Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector which is mounted on a printed circuit board for use and is fitted and connected to a mating connector such as an IC card, and more particularly to a connector having a mating connector releasing mechanism. .

[0002]

2. Description of the Related Art A connector of this type will be described with reference to FIG. The illustrated connector 10 is an insulator 2 having a pin contact 4 fixedly fitted and connected to a corresponding socket contact of a mating connector (not shown).
The insulator 2 is provided with a semicircular rotary shaft 15. An eject lever 13 for detaching the mating connector from the insulator 2 is rotatably held on the rotary shaft 15. Also,
As shown in the figure, the insulator 2 is formed with guide portions 21a and 21b for guiding the mating connector.

With reference to FIG. 6, such a connector 10
When connecting the mating connector to, the frame 6 is brought into contact with the connector 10. Guide portions 61a and 61b for guiding the mating connector are formed on the frame 6, and the frame 6 is provided with a detachment button 7 for rotating the eject lever 13. And
When the release button 7 is pressed, the eject lever 13 rotates about the rotation shaft 15 and the eject lever 1
The mating connector is detached from the insulator 2 by 3.

Referring again to FIG. 5, the connector 10 described above.
An automatic mounting machine is generally used to mount the device on a printed circuit board (not shown). The automatic mounter sucks the connector 10 and places it at a predetermined position on the printed board. In this way, since the connector 10 is sucked by the automatic mounting machine,
The insulator 2 is provided with a suction portion (suction surface) 21c, and at the time of mounting, the suction surface 21c sucks the connector 10 to dispose the connector 10 at a predetermined position on the printed circuit board.

[0005]

By the way, when mounting a connector on a printed circuit board by an automatic mounting machine,
The eject lever rotates due to centrifugal force, etc.,
The relative positional relationship between the insulator and the eject lever shifts, which makes mounting extremely troublesome. That is, there is a problem that the eject lever rotates during the automatic mounting.

In addition, since the eject lever rotates and rattles, the eject lever cannot be used as a suction surface. Therefore, as described above, the connector must be provided with a separate suction portion. As a result, there is a problem that the shape of the connector, that is, the insulator becomes complicated.

An object of the present invention is to provide a connector which does not rotate the eject lever during automatic mounting and has a simple shape.

[0008]

According to the present invention, an insulator, a contact provided on the insulator and coupled to a mating connector, and a rotatably mounted insulator on the insulator to connect the mating connector from the insulator. A connector is provided which has an eject lever to be disengaged, and a locking portion which locks the eject lever at a predetermined position is formed on the insulator. In this case, for example, the locking portion is a convex portion that applies a load to the rotation of the eject lever.

[0009]

In the present invention, since the locking portion for locking the eject lever to the insulator at the predetermined position is provided, when the connector is automatically mounted on the printed board by the automatic mounting machine, the rattling of the eject lever is performed. To prevent sticking
As a result, the eject lever can be used as a suction surface. Therefore, the relative positional relationship between the insulator and the eject lever does not shift, and mounting becomes extremely easy. Further, since the eject lever can be used as the suction surface, the shape of the insulator becomes simple.

[0010]

EXAMPLES The present invention will be described below with reference to examples.

Referring to FIG. 1, the connector 1 is provided with an insulator 2 and an eject lever 3, and a pin contact 4 is arranged in parallel with the insulator 2. The insulator 2 is formed of, for example, an insulating material such as synthetic resin, while the eject lever 3 is formed by punching a metal plate, for example. A conductive metal material is used for the pin contact 4.

The insulator 2 is substantially H-shaped, and has a pair of guide portions 21a and 21b for guiding a mating connector (not shown in FIG. 1), an abutment surface 22 with the mating connector, which will be described later. It has a coupling shaft 23 with the frame 6, a protrusion 24, a convex portion 25, and a rotating shaft 5.

The rotating shaft 5 is a surface 20 of the insulator 2.
And a pressing portion 5 provided on the side surface of the shaft main body 51 with a space between the shaft main body 51 and the one surface 20.
1a and. The rotary shaft 5 has, for example, a fan shape. That is, the shaft main body 51 has a fan-shaped planar shape, and the holding portion 51a also has a fan-shaped planar shape. And, the sector shape of the pressing portion 51a is
The fan shape of the shaft body 51 is integrated with each other to form one fan shape. Here, in the illustrated embodiment, for example,
The shaft body 51 has a sectoral shape with a cross section of about 150 °,
Further, the cross-sectional shape of the upper side including the pressing portion 51a of the rotary shaft 5 is a fan shape of about 240 °.

The eject lever 3 includes an end portion 31 and an end portion 3.
1, the push-out portion 32 of the mating connector 80 provided at the other end of the connector 1, the notch 33, and the rotation hole 3 formed substantially in the center
4, a step portion 35 formed adjacent to the rotation hole 34, and a convex portion 36 that defines the shape of the rotation hole 34. The rotation hole 34 has a fan shape whose shape is substantially the same as (similar to) the upper surface shape of the rotation shaft 5, and specifically, a fan shape of about 270 °. The rotary hole 34 is slightly larger than the fan-shaped portion of the rotary shaft 5, and therefore, the fan-shaped portion of the rotary shaft 5 can be passed therethrough. Further, due to the step portion 35, a step is formed between the front side and the rear side around the rotation hole 34 of the eject lever 3. That is, the circumference of the convex portion 36 is lowered by one step as the step portion 35.

Referring also to FIG. 2, when disposing the eject lever 3 on the insulator 2, the rotary shaft 5 is attached to the rotary hole 3.
Eject lever 3 combined at an angle passing 4
Is rotated in the direction indicated by the arrow 37, and the convex portion 36 of the eject lever 3 is inserted into the above-mentioned gap. As a result, the eject lever 3 does not come off from the rotary shaft 5. Then, when the eject lever 3 is further rotated in this state, the eject lever 3 moves to the insulator 2
After overcoming the upper protrusion 24, the protrusion 24 is locked and prevented from coming off.

Referring to FIGS. 1 to 3, when the eject lever 3 is rotated in the direction opposite to the arrow 37, the rotation is stopped when the protrusion 24 enters the notch 33. That is, the notch 33 and the protrusion 24 form the eject lever 3
Function as a detent. Thus, by inserting the rotary shaft 5 into the rotary hole 34, the eject lever 3
Is rotatably attached to the connector body 1 between the one surface and the holding portion 51a of the rotary shaft 5.

Install the eject lever 3 in a predetermined area,
That is, as shown in FIG. 2, the push-out portion 32 is rotated from the state in which the push-out portion 32 is locked to the insulator 2 to the state in which the notch 33 is locked by the protrusion 24 as shown in FIG. , The mating connector connected to the connector 1 can be detached. Then, when the eject lever 3 is positioned within the predetermined region in this manner, the peripheral portion of the rotary hole 34 and the holding portion 51 of the rotary shaft 5 are engaged with each other, and the peripheral portion of the rotary hole 5 is held by the holding portion 51a. Can be suppressed. As a result, the eject lever 3 from the rotary shaft 34
Is prevented from falling off.

Since the eject lever 3 rotates over the slope 26 and the convex portion 25 on the upper surface of the insulator, the riding on the slope 26 and the convex portion 25 becomes a load against the rotation of the eject lever 3, and the eject lever 3 rotates. It requires operating force to operate. As a result, the eject lever 3 is locked to the insulator 2 at a predetermined position.

The connection with the mating connector will be specifically described with reference to FIG.

A frame 6 is connected to the connector 1 by a coupling shaft 23 shown in FIG. The frame 6 is substantially H-shaped, and inside thereof, guide portions 61a and 61b of the mating connector 80 are formed, and outside thereof, a holder portion 62 for holding the button 7 is formed.

The mating connector 80 is guided by the guide portions 61a and 61b and is pushed in until it abuts on the abutment surface 22, and is inserted. As a result, the mating connector 8
0 socket contacts (not shown) are connected to the pin contacts 4 of the connector 1. At this time, the push-out portion 32 of the eject lever 3 is located deeper than the abutting surface 22.

On the other hand, when the mating connector 80 is taken out, the button 7 is pushed. Then, the eject lever 3
End portion 31 is pushed, and the eject lever 3 rotates about the rotation shaft 5. As a result, the pushing portion 32
As a result, the mating connector 80 is projected from the butting surface 22, and the connection between the mating connector 80 and the pin contact 4 is released.

When the connector 1 is automatically mounted on a printed circuit board, the eject lever 3 is provided with a slope 26 and a convex portion 2.
In the state of being locked to the insulator 2 by 5, it is adsorbed by the automatic mounting machine. At this time, the eject lever 3 is
An attempt is made to rotate on the insulator 2, but in order to rotate, it is necessary to get over the slope 26 and the convex portion 25, and an operating force for this is required. However, even if the upper surface of the eject lever 3 is sucked by an automatic mounting machine,
No external force is applied until the eject lever 3 moves over the slope 26 and the convex portion 25. As a result, the eject lever 13 does not rattle, and the eject lever 3 can be used as a suction surface. Therefore, the relative positional relationship between the eject lever 3 and the insulator 2 does not shift, and the mounting becomes extremely easy. Moreover, since the eject lever 3 can be used as the suction surface, the shape of the connector, that is, the insulator is simplified.

[0024]

As described above, according to the present invention, since the locking portion for locking the eject lever to the insulator at the predetermined position is provided, the connector is automatically mounted on the printed circuit board by the automatic mounting machine. At this time, rattling of the eject lever can be prevented, and as a result, the eject lever can be used as a suction surface. Therefore, the relative positional relationship between the insulator and the eject lever does not shift, and mounting becomes extremely easy. Further, since the eject lever can be used as the suction surface, there is an effect that the shape of the insulator becomes simple.

Further, since the rotation of the eject lever is restricted and the eject lever does not rattle, the eject lever does not rotate and hit other parts even when carrying a device incorporating the connector according to the present invention. It can also prevent rattling noise.
