A conventional example is a mating connector (PC card)
Equipped with a U-shaped guide frame to guide the storage and discharge of
An ejection mechanism for removing the PC card is incorporated. The ejection mechanism (ejector) includes an ejection button (button), a discharge lever, and the like.

[0004] By the way, when the mating connector is ejected, a drop prevention mechanism is provided to prevent the mating connector from falling down and being damaged by excess force.

[0005]

However, in these conventional examples, since the fall prevention mechanism of the mating connector is urged by a spring or the like, the side surface of the mating connector is always pushed regardless of the position of the ejector. I have. For this reason, there is a disadvantage that the card insertion force is increased and the operability is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a connector with an ejection mechanism having a low card insertion force and an excellent operability and having a function of preventing a mating connector from falling.

[0007]

To solve the problems of the present invention, the following means are adopted.

A plate with an eject mechanism having a plate, a lever, and an eject mechanism having an eject button for detaching a rear end from the state, wherein the plate has a butting surface portion for detaching the mating connector. And left and right sliding ends extending from left and right ends of the plate body and engaging with the mating connector, respectively.
The plate body is slidably mounted along the insertion direction between the frame body and the vicinity thereof, and when the eject button is driven to operate the lever, the plate is moved together with the mating connector. As the abutting surface portion slides away from the rear end of the mating connector, the left and right sliding ends also slide and lock with the mating connector. A connector with an eject mechanism, wherein the connector is braked to apply a brake to prevent the mating connector from jumping out and falling.

(2) In the connector with an ejection mechanism according to (1), left and right brake grooves are formed in the left and right projecting guides, and each of the brake grooves extends along the insertion direction. And the left and right separation distances are the same, and the taper groove portions formed by bending from the parallel groove portions so that the left and right separation distances along the front become narrower, while the sliding end is bent from the plate body. A side portion, a leaf spring portion extending from the side portion, a dowel extending from the leaf spring portion and protruding so as to face a side end of the mating connector, and a lower front end of the leaf spring portion. A sliding horn portion that extends and slides along the brake groove, wherein the left and right sliding horn portions slide from the parallel groove portion to the tapered groove portion, and have a dowel spacing. Wherein the right and left dowels frictionally contact each other while elastically sandwiching the left and right ends of the mating connector, and act as a brake.

(3) The connector with an ejection mechanism according to (1), further comprising a cover that covers the guide frame, the lever, and the plate, and a back surface of the cover is provided on a side edge of an upper surface of the mating connector. A dowel protruding downward so as to face is formed, while the sliding end is a base extending from the plate body, a taper extending from the base and abutting on the dowel, and A tip portion extending from a tapered portion and stepping on an upper surface of the mating connector. After the eject button is operated and the mating connector is disengaged by the lever, the dowels on the back surface of the cover are moved in the right and left sliding directions. As a result of contacting and pressing down the tapered portion of the end, the leading ends of the left and right sliding ends step on the left and right edges of the upper surface of the mating connector. A connector with an eject mechanism, wherein a brake is applied within the guide frame.

[0011]

The left and right brake grooves formed in the left and right projecting guides of the U-shaped guide frame are composed of parallel grooves and tapered grooves. On the other hand, a leaf spring portion having a sliding horn portion that slides along the brake groove is formed at the sliding end.

When the left and right sliding horns slide from the parallel groove to the taper groove, the dowel interval changes from a constant to a small value. As a result, the left and right dowels are in frictional contact with each other while elastically sandwiching the left and right ends of the mating connector, so that the brake works.

In the present invention, immediately after disconnection of the mating connector,
After a while, the effectiveness of the brakes will gradually improve. That is, the plate is locked with the sliding ends at the left and right ends of the plate, and the discharge force of the mating connector is braked.

More specifically, the effectiveness of the brake depends on the positional relationship between the brake groove and the dowel at the sliding end. Therefore, immediately after the mating connector is disconnected, the brake has little effect, but it works little by little. As a result, in the present invention, the mating connector insertion (discharge) force is low, and the operability is improved.

[0015] Further, a cover for covering the guide frame, the lever, and the plate may be further provided.

In this case, a dowel projecting downward on the back surface of the cover so as to face the side edge of the upper surface of the mating connector presses the tapered portion and the root portion of the sliding end downward. At this time, the left and right edges of the upper surface of the mating connector are stepped into the guide frame at the distal ends of the left and right sliding ends. As a result, the brake works.

The dimensions of the dowel interval W1 and the dowel interval W2 with respect to the width W of the mating connector 2 are set as follows.

The dowel interval W1> the mating connector width W> the dowel interval W2 As a result, when the mating connector 2 is discharged, the dowels 77 sandwich the left and right ends of the mating connector 2,
The discharge momentum of the mating connector 2 is reduced to prevent the mating connector 2 from jumping out and falling.

The effectiveness of the brake depends on the positional relationship between the brake groove and the dowel at the sliding end. Therefore, immediately after detachment of the mating connector, the brake has no effect, so that the connector insertion (discharge) force can be reduced and the operability is good. This is because the brake works well only when the left and right ends of the mating connector 2 are sandwiched.

Referring to FIGS. 7 to 11, the connector with an ejection mechanism according to the second embodiment of the present invention further includes a cover 50 that covers guide frame 30, lever 60, and plate 70.

Therefore, the height h1 of the distal end portion 78c is at a height that does not make contact with the mating connector 2.

Referring to FIG. 10, the left and right sliding ends 78 of the plate 70 contact the left and right dowels 54 when the mating connector 2 is detached and ejected. Therefore, the left and right dowels 54 push down the left and right sliding ends 78. The height h2 of the distal end portion 78c moves to a height at which it contacts the mating connector 2. In this manner, the left and right edges of the upper surface of the mating connector 2 are pressed by the left and right sliding ends 78.

As described above, since the left and right sliding ends 78 step on the left and right side edges of the upper surface of the mating connector 2 in the guide frame 32, the brake is applied to prevent jumping out.

[0048]

According to the present invention, the right and left sliding ends of the plate for braking the discharge force of the mating connector are provided immediately after the mating connector is detached, so that the sliding ends are linked. The brake works only when pressing the mating connector. As a result, it is possible to obtain a connector with an ejection mechanism, which has a low card insertion force and a card removal force, and has an excellent operability and has a function of preventing a mating connector from dropping.
