Description

Connector for Card {CONNECTOR FOR CARD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card connector for connecting a card member in which a conductor portion such as a SIM (Subscriber Identity Module) card or a SD (Secure Digital) card is directed downward. Specifically, the card member is placed. The present invention relates to a card connector which can be miniaturized and reduced in size by forming at least a portion of the tray to be parallel with the flat portion of the card member.

In recent years, portable terminal devices such as mobile phones are equipped with a card connector to which a SIM card, an SD card, or the like is connected, and among them, a tray on which various cards are placed is provided so that the card can be easily moved in and out. A so-called tray-type card connector in which card is input and output together with the tray is often used.

The tray-type card connector has a configuration in which a tray formed as a separate component is added to the socket body provided in the card connector, which makes it difficult to lower the product height of the connector itself. For this reason, in order to solve this problem, Patent Document 1 below discloses a SIM card connector for the purpose of low magnification.

In the SIM card connector disclosed in the following Patent Document 1, the guide groove unit is formed by sliding a case formed by a connecting board electrically connected to the SIM card and a guide groove unit formed on both sides of the connecting board, and when mounting the SIM card. The tray is connected to the tray, and the tray is made of metal for improving strength, and has a bottom surface on which the SIM card is placed, and a side wall formed by bending an edge of the bottom surface to connect with the guide groove unit by sliding. By setting it as such a structure, according to the SIM card connector of following patent document 1, while the bottom face of the tray in which a SIM card is mounted is formed thinner than the conventional soft resin tray, it can become more resistant to external force.

[Patent Document 1] Japanese Patent Application Laid-Open No. 2011-519464

In the SIM card connector disclosed in Patent Document 1, the tray is made of metal. However, since the connector is a connector having a so-called reverse type tray in which the conductor portion of the SIM card is placed upward, the SIM card is made even if the tray is made of metal. The conductor section and the tray do not cause a short circuit.

On the other hand, in the case of a connector having a so-called normal type tray in which the conductor portion of the SIM card is placed downward, when the tray is made of metal, the conductive portion of the SIM card is supported by a part of the metal tray, so that the portion of the tray is supported. There is a danger of causing a short circuit by contacting the conductor portion of the SIM card. For this reason, the normal type tray is normally formed with the insulating resin material. However, when the tray is formed of a resin, it is necessary to form the resin to some extent in order to maintain a constant strength, and it becomes difficult to reduce or reduce the size of the tray, and consequently, to reduce the size and size of the connector itself. It becomes difficult to do it.

At this time, the insertion of the tray 29 is restricted by the drooping portion 28 formed inside the cover body 21 of the socket 11, and is arranged in the correct position. The support portions 35 and 36 formed in the tray 29 are inserted into the groove portions 17 formed in the housing 13 (see A in FIG. 7 and B in FIG. 7), and the card member 41 is provided in the housing. Since the card member 41 is pushed upward by the contact part 19 and the conductor part 42 of the contact 18 provided in 13, the card member 41 and a tray as shown in FIG. The clearance 43 is provided between the support parts 35 and 36 of (29).

By doing in this way, even if the normal type tray 29 is formed of a metal material, the short circuit with the card member 41 can be suppressed. In addition, since the tray 29 can be formed of a metal material, the thickness of the tray can be made thin, and as a result, the connector can be reduced in size. In addition, in the tray, at least a portion parallel to the flat portion of the card member, that is, in the first embodiment, the flat portion and the support portion are formed of a metal material, whereby the tray can be formed thin, and the connector can be reduced in size.

In addition, the card member 41 is deformed by contacting the contact portion 19 of the contact 18 so that an elastic force is generated, whereby the card member 41 and the support portions 35 and 36 of the tray 29 are formed. The gap can be made clearer.

Next, the removal of the card member 41 from the connector 10 will be described. When removing the card member 41 from the connector 10, first, as shown in FIG. 6C, the tray 29 inserted into the connector 10 is pulled out while the card member 41 is placed. Serve That is, the handle part 38 provided in the front side part 32 of the tray 29 is pulled out with a finger etc., and it is set as the state shown in B of FIG. Thereafter, the front of the card member 41 is held with a finger or the like, and the card member 41 is removed by pulling it out as it is (see FIG. 6A). At this time, since the cutting part 31 is provided in the front part 30 of the tray 29, the card member 41 is exposed and it is easy to pull out.

In the connector 10 of the first embodiment, the tray 29 has a structure that does not come off from the socket 11. That is, when trying to pull out the tray 29 from the socket 11, the 2nd latching part 25 formed in the cover body 21 of the socket 11 and the side part 32, 33 of the tray 29 were formed. By locking the first locking portion 34, the tray 29 does not come out of the socket 11. By doing in this way, the card member 41 can be mounted without a problem because the tray itself is stable even if a wall or the like for stably arranging the card member 41 is formed in front of the tray 29. In addition, since such a wall or the like is not formed on the tray 29, the tray 29 can be made small, and the connector 10 can be made smaller. In addition, the front of the tray 29 is opened, and the card member 41 can be easily pulled out from this open portion. In addition, the loss of the tray 29 can be suppressed.
