Abstract
The utility model discloses a threaded core body which comprises a pressure ring, a pressure-sensitive chip, a membrane, a base and a plurality of pins, wherein the pressure ring is provided with a locking hole, the pressure-sensitive chip is isolated from the base by a ceramic gasket, the exterior of the base is provided with external threads, and the threaded core body is connected with internal threads inside a pressure inlet head through the external threads and is locked through the locking hole. Compared with a PC30 threaded core body in the prior technical scheme, the threaded core body is locked through the locking hole, the threads of the core body are tightly buckled with threads of a pressure inlet head of a customer, the bearing pressure of the core body is increased, and the occupied space is reduced through a rear-end welding surface.
Description
Technical field
The utility model relates to a kind of screw thread core body.
Background technology
PC30 screw thread core body is a core component of making pressure transducer and pressure unit, as a kind of high performance pressure-sensitive component, it adopts integrated threaded structure, has the characteristic of stable, reliable and can be anti-very high static pressure, is specially adapted to the bigger occasion of pressure.
But existing P C30 type screw thread core body, length is longer, and when being encapsulated in the transmitter housing, it is big to take up room, and can't do the small size transmitter.In order to address this problem, I take charge of and have designed M16B screw thread core body.
The utility model content
The utility model purpose is to provide a kind of screw thread core body at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
A kind of screw thread core body of the utility model, comprise pressure ring, presser sensor chip, diaphragm, base and a plurality of pin, on the described pressure ring locking hole is set, presser sensor chip is isolated by ceramic gasket and base, the outer setting external thread of base, the described screw thread core body internal thread by external thread and entrance pressure head inside joins and by described locking hole locking.
Described diaphragm is sealed in silicone oil in the base, and base bottom oil-out seals by steel ball.
Described base bottom is provided with face of weld.
The utility model is compared with prior art scheme PC30 screw thread core body, the major advantage of the technical program is to tighten by locking hole, core body screw thread and client's entrance pressure head thread staples together, and has increased the bearing pressure of core body, has reduced occupation space by the rear end face of weld.
Description of drawings
Fig. 1: the utility model schematic appearance;
The sectional view of Fig. 2: Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of screw thread core body of the utility model comprises pressure ring 1, presser sensor chip 4, diaphragm 5, base 6 and a plurality of pin 7, on the described pressure ring 1 locking hole is set, and presser sensor chip 4 is isolated by ceramic gasket 2 and base 6.The outer setting external thread C of base 6, the described screw thread core body internal thread by external thread C and entrance pressure head inside joins and by described locking hole locking.Presser sensor chip is connected with pin 7 by spun gold 3.
Described diaphragm 5 is sealed in silicone oil 8 in the base 6, and base 6 bottom oil-outs are by steel ball 9 sealings.
Described base 6 bottoms are provided with face of weld B.
Principle of work of the present utility model is: pressure ring 1 welds together by welding A face with base 6, Silicon pressure sensitive chip (element 4 among the figure) is encapsulated in the special base (element 6 among the figure), impressed pressure is delivered to the silicone oil (element 8 among the figure) that is sealed in the base by diaphragm (element 5 among the figure), be delivered on the presser sensor chip by silicone oil again, presser sensor chip does not directly contact measured medium, forms tonometric structure of whole solid state.
The utility model:
⑴ designed locking hole ( element 10,11 among the figure).
⑵ designed rear end face of weld: B;
The internal thread of the external thread C of the utility model core body and the entrance pressure head inside that the client provides joins, and after firmly tightening by locking hole ( element 10,11 among the figure), the face of weld by face of weld 1 and client welds together again.
Advantage after the optimization is: 1. can anti-very big pressure; 2. reduced occupation space.
The above only is a preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
