Problems solved by technology

However, this floor heating device is to arrange a plurality of plate heaters between the ground under the floor and the bottom plate to form a planar heating element. Especially if the planar heating element is to be set under the floor of an existing building, it is necessary to install the planar heating element on the ground floor. A plate-shaped heater is placed between the floor and a groove for wiring, so the construction cost is huge, which is an obstacle to popularization

Embodiment 1

[0026] exist Figure 1 ~ Figure 3 Among them, symbol 1 indicates a thin plate-shaped fuse body. The fuse main body 1 is provided with through-holes 1b, 1b for eyelet installation in the wide terminal portions 1a, 1a provided at both ends, and a length extending in the longitudinal direction is integrally provided between each terminal portion 1a, 1a. The fusing portion 2 with a narrow hole 2a, and a fire-resistant film 3 made of, for example, a mica film (trade name: mica adhesive tape) is used to paste and cover a part of each terminal portion 1a, 1a and the fusing portion 2, thus constituting the present invention. A short-circuit protection fuse (hereinafter simply referred to as a fuse) 4 according to the invention.

[0027] The fuse main body 1 is made of alloys of lead, tin, and copper, but not limited thereto. Phosphor bronze, other copper alloys, lead, tin, aluminum, etc. alone or alloys properly combined can be used as required. A mica film (trade name: mica adhesiv...

Embodiment 2

[0029] In addition, as a method of covering the melting portion 2 of the fuse 4 with the fire-resistant film 3, such as Figure 1 ~ Figure 3 As shown, the refractory film 3 can be cut into a thin rectangular shape and pasted from the up and down direction of the fuse part 2, or it can be Figure 4 As shown, the refractory film 5 is folded from the central part, and the fuse part 2 is covered from the upper and lower directions.

Embodiment 3

[0031] Additionally, if Figure 5 As shown, the refractory film 6 can also be wound on the fuse part 2 .

[0032] The material of the fuse main body 1 is an alloy of lead, tin, and copper as described above. The material thickness is an extremely thin product of about 0.08 mm. mm, the thickness of the refractory film is 0.15mm, its width is 12mm, the width of the fuse part is 2.35mm, its length is 20mm, the width of the long hole is 1.5mm, its length is 14mm, from the terminal part 1a, 1a to the fuse part The connecting parts 1c, 1c of 2 have a width of 5 mm and a length of 3.5 mm, and have appropriate strength so that they will not break or break when only pressure such as stepping on them from above is applied.

[0033] Figure 6 and Figure 7 Shown is the connection example when the above-mentioned fuse 4 according to the present invention is mounted on the plate heater constituting the planar heating element of the floor heating device, and the confirmation test of the ...

Abstract

The invention provides a fuse for short circuit protection and a floor heating device using the fuse. In particular, the fuse for short-circuit protection is thin, suitable for plate heaters of floor heating devices, and will not break or be damaged even if stepped on, and will not cause sparks to fly or catch fire when the fuse part is blown. The fuse for short-circuit protection is composed of: a thin-plate-shaped fuse body as a whole, which has terminal parts provided at both ends and a narrow fuse part provided between the terminal parts; heat-resistant film. The fuse is installed between a flat wire for supplying electric power to a plate-shaped heater constituting a planar heating element of an indoor floor heating device, and a copper wire connected to the flat wire inside the plate-shaped heater.

Description

technical field [0001] The present invention relates to a short-circuit protection fuse (fuse) particularly suitable for a heating circuit of a planar heating element of a floor heating device, and a floor heating device using the short-circuit protection fuse. Background technique [0002] In recent years, as a heating device for indoor heating, a floor heating device using a planar heating element composed of a plurality of plate heaters using electric heating has attracted attention because it is suitable for the human body and does not pollute the atmosphere. However, this floor heating device is to arrange a plurality of plate heaters between the ground under the floor and the bottom plate to form a planar heating element, especially if the planar heating element is to be set under the floor of an existing building, it is necessary to install the planar heating element on the ground floor. A plate-shaped heater is placed between the floor and a trench for wiring is inst...
