Description

A kind of distressed structure of overlength FPC light bar

Technical field

The utility model relates to car body light bar technical field, especially a kind of distressed structure of overlength FPC light bar.

Background technique

Light bar, which refers to, to be welded on LED light above copper wire or strip-shaped flexible wiring board with special processing technology, then is connected It connects with the mains luminous.FPC is a kind of with height reliability, and excellent flexible printed circuit is high with density, weight Gently, thickness is thin, the good feature of bending.In the design process of lamps and lanterns, length is longer, lamp bead arrangement is irregular when encountering or When person's step structure, it is necessary to use FPC as carrier.But FPC haves the defects that certain in welding, hardness itself is not It is enough, it is more soft, in transport and steel mesh brush tin, cross furnace and all there is certain difficulty, as FPC size lengthens, it is difficult also therewith plus Greatly.The headlight of car body, taillight, charging indicator light equal length have the shortcomings that in production and difficulty in 500mm or more: 1. exceeding patch device dimension limit, exceed steel mesh dimension limit, usually 500MM, increases production difficulty；2. being transported in production Defeated aspect needs to make expensive jig；3. FPC cost is much higher than FR4, the utilization rate of the FPC of irregular shape is low.

Existing straight strip type FPC light bar size is generally greater than 600mm, and super production capacity causes SMT producing line production efficiency to drop Low, fraction defective is excessively high.Existing straight strip type FPC, which can not be successfully, to be locally bent, can not wide-angle multi-angle the installation side change FPC To, bending region be easy to tear, generally use connector connection, due to plate connector for substrate is deposited in end, need to design Boss places interface device, leads to the different row of FPC shape, off-gauge rectangular, space utilization rate is poor in production.

For example, Authorization Notice No. is CN207732124U in Chinese patent document, authorized announcement date is on August 14th, 2018 The utility model patent of disclosed entitled " FPC connector and its combo architectures with FPC route ", a kind of FPC of this application connect Device and its combo architectures with FPC route are connect, the FPC connector is that affiliated multiple terminals are arranged in front two rows, with In the case where connector width is restricted and number of terminals is fixed, between expansion adjacent both ends separated by a distance, to reduce The degree that electromagnetic coupling is interfered occurs between adjacent both ends when transmit signal, is also added among two rows of terminals Between electrical shield to cooperate with upper cover electrical property shield to provide the shielding environment in various dimensions space, to exist to reduce two rows of terminals The degree of electromagnetic coupling interference occurs when transmitting signal each other.Disadvantage is that combo architectures are fixed by frame, Several electrical shielded lines are equipped with, light bar intracorporal for vehicle is propagated using light is influenced；Structure is complicated, when using in car body Vehicle body space is tied up, car body Simplicity in Design is unfavorable for；Heat dissipation is not easy.

Therefore, the distressed structure for designing a kind of overlength FPC light bar of suitable car body light bar application is just necessary.
