Are formed in a U-shaped cross section, and the opening sides of the U-shaped cross section are arranged to face each other. The pair of frames 2a and 2b are provided with regulating plate portions 23a which are bridged between respective upper surfaces of the U-shaped section. These restricting plate portions 23a are provided near the insulator 1 so as to vertically sandwich the contact portion 10a of the contact 10 together with the pair of frames 2a and 2b, and oppose each other in the contact direction of the mating connector 80 in the contact direction. Is formed into a fitting opening for accurately contacting the contact portion 10a.

The detaching mechanism includes a lever 3 rotatably mounted on a support 21 provided on the upper surface of the insulator 1 and a longitudinally outer surface of one of the frames 2a for moving the mating connector 80 in the detaching direction. And an ejector 4 attached along. The ejector 4 is provided on one of the frames 2a so as to be able to advance and retreat in the contact / removal direction.
Can be moved in a direction to separate from the contact 10.

One end of the lever 3 has a mating connector 80
An extruding portion 31 is provided so as to face the opposing surface of the mating connector 80 when is in contact with the contact portion 10a. The pushing section 31 plays a role of pushing the mating connector 80 in the detaching direction by rotating the lever 3.

In this embodiment, the ejector 4 is
It has a long plate-shaped eject bar 4a, and a block 5 that is press-fitted into the distal end of the eject bar 4a in the detaching direction. A lock member 6 is rotatably attached to the block 5. As shown in FIG. 2, the lock member 6 moves the ejector 4 forward and backward (corresponding to the contact / removal direction).
, And is rotatably supported by the block 5 so as to be rotatable in a direction perpendicular to the forward and backward directions.

Referring to FIGS. 2, 3 and 4, block 5 comprises:
A base 51 protruding from the distal end surface 5a in the detaching direction, a rotating shaft 52 formed in the base 51, a groove 53 in the detaching direction, grooves 54, 55, 56 in the rotating direction, and a pair of steps 5
7, a guide portion 58 and a taper portion 59 for stabilizing the operation in the ejection direction and the rotation direction.

The lock 6 has a groove 61 for inserting the base 51 of the block 5, a rotary hole 62 having a long oval shape in the ejecting direction, a projection 63 entering the groove 53 of the block 5, and a guide for the block 5. It has a guide portion 64 that meshes with 58.

A spring 7 having a pair of cantilevers extending from a rectangular parallelepiped is press-fitted into the lock 6, and each of the ends of the pair of cantilevers is bent to form convex portions 71 and 72. Have been.

When the lock 5 into which the spring 7 is press-fitted and the block 5 are assembled, the lock 6 becomes rotatable around the rotation shaft 52.

Here, when the convex portion 71 is engaged with the groove 56, the lock falls down as shown in FIG.

The protruding portion 71 passes through the groove 55, and as shown in FIG.
When the groove 54 reaches the groove 54, the lock is triggered as shown in FIG. 5C.

When disconnecting the mating connector 80, see FIG.
7, an ejecting force 66 is applied to the tip of the lock 6 as shown in FIG. 7. At this time, there is a gap 65 between the block 5 and the lock 6 until the gap 65 disappears due to the ejecting force 66. , The lock 6 is pushed into the block 5 to be in the state of FIG. at the same time,
Since the protrusion 63 is pushed into the groove 53, the lock 6 cannot be rotated.

At this time, since the convex portion 72 of the spring 7 rides on the tapered portion 59 of the block 5, the spring 7
Can be deformed.

When the ejection force 66 is released after the mating connector 80 is detached, the lock 6 is pushed back by the restoring force of the deformed spring 7, and returns to the state shown in FIG.
The lock is rotatable.

When the ejection force 66 is applied, the lock 6
In order to prevent the wobble in the rotation direction, the protrusion 6
3 cannot be rotated unless it gets over a pair of steps 57. Referring to FIG. 5C, when a bending force P is applied to the lock 6, the bending P 'applied to the protrusion 63 by the moment Pb is reduced by increasing the distance a from the rotation center. , The projection 63 can withstand a large bending force P.

Further, the guide portion 64 of the lock 6 and the guide portion 58 of the block 5 are fitted to each other to prevent the vertical play of the arrow shown in FIG.

As described above, according to the present invention, a connector with an ejector in which the lock does not rotate at the time of ejection can be obtained.

[0033]

As is apparent from the above description, according to the present invention, when the ejecting force is applied to the lock, the lock and the block engage with each other, and the lock cannot rotate. The lock guide is prevented by the block guide and the lock guide, and the lock returns to a rotatable state when the ejection force is removed after the ejection.

Therefore, the present invention is convenient because the IC card or the memory card can be reliably ejected from the connector at the time of the ejection operation, and the lock can be immediately depressed after the ejection.
