BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for mating a mating connector such as an IC card or a memory card, and more particularly to a compact and easy-to-operate device having a mechanism for detaching the mating connector. It is about connectors.

[0002]

2. Description of the Related Art An example of a conventional connector with a detachment mechanism is shown in FIG. The connector 41 includes an insulating frame body 43 to which a large number of conductive pin contacts 42 are fixed, and a lever 4 that rotates about a shaft 44 supported by the frame body 43 as a fulcrum.
5 and the ejector 46 provided on the frame body 43 so as to be able to move back and forth.
It has and.

The frame 43 is provided with a hollow portion 49 in which a socket-type mating connector 70 such as an IC card or a memory card is removably received in the direction of arrow 60. The mating connector 70 includes a corresponding contact (not shown) capable of contacting the contact 42 when fitted to the frame body 43.

One end of the ejector 46 is pivotally attached to one end of the lever 45 by a pin 47, and when the mating connector 70 is advanced, the lever 45 is attached to the shaft 44.
Is rotated about the center, and the extruded portion 48 on the other end side is projected into the hollow portion 49. When the push-out portion 48 projects into the hollow portion 49, the mating connector 70 fitted to the frame body 43 is pushed to separate it from the frame body 43.

[0005]

In order to reduce the force required for the detaching operation of the mating connector 70 in the above-mentioned conventional type connector 41, the distance A between the shaft 44 of the lever 45 and the pushing portion 48, It is necessary to set the relationship between the distance B between the shaft 44 and the pivot pin 47 so that A <B. For that purpose, it is necessary to arrange the shaft 44 as close to the inside of the frame body 43 as possible and to make the push-out portion 48 close to the shaft 44.

However, since the shaft 44 is composed of a pin that penetrates the frame body 43 in the thickness direction, it cannot be arranged on the path of the mating connector 70. Therefore, the shaft 44 is arranged at the outer position avoiding the path of the connector 70.

Further, the mating connector 70 has a corner cut off in an arc shape in consideration of the convenience of insertion into the frame body 43 and the convenience of handling. Therefore, the pushing portion 48 of the lever 45 is
Since it has to be in an inner position sufficient to contact the flat surface 71 at the tip of the mating connector 70, there is a limit to making the position of the pushing portion 48 close to the shaft 44 and making A small. On the other hand, in order to set B to a large value, the connector 41
Increasing the size of is inevitable.

For the above reasons, in the conventional connector 41, there is a limit in setting the ratio of A and B to a large value, and a relatively large force is required for the detaching operation of the mating connector 70.

Therefore, it is an object of the present invention to provide a connector with a detaching mechanism, which enables the detaching operation of the connector 70 with a small operating force.

[0010]

In order to solve the above problems, the present invention has a contact for connecting to a corresponding contact of a mating connector, and the corresponding contact makes contact with or separates from the contact. In order to move the corresponding contact to the contact at the extruded portion on the one end side, the frame is fitted with the mating connector and the shaft supported by the frame is rotated as a fulcrum so that the corresponding contact can be moved in the direction of movement. A lever for moving the mating connector in a direction to disengage the mating connector, and a lever provided on the frame so as to be movable back and forth, and the other end of the lever for rotating the lever to move the mating connector In a connector with an ejector that engages on the side,
The shaft is integrally formed with the lever, and has a recess at the center in the axial direction for avoiding contact with the mating connector in a fitted state with the frame. A connector with a disconnection mechanism was constructed.

[0011]

In the connector with detachment mechanism of the present invention, when the mating connector is fitted, the side portion of the mating connector is received in the recess in the center of the shaft to avoid this. Therefore, the shaft can be arranged inward of the frame body by the amount of the recess without changing the position of the pushing portion. If the shaft is arranged inward, the distance A between the shaft and the push-out portion of the lever is relatively reduced, and conversely, the distance B between the shaft and one end of the lever is reduced.
Can be expanded. Since the ratio of the distance A <the distance B becomes large, the moment of the force generated in the lever at the time of the separation operation becomes large, and the operation force is reduced. Since the shaft is integrated with the lever, the number of parts is reduced and the assembly is easy.

1 to 3, a connector 1 includes an electrically insulating frame body 2, a lever 3 pivotally attached to the frame body 2,
The frame 2 is provided with an ejector 4 that can be moved back and forth.

A large number of conductive pin contacts 5 are fixed to one end of the frame body 2. The frame 2 is provided with a hollow portion 6 into which a socket-type mating connector 70 such as an IC card or a memory card is removably fitted and removed in the direction of the arrow 60, and the other end side is opened to receive the mating connector 70. is doing. The mating connector 70 includes a corresponding contact (not shown) capable of contacting the contact 5 when fitted to the frame body 2. The frame 2 is shown in FIG.
As shown in FIG. 3, the guide frame 7 and the contact frame 8 are constituted, and the both are connected by the fitting engagement of the engaging projection 9 and the engaging recess 10.

The guide frame 7 has a mating connector 70.
A pair of parallel guide portions 11 and 12 for slidably receiving both side edges of and guiding the side edges are provided on both sides. On the outer side of the one guide portion 12, a rectangular tube-shaped holder portion 13 that holds the ejector 4 so as to be movable back and forth along the guide portion 12 is provided.

The contact frame 8 is substantially box-shaped, and a large number of pin contacts 5 are arranged on one end side in a direction orthogonal to the fitting direction of the connector. The contact frame 8 is provided inside with a space 14 capable of receiving the tip portion of the mating connector 70. This space 1
4 is open at the other end of the contact frame 8.

The lever 3 has a push-out portion 15 on one end side and an engaging portion 16 on the other end side, and rotates with respect to the contact frame 8 with an intermediate shaft 17 as a fulcrum. The shaft 17 includes the upper and lower plates 24 of the contact frame 8,
It is fitted in the bearing hole 18 formed in 24. About half of the bearing hole 18 hangs over the space 14.
As shown in FIGS. 1 and 9, the shaft 17 is integrally formed with the lever 3 and has a recess 19 at the center in the axial direction. The recess 19 is the mating connector 7 fitted to the frame body 2.
0 for avoiding contact with the side portion on the tip side, even if a part of the shaft 17 is inside the space 14,
4 does not prevent the mating connector 70 from entering the connector 4. When the lever 3 is in the position indicated by the chain double-dashed line in FIG. 3, the push-out portion 15 is located outside the space 14, but when it is in the rotational position indicated by the dotted line, the push-out portion 15 projects into the space 14 and is fitted therein. The mating connector 70 in the state is pushed out from the space 14. The ejector 4 extends along the guide portion 12 to the side portion of the contact frame 8, and its tip comes into contact with the engaging portion 16 of the lever 3. Ejector 4
Rotates the lever 3 counterclockwise in FIG. 3 when it is manually pushed in the mating direction of the mating connector 70,
The pushing portion 15 is projected into the space 14. Release your hand,
The ejector 4 is restored by the spring 20. A protrusion 22 is provided on the enlarged base portion 21 of the ejector 4. A guide hole 23 that slidably receives the protrusion 22 is formed in the holder portion 13 so as to extend in the fitting direction of the connector. The spring 20 is held in the holder portion 13 and constantly biases the ejector 4 in a direction to push the base portion 21 out of the holder portion 13.

Next, the operation of this embodiment will be described. First, the mating connector 70 is attached to the hollow portion 6 of the connector 1.
When the connector 70 is pushed into the guide part 11,
The corresponding contact (not shown) at the tip end thereof is guided by 12 and contacts the contact 5 of the connector 1 to obtain electrical conduction. In this state, when the ejector 4 is pushed in the inserting direction of the connector 70, the tip pushes the engaging portion 16 of the lever 3, the lever 3 rotates, and the pushing portion 15 pushes the tip portion of the connector 70 in the detaching direction. . Due to this disconnection, the contact 5 separates from the corresponding contact of the connector 70.

When the tip of the connector 70 enters the space 14 of the contact frame 8, the tip of the mating connector 70 abuts on the push-out portion 15 of the lever 3, so that the lever 3 is moved as shown in FIG. Place at the position indicated by the chain double-dashed line. At this time, the recess 19 of the lever 3 faces the space 14 side and receives the side portion of the mating connector 70 therein.
As long as the recess 19 receives the connector 70, the shaft 17
Can be arranged closer to the connector 70 side. As a result, the distance A between the shaft 17 and the pushing portion 15 is relatively reduced, and conversely, the distance B between the shaft 17 and the engaging portion 16 is enlarged. Since the ratio between the distance A and the distance B can be set large, the moment of the force generated in the lever 3 at the time of the detaching operation becomes large, and the operating force is reduced. The shaft 17 is mounted by press-fitting between the upper and lower plates 24, 24 of the contact frame 8 from the side and fitting in the bearing hole 18. Since the shaft 17 is integrated with the lever 3, the number of parts is reduced and the assembly is easy.

[0020]

As described above, in the present invention, since the shaft is integrally formed with the lever, the number of parts is reduced, the assembly is facilitated, and the manufacturing cost is reduced. In addition, since a recess is provided at the center of the shaft in the axial direction to avoid contact with the mating connector that is in a fitted state with the frame body, the fulcrum position of the lever is selected as the best position, This has the effect that the operating force when the connector is detached can be minimized.
