Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, in an embodiment provided by the present disclosure, a flexible circuit board for a vehicle-mounted LED lamp includes a flexible board body 1, wherein a plurality of LED lamp beads 13 are fixed on the top of the flexible board body 1;
two groups of rubber rods 2 are arranged outside the LED lamp beads 13, a rubber protection plate 3 is fixed at the top end of each group of rubber rods 2, a plurality of grooves I4 are formed in the top of the flexible plate body 1, a rubber limiting rod 5 is fixed at one side, close to each other, of each group of rubber rods 2, a plurality of grooves II 6 are formed in the bottom of the flexible plate body 1, and the LED lamp beads 13 are protected by the structure, so that contact short circuit is prevented;
the front side and the back side of the flexible plate body 1 are respectively provided with a plurality of first anti-pulling lines 8, a plurality of first rubber fixing blocks 7 are fixed outside the plurality of first anti-pulling lines 8, a plurality of second anti-pulling lines 12 are arranged on two sides of the flexible plate body 1, a plurality of second rubber fixing blocks 14 are fixed outside the plurality of second anti-pulling lines 12, and the structure prevents the internal circuit of the flexible plate body 1 from being pulled and broken;
the inside of the flexible plate body 1 is fixed with four nuts one 9, the inside equal thread bush of the nut one 9 is equipped with a bolt 10, the top of the bolt 10 is fixed with a nut two 11, and the structure prevents the short circuit, and is convenient to transport.
In this embodiment, the rubber rods 2 are all sleeved in the flexible plate body 1, the rubber protection plates 3 are all movably sleeved in the first groove 4, and the rubber limiting rods 5 are all movably sleeved in the second groove 6.
In this embodiment, the second rubber fixing blocks 14 are both fixedly connected to the flexible board body 1, and the first rubber fixing blocks 7 are both fixedly connected to the flexible board body 1.
