Abstract
The invention discloses a pressure sensor mounting structure. The pressure sensor mounting structure comprises a base internally provided with a hollow cavity, a pressure sensor is mounted in the hollow cavity, a sunk cavity is arranged on the inner side of the hollow cavity, an O-ring is arranged in the sunk cavity and enables the pressure sensor to be isolated from the base, a locking ring for pressing the pressure sensor is connected onto the base, and the pressure sensor is electrically connected with a circuit board. The pressure sensor mounting structure has the advantages that the pressure sensor is isolated from the base through the O-ring and does not directly contact with the inner wall of the base, and accordingly the influences of the base on the pressure sensor are avoided, working stability of the pressure sensor is guaranteed, and the pressure sensor has good measurement precision.
Description
Technical field
The present invention relates to a kind of mounting structure of sensor.
Background technology
Traditional pressure transducer mounting structure comprises pedestal, has cavity in the pedestal, and pressure transducer is installed in the cavity, and an end of pressure transducer contacts with base internal wall, and the other end compresses by retaining ring.Yet in this pressure transducer mounting structure, pressure transducer directly contacts with base internal wall, makes pressure transducer be subject to easily the impact of pedestal, reduces its job stability, affects measuring accuracy.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of pressure transducer mounting structure, and pressure transducer is not directly contacted with base internal wall, ensures the stability of its work, has good measuring accuracy.
In order to solve the problems of the technologies described above, a kind of pressure transducer mounting structure of the present invention, comprise pedestal, have cavity in the pedestal, pressure transducer is installed in the cavity, described cavity inboard is provided with heavy chamber, should be provided with O type circle in the heavy chamber, this O type circle makes pressure transducer and pedestal isolation, is connected with the retaining ring that pressure transducer is compressed on the pedestal, and described pressure transducer is electrically connected with circuit board.
As improvement of the technical scheme, be provided with copper ring between described pressure transducer and the retaining ring.
As improvement of the technical scheme, described retaining ring is equipped with outer cover outward, and it is inner that described circuit board is arranged on this outer cover.
As improvement of the technical scheme, described outer cover end is equipped with cable rope head, has the high-temperature electric cable that is connected with circuit board in this cable rope head.
As improvement of the technical scheme, described retaining ring arranged outside has circular protrusion, and this circular protrusion has breach, and described breach is divided into first, second tie point with circular protrusion, described the first tie point and retaining ring welding, the second tie point and outer cover welding.Described retaining ring is connected with base thread.
The invention has the beneficial effects as follows: this pressure transducer mounting structure makes pressure transducer and pedestal isolation by O type circle, pressure transducer does not directly contact with base internal wall, avoid being subject to the impact of pedestal, ensure the stability of its work, have good measuring accuracy.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of pressure transducer mounting structure of the present invention, comprise pedestal 1, have cavity 2 in the pedestal 1, pressure transducer 3 is installed in the cavity 2, described cavity 2 inboards are provided with heavy chamber 4, should be provided with O type circle 5 in the heavy chamber 4, this O type circle 5 makes pressure transducer 3 and pedestal 1 isolation, is connected with the retaining ring 6 that pressure transducer 3 is compressed on the pedestal 1, and described pressure transducer 3 is electrically connected with circuit board 7.Described retaining ring 6 is threaded with pedestal 1.When installing, first the benchmark copper sheet is put into pedestal, then just put into respectively pressure transducer, copper ring, just with retaining ring pressure transducer is locked, just adopt method of scoring to make a mark after the locking; Then, unclamp retaining ring and take out successively copper ring, pressure transducer, copper sheet, then just put into O type circle, pressure transducer, copper ring again, just lock with retaining ring at last.This all just can be fine the decrement of control O type circle, do not leak when guaranteeing wide range work.This pressure transducer mounting structure makes pressure transducer and pedestal isolation by O type circle, and pressure transducer does not directly contact with base internal wall, avoids being subject to the impact of pedestal, ensures the stability of its work, has good measuring accuracy.
In the present embodiment, be provided with copper ring 8 between described pressure transducer 3 and the retaining ring 6.Can make pressure transducer 3 suffered pressure pass to retaining ring 6 and pedestal 1 by copper ring 8, such structure also avoid simultaneously the surface circuit pressurized and making of pressure transducer 3 output is exerted an influence.
Outside the described retaining ring 6 outer cover 9 is housed, described circuit board 7 is arranged on this outer cover 9 inside, makes circuit board obtain good protection.Described outer cover 9 ends are equipped with cable rope head 10, have the high-temperature electric cable 11 that is connected with circuit board 7 in this cable rope head 10, so that the mounting structure of cable is more firm.
Described retaining ring 6 arranged outside have circular protrusion 12, this circular protrusion 12 has breach 13, described breach 13 is divided into first, second tie point 14,15 with circular protrusion 12, described the first tie point 14 and retaining ring 6 welding, the second tie point 15 and outer cover 9 welding, be convenient to welding operation, and make product structure more firm, just more stable during pressure transducer work.
The above only is preferential embodiment of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
