Abstract

A housing for an electrical overload protection cable assembly having a first cable, a second cable, a fusible link, and a protective housing. The protective housing has a first housing member and a second housing member. The first and second housing members each have a first end portion and a second end portion. The first and second housing members are coupled to form the protective housing having a channel extending from the first end to the second end. A first rib extends from the protective housing into the channel, and a second rib extends from the protective housing into the channel. The second rib is transverse to the first rib.

Claims

1. A protective housing for a fusible link and cable assembly comprising:

a first housing member having a first end portion and a second end portion, a second housing member having a first end portion and a second end portion, the first and second housing members coupled to form the protective housing having a channel extending from the first end portion to the second end portion thereof, wherein first and second ribs extend from the first end portion of one of either the first housing member or the second housing member, the second rib being transverse to the first rib, and wherein first and second ribs extend from the second end portion of the other of either the first housing member or the second housing member, the second rib being transverse to the first rib.

2. The housing of claim 1, further comprising a shoulder extending from the first housing member, and a groove in the second housing member, the shoulder of the first housing member mating with the groove of the second housing member when the first and second housing members are coupled.

3. The housing of claim 2, further comprising a groove in the first housing member, and a shoulder extending from the second housing member, the shoulder of the second housing member mating with the groove of the first housing member when the first and second housing members are coupled.

4. The housing of claim 1, wherein each of the first ribs extend axially from the protective housing, and wherein each of the second ribs extend substantially perpendicular to the first ribs.

5. A protective housing for a fusible link and cable assembly comprising:

a first housing member having a first end portion and a second end portion, and a shoulder extending from the first housing member;

a second housing member having a first end portion and a second end portion, the second housing member having a groove therein;

wherein the shoulder of the first housing member mates with the groove in the second housing member when the first and second housing members are connected to form the protective housing, wherein a channel is formed in the protective housing between the first and second housing members, wherein the first housing member has first and second ribs extending from the first end portion of the first housing member into the channel, the first rib of the first housing member being transverse to the second rib of the first housing member, and wherein the second housing member has first and second ribs extending from the second end portion of the second housing member into the channel, the first rib of the second housing member being transverse to the second rib of the second housing member.

6. The protective housing of claim 5, further comprising first and second ribs extending from the first end portion and the second end portion of the first housing member into the channel, the first rib extending from the second end portion of the first housing member being transverse to the second rib extending from the second end portion of the first housing member;

and,

first and second ribs extending from the first end portion and the second end portion of the second housing member into the channel, the first rib extending from the second end portion of the second housing member being transverse to the second rib extending from the second end portion of the second housing member.

7. The protective housing of claim 5, further comprising a shoulder extending from the second housing member, and a groove in the first housing member, wherein the shoulder and groove of the first housing member mate with the groove and shoulder, respectively, of the second housing member when the first and second housing members are connected.

8. The protective housing of claim 5, wherein the shoulder extends adjacent a side of the first housing member, and wherein the groove extends adjacent a side of the second housing member.

9. The protective housing of claim 5, wherein the first housing member is an identical component as the second housing member.

10. The protective housing of claim 5, wherein the first housing member is fixedly connected to the second housing member.

11. A protective housing for a fusible link and cable assembly comprising:

a pair of housing members, each housing member having a first end portion, a second end portion, and an intermediate section therebetween, the first end portion having a first cavity, the second end portion having a second cavity, and the intermediate section having an intermediate cavity, wherein the intermediate cavity has a greater volume than the first and second cavities, wherein a first rib protrudes from each housing member into the first cavity, wherein a second rib protrudes from each housing member into the second cavity, the first rib being transverse to the second rib, wherein each housing member has a groove adjacent a side thereof and a shoulder adjacent an opposing side thereof, and wherein the housing members connectedly mate to form the protective housing, the first, second, and intermediate cavities of the housing members forming a channel from a first end of the protective housing to a second end of the protective housing.

12. The protective housing of claim 11, wherein the protective housing has a longitudinal axis extending from the first end of the protective housing to the second end of the protective housing, the first rib of the each housing member extending about portion of the longitudinal axis of the protective housing.

13. The protective housing of claim 12, wherein the second rib of each housing member, respectively, extends substantially perpendicular to the first rib.

14. The protective housing of claim 11, wherein the housing members are fixedly connected to each other.

15. A protective housing for a fusible link and cable assembly comprising:

a housing member having a first end portion, a second end portion, and a channel extending from the first end portion to the second end portion thereof, wherein a plurality of first ribs extend from the housing member about a portion of a longitudinal axis of the housing member, at least one of the first ribs extending adjacent the first end portion of the housing member and at least another one of the first ribs extending adjacent the second end of the housing member, the longitudinal axis of the housing member extending from the first end of the housing member to the second end of the housing member, and wherein a plurality of second ribs extend from the housing member, the second ribs being transverse to the first ribs.
