Technical solution adopted by the utility model to solve its technical problems is:
A kind of electric heater improving safeguard construction, including body, body is interior to be equipped with installation cavity, is provided in installation cavity a plurality of
Locating slot is installed with heat-generating pipe on each locating slot, and the both ends of the heat-generating pipe tightly enter formula and are socketed with insulating positioning sleeve, absolutely
Fever end surfaces in edge positioning sleeve are extended with connector, and connector makes heat-generating pipe realize heating power by being welded with conducting wire,
The other end of insulating positioning sleeve is opposite with the side wall of installation cavity, and offers the threading groove passed through suitable for conducting wire, connector with lead
It is arranged with insulating positioning sleeve outside the junction of line, effectively prevent junction under long term high temperature effect, the gum cover on conducting wire melts
And solder joint melts and connector is caused to detach and peel off with conducting wire, while heat-generating pipe being avoided to be caused due to being heated to extend to both ends
Heat-generating pipe, which breaks conducting wire or excessively extends, pulls apart connector and conducting wire, to effectively prevent short circuit electric leakage, Ignition Phenomena, improves
Safety in utilization, while also extending the service life of complete machine.
Specifically, when heat-generating pipe fever expansion extends to both ends, heat-generating pipe pushes insulating positioning sleeve to be promoted to two side,
When insulating positioning sleeve is advanced to certain safe distance pot, the other end of insulating positioning sleeve and the side wall of installation cavity are mutually supported, are mutually supported
Control heat-generating pipe continues to extend afterwards, makes connector avoid excessively extension from causing to disconnect with conducting wire, and threading groove extraction wire, energy
The other end of insulating positioning sleeve is avoided to break conducting wire.
Interface channel is axially offered in insulating positioning sleeve, the both ends of interface channel pass through the both ends of insulating positioning sleeve, should
Structure is convenient for extraction wire, simple in structure, convenient for production.
The insulating positioning sleeve is hollow ceramic jacket, larger, the ceramic material of the connection position heating of connector and conducting wire
Good heat-insulation effect.
The insulating positioning sleeve is hollow rectangular protective case, and rectangular protective case is avoided that insulating positioning sleeve rolls, causes
Threading groove is turned over to bottom.
Threading groove is opened in the top surface of insulating positioning sleeve, avoids conducting wire from being pressurized to greatest extent, and heat-generating pipe is heated clever when extending
Movement living.
Threading groove both sides have upwardly extended guiding side plate, simple in structure, mobile accurate.
The utility model has the beneficial effects that:
A kind of electric heater of the improvement safeguard construction of the utility model, it is simple in structure, outside the junction of connector and conducting wire
It is arranged with insulating positioning sleeve, effectively prevent junction under long term high temperature effect, the gum cover on conducting wire melts and solder joint melts
And connector is caused to detach and peel off with conducting wire, while heat-generating pipe being avoided to cause heat-generating pipe to break to lead due to being heated to extend to both ends
Connector and conducting wire are pulled apart in line or excessively extension, to effectively prevent short circuit electric leakage, Ignition Phenomena, improve safety in utilization,
Also extend the service life of complete machine simultaneously.
