Abstract

PURPOSE:To enable connected states of a plurality of cooling pipe coupler pint to be positively checked within short period of time and to prevent trouble caused by non-confirmation of check in the case that an actual joint of each of the pipes is checked. CONSTITUTION:A socket 3 is connected to a plug 2 fixed to a module frame 1. A limit switch 6 is fixed to the module frame 1 and its lever 6a is pushed by an amount corresponding to a insert ion margin thereby a switch is turned ON and then a displaying lamp 7 is lit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detecting attachment / detachment of cooling pipe coupler connection portions to a plurality of modules in a semiconductor conversion apparatus for water cooling.

[0002]

2. Description of the Related Art FIG. 3 is a cross-sectional view showing the structure of a conventional coupler connecting portion in this type of cooling pipe, in which 1 is a module frame and 2 is a cooling pipe plug attached to this module frame. Reference numeral 3 denotes a cooling pipe socket attached to the flexible tube 4, and 5 denotes a cooling pipe.

Next, the operation will be described. The cooling pipe plug 2 attached to the module frame 1 is connected to the cooling pipe socket 3, and the cooling pipe plug 2 and the cooling pipe socket 3 each have an automatic opening / closing valve built therein for connection. At the same time, the passage is opened and at the same time the passage is closed. The automatic opening / closing valve opens normally when the cooling pipe plug 2 and the cooling pipe socket 3 are securely connected to perform a normal cooling function. The conventional inspection of the connection between the cooling pipe plug 2 and the cooling pipe socket 3 is performed by visual inspection of each connection portion.

[0004]

In the conventional confirmation of the connection between the cooling pipe plug and the socket, it is necessary to check the connection state individually, and it is not possible to always confirm the connection state. There is a problem in that the device may be damaged if it is not securely connected.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a device that can always reliably and reliably check the connection state between the cooling pipe plug and the socket.

[0006]

A cooling pipe connecting portion detecting device according to the present invention has a limit switch or a pressure switch at the connecting portion between the plug and the socket so that the connecting state between the plug and the socket can be constantly checked. Is provided so that the connection state can be checked by an electric signal.

[0007]

In the cooling pipe connecting portion detecting device according to the present invention, by attaching a limit switch or a pressure switch for detecting the connecting state of the plug and the socket, the connecting state can be confirmed by the display confirmation by an electric signal, and the individual connecting portions can be connected. It is possible to check all at once without checking, and it is possible to detect connection failure early.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. In FIG. 1, 1 to 5 are the same as those of the above-mentioned conventional example, and therefore the description is omitted. 6 is a limit switch mounted near the plug 2 on the side surface of the frame 1, 6
a is its lever, and when connecting the cooling pipe socket 3 to the cooling pipe plug 2, when the cooling pipe socket is inserted to the regular position 3a (the position indicated by the chain line in the figure), the contact is turned on by the insertion force. It is designed to be.
Reference numeral 7 denotes a display lamp which lights up in response to the signal from the limit switch 6.

Next, the operation will be described. In FIG. 1, when the cooling pipe socket 3 is inserted into the cooling pipe plug 2 attached to the module frame 1, the insertion face of the cooling pipe socket pushes the lever 6a of the limit switch 6 to turn on the contact of the limit switch. And the display lamp 7 lights up. When the cooling pipe socket 3 is separated from the cooling pipe plug 2, the lever 6a of the limit switch 6 returns to the position before the cooling pipe socket 3 was inserted, the limit switch is turned off, and the indicator lamp 7 is turned off.

Embodiment 2. 2 shows Embodiment 2 of the present invention, in which a pressure switch 8 mounted on the plug 2 side detects cooling water pressure, and when this switch is turned on, the indicator lamp 7 is turned on. Even in this case, the same effect as that of the first embodiment can be obtained.

[0011]

As described above, according to the present invention, since the switch is attached to the cooling pipe connecting portion and the external display is made by the electric signal, a plurality of connecting portions are not required to be checked individually. The connection status can be checked simultaneously by the display means (indicator light). In addition, since the switch operates when the cooling pipe socket is inserted and connected to the proper position, incomplete connection and disconnection can be detected early, so the device can be operated without cooling. Damage to the device can be prevented.
