(57) [abstract] (with revision) [Problem] An infrared sensor mounted on a printed circuit board
Covered with Fresnel lens to avoid wind effects. However, since the terminal portion of the infrared sensor is exposed, there is a risk of being affected by the wind from here and causing a malfunction. A terminal section of an infrared sensor fixed on a wiring of a printed circuit board by solder is mounted so as to be covered by a mask fixing section.

従来の球面フレネルレンズのプリント基板への取り付けは、図３に示すごとく 球面フレネルレンズの台座部３２にプリント基板への取り付け用爪３３を付け、 又プリント基板に取り付け用の穴３６を設け、これらを勘合させることで固定取 り付けを行った。 As shown in FIG. 3, a conventional spherical Fresnel lens is mounted on a printed circuit board by attaching a mounting claw 33 to the printed circuit board on the pedestal portion 32 of the spherical Fresnel lens and by providing a mounting hole 36 on the printed circuit board. The fixed mounting was performed by fitting them.

従来のフレネルレンズのプリント基板への装着は、赤外線センサの入光部はフ レネルレンズで覆い、周囲の風の影響等にする誤動作を防止する。しかし、図４ に示すごとく、赤外線センサは、入光部はシールされ封止されているので風の影 響は比較的受けにくいが、プリント基板に取り付け接続する電力供給及び信号出 力を行う端子４７は、受光エレメント４１の近くまで入っている。よって、端子 ４７は周囲の風の影響での温度変化を敏感に受光エレメントの近くまで取り込む 。これにより、受光エレメントが温度変化をし、誤動作をするという問題点があ った。 When a conventional Fresnel lens is mounted on a printed circuit board, the light-entering portion of the infrared sensor is covered with a Fresnel lens to prevent malfunction due to the influence of the surrounding wind. However, as shown in Fig. 4, the infrared sensor is relatively insensitive to wind because the light-entering part is sealed and sealed, but it is a terminal that is attached to a printed circuit board for power supply and signal output. 47 is close to the light receiving element 41. Therefore, the terminal 47 takes in the temperature change under the influence of the surrounding wind sensitively to the vicinity of the light receiving element. As a result, there has been a problem that the light receiving element changes its temperature and malfunctions.

図１に示すごとくフレネルレンズ部１１及び台座部１２とプリント基板配線上 で電気的接続する半田部１８を覆う取り付けマスク固定部１６において、プリン ト基板１４を挟み込むように取り付け穴１５を介し、取り付け爪１７により台座 部１２とマスク固定部１６を固定取り付けする。このように、赤外線センサ１３ のエネルギー入射部とプリント基板の配線上で電気的接続する半田部１８をフレ ネルレンズとマスク固定部で覆い固定することにより周囲の風の影響を受けにく くなり、誤動作を低減できる。 As shown in FIG. 1, in the mounting mask fixing portion 16 covering the solder portion 18 electrically connected to the Fresnel lens portion 11 and the pedestal portion 12 on the printed circuit board, the mounting is performed through the mounting hole 15 so as to sandwich the print substrate 14. The pedestal portion 12 and the mask fixing portion 16 are fixedly attached by claws 17. In this manner, the energy incident portion of the infrared sensor 13 and the solder portion 18 for electrical connection on the wiring of the printed circuit board are covered and fixed by the Fresnel lens and the mask fixing portion, so that it is less affected by the surrounding wind. Malfunctions can be reduced.

図１に示すごとく、フレネルレンズ部１１と台座部１２からなるエネルギー集 光具と固定爪１７付のマスク固定部１６により、プリント基板１４に実装された 赤外線センサ１３とプリント基板の配線上で電気的接続をする半田部１８と取付 穴１５を介し、挟み込み覆う。又、図２に示すごとく、台座部２２に固定爪２３ を付けた場合では、マスク固定部２７に固定爪２３を勘合させる固定穴２８を設 け集光具とマスク固定部を固定し覆う。 As shown in FIG. 1, an energy collector including a Fresnel lens unit 11 and a pedestal unit 12 and a mask fixing unit 16 with fixing claws 17 electrically connect the infrared sensor 13 mounted on the printed circuit board 14 with the wiring of the printed circuit board. It is sandwiched and covered via the solder part 18 and the mounting hole 15 for making a proper connection. As shown in FIG. 2, when the fixing claw 23 is attached to the pedestal portion 22, a fixing hole 28 for fitting the fixing claw 23 is provided in the mask fixing portion 27 to fix and cover the light collector and the mask fixing portion.
