Definitions

  • the invention relates to an enclosure for accommodating one or more conductor connection terminals, which are designed as through-connectors.
  • the invention also relates to a set made up of such a housing and one or more conductor connection terminals, which are designed as through-connectors.
  • Conductor connection terminals are available in a variety of designs in the electrical sector, e.g. as screw terminals, e.g. in the form of luster terminals, or as spring-loaded terminals, which have spring-loaded terminals for connecting electrical conductors.
  • Conductor connection terminals which are designed as feed-through connectors, are characterized in that they have at least two conductor clamping connections for connecting and electrically connecting at least two electrical conductors. The conductor insertion openings for these conductor connections are arranged on diametrically opposite sides of the housing of the conductor connection terminal.
  • the conductor connection terminals are available with differently designed housings, in particular with different external cross-sectional shapes.
  • the conductor connection terminals are not or only slightly protected against the ingress of dirt and moisture. In some applications, increased protection is required, especially against moisture. For example, there is a need for protection against moisture according to protection class IP68.
  • An enclosure for an electrical connector is, for example, from U.S. 3,680,036 known.
  • the object of the present invention is to specify a housing for accommodating one or more conductor connection terminals, which are designed as through-connectors. Furthermore, a set formed with this is to be specified.
  • the invention has the advantage that a housing that is easy to use and assemble by the user is specified for accommodating one or more conductor connection terminals in the form of through-connectors.
  • the housing can be constructed with relatively few individual parts, which promotes simple construction and assembly.
  • the housing is suitable for the implementation of a simple and reliable sealing concept that does not result in incorrect use by the user.
  • the housing advantageously has a tubular central receiving body which is closed on the peripheral side. This ensures a good shielding effect of the conductor connection terminals arranged in the housing or in the opening of the central receiving body against environmental influences.
  • the continuous opening ensures that the conductor connection terminals can be easily received and/or attached in the receiving body.
  • the receiving body can be completely or partially cylindrical on the outside, but it can also have other cross-sectional shapes on the outside.
  • the receiving body advantageously has an inner cross-sectional contour which is adapted to the outer contour of conductor connection terminals to be received therein. This also promotes easy assembly by the user.
  • the conductor connection terminals arranged in the continuous opening can be held reliably and are also protected from vibration loads.
  • first and the second screw cap can be connected to the central receiving body via a threaded connection. This allows the housing to be assembled easily and intuitively.
  • the first screw cap and/or the second screw cap each has a through-opening for the passage of an electrical cable whose electrical conductors (wires) are connected to the conductor connection terminals arranged in the housing.
  • the first thread and/or the second thread is designed as an external thread. This also promotes a simple and intuitive assembly of the parts of the housing.
  • the threaded connections can be dimensioned relatively large and accordingly have a high strength.
  • the first screw cap and / or the second screw cap in the manner of a Union nut be formed.
  • a strain relief for the electrical cable routed through the through-opening of the screw cap can also be formed or arranged in a screw cap, for example by means of a clamping element having clamping lugs.
  • the receiving body can be designed in one piece or in multiple pieces, e.g. in the form of a single injection-molded component or in the form of several injection-molded components.
  • the receiving body is designed in one piece with the inner cross-sectional contour.
  • the continuous opening has an inner cross-sectional contour that is constant in the axial direction.
  • the conductor terminals to be inserted into the opening can be specifically guided through the inner cross-sectional contour right at the beginning of the insertion process.
  • the inner cross-sectional contour of the continuous opening has a star shape. This optimizes the use of space in the interior of the receiving body. Due to the star shape, longitudinal webs are also formed on the inside of the opening, which further increase the strength or rigidity of the receiving body.
  • the housing has a first seal which can be pressed against the receiving body by means of the first screw cap by tightening the threaded connection of the first screw cap on the first end face, and/or the housing has a second seal which can be pressed against the receiving body by means of the second screw cap by tightening the threaded connection of the second screw cap on the second end face.
  • first seal and/or the second seal can be designed as an annular seal.
  • the first seal and/or the second seal can be rotationally symmetrical with an inner opening aligned with the through-opening of the receiving body.
  • the first seal and/or the second seal has a profile in an axial sectional plane which has a radially extending branch and an axially extending branch projecting therefrom, the radially extending branch being predominantly radial Extends direction of the receiving body and the axially extending branch extends predominantly in the axial direction of the receiving body.
  • the first seal or the second seal can provide a good seal both for the separating plane between the respective protective cap and the receiving body and for the cable that is passed through.
  • the radially extending branch of the respective seal can be pressed onto the receiving body by means of the respective screw cap.
  • the axially extending branch can bear sealingly against the outer surface of a cable routed through the seal.
  • the seal thus has an L-shaped cross-section.
  • the first seal and/or the second seal can advantageously be made of an elastic material, for example an elastomer such as rubber or silicone.
  • the housing consists of the central receiving body, the first screw cap, the second screw cap, the first seal and the second seal.
  • the receiving body has only one continuous opening. This allows a particularly simple and ergonomic insertion of the conductor connection terminals in the continuous opening.
  • the first screw cap and/or the second screw cap has a corrugation, a square contour and/or a hexagonal contour in at least one area of its outer surface.
  • the receiving body can also advantageously have a contour on its outer peripheral surface for applying a tool, for example in the form of at least two flattened areas opposite one another, so that a counterhold can be ensured when tightening the screw caps.
  • the object mentioned at the outset is also achieved by a set consisting of a housing of the type explained above and one or more conductor connection terminals, which are designed as through-connectors, the one conductor connection terminal or the several conductor connection terminals being receivable in a form-fitting manner in the through-opening of the receiving body.
  • the advantages explained above can also be realized in this way.
  • the form-fitting accommodation of the conductor connection terminal or the several conductor connection terminals means that they are held at a defined point, and in particular they can be held with little play in the radial direction, so that they cannot excessively collide against the inner walls of the receiving body even under vibration loads.
  • one or more conductor connection terminals each have spring clamp connections for connecting electrical conductors.
  • the user can connect the electrical conductors to the conductor connection terminals particularly easily and in many cases without tools.
  • Make the spring clamp connections also ensures a long-lasting reliable contact.
  • Such a spring-loaded terminal connection can have a clamping spring, for example, with a busbar also being able to be present depending on the design.
  • the conductor connection terminal can have an actuating element for actuating the clamping spring, for example a pivotable actuating lever.
  • the indefinite term “a” is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component”. If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°).
  • the Figures 1 and 2 illustrate that the housing 1 has a tubular central receiving body 2, on the first end face of which a first screw cap 3 is arranged and on the second end face of which a second screw cap 4 is arranged.
  • the first screw cap 3 has an external hexagon contour 31 in a region facing away from the receiving body 2.
  • the first screw cap 3 has an axially continuous opening through which a first cable 5, for example an NYM cable, is passed.
  • the second screw cap 4 has an external hexagon contour 41 in a region facing away from the receiving body 2.
  • the second screw cap 4 has an axially continuous opening through which a second cable 6, for example an NYM cable, is passed.
  • the receiving body 2 has a first thread 21 in the form of an external thread on the first end face.
  • the first screw cap 3 has an internal thread 30 which is associated with the first thread 21 and which is screwed onto the first thread 21 .
  • the receiving body 2 has a second thread 22 in the form of an external thread on the second end face.
  • the second screw cap 4 has an internal thread 40 which is associated with the second thread 22 and which is screwed onto the second thread 22 .
  • a continuous opening 20 is located in the interior of the receiving body 2.
  • a plurality of conductor connection terminals 9 are arranged in this opening 20, to which the respective individual conductors of the cables 5, 6 are connected.
  • a first seal 7 is located between the receiving body 2 and the first screw cap 3 .
  • the first seal 7 has a radially extending branch 71 which is pressed against the end face of the receiving body 2 by the tightened threaded connection of the first screw cap 3 .
  • the first seal 7 also has an axially extending branch 70 which over a certain longitudinal section bears sealingly against the first cable 5 arranged therein. The same applies to the second seal 8.
  • a second seal 8 is located between the receiving body 2 and the second screw cap 4 .
  • the second seal 8 has a radially extending branch 81 which is pressed against the end face of the receiving body 2 by the tightened threaded connection of the second screw cap 4 .
  • the second seal 8 also has an axially extending branch 80 which over a certain longitudinal section bears sealingly against the second cable 6 arranged therein.
  • the figure 4 shows the explained elements in cross section.
  • Steps 3 and 4 can also be reversed in this process.
