However, such a waterproof device has the following technical problems caused by arranging a plurality of bottomed concave portions in such a direction that the opening is on the top and the bottom is on the bottom.
That is, liquid or solid foreign matter is mixed in the recessed portion during use of the waterproof device.

More specifically, in such a waterproof type device, the recessed portion is installed on the back side of the waterproof housing from the viewpoint of preventing the setting member from being accidentally or mischievously prevented from falling out, and further, the appearance of the device itself is not impaired. In particular, in a waterproof device that receives power supply from a built-in battery, in addition to turning on / off the power of the waterproof device, for example, when providing a wireless communication function in the waterproof device, the communication frequency channel is selected and set. Due to the necessity of the function, it is required to provide at least a plurality of recessed portions on the upper surface of the waterproof housing.
At this time, although the opening of the recessed portion into which the setting member is inserted is closed by the setting member itself or the support member that supports the setting member, the other recessed portion has the opening left open, and is inside the recessed portion. There is a high possibility that liquid or solid foreign matter will enter.
Moreover, since the electrical circuit setting of the waterproof device is generally kept for a long time once set, the liquid or solid foreign matter mixed in the recessed portion is left for a long time. There are many cases.

In particular, when the waterproof casing is made of resin, moisture accumulates in the recessed portion for a long period of time, which causes the waterproof casing itself to elute, impairing the waterproofness of the device and affecting the field conditions. The setting of the electric circuit may be canceled.

  As a waterproof device, a wireless waterproof sensor will be described as an example with reference to the drawings.

In FIG. 1, the waterproof sensor 10 of the present embodiment includes a circuit board 24 between a waterproof casing body 18 provided with a temperature detector 16 facing downward (right side in the figure) in a ceiling-mounted state. The waterproof casing cover 20 that forms the sealed hollow portion 120 to be installed and the outer cover 12 into which the waterproof casing cover 20 can be fitted are provided. The waterproof casing cover 20 opens upward and is formed on the upper surface 122. The outer cover 12 has a peripheral wall 124 that surrounds a first setting hole 30 and a second setting hole 32, which will be described later. The waterproof casing cover 20 is fitted in such a manner that the peripheral wall 130 extends and the outer peripheral surface of the peripheral wall 124 of the waterproof casing cover 20 faces the inner peripheral surface of the peripheral wall 130 of the outer cover 12. The waterproof casing main body 18 and the waterproof casing cover 20 are fixed via a seal ring 22, thereby ensuring waterproofness.
The waterproof sensor 10 is usually attached so that the openings of the waterproof housing cover 20 and the outer cover 12 face up, for example, on the ceiling, so as to close the openings.

  As shown in FIGS. 2 and 3, a temperature detection unit 16 using a thermistor or the like is disposed inside a guard cover 14 formed at the lower part of the outer cover 12 so as to receive a hot air current due to a fire. An LED 15 that operates as a warning indicator lamp is provided at a lower position of 12 so that its operating state can be visually recognized from the floor side in the ceiling installation state.

  The waterproof casing body 18, the waterproof casing cover 20, and the outer cover 12 constituting the casing of the waterproof sensor 10 are preferably made of integrally molded resin, and in particular, the waterproof casing cover 20 is made of transparent resin. By doing so, it is possible to omit the clamping member 158 as the vertical direction positioning of the raised portion 150 and the setting member 25 described later.

    As shown in FIG. 1, the waterproof sensor 10 of the present embodiment has a first setting hole 30 and a second setting hole on the upper surface 122 of the waterproof housing 20 that is located on the ceiling surface side of the outer cover 12. 32 are formed at a predetermined interval from each other. This interval does not affect the setting member 35 inserted into the second setting hole 32 with respect to the first magnetic detection element 25 described later, and does not affect the first setting hole 30 with respect to the second magnetic detection element 26. It is set from the viewpoint that the setting member 35 to be inserted does not influence. Each of the first setting hole 30 and the second setting hole 32 forms a bottomed recessed portion that protrudes into the inside of the waterproof housing cover 20 from an opening provided on the upper surface 122 of the waterproof housing cover 20.

FIG. 4 clearly shows the assembled state of the two batteries 42 housed on the waterproof housing cover 20 side provided in the waterproof sensor 10. In the present embodiment, the first setting hole 30 and the second setting hole 32 into which the setting magnet 36 (see FIG. 5) of the setting member 35 is inserted are arranged using a space between the two batteries 42. Thus, even if the battery 42 is housed, a plurality of setting holes for inserting the setting member 35 can be formed on the back surface side.
As shown in FIG. 5, the setting of the electric circuit stored in the waterproof housing is performed by inserting a setting member 35 described later into either the first setting hole 30 or the second setting hole 32. be able to.

The setting member 35 uses a thin cylindrical rod-shaped setting magnet 36 in the present embodiment, and correspondingly, the bottom of the first setting hole 30 and the second setting hole 32 on the circuit board 24. The first magnetic detection element 25 and the second magnetic detection element 26 are arranged as setting member detection portions at positions facing each other. As these magnetic detection elements, for example, Hall elements can be used. The Hall element can be equivalently expressed by a resistance bridge circuit. When the magnetism is approached, the balance of the resistance bridge circuit is lost, and a magnetic detection signal corresponding to the strength of the magnetism is output. In addition, the Hall element includes a unipolar detection type that detects only the S pole or the N pole, and a bipolar detection type that detects both the S pole and the N pole. Also good. Note that magnetism may be detected using a reed switch or the like instead of the Hall element.
In this case, the insertion depth of the setting magnet 36 into the first setting hole 30 or the second setting hole 32 is determined by inserting the setting magnet 36 into the first setting hole 30 or the second setting hole 32. The interval D2 (see FIG. 9) is set so that the magnetic detection element 25 and the second magnetic detection element 26 can detect the magnetism of the setting magnet 36.
Referring to the setting member 35, the setting member 35 uses a thin cylindrical rod-shaped setting magnet 36 in the present embodiment, and its upper end is attached to a rubber cap 38.

More specifically, as shown in FIGS. 6 to 8, the rubber cap 38 has a flat portion 140 that is wide enough to cover the openings of the first setting hole 30 and the second setting hole 32, and is flat. The portion 140 is provided with a support portion 142 that supports the upper end portion of the setting magnet 36, and other than the setting hole (either the first setting hole 30 or the second setting hole 32) into which the setting magnet 36 is inserted. A press-fit portion 144 is provided to be spaced from the support portion 142 by a predetermined distance so as to be press-fit into the opening of the setting hole.
The support portion 142 includes a fitting hole 146 that fits into the upper end of the setting magnet 36, and when the setting magnet 36 is inserted into the first setting hole 30 or the second setting hole 32, the first setting hole 30 or By having an outer shape that can be press-fitted into the opening of the second setting hole 32, a drop prevention means is formed.

  On the other hand, the press-fit portion 144 has the same shape as the support portion 142, has an outer shape that can be press-fitted into the opening of the first setting hole 30 or the second setting hole 32, and the setting magnet 36 is inserted into the first setting hole 30. Alternatively, when inserting into one of the openings of the second setting hole 32, the support portion 142 can be press-fitted simultaneously into the first setting hole 30 where the setting magnet 36 is not inserted or the other opening of the second setting hole 32. Is spaced a predetermined distance D1.

As shown in FIG. 9, the first setting hole 30 and the second setting hole 32 are both the same shape, and are tapered frustoconical holes, and accordingly, the support portion 142 and the press-fit portion. 144 also has a truncated cone shape. By setting the first setting hole 30 and the second setting hole 32 to have the same shape, the press-fit portion 144 is set to the other regardless of whether the setting magnet 36 is inserted into the first setting hole 30 or the second setting hole 32. It is possible to press fit into the opening of the hole.
The rubber cap 38 is a fixed material having a thickness, for example, a substantially rectangular parallelepiped shape, and is easy to insert when the user inserts the small setting magnet 36 into either the first setting hole 30 or the second setting hole 32. In addition, it also plays a role of picking that is large enough to be picked by a human finger.

On the surface opposite to the flat portion 140 of the rubber cap 38, a raised portion 150 is provided at a position corresponding to the setting magnet 36. Usually, the rubber cap 38 and the waterproof housing cover 20 are opaque. When the rubber cap 38 is picked and the setting magnet 36 is inserted into either the first setting hole 30 or the second setting hole 32 from above or after the insertion, the setting magnet 36 is located on either side of the rubber cap 38. Therefore, the setting magnet 36 functions as a position display mark. In this respect, the raised portion 150 may be a seal or the like that is simply attached to the opposite surface, or may be a recessed portion instead of the raised portion.
An air vent hole (not shown) having a small diameter is formed in the upper portion of the fitting hole 146, and when the setting magnet 36 is fitted into the fitting hole 146, the air inside is passed to the outside through the air vent hole. By letting it escape, the compressed air remains in the fitting hole 146 and becomes an insertion resistance, and the setting magnet 36 is prevented from being pushed out by the repulsive force.

Further, as shown in FIG. 10, a string member 40 as a connecting member is tied to the rubber cap 38, and correspondingly, in the flat portion 140 of the rubber cap 38, between the support portion 142 and the press-fit portion 144. Is provided with a recess 152 so that the knot or the like of the string member 40 can be embedded therein. Accordingly, when the setting magnet 36 is inserted into either the first setting hole 30 or the second setting hole 32 from above, the opening is closed by contacting the flat surface portion 140 with the upper surface 122 of the waterproof housing cover 20. However, the string member 40 is not disturbed. The size of the recess 152 may be determined from such a viewpoint. On the other hand, a reinforcing convex portion 154 is provided at a position corresponding to the concave portion 152 on the opposite side of the flat surface portion 140 to reinforce the decrease in strength of the rubber cap 38 due to the provision of the concave portion 152 and to increase the overall thickness. The moldability is improved by making it as uniform as possible.
As shown in FIG. 10, the other end of the string member 40 is locked to the housing side so that the setting member 35 does not fall off.

  More specifically, as shown in FIG. 11, a hook member 155 extending downward to hook the string member 40 is provided on the inner peripheral surface of the peripheral wall 124 of the waterproof housing cover 20, and an opening is provided below the hook member 155. On the other hand, as shown in FIG. 12, a protruding member 157 protruding upward is provided at a predetermined position in the radial direction of the bottom surface 126 of the outer cover 12, and the waterproof housing cover 20 is connected to the outer cover 12. The upper portion of the outer surface 158 of the protruding member 157 contacts the lower end of the hook member 155 through the opening 156, so that the string member 40 is prevented from being pulled out. The circumferential position on the inner peripheral surface of the peripheral wall 124 where the hook member 155 is provided may be determined as appropriate.

  Further, as shown in FIGS. 5 and 10, a connection member holding portion 160 for holding the string member 40 is provided between the first setting hole 30 or the second setting hole 32 and the hook member 155, and the connection member The string member 40 is held by the holding unit 160. More specifically, the connection member holding portion 160 is provided at the insertion position of the battery 42 and includes an incision 164 that extends upward and opens downward so that the opening 162 is normally closed, and the string member 40 is opened from above. The cord member 40 is securely clamped by the connecting member holding portion 160 by being pushed into the notch 161 via 162. Note that the connection member holding portion 160 is preferably integrally formed with the waterproof housing cover 20.

    As the string member 40, for example, a string-shaped molded product such as a flexible synthetic resin is used. In FIG. 5, the string member of the setting member 35 is omitted. Further, in the example of FIG. 10, the string member is connected between the rubber cap 38 and the hook member 155 to prevent the drop. However, instead of connecting the string member, the string member and the rubber cap are formed when the rubber cap is formed. May be formed integrally, and the casing and the string member 40 may be formed integrally.

  As shown in FIGS. 5 and 9, the rubber cap 38 is fixed to the upper surface 122 of the waterproof housing cover 20 at a predetermined interval in the direction connecting the first setting hole 30 and the second setting hole 32. A pair of clamp claws 158 for holding are provided in a direction extending upward from the upper surface 122, and the pair of clamp claws 158 form a means for preventing the setting member 35 from coming off. Further, a protruding piece 160 that protrudes by a predetermined amount in the direction toward each other is provided at the upper end of each of the pair of clamp claws 158, and the rubber cap 38 is snapped between the pair of clamp claws 158 by the protruding piece 160. Then, the setting member 35 is positioned in the vertical direction. That is, when the user picks the rubber cap 38 and inserts the setting magnet 36 into either the first setting hole 30 or the second setting hole 32 from above, how much the setting magnet 36 is inserted into the selected setting hole. This point is clarified by such a snap fit because it is difficult to determine whether it should be done. Of course, it is also for holding the setting member 35 reliably. Note that the pair of clamp claws 158 may be integrally formed in the case when the waterproof case is made of resin.

  FIG. 13 shows a modification of the setting member 35. In this example, the setting magnet 36 is press-fitted and fixed in a hole (not shown) provided in the flat portion 140 of the rubber cap 38. Unlike FIG. 9, the setting magnet 36 is set by the support portion 142 of the setting member 35. The setting hole into which the member 35 is inserted is not press-fitted. According to this example, the first setting hole 30 and the second setting hole are inserted by the flat portion 140 of the rubber cap 38 by inserting the setting magnet 36 into the selected setting hole (the first setting hole 30 in the figure). Each of the openings 32 is closed, and the press-fit portion 144 is press-fitted into the other setting hole (second setting hole 32 in the figure), thereby preventing the setting magnet 36 from coming off.

  FIG. 14 shows a further modification of the setting member 35. In this example, the first setting hole 30 and the second setting hole 32 are respectively inserted into the selected setting hole (first setting hole 30 in the figure) by the flat portion 140 of the rubber cap 38 by inserting the setting magnet 36. However, the setting magnet 36 is not prevented from coming off by press-fitting the press-fitting portion 144 into the other setting hole (second setting hole 32 in the figure). As an alternative to the press-fit portion 144, the rubber cap 38 is pressed against the upper surface 122 of the waterproof housing cover 20 via the flat portion 140 by a pair of clamp members 158, thereby preventing the setting magnet 36 from coming off. doing.

FIG. 15 shows a further modification of the setting member 35. In this example, the first setting hole 30 and the second setting hole 32 are respectively inserted into the selected setting hole (first setting hole 30 in the figure) by the flat portion 140 of the rubber cap 38 by inserting the setting magnet 36. As shown in FIG. 13, the pair of clamp members 158 does not prevent the setting magnet 36 from being removed, but instead of such a pair of clamp members 158, as shown in FIG. By utilizing the support portion 142 that supports the setting magnet 36 as a press-fit portion, the setting magnet 36 is prevented from coming off.
As another modification, the upper surface 122 of the waterproof casing is provided with a groove (not shown) having a rectangular cross section, the first setting hole 30 and the second setting hole 32 are provided on the bottom surface of the groove, and rubber is provided. By allowing the cap 38 to be press-fitted into the groove, a drop prevention means may be formed.

This frequency channel will be described as channel A and channel B in the following description.

The memory 78 stores a transmission source ID 94. In the waterproof sensor 10 of this embodiment, when an event such as a fire is detected, a telegram signal (hereinafter referred to as a telegram) having a predetermined telegram format is transmitted. The message format consists of a phase correction signal, sender ID, message contents, and error check code. The receiver determines the meaning of the message contents after judging whether it matches the registered note ID by looking at the sender ID. Judgment is made to process.
The sensor unit 80 is provided with a temperature detection unit 16, and for example, a thermistor is used as the temperature detection unit 16 and outputs a temperature detection signal to the processor 72. The display unit 82 is provided with an LED 15 that functions as an alarm indicator lamp. The LED 15 is driven to display at the same time as the notification display and also during the test communication from the wireless communication unit 74.
The setting member detection unit 84 is provided with the first magnetic detection element 25 and the second magnetic detection element 26 as described above.
The test operation detection unit 86 is provided with a test operation detection magnetic detection element 96. When a test magnet is approached from the outside for a communication test of the waterproof sensor 10, the test operation detection magnetic detection element 96 detects the magnetism and outputs a magnetic detection signal to the processor 72, for example, a communication test. The test operation is performed.
The processor 72 is provided with a channel setting unit 100 and a sensor processing unit 102 as functions realized by executing a program.
In the channel setting unit 100, the first magnetic detection element 25 outputs a magnetic detection signal when the setting magnet 36 of the setting member 35 is inserted into the first setting hole 30, and the channel setting unit 100 receives this signal. The channel A in the wireless communication unit 74 is set to a selected state.
On the other hand, the second magnetic detection element 26 outputs a magnetic detection signal when the setting magnet 36 of the setting member 35 is inserted into the second setting hole 32, and in response to this, the channel setting unit 100 performs wireless communication. The channel B in the unit 74 is set to a selected state.

The sensor processing unit 102 reads the temperature detection signal output from the temperature detection unit 16 of the sensor unit 80 and compares it with a predetermined threshold value. When the detected temperature exceeds the predetermined threshold value or the rate of change of the detected temperature Is determined to be a fire when a predetermined threshold value is exceeded, a message including a fire event is transmitted from the wireless communication unit 74 to the receiver side via the antenna 76, and a fire alarm is issued on the receiver side.
In addition to the fire event, the sensor processing unit 102 detects the occurrence of an event including recovery, battery exhaustion, failure, and periodic notification, and performs transmission processing.
