Definitions
- the present invention relates to a method for sol ⁇ dering and simultaneously insulating two outer ends of for instance cables, tubes, pipes and the like which are to be connected. Connecting of two or more outer ends of cables, tubes, pipes and the like occurs regularly in different technical fields. Insulation is of particular importance in the connecting of cables such as electricity cables. In addition to effecting a connection by means of solder- ing, insulating of the connection must also take place. According to the prior art this insulation can be achieved in different ways. The most conventional method makes use of a soldering iron with which connection of the ends is first carried out, whereafter for instance insulating tape is wrapped round the effected join.
- shrinking sleeve which is provided on its inner side with solder and glue rings which may or not be impregnated with flux.
- solder and glue rings which may or not be impregnated with flux.
- the known prior art has a number of drawbacks howev ⁇ er.
- the conventional method of soldering and subsequently arranging insulating tape requires a number of separate operations. The ends must first be held close to each other while they are soldered. It is then necessary to wait until joining has been properly effected, only after which the insulating tape can be wrapped therearound.
- the known shrinking sleeve has the drawback that during heating particularly the flux, which is intended to first clean the ends for connecting and to ensure a good distribution of the solder, flows away from the ends for connecting before the solder has melted. Flux has the tendency to flow to the heat source. Since this is locat ⁇ ed on the outside of the shrinking sleeve the flux will flow away from the connection to be made. It is then no longer possible to obtain a good connection.
- the method according to the invention relates to a number of specific embodiments.
- the insulation can thus be carried out by arranging an insulation element round the end for connecting and heating said element.
- This sequence is of particular interest when a double-walled shrinking sleeve is used as insulation element. It is however also conceivable to arrange a heat-proof tape round the ends for connecting, around or on which a soldering element is arranged and to carry out the soldering after heating.
- a standard poly- olefin tube can likewise be used as insulation element.
- soldering elements to be used.
- a piece of solder impreg ⁇ nated with flux can thus be wound quite simply round the ends for connecting or laid thereon.
- a soldering wire impregnated with flux can also be used.
- figure 1 shows applying of the flux
- figure 2 shows arranging of the solder and the insulation element
- figure 3 shows heating of the insulation element
- figure 4 shows an alternative embodiment wherein a soldering wire is used.
- the method according to the invention is illustrated with reference to the soldering of an earth wire 1 onto a cable 2.
- flux 4 is applied to the ends for connecting.
- a soldering element 5 is subse ⁇ quently laid on the flux 4, whereafter an insulation element 6, in the case shown a shrinking sleeve, is arranged.
- the shrinking sleeve is shrunk round the connection (see figure 3) . Only when the shrinking sleeve has made contact with the connection will the heat also be transmitted to the solder and the soldering take place.
- figure 4 In an alternative embodiment of figure 4 can be seen how the outer end of an earth wire 1 is fixed to a cable 2 by means of a soldering wire 8 wound therearound. The shrinking sleeve 6 is then arranged round the soldering wire 8. Insulation is brought about by shrinking of the sleeve 6, only after which the soldering takes place.
- the present invention provides a method with which connections wherein insulation is required can be carried out in safe and certain manner. Arranging the insulation first has the advantage that run-off of flux and solder is no longer possible.
