Abstract

Claims (29)

1. A housing for use in an automobile electrical power distribution system for supporting electronic components, the housing comprising:

a first housing portion having a main portion; and

a retainer extending from the main portion, the retainer being adapted to cooperate with a first printed circuit board element to hold the first printed circuit board element in spaced relation to the main portion and hold a second printed circuit board element in spaced relation to the first printed circuit board element,

wherein said retainer is integral with said first housing and includes a post having an enlarged head axially spaced from the main portion, said head including flexible prongs having a width greater than the width of a hole in the first printed circuit board, and wherein said head is configured to resiliently snap through the hole in the first printed circuit board element and expand outwardly to hold the first printed circuit board element in spaced relationship to the main portion.

2. The housing of claim 1 , further comprising one or more printed circuit board edge supports extending from the first housing portion, the retainer being adapted to pull the first printed circuit board element against the one or more edge supports, the one or more edge supports holding the first printed circuit board element in spaced relation to the main portion.

3. The housing of claim 1 , further comprising one or more support pads extending from the first housing portion, the retainer being adapted to pull the first printed circuit board element against the one or more support pads, the one or more support pads holding the first printed circuit board element in spaced relation to the main portion.

4. The housing of claim 1 , further comprising one or more bi-passing edge supports, which pass through keyways in the first printed circuit board element and engage the second printer circuit board element to hold the second printed circuit board element in spaced relation to the first printed circuit board element.

5. A junction box housing for use in an automobile electrical power distribution system; the junction box comprising:

a first housing portion and a second housing portion adapted to cooperate with the first housing portion to form an enclosure for supporting a printer circuit board;

at least one retainer extending from the first housing portion; and

at least one support element extending from the first housing portion, the retainer being configured to cooperate with a first printed circuit board element and pull the first printed circuit board element toward the support element, which supports the first printed circuit board element in spaced relation to the first housing portion, the retainer further being adapted to hold a second printed circuit board element in spaced relation to the first printed circuit board element,

wherein said retainer is integral with said first housing and includes a post having an enlarged head axially spaced from the main portion, said head including flexible prongs having a width greater than the width of a hole in the first printed circuit board, and wherein said head is configured to resiliently snap through the hole in the first printed circuit board element and expand outwardly to hold the first printed circuit board element in spaced relationship to the main portion.

6. The junction box of claim 5 , wherein the at least one support element includes one or more printed circuit board edge supports for supporting an edge of the first printed circuit board element in spaced relation to a main portion of the first housing portion.

7. The junction box of claim 5 , wherein the at least one support element support pads for supporting the first printed circuit board element in spaced relation to a main portion of the first housing portion.

8. The junction box of claim 5 , further comprising one or more bi-passing edge supports extending from the first housing portion, the one or more bi-passing edge supports are adapted to pass through keyways in the first printed circuit board element and engage a second printer circuit board element to hold the second printed circuit board element in spaced relation to the first printed circuit board element.

9. The junction box of claim 8 , further comprising one or more bi-passing edge supports extending from the second housing portion and axially offset relative to the one or more bi-passing edge supports extending from the first housing portion, the one or more bi-passing edge supports each extending from the second housing portion are adapted to pass through a keyway in the second printed circuit board element and engage the first circuit board element to hold the first printed circuit board element in spaced relation to the second printed circuit board element.

10. A control module for use in an automobile electrical power distribution system, the control module comprising:

a housing comprised of a first housing portion and a second housing portion that is adapted to be coupled to the first housing portion;

at least one first printed circuit element within the housing;

at least one support element extending from the first housing portion; and

at least one retainer extending from the first housing portion and cooperating with the first printed circuit board element to pull the first printed circuit board element toward the support element, which holds the first printed circuit board element in spaced relation to the housing,

wherein said retainer is integral with said first housing and includes a post having an enlarged head axially spaced from the main portion, said head including flexible prongs having a width greater than the width of a hole in the first printed circuit board, and wherein said head is configured to resiliently snap through the hole in the first printed circuit board element and expand outwardly to hold the first printed circuit board element in spaced relationship to the main portion.

11. A control module of claim 10 , further comprising:

a second printed circuit board element within the housing;

at least one support element extending from the second housing portion, wherein the support elements are edge supports;

at least one bi-passing edge support extending from the first housing portion through a keyway in the first printed circuit board element and engaging the second printer circuit board element to hold the second printed circuit board element against the edge support extending from the first housing portion and away from the first printed circuit board element; and

at least one bi-passing edge support extending from the second housing portion through a keyway in the second printed circuit board element and engaging the first printer circuit board element to hold the first printed circuit board element against the edge support extending from the second housing portion and away from the first printed circuit board element, and wherein the retainer has a head that passes through a hole in the first printed circuit board element and engages the second printed circuit board element to hold the second printed circuit board element in spaced relation to the first printed circuit board element.

12. The control module of claim 11 , wherein the keyway in the first printed circuit board element does not axially align with the keyway in the second printed circuit board element, and the bi-passing edge support extending from the first housing portion does not axially align with the bi-passing edge support extending from the second housing portion.

13. The control module of claim 11 , wherein the first printed circuit board element and the second printed circuit board element are joined together in overlapping orientation by at least one rolled end to form a rolled printed circuit board element.
