Description

[Detailed explanation of the invention] [Summary] A signal line and a power line are installed in a fixed holder, and a ground line is installed in a rotating holder into which a cassette is inserted.
The ground terminal provided on the cassette comes into contact with the ground wire when the cassette is inserted into the rotating holder, and the signal terminal and power terminal of the cassette are connected to the cassette connector to the signal line and power line, respectively, after the rotating holder is rotated. Since only the ground terminal of the cassette and the ground wire of the fixed holder are contacted when the cassette is inserted into the rotary holder, the ground terminal is connected more reliably first than the signal terminal and the power terminal.

[Industrial Application Field] The present invention relates to a cassette connector for connecting a cassette-shaped storage medium such as an IC card to the main body of a personal computer or the like.

In such a connector, it is necessary to connect the ground terminal before connecting the signal terminal and the power supply terminal to avoid problems such as damage to the storage medium, and it is desired that such connections be made reliably.

[Conventional technology]

A conventional cassette connector and a card used therefor are shown in FIGS. 4 and 5.

Conventionally, as shown in Figure 4, the ground contact 3'
Contacts 4' for signal terminals and power terminals are all attached to fixed holder 1' (in parallel in the direction perpendicular to the paper), and the shapes of the ground terminal, signal terminal, and power terminal provided on the card can be changed. This allows the ground terminal to be connected first.

That is, for example, as shown in FIG. 5, the ground terminal 10a is formed to be higher than the signal terminal and the power terminal 10b so that the ground terminal 10a comes into contact with the contact 3' first during the rotation stage of the rotary holder 2'. I was doing it.

[Problem that the invention attempts to solve]

With the conventional connectors mentioned above, the ground terminal can be connected to the signal terminal or to the signal terminal due to the difference in the height of the terminals provided on the card.
Because this is done slightly earlier than connecting the power terminals,
It was not possible to create a reliable time difference. Furthermore, it is extremely troublesome to form terminals of different heights in the manufacturing process.

The present invention aims to solve the above problems.

[Means for solving problems]

In order to solve the above problems, the present invention consists of a fixed holder that is electrically connected to the main body of a personal computer, etc., and a rotating holder that is integrated with a rotating shaft at the end of the fixed holder and into which a cassette is inserted. This is a cassette connector that connects by rotating the holder toward the fixed holder after inserting the cassette.The fixed holder is connected to the signal and power terminals provided on the cassette so that they come into contact with the signal and power terminals after the rotating holder is rotated. To provide a connector for a cassette in which a ground wire is provided so as to come into contact with a ground terminal provided on the cassette when the cassette is inserted into a rotary holder.

[Effect]

The ground terminal and ground wire can be connected when the card is inserted into the rotating holder, and the signal terminal, power terminal and signal line can be connected when the rotating holder is rotated.
Connection with the power line is made.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a connector which is an embodiment of the present invention, 1 is a fixed holder, 2 is a rotating holder, 3 is a contact for grounding, 4 is a contact for signal and power terminals, 5 is the IC card insertion part, 6 is the rotating shaft, 7 is the locking claw, and 8 is the IC
Window part that exposes the terminal of the card, 9 is an IC card,
10 is a terminal.

First, the structure will be explained.

The fixed holder 1 has a grounding contact 3 pulled out from the main body of a personal computer (not shown), and contacts 4 for signal terminals and power terminals introduced from the bottom surface, and one end of the fixed holder 1 has a rotary holder 2 that rotatably holds the rotary holder 2. It has a shaft 6 and has a lock pawl 7 at the other end that locks the rotary holder 2 when it is rotated.
The rotary shaft 6 holds a rotary holder 2 having a card insertion portion 5 with an open end for inserting an IC card 9 therein. This rotating holder 2 is normally held in an inclined state as shown in the figure by the action of a spring member (not shown) provided on the rotating shaft 6.

The contact 4 is led out from the bottom surface of the fixed holder 1 and exposed to the top surface, and is arranged at a portion of the terminals of the IC card 9 that correspond to terminals other than the ground terminal. The grounding contact 3 is introduced from the lower surface of the fixed holder 1 and is arranged at a portion of the terminal 10 of the IC card 9 inside the rotary holder 2 that corresponds to the grounding terminal.

Next, the operation of the connector of this embodiment will be explained.

First, an IC card 9 having terminals 10 such as a signal terminal, a power supply terminal, and a ground terminal arranged side by side in the connector configured as described above is inserted into the card insertion portion 5 of the rotary holder 2. At the time of this insertion, the ground terminal of the IC card 9 comes into contact with the ground contact 3 provided inside the rotary holder 2.

The rotary holder 2 into which the IC card 9 has been inserted is rotated toward the fixed holder 1 by applying force from its upper surface, and the lock claw 7 is engaged with the upper end of the movable holder 2, and the fixed holder 1 and the movable Keep the holder 2 in contact with each other. When the rotary holder 2 is rotated to this state, the terminals of the IC card 9 other than the ground terminal are brought into contact with the contacts 4 provided on the fixed holder 1, and an electrical connection is established.

FIG. 3 shows a sectional view for explaining another embodiment of the present invention.

Most of the features are the same as those of the first embodiment described above, but the feature is that the grounding contact is composed of two parts, a contact piece 3a and a pull-out piece 3b, which contact each other with pressure. The pull-out piece 3b has a spring property, and even if the movable holder 2 is repeatedly opened and closed, a certain amount of force is absorbed by the bending due to the spring property, and the damage of the contact is uniform. It is extremely small in comparison.

〔effect〕

A cassette connector like the one of this invention,
The ground terminal is connected when the cassette is inserted.
Since the signal terminal and the power supply terminal are connected by the subsequent rotational operation of the rotary holder, there is a sufficient time difference between these connections, and the ground terminal can be reliably connected first. Further, since all the plurality of terminals provided on the cassette need only be formed to have the same shape and height, the formation process becomes simple.
