Description

Technical Field

[0001] The utility model relates to the technical field of electronic connection harnesses, and more specifically to an anti-vibration mechanism for a flat wire. Background Art

[0002] FFC cable Chinese translation: Flexible flat cable, the number and spacing of wires can be arbitrarily selected, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is most suitable for data transmission cables between mobile parts and motherboards, between PCB boards and in miniaturized electrical equipment, and is widely used in electric vehicles.

[0003] The battery module of an electric vehicle is composed of thousands of cells connected in series by conductive sheets. At the same time, the positive and negative electrodes of each battery cell need to be connected with a large current to provide the power required for the car to drive. At the same time, the voltage, current and temperature of each cell need to be monitored, and balance control and adjustment should be performed when the cell power is unbalanced. The sampling harness of the relevant signals is usually a flat cable.

[0004] The patent closest to the prior art is announcement number: CN215644877U, which discloses a flat wire with a fuse, comprising a flat wire body and a lead wire body. The flat wire body serves as a transmission line and has a thicker flat conductor. The lead wire body is led out from an exposure window opened on the flat wire body and has a fuse structure. When an abnormally large current passes through the circuit, the fuse structure will blow to protect the electronic components from being damaged by the abnormal current.

[0005] However, the curved structure of the fuse increases the resistance of the fuse. As the resistance increases, the fuse passes a constant current and is more likely to blow. However, the fuse of this patent is only modified from a rectangular structure to a curved structure. Therefore, the change in the curved structure is small and it is easy to be broken when it expands and contracts due to heat. At the same time, since it is used in vehicles, when the vehicle vibrates, the fuse is easily broken.

[0006] In view of this, the utility model proposes an anti-vibration mechanism for a flat wire that is shock-proof and not easily broken. Utility Model Content

[0007] The purpose of the utility model is to provide a shockproof and not easily broken flat wire anti-vibration mechanism, which can make the fuse shockproof and not easily broken by combining an S-shaped first anti-vibration structure 511 and a wavy second anti-vibration structure 512.

One end of the wavy second seismic structure 512 is connected to one end of the S-shaped first seismic structure 511 close to the first connecting body 52, and the other end is connected to one end of the S-shaped first seismic structure 511 close to the second connecting body 55. The combination of the S-shaped first seismic structure 511 and the wavy second seismic structure 512 is used to increase the resistance of the fuse structure 51. Due to the increase in resistance, the fuse structure 51 passes a constant current, which makes it easier to blow and has the effects of seismic resistance and tensile resistance.

[0009] Furthermore, the width of the wavy second earthquake-resistant structure 512 is smaller than the width of the S-shaped first earthquake-resistant structure 511, so that it is easier to fuse when the current is too large.

[0010] In some embodiments, there are multiple flat conductors, and the exposure windows 2 are opened at different positions on the insulating layer corresponding to different flat conductors. The first connector 52 is provided with multiple rows of welding areas 53, and each welding area 53 is provided with multiple welding holes 54. The solder penetrates into the flat conductor exposed by the corresponding exposure window 2 through the welding hole 54 of one of the welding areas 53 for welding, so that the non-welding ends of the lead wire body 5 are arranged neatly. The welding holes 54 can also gather and thicken the solder to increase the holding force of the solder.

[0011] Furthermore, each welding area 53 has at least three welding holes 54 .

[0012] Furthermore, there are at least three welding areas 53, and different welding areas 53 can be selected for welding.

[0013] Furthermore, the material of the insulating layer is polyurethane, which has the functions of high temperature resistance, insulation and pressure resistance.

[0014] Furthermore, the insulating layer further includes a reinforcement film, which covers both sides of the lead wire body 5 and extends above the insulating film and is bonded to the insulating film.

[0015] Furthermore, the outer surface of the reinforcing film is also provided with a wire body spray code 3, and each flat wire body 1 corresponds to a different wire body spray code 3 for marking the flat wire body 1, so that the required flat wire body 1 can be quickly selected.

[0016] In some embodiments, a plurality of temperature sensors 4 are connected to the flat wire body 1 to control the temperature of the flat wire body 1 .

[0017] Furthermore, the plurality of temperature sensors 4 are evenly spaced and arranged to ensure that the temperature sensors 4 are disposed at both ends of the flat wire body 1 .
