Abstract
A sleeve, terminal body, plug body, or the like receives tubular or ring-shaped, normally solid but thermoplastic filler elements, being traversed by a cable or conductor, particularly a portion from which insulation has been stripped. A plunger-like element receives also the cable or conductor and is inserted in one end of the sleeve, or body, the other end being closed by another plunger or body structure. Upon heating, the filler element melts and the plunger or plungers are forced further in to cause melted filler material to fill all voids; the deformed material resolidifies and seals and bonds all parts together.
Claims17
The method of making a moisture-, pressure-, and tension-proof connection which includes at least one element, comprising the steps of:
- providing an annular element to which the connection is to be made and being made of a relatively high-melting material;
- providing one or more of a generally annular thermoplastic filler being a separate component and having a melting point below the melting point of said element, but being normally solid;
- inserting the element in the filler and in a position to be sealed, and inserting the filler in said annular element so that the element has a particular concentric position in relation to the annular element, the annular element at least in parts surrounding the element and being radially spaced therefrom;
- heating the annular element and applying axial pressure to the filler, axial with respect to the annular element, pressure being applicable to the filler on account of the radial spacing between the element and the annular element, so that the filler will melt but not the annular element, and the filler is deformed to fill all voids in the interior of the annular element so as to seal the element and the undeformed annular element so that the element is firmly connected to and sealed against the annular element.
A connection which includes at least one component or element, comprising:
- an annular, high-melting element, one of the components or elements being inserted in the annular element in a particular position;
- a deformed annular filler embedding a portion of the one component or element in the annular element on account of the deformation, the annular element being radially spaced from the component or element;
- and
- a plug element traversed by the one element or component and having a plunger portion and a flange inserted in the annular element, the plunger portion having axially compressed the filler when melted to obtain a sealed, moisture-proof, gas-tight, and tension-proof bond and connection between the plug element, the annular element, and the one element or component portion therein.
