Fusible electrical connector

Claim 2

A fusible electrical connector assembly comprising a sheet metal terminal of one-piece construction having a contact end portion, a cable attachment end portion and an intermediate fuse portion which is the sole terminal portion connecting the contact end portion to the cable attachment end portion, and a housing having a fuse chamber in which the intermediate fuse portion of the terminal is disposed, said chamber in part being defined by first and second spaced walls of the housing, each of which has a slot opening extending therethrough, said contact end portion of the terminal extending into the chamber through the slot opening in said first wall and having conformations on the opposite sides of said first wall, said cable attachment portion extending into said chamber through the opening in said second wall and having conformations on the opposite sides of said second wall, and said conformations of the end portions of the terminal cooperating with the respective spaced walls to retain the respective end portions of the terminal in assembly with the housing upon failure of the intermediate fuse portion due to an excessive electric current.

Claim 3

A fusible electrical connector assembly comprising a sheet metal terminal of one-piece construction having a contact end portion, a cable attachment end portion comprising a crimp barrel and an intermediate fuse portion which is the sole terminal portion connecting the contact end portion to the cable attachment end portion, and a housing having a longitudinal fuse chamber in which the intermediate fuse portion of the terminal is disposed, said chamber in part being defined by first and second spaced walls of the housing, each of which has a slot opening extending therethrough, said contact end portion of the terminal having a bridge portion extending into the fuse chamber through the slot opening in said first wall and upright tabs at the end of the bridge portion disposed inside the fuse chamber, said cable attachment portion having a bridge portion extending into said fuse chamber through the slot opening in said second wall and upright tabs at the end of the bridge portion disposed inside the fuse chamber, said tabs cooperating with said first and second walls to locate said fuse portion longitudinally in said fuse chamber, said contact end portion having a conformation on the opposite side of said first wall from the upright tabs at the end of its bridge portion to provide two-way retention of the contact end portion with the housing upon failure of the intermediate fuse portion due to an excessive electric current, and said cable attachment end portion having a conformation on the opposite side of the second wall from the upright tabs at the end of its bridge portion to provide two-way retention of the cable attachment end portion upon failure of the intermediate fuse portion.

Claim 4

A fusible electrical connector assembly comprising a sheet metal terminal of one-piece construction having a contact end portion, a cable attachment end portion comprising a crimp barrel and an intermediate fuse portion which is the sole terminal portion connecting the contact end portion to the cable attachment end portion, and a housing having a longitudinal fuse chamber in which the intermediate fuse portion of the terminal is disposed, said chamber in part being defined by first and second spaced walls of the housing, each of which has a slot opening extending therethrough, said contact end portion of the terminal having a bridge portion extending into the fuse chamber through the slot opening in said first wall and upright tabs at the end of the bridge portion disposed inside the fuse chamber, said cable attachment portion having a bridge portion extending into said fuse chamber through the slot opening in said second wall and upright tabs at the end of the bridge portion disposed inside the fuse chamber, said tabs cooperating with said first and second walls to locate said fuse portion longitudinally in said fuse chamber, said contact end portion having a conformation on the opposite side of said first wall from the upright tabs at the end of its bridge portion to provide two-way retention of the contact end portion with the housing upon failure of the intermediate fuse portion due to an excessive electric current, and said cable attachment end portion having a conformation on the opposite side of the second wall from the upright tabs at the end of its bridge portion to provide two-way retention of the cable attachment end portion upon failure of the intermediate fuse portion.

Claim 5

The fusible electrical connector as defined in claim 2 wherein the tabs and conformations of the end portions cooperate with the first and second walls to maintain a spacing between the ends of the remnants of the fuse portion upon failure thereof to prevent contact and current flow after the fuse portion has blown.

Claim 6

The fusible electrical connector as defined in claim 2 wherein the bridge portion of the contact end portion is a bent end of a strap and the strap is the conformation of the contact end portion.

Claim 7

The fusible electrical connector as defined in claim 2 wherein the crimp barrel is the conformation of the cable attachment end portion.

Claim 8

The fusible electrical connector as defined in claim 2 wherein the contact end portion includes a strap which provides the conformation and a bent end of the strap which provides the bridge portion thereof and wherein the crimp barrel of the attachment end portion is perpendicular to the bridge portion thereof to provide the conformation of the attachment end portion.

Claim 9

The fusible electrical connector as defined in claim 2 wherein the housing includes a second chamber which communicates with the fuse chamber through the slot opening in the second wall and wherein the crimp barrel is disposed in the second chamber.
