Further, described open slot extends to the support ring middle part vertically from the support ring lower end.
Further, described open slot extends to the support ring upper end vertically from the support ring lower end.
Further, described support ring passes through in the enclosure section of circlip axial location.
Further, the lower surface of described support ring is pressed on the upper surface of core component, and the madial wall of described shell is provided with the locating slot of location circlip.
Further, be provided with the dead ring that the insulation of stitch and support ring is separated in the described support ring, the lower surface of described dead ring is pressed on the upper surface of core component.
Further, described support ring is provided with the pillar to downward-extension, and the outer ring surface of described ceramic core body component is provided with the groove with stanchions, and described pillar is inlaid in and makes open slot corresponding with stitch good in the groove.
Further, described support ring is metal ring.
Further, described support ring is nonmetallic circular ring, and the upper end of described nonmetallic circular ring is provided with sealing, and described stitch passes sealing and is electrically connected with circuit board.
After adopting technique scheme, the present invention has following advantage: be provided with after the open slot, climbing arc distance increases greatly, has improved to a great extent the insulativity of pressure transducer; And on this basis, safety groove can also be set, further increase climbing arc distance, improve the insulativity of pressure transducer.
