Definitions

  • the invention relates to an encapsulated, non-detachable electrical conductor connection in the field of electrical installation, telecommunications technology and electrical device and electrical system construction using a connecting sleeve made of insulating material and a method for its production.
  • twisting of the conductors has been known as a method for connecting conductors.
  • This simple process at that time limited to copper conductors, does not meet today's requirements for an electrical connection in its original form, especially since aluminum has been added as the conductor material, which is more difficult to master than copper in terms of connection technology.
  • the electrical wire connector (OS -23 20 854) is based on the twisting of two conductors especially for the connection and for the series connection of electrical detonators.
  • the CH-PS 55 04 91 proposes a wire connector that is screwed onto a number of electrical conductor ends and thereby connects them.
  • a pointed helical spring serves as the fastening element, which is made corrosion-resistant with a zinc coating and provided with a wax coating which acts as a lubricant.
  • An insulating socket is also provided.
  • Konex clamp which uses a metal part with a conical internal thread, which is also screwed onto the conductor.
  • the aim of the invention is to create a corrosion-proof connection of two-conductor and multi-conductor combinations with a connecting sleeve made of insulating material without the use of additional elements regardless of the conductor material, so that no corrosive influences have to be feared even when connecting conductors made of different materials.
  • the object of the invention is to achieve a completely insulated encapsulation of the conductor connection.
  • the contact resistance of the connection should be small, the manufacture simple and possible in a short time.
  • a good material economy is to be achieved compared to the previously known connection methods.
  • a connection sleeve which has three differently designed cross-sectional areas .., is used to implement the encapsulated permanent connection.
  • the holding area arranged at the end of the sleeve has a receptacle on the inside which is adapted to the number of conductors and the conductor cross section connecting conductor and outside at least two key surfaces.
  • the holding area consists of two different cross-sectional shapes arranged one behind the other, the upper part for holding four conductors and the lower part for two conductors being designed such that two opposing holding engravings of the upper part are tapered into the lower part.
  • the middle contact area has pressure ribs adapted to the number of conductors, the spacing diameter of which is smaller than the diameter of the twisted connection, so that the pressure ribs, in cooperation with thinner wall parts in between, i.e. elastic zones, exert a contact pressure on the twisted conductors.
  • the pressure ribs can be rectangular in cross-section or tapered radially towards the inside of the sleeve.
  • the encapsulation area forming the sleeve entrance corresponds in its inner diameter to the circumference of the insulated conductors.
  • the connecting sleeve according to the invention is completely or partially filled with a carrier substance in which contact-improving means are embedded.
  • the carrier substance can be an adhesive or a fat, e.g. B. technical petroleum jelly.
  • the contact-improving agent can consist of non-metallic particles, e.g. B. Si0 2 exist.
  • the method for producing the encapsulated, non-detachable electrical conductor connection is characterized in that the stripped ends of the solid and / or flexible conductors to be connected are inserted into the holding area of the connecting sleeve described above and by twisting the connecting sleeve by at least one turn relative to the conductors fixed at the sleeve entrance the stripped conductor parts are twisted.
  • the contact-improving agents in the form of small particles, embedded in a carrier substance, fill in the remaining cavities and penetrate into the conductor material at the points where metallic conductors come into contact and cause current-conducting bridges with low resistance. At the points of contact of the conductors with pressure ribs of the connecting sleeve, the contact-improving means clamp.
  • the carrier substance closes the conductor connection airtight at the sleeve entrance.
  • the adhesive After binding with the connecting sleeve and the twisted conductors, the adhesive forms a compact body and, including the conductor insulation, results in a completely insulated encapsulation of the metallic conductors.
  • the conductors 1 prepared for connection are stripped at the conductor ends 2.
  • the conductors 1 can consist of copper, aluminum or other conductor materials.
  • the conductor ends 2 are inserted into a connecting sleeve 3.
  • the connecting sleeve 3 is partially filled with a contact-improving agent 4 embedded in a carrier substance and is protected against atmospheric influences by a separator layer 5 protected.
  • the separator layer 5 is destroyed and the carrier substance with the contact-improving agent 4 is displaced so that it fills the remaining cavities in the interior 6 of the connecting sleeve 3.
  • the contact-improving agent 4 can consist of non-conductive particles, for. B. Si0 2 , exist and the carrier substance, in which the contact-improving agent 4 is embedded, can be an adhesive.
  • the connecting sleeve 3 consists of three different cross-sectional areas, the holding area 7, the contact area 8 and the encapsulation area 9.
  • the conductor ends 2 are fixed in the holding area 7 and the electrical conductors 1 are held at the sleeve entrance 10. After attaching a tool to the wrench flats 11 on the outside of the holding area 7 and rotating the same, a twisting 12 of the conductor ends 2 occurs in the contact area 8.
  • the insulated conductors 1 are twisted slightly in the encapsulation area 9.
  • the holding area 7 according to FIG. 2 is advantageously in accordance with FIGS. 3 to 5 in two different cross-sectional areas 7.1. and.7.2. designed.
  • FIG. 4 shows the cross section through the upper part 7.1 of the holding area 7.
  • Four engravings 13 are arranged in a cloverleaf shape.
  • Two opposite engravings 13 are tapered in the lower part 7.2. of the holding area 7 continued, so that there an oval holding engraving 13.1. 5 is present.
  • Two of the conductors 2 to be connected are always first up to the holding engraving 13.1. of the lower part 7.2. of the holding area 7 introduced. Additional conductors 2 are held in the upper part 7.1 of the holding area 7. Are, for example, the engravings 13 and 13.1. Designed for 2.5 mm 2 conductors, their different design also ensures secure holding of 1.5 mm 2 conductors and any combination of these cross-sections. Connections and combinations of even smaller conductor cross sections are possible with such a connecting sleeve. Thus, for conductor connections up to 6 mm 2 , only two connecting sleeves of different sizes can be used. The force transmission for producing the twist 12 in the contact area 8 takes place via the key surfaces 11.
  • the conductor ends 2 are inserted through the insertion recesses 15 into the holding area 7.
  • the respective insertion recesses 15 are delimited by pressure ribs 16 which are connected by thinner wall parts 17.
  • the thinner wall parts 17 act as elastic zones.
  • the spacing diameter 18 of the pressure ribs 16 is smaller than the later twisting diameter 19.
  • the spacing diameter 18 of the pressure ribs 16 is expanded to the twist diameter 19 and the pressure ribs 16 are pressed outwards.
  • the originally round wall parts 17 flatten out and overall, contact pressure is exerted on the twist 12 via the pressure ribs 16.
  • the particles of the contact-improving agent 4 penetrate into the surface of the conductor ends 2 and there cause a reduction in the electrical contact resistance.
  • the contact surfaces 21 between the pressure ribs 16 and the conductor ends 2 there is a clamping with a considerable increase in the frictional resistance between the pressure ribs 16 and the twist 12. This prevents the connecting sleeve 3 from being easily pulled off from the twist 12.
  • the airtight closure of the twist 12 from the outside air takes place.
  • the carrier substance 22 containing the contact-improving agent 4 fills the remaining cavities between the electrical conductors 1 and the inner wall 23 of the connecting sleeve 3 in the encapsulation region 9.
  • the carrier substance 22 is displaced into the encapsulation region 9 when the conductors 2 are inserted, and during the twisting the conductor insulation is drawn into the encapsulation region 9 up to the beginning of the contact region 8.
  • an adhesive as carrier 22 and non-conductive particles, for. B. Si0 2 , as a contact-improving agent 4, a completely insulating encapsulation of the entire connection.
  • the pressure ribs 16 according to FIG. 6 can be tapered radially towards the inside of the sleeve, as shown in FIGS. 9 to 11.
  • the spacing diameter 18 of the pressure ribs 16.1. is smaller than the twist diameter 19 of a two-wire connection with the smaller possible conductor cross-section (ie 2 X 1.5 mm 2 for a connection sleeve 2.5 mm 2 ).
  • the pressure ribs 16.1. depending on the number and Cross-section of the conductor 2 more or less bent and exert a pressure on the twist in cooperation with the elastic wall parts 17. This creates an additional contact pressure that counteracts relaxation.
  • the completely closed design of the conductor connection does not allow control of the degree of twist, so that subjective influences can be effective.
  • the use of a transparent or translucent sleeve material reveals the twist from the outside and allows a qualitative assessment by visual inspection.
