Description

  The present invention relates to a packaging box for power distribution equipment for storing power distribution equipment.

  Since distribution devices such as breakers have relatively low impact strength, they are carried in a state of being housed in a packing box in order to avoid damage during product transportation.

  As a conventional packing box, as shown in FIGS. 8 and 9, one thick paper is folded to form an inner lid 101, and the inner lid 101 has a through-hole through which the operation handle 103 of the breaker body 102 passes. There is generally known a type in which a space portion 106 formed between the inner lid 101 and the outer lid 105 is used as a space for enclosing a breaker accessory.

  However, in the packaging box described above, the inner lid 101 is bent downward to come into contact with the label surface on the upper surface of the breaker due to the weight of the accessories or vibration caused by transportation, and the label surface may be bent or contact surface of the inner lid 101 There was a problem such as paper dust being generated from. As a means for avoiding this problem, a buffer material may be disposed between the inner lid 101 and the label surface of the upper surface of the breaker. However, the buffer material is not preferable because the cost increases.

  Further, in the above packing box, in order to reduce the weight of accessories, the terminal cover 107 covering the terminal portion is usually packed in a state where it is attached at a predetermined position, but the size of the terminal cover 107 is the agreement breaker. Since the size of each rating differs, a dedicated packing box is required for each rating of the agreement breaker, and there is a problem in that it is not convenient.

  In addition, since the size of the breaker body is the same even if the ratings are different in the agreement breaker, for example, as in Patent Document 1, it is formed by bending a piece of paper material, and the terminal cover is covered with this terminal retainer. There is also disclosed a technique that can be used regardless of the rating of the agreement breaker by pressing the terminal part in the removed state.

  However, the technique of Patent Document 1 is inconvenient because it is not possible to secure a space for enclosing a breaker accessory such as a removed terminal cover in a packaging box that houses the breaker body.
