The sensor body 3 is attached by two different mechanisms. Therefore, even if the wireless terminal 1 is repeatedly attached to and detached from the magnetic attachment surface M, the stress applied to the attachment member 2 at the time of attachment and detachment is applied to the engagement point between the hook portion 23 and the hook groove portion 31 and the screwing portion by the screw 25 Since it is dispersed, loosening of the mounting member 2 and falling off from the sensor body 3 are suppressed.

  Even if the force in the direction of the arrow shown in FIG. 6A is applied to the heat ray sensor 1, the upper end portion of the mounting member 2 and the sensor body 3 are joined by the engagement of the hook portion 23 and the hook groove portion 31. Therefore, the mounting member 2 is prevented from being distorted or falling off from the sensor body 3.

  Next, the case where the attachment member 2 is attached to the sensor body 3 in the opposite direction to the above will be described with reference to FIGS. In this case, the mounting member 2 is screwed to a predetermined mounting location with a screw (not shown) so that the magnet 21 is exposed to the outside. In the illustrated example, the attachment member 2 is screwed to the wall surface W by screws inserted from the magnet 21 side into the holes 26a and 27a and the holes 26b and 27b.

  In order to attach the sensor body 3 to the attachment member 2 fixed to the wall surface W, first, the alignment groove 24 of the attachment member 2 and the alignment groove 36 of the sensor body 3 are aligned with each other, whereby the hooking portion of the attachment member 2 is obtained. 23 and the hooking groove 31 of the sensor body 3 are arranged at positions where they can be engaged with each other. Next, the sensor main body 3 is moved downward from this state, and the hook groove 31 and the hook 23 are engaged by inserting the hook groove 31 into the gap 28b. Thereby, the metal plate 32 of the sensor body 3 is disposed at a position facing the lower end of the magnet 21 of the mounting member 2, and the magnet 21 and the metal plate 32 are joined to each other. In this way, the sensor body 3 is attached to the attachment member 2 by two different mechanisms of engagement between the hook portion 23 and the hook groove portion 31 and joining of the magnet 21 and the metal plate 32.

  As described above, according to the heat ray sensor 1 of the present embodiment, the sensor body 3 can be attached to the magnetic attachment surface M or the wall surface W via the attachment member 2.

Thus, the attachment member 2 can be firmly attached to the wireless terminal body 3.

  Further, since the mounting bracket 22 covers the lower surface of the magnet 21, the magnetic force at the lower end of the magnet 21 is enhanced. As a result, when the magnet 21 of the mounting member 2 and the metal plate 32 of the sensor body 3 are bonded to each other, the bonding between the magnet 21 and the metal plate 32 becomes strong, and the mounting member 2 is securely attached to the sensor body 3. be able to.

  Moreover, since the attachment member 2 also functions as a lid that covers the opening 34 of the sensor main body 3, it is possible to prevent the replacement member such as the battery 35 from dropping from the sensor main body 3 without providing a separate member.

  Further, since the recess 27 for receiving the screw head of the screw 25 is provided in the hole 27 of the magnet 21, when the screw 25 is inserted into the hole 27 from the magnet 21 side, the screw head of the screw 25 is the bonding surface of the magnet 21. Do not protrude from. Therefore, when the magnet 21 is joined to the magnetic attachment surface M or the metal plate 32, the screw head of the screw 25 does not get in the way, so the magnet 21 and the magnetic attachment surface M or the metal plate 32 are firmly joined.

  In addition, the radio | wireless terminal which concerns on this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, the wireless terminal main body is not limited to a heat ray sensor, and may be an illuminance sensor that detects light illuminance, for example.
