Abstract
The utility model discloses a pressure sensor mounting structure, comprising a base. The base internally comprises a cavity. A pressure sensor is installed in the cavity. An inner side of the cavity is provided with a sink cavity. The sink cavity is internally provided with an O-shaped ring. The O-shaped ring separates the pressure sensor from the base. A locking ring for compressing the pressure sensor is connected onto the base. The pressure sensor is electrically connected with a circuit board. The pressure sensor mounting structure makes the pressure sensor be separated from the base through the O-shaped ring, the pressure sensor does not directly contact an inner wall of the base to avoid the influence of the base, the work stability of the pressure sensor is guaranteed, and the pressure sensor can have good measuring precision.
Description
Technical field
The utility model relates to a kind of mounting structure of sensor.
Background technology
Traditional pressure transducer mounting structure comprises pedestal, has cavity in pedestal, and pressure transducer is installed in 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 easily be subject to the impact of pedestal, reduces its job stability, affects measuring accuracy.
The utility model content
The technical problems to be solved in the utility model is to provide 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 utility model, comprise pedestal, have cavity in pedestal, pressure transducer is installed in cavity, described cavity inboard is provided with heavy chamber, should be provided with O type circle in heavy chamber, this O type circle makes pressure transducer and pedestal isolation, is connected with the retaining ring that pressure transducer is compressed on pedestal, and described pressure transducer is electrically connected to circuit board.
As improvement of the technical scheme, be provided with copper ring between described pressure transducer and 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 beneficial effects of the utility model are: 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
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of pressure transducer mounting structure of the present utility model, comprise pedestal 1, have cavity 2 in pedestal 1, pressure transducer 3 is installed in cavity 2, described cavity 2 inboards are provided with heavy chamber 4, should be provided with O type circle 5 in 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 pedestal 1, and described pressure transducer 3 is electrically connected to 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 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 retaining ring 6.Can make the suffered pressure of pressure transducer 3 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.
The outer outer cover 9 that is equipped with of described retaining ring 6, described circuit board 7 are arranged on this outer cover 9 inside, make 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, make the mounting structure of cable 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 is only preferential embodiment of the present utility model, as long as within realizing that with basic identical means the technical scheme of the utility model purpose all belongs to protection domain of the present utility model.
