Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiment.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The attachment means for piezoelectricity selection piece and circuit board of the present embodiment as shown in figure 1, including：Select installed in piezoelectricity
Car pin 10 on faller gill 30 and the needle stand 20 on circuit board 40, car pin 10 are connected to piezoelectricity needle selection by conductive adhesive curing
On piece 30.
As shown in Fig. 2 car pin 10 includes：Weld part 11, insertion section 14 and formation limiting stand 13 therebetween, welding
Portion 11, insertion section 14 and limiting stand 13 are integrally formed, and make whole car needle construction firm, not pliable or fracture.Limiting stand
13 be used for limit car pin 10 be solidificated in piezoelectricity selection piece 30 protection plastic housing 33 when defined position.
As shown in figure 3, needle stand 20 includes：Pedestal 23 and in the cavity 25 of pedestal 23 for clamping the insertion section
14 spring pawl 21, all spring pawls 21 are evenly distributed in pedestal 23, the inwall of 21 one end tight fit connection pedestal 23 of all spring pawls,
The engaging nail of other end spring pawl extends to 23 bottom of pedestal and in the trend that draws close to pedestal axis, so as to clamp insertion section
