Below in conjunction with accompanying drawing, illustrate the utility model.
Fig. 1 shows a kind of carbon fiber electrically heated syndeton 100, and it comprises power cable 101, carbon fiber heating rod 102 and the tripod joint 103 that connects power cable 101 and carbon fiber heating rod 102.Tripod joint 103 inside are provided with conductive connecting piece 104, in order to the conduction realizing between power cable 101 and carbon fiber heating rod 102, connect.In conjunction with Fig. 3, conductive connecting piece 104 runs through the inside that power cable 101 is directly inserted into carbon fiber heating rod 102, and the electric current by power cable 101 is input in carbon fiber heating rod, realizes the connection of circuit.Brace 104 not only has electric action also power cable 101 and carbon fiber heating rod 102 to be connected and fixed to effect.Brace 104 almost, all by power cable 101 and carbon fiber heating rod 102 parcels, the chance contacting with external environment, has guaranteed the security reliability of product.Even if the region that fraction is positioned at outside power cable 101 is also sealed by tripod joint 103.In technical scheme provided by the utility model, between each member, be almost seamless connection, fully guaranteed the insulated enclosure of electrical wire interface.
Now in conjunction with pure schematically Fig. 2 (a) and Fig. 2 (b), brace 104 of the present utility model is elaborated.Brace 104 comprises that fixture 201 and its length are obviously greater than the insert 202 of fixture 201.Fixture 201 and insert 202 include shape as the tip 203 of taper or arrow.Shape is conducive to the whole parts quick insertion of brace in tripod joint 103 and carbon fiber heating rod 102 as the tip 203 of taper or arrowhead form.
Refer again to Fig. 3, fixture 201 is fixed on brace 104 in tripod joint 103 in the way to insert.Fixture 201 is trapped in completely in tripod joint 103 under most advanced and sophisticated 203 effect, and brace 104 is fixed on to tripod joint 103 inside.Insert 202 is inserted into the inside of carbon fiber heating rod 102 to run through the mode of power cable 101, thereby realize power cable 101, be connected with the conduction between carbon fiber heating rod 102.The length of insert 202 is enough to the inside that makes insert 202 run through power cable 101 and be inserted into carbon fiber heating rod 102, with carbon fiber close contact, then, by the carbon fiber heating rod 102 of flowing through by the electric current of power cable 101, makes its heating.
According to a preferred implementation, fixture 201 is distributed in the both sides of insert 202 symmetrically, is conducive to brace 104 stress balances.Under the effect of fixture 201, brace 104 can be fixed in tripod joint 103 firmly.One or more inserts 202 are arranged on the centre of fixture 201.A plurality of inserts 202 can increase the contact area of brace 104 and carbon fiber 401, make brace 104 also power cable 101 is connected more firmly with carbon fiber heating rod 102 in performance electric action.In addition, a plurality of inserts 202 have improved the fracture resistance of brace 104, make brace under the effect of external force, difficult the fractureing of contact opening of power cable 101 and carbon fiber heating rod 102.Even if wherein some inserts are fractureed when mounted, due to the existence of other inserts, therefore, also can not affect the conduction connection function of brace 104, fully guaranteed the security reliability of product.
According to a preferred implementation, one or more inserts 202 be distributed in equally spacedly described fixture 201 between, and this spacing is in the scope of 1～2mm, guarantees between a plurality of inserts 209 independently of one another, do not contact mutually, guaranteed that power supply is stable.The length of fixture 201, in the scope of 2～5mm, guarantees that fixture 201 is embedded in tripod joint 103 completely and can not pierces through tripod joint when interior.
According to a preferred implementation, the length of insert 202, in the scope of 8～12mm, makes insert 202 at least can run through power cable 101 and fully contacts with carbon fiber 401.And in order to guarantee that brace 104 can firmly connect power cable 101 and carbon fiber heating rod 102, the length that insert 202 is embedded into carbon fiber 401 inside is at least greater than the joint length of tripod joint 103.The thickness of brace 104 is in the scope of 0～1mm, and the length of brace 104 is in the scope of 10～15mm.
According to a preferred implementation, in the situation that assembling completes, by the described connector 104 conducting electricity and high rigidity metal or alloy sheet is made, be embedded in the inside of described carbon fiber heating rod 102.Brace 104 is by making by metal or alloy sheet that conduct electricity and that have high rigidity, make in connecting the process of power cable 101 and carbon fiber heating rod 102, brace 104 can be press-fit into the inside of carbon fiber heating rod 102 under the effect of external force, and the shape that remains unchanged, can allow brace 104 under the effect of pressure apparatus, be pressed into smoothly carbon fiber heating rod 102 inside.
As shown in pure illustrative diagram 2 (b), the fixture 201 that is distributed in insert 202 both sides be in respectively with two planes of insert 202 place plane parallel in, make brace 104 in vertical view, be broken line type.Be designed to the brace 104 of structure like this, make in process of production, the fixture 201 of brace 104 does not conflict mutually with insert 202, if fixture 201 and insert 202 are arranged in same plane, be unfavorable for fixture 201 to be inserted into the both sides that are simultaneously also positioned at power cable 101 in tripod joint.
Refer again to Fig. 3, power cable 101 comprises the protection crust 303 of coating 302 and the parcel coating 302 of electric conductor 301, parcel electric conductor 301, makes electric conductor 301 be subject to the duplicate protection of coating 302 and protection crust 303.The distinctive double protection structures of power cable 101 of the present utility model, even if product of the present utility model is scratched in installation process, the phenomenon that also there will not be short circuit or coating to come off, fully guarantees the safe insulation performance of product.Carbon fiber heating rod 102 comprises carbon fiber 401 and the outer field insulating barrier 402 in the middle of being positioned at.Insulating barrier 402 is resistant to elevated temperatures polyester materials, and can not deform under carbon fiber electrically heated working temperature, thereby guarantees the reliability of product.
The utility model at least has the following advantages:
1, each member of the present utility model, all from the angle of safe insulation, guarantees the security reliability of product in all its bearings, and than other products, security reliability is higher.
2, the utility model is involved, and to have with the external world all material directly contacting are all nonferrous metal, its long service life.
3, carbon fiber electrically heated syndeton provided by the utility model, applied in floor heating, this floor heating can be directly used in laying, without again to electric wire and heater income joint connection in site, saved installation procedure, and the floor heating that this product is related, can directly lay cement mortar or floor tile, can accomplish waterproof, fire prevention.
