Abstract
The body component and the protector component are inserted into the through hole of the end face plate. The protector component is disposed, in the through hole, at a place closer to the outer surface of the end face plate than the body component is. The body component guides a tail cable into the internal space of the pressure-resistant housing main body. The protector component protects the tail cable. The nut fixes the protector component to the end face plate. The elastic member is attached to the end face plate so as to cover the boundary part between the protector component and the nut. The insulating liquid is charged in the space between the elastic member and the protector component.
Claims14
A feedthrough structure comprising:
- a body component inserted in a through hole formed in an end face plate of a pressure-resistant housing, and configured to guide a tail cable into an internal space of the pressure-resistant housing;
- a protector component disposed in the through-hole at a place closer to an outer surface of the end face plate than the body component is, and configured to protect the tail cable;
- a nut configured to fix the protector component to the end face plate;
- a first elastic member attached to the end face plate so as to cover a boundary part between the protector component and the nut;
- and
- an insulating liquid charged in a space between the first elastic member and the protector component.
An underwater apparatus comprising:
- a pressure-resistant housing main body with an opening formed at least one end thereof, the pressure-resistant housing main body including an internal space;
- at least one end face plate with a through hole formed therein, disposed in the opening;
- an internal unit disposed in the internal space;
- and
- a feedthrough structure inserted in the through-hole, wherein
- the feedthrough structure comprises:
- a body component inserted in the through-hole of the end face plate, and configured to guide a tail cable into an internal space of the pressure-resistant housing;
- a protector component disposed in the through-hole at a place closer to an outer surface of the end face plate than the body component is, and configured to protect the tail cable;
- a nut configured to fix the protector component to the end face plate;
- a first elastic member attached to the end face plate so as to cover a boundary part between the protector component and the nut;
- and
- an insulating liquid charged in a space between the first elastic member and the protector component.
