Problems solved by technology

However, this application-specific variety leads to higher logistical and manufacturing complexity and thus higher costs
In addition, in the case of higher and higher rated current requirements, ceramic fuse holders have also encountered their technical limits.

Embodiment Construction

[0032] figure 1 A schematic diagram showing the basic construction of the fuse 1 . The fuse 1 has a first contact element 4 and a second contact element 5 , both of which are made of an electrically conductive material, for example copper. The contact elements 4 and 5 are mechanically fixed and hermetically sealed or tightly connected to a fuseholder 10 , which consists of a solid, non-conductive and as high temperature-resistant material as possible, for example ceramic. The fuse holder 10 generally has a tubular basic shape and is closed pressure-tight to the outside, for example by means of two closure caps 6 . The contact elements 4 and 5 each extend here into the interior of the fuseholder 10 through an opening formed in the closure cover 6 . Arranged in this interior is a so-called fuse 2 which electrically conductively connects the first contact element 4 and the second contact element 5 . To this end, the first end 2 - 1 of the fuse 2 is electrically conductively co...

Abstract

In a processing method according to the invention for producing a fuse holder (10) of a fuse (1) for protecting an electrical circuit, the fuse holder (10) is made of insulating material in one pieceby means of an additive processing method. Here, at least one predetermined first section (11) of the fuse holder (10), which has a first physical mass density, and at least one predetermined second section (12) of the fuse holder (10), which has a second physical mass density unequal to the first physical mass density, are produced by the processing method. In this way, the processing method of the at least one first section (11) and the at least one second section (12) is adapted to respective local force loads of the fuse holder (10) with regard to the mechanical elasticity and the mechanical strength of both sections.

Description

technical field [0001] The invention relates to a processing method for manufacturing a fuse holder, a fuse holder for a fuse and a fuse for protecting a circuit. Background technique [0002] A conductor through which current flows becomes hot. In the case of impermissibly high currents, an impermissibly intense heating of the conductor can occur and lead to melting of the insulating layer surrounding the conductor, which in further variants can lead to burning of the cable. In order to prevent the risk of fire, when the current is too large, that is, overload current or short-circuit current, the current must be cut off in time. This is ensured by means of a so-called overcurrent protection device. [0003] A possible embodiment for such an overcurrent protection device is a fuse, which, through one or more fuses, passes through one or more fuses when the amperage of the circuit insured by the relevant fuse exceeds a defined value for a defined period of time. Melting o...
