Definitions

  • the subject matter relates to a seal housing for a cable lug, a cable lug for such a seal housing and a system with a seal housing and a cable lug.
  • connections between two electrical lines are usually made using a cable lug and appropriate screw connections. It is important that the connection point is protected against moisture penetration.
  • this is usually achieved using a shrink tube that is placed over the connection point and then shrunk.
  • a shrink tube especially in conjunction with silicone-coated cables, is problematic with regard to longitudinal water that creeps between the shrink tube and the cable insulation. A complete seal is hardly achievable here.
  • Various types of cable lugs are known from the prior art, with which a cable can be connected to a connecting part of an electrical system.
  • the cable lug is typically connected to one end of a cable, in particular by welding, soldering or crimping in the connection area of the cable lug.
  • the cable lug can then be attached to its fastening area can be connected to a connecting part, for example by passing a threaded bolt of the connecting part through a contact opening and securing it with a nut or by passing a screw through the contact opening and screwing it into a threaded hole in the connecting part.
  • a reliable and low-resistance electrical connection can be established between a cable and a connecting part of an electrical system.
  • the cable lugs are usually provided with a housing to protect the connection of the cable lug with the cable and with the connecting part of the electrical system from corrosion to protect. Furthermore, such housings are used for safety reasons to prevent accidental contact with live parts.
  • Such a contact element with a cable lug, a conductor connected to it and a housing is, for example, from DE 10 2013 021 409 A1 known.
  • the housing is often made of a plastic and can be manufactured, for example, by injection molding. Since high mechanical loads can act on the cable lug when connecting the cable lug to a contact element of an electrical system, especially when tightening a nut or screw, it is desirable to embed the cable lug securely in the housing so that the cable lug does not move even when force is applied the housing and long-term protection against moisture penetration is guaranteed.
  • the publication US 7,530,843 B1 relates generally to an electrical clamp for use in high voltage installations and more particularly to a clamp having a feature for optimal positioning and secure retention of a seal.
  • the publication US 5,346,408 A discloses a seal housing according to the preamble of claim 1 and relates to a battery cable assembly and in particular to a battery cable assembly in which an eye terminal crimped to a battery cable is snap-fitted in a plastic cover and in which the cover seals and seals around a battery terminal in a battery wall engages a battery bolt that is screwed to the battery terminal in the battery wall.
  • the publication EP 3 288 115 A1 refers to a connector.
  • the object of the object was to enable a stable, easy-to-produce connection between a cable lug and a housing, which is protected against moisture.
  • a sealing housing for a cable lug according to claim 1 is proposed.
  • the material of the seal housing is, for example, such a hard material that it enables the cable lug to be anchored particularly firmly in the housing.
  • This can be, for example, a thermoplastic.
  • This can be, for example, a glass fiber reinforced plastic, e.g. PA 6 GF15.
  • the housing is preferably injection molded.
  • the housing has a cable entry running in a longitudinal direction.
  • a cable entry can be an opening in the housing that allows a cable to be inserted into the housing in a sealed manner.
  • the cable entry can be formed as a channel that extends in the longitudinal direction.
  • a cable lug which is installed in the seal housing in the connected state, also extends in the longitudinal direction.
  • the seal housing includes a dome.
  • the cathedral also has a longitudinal extension.
  • the direction of the longitudinal extent of the dome is referred to here as the transverse direction.
  • the transverse direction is transverse to the longitudinal direction, in particular perpendicular to the longitudinal direction.
  • the transverse direction can be a surface normal to an insertion level in which a cable lug can be inserted into the cable entry. This plane lies in particular in the axis of the longitudinal direction.
  • direction can also mean the term “axis”.
  • An axis extends in one direction.
  • An axis defines a straight line along a direction.
  • the longitudinal direction can in particular run through the center of the cable entry and extend in the longitudinal direction of the cable entry.
  • the transverse direction can in particular run through a center point of the through-channel.
  • the transverse direction runs along the longitudinal extent of the through-channel.

  • the locking means can be formed as resilient elements, which can snap resiliently behind a recess in the cable lug.
  • the locking means are essentially pivotable transversely to the longitudinal direction, in particular elastically deformable radially outwards, so that the locking means can bend radially outwards when the cable lug is inserted, the cable lug can slide past the locking means and the locking means then spring back behind the recess in the cable lug can. This means that the locking means are not destroyed when the cable lug is installed.
  • the locking means have a transversely extending receptacle for an expanding tool. With the spreading tool, radially outward spreading force can be exerted on the locking means. This allows the locking means to be removed from the recess on the cable lug and the cable lug can removed from the housing in the opposite direction to the insertion direction.
  • the receptacle can be formed in the form of an arc that extends radially outwards.
  • the locking means runs, for example, omega-shaped in its longitudinal extent.
  • a free space for receiving the locking means is arranged in the receptacle.

  • the guide rails can also be L-shaped in cross section and the cable lug can rest on one of the legs in the insertion direction.
  • One leg can guide the cable lug in the transverse direction and one leg can guide the cable lug in a direction perpendicular to the transverse direction and perpendicular to the longitudinal direction.
  • the guide rails can also be groove-shaped with a groove bottom and groove walls, with the cable lug being guided in the groove.
  • the cable lug is fixed in its degrees of freedom at least in the transverse direction when it is inserted.
  • the latching means be arranged in the area of one leg of the guide rails.
  • the guide rails are characterized in particular by two legs, a groove bottom and a groove wall, possibly two groove walls.
  • the locking means can be on the groove bottom and/or the groove walls on at least one guide rail. It is possible that one or more locking means are provided per guide rail.
  • the locking means are preferably provided on the two guide rails, in particular the groove bottoms of the guide grooves.
  • the locking means are projections or recesses.
  • the locking means on the guide rail extend radially in the direction of the transverse direction of the through-channel. This means that the locking means run radially to the center of the receptacle. An inserted cable lug can snap into these locking devices.
  • the receptacle has an anti-twist protection which is arranged in the longitudinal direction opposite the cable entry.
  • the anti-twist protection is preferably located in the insertion level.

  • the anti-twist protection has a projection extending in the longitudinal direction in the direction of the cable entry or a recess pointing away from the cable entry. This is directed in particular in the radial direction towards the center of the recording. When inserted, such a projection engages in a locking groove in the cable lug. Such a recess accommodates a locking lug on the cable lug when inserted.
  • the cable lug Once the cable lug is inserted into the receptacle, it can no longer be pulled out of the exception due to the locking means in the opposite direction to the insertion direction. At the same time, the cable lug engages with the anti-twist protection. The cable lug can no longer be removed from the anti-twist protection since it can no longer be pulled out of the housing in the opposite direction to the insertion direction. This prevents the cable lug from twisting in the receptacle in the transverse direction.
