Description

Connecting structure of power line and carbon fiber heating wire of electric heating product

Technical Field

The utility model belongs to electric heat goods production field, concretely relates to connection structure of electric heat goods's power cord and carbon fiber heating wire.

Background

The power line and the heating element in the traditional electric heating product (such as an electric blanket and an electric heating pad) are both in the shape of metal wires, and are convenient to wind and connect and reliable to connect when being connected in a manual winding way in the production process; for the electric heating products using the carbon fiber heating wire as the heating element, if the connection is still performed by manual winding, the connection cannot be well wound and the dispersion phenomenon can occur. In order to overcome the problem, the method adopted at present is that a metal wire end of a power wire and a carbon fiber wire end of a carbon fiber heating wire are manually placed side by side and tightly clamped through a terminal copper sleeve, then the terminal copper sleeve is placed in a plastic insulating box in an adhering mode, glue is injected, and a cover plate is covered for sealing; however, the manual clamping method can cause poor contact between the metal wire end and the carbon fiber wire end due to insufficient force or misoperation of people, so that the ignition fault is caused, and adverse results are generated.

Disclosure of Invention

The utility model aims at providing an electric heating product's power cord and carbon fiber generate heat the connection structure of line to the metal thread end of reinforcing power cord and the contact conduction performance of the carbon fiber thread end of carbon fiber generate heat the line, avoid appearing the condition of contact failure.

The utility model discloses a connection structure of a power line and a carbon fiber heating wire of an electric heating product, which comprises a metal wire end of the power line, a carbon fiber wire end of the carbon fiber heating wire, a terminal copper sleeve and a plastic insulation box, wherein the metal wire end and the carbon fiber wire end are arranged side by side and are tightly clamped through the terminal copper sleeve, and the terminal copper sleeve is arranged in the plastic insulation box; and the metal wire end and the carbon fiber wire end in the terminal copper sleeve are coated with a conductive medium at the part which is adjacent in parallel, and the terminal copper sleeve and the conductive medium enable the metal wire end to be in contact conduction with the carbon fiber wire end.

Preferably, the conductive medium is carbon powder or conductive adhesive.

Preferably, the connection structure further includes an insulating sleeve, the insulating sleeve is bonded in the plastic insulating box, and the thermal shrinkage is fastened on the periphery of the terminal copper sleeve, the insulating layer of the power line close to the metal wire head, and the insulating layer of the carbon fiber heating wire close to the carbon fiber wire head (that is, the terminal copper sleeve, the insulating layer of the power line close to the metal wire head, and the insulating layer of the carbon fiber heating wire close to the carbon fiber wire head are all located in the insulating sleeve). Utilize insulation support to carry out the hot melt fastening, can prevent that terminal copper sheathing, power cord, carbon fiber heating wire from slipping relatively to reach fastening's effect more, and then strengthened insulating properties and fixity ability.

The utility model discloses a conductive medium is as supplementary thing that switches on, scribble conductive medium at the metal end of a thread in the terminal copper sheathing and carbon fiber end of a thread side by side adjacent position, reduced the discreteness of the silk bundle of carbon fiber end of a thread, terminal copper sheathing, conductive medium make metal end of a thread and carbon fiber end of a thread contact switch on to the contact conduction performance of joint has been strengthened, the condition of contact failure has been avoided appearing, the production of the trouble of striking sparks has also been avoided, thereby the whole security performance of electric heating products has been improved.
