Description

Heating film with riveting power terminal

The present invention relates to a heat generating film, and in detail, a plurality of rivets are configured in each power terminal configured to be divided into a plurality of layers or to apply current to a heat generating film using both surfaces or a plurality of substrates. It relates to a heat generating film having a riveting power supply terminal to improve the stability and reliability of the product.

In order to warm the cold floor in winter to get a good night's sleep, an electric mat or heating mat made of an electric cushion installed on a chair or other floor is used.

The heating mat is easy to operate because it operates using household power used in the home, it is easily generated by the supply of electricity, the temperature rises quickly, and the temperature control of the mat is easily performed by adjusting the power supplied. Recently, the use of heating mats has increased.

Conventionally, various techniques have been proposed with respect to the heating mat as described above. In particular, the conventional registered utility model No. 20-0272901 (announced on 20 April 2002) can control the temperature of the heating mat by measuring the current flowing in the heating wire to control the temperature of the heating mat that generates heat by supplying power. Some techniques have been proposed.

However, the conventional heating mat generates electromagnetic waves harmful to the human body. In particular, since most of the heating-related products used in homes and industries are currently using AC power, electromagnetic waves generated from the heating products can be shielded to some extent by covering the conductor, except for magnetic waves.

In addition, the heating mats according to the related art have a disadvantage in that stability is poor due to frequent connection failure between power terminals to which power is applied from the outside and power supply wirings. In general, the power supply wirings and the power supply terminals of the heating mat are electrically connected by bonding with a conductive adhesive or a tape or by tightening with a separate clip. As a result, the adhesive strength was low and the contact area was narrow, so that poor phenomena such as dropping occurred frequently and were exposed to the risk of fire due to sparks.

In addition, efforts have been made to produce lightweight heating mats, but lightweight heating mats have a high risk of deformation and breakage. The thinner and lighter the thickness, the more susceptible to the influence of the external force and the lower the fixed force, the greater the change in appearance according to the distortion or pressure, the greater the risk of breakage. Therefore, it is time to need a method that can increase durability and resilience while reducing the influence of distortion or external force while maintaining the lightweight, thin configuration.

The present invention to solve this problem is to be configured by riveting a plurality of rivets to each of the power terminals configured to be divided into a plurality of layers or the current is applied to the heating film using a double-sided or a plurality of substrates An object of the present invention is to provide a heating film having a riveting power terminal to improve the stability and reliability of the.

The heating film having a riveting power supply terminal of the present invention for solving this problem is a front substrate printed with a first silver heating wire printed with conductive ink and a back substrate printed with a second silver heating wire printed with conductive ink, the first silver heating wire A first power terminal formed of both ends of the + electrode and a-electrode to supply power, and a second power terminal formed of the both ends of the second silver heating wire to supply power and the electrode; And the rear substrate, the "+" electrode of the first power terminal and the "+" electrode of the second power terminal, the "-" electrode of the first power terminal and the "-" of the second power terminal. It can be achieved by including a plurality of rivets for riveting each of the electrodes to penetrate each of the electrodes to electrically connect the "+,-" electrodes of the front substrate and the rear substrate.

In addition, the heating film provided with a riveting power supply terminal of the present invention for solving the above problems is the first silver heating wire printed with a conductive ink on the front surface of the substrate, the conductive surface so as to correspond to the first silver heating wire on the back of the substrate A second silver heating line printed with ink, a first power terminal formed at both ends of the first silver heating line to supply power, and a first power terminal consisting of -electrode, and formed at both ends of the second silver heating line to supply power A second power terminal consisting of an electrode and a -electrode, a "+" electrode of the first power terminal and a "+" electrode of the second power terminal, and a "-" electrode of the first power terminal and the second power terminal It can be achieved by including a plurality of rivets for electrically connecting each of the "+,-" electrodes of the front substrate and the rear substrate by riveting each of the plurality of "-" electrodes to penetrate.

Therefore, according to the heating film having the riveting power supply terminal of the present invention, the current is applied to the heating wires configured to correspond to the front portion and the rear portion, respectively, so that the electromagnetic wave can be shielded while the current is applied to each power source. A plurality of rivets are configured to be riveted to the terminals, thereby improving the stability and reliability of the product.

If a plurality of rivets having two holes or more are formed in each of the power terminals, the adhesive strength of the power terminals and the wirings can be increased, and the contact resistance is decreased by increasing the contact area, thereby reducing the risk of fire due to sparks and the like. It can increase.

In particular, by configuring a plurality of rivets having two holes or more in each of the power supply terminals, the heating film formed by stacking two or more layers of substrates can be more firmly fixed. Since the heating films utilizing two or more layers of substrates may have deformations such as rotation or twisting of the stacked substrates, it is possible to increase durability by preventing deformations such as rotation or distortion through a plurality of riveting processes.

In addition, in the case of a heat generating film formed by stacking two or more substrates, the heat generating film may be further stably fixed by additionally configuring a lightweight thin copper plate or a metal layer as an adhesive layer between the substrates. The heat generating film may be deformed or damaged because its thickness is very thin. However, if the copper plate or metal layers are additionally formed as an adhesive layer between two or more layers, the heating film may be more firmly fixed according to its thickness.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The electromagnetic wave shield heating film shown in FIG. 1 includes a front substrate 110 on which a first silver heating wire 140 is printed with conductive ink, a back substrate 111 on which a second silver heating wire 141 is printed with conductive ink, a front surface, and The adhesive layer 112 which fixes and adheres the

back substrates

silver heating wires

140 and 141, respectively. It includes a plurality of rivets 150 for riveting each of the plurality of 120 and 121 to electrically connect each of the first and

second power terminals

120 and 121 corresponding to each other.

According to the present invention, the same effects of forming the first and second

silver heating wires

140 and 141 on the front and

rear substrates

110 and 111 are different from each other, and the current flowing through the reverse current to cancel the magnetic wave to eventually shield the magnetic wave. To get. In addition, a plurality of rivets having two holes or more are formed in each of the

power terminals

As the adhesive layer 112 for fixing and adhering the front and

back substrates

110 and 111, a lightweight thin copper plate or metal layer may be formed. In the case of the heating film formed by stacking two or more substrates, a lightweight thin copper plate or the like may be added as an adhesive layer between the substrates to prevent deformation or damage depending on its thickness.

2 and 3, the "+ power terminal 120a" and the "-power terminal 120b" are sequentially disposed on one surface of the front substrate 110, and the heating wire pattern is the "+" power terminal ( The pattern is connected from the side on which the surface 120a is formed to the opposite side and spaced apart by a predetermined distance, and then connected to the power terminal direction again, and the pattern is repeated to be connected to one end of the power terminal 120b.

That is, the pattern connected to the "+" power supply terminal 120a is spaced apart from each other to maintain a constant distance d from the left direction to the right direction-centering on the drawing, and again from the lower side to the upper direction of the figure, again in the right direction. Are connected in a left direction, and are connected to maintain a constant distance d in the upper direction of the drawing again, and are alternately repeatedly connected in a left direction to a right direction to "-" power terminal 120b. To flow the current. As a result, the heating line pattern constitutes a closed circuit in which the electrode terminals are sequentially arranged with the "+ power supply terminal 120a" and the "-power supply terminal 120b", and the sections are repeatedly formed.

The same pattern is formed on each of the

different substrates

110 and 111 so as to effectively block the magnetic waves, and when they are laminated, the magnetic waves are canceled by reversing only the direction of the flowing current. Therefore, when the

substrates

different substrates

110 and 111 in order to effectively block magnetic waves, and laminates the same pattern to block magnetic waves. Since
