Abstract
The utility model discloses a strip-shaped electric heating belt comprising a cable core and an insulation layer, wherein the insulation layer is wrapped on the outer surface of the cable core; a shielding layer made of conductive plastics is wrapped outside the insulation layer; and a plurality of metal wires are arranged between the insulation layer and the shielding layer. Since the structure is adopted, the strip-shaped electric heating belt has the advantages that 1. the shielding layer made of the conductive plastics has better shielding effect, can not be oxidized due to long-term use and has long service life; 2. more than 4 metal wires are arranged between the insulation layer and the shielding layer, which makes the grounding performance better; and 3. the production efficiency is improved and the product cost is reduced.
Description
Technical field
The utility model relates to the ribbon heater technical field, particularly a kind of banded ribbon heater.
Background technology
At present, use is in the ribbon heater of solar water heater upper hose, downcomer tracing thermal-insulating, and its basic structure is that the innermost layer is a cable core, and cable core is wrapped with plastic insulating layer, insulating barrier is wrapped with the screen by aluminium foil strip or metal wire knitted one-tenth, this shielding layer grounding.Because screen is aluminium foil or wire, easily oxidation of back is installed, cause performance reduction, easily short circuit, influence useful life; Shield effectiveness is bad simultaneously, and the production cost height.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of shield effectiveness of screen good, performance is good and the banded ribbon heater of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of banded ribbon heater, comprise cable core, insulating barrier, described insulating barrier is wrapped in the cable core outer surface, described insulating barrier is wrapped with the screen that is made of conductive plastics, is provided with many one metal wires between described insulating barrier and the screen.
Described wire is for more than at least 4.
The utility model adopts said structure, has the following advantages: 1, the screen of conductive plastics formation, and shield effectiveness is better, and can be because of long-time oxidation, the long service life used; 2,4 above wires being set between insulating barrier and screen makes the ground connection performance better; 3, improve production efficiency, reduced product cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a cross-sectional view of the present utility model;
In Fig. 1,1, cable core; 2, insulating barrier; 3, screen; 4, wire.
Embodiment
A kind of as shown in Figure 1 banded ribbon heater comprises cable core 1, insulating barrier 2, and insulating barrier 2 is wrapped in cable core 1 outer surface, and insulating barrier 2 is wrapped with the screen 3 that is made of conductive plastics.
Be provided with many one metal wires 4 between insulating barrier 2 and the screen 3.Wire 4 is copper wire, magnalium silk or copper-clad aluminum-alloy wire.Wire 4 can be determined concrete quantity as required for more than at least 4.The screen 3 that conductive plastics constitutes constitutes good grounding system with built-in metal silk 4, and its shielding and ground connection better effects if can be because of long-time oxidation, the long service life used.This ribbon heater production cost is lower simultaneously.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection range of the present utility model.
Claims (2)
