Definitions

  • the invention relates to a connection device for coaxial cables according to the preamble of claim 1.
  • DE 44 34 702 C1 is an insulation displacement connection device for coaxial cables known in which both the inner conductor and the outer conductor connection can be implemented using IDC connection technology.
  • a cable connector of the connection housing is with recesses for outer conductor connection means provided, which are inserted from the outside into the recesses and the Cut through the cable jacket until they contact the outer cable conductor. Further connection means are held self-clamping in the cable connection piece, so that there is a permanent connection between the housing and the outer conductor is.
  • the inner conductor connector of the connection device contains a IDC contact element, which has a contact hole into which the inner conductor of the coaxial cable is inserted.
  • the IDC contact element of the inner conductor connector is executed as a stamped and bent part. Especially with small quantities to be manufactured this proves due to the relatively high cost of a stamping and bending tool as a disadvantage.
  • DE 29 50 973 U1 discloses an insulation displacement connection device for electrical connection of an inner conductor of a coaxial cable with a second inner conductor of a second Coaxial cable known.
  • the connection device mentioned has a connection element a slot, which is designed and dimensioned in this way, that its width is at least partially smaller than the diameter of one Inner conductor of a coaxial cable to be connected.
  • the connection element additionally has a recess into which the inner conductor of the coaxial cable is insertable essentially without resistance, with this recess the slot mentioned goes off.
  • This insulation displacement connection device has also been mentioned as a stamped and bent part production disadvantages.
  • connection device according to the preamble of Claim 1 known, in which the inner conductor connector formed as a bent sheet metal part has an axial opening with a constant diameter.
  • the object of the invention is an advantageous design for an inner conductor connector a connection device for coaxial cable, which is an inexpensive Manufacture permitted even for small to medium quantities.
  • the focus here is on features that can be easily identified Realize tool costs that only pay for themselves after large quantities to let.
  • the Slit at the outer end of the bore beveled on the start sides, which the Facilitate the introduction of the coaxial cable inner conductor. Furthermore is the Slot formed in a insulation displacement zone with sharp edges, so that in the Slot inserted coaxial cable does not necessarily end up at its end must be stripped on the inner conductor. This can be used if necessary around the inner cable remaining cable insulation except for the coaxial cable inner conductor are severed and the contact for the inner conductor of the coaxial cable.
  • the inner conductor of the coaxial cable is preferably through a Pressure piece can be pressed into the slot of the insulation displacement element.
  • the coaxial cable inner conductor is opposite the housing of the connection device by the preferably Insulated pressure piece made of plastic.
  • Thrust piece By means of a that acts on the pressure piece Thrust piece can be inserted into the housing.
  • the screw plug through screwing in the screw plug the necessary effort provided on the pressure piece to the inner conductor the coaxial cable into the slot of the insulation displacement element to press.
  • the screw plug is used for fixation of the pressure piece and the inner conductor of the coaxial cable in the slot of the insulation displacement connection element.
  • the coaxial cable outer conductor with the help of a crimping element with the connecting piece connected to the housing.
  • the connector is as Tube piece formed, which between the coaxial cable outer conductor and inner cable insulation can be inserted.
  • the crimp element itself is through a via the coaxial cable outer conductor sliding sleeve realized, for example with a pair of pliers is clamped to the connector on the housing becomes.
  • the coaxial cable outer conductor connect using insulation displacement technology.
  • the connecting piece provided cross holes in the housing, in which Clamping plugs can be used to ensure contact between the housing and manufacture coaxial cable outer conductor.
  • they are Clamping plugs advantageously on the inside with cutting edges equipped so that an existing cable jacket up to the coaxial cable outer conductor can be cut.
  • the inner conductor connector 2 shown in Figure 1 contains an insulation displacement element 21 which axially has a bore 22 has two sections 26 and 27 with different Diameter is divided. This widened the bore 22 jumps from the inside to the outside. Outside Section 27 of the bore 22 has the insulation displacement element 21 has an essentially small wall thickness.
  • the bore 22 arranged slot 23 is on the Coaxial cable inner conductor 31 inserted into slot 23 a spring force is exerted on the inner conductor 31 of the coaxial cable 3 fixed in the slot 23. The one created in this way Spring force increases according to the wall thickness of the insulation displacement element 21 from the outside to the inside.
  • At the diameter jump point between the two sections 26 and 27 of the Bore 23 is an end stop for a tool when inserted of the coaxial cable inner conductor 31 is formed (see also Figure 2).
  • the insulation displacement element 21 has at its free end region beveled startup sides 24 (Figure 1 and Figure 2) on the facilitate the insertion of the coaxial cable inner conductor 31.
  • startup sides 24 Figure 1 and Figure 2
  • the start sides 24 and one Insulation displacement zone 25 it is not necessary to use the coaxial cable 3 (FIG. 3) to be completely stripped down to the inner conductor 31. Any remaining around the inner cable 31 Inner cable insulation 33 becomes when inserting the inner cable 31 severed so that the contact between IDC element 21 of the inner conductor connector 2 and the inner conductor 31 of the coaxial cable 3 is produced.
  • the angular connector shown in Figure 3 for Coaxial cable contains an inner conductor connector in its housing 1 2, which with the inner conductor 31 of a coaxial cable 3 is connected.
  • the coaxial cable 3 is in the present Case completely stripped at its free end.
  • On Pressure piece 4 ensures in connection with a screw plug 41 for a secure hold of the end piece of the coaxial cable inner conductor 31 in slot 23 of inner conductor connecting piece 21.
  • the pressure piece 4 also fulfills the function of a press-in tool, which is the free end of the coaxial cable inner conductor 31 in the insulation displacement element 21 of the inner conductor connector 2 presses in and fixed there.
  • the housing 1 is angled by 90 ° Connection piece 11 with two transverse bores 12 has opposite sides of its wall in the Clamping plugs 5 for contacting the coaxial cable outer conductor 32 are inserted.
  • the clamping plugs 5 have on their the cutting edges 51 facing the coaxial cable 3, which may have an existing cable sheath of the coaxial cable 3 cut through to the coaxial cable outer conductor 32 and contact it with the housing 1.
  • the clamp plugs 5 also have knurls that are fixed in the Cross holes 12 serve.
