A stopper pin is inserted into the hole 103 formed in the hole and the hole 104 formed in the lower wall to stop the electronic component 101 housed in the magazine 102. The electronic parts 101 are transported in this state, and the mounting of the electronic parts 101 by the automatic machine is performed by the magazine 102.
Supplied from Therefore, 10 electronic parts are attached to the stopper pin.
It is required that the 1 can be reliably stopped, can be attached and detached without a special tool, be safe and inexpensive, and that the magazine 102 can be repeatedly used.

As stoppers for stopping the electronic components housed in the magazine, there are a pin type made of synthetic resin and a plug-in type made of rubber.

As the pin type, as shown in Fig. 5, the head
A shaft 106 is provided on the shaft 105 in a projecting manner, and the tip of the shaft 106 is formed into a ball 107 (stopper pin A). As shown in FIGS. 6 and 7, the shaft 106 is located directly below the head 105. A ball 108 having a diameter larger than that of the portion 106, and a parallel surface 109 having the same diameter as the shaft portion 106 provided on the ball 108 portion (stopper pin B), a shaft immediately below the head 105 as shown in FIG. The part 106 is provided with a ball 110 having a diameter larger than that of the shaft 106 (stopper pin C). As shown in FIGS. 9, 10 and 11, the tip of the shaft 106 has a diameter larger than that of the shaft 106. The elliptical engagement part 111 is formed, and the engagement part 111 has an elliptical surface.
There is one provided with 112 (stopper pin D).

As for the stopper pin A in FIG. 5, the sphere 107 is rigidly formed on the shaft portion 106 of the pin, so that the cylindrical magazine 102 is provided.
Insertion into and removal from holes 103 and 104 is large and manual work is difficult.

Further, the insertion and removal of the stopper pin A into and from the holes 103 and 104 of the cylindrical magazine 102 are performed by the two holes 103 and 104 provided in the upper and lower wall members of the magazine 102, which makes the work of inserting the stopper pin more difficult.

Further, the stopper pin A is attached to the hole 103 / of the cylindrical magazine 102.
When inserting into and removing from the magazine 104, burrs (lower burrs: 113) are formed on the plate wall material with which the electronic parts of the magazine 102 slide, and the electronic parts are caught in the burrs (113), so that the electronic parts cannot be taken in and out satisfactorily.

Furthermore, the stopper pin A is attached to the hole 1 of the cylindrical magazine 102.
Holes 103 and 104 in magazine 102 when inserting into and removing from 03.104
Spread, and the magazine 102 cannot be used repeatedly.

For the stopper pin B in FIGS. 6 and 7 and the stopper pin C in FIG. 8, a large diameter ball 1 formed on the shaft portion 1
Since 08 and 110 are rigidly formed on the shaft portion 106 of the pin, the load for inserting and withdrawing into and from the holes 103 and 104 of the cylindrical magazine 102 is large and manual work is difficult.

In addition, stopper pin B, C hole 103 of cylindrical magazine 102
When inserting into and removing from the magazine 104, the holes 103 and 104 of the magazine 102 become wider, and the magazine 102 cannot be used repeatedly.

Further, since the large-diameter spheres 108 and 110 formed on the shaft portion 106 do not come into contact with the holes 103 and 104 formed in the magazine 102, there is vertical movement, and if the pin unnecessarily projects to the top, the magazine 10
When 2 is set in an automatic machine and electronic parts are mounted in the automatic machine, setting of the magazine 102 in the automatic machine is hindered.

The stopper pin D shown in FIG. 9 has a large-diameter elliptical engaging portion 111 provided at the tip of both holes formed in the upper and lower wall members of the magazine 102.
Holes in the magazine 102 to insert 103/104
When inserting / removing the stopper pin D into / from 104, magazine 1
A burr (burr: 113) is formed on the plate wall material with which the electronic component 02 slides, and the electronic component is caught by the burr (113), so that the electronic component cannot be taken in and out satisfactorily.

The stopper pins D are inserted into and removed from the holes 103 and 104 of the cylindrical magazine 102 on the upper and lower wall members of the magazine 102.
This is done with two holes 103 and 104, which makes the insertion work more difficult.

Further, since the stopper pin D has an oval engaging portion 111 formed on the outer side through both holes 103 and 104 provided in the upper and lower wall members of the magazine 102, the stopper pin D becomes unnecessarily long. , Its handling becomes inconvenient.

The plug-in type is a rubber plug as shown in Fig. 12.
When the inside of the cross section of the magazine 102 is plugged with 114, there is a risk that the electronic component 101 will fall out due to the plug 114 falling off, and also because the magazine is largely deformed because the plug 114 is pushed in, it cannot be applied to the automatic machine. There is.

"Means for Solving the Problems" The present invention provides a head for stopping electronic components by inserting them into holes formed in upper and lower wall members of a cylindrical magazine having a space for aligning and storing electronic components. A stopper pin for a magazine for electronic parts with a protruding shaft portion, which is made of synthetic resin, has an ellipse of a diameter larger than that of the shaft portion directly below the head, and abutting the upper and lower inner walls of the cylindrical magazine. It is a stopper pin for an electronic component magazine, which is provided with an engaging portion having a shape and a through hole is formed in the engaging portion.

[Example] As shown in Figs. 1, 2, and 3, the stopper pin is made of a synthetic resin such as polystyrene or nylon.
A shaft portion 2 is provided so as to project from the head portion 1, and an oval engagement portion 3 having a larger diameter than the shaft portion 2 is provided immediately below the head portion 1 of the shaft portion 2.
Is formed to have a smaller thickness than the shaft portion 2, and the engaging portion 3 is provided with a through hole 4. The holes may be circular holes or square holes, but oval holes are most preferable.

When this stopper pin is inserted into the hole 6 in the upper wall of the magazine 5, it enters the hole 6 from the tip of the shaft portion 2 and the engaging portion 3 has flexibility because it has the vent hole 4 and is easily deformed. After passing through the hole 6, the engaging portion 3 is restored and the tip of the shaft portion 2 is the hole 7 in the lower wall.
Located inside.

Since the engaging portion 3 is formed immediately below the head portion 1, it passes only through the hole 6 in the upper wall and does not pass through the hole 7 in the lower wall.

Further, the engagement portion 3 is set to have a length that contacts the upper and lower inner walls of the magazine 5.

[Advantage of the Invention] According to the present invention, a shaft portion is projectingly provided on a head for stopping electronic components by inserting the holes into upper and lower wall members of a cylindrical magazine having a space for aligning and storing electronic components. A stopper pin for a magazine for electronic parts, which is made of a synthetic resin and has an elliptical engagement with a shaft portion directly below the head, having a diameter larger than that of the shaft portion and abutting against the upper and lower inner walls of the cylindrical magazine. And a hole is provided in the engaging portion.

According to the present invention, the stopper pin is made of synthetic resin, and the shaft portion is provided with the elliptical engaging portion and the engaging portion is provided with the through hole. Therefore, the stopper pin is provided in the upper and lower wall members of the magazine. When inserting into and removing from, the load of insertion and withdrawal becomes small, and the stopper pin can be inserted manually.

Further, in the present invention, the stopper pin is inserted into and removed from the holes provided in the upper and lower wall members of the magazine only by the hole provided in the upper wall member of the magazine, and the stopper pin is inserted into and removed from the hole provided in the magazine. Work becomes easier.

Further, according to the present invention, when the stopper pin is inserted into and removed from the holes provided in the upper and lower wall members of the magazine, a burr is formed in the hole of the upper wall member of the magazine, but the lower wall member with which the electronic parts are slidably contacted is formed. No burr is formed in the provided hole, and the electronic component can be taken in and out satisfactorily.

Still further, according to the present invention, since the stopper pin engaging portion abuts the upper and lower inner walls of the cylindrical magazine, the stopper pin is firmly fixed to the magazine to prevent looseness, and as a result, the pin is unnecessarily placed on the upper portion. When the protruding magazine is set in the automatic machine and the electronic parts are mounted in the automatic machine, there is no problem in setting the magazine in the automatic machine.

Furthermore, according to the present invention, since the engaging portion of the stopper pin is located in the internal space of the magazine, the length of the stopper pin can be shortened, and as a result, the stopper pin can be easily handled.
