Abstract
A suction-type desoldering device includes an elongated tubular heater assembly secured to the forward end of a hollow handle by a radial flange on the assembly. A removable solder collecting chamber adapted to have a vacuum created therein is disposed within the handle and has an open end connected in solder flow communication with the heater assembly by means of a compressible sealing member disposed between the flange and the open end of the chamber. The heater assembly includes a tubular sleeve secured to and extending through the flange adjacent the seal. A tubular support having a length of electric resistance heating wire wrapped therearound is mounted coaxially within and spaced from the tubular sleeve and has one end thereof extending freely into the collection chamber and the other end thereof receiving a removable tubular desoldering tip. Wires connecting the heating wire to a source of electrical energy pass through an opening in the sleeve communicating with a radial groove in the surface of the sealing member engaging the flange. The seal is compressed by biasing means in the handle to such an extent that the groove closes tightly about the connecting wires to block t…
