Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved electronic device storage container.

Semiconductor devices in general, especially dual, in, line (DI)
A tube carrier 1 having a cross section as shown in FIG. 1 is used to store L) type integrated circuits in a line, protect them, and transport them without damage.

The tube carrier 1 has a protrusion 2, an internal space 3, and a groove 4 so that the alignment state does not change even if the semiconductor device 5 is tilted arbitrarily within the tube carrier 1. A hole 7a*7b is provided in the part, and a stop pin 6 as shown in the perspective view of FIG.
Insert as shown.

That is, as shown in FIG. 2, the fixing pin 6 is composed of a nail-like head 8, a lower neck 9, a protrusion 10, and a tapered tip 11.

The length L of the straight section below the neck is slightly longer than the h dimension of the internal space 3 of the tube carrier 1, and the diameter of the projection 10 of the stop pin 6 is larger than the holes 7a, 7b of the tube carrier 1. The tube carrier 1 is also slightly enlarged to prevent the retaining pin 6 from being easily removed after being inserted into the tube carrier 1.

When the stop pin 6 is to be removed from the tube carrier 1, the holes 7a and 7b are deformed by pulling the head 8, and the stop pin 6 is pulled out from the tube carrier 1.

Note that this stop pin 6 is made of resin and is made by a resin molding method.

As described above, since the conventional tube carrier 1 holds the fixing pin according to the h dimension, tube carriers 1 with different h dimensions are required depending on the type of semiconductor device, and therefore, the tube carrier 1 is adapted to the h dimension. Plural types of retaining pins 6 are also required depending on the type of tube carrier 1.

For this reason, the cost of molds and the like for molding the tube carrier 1 and the stop pin 6 with resin was enormous, making it uneconomical.

Furthermore, in the case of using the conventional retaining pin 6, the head 8 of the retaining pin 6 always protrudes outside the tube carrier 1, so that the semiconductor device 5 is not attached to a plurality of tube carriers 1 stacked up during the manufacture of such semiconductor devices. When automatically storing or discharging the tube from the tube carrier 1, the head 8 of the locking pin 6 becomes an obstacle, and a special indexing device is required.

Moreover, since the tube carrier 1 is also used for lead processing, marking, testing, shipping, etc. in the semiconductor manufacturing process, the equipment for carrying out these processes becomes complicated.

The present invention was devised to eliminate the above-mentioned drawbacks of conventional storage containers for semiconductor devices, and allows electronic devices to escape from the outside into an insertion hole bored in a concave portion outside the storage container main body. A blocking stop pin is inserted through the head, and the stop pin is connected to a head that is locked within the concave portion of the storage container main body, and is connected to the head and is fitted into the insertion hole and locked. By comprising a locking part and a shaft part whose tip faces into the storage container body, the dimensions of the retaining pin for preventing electronic devices from escaping can be standardized regardless of the size of the storage container body. A storage container for electronic devices that is superior in terms of versatility and eliminates conventional problems such as the fixing pins not protruding from the storage container body and getting in the way during various tasks. It provides:

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIGS. 4 to 7. As shown in FIG. In the tube carrier 1, the hole 7a is not formed, and only the hole 7a is formed in the protrusion 2 as a hole for inserting a locking pin for preventing the electronic device from escaping, which will be described later.

FIG. 5 is a perspective view showing a locking pin 14 according to an embodiment of the present invention, and FIG. 6 is a sectional view of the tube carrier 12 with the locking pin 14 inserted.

In FIG. 5, the stop pin 14 has a head 15 larger than the hole 7a in FIG. The shaft portion 17 and the recessed portion 16
are connected by a tapered portion 18.

. This tapered part 18 functions as a locking part to prevent the above-mentioned retaining pin 14 for preventing the escape of the electronic device from being pulled out of the hole 7a, and even if the plate thickness T dimension of the tube carrier 12 is different, the tube It is designed so that it can be held in the carrier 12.

The distal end portion 19 has a tapered shape and is formed to be easily inserted into the hole 7a of the tube carrier 12.

Also, the height A of the head 15 is equal to the height A of the concave portion 1 of the tube carrier 12.
3 (depth H-h), and the retaining pin 14
With the tube carrier 1 inserted, as shown in Figure 6,
2, the head 15 of the stop pin 14 will not protrude.

Further, the length B of the retaining pin 14 under the neck depends on the type of thickness of the semiconductor device itself, so that it can be used in common even if the h dimension of the tube carrier 12 is different. The tube carrier 12 is designed to be smaller than the dimension (h-T) obtained by subtracting the plate thickness T of the tube carrier 12 from the h dimension corresponding to the small dimension.

Further, when removing the retaining pin 14 from the tube carrier 12, the head 15 may be pulled, or the pin 14 may be removed from the hole 7 as shown in FIG. 7, as in the conventional carrier tube 1 shown in FIG.
A hole 7a larger than the hole 7a may be formed opposite to the hole 7a, and the pin 14 may be removed by pressing the tip 19 of the pin 14 through the hole 7a.

According to the embodiment of the present invention, even if the stop pin 14 is inserted into the hole 7a provided in the protrusion 2 at one end of the tube carrier 12 as shown in FIG.
It does not exceed 2.

Therefore, since it is possible to stack the tube carriers 12 and push them out automatically, it is possible to automatically store the semiconductor devices 5 into the stacked tube carriers 12 in a tube loader or tube unloader of semiconductor device manufacturing equipment. It is easy to eject the semiconductor device 5 from the tube carrier 12, and therefore the manufacturing equipment for the semiconductor device becomes inexpensive.

Furthermore, even when the semiconductor device is stored in the tube carrier 12 and shipped, the retaining pin 1 is attached to the tube carrier 2.
4 does not protrude, so the shipping box etc. can be small, making it economical.

Moreover, the stop pin 14 of one embodiment of the present invention can be applied as is to a plurality of tube carriers 12 having different h dimensions.

That is, since the retaining pin 14 is held only by the hole 7a provided in the protrusion 2 of the tube carrier, it is completely unaffected by changes in the dimension h, so it is versatile, and the retaining pin 14 is Since only one type is required, it is economical to use only one type of mold for manufacturing the stop pin 14.

Furthermore, since the locking pin 14 and the tube carrier 12 can be freely combined, workability such as insertion of the locking pin 14 into the tube carrier 12 is improved.

In the above embodiment, the fixing pin 14 and the tube carrier 12 are connected by the tapered portion 18 of the fixing pin 14, but instead of this tapered portion 18, for example, a banana clip-shaped banana clip deformed in the diametrical direction may be used. , a rubber rod, or a metal rod with a groove provided on its circumferential surface, and a rubber O-ring provided in this groove.

The present invention is not limited to the above-mentioned embodiment, and for example, a groove may be provided around the head 15 of the locking pin 14 in order to make it easier to pull out the locking pin 14.

In addition, in the cross-sectional shape as shown in Fig. 8, the tube carrier 1
A slit 20 may be provided in the wall portion facing the hole 7a of No. 2.

Further, in the above embodiment, a storage container for storing dual in-line integrated circuits has been described, but this invention is applicable to general electronic devices such as single, in-line integrated circuits, transistors, and other similar shapes. It can also be applied to storage containers.

As explained above, this invention allows a locking pin for preventing electronic devices from escaping to be inserted from the outside into an insertion hole made in a concave portion outside the storage container main body, and this locking pin is a head that is locked within the recessed portion of the container body;
Since the locking part is continuous with the head and is fitted into the insertion hole and locked, and the shaft part whose tip faces into the storage container main body, it is possible to prevent electronic devices from escaping. The dimensions of the locking pin can be standardized regardless of the size of the storage container body, which is superior in terms of versatility, can be manufactured at low cost, and improves workability. It does not protrude from the storage container body to the outside, and has a moderately excellent effect in practical terms, such as being able to eliminate the conventional problem of being a hindrance during various operations.
