Description

[Detailed description of the invention] Industrial applications The present invention relates to an opening/closing lid device.

Conventional configurations and problems There have been many devices that have an opening/closing lid as a part of the equipment, and in particular, devices operate in conjunction with the opening/closing status of the lid in order to obtain information about the opening/closing status. More and more devices are equipped with a switch mechanism. A conventional opening/closing lid device having such a switch mechanism will be described below with reference to FIGS. 1 and 2. In the figure, 1 is an opening/closing lid;
1a is an opening/closing handle provided on this opening/closing lid 1, 1b is an engaging piece when closing the opening/closing lid 1, 2 is a rotating hinge portion of the opening/closing lid 1 having a rotating shaft 2a, and 3 is a pivotal support for the opening/closing M1. A microswitch provided on the base 4 side, 5 a panel, 6 the engagement piece 1
A rotary type C1 that can be freely engaged and detached from the shaft 6 with respect to the base 4.

is biased in the direction of engagement.

8 is a stopper. 9 is a lead wire connected to the microswitch 3.

Next, the operation of the conventional opening/closing lid device configured as described above will be explained. Fig. 1 shows the open state, and Fig. 2 shows the open state. 6 is engaged, and at the same time the microswitch 3 is engaged by the rotating hinge part 2.
is operated, and the recognition of the closed state is given as information by the operation of the microswitch 3. However, such a device requires a mechanism for operating the rotary mold 6 in the direction of releasing the engagement with the engagement piece 1b in order to open the lid 1 from the closed state shown in FIG. will increase. Further, the microswitch 3 is expensive, and furthermore, if the contacts of the microswitch 3 accidentally come into contact, erroneous information will be given even in the open state. Henceforth, F
In the conventional configuration, the mechanism is complicated and the cost is high, and there is a risk of giving incorrect information.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned drawbacks of the conventional art, and aims to provide an opening/closing lid device that is simple in construction, inexpensive, and provides accurate information.

Structure of the Invention In order to achieve the above object, the opening/closing lid device of the present invention includes an insulator in which a plurality of conductors are provided at intervals of J3 from each other on the fixed side or the opening/closing lid side, and a biasing member. The conductive ball, which is biased toward the insulator side, is placed on the opening/closing lid side or the fixed side, and when the opening/closing lid is closed, the ball fits between the plurality of conductive bodies to create electrical continuity. It is something.

DESCRIPTION OF EMBODIMENTS Hereinafter, one embodiment of the present invention will be explained with reference to the drawings (Figs. 3 to 6).
The explanation will be based on Figure).

In the drawings, the same reference numerals as those in the conventional example indicate the same members, and detailed description thereof will be omitted.

In the figure, 10 is an insulator attached to the base 4;
1 is a conductor provided in this insulator 10, and two conductors 1
An appropriate interval is provided between i and ii. Reference numeral 12 denotes a holder attached to the rotating hinge portion 2 of the opening/closing lid 1. A conductive ball 14 is biased in the direction of popping out by a spring 13 on this holder 12, and when the opening/closing lid 1 is closed, the ball 14 is the two conductors 1
It is located between the conductors 1i and ii to provide electrical continuity between the two conductors 1i and ii.

Reference numeral 15 denotes four parts formed on the insulator 10 so that the balls 14 fit therein when the lid 1 is open.

The opening/closing lid device and operation of this embodiment configured as described above will be explained.

In order to operate the cover 1 from FIG. 3 to FIG. 4 or from FIG. 4 to the state shown in FIG. 3, the ball 14 moves between the conductor 11.11 and the recess 15, In the state shown in FIG. 6 when the opening/closing lid 1 is closed, the ball 14 is positioned between the i8 bodies 11 and 11 to provide electrical conduction, and in other states, the conductor 11
．． 11 is in an insulated state.

As described above, according to this embodiment, the two conductors 11°11
This opening/closing lid device constitutes a switch by disposing the balls 14 at intervals and touching the two conductors 11. The opening/closing lid 1 can be opened and closed by installing the
The opening degree of the ball 14 can be easily set.
, ii, the opening/closing lid 1 is fixed. In the above embodiment, the IC insulating body 0 including the conductor 11 was provided on the base 4 side, and the ball 14 was provided on the opening/closing lid 1 side, but the reverse arrangement is also possible.

Effects of the Invention As described above, according to the present invention, by providing spaced conductors and balls in the opening/closing lid device, an inexpensive switch structure and opening/closing position regulation structure can be obtained, and erroneous information can be prevented. It is possible to demonstrate an excellent opening/closing M device that can prevent the risk of injury.
