Abstract

PURPOSE:To easily check the insertion status of a memory card by the lighting up of a display element by providing a memory card connector with a function for detecting the insertion status of the memory card. CONSTITUTION:A card guide 3 has a shape for holding the side faces of a mold body for a memory card 8 to suppress the play of the card 8 at the time of its insertion. In a completely fitted state between a memory card connector contact terminal 5 and a memory card contact terminal, the card 8 comes into contact with a memory card connector 1. In the completely fitted state between the terminal 5 and the memory card contact terminal, the mold end face of the card 8 is abutted upon the end face of a connector mold 2 having the terminal 5 on the connector 1. At the time, a card detecting switch 4 to be a memory card detecting function is turned on and a light emitting diode 6 set on the head of a card guide 3 for the connector 1 is turned on.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory card connector, and more particularly to a memory card connector having a function of detecting an inserted state of a memory card.

[0002]

2. Description of the Related Art A conventional memory card connector will be described with reference to FIG. The memory card connector 1 is composed of a connector mold 2, a card guide 3, and a memory card connector contact terminal 5. FIG. 4A is a perspective view of the memory card connector 1 and FIG.
It shows in (b). A method of engaging the memory card 8 with the memory card connector 1 is shown in FIG. The memory card 8 has a memory card contact terminal 9 fitted to the memory card connector contact terminal 5 on its end surface. When the memory card 8 is fitted to the memory card connector 1, it is inserted along the card guide 3 of the memory card connector 1. The state is shown in FIG. 5 (a), and the view seen from the upper surface in that state is shown in FIG. 5 (b). When the memory card 8 is completely inserted into the memory card connector 1, the memory card connector contact terminal 5 and the memory card contact terminal 9 are engaged with each other to be connected to each other.
FIG. 5 (d) shows a view of this from above in FIG. 5 (c). When removing the memory card 8 from the memory card connector 1, it is pulled out along the card guide 3. This state is shown in FIG. 5 (e), and a view from the top is shown in FIG. 5 (f).

[0003]

In the conventional memory card connector, when a memory card is inserted, it is necessary to visually check the mated state of the memory card connector contact terminal and the memory card contact terminal. It was difficult to confirm whether the memory card could be completely inserted into the memory card connector. In particular, the memory card connector is generally mounted inside the device, and it is not possible to visually check the mating state of the memory card and the memory card connector from the outside. I could not confirm the case where the memory card was pulled out from the memory card connector.

[0004]

According to the memory card connector of the present invention, when the memory card is inserted into the memory card connector, the card detection switch provided in the memory card connector is opened and closed by the insertion pressure of the memory card, and the main opening and closing is performed. The memory card insertion state element is turned on by the switch operation of or is sent as a control signal to the outside.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1A is a perspective view of a memory card connector according to an embodiment of the memory card connector of the present invention. FIG. 1B is a circuit diagram of the memory card detection function of the memory card connector. The memory card connector 1 includes a connector mold 2, a card guide 3 that serves as a guide when inserting a memory card, a memory card connector contact terminal 5 that engages with the memory card contact terminal 9 when the memory card 8 is inserted, and a memory card detection function. It comprises a card detection switch 4 constituting the above, a light emitting diode 6 which lights up when the memory card 8 is normally inserted, and a battery section 7 which supplies a current to the light emitting diode 6.
The memory card 8 inserted into the memory card connector 1 is composed of a memory card main body and a memory card contact terminal 9 adapted to the memory card connector contact terminal 5. Next, the operation of the memory card connector 1 of the present invention will be described with reference to FIGS. The card detection switch 4 of the memory card connector 1 is in a position facing the mold end surface of the memory card that protects the memory card contact terminal 9 when the memory card 8 is inserted, and the switch is normally open. It has become. A circuit diagram in this state is shown in FIG. The memory card 8 is inserted into the memory card connector 1 to connect them. The memory card 8 is inserted along the card guide 3 of the memory card connector 1. The card guide 3 is shaped so as to sandwich both side surfaces of the mold body of the memory card 8 and suppresses play between the memory card 8 and the backlash during insertion. FIG. 2A is a perspective view of the memory card 8 inserted into the memory card connector 1, and FIG. 2B is a top view thereof. The memory card 8 is connected to the memory card connector 1 with the memory card connector contact terminal 5 and the memory card contact terminal 9 engaged with each other. With the memory card connector contact terminal 5 and the memory card contact terminal 9 completely mated, the mold end surface of the memory card 8 contacts the end surface of the connector molding 2 having the memory card connector contact terminal 5 of the memory card connector 1. At this time, the card detection switch 4 is simultaneously pressed by the mold end surface of the memory card, the card detection switch 4 of the memory card detection function is turned on, and the light emitting diode 6 located at the tip of the card guide 3 of the memory card connector 1 is turned on. Will be done. A circuit diagram of the card detection switch 4 in a closed state is shown in FIG. Further, a perspective view of this state is shown in FIG. 2 (c), and a view seen from above is shown in FIG. 2 (d). When the memory card 8 is attached / detached from the memory card connector 1, the card detection switch 4 pressed by the mold end surface of the memory card 8 becomes the original switch open state as the memory card 8 is attached / detached,
The light emitting diode 6 will disappear. 3A and 3C are perspective views of this state, and FIG.
Shown in (b) and (d). In this way, the light emitting diode 6 lights up when the memory card 8 is completely engaged with the memory card connector 1 and both are connected, so that the insertion state of the memory card can be detected. Further, the battery unit 7 and the light emitting diode 6 which are a part of the detection circuit can be detached from the memory card connector 1 and externally attached. Alternatively, the switch opening / closing signal of the card detection switch 4 may be simply used as a control signal for inserting / removing the memory card 8 into / from the memory card connector 1 without using the battery unit 7 and the light emitting diode 6.

[0006]

As described above, the memory card connector of the present invention is provided with a function of detecting the insertion state of the memory card in the memory card connector, so that the insertion state of the memory card can be easily confirmed by lighting the display element. It is possible to prevent the connection failure between the memory card and the memory card connector.
