[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector with a detaching mechanism, and more particularly, to a connector having a mechanism for detaching from a mating connector such as an IC card or a memory card used in a small electronic device or the like. Related to the improvement of. Hereinafter, in this specification, for convenience of description, the fitting side of each component is referred to as “front” and the disengagement side is referred to as “rear”.

2. Description of the Related Art FIGS.
The one described in Japanese Utility Model Publication No. 2-41378 is known. This connector is a flat plate-shaped plate 5 on which a mating connector 8 (a card in the case shown) as shown in FIG.
And an insulator 2 having contacts 1 arranged in rows at the ends. A lever 7 is supported in the center of a pillar provided inside the frame 3,
One end of the lever 7 is rotatably connected to the plate 5 and the other end is rotatably connected to the ejector 6 inserted into one side of the frame 3.

FIG. 4 shows a state in which such a connector is fitted with the mating connector 8, and in this state, the ejector 6 slightly projects from the frame 3. When the ejector 6 is pushed forward in this state, the plate 5 is moved backward as shown in FIG. 5 by the rotation of the support rod of the lever 7 connected thereto, and the mating connector is detached.

[0004]

In the case of the conventional structure as described above, the mating connector 8 is located substantially in the same plane as the contact 1 on the insulator 2 both in the fitted state and immediately after the uncoupled state. Become. Although the ejector 6 is engaged and disengaged, the ejector 6 may not be engaged and disengaged smoothly depending on the arrangement of the connector in the device and the usage condition of the device.

Therefore, an object of the present invention is to smoothly engage and disengage a mating connector from an obliquely upper side of the connector, that is, a connector with a detachment mechanism which has improved operability in fitting and detaching the connector with a detachment mechanism. To provide.

[0006]

According to the present invention, there is provided a connector having a disengagement mechanism for disengaging a mating connector, one end of which is rotatably connected to a fulcrum of a front end of the frame. A cover and a plate housed in the frame are included, and the cover has an engaging portion that rotates about the fulcrum as the cover opens and closes. Engagement-engaged parts and claws for engaging and disengaging the mating connector are formed at the front and rear ends, and the mating connector is guided upward at the rear end of the frame at the time of disengagement. A connector with a detachment mechanism is obtained, which is characterized in that a guide is formed.

[0007]

1 and 2 show a connector according to an embodiment of the present invention, in which parts having substantially the same functions as those of the conventional connector shown in FIGS. 4 to 6 are designated by the same reference numerals. Attach and display. The connector shown in FIG. 1 has a frame 3 having contacts 1 arranged in a row on the inner surface of the front end, a cover 4 openably and closably connected to the frame 3 via a fulcrum, and a mating connector 8 mounted thereon. And a plate 5 accommodated in the frame 3.

The frame 3 is provided with fulcrums 31 for supporting the cover 4 on both sides of the front end thereof. Frame 3
A pair of left and right slant guides 32 is formed at the rear end portion for guiding the mating connector upward when detached.

The cover 4 has a frame 3 at its front end.
Is rotatably connected to the fulcrum 31, and an engaging piece 41 (engaging portion) as shown in FIG. 3 is integrally formed near the fulcrum. As is apparent from the figure, the engagement piece 41 is arranged so as to rotate around the fulcrum 1 when the cover 4 is opened and closed.

The plate 5 has a flat plate-like structure and has a front end portion with a disengagement claw 51 which engages with a mating connector at the time of disengagement, and an engagement piece 41 which engages with both sides of the front end portion. A concave portion 53 (engaged portion) and a fitting claw 52 that engages with the mating connector at the time of fitting are formed at the rear end portion. Further, a notch 54 is formed in the center of the rear end portion of the plate 5 so that the backward movement of the plate 5 at the time of separation does not interfere with the guide 32 of the frame 3.

Next, the operation will be described. 1 and 3 (A) show a state at the time of fitting, and the cover 4 is closed. As is clear from FIG. 3A, the engagement piece 41 of the cover 4 is engaged with the engagement recess 53 of the plate 5 in front of the fulcrum 31. The cover 4 as shown in FIG.
When opened, the engaging piece 41 rotates around the fulcrum 31 as shown in FIG. The plate 5 that engages with the engagement piece 41 via the engagement recess 53 moves rearward as the engagement piece 41 rotates. That is, the engaging recess 53 moves rearward and approaches the fulcrum 31. Along with this, the mating connector placed on the plate 5 also moves rearward, and eventually is guided by the guide 32 of the frame 3 to move upward and separate from the connector of FIGS. 1 and 2. When the cover 4 is closed from this state as shown in FIG. 1, the engagement piece 41 rotates around the fulcrum 31 as shown in FIG. 3 (A), and the plate 5 is moved forward through the engagement recess 53. To move. Along with this, the mating connector placed on the plate 5 is also pushed by the claws 52 and moves forward to be fitted and connected to the contact 1.

[0012]

As described above, according to the present invention,
Insertion of the mating connector before fitting and removal after mating can be performed from the diagonally upper side of the connector (device), so that operability is improved. Further, the fitting and the disengagement can be performed only by opening and closing the cover, so that workability is significantly improved.
