Definitions

  • the invention relates to a fuse holder for a fuse link, from the housing two connecting lugs protrude, each of which can be connected to a connecting line on the outside are and are connected to the fuse element within the housing.
  • fuse links which in some applications have a two-part housing not loosely between two ends of a connecting line in the room in question
  • the base plate attached in the vehicle compartment and outgoing from this has profile supports and retaining bars to a fuse link of the type mentioned, including its two connecting lugs, in place of it Fix use.
  • a fuse link of the type mentioned, including its two connecting lugs, in place of it Fix use.
  • the end of each as Jacketed cable designed connecting line must be crimped with a cable lug be provided, the eyelet flush via a punched hole in the respective connecting tab placed and fastened to the connecting lugs via threaded bolts and nuts.
  • the invention is therefore based on the object of a fuse holder at the beginning to improve the type mentioned so that the assembly is simplified and the reliability of the electrical function can be improved.
  • the connecting tab as Crimp connection for direct electrical and mechanical connection to the connecting cable is designed.
  • the assembly effort is considerable reduced, because there is no complicated insertion into the profile supports and transoms as well the appropriate arrangement of the cable lugs on the punched holes in the connection tabs and tightening screws and nuts.
  • the reliability of itself because there are no nuts that can be loosened by vibration, causing the Contact resistance would be very large due to the various connection points.
  • the reliability is instead noticeably increased, wherein Screws, nuts and even two connection points are saved.
  • the crimp connection faces the housing the fuse link towards bending clamps for the electrical conductor; and to Connection line towards clamping parts for mechanical gripping of the jacket of the Connecting cable. Both the bending clamp tabs and the clamping parts serve the Strain relief for the connection line, so that the actual fuse link better is protected, although the fuse holder has the described facilities and advantages has (easier assembly and higher reliability).
  • the fuse element and the Connection tab or the two connection tabs are one unit.
  • the electrical Reliability is and is further increased by this uniform design made possible at all because the fuse element in the new fuse holder against external Tensile loads is protected.
  • the manufacture of such a fuse link is thereby further simplified, so that lower manufacturing costs and lower assembly costs enable an economically more favorable use.
  • the invention is advantageously designed in that the fuse link, the Connection tabs, the bending clamp tabs, the clamping parts and a piece of the connecting line are installed in an outer housing that is sealed against moisture and dirt.
  • the electrical conductor of the connecting cable for the crimp connection with the connecting lug is uncovered and in the vicinity of the uncovered piece the new one grips
  • Outer housing a small piece of the connecting cable, for example a distance of 1 to 5 cm and preferably 2 to 4 cm from the sheath of the connecting line mechanically encompassing clamping parts. You can easily see that through the new outer housing there is a further strain relief, which is in addition to the strain relief by the Fusible conductor housing results.
  • the new outer housing provides an additional one Protection against rotation.
  • the outer housing can preferably be sealed against external influences, so that the dangerous pollutants or moisture does not get into the outer casing penetrate and thus can not affect the fuse link. You get due to the new structure, a point support on a cable ladder and thus a point relief the same if you take this as a connecting line.
  • the new outer housing can, for example, have two half-shells or two half-shells have an O-ring arranged in between.
  • the mechanical and the Moisture protection is thus optimally guaranteed.
  • This advantage is further improved by that the new outer casing is moisture-proof on the connection line, for example the jacket of the cable.
  • manufacturing possibilities result from that in the outer housing on both sides of the housing of the fuse link against the respective bending clamps attached inner supports are attached.
  • they are inner supports attached to the inner walls of the outer housing and allow one Fixing of the connection cable (on both sides) and the fuse link fixed to the housing.
  • the elongated crimp connection preferably extends through this inner one Support through and can be supported against them on at least two sides. By the securing of the crimp connection is also optimally held by the fuse link itself.
  • the two ends of the outer housing are located So in the area of the longitudinal axis of the entire structure, and seen in this longitudinal direction the outer supports are at a distance from the inner supports. Runs in between the connecting line. This is gripped by the outer supports from the outside and thereby held and fixed on the outer housing.
  • the outer housing has a mass is filled with insulating material.
  • This can fix the crimp terminals and the fuse link noticeably increase and drastically improve the anti-rotation protection. You turn namely one connecting line relative to the opposite connecting line, then are no torsional forces on parts in the crimp connection and certainly not on the Transfer the area of the fuse element. But this is an excellent protection against Twisting, against train and also against vibrations guaranteed, especially at Motor vehicles could sometimes lead to loose contacts.
  • the insulating material can also surround the outer housing like a solidified liquid the fuse link, including the crimp connection, excellent against intrusion Protect moisture.
  • fuse link Of the fuse link, generally designated 1, you can see essentially only that two-part housing 2, the two halves of each other via crimped connections 3 are attached. From opposite sides of the housing 2 of the fuse link 1 each extends a connecting tab 4, which in the manner shown as a crimp connection configured and generally designated 5.
  • the connecting line in the form of a cable shown on the right or left in FIG. 4 is 6 designated and by the crimp terminal 5 fixed to the housing 2 of the fuse link 1 connected.
  • the crimp terminal 5 can be here about the soul or not illustrated electrical conductor of a cable (connecting line 6) are placed, after which by bending and crimping the bending clips 8 a mechanical and electrical Attachment of the electrical conductor of the connecting line 6 is carried out.
  • the distance between the two parallel legs of the clamping parts 9 is due to this Transition area 10 larger than between the bending clamp tabs; enough space to hold the to grip the entire connecting line 6, for example its jacket, from the outside. Also the U-shaped bent clamping parts 9 are from above via the connecting line 6 or their Put on the jacket and then crimped so tightly by bending that the clamping parts 9 fully and firmly grasp the connecting line 6. This state is shown in Figure 4.
  • the outer housing 11 can be square, oval or rectangular. It exists preferably made of a hard insulating material and has two parts. In every part there are inner and outer supports 13, 12 arranged so that for mounting the fuse holder 1 to 3 with permanently connected connecting lines 6 to a lower half of the outer housing 11 is placed. The other half of the outer casing 11 is after that put on and screwed tight. Before or after, the inside of the outer housing 11 can also be used be filled with an insulating material or poured out.
