[0002] As far as the applicant knows, the existing electric heater lead-out devices can only be used at room temperature. The commonly used high-temperature-resistant cables are generally made of high-temperature plastic insulating material composite sheaths, which can withstand a temperature of about 200°C, and have short service life and poor electrical conductivity. Low efficiency, poor oxidation resistance, electrical point contact is easy to corrode, easy to aging and other shortcomings, can not meet the use requirements
The effective connection of the electric heater load to the cable cannot be realized at high temperature

Embodiment
[0016] The high-temperature and high-current lead-out line device of this embodiment, such as figure 1 and figure 2 As shown, it includes a load connection copper bar 1, a conductive copper rod 2, a wiring compartment steel pipe 3, an insulating ceramic body 4, and a cable connection copper bar 5.
[0017] The load connecting copper bar 1 and the cable connecting copper bar 5 are respectively fixed at both ends of the conductive copper rod 2 , and the steel tube 3 of the junction box and the two insulating ceramic bodies 4 are sleeved in the middle of the conductive copper rod 2 respectively. The two insulating ceramic bodies 4 are both arranged between the steel pipe 3 and the conductive copper rod 2 in the wiring compartment. One end of each insulating ceramic body 4 all stretches out of the adjacent nozzle of the junction box steel pipe 3 and is shaped on a ring shoulder on this end,
[0018] Insulating gaskets are provided between the two insulating ceramic bodies 4, be...

The invention relates to a high-temperature heavy-current leading-out wire device, and belongs to the technical field of electric heating in electrics. The leading-out wire device comprises a conductive copper rod. The two ends of the conductive copper rod are fixedly provided with a load connection copper bar and a cable connection copper bar respectively; the middle portion of the conductive copper rod is sleeved by a wiring cabin steel pipe and two insulation ceramic bodies; the two insulation ceramic bodies are arranged between the wiring cabin steel pipe and the conductive copper rod; one end of each insulation ceramic body extends out of an adjacent port of the wiring cabin steel pipe and forms a circular ring shoulder at the end; and an insulation sealing gasket is arranged between the two insulation ceramic bodies, between the circular ring shoulders of the insulation ceramic bodies and the wiring cabin steel pipe as well as between the insulation ceramic bodies and the load connection copper bar and the cable connection copper bar. The leading-out wire device has the advantages of being simple in overall structure, large in current-carrying capacity and good in insulating property, can enable an electric heater load to be connected with the cable effectively under high temperature, and can be applied to the occasions of large load capacity and high temperature.
Description
technical field [0001] The invention relates to a high-temperature and high-current lead-out device, in particular to a lead-out device with simple structure, large carrying capacity and good insulation performance. Background technique [0002] As far as the applicant knows, the existing electric heater lead-out devices can only be used at room temperature. The commonly used high-temperature-resistant cables are generally made of high-temperature plastic insulating material composite sheaths, which can withstand a temperature of about 200°C, and have short service life and poor electrical conductivity. Low efficiency, poor oxidation resistance, electrical point contact is easy to corrode, easy to aging and other shortcomings, which cannot meet the requirements of use. An efficient connection of the electric heater load to the cable cannot be achieved at high temperatures. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
