DETAILED DESCRIPTION
[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0020] like Figure 1-6A mobile phone communication linker flexible circuit board is shown, comprising a flexible circuit board body 4, the surface of the flexible circuit board body 4 is sleeved with two protective shells 2, one end of the two protective shells 2 is respectively installed with two first mounting blocks 7 and two second mounting blocks 17 by screws, the side central axes of the two first mounting blocks 7 and the two second mounting blocks 17 are on the same straight line, the sides of the two second mounting blocks 17 are both installed with fixed shafts 6 by screws, one end of the two fixed shafts 6 passes through the two first mounting blocks 7 and extends to one side thereof, and a positioning mechanism is provided between the two first mounting blocks 7 and one of the protective shells 2, and the positioning mechanism includes a limit gear 8 The limiting gear 8 is installed on the side of the first mounting block 7 by screws. The limiting gear 8 and the fixed shaft 6 are arranged coaxially. A second fixing block 10 is provided on one side of the limiting gear 8. A plurality of tooth blocks 9 are installed on the side of the second fixing block 10 by screws. The tooth blocks 9 are meshed with the tooth grooves of the limiting gear 8. The second fixing block 10 is installed on the end of one of the protective shells 2 by two elastic mechanisms. The elastic mechanism includes a movable tube 13. One end of the movable tube 13 is installed on the end of one of the protective shells 2 by screws. The other end of the movable tube 13 is movably connected with a fixing rod 12. One end of the fixing rod 12 is installed on the side of the second fixing block 10 by screws. A compression spring 11 is provided in a movable sleeve between the surfaces of the fixed rod 12 and the movable tube 13. The two ends of the compression spring 11 are respectively installed on the end of one of the protective shells 2 and the side of the second fixed block 10 by screws. The flexible circuit board body 4 is installed in the shell of the mobile phone communication linker and needs to be bent and installed. First, the second fixed block 10 is pushed. The second fixed block 10 pushes the fixed rod 12 to slide in the movable tube 13. At the same time, the length of the compression spring 11 shrinks, so that the second fixed block 10 drives the tooth block 9 to move out of the tooth groove of the limiting gear 8. Then, an external force is applied to one of the protective shells 2 according to the required bending angle. After the protective shell 2 is subjected to the torque force, it drives the second mounting block 17 and the fixed shaft 6 to rotate in the first mounting block 7, or the first mounting block 7 is subjected to the torque force and rotates on the surface of the fixed shaft 6, which facilitates the angle adjustment operation between the two protective shells 2, and then facilitates the bending operation of the flexible circuit board body 4.
[0021] Two flexible rubber sheets 3 are bonded between the ends of the two protective shells 2. The two flexible rubber sheets 3 are symmetrically arranged on both sides of the first mounting block 7. The two flexible rubber sheets 3 bend synchronously according to their own flexibility as the angle between the two protective shells 2 is adjusted, and are used to cover most of the gaps between the two protective shells 2, thereby achieving a certain degree of dust-proof effect on the flexible rubber sheets 3.
[0022] Two first fixing blocks 1 are installed on the two symmetrical surfaces of the two protective shells 2 by screws, and rubber pressure blocks 15 are placed on the symmetrical surfaces of the flexible circuit board body 4. The positions of the rubber pressure blocks 15 and the two first fixing blocks 1 correspond to each other. Two limiting holes 16 are provided on the surfaces of the two rubber pressure blocks 15. The two first fixing blocks 1 are provided with screw holes 14. The insides of the two screw holes 14 are threadedly inserted with studs 5. One end of the two studs 5 extends to the inside of the two limiting holes 16 respectively. In order to improve the protective shell 2 installed on the surface of the flexible circuit board body 4 Stability. After the protective shell 2 is sleeved on the surface of the flexible circuit board body 4, it is only necessary to rotate the eight studs 5 on both sides of the flexible circuit board body 4 in sequence. The studs 5 move spirally in the screw holes 14, and at the same time, the studs 5 push the rubber pressing blocks 15. After the surfaces of the two rubber pressing blocks 15 are pressed on the two symmetrical surfaces of the flexible circuit board body 4, the relative forces exerted by the two rubber pressing blocks 15 increase the friction between the rubber pressing blocks 15 and the surfaces of the flexible circuit board body 4, thereby improving the stability of the two protective shells 2 installed on the flexible circuit board body 4.
