Abstract

The utility model relates to an integrated cold and hot line joint for carbon fiber electric floor heating. A metal lead is connected onto a power line; the metal lead is connected with a carbon fiber heating line via a wiring terminal; and the connection place of the metal lead and the power line, and the connection end of the wiring terminal and the carbon fiber heating line are commonly sealed inside a machine mold pressing insulation body. Products which can directly arrange and connect a plurality of carbon fiber heating lines on the power line can be produced in a production workshop, in-situ laying can be carried out in the electric floor heating site, thereby omitting wiring operation of all joints, and avoiding glue gun sealing at each joint; the speed of the electric floor heating construction can be greatly improved; connection and sealing at the joints are reliable; electricity leakage phenomenon during the use process due to untight sealing can be prevented, and use security is greatly improved.

Description

The cold and hot line one of carbon fiber electrically floor heating joint

Technical field

The utility model relates to a kind of jointing of heating wire, specifically the cold and hot line one of a kind of carbon fiber electrically floor heating joint.

Background technology

Carbon fiber is nonmetallic materials, is universally acknowledged far infrared heating product, is applied to that as electric heating element the incomparable many superior functions of electric heating element such as metal, PTC are arranged in the electric floor heating with it.The quality of carbon fiber electrically floor heating line with heating function quality, the mode that often depends on the changes in temperature wire terminal, trace it to its cause mainly is because before and after the electric floor heating energising, the line body material structure of line with heating function can change a lot and dwindle such as heating expansion and cooling, and that cold pin partly changes is very little, so line with heating function makes the changes in temperature wire terminal partly produce the phenomenons such as oxidation, carbonization and mechanical strength reduction in the process of constantly heating, cooling easily.Up to the present, the blank area of following dual mode Treatment of Carbon line with heating function and plain conductor is adopted in the carbon fiber electrically floor heating usually: the one, and adopt insulating tape to twine when constructing at the scene or spray one deck insulating cement with FE Glue Gun and insulate; The 2nd, producer has added a heat-shrinkable T bush at blank area when manufacturing carbon fiber electrically floor heating heater wire.The mode of the first changes in temperature wire terminal not only needs to carry out site operation, and the reliability that its joint connects is relatively poor, can not well play the effect of waterproof, protection against the tide etc., produces easily the accident of electric leakage.Although the second way has been avoided the trouble of site operation, but producer need select suitable heat-shrink tube to be enclosed within the power lug when producing, then heat with heat gun, so that tightening, heat-shrink tube encases the effect that joint plays insulation, manufacture craft is also cumbersome, material cost is also relatively high, and the sealing of rear heat-shrink tube cover of long duration can descend, and has increased potential safety hazard.

The utility model content

The purpose of this utility model just provides the cold and hot line one of a kind of carbon fiber electrically floor heating joint, to solve the existing problem that the joint connection reliability is poor, site operation is loaded down with trivial details and coefficient of safety is low.

The utility model is achieved in that the cold and hot line one of a kind of carbon fiber electrically floor heating joint, be connected to plain conductor at power line, described plain conductor connects carbon fiber heating line by binding post, described plain conductor and with the common sealing-in of link of junction, described binding post and the described carbon fiber heating line of described power line in a machine-processed die stamping insulation body.

Described insulator is T-shaped structure, and described power line runs through the horizontal arm that connects of described insulator, and described carbon fiber heating line passes from the supporting leg of described insulator.

Be attached with the PVC insulating barrier at described carbon fiber heating line.

The utility model is that an end of the carbon fiber heating line end by binding post and plain conductor is joined, and the other end of plain conductor and the live wire of power line join, and by machine-processed die stamping insulation body blank area integral body are sealed at last; The other end of carbon fiber heating line adopts identical sealing-in form sealing-in in another one joint that the zero line with power line joins, and like this, just can make carbon fiber heating line form electric loop.Mode successively, can producing in workshop directly arranges on power line connects the finished product of some carbon fiber heating lines, need only on the spot laying in electric floor heating job site, both saved the operation of various terminal line, exempted again the glue rifle sealing-in of each joint, the speed of application of electric floor heating construction can significantly improve, and the connection of joint and sealing are reliable, prevented in the use procedure that because of the poorly sealed electric leakage situation that causes, the fail safe of use significantly improves.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, power line, 2, carbon fiber heating line, 3, plain conductor, 4, binding post, 5, insulator, 6, the PVC insulating barrier.

Embodiment

As shown in Figure 1, this one joint is that the live wire at power line 1 is connected to plain conductor 3, and the other end of plain conductor 3 joins by the end of binding post 4 with carbon fiber heating line 2.After connecting, by the mode of machine-processed mold pressing, with plain conductor 3 and with the common sealing-ins such as link of junction, binding post 4 and the carbon fiber heating line 2 of power line 1 in an insulator 5 by PVC material system.Consist of thus terminals of carbon fiber heating line 2, the other end of carbon fiber heating line 2 is pressed the same way as sealing-in in another one joint, what connect in this one joint is the zero line of power line 1, and the electric loop that forms thus carbon fiber heating line 2 connects.

Insulator 5 on the one joint can be made into T-shaped structure, and power line 1 runs through the horizontal arm that connects of insulator 5, and carbon fiber heating line 2 passes from the lower end supporting leg of insulator 5.Be attached with resistant to elevated temperatures PVC insulating barrier 6 at carbon fiber heating line 2, to improve insulation property.

Insulator 5 in the utility model also can have other modeling structures, and it is made that the insulating barrier of insulator 5 and wrap carbon fiber line with heating function 2 also can have a material of insulation property by polyolefin, fluoroplastics, polystyrene, polyester etc.Similar conversion so all drops within the protection range of the present utility model.
