DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a tracking phenomenon caused by dust or the like adhering to a blade of an insertion plug in a state of being inserted into a plug receiver.

[0002]

2. Description of the Related Art Conventionally, there is a waterproof connection type for preventing rainwater or the like from penetrating into a plug receptacle in a plug-in connector normally used outdoors. There is no device for preventing the tracking phenomenon caused by dust and the like attached to the blade of the plug inserted in the plug receiver in and around the plug connector.

[0003]

In a conventional ordinary plug-in connector, dust or the like adheres to the blade of the plug inserted in the plug receiver. Fires often ignited from dust and plug connectors, leading to fires.

In addition, it is necessary that a device for preventing the tracking phenomenon has a structure that does not hinder as much as possible.

[0005] The present invention has been made to solve the above problems.

[0006]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a plug-in connector and its periphery, in which dust or the like adheres to the blade of the plug-in plug inserted into the plug receiver. It is characterized by having a retractable plate for preventing the occurrence of the problem.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

When using this retractable tracking prevention device, the fastener 5 is removed and the dust-preventing plate 1 is lowered, and when not used, the dust-preventing plate 1 is lifted up. What is necessary is just to store it by folding with the fastener 5.

In the second embodiment shown in FIG. 2, two stays 3 are provided on the decorative cover 4 for supporting and fixing the shaft rod 2 for moving the plate 1 for preventing dust or the like, or are integrated with the decorative cover 4. FIG. 2A is a perspective view of the storage-type tracking prevention device in which a fastener 5 for folding and storing the dust-proofing plate 1 when not used is provided on the decorative cover 4 when not in use, and FIG. FIG. B is a perspective view when it is not used, FIG. C is a perspective view of the plate 1 for preventing dust and the like, and a front view from the direction of the arrow;
The figure is a perspective view of the stay 3 and a front view from the direction of the arrow.

When using the retractable tracking prevention device, the fasteners 5 are removed and the dust-preventing plate 1 is lowered, and when not used, the dust-preventing plate 1 is lifted to the back. What is necessary is just to store it by folding with the fastener 5.

FIG. 3 shows a third embodiment, in which two stays 3 are provided on a wall 4 for supporting and fixing a shaft rod 2 for moving a plate 1 for preventing dust and the like. Board 1
The fastener 5 for folding and storing the
The storage-type tracking prevention device provided in FIG.
FIG. 1 is a perspective view when it is used, FIG. 2B is a perspective view when it is not used, FIG. 2C is a perspective view of a plate 1 for preventing dust and the like and a front view from the direction of an arrow, and FIG. It is a front view from the direction of the arrow.

When using the retractable tracking prevention device, the fasteners 5 are removed and the dust-preventing plate 1 is lowered, and when not used, the dust-preventing plate 1 is lifted to the back. What is necessary is just to store it by folding with the fastener 5.

FIG. 4 shows a fourth embodiment in which a plug 2 is provided with a hole 2 through which a plate 1 for preventing dust and the like slides back and forth.
And a stopper 4 is provided on the dust-repelling plate 1 to prevent the dust-reducing plate 1 from entering deeper than the surface of the plug receiver 3 when the slide is stored when not in use. FIG. 4A is a perspective view of the anti-tracking device when it is used, FIG. 4B is a perspective view of the device when it is not used, FIG. 4C is a perspective view of the dust-proof plate 1, and FIG. FIG. 4 is a perspective view of a hole 2 provided in the first embodiment.

When using the retractable tracking prevention device, hold the stopper 4 and pull out the dust-preventing plate 1 toward the user. When not using the device, push the dust-preventing plate 1 into the back. You just need to store the slides.

In the fifth embodiment shown in FIG. 5, a plate 1 for repelling dust and the like and a spring 2 for sliding the plate 1 are fitted into a pedestal 3, and the pedestal 3 is fixed to the upper surface of a plug 4 or a plug. Storage type tracking in which a hook 5 for slidingly storing the dust-proof plate 1 on the pedestal 3 when not in use is provided on the dust-proof plate 1 and a string 6 is provided on the pedestal 3 when not in use. FIG. 5A is a perspective view showing a state in which a plate 1 for dust and the like is slid out from a pedestal 3 fixed to the plug 4 or integrally formed with the plug 4, FIG. B is a perspective view of a state in which a plate 1 for dust and the like is slid and stored in a pedestal 3 fixed to the plug 4 or integrally formed with the plug 4, and FIG. C is a perspective view of the pedestal 3. , D is a perspective view of the front side of the plate 1 for preventing dust and the like and an oblique view of the back side. It is a diagram.

When using the retractable tracking prevention device, the plug 6 is inserted into the plug receiver and fixed to the plug 4 or the string 6 provided on the pedestal 3 integrally formed with the plug 4. When not in use, the user removes the hooks 5 provided on the dust-preventing plate 1 and pushes the dust-preventing plate 1 into the pedestal 3, and hangs the string 6 on the hooks 5 so as to be slid and stored.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and the structure, shape, number, etc. may be arbitrarily changed without departing from the gist of the present invention. You can do it.

[0019]

As described above, the present invention provides a plug-in type connector and a stowable type provided around the plug-in connector for preventing dust and the like from adhering to the blade of the plug-in plug inserted into the plug receiver. The following effects can be obtained.

Since the tracking phenomenon can be prevented, there is no danger of fire from dust or the like or fire from the plug-in connector.

Since the plate for preventing dust and the like is of a retractable type, a device for preventing the tracking phenomenon is not obstructed as much as possible.
