[Structure] After the lock 2 is attached to the side plate 1, the device is covered with a cover 5 and fixed by plastic deformation of the attachment portions 5a and 5b of the cover 5, so that the cover attachment portions 5a and 5b can be disassembled after assembly. A trace due to the plastic deformation of is clearly left on the cover 5.

Description

[Detailed description of the device]

【０００１】[0001]

[Industrial applications]

この考案は回路遮断器インターロック装置に関するものである。 This invention relates to a circuit breaker interlock device.

【０００２】[0002]

[Prior Art]

従来のこの種の回路遮断器のインターロック装置を図２について説明する。図において、１は機構部を保持する側板、２はインターロック用の錠、３は錠取付板、４は錠取付板３を側板１に取付けるための取付ネジである。これらの部品は遮断器本体内部に取付けられている。 A conventional interlock device for a circuit breaker of this type will be described with reference to FIG. In the figure, 1 is a side plate for holding the mechanical portion, 2 is a lock for interlock, 3 is a lock mounting plate, and 4 is a mounting screw for mounting the lock mounting plate 3 on the side plate 1. These parts are installed inside the breaker body.

【０００３】[0003]

[Problems to be solved by the device]

従来の回路遮断器のインターロック装置は以上のように遮断器本体内部に構成されているので、取付ネジ４による部品の取付が行われていた。しかしながら、従来のインターロック装置を遮断器表面に取付ける場合、ネジ取付では簡単に取付け取外しができるのでインターロック装置としての信頼性に欠けるという問題点があった。 Since the interlock device for the conventional circuit breaker is configured inside the breaker body as described above, the parts are mounted by the mounting screws 4. However, when the conventional interlock device is mounted on the surface of the circuit breaker, there is a problem that the interlock device lacks reliability because it can be easily mounted and dismounted by screw mounting.

【０００４】この考案はかかる問題点を解決するためになされてもので、錠取付後に取付けたカバーに明らかに取外したときの痕跡が残るようにしてインターロック装置としての信頼性が得られる回路遮断器のインターロック装置を得ることを目的とする。The present invention has been made in order to solve such a problem, so that the reliability as an interlock device can be obtained by leaving a trace when the cover is obviously removed after the lock is attached. The purpose is to obtain an interlock device for a circuit breaker.

【０００５】[0005]

[Means for Solving the Problems]

この考案に係るインターロック装置は、錠取付後カバーにて装置を覆い、かつカバー取付部の塑性変形により固着するようにしたものである。 In the interlock device according to the present invention, after the lock is attached, the cover is covered with the device, and the cover attachment portion is fixed by plastic deformation.

【０００６】[0006]

[Action]

この考案においては、カバー取付部の塑性変形によりカバーを取付けるために、組立後分解を行うとその痕跡がカバーの取付部に明確に残る。 In this invention, since the cover is attached by plastic deformation of the cover attaching portion, when the cover is attached and disassembled, a trace thereof is clearly left on the cover attaching portion.

【０００７】[0007]

【Example】

この考案の一実施例を図１について説明する。図１はカバー取付前の状態を示す図であり、前記従来のものと同一部分には同一符号を付して説明を省略する。図において、５はカバーで、その取付部５ａを側板１の取付穴１ａへ差し込みその端部を折り曲げて固着する。６は名板で、その凹部６ａをカバー５の取付部５ｂと位置決めした後取付部５ｂを折曲げて固着する。これにより錠取付ネジ４はカバー５類に完全に覆われてしまい安易にインターロック装置を分解することが出来なくなる。そして、カバー５の取付部５ａ，５ｂを伸ばして元に戻せば分解は可能であるが、特に取付部５ｂ部分は意匠面でもあり、折り曲げられた取付部５ｂ部分を元に戻し再度折り曲げることは困難である。さらに折り曲げ部に凹凸が出来るので分解した痕跡が明確に残る。 One embodiment of this invention will be described with reference to FIG. FIG. 1 is a view showing a state before the cover is attached. The same parts as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted. In the figure, 5 is a cover, and its mounting portion 5a is inserted into the mounting hole 1a of the side plate 1 and its end portion is bent and fixed. Reference numeral 6 is a name plate, and after the concave portion 6a is positioned with the mounting portion 5b of the cover 5, the mounting portion 5b is bent and fixed. As a result, the lock mounting screw 4 is completely covered by the covers 5 and the interlock device cannot be easily disassembled. The cover 5 can be disassembled by extending the mounting parts 5a and 5b and returning it to the original position. Especially, the mounting part 5b is also a design surface, and it is not possible to return the bent mounting part 5b to the original position and bend it again. Have difficulty. Furthermore, since the bent portion has unevenness, the disassembled trace is clearly left.

[Effect of the device]

以上のように、この考案によれば装置組立後において分解すると明確にカバーに痕跡が残り、インターロック装置の信頼性が得られるという効果がある。 As described above, according to the present invention, when the device is assembled and then disassembled, the traces are clearly left on the cover, and the reliability of the interlock device can be obtained.
