Definitions

  • the invention relates to a cable gland.
  • Cable glands are used to insert electrical cables or the like into switch or distribution boxes or to connect electrical cables to system parts, for example junction boxes or plug connectors. It is essential that the screw connection ensures a high level of tightness of the cable connection. Cable glands are therefore preferably used in areas where high tightness is important, for example in chemical factories, in the offshore area or on boats.
  • a disadvantage of known cable glands is that the cable outlet is always mounted on the housing at a certain angle. Especially in tight spaces, it can happen that the electrical cable is kinked when connecting the cable gland and is therefore damaged and must be replaced with another cable.
  • the object of the present invention is to provide a screwed cable gland which enables an electrical cable to be connected easily and securely even in a small or cramped installation space. This object is achieved by a cable gland with the features of claim 1.
  • the basic idea of the invention is based on connecting the connecting piece carrying the actual screw connection to a mounting body and designing this connection in such a way that the connecting piece can be moved into different positions with respect to the mounting body.
  • the connecting piece is not directly attached to the switch or distribution box or to the system part. Rather, the assembly body is arranged on the housing so that the connecting piece taking up variable positions can be positioned largely independently of the geometry of the housing.
  • the connecting piece can thus both perpendicular to Housing surface, ie at an angle of up to 90 °, as well as horizontally to the housing surface, that is to say quasi adjacent to the housing with an angle of up to 0 °.
  • the connecting piece can be attached to the mounting body in such a way that any angular positions are possible.
  • connection piece and the mounting body are arranged in such a way that they share a common connecting surface which runs obliquely to the longitudinal connection piece axis (claim 2).
  • the connection piece is positioned by rotating the connection piece about its longitudinal axis. In other words, the different positions of the connecting piece are achieved by rotating it by an angle of rotation in the range between 0 ° and 180 °.
  • An embodiment according to claim 3 is particularly advantageous, according to which the connecting surface extends obliquely to a base surface of the mounting body.
  • a base surface of the mounting body is understood to mean the surface with which the mounting body is attached to the housing, that is to say to the switch or distribution box or to the system part.
  • a suitable inclination of the connecting surface makes it particularly easy to achieve a horizontal and a vertical position of the connecting piece.
  • all angular positions can be set between 0 ° and 90 °.
  • the mounting body has at least two connecting surfaces (claim 4).
  • the cables can, for example, run parallel to one another or, coming from different sides, run towards one another. It is also possible to connect cables that run from completely different directions or at different angles to the cable gland without having to bend or kink the cables for the connection. This is particularly possible if the connecting surfaces are inclined to one another (claim 5), since this results in particularly favorable positions of the connecting pieces. In other words, it is possible to adjust the position of the connecting piece on the mounting body independently of one another.
  • the mounting body has a curved surface on which the connecting piece is movably arranged.
  • the connection piece has at its foot end a tab which is designed in accordance with the curvature of the mounting body surface and which extends in a cap-shaped manner over the curvature of the mounting body.
  • This embodiment can be designed in such a way that the mounting body surface and the connecting piece tab form a kind of ball joint or ball guide.
  • the connection piece can be positioned anywhere on the surface of the mounting body in the X or Y direction.
  • the surface of the mounting body preferably has a guide slot for forming a web guide for the connecting piece (claim 7).
  • the connection piece is positioned by moving it along the guide slot.
  • the guide socket preferably has at its foot end provided with the rag
  • Guide element on, for example in the form of an L or T-piece, which is designed such that it ensures a securing of the connecting piece in engagement with the guide slot.
  • the tab is designed in particular in such a way that it overlaps the guide slot in any position of the connecting piece, in order to ensure sufficient tightness.
  • FIG. 1 is a perspective view of a first embodiment with two inclined connecting pieces
  • Fig. 2 is a side view of the first embodiment with two vertically placed connecting pieces
  • Fig. 3 is a perspective view of the first embodiment with one
  • Fig. 4 is a side view of a second embodiment of the invention.
  • the cable gland 1 shows a cable gland 1 according to the invention, as can be used, for example, as a power supply or a power outlet for high or three-phase current.
  • the cable gland 1 has a mounting body 2 and two connecting pieces 3, 4 connected to the mounting body 2. Each connection piece 3, 4, the in
  • Essentially consists of a hollow cylindrical base body 5, has both a threaded end 6 with a union nut 7 for producing the cable gland and a foot end 8 for connection to the mounting body 2.
  • the cable gland is of the compression type, with two parts which are in engagement with one another via a thread ensuring that the seal is fixed to the cable, or whether a cable gland of the membrane type is used in which the seal adapts to the cable diameter.
  • the connecting pieces 3, 4 are detachably attached to the connecting faces 12 of the mounting body 2 by means of screws 11 with their connecting faces 10 running obliquely to the longitudinal axis 9 of the connecting neck. To ensure a particularly high level of tightness, this connection is sealed by additional sealing elements, for example sealing rings.
  • the two connecting surfaces 12 of the mounting body 2 run obliquely to one another, being arranged at an obtuse angle to one another in the manner of levels of a roof. At the same time they run
  • connection surfaces 12 obliquely to a base surface 13 of the mounting body 2, via which the mounting body 2 is attached to a housing 14.
  • the connecting pieces 3, 4 By rotating the connecting pieces 3, 4 about their longitudinal axis 9, they are positioned relative to the mounting body 2. In the exemplary embodiment, for example, they can assume the position shown in FIG. 1, in which the longitudinal axis 9 forms an angle of approximately with the base surface 13 of the mounting body 2 Occupies 27 °. If you loosen the screw connections between the connecting pieces 3, 4 and the mounting body 2, the connecting pieces 3, 4 can still be positioned in a parallel division, as shown in FIG. 2.
  • the angle between the connecting piece longitudinal axis 9 and the base surface 13 of the mounting body 2 is in each case 90 °.
  • any intermediate positions 0 are also possible.
  • Mounting body 2 and a corresponding bevel of the connecting surface 10 on the connecting piece 4, 5 can also achieve a parallel position of the connecting piece longitudinal axis 9 and base surface 13.
  • connecting pieces 3, 4 can remain in the vertical position, while the other connecting piece 3, 4 is fixed in any other angular position.
  • screw connections instead of the screw connections, snap or snap connections can also be used.
  • additional securing elements for example tension springs or other spring elements, can be used to ensure the required tightness, which ensure that the connecting piece 3, 4 bears securely against the mounting body 2. 5

In this way, a vertical position of the connection piece 18 is achieved precisely when the cap 19 is arranged on the one outer stop 23 of the mounting body surface formed by the base surface 13, as shown in FIG. 4.
