[Industrial application field]

This invention is a shielding method for optical communication module packages installed in optical communication equipment. This invention relates to an optical communication module shield case.

0002

[Conventional technology]

Figure 4 is an exploded perspective view of an optical communication module shield case showing an example of a conventional example, and Figure 5 FIG. 5 is a perspective view of the optical communication module shield case of FIG. 4 viewed from the back. subordinate Nowadays, this type of optical communication module shield case is shown in FIGS. 4 and 5, for example. As shown in FIG. Cover the plate-shaped optical communication module hackage 1 to be installed, and A notch 7 into which the body of the receptacle 2 fits is formed in a side wall that falls down from the corresponding side surface. This is a box-shaped shield case 4.

0003 In addition, this shield case 4 has walls on both walls perpendicular to the one side. A rectangular mounting portion 8a extending from the side edge of the wall is formed by cutting out and bending the protrusion. ing. This protrusion 8 is inserted into the elongated hole 9 of the optical communication module hackage 1, and Fixed by soldering. On the other hand, the mounting part 8a is inserted into the housing of the device and soldered. This optical communication module shield case was installed in the device.

[Problem that the idea aims to solve]

In the conventional optical communication module shield case described above, the shield case 4 is Cover the communication module package 1, insert the protrusion 8 into the elongated hole 9, and solder it. Therefore, when replacing the optical elements or electronic components of the optical communication module package 1, Each time, the solder on protrusion 8 must be melted, removed, and the parts replaced. There is a problem of wasting a large amount of man-hours. Also, when assembling the shield case 4, Ratio of soldering work for fixing to communication module package 1 in assembly man-hours The disadvantage is that there are many steps and it takes a lot of man-hours.

[0005] The purpose of this invention is to solve this problem by making it easy to install and remove in a short time. By providing an optical communication module shield case that is easy to clean and parts are easily replaced. be.

[0006]

[Means to solve the problem]

The optical communication module shield case of this invention mounts optical elements and electronic components. A plate-shaped optical communication module package with a receptacle attached to one side. It has a mounting surface on which the page is placed and screwed, and corresponds to the one side. A notch into which the body of the receptacle fits is formed in the side wall rising from the side surface of the receptacle. , and a box shape with fixed feet protruding from the bottom surface for attachment to the device housing. a lower case that covers the optical communication module package and includes a lower case that covers the optical communication module package; a side wall that covers both sides of the side perpendicular to the one side of the base and is secured with screws; and an upper case having. Further, the fixed foot portion may be attached to the bottom of the lower case. It is a rectangle with one side left uncut, and that side bent perpendicular to the bottom so that it protrudes. It is characterized by certain things.

[0007]

【Example】

Next, the present invention will be explained with reference to the drawings.

[0008] Figure 1 is an external perspective view of an optical communication module shield case showing one embodiment of the present invention. , FIG. 2 is an exploded perspective view of the optical communication module shield case of FIG. 1. This light path The optical communication module shield case is the optical communication module package as shown in Figure 1. Separate the upper case 4a and lower case 4b so as to wrap the Fix the optical communication module package with screws and cover it with the upper case. That is.

[0009] In other words, as shown in Figure 2, this optical communication module shield case The receptacle 2 is mounted on the mounting plate 6 on one side while mounting the child and electronic components. Installation in which the plate-shaped optical communication module package 1 that can be removed is placed and screwed. The lip is attached to a side wall having a bearing surface 3 and rising from a side surface corresponding to the one side surface. A notch 7a is formed into which the body of the septacle fits, and is attached to the housing of the device. A box-shaped lower case 4b with fixed foot parts 8b protruding from the bottom surface thereof, and a light Covers the communication module package 1 and is perpendicular to the one side of the lower case 4b. an upper case 4a having side walls that cover both side walls of the side surface and are screwed; It consists of

0010 To attach this optical communication module shield case to the equipment housing, The fixed leg portion 8b is inserted into the hole of the casing, and the fixed leg portion 8b is bent and fixed. Is it necessary? Alternatively, weld with solder, etc. In addition, the mounted parts of the optical communication module hackage 1 were replaced. To replace the upper case 4a, remove the screws on the side of the upper case 4a and remove the upper case 4a. The mounting surface of the optical communication module hackage 1 is exposed, making it easy to replace mounted parts. Wear.

[0011] Figure 3 shows the fixed feet of the lower case in the optical communication module shield case of the present invention. It is a partial perspective view which shows one Example of a part. Optical communication module in the embodiment described above The upper and lower cases of the LeShield case are all made by press processing. There is. For this reason, the fixed foot part is also easily press-formed as shown in Figure 3. , cut out one rectangular side of the bottom of the lower case 4b and fold it perpendicular to the bottom at that side. It is shaped so that it bends and protrudes. This makes it easier to attach to the device I was able to do this in a short time.

0012

[Effect of the idea]

As explained above, the present invention consists of a lower case that is attached to the housing side of the device, and an optical transmitter. The upper case covering the communication module package is installed separately, and no soldering is required. By connecting with screws, the upper case can be attached without removing it from the device housing. The mounting surface of the optical communication module package can be exposed by removing only the Therefore, the optical communication module allows for easy replacement and assembly of mounted components in a short time. This has the effect of providing a shield case.
