Description

Technical Field

[0001] The utility model belongs to the technical field of memories, and particularly relates to a plug-in memory card. Background Art

[0002] A card reader is a special device. It has a slot for inserting a memory card and a port for connecting to a computer. After inserting a suitable memory card into the slot, connecting the port to the computer and installing the required driver, the computer regards the memory card as a removable memory, so that the memory card can be read and written through the card reader.

[0003] During the use of current memory cards, they are often inserted and removed. After multiple insertions and removals, the metal contacts in the memory will scrape off the medium on the metal contacts of the memory card, affecting data transmission and easily causing problems of card reading failure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plug-in memory card to solve the problems that during the use of current memory cards, they are often inserted and removed, and after multiple insertions and removals, the metal contacts in the memory will scrape off the medium on the metal contacts of the memory card, affecting data transmission and easily causing problems of card reading failure.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a plug-in memory card, including a memory main body and a memory card. The memory main body includes a memory housing. An insertion slot is formed on one side surface of the memory housing. The memory card is in plug-in fit with the insertion slot. A notch groove is formed on one side surface of the memory card. A groove is formed on the inner bottom surface of the memory housing. A matching spring is fixedly connected inside the groove. One end of the matching spring is fixedly connected with a linkage block. One end of the linkage block is arranged in the groove and is in sliding fit with it. A connecting plate is fixedly connected to one side surface of the linkage block. The connecting plate is arranged on one side of the insertion slot and is in sliding fit with the insertion slot. A through groove is formed on the surface of the connecting plate. A positioning spring is fixedly connected to the inner wall of the through groove. One end of the positioning spring is fixedly connected with a positioning block. One end of the positioning block is arranged in the through groove and is in sliding fit with it, and the other end is in clamping fit with the notch groove.

[0007] A hinge rod is fixedly connected between the inner walls of the card slot. A matching plate is hinged to the periphery of the hinge rod. The matching plate is arranged below the memory card. One side of the upper surface of the matching plate is fixedly connected with a data block. A plurality of groups of metal contacts are installed inside the data block. A plurality of groups of metal contact pieces are arranged on the bottom surface of the memory card. One end of the metal contact is in contact with the metal contact piece. The other side of the upper surface of the matching plate is fixedly connected with a matching rod. One end of the matching rod is in contact with one side of the bottom surface of the memory card.

[0008] A slot is opened on one side surface of the memory housing. The slot is arranged on one side of the card slot. A guide rod is fixedly connected inside the memory housing. The guide rod is arranged between the inner wall of the memory housing and the linkage block. A connecting rod is slidably connected to the periphery of the guide rod. One end of the connecting rod is fixedly connected with the linkage block, and the other end is arranged in the slot and is slidably matched with it.

[0009] A USB interface is installed at one end of the memory housing.

[0010] The utility model has the following beneficial effects:

[0011] By setting the memory main body and the memory card, when the memory card is inserted into the card slot, the memory card presses the positioning block. Under the action of the positioning spring, the positioning block moves. As the memory card is inserted, the positioning block is clamped and matched with the notch groove under the cooperation of the positioning spring, so as to fix the memory card in the memory. And as the memory card is inserted, one end of the memory card presses down the matching rod. Under the action of the hinge rod, one end of the matching plate is lifted, so that a plurality of groups of metal contacts are in contact with the metal contact pieces on the memory card, ensuring the normal use of the memory card; pressing down the connecting rod, which drives the linkage block to move down under the cooperation of the guide rod, compresses the matching spring, and then drives the connecting plate to move down through the linkage block, and then drives the positioning block to move down, releasing its restriction on the memory card, so that the memory card can be taken out from the card slot. As the memory card is removed, the matching rod is not stressed, and the end of the matching plate with metal contacts drops, so that the metal contacts are no longer in contact with the metal contact pieces, effectively avoiding the medium of the metal contact pieces being scraped off by the metal contacts.

[0012] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
