Description

The present invention relates to a protective cap that protects a site to be protected of a structure and a structure housing method that houses the structure.
Hereinafter, an optical module device (hereinafter simply referred to as “optical module”) is taken as an example of a structure, and a protective cap for the optical module and a method for housing the optical module will be mainly described.

In the optical module packaging apparatus, it is necessary to attach a protective cap to the light receiving unit and the light emitting unit from the viewpoint of protecting the light receiving unit and the light emitting unit from dust and damage.
The optical module packaging device is stored in a storage tray or the like with a protective cap attached, and shipped with a cover (for example, Patent Document 1).

  In a conventional packaging device, the optical module is stored in a storage tray or the like, for example, in order to avoid inadvertent dropping of the optical module, for example, a structure in which a product is fitted and held.

Utility model registration No. 3077678

When taking out an optical module from such a packaging apparatus, the taking-out operation | work using tweezers etc. was required for the magnitude | size of the optical module, the accommodation space | interval, and the fitting structure.
The optical module storage tray is provided with a concave storage section along the outline of the optical module with the protective cap attached. When the optical module is stored in the storage tray, the optical module is placed in the storage section with the protective cap attached. It is inserted.
In order to prevent the optical module from falling off, there is almost no gap between the optical module and the storage unit, and the interval between the storage units is usually narrow in order to increase the storage efficiency of the storage tray.
For this reason, when taking out the optical module from the storage tray, the operator needs to take out the optical module using a tool such as tweezers.
For this reason, conventionally, there is a problem that the unpacking work and the number of work for taking out increase.
In addition, since tools such as tweezers are used, there is a problem that a lot of labor and time are required for the taking-out operation.
In addition, the optical module may fall from the tool during removal, and the optical module may be damaged.

  The main object of the present invention is to solve such problems, and it is a main object of the present invention to facilitate the removal of the structure.

The protective cap according to the present invention is:
A protective cap that is fitted to a protection target part of the structure and protects the protection target part,
It is characterized by providing a protruding part standing on the outer surface.

  According to the present invention, since the protruding portion standing on the outer surface of the protective cap is provided, it is possible to pull out the structure from the storage tray by picking up the protruding portion by hand, such as tweezers. The structure can be easily taken out without using a tool.

Embodiment 1 FIG.
In the present embodiment, a protective cap and an optical module housing method in which an unpacking operator can manually remove an optical module without using a tool such as tweezers will be described.

  FIG. 1 shows an example of an optical module equipped with a protective cap in the present embodiment.

Reference numeral 21 denotes an optical module, reference numeral 22 denotes a protective cap, and reference numeral 23 denotes a handle 23 which is a protrusion provided on the outer surface of the protective cap 22.
In the optical module 21, a protective cap 22 is attached to a portion to be protected that needs to be protected.
Specifically, a protective cap 22 is attached to the light receiving unit and the light emitting unit of the optical module 21 in order to protect it from damage caused by dust or external force.
The protective cap 22 is made of resin, and the handle 23 is integrally formed with other parts of the protective cap 22.
The material of the protective cap 22 may be a resin that has already been widely used.
It is assumed that the protective cap 22 is made of a resin material that is easily elastically deformed.
As shown in FIG. 1, the handle 23 has a rod shape and stands up.
Note that the handle 23 is not limited to a bar shape as long as it is a shape that the unpacking operator can pinch with the hand.
It may be plate-shaped or hump-shaped.
Further, even in the case of the rod-shaped handle 23, a triangular cross section or a quadrangular cross section may be used instead of a circular cross section as shown in FIG.
As will be described later, since the optical module 21 is taken out by pulling the handle 23 when the optical module 21 is taken out, the handle 23 is made of a material, a size and a shape that are not broken by a normal pull by a human hand. There must be.

The optical module 21 to which the protective cap 22 is attached is stored in a packaging device for transportation, for example, a storage tray.
FIG. 2 shows a state where the optical module 21 is stored in the storage tray.

In FIG. 2, reference numeral 11 denotes a storage tray, and reference numeral 12 denotes a storage portion in the storage tray 11.
The storage unit 12 is a concave holder along the outline of the optical module 21 with the protective cap 22 fitted therein.
The optical module 21 is housed in the housing portion 12 with the protective cap 22 fitted therein.
The storage unit 12 has a structure for fitting the optical module 21 to prevent the optical module 21 from being accidentally dropped from the storage tray 11.
That is, there is almost no gap between the optical module 21 and the storage portion 12 to prevent the optical module 21 from falling off.
When the optical module 21 is stored in the storage tray 11, the cover 10 is attached to the storage tray 11 to obtain a packaging state.
The storage tray 11 and the cover 10 may be existing ones.

FIG. 3 shows a state where the cover 10 is put on the storage tray 11.
As shown in FIG. 3, the optical module 21 is shipped with the protective cap 22 attached, stored in the storage tray 11, and covered with the cover 10.

Before the cover 10 is covered, as shown in FIG. 2, the handle 23 stands up because it is not pressed by the cover 10, but when the cover 10 is covered, it is pressed by the cover 10 as shown in FIG. 3. Then, the handle 23 is elastically deformed and falls down.
If the handle 23 is not elastically deformed, the handle 23 becomes a hindrance when the cover 10 is closed. Therefore, the cover 10 needs a structure (hole or the like) for releasing the handle 23.
However, since the protective cap 22 is formed of a resin that easily elastically deforms, as shown in FIG. 3, even if the cover 10 is closed, the handle 23 can be flexibly deformed and the cover 10 can be covered without any trouble. is there.

When taking out the optical module 21 from the storage tray 11, the optical module 21 can be taken out without working tools such as tweezers by pulling up the handle 23.
That is, in the unpacking work, the unpacking operator raises the cover 10 as shown in FIG. 2 from the state where the cover 10 of FIG. 3 is put on.
When the cover 10 is lifted, the handle 23 that has been tilted is released from being pressed by the cover 10 and thus stands up in the direction in which the optical module 21 is taken out as shown in FIG.
For this reason, the unpacking operator can pick up the handle 23 of the protective cap 22 of each optical module 21 by hand.
Since the protective cap 22 is fitted into the optical module 21, when the handle 23 is pulled, the optical module 21 is taken out from the storage portion 12, and the optical module 21 can be taken out without tools such as tweezers.

Conventionally, as shown in FIG. 6, a protective cap 22 without a handle 23 is attached to the optical module 21.
For this reason, when taking out the optical module 21 with the protective cap 22 shown in FIG. 6 from the storage tray 11, a tool such as tweezers is required.
However, in the present embodiment, by picking up the handle 23, the optical module 21 can be easily removed from the storage tray 11 without using a tool such as tweezers.

  As described above, the protective cap and the storage method according to this embodiment significantly improve (1) protection of the optical module by the cap function and (2) workability of taking out the optical module.

  In addition, since the optical module can be picked up by the handle by hand, there is little risk of dropping the optical module.

1 is upright in the pulling direction, but may be tilted from the pulling direction as exemplified in FIG.
In addition, FIG. 4 shows an example of the handle 23 standing upright in the X direction, but the handle 23 standing up in the Z direction may be used.

Moreover, you may provide the handle 23 in the front-end | tip part of the protective cap 22 like FIG.
When the handle 23 is provided at the tip of the protective cap 22 as shown in FIG. 5, the handle 23 is placed at the upper half of the protective cap 22 so as not to obstruct the optical module 21 when stored in the storage unit 12. It is necessary to provide it.

  As described above, in this embodiment, the optical module packaging apparatus including the tray for holding and fixing the product, the cover, and the cap with the handle has been described.

  Further, it has been explained that the handle of the cap with the handle of the packaging device is easily elastically deformed by covering the tray.

  The description has been made so far using the optical module as an example of the structure. However, the present invention is not limited to the optical module, and any structure that fits a protective cap on a portion to be protected can be used. It becomes the object of application of the invention.

  10 cover, 11 storage tray, 12 storage section, 21 optical module, 22 protective cap, 23 handle.
