Abstract

PURPOSE:To make effective a non-conductive condition of a switch by an operating movement of a cover by constituting an operating and closing interlocking switch of a cover as a short circuit piece of two contacts of a switch by a fastening plate engaging with a hook and fixed to the cover. CONSTITUTION:When a cover closes by drawing two dot chain line trace, a fastening plate 3 fixed to the cover 2 abuts against an inclined surface of the hook 4, the hook 4 moves against an energizing force of a spring or the like, and when a window section of the fixing plate 3 passes through the inclined surface of the hook 4, the hook 4 returns by the energizing force to engage the fixing plate 3 by the window section. At the same time, the fixing plate 3 contacts two contacts 5a, 5b of a switch main body 5 disposed in the vicinity of both sides of the hook 4. Further, when engaging the fixing plate, the contacts 5a, 5b are pressed open and a contact pressure with the fixing plate 4 is maintained by a resilient force provided in the contacts 5a, 5b. When the hook 4 is oscillated from the engaging condition by an engagement releasing thumb 6, the engagement of the fixing plate 3 is released to open the cover. Thereby, the contacts 5a, 5b are effectively non-conductive by opening the cover.

を提供するものである。Problems to be Solved by the Invention However, with the above configuration, the switch becomes conductive when the rod-like projection is caught on the main body, or simply by pressing the rod-like projection, so the laser diode becomes in a light-emitting state and is therefore safe. In order to solve the above-mentioned problems, the present invention provides a lid opening/closing interlocking switch that can reliably turn the switch into a non-conducting state by opening the lid. It is.

に配するスイッチ本体である。Operation: Due to the above-described configuration, the fastener fixed to the lid separates from the hook when the lid is opened, so that the two contacts arranged near the hook are never short-circuited. An example of the lid opening/closing interlocking switch will be explained with reference to the drawings.0 The first figure shows the lid opening/closing interlocking switch according to the embodiment of the present invention.In Figs. 1 and 2, 1 indicates the main body. , 2 is a lid rotatably supported on the main body 1, 3 is a fastener fixed to the lid 2,
4 is a hook pivotably supported on the main body 1, and 6 is the main body 1.
This is a switch body that is fixed to the switch body and arranged near both sides of the two contacts sa and sb2 hook 4.

以上のように構成された蓋の開閉連動スイッチについて
動作を説明する。The operation of the lid opening/closing interlocking switch configured as described above will be explained.

いることを示している。At this time, the fastener 3 simultaneously comes into contact with the two contacts 5&, 5b of the switch body 60 placed near both sides of the hook 4, and when further latching, the contacts s a + s b 2 are pushed apart and the elastic force of the contacts s & 6 b is used to hold them. The contact pressure with the metal fitting 4 is maintained. FIGS. 3 and 3 are sectional views of the locked state of the lid opening/closing interlocking switch device according to the present invention, seen from the side and the front, in which the fastener 3 connects to the two contacts of the switch body 6 in the locked state. 5J It is shown that 5b is pushed apart and in contact.

のである。Effects of the Invention As described above, the present invention makes it possible to reliably realize the non-conducting state of the switch when the lid is opened by using the fastener as a short-circuit piece for the two contacts of the switch body, and furthermore, the two contacts of the switch body can be connected to the hook. By placing the shifter close to both sides, metal pieces will not inadvertently short-circuit the two contacts on the switch body as they become obstacles between the two contacts, and the two contacts on the switch body will be perpendicular to the insertion of the fastener. Since the switch is displaced in the direction, the contact pressure of the contact point does not change even with the overstroke required for locking the lid, and a stable contact state is maintained, thereby realizing a lid opening/closing interlocking switch with great practical effect.
