[Detailed description of the invention]

[0001]

The present invention relates to a magazine case for accommodating a plurality of printed circuit board connectors. More specifically, the present invention relates to a magazine case for a connector housing device (hereinafter, referred to as a stocker) capable of automatically discharging a connector by a robot or the like.

[0002]

2. Description of the Related Art Next, the configuration of a conventional magazine case will be described with reference to FIG. FIG. 3A is a plan view of the magazine case, and FIG. 3A is a front view of FIG. 3A. 3 is a connector, 2 is a stopper, and 5 is a magazine case. FIG.
Is a connector for a printed circuit board, and includes a housing 1A and pins 1B. Magazine case 5
As shown in FIG. 3, the connector 1 is formed in a reverse convex shape and houses a plurality of connectors 1 so as to surround the housing 1A of the connector 1.

In FIG. 3, an end 5A of the magazine case 5
Since the stoppers 2 protrude into the magazine case 5 at four locations on the side surfaces 5C and 5D of the 5B, the connector 1 does not fall out even when the magazine case 5 is transported. When housing the connector 1 in the magazine case 5,
The stoppers 2 on both sides of the end 5A of the magazine case 5 are pulled out, and the connector 1 is inserted.

The inside dimension Wh of the magazine case 5 is slightly larger than the width Wm of the housing 1A. When the connector 1 is pushed from one direction, the gap C is formed so that the connector 1 can be smoothly moved in the magazine case 5 without being clogged.
Is set.

Next, the configuration when the magazine case 5 of FIG. 3 is used for a stocker will be described with reference to FIGS. FIG. 4 is a plan view of the stocker, and FIG. 5 is a sectional view taken along line XX of FIG. 4 is a stocker, 7 is a transport mechanism, and 8 is a post-process.

In FIG. 4, the magazine case 5 in which the connector 1 is accommodated is mounted in the groove 6A of the stocker 6. A cylinder 6B is disposed behind the magazine case 5, and pushes and ejects the connector 1 in the magazine case 5 when the piston rod of the cylinder 6B moves forward. Magazine case 5
A shutter 6C is disposed in front of the shutter case 6C, and the shutter 6C moves up and down to close or open the outlet of the magazine case 5. In the stocker 6 of FIG. 4, three magazine cases 5 can be mounted.

The transport mechanism 7 includes a slide rail 7A, a hand 7B, a cylinder 7C, and a suction pad 7D. The slide rail 7A is arranged at right angles to the magazine case 5, and the hand 7B moves on the slide rail 7A.
The hand 7B holds a cylinder 7C, and the cylinder 7C
A suction pad 7D is attached to the tip of the piston rod. When the piston rod of the cylinder 7C moves forward, the suction pad 7D comes into contact with the housing 1A of the connector 1, and the suction pad 7D sucks the connector 1.

The connector 1 sucked by the suction pad 7D is transported to a post-process 8. The post-process 8 is, for example, a device for press-fitting a connector into a printed circuit board. There is a “press-fit connector press-fitting device for printed circuit boards”.

Next, the operation of FIG. 4 will be described. In the apparatus of FIG. 4, when activated, the hand 7 </ b> B is commanded by an operation control unit (not shown) and moves to the front of the magazine case 5. Next, the piston rod of the cylinder 6B moves forward and the connector 1
Is pressed against the shutter 6 and stopped. FIG. 5 shows a state in which the connector 1 in the magazine case 5 is in contact with the shutter 6.

From the state shown in FIG. 5, the piston rod of the cylinder 7C moves forward, and the suction pad 7D is sucked to the connector 1. Next, the shutter 6C is lowered, the piston rod of the cylinder 7C is retracted, and the connector 1 is pulled out of the magazine case 5. Next, the hand 7B moves to the position of the post-process 8, and conveys the connector 1 to the post-process 8.

[0011]

In FIG. 4, when the post-process 8 is a connector press-fitting device or the like, the post-process 8 must be accurately conveyed to the post-process 8. It is possible to accurately position the magazine case 5 in the groove 6A of the stocker 6 to about 0.05 mm. However, as shown in FIG. 3, a gap C of about 0.1 mm is required for the connector 1 to move smoothly into the magazine case 5. Therefore, it was difficult to position the connector 1 with high accuracy in the post-process 8.

When the magazine case 5 is mounted in the groove 6A of the stocker 6, care must be taken not to spill the connector 1 from the magazine case 5 in order to remove the stopper 2 on the discharge side of the magazine case 5. there were.

According to this invention, a ball is provided at the discharge end of the magazine case, a part of the spherical surface is projected into the magazine case, and the ball is elastically held to prevent the connector from dropping and to discharge the connector. It is an object of the present invention to provide a magazine case that is pressed against the inner wall of the magazine case when performing.

[0014]

In order to achieve this object, in the present invention, a plurality of connectors 1 for a printed circuit board are housed, and a housing 1A of the connector 1 is wrapped at a movable interval, and is provided at a first end. In a magazine case having a detachable stopper 2, a spherical surface protrudes from an inner wall of the side surface 3C, which is held on a side surface 3C of a second end portion opposite to the first end portion,
A ball 4 for pressing the housing 1A in the width direction is provided on the inner wall of the side surface 3D opposite to the side surface 3C.

[0015]

Next, the construction of the magazine case according to the present invention will be described with reference to FIGS. FIG. 1A is a plan view of a magazine case according to the present invention, and FIG. 1A is a front view of FIG. 1A. 1 is a magazine case, 4 is a sphere, and the other is the same as FIG. That is, FIG. 1 shows a case where the ball 4 is added to the magazine case 5 of FIG.

In FIG. 1, the ball 4 is elastically held on the side surface 3C of the end 3B, and a part of the spherical surface of the ball 4 projects from the inner wall of the side surface 3. When the connector 1 is pushed from the end 3A side, the housing 1A is pressed by the ball 4 and is discharged while the housing 1A is in contact with the inner wall of the side surface 3D. When the magazine case 3 according to the present invention is mounted on the stocker 6 in FIG. 4, the stopper 2 attached to the side surface 3D of the end 3B in FIG. 1 is removed.

[0017]

Next, an embodiment of the present invention will be described with reference to an enlarged view of a main part of FIG. 2A is a case for holding the ball 4;
4B is a compression coil spring. In FIG. 2, case 4A
Is embedded in the side surface 3C of the magazine case 3. The spring 4B is held in the case 4A and presses the ball 4. The pressing force of the spring 4B is set so that the ball 4 is pressed by the maximum weight of the connector 1 in the magazine case 3 so that the ball 4 does not fall naturally, and is weaker than the thrust of the cylinder 6B in FIG. Further, the spring 4B may be an elastic material such as rubber. Ball 4
Is greater than the gap between the magazine case 5 and the housing 1A shown in FIG. 3.

[0018]

[Effect of the invention] In this invention, a ball is provided at the discharge end of the magazine case, and a part of the spherical surface is projected into the magazine case.
Since the ball is elastically held, the connector does not drop when the magazine case is mounted on the stocker, so that the mounting is easy. Further, since the connector is positioned on the inner wall from the magazine case, the connector can be transported to a subsequent process with high accuracy.
