Abstract
The utility model relates to a component of an electric heating apparatus, in particular to an electric heating pipe and a cable connecting apparatus applied to electric heating appliances. The apparatus comprises a protecting sleeve, the lower end of which is sleeved on the upper section of the pipe shell of the electric heating pipe. The protecting sleeve and the pipe shell of the electric heating pipe are sealed through a sealing gasket. A current-conducting rod is drawn out of the pipe shell of the electric heating pipe and extends into the inner cavity of the protecting sleeve. The upper end of the protecting sleeve is provided with penetrating holes for cables. The end part of a cable penetrates a penetrating hole for cables into the inner cavity of the protecting sleeve before being connected to the current-conducting rod through an adapter connector. An insulation layer is provided between the internal wall of the protecting sleeve and the cables arranged at the inboard part of the internal wall, the adapter connector as well as the current-conducting rod. The upper end of the protecting sleeve is sealed by a choke plug. The sealed connecting part is provided with insulation protections by the introduction of a plurality of links to an electric heating pipe and a cable connecting apparatus, which substantially increases the sealing performance and insulation performance, and thereby, makes sealed the connecting part withstand high temperatures or high working pressures, and accordingly the service lifetime of the sealed connecting part is prolonged.
Description
Technical field
The utility model relates to the parts of electric heater unit, specifically is a kind of electric heating tube and cable connecting arrangement that is used for electric heater.
Background technology
Traditional employing electric heating tube is the electric heater of electric heating unit, and the contact rod of its electric heating tube end is connected with outgoing cable by jockeys such as binding posts usually.But advance when electric heater uses the environment at some HTHPs, traditional jockeys such as binding post are difficult to satisfy instructions for use on sealing and insulating capacity, occur phenomenons such as electric leakage, short circuit easily, thereby have influenced the useful life of electric heater unit.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of good airproof performance, insulating capacity are strong, the electric heating tube and the cable connecting arrangement of long service life.
Electric heating tube of the present utility model and cable connecting arrangement include a sheath, and the lower end of sheath is enclosed within the shell epimere of electric heating tube, seals by sealing gasket between the shell of sheath and electric heating tube; The contact rod of drawing from the shell of electric heating tube extend into the sheath lumen, and sheath upper end is provided with cable and penetrates the hole, and cable end penetrates the hole from cable and penetrates to sheath lumen and by joint and be connected with contact rod; Jacket inner wall and be provided with insulating barrier between its inboard cable, joint and contact rod, the sheath upper end is sealed by plug.
Described jacket inner wall epimere is provided with a limited step, is pressed with a rubber stopper between plug lower end and the limited step, and above-mentioned cable passes from the through hole at rubber stopper center.
Described insulating barrier in the sheath is made of pulverous insulating packing.Have the filler entrance hole on the sidewall of described sheath, insulating packing is inserted the back by electric welding sealing filler entrance hole by the filler entrance hole.
Pass through welded closure between the shell outer wall of described sheath lower end and electric heating tube.
The utility model seals and insulating protection by the coupling part of a plurality of links to electric heating tube and cable, makes its sealing and insulating capacity improve greatly, can adapt to the operational environment of high temperature, high pressure, has prolonged its useful life.
