material as the socket 10, and the edge thereof is provided with an insulating tape 21 formed by a conventional method such as applying an insulating varnish. The antenna 20 is spliced into the notch 12 of the slot 10, and has a shape that completely coincides with the notch 12, so as to form a complete box 30 together with the slot 10 to more stably accommodate the secure digital card and the circuit. The board 40 establishes the necessary electrical connections such as grounding and feeding.

When manufacturing, the slot 10 and the antenna 20 can be separately manufactured by a conventional method such as molding, and then spliced together to form a complete case 30, and then the case 30 is fixedly mounted on the circuit board 40, and The circuit board 40 and the antenna 20 are respectively connected to the slot 10 and the antenna 20 to establish necessary data transmission, grounding, and feeding, and the socket 10 and the antenna 20 can be used according to a conventional method.

In addition, since the socket 10 is made of a conductive material, in order to save materials and simplify the manufacturing process, a complete case 30 can be formed according to a conventional method, and then according to a predetermined shape (for example, an inverted F shape in this embodiment). A corresponding portion is divided from the arbitrary position of the casing 30 as the antenna 20, and the remaining portion after the division is used as the slot 10. The insulating tape 21 is formed on the edge portion of the antenna 20 by a conventional method such as applying an insulating varnish, and the antenna 20 is spliced back to the position before the division on the slot 10, and re-spliced into a complete case 30. The function of the insulating tape 21 is to insulate the slot 10 from the antenna 20 to prevent the antenna 20 from changing its radiation characteristics by short-circuiting with the slot 10. Finally, the box body 30, which is formed by the slot 10 and the antenna 20, is fixedly mounted on the circuit board 40, and the circuit board 40 is respectively connected with the slot 10 and the antenna 20 to establish necessary electrical properties according to a conventional method. By connecting, the slot 10 and the antenna 20 can be used in accordance with conventional methods.
