Description

  The present invention relates to an improved structure of a connector, and more particularly to a connector structure in which a memory card is firmly fixed and secured, signal transmission stability is ensured, and when the memory card is withdrawn, a hook pushes the memory card and is easily taken out.

With the development of information science and technology and digitalization, the development of storage facilities is rapid, and as the capacity of the storage facilities increases, the storage facilities are also downsized. Currently, digital products use conventional light, thin and small memory cards as storage facilities, and memory card connectors are a necessity for using memory cards.

However, since the volume of this type of memory card connector is small and the card insertion distance is short, the certainty of localization is difficult to understand, resulting in unstable data transmission. Therefore, when the equipment is inserted to a certain position by the touch switch, the facility activates the switch to start transmission of the memory card information. A known tactile switch has a normally open type or a normally closed type, and is composed of two or more different types of elements. The manufacturing process and assembly are complicated, and the cost is high.

  In addition, if the memory card is not firmly fixed after inserting the memory card, the memory card may be loosened and shifted due to shock or rocking, resulting in data transmission error or damage, or the conductive terminal and the memory card itself may be worn away. .

An object of the present invention is to provide an improved structure for a connector that improves the above-described problems.

  The improved connector structure of the present invention comprises an insulating frame, a set of conductive terminals, a card withdrawal mechanism, and a metal shield. A card withdrawal mechanism is provided on one side of the insulating frame to insert and remove the memory card. It has a conductive terminal in the insulating frame, one side of the conductive terminal has a normally open switch terminal, a hook on the slide block of the card withdrawal mechanism, and an elastic piece connected to it when the card is inserted The hook engages in the concave tank of the memory card, the memory card is fixed in position, and the signal transmission is stable without swinging. When the memory card leaves, the hook pushes the memory card and is easy to take out. .

  After inserting the memory card, it is possible to prevent the memory card from loosening and shifting due to impact or swinging, causing data transmission errors or damage, and preventing the conductive terminal and the memory card from being worn out. Also, the memory card can be easily removed. The advantage is obtained.

  1 and 2 are exploded and assembled views of the improved connector structure of the present invention. The connector improvement structure 1 includes an insulating frame 2, a set of conductive terminals 3, a slide block 4, a pull bar 5, an elastic piece 6, an elastic element 7, and a metal shield 8. The insulating frame 2 is used to mount the conductive terminal 3 and the card withdrawal mechanism. The card withdrawal mechanism installs the slide block 4 in the guide tank 22 on one side of the insulation frame 2. A track 41 is installed on the slide block 4, and slides in the track 41 when the slide block 4 slides with the pull bar 5. A hook 42 is installed on the side of the slide block 4 to connect the elastic piece 6. The elastic piece 6 is an iron piece. The metal shield 8 covers the insulating frame 2 and has a pull bar pressing piece 81 on the metal shield 8 so that the pull bar 5 is pressed by the track 41 and does not fall off. The plurality of memory card pressure pieces 82 apply pressure to the memory card 20, the memory card 20 and the conductive terminal 3 are in close contact, the side edge of the metal shield 8 has a plurality of holes 83, and the sheath 23 of the insulating frame 2. Combine with. The fixed terminal 21 is installed outside the insulating frame 2, welded onto the circuit board, the card withdrawal mechanism is provided, the memory card 20 is fixed, and the connector improvement structure 1 that is not interrupted during transmission is completed.

  Referring to FIGS. 3 and 4, in the card withdrawal mechanism, the sliding block 4 comes into contact with one end of the elastic element 7 and is provided with a contact part 43, and the elastic element 7 is a spring. The side of the slug 4 has a hook 42 to which the elastic piece 6 is coupled, and a holding space 40 is formed between the hook 42 and the slug 4 by the elasticity of the elastic piece 6. The front end of the hook 42 has a convex oblique angle 45 and a guiding oblique angle 44, one side of the insulating frame 2 has a guiding tank 22, and the sliding block 4 and the guiding oblique angle 44 are slid. It has a wide portion 220 and a narrow portion 221.

  As shown in FIGS. 3 to 6, the slide block 4 and the guide angle 44 of the card withdrawal mechanism slide in the guide tank 22 of the insulating frame 2, and when the slide block 4 slides in, the hook 42 is elastic. When the bevel angle 44 is engaged with the wide portion 220 of the guide tank 22 by the elasticity of the piece 6 and the container 40 has the storage space 40 between the hook 42 and the slide block 4, the slide block 4 slides outward. The guide angle 44 of the hook 42 is engaged with the narrow portion 221 of the guide tank 22, and the hook 42 is pushed by pressure and is placed in the storage space 40.

  As shown in FIGS. 7 to 9, when the memory card 20 is positioned, the guide angle 44 of the hook 42 slides along the guide tank 22, and slides into the narrow portion 220 of the guide tank 22. Is ejected and fixed to the concave tank 200 of the memory card 20, and the memory card 20 is stably fixed. When the memory card 20 is withdrawn, the memory card 20 is pushed in, the elastic element 7 is compressed, the elastic force of the elastic element 7 pushes the card withdrawal mechanism forward, and the convex oblique angle 45 of the hook 42 is caused by the top end of the guiding tank 22. The hook 42 detaches the concave tank 200 of the memory card 20, the oblique angle 22 of the hook 42 slides into the narrow portion 221 of the conductive tank 22, and the hook 42 is received in the storage space 40. Forty-two contact portions 43 push the memory card 20 forward to facilitate removal.
