It is mounted so that it can move up and down somewhat.

Therefore, when the lid E is closed, the contact pin F is
The contact pin F enters between the terminal portions D1 and D2 of the terminal portion D1 and D2, and conducts the two terminal portions D1 and D2 via the contact pin F.

In addition, in the conventional example shown in FIG. 6, a push switch H is attached to the player cabinet A as a switch mechanism, and is opened and closed by the operation of a button H1. Part I is formed.

When the lid E is closed, the protrusion I presses the button H1 of the push switch H, opening the push switch H.

``Problems to be solved by the invention'' However, the above-mentioned lid opening/closing switch structures only have a switch function, and the locking mechanism for player cabinet A and lid E is provided separately, so it is difficult to assemble the lid. becomes more complex, reducing work efficiency,
Further, it has drawbacks such as not being suitable for space saving and cost reduction.

The present invention was developed to solve the above-mentioned drawbacks, and by integrating the switch mechanism and the lock mechanism, the container has a lock mechanism that simplifies the configuration and assembly and saves space. It is to provide a switch structure.

"Means for Solving Problems" The present invention consists of a container body, a lid that can be opened and closed with respect to the container body, a switch mechanism that detects opening and closing of the lid, a contact plate that constitutes this switch mechanism, and a lid that can be opened and closed with respect to the container body. A pair of terminal parts spaced apart so as to be short-circuited by the contact plate, a locking mechanism formed of an insulating material that locks the container body and the lid, a locking fixing part constituting this locking mechanism, and the locking fixing part. The contact plate and the locking fixing part are integrated and attached to the lid, and the container body has a pair of terminal parts and a movable locking part. It is integrated and fixed.

``Operation of the invention'' Therefore, when the lid is closed, the locking movable part of the locking mechanism is locked by the locking fixed part. Also,
The contact plate of the switch mechanism shorts a pair of terminals to detect that the lid is closed.

Next, when you manually operate the operating part of the locking movable part,
The locking movable part is disengaged from the locking fixed part, the lock is released, and the lid can be opened, and the contact plate is separated from the terminal part, so that the switch mechanism is in the open state.

"Configuration of Embodiments" The present invention will be described below based on embodiments shown in the drawings. Fig. 1 is an exploded perspective view of a switch structure with a locking mechanism for a container according to the present invention, Fig. 2 is a front view of the same in an assembled state, Fig. 3 is a cross-sectional view taken along the - line in Fig. 2, and Fig. 4 is an exploded perspective view. It is a perspective view when the same switch structure is applied to a disk player.

Reference numeral 3 denotes a switch mechanism for detecting opening/closing of the lid 2, and the switch mechanism 3 includes a contact plate 4 made of a conductive and springy member, and a contact plate 4 made of a conductive material as well. It is comprised of a pair of terminal parts 5a and 5b spaced apart so as to be short-circuited by the contact plate 4.

The contact plate 4 is formed with a mounting portion 4a bent into an L-shape at the upper end, and a contact portion 4b curved into a horizontal U-shape at the lower end. 4c
is a hole into which the mounting screw 6 is inserted.

Further, in the embodiment, a double-sided printed board 7 is used for the pair of terminal parts 5a, 5b, and a pair of copper foils printed on one side are used as the terminal parts 5a, 5b, and through holes are formed from the copper foils 5a, 5b. Lead wires 9a and 9b are connected to a pair of copper foils 8a and 8b formed on the other surface via the lead portions. Note that the lead wires 9a and 9b are connected to a lid opening/closing detection circuit (not shown).

10 is a locking mechanism formed of an insulating material that locks the container body 1 and the lid 2 in an open form;
This locking mechanism 10 is composed of a locking fixed part 11 and a locking movable part 12 that can be freely engaged with the locking fixed part 11.

The locking movable part 12 is placed horizontally with the shaft 1 in the center.
a rotating part 15 having an insertion hole 14 of 3, and a plate-like plate part 17 that is perpendicular to the axis of the rotating part 15 and connected upward, and has a window 16 formed in the center.
and a hook portion 2 formed by an inclined surface 18 and a downward stepped surface 19 formed at the tip of the plate portion 17.
0, and an operating section 21 protruding from the rotating section 15 in a direction perpendicular to the plate section 17.

Further, in the window portion 16 of the plate portion 17,
The double-sided printed board 7 of the switch mechanism 3 described above is mounted, and the double-sided printed board 7 is integrated with the plate portion 17 by a molding method such as insert or outsert.

On the other hand, the locking fixing part 11 has a horizontal part 22 and a vertical part 2.
3, and a hole 24 into which a mounting screw 6 is inserted is formed in the horizontal portion 22. Further, a window 25 is formed in the lower part of the vertical part 23, into which the contact part 4b of the contact plate 4 can freely enter, and a locking window 26 is formed in the upper part, into which the hook part 20 is removably locked. There is.

Then, the contact plate 4 is brought into contact with the back surfaces of the horizontal part 22 and the vertical part 23 of the locking fixing part 11, the contact part 4b is inserted into the window 25, and the horizontal part 4a of the contact plate 4 and the back surface of the vertical part 23 are brought into contact with each other. Hole 4c, 2 in the horizontal part 22
It is integrally fixed to the back surface of the lid 2 with the mounting screw 6 inserted in the lid 2. At this time, the tip of the contact portion 4b is made to slightly protrude from the front surface of the locking and fixing portion 11.

On the other hand, the locking movable part 12 is inserted into the insertion hole 1 of the rotating part 15.
The shaft 13 rotatably inserted into the container body 1 is attached to the container body 1 by fixing both ends of the shaft 13.
It is necessary that the free end of 1 protrudes from the side surface of the container body 1. Reference numeral 27 denotes a window hole formed in the upper surface of the container body 1 so that the locking fixed part 11 can engage with the locking movable part 12.

Although not shown in the drawings, the movable locking portion 12 is provided with a spring that urges the hook portion 20 toward the locking fixed portion 11 and a stopper that restricts its movement.

"Operation of the embodiment" Therefore, when the lid 2 is closed, the locking fixing part 1
The lower end of the vertical part 23 of 1 is the window hole 27 of the container body 1.
Since the hook part 20 of the locking movable part 12 slides on the inclined surface 18 of the hook part 20 through the locking movable part 12, the hook part 20 uses the shaft 13 as a fulcrum and retreats against the elastic force of the spring, and then moves back to the locking fixed part 11. When it reaches the locking window 26, the hook part 2
0 is restored and the stepped portion 19 is locked to the locking window 26,
The container body 1 and the lid 2 are locked so as not to be opened. On the other hand, since the contact portion 4b of the contact plate 4 contacts the terminal portions 5a, 5b of the double-sided printed board 7 provided on the movable locking portion 12, both terminal portions 5a, 5
b is short-circuited by the contact plate 4, and both lead wires 9a and 9b are brought into conduction.

Next, when opening the lid 2, when the operation part 21 of the locking movable part 12 extending outward from the container body 1 is pressed from below, the hook part 20 is opened with the shaft 13 as a fulcrum.
is separated from the locking window 26, the lock is released, and the lid can be opened. Further, when the operating part 21 is pressed, the pair of terminal parts 5a and 5b separate from the contact part 4b of the contact plate 4, so the lead wire 9
a and 9b are in an open state (non-conducting state).

In addition, the contact plate 4 and the terminal parts 5a, 5b
If you take measures against contact failure by applying gold plating, etc., it will become a reliable switch mechanism.

Further, in the above embodiment, a disk player was described as the container body 1, but the present invention is not limited to this, and is also effective for products in which the switch mechanism 3 detects the opening/closing state of the lid 2.

Further, although the copper foil portions of the double-sided printed circuit board 7 are used for the terminal portions 5a and 5b, it is of course possible to use a conductive member such as opposing leaf springs or wire rods.

"Effects of the Invention" As mentioned above, the present invention includes a container body 1, a lid 2 that can be opened and closed with respect to the container body 1, a switch mechanism 3 that detects the opening and closing of the lid 2, and a switch mechanism 3. a contact plate 4 and a pair of terminal parts 5 spaced apart so as to be short-circuited by the contact plate 4;
