no. 1 approach

[0036] refer to figure 1 A pyroelectric infrared detection device 100 according to the first embodiment of the present invention includes a pyroelectric element 10 , a mounting substrate 20 on which the pyroelectric element 10 is mounted, a base 70 for accommodating the pyroelectric element 10 and the mounting substrate 20 , and a package 90 .

[0037] Such as Figure 1 to Figure 3 As shown, the thermoelectric element 10 of this embodiment is a dual-type element, and includes: a rectangular thermoelectric plate 11 made of a thermoelectric material; an upper electrode 12 formed on the upper surface 11u of the pyroelectric plate 11; and Two lower electrodes (element-side electrodes) 13 and 14 are formed on the lower surface 111 of the pyroelectric body plate 11 . The lower electrodes 13 and 14 each have a square-shaped conductive pattern, and cover the left half and most of the left half of the lower surface 111 . The upper electrode 12 has two square conductive patterns corre...

no. 2 approach

[0053] The pyroelectric infrared detection device of the second embodiment of the present invention is a modified example of the pyroelectric infrared detection device 100 of the above-mentioned first embodiment, and only the differences from the first embodiment will be described below with reference to the drawings.

[0054] Such as Figure 8 to Figure 10 As shown, the pyroelectric infrared detection device of this embodiment includes a mounting substrate 20a. This mounting substrate 20a is identical to the mounting substrate 20 of the first embodiment (see Figure 8 and Figure 9 ) are roughly the same.

[0055] Specifically, the through hole 51 is formed in the corresponding region 50 which is a region corresponding to the thermoelectric element 10 in the mounting substrate 20 a. In addition, the upper electrodes 23 and 24 are also located in the corresponding region 50 . Furthermore, not one but two (ie, plural) through-holes 51 are provided, and the beam portion 52 i...

no. 3 approach

[0061] refer to Figure 12 to Figure 14 The pyroelectric infrared detection device 100c of the third embodiment of the present invention is a further modified example of the pyroelectric infrared detection device of the second embodiment described above. Therefore, only the differences between the above-described embodiment and this embodiment will be described below with reference to the drawings.

[0062] Such as Figure 12 to Figure 14 As shown, in this embodiment, a plurality of thermoelectric elements 10c are mounted on one mounting substrate 20c.

[0063] From Figure 12 It can be seen that the mounting substrate 20c has a peripheral portion 22p and a central portion 22c, and has a shape in which the central portion 22c protrudes upward from the peripheral portion 22p. Specifically, the mounting substrate 20c has a hemispherical shape in which a central portion protrudes in a convex shape.

[0064] From Figure 12 to Figure 14 It can be seen that five thermoelectric...

Abstract

While conductive adhesives 60 are provided between element electrodes of a pyroelectric element 10 and board electrodes of an installation board 20, the conductive adhesives 60 are hardened to connect between the element electrodes of the pyroelectric element 10 and the board electrodes of the installation board 20. The conductive adhesives 60 include epoxy resin and, after hardened, have 4 B to 7 H, both inclusive, of pencil hardness as their hardness on JIS K 5600-5-4 (ISO 15184) standard basis. If the pyroelectric element 10 is broken down, the hardened conductive adhesives 60 are impacted or are cut by using a cutter to take off the pyroelectric element 10 from the installation board 20.

Description

technical field [0001] The present invention relates to a pyroelectric infrared detection device equipped with a temperature detecting element (pyroelectric element) having a pyroelectric effect, and a method for replacing the pyroelectric element in the pyroelectric infrared detection device. Background technique [0002] For example, Patent Document 1 discloses a pyroelectric infrared detection device including: a housing having two pyroelectric elements inside; and two lenses that condense infrared rays onto the two pyroelectric elements. [0003] Patent Document 2 discloses a pyroelectric infrared detection device having a structure in which a pyroelectric element is mounted on a substrate. In the pyroelectric infrared detection device of Patent Document 2, the electrodes of the pyroelectric element and the electrodes of the substrate are electrically connected by a cured conductive adhesive. The hardness of the cured conductive adhesive is about 5B to 6B in pencil hard...
