THERMOSTATICALLY CONTROLLED QUARTZ GENERATOR

摘要

The present invention relates to a quartz generator that comprises an outer housing (1), a plate (2) as well as an inner housing (6) at the bottom of which the resonator is placed in its own housing (9). The inner housing (6) is made in the shape of an open box of a highly thermo-conductive material and has its bottom resting tightly against one side of the central part (3) of the plate (2). All the thermostatically controlled elements of the generator are mounted on the central part (3) of the plate (2), wherein said central part is separated from the peripheral part by slots (4) extending through the thickness of the plate. The central part is linked to the peripheral part by narrow bridges (5) which are located between the ends of said slots (4). Heating members (10) and a main temperature detector (11) are mounted on the side walls of the inner housing (6), wherein said housing also includes highly thermo-conductive rods (8) that extend through the plate (2) in its central part (3) in the vicinity of each of the bridges (5). The open side of the box (6) is closed with a thin lid (12) of copper so as to define a thermal insulation gap relative to the housing of the quartz resonator (9). A copper lid (13) is attached at the ends of the thermo-conductive rods (8) protruding above the opposite surface of the plate (2) so as to define a thermal insulation gap relative to the thermostatically controlled elements which are mounted on this side of the plate (2). The thermal regulator is realised as a bridge circuit and includes an additional thermo-sensitive arm having an additional temperature detector (15) mounted on the peripheral part of the plate (2).
