Description

  The present invention relates to a connector, and more particularly to a card connector.

  The card connector shown in Patent Document 1 includes an insulating main body, a conductive terminal fixed on the insulating main body and used for mutual correspondence with the electronic card, a card ejection mechanism installed on one side of the insulating main body, and a tray on which the electronic card is placed. An accommodation space is established on the insulating body. The tray includes a main body and a lid positioned at the front end of the main body. A through hole is provided on one side of the lid. The main body of the tray is installed in the accommodation space. The card ejection mechanism includes a push bar and an execution part that presses against the push bar. When removing the electronic card, a needle is used to pass through the through hole of the lid, and the push rod is pushed up. The push bar pushes and moves the execution part, and pushes out the tray in which the electronic card is installed. When installing the electronic card, the electronic card is installed in the main body of the tray, and the tray is moved inward to the installation position.

  However, due to the tolerance when assembling the card connector and the circuit board and the tolerance of the card connector itself, the outer surface of the lid of the tray and the outer surface of the outer shell of the electronic device cannot be flattened. As a result, it is depressed inside or protrudes outside, and the appearance is uneven. The present invention has been made in view of the above-described drawbacks of conventional card connectors.

One end of the guide component 33 is installed in the insertion connection hole 319 and the opposite end is installed in the heart-shaped tank 133 in a slide shape.

  Subsequently, two sets of repositioning mechanisms 50 are installed at the front of the insulating body 10. The two sets of restoring mechanisms 50 project elastically on the front surface of the insulating body 10. Specifically, the movable parts 512 at the front part of the two contact parts 51 are installed in the first open tank 124 and the first open tank 137 in a slide shape. The contact base portions 511 at the front ends of the two contact portions 51 protrude from the front surfaces of the first side wall 12 and the first convex block 131, respectively. The position limiting part 513 and the fourth convex column 514 at the rear part of the two contact parts 51 enter the first storage tank 122 and the first storage tank 135, respectively. The two elastic parts 52 are installed in the first storage tank 122 and the first storage tank 135, respectively. One ends of the two elastic parts 52 are fitted on the first convex column 123 and the first convex column 136, respectively, and are in contact with the rear walls of the first storage tank 122 and the first storage tank 135. The opposite ends of the two elastic parts 52 are fitted on the fourth convex column 514 and are in contact with the rear surface of the position limiting part 513 of the contact part 51. The two contact parts 51 are pushed forward until the front surface of the position limiting part 513 contacts the front walls of the first storage tank 122 and the first storage tank 135 by the elasticity of the two elastic parts 52. The front surfaces of the two contact bases 511 are in contact with the inner surface of the outer shell of the electronic device 300.

  Furthermore, the tray 60 is installed in the accommodation space 15 from the position of the opening 301 so as to slide back and forth. The rear wall of the main body 61 comes into contact with the card eject part 313 of the slide block 31. The contact base 511 at the front part of the repositioning mechanism 50 comes into elastic contact with the rear surface of the lid part 62. The engagement support resilient piece 40 and the engagement support concave tank 64 are engaged to correspond. Finally, the shielding housing 70 is installed with a lid on the outside of the insulating body 10.

  As shown in FIGS. 1 to 5, when the electronic card 200 is set in the card connector 100 of the present invention, the tray 60 is pulled out and the electronic card 200 is set in the card storage tank 63. The lid body portion 62 of the tray 60 is pushed, and the tray 60 is moved backward. Both side walls of the main body portion 61 are in contact with the engagement support portion 421. Thereby, the elastic part 42 of the engagement support elastic piece 40 is compressed and deformed. The rear surface of the lid body portion 62 is in contact with the front surface of the contact base portion 511. The elastic part 52 is compressed and stores elastic energy. When the rear wall of the main body 61 comes into contact with the card ejecting portion 313 of the slide block 31, the slide block 31 is pushed and moved rearward along the first guide tank 113, the second guide tank 114, and the guide opening tank 115. Let The spring 32 is compressed and stores elastic energy. The guide component 33 moves rearward along the heart-shaped tank 133. The tray 60 is continuously moved backward until the rear wall of the tray 60 contacts the front surface of the third side wall 14. When the hand is released, the slide block 31 is pushed forward and moved by the elasticity of the spring 32. The guide component 33 contacts the engaging portion 134 along the heart-shaped tank 133 at one end in the heart-shaped tank 133. The engagement support part 421 of the engagement support elastic piece 40 and the engagement support concave tank 64 of the main body part 61 of the tray 60 are engaged and correspond to each other. The elastic part 52 contacts the contact part 51 elastically and moves it forward. The contact base 511 pushes the lid body 62 and moves the tray 60 to move forward until the upper and lower portions of the front surface of the contact base 511 contact the inner surface of the outer shell of the electronic device 300. The front surface of the lid 62 and the outer surface of the outer shell of the electronic device 300 are flat. The pins on the electronic card 200 come into contact with the contact portion 22 of the conductive terminal 20, and the tray 60 and the electronic card 200 are fixed.

  As shown in FIGS. 2, 4 to 6, when removing the electronic card 200, a force is applied backward to push the lid body portion 62 of the tray 60. The main body 61 of the tray 60 slides the slide block 31 by pushing it backward. The guide component 33 leaves the engaging portion 134 at one end in the heart-shaped tank 133. When the hand is released, the card eject mechanism 30 is pushed by the elasticity of the spring 31 until the front surface of the base 311 contacts the rear surface of the first convex block 131. Then, it is slid forward along the guide opening tank 115. The front surface of the stop portion 312 contacts the rear surface of the second convex block 132. At the same time, the main body 61 of the tray 60 is pushed and moved forward by the card ejecting part 313 of the card ejecting mechanism 30. The front end of the tray 60 protrudes to the front surface from the outside of the electronic device 300, and the electronic card 200 can be conveniently removed after the tray 60 is pulled out.

  As described above, in the card connector 100 of the present invention, the restoring mechanism 50 is installed by the front portion of the insulating body 10. The restoring mechanism 50 protrudes elastically on the front surface of the insulating body 10 and contacts the rear surface of the lid portion 62 of the tray 60 elastically. Accordingly, the tray 60 moves forward until the restoring mechanism 50 elastically contacts the inner surface of the outer shell of the electronic device 300. In this way, the front surface of the lid 62 and the outer surface of the outer shell of the electronic device 300 are evenly arranged, so that the appearance of unevenness such as indentation or protrusion outside does not appear.
