Description
Technical field
The utility model relates to a kind of small-sized sealing high-voltage electric connector based on ceramic sealed knot, belongs to technical field of electric connectors.
Background technology
Existing minitype high voltage electric connector insulator material generally is polytetrafluoroethylene, PPS, the plastics such as PEEK, its resistance to elevated temperatures, abrasion resistance properties, corrosion resistance, insulation property all do not have the ceramic material that adopts in the utility model good, pottery also has plasticity poor simultaneously, the problem that fragility is high, cause the ability of resisting thermal stress and shock loading, the utility model selects effective method of attachment according to requirements, Ceramic and metal joining is got up to obtain ceramet composite component, the advantages of the two can be got up, give full play to the excellent properties of ceramic material and broaden application scope.
Existing sealed electrical connector encapsulating method is generally sealant pouring and sealing and glass frit seal, and it is not high that sealant pouring and sealing generally seals index, and adopt the electric connector of glass frit seal otherwise compressive property poor, or sintering glass quality be difficult to ensure.The utility model adopts this new technology of ceramic sealed knot to ensure the air-tightness of junction, obtains good effect.
Ceramic material has excellent high temperature resistant, wear-resistant, corrosion resistance and density is low, the feature of good insulating, has broad application prospects at automobile, military project, electronic flight space industry.Pottery also has plasticity poor simultaneously, the problem that fragility is high, cause the ability of resisting thermal stress and shock loading, according to requirements select effective method of attachment, Ceramic and metal joining is got up to obtain ceramet composite component, the advantages of the two can be got up, give full play to the excellent properties of ceramic material and broaden application scope.
The method of attachment of pottery and metal is mainly divided into mechanical connection, bonding and welding.Mechanical joining methods at present for connecting pottery and metal mainly contains bolt and hot jacket, and the difficulty of bolt processing is large, and joint lacks air-tightness; Hot jacket can produce very large residual stress, for ensureing that air-tightness causes working temperature also can not be very high.Bonding simple to operate, joint air-tightness is good, but intensity is low, and Long-Time Service can make all have hydraulic performance decline.Strength of welded joint is high, high temperature resistant, can ensure certain air-tightness, and to connector geometry and dimensional requirement not high.
People expect the electric connector obtaining a kind of small-sized sealing high pressure, and the application of ceramic sealed knot makes electric connector in the better effects if of miniaturized sealed high pressure electric connector.
