[0028] See also Figure 1-5As shown, the utility model is a single-sided flexible circuit board, including a circuit board structure 1, a power layer 12 is arranged on the top surface of the substrate of the circuit board structure 1, and a surface layer 13 is arranged on the top surface of the power layer 12. A composite layer 14 is arranged on the bottom surface of the base layer 11, and a welding surface 15 is arranged on the bottom surface of the composite layer 14. Fixed structures are arranged on both sides of the circuit board structure 1, and a connecting groove 21 is arranged on the side of the fixing member 2 close to the circuit board structure 1, and the circuit board structure 1 extends into the connecting groove 21 of the fixing member 2. A setting groove 22 is provided on the side of the fixing member 2 away from the circuit board structure 1, and a card plate structure 4 and a baffle structure 5 are arranged inside the setting groove 22. A plurality of extrusion springs 3 are arranged on a side of the setting groove 22 close to the circuit board structure 1, and one end of the extrusion spring 3 is fixedly connected to the connecting plate 41 of the card plate structure 4. A contact plate 42 is fixedly provided on one side of the connecting plate 41 away from the extrusion spring 3, and the contact plate 42 has the same height as the connecting plate 41. The height of the contact plate 42 and the connecting plate 41 is the same as the height of the setting groove 22, so that the connecting plate 41 and the contact plate 42 are slidably limitedly connected in the setting groove 22. First toggle rods 44 are provided on both sides of the connecting plate 41, and one end of the first toggle rod 44 extends outside the setting groove 22; a magnetic strip 43 is provided on one side of the contact plate 42 away from the connecting plate 41, near the top surface, and the top surface and side surfaces of the magnetic strip 43 are exposed.

[0029] Each fixing member 2 is provided with a baffle structure 5 slidably, and a sliding groove 23 is provided at the top of each fixing member 2, and the sliding groove 23 is connected with the setting groove 22. The sliding plate 52 of the baffle structure 5 is slidably connected in the sliding groove 23, and a limiting plate 51 is fixedly provided at the bottom of the sliding plate 52, and the projection of the sliding plate 52 in the direction of the limiting plate 51 is included in the cross section of the limiting plate 51. A limiting groove 24 is provided at the bottom of the setting groove 22, and the limiting groove 24 is located directly below the limiting plate 51, and the shape of the limiting groove 24 is adapted to the shape of the upper limiting plate 51. A metal sheet is provided on one side of the limiting plate 51 close to the contact plate 42, and the metal sheet can be adsorbed with the magnetic strip 43. A card slot 53 is provided inside the sliding plate 52, and the shape of the card slot 53 is adapted to the shape of the contact plate 42. A metal sheet adsorbed with the magnetic strip 43 is provided on the upper inner wall of the card slot 53, and a second toggle rod 54 is provided at both ends of the sliding block.

[0030] When using this single-sided flexible circuit board, the fixings 2 on both sides of the circuit board structure protect the circuit board to prevent the side of the circuit board from warping, and at the same time reinforce the connection of the circuit board structure. The circuit board structure can be extracted through the fixing 2, and the sliding plate 52 is exposed from the top surface of the fixing 2, and the limit plate 51 at the bottom of the sliding plate 52 can prevent the sliding plate 52 from sliding out of the sliding groove 23. At the same time, the metal sheet on one side of the limit plate 51 is adsorbed with the magnetic strip 43 of the contact block, so that in the initial state, the sliding block is fixed, and the card slot 53 of the sliding block is exposed on the top surface of the fixing 2, which is convenient for the staff to directly extract the circuit board from the card slot 53 on the top surface. When the circuit board structure needs to be protected, the staff directly presses the sliding block, or actively toggles the first toggle rod 44 to make the magnetic strip 43 and the metal sheet of the limit plate 51 fall off. The sliding block slides downward, and the limit plate 51 slides into the limit groove 24, so that the slot of the sliding plate 52 moves into the setting groove 22. At this time, the connection plate 41 is subjected to the elastic force of the compression spring 3, driving the contact plate 42 to move into the slot 53 of the sliding plate 52. The top surface of the magnetic strip 43 on the surface of the contact plate 42 can be adsorbed with the metal sheet above the slot 53, so that the contact plate 42 is engaged and fixed to the sliding plate 52. The smaller the size of the fixing member 2, the better the integrity and stability. When it is necessary to release, the first toggle block and the second toggle block are toggled to move the connection plate 41 and the sliding plate 52 respectively.

[0031] The working principle of the utility model: the utility model is a single-sided flexible circuit board, by setting a card plate structure 4 and a baffle structure 5, the card plate structure 4 and the baffle structure 5 slide in the setting groove 22, so that the sliding plate 52 slides on the surface of the fixing member 2, so that the card slot 53 inside the sliding plate 52 is exposed, which is convenient for the staff to extract and move the fixing member 2 and the circuit board structure 1 through the card slot 53; when not in use, the sliding plate 52 slides into the inside of the fixing member 2, so that the moving plate and the contact plate 42 are moved into the card slot 53 by the elastic force to engage with each other, thereby reducing the volume of the fixing member 2 and increasing the integrity and stability of the structure; by setting a connecting plate 41, a first toggle rod 44 is set on both sides of the connecting plate 41, and the first toggle rod 44 can be exposed from the setting groove 22, so that when driving the contact plate 42 to move, it can be driven to move by directly toggling the first toggle rod 44, so that only one person is required to operate when moving.
