Description

Technical Field

[0001] The utility model relates to a circuit board, in particular to an FPC which is convenient for plugging and unplugging. Background Art

[0002] Flexible printed circuit board, or FPC for short, is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness, good bending properties, and many advantages that rigid printed circuit boards do not have. FPC can be bent, wound, and folded freely, can be arranged arbitrarily according to the requirements of spatial layout, and can be moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] Conventional FPC connection methods mostly use a plug-in connector to snap-fit ​​the FPC terminal. However, due to the flexibility of the FPC, it is difficult to align the end of the FPC with the connector, which is very unfriendly to the use and installation of the FPC. Utility Model Content

[0004] Based on this, it is necessary to provide an FPC that is easy to plug and unplug in order to address the deficiencies in the prior art.

[0005] A pluggable FPC includes an FPC body, an FPC terminal and a connection seat. The FPC terminal is fixedly mounted at the end of the FPC body, and the FPC terminal can be plugged into the connection seat. The connection seat includes a shell, a plug board, a magnetic structure and a sliding handle. The shell is provided with a sliding cavity with an upper end and a side opening. The plug board is snap-fitted and mounted in the sliding cavity and can slide horizontally. The plug board is provided with a magnetic cavity, and a port slot is provided on one side. The magnetic structure is embedded in the magnetic cavity, and the sliding handle is integrally arranged at the upper end of the plug board and extends outside the upper end of the shell. The FPC terminal is made of permanent magnetic material, and can be plugged into the port slot of the plug board along one side of the shell. The magnetic structure is made of magnetic material, and can be magnetically aligned with the FPC terminal.

[0006] Furthermore, the magnetic attraction structure is an electromagnet structure, which includes an iron core and a coil wound outside the iron core. Electrical connection posts are also provided on both sides of the plug board, and the two ends of the coil are electrically connected to the two electrical connection posts respectively. An electrical contact is also provided on one side of the sliding cavity, and the electrical contact corresponds horizontally to the electrical connection post.

[0007] Furthermore, the connection base further comprises a limit block, and the FPC terminal is further provided with a limit groove. The limit block can be inserted into the sliding cavity from the upper end opening of the housing and engaged with the limit groove of the FPC terminal for limit position.

[0008] Furthermore, the upper surface of the sliding handle is provided with anti-slip grooves.

[0009] In summary, the beneficial effects of the FPC that is easy to plug and unplug of the utility model are: by designing a connecting seat with a sliding magnetic attraction structure and cooperating with the FPC terminal of the same magnetic material, the FPC is easier to align when plugged in, which greatly simplifies the difficulty of plugging in the FPC; the magnetic attraction structure in the connecting seat is designed as an electromagnet structure, so that it can change the direction of the magnetic pole when powered on, thereby repelling the FPC terminal, thereby simplifying the difficulty of removing the FPC; the limit block on the connecting seat can ensure that the plugging of the FPC terminal and the connecting seat is more firm and reliable, and the anti-slip pattern on the sliding handle makes it easier to push the plug board to slide when in use; the utility model is highly practical and has a strong promotion significance.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] like Figures 1 to 4 As shown, the utility model provides an FPC 100 that is easy to plug and unplug, which includes an FPC body 10, an FPC terminal 20 and a connecting seat 30. The FPC terminal 20 is fixedly mounted on the end of the FPC body 10, and the FPC terminal 20 can be plugged into the connecting seat 30.

[0016] The connection seat 30 includes a shell 31, a plug board 32, a magnetic structure 33 and a sliding handle 34. The shell 31 is provided with a sliding cavity 311 with an upper end and a side opening. The plug board 32 is snap-fitted and installed in the sliding cavity 311 and can slide horizontally. The plug board 32 is provided with a magnetic cavity (not shown) and a port slot 321 is provided on one side. The magnetic structure 33 is embedded in the magnetic cavity, and the sliding handle 34 is integrally provided at the upper end of the plug board 32 and extends outside the upper end of the shell 31. The FPC terminal 20 is made of permanent magnetic material, and the FPC terminal 20 can be plugged into the port slot 321 of the plug board 32 along one side of the shell 31. The magnetic structure 33 is made of magnetic material, and the magnetic structure 33 can be magnetically aligned with the FPC terminal 20.

[0017] When the FPC needs to be plugged in, firstly, the sliding handle 34 is applied to push the plug-in board 32 to slide so that one end of the plug-in board 32 can extend outside the housing 31. Then, the FPC terminal 20 and the plug-in board 32 are mutually attracted by magnetic attraction until the FPC terminal 20 is accurately plugged into the port slot 321 of the plug-in board 32. Then, the sliding handle 34 is applied with an opposite force to push the plug-in board 32 and the FPC terminal 20 connected to the plug-in board 32 back into the sliding cavity 311, and the quick plug-in of the FPC can be completed.

[0018] The magnetic attraction structure 33 is an electromagnet structure, which includes an iron core 331 and a coil 332 wound around the iron core 331. Electrical connection posts 322 are also provided on both sides of the plug board 32, and the two ends of the coil 332 are electrically connected to the two electrical connection posts 322 respectively. An electrical contact 312 is also provided on one side of the sliding cavity 311, and the electrical contact 312 corresponds horizontally to the electrical connection post 322. When the FPC needs to be removed, it is only necessary to apply force to the sliding handle 34 to push the plug board 32 to slide. When the electrical connection posts 322 on both sides of the plug board 32 contact the electrical contacts 312 on the inner side of the sliding cavity 311, the electromagnet is energized to generate a magnetic field. At this time, the electromagnet and the FPC are in a magnetic repulsive state, so that the FPC terminal 20 can be more easily detached from the port slot 321.

[0019] The connection seat 30 also includes a limit block 35, and the FPC terminal 20 is also provided with a limit groove 21. The limit block 35 can be inserted into the sliding cavity 311 from the upper end opening of the shell 31 and engage with the limit groove 21 of the FPC terminal 20. When the limit groove 21 of the FPC terminal 20 is in the sliding cavity 311, it is only necessary to insert the limit block 35 from the upper end of the shell 31 into the sliding cavity 311, and its bottom can be interlocked with the limit groove 21 to ensure that the FPC terminal 20 will not accidentally slip out of the sliding cavity 311. The upper surface of the sliding handle 34 is also provided with an anti-slip pattern 341, which can increase the friction coefficient of the upper surface of the sliding handle 34, making it easier to apply force to the sliding handle 34 during the process of plugging the FPC, thereby pushing the plug board 32 to slide.

[0020] In summary, the beneficial effects of the FPC100 that is easy to plug and unplug of the utility model are: by designing a connecting seat 30 with a sliding magnetic attraction structure 33 and cooperating with the FPC terminal 20 of the same magnetic material, the FPC is easier to align during plugging, which greatly simplifies the difficulty of plugging in the FPC; the magnetic attraction structure 33 in the connecting seat 30 is designed as an electromagnet structure, so that it can change the direction of the magnetic pole when powered on, thereby repelling the FPC terminal 20, thereby simplifying the difficulty of pulling out the FPC; the limit block 35 on the connecting seat 30 can ensure that the plugging of the FPC terminal 20 and the connecting seat 30 is more firm and reliable, and the anti-slip pattern 341 on the sliding handle 34 is more convenient for pushing the plug-in board 32 to slide during use; the utility model is highly practical and has a strong promotional significance.

[0021] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
