Definitions

  • the invention relates to a contact element with a connection for stranded conductors, in particular contact element for high currents, that with a connection end is provided, wherein the connection end has a transverse bore into which the Stranded wire can be inserted, and one arranged perpendicular to the transverse bore Threaded hole is provided, which extends into the cross hole, and a clamping screw with a tapered tip into the threaded hole can be screwed in.
  • the conductors are to be mechanically fastened to such contact elements and be electrically connected to the contact element.
  • the contact force must be maintained permanently.
  • the leader should be clamped between metal surfaces without undue damage become and be solvable again.
  • terminals known for a 90 ° angled feed / discharge of the respective conductor are designed as a bolt clamp or their connection via a screw in a threaded hole on the contact element he follows.
  • the conductor must be provided with a cable lug for connection become. This is squeezed or pressed onto the conductor.
  • The is only possible with special tools (pliers). They need one On-site assembly because of their large lever arms takes up a lot of space and is expensive. Also Hydraulically operated tools are still relatively large, heavy and have a high purchase price.
  • the large cable lug dimensions require a large amount of space Connection.
  • the clamping point must be accessible from the outside as the fasteners (Nut or gill screw) and with the provided Tools with the specified tightening torque have to. Subsequent protection of the terminal point as intended Condition (under electrical voltage) against touching requires an additional one Expenditure.
  • connection end with a Cross bore is provided, into which the stripped conductors can be inserted.
  • connection end has a threaded bore into which one with a Tapered clamping screw is screwed on the stripped Head acts.
  • CH 448 204 is also a connector body made of insulating material known, which has a plug end designed as a contact socket.
  • a transverse bore is provided into which a stranded conductor can be inserted which is clamped and contacted by means of clamping screws can.
  • a cable connector is also known, the one Has base body with a transverse bore for receiving a conductor.
  • a transverse bore for receiving a conductor.
  • a pin-shaped contact part which can be pressed in Contacting caused by pressure on the conductor.
  • the invention has for its object a contact element of the beginning mentioned type in that this is easy to manufacture and the connection of the conductors is possible without special tools, the Space requirement of the contact elements should be as small as possible.
  • the contact element from one one-piece, cylindrical body made of electrically conductive material consists of one end as a plug end and the other end as Conductor connection end is formed such that the transverse bore in the conductor connection end is provided, and is designed as a stepped bore, the Conductor insertion side of the hole has the smaller diameter that the threaded hole, running axially in the base body, starts from the plug end, and that the clamping screw can be actuated through the plug end is.
  • the advantages achieved with the invention consist in particular in that the stranded conductors can be clamped to a certain length without additional and expensive tools only with a hexagon key of the appropriate size without additional aids such as cable lugs or wire end sleeves.
  • the dimensions of the terminal area never exceed the external dimensions of the high-current contact.
  • the space requirement is minimal.
  • the contact can be easily embedded in an insulating body, which only needs one opening for the conductor connection and the plug-in area.
  • the clamp can be operated from outside at any time. It is possible to check the clamping force and, if necessary, retighten the clamping screw when installed.
  • the conductor Due to the conical tip of the clamping screw, the conductor is pressed on all sides against the inner wall of the transverse bore without damaging the conductor, only the area of the bore opening of the clamping screw being left out. An intimate and gas-tight connection is created. The conductor pull-out forces that can be achieved are very high and can be compared with those of crimp connections. The connection can be released again. Since the conductor is directly connected, the volume resistance is low and the self-heating of the terminal is also very low. This virtually eliminates the risk of malfunction.
  • a contact element designed as a socket contact shown, which consists essentially of a cylindrical base body 1 there is a plug end 2 and a conductor connection end 3. It can here designed as a contact socket plug end optionally also formed as a contact pin be.
  • the conductor connection end is with a transverse bore 4 passing through it Mistake.
  • the stranded wire 5 to be connected (see. Fig. 2 and 3) inserted.
  • the cross hole is designed as a stepped hole, the bore on the conductor insertion side 6 having a smaller diameter having.
  • the cross hole is on the Conductor insertion side is also provided with a chamfer 8, which allows the insertion of a Leader relieved.
  • the base body 1 is provided with an axial, central threaded bore 9 which extends into the transverse bore and ends here.
  • a clamping screw 10 is screwed into this threaded bore.
  • the clamping screw is provided with a conical tip 11 which is pressed into the stranded conductor inserted into the transverse bore.
  • the front end of the clamping screw is preferably provided with a stepped, unthreaded shaft 12 in order to avoid damage to the strands of the conductor when the clamping screw is screwed in due to sharp-edged threads.
  • the cone tip and the transverse bore are matched to one another so that at least two adjacent "conductor cross sections can be clamped (e.g. 50 mm 2 and 70 mm 2 or 95 mm 2 and 120 mm 2 ).
  • the clamping screw it is preferably provided with a hexagon socket 13 and can thus be screwed in by means of an actuating tool 14.
  • the total cross section only has to be in the intended clamping area.
  • the tip of the clamping screw 10 may not yet in the initial state Project cross hole 4.
  • the stripped wire conductor 5 is to the opposite Inserted end into the cross hole.
  • a commercially available Hex screwdriver the end of which through the longitudinal hole in the Contact element pushed into the hexagon socket of the clamping screw can be tightened.
  • the cone tip 11 dips into the Stranded wire 5 and distributes it evenly on both sides of the narrowing Bore cross section. In the area of the bore heel Braid pressed against the wall. Since the strand behind the paragraph 7 a little finds larger hole, it is expanded a little more there.
