Background technology
Electrochemical sensor species is various, is that the world today uses a kind of most common sensor, is widely used in each
In industry, for detecting oxygen, hydrogen, toxic gas etc..Electrochemical sensor is mainly by electrode, electrolyte, permeable membrane etc.
Composition.Tested gas enters after electrochemical sensor, occurs irreversible chemical reaction in sensor internal, then by with electrode phase
Electric interfaces output current/voltage signal of connection.
In the prior art, electrochemical sensor electrodes are connected in a printed board being located on the outside of sensor, then are led to
The connectors such as contact pin, socket, the pad crossed in printed board and external equipment, which are realized, to be electrically connected.During using contact pin and socket, its
Defect is the increase in the height of sensor, in production application, it is necessary to increases the height of test chamber, can so increase the body of equipment
Product, while also increasing cost.During using pad, its notable defect is to need welding, in operation because of the temperature of flatiron
It is too high easily to damage sensor.
Another electric connecting mode of electrochemical sensor is that the gold being connected with sensor electrode is set in printed board
Belong to point, external equipment is realized with these metal dots by probe and is connected.But in installation, more emat sensor, it is extremely inconvenient：Must
These independent metal dots and probe alignment must be made, it must also be ensured that sensor does not rotate and moved after alignment.This is to sensing
Device, which is installed and changed, brings very big difficulty, so cannot widely use.
Utility model content

The electric connecting mode for learning sensor exists and installs and change constant, and it is fragile, the problem of cost is high.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of electrochemical sensor for having a ring interface, including electrochemical sensor, and located at electrochemical sensor end face
And the printed board with several annular metallic layers；The printed board includes two sides, and one facing to electrochemical sensor, another side
Outside, the printed board is provided with several pads or connector, electrochemical sensor towards the one side of electrochemical sensor
Electrode be connected by pad or connector with annular metallic layer.
Specifically, it is located in one side of the printed board outside covered with annular insulating barrier, several annular metallic layers
On the annular insulating barrier.Several described annular metallic layers are the circular ring metal layer of concentric, using printed board center as circle
The heart is outwards distributed in a determining deviation, and the center of circle of annular metallic layer is located on the axle center of electrochemical sensor.
In order to realize the connection of annular metallic layer and electrochemical sensor, each annular metallic layer is provided with least one
Via penetrates printed board and is connected with pad or connector.
For the position of fixed printed board, the printed board is embedded in the end face of electrochemical sensor.
In addition, the printed board is additionally provided with electronic system towards the one side of electrochemical sensor, the electronic system it is defeated
Enter end to connect by the electrode of pad or connector and electrochemical sensor, the output end of electronic system passes through pad or company
Fitting is connected with annular metallic layer.
Compared with prior art, the utility model has the advantages that：
(1) annular metallic layer of the present utility model as electrochemical sensor electrodes and electronic system interface, with outside
After the probe of equipment is contacted with these annular metallic layers, you can realize that electrochemical sensor is connected with external equipment.
(2) loop configuration of annular metallic layer can make electrochemical sensor with Arbitrary Rotation in the utility model,
And holding and the good contact of external equipment probe, reduce the difficulty that sensor is installed and changed.
(3) the utility model is provided with electronic system, again with numeral after can the output signal of sensor be handled
The modes such as signal, analog signal are exported.
(4) the utility model is simple to manufacture, and will not increase the cost of electrochemical sensor, not only possess novelty and creation
Property, and possess very high practicality, it is its large-scale popularization and application, has established solid foundation.
