【考案の詳細な説明】[Detailed description of the invention]

【考案の属する技術分野】[Technical field to which the invention belongs]

本考案は、チップ型ヒューズに関するものである。 The present invention relates to a chip type fuse.

【0002】[0002]

【従来の技術】[Prior art]

ヒューズは規定以上の電流が流れると、加熱によりヒューズに取り付けられた 可溶合金が溶断することにより、電気回路を自動的に断つものである。 従来のチップ型ヒューズは図4に示すように基板(40)の対向している両端 それぞれにT形銅極プレート(45)が配設されると共に、二つの銅極プレート (45)の間にヒューズプレート(50)が接続されるものである。 The fuse automatically cuts off the electrical circuit when the fusible alloy attached to the fuse melts due to heating when a current exceeding the specified value flows. In the conventional chip type fuse, as shown in FIG. 4, a T-shaped copper electrode plate (45) is provided at each of opposite ends of the substrate (40), and between the two copper electrode plates (45). The fuse plate (50) is to be connected.

【考案が解決しようとする課題】[Problems to be solved by the invention]

しかし、このようなチップ型ヒューズにおけるヒューズプレートは製造工程中 に不要な成分が混入したり、スクリーン印刷においては厚みの均一性を達成しに くく、表面が凹凸に形成されてしまったりするので、電気抵抗値などの品質管理 が困難であった。このようなチップ型ヒューズを使用すると、品質のばらつきに より、電流の規定値に大きな誤差が出てしまい、所望のタイミングで電気回路を 断つことができない場合があった。 However, in the fuse plate of such a chip type fuse, unnecessary components are mixed during the manufacturing process, and it is difficult to achieve uniform thickness in screen printing, and the surface is formed unevenly. Quality control such as electrical resistance was difficult. When such a chip-type fuse is used, there is a case where a large error occurs in a specified value of a current due to a variation in quality, and an electric circuit cannot be cut off at a desired timing in some cases.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

本考案のチップ型ヒューズは、基板(30)の対向している両端それぞれに銅 極プレート(35)が配設されたチップ型ヒューズであって、二つの銅極プレー ト(35)の間に少なくとも一本のヒューズワイヤ(10)が並列に接続される と共に、このヒューズワイヤ(10)の上面に、絶縁保護プレート(20)が設 けられたことを特徴とする。 The chip-type fuse of the present invention is a chip-type fuse in which a copper electrode plate (35) is provided on each of opposite ends of a substrate (30), and is provided between two copper electrode plates (35). At least one fuse wire (10) is connected in parallel, and an insulating protection plate (20) is provided on the upper surface of the fuse wire (10).

【0005】 本考案は上記の課題を解決するものであり、ヒューズプレートの代わりに、ヒ ューズワイヤを利用して、電気抵抗値などの品質を管理しやすくすることにより 、比較的精密な可溶合金が実現できるので、過電流をより確実に検知することが できると共に、保護プレートを設けることによりヒューズワイヤの損傷を防止す ることができる。[0005] The present invention solves the above-mentioned problems, and uses a fuse wire instead of a fuse plate to make it easier to control the quality of electric resistance and the like, so that a relatively precise fusible alloy can be obtained. Therefore, overcurrent can be more reliably detected, and damage to the fuse wire can be prevented by providing a protection plate.

【考案の実施の形態】[Embodiment of the invention]

以下、添付図面を参照して本考案の好適な実施の形態を詳細に説明する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

【0008】 図1乃至図3に示すように、本考案のチップ型ヒューズは、基板(30)の対 向している両端それぞれに銅極プレート(35)が配設されると共に、二つの銅 極プレート(35)の間に、ボンディング加工により、ヒューズワイヤ(10) が四本並列状に接続され、これらのヒューズワイヤ(10)の上面に、絶縁保護 プレート(20)が接着される。 従って、過電流が銅極プレート(35)を流れると、各ヒューズワイヤ(10 )が電流の規定値に応じてタイミングよく溶断するので、電気回路を自動的に切 断し、保護することができる。As shown in FIGS. 1 to 3, the chip type fuse of the present invention has a copper electrode plate (35) disposed on each of opposite ends of a substrate (30) and two copper electrodes. Four fuse wires (10) are connected in parallel between the pole plates (35) by bonding, and an insulating protection plate (20) is adhered to the upper surfaces of these fuse wires (10). Therefore, when an overcurrent flows through the copper plate (35), each fuse wire (10) is blown at a proper timing according to the specified value of the current, so that the electric circuit can be automatically cut and protected. .

【考案の効果】[Effect of the invention]

1.本考案に係るチップ型ヒューズは、ヒューズワイヤの材料使用量が低いの で、コストダウンにつながる。 2.ヒューズワイヤの体積は非常に小さいので、不要な成分の混入の恐れが低 くなり、材質の均一性などの品質管理がしやすくなると共に、ヒューズワイヤの 電気抵抗値を精密に管理できるので、確実に過電流を検知することができる。 3.絶縁保護プレートを設けることにより、ヒューズワイヤの損傷を防止でき るので、チップ型ヒューズの寿命を伸ばすことができると共に、スムーズに電気 回路を作動させることができる。 1. The chip type fuse according to the present invention uses less material for the fuse wire, which leads to cost reduction. 2. Since the volume of the fuse wire is very small, the risk of mixing of unnecessary components is reduced, quality control such as uniformity of materials is easy, and the electrical resistance value of the fuse wire can be precisely controlled. Overcurrent can be detected. 3. By providing the insulating protection plate, the damage of the fuse wire can be prevented, so that the life of the chip type fuse can be extended and the electric circuit can be operated smoothly.
