Description

Die abgefederten Druckstücke der bekannten Mantelklemmen sind derart ausgebildet, daß die Druckfeder um ein im Durchmesser entsprechend verjüngtes Teil des Druckstückes liegt, wodurch der Querschnitt und die Festigkeit des Druckstückes verringert wird. Die Befestigung des Druckstückes erfolgt durch einen am Druckstück angedrehten Zapfen, der durch den Kopf des Mantels ragt und von außen so vernietet wird, daß sich das Druckstück drehen und in Druckrichtung noch bewegen läßt. An Stelle des angedrehten Zapfens wird das Druckstück auch vielfach mittels eines nagelähnlichen Stiftes von außen festgehalten. Bei diesen Ausführungen geht der Schlitz zur Aufnahme des den Mantel drehenden Schraubenziehers über das für die Nietung bzw. den Nagelkopf notwendige Senkloch. Beim Festziehen des Mantels auf den Anschlußdraht schiebt sich nun das Druckstück in den Mantel hinein, wobei die Nietung bzw. der Nagelkopf sich dem Schraubenzieher nähern und ihn im ungünstigsten Falle herausdrücken können. Außerdem wird der Kontaktdruck über eine relativ kleine Fläche vom Mantel auf das Druckstück übertragen.The spring-loaded pressure pieces of the known jacket clamps are of this type designed that the compression spring around a part whose diameter is correspondingly tapered of the pressure piece, whereby the cross-section and the strength of the pressure piece is decreased. The pressure piece is attached to the pressure piece by means of a turned pin that protrudes through the head of the jacket and riveted from the outside becomes that the pressure piece can rotate and still move in the direction of pressure. At In place of the turned pin, the pressure piece is also often by means of a nail-like one Pen held from the outside. In these versions, the slot is used for receiving of the screwdriver turning the jacket over the one for the rivet or the nail head necessary countersunk hole. When tightening the jacket on the connecting wire pushes itself now the pressure piece into the jacket, whereby the rivet or the nail head is approach the screwdriver and, in the worst case, push it out. In addition, the contact pressure is transferred over a relatively small area from the jacket to the Transfer pressure piece.

Die Erfindung ist durch eine Manteldruckstückkombination gekennzeichnet, welche die vorgenannten Nachteile beseitigt.The invention is characterized by a jacket pressure piece combination, which eliminates the aforementioned disadvantages.

Fig. i zeigt die Mantelklemme im Schnitt C-D der Fig. 2 in gelöstem Zustand; Fig. 2 zeigt sie im Schnitt A-B der Fig. i in angezogenem Zustand.Fig. I shows the jacket clamp in section C-D of FIG. 2 in a released state State; Fig. 2 shows it in section A-B of Fig. I in the tightened state.

Ein einteiliges Druckstück i hat an einem Ende eine runde Platte 2, die im Mantelkopf in einer Kammer 3 durch einen nach innen umgebördelten Rand 4 der Kammer festgehalten wird. Die Druckfeder 5 liegt unter Druckspannung in der Kammer zwischen der Platte und dem Mantelboden. Letzterer wird von dem Schraubenzieherschlitz 6 nicht durchbrochen. Das Druckstück i hat unter der Platte 2 zwei Schultern 7, die sich heim Aufschrauben des Mantels auf einen Anschlußdraht 8 fest auf die durch den nach innen gebördelten Ränd 4 der Kammer entstandene Kreisfläche auflegen und eine relativ große Druckfläche bilden.A one-piece pressure piece i has a round plate 2 at one end, that in the jacket head in a chamber 3 by an inwardly beaded edge 4 the Chamber is detained. The compression spring 5 is under compressive stress in the Chamber between the plate and the bottom of the jacket. The latter is held by the screwdriver slot 6 not broken. The pressure piece i has two shoulders 7 under the plate 2, the Heim screwing the jacket onto a connecting wire 8 firmly on the through Place the circular area that has been created on the inwardly beaded edge 4 of the chamber and form a relatively large printing area.

Der Querschnitt des genannten, durch Kontaktdruck beanspruchten Teiles des Druckstückes, also zwischen Kontaktflächen 9 und Schultern 7, ist konstant.The cross-section of the part mentioned, which is stressed by contact pressure of the pressure piece, that is between contact surfaces 9 and shoulders 7, is constant.
