[Detailed explanation of the invention] [Table of contents] - Overview - Industrial application field - Conventional technology - Problems that the invention aims to solve - Means for solving the problems - Effects - Examples - Effects of the invention [ Overview] A switch structure that enables emergency disconnection switches installed on the front decorative panel of computers, etc. to be restored from the front of the decorative panel.

[Industrial application field]

The present invention relates to an emergency disconnect switch (EPO switch) for computers, etc., and more particularly to a switch return means for restoring the switch from a disconnected position to a normal position.

[Conventional technology]

The central control unit of a computer system is equipped with an emergency disconnect switch in case of an emergency such as an earthquake or fire, or when the power to the entire computer system must be cut off for some reason. Such an emergency cut-off switch is designed to prevent anyone other than the operator from accidentally restoring the switch after the switch is cut off and before the cause of the switch is removed.

The configuration of a conventional emergency disconnect switch is shown in FIG. Figure a is a longitudinal sectional view, and figure b is a rear view. A switch unit 2 is fixed to a decorative panel 1 constituting a front door of a computer or the like. The switch unit 2 includes a switch body 6 fixed to a housing 3 via a support plate 7, and a switch lever 5 connected to the switch body 6. The switch lever 5 is disposed within a frame 4 provided within the housing 3, and performs a switching operation between a normal position (dotted line) and a cutting position (solid line) as shown by arrow A.

In an emergency, the switch lever 5 is operated from the front of the switch unit 2 (left side in Figure A) to switch from the normal position (dotted line) to the cutting position (solid line). To restore the switch after removing the cause of the emergency, open the decorative panel 1 (front door) and insert a pin etc. into the switch unit 2 from the back of the switch unit 2 through the gap between the switch body 6 and the housing 3. Lever 5
The switch lever 5 was returned to its normal position by pressing the lower back side of the switch lever 5 (arrow B).

[Problem that the invention attempts to solve]

With conventional EPO switches, there is almost no space between the tip of the switch lever at the cut position and the lower inner surface edge 4a of the frame 4, making it impossible to restore the switch from the front of the decorative panel. . Therefore, restoration work after the switch is disconnected is troublesome and requires time and effort.

The present invention was devised in view of the drawbacks of the prior art described above, and has a configuration that makes it difficult for non-regular workers to perform front restoration operations, while allowing authorized workers to perform switch restoration work from the front of the decorative panel. The purpose is to provide an emergency disconnect switch.

[Means for solving problems]

In order to achieve this purpose, the present invention fixes a switch main body having a switch lever to a switch housing, a frame body surrounding the switch lever is mounted inside the switch housing, and the switch housing is used as a decoration for an electronic device. In an emergency disconnection switch fixed to a panel, a switch return means that enables the switch lever to be restored from the outside of the decorative panel after being disconnected is connected to the frame body movable in the operating direction of the switch lever and the frame body. and a key means operated from the front of the decorative panel for moving the decorative panel,
It is characterized in that the switch lever can be restored from the cut position to the normal position by moving the frame body using the key means.

[Function] By using a specific key, the switch lever of the EPO switch can be restored from the front (outside) of the decorative panel. A third party who does not have a specific key cannot perform recovery operations.

〔Example〕

FIG. 1 shows the configuration of an embodiment of the present invention. In this embodiment, a gap 12 is provided in the frame mounting portion of the housing 3 of the switch unit 2, so that the frame 4 can be moved up and down. This frame 4 is connected to a key switch 10 via a link 9. This key switch 10 is operated by a key 11 from the outside of the decorative panel 1. At the cut position (solid line) of the switch lever 5, the lower member of the frame 4 comes into contact with the switch lever 5 (state shown in the figure).
The position of is determined. The rest of the configuration is the same as the configuration shown in FIG.

When restoring the switch, use the decorative panel 1.
Insert the key 11 from the outside, operate the key switch 10, and pull up the link 9 in the direction of arrow E. As a result, the frame body 4 rises as shown by arrow F, and the switch lever 5 is pushed up as shown by arrow H to return to the normal position shown by the dotted line. When the key 11 is released after returning, the link 9 is lowered and the frame body 4 returns to its original position.

[Effect of idea]

As explained above, in the EPO switch according to the present invention, the restoration operation can be performed from the front of the decorative panel to which the EPO switch is attached, and the restoration work can be easily performed. Further, this restoration work requires a specific key, making it difficult for a third party to perform the restoration work, and inadvertent restoration work is prevented. In addition, since restoration work is not performed from the back of the decorative panel, the degree of freedom in wiring on the back increases and high-density mounting becomes possible.
