Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to an anti-static flexible circuit board for LED lamps of new energy vehicles. Background Art

[0002] Flexible printed circuit board, also known as FPC in the industry, is a printed circuit board made of a flexible insulating substrate. It has the advantages of free bending, winding, and folding. It is widely used in the field of new energy vehicles. Generally, flexible circuit boards are used in conjunction with new energy vehicle LED lights. Therefore, in the production process of new energy vehicles, flexible circuit boards need to be transferred to the processing table for processing.

[0003] During transportation, existing flexible circuit boards are generally stacked and transported in groups, which causes friction between the flexible circuit boards during transportation and easily generates static electricity. The flexible circuit boards are easily affected by static electricity, which can easily cause device damage and shorten the service life of the flexible circuit boards.

[0004] According to the publication number: CN209330458U, an anti-static flexible circuit board for LTD lamps of new energy vehicles is provided, including a flexible circuit board body, an anti-static layer, and a connecting part. The connecting part includes a first connecting block, a second connecting block and a third connecting block. The anti-static layer includes a first anti-static layer and a second anti-static layer; a first anti-static layer is provided on the lower surface of the flexible circuit board body, and a second anti-static layer is provided on the upper surface. The first anti-static layer is fixedly connected to the first connecting block on both sides, the second connecting block is fixedly connected to the second connecting block on both sides of the flexible circuit board body, and the third connecting block is fixedly connected to the second anti-static layer on both sides; the first connecting block is clamped with the second connecting block, and the second connecting block is clamped with the third connecting block. By arranging an anti-static layer with a connecting part on the surface of the flexible circuit board, electrostatic interference caused by static electricity generated by friction during transportation on the flexible circuit board is avoided. The anti-static layer consists of two layers, the upper and lower layers, and the anti-static effect is better. By arranging the connecting part, the structure is simple, which is convenient for disassembly and installation of the anti-static layer.

[0005] According to the anti-static flexible circuit board of the new energy vehicle LTD lamp introduced above, the flexible circuit board is protected by the anti-static structure, but the position of the anti-static structure after assembly cannot be positioned, resulting in the separation of the anti-static structure during transportation, causing the stacked flexible circuit board to fall, resulting in a decrease in the anti-static effect of the flexible circuit board, reducing the working efficiency of the anti-static structure, and reducing the stability of the flexible circuit board during transportation. Therefore, we need to propose an anti-static flexible circuit board for new energy vehicle LED lamps. Summary of the Invention

[0025] Place the circuit board body 1 in the placement slot 3, cover it with the antistatic acrylic plate 6 and the antistatic base 2 combination, rotate the locking structures 7 at both ends to fix the position of the antistatic acrylic plate 6 and the antistatic base 2 after connection, then take the combined antistatic acrylic plate 6 and the antistatic base 2, drive the connecting block 8 to insert into the inner cavity of the connecting slot 9, so that the two groups of antistatic acrylic plates 6 and the antistatic base 2 are stacked, so that the flexible circuit boards are stacked, and then the position of the connecting block 8 and the connecting slot 9 after connection is positioned by the positioning structure 5, thereby improving the stability of the flexible circuit board during transportation, improving the antistatic effect of the flexible circuit board, and improving the working efficiency of the antistatic structure.

[0026] Connecting columns 10 are fixedly connected to the four sides of the bottom of the antistatic acrylic plate 6. A fixing groove 11 is provided at a position corresponding to the surface of the connecting column 10 and the surface of the antistatic base 2. The surface of the connecting column 10 and the inner cavity of the fixing groove 11 are inserted and slid. Through the cooperation between the connecting column 10 and the fixing groove 11, the antistatic acrylic plate 6 is taken to drive the connecting column 10 to be inserted into the inner cavity of the fixing groove 11, so that the antistatic acrylic plate 6 and the antistatic base 2 can be preliminarily combined.

[0027] The antistatic base 2 is composed of an antistatic nylon plate 21 and an antistatic polycarbonate plate 22. Antistatic foam 23 is filled between the antistatic nylon plate 21 and the antistatic polycarbonate plate 22. The antistatic nylon plate 21, the antistatic polycarbonate plate 22 and the antistatic foam 23 all have good antistatic effects.

The antistatic effect of the antistatic base 2 is improved by the cooperation of the antistatic nylon plate 21, the antistatic polycarbonate plate 22 and the antistatic foam 23.

[0028] An insulating sponge block is bonded to the lower surface of the anti-static acrylic plate 6. The surface of the insulating sponge block is equal to the cross-section of the placement groove 3. Through the setting of the insulating sponge block, the top of the flexible circuit board is squeezed, while avoiding damage to the flexible circuit board and preventing the flexible circuit board from shaking in the anti-static structure.

[0029] The locking structure 7 includes a mounting plate 71, which is fixedly connected to the outer surface of the antistatic acrylic plate 6. A threaded sleeve 72 is inserted and fixed on the surface of the mounting plate 71. The inner cavity of the threaded sleeve 72 is threadedly connected to a screw rod 73. One end of the screw rod 73 is fixedly connected to a knob 74. The other end of the screw rod 73 is rotatably connected to a block 75 by a rotating shaft. A slot 76 is provided on the surface of the block 75 at a position corresponding to the surface of the antistatic base 2. The surface of the block 75 is engaged with the inner cavity of the slot 76. Twisting the knob 74 drives the screw rod 73 to rotate. The screw 73 rotates through the threaded connection with the threaded sleeve 72, causing the screw 73 to push the block 75 toward the inner cavity of the slot 76. When the block 75 is combined with the slot 76, the position of the antistatic base 2 and the antistatic acrylic plate 6 after the combination is positioned. When the block 75 moves out of the inner cavity of the slot 76, the position of the antistatic base 2 and the antistatic acrylic plate 6 after the combination is released.

[0030] The surface of the block 75 is fixedly connected to a movable rod 12, and a through hole is opened at a position corresponding to the surface of the movable rod 12 and the surface of the mounting plate 71. The surface of the movable rod 12 is inserted and slid into the inner cavity of the through hole of the mounting plate 71, and the other end of the movable rod 12 is fixedly connected to the limiting block 13. Through the setting of the movable rod 12, the screw 73 is prevented from driving the block 75 to flip, thereby improving the stability of the block 75 when moving toward the slot 76.

[0031] The positioning structure 5 includes a threaded hole 51, one end of the threaded hole 51 extends to the inner cavity of the connecting groove 9, and a positioning hole 52 is opened at a position corresponding to the surface of the threaded hole 51 and the surface of the connecting block 8. The inner cavity of the threaded hole 51 is connected to a bolt 53 through a thread, and one end of the bolt 53 extends to the inner cavity of the positioning hole 52. Through the threaded connection between the bolt 53 and the threaded hole 51, the bolt 53 can be rotated to move up and down in the inner cavity of the threaded hole 51. When one end of the bolt 53 moves to the inner cavity of the positioning hole 52, the position of the connecting block 8 and the connecting groove 9 after combination is positioned. When the bolt 53 moves out of the inner cavity of the positioning hole 52, the position of the connecting block 8 and the connecting groove 9 after combination is released, and disassembly work can be carried out.

[0032] When in use, place the circuit board body 1 in the placement slot 3, cover the antistatic acrylic plate 6 and the antistatic base 2 combination, rotate the knobs 74 at both ends to drive the screw 73 to rotate, and the screw 73 rotates through the threaded connection with the threaded sleeve 72, so that the screw 73 pushes the block 75 to move toward the inner cavity of the slot 76. When the block 75 is combined with the slot 76, the position of the antistatic base 2 and the antistatic acrylic plate 6 after combination is positioned. When the block 75 moves out of the inner cavity of the slot 76, the position of the antistatic base 2 and the antistatic acrylic plate 6 after combination is released. Then take the combined antistatic acrylic plate 6 and the antistatic base 2 to drive the connecting block 8 and the connecting slot 9 to move. The two sets of antistatic acrylic plates 6 and the antistatic base 2 are combined to stack the flexible circuit boards. Finally, the bolt 53 is rotated. Through the threaded connection between the bolt 53 and the threaded hole 51, the bolt 53 is rotated to move up and down in the inner cavity of the threaded hole 51. When one end of the bolt 53 moves to the inner cavity of the positioning hole 52, the position of the connection block 8 and the connection groove 9 is positioned. When the bolt 53 moves out of the inner cavity of the positioning hole 52, the position of the connection block 8 and the connection groove 9 is released, and the disassembly work can be carried out, thereby improving the stability of the flexible circuit board during transportation, improving the antistatic effect of the flexible circuit board, and improving the working efficiency of the antistatic structure.
