Description

Card connector {CARD CONNECTOR}

The present invention relates to a card connector, and more particularly, to a card connector enabling insertion / ejection of an IC card through a push-push operation.

An IC card is an integrated card, and is a next-generation card that replaces a magnetic card. As the name suggests, it features a semiconductor-based integrated circuit. In a broad sense, it's a card with a tiny computer. In addition to the IC card, it is also called a smart card. The IC card does not damage the data when it comes in contact with the magnet, and can provide more various functions than the magnetic card, and has excellent security and durability.

IC cards are divided into contact type and contactless type depending on the internal structure as well as the method of use. The contactless IC card with a metal pattern on the front of the card is the most common form of IC card. The contact IC card works only when the metal pattern of the card and the terminal of the input device are tightly contacted, so it is highly secure and can transmit relatively large amounts of data reliably. Credit cards and cash cards mainly use contact types, and the USIM card, a personal information storage device installed in a mobile phone, also uses the principle of a contact IC card.

The contactless IC card has a module and an antenna capable of wireless communication in the card. It detects RF (radio frequency) signals around the card, exchanges data, and communicates with input devices. Depending on the type of card, it can be used as a way to make a rubbing with an input device. Security is somewhat lower than contact IC card because communication is performed without contacting the terminal of input device, but it can be used quickly. It is a typical use case for a transportation card.

There are also cards with several functions. Cards with both contact and contactless IC cards are known as hybrid cards or combination cards. The two terms are used almost synonymously, but it is generally classified as a hybrid card when a contact IC and a non-contact IC exist inside the card, and a combination card when the two ICs are integrated. A card that combines the functions of a magnetic card and an IC card is also called a hybrid card.

There are various types of terminals including a card connector for inserting an IC card, such as a general credit card reader, a smart card socket of an IPTV set-top box, a POS mobile device, a household POS device, an access card reader, and a high pass terminal.

Meanwhile, credit card merchants are required to install IC card terminals by July 2018. The payment for the card is a magnetic card that scratches the card and the IC card that is plugged into the terminal. Until then, you can use MS type or MS / IC card terminal, but from July 2018, only IC card terminal can be used. As the IC card terminal for inserting the card into the terminal is mandatory as mentioned above, the importance of the card connector used in the terminal is also increasing.

IC card terminal is designed to insert card and not insert card completely for easy insertion / ejection.

For example, a high pass terminal uses a high pass dedicated card or postpaid check / credit card. The connector of the existing high-pass terminal simply has a space for insertion / ejection, so the user has to push the terminal until the terminal is contacted and there is a separate notification from the terminal or the card can no longer be pushed.

Most of the high-pass terminals on the market pointed out that the card is not pushed all the way down as a cause of malfunction. The description of the High Pass terminal also tells you to insert the card all the way with a separate warning.

As described above, the IC card terminal is designed so that the width of the connector is made shorter than the width of the card in order to prevent the card from being inserted, which causes the malfunction. This manufacturing feature makes it easy for the user to grasp the card by hand and push it in to insert it completely and to remove it again.

However, since the card is exposed to the outside, the card may be removed due to carelessness or other factors of the user, which may damage the card terminal or the card. In addition, in view of the trend toward ultra-thin card connectors, it may be difficult to design a compact IC card terminal.

An object of the present invention is to provide a connector for preventing a malfunction of a terminal caused by a card connector by adopting a push-push operation method to a connector of a terminal using an IC card. .

The card connector according to the present invention includes a main body having a contact terminal, a guide line and a guide groove, a cover covering the main body to form a card insertion space, a spring, a space into which the spring is inserted, a protrusion and a fixing groove, And an adjustment pin disposed inside the slider and both ends bent at right angles, one end of which is disposed in the fixing groove of the slider and the other end of which is disposed on the guide line of the main body.

When the protrusion of the card connector is pushed in the first direction due to the insertion of a card, the spring of the slider is compressed and the slider moves along a section formed inside the main body, while the slider moves. The other end moves along the guide line and is fixed to the guide groove.

When the protrusion is pushed in the first direction together with the inserted card, the other end of the adjustment pin is disposed in the guide line out of the guide groove, and the slider is restored in the second direction by the spring. While the other end of the adjusting pin reaches the starting point of the guide line is characterized in that the card is discharged.

The protrusion is formed inside the card insertion space and adjusts the position of the inserted card such that the terminal portion of the inserted card abuts against the contact terminal when the other end of the adjusting pin is fixed to the guide groove.

The main body has a spring seat coupled with the spring of the slider, and the other end of the adjustment pin is fixed to the guide groove when the slider touches the surface on which the spring sheet is formed.

The guide line may include a first guide line for guiding the other end of the adjusting pin toward the guide groove; And a second guide line for moving the other end of the adjusting pin out of the guide groove toward the start point of the first guide line.

The depth in which the first guide line is formed is deeper than the depth in which the second guide line is formed.

The cover may include a card pressing plate which presses the inserted card so that the inserted card is fixed in contact with the contact terminal in the card insertion space.

The cover may include a contact terminal groove corresponding to a portion where the contact terminal protrudes when the card insertion space is formed to cover the main body.

It is characterized in that it further comprises a slider cover coupled to the bottom of the main body so that the slider does not leave the section when the slider moves in the section formed inside the main body.

The slider cover is an adjustment pin pressing plate for pressing the other end of the adjustment pin so that the other end of the adjustment pin does not leave the guide groove when the other end of the adjustment pin is moved along the guide line and fixed to the guide groove Characterized in that provided.

The IC card terminal according to another embodiment of the present invention is characterized by using any one of the card connector.

The present invention can prevent the malfunction of the IC card terminal by using a push-push mechanism in the card connector of the IC card terminal to accurately insert and eject the card.

The spring insertion space 142 is formed from the space above the fixing groove 141 to the uppermost end.

Referring to FIG. 5C, the figure is a cross-sectional view of the slider 140 viewed from the side as A-A '. The fixing groove 141 is recessed to a depth as long as one end of the adjusting pin 150 can be fixed. The spring insertion space 142 is not the length of the entire spring 160, but the spring 160 to compress the spring 160 when the slider 140 moves inward to contact the surface on which the spring sheet 125 is formed. It is formed by a length shorter than the length of. Therefore, even if the spring 160 is completely inserted into the spring insertion space 142, a portion of the spring 160 is exposed to the outside of the slider 140.

Figure 6a is a perspective view showing a state in which the card is not inserted in the embodiment according to the present invention and a view showing the inside of the main body.

Referring to FIG. 6A, the front surface of the main body 120 is shown without the card 10 inserted. An enlarged view of the portion indicated by the dotted line shows the inside of the main body 120. The drawing inside the main body 120 shows when the same area is seen from the rear of the main body 120.

When the card 10 is not inserted, the slider 140 is in contact with the surface on which the guide lines 122 and 123 are formed. When the slider 140 is inserted into the main body 120, the spring 160 is inserted in a slightly compressed state, so that the slider 140 may be applied to the elastic force of the spring 160 to be restored even when the card 10 is not inserted. By the force pushed outward.

The adjusting pin 150 is located at the start of the first guide line 122. The starting point is a starting point of the movement of the adjusting pin 150 to move from the first guide line 122 to the guide groove 124 and at the same time the operation stops past the second guide line 123 in the guide groove 124 Corresponds to the arrival point.

Referring to FIG. 6B, in the state in which the card 10 is inserted, unlike the FIG. 6A, the spring 160 is not exposed to the outside from the front surface of the main body 120, and the protrusion 143 is formed on the surface on which the spring sheet 125 is formed. It is completely in touch. As the projection 143 moves to the surface, the chip portion of the card 10 is positioned where it can contact the contact terminal 121.

Inside the main body 120, the other end of the adjustment pin 150 is fixed to the guide groove 124 passing through the first guide line 122. The slider 140 comes into contact with the surface on which the spring seat 125 is formed, which is the innermost surface, and the spring 160 is compressed to the maximum.

Figure 7a is an enlarged view of the main part of the main body for explaining the movement of the adjustment pin to the guide groove in one embodiment according to the present invention.

Referring to FIG. 7A, as the card 10 is inserted, the protrusion 143 is pushed inward. As the slider 140 moves inward, the adjusting pin 150 starts from the starting point on the first guide line 122 and reaches the guide groove 124. The reason why the adjusting pin 150 first moves on the first guide line 122 instead of the second guide line 123 is that the first guide line 122 and the second guide line 123 are formed at a difference in depth. Is caused. The first guide line 122 is formed deeper than the second guide line 123 so that the other end of the adjusting pin 150 starting from the starting point always reaches the guide groove 124 through the first guide line 122. . The guide groove 124 fixes the adjusting pin 150 so that the slider 140 does not move even when the elastic force of the spring 160 is restored.

Figure 7b is an enlarged view of the main part of the main body for explaining the movement of the adjustment pin in the guide groove in one embodiment according to the present invention.

Referring to FIG. 7B, the protrusion 143 is pushed inward to discharge the inserted card 10. Accordingly, as the slider 140 moves inward, the adjustment pin 150 is out of the guide groove 124. The slider 140 is moved outwardly by the elastic force of the spring 160 which is restored when the adjusting pin 150 is disposed on the second guide line 123 after leaving the guide groove 124. The other end of the adjustment pin 150 moves from the second guide line 123 toward the start point on the first guide line 122. Since the second guide line 123 is formed higher than the first guide line 122, the first guide line is lowered without being blocked even in a place where the first guide line 122 and the second guide line 123 are in contact with each other. (122) Move on to reach the starting point.

When the adjusting pin 150 reaches the start point, the card is ejected and the position of the slider 140, the position of the adjusting pin 150, and the shape of the spring 160 are the same as the state in which the card 10 is not inserted as shown in FIG. It becomes a state.

When the card 10 is inserted into the card connector 100 according to the present invention, the terminal is malfunctioned due to a state in which the card is inadvertently ejected or not contacted, except that the card 10 may be pushed to the end. You can prevent it from happening. In addition, since the protrusion 143 pushes the card 10 out by the elastic force of the spring 160 to be restored during discharge, the card 10 may be conveniently taken out.
