DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC memory card connector.

[0002]

2. Description of the Related Art As is well known, IC memory cards are widely used for various purposes as external storage media indispensable for improving the portable function of small electronic devices. This IC memory card is connected to a circuit of an electronic device via an IC memory card connector connected to a connector built therein.

A conventional IC memory card connector is:
As shown in FIG. 6, an eject lever b is provided, for example, on the right side of the connector body a, and the contact of the connector of the IC memory card inserted from the insertion slot c is connected to the contact d of the connector body a. When ejecting from the connector body a, the eject lever b is pressed.

[0004]

In the above-mentioned conventional eject lever type connector, the eject lever b is connected to the connector main body a in accordance with the dominant hand and the mounting conditions for electronic equipment, for example, the upper side or the lower side of the printed circuit board. Since it is necessary to arrange on the right side or the left side, two types of connectors must be prepared, and since the eject lever b is provided on the side of the connector main body a, the mounting area on the wiring board becomes large, and the size is small. However, there is a disadvantage that it is not suitable for use in such electronic equipment, and further, the structure is complicated and the cost is high. SUMMARY OF THE INVENTION An object of the present invention is to provide an IC memory card connector that can solve such conventional inconveniences.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, an object of the present invention is to provide an insulated connector body having contacts mounted thereon, and an IC memory card for connecting a contact of an IC memory card connector to the contact. An eject member which is movable in the connection direction of the two contacts against the elastic force of the eject spring by being pressed by the eject member. A pair of lock spring plate pieces arranged in a row, and a concave portion having a width smaller than a length between tips of locking hook portions provided on the pair of lock spring plate members is formed in the connector body; The hook receiving portion of the lock receiving member embedded in the connector body projects so that the upper surface is flush with the surface of the connector body.
When the contact of the connector of the C memory card is connected to the contact of the connector main body, the pair of lock spring plate pieces are fitted into the recesses with the distance therebetween narrowed against the elasticity, and the locking hook portion is provided with the lock receiving portion. The IC memory card is locked by a hook receiving portion of the member, and when the IC memory card is further pressed, the IC memory card escapes from the concave portion to widen the interval.

[0006]

When the contact of the connector of the IC memory card is connected to the contact of the connector of the present invention, the eject member is pushed by the IC memory card and moves against the elastic force of the eject spring, and the pair of lock springs is moved. The locking hook of the plate piece is locked by the hook receiving portion of the lock receiving member provided in the concave portion of the connector body, and the eject member is held at that position. When the IC memory card is further pressed, the pair of lock spring plates escapes from the concave portion, and the gap is widened by the elastic force. Thus, the eject member returns to the original position by the elastic force of the eject spring, and the IC memory card is taken out by the eject member.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
1 and 2, reference numeral 1 denotes a connector body made of an insulating material, and reference numeral 2 denotes an ejecting member. The connector main body 1 includes contacts 3 arranged in two rows in a main body, and guide portions 4 and 4 having a U-shaped cross section parallel to the contacts 3 are integrally formed from one side of both ends of the main body. On the top of the part,
A recess 5 and a pair of lock receiving members 6 are provided.
The pair of lock receiving members 6, 6 are embedded so that the hook receiving portions 7, 7 protrude into the concave portion 5 and are flush with the surface of the main body portion.

The eject member 2 is made of, for example, a stainless steel plate, and both ends of the connector body 1 are bent in a U-shape.
The spring receiving pieces 8 ₁ , 8 ₂ cut inward from the main surface and both side surfaces of the main body and the guide portions 4, 4 are fitted into the guide portion 4 of the connector body 1. When pressed by an IC memory card (shown in FIG. 3) inserted between the four, it can slide along the connector main body 1. At the approximate center of the main surface portion, a pair of lock spring plate pieces 11, 11 having locking hooks 9 on the outside and arranged at intervals 10 are formed by punching.

Before the IC memory card is inserted, the ejection member 2 is located at the position shown in FIG. 1A by the ejection springs 12, 12, and the ejection springs 12, 12 are formed on the main body of the connector body 1. One end thereof is in contact with the spring receiving pieces 8 ₁ , 8 ₂ . The distance between the tips of the locking hooks 9, 9 of the lock spring plate piece 11 of the eject member 2 is wider than the width of the concave portion 5, and FIG.
As shown in (B), when the IC memory card 14 is inserted between the guide portions 4 and 4 of the connector main body 1 and the contacts of the connector of the IC memory card 14 and the contacts 3 of the connector main body 1 are connected, Card 14
The ejecting member 2 is moved by the pressure, and the pair of lock spring plate pieces 11, 11 are separated from each other by a distance of 10 against the elasticity.
The locking hooks 9 are locked in the hook receiving portions 7 of the lock receiving members 6. Thus, the IC memory card 14 is not ejected by the eject member 2.

When the IC memory card 14 is taken out of the connector, the IC memory card 14 is pushed further deeply, and as shown in FIG. Escape to the main body surface. Thus, the interval 10 between the pair of lock spring plate pieces 11, 11 is restored, and the eject member 2 returns to the position shown in FIG. 5 (same as the position shown in FIG. 1) by the action of the eject springs 12, 12. The IC memory card 14 is taken out.

In FIG. 1, reference numeral 15 denotes a grounding strip which contacts the conductive case of the IC memory card 14 and grounds the conductive case. The connector body 1 protrudes inward through a hole in the guide portion 4. Reference numeral 16 denotes a hold-down fitting, which has a U-shaped section fitted into the recess 13 and is attached to the connector body 1 as shown in FIG. Inward protrusion 1
7 and is in contact with the ejection member 2. 18 is a hold-down member, and 19 is a projection for positioning on a printed circuit board.

[0012]

According to the present invention, since the IC memory card connected to the connector can be taken out of the connector only by pushing the connector deeper, the present invention can be applied to a human hand or an electronic device. Being irrelevant, only one kind needs to be prepared, and because it is small, it can be used for small electronic equipment, and the structure is simpler and the cost is lower than the conventional eject type. It has the effect that can be done.
