有効に生かしているとは限らない。[Prior Art] Constant temperature oven type crystal oscillators have been widely used in broadcasting equipment, control equipment, and the like. A drawback of crystal oscillators with a built-in thermostat is that they are large in size, making it difficult to downsize them. This is because the heat insulating material that surrounds the thermostatic chamber is made of a material that contains many layers of air between them, resulting in a large volume. The main insulation materials used are Styrofoam and synthetic cotton. When these heat insulating materials have an irregular external shape, methods have been used such as wrapping them around a constant temperature bath or forming the external shape in advance with a mold and fitting the constant temperature bath into this. However, winding the fibers or installing a constant temperature bath is inefficient and does not always make the most of a small space.

。Structure of the Present Invention> [Means for Solving the Problems] Accordingly, in the present invention, after the oscillator is assembled, the manufacturing method can be simplified by injecting the heat insulating material through a hole formed in the container. A hole in the container is made near the constant temperature bath so that the heat insulating material can be easily poured into the constant temperature bath.

A heater is wound around a crystal oscillator, a thermosensing element is attached to the crystal oscillator, and electronic components 3 constituting an electronic circuit including a constant temperature bath 2 and an oscillation circuit are fixed to a substrate 4. The substrate 4, thermostatic chamber 2, and electronic components 3 are covered by a container IO.

Thereafter, a heat insulating material 5 such as a foam heat insulating material or a resin heat insulating material is injected through the hole 1 provided in the container 310 to fill the space inside the container. 6 is a nozzle for injecting heat insulating material.

。Furthermore, if you do not want electronic components outside the thermostatic chamber to come into contact with the heat insulating material, you can cover the components or prepare a simple stopper wall. For example, 7 has a trimmer adjustment hole 8 formed in the upper part of the adjustment trimmer, and a frame 9 is provided to prevent the heat insulating material 5 from being injected. The hole 8 and frame 9 are provided as necessary.
