The card reader connector 100 according to the present invention described with reference to FIGS. 1 and 2 may be configured with two or more layers, which will be described with reference to FIGS. 3 to 5.

3 is a view illustrating a state in which a connector and a connector are coupled, FIG. 4 is a view illustrating a state in which two connectors are coupled to a cover, and FIG. 5 is a perspective view of a connector having a two-layer structure according to the present invention.

That is, as can be seen in Figure 3 in the state in which the main terminal 110, the outer terminal 170 portion of the upper connector 100 is formed short, the corresponding terminal 170a portion of the lower connector 100a is formed long Two connectors (100, 100a) are folded through the main body information 120. Then, as shown in FIG. 4, when inserted into the cover 190 and coupled, the connector 100b having a two-layer structure as shown in FIG. 5 may be formed. In addition, if necessary, it is possible to make a multi-layered structure of three or more layers by stacking as many connectors as necessary in the same manner as above and combining them with a cover. Of course, the bottom portion of the main body 110 corresponding to the main body information 120 is preferably formed with a groove into which the main body information 120 can be inserted.

In the state as shown in FIG. 2 or FIG. 5, the outer ends of the terminals 170 and 170a are soldered to the substrate.

With the above-described connectors 100, 100a, 100b installed on the board of the card reader A detaching process of the memory card 10 will be described with reference to FIGS. 1 to 5 as follows.

That is, when the memory card 10 is sufficiently inserted into the holder 150 in the accommodating part 111 through the opening 113, the card latch 157 holds the memory card 10 so that the memory card 10 is not detached. In this manner, when the memory card 10 is further pushed inward while the memory card 10 is mounted on the holder 150, the memory card 10 enters the inside of the holder 150.

In the state where the holder 150 is sufficiently inward, the latch 156 of the holder 150 is caught by the locking jaw 183 of the holder latch 180. Accordingly, even if the holder 150 is subjected to the force of the elastic member 160, the holder 150 is stopped at the correct position without moving forward. In this state, each of the contacts of the memory card 10 is in contact with the terminals 170 to make an electrical connection. In this state, the card reader may read and play back the data recorded in the memory card 10 or input other data into the memory card 10.

Push the button 130 by hand to release the memory card 10 from the connectors 100, 100a, and 100b, or insert the tip of the ballpoint pen into the groove 136 if it is difficult to do it with your hand. Push button 130 inward. Then, the button 130 is pushed inward, and accordingly, the inclined surface 132 formed at the inner end of the button 130 pushes the end of the holder latch 180 outward. In this process, the latch 156 of the holder 150 that is caught on the locking jaw 183 of the holder latch 180 is separated from the locking jaw 183. At the same time as the latch 156 is separated from the latching jaw 183, the elastic member 160 pushes the holder 150 outward. Accordingly, the memory card 10 is moved outward by the holder 150. When the holder 150 advances over a certain distance, one side of the holder stops. The jaw 117 is stopped and stopped, and when the memory card 10 is pulled outward in this state, the end of the card latch 157 is pushed outward and the memory card 10 is separated from the holder 150.

As described above, the card reader connector according to the present invention allows the holder on which the memory card is mounted so that the memory card can be positioned at the correct position. Therefore, the terminal is correctly connected to the terminal. Since it moves to a position that is easy to remove, it is not only easy to detach and can be made into a multilayer structure of two or more layers, and its use is excellent.
