Below, with reference to the accompanying drawings embodiments of the present invention are described.In addition, about part mutually mutually the same or impartial in each embodiment below, mark identical label in the drawings.
(the 1st embodiment)
1st embodiment of the present invention is described.
As shown in FIG. 1 to 3, the piezoelectric buzzer as electric device has housing 1, piezoelectric vibrating plate 2, portion of terminal 3 and 4, wire 5 and 6 and register (not shown).
Housing 1 is made up of insulative resin, and portion of terminal 3,4 is panelized into shape as insert.A part for portion of terminal 3,4 is embedded in housing 1, and a part is exposed from housing 1.This housing 1 roughly in rectangular shape, is formed with connector portion 11 in the end side of housing 1.Further, piezoelectric vibrating plate 2, portion of terminal 3 and 4 and register is had in the internal surface configurations of housing 1.
In addition, be in fact provided with case at this housing 1, piezoelectric vibrating plate 2, portion of terminal 3 and 4, wire 5 and 6 and register are covered by case, but in order to easy understand piezoelectric buzzer inside, in Fig. 1 ~ Fig. 3, do not illustrate case.
Piezoelectric vibrating plate 2 has: sheet metal 21, is made up of the thin plate of toroidal; Piezoelectric ceramic plate 22, is made up of the circular sheet having sintered silver paste, less than sheet metal 21 circle on surface and the back side.Further, sheet metal 21 and piezoelectric ceramic plate 22 are electrically connected by the conductive layer of the rear side of piezoelectric ceramic plate 22.
Wire 5 is for carrying out the electrical connection of the sheet metal 21 of portion of terminal 3 and piezoelectric vibrating plate 2, and wire 6 is for carrying out the electrical connection of the piezoelectric ceramic plate 22 of portion of terminal 4 and piezoelectric vibrating plate 2.
In addition, apply alternating voltage by portion of terminal 3,4 and wire 5,6 pairs of piezoelectric vibrating plates 2, make piezoelectric vibrating plate 2 pipe thus.
As shown in Figures 2 and 3, one end and the 3rd of the portion of terminal 3,4 of wire 5,6 are exposed plate portion 34,44 (being described in detail later) and are connected, and the other end is engaged in piezoelectric ceramic plate 22 or sheet metal 21 by such as soldering.
As shown in Fig. 1 ~ Fig. 7, portion of terminal 3,4 is made up of the sheet material of conductive metal, has the plate portion that buries underground 31,41 (special in Fig. 6, Fig. 7) being embedded in housing 1 and the 1st ~ 3rd protruding plate portion 32 ~ 34,42 ~ 44 of protruding from housing 1.
1st protruding plate portion 32,42 protrudes in the inner space in connector portion 11 (special in Fig. 6), is used as the splicing ear with external electrical connections.
2nd protruding plate portion 33,43, in the rear side of piezoelectric vibrating plate 2, protrudes (special in Fig. 4, Fig. 6), is used to the electrical connection with register in the inner space of housing 1.
3rd protruding plate portion 34,44 protrudes to the space outerpace side of housing 1 (special in Fig. 3, Fig. 4, Fig. 5), is used to the electrical connection with wire 5,6.
As shown in Fig. 2, Fig. 3, Fig. 5, be formed with two joint-cutting portions 35,45 in the front in the 3rd protruding plate portion 34,44.Further, under the state that the front of wire 5,6 is embedded this joint-cutting portion 35,45, by soldering or welding etc., wire 5,6 is bonded in the 3rd protruding plate portion 34,44.
At this, the heat when being bonded in the 3rd protruding plate portion 34,44 by wire 5,6, conducts from the position engaging wire 5,6 in the 3rd protruding plate portion 34,44 towards burying plate portion 31,41 underground.Below, by this heat conduction towards be called heat transfer direction.Further, the area in cross section vertical with heat transfer direction in the 3rd protruding plate portion 34,44 is called heat transfer area below.
Further, in the 3rd protruding plate portion 34,44, engaging the position of wire 5,6 and burying underground between plate portion 31,41 and be formed with through hole 36,46, reducing structure as the heat transfer area reducing heat transfer area.
That is, the heat transfer area at the position of through hole 36,46 is formed in the 3rd protruding plate portion 34,44, less than the heat transfer area not forming the position of through hole 36,46 in the 3rd protruding plate portion 34,44.
Like this, by arranging through hole 36,46, when wire 5,6 is bonded in the 3rd protruding plate portion 34,44, can suppress, from the position engaging wire 5,6 in the 3rd protruding plate portion 34,44 to the heat transfer burying plate portion 31,41 underground, thus can prevent the melting of housing 1.
(the 2nd embodiment)
2nd embodiment of the present invention is described.Below, only the part different from the 1st embodiment is described.
As shown in Figure 8, in the present embodiment, cancel through hole 36,46, the 3rd protruding plate portion 34 the position engaging wire 5 and bury underground between plate portion 31 and be formed with joint-cutting portion 37, this joint-cutting portion 37 reduces structure as the heat transfer area reducing heat transfer area.More particularly, two joint-cutting portions 37 are configured with in the position separated along heat transfer direction.
In addition, although not diagram, but be also formed with joint-cutting portion at the position engaging wire 6 (with reference to Fig. 1) in the 3rd protruding plate portion 44 (with reference to Fig. 1) with burying underground between plate portion 41 (with reference to Fig. 7), this joint-cutting portion reduces to construct as the heat transfer area reducing heat transfer area.
According to the present embodiment, when wire 5,6 is bonded in the 3rd protruding plate portion 34,44, can suppress, from the position engaging wire 5,6 in the 3rd protruding plate portion 34,44 to the heat transfer burying plate portion 31,41 underground, thus can prevent the melting of housing 1.
