Description

Geothermal electric cable copper strip special crimping injection mo(u)lding connector

Technical field

The utility model relates to the connector of the Geothermal electric cable that a kind of indoor heating uses, specifically a kind of Geothermal electric cable copper strip special crimping injection mo(u)lding connector.

Background technology

Present stage, in China's indoor heating in winter mode mainly is heating installation and electric heating equipment, but at present, the advanced heating system of Gong Rening is to adopt the Geothermal electric cable heating technology in the world, promptly utilizes the pure resistance circuit, by heating element and intelligent temperature control system heating, this heating technology adopts underground heating mode, Inteldectualization Indoors management, charging is controlled at the branch family automatically, and have noiselessness, no flue dust, no waste gas, conserve space, have a narrow range of temperature, advantage such as non-maintaining, applied widely.The present environment-friendly type double shield Geothermal electric cable that uses; constitute by core, insulation jacket layer, foil shielding layer, wire guide catch net, external sheath layer; core is located at the center of insulation jacket layer; from inside to outside sheathed successively foil shielding layer and wire guide catch net between insulation jacket layer and external sheath layer; foil shielding layer mainly contains the effect of electromagnetic radiation shielding; the effect that also has simultaneously insulation; thereby make the insulation property of core better; the wire guide catch net mainly plays electromagnetic radiation shielding, guarantees that human body is not subjected to the injury of high-intensity magnetic field.When laying Geothermal electric cable; between heating core and the conductor wire be connected and wire guide catch net and earth connection between be connected; all be after adopting artificial straight tube crimping; twine adhesive waterproof tape again; make connector; the deficiency of this connector is: artificial crimping is insecure, easily come off, and the joint generates heat easily, easily aging, shortened the useful life of Geothermal electric cable.

Summary of the invention

The purpose of this utility model be to provide a kind of crimping firmly, single injection-molded, insulation be airtight, time saving and energy saving, make efficient and convenient, aging-resistant Geothermal electric cable copper strip special crimping injection mo(u)lding connector.

For reaching above purpose; the technical scheme that the utility model adopted is: this Geothermal electric cable copper strip special crimping injection mo(u)lding connector; by injection-moulded housing; the Geothermal electric cable termination; the conductor wire termination; the earth connection termination constitutes; Geothermal electric cable termination external ground electric heating cable; the external conductor wire in conductor wire termination; the external earth connection in earth connection termination; in the Geothermal electric cable termination, be provided with heating core termination and wire guide catch net termination; heating core termination is connected with the conductor wire termination is superimposed; wire guide catch net termination is connected with the earth connection termination is superimposed; it is characterized in that being provided with insulating barrier at the middle part of injection-moulded housing; after being connected with the conductor wire termination is superimposed, heating core termination is embedded in the injection-moulded housing of insulating barrier one side; wire guide catch net termination is embedded in the injection-moulded housing of insulating barrier opposite side after being connected with the earth connection termination is superimposed, and will generate heat core termination and the conductor wire termination section of being superimposed of insulating barrier separated fully with wire guide catch net termination and the earth connection termination section of being superimposed.The utility model is also implemented by following measure: the length of described heating core termination and the conductor wire termination section of being superimposed is 1-2 centimetre, Duan Shangshe copper strips crimping hoop is superimposed in generate heat core termination and conductor wire termination, make its contact closely, firmly, with will generate heat core termination and the crimping of conductor wire termination is one, makes the hot line joint; Wire guide catch net termination is wound in the seal wire bundle, the length of wire guide catch net termination and the earth connection termination section of being superimposed is 1-2 centimetre, the corresponding copper strips crimping of the Duan Shangshe hoop that is superimposed in wire guide catch net termination and earth connection termination connects closely, firmly it, makes the cold line joint; Copper strips crimping hoop on described two superimposed section is arranged side by side 2-5 respectively, with the copper strips press-connection machine directly in the termination superimposed section be pressed into one; Described injection-moulded housing and insulating barrier are by injection molding machine single injection-molded in the mould of injection-moulded housing.When making the utility model; need in special-purpose injection mold, to make; after heating core termination and conductor wire termination are superimposed; copper strips is wrapped in superimposed section of termination and compresses with the copper strips press-connection machine; make the hot line joint; after wire guide catch net termination and earth connection termination are superimposed; with the copper strips press-connection machine corresponding copper strips being wrapped in the termination goes up and compresses for superimposed section; make the cold line joint; in injection mold, be provided with the isolation thimble; hot line joint and cold line joint are put into injection mold; and lay respectively at the both sides that isolate thimble; hot line joint and cold line joint are separated fully, in injection mold, injection-moulded housing and insulating barrier single injection-molded are got final product with injection molding machine.

The beneficial effects of the utility model are: compare with present straight tube crimping, more firm with the copper strips crimping, housing is a single injection-molded simultaneously, it is airtight, anti-aging to insulate, make efficient and conveniently, time saving and energy saving, improved producer's operating efficiency, reduced labour intensity.
