At the same time, the flexible circuit board 1 has a certain electrical connection with the connection module 2, so as to achieve the effect of transmitting electrical signals.
[0029] The bottom of the flexible circuit board 1 is provided with a base 11, the interior of the base 11 is provided with a slide groove 12, the interior of the slide groove 12 is slidably connected to a slider 13 with lateral freedom of positioning, and a protective compartment 14 is fixedly installed above the slider 13.
[0030] The beneficial effect of adopting the above technical solution is that the interior of the protective chamber 14 is hollow, wherein a part of the middle section of the flexible circuit board 1 is located inside the protective chamber 14, so that the protective chamber 14 plays a certain protective role on the flexible circuit board 1, preventing scratches and the like during installation, which would affect the normal use of the flexible circuit board 1.
[0031] Among them, a fixed rod 15 is fixedly installed inside the protective compartment 14, a telescopic rod 16 is fixedly installed on the surface of the fixed rod 15, a spring 17 is sleeved on the outside of the telescopic rod 16, and a guide rod 18 is fixedly installed on the side of the telescopic rod 16 away from the fixed rod 15. Air holes 19 are opened at the upper and lower ends of the protective compartment 14.
[0032] The beneficial effect of adopting the above technical solution is that the telescopic rod 16 can be extended and retracted, and the flexible circuit board 1 located inside the protective compartment 14 is S-shaped, so that the flexible circuit board 1 located inside the protective compartment 14 can be pulled to extend and contract, achieving the effect of convenient organization and distance control.
[0033] The first reinforcing plate 4 is a rectangular parallelepiped, and the material of the first reinforcing plate 4 is relatively hard. The second reinforcing plate 8 is made of the same material as the first reinforcing plate 4 .
[0034] The beneficial effect of adopting the above technical solution is: the main function of the first reinforcing plate 4 and the second reinforcing plate 8 is to connect and support the two ends of the flexible circuit board 1. In addition to facilitating the pulling of the flexible circuit board 1, the flexible circuit board 1 can be effectively installed in the designated position to prevent the flexible circuit board 1 from bending and causing unevenness.
[0035] There are four connection chips 3 , and all four connection chips 3 are electrically connected to the flexible circuit board 1 through the connection module 2 . Meanwhile, all four connection chips 3 are rectangular parallelepipeds.
[0036] The beneficial effect of adopting the above technical solution is that after the connecting chip 3 is fixed through the flexible circuit board 1, the connecting chip 3 is welded with the external device, thereby completing the overall electrical connection, so that the flexible circuit board 1 can transmit electrical signals.
[0037] There are multiple mounting holes 5 and multiple copper cores 6 . The multiple copper cores 6 are respectively located inside the multiple mounting holes 5 , and the multiple copper cores 6 are all located inside the first reinforcing plate 4 .
[0038] The beneficial effect of adopting the above technical solution is that multiple copper cores 6 have a good heat dissipation effect. When the connection module 2 carries the connection chip 3 to connect with the external device, more heat will appear in the process of transmitting the electrical signal. Since the heat dissipation effect of the connection module 2 is poor, most of the heat inside the connection module 2 will be absorbed by the copper core 6, and then transmitted outward through the front end of the copper core 6, thereby achieving the effect of rapid heat dissipation.
[0039] There are two guide rods 18 , both of which are cylindrical and have relatively smooth surfaces, and both of which are in contact with the flexible circuit board 1 .
[0040] The beneficial effect of adopting the above technical solution is: since the flexible circuit board 1 located inside the protective chamber 14 is S-shaped, the flexible circuit board 1 located inside the protective chamber 14 is divided into two upper and lower inner cavities, and the two guide rods 18 are respectively located in the upper and lower inner cavities, which support the flexible circuit board 1.
[0041] Among them, there are two fixed rods 15, both of which are located inside the protective compartment 14, and are respectively on the left and right sides of the center point of the protective compartment 14. There are four telescopic rods 16 and four springs 17, and the four telescopic rods 16 and four springs 17 are fixedly connected to the two fixed rods 15 and the two telescopic rods 16.
[0042] The beneficial effects of adopting the above technical solution are: the four telescopic rods 16 and the four springs 17 are all located inside the protective compartment 14 and at the upper and lower cavities of the flexible circuit board 1 inside the protective compartment 14, and there are two telescopic rods 16 and two springs 17 inside each cavity. At the same time, the two telescopic rods 16 and two springs 17 located at the upper and lower cavities of the flexible circuit board 1 are distributed in opposite directions. When the distance of the flexible circuit board 1 needs to be adjusted, the two ends of the flexible circuit board 1 can be stretched in opposite directions, so that the telescopic rods 16 are contracted, so that the flexible circuit board 1 has an extension effect.
[0043] The working principle and use process of this utility model:
[0044] First, install the copper core 6 inside the first reinforcement plate 4. At the same time, install the protective chamber 14 above the base 11 through the sliding action of the slider 13 and the slide groove 12, and fix it with the screw holes 10 and bolts to install the second reinforcement plate 8 in the designated position.
[0045] At this time, the connection chip 3 is fixed to the external device, and the other part of the external device is inserted into the second reinforcing plate 8 to electrically connect the flexible circuit board 1, so that the flexible circuit board 1 has the effect of electrical signal transmission;
[0046] Secondly, when the flexible circuit board 1 needs to be stretched to control its length, since the flexible circuit board 1 is located in an S-shape inside the protective compartment 14, when the flexible circuit board 1 is stretched, the telescopic rod 16 will contract, so that the portion of the flexible circuit board 1 located inside the protective compartment 14 will be pulled out, thereby achieving the effect of controlling the distance. When the flexible circuit board 1 is pulled out too long, the spring 17 provides elastic force to slightly reset the flexible circuit board 1.
[0047] Finally, since the copper core 6 is located inside the first reinforcement plate 4, a large amount of heat will be generated after the connection chip 3 is connected to the telecommunications. Since the heat dissipation effect of the connection module 2 is poor, most of the heat inside the connection module 2 will be absorbed by the copper core 6 and then transmitted outward through the front end of the copper core 6, thereby achieving a rapid heat dissipation effect.
