る）に関する。DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a display fusible body fixed to one band plate is guided through the other band plate, and is fixed to a spring plate by applying an initial tension to the spring plate. The present invention relates to a low-voltage, large-capacity fuse with a spring plate display type display (hereinafter abbreviated as NH fuse) that is visually displayed by changing its state.

ズを得ることにある。When no additional functionality is required, spring plate indicators have the advantage of being more economical to manufacture and assemble than conventional pin indicators. The object of the invention is to obtain a particularly reliable NH fuse with a spring plate indicator which can be produced particularly economically.

内されることにより達成される。To this end, according to the invention, the spring plate is formed from two mutually overlapping legs, a bent and interconnected base leg and a narrow display leg, and a flat leg. A slit is formed in the curved part extending to the end of the leg and the end of the leg, and the display fusible body is fixed to the display leg and drawn outward through the slit in the curved part, and guided from the slit in the leg end through the hole in the band plate. This is achieved by

が溶断したかどうかの信頼性ある表示が保証される。NH fuses with such a 'springboard indicator' are mechanically conditioned on the one hand and tensioned on the indicator fusible body by guiding it in a special way onto the springboard indicator on the other hand. Since the force is removed, a reliable indication of whether the fuse has blown is ensured.

広い透孔をおおうようになっている。Such NH fuses are also particularly reliable when installed in installations, since no parts of the indicator fall out when the fuse is activated. In this case, the slits at the leg ends of the display legs are used for guiding and positioning the display fusible body. According to one embodiment of the NH fuse:
A strip that fits the rivet hole in the base leg is extruded from the strip that supports the spring plate display, and the end of the slit in the base leg is almost as wide as the strip except for the diameter of the display fusible body. It is designed to cover the hole.

ことがないから、信頼性のある運転における経済的な組
立によれば、表示用可溶体は表示用脚部に溶接される。This eliminates the need for special packings, which would normally be required in the case of through holes in the strip supporting the spring plate display. Such a hole cannot be formed arbitrarily finely due to the thickness of the strip, and it is necessary to prevent the arc-extinguishing filler sand of the NH fuse from coming out of the hole.
This spring plate indicator therefore also serves to close the through hole at the same time. In this case, it is preferable that the weave of the slit in the base leg be tapered in a V-shape and have a small rounded bottom. According to an economical assembly with reliable operation, the display fusible is welded to the display leg, since no parts fall off during operation of the display fusible.

ね板からなっている。The disconnection of the fuse is indicated by a display device consisting of a spring plate indicator 4 and a display fusible body 5. The display fusible body 5 is fixed to the strip plate 6 by a sleeve 7, and the sleeve 7 also serves to close the arc-extinguishing sand filling port in a conventional manner. The display fusible body is guided through another strip 8 and through a hole 9 and is fixed to one leg of the spring plate display 4. The spring plate display shown in FIG. 2 consists of a spring plate forming two overlapping legs, a base leg 10 and a display leg 11.

A slit 13 is formed in the curved portion 12 until it reaches a flat leg. Similarly, a slit 14 is provided at the end of the leg.
and 15 are provided, and the bottoms of these slits are aligned in the assembled state. The display fusible body 5 is welded to the inside of the display leg 11 to form the slit 1.
3 and is pulled out to the outside through slits 15 and 14 in the legs and through hole 9.

A rivet 17 is provided on the base leg 10 of the spring plate indicator 4 and fits into the pet hole 16, so that the inner weave of the slit 4 of the base leg 10 is connected to the display fusible body 5, as shown in FIG. If the wide opening 9 of the strip 8 is substantially covered except for the diameter of , the usual additional packing of the opening 9 can be omitted. As shown in FIG. 6, it is advantageous if the inner end of the slit in the base leg is tapered in a V-shape and formed with a small roundness.
