Description

[Detailed Description of the Invention] The present invention relates to a storage body in which so-called taped electronic components, in which a plurality of electronic components such as capacitors and resistors are attached to a tape body, are housed in a case body.

Taped electronic components have been widely used in recent years because they can be continuously supplied to printed circuit boards and the like by incorporating them into automatic insertion machines and the like.

Conventionally, a storage body as shown in the first figure has been devised as a storage body for incorporating this taped electronic component into an automatic machine or the like.

In the figure, 1 is a case, 2 is a shaft core fixed to the center of the inner bottom surface of the case 1, 3 is a winding core rotatably fitted to this shaft core 2, and the outer periphery of this winding core 3 is A taped electronic component 4 is spirally wound and housed in a case 1.

5 is a drawer opening opened so that the taped electronic component 4 can be pulled out from the case 1.

In other words, in this conventional device, when the taped electronic component 4 is pulled out from the drawer opening 5, the winding core 3 rotates about the shaft core 2 as a fulcrum, thereby facilitating the pulling out.

However, in this conventional type, since the thickness of the shaft core 2 is relatively thin, even a slight distortion of the case 1 can cause the mating with the winding core 3 to come undone, making it difficult to smoothly pull out the taped electronic component 4. There was a fear that it would disappear.

However, if the shaft core 2 and the winding core 3 become uncoupled and the electronic component cannot be pulled out smoothly, the electronic component 4 will become tightly wound due to the tensile force that is still applied, and its shape may become deformed. There was a fear that not only would automatic insertion be hindered, but that the taped electronic component 4 would eventually be separated.

In addition, since the above-mentioned conventional device has a structure in which the winding core 3 is fitted to the shaft core 2 fixed to the inner bottom surface of the case 1 as described above, the shaft core 2 is fixed to the inner bottom surface of the case 1 extremely firmly. If this is not done, the tensile force applied when the taped electronic component 4 is pulled out of the case 1 will cause the shaft core 2 to separate from the inner bottom surface of the case 1, making it impossible to pull out the taped electronic component.

Therefore, extremely complicated fixing means must be used, and when the case 1 is made of paper or the like, there is a problem in that it is extremely difficult to firmly fix the shaft core 2.

The present invention has been developed in view of these points, and it is an object of the present invention to provide a taped electronic component storage body that allows taped electronic components to be drawn out of the case body smoothly at all times and is extremely easy to assemble. The main feature is that the winding core is rotatably attached to the case body by using a through hole provided in the case wall.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Figure 2 is an external perspective view of the taped electronic component storage body;
The figure is an exploded perspective view of the same, and all are shown with the electronic parts removed for convenience.

In these figures, 11j2 is a main wall made of a thick paper material such as corrugated cardboard, and 13. Reference numerals 14j5j6 are side walls formed by bending the ends of appropriate main walls, which connect the bidirectional walls 11 and 12 to form a case body.

Reference numerals 17 and 18 refer to through holes provided in substantially central portions of the main walls 11 and 12 to face each other, and 19 refer to a winding made of a cylindrical body with both ends open and having an outer diameter larger than that of these through holes. It is a core and is provided inside the case body in communication with the through holes 17 and 18.

This winding core 19 is made of hard paper material, and its inner diameter is the through hole 1.
It is preferable to substantially match the diameters of Nos. 7 and 18.

Reference numerals 20 and 21 denote rotating shafts made of a suitable metal such as aluminum, brass, copper, or resin, having a diameter somewhat smaller than that of the through holes 17 and 18, and are inserted into the through holes 17 and 18, respectively. At the same time, one end thereof is inserted into the hole of the winding core 19 and fixed.

In other words, these co-rotating shafts 20 and 21 are inserted into the through holes 17 and 18, so that the winding core 19 is rotatably attached to the case body. In this case, a plurality of claws, protrusions, etc. are formed on the circumferential surface of the shaft, and the inner circumferential surface of the hole in the winding core 19 is spread out and press-fitted, or the diameter of the shaft is approximately the same as the hole in the winding core 19. It is possible to make the diameter the same and press fit, to form a recess on one side of the shaft peripheral surface and the inner peripheral surface of the hole in the winding core 19 and a convex part on the other, and to fit them together using the concave and convex parts, or to use an adhesive. Measures such as gluing are taken.

22 and 23 are flat bulges provided at the other end of the rotating shaft 20.21, which prevent the winding core 19 attached to the case body by the rotating shaft 20.21 from falling off from the case body. It is for.

Usually, between the inner surfaces of the main walls 11, 12 and the side surfaces of the winding core 19, and between the outer surfaces of the main walls 11, 12 and the bulges 22, 2 of the rotating shaft.
A slight gap is provided between the inner surface of the rotating shaft 20.3 and the rotating shaft 20.3 to ensure smooth rotation of the winding core 19.
Since the diameter of 21 is smaller than the through holes 17 and 18, the winding core 19
Although it is not so preferable that the bulge may rotate slightly eccentrically, it is possible to provide at least three circular protrusions equally spaced on the inner surface of the bulged portion 22, 23.
This can be prevented and the rotation of the winding core 19 can be made even smoother.

The bulging portions 22 and 23 may be formed by any means, such as being formed integrally with the shaft portion or by bending one end of the shaft portion into a petal shape.

Furthermore, if the shaft portions in contact with the bulging portions 22 and 23 are formed to have a concave cross section as shown in FIG. The recess of the rotating shaft 20.21 is the main wall 11.1.
2, and its rotation becomes reliable, making it easier to pull out the electronic components.

Reference numeral 24 denotes a draw-out port for drawing out the taped electronic component to the outside of the case body, and is formed by making a perforation at one end of the side wall body 16 to make it bendable.

Although not shown in FIG. 3, the inner peripheral surfaces of the through holes 17 and 18 are provided with a covering 25 made of a slippery material such as metal or vinyl, as shown in FIG. There is.

In the taped electronic component storage body of the present invention, the taped electronic component 4 as shown in FIG. It consists of being wound around.

The taped electronic component is usually wound around the core before the core is attached to the case body, but it can also be done after the core is attached to the case body.

The taping electronic component storage body configured as above is
When installed in an automatic insertion machine or the like, the electronic components stored in the case body are pulled out from the drawer opening 24.
9 rotates around the through holes 17 and 18 of the main walls 11 and 12 as central supports in response to the tensile force, so that the electronic components are smoothly and continuously pulled out of the case body.

It goes without saying that the taped electronic component storage body of the present invention is not limited to those of the above embodiments, and may be modified as appropriate without changing the gist of the present invention.

For example, when forming the case body, the side wall bodies do not necessarily have to be provided at four locations as in the embodiment, but may be provided at at least two opposing locations.

In this case, there is no need to provide a special outlet for the taped electronic component as in the second embodiment, and the electronic component may be pulled out arbitrarily from a place where the side wall body is not provided.

Furthermore, if the cover 25 shown in FIG. 5 is formed into a protrusion at the portion of the cover 25 that is located inside the through hole, as shown in FIG. 6, the rotation of the rotating shaft will be made easier.

Furthermore, in fixing the rotating shaft 20, 21 to the winding core 19, in each of the above embodiments, one end of the rotating shaft is inserted into a hole in the winding core. A hole may be formed in the rotating shaft, and the side portion of the winding core may be fitted into the hole.

The point is that the rotating shafts 20, 21 should be fixed to the sides of the winding core 19 so that it can be rotatably attached to the case body.

As explained above, in the taping electronic component storage body of the present invention, the winding core is inserted into the through hole provided in the main wall facing the surface of the case by inserting the rotary shafts fixed to both sides of the winding core. Since it is rotatably attached to the case body, the following various excellent effects can be achieved.

In other words, even if more force than necessary is applied to the winding core when pulling out the taped electronic components to the outside of the case body, the through hole will always remain in the predetermined position as long as the case body itself is not destroyed. Since the taped electronic components will not fall off from the case body and become impossible to pull out, the device is particularly suitable for being incorporated into an automatic insertion machine or the like.

In addition, in order to attach the winding core to the case body, it is only necessary to provide a through hole in the earthen wall body and secure one end of the rotating shaft inserted into this through hole to the side of the winding core, so special assembly is required. There are no steps to take into account, and assembly is extremely easy.

Furthermore, since the inner circumferential surface of the through hole in the main wall is provided with a coating that has a very smooth surface, the rotation of the winding core is extremely smooth, and the through hole is reinforced and the case is smooth. It has various effects such as making the body stronger.
