Description

Technical Field

[0001] This invention relates to the field of electrothermal film technology, and in particular to an electrothermal film connector and an electrothermal film construction process. Background Technology

[0002] Electric heating film, a semi-transparent polyester film that generates heat when electricity is applied, is widely used in underfloor heating. It is typically made by coating a PET (polyethylene terephthalate) surface with conductive paste, then bonding it with conductive silver paste and copper strips, and finally sealing it with another layer of PET using adhesive and heat pressing to create a heating element. Insulating upper and lower encapsulation layers are then formed around the heating element using a bagging method or heat pressing. During installation, the conductive copper strips are connected to wires, converting electrical energy into heat energy, which is then radiated into the space. When installing electric heating film, the industry generally first connects the indoor electrical circuit... The method involves connecting the wires and the T-shaped cable with a pre-fabricated dedicated aviation plug at end A, and then connecting the metal terminal connected to end B of the aviation plug with the conductive copper strip at the edge of the heating film. Finally, the A and B ends of the aviation plug are plugged in to conduct electricity. This method has the following problems: 1. The T-shaped cable with aviation plug has a large diameter and is too long, which will result in a thick cement backfill layer, resulting in a lower usable floor height above ground; 2. The aviation plug and metal terminal are buried in the uncured cement, which is prone to circuit failure due to long-term acid and alkali corrosion and moisture intrusion. Repair also requires breaking through the ground surface layer and cement layer, which is extremely inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an electrothermal film connector and an electrothermal film construction process to solve the problems existing in the prior art, increase the usable floor height space above ground, reduce line faults, and facilitate maintenance.

[0004] To achieve the above objectives, the present invention provides the following solution: This invention provides an electrothermal film connector, including a clamping member, a conductive plate, and an encapsulation head. The clamping member is insulated and includes two parallel clamping plates and a connecting plate perpendicular to the two clamping plates. The connecting plate is disposed at the same end of the two clamping plates and is fixedly connected to each of the two clamping plates. A first through hole parallel to the clamping plates is formed on the connecting plate between the two clamping plates. The conductive plate is conductive, with one end connected to a wire and the other end passing through the first through hole and disposed parallel to the two clamping plates. The two clamping plates can move towards each other to clamp the copper strip at the edge of the electrothermal film and two encapsulation layers on both sides of the copper strip, and to connect and conduct the wire to the copper strip through the conductive plate. The encapsulation head is insulated and is sleeved on the outside of the end of the conductive plate connected to the wire to isolate the end of the conductive plate connected to the wire from the outside.

[0005] In some embodiments, a first fastener is also included, wherein a second through hole perpendicular to the clamping plate is provided on both clamping plates and the conductive plate, and a third through hole is provided on both the copper strip and the two encapsulation layers on both sides of the copper strip. The first fastener passes through the second through hole and the third through hole and can apply pressure from the side of each of the two clamping plates away from the conductive plate, so as to move the two clamping plates toward each other.

[0006] In some embodiments, a conductive connection portion is fixedly provided at one end of the conductive plate connected to the wire. The extension direction of the connection portion is parallel to the clamp plate. The cross-section of the connection portion is C-shaped. The opening of the connection portion is away from the conductive plate. The wire passes through the opening of the connection portion and is in communication with the connection portion.

[0007] In some embodiments, a second fastener is also included, wherein a fourth through hole is provided on one side of the wiring portion, and the second fastener passes through the fourth through hole to press the wire against the other side of the wiring portion.

[0008] In some embodiments, the encapsulation head extends parallel to the wiring portion, the cross-section of the encapsulation head is C-shaped, the opening of the encapsulation head is opposite to the opening of the wiring portion, and the encapsulation head can be sleeved on the outside of the wiring portion and abut against the side of the connecting plate away from the two clamping plates.

[0009] In some embodiments, the first fastener includes a sleeve and a column that cooperate with each other. One end of the sleeve is fixedly connected to a first end plate, and one end of the column is fixedly connected to a second end plate. The end of the sleeve away from the first end plate and the end of the column away from the second end plate run towards each other in the second through hole and the third through hole. When the sleeve is fitted onto the outer wall of the column, the first end plate and the second end plate can apply pressure from both sides of the two clamping plates away from the guide plate.

[0010] In some embodiments, the outer wall of the column is threaded to the inner wall of the sleeve, and the inner wall of the fourth through hole is threaded to the outer wall of the second fastener.

[0011] In some embodiments, the distance between the two clamping plates of the clamping member away from the conductive plate is 4-6 mm, and the distance between the two sides of the opening of the encapsulation head away from the conductive plate is 9-11 mm.

[0012] In some embodiments, the first fastener is made of an insulating material, and the second fastener is made of a conductive material.

[0013] This invention also provides an electric heating film construction process, comprising the following steps: extending the edge of the electric heating film to the baseboard of the wall; connecting a wire to one end of a conductive plate; passing the other end of the conductive plate through a first through hole and placing it between two clamping plates, and placing a copper strip and an encapsulation layer on one side of the copper strip between the conductive plate and one of the clamping plates, and placing an encapsulation layer on the other side of the copper strip between the conductive plate and the other clamping plate; moving the two clamping plates toward each other to clamp the copper strip of the electric heating film and the two encapsulation layers on both sides of the copper strip, and connecting and conducting the wire to the copper strip through the conductive plate; placing an encapsulation head on the outside of the end of the conductive plate connected to the wire to isolate the wire and the end of the conductive plate connected to the wire from the outside; and covering the electric heating film connector with a baseboard.

[0014] The present invention achieves the following technical effects compared to the prior art: This invention provides an electrothermal film connector and an electrothermal film construction process. During electroplating film construction, a wire is connected to one end of a conductive plate. The other end of the conductive plate passes through a first through hole and is positioned between two clamping plates. A copper strip and an encapsulation layer on one side of the copper strip are positioned between the conductive plate and one clamping plate, and an encapsulation layer on the other side of the copper strip is positioned between the conductive plate and another clamping plate. The two clamping plates move towards each other to clamp the copper strip of the electrothermal film and its upper and lower encapsulation layers. The wire is connected to the copper strip and conducts electricity through the conductive plate. An encapsulation head is fitted onto the outside of the end of the conductive plate connected to the wire to isolate the wire and the end of the conductive plate connected to the wire from the outside environment. Finally, a skirting board is used to cover the wire. The heating film connector is covered by clamps and conductive plates that hold the copper strip and its upper and lower encapsulation layers together, achieving conductivity and interconnection between the heating film and the copper strip. This eliminates the need for T-type cables with aviation plugs to connect the conductors and the heating film, reducing the thickness and length of the connector and making it smaller. The connector can then be placed in the baseboard junction box instead of in the ground, increasing the usable floor height and reducing acid and alkali corrosion and moisture intrusion, thus minimizing circuit failures. During maintenance, only the baseboard junction box needs to be removed, without breaking the floor, further improving ease of maintenance. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The purpose of this invention is to provide an electrothermal film connector and an electrothermal film construction process to solve the problems existing in the prior art, increase the usable floor height space above ground, reduce line faults, and facilitate maintenance.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 This embodiment provides an electrothermal film connector, such as... Figures 1-4As shown, the device includes a clamping member 1, a conductive plate 2, and an encapsulation head 3. The clamping member 1 is insulated and includes two clamping plates 11 arranged parallel to each other, and a connecting plate 12 perpendicular to the two clamping plates 11. The connecting plate 12 is located at the same end of the two clamping plates 11 and is fixedly connected to the two clamping plates 11 respectively. A first through hole parallel to the clamping plates 11 is opened on the connecting plate 12 between the two clamping plates 11. The conductive plate 2 is conductive. One end of the conductive plate 2 is connected to a wire, and the other end of the conductive plate 2 passes through the first through hole and is arranged parallel to the two clamping plates 11. The two clamping plates 11 can move towards each other to clamp the copper strip and the upper and lower encapsulation layers of the copper strip at the edge of the heating film, and connect the wire to the copper strip and conduct electricity through the conductive plate 2. The encapsulation head 3 is insulated and is sleeved on the outside of the end of the conductive plate 2 connected to the wire to isolate the end of the conductive plate 2 connected to the wire from the outside. During the electroplating process, the wire is connected to one end of the conductive plate 2. The other end of the conductive plate 2 passes through the first through hole and is positioned between two clamping plates 11. The copper strip and the encapsulation layer on one side of the copper strip are positioned between the conductive plate 2 and one clamping plate 11, and the encapsulation layer on the other side of the copper strip is positioned between the conductive plate 2 and the other clamping plate 11. The two clamping plates 11 are moved towards each other to clamp the copper strip of the electrothermal film and its upper and lower encapsulation layers. The wire is connected to the copper strip and conducts electricity through the conductive plate 2. The encapsulation head 3 is fitted onto the outside of the end of the conductive plate 2 connected to the wire to isolate the wire and the end of the conductive plate 2 connected to the wire from the outside. Finally, the electrothermal film is covered with a skirting board. The membrane connector uses clamping plates 11 and conductive plates 2 to hold the copper strip and its upper and lower encapsulation layers, achieving mutual conductivity between the conductive and heating copper strips. This eliminates the need for T-type cables with aviation plugs to connect the conductors and the heating copper strips, reducing the thickness and length of the connector and making it smaller. The connector can be placed in the baseboard junction box instead of the ground, increasing the usable floor height and reducing acid and alkali corrosion and moisture intrusion, thus minimizing circuit faults. During maintenance, only the baseboard junction box needs to be removed, without breaking the ground, improving ease of maintenance.

[0021] In some embodiments, the electrothermal film connector further includes a first fastener 4. A second through hole 41 perpendicular to the clamping plate 11 is provided on both clamping plates 11 and the conductive plate 2. A third through hole is provided on both sides of the copper strip and the two encapsulation layers. The first fastener 4 passes through the second through hole 41 and the third through hole and can apply pressure from the side of the two clamping plates 11 away from the conductive plate 2, so that the two clamping plates 11 move towards each other, thereby clamping the copper strip and the upper and lower encapsulation layers of the copper strip and making the wires conductive with the copper strip.

[0022] In some embodiments, a conductive connection portion 5 is fixedly provided at one end of the conductive plate 2 that connects to the wire. The extension direction of the connection portion 5 is parallel to that of the clamping plate 11. The cross-section of the connection portion 5 is C-shaped, and the opening of the connection portion 5 faces away from the conductive plate 2. The wire passes through the opening of the connection portion 5 and is conductive to the connection portion 5, thereby making the wire conductive to the copper strip of the heating film. In some embodiments, the heating film connector also includes a second fastener 6. A fourth through hole 61 is provided on one side of the connection portion 5. The second fastener 6 passes through the fourth through hole 61 to press the wire tightly onto the other side of the connection portion 5, thereby achieving conductivity between the wire and the connection portion 5, and further enabling conductivity between the wire and the conductive plate 2.

[0023] In some embodiments, the extension direction of the encapsulation head 3 is parallel to that of the wiring portion 5, the cross-section of the encapsulation head 3 is C-shaped, the opening of the encapsulation head 3 is opposite to the opening of the wiring portion 5, and the encapsulation head 3 can be sleeved on the outside of the wiring portion 5 and abut against the side of the connecting plate 12 away from the two clamping plates, so as to place the conductive wiring portion 5 and the part of the conductive plate 2 located on the side of the connecting plate 12 away from the two clamping plates inside the insulating encapsulation head 3 and the insulating clamping member 1, thereby reducing the impact of the external environment on the possible acid and alkali corrosion and moisture intrusion.

[0024] In some embodiments, the first fastener 4 includes a sleeve 42 and a column 43 that cooperate with each other. One end of the sleeve 42 is fixedly connected to a first end plate 44, and one end of the column 43 is fixedly connected to a second end plate 45. The end of the sleeve 42 away from the first end plate 44 and the end of the column 43 away from the second end plate 45 move towards each other in the second through hole 41 and the third through hole. When the sleeve 42 is sleeved on the outer wall of the column 43, the first end plate 44 and the second end plate 45 can apply pressure from the side of the two clamping plates 11 away from the conductive plate 2, so that the two clamping plates 11 move towards each other, thereby realizing the clamping of the copper strip and the upper and lower encapsulation layers of the copper strip, and making the wires conductive with the copper strip.

[0025] In some embodiments, the outer wall of the column 43 is threadedly connected to the inner wall of the sleeve 42. By changing the length of the threaded connection between the outer wall of the column 43 and the inner wall of the sleeve 42, the pressure applied to the side of each of the two clamping plates 11 away from the conductive plate 2 is adjusted. The inner wall of the fourth through hole 61 is threadedly connected to the outer wall of the second fastener 6. By tightening the second fastener 6, the second fastener 6 presses the wire tightly onto the other side of the wiring part 5, thereby achieving conductivity between the wire and the wiring part 5. In some embodiments, the first fastener 4 is made of insulating material. When the relative movement of the two clamping plates 11 is achieved through the first fastener 4 to clamp the copper strip and the upper and lower encapsulation layers, the first fastener 4 will not conduct with the conductive plate 2 or the copper strip, avoiding affecting the normal operation of the electrothermal film. The second fastener 6 is made of conductive material to achieve conductivity between the wire and the wiring part 5, thereby making the wire conduct with the conductive plate 2. In some embodiments, the first end plate 44 and the second end plate 45 are both regular octagonal end plates, so that the user can screw the sleeve 42 onto the outer wall of the column 43.

[0026] In some embodiments, the distance between the two clamping plates 11 of the clamping member 1 away from the side of the conductive plate 2 is 4-6 mm, and the distance between the two sides of the opening of the encapsulation head 3 away from the side of the conductive plate is 8-10 mm. Compared with the T-type cable with a 16 mm aviation plug commonly used in the installation of electric heating film, the electric heating film connector in this embodiment is thinner. In the length direction, the distance between the side edge of the encapsulation head 3 away from the conductive plate 2 and the side edge of the conductive plate 2 away from the encapsulation head 3 is 30-35 mm. Compared with the 270 mm length of the existing T-type cable with aviation plug from the conductor to the edge of the electric heating film, the electric heating film connector in this embodiment is shorter. This allows the electric heating film connector to be placed in the junction box of the skirting board instead of in the ground. On the one hand, this increases the usable floor height space above the ground, and on the other hand, it reduces the occurrence of acid and alkali corrosion and moisture intrusion, thereby reducing line faults. During maintenance, only the skirting board box needs to be opened, without breaking the ground, which improves the convenience of maintenance.

[0027] Example 2 This embodiment provides an electrothermal film construction process, including the following steps: Install the wires inside the baseboard junction box; extend the edge of the heating film to the baseboard of the wall. During construction, the heating film can be laid along the chamfer where the wall and the bottom meet, thus extending the edge of the heating film to the baseboard of the wall. At the connection point between the wire and the conductive plate 2, one end of the wire is connected to the conductive plate 2. Specifically, the insulation of the wire that needs to be connected to the heating film connector is stripped off, the wire is passed through the opening of the wiring part 5, and the wire is pressed against the other side of the wiring part 5 by the second fastener 6 through the fourth through hole 61 to achieve the connection between the wire and the conductive plate 2. The other end of the conductive plate 2 is passed through the first through hole and placed between the two clamping plates 11. The copper strip and the encapsulation layer on one side of the copper strip are placed between the conductive plate 2 and one clamping plate 11, and the encapsulation layer on the other side of the copper strip is placed between the conductive plate 2 and the other clamping plate 11. Pressure is applied from the side of each of the two clamping plates 11 away from the conductive plate 2 by the first fastener 4, so that the two clamping plates 11 move towards each other to clamp the copper strip of the electrothermal film and the two encapsulation layers on both sides of the copper strip, and the wire is connected to the copper strip and conduction is achieved through the conductive plate 2. The encapsulation head 3 is sleeved on the outside of the end of the conductive plate 2 that is connected to the wire, so as to isolate the wire and the end of the conductive plate 2 that is connected to the wire from the outside. The heating film connector is covered with a skirting board.

[0028] By using clamping plate 11 and conductive plate 2 to hold the copper strip and its upper and lower encapsulation layers, and achieving mutual conduction between the conductive and heating film copper strips, the use of T-type cables with aviation plugs to connect the conductors and heating film copper strips is eliminated. This reduces the thickness and length of the heating film connector, making it smaller in size. The heating film connector can be placed in the skirting box instead of in the ground, which increases the usable floor height space above ground and reduces the occurrence of acid and alkali corrosion and moisture intrusion, thereby reducing line faults. During maintenance, only the skirting box needs to be removed, without breaking the ground, improving the convenience of maintenance.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
