Detailed Description

Referring to fig. 1~3, the present embodiment provides a hemispherical resonator gyro base, which includes a base body 1 and a terminal 2, and a conductive layer 3 is disposed at a capacitor end of the base body 1.

In order to reduce manufacturing cost, preferably directly use current base body, terminal 2 can directly assemble in the signal of telecommunication connecting hole in base body 1, and the signal of telecommunication connecting hole is passed and is contacted with conducting layer 3 to terminal 2's one end this moment, and the terminal 2 tip that corresponds is its conducting terminal, and the other end of terminal 2 is stayed in the outside of base body 1 link, and the terminal 2 tip that corresponds is its link, for example uses the fixed glue to install terminal 2 in signal of telecommunication connecting hole.

The terminals 2 generally comprise inner ring terminals arranged at equal intervals around the circumference of the axis of the base 1 and outer ring terminals arranged at equal intervals around the axis of the base 1 and located outside the inner ring terminals, the number of the terminals 2 in the inner ring terminals is generally 1~3, and the number of the terminals 2 in the outer ring terminals is generally 8 to 16.

Because the coating thickness of conducting layer 3 is very thin, so in order to avoid terminal 2 to lead to the conducting layer 3 to appear the fault to lead to the fact to open circuit by the highly more electric capacity end that leads to of terminal protrusion base body 1, so accomplish terminal 2 and base body 1's the back of being connected, grind the flat processing to base body 1's electric capacity end, guarantee terminal 2's the terminal surface parallel and level of conducting end and base body 1 electric capacity end, thereby can effectively control terminal 2 and conducting layer 3 contact and avoid conducting layer 3 to have the disappearance when carrying out the current transfer, guarantee the stability that hemisphere resonance top base used.

The conducting layer 3 is a plating layer made of conducting materials, can be made of materials such as aluminum, gold, silver and the like, and is preferably made of aluminum for film plating to form an aluminum plating layer, so that the cost is reduced; at the same time toAvoid aluminized layer and air contact oxidation influence electric conductive property to reduce the stability of hemisphere resonance top base, preferably set up inoxidizing coating 4 in the conducting layer outside, the inoxidizing coating can be selected as SiO_xMaterials, e.g. SiO₂The material, because current base body is the glass material equally to conducting layer 3 covers in the outside of 1 electric capacity end of base body completely, can carry out batch processing simultaneously to a plurality of base bodies 1 when carrying out the coating film of inoxidizing coating 4 this moment, improves production efficiency.

Conducting layer 3 and inoxidizing coating 4 all can adopt the coating by vaporization mode to carry out the coating film and handle, because the combination effect between aluminized layer and the glass layer is superior to the combination between the current chromium-gold cladding material, can improve the structural strength and the life of hemisphere resonance top base, the electric capacity end of base body 1 can lead to electrically conductive effect to have the influence because of there being the glass inoxidizing coating when using, nevertheless thinner because of the thickness of glass inoxidizing coating, resistance is about 1 omega usually, so calculate the influence that the electric capacity changes and can eliminate the glass inoxidizing coating after setting up the influence factor according to the thickness of glass inoxidizing coating when using, guarantee hemisphere resonance top base's stability in use.

After the connection of the wiring terminal 2 of the base body 1, the evaporation of the conducting layer 3 and the evaporation of the protective layer 4 are finished, in the same way as the prior art, the electrode image is etched on the capacitor end of the base body 1 by utilizing the laser etching technology, and the electrode image and the metalized harmonic oscillator form a capacitor; when the electrode image is etched on the capacitance end of the base body 1, the protective layer 4 and the conductive layer 3 are etched at the same time to form a corresponding electrode image.

The above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the method of implementing the present invention. Other variations and modifications will be apparent to persons skilled in the art upon reading the foregoing description. This is not exhaustive of all embodiments.
