Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an FFC heating belt according to the present invention. In this embodiment, the FFC heating tape includes a connection port 110, an insulating film, N connection conductors 120, and 2N end conductors 130; wherein:

the connection port 110 includes a first port and a second port, N end conductors 130 are disposed at the first port, N end conductors 130 are disposed at the second port, the first port and the end conductors 130 in the second port are disposed in a one-to-one correspondence to each other and connected by the connection conductor 120 to form a long conductor 140, each long conductor 140 is sequentially connected in series by the end conductor 130 to form a conductor 150, the end conductor 130 at one end of the conductors 150 in series is a head end conductor, the head end conductor is used as a first connection end of the FFC heating belt, the end conductor 130 at the other end of the conductors 150 in series is a tail end conductor, the tail end conductor is used as a second connection end of the FFC heating belt, and the insulation film wraps the connection conductor 120.

The connection port 110 is used for connecting with an external circuit, and the FFC heating belt is connected into the circuit through a head end conductor tail end conductor arranged in the connection port; a plurality of end conductors 130 are arranged in the first port and the second port, the end conductors 130 in the single connection port 110 are regularly arranged, and the end conductors 130 in the first port and the second port are correspondingly arranged; if the ordering starts with a head end conductor, that is, among the plurality of end conductors 130 connected in series, the head end conductor is the end conductor 130 (1), the end conductor 130 (1) is connected in series with the subsequent end conductor at a time until the tail end conductor, that is, the end conductor 130 (2N), the number of end conductors in the first port is the same as the number of end conductors in the second port.

It can be understood that, because the end conductors 130 are connected in series, and the end conductors 130 in different connection ports 110 are connected through the connection conductors 120, when the head end conductor and the tail end conductor are connected to the circuit and energized, part of the electric energy flowing through the end conductors 130 and the connection conductors 120 is converted into heat energy, so as to realize the heating function of the FFC heating belt.

It can be understood that, since the terminal conductors 130 and the connection conductors 120 are densely arranged and the FFC heating tape has flexibility, in order to ensure the independence between the connection conductors 120 and avoid a short circuit, the connection conductors 120 need to be independently arranged in the insulating film.

It should be noted that, the specific dimensions, the number, etc. of the terminal conductors 130 and the connection conductors 120 in the present invention may be set based on the actual application scenario and the requirement.

The end conductors 130 in the FFC heating belt are connected in series, so that when current is applied to the first connection end and the second connection end of the FFC heating belt, the end conductors 130 and the connection conductors 120 in the FFC heating belt can convert electric energy into heat energy, thereby realizing the heating function, applying the FFC to the field of temperature control, and increasing the application scenario of the FFC.

Further, referring to fig. 2, the end conductors 130 located at the same connection port 110 are connected in series by welding.

The end conductors 130 located at the same connection port 110 and having a series connection are connected in series by welding, and 160 in the drawing are welding points. Specifically, the welding mode includes but is not limited to tin-adding welding, auxiliary material-adding spot welding and laser welding, and besides, the connection can be realized by other feasible modes such as electroplated copper.

Further, the end conductors 130 include a plurality of intermediate end conductors connected in series between the head end conductor 130 (1) and the tail end conductor 130 (2N), each of two consecutive intermediate end conductors serves as a conductor unit 131, adjacent conductor units 131 are provided to different connection ports 110, and among the consecutive two conductor units 131, a rear intermediate end conductor in a front conductor unit 131 and a front intermediate end conductor in a rear conductor unit 131 are provided in correspondence in the connection ports 110.

Except the head end conductor 130 (1) and the tail end conductor 130 (2N), two continuous middle end conductors are used as conductor units 131, the middle end conductors 130 in the conductor units 131 are arranged at the same connecting port 110, adjacent conductor units 131 are arranged at different connecting ports 110, and in the same connecting port 110, the end conductors 130 are arranged according to serial numbers, the relative positions of the adjacent end conductors 130 in the corresponding connecting ports 110 are consistent, and the adjacent end conductors 130 are connected through the connecting conductors 120; for example, referring to fig. 3, where the end conductor 130 (1) is a head end conductor, the end conductor 130 (12) is a tail end conductor, the head end conductor 130 (1) is disposed at the first connection port 110, the end conductors 130 (2), (3) are disposed at the second connection port 110 as one conductor unit 131, the end conductor 130 (2) is disposed corresponding to the end conductor 130 (1) and is connected through the connection conductor 120, the end conductor 130 (4) is disposed at the first connection port 110 and is continuously disposed with the end conductor 130 (1) at the first connection port 110, the end conductor 130 (4) is disposed corresponding to the end conductor 130 (3) and is connected through the connection conductor 120, the end conductor 130 (5) and the end conductor 130 (4) are continuously disposed at the first connection port 110 as one conductor unit 131, and so on, the order of the end conductors 130 are continuously arranged at the first connection port 110 as the end conductors 130 (1), (4), (5), (8), (9), (12), and the order of the end conductors 130 are continuously arranged at the second connection port 110 as the end conductors 130 (2), (3), (6), (7), (…).

In other embodiments, the specific connection arrangement and the position arrangement may be selected based on the actual requirement based on the end conductors being in a series relationship, such as the series sequence of (1), (2), (4), (3), (5), (6), (8), (7), (9), (10), (12), (11).

Further, the number of the conductor units 131 is odd, and the head conductor and the tail conductor are disposed at the same connection port 110.

Or;

the number of the conductor units 131 is even, and the head-end conductor and the tail-end conductor are disposed at different connection ports 110.

It can be understood that, based on the actual application scenario, there are different requirements for the connection mode of the FFC heating belt; the installation manner of the medium-end conductor 130 of the FFC heating belt can be as follows:

when the number of the single connection ports 110 is even, for example, 4, the first connection ports 110 and the second connection ports 110 respectively include 4 end conductors 130, the end conductors 130 are respectively end conductors 130 (1) to (8) based on the serial connection sequence, wherein the end conductor 130 (1) is disposed at the first connection port 110, the end conductors 130 (2) and (3) are disposed at the second connection port 110, the end conductors 130 (4) and (5) are disposed at the first connection port 110, the end conductors 130 (6) and (7) are disposed at the second connection port 110, the end conductor 130 (8) is disposed at the first connection port 110, the end conductor 130 (1) is a head end conductor, and the end conductor 130 (8) is a tail end conductor, and the head end conductor and the tail end conductor are disposed at the same connection port 110.

When the number of the single connection ports 110 is odd, for example, 3, the first connection ports 110 and the second connection ports 110 respectively include 3 end conductors 130, the end conductors 130 are respectively end conductors 130 (1) to (6) based on the serial connection sequence, wherein the end conductor 130 (1) is disposed at the first connection port 110, the end conductors 130 (2) and (3) are disposed at the second connection ports 110, the end conductors 130 (4) and (5) are disposed at the first connection ports 110, the end conductor 130 (6) is disposed at the second connection ports 110, the end conductor 130 (1) is a head end conductor, the end conductor 130 (2) is a tail end conductor, and the head end conductor and the tail end conductor are disposed at different connection ports 110.

When the head-end conductor and the tail-end conductor are arranged at the same connecting port 110, the FFC heating belt can be connected through one connecting port 110, the FFC heating belt is convenient to realize, and meanwhile, the space requirement of the FFC heating belt in arrangement can be reduced; when the head-end conductor and the tail-end conductor are arranged at different connection ports 110, expansion is facilitated, for example, a plurality of FFC heating belts are connected in series, so that a heating function in a larger range is realized; in practical application, the specific positions of the head-end conductor and the tail-end conductor can be set based on practical application requirements.

Further, the connecting conductor 120 is made of alloy copper, and the end conductor 130 is made of alloy copper.

It is understood that the alloy copper has a higher electrical resistance than a single copper material, and thus generates a higher amount of heat when energized, so that the alloy copper may be used as the material for the connection conductor 120 and the end conductor 130 in order to increase the heat generating efficiency of the FFC heat generating belt. It should be noted that in other embodiments, other materials may be used for the connecting conductor 120 and the end conductor 130, such as single copper or other conductors. The material of the connection conductor 120 and the material of the terminal conductor 130 may be the same or different.

Further, the insulating film is a high temperature resistant film.

It can be understood that in the working process of the heating belt, the temperature is continuously increased or kept at a specific temperature, when the temperature is too high, the problems of melting, breakage and the like of a conventional insulating film can be caused, and in order to improve the reliability of the FFC heating belt, a high-temperature-resistant film is selected as the insulating film, so that the high working temperature can be borne while the insulating function is finished. It is understood that the material of the specific insulating film may also be selected based on the actual application scenario.

In addition, the present invention also protects a heat generating system, referring to fig. 4, which includes an FFC heat generating tape including a connection port 110, an insulating film, N connection conductors 120, and 2N end conductors 130, and a connection module 170; wherein:
