Definitions
- pole terminals or connector pin terminals for connecting phase conductors and neutral of a 230V AC voltage network of a copper alloy, preferably a copper-zinc material with spring property.
- a copper-zinc material preferably a copper-zinc material with spring property.
- a good electrical function ie. H. a satisfactory power line
- a good mechanical function i. H. Normally required contact forces for the clamping of the connected conductor and the clamping inserted plug pins to ensure.
- a contact shown which is composed of two parts.
- the one, cage-like part includes a screwless terminal for the stripped end of a conductor to be connected.
- the second clamping part which is enclosed in the cage-like part, forms two contact spring legs, between each of which a lamp contact pin is inserted.
- EP 1 020 954 A2 is an electrical terminal with a housing provided with at least one insertion path with a bus bar for the free end of an electrical conductor and with a clamping spring arranged in the housing, which presses against the insertion path and with a second connection point on the busbar for another conductor.
- the invention has for its object to provide an optimized Steckdosenpolitch for a socket insert.
- the advantages achieved by the invention are, in particular, that the proposed pole terminal assembly requires a reduced use of material, ie there is a reduction of the copper alloy material, for. As the copper-zinc material. Despite the additional required stainless steel material results in a considerable overall cost savings. Above all, however, there are advantageously very small relative movements of the "pin retention contour" and consequently on the pin and during the insertion of the pin. Outer spring (over-spring contact spring assembly) and inner spring (Polklemmenkomponente) are advantageously constructed in one piece, ie, both the retaining spring for the Desisteckenden conductor and the outer spring for applying the required male contact force. Furthermore, in generally known pole terminals, it is made of a copper alloy occurring problem of clamping force reduction at elevated temperature and simultaneous mechanical stress eliminated by the connector pins.
- the Polklemmenkomponente the Steckdosenpolnapsins is integrally formed and bent from a corresponding punched copper alloy sheet.
- the over-spring contact spring assembly of the socket contact is also formed in one piece and from a suitably punched metal with spring properties, in particular stainless steel sheet, bent. Alternatively, it is also possible to carry out the over-spring contact spring assembly in two parts or in three parts.
- the over-spring arms 20 and 21 of the over-spring contact spring assembly 19 form outer springs and exert a spring force on the two contact legs 4 and 5, so as to exert a defined high holding force on an inserted pin.
- both the contact spring arms 23 and 24 and the locking arms 25 and 26 engage in the hollow-channel conductor entries 14 and 15 so as to form retaining springs for the at least one conductor and to accomplish both the clamping and the locking of at least one inserted conductor.
- the guide plate 13 serves as additional central support for the over-spring contact spring assembly 19th
- the line clamp can be made single-ended, d. H. the structural components 23 and 25 or 24 and 26 are combined so that only one leg in each case fulfills the holding function.
- FIG. 12 is a top perspective view of a copper alloy bus terminal component (see FIG Fig. 2 ) and from below (see Fig. 3 ).
- the pole terminal component 3 has a first contact leg 4 and a second opposing contact leg 5, wherein each of these contact legs 4 and 5 is provided at the end with a contact tulip 6 or 7 is.
- a stop 8 or 9 is formed on the contact legs 4 and 5, wherein these two stops 8, 9 in the rest position, ie when not plugged pin, press against each other.
- Each of the two contact legs 4 and 5 merges into an integrally formed leg web 10 or 11, wherein these two leg webs 10, 11 are connected to each other in a U-shaped manner via a bridge 12.
- This bridge 12 ends in a tongue-like protruding guide plate 13.
- the bridge 12 are opposite to the leg webs 10 and 11 respectively hollow channel-shaped respectively U-shaped conductor entries 14 and 15 provided in profile, each having a boundary web 16 and 17.
- a first conductor in the introduction profile with hollow channel-shaped conductor insertion 14 / boundary web 16 and a second conductor in the introduction profile with hollow channel-shaped conductor insertion 15 / limiting web 17 can be inserted.
- leg webs 10, 11 of the contact legs 4, 5 are arranged at a slight angle directly to the bridge 12, so that the resilient leg webs 10, 11 on the insides of the conductor entries 14, 15th are connected. Due to this geometric configuration, the relative movements of the "plug pin holding contour" and consequently of the plug pin caused by the insertion of a plug pin are advantageously very small.
- the locking arms 25 and 26 press end against an inserted conductor and cause such a locking of the conductor. As soon as a force is exerted on one of the unlocking arms 27 and 28, which is effected by a "spring release”, not shown, respectively, a "spring release plate”, the relevant locking arm 25 or 26 releases from the inserted conductor at the end, whereby it can be pulled out.
- Fig. 5 is a view of a Polklemmenbaunosti shown.
- the pole terminal assembly 1 is in its rest position. It is easy to see that the over-spring arms 20 and 21 of the over-spring contact spring assembly 19 press as outer springs against the contact legs 4 and 5 of the Polklemmenkomponente 3. The pressing against each other of the contact legs 4 and 5 is limited by the stops 8, 9 touch.
- Fig. 5 shows also serving for conductor clamping and conductor locking spring with the over the leg webs 10, 11 with the contact legs 4, 5 connected conductor entries 14, 15 of the Polklemmenkomponente 3 and the over-spring bridge 22 including the Entriegelungsarmen 27, 28 of the over-spring contact spring assembly 19th
- Fig. 9 a sketch for explaining "critical relative movements” shown.
- critical relative movements in which the plug pin moves from A to B during insertion into the pole terminal assembly and moves in reverse from B to A during withdrawal from the pole terminal assembly are disadvantageous and to be avoided.
- such "critical relative movements” occur in the proposed socket contact only to a very small extent.
- over-spring contact spring assembly 19 is based on a one-piece executed over-spring contact spring assembly 19.

When choosing the copper-zinc material, a compromise must be made to ensure a good electrical function, ie. H. a satisfactory power line, and on the other hand a good mechanical function, i. H. Normally required contact forces for the clamping of the connected conductor and the clamping inserted plug pins to ensure.

Der Erfindung liegt die Aufgabe zugrunde, einen optimierten Steckdosenpolkontakt für einen Steckdoseneinsatz anzugeben.The invention has for its object to provide an optimized Steckdosenpolkontakt for a socket insert.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Steckdosenpolkontakt für einen Steckdoseneinsatz, welcher eine Polklemmenbaugruppe aufweist, die zusammengesetzt ist
- aus einer Polklemmenkomponente aus einer Kupferlegierung mit zwei Leitereinführungen sowie zwei sich gegenüberliegenden Kontaktschenkeln mit jeweils endseitigen Kontakttulpen zur Einführung und Klemmung eines Steckerstiftes und
- aus einer Überfeder-Kontaktfeder-Baugruppe aus einem Metall mit Federeigenschaften,
- wobei die Polklemmenkomponente die elektrische Funktion der Stromleitung vom Leiter zum Steckerstift abdeckt,
- wobei die Überfeder-Kontaktfeder-Baugruppe die mechanische Funktion abdeckt und hierzu über zwei gegen die Kontaktschenkel pressende Überfederarme die Klemmkraft für die Steckerstiftklemmung sicherstellt und über eine Kontaktfeder mit mindestens einem Kontaktfederarm sowie mindestens einem Verriegelungsarm die Klemmkraft für die Leiterklemmung und die Leiterverriegelung sicherstellt,
- wobei die Leitereinführungen über eine Brücke miteinander verbunden sind und Schenkelstege der Kontaktschenkel unmittelbar an der Brücke angreifen, so dass die federnden Schenkelstege an den Innenseiten der Leitereinführungen angebunden sind.
- from a Polklemmenkomponente of a copper alloy with two conductor entries and two opposite contact legs each with end-side contact tulips for insertion and clamping of a connector pin and
- from an over spring contact spring assembly made of a metal with spring properties,
- wherein the pole terminal component covers the electrical function of the power line from the conductor to the pin,
- wherein the over-spring contact spring assembly covers the mechanical function and this ensures the clamping force for the Steckerstiftklemmung via two pressing against the contact legs over-spring arms and ensures the clamping force for the Leiterklemmung and the conductor lock via a contact spring with at least one contact spring arm and at least one locking arm
- wherein the conductor entries are connected to each other via a bridge and leg webs of the contact legs act directly on the bridge, so that the resilient leg webs are connected to the insides of the conductor entries.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die vorgeschlagene Polklemmenbaugruppe einen reduzierten Materialeinsatz erfordert, d. h. es ergibt sich eine Reduzierung des Kupferlegierung-Materials, z. B. des Kupfer-Zink-Materials. Trotz des zusätzlich erforderlichen Edelstahl-Materials ergibt sich eine beträchtliche Gesamteinsparung bezüglich der Kosten. Vor allem jedoch treten vorteilhaft sehr geringe Relativbewegungen der "Steckerstift-Haltekontur" und folglich am Steckerstift und während des Einsteckens des Steckerstiftes auf. Außenfeder (Überfeder-Kontaktfeder-Baugruppe) und Innenfeder (Polklemmenkomponente) sind vorteilhaft einteilig aufgebaut, d. h. sowohl die Haltefeder für den einzusteckenden Leiter als auch die Außenfeder zum Aufbringen der erforderlichen Stecker-Kontaktkraft. Ferner wird das bei allgemein bekannten Polklemmen aus einer Kupferlegierung auftretende Problem einer Klemmkraftverringerung bei erhöhter Temperatur und gleichzeitiger mechanischer Belastung durch die Steckerstifte beseitigt.The advantages achieved by the invention are, in particular, that the proposed pole terminal assembly requires a reduced use of material, ie there is a reduction of the copper alloy material, for.

Von Wichtigkeit bei der Polklemmenbaugruppe 1 ist, dass die Überfederarme 20 bzw. 21 der Überfeder-Kontaktfeder-Baugruppe 19 Außenfedern bilden und eine Federkraft auf die beiden Kontaktschenkel 4 bzw. 5 ausüben, um derart eine definiert hohe Haltekraft auf einen eingesteckten Steckerstift auszuüben.Of importance in the
