Side seal mode, and using the sealing of double O-rings, can make the aging deformation of O-ring is improved, when long-time service, are O-shaped
Circle will not leak, and sealing and anti-leakage performance is more preferably more preferable with effect；At the same time using the Seal Design side of hard pcb board and clamp spring
Formula, hard pcb board can ensure that circuit part is not easily susceptible to damage and improves the reliability of circuit part, and clamp spring is clamped in pedestal
Stronger leakproofness can be played；Patch cord uses the outlet method of direct cable line, more convenient and simple in production and installation
It is single, it is also very firm.
Technical solution is used by the utility model solves its technical problem：A kind of pressure sensor of side seal, bag
The pedestal with inner cavity and the sensor installed arranged on pedestal inner cavity and with its fitted seal are included, the interior bottom of pedestal inner cavity is equipped with
The boss of protrusion, sensor are equipped with the pressure sensitive endoporus with the installation of boss fitting, pass through between pressure sensitive endoporus and boss
Double O-rings realize side seal, and the outer wall of sensor is mutually compressed with the inner wall of pedestal inner cavity；Further include in the pedestal intracavitary and
The hard pcb board of jam sensor, it is connected above sensor and with hard pcb board and is directly led out with direct outlet method from pedestal
Cable.The pressure sensitive endoporus of sensor and the boss of pedestal are installed, by the inner side of double O-rings and gauge hole into
Row side seal is protected, and forms good sealing effect.Simultaneously directly outlet is attached welding cable line on hard PCB, makes two section sides
Formula is more simple and convenient, and uniformity is stronger.
Further, jam sensor is equipped between the hard pcb board and sensor and realizes the clamp spring of sealing effect,
Clamp spring, which shrinks to insert, to be recovered to original state behind pedestal inner cavity and is caught in the groove of pedestal inner cavity, be equipped between clamp spring and sensor every
Clamp spring is opened to contact with the surface circuit of sensor and cause to export undesirable copper packing.Copper packing and clamp spring, copper packing are placed on sensor
Ensure clamp spring contact with sensor surface circuit and cause to export it is bad, clamp spring contraction be put into behind pedestal inner cavity recover to
Original state is simultaneously caught in the groove of pedestal, realizes good sealing effect.
Further, intracavitary is additionally provided with the shield line seat compressed at the top of hard pcb board, shield line seat and hard PCB in the pedestal
The waveform bullet that being additionally provided between plate prevents shield line seat from damaging hard pcb board is situated between.Waveform bullet is placed on hard PCB to be situated between, prevent hard PCB with
Shield line seat damages hard PCB after compressing.
Further, the hard pcb board is connected with cable using welding manner, and cable passes through shield line seat, pedestal
Top packs tightly shield line seat equipped with bound edge.Shield line seat forms bound edge processing after being installed on pedestal inner cavity, keeps the sealing effect after compressing
Fruit.
Further, the hard pcb board is also connected by Sensor output with sensor.
In conclusion the pressure sensor of the side seal of the utility model uses the side for carrying out side seal to sensor close
Envelope mode, and using the sealing of double O-rings, can make the aging deformation of O-ring is improved, O-ring during long-time service
Be not in leakage, sealing and anti-leakage performance is more preferably more preferable with effect；The Seal Design mode of hard pcb board and clamp spring is used at the same time,
