Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Application principle of the invention is explained in detail with reference to the accompanying drawing.
Flexible circuit board as shown in Figure 1, the flexible circuit board include the flexible protective base 4 and sealing positioned at outer layer
Electric line plate 5 in flexible protective base 4, the flexible circuit board include bar shaped wiring board 1 and vertical with bar shaped wiring board 1
The insertion terminal 2 of connection, it is equidistant on the bar shaped wiring board 1 to be provided with several LED light 3, in the flexible wires
The junction of electric line plate 5 in the plate of road, the junction of LED light 3 and electric line plate and bar shaped wiring board 1 and insertion terminal 2
Perpendicular joints are provided with reinforcing mechanisms.
Wherein one layer of electric line plate 5, the electric line plate 5 of two sides is respectively arranged in the two sides of flexible protective base 4 of the present invention
Between the via hole 6 that passes through perpendicular to flexible protective base 4 connect, the upper and lower surface of the inner wall of the via hole 6 and outer ring applies
One layer is covered for connecting the metallic copper of two sides electric line plate 5.But in actual production process, it will usually due to metallic copper
Perfusion is uneven and results in 5 poor contact of electric line plate of two sides.Therefore a modification of the present invention scheme is at each
It is provided with two via holes 6 on link position, plays the role of dual fail-safe.
Another improvement project of the invention is that the both ends of the LED light 3 are passed through to two companies parallel with one another respectively
Wiring 501 is connected on electric line plate 5, and to avoid LED light 3, a connecting line 501 bends in the long-term use process
Life of product reduces caused by fracture, to improve the bend-resistance performance of flexible circuit board.
The top of the insertion terminal 2 is the metal wire exposed end 201 for removing flexible protective base 4, in insertion terminal 2
One layer of strengthening course 7 of back side docile, overlapping position herein are easy to happen fracture, therefore heretofore described reinforcing mechanisms is by institutes
It is overlapped length between the strengthening course 7 stated and metal wire exposed end 201 and is set greater than or is equal to 1.0mm, by increasing stress surface
Product is reinforced.
The bar shaped wiring board 1 and described is arranged in 4th kind of improvement project of heretofore described reinforcing mechanisms
It is inserted into the vertical angle junction of terminal 2.During using flexible circuit board, the position at the right angle is easiest to tear, from
And the metal wire in internally positioned electric line plate 5 is made to lose protection, it is broken.Therefore at this directly out close to right-angle side
The position of edge, the flexible guarantor in the curved metal line feeder 8 that the inside for being located at flexible protective base 4 is arranged, for preventing right angle from going out
It protects base 4 further to tear, while the metal reinforcing wires 8 are not in contact with the electric line plate 5.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
