Description
Technical field
The present invention relates to a kind of closed type high voltage direct current relays.
Background technology
High voltage direct current relay includes insulating boot and yoke, and insulating boot and yoke are formed with to accommodate stationary contact component and move and touch
The chamber of point component, stationary contact component include exit and stationary contact, and exit is mutually fixed with insulating boot and extends to insulating boot
Outside, wherein, chamber domestic demand vacuumizes and is filled with inert gas.At present in technology, insulating boot is mostly plastic material or ceramic material
Matter uses the insulating boot fluid sealant that can arrange in pairs or groups of plastic material to be sealed processing to chamber to ensure the leakproofness of chamber, to modeling
The contact position of material insulating boot and yoke is sealed glue sealing, and is sealed glue to the contact position on the outside of exit and insulating boot
Sealing；Using the rigidity of the insulating boot of ceramic material, then the rigidity guarantee product structure by ceramic material in itself, so as to ensure
The leakproofness of chamber.
Plastic insulation cover collocation sealant pouring and sealing mode have the production cycle is shorter, technological requirement is relatively low, production cost compared with
The advantages of low, but plastic insulation covers on that softening can be affected by temperature in long use, and fluid sealant, which can be also affected by temperature, is burnt hair
Huang, the inert gas of chamber have disclosure risk；And fluid sealant is affected by temperature and can expand with heat and contract with cold, meeting between fluid sealant and exit
It has the gap, the generation of explosion accident can be caused.
Using the relay of ceramic material insulating boot, due to the rigidity of ceramic insulation cover in itself, use also only can for a long time
Ceramic insulation cover crack is caused, the danger without Fire explosion occurs, but need to carry out using the relay of ceramic insulation cover
The soldering of the soldering of ceramic insulation cover and yoke, exit and ceramic insulation cover, the production cycle is longer, want production cost compared with
It is high.
The content of the invention
The object of the present invention is to provide a kind of leakproofness height, the height that can guarantee relay performance, reduce production cost
Straightening current relay.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of closed type high voltage direct current relay, including exhausted
Edge cover and yoke, the yoke, which upwardly extends, is formed with yoke fixed part cylindrical in shape, the insulating boot include top, top to
Under be extended with insulating boot fixed part cylindrical in shape, the top coordinates the cup-like structure for forming back-off with insulating boot fixed part,
The yoke coordinates the chamber for being formed with to accommodate movable contact and stationary contact, the insulating boot fixed part lower end with insulating boot
With the mutual thread fitting of yoke fixed part, set on the downside of the insulating boot fixed part lower end outside or insulating boot fixed part lower end
It is equipped with the first sealing ring, the thread fitting position of the insulating boot fixed part lower end and yoke fixed part is filled with sealing glue.
Wherein, insulating boot is made of the isolation material of non-plastic, such as ceramics, makes the relay of the present invention will not be by temperature
Degree influences to soften there is a situation where insulating boot, can avoid the risk that inert gas leaks in chamber.The present invention is connected through a screw thread
Fixed mode carries out the fixation of insulating boot and yoke, need not carry out brazing operation, desired technique is simpler, cost more
