Housing with air chamber for battery monitor system and method for manufacturing same
A housing is described that may include a main portion having at least one wall defining an opening that may have a perimeter. The at least one wall may have a rib and an inner wall extending therefrom about the perimeter of the opening. The inner wall may have an air relief slot formed therein. The housing may further include a cover. The cover may have an edge defining a perimeter. The cover may include a rib extending from the edge about the perimeter of the cover. The main portion rib, the inner wall and the cover rib may cooperate for attachment of the cover to the main portion and to define an air chamber between the cover rib and the inner wall.
1. A housing comprising:
a main portion comprising at least one wall defining an opening having a perimeter, the at least one wall having a rib and an inner wall extending therefrom about the perimeter of the opening, the inner wall having an air relief slot formed therein; and
a cover having an edge defining a perimeter, the cover comprising a rib extending from the edge about the perimeter of the cover;
wherein the main portion rib, the inner wall and the cover rib are configured to cooperate for attachment of the cover to the main portion and to define an air chamber between the cover rib and the inner wall.
2. The housing of claim 1 wherein the main portion is adapted to receive an electronic component, the component configured for attachment to a battery terminal connector.
3. The housing of claim 1 wherein the air chamber facilitates vibration of the cover relative to the main portion to attach the cover to the main portion by friction welding.
4. The housing of claim 3 wherein the inner wall is configured to engage an inner surface of the cover to define a friction welding area.
5. The housing of claim 1 wherein the air chamber communicates with an interior of the housing via the air relief slot.
6. The housing of claim 1 wherein the air chamber inhibits water ingress into the housing.
7. The housing of claim 1 wherein the main portion and the cover comprise the same plastic material.
8. A housing comprising:
a sidewall extending from a base and defining an opening having a perimeter, the sidewall having a rib and an inner wall extending therefrom about the perimeter of the opening;
wherein the sidewall is adapted to cooperate with a cover to define a housing chamber, the cover having an edge defining a perimeter and comprising a rib extending from the edge about the perimeter of the cover, wherein the cover rib and inner wall define an air chamber therebetween, and wherein the air chamber facilitates vibration of the cover relative to the inner wall to attach the cover to the inner wall by friction welding.
9. The housing of claim 8 further comprising a cover adapted to cooperate with the sidewall for attachment of the cover to the sidewall to define the housing chamber.
10. The housing of claim 8 wherein the air chamber communicates with the housing chamber via an air relief slot formed in the inner wall.
11. The housing of claim 8 wherein the inner wall is configured to engage an inner surface of the cover to define a friction welding area.
12. The housing of claim 8 wherein the sidewall and base are adapted to receive an electronic component, the component configured for attachment to a battery terminal connector.
13. The housing of claim 8 wherein the air chamber inhibits water ingress into the housing chamber.
14. The housing of claim 9 wherein the sidewall and the cover comprise the same plastic material.
