Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of circuit board, concretely is a plug -in flexible circuit board. BACKGROUND

[0002] Flexible circuit board is widely used in various electronic products because of its bending property, and with the development of electronic products towards high density and miniaturization, flexible circuit board also gradually develops towards light, thin and flexible. In the assembly process of the flexible circuit board, the flexible circuit board is generally plugged into the connecting port of the external circuit accessory.

[0003] For example, the existing publication number CN216217764U specifically discloses a plug-in flexible circuit board, which is plugged into the connecting port of the external circuit accessory through the connector provided at the end of the flexible circuit board. The plug-in process is more smooth, and if there is a problem that cannot be plugged in, it is also easy to feel, and there will be no hard insertion that causes the circuit board to bend. In addition, in the plug-in process, the worker's hand is holding the circuit board by pressing the board, so that the flexible circuit board will not bend in the case of large plug-in resistance. In addition, when the plug-in is completed, the plug is located in the socket of the connecting port of the external circuit accessory, so that the plug-in is more firm and stable.

[0004] However, in the implementation of the related technology, it is found that the above-mentioned has the following problems: when the connector of the above-mentioned flexible circuit board is plugged into the connecting port of the external circuit accessory, the connector is completely located in the connecting port at this time. When it is necessary to pull out the connector from the connecting port, the above-mentioned way is that the worker holds the connector by pressing the board with his hand and pulling it out. However, this way is to directly pull the connector out by dragging the circuit board. The force pulled out by the worker's hand is directly applied to the circuit board, which will cause a large traction force between the end of the flexible circuit board and the connector. Since the flexible circuit board itself has the characteristics of flexibility and thinness, it will easily cause the connection between the end of the flexible circuit board and the connector to break, or even directly separate the end of the flexible circuit board from the connector and cannot be used. Therefore, the above-mentioned flexible circuit board is not convenient for pulling out the connector from the connecting port of the external circuit accessory, and directly pulling out the connector by the circuit board will easily cause the connection between the end of the flexible circuit board and the connector to break and cannot be used.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0027] Embodiment: as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 And Figure 8 Indicated, the utility model a plug -in flexible circuit board, including joint 1, flexible circuit board body 2 and connecting port 3, joint 1 sets up in the end of flexible circuit board body 2, and joint 1 is inserted in connecting port 3, and the recess 4 is set up in the both sides of joint 1, and the hinged plate 5 is hinged on the inner wall of two recesses 4 respectively, and the connecting plate 6 is fixedly connected to one end of two hinged plates 5 respectively, and the pressing assembly 7 for pressing connecting plate 6 is arranged on one end of two connecting plates 6 respectively, and the mounting groove 9 is set up on the bottom of two recesses 4 respectively, and the spring 10 is fixedly connected in two mounting grooves 9 respectively, and one end of two springs 10 is fixedly connected on two connecting plates 6 respectively, and the card mouth 11 is penetrated and set up on the both sides of connecting port 3 respectively, and the card piece 8 for being clamped into the card mouth 11 is arranged on two connecting plates 6 respectively.

[0028] In use, when the connector 1 needs to be inserted into the connection port 3, the worker first presses the two connecting plates 6 to the middle through the two pressing assemblies 7 respectively, and then inserts the connector 1 into the connection port 3 completely, at this time, the two pressing assemblies 7 are loosened, and the clamping piece 8 is automatically clamped into the corresponding clamping opening 11 under the elastic force of the spring 10, which can improve the firmness of the connector 1 inserted into the connection port 3; when the connector 1 needs to be pulled out of the connection port 3, the worker first presses the two connecting plates 6 to the middle through the two pressing assemblies 7 respectively, so that the two clamping pieces 8 are moved out of the two clamping openings 11, and then the worker directly pulls out the connector 1 from the connection port 3 by pressing the two pressing assemblies 7 with his hands, and finally loosens the two pressing assemblies 7, so that the two connecting plates 6 are bounced to the initial position under the elastic force of the two springs 10. Therefore, the worker only needs to press the two pressing assemblies 7 with his hands to conveniently insert the connector 1 into the connection port 3 or pull the connector 1 out of the connection port 3. Since the two pressing assemblies 7 are located on one side of the connector 1, when the connector 1 is completely inserted into the connection port 3, the two pressing assemblies 7 are exposed outside the connection port 3, so the worker can directly and conveniently press the two pressing assemblies 7 with his hands to pull out the connector 1 from the connection port 3, thereby preventing the connector 1 and the end of the flexible circuit board body 2 from generating a pulling force during the pulling-out process, and further avoiding the situation that the connection between the end of the flexible circuit board body 2 and the connector 1 is broken or even directly disconnected and cannot be used, which greatly facilitates the process of pulling the connector 1 out of the connection port 3 of the external circuit accessory, and solves the defects in the prior art that it is inconvenient to pull the connector out of the connection port of the external circuit accessory, and directly pulling the connector out of the connection port through the circuit board is easy to cause the connection between the end of the flexible circuit board and the connector to be broken and cannot be used.

Through the arc-shaped structure of the anti-breaking plate 72, when a large bending force is generated between the end of the flexible circuit board body 2 and the connector 1, the anti-breaking plate 72 can play a blocking role on the flexible circuit board body 2, avoiding the over-bending of the flexible circuit board body 2 and causing the breaking of the connection between the end of the flexible circuit board body 2 and the connector 1.

[0030] The card piece 8 comprises a fixed block 81 fixedly connected to the connecting plate 6, the fixed block 81 is provided with a card block 82, the card block 82 is an arc structure, the card block 82 is rotatably connected to the fixed block 81 through a rotating shaft, the fixed block 81 is fixedly connected with a first magnet piece 83, the card block 82 is fixedly connected with an iron piece 84, and the iron piece 84 is matched with the first magnet piece 83.

[0031] The second magnet piece 12 is fixedly connected to the both sides of the connecting port 3, and the second magnet piece 12 is matched with the iron piece 84.

[0032] When the connector 1 is completely inserted into the connecting port 3, the fixed block 81 is clamped into the card hole 11, and the card block 82 is extended to the outside of the connecting port 3, at this time, the iron piece 84 is adsorbed to the second magnet piece 12 by rotating the card block 82, so that the fixed block 81 is limited, and the stability of the connector 1 inserted into the connecting port 3 can be improved; when the connector 1 needs to be pulled out of the connecting port 3, the card block 82 needs to be rotated back to the original position first, so that the iron piece 84 is adsorbed to the first magnet piece 83, then the fixed block 81 and the card block 82 are moved out of the card hole 11 by pressing the pressing plate 71, and the connector 1 is pulled out of the connecting port 3.
