Abstract

A primary electrical fuse is attached to a printed circuit board. The primary electrical fuse comprises a first and second terminal, a fusible element disposed between the first and second terminals electrically linking the first terminal and the second terminal, and receiving tip sections located on the first and second terminals that receive a replacement electrical fuse to electrically connect the first and second terminals with a replacement fusible element.

Claims

1. A primary fuse attached to a printed circuit board comprising:

a first terminal and a second terminal;

a fusible element linearly mounted between the first terminal and the second terminal electrically linking the first terminal and the second terminal, wherein the first terminal, second terminal, and fusible element are portions of a unitary structure with each portion being disposed to have one of its major surfaces facing the same direction as the respective major surface of the other portions to form a flat unitary structure; and

receiving tip sections, located on the first terminal and the second terminal, for receiving a replacement fuse that electrically connects the first terminal to the second terminal with a replacement fusible element;

wherein at least one of the first terminal and second terminal has a mounting tip section defined by shoulder sections that mount to a printed circuit board and has a major surface facing the same direction as a major surface of the fusible element.

2. The primary fuse as claimed in claim 1, wherein the receiving tip sections receive a replacement fuse having fork-shaped connectors.

3. The primary fuse as claimed in claim 1, wherein the mounting tip section is wedge-shaped and has a width at least at one point that is substantially identical to an opening in the printed circuit board.

4. An electric fuse assembly attached to a printed circuit board comprising:

a primary fuse having a first terminal and a second terminal;

a fusible element disposed between the first terminal and the second terminal electrically linking the first terminal and the second terminal, wherein the first terminal, second terminal, and fusible element are portions of a unitary structure with each portion being disposed to have one of its major surfaces facing the same direction as the respective major surface of the other portions to form a flat unitary structure;

a replacement fuse having a third terminal and a fourth terminal wherein the third terminal and the fourth terminal each have fork-shaped connectors;

a replacement fusible element linearly disposed between a tine of the fork-shaped connector of the third terminal and a corresponding tine of the fork-shaped connector of the fourth terminal electrically linking the third terminal and the fourth terminal, wherein the replacement fusible element and the fork-shaped connectors are portions of a second unitary structure; and

receiving tip sections, located on the primary fuse, receiving the replacement fuse that electrically connects the first terminal to the second terminal with the replacement fusible element, wherein the fusible element is positioned linearly with respect to the first terminal and the second terminal and the replacement fuse is offset from the fusible element.

5. An electric fuse assembly as claimed in claim 4, wherein at least one of the first terminal and second terminal has a mounting tip section, defined by shoulder sections, extending through an opening in a printed circuit board and attaching to the printed circuit board via a electrically-conductive connection.

6. An electric fuse assembly as claimed in claim 4, wherein the replacement fuse has at least one socket that receives and electrically connects the replacement fuse to the primary fuse.
