Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an insulating cover that is installed to protect the safety of workers by shielding non-working live parts when performing repairs or expansion work in electric rooms or cubicles.

[0002]

[Prior art]

 Conventionally, it was basically done by power outages when repairing or expanding in electric rooms or cubicles, but in recent years it has become stable due to the sophistication and diversification of power usage and the rapid progress of the information society. Power supply is regarded as important, and it is difficult to carry out work due to power outages even in low-voltage work. Currently, there is an increasing number of live line proximity works that utilize electrical equipment other than those targeted for construction, but it is obligatory to shield live parts close to the work in order to prevent electric shock hazards in order to ensure the safety of workers. ing.

[0003]

[Problems to be solved by the device]

 However, conventional low-voltage protective equipment and protective equipment have problems such as workability when they are handled on-site, and they are not suitable for work in the electric room, so they are not used correctly. .

The present invention has been made in view of the above points, and it is possible to solve the above problems by providing an insulating cover that can cover a charging part very easily during construction of an electric room or the like. It is something to solve.

[0005]

[Means for Solving the Problems]

 Therefore, in the invention of claim 1, a flexible rod-like body is integrally attached to a part of the outer edge of an appropriate insulating sheet.

According to the second aspect of the invention, a flexible rod-shaped body is attached to each of a pair of outer edges of a suitable insulating sheet which face each other.

In the invention according to claim 3, a flexible rod-shaped body is attached to each outer edge of the four sides of an appropriate insulating sheet.

[0008]

[Action]

 In the insulating cover according to claim 1, a flexible rod-shaped body is applied to the upper portion of the charging portion at a substantially right angle, the flexible rod-shaped body is bent, and both ends thereof are wound around the rear portion of the charging portion, or Hook on something appropriate. This causes the insulating cover to hang down so as to cover the live part. Therefore, the charging part is covered with the insulating cover. Further, when the work is completed, the flexible rod can be folded back and removed from the locking portion, and can be used elsewhere.

In the insulating cover according to the second aspect of the invention, flexible rod-shaped portions are respectively applied to the upper and lower portions of the charging portion at substantially right angles, the flexible rod-shaped portions are bent, and both ends thereof are connected to the charging portion. Wrap it around the back of your car or hook it on something else. As a result, both ends of the insulating cover are locked by the flexible rods, and the charging portion is covered with the insulating sheet portion. Further, when the work is completed, the flexible rod can be folded back to be released from the locking portion, and can be used in another place.

In the insulating cover according to claim 3, the flexible rod-shaped body portions are respectively applied to the upper, lower, left and right sides of the charging portion, the flexible rod-shaped bodies are bent, and both ends of the flexible rod-shaped body are bent to the rear portion of the charging portion. Wrap it around or hook it on something suitable. As a result, the upper and lower ends and the left and right ends of the insulating cover are locked by the flexible rods, respectively, and the insulating sheet portion covers the charging portion. Further, when the construction is completed, the flexible rod can be folded back to be removed from the locking portion, and can be used in another place.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In the first embodiment of the present invention, a quadrilateral insulating sheet 1 in which a mesh-like synthetic resin cloth is sandwiched by a transparent synthetic resin sheet is provided with edging tapes 2 on one side, and one of these is provided. The flexible metal rod 3 is put in a synthetic resin sheet.

As shown in FIG. 3, the insulating cover of the first embodiment is such that a metal rod 3 is put on an upper portion of a charging portion 4 composed of four cables, the metal rod 3 is bent, and both ends 3a thereof are charged. The metal rod 3 is wound around the rear part of the electric part 4 and hooked on the charging part 4. This causes the seat 1 to hang down so as to cover the charging portion 4 of the low-voltage breaker (MCCB) 5, as shown in FIG. Therefore, the charging unit 4 is covered with the insulating cover.

In the second embodiment of the present invention, as shown in FIG. 5, a quadrangular insulating sheet 6 in which a mesh-like synthetic resin cloth is sandwiched with a transparent synthetic resin sheet is provided with edging tape on four sides. 7, a flexible metal rod 8 was provided on each of the upper and lower sides, and the central portion thereof was placed in a synthetic resin sheet and both ends thereof were projected outward. Further, the base portions of the U-shaped flexible metal rod 9 are integrally fixed to the edging tapes 7 on the left and right sides of the insulating sheet 6.

As shown in FIG. 6, the insulating cover of the second embodiment is applied with metal rods 8 and 9 on the upper and left and right sides of a charging portion 10 composed of three cables, and the metal rods 8 and 9 are folded. Then, the respective tip portions 8a and 9a are bent around the rear portion of the charging portion 10. As a result, the upper and lower ends and the left and right ends of the seat 6 are locked by the metal rods 8 and 9, respectively, and the charging portion 10 is covered with the seat 6.

Although the flexible metal rod 3 is provided only on the upper end of the quadrilateral insulating sheet 1 in the first embodiment, the metal rod 3 may also be provided on the lower end edge facing the upper end. . Further, the flexible metal rod of the above embodiment is not limited to this, and a rod-shaped body made of an appropriate material can be used as long as it has flexibility. Further, the insulating sheet is not limited to that of the above-mentioned embodiment, and an appropriate material and an appropriate shape may be adopted.

[0016]

[Effect of device]

 According to the invention of claim 1, when the charging portion is covered with the insulating sheet, the flexible rod-shaped body of the insulating cover of the invention is applied substantially horizontally to the upper portion of the charging portion, and the flexible rod-shaped body is attached. By bending it, either end of the charging part can be locked, or it can be locked to an appropriate object close to the charging part and the lower part can be hung so that the charging part is shielded by the cover and the charging Allows workers to safely carry out electrical work in areas close to the section. Moreover, the flexible rod-shaped body integrated with the insulating sheet can be locked to an appropriate object, and the installation work of the insulating cover is extremely simple and quick without the need to prepare other bind wires, tapes, tools, etc. You can Also, the flexible rod can be returned to a straight line again and used many times.

In addition to the effect of the first aspect, the device of the second aspect can lock the insulating cover at the upper and lower parts of the charging part, and the insulating cover of the charging part can complete the shielding.

According to the invention of claim 3, in addition to the effect of claim 1, the insulating cover can be locked at the upper and lower parts of the charging part and both the left and right sides, and the insulating cover can be used regardless of the shape or structure of the charging part. The bar can be locked and the shielding is even more complete.
