Description

Technical Field

[0001] This utility model relates to spliced ​​flexible circuit boards, and more particularly to a spliced ​​flexible circuit board. Background Technology

[0002] Flexible circuit boards are made of flexible insulating substrates, which can meet the design needs of smaller and higher density installations, helping to reduce assembly steps and enhance reliability.

[0003] For example, a type of spliced ​​flexible circuit board with authorization announcement number "CN211557635U" uses protective sleeves to protect both sides of the first and second flexible circuit boards. When the first and second flexible circuit boards are subjected to tensile force, the protective sleeves bear the stress instead, avoiding the problems of scratches and damage to the sides of traditional flexible circuit boards. This extends the service life of the spliced ​​flexible circuit board and improves its practicality. However, in the use of spliced ​​flexible circuit boards, the thin, flexible, and bendable nature of the boards, coupled with the screw-type fixing at the joints, increases the weight at the joints, making the boards prone to bending. Furthermore, the continuous downward force at the bent points can easily cause breakage over time, affecting the normal use of the flexible circuit board. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a spliced ​​flexible circuit board to prevent breakage of the flexible circuit board over time and ensure its normal use.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This spliced ​​flexible circuit board includes vertical strips, and a flexible circuit board structure is connected to the outer wall of the vertical strips. The flexible circuit board structure includes a flexible circuit board and a first connector. The front and rear sides of the flexible circuit board are respectively fixed to the outer walls of multiple vertical strips. The bottom of the flexible circuit board is fixed to the top of the first connector. A second connector is fixed to the top of the flexible circuit board. A circular block is fixed to the outer wall of the first connector. A circular opening is machined on the front of the second connector.

[0006] This feature allows the circular block behind the first connector at the bottom of the second flexible circuit board to engage with the circular opening on the front of the second connector at the top of the first flexible circuit board, preventing the two mating connectors from separating when the flexible circuit board is pulled.

[0007] To further improve the design, the inner wall of the circular opening is inserted into the outer wall of the circular block.

[0008] To further improve the design, multiple first connecting strips are fixed to the outer wall of the first joint.

[0009] In this configuration, the outer wall of the first connector is provided with a polyimide wrapping layer, and the outer wall of the polyimide wrapping layer is provided with a groove to allow the first connecting strip connected to the first connector to be exposed.

[0010] To further improve the design, multiple second connecting strips are fixed to the outer wall of the second connector.

[0011] In this design, the outer wall of the second connector is covered with a polyimide sheath, and the outer wall of the polyimide sheath has a groove to allow the second connecting strip connected to the second connector to protrude.

[0012] Further improvements include fixing the outer walls of the first and second joints to the outer wall ends of the vertical strips, respectively.

[0013] This feature, with its vertical bars, increases the connection points between the flexible circuit board and the first and second connectors, preventing breakage between the connectors and the flexible circuit board.

[0014] To further improve the design, curved plates are fixedly attached to the upper left and right sides of the first connector.

[0015] This feature, where the bending plate presses down on the second joint, prevents the second joint from warping.

[0016] The beneficial effects of this utility model are as follows: In this utility model, the first connector at the bottom of the second flexible circuit board in the flexible circuit board structure passes through the bent plate on the outer wall of the second connector at the top of the first flexible circuit board, and then the round block behind the first connector at the bottom of the second flexible circuit board is inserted into the round opening on the front of the second connector at the top of the first flexible circuit board. This can prevent the two mating connectors from separating when the flexible circuit board is pulled, and at the same time reduce the weight at the connection point, prevent the flexible circuit board from breaking over a long period of time, and ensure the normal use of the flexible circuit board.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] See attached document Figure 1-4 In this embodiment, a splicing flexible circuit board includes vertical strips 1. The outer wall of the vertical strips 1 is connected to a flexible circuit board structure 2. The flexible circuit board structure 2 includes a flexible circuit board 201 and a first connector 202. The front and rear sides of the flexible circuit board 201 are respectively fixed to the outer walls of multiple vertical strips 1. The flexible circuit board 201 is made of polyimide material with copper sheets wrapped inside. The bottom of the flexible circuit board 201 is fixed to the top of the first connector 202. The top of the flexible circuit board 201 is fixed to a second connector 203. Both the first connector 202 and the second connector 203 are made of copper material with polyimide material wrapped outside. A round block 205 is fixed to the outer wall of the first connector 202. A round opening 204 is processed on the front side of the second connector 203.

[0024] By having the first connector 202 at the bottom of the second flexible circuit board in the flexible circuit board structure 2 pass through the bent plate 5 on the outer wall of the second connector 203 at the top of the first flexible circuit board, and then the round block 204 behind the first connector 202 at the bottom of the second flexible circuit board is inserted into the round opening 204 on the front of the second connector 203 at the top of the first flexible circuit board, it is possible to prevent the two mating connectors from separating when the flexible circuit board is pulled, and at the same time reduce the gravity at the connection point, prevent the flexible circuit board from breaking over a long period of time, and ensure the normal use of the flexible circuit board.

[0025] The inner wall of the circular opening 204 is inserted into the outer wall of the circular block 205. Multiple first connecting strips 3 are fixedly connected to the outer wall of the first connector 202, and multiple second connecting strips 4 are fixedly connected to the outer wall of the second connector 203. Both the first connecting strips 3 and the second connecting strips 4 are made of copper. The outer walls of the first connector 202 and the second connector 203 are respectively fixedly connected to the ends of the outer walls of the vertical strips 1, which are made of polyimide. Bent plates 5 are fixedly connected to the upper left and right sides of the first connector 202.

[0026] Working principle:

[0027] Interlocking flexible circuit board connections:

[0028] The first connector 202 at the bottom of the second flexible circuit board passes through the bent plate 5 on the outer wall of the second connector 203 at the top of the first flexible circuit board. Then, the round block 204 behind the first connector 202 at the bottom of the second flexible circuit board is inserted into the round opening 204 on the front of the second connector 203 at the top of the first flexible circuit board. This prevents the two mating connectors from separating when the flexible circuit board is pulled. At this time, the first connecting strip 3 behind the first connector 202 is in contact with the second connecting strip 4 on the front of the second head 203. The first connecting strip 3 and the second connecting strip 4 can transmit electrical signals through their own copper material, thereby enabling the two connected flexible circuit boards to transmit electrical signals. Because the connector position is relatively rigid, the bent plate 5 presses on the connected second connector 203 to prevent the second connector 203 from tilting up.

[0029] Flexible circuit boards in use:

[0030] The flexible circuit board 201 is made of polyimide material that can withstand temperatures up to 200 degrees Celsius. It is also encased in copper sheets, which are fixed to the first connector 202 and the second connector 203 on the top and bottom sides. Both the first connector 202 and the second connector 203 are made of copper and work with the flexible circuit board 201 to conduct electrical signals. The outer walls of the first connector 202 and the second connector 203 are also covered with a polyimide material. The outer wall of the polyimide material covering layer has slots to expose the first connecting strip 3 and the second connecting strip 4 that connect to the first connector 202 and the second connector 203. Both the first connecting strip 3 and the second connecting strip 4 are made of copper and can transmit electrical signals to the first connector 202 and the second connector 203. The vertical strip 1, made of polyimide material, increases the connection points between the flexible circuit board 201, the first connector 202 and the second connector 203. When the box is pulled, the connectors break and detach from the flexible circuit board 201.
