Abstract
The utility model discloses a kind of electrode of piezoelectric actuator, it is related to piezoelectric actuator Element Technology field, primary structure includes the extreme, groove and pole item being wholely set, pass through the setting of pole item, the overall structural strength of electrode is enhanced, the yield rate of electrode is substantially increased, reduces the manufacturing cost of electrode, the using effect for improving electrode extends the service life of electrode.
Description
Technical field
The utility model relates to piezoelectric actuator Element Technology fields, more particularly to a kind of electrode of piezoelectric actuator.
Background technique
The electrode of piezoelectric actuator is as a kind of common piezoelectric actuator element, but electrode is in the fabrication process, finished product
Rate is lower, and electrode is easily damaged in use process, and the service life of electrode is low.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of electrode of piezoelectric actuator, which has higher
Structural strength, longer service life.
To achieve the above object, the utility model provides following scheme:
The utility model provides a kind of electrode of piezoelectric actuator, including one extreme, and it is recessed that described extreme one end is connected with one
Slot, the top of the groove and the groove are hatch frame far from the extreme side.
Optionally, the groove has the side wall of an arc close to the extreme side.
It optionally, further include pole item, the pole item is set to the extreme two sides and the groove close to the pole
Hold the two sides at the top of side.
Optionally, the pole item is set to the two sides of the groove top.
Optionally, the pole item is cuboid-type structure.
Optionally, the top of the pole item and the extreme top flush.
Optionally, the inside flush on the inside of the pole item with the recess sidewall.
Optionally, the width of the pole item is greater than the thickness of the recess sidewall.
The utility model achieves following technical effect compared with the existing technology:
The electrode primary structure of piezoelectric actuator in the utility model includes the extreme, groove and pole item being wholely set,
By the setting of pole item, the overall structural strength of electrode is enhanced, substantially increases the yield rate of electrode, reduces the system of electrode
This is caused, the using effect of electrode is improved, extends the service life of electrode.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without any creative labor, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the electrode of the utility model piezoelectric actuator；
Fig. 2 is second of structural schematic diagram of the electrode of the utility model piezoelectric actuator.
Description of symbols: 1, extreme；2, pole item；3, groove.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one:
As shown in Figure 1, the present embodiment provides a kind of electrode of piezoelectric actuator, including one extreme 1, described extreme 1 one end
It is connected with a groove 3, the top of the groove 3 and the groove 3 are hatch frame far from extreme 1 side.
In this specific embodiment, the groove 3 has the side wall of an arc close to extreme 1 side.Further include
Pole item 2, the pole item 2 be set to extreme 1 two sides and the groove 3 close to extreme 1 side top two
Side.The pole item 2 is cuboid-type structure.The top of the pole item 2 with described extreme 1 top flush.In the pole item 2
The inside flush of side and 3 side wall of groove.The width of the pole item 2 is greater than the thickness of 3 side wall of groove.
Embodiment two:
The present embodiment is improved embodiment on the basis of example 1.As shown in Fig. 2, the pole item 2 is set to institute
State the two sides at 3 top of groove.The increase of 2 length of pole item, keeps the integral strength of electrode higher, electrode yield rate in the fabrication process
Higher, service life is also longer.
It applies specific case in this specification to be expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
