The invention relates to a method for fabricating an optical plug connector, according to which the optical waveguide is immersed with the exposed optical fiber into a powdery adhesive and is withdrawn from the same, whereby particles of the powdery adhesive remain adhered to the surface of the fiber. The fiber with the adhered particles is then inserted into the boring of the ferrule of the plug connector and is fixed therein. The ferrule is heated to a temperature greater than or equal to the melting temperature of the adhesive and is maintained at this temperature. A particular suitability for use in the field is achieved by virtue of the fact that: the bonding of the fiber to the ferrule is carried out in a battery-operated hand-held device (130); the plug with the ferrule is inserted into and held on a receptacle (160) that is placed on the hand-held device (130); inside the receptacle (160), the ferrule is surrounded by a battery-operated electric heating element; the optical waveguide with the fiber is then inserted into the plug and is fixed inside the same by actuating means (129, 136, 137, 141, 143, 151) arranged inside the hand-held device (130), and; finally, the adherence is effected by heating the ferrule using the heating element.
A method for making up an optical plug-in connector, which comprises a connector (100) with a connector pin (101), in which method the light-guiding fiber (205) of an optical waveguide (200) is exposed, inserted into a bore (114) in the connector pin (101) and fixed in the bore (114) by adhesive bonding with a powdered reaction adhesive, which is transformed into the liquid state by melting and, in the liquid state, is made to react and crosslinks to form a temperature-resistant bond, and in which method the optical waveguide (200) with the exposed light-guiding fiber (205) is dipped in the powdered adhesive and pulled out again, particles of the powdered adhesive remaining adhering to the surface of the fiber (205), the fiber (205) with the adhering particles is inserted into the bore (114) of the connector pin (101) and fixed there, and the connector pin (101) is brought to and held at a temperature which is greater than or equal to the melting temperature of the adhesive, characterized in that the adhesive bonding of the fiber (205) to the connector pin (101) is performed in a battery-operated hand-held device (130), in that firstly the connector (100) is inserted with the connector pin (101) into a receptacle (160) attached to the hand-held device (130) and is held there, in which receptacle (160) the connector pin (101) is surrounded by a battery-operated electrical heating element (167), in that the optical waveguide (200) is then inserted with the fiber (205) into the connector (100) and fixed in the connector (100) by means of actuating means (129, 136, 137, 141, 143, 151) arranged in the hand-held device (130), and in that finally the adhesive bonding is carried out by heating up the connector pin (101) with the heating element (167).
