Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a module evaluation device with an optical fiber for evaluating and testing a sample housed in a test tank, and more particularly, to a cord which is easy to put a sample into and out of a test tank and which is attached to the sample. The present invention relates to an optical fiber-equipped module evaluation device that can be easily pulled out of a test tank without damaging the class.

[0002]

2. Description of the Related Art A test chamber such as a thermostat is a container or a room for placing an object to be subjected to various evaluation tests (hereinafter, referred to as a sample) in a controlled predetermined environment. For example, the thermostatic bath includes a space inside the bath surrounded by a heat insulating material, and a temperature adjusting unit for uniformly adjusting the space inside the bath to a desired temperature. As shown in FIG. 6, a test chamber 61 such as a conventional thermostat is provided with a draw-out hole 62 for pulling out cords connected to the sample out of the test chamber. As shown in FIG. 7, the cords 63 connected to the sample (not shown) accommodated in the test tank 61 are pulled out of the test tank 61 through the draw-out hole 62, and the cords 63 are removed by a measuring device or the like. It is possible to connect to the control device of the sample. In this way, the evaluation device using the test tank 61 can evaluate by examining the properties and operating states of the sample under a predetermined environment. However, the drawer hole 62
When the size of the test piece is too large, the air inside and outside the test tank is circulated and it becomes difficult to maintain the environment inside the test tank.

[0003]

In the conventional test tank, if nothing is connected to the opposite end of the cords 63 from the sample, the cords 63 can be easily pulled out as shown in FIG.
Can be withdrawn from. However, as shown in FIG. 8, when the size of the sample (not shown) connected to one end of the cords 63 and the size of the connector 64 connected to the opposite end are both larger than the drawer hole 62, It is not feasible to pass the cords 63 through the drawer hole 62 as shown. Further, even when the cords 63 can be passed through the drawer hole 62, if the number of the cords 63 increases, the workability of passing the cords 63 through the drawer hole 62 becomes extremely poor.

The cords 63 can be easily attached to and detached from a sample, while others can be difficult. For example, a module with an optical fiber is a module in which an optical fiber is connected to a module including an optical circuit element and the like, and it is not easy to attach and detach, and it is troublesome to attach and detach during an evaluation test. Also, if the optical fiber is integrally fixed to the module,
Separation is not possible. Also, when an assembly in which an optical fiber is added to a module is to be evaluated and tested, it is not an evaluation test if the assembly is separated.

On the other hand, in order to omit the operation of passing the cords 63 through the draw-out holes 62, the cords 63 may be pulled out from a door (not shown) at the front of the test tank 61.
When the front door 65 is closed, a force may be applied to the cords 63 to cause deformation or damage. In particular, codes 63
Is very likely to be broken when is made of an optical fiber.

Accordingly, an object of the present invention is to solve the above-mentioned problems, to provide an optical fiber which allows a sample to be easily taken in and out of a test tank and which can be easily pulled out of the test tank without damaging cords attached to the sample. To provide an attached module evaluation device.

[0007]

In order to achieve the above-mentioned object, the present invention provides a test tank containing a module to which a cord such as an optical fiber is attached as a sample. A sample door for forming a sample inlet / outlet for taking in / out and a sample door for closing the sample inlet / outlet are provided. A gap is formed to allow the cords to escape.

[0008] The sample door may be provided independently of the tank body of the test tank, and the sample door may be fitted into the sample access hole to close the sample access hole.

[0009] By forming a notch in the sample door from the edge serving as the closing portion, the gap is formed when the sample door is closed,
Furthermore, a nesting door smaller than the notch is provided,
By fitting this nesting door into the notch,
The gap may be reduced.

[0010] The test tank may be a thermostat, and each door may be made of a heat insulating material.

[0011]

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

As shown in FIG. 1, the thermostatic bath 1 used in the module evaluation apparatus with an optical fiber in the present invention comprises:
It has a rectangular parallelepiped tank body 2, and the front of the tank body 2 is a front door 3 that can be freely opened and closed by a hinge. Although not shown, when the front door 3 is opened, a door opening communicating with the thermostat is exposed. The front door 3 is formed with a rectangular sample entrance / exit hole 4 for taking in / out a module with an optical fiber. In addition, independently of the bath 2 of the thermostatic bath 1, the sample access hole 4
A sample door 5 for closing the door is provided. The sample door 5 is formed to have almost the same size as the sample access hole 4.
The sample door 5 can be closed by fitting the sample door 5 into the sample door 4. Therefore, the four edges of the sample door 5 and the sample entrance / exit hole 4 become the mutually closed portions 6. The sample door 5 is cut from one of the edges to be the closed portion 6 (here, the right edge) to a predetermined width (vertical direction) and a predetermined length (horizontal direction). A notch 7 is formed. In this figure, the notch 7 is formed substantially at the center of the edge of the sample door 5 in the vertical direction, so that the sample door 5 has a concave shape, but the cut 7 is formed anywhere on the edge of the sample door 5. Is also good. The notch 7 forms a gap having the same size as the notch 7 when the sample door 4 is closed by the sample door 5. Further, independently of the sample door 5, the notch 7
A smaller nesting door 8 is provided. The nesting door 8 is substantially the same in width as the cut portion 7 and shorter in length than the cut portion 7. When inserted, a small gap due to the difference in length is formed. The sample door 5 and the nest door 8 are
Like the bath 2 of the thermostat 1, it is made of a heat insulating material.

FIG. 2 shows a state in which each door of the thermostatic bath of FIG. 1 is closed. As shown in the drawing, by closing the front door 3, closing the sample door 5, and further closing the nesting door 8, the door opening of the thermostatic oven 1 forms a small gap 9 formed in a part of the cut portion 7.
It will be sealed except for. The gap 9 becomes a space for the optical fiber extending from the inside of the thermostat 1 to the outside of the thermostat 1. In this figure, the nesting door 8 is fitted rightward toward the cutout 7 so that the sample door 5
Although the gap 9 is formed in the center of the surface of, the gap can be formed even if the gap 9 is fitted to the left.

Here, a procedure for accommodating a module with an optical fiber in the thermostat 1 will be described. First, the nesting door 8 and the sample door 5 are removed from the state of FIG. 2 to obtain the state of FIG. 1, and the module 10 with an optical fiber is put into the thermostat 1 through the sample inlet / outlet 4. As a result, as shown in FIG. 3, the module 11 of the module 10 with the optical fiber is in the thermostat 1, the optical fiber 12 extends from the thermostat 1 to the outside of the thermostat 1, and the module 1 of the optical fiber 12
The connector 13 attached to the end opposite to 1 is outside the thermostat 1. Next, the sample door 5 is attached to the thermostat 1. At this time, the optical fiber 12 is set to fit in the gap formed by the cutout portion 7. That is, as shown in FIG. 4, the optical fiber 12 is
The optical fiber 12 can escape into the gap. further,
The nest door 8 is attached to the thermostat 1. At this time, the optical fiber 12 is accommodated in the small gap 9 caused by fitting the nesting door 8. Upon completion, as shown in FIG. 5, the optical fiber 12 extends from the inside of the thermostat 1 to the outside of the thermostat 1 through the small gap 9.

[0015] In the above procedure, from the time when the module 10 with the optical fiber is put into the thermostat 1 to the time when it is completed,
The optical fiber 12 remains attached to the module 11 and the connector 13 remains attached to the optical fiber 12. That is, the optical fiber 12 to which the module 11 and the connector 13 are larger than the conventional drawer hole is inserted into the gap 9 small enough to allow only the optical fiber 12 to pass without causing the attaching / detaching operation to the module 10 with the optical fiber. You can pass.

When the sample door 5 is closed, the optical fiber 12 escapes into the gap formed by the cutout portion 7.
Since the optical fiber 12 is not pinched and the size of the gap at this time is relatively large, the optical fiber 12 can be easily accommodated.

Further, since the gap is reduced by the nesting door 8, the flow of air inside and outside the constant temperature bath during operation can be extremely reduced.

Also, since the sample door 5 is provided independently of the tank body 2 and fitted into the sample access hole 4, the sample access hole 4 is provided.
It is easy to visually recognize the optical fiber 12 coming out of the optical fiber, and it is possible to avoid inadvertently sandwiching the optical fiber 12.

Further, since the operation can be performed with the front door 3 closed, the operator can approach the front of the constant temperature bath without avoiding the open front door 3, and the light can be transmitted to the constant temperature bath 1 during operation. Even when the fiber-attached module 10 is taken in and out, the flow of air inside and outside the thermostat can be reduced.

In the above-described embodiment, the evaluation apparatus performs the evaluation test by storing the module 10 with the optical fiber in the thermostatic chamber 1. The present invention can be applied to various evaluation apparatuses that perform an evaluation test while housed.

[0021]

The present invention exhibits the following excellent effects.

(1) The sample can be easily taken in and out of the test tank.

(2) Even if the sample and the connector are relatively large, the cords attached to the sample can be easily pulled out of the test tank from the small gap without damaging the cords.
