As widely known, carbon fiber is light in weight and has excellent tensile strength, elasticity, electrical conductivity and heat resistance as well as emitting far infrared ray. Therefore, in recent years, various kinds of heating products such as heat mats, A carbon fiber heating element formed by covering plural strands of thick carbon fibers with an insulating fabric instead of a conventional heating element made of copper or the like is widely used as a heating means.

In other words, various heating products using this carbon fiber heating element as heating means can be made lighter in weight compared to general heating products using general copper wire as a heating means, and can prevent the life of the heating element due to damage or breakage It is possible to eliminate the short-circuit or electric shock caused by these reasons, minimize the electromagnetic waves and radiate far-infrared rays to protect the user's health, maximize the energy efficiency through the high calorific value and radiant heat by infrared rays And it has many advantages.

However, since carbon fiber is made by heating and carbonizing in a glass fiber frame inert gas which is made of carbon, it breaks easily when bending because of high elasticity. Therefore, when bonding with general power supply line for power supply, The twist of the same two lines will make it impossible to make a connection.

Therefore, when connecting the carbon fiber heating element and the power line for the production of the carbon fiber heating product, it is necessary to peel off the covering portion of the connection portion of the carbon fiber heating element by necessity and merely repeatedly attach the chassis having the connecting portion of the general power supply line to the exposed carbon fiber outer surface And the outer surface of the connecting portion is wrapped and bound by an aluminum foil and a heat shrinkable tube so that the connection between the carbon fiber of the carbon fiber heating element and the core wire of the power supply line can not be completely made. The energy efficiency is lowered due to the increase of the power consumption by the carbon fiber heating element and the tensile strength of the binding portion is very weak and the carbon fiber heating element and the power line are easily separated even under the weak force. Related to tensile strength It is impossible to meet the legal regulations at all. Therefore, it is urgent to take countermeasures against illegal production of various kinds of heat-generating products using carbon fiber heating element as a heating element.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which: It will be omitted for the sake of clarity.

FIG. 1 is an exploded perspective view of the present invention. FIG. 2 is a perspective view showing the binding of the present invention. FIG. 1 is a perspective view showing a carbon fiber sheet 14 in a synthetic resin covering material 16 of a connecting portion 12 of a carbon fiber heating element 10, The core wire 22 of the connection portion 20 of the power line 18 is inserted between the carbon fibers 14 and the core wire 22 so that the connection portions 12 and 20 are connected to the sleeve 24, and the heat-shrinkable tube 26 is heat-shrinkably fixed to the outer surface of the sleeve 24. As shown in FIG.

According to another embodiment, the heat-shrinkable tube 26 is attached to the outer surface of the connecting portions 12 and 20 in order to obtain a higher binding force and prevent the carbon fiber heating body 10 from easily separating in the longitudinal direction of the power- And then the sleeve 24 is fitted to the outer surface of the heat-shrinkable tube 26 so that the heat-shrinkable tube 26 can be pressed and fixed. Of course, the heat shrinkable tube 26 can be fitted on the outer surface of the sleeve 24 to perform heat shrinkage fixing. In this case, the binding force in the longitudinal direction, that is, the tensile force can be increased by the heat-shrinkable tube 26 formed on the outer surface of the connecting portions 12 and 20. The carbon fiber heating element 10 or the power line 18 So that the binding force can be increased in the center direction. Also, a higher tensile force can be provided than when the heat shrinkable tube 26 is heat shrink-fitted to the outer surface of the sleeve 24 again.

The carbon fiber heating body 10 used in the present invention is formed by covering a plurality of carbon fibers 14 having a large thickness with a synthetic resin coating agent 16 such as silicone which is resistant to heat. The carbon fiber 14 and the synthetic resin covering material 16 are cut to have the same length so that the core wire 22 of the power supply wire 18 is inserted between the carbon fibers 14 in the synthetic resin covering material 16, do.

That is, since the carbon fibers 14 constituting the carbon fiber heating body 10 are formed of a plurality of strands having very small thicknesses, a clearance is generated between the carbon fibers 14 when they are covered with the synthetic resin covering material 16, A sufficient space for inserting the core wires 22 of the power supply line 18 between the carbon fibers 14 in the synthetic resin covering material 16 is ensured, The core wire 22 can be easily inserted and the connection with the carbon fiber 14 can be achieved.

The power line 18 used in the present invention is a general type in which the core wire 22 is covered with a synthetic resin covering material 28. The core wire 22 is formed in a plurality of strands and is connected to the carbon fiber heating body 10 It is preferable that a plurality of strands of the core wires 22 are closely inserted between the plurality of strands of carbon fibers 14 of the carbon fiber heating body 10 so that complete connection is established between the carbon fibers 14 and the core wires 22 .

The sleeve 24 is formed so that the outer surface of the connection portions 12 and 20 of the carbon fiber heating body 10 and the power line 18 are larger than the outer diameter of the carbon fiber heating body 10 and the power line 18, The carbon fiber heating body 10 and the power line 18 are fitted to the outer sides of the connecting portions 12 and 20 of the carbon fiber heating body 10 And the connection portions 12 and 20 of the power supply line 18 are firmly coupled to each other by the sleeve 24.

When the sleeve 24 is fitted to the outer surface of the heat-shrinkable tube 26 after the heat-shrinkable tube 26 is first fitted to the outer surface of the connecting portions 12 and 20 to increase the tensile force, the inner diameter of the sleeve 24 is It is needless to say that the thickness of the heat shrinkable tube 26 should be larger than the thickness of the heat shrinkable tube 26 when the heat shrinkable tube 26 is fixed to the outer diameter of the carbon fiber heating body 10 and the power line 18.

At this time, the slab 24 is fixed to the outer side of the outer surface of the synthetic resin covering material 16, 28 of the carbon fiber heating body 10 and the power line 18 or the outer side of the heat-shrinkable tube 26, There is no fear of damage or disconnection of the core wire 22 of the carbon fiber 14 or the power supply wire 18 of the antenna 10 and the connection portion of the carbon fiber 14 and the core wire 22 is pressed, It can be done perfectly.

 The heat-shrinkable tube 26 formed on the outer surface of the sleeve 24 is made of an insulating material and is generally made to contract by heat. The heat-shrinkable tube 26 is formed to be longer than the length of the sleeve 24 so that the sleeve 24 is completely wrapped do.

 The carbon fiber 14 constituting the carbon fiber heating element 10 is covered with the synthetic resin covering material 16 so that the core wire 22 of the power supply wire 18 is sandwiched between the carbon fibers 14 in the synthetic resin covering material 16 So that the entire connection between the carbon fibers 14 and the core wires 22 is achieved, thereby eliminating the possibility of connection failure.

According to another embodiment of the present invention, the core wire 22 of the power supply line 18 is not inserted between the carbon fibers 14 in the synthetic resin covering material 16, The core wire 22 and the carbon fiber 14 may be connected by spirally winding the carbon fiber 14 on the outer side.

An example of this is shown in Figs. 7 and 8. Fig.

7 and 8, the coated cloth 16 is peeled off so that the carbon fiber 14 is exposed to the carbon fiber heating element 10 for a predetermined length or longer, and the exposed carbon fiber 14 is coated with a predetermined adhesive tape 30). The adhesive tape 30 may have a width greater than the width of the carbon fibers 14 and may be selected to be of any type applied to the adhesive material.

The carbon fiber 14 is attached to the adhesive tape 30 at a predetermined position in the longitudinal direction of the adhesive tape 30 as shown in FIG. 7, and then the carbon fiber 14 is adhered The core wire 22 and the carbon fiber 14 can be connected by winding the gender tape 30 in a spiral shape on the outer diameter of the core wire 22 of the power supply wire 18 as shown in Fig. It goes without saying that the angle of the spiral wound around the core wire 22 by the adhesive tape 30 can be appropriately selected within a range in which the carbon fiber 14 is not broken by bending.

This binding is effective in that the adhesive material applied to the adhesive tape 30 and the adhesive tape 30 can bond the carbon fibers 14 and the core wire 22 to each other relatively firmly.

 After the connection between the carbon fiber heating body 10 and the power supply line 18, the connecting portions 12 and 20, that is, the connecting portions 12 and 20, are formed in the same manner as in the binding method of inserting the core wire between the carbon fibers 14, The sleeve 24 is inserted into the outer surface of the region where the adhesive tape 30 and the core wire 22 are bound and then the sleeve 24 is pressed and fixed between the connecting portions 12 and 20 to form the connecting portions 12 So that the connection between the carbon fibers 14 and the core wire 22 is more completely achieved by the pressing force in the process of pressing and fixing the sleeve 24. [ The sleeve 24 is attached to the outer surface of the heat-shrinkable tube 26 after the heat-shrinkable tube 26 is first fitted on the outer surface of the area where the adhesive tape 30 and the core wire 22 are bound as described above, It may be pressed and fixed.

The heat-shrinkable tube 24 is thermally shrunk to the outer surface of the sleeve 24 to provide a high tensile force by the double heat-shrinkable tube 26 and to securely fasten the sleeve 24 . The bonding between the carbon fiber heating body 10 and the power line 18 can be firmly performed without damage or disconnection of the carbon fibers 14 and the short circuit caused by disconnection of the carbon fiber heating body 10 and the power line 18 It is possible to eliminate the risk of electric shock and to satisfy the requirements of the related law on the tensile strength of the binding portion required as an electric heating product.
