Description
Technical field
The utility model relates to a kind of infrared sensor, specifically, relates to a kind of novel binary channels pyroelectric infrared sensor.
Background technology
Existing binary channels pyroelectric infrared sensor adopts the field effect transistor wafer directly to bind technology mostly and makes, and owing to very high to production technology and production environment requirement, causes the production cost height of binary channels pyroelectric infrared sensor; Existing binary channels pyroelectric infrared sensor adopts packaged field-effect tube to make in addition, though this mode cost is lower, but because the field effect transistor volume that encapsulated is big, the binary channels pyroelectric infrared sensor volume that causes making increases, and has limited the usable range of sensor itself.
For this reason, people are seeking a kind of desirable technical solution always.
Summary of the invention
The utility model provides the novel binary channels pyroelectric infrared sensor that a kind of volume is small and exquisite, making is simple, production cost is low, production efficiency is high, usable range is wide at the deficiencies in the prior art.
The technical scheme that the utility model adopted is as follows: a kind of novel binary channels pyroelectric infrared sensor, it includes pipe cap, be arranged on the window of pipe cap head end, be arranged on the infrared fileter of pipe cap inboard, be installed in the base of pipe cap end, pass pin and the sensor circuit that is connected pin that base is provided with, described sensor circuit includes two groups of infrared-sensitive units and two field effect transistor, in described pipe cap, be provided with a circuit board, described circuit board is arranged on the described pin, described sensor circuit is arranged on the described circuit board, wherein, two groups of infrared-sensitive units are arranged on described circuit board upside, two field effect transistor are arranged on described circuit board downside, and two field effect transistor are supported between described circuit board and the described base.
Based on above-mentioned, two groups of infrared-sensitive units and two field effect transistor adopt SMT automatic chip mounting technology to be attached to described circuit board upside and downside respectively.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, this sensor is by the single layer board structure, make full use of narrow space, do not increased sensor bulk and reducing under the prerequisite of field effect transistor volume, realized the binary channels pyroelectric sensor preparation of smaller size smaller, simultaneously, the single layer board structure of this sensor can also realize SMT automatic chip mounting technology, has significantly improved the make efficiency of sensor, has reduced production cost;
The two point supporting role of two field effect transistor, guaranteed the level of circuit board, and then guaranteed the visual angle consistance of two groups of infrared-sensitive units, simultaneously, the distance of infrared-sensitive unit with window furthered, promptly raise the position of infrared-sensitive unit, enlarged the visual angle of sensor, can improve the detection performance of sensor greatly;
This novel binary channels pyroelectric infrared sensor has the advantage that volume is small and exquisite, making is simple, production cost is low, production efficiency is high, usable range is wide.
