Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a carbon fiber-

The present invention relates to a structure for inserting means for preventing overheating in a heating element using carbon fibers.

The present invention relates to a structure for inserting means for preventing overheating in a heating element using carbon fibers. The heat generating sheet using carbon fiber is disclosed in Korean Patent Laid-open Publication No. 10-2007-0048103 entitled " heat generating sheet ".

However, in a heating sheet using carbon fiber, carbon fiber acts as a heating element, a heating element using carbon fiber is safer than other heating elements, and a risk of fire is less, but when a plurality of strands of carbon fibers are used at once, , Which may cause the user to feel uneasy about the possibility of a fire.

However, carbon fibers that are currently in use often do not have a device for controlling the temperature when the temperature rises to some degree. Most of them control the temperature depending on how much carbon fiber is used, and in the case of conventional bimetals, The use of the temperature control means is often not used because the bonding with the fiber is not easy and the manufacturing cost of the other temperature controlling means is greatly increased.

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the above-mentioned disadvantages, and it is an object of the present invention to provide a combined body using a bimetal which is widely used in the prior art.

In order to achieve the above-mentioned object, the present invention provides a carbon fiber connection structure that enables temperature control in a carbon fiber used as a heating element, wherein the carbon fiber connection structure includes a first fastener (12) A first coupling member 11 and a second coupling member 11 which are formed by sequentially projecting two fastening holes 13 and a third fastening hole 14 and protruding in a direction perpendicular to the longitudinal direction so as to wind an object placed on the main body, And a second tightening member having a fastening member for fastening the fastening member to the third tightening member of the first fastening member and a fourth fastening member for fastening the fastening member to the side of the fastening member, A carbon fiber strand may be bonded to the second tightening tool 13 and a bimetal may be connected to the fourth tightening tool so that the bimetal can be connected between the carbon fibers.

 The first fastening hole, the second fastening hole, the third fastening hole, and the fourth fastening hole may be combined by being rolled and squeezed.

The coupling member 16 has a pointed shape at one end and a columnar shape at the side surface, so that the third coupling member can be easily compressed and coupled.

A conductive adhesive agent may be added to the second tightening opening to increase the bonding force with the carbon fiber.

The second fastener may be formed by dividing the end portion into several strands and a plurality of grooves 18 may be formed in each strand so that carbon fiber strands are wound around the respective grooves 18 so as not to fall off.

The heating elements may be connected in parallel and operated by a battery.

According to the above-described invention, there is provided an effect of providing a carbon fiber heating structure which can be simply controlled in temperature without a separate temperature control device.

1 to 6 are diagrams showing an embodiment according to the present invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a diagram showing an embodiment according to the present invention. In the present invention, a separate connecting means is used to connect the carbon fiber to the bimetal.

That is, the heating wire made of carbon fiber is joined by using male and female coupling ports as shown in FIGS. That is, the first coupling unit 11 has a first tightening unit 12 and a second tightening unit 13 on the left side in order to couple a heating wire made of carbon fiber to the first coupling unit 11 as shown on the left When the heating wire is connected to the first tightening member, the first tightening member serves to catch the coating surrounding the heating wire. The second tightening member 13 serves to catch the heating wire made of carbon fiber on the inner side of the covering.

And the rightmost third fastener 14 serves to hold the fastener 16 when the fastener 16 of the second fastener 15 is engaged.

In particular, the carbon fiber heating element is held by the first tightening tool 12 and the second tightening tool 13 from the covering to the heating element inside, so that the carbon fiber heating element does not come off. In order to increase the bonding strength, The bonding agent may be applied to the sphere and the bonding force between the carbon fiber heating body and the first bonding body may be added.

The second coupling member 15 has a coupling member 16 having a sharp tip but a cylindrical shape at the front end and a fourth coupling member 17 similar to the first coupling member at the rear end. The fourth screw (17) allows one of the bimetallic connections to be connected.

The coupling port 16 has a pointed front end so as to be easily inserted into the third port 14 so that it can be easily inserted into the third port. In addition, the side surface of the coupling hole 16 has a cylindrical shape and can be tightly engaged with the third tightening hole 14.

After the second assemblies 15 are connected to both ends of the bimetal in this manner, the first assemblies 11 are connected to the carbon fiber heating wires to connect the bimetals between the carbon fibers to overheat the carbon fiber heating elements The supply of current is cut off so that the temperature does not rise above a certain temperature.

In the conventional carbon fiber heating element, even if a bimetal is connected to the bimetal, the temperature of the bimetal is often deteriorated and the temperature of the bimetal is deteriorated. In this case, The bimetal can be used while maintaining the bonding force of the thermostat, thereby achieving the same effect as mounting the temperature regulator while lowering the manufacturing cost.

Fig. 3 shows an example in which a heating mat is constructed in a serial connection manner using a joining structure according to the present invention. In the mat of FIG. 2, the heating lines are connected in series, and the bimetal is coupled using the coupling structure according to the present invention in the middle of the heating line, so that the heating does not occur.

FIG. 4 is a photograph of an actual product, showing a shape in which the bimetal and the first and second assemblies are combined. As shown in the figure, a bimetal was bonded between heating wires using carbon fibers, and a heat-shrinkable tube was used outside the first and second assemblies to surround the outer surface of the joint.

In addition, since the electricity used for the carbon fiber heating element uses direct current, there is no danger of short-circuit by merely using a heat-shrinkable tube. In case that even if a problem occurs, application of a nonconductive tape or insulating material to the outer surface of the heat- can do.

Fig. 5 shows another embodiment. Since the carbon fiber is formed of a very thin strand of yarn, there is a possibility that even if an adhesive is used for attaching to the first coupling, it may come off. In FIG. 4, as shown in FIG. 4, the second tightening tool is divided into several strands, grooves are formed in each strand, and carbon fibers are wound around the grooves formed in the respective strands so as to be joined. With this configuration, the carbon fiber does not escape from the second fastener, and the temperature can be controlled with a small cost.

In addition, the grooves formed in each strand may be formed to be staggered from each other to prevent the carbon fibers from being tangled with each other when the carbon fibers are bonded to the grooves.

Figure 6 shows yet another embodiment. 5, the heating elements using carbon fibers are connected in parallel instead of connecting in series. When direct current is applied to a carbon fiber heating element, the voltage drop becomes greater as the length of the wire becomes longer. In order to reduce the voltage drop, instead of connecting the carbon fibers in parallel, instead of putting the carbon fibers in a covered form on the yarn, The carbon fiber is inserted into the fabric and the fabric and the carbon fiber are integrated.

In this case, since it is not necessary to use a separate coating on the carbon fiber, the protrusion does not occur in the middle of the mat, so that it is easy to use and is easier to manufacture.

In addition, the product according to the present invention can operate with a battery even if it can draw only about 12 volts because of low electricity consumption. This is possible because it uses carbon fiber and is connected in parallel. It is possible to operate as long as 12 volts of DC can be discharged from a stationary battery.

Conventional mats can not cope with heat by using carbon fiber when carbon fiber is not used. Even if carbon fiber is used, since they are not connected in series, the voltage drop can not be overcome and it is not possible to use continuously. However, since the present invention uses a structure in which carbon fibers are used and connected in parallel, it is possible to use the battery only, which makes it possible to use it as a complete portable mat.

In addition, due to the coupling structure as shown in the present invention, power consumption at the joint portion is not large, and tight coupling is achieved, so that it can be operated as a battery.
