Crystal unit attaching electronic equipment

摘要

(57) Abstract Objective Crystal unit and crystal yu which are installed in the electronic equipmentBetween the knit holding down component, by the fact that it lies between the circuit substrate,Expanding the effective space of the circuit substrate, miniaturization of the electronic equipmentAs forming it does, through the circuit substrate, crystal unit the pushingYou hold down by the fact that you obtain, mark to stabilization and crystal unit of powerGeneration is prevented. Constitution The crystal which is locked to circuit substrate 2 in soldered and the likeIn the fixed structure of unit 1, circuit substrate 2 the crystal uni-tsuto to lie between 1 and crystal unit holding down component 4, the crystalPossessing elasticity, the pushing it overpowers the destal vicinity of unit 1.
