The sealing structure of the sensor and the pressure sensor are simple in structure and are convenient to manufacture; the contact area between the inner wall of the shell and the gel can be increased through the resistance increasing structure, the stressed area of the gel is increased, and the compression strength of the gel is strengthened.
Description
Technical field
The utility model relates to sensor, particularly the pressure transducer of a kind of hermetically-sealed construction of sensor and employing sealing structure.
Background technology
Sensor element in the pressure transducer is to seal through gelinite a bit, prevents the tested media leakage, guarantees the induction precision of sensor element.Because sensor element passes gelinite and gives Connection Element with the pressure signal transmission that receives; It is signal processing circuit board; Thereby convert pressure signal to electric signal output, thus gelinite is wanted and housing between guarantee that not having relatively moves and just can make that sensor element accurately responds to and transmit pressure signal.
The utility model content
The utility model problem to be solved just provides a kind of hermetically-sealed construction of sensor, and is simple in structure, easy to make, strengthens the compressive resistance of gelinite.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of hermetically-sealed construction of sensor; Comprise the gelinite that is located in the housing, it is characterized in that: also comprise be located on the inner walls increase contact area between gelinite and the housing increase the resistance structure.
Further, the said resistance structure that increases comprises and establishes at least one annular protrusion, and annular protrusion is located on the inner walls and the gelinite corresponding position, and gelinite solidifies the back annular protrusion and is stuck in the gelinite.
Further, the said resistance structure that increases comprises and establishes at least one annular groove, and annular groove is located on the inner walls and the gelinite corresponding position, and gelinite is stuck in the annular groove after solidifying.
Further, the said resistance structure that increases comprises at least one annular protrusion and at least one annular groove.
The utility model also provides a kind of pressure transducer in addition; It is characterized in that: comprise housing and be located at and adopt above-mentioned hermetically-sealed construction to realize the sensor element of sealing in the housing; Above gelinite, be provided with the signal processing circuit board that pressure signal is converted to electric signal; The output line of sensor element passes gelinite and is connected with signal processing circuit board, and the housing upper end is connected with electrical outlets.
Further, the bottom of said electrical outlets is provided with the four-core contact pin interface, is respectively power interface, ground connection interface, signal output interface and debugging interface, and the four-core contact pin interface is connected with signal processing circuit board through connecting line.Can after encapsulation, debug through debugging interface, be convenient to eliminate the influence of encapsulation process, guarantee the induction precision of sensor element sensor element.
Further, being provided with the riveted joint sheet on the said housing also rivets through riveted joint sheet and electrical outlets.Install easy to connect quick.
Further, riveted joint place of said riveted joint sheet and electrical outlets scribbles marine glue.Prevent that the external water impervious from getting in the housing.
After adopting technique scheme, the utlity model has following advantage: get up to increase the contact area between inner walls and the gelinite through annular groove or convex annular, increase the lifting surface area of gelinite, strengthen the compressive resistance of gelinite.
