Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1: as shown in Figure 2, the electrothermal tube of this band overtemperature protection system, mainly comprise electrothermal tube shell 1 and overtemperature protection system 2, the outer eduction rod 8 of described overtemperature protection system 2 one end is set with plastic bead 7, by the head port position of compacting electrothermal tube shell 1, outer eduction rod 8 and plastic bead 7 are fixed together; The outer circumference surface place that described outer eduction rod 8 is connected with plastic bead 7, is provided with lines 8-1.Make to compress between outer eduction rod 8, plastic bead 7 and electrothermal tube shell 1 three by the crimping at electrothermal tube mouth of pipe position, play fixing outer eduction rod 8 and mouth of pipe position sealing function, because eduction rod 8 is provided with lines 8-1 outside, after the crimping of the electrothermal tube mouth of pipe, make outer eduction rod 8 add frictional force with the Contact of plastic bead 7, better prevent mutual rotation between the two.The other end of described overtemperature protection system 2 is drawn and is provided with overtemperature protection system pin 5; described resistance wire 4 is fixedly connected with overtemperature protection system pin 5 by the mode of reducing wrapping wire; the mode be fixedly connected with has welding and riveted joint; resistance wire 4 wrapping wire adopts the mode of reducing, is convenient to the connection of resistance wire and overtemperature protection system pin 5.
Embodiment 2: as shown in Figure 3, is with the difference of embodiment 1, and described thermel protection device pin 5, after end flaps, is fixedly connected with resistance wire 4; Resistance wire 4 wrapping wire adopts traditional cylindrical shape winding, thermel protection device pin 5 is adopted the method for doubling, then puts into the resistance wire 4 wound.
Embodiment 3: as shown in Figure 4, is with the difference of embodiment 1, is set with adapter sleeve 6 between described thermel protection device pin 5 and resistance wire 4, and resistance wire 4 is fixedly connected with overtemperature protection system pin 5 by the mode of reducing wrapping wire.Resistance wire 4 wrapping wire adopts the mode of reducing, and between resistance wire 4 and overtemperature protection system pin 5, an adapter sleeve 6 on cover, is convenient to the connection of resistance wire 4 and overtemperature protection system pin 5.
