Description

[Detailed Description of the Invention] [Summary] A connector for a card, which includes a case that can accommodate a card in a removable manner, a contact provided in the case, and a connector for disconnecting the contact from the card. A pusher that can push up the card, a first slider that can hold the pushed up contact in that state, and a second slider that is biased by a spring in the direction of pushing out the card make it easy to remove the card. Makes it easy to remove.

[Industrial application field]

The present invention relates to a card connector for electrically connecting IC cards and the like, which have been widely used in recent years.

For such card connectors, a connector with zero insertion/extraction force is required from the viewpoint of longevity and operability. Also, due to mounting problems in equipment, if the card is mounted in such a way that the card does not protrude from the surface of the equipment when inserted into the connector, there will be no problem when inserting the card, but it may be difficult to grasp the card when removing it. Since this is not possible, countermeasures are required.

[Conventional technology]

In the conventional card connector, as shown in a cross-sectional view in FIG. 4, a case 1 has a card accommodating part 2 with one side open, and a contact 3 is installed so that one end thereof is located in the card accommodating part 2. , when the card 4 is inserted through the opening, the card 4 lifts the tip of the contact 3 upwards and removes the contact 3.
It is brought into contact with the contact portion of the card 4 due to its spring properties. In such a card connector, the contacts 3 and the card 4 are in contact with each other during insertion and removal, and this poses a problem in terms of operability and lifespan, so a connector as shown in a cross-sectional view in FIG. 5 was developed.

In this case, the card accommodating section 2 and the contact installation section 5 are separate members, and the card accommodating section 2 and the contact installation section 5 are integrated so that they can be freely opened and closed in the rotational direction via the rotating shaft 6. . In such a connector, the card 4 is first inserted into the card accommodating part 2 with the card accommodating part 2 open, and then the card 4 and the contacts 3 are brought into contact with each other by closing the card accommodating part 2. Note that a contact window is formed on the lower surface of the card accommodating portion 2 at a position corresponding to the contact portion of the card.

With this connector, there is no contact force at all when inserting or removing the card.

[Problem that the invention seeks to solve]

In the conventional card connector described above, if the connector is mounted so that the card does not protrude from the surface of the device, there is a problem in that there is no margin for gripping the card and it becomes impossible to remove the card.

The present invention was created in view of these points, and it is an object of the present invention to provide a card connector that allows a card to be inserted and removed even if the card is mounted so that it does not protrude from the surface of the device.

[Means for solving problems]

For this reason, in the present invention, as illustrated in FIG. pusher 12 that can be pushed up to break contact with
1 can be held in that state, and the state is released by the inserted card 17.
In a card connector consisting of a slider 13, by pushing the pusher 12,
At the same time as the first slider 13 moves to hold the pushed up contact 11, the second slider 15 pushes out the card 17 released from the contact 11, and the second slider 15 moves in the card pushing direction. It is characterized in that it is provided with a spring 16 that urges the.

[Effect]

By pushing pusher 12, card 1
7 and pushes up the contact 11 holding it, the second slider 15 can remove the card 17 from the case 10 by the repulsive force of the spring 16.

〔Example〕

1 to 3 are views showing embodiments of the present invention, in which FIG. 1 is a sectional view taken along the - line in FIG. 3, FIG. 2 is an exploded perspective view, and FIG. 3 is an assembled perspective view. .

As shown in FIG. 1a, FIG. 2, and FIG. 3, this embodiment includes a case 10, a contact 11, a pusher 12, a first slider 13, and a spring 14 that biases the slider. second slider 1
5, and a spring 16 that biases the slider.

A pusher 12 and first and second sliders 13 and 15 are slidably housed in the case 10, and the contacts 11 have bent portions at several locations, including a contact portion 11a with the card 17. It is fixed to the case 10 at one end.

By pushing one end surface 12a of the pusher 12, the other end 12b can push up the contact 11, which has a sloped surface. In FIG. 2, the tip 12b of the pusher 12 has a comb-teeth shape because the contacts 11 are provided in two rows.

The first slider 13 has a flat part 13a that supports the tip of the contact 11 so that the contact 11 pushed up by the pusher 12 can be held in that state. direction). Note that the flat surface portion 13a of this slider 13 that supports the contact 11 is shaped like a comb like the pusher 12. The second slider 15 has cards 1 on its left and right.
The card 1 has a guide portion 15a into which the card 1 is inserted.
When the card 7 is inserted, the card 17 slides inside the case 10 together with the card 17, and is normally biased by a spring 16 in a direction to push out the card 17.

The operation of this embodiment configured as described above will be explained with reference to FIG.

FIG. 1a shows the state before the card 17 is inserted,
Pushya 12 is also not pushed inward. When the card 17 is inserted from this state as shown in FIG. The slider 13 is pressed to move the slider 13 in the same direction. As a result, the tip of the contact 11 slides down from the flat part 13a of the first slider 13, and the contact part 11a comes into contact with the electrode part of the card 17. In this state, the engagement force between the concave portion of the electrode portion of the card 17 and the contact portion 11a of the contact overcomes the repulsive force of the spring 16, maintaining a lever state.

Next, when the pusher 12 is pushed to the left (in the direction of arrow C) as shown in FIG. As a result, the contact portion 11a of the contact 11 separates from the electrode portion of the card 17, and the card 17 is pushed out to the right (in the direction of arrow D) together with the second slider 15 by the repulsive force of the spring 16. At the same time, the second slider 15
The first slider 13 that had been pressed by the slider also returns to the right (in the direction of arrow E) and supports the tip of the contact 11. In addition, Pushya 12 is the next card 17
When the contact 11 is inserted, it is pushed back by the slope of the contact 11 and returns to its original state as shown in FIG. 1b.

As described above, according to this embodiment, the card can be automatically pulled out simply by pushing the pusher 12.

〔Effect of the invention〕

As described above, according to the present invention, the structure is extremely simple, and even if the connector is mounted so that the card does not protrude from the surface of the device, the card can be easily removed by pushing the pusher. It is extremely useful.
