Abstract
Abstract Previously, hook-up wires were glued to a mounting board by means of spot gluing. As disclosed herein, the insulated hook-up wire is first continuously coated with a coating of hot-melt adhesive and is then placed on the mounting board and simultaneously bonded by means of a heated laying tip of an application tool, similar to a soldering bit. When passing through the laying tip, the hook-up wire is briefly heated, whereby the coating of hot-melt adhesive is melted. The insulating layer of the hook-up wire has a higher temperature stability and is thereby not altered. In the immediately following application of the hook-up wire to the mounting board, the hot-melt adhesive cools and connects the hook-up wire to the mounting board.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A method for fixing an insulated electric hook-up wire to a circuit board, comprising the steps of: providing the hook-up wire with a hot-melt adhesive on its outer insulation; providing a heated laying tool with a heated tip which has a guidance channel for heating the wire and for pressing the wire onto the board; after applying the hot-melt adhesive on the outer insulation, placing the hook-up wire in the guidance channel; and pressing the wire onto the board and continuously moving the laying tool along the wire as the wire with the hot-melt adhesive heated up at the tip is fed through the guidance channel.
Claim 2
Independent Claim
106 words
A method for fixing an insulated electric hook-up wire to a circuit board, comprising the steps of: providing the hook-up wire with a hot-melt adhesive on its outer insulation; providing a heated laying tool with a heated tip which has a guidance channel for heating the wire and for pressing the wire onto the board; after applying the hot-melt adhesive on the outer insulation, placing the hook-up wire in the guidance channel; and pressing the wire onto the board and continuously moving the laying tool along the wire as the wire with the hot-melt adhesive heated up at the tip is fed through the guidance channel.
Claim 3
Dependent Claim
39 words
A method according to claim 1 including the step of pressing the wire against the mounting board by an abutment surface of the guidance channel at a wire exit and which presses against the top surface of the wire.
Claim 4
Independent Claim
142 words
A method for fixing an electric hook-up wire to a mounting surface, comprising the steps of: providing a length of hook-up wire to be laid with a hot-melt adhesive on its outer insulation; providing a heated laying tool having a heated tip and an abutment surface at a wire exit, a curled portion at a wire entrance, and a laterally open wire guidance channel running from the abutment surface to the curled portion such that the wire passes beneath the abutment surface and above the curled portion; inserting the hook-up wire into the laterally open guidance channel; and pressing the wire with the abutment surface against the mounting board and simultaneously heating the previously applied hot-melt adhesive so as to melt the adhesive at the point of pressing, and thereafter moving the heated tip along the mounting surface to lay the wire.
Claim 5
Independent Claim
142 words
A method for fixing an electric hook-up wire to a mounting surface, comprising the steps of: providing a length of hook-up wire to be laid with a hot-melt adhesive on its outer insulation; providing a heated laying tool having a heated tip and an abutment surface at a wire exit, a curled portion at a wire entrance, and a laterally open wire guidance channel running from the abutment surface to the curled portion such that the wire passes beneath the abutment surface and above the curled portion; inserting the hook-up wire into the laterally open guidance channel; and pressing the wire with the abutment surface against the mounting board and simultaneously heating the previously applied hot-melt adhesive so as to melt the adhesive at the point of pressing, and thereafter moving the heated tip along the mounting surface to lay the wire.
Claim 6
Independent Claim
99 words
A method for at least sectional fixing of an electric hook-up wire to a mounting board, comprising the steps of: providing a laying tool and a hot-melt adhesive; applying the hot-melt adhesive to the hook-up wire at least over an entire length to be laid in a separate apparatus apart from the laying tool and prior to laying of the hook-up wire; heating the adhesive on the wire to a gluable temperature at a current point of application of the hook-up wire during laying by heating the laying tool; and thereafter laying the hook-up wire with the laying tool.
Claim 7
Independent Claim
99 words
A method for at least sectional fixing of an electric hook-up wire to a mounting board, comprising the steps of: providing a laying tool and a hot-melt adhesive; applying the hot-melt adhesive to the hook-up wire at least over an entire length to be laid in a separate apparatus apart from the laying tool and prior to laying of the hook-up wire; heating the adhesive on the wire to a gluable temperature at a current point of application of the hook-up wire during laying by heating the laying tool; and thereafter laying the hook-up wire with the laying tool.
Claim 8
Dependent Claim
50 words
A method according to claim 4 including the step of heating the hook-up wire by a heating curled portion of the laying tool at least at an underside of the laying tool facing the mounting board and pressing the wire against the mounting board with the laying tool immediately thereafter.
Claim 9
Dependent Claim
81 words
A method according to claim 5 including the step of providing an abutment portion spaced from the heating curled portion and which presses against a top portion of the wire to press the wire against the mounting board during the step in which the hook-up wire is laid, providing a laterally open wire guidance channel formed between the heating curled portion and the abutment portion, and prior to laying the hook-up wire, inserting the wire laterally into the wire guidance channel.
