The iron cup is the tubular structure of both ends open, and the iron core sleeve is the tubular structure of upper end open and lower end closed, the iron
The upper end open of core retainer plate cylinder is sealedly attached to the bottom plate center, and the surrounding of the bottom plate and the lower ending opening of iron cup are sealed
It is fixedly connected, the upper port and the upper end cover of the shell body of the iron cup are sealedly and fixedly connected；The direct current device in sealing contact
Coil block be arranged at that the iron core sleeve is outer and shell body in, other in addition to coil block of the direct current device in sealing contact
Part is arranged in the iron core sleeve, bottom plate, iron cup and the sealing space of upper end cover formation.
As further improvement of the utility model, pass through between the lower ending opening of the surrounding of the bottom plate and iron cup
Welded seal is fixedly connected.
As further improvement of the utility model, on the outside of the upper port outside of the iron cup and the upper end of iron cup
The upper port of iron cup is sealed provided with one layer of epoxy resin sealant between the shell body, the upper end cover is covered on
Outside the epoxy resin sealant.
As further improvement of the utility model, projection is extended inwardly to form in the middle part of the shell body, the projection is supported
Tightly on the lateral surface of iron cup, the epoxy resin sealant is extended downward at the raised position.
As further improvement of the utility model, the binding post of the coil block is drawn from the bottom end cover.
The beneficial effects of the utility model are：The sealing device of direct current device in sealing contact uses split-type structural, by iron
Cup, bottom plate and iron core sleeve are assemblied together according to certain order, are then welded together using the mode of welding, form one
It is sealedly overall, and coil block is arranged on the outside of sealing device, reaches the effect of effectively shielding pollution sources, so as to protect
The cleanliness factor of sealed environment is held, does not allow sealed environment to be contaminated, so as to improve the electrical performance indexes of product.
Brief description of the drawings
