Problems solved by technology

Known techniques related to rolling solder lead to insufficient adhesion during the pre-processing process or to undesired bubble formation during soldering
The following disadvantages usually occur when tinning in a liquid tin bath: Insufficient or irregular distribution of the amount of tin
In the case of stranded ribbon conductors, however, the known technique causes the following problems: additional solder reservoirs must be placed or retinned
A further problem arises in that the pre-tinned stranded strip material cannot be passed through and soldered to a contact, in particular a vehicle plug contact or the like

Embodiment Construction

[0044] Figure 1a A conventional twisted ribbon 1 is shown with a rectangular cross-section. By the action of pressure in the direction of the center of gravity of the cross section, the twisted strip 1 can be brought into a pressed state, as in Figure 1b as shown in. according to Figure 1c The stranded hose 2 has a substantially circular cross-section with a circular cavity 3 .

[0045] Such cavities, however in the form of approximate stranded wires, are also based on Figure 1b Obtained after pressing of the twisted strip 1.

[0046] as in figure 2 As can be seen in the schematic diagram, a rigid contact 4 can be applied to the stranded wire hose 2 by surface-side welding.

[0047] according to image 3 The illustration in FIG. 2 shows how rod or tube solder 5 , in particular so-called tube solder, can be introduced into cavity 3 of litz wire hose 2 by means of solder supply mandrel 6 .

[0048] Specifically, the solder 5 is pushed into the cavity 3 of the litz w...

Abstract

The invention relates to a method for uniform coating of a metallic or metallized textile hose (2), in particular a twisted ribbon hose (2), with solder (5). According to the invention, a rod or tube of solder (5) is provided, the outer diameter or cross-sectional area of ​​said rod or said tube being chosen to be smaller than the inner diameter or inner cross-sectional area of ​​said textile hose. Furthermore, the solder ( 5 ) is inserted into at least one longitudinal section of the fabric hose ( 2 ) and fixes it in the cavity of the fabric hose. The textile hose can be further processed in a manner known per se, in particular by heating it up to the melting point of the solder introduced.

Description

technical field [0001] The invention relates to a method and a device for the homogeneous coating of metallic or metallized textile hoses, in particular twisted ribbon hoses, with solder or flux. Furthermore, the device relates to a fabric hose, in particular a twisted ribbon hose, with a solder or flux-flux amount of metal in the interior of the hose. Background technique [0002] Known twisted straps consist of metallic fabric hoses, in particular copper fabrics, which are rolled according to the width and height desired by the customer. The twisted straps can be produced using conventional weaving techniques, ie are based on weaving, and have high flexibility and, depending on the dimensions, sufficient current-carrying capacity or low ohmic resistance. [0003] Stranded ribbon conductors are also used in electrical systems and domestic appliances, especially when moving parts have to be contacted and / or when high mechanical vibration loads are present. [0004] In orde...
