Abstract
The utility model 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 connector, wherein 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 of the spring is connected with the copper ring. By adopting the structure, the utility model has the following advantages: 1) by adopting the technical scheme, a product can be sealed, and when a measured medium is changed from liquid to solid, the pressure on the product can be increased instantaneously by 10-30 times, and the spring is compressed and deformed to increase the volume and reduce the pressure intensity inside to achieve a role of protection; and 2) when the measured medium is changed from solid to liquid, the spring can restore to an original edge-coating state so that the tightness of the product cannot be affected.
Description
Technical field
The utility model 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 under 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.
The utility model content
Technical problem to be solved in the utility model is at 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, the technical solution of the utility model 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 the welding of plastics connector.
A kind of manufacture method of hydraulic pressure transducer, described method may further comprise the steps:
A) be assembled to back-up ring, O type circle, ceramics seat in the pedestal successively;
B) pack into spring, copper ring and be electrically connected the plastics connector that finishes carry out bound edge then, play sealing effectiveness by the compression deformation of O type circle.
The utility model 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 the form of original bound edge again, thereby can not influence the sealing of product.
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;
In Fig. 1,1, pedestal; 2, O type circle; 3, back-up ring; 4, ceramics seat; 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.
Flexible PCB 7 and 8 welding of plastics connector.Flexible PCB 7 all is to couple together with the pattern of welding with ceramics seat 4 and plastics connector 8.
A kind of manufacture method of hydraulic pressure transducer, method may further comprise the steps:
A) be assembled to back-up ring, O type circle, ceramics seat in the pedestal successively;
B) pack into spring, copper ring and be electrically connected the plastics connector that finishes carry out bound edge then, play 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.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
