Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a safety mechanism, and more specifically, to a safety mechanism for starting and stopping power when connecting and disconnecting a connector of a connector-connected power supply device that is easy to replace and maintain. In particular, in systems where input/output lines are multi-connected and several power supplies are operated in parallel, it is safe and suitable for hot-line replacement of one power supply.
It is about the mechanism.

[Background of the invention]

Connector connection type that allows parallel operation When performing live exchange under power supply voltage, normally, after connecting the input/output connector, turn on the input switch to start up, disconnect the input switch, stop output, and then disconnect the connector. This prevents unnecessary noise voltage from being generated at the output of the power supply during operation, and prevents excessive current from flowing to the connector. This has the disadvantage that it generates noise voltage and excessive current in the output of the connector, and also causes deterioration and damage to the connector.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a safety mechanism for a connector-connected power source that eliminates troubles caused by erroneous operation by mechanically ordering the connection of the connector and the switching on/off of the switch.

[Summary of the invention]

In the present invention, a slide plate is further provided on the mounting surface of the connector and switch, and a fitting hole of the same shape as the connector and switch is provided in the slide plate only when the slide plate can slide correctly.

The operating procedure can be mechanically fixed by a slide plate into which a switch can be inserted and fitted.

[Embodiments of the invention]

Hereinafter, one embodiment of the safety mechanism of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the safety mechanism of the present invention includes a cable connection case 1, an input connector 2, an output connector 3.
A fuse connector seat 4 and a check terminal board 5 are each mounted on the bottom plate 6 of the casing, and these are connected to the input and output of a power supply device (not shown) to which this connection casing is mounted.

A slide plate 9 is attached to the opening side of the cable connection case 1 so as to be slidable in the vertical direction via a plurality of guide protrusions 8 formed at regular intervals on a pair of side plates 7 of the case. , the slide plate has a height of about 1/2 of the height of the housing, and the connector is placed at the same position as the output and input connector seats 2 and 3 arranged vertically from the upper edge side. The input and output connectors to be attached to the seats are installed using a notch 10 that is narrower than the diameter of the ring and slightly wider than the diameter of the support portion of the connector other than the ring, and a notch 10 that is slightly wider than the width of the check terminal board 5. A wide notch 11 is provided, and a rectangular hole 12 slightly larger than the fuse fitting which also serves as a switch and which is attached to the fuse fitting seat 4 is bored on the lower edge side between these two notches.

This slide plate 9 can be slid up and down when the input and output connectors 13 and 14 are attached to the respective connector seats 2 and 3, and the slide plate 9 can be slid up and down as shown in FIG. The fuse connector 15 can be inserted into the fuse connector seat 4 only when it is raised upwards, and when it is lowered, the upper edge of the slide plate 9 touches the fuse connector seat 4 as shown by the two-dot chain line in FIG.
It is impossible to insert the heating plug 15 into the plug seat.

The safety mechanism of the present invention has the above-mentioned configuration, and the sequence of plugging/detaching operations using this safety mechanism will be explained below.

Figure 1 shows a person, a person at the output connector seats 2 and 3, and an output connector 13.1.
4 is inserted, the mounting on the plug side is fixed with a ring,
When the connectors are completely attached to both liquid valve seats, the slide plate 9 can be slid upward, and with the slide plate lifted, the fuse connector 15 is inserted into the fuse connector seat 4 through the hole 12. The plug is completely inserted in a state in which it slightly protrudes from the hole 12, and the slide plate 9 is locked thereto and does not fall.

In this state, the mounting rings for both the input and output connectors 13 and 14 are located below the slide plate, and in this state, both connectors cannot be removed. When turned on, an input is supplied to a power supply device (not shown) via a λ force connector, and an output is taken out via an output connector.

In other words, hot wire replacement cannot be performed while the power supply device is operating.

If you want to turn off or turn on the output from the power supply device, or remove the output connector, pull out the fuse connector 15 from the second fuse connector seat 4 and the slide plate 9 as shown in the figure. lowers, the input to the power supply and the output from the power supply are cut off, and in this state the input and output connectors 13
, 14 can be removed by turning the ring.

If the heating connector is not removed in this way, in other words, it will not be possible to remove the connector from the connector seat while the line is live.

〔Effect of the invention〕

According to the present invention, it is possible to turn on the switch after the connector is connected, and it is possible to change the order in which the connector can be removed after the switch is removed, which prevents power failure and damage to the connector due to incorrect operation. This has the effect of preventing system failure.
