Problems solved by technology

[0009] However, since the erected printed circuit board 20 is supported on the second base printed circuit board 10 only by the joining force by solder in addition to the fitting holding force by the fitting groove 11, and the amount of solder used for connection increases. is limited, so the connection strength is not sufficient, and there are many cases where the connection part with the solder is peeled off and cannot function as an oscillator.

Abstract

There provide a highly stable piezoelectric oscillator, improving reliability by increasing holding stability when a printed board supporting a piezoelectric vibrator is joined onto a base printed board in a standing state. The highly stable piezoelectric oscillator includes a heat-generating component 30; an erected printed circuit board 20 ; a piezoelectric vibrator 40 and an oscillation circuit component. Connection pads 12,13 are arranged opposite on a substrate surface along both opposite edges of the engagement slit, and a semiarcuate side through hole 14 is bored in an engagement slit internal wall corresponding to each connection pad; and lead pads 22 are arranged on both surfaces of the engaged end part of the printed board 20 in opposition position relation with the connection pads, and the connection pads having side through holes are soldered and connected to the lead pads of the engagement end part one to one.

Description

technical field [0001] The present invention relates to a piezoelectric oscillator used as a frequency control device, and more particularly to an improvement in a highly stable piezoelectric oscillator having a structure in which a heater is used to heat a piezoelectric vibrator and a temperature control circuit is used to control the temperature of the heater. Background technique [0002] As a frequency control device for mobile communication equipment or transmission communication equipment, that is, a piezoelectric oscillator such as a quartz oscillator, there is known a constant temperature bath type piezoelectric oscillator, which uses a built-in heater and a temperature control circuit. By heating the piezoelectric vibrator and controlling its temperature, it is possible to output a highly stable frequency without being affected by external temperature changes. [0003] Furthermore, in recent years, in these fields, since various devices are required to be small, lig...
