Description

Novel FFC with fuse

Technical Field

The utility model relates to a flexible cable technical field specifically indicates a set up the fuse on it, be used for the FFC on the new forms of energy power battery.

Background

The FFC is a Flexible Flat Cable, which is an abbreviation of a Flexible Flat Cable and is commonly used in electronic products, the current FFC is composed of two insulating films and a conductor layer arranged between the two insulating films, and a fuse is not needed to be arranged when the FFC is used in the electronic products.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the present invention provides a novel FFC for use in a new energy power battery and having a fuse.

In order to achieve the above object, the utility model adopts the following technical scheme: the novel FFC with the fuse comprises an insulating film and a conductor layer arranged on one surface of the insulating film, wherein the conductor layer is composed of a plurality of metal strips which are parallel to each other, and the fuse is arranged at any position of at least one of the metal strips. The fuse can be formed by etching one or more or all of the metal strips of the conductor layer, and is generally thinner than the metal strips in order to function as a fuse.

Preferably, the fuse is integrally formed with the metal strip, i.e. the fuse is directly machined on the metal strip by an etching process, and thus the fuse is integrated with the metal strip.

Preferably, the fuse can be formed in any shape as long as the fuse is thinner than the metal strip, for example, the fuse is formed in a wave shape or a straight line shape.

Preferably, the fuse is formed by processing a metal strip by an etching process.

In order to prevent the fuse section from being directly exposed, the fuse structure further comprises an insulating adhesive film which is arranged on the other surface of the conductor layer and used for shielding the other surface of the conductor layer and the fuse.

The beneficial technical effects are as follows: etching any one section of one or more or all of the metal strips on the conductor layer can process one or more or the same number of fuses as the metal strips, and specifically, in general, the fuses are thinner than the metal strips in order to realize the function of the fuses. Thereby, through set up the fuse on current FFC, improved FFC's security, will the utility model discloses a when FFC is used for new forms of energy power battery, need not to set up the fuse in other positions, be favorable to optimizing power battery's internal line design.

Detailed Description

In order to make the technical field of the present invention better understand, the present invention is further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, an embodiment of the present invention provides a novel FFC with a fuse, including an insulating film 1, a conductive layer 2 disposed on one surface of the insulating film, wherein the conductive layer 2 is composed of a plurality of metal strips 201 parallel to each other.

As shown in fig. 3, a fuse 3 is provided at any position of at least one of the metal strips.

Here, the number of the metal strips 201 is different according to different uses of the FFC, and therefore, the plurality of metal strips herein should be understood as two or more metal strips, which generally produce FFCs with different specifications according to the needs of users, and the number of the metal strips 201 is different when the specifications of the FFCs are different.

The metal strip 201 and the fuse 3 are integrally formed, that is, the fuse is directly formed on the metal strip through an etching process, so that the fuse 3 and the metal strip 201 are integrated, and the integral formation is understood herein to mean that the fuse is directly formed at a certain position of the metal strip 201, and the fuse 3 can be combined with the metal strip 201 without any connecting member or connecting process (such as welding).

For convenience of processing, if it is necessary to process the fuses 3 on several or all of the metal strips 201, the fuses provided on the respective metal strips 201 should be located at the same position.

The fuse 3 may be formed in any shape as long as the fuse 3 is thinner than the metal bar 201, for example, the fuse is formed in a wave shape or a straight line shape. In this embodiment, the fuse 3 has a wave shape as shown in fig. 3.

Preferably, the fuse 3 is obtained by processing the metal strip 201 by an etching process, the etching process is an existing mature process, and the fuse manufactured by the process has high yield and low processing cost.

As shown in fig. 4-5, the fuse module further includes an insulating film 4 disposed on the other surface of the conductive layer 2 for shielding the other surface of the conductive layer and the fuse 3.

As described above, one or several fuses 3 or the number of fuses corresponding to the number of metal strips can be formed by etching one or several or all of the metal strips 201 on the conductor layer 2, and the fuses 3 are generally thinner than the metal strips 201 in order to perform the function of the fuses. Thereby, through set up the fuse on current FFC, improved FFC's security, will the utility model discloses a when FFC is used for new forms of energy power battery, need not to set up the fuse in other positions, be favorable to optimizing power battery's internal line design.

In the above description, it should be noted that the terms "mounted," "connected," and the like are used in a broad sense, and for example, they may be fixedly connected, detachably connected, or integrally connected; the connection may be direct or indirect via an intermediate medium, and the connection may be internal to the two components.
