(a) Field of the Invention
The present invention relates to a memory card structure, and more particularly to a memory structure that has a simple structure, can be quickly assembled, will not fall off, and can reduce a manufacturing cost.
(b) Description of the Prior Art
As the advancement of modern technology, the prosperity of information, and the continuous changing of electronic products, memory cards have become a most convenient data storage product with a very broad application including a high technology product such as a digital camera, a digital camcorder, and etc.
However, as the specifications of memory cards on the current market are not standardized, there are a variety of memory cards with different sizes, such as an XD card, an MMSD card, a SD card, an MMC card, etc., according to different brands. In addition to having a compact size, these products are equipped with a high compatibility, a low cost, a high storage capacity, a fast transmission speed, and a confidentiality.
Since the memory cards are primarily used for data accessing and writing through electronic products or card readers, a write-protect device will be mounted on some memory cards to prevent the memory cards from being carelessly accessed or written in. The conventional write-protect devices primarily use a supersonic process to fix the body of memory cards, which often causes the body of memory cards unable to be sealed, and thus causes a fall off of the write-protect devices, thereby losing an original function of the write-protect devices.
Accordingly, the present invention includes a memory card body manufactured by a one-piece ejection molding process, with a slideway located at one side of the memory card. Latching slots are located at two sides at an upper and at a lower part of the slideway, and a write-protect device is mounted on the slideway. Latching hooks are located on the write-protect device at positions corresponding to the latching slots, so as to adjust a forward and backward position of the write-protect device on the slideway, and prevent the write-protect device from falling off through a latching function between the latching hooks and the slideway. In addition, the memory card can be assembled through a simple latching operation, thereby achieving objects of fast assembling, unable to fall off, and lowering a manufacturing cost.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

Moreover, to facilitate successfully latching the write-protect device 20 onto the exterior part of the slideway 12, guiding wedges 14 are installed at an upper and lower sides in a front part of slideway 12 respectively. Therefore, when the write-protect device 20 is being latched onto the slideway 12 by the means of the guiding slot 21, an opening of the guiding slot 21 can be expanded toward an upper and lower sides by the guiding wedges 14 at the upper and lower sides in the front part of slideway 12, so as to be latched onto the exterior part of the slideway 12. When the latching hooks 22 at a top of the guiding slot 21 are pushed to the positions of latching slots 13, the latching hooks 22 can be latched into the positions of the latching slots 13 with a elastic restoring force themselves, so as to firmly latch the write-protect device 20 onto the slideway 12 without easily creating a falling-off phenomenon.
Furthermore, as shown in
It is worth to mention that the memory card body of the present invention is primarily made by a one-piece ejection molding process, therefore it is very convenient in the manufacturing process, and thus can reduce a troublesome of human labor, a human error, and imperfection, thereby possessing effects of improving quality and productivity, and lowering a manufacturing cost. In addition, the write-protect device and the memory card body are assembled with a simple structure, thereby possessing an effect of fast assembling, and assuring not vulnerable to a falling off between the write-protect device and the memory card body.
Moreover, to facilitate adjusting a forward and backward position of the write-protect device 20 on the slideway 12, a saw-tooth slip-proof thread 23 or a raised part 24 as shown in
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
