Abstract
The invention discloses a pressure sensor shell structure comprising a cylinder-shaped pedestal and a connecting plug. One end of the connecting plug is arranged in a cavity of the pedestal. The matching end part of the pedestal and the connecting plug is provided with an "O "-shaped ring. The matching side part of the pedestal and the connecting plug is provided with a groove and the "O "-shaped ring which is matched with the groove so that sealing performance of matching between the pedestal and the connecting plug is enhanced, and position of the connecting plug in the pedestal before rolling depression can be ensured and quality of the rolling depression pedestal side part is enhanced.
Description
Technical field
The present invention relates to sensor technical field, especially relate to a kind of pressure transducer shell structure.
Background technology
Current pressure transducer shell structure mainly comprises the pedestal of metal and the plug head of plastics, and columniform connection-peg is arranged in base cavity, and susceptor edge portion is fixed on connection-peg in pedestal by roll extrusion.
Existing this shell structure has the following disadvantages: what between connection-peg and pedestal, coordinate is not tight, is prone to gas leak phenomenon; Before the roll extrusion of susceptor edge portion, connection-peg is arranged in pedestal, gapped between connection-peg and pedestal, and malposition affects roll extrusion quality.
Summary of the invention
Not enough for prior art, technical matters to be solved by this invention is to provide a kind of pressure transducer shell structure, and it improves the assembly quality between pedestal and connection-peg.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of pressure transducer shell structure, comprise columniform pedestal and connection-peg, described connection-peg one end is located in the cavity of pedestal, at described pedestal and the connection-peg end position place that matches, is provided with "O"-ring.
Further, described connection-peg is provided with the groove matching with "O"-ring.
Between the limit portion of described pedestal and connection-peg, be provided with fluid sealant.
The cross section of described groove is semicircle.
The present invention compared with prior art, have the following advantages: by the "O"-ring that groove is set and matches with groove in pedestal and connection-peg mating edge portion, improve the sealing coordinating between pedestal and connection-peg, and can guarantee roll extrusion anterior plug-in head position in pedestal, improve roll extrusion pedestal quality of edges.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this instructions and the mark in figure are briefly described:
Fig. 1 is pressure transducer shell structure cut-open view of the present invention.
In figure: 1. plug head, 2. pedestal, 21. connectors, 22. limit portions, 3. ceramic diaphragm, 4. rubber ring, 5. "O"-ring.
Embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention.
As shown in Figure 1, this pressure transducer shell structure, comprises columniform pedestal 2 and connection-peg 1, connection-peg is provided with contact pin in 1 one end, and connection-peg 1 other end is located in pedestal 2 one end cavitys, and pedestal 2 other ends are connector 21, connector 21 outsides are provided with screw thread, are convenient to fixed installation.
At pedestal 2 and the connection-peg 1 end position place that matches, be provided with "O"-ring 5, and be provided with the groove matching with "O"-ring 5 on connection-peg 1, preferred, the cross section of groove be semicircle, raising "O"-ring fixed mass.
When assembling, first "O"-ring 5 is set in the groove of connection-peg 1, again connection-peg is injected in pedestal, "O"-ring crimp is fixed in pedestal by connection-peg reliably, connection-peg is fixed in the position of pedestal, then the limit portion of pedestal is carried out to roll extrusion operation, when roll extrusion operates, "O"-ring has certain elasticity, can improve roll forming quality.
Between the limit portion 22 of pedestal 2 and connection-peg 1, be provided with fluid sealant, by fluid sealant, further improve the reliability of fixing seal.
Between connection-peg 1 inner end and pedestal 2 cavity bottoms, be provided with ceramic diaphragm 3, ceramic diaphragm 3 is to be fixed in pedestal by rubber ring 4 sealings.Sensor in use, if rubber ring is aging or the existence damage that is corroded causes sealing effectiveness variation, as two sealing defence lines, road, guarantees sealing property by the "O"-ring 5 between plug head 1 and pedestal 2, improves the serviceable life of pressure transducer.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
