Abstract
The invention discloses a hydraulic sensor, comprising a base, an O-shaped ring, a stopping ring, a ceramic base, a copper ring, a flexible circuit board, and a plastic plug piece; the stopping ring and the ceramic base are arranged in the base, a spring is arranged between the ceramic base and the copper ring; one end of the spring is connected with the ceramic base, and the other end is connected with the copper ring. By adopting the structure, the invention has the following advantages: 1, by adopting the technical solution, the product can be sealed; besides, when the measured medium is changed from liquid to solid, the pressure on the product can be increased instantaneously by 10-30 times, thus the spring can generate the compression and deformation, volume is increased and pressure intensity of the inner part is reduced, thereby playing a role of protection; and 2, when the measured medium is changed from solid to liquid, the spring can restore an original edge-coating state, thereby tightness of a product cannot be affected.
Description
Technical field
The present invention relates to a kind of hydraulic pressure transducer.
Background technology
At present, traditional hydraulic pressure transducer in use, fluid pressure in measuring sealed environment, particularly this liquid is in the situation of freezing easily under certain environment or expanding, the pressure of measuring is had to go to the toilet in blink and is increased severely greatly, surpasses the maximum bearing capacity of sensor and causes sensor to damage.
Summary of the invention
Technical matters to be solved by this invention is for the deficiencies in the prior art, to provide a kind of bearing capacity strong hydraulic pressure transducer.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of hydraulic pressure transducer, comprise pedestal, O type circle, back-up ring, ceramics seat, copper ring, flexible PCB, plastics connector, described back-up ring and ceramics seat all are arranged in the pedestal, be provided with spring between described ceramics seat and the copper ring, described spring one end is connected with ceramics seat, and the other end is connected with copper ring.
Be welded with chip, electric capacity and resistance on the described flexible PCB.
Described chip model is MP0529.
Described flexible PCB and plastics connector welding.
A kind of manufacture method of hydraulic pressure transducer, described method may further comprise the steps:
A) be assembled to successively back-up ring, O type circle, ceramics seat in the pedestal;
B) then the complete plastics connector of spring, copper ring and electrical connection of packing into carries out bound edge, plays sealing effectiveness by the compression deformation of O type circle.
The present invention adopts said structure, have the following advantages: 1, adopt technique scheme, can realize the sealing of product, in addition when the medium of measuring is varied to solid by liquid, the pressure that product is experienced is instantaneous can to increase 10～30 times, and at this moment spring can produce compression deformation, increases volume, reduce inner pressure, thereby play a protective role; 2, when measuring media is varied to liquid by solid, spring can recover again the form of original bound edge, thereby can not affect the sealing of product.
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;
In Fig. 1,1, pedestal; 2, O type circle; 3, back-up ring; 4, pottery; 5, spring; 6, copper ring; 7, flexible PCB; 8, plastics connector.
Embodiment
A kind of hydraulic pressure transducer as shown in Figure 1, comprise pedestal 1, O type circle 2, back-up ring 3, ceramics seat 4, copper ring 6, flexible PCB 7, plastics connector 8, back-up ring 3 and ceramics seat 4 all are arranged in the pedestal 1, be provided with spring 5 between ceramics seat 4 and the copper ring 6, spring 5 one ends are connected with ceramics seat 4, and the other end is connected with copper ring 6.
Be welded with chip, electric capacity and resistance on the flexible PCB 7.
The chip model is MP0529.
A kind of manufacture method of hydraulic pressure transducer, method may further comprise the steps:
A) be assembled to successively back-up ring, O type circle, ceramics seat in the pedestal;
B) then the complete plastics connector of spring, copper ring and electrical connection of packing into carries out bound edge, plays sealing effectiveness by the compression deformation of O type circle.
Mounting spring 5 between ceramics seat 4 and the copper ring 6, after the follow-up operation (bound edge) of process, spring should be not exclusively compressed, also has certain compression surplus, when the medium of measuring during because of the change (becoming solid by liquid) of environment, along with the increase of pressure, spring can be continued compression, the pressure of the inside that reduces is in order to avoid pottery is breakdown.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
