As Fig. 4, shown in Figure 5, the substrate P CB assembly 20 of this microwave oven is made of motherboard 21 and at least one assisting base plate 30.Described motherboard 21 has only one side that printed circuit is arranged, and promptly in the one side relative with control panel 40 back sides printed circuit is arranged, and the one side that printed circuit is arranged is called circuit here and forms face 22, and forming on the face 22 at this circuit has printed circuit and various components and parts are housed.Power circuit, the circuit that produces electric oscillation, relay circuit, display circuit etc. are arranged on described motherboard 21.
On this motherboard 21, be provided with one or more and insert opening, all leave the certain intervals parallel arranged between wherein per two insertion openings 24.Extend on circuit formation face 22 always and insert the brace 25 that opening 24 is provided with a kind of printed circuit character, described brace 25 is electrically connected usefulness with following assisting base plate 30.
Be provided with terminal hole 27 inserting the position perforation shown in the upper diagram of opening 24, this terminal hole 27 connects motherboards 21, the place that terminal hole 27 makes progress between the insertion opening 24 of both sides a little.Form the connection base plate 28 that is provided with a kind of printed circuit character on every side of the terminal hole 27 on the face 22 at circuit.Symbol 29 is display devices among the figure.
Below assisting base plate 30 is described: described assisting base plate 30 is to have only one side that the single face substrate of printed circuit is arranged, because use this single face substrate lower than the cost that uses double-sided substrate.As shown in Figure 5, be that circuit forms face 31 below assisting base plate 30, be inverter circuit forms face 32 above.On this assisting base plate 30, be provided with the circuit of the paster that comprises miniature IC.
Both sides at assisting base plate 30 1 ends are provided with insertion section 34, and this insertion section 34 has and inserts 24 one-tenth tight insertion cooperations of perforate, and the interval of two insertion sections 34 is identical with the interval of inserting opening 24; And insertion section 34 can be inserted in the insertion opening 24 of both sides simultaneously.34 circuit forms the brace 35 that face 31 is provided with a kind of printed circuit character in the insertion section, and this brace 35 is corresponding with the number and the position that are provided with brace 25 near insertion opening 24, makes their realize being electrically connected by welding.
But,, be not the aspect 36 that must be formed with differing heights for mounted connector 37 on assisting base plate 30.Also can be contained in the plane that extends out from other parts, form on the face 32 thereby connector 37 is installed in above-mentioned inverter circuit.Necessary condition is, the difference in height between the terminal 38 of connector 37 and the insertion section 34 and terminal hole 27 are identical with the difference in height of inserting between the opening 34.
The terminal of connector 37 is inserted terminal hole 27 and welding, will be inserted into the insertion section of inserting in the opening 24 and the brace of opening simultaneously and also weld, so just assisting base plate 30 has been fixed on the motherboard 21.
In addition, if want on motherboard 21, to install several assisting base plates 30, as long as make several groups of terminal holes identical 27 again and insert opening 24 with assisting base plate 30 numbers at motherboard.
Baseplate assembly 20 is installed in the back of the control panel 40 of the controller that constitutes microwave oven.Be useful on the display window 43 that constitutes display part 42 on control panel 40, display device 29 comes out by display window 43 perspectives and shows various information thus.Certainly, on the counterpart of motherboard 21 and control panel 40, corresponding key accessory and button can be installed.
Effect to the baseplate assembly that constitutes microwave oven of the present invention is illustrated below.
The assembling of baseplate assembly 20 once is described earlier, at first will prepares motherboard 21 and assisting base plate 30, and on motherboard 21 and assisting base plate 30, load onto various components and parts with single face substrate formation.At this moment installation is not to have finished the installation of welding but pre-installment state before welding.
Afterwards assisting base plate 30 is installed on the motherboard 21, is about to each insertion section 34 and inserts in above-mentioned each insertion opening 24, in each terminal 38 insertion terminal holes 27 with connector 37, this state is exactly the pre-installment state of assisting base plate 30 on motherboard 21.At this moment owing to insert between opening 24 and the terminal hole 27 and have certain intervals, therefore can make the vertical pre-installment state of assisting base plate 30 maintenances and motherboard 21.
Carry out the operation of whole welding positions of disposable welding substrate assembly 20 afterwards.At this moment the brace 35 of insertion section 34 is realized being electrically connected by welding with the brace 25 that inserts opening 24, and terminal 38 is also realized being electrically connected by welding with the base plate 28 that is connected around the terminal hole 27.Certainly the welding by brace 35,25 makes them also realize physical connection simultaneously with terminal 38 and the welding that is connected base plate 28.
Particularly being inserted between the insertion section 34 of inserting in opening 24 and the terminal hole 27 and the connector 37 has certain height poor, and this can make the installment state of 21 of assisting base plate 30 and motherboards relatively firm.And can on motherboard 21, vertically install and use the assisting base plate 30 of required number according to design condition.
