Abstract
A fusible link receptacle that, when a fusible link is inserted in the receptacle at an inclined angle, prevents both damage to tab connectors and faulty connections between terminals in the fusible link and the tab connectors. Tab connectors extend from internal circuits into the internal region of the fusible link receptacle, and a rib is formed on the internal surface of the perimeter wall and extends to a point above the leading edges of the tab connectors. Should an attempt be made to insert the fusible link into the fusible link receptacle at an inclined angle, the rib makes interfering contact with the lower edge of the fusible link to prevent further insertion.
Claims14
A fusible link receptacle for an electrical connector box, said fusible link receptacle provided on an exterior surface of an electrical connector box case to accommodate the selectable insertion of a short first fusible link or a tall second fusible link therein, said fusible link receptacle comprising:
- a perimeter wall surrounding a base plate and forming an interior region of said fusible link receptacle;
- tab connectors projecting from the electrical connector box and into said interior region of said fusible link receptacle, said tab connectors forming a portion of internal circuits within the electrical connector box to connect to one of said first and second fusible links;
- and
- a rib provided on an interior surface of said perimeter wall and extending to a point above top edges of said tab connectors, wherein said rib is configured to be inserted into a channel provided within an external wall of said first and second fusible links, said rib having substantially the same width as the channels within the external wall of said first and second fusible links, and said rib having a depth projecting from the interior surface of said perimeter wall sufficient to be inserted into the channel within the external wall of said first and second fusible links;
- wherein said rib is positioned opposite to and between said tab connectors that project into the interior region of said fusible link receptacle.
In combination, a fusible link and a fusible link receptacle for an electrical connector box, the fusible link receptacle provided on an exterior surface of an electrical connector box case to accommodate the selectable insertion of a short first fusible link or a tall second fusible link therein, said fusible link receptacle and one of said first and second fusible links comprising:
- one of a short first fusible link and a tall second fusible link;
- a perimeter wall surrounding a base plate and forming an interior region of said fusible link receptacle;
- tab connectors projecting from the electrical connector box and into said interior region of said fusible link receptacle, said tab connectors forming a portion of internal circuits within the electrical connector box to connect to one of said first and second fusible links;
- a rib provided on an interior surface of said perimeter wall and extending to a point above top edges of said tab connectors;
- and
- a channel provided within an external wall of said first and second fusible links, said rib being inserted into said channel, said rib having substantially the same width as the channels within the external wall of said first and second fusible links, and said rib having a depth projecting from the interior surface of said perimeter wall sufficient to be inserted into the channel within the external wall of said first and second fusible links;
- wherein said rib is positioned opposite to and between said tab connectors that project into the interior region of said fusible link receptacle.
