Problems solved by technology

However, when the FET switch is damaged due to a short circuit due to some reason, when a momentary large current such as a lightning surge is applied, or when the output voltage drops abnormally due to the life of the battery cell, or an abnormally large voltage is output conversely, it is necessary to Protect battery packs and electronic equipment from accidents such as fire

Embodiment Construction

[0053] Hereinafter, the present embodiment will be described in detail with reference to the drawings. In addition, this invention is not limited only to the following embodiment, It goes without saying that various changes can be made in the range which does not deviate from the summary of this invention. In addition, the drawings are only schematic diagrams, and ratios of dimensions and the like may differ from actual ones. Specific dimensions and the like should be judged in consideration of the following description. In addition, it is a matter of course that the drawings also include parts in which mutual dimension relations and ratios are different.

[0054] The present invention is applicable, for example, to Figure 1A , Figure 1B The short circuit element 100 of the structure shown. Figure 1A Showing a top view of the short circuit element 100, Figure 1B show Figure 1A The view in the arrow direction of the A-A line section of the short-circuit element 100 in ....

Abstract

A structure is provided wherein a fusible conductor (5) for short circuiting a short circuit portion (20) in a signal path is separated from a fusible conductor (6) of a fuse portion (30) in a current-running path of a heating portion (10), and, between the fusible conductors (5, 6) of the short circuit portion (20) and the fuse portion (30), a difference arises in the amount of heat for the heating effect caused by running current through the heating portion (10). This structure guarantees a relationship in which the melting action time for the fusible conductor (5) of the short circuit portion (20) is always quicker than the blow out action time for the fusible conductor of the fuse portion (30), thereby ensuring a stable short circuiting action for a short circuit element (100). Provided in this manner is a short circuit element whereby reliable short circuiting action and stabilization of conduction resistance after short circuiting are achieved, allowing a bypass path to be formed with certainty; also provided is a compensation circuit using this short circuit element.

Description

technical field [0001] The present invention relates to a short-circuit element provided with a heating resistor and a fuse element on a substrate, and a compensation circuit for eliminating only abnormal parts in electronic equipment using the short-circuit element. This application claims priority based on Japanese Patent Application No. 2014-223363 for which it applied in Japan on October 31, 2014, By referring this application, it is used in this application. Background technique [0002] Conventionally, in an LED lighting device using a plurality of light-emitting diodes (LED: Light Emitting Diode) as a light source, even if some light-emitting diodes fail, it can be used as a lighting device without hindrance. All of the elements are connected in parallel with a short-circuit element, and when the LED is abnormal, the short-circuit element is short-circuited with a predetermined voltage, so that the LEDs other than the failed LED can continue to emit light (for example...
