Abstract

The cable leathrough, for leading cables through housing walls etc., consists of a hexagonal nut attached to one end of a helix. The helix is terminated at the other end by a ring. The cable passes axially through the helix and the nut and is clamped into the nut. The nut has a slot into the centre of one side. A clamping ridge moves in this slot, as two screws are tighthened, and clamps the cable. The helix prevents kinks in the cable and is manufacture in one piece with the hexagonal nut. The helix is formed from permanently pliable, yet impact resistant material which is proof against corrosion.

Description

Vorrichtung zur Kabelein- und Durchführung mit Zugentlastung und Knickschutz -~~~~~~~~~~~~ Vorrichtung zur Kabel ein und Durchführung mit Zugentlastung und Knickschutz Die Anmeldung bezieht sich auf eine Ein- und Durchführl1ng mit Zugentlastllng und Knickschutz für Kabel Leitungen, Schläuche und Teilen ähnlicher Gestalt in Gehäusen und durch Trennwände.Device for cable entry and exit with strain relief and kink protection - ~~~~~~~~~~~~ Device for cable entry and lead-through with strain relief and kink protection The application relates to an entry and lead-through length with strain relief and kink protection for cables, lines, hoses and parts of a similar shape in housings and through partitions.

Einstückige Kabel ein und Durchführungen haben gegenüber den mehrteiligen beachtliche Vorteile hinsichtlich ihres bestimmungsgemäßen Gebrauchs als auch ihrer Fertigung, wie unverlierbar fixierte Knickschutzspirale einfache Handhabung, Anschluß an alle gängigen Gehäuse ohne Demontaqe der Kabeieinfiihrung, geringe Lagerhaltung; Einsparung von Fertigungstoleranzen. Einstückige Kabelein- und Durchflihrungen können allein oder im Zusammenhang mit einem Verschraubungsunterteil und zusätzlicher Dichtung verwendet werden.One-piece cables and bushings have compared to the multi-part considerable advantages in terms of their intended use as well as their Production, such as captive, fixed kink protection spiral, easy handling, connection to all common housings without dismantling the cable entry, low inventory; Saving of manufacturing tolerances. One-piece cable entries and feedthroughs can alone or in connection with a screw connection base and additional seal be used.

Kennzeichen der Erfindung sind - daß die Kabeleinführung aus einer Wendel mit einem der Kabelaufnahme dienenden, axialen Kerndurchgang und einem hohlzylindrischen Anschlußkörper in einstückiger Verbindung besteht - daß an der Außenmantelfläche des Anschlußkörpers ein Anschlußgewinde, vorzugsweise ein Panzerrohrgewinde angebracht iste - daß zwischen Wendel und Anschlußgewinde ein verbind dender Montagebund1 vorzugsweise ein Außensechskant, die formschlüssige Montage ermöglicht, - daß eine schlitzartige Ausspartlna im Außensechskant des Anschlußkörners, senkrecht zur Durchfiihruns<-richtung der Hohlzylinder bis auf zwei Stege, welche die annähernd halbsechskantförmiae Schale begrenzen, zur Aufnahme des Zugentlastungsbügels dient, - daß die auf der Basis des Schlitzes verbleibenden Stege je eine zentrische Bohrung zur Aufnahme z*B.Characteristics of the invention are - that the cable entry from one Helix with an axial core passage serving to accommodate the cable and a hollow cylindrical one Connection body is in one-piece connection - that on the outer circumferential surface the connection body has a connection thread, preferably an armored pipe thread iste - that between the helix and the connecting thread a connecting assembly collar 1 is preferred an external hexagon, which enables form-fitting assembly, - that a slot-like recess in the external hexagon of the connecting body, vertical for the implementation direction of the hollow cylinder except for two webs, which approximate the limit the half-hexagonal shell, serves to accommodate the strain relief bracket, - That the webs remaining on the base of the slot each have a central bore for recording z * B.

selbstschneidender Schrauben bei der Bügelbefestigung enthalten, - daß das Wendeiende an der Kabeleinführungsstelle durch einen konzentrischen Ring begrenzt ist, - daß der Querschnitt des Wendels durch seine geometrische Form annähernd als Hochkantrechteck, bei Betrachtung in Durchgangsrichtung, eine große Biegesteifigkeit und damit Stützwirkuna qegen Beanspruchungen senkrecht zur Kerndurchgangsrichtunq besitzt, - daß die begrenzt elastische Stützwirkuna der Spirale durch Ausführung in dauerelastischem, schlagfesten, korrosionsbeständigem Natur- oder Kunststoff unterstützt wird. self-tapping screws included in the bracket mounting, - that the turning end at the cable entry point through a concentric ring is limited, - that the cross section of the helix is approximately due to its geometric shape as an upright rectangle, when viewed in the direction of passage, a great flexural strength and thus supportive action against stresses perpendicular to the direction of passage through the core - that the limited elastic support effect of the spiral by execution in permanently elastic, impact-resistant, corrosion-resistant natural or plastic is supported.

Ein Ausführunasbeispiel der Erfindtlng ist in den Figuren 1 und 2 dargestellt: Figur 1 zeigt eine Ansicht der erfindungsgemäßen Kabelein- und Durchführung mit Zugentlastung und Knickschutzwendel 1 Figur 2 die erfindunasgemäße Kabel einführung im Schnitt.An exemplary embodiment of the invention is shown in FIGS. 1 and 2 shown: Figure 1 shows a view of the cable entry and implementation according to the invention with strain relief and anti-kink helix 1 Figure 2, the cable according to the invention on average.

Die in dem Ausführungsbeispiel dargestellte Kabelein-und Durchführung ist als dallerelastischem, schlagfesten, korrosionsbest.indigen Material auf natürlicher oder künstlicher Basis gefertigt.The cable entry and lead-through shown in the exemplary embodiment is more natural as a daller-elastic, impact-resistant, corrosion-resistant material or artificial base.

Die Kabelverschraubuna besteht aus der Knickschutzwendel (1), welche einstSickig mit dem Anschlußkörper (2) verbiunden ist, Der nach innen durch den Hohlzylinder (3) bearenzte Anschlußkörper ist an seiner Außenkontur als Gewindezapfen (4) und Sechskantmontagebund (5) ansgefiihrtO Die Schlitzöffnung (6) dient der Aufnahme des 7ugentlastunqsbügels (7), der durch die Schrauben (8), mittels der Aufnahmebohringen (9), befestigt wird.The cable gland consists of the kink protection coil (1), which Once connected to the connecting body (2), which goes inwards through the Hollow cylinder (3) machined connection body is on its outer contour as a threaded pin (4) and hexagonal assembly collar (5). The slot opening (6) is used to accommodate of the 7ugentlastunqsbügel (7), which through the screws (8), by means of the mounting holes (9), is attached.

Der bei Betrachtung in Durchgangsrichtuna dazu parallele Querschnitt des Wendels entspricht annähernd einem Hochkantrechteck (10) und versteift dadurch die Wendel. An der Kabeleinführung begrenzt ein konzentrischer Ring (11) die Wendel.The cross-section parallel to it when viewed in the direction of passage of the helix corresponds approximately to an upright rectangle (10) and thereby stiffens the helix. A concentric ring (11) delimits the helix at the cable entry point.
