Description

HEATING FILM FOR USING RIVETING ELECTRODE [0002]

[0001] The present invention relates to a heat generating film, and more particularly, to a heat generating film comprising a plurality of rivets formed by riveting a plurality of rivets on respective power terminals configured to apply current to a heat- So that the stability and reliability of the product can be improved.

In order to warm the cold floor in the winter and make it possible to take a good night's sleep, an electric mattress or an exothermic mat made of an electric cushion installed on a chair or other floor is used.

Since the heating mat works by using the home power source used at home, it is easy to operate, it is easily heated by the electricity supply, the temperature rises quickly, and the temperature control of the mat is easily performed by adjusting the supplied power source Recently, the use of heat mats has been increasing.

In the past, various techniques have been proposed for the heat-generating mat as described above. In particular, in the conventional registration utility model No. 20-0272901 (published on Apr. 20, 2002), the temperature of the heating mat can be controlled by measuring the current flowing through the heating line for controlling the temperature of the heating mat, Technology has been proposed.

However, the conventional heat generating mat generates harmful electromagnetic waves to the human body. Especially, since most of the heating related products used in home and industry are using AC power, electromagnetic waves generated from the heating products can be blocked to some extent by covering the conductor, but magnetic waves are an exception.

In addition, the heat-generating mats according to the related art have disadvantages in that the connection failure between the power supply terminals to which power is supplied from external sources and the power supply wiring lines is frequent and stability is poor. Generally, the power supply terminals and the power supply terminals of the heating mat are electrically connected by being bonded with a conductive adhesive, a tape or the like, or tightened with a separate clip or the like. Therefore, the adhesive strength is low and the contact area is small, so that defective phenomena such as the falling phenomenon frequently occur and the fire risk due to the spark is exposed.

In addition, although efforts have been made to manufacture a heat-generating mat as a lightweight and thin, a lightweight thin-type heat-generating mat has a great risk of deformation and breakage thereof. The thinner and lighter the thickness is, the more vulnerable it is to the influence of the external force and the lower the force to be fixed. Therefore, it is necessary to provide a method of increasing durability and restoring force while reducing the influence of distortion and external force while maintaining a lightweight thin configuration.

Registration Practical Utility Model No. 20-0272901 (published on Apr. 20, 2002)

In order to solve the above problems, the present invention provides a heat-generating film comprising a plurality of layers or a heat-generating film using two or more substrates, wherein a plurality of rivets are riveted to respective power terminals, And to provide a heat generating film having a riveting power source terminal for improving the stability and reliability of the heat generating film.

A heating film having a riveting power terminal according to the present invention includes a front substrate on which a first silver heating line is printed with a conductive ink, a rear substrate on which a second silver heating line is printed with a conductive ink, First and second power terminals for supplying power to each of the first and second silver heating lines, and a plurality of rivets for passing through the front and rear substrates and the first and second power terminals, And a plurality of rivets for electrically connecting the first and second power terminals of the first and second power terminals.

In order to solve the above problems, a heating film having a riveting power terminal of the present invention includes a first silver heating line printed with a conductive ink on a front surface of a substrate, a second silver heating line printed with a conductive ink so as to correspond to a first silver heating line, First and second power supply terminals for supplying power to each of the first silver heating line, the second silver heating line, the first silver heating line and the second silver heating line, a plurality of first rivets And a plurality of rivets electrically connecting each of the second power terminals.

Therefore, according to the heat generating film having the riveting power terminal of the present invention, it is possible to shield the electromagnetic wave by causing current to flow in the heating lines corresponding to the front face portion and the back face portion, respectively, The plurality of rivets are riveted to the terminals, thereby improving the stability and reliability of the product.

By providing a plurality of rivets having two or more holes at the respective power terminals, it is possible to increase the bonding strength between the power terminals and the wirings and reduce the contact resistance by increasing the contact area, thereby reducing the risk of fire due to sparks and the like, .

Particularly, by providing a plurality of rivets having two or more holes in each power supply terminal, the heat-generating film formed by stacking two or more substrates can be more firmly fixed. Since the heating films utilizing two or more layers of the substrate may be deformed such that the substrates are rotated or warped, deformation such as rotation or twisting through a plurality of riveting processes can be prevented and durability can be improved.

Further, in the case of a heat generating film formed by stacking two or more substrates, a lightweight thin copper plate, a metal layer, or the like may be additionally provided as an adhesive layer between the substrates to more stably fix the heat generating film. Since the heating film has a very thin thickness, there is a risk of deformation or breakage, but if a copper plate or metal layers are additionally formed as an adhesive layer between two or more substrates, the heating film can be more firmly fixed depending on its thickness.

1 includes a front substrate 110 on which a first silver heating line 140 is printed with a conductive ink, a rear substrate 111 on which a second silver heating line 141 is printed with a conductive ink, An adhesive layer 112 for fixing and adhering the rear substrates 110 and 111, first and second carbon layers 130 and 131 formed by stacking the first and second silver heating lines 140 and 141, and front and rear substrates 110 and 111 The first and second power supply terminals 120 and 121 are connected to the first and second silver heating lines 140 and 141. The first and second power supply terminals 120 and 121 are connected to the first and second silver heating lines 140 and 141, And a plurality of rivets 150 electrically connecting the first and second power terminals 120 and 121 to the first and second power terminals 120 and 121, respectively.

In the present invention, the first and second silver heating lines (140, 141) are formed on the front and rear substrates (110, 111) in the same manner and the flowing current flows in the reverse current to cancel the magnetic wave, . In addition, a plurality of rivets having two or more holes may be formed in each of the power terminals 120 and 121 to increase the bonding strength between the power terminals 120 and 121 and the wiring, and a heat generating film formed by stacking two or more substrates Fix firmly.

As the adhesive layer 112 for fixing and adhering the front and rear substrates 110 and 111, a lightweight thin copper plate or metal layer may be formed. In the case of a heat generating film formed by stacking two or more substrates, if a lightweight thin copper plate or the like is additionally provided as an adhesive layer between the substrates, deformation or breakage can be prevented according to the thickness thereof.

2 and 3, a "+ power source terminal 120a" and a "power source terminal 120b" are sequentially arranged on one surface of the front substrate 110, and the pattern of the heating line is connected to the "+" 120a are formed on the opposite sides of the power terminal 120b, and the patterns are connected to each other in the direction of the power terminal, and the pattern is repeatedly connected to one end of the power terminal 120b.

That is, the patterns connected to the "+" power supply terminal 120a are connected in the left-to-right direction around the center of the figure and spaced apart from each other so as to maintain a constant distance d, Quot; - "power terminal 120b by alternately repeating the connection from the left to the right in the upward direction of the drawing, So that the current flows. As a result, the heating line pattern constitutes a closed circuit in which the electrode terminals are sequentially arranged in the order of the "+ power source terminal 120a" and the "power source terminal 120b".

In order to effectively block the magnetic waves, the same pattern is formed on the respective substrates 110 and 111, and when they are laminated, magnetic waves are canceled by reversing only the direction of the current flowing. Therefore, when the substrates 110 and 111 are laminated together, the patterns must be formed to be coincident with each other. Therefore, the electrodes may be formed at the same position and the patterns may be formed in the same manner. Specifically, as shown in Fig. 3, a "+ power source terminal 121a" and a "power source terminal 121b" are sequentially arranged on one surface of the rear substrate 111, 120b "and the" power supply terminal 120a ".

Referring to FIG. 4, when the front substrate 110 and the rear substrate 111 are laminated, a pattern is superimposed like a mirror with respect to the adhesive layer 112. Therefore, in order to apply the reverse current printing patterning technique to the overlapped pattern, if the direction of the current flowing in each pattern is reversed, the magnetic waves are canceled.

As described above, in order to effectively block the magnetic waves, the present invention prints the same patterns on different substrates 110 and 111 and combines them to block the magnetic waves. Since electrodes are formed on each of the substrates 110 and 111 and reverse current patterning technology is used, electrodes of the substrates 110 and 111 may be formed by riveting a plurality of holes 110 and 111, To secure the characteristics of the film by connecting terminals, and to ensure stability when power is applied through the electrode part.

In particular, by forming a plurality of rivets 150 having two or more holes in each of the power terminals 120 and 121, the heat-generating film formed by stacking two or more substrates 120 and 121 can be more firmly fixed. The heat generating films utilizing the two or more layers of substrates 120 and 121 may be deformed such that the substrates 120 and 121 are rotated or twisted so that the substrates can be easily fixed through a plurality of riveting processes.

In the case of a heat generating film formed by stacking two or more substrates 120 and 121, a lightweight thin copper plate (or a gold material layer) or the like may be additionally provided as an adhesive layer 112 between the substrates, Can be fixed.
