Detailed description of the invention
Fig. 1 shows the circuit board housing 1 for containment circuit board 2 (as shown in Figure 2), and the unit be wherein made up of circuit board housing 1 and circuit board 2 can be inserted into (as shown in Figure 3) in the main casing 3 of dust catcher.
Get back to Fig. 1, this circuit board housing 1 be designed to be made of plastics and have plane, continuous print wall 4, arranging at the edge of wall higher than the groove 5 of this wall 4, as referred to from Fig. 4, in this groove, inserting an annular seal 6.Arrange three fixtures 7 in the edge of circuit board housing 1, these fixtures have away from edge respectively to the stay hook 8 that wall 4 extends.
Determine the size of circuit board 2 and circuit board housing 1 like this, that is, as shown in Figure 2, by means of stay hook 8 this circuit board 2 is fixed in fixture 7 like this and (represents with arrow 9), that is, make this circuit board 2 by its first surface 10 close seal 6 in a contact fashion.Because the seal 6 round this circuit board housing 2 edge and arrange, obtained by this first surface 10, the seal 6 and wall 4 and circuit board housing 1 one fix limit and close inner chamber 11.
As referred to from the cross section in Fig. 4, this circuit board 2 covers wall 4 and is fixed in the stay hook 8 of fixture 7.The plane that this circuit board 2 is parallel to wall 4 extends and extends, between circuit board 2 and wall 4, wherein maintain distance 12.This distance 12 depends on the structure height of the first electronic component 13 with regard to its distance size and between 5 to 50mm, can be preferably about 10mm.This circuit board 2 has multiple electronic SMD components 13 as the first electronic component 13 of completing in surface mount at its first surface 10 and has multiple electronics THT element 15 as the second electronic component 15 completed in through hole is installed in its second face 14 contrary with first surface 10.This circuit board 2 is arranged in dust catcher like this, that is, this second face 14 be arranged at least partially suck air flow path in.Under the state hidden, namely, after circuit board 2 is fixed together with circuit board housing 1 by means of fixture 7 (represented by arrow 9 in fig. 2), as illustrated in fig. 4, SMD element 13 is arranged in inner chamber 11 and is also hidden by circuit board housing 1 thus moisture seal.
If containing moisture in the suction air that the motor 25 by dust catcher produces, so these SMD elements 13 can not produce with these moisture and contact, and this SMD element is therefore protected to prevent its damage, short circuit and/or break down due to moisture.Although these THT elements 15 do not carry out moisture protection by circuit board housing 1; but compared with SMD element 13 but more moisture resistance gas, thus when sucking air usually containing also not worrying the damage of the THT element 15 produced due to moisture, fault and/or destruction when moisture component.
In other words, these electronic components of the motor 25 for controlling dust catcher are distributed, that is, first surface 10 only arranges SMD element 13 and THT element 15 is only set on the second face 14.
In order to arrange the electrical contact of THT element 15 on the circuit board 2 and SMD element 13, arrange one or more edge connector 16 on the circuit board 2, these plugs have multiple electrical pickoff (not shown) respectively.This edge connector 16 be arranged on first surface 10 by the seal 6 of annular outside the part that limits, hide, and not hidden by circuit board housing 1 in the second embodiment illustrated in fig. 2.In the another kind of embodiment do not illustrated in the accompanying drawings, this edge connector 16 is positioned at the fringe region of circuit board housing 1 and is determined by the edge of circuit board housing like this with the meaning of former with regard to its profile, that is, the seal of annular is close to the housing of edge connector 16 and the sealing of anti-tideland.
In order to electrical contact, particularly be arranged on first surface 10 and the electrical contact of SMD element by circuit board housing 1 moisture seal, be arranged on the plug completed in surface mount, wire can be drawn by space or groove 17 from circuit board housing 1 by this plug.Groove 17 is set like this in the edge of this circuit board housing 1 and determines the size of this groove, that is, hide state under wire is between circuit board 2 and seal 6, thus also when draw wire moisture seal ground closed inner chamber 11.
In order to be fixed on dust catcher on by circuit board housing 1 and fixing circuit board 2 (as shown in Figure 3 or Figure 4) thereon, circuit board housing 1 arranges multiple lug boss 18, and these lug bosses extend out from the edge of circuit board housing 1.Multiple storing apparatus 19 is correspondingly set on dust catcher with these lug bosses 18, these lug bosses 18 can be inserted in these storing apparatus, and the circuit board housing 1 with circuit board 2 can be inserted in these storing apparatus thus.This storing apparatus 19 is designed specifically to guide rail for this reason, thus circuit board housing 1 is inserted in these guide rails 19 to form fit by means of these lug bosses 18 in relative both sides respectively.After being inserted in dust catcher by means of circuit board housing 1 by circuit board 2 (as represented by arrow 24), these THT elements 15 are arranged in the suction air flowing caused by motor 25 and the air flow path formed also is cooled thus.
As above-mentioned, circuit board 2 one side is fixed by fixture 7 by the outer peripheral form fit with circuit board housing 1, wherein impels circuit board 2 axial compression relative to circuit board housing 1 by means of stay hook 8 on the other hand.By the assembling in dust catcher as shown in Figure 3, realize circuit board 2 to be finally fixed on circuit board housing 1 by circuit board housing 1 is inserted in storing apparatus 19 together with circuit board 2.
Referring again to Fig. 1, circuit board housing 1 has the second chamber 20, this chamber is fully separated with inner chamber 11 by means of the chamber seal 21 with seal 6 one piece design, namely, at this circuit board 2 in the mode around contact near chamber seal 21 and seal 6 time, separate to this second chamber and inner chamber 11 moisture seal and wiper seal.In this cavity area of first surface 10, arrange pressure sensor 22 (see Fig. 3), this pressure sensor is in the inside of this second chamber 20 under the state hidden.
This second chamber 20 has the opening 23 implemented as fixing pipe box 23 in the side away from chamber seal 21.As long as to install (what such as suck air is positioned at the forefoot area of cleaner dust-collection room with regard to the mobile handling machinery) flexible pipe ended at in the second isolated region of chamber 20 at fixing pipe box 23 place, so just can by means of pressure sensor 22 at this area inner measuring pressure, and without the need to arranging pressure sensor 22 for this reason and herein.Because this second chamber 20 is sealed relative to surrounding by means of chamber seal 21, can in a straightforward manner by the circuit board 2 integrated for pressure sensor 22.
As achievement by proposed circuit board housing 1; provide on the one hand simple especially and low cost, can moisture resistance protection in the possibility of the inner SMD element 13 responsive especially for moisture of dust catcher; and provide a kind of possibility so on the other hand; namely; in addition with the simple mode integrated pressure sensor 22 of technology, and can touch or contact pressure sensor 22 in installing in independence.
