Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a flip-top type flexible circuit board connector. Background Technology

[0002] Currently, circuit board connection devices are used in electronic devices such as computers, mobile phones, and tablets to achieve circuit connections between various electronic components or electronic devices. These circuit board connection devices generally use flexible circuit boards to be directly connected to an insulating base.

[0003] A search of publication number "CN205828797U" reveals "a flip-top connector, comprising an insulating body, a plurality of conductive terminals mounted on the insulating body, and a flip-top pivotally connected to the insulating body. The insulating body has a mating groove, and each conductive terminal has a contact portion protruding into the mating groove. The flip-top is located within the mating groove, and the insulating body also has a foolproof part located within the mating groove. This flip-top connector adds a foolproof part within the mating groove. In practical applications, the flexible circuit board has a corresponding structure that mates with the foolproof part. When the flexible circuit board is inserted into the mating groove, it effectively prevents the flexible circuit board from being inserted backwards, avoiding malfunction due to reverse insertion."

[0004] The aforementioned patent can improve the convenience and accuracy of circuit board insertion through a foolproof mechanism. However, in the aforementioned patent, the flexible circuit board is fixed entirely by a cover plate. This cover plate design may accidentally pop open or loosen in strong vibration or impact environments (such as drops from automotive electronics, industrial equipment, or portable devices), causing the flexible circuit board inside to detach from the insertion slot. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a flip-top type flexible circuit board connector, which can effectively solve the problem that the cover is easily popped open and loosened in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a flip-top type flexible circuit board connector, including a connector base. A cover plate is rotatably connected to the adjacent end of the connector base via a rotating shaft. A drive housing is fixedly connected to one end of the rotating shaft. A control groove is opened at one end of the drive housing. A third spring is fixedly connected to one end of the connector base. A force-bearing block is fixedly connected to one end of the third spring. A sliding sleeve is fixedly connected to one end of the force-bearing block. A fastening plate is fixedly connected to one end of the sliding sleeve. A control block is fixedly connected to one end of the fastening plate. The control block is movably engaged in the control groove.

[0008] Furthermore, a guide rod is fixedly connected to one end of the connecting seat, a placement groove is provided at the upper end of the guide rod, a first spring is fixedly connected to the lower inner wall of the placement groove, a snap-fit ​​block is fixedly connected to one end of the first spring, a snap-fit ​​groove is provided at the upper end of the sliding sleeve, and the snap-fit ​​block is movably snapped into the snap-fit ​​groove.

[0009] Furthermore, two second springs are fixedly connected to the upper end of the sliding sleeve, and a pressing plate is fixedly connected to the upper end of the two second springs. A disassembly rod is fixedly connected to the lower end of the pressing plate.

[0010] Furthermore, the upper end of the sliding sleeve is fixedly connected to two vertical rods, and the upper end of the pressing plate is provided with two limiting holes, and the pressing plate is slidably connected to the circumferential surface of the two vertical rods through the two limiting holes respectively.

[0011] Furthermore, anti-detachment blocks are fixedly connected to the upper ends of both vertical rods, and the diameter of the two anti-detachment blocks is larger than the diameter of the two vertical rods.

[0012] Furthermore, a first telescopic rod is fixedly connected to the lower inner wall of the placement groove, and the first spring is sleeved on the circumferential surface of the first telescopic rod.

[0014] Furthermore, the connector is provided with a conductive terminal, one end of which is fixedly connected to multiple conductive ports, and one end of the cover plate is provided with multiple anti-collision grooves.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. The circuit board can be connected through the conductive terminals. Then, the cover plate is rotated to cover the connector, fixing the circuit board and conductive terminals. After the cover plate and connector are completely covered, the elastic retraction of the third spring pulls the force block, which simultaneously drives the sliding sleeve and fastening plate to move, so that the control block is movable and locked in the control groove opened at one end of the drive shell, preventing the drive shell from rotating, thereby preventing the shaft and cover plate from rotating, preventing the cover plate from rotating accidentally, and improving the tightness of the installation of the circuit board inside.

[0018] Second, when the sliding sleeve moves, it can slide on the outer surface of the guide rod, which improves the horizontal movement stability of the sliding sleeve. After the sliding sleeve moves to the appropriate position, the first spring fixed to the inner wall of the placement groove expands elastically to insert the snap-fit ​​block into the snap-fit ​​groove, which facilitates the fixation of the position of the sliding sleeve, thereby fixing the position of the fastening plate and further improving the stability of the device.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figures 1-7 A flip-top type flexible circuit board connector includes a connector 1. A cover plate 2 is rotatably connected to the adjacent end of the connector 1 via a rotating shaft. A drive housing 19 is fixedly connected to one end of the rotating shaft. A control groove is opened at one end of the drive housing 19. A third spring 22 is fixedly connected to one end of the connector 1. A force-bearing block 21 is fixedly connected to one end of the third spring 22. A sliding sleeve 4 is fixedly connected to one end of the force-bearing block 21. A fastening plate 3 is fixedly connected to one end of the sliding sleeve 4. A control block 24 is fixedly connected to one end of the fastening plate 3. The control block 24 is movably engaged in the control groove.

[0031] In a specific embodiment of this utility model, the circuit board can be connected through conductive terminals. Then, the cover plate 2 is rotated to cover the connecting seat 1, fixing the circuit board and conductive terminals. After the cover plate 2 and the connecting seat 1 are completely covered, the force block 21 is pulled by the elastic retraction of the third spring 22, which simultaneously drives the sliding sleeve 4 and the fastening plate 3 to be pulled, so that the control block 24 is movably engaged in the control groove opened at one end of the drive shell 19, preventing the drive shell 19 from rotating, thereby preventing the rotating shaft and the cover plate 2 from rotating, preventing the cover plate 2 from rotating accidentally, and improving the tightness of the installation of the circuit board inside.

[0032] Please refer to the details. Figures 1-7 One end of the connecting seat 1 is fixedly connected to a guide rod 5. The upper end of the guide rod 5 is provided with a placement groove 8. The lower inner wall of the placement groove 8 is fixedly connected to a first spring 9. One end of the first spring 9 is fixedly connected to a snap-fit ​​block 12. The upper end of the sliding sleeve 4 is provided with a snap-fit ​​groove 11. The snap-fit ​​block 12 is movably snapped into the snap-fit ​​groove 11.

[0033] In this embodiment: when the sliding sleeve 4 moves, it can slide on the outer surface of the guide rod 5 to improve the horizontal movement stability of the sliding sleeve 4. After the sliding sleeve 4 moves to a suitable position, the first spring 9, which is fixedly connected to the lower inner wall of the placement groove 8, elastically expands to insert the snap-fit ​​block 12 into the snap-fit ​​groove 11, which facilitates fixing the position of the sliding sleeve 4 and thus fixing the position of the fastening plate 3, further improving the stability of the device.

[0034] Please refer to the details. Figures 1-7 Two second springs 18 are fixedly connected to the upper end of the sliding sleeve 4. A pressing plate 15 is fixedly connected to the upper end of the two second springs 18. A disassembly rod is fixedly connected to the lower end of the pressing plate 15. Two vertical rods 16 are fixedly connected to the upper end of the sliding sleeve 4. Two limiting holes are opened at the upper end of the pressing plate 15, and the pressing plate 15 is slidably connected to the circumferential surface of the two vertical rods 16 through the two limiting holes respectively.

[0035] In this embodiment: when the sliding sleeve 4 needs to be moved again, the pressing of the pressing plate 15 causes the disassembly rod at its lower end to push the snap block 12 away from the snap groove 11, making it easier to move the sliding sleeve 4 again. When the pressing plate 15 moves, it can slide on the circumferential surface of the vertical rod 16 through the limiting hole, thereby improving the vertical movement stability of the pressing plate 15.

[0036] Please refer to the details. Figures 1-7 The upper ends of the two vertical rods 16 are fixedly connected with anti-detachment blocks 17. The diameter of the two anti-detachment blocks 17 is larger than the diameter of the two vertical rods 16. The lower inner wall of the placement groove 8 is fixedly connected with a first telescopic rod 10. The first spring 9 is sleeved on the circumferential surface of the first telescopic rod 10.

[0037] In this embodiment: the anti-detachment block 17 can prevent the pressing plate 15 from being damaged due to excessive sliding, and the first telescopic rod 10 can prevent the first spring 9 from being damaged due to bending deformation.

[0038] Please refer to the details. Figures 1-7 A limiting groove 13 is provided on the inner circumference of the placement groove 8. A limiting block 14 is fixedly connected to the circumferential surface of the snap-fit ​​block 12. The limiting block 14 is slidably connected in the limiting groove 13. A conductive terminal is provided in the connecting seat 1. Multiple conductive ports 6 are fixedly connected to one end of the conductive terminal. Multiple anti-collision grooves 7 are provided at one end of the cover plate 2.

[0039] In this embodiment: when the snap-fit ​​block 12 moves, it can drive the limiting block 14 to move within the limiting groove 13, thereby improving the vertical movement stability of the snap-fit ​​block 12. When the pressing plate 15 moves, it can slide on the circumferential surface of the vertical rod 16 through the limiting hole, thereby improving the vertical movement stability of the pressing plate 15. The conductive port 6 facilitates the connection between the internal conductive terminals of the connector 1 and the external power cord. The anti-collision groove 7 prevents the cover plate 2 from colliding with the conductive port 6 when it is closed.

[0040] Preferably, a limiting plate 20 is fixedly connected to one end of the guide rod 5. The limiting plate 20 can prevent the sliding sleeve 4 from being damaged due to excessive sliding.

[0041] Preferably, one end of the connecting seat 1 is fixedly connected to a telescopic tube 23, and the third spring 22 is sleeved on the circumferential surface of the telescopic tube 23. The telescopic tube 23 can prevent the third spring 22 from being damaged due to bending deformation.

[0042] Working principle: The circuit board can be connected through the conductive terminals. Then, the cover plate 2 is rotated to cover the connecting seat 1, fixing the circuit board and conductive terminals. After the cover plate 2 and the connecting seat 1 are completely covered, the elastic retraction of the third spring 22 pulls the force block 21, which simultaneously drives the sliding sleeve 4 and the fastening plate 3 to move, so that the control block 24 is movably engaged in the control groove opened at one end of the drive shell 19, preventing the drive shell 19 from rotating, thereby preventing the rotating shaft and the cover plate 2 from rotating, preventing the cover plate 2 from rotating accidentally, and improving the tightness of the installation of the circuit board inside.
