Abstract
A fuse plug, in particular for terminal blocks in control, regulation and power supply systems, essentially comprising a housing, a fuse-element which is fused upon overshooting of a specific current intensity, contact elements and a display element. Reliable protection against surge voltages is provided. The device ensures that production can be automated with low costs by virtue of the housing (1) being formed from two flat holding halves (2, 3) that can be folded by means of a film hinge 4. The division of the housing is provided in the plane of the plug contacts (5, 6). The fuse-element (7), plug contacts (5, 6) and a display device (19) with a signalling element (15) are arranged in one holding half (2) of the housing (1).
Claims7
A fuse plug, comprising:
- a housing having two substantially flat holding halves and a film hinge joining one of said substantially flat holding halves with the other of said flat holding halves, said two substantially flat holding halves and said film hinge being formed of a single molded piece, said folding halves being foldable by means of said film hinge;
- a fuse-element which is fused upon overshooting of a specific current intensity;
- contact elements including plug contacts, said contact elements being electrically connected by said fuse-element for electrical transmission form one of said contact elements to another of said contact elements in a non-fused state of said fuse element;
- and
- a display device with a signaling element, a division of the housing forming said two flat holding halves being provided in a plane of said plug contacts, said fuse-element, plug contacts and said display device with said signaling element being arranged held in one half of the housing.
