Abstract

PURPOSE:To hold back the force of spring back by bending an insulation sheet so that it may be box-shaped and installing some device like hook on the side of the box and a hole into which the hook may be seized. CONSTITUTION:An insulation cover 1 which comprises an insulation sheet bent in a box shape is mounted on a circuit substrate 7. The side 4 is provided with a projected part 5 and a fit-in section 6 which is inserted into a long hole 3 provided on the circuit substrate 7. Each side of the insulation sheet 1 tends to extend outward by the force of spring back, but the projected part 5 is hooked with the L-shaped hole 3 so that it may be further fitted-in, thereby preventing the extension of each side of the sheet. At the same time when external force is applied to the side 4 of the insulation sheet 1 inwardly, the side 4 is protected from the inward deformation induced by external force since the long hole 8 is installed to the circuit substrate 7 and the projected part 6 provided on the side 4 of the insulation sheet 1 is fitted into the hole 8. It is, therefore, possible to prevent the extension of each side.

う問題が、あった。The above-mentioned conventional technology does not take into consideration bending the insulating sheet etc. into a box shape, and since it is impossible to completely press bend the insulating sheet etc., when bending the insulating sheet etc. into a box shape, each side has a spring. There was a problem with it spreading due to the power of Nokutsuku.

本発明の目的は、前記、スプリンノくツクの力をおさえ
た絶縁シートの箱曲げ構造を提供することにある。An object of the present invention is to provide a box-bending structure of an insulating sheet that suppresses the force of the spring lock.

〔課題を解決するための手段〕[Means to solve the problem]

上記目的は、一つの側面に引っ掛ける形状を設け、その

板にも引っ掛ける穴を設けることで達成される。The above object is achieved by providing a hooking shape on one side surface, and providing a hooking hole on the side surface next to that side surface and also a hooking hole on the board to which it is attached.

〔作用〕[Effect]

っ掛ける形状が該側面の隣の側面の穴と嵌合する０ 〔実施例〕 以下、本発明の実施例を第１図、第２図より説明する。An insulating sheet bent into a box shape is subjected to an expanding force due to springback force. In order to withstand this force, the hook shape on the side surface of 1 fits into the hole on the side surface next to the side surface 0. [Example] Below , an embodiment of the present invention will be explained with reference to FIGS. 1 and 2.

ある長穴８に差し込むために設けた嵌合部６カエある。1 and 2, an insulating cover 1 made by bending an insulating sheet into a box shape is attached to a circuit board 7. A protrusion 5 is provided on the side surface 4 of the insulating cover 1 and a protrusion 5 is provided on the circuit board 7. There is a fitting part 6 provided for insertion into the elongated hole 8.

また、側面４の隣の側１ｉ２には、Ｌ型の穴３が、設け

い。In FIGS. 1 and 2, each side of the insulating cover 1 tends to expand outward due to springback force, but in this embodiment, the protrusion 5 is hooked into the L-shaped hole 3. Since they fit together, the insulating cover 1 can be attached to the circuit board 7 with good workability without the side surfaces spreading out.

てし家うことがない。Further, when an external force is applied to the side WJ4 of the insulating cover 1 inwardly with respect to the side surface 4, the convex portion 5 is removed from the L-shaped hole 5 and the side surface 2 is expanded due to the springback force. In the embodiment, an elongated hole 8 is provided in the circuit board 7 to which the insulating cover 1 is attached, and the insulating cover 1 is inserted into the elongated hole 8.
Since the fitting part 6 provided on the side surface 4 of the side surface 4 is inserted, the side surface 4
It does not deform inward (by external forces), and each side does not expand.
