Electric appliance and adapter
Provided are an electric appliance and a method of manufacturing the same, the electric appliance having a smaller size and a reduced overall weight by preventing a fluid from flowing into a space unrelated to a heating component in a state where the fluid fills its case. The electric appliance includes: a case including a first space and a second space communicated to each other; a first component disposed in the first space; a second component disposed in the second space; a connection portion electrically connecting the first component and the second component to each other; and a potting pattern including a resin material and formed in the first space.
1. An electric appliance comprising:
a case including a first space and a second space communicated to each other;
a first component disposed in the first space;
a second component disposed in the second space;
a connection portion electrically connecting the first component and the second component to each other, and extending from the second space to the first space;
a potting pattern including a resin material and formed in the first space;
a partition wall disposed between the first space and the second space in the case to separate the first space and the second space from each other, thereby preventing the potting pattern from flowing into the second space; and
a step portion formed on a boundary line between the first space and the second space by a difference in a width of the case in the first space between a width of the case in the second space,
wherein the partition wall is disposed on the step portion,
either a guide portion or a partition-wall guide portion is formed on at least one of the step portion and the partition wall, the guide portion being formed by making one surface of the step portion to be recessed and the partition-wall guide portion being formed by making a predetermined region of the partition-wall to be recessed inward, and
the connection portion is disposed between the step portion and the partition wall, by being disposed in at least one of the guide portion and the partition-wall guide portion.
2. The electric appliance of claim 1 , wherein a filling pattern having a lower specific gravity than the potting pattern is disposed in the second space.
3. The electric appliance of claim 2 , wherein the filling pattern includes a plurality of air bubbles.
4. The electric appliance of claim 1 , wherein the potting pattern has a viscosity of 50 gf/10 mm or more and 1000 gf/10 mm or less.
5. The electric appliance of claim 1 , wherein the case includes an observation window formed at a predetermined position in the first space for checking a filling amount of the potting pattern.
6. The electric appliance of claim 1 , wherein the case includes a fluid level indicator formed in the first space, the fluid level indicator having a scale shape and indicating an appropriate fluid level of the potting pattern.
7. The electric appliance of claim 1 , wherein the first component has a maximum heating temperature higher than the second component.
8. The electric appliance of claim 1 , wherein the partition wall includes an adhesive portion attached to the step portion.
9. The electric appliance of claim 1 , wherein the partition wall has a smaller thickness than the case.
10. The electric appliance of claim 1 , wherein the partition includes a reinforcing portion crossing a central portion of one surface of the partition wall.
11. The electric appliance of claim 1 , wherein a central portion of the partition wall has the convex curved surface.
12. The electric appliance of claim 1 , wherein a central portion of the partition wall protrudes to form a step.
13. An adapter comprising:
a case including a first space and a second space;
a heating component disposed in the first space;
a partition wall disposed between the first space and the second space in the case to separate the first space and the second space from each other and has a hole,
a potting pattern provided in the first space and consist of a resin material;
a connection portion extends from the second space to the first space through the hole and electrically connected to the heating component; and
a packing member interposed between the hole and the connection portion, and
wherein the partition wall prevents the potting pattern from flowing into the second space.
14. The adapter of claim 13 , wherein the potting pattern covers one surface of the partition wall.
15. The adapter of claim 13 , wherein the second space is filled with air.
16. The adapter of claim 13 , wherein a filling pattern including a foaming agent is formed in the second space.
