Description

[Detailed Description of the Invention] [Summary] A card connector that is provided with a slider that releases the contact between the card and the contacts when removing the card housed in the insulating card accommodating portion, and does not require any removal force. Therefore, compared to the conventional method in which the contact portion is removed while in contact, removal is extremely easy and the life of the contact portion is extended.

[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.

Such card connectors are desired to have low contact force when inserting and removing the contacts from the card.

[Conventional technology]

In the conventional card connector, as shown in a cross-sectional view in FIG. 5, the contacts 3' are arranged so that one end of the insulator 1' is located in the card accommodating part 2' of the insulator 1', which has a card accommodating part 2' with one side open. It was installed,
When the card 4' is inserted through the opening, the card 4' lifts the tips of the contacts 3' upward, and the spring properties of the contacts 3' bring them into contact with the contact portions of the card 4'. In connectors for such cards, contact 3' is removed during insertion and removal.
The card 4' is in contact with the card 4', and since this contact force is a problem, a connector as shown in cross section in FIG. 6 was developed.

This is because the card accommodating part 2' and the contact setting part 11 are separate members, and the card accommodating part 2' and the contact setting part 11 are connected to the rotating shaft 12.
It is integrated so that it can be opened and closed in the rotational direction via the . Such a connector is first installed in the card accommodating section 2'.
The card 4' is inserted into the accommodating part 2' in an open state, 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]

The conventional card connector described above has no contact force when inserting and removing a card, but it requires more parts and is expensive, and also requires a large space to open and close the card accommodating section, resulting in a large size. .

The present invention aims to solve the above problems.

[Means for solving problems]

In order to solve the above problems, the present invention has a card accommodating part that is open on at least one side, and a contact is installed so that one end is located outside to be connected to a printed board etc., and the other end is located inside. When a card is accommodated in the card accommodating portion of the insulator, the card and the contact portions of the contacts come into contact with each other to establish an electrical connection, and the connector is located parallel to the card accommodated;
The slider is provided with a slider that presses the contact and releases the contact state between the contact and the card by sliding it when the card is removed, and the slider maintains its position when the card is housed in the insulator. A card connector is provided, characterized in that it has a protrusion that contacts the card and the upper wall of the insulator with pressure so as to hold the card.

[Effect]

According to the above means, when attempting to remove the card from the card storage state, by inserting a slider, the contacts in contact with the card are pushed upward, thereby releasing the contact between the card and the contacts, thereby causing friction when the card is removed. I run out of power.

〔Example〕

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

FIGS. 2a to 2c show cross-sectional views for explaining the first embodiment of the present invention.

In the figure, 1 is the insulator that is the main body of the connector,
2 is a card accommodating portion provided in the insulator 1, 3 is a contact, 4 is a card, and 5 is a slider.

First, the structure of each part will be explained.

The insulator 1 has a space inside thereof into which the slider 5 and the card 4 are inserted, and a plurality of holes 1a, 1b, 1c are formed on the top surface for fixing the slider 5 or for escape of the tips of the contacts 3. ing.

The contacts 3 are formed to have several bent parts including a contact part 3a with the card 4, and are fixed to the insulator 1 so as to be arranged in a plurality in a direction perpendicular to the plane of the drawing.

The card 4 has a contact portion 4 which is a stepped portion at a position corresponding to a plurality of contacts 3 fixed to the insulator 1.
It has a.

The slider 5 has protrusions 5a and 5b formed on its upper and lower surfaces, and is slidably fixed by gripping the upper surface of the insulator 1 with an arm 6 as shown in FIG.

FIG. 2a shows the state before the card 4 is inserted, and the slider 5 is also not inserted inward. From this state, the card 4 is inserted as shown in FIG. 2b. When inserting the card, the upper surface of the card 4 comes into contact with the projection 5b on the lower surface of the slider 5, pushing the slider 5 upward. As a result, the protrusion 5a on the upper surface is located in the hole 1c on the upper surface of the insulator 1, and the slider 5 is fixed to prevent undesired sliding movement (especially in the direction of arrow A), and the contact portion 3a of the contact 3 and the card 4 are brought into contact with each other. The contact state of the portion 4a is maintained.

When removing the card 4, the slider 5 is inserted inward by applying an external force as shown in FIG.
By pressing b, the contact portion 3a of the contact 3 is raised upwards to release the contact state with the contact portion 4a of the card 4. In this state, the protrusion 5a on the top surface of the slider 5 is located in the hole 1b on the top surface of the insulator 1, preventing it from sliding in the direction of arrow B. Further, the tip portion 3b of the contact 3 applies force to the slider 5 in the direction shown by arrow C.

As shown in FIG. 2c, remove the card 4 with the contact state released (not shown). When the card 4 is removed, the protrusion 5b of the slider 5 that was in contact with the top surface becomes non-contact, and the slider 5 moves downward. The protrusion 5a on the top surface is removed from the hole 1b of the insulator 1, and the slider 5 is attached to the tip 3 of the contact 3.
The force applied by b causes it to slide in the direction of arrow B, returning to the state shown in FIG. 2a.

Next, a second embodiment will be described with reference to cross-sectional views shown in FIGS. 3a to 3d.

The same parts as in Figure 2 are given the same symbols.

In this embodiment, at least one bent plate spring 7 is installed, one end of which is fixed to the insulator 1, and the other end is a free end located in a space inside the insulator 1, and has a stopper part 7a at its tip. Further, the slider 5 is provided with a stepped portion 5c corresponding to the stop portion 7a at the tip of the leaf spring 7.

FIG. 3a shows the state before the card 4 is inserted, and both the contacts 3 and the leaf spring 7 are partially located within the card accommodating part 2. From this state, as shown in FIG. 3b, insert the card 4 into the card storage section 2.
Insert into. The contact portion 4a of the card 4 contacts the contact portion 3a of the contact 3, and the card 4
The bent portion of the leaf spring 7 is lifted upward by the upper surface of the leaf spring 7, whereby the tip of the leaf spring 7 is lowered downward.

When attempting to remove the card 4 from this state, the slider 5 is inserted inward by applying an external force as shown in FIG. 3c. The tip of the slider 5 presses the tip 3b of the contact 3, lifts the contact portion 3a upward, and pushes the contact portion 4a of the card 4 upward.
Release contact with. The slider 5 that has slid inward engages the step portion 5c with the locking portion 7a at the tip of the leaf spring. At this time, the tip end 3b of the contact 3 is applying a force in the direction of pulling out the slider 5 (in the direction of arrow D), but the aforementioned engagement between the slider 5 and the leaf spring 7 prevents the slider from sliding in the direction of arrow D.

In this non-contact state, the card 4 is removed as shown in FIG. 3d. The bent portion of the leaf spring 7, which had been lifted by the upper surface of the card 4, falls downward, and the tip of the leaf spring 7 rises upward, causing the locking portion 7a to engage with the stepped portion 5c of the slider 5. It will be canceled. Then, the contact 3 applying force in the direction to pull out the slider 5 (in the direction of arrow D)
The slider 5 is pushed outward by the tip 3b and returns to its original state as shown in FIG. 3a.

In the embodiment explained in FIGS. 2 and 3, there is no contact force only when the card 4 is removed from the card accommodating portion 2 where the contact force is a problem, and the slider 5 is automatically moved at the same time as the card 4 is removed. It is now being pushed outward.

Next, a third embodiment will be explained with reference to sectional views shown in FIGS. 4a to 4c. The same numbers are given to the same parts in Figures 2 and 3.

In this embodiment, a second slider 8 that slides by a spring 9 is installed at the back of the card storage section 2, and the card 4 stored in the card storage section 2 is automatically pulled out by this second slider 8. .

FIG. 4a shows the state before the card 4 is inserted, and the second slider 8 is pushed to the right by the spring 9, lifts the contact 3 with its upper surface, and moves the contact portion 3a upward (in a position where it does not contact the card 4). ) is maintained. When the card 4 is inserted into the card accommodating portion 2 in this state, the leading end of the card 4 pushes the second slider 8, and the slider 8 is positioned in the substantially V-shaped bent portion of the contact 3. Then, the contact portion 3a of the contact 3, which is held in the upper position, that is, in a position where it does not come into contact with the card 4 and is exerting downward force due to its spring properties, falls downward and the card 4
The contact portion 4a is brought into contact with the contact portion 4a, resulting in a state as shown in FIG. 4b.

In this contact state, one inclined portion 3c of the approximately V-shaped bent portion of the contact 3 is connected to the second slider 8.
This is maintained because the second slider 8 comes into contact with the corner of the slider 8 and suppresses the movement of the second slider 8 from sliding to the right.

Then, in the above contact state, the slider 5 is inserted inward as shown in FIG. 4c. The tip of the slider 5 presses the tip of the contact 3, raises the contact portion 3a of the contact 3 upward, and
The contact state between the inclined portion 3c and the corner of the second slider 8 is released, the second slider 8 slides to the right by the force of the spring 9, and the card 4 is pushed outward from the card accommodating portion 2. The state returns to the original state shown in FIG. 4a.

In this embodiment, the contact portion of the contact 3 is raised upward both when the card 4 is inserted into the card accommodating portion 2 and when the card 4 is removed, and the operation is performed in a state where there is no contact force. I can do it. In addition, when the slider 5 is inserted from the inserted state of the card 4, the card 4 is automatically pushed out, making it unnecessary to take out the card.

Although the explanation was omitted in the second and third embodiments, the slider 5 is provided with protrusions 5a and 5a for preventing undesired sliding movements, as in the first embodiment.
5b is provided.

〔effect〕

According to the card connector of the present invention, it is possible to contact the card without increasing the number of work steps and without increasing the size of the card when removing the card, which has conventionally been difficult to do because it is difficult to apply force when there is a contact force. Since the force can be reduced to zero, the removal operation becomes easier, and the life of the contacts and cards is accordingly extended.

Further, since the slider is always kept in a stable state, the contact state between the card and the contacts will not be broken due to undesired movement of the slider.
