Description

Technical Field

[0001] The utility model relates to the technical field of flexible flat cables, and particularly relates to a flexible flat cable structure with a secondary fixing effect. Background Technique

[0002] At present, a flexible flat cable is also called a Flexible Flat Cable (FFC). The number of wires and the spacing can be arbitrarily selected, making the connection more convenient, greatly reducing the volume of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as a data transmission cable between moving parts and the main board, between PCB boards, and in miniaturized electrical equipment.

[0003] In the prior art, the authorized publication number is: CN201167148Y, and the name is an improvement of the flexible flat cable group structure. The patent lies in that the structure strength of the round core wire in the flexible flat cable is better, and the round wire ends exposed outside the insulating film will not deform or turn up, so that it can be smoothly inserted into the holes corresponding to the connector seat body, and has the effect of facilitating assembly.

[0004] However, it is difficult to effectively fix the flexible flat cable during the connection process of this patent, and the flexible flat cable is prone to looseness during use. Content of the Utility Model

[0005] The technical problem solved by the utility model is that it is difficult to effectively fix the flexible flat cable during the connection process of the flexible flat cable, and the flexible flat cable is prone to looseness during use. The utility model provides a flexible flat cable structure with a secondary fixing effect.

[0006] To solve the above technical problem, a flexible flat cable structure with a secondary fixing effect provided by the utility model includes a circuit board. A connector and a flexible flat cable are installed on the upper part of the circuit board. A fixing mechanism is arranged on the upper surface of the circuit board. The fixing mechanism includes two groups of support rods arranged on the upper surface of the circuit board. The upper surface of the support rods is fixedly connected with a support plate. The upper surface of the support plate is inlaid with a first bearing. The inner ring of the first bearing is fixedly connected with a threaded rod. The outer surface of the threaded rod is threadedly connected with a threaded ring. The outer surface of the threaded ring is fixedly connected with two movable plates. The bottom surface of each movable plate is fixedly connected with a telescopic spring. The bottom end of the telescopic spring is fixedly connected with a cross plate. The bottom surface of each cross plate is fixedly connected with two push rods. The bottom end of the push rod is fixedly connected with a pressing plate.

[0007] Preferably, two sliding rings are inlaid on the upper surface of the support plate. A sliding rod is slidably connected inside each sliding ring. The bottom ends of the two sliding rods are respectively fixedly connected with the upper surfaces of the two movable plates. During the movement of the movable plate, the sliding rod can be pushed to slide inside the sliding ring, limiting the moving direction of the movable plate, effectively improving the stability of the movable plate during movement, and effectively avoiding the movable plate from being stuck due to skew during movement.

[0008] Preferably, a limit ring is fixedly connected to the top end of each sliding rod. The diameter value of the limit ring is greater than the diameter value of the sliding ring. The limit ring can be used to limit the sliding rod, effectively preventing the sliding rod from sliding out of the inside of the sliding ring during the sliding process, thereby avoiding affecting the normal sliding of the sliding rod inside the sliding ring.

[0009] Preferably, two vertical rods are fixedly connected to the bottom surface of the support plate. The bottom end of the vertical rod is fixedly connected to a stabilizing plate. The bottom end of the threaded rod is rotatably connected to the middle of the upper surface of the stabilizing plate, which can fix the bottom end of the threaded rod by using the stabilizing plate, making the threaded rod more stable during rotation, effectively preventing the threaded rod from swinging due to centrifugal force during rotation, thereby avoiding affecting the normal pushing of the threaded rod on the threaded ring.

[0010] Preferably, a rotating ring is fixedly connected to the top end of the threaded rod. Anti-slip lines are provided on the outer surface of the rotating ring. The user can rotate the rotating ring to drive the threaded rod to rotate by using the rotating ring, thereby facilitating the user to rotate the threaded rod. At the same time, the anti-slip lines can effectively increase the friction between the hand of the user holding the rotating ring and the rotating ring, avoiding the phenomenon of hand slipping.

[0011] Preferably, a soft pad is fixedly connected to the bottom surface of the pressing plate. The width of the soft pad is adapted to the width of the flexible cable. The flexible cable is fixed by using the pressing plate to push the soft pad. The soft pad has the flexibility to move, and can achieve soft contact between the pressing plate and the flexible cable, effectively preventing the flexible cable from being damaged due to the excessive hardness of the bottom surface of the pressing plate.

[0012] Preferably, an operation instruction board is fixedly connected to the upper surface of the support plate. The use instructions are engraved on the upper surface of the operation instruction board. During the installation process of the flexible cable, the user can read the use instructions on the operation instruction board to quickly master the correct operation method, effectively preventing the damage of this fixing mechanism due to improper operation.

[0013] Preferably, a mounting plate is fixedly connected to the outer surface of each support rod. The mounting plate is fixedly connected to the circuit board by screws. The installation and disassembly of this fixing mechanism can be realized through screws, which is convenient for the later maintenance and repair of this fixing mechanism.

[0014] Compared with the related art, the utility model has the following beneficial effects:

[0015] 1. By rotating the threaded rod, the utility model drives the threaded ring, so that the threaded ring drives the two movable plates to move downward. The movable plate pushes the cross plate and the push rod through the telescopic spring, so that the pressing plate moves downward to fix the pressing plate, and can effectively fix the flexible cable, effectively preventing the flexible cable from loosening during the connection process.

[0016] 2. By providing a slip ring, during the movement of the movable plate, the push rod can be pushed to slide inside the slip ring to limit the moving direction of the movable plate, effectively improving the stability of the movable plate during movement and effectively preventing the movable plate from getting stuck due to skew during movement. By providing a limit ring, the push rod can be limited by the limit ring, effectively preventing the push rod from slipping out of the inside of the slip ring during sliding, thereby avoiding affecting the normal sliding of the push rod inside the slip ring. By providing a vertical rod and a stabilizing plate, the bottom end of the threaded rod can be fixed by the stabilizing plate, making the threaded rod more stable during rotation and effectively preventing the threaded rod from swinging due to centrifugal force during rotation, thereby avoiding affecting the normal pushing of the threaded ring by the threaded rod.

[0026] Please refer to Figures 1-4 , a flexible cable structure with a secondary fixing effect, including a circuit board 1. A connector 3 and a flexible cable 8 are installed on the upper part of the circuit board 1. A fixing mechanism 2 is arranged on the upper surface of the circuit board 1. The fixing mechanism 2 includes two groups of support rods 202 arranged on the upper surface of the circuit board 1. An installation plate 10 is fixedly connected to the outer surface of each support rod 202. The installation plate 10 is fixedly connected to the circuit board 1 by screws 9. The installation and disassembly of the fixing mechanism 2 can be realized through the screws 9, which is convenient for the later maintenance and repair of the fixing mechanism 2.

[0027] The upper surface of the support rod 202 is fixedly connected to a support plate 2010. The upper surface of the support plate 2010 is fixedly connected to an operation instruction board 6. The upper surface of the operation instruction board 6 is engraved with an instruction manual. During the installation process of the flexible cable 8, the user can read the instruction manual on the operation instruction board 6 to quickly master the correct operation method, effectively avoiding damage to the fixing mechanism 2 caused by improper operation.

[0028] A first bearing 201 is embedded in the upper surface of the support plate 2010. The inner ring of the first bearing 201 is fixedly connected to a threaded rod 205. Two vertical rods 12 are fixedly connected to the bottom surface of the support plate 2010. The bottom ends of the vertical rods 12 are fixedly connected to a stabilizing plate 11. The bottom end of the threaded rod 205 is rotatably connected to the middle of the upper surface of the stabilizing plate 11, which can fix the bottom end of the threaded rod 205 by using the stabilizing plate 11, making the threaded rod 205 more stable during rotation, effectively avoiding the swing of the threaded rod 205 due to centrifugal force during rotation, and thus avoiding affecting the normal pushing of the threaded rod 205 on the screw ring 209.

[0029] The top end of the threaded rod 205 is fixedly connected to a rotating ring 5. The outer surface of the rotating ring 5 is provided with anti-slip lines. The user can rotate the rotating ring 5 to drive the threaded rod 205 to rotate, which is convenient for the user to rotate the threaded rod 205. At the same time, the anti-slip lines can effectively increase the friction between the hand of the user holding the rotating ring 5 and the rotating ring 5, avoiding the phenomenon of hand slipping.

[0030] The outer surface of the threaded rod 205 is threadedly connected with a threaded ring 209. Two movable plates 208 are fixedly connected to the outer surface of the threaded ring 209. Two sliding rings 7 are inlaid on the upper surface of the support plate 2010. A sliding rod 13 is slidably connected inside each sliding ring 7. The bottom ends of the two sliding rods 13 are respectively fixedly connected to the upper surfaces of the two movable plates 208. During the movement of the movable plate 208, the sliding rod 13 can be pushed to slide inside the sliding ring 7, limiting the moving direction of the movable plate 208, effectively improving the stability of the movable plate 208 during movement, and effectively preventing the movable plate 208 from being skewed and jammed during movement.

[0031] A limit ring 4 is fixedly connected to the top end of each sliding rod 13. The diameter value of the limit ring 4 is greater than the diameter value of the sliding ring 7. The limit ring 4 can be used to limit the sliding rod 13, effectively preventing the sliding rod 13 from sliding out of the inside of the sliding ring 7 during sliding, thereby avoiding affecting the normal sliding of the sliding rod 13 inside the sliding ring 7.

[0032] A telescopic spring 203 is fixedly connected to the bottom surface of each movable plate 208. The bottom end of the telescopic spring 203 is fixedly connected to a cross plate 207. Two push rods 204 are fixedly connected to the bottom surface of each cross plate 207. The bottom end of the push rod 204 is fixedly connected to a pressing plate 206.

[0033] A soft pad 14 is fixedly connected to the bottom surface of the pressing plate 206. The width of the soft pad 14 is adapted to the width of the flexible cable 8. The pressing plate 206 is used to push the soft pad 14 to fix the flexible cable 8. The soft pad 14 has the flexibility to move, enabling soft contact between the pressing plate 206 and the flexible cable 8, effectively preventing damage to the flexible cable 8 due to the overly hard bottom surface of the pressing plate 206.

[0034] Anti-slip lines can be selectively formed on the bottom surface of the soft pad 14, which can effectively increase the friction between the soft pad 14 and the flexible cable 8, and effectively improve the fixing effect on the flexible cable 8.

[0035] In this application, chamfering treatments are performed on the corners of the support plate 2010 and the pressing plate 206, effectively preventing the corners of the support plate 2010 from rubbing against the user during the installation operation process, thereby avoiding injury to the staff.

[0036] The specific implementation process of this utility model is as follows: First, the staff docks the flexible cable 8 with the connector 3. Then, the staff rotates the threaded rod 205. The threaded rod 205 drives the threaded ring 209, causing the threaded ring 209 to drive the two movable plates 208 to move downward. The movable plate 208 pushes the cross plate 207 and the push rod 204 through the telescopic spring 203. The push rod 204 is used to push the pressing plate 206, causing the pressing plate 206 to move downward to fix the flexible cable 8.

[0037] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
