Definitions

  • connection elements Because in the case of mechanical stress on the connection elements, if this is due to bending, for example the stress is also transferred the fuse element. However, this is primary or exclusive to achieve certain electrical properties designed, which generally has the consequence that the fuse element is accordingly narrow and thin-walled and is therefore not mechanically resilient. If the fuse element mechanically stressed, there is a risk that - possibly unnoticed - form cracks that characterize the Change fuse element or to a complete Destruction of the fuse element. That is why it is safe Support and fixation of the connection elements immediately on the housing to keep mechanical stress away from the fuse element is necessary.
  • a Fuse holder for holding a fuse link in pairs spaced profile supports for Includes the fuse link to engage in corresponding profile openings on the long sides of the fuse link are provided.
  • the profile supports of the fuse holder are dovetail-shaped educated.
  • the housing of the fuse link which is in the fuse holder is used, is made from a first housing half, in which the connection elements with the fuse element or fuse element be included, and a second half of the housing formed with the open side of the first housing half is closed.
  • the first housing half is designed that the connection elements with the inserted melting element due to special positioning means in a predetermined Positioned and held in the first half of the housing will. It does not matter whether the connection elements as in the prior art in one piece from a metal strip formed or manufactured individually and by welding of the fusible element are connected together.
  • the positioning means are compared to the known fuse links designed so that each connection element individually be recorded and held in the first half of the housing can. As a rule, however, both connection elements are common inserted in the first half of the case after going through the fuse elements have been connected.
  • the second housing half essentially has the function of the lid, which also has the task to press the connection elements firmly into the first half of the housing.
  • the essential feature of the fuse holder according to the invention are the profile supports. It is preferred that at the in the fuse holder to be used at Manufacture the corresponding halves of the profile the long sides are molded so that the fuse link insert easily and correctly in a fuse holder can, the one matched to the profile openings Profile supports is provided.
  • the fuse link shown in Figs. 1-4 has one Housing 1 from a first housing half 1a and a second Half of the housing 1b, each made of transparent insulating material are manufactured in plastic injection molding. Furthermore the fuse link 1 comprises two spaced apart arranged connection elements 2a, 2b made of electrically conductive Material, in particular metal, which is in contact with each other Distance opposite inner areas by a Fusible conductor or a fusible element 10 are bridged.
  • the first housing half 1a for receiving the connection elements 2a, 2b, the are bridged by the fuse element 10 used.
  • the plate-shaped connection elements 2a, 2b on opposite set back according to the opening level of the housing half 1a
  • the second housing half 1b covers the opening of the first housing half 1a and the parts inserted there.
  • Punched holes 8 in the outer areas of the connection elements 2a, 2b serve in the usual way for the electrical Connection in the fuse holder.
  • Fig. 5 shows a fuse holder 25 on a base plate 26 threaded pin 27 carries when inserting the fuse link reach through the punch holes 8, as in the Representation can be seen.
  • Threaded pin 27 carries when inserting the fuse link reach through the punch holes 8, as in the Representation can be seen.
  • spaced profile supports 28 provided in the dovetail-shaped Profile openings 9 on the long sides of the housing 1 of the fuse link grab as the illustration shows.
  • FIG. 5 25 At the front end of the fuse holder shown in Fig. 5 25 are to illustrate an anti-rotation protection for the Cable lug 26c of the cable 26d to be connected, latch 26a so arranged on the base plate 26 of the fuse holder 25 that the eyelet 26b when tightening the nut, not shown cannot turn on the threaded pin 27. Because the Cable lug 26c is always held between two bars 26a, no matter whether the cable lug 26c in the longitudinal or transverse direction the base plate 26 has. The bars 26a are purely schematic shown.
  • Fig. 6 illustrates that the fuse holder shown in Fig. 5 25 can also be modified so that several Fuse links arranged side by side and picked up can be. This arrangement also has the advantage of being lighter Handling when inserting the fuse components, because then only a single fuse holder 25 is used must be, which includes several fuse links.
  • Fig. 7-8 show possibilities for coding fuse links and fuse holders to avoid incorrect assignments, in which in the holder of fuses erroneously Inserts are used that only with higher nominal currents switch off than the rated current rating of this fuse corresponds.
  • FIG. 9 Another type of coding is shown in Fig. 9, where instead of pegs a rhombus 31 of a certain size and arrangement is provided for engagement with an engaging recess on the underside of the housing of the fuse link, not shown.
  • Fig. 7 a z. B. to be realized with pin holes Coding scheme for nine nominal current stages shown, one Incorrect assignment at most due to fuse links with a smaller one Permits nominal current.
  • the digits used in the coding scheme show that the coding in each nominal current level is mirror symmetrical is created so that the assigned security operation can be used in two different positions.
  • a Fuse holder for example, with the rated current level 125 A. would be provided with a fuse link, for example the fuse link for 300 A in the holder is not be usable because the holes in the fuse link missing with 3, 4 and 6 as pins in the fuse holder rated current stage 125 A are provided.
  • a fuse link for the nominal current 100 A would be in this Have the fuse holder inserted, i.e. a fuse link with smaller nominal current.
  • Fig. 8 also shows that the fuse holder 25, and preferably on the profile supports 28 with means for Bringing into place after inserting the fuse link can be provided.
  • the embodiment shows 8 on the profile supports 28 facing inwards Pastes 28a, which when inserting the housing 1 of the First spring the fuse insert outwards to reach it the final position of the fuse link above the Spring back housing 1 to lock the housing 1, as in Fig. 8 showing part of the housing 1 is illustrated.
  • This latching is of particular importance when using the aforementioned coding because the pastes 28a only get into their locking position above the housing 1 if the fuse link - with the correct pin-hole pairing the Coding - all the way down in the fuse holder 25 is performed.
