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 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 bore 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 because the fasteners (Nut or clamping 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 conductor can be inserted.
- connection end has a threaded bore into which one with a Tapered clamping screw can be 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 advantages achieved by the invention are in particular 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 well embedded in an insulating body, which only requires an 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 clamped directly, the volume resistance is also 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 body 1 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 his.
- the conductor connection end is with a transverse bore 4 passing through it Mistake.
- the stranded conductor 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, threadless 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 in such a way that at least two “adjacent” conductor cross sections can be clamped on (for example 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 therefore 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 Extend cross hole 4.
- the stripped stranded wire 5 is to the opposite Inserted end into the cross hole.
- the cone tip 11 dips into the Stranded wire 5 and distributes it evenly on both sides of the narrowing Hole 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.

Description
Durch die kegelförmige Spitze der Klemmschraube wird der Leiter allseitig gegen die Innenwand der Querbohrung gepreßt, ohne den Leiter zu beschädigen, wobei nur der Bereich der Bohrungsöffnung der Klemmschraube ausgespart bleibt. Es entsteht eine innige und gasdichte Verbindung. Die erreichbaren Leiterauszugskräfte sind sehr hoch und können mit denen von Crimpverbindungen verglichen werden. Die Verbindung ist wieder lösbar. Da der Leiter direkt angeklemmt wird, ist auch der Durchgangswiderstand gering und die Eigenerwärmung der Klemme ist dadurch ebenfalls sehr gering. Die Gefahr einer Fehlfunktion wird dadurch so gut wie ausgeschlossen.
- Fig. 1
- ein Kontaktelement im Schnitt,
- Fig. 2
- das Kontaktelement mit einem angeschlossenen Leiter, und
- Fig. 3
- eine perspektivische Darstellung des Kontaktelementes gem. Fig. 2 mit einem Betätigungswerkzeug.
In diese Gewindebohrung ist eine Klemmschraube 10 eingeschraubt. Die Klemmschraube ist mit einer Kegelspitze 11 versehen, die in den in die Querbohrung eingeführten Litzenleiter gepreßt wird. Dabei ist das vordere Ende der Klemmschraube vorzugsweise mit einem abgesetzten, gewindelosen Schaft 12 versehen um eine Beschädigung der Litzen des Leiters beim Einschrauben der Klemmschraube durch scharfkantige Gewindegänge zu vermeiden.
Zur Betätigung der Klemmschraube ist diese vorzugsweise mit einem Innensechskant 13 versehen und somit mittels eines Betätigungswerkzeuges 14 einschraubbar.
