Cap-falling prevention FPC connector

Abstract

The present application relates to the technical field of FPC connector, especially to a FPC connector capable of preventing cover from falling off. The FPC connector comprises a connecting shell and a cover body rotatably connected to the connecting shell through a connecting shaft. Terminals are arranged on the connecting shell and below the cover body. The FPC inserted into the connecting shell drives the cover body to turn down by itself, and the FPC is clamped and locked on the connecting shell. Thus, the traditional cover body is clamped on the connecting shell by pressing, so that the cover body locked on the connecting shell is prevented from opening by itself due to external force, and the problem that the FPC is damaged due to excessive pressure when the cover body turns down is avoided. In addition, the oxide layer on the terminals can be scraped when the FPC is inserted into the connecting shell, so that the thick oxide layer on the surface of the terminals caused by the contact with air does not affect the connection with the FPC.

Description

Technical Field

[0001] This invention relates to the field of FPC connector technology, and in particular to an FPC connector with an anti-cap-fall-off feature. Background Technology

[0002] An FPC connector is an interface device used to connect flexible printed circuit boards (FPCs) to other electronic components or circuits. Specifically designed for flexible circuit boards, FPC connectors enable electrical connections and signal transmission while maintaining the flexibility and bendability of the circuitry.

[0003] Currently, commonly used FPC connectors have a rotating cover plate. When the FPC is connected to the FPC connector, the cover plate needs to be rotated, and the cover plate is pressed and locked inside the connector by the protrusions on the cover plate. This locks the FPC on the FPC connector in position. Although this can lock the FPC on the FPC connector, the cover plate locked on the FPC connector is easy to open under force, and the pressure of the cover plate on the FPC connector is not easy to control, which can easily damage the FPC due to excessive pressure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] An anti-drop FPC connector includes a connecting housing and a cover plate body rotatably connected to the connecting housing via a connecting shaft. The connecting housing is provided with terminals located below the cover plate body. The terminals are used to connect to an FPC. The connecting housing is provided with a cover plate anti-drop component. The FPC inserted into the connecting housing moves the cover plate body downward through the cover plate anti-drop component and automatically locks the FPC.

[0006] As an improvement to the above technical solution, the cover plate anti-drop assembly includes multiple gears mounted on a connecting shaft and multiple sockets opened on a connecting housing. The gears are located inside the connecting housing, and the sockets are located above the terminals. The multiple sockets communicate with the multiple gears respectively. A plug is inserted into the socket, and a toothed groove is opened on the upper end face of the plug. The multiple gears mesh with the toothed grooves on the multiple plugs respectively. A push plate is connected to one side of the multiple plugs. A pressing spring is provided at the bottom of the inner side of the socket. One end of the pressing spring is connected to the plug inserted into the socket. A scraper is provided on the lower end face of the push plate, and the scraper engages with the terminals on the connecting housing.

[0007] As an improvement to the above technical solution, grooves are provided at both ends of the cover plate body, a first positioning rod is inserted into the groove, a return spring is provided at the bottom of the inner side of the groove, one end of the return spring is connected to the first positioning rod in the groove, and a chamfer is provided at the end of the first positioning rod away from the groove.

[0008] As an improvement to the above technical solution, two first positioning holes are provided on the connecting housing, and the two first positioning holes correspond to the positions of the two first positioning rods respectively. A top block is provided in the first positioning hole.

[0009] As an improvement to the above technical solution, a pressing rod is provided on the top block, the end of the pressing rod away from the top block passes through the connecting housing, and a limiting ring is provided on the pressing rod, the limiting ring being located on one side of the connecting housing.

[0010] As an improvement to the above technical solution, the upper end face of the connecting housing is provided with a folding storage and dust removal assembly. The folding storage and dust removal assembly includes a storage groove opened on the upper end face of the connecting housing and a sealing plate rotatably connected in the storage groove. A first flip plate is rotatably arranged at both ends of the inner side of the storage groove. A second flip plate is rotatably connected to one end of the first flip plate, and a sliding connecting plate is rotatably connected to one end of the second flip plate.

[0011] As an improvement to the above technical solution, a sliding rod is provided between the two sliding connecting plates, and sliders are provided at both ends of the sliding rod. Sliding grooves are provided on both sliding connecting plates, and the sliders at both ends of the sliding rod are slidably connected in the sliding grooves of the two sliding connecting plates. A movable plate is sleeved on the sliding rod, and a dust cleaning brush is provided on the movable plate.

[0012] As an improvement to the above technical solution, locking components are provided at both ends of the connecting housing. The locking components are used to lock the position of the sealing plate inside the storage groove. The locking components include second positioning holes opened at both ends of the sealing plate and two receiving grooves opened inside the connecting housing. The two receiving grooves correspond to the positions of the two second positioning holes on the sealing plate, respectively.

[0013] As an improvement to the above technical solution, a fixing block is provided in the receiving groove. A second positioning rod is provided at one end of the fixing block. One end of the second positioning rod passes through the connecting shell. A helical spring is sleeved on the second positioning rod. One end of the helical spring is connected to the fixing block. Two sinking grooves and two arc-shaped grooves are opened at the other end of the fixing block. The two sinking grooves and the two arc-shaped grooves are arranged in a cross shape. The cross-section of the sinking groove is an isosceles trapezoid, and the opening depth of the sinking groove is greater than the opening depth of the arc-shaped groove.

[0014] As an improvement to the above technical solution, two limiting grooves are formed on the inner wall of the receiving groove, and two limiting guide blocks are provided on the fixing block. The two limiting guide blocks are slidably connected in the two limiting grooves on the inner wall of the two receiving grooves respectively. A rotating rod is provided in the receiving groove. The rotating rod is located on one side of the fixing block. Two top plates are provided on the rotating rod. The two top plates are abutted against one end of the fixing block. The two corners of the top plates abutting against one end of the fixing block are rounded. A fixing ring is provided on the rotating rod. A fixing groove is formed in the connecting housing. The fixing ring on the rotating rod is rotatably connected to the fixing groove in the connecting housing. A rotating block is provided at the end of the rotating rod that passes through the connecting housing.

[0015] The beneficial effects of this invention are:

[0016] 1. The cover plate anti-drop component allows the FPC inserted into the connecting housing to automatically flip the cover plate downwards, clamping and locking the FPC onto the connecting housing. This replaces the traditional method of pressing the cover plate onto the connecting housing, thereby reducing the risk of the cover plate opening due to external force and preventing damage to the FPC caused by excessive downward pressure from the cover plate. In addition, the oxide layer on the terminals can be scraped off while the FPC is inserted into the connecting housing, which can prevent the oxide layer on the terminal surface from becoming too thick due to contact with air, thus affecting the connection with the FPC.

[0017] 2. The push plate, insert block, tooth groove and gear are set to make the FPC inserted on the connecting housing drive the cover plate body to flip down by itself, thereby clamping the FPC on the connecting housing and locking the position of the FPC.

[0018] 3. By setting the groove, return spring, chamfer and first positioning hole, the first positioning rod on the cover plate body can be flipped to the first positioning hole on the connecting housing to lock the position of the cover plate body. This not only restricts the locking position of the cover plate body, but also makes the connection stability of the cover plate body locked on the connecting housing high and it is not easy for the cover plate body to be dislodged from the connecting housing due to force.

[0019] 4. The first positioning rod inserted into the first positioning hole can be pushed out by the top block and the pressing rod, thus unlocking the cover plate body locked on the connecting housing. The unlocked cover plate body can be opened by itself by the setting of the fixing spring, gear, insert block and tooth groove and return to the initial open state.

[0020] 5. The scraper on the push plate scrapes off the oxide layer on the surface of the terminals on the connecting housing during the push plate's movement. This prevents the connection between the FPC and the terminals from being affected by a thick oxide layer on the terminal surface. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Please see Figure 1 The present invention provides a solution: an FPC connector with an anti-drop cover, comprising a connecting housing 1 and a cover plate body 3 rotatably connected to the connecting housing 1 via a connecting shaft 4. The connecting housing 1 is provided with a terminal 2 located below the cover plate body 3. The terminal 2 is used to connect to an FPC. The connecting housing 1 is provided with a cover plate anti-drop component 5. The FPC inserted into the connecting housing 1 moves the cover plate body 3 downward through the cover plate anti-drop component 5 and automatically locks the FPC.

[0037] Please see Figures 2-7In this embodiment, the cover plate anti-drop component 5 includes multiple gears 51 disposed on the connecting shaft 4 and multiple sockets 52 opened on the connecting housing 1. The gears 51 are disposed inside the connecting housing 1, and the sockets 52 are located above the terminals 2. The multiple sockets 52 are respectively connected to the multiple gears 51. A plug block 53 is inserted into the socket 52. The upper end face of the plug block 53 is provided with a tooth groove 54. The multiple gears 51 respectively mesh with the tooth groove 54 on the multiple plug blocks 53. A push plate 55 is connected to one side of the multiple plug blocks 53. A pressing spring 514 is disposed at the bottom end of the inner side of the socket 52. One end of the pressing spring 514 is connected to the plug block 53 inserted into the socket 52. A scraper 515 is disposed at the lower end face of the push plate 55. The scraper 515 is engaged with the terminals 2 on the connecting housing 1. The cover plate body 3 has grooves 56 at both ends, and a first positioning rod 57 is inserted into the groove 56. A return spring 58 is provided at the bottom of the inner side of the groove 56. One end of the return spring 58 is connected to the first positioning rod 57 in the groove 56. The end of the first positioning rod 57 away from the groove 56 has a chamfer 59. The connecting housing 1 has two first positioning holes 510, which correspond to the positions of the two first positioning rods 57 respectively. A top block 511 is provided in the first positioning hole 510. A pressing rod 512 is provided on the top block 511. The end of the pressing rod 512 away from the top block 511 passes through the connecting housing 1. A limit ring 513 is provided on the pressing rod 512, and the limit ring 513 is located on one side of the connecting housing 1.

[0038] In use, place one end of the FPC on the upper surface of terminal 2, and then push the FPC so that its movement abuts against the push plate 55. The push plate 55, under force, drives the scraper 515 and the insert block 53 to move towards the bottom inner side of the socket 52. The movement of the scraper 515 scrapes off the oxide layer on the surface of terminal 2, and the movement of the insert block 53 compresses the pressing spring 514 inside the socket 52. The pressing spring 514 is compressed under force. During the movement of the insert block 53, the connecting shaft 4, which is equipped with a gear 51, is rotated through the toothed groove 54. The connecting shaft 4 drives the cover plate body 3 to flip towards the FPC. When the first positioning rod 57 on the cover plate body 3 flips onto the connecting housing 1, the chamfer 59 on the first positioning rod 57 abuts against the connecting housing 1. At this time, the first positioning rod 57 is forcefully contracted towards the inner side of the groove 56, and When the return spring 58 inside the groove 56 is pressed, and the first positioning rod 57 rotates to correspond to the position of the first positioning hole 510 on the connecting housing 1, one end of the first positioning rod 57 is inserted into the first positioning hole 510 on the connecting housing 1. At this time, the pushing of the FPC stops, and the cover plate body 3 locks the position of the FPC placed on the connecting housing 1. When it is necessary to separate the FPC from the connecting housing 1, press the pressing rod 512. The pressing rod 512 pushes out the first positioning rod 57 inserted in the first positioning hole 510 through the top block 511. At this time, the pressing spring 514 in the insertion port 52 pushes the FPC placed on the connecting housing 1 outward through the push plate 55, and the cover plate body 3 flips upward. When the cover plate body 3 and the FPC are separated, the FPC placed on the connecting housing 1 can be removed.

[0039] The cover plate anti-drop component 5 causes the FPC inserted into the connecting housing 1 to cause the cover plate body 3 to flip downwards on its own, clamping and locking the FPC onto the connecting housing 1. This replaces the traditional method of pressing the cover plate body 3 onto the connecting housing 1, reducing the risk of the cover plate body 3 opening on its own due to external force, and avoiding damage to the FPC caused by excessive downward pressure from the cover plate body 3. In addition, while the FPC is inserted into the connecting housing 1, the oxide layer on the terminal 2 can be scraped off, which can prevent the oxide layer on the surface of the terminal 2 from being too thick due to contact with air, thus affecting the connection with the FPC.

[0040] Please see Figure 8In this embodiment, a folding and dust-removing assembly is provided on the upper surface of the connecting housing 1. The folding and dust-removing assembly includes a storage groove 61 formed on the upper surface of the connecting housing 1 and a sealing plate 62 rotatably connected in the storage groove 61. A first flip plate 63 is rotatably provided at both ends of the inner side of the storage groove 61. A second flip plate 64 is rotatably connected to one end of the first flip plate 63, and a sliding connecting plate 65 is rotatably connected to one end of the second flip plate 64. A sliding rod 67 is provided between the two sliding connecting plates 65. A slider 68 is provided at both ends of the sliding rod 67. A groove 66 is formed on both sliding connecting plates 65. The sliders 68 at both ends of the sliding rod 67 are slidably connected in the grooves 66 on the two sliding connecting plates 65. A movable plate 69 is sleeved on the sliding rod 67, and a dust cleaning brush 610 is provided on the movable plate 69.

[0041] When in use, if it is necessary to clean the dust at terminal 2, open the sealing plate 62, and then flip the first flip plate 63, the second flip plate 64, and the sliding connecting plate 65 in sequence so that the dust cleaning brush 610 between the two sliding connecting plates 65 is above terminal 2. Then move it back and forth along the slide groove 66 and left and right along the slide rod 67 to clean the dust at terminal 2. When the dust at terminal 2 is cleaned, fold the dust cleaning brush 610 in the reverse order of the above steps and place it in the storage slot 61. Then cover the storage slot 61 with the sealing plate 62.

[0042] The foldable dust removal component allows for quick cleaning of dust at terminal 2, improving device maintenance efficiency. Furthermore, the first flip plate 63, the second flip plate 64, and the sliding connecting plate 65 connected to the dust removal brush 610 can be flipped and folded, allowing the dust removal brush 610 to be folded and stored, thus reducing the space occupied by the dust removal brush 610.

[0043] Please see Figures 9-12In this embodiment, locking components 7 are provided at both ends of the connecting housing 1. The locking components 7 are used to lock the position of the sealing plate 62 inside the receiving groove 61. The locking components 7 include second positioning holes 71 opened at both ends of the sealing plate 62 and two receiving grooves 72 opened inside the connecting housing 1. The two receiving grooves 72 correspond to the positions of the two second positioning holes 71 on the sealing plate 62, respectively. A fixing block 73 is provided in the receiving groove 72. A second positioning rod 74 is provided at one end of the fixing block 73. One end of the second positioning rod 74 passes through the connecting housing 1. A helical spring 75 is sleeved on the second positioning rod 74. One end of the helical spring 75 is connected to the fixing block 73. The other end of the fixing block 73 has two recessed grooves 76 and two arc-shaped grooves 77. The two recessed grooves 76 and the two arc-shaped grooves 77 are arranged in a cross shape. The cross-section of the recessed groove 76 is an isosceles trapezoid, and the opening depth of the recessed groove 76 is greater than the opening depth of the arc-shaped groove 77. Two limiting grooves 79 are formed on the inner wall of the receiving groove 72. Two limiting guide blocks 78 are provided on the fixing block 73. The two limiting guide blocks 78 are slidably connected in the two limiting grooves 79 on the inner wall of the two receiving grooves 72. A rotating rod 710 is provided in the receiving groove 72. The rotating rod 710 is located on one side of the fixing block 73. Two top plates 713 are provided on the rotating rod 710. The two top plates 713 are abutted on one end of the fixing block 73. The two corners of the top plates 713 abutting one end of the fixing block 73 are rounded. A fixing ring 711 is provided on the rotating rod 710. A fixing groove 712 is formed in the connecting housing 1. The fixing ring 711 on the rotating rod 710 is rotatably connected in the fixing groove 712 in the connecting housing 1. A rotating block 714 is provided at one end of the rotating rod 710 that passes through the connecting housing 1.

[0044] In use, when the sealing plate 62 is placed inside the storage groove 61, the rotating block 714 drives the rotating rod 710 and the top plate 713 to rotate. When the top plate 713 rotates to the arc groove 77 on the fixed block 73, the top plate 713 pushes the second positioning rod 74 on the fixed block 73 to move towards the sealing plate 62, so that one end of the second positioning rod 74 is inserted into the second positioning hole 71 on the sealing plate 62. At this time, the sealing plate 62 is locked in the storage groove 61. If it is necessary to open the sealing plate 62, the rotating block 714 continues to rotate the top plate 713 on the rotating rod 710. When the top plate 713 rotates from the arc groove 77 on the fixed block 73 to the recessed groove 76 on the fixed block 73, the coil spring 75 pushes the second positioning rod 74 to move towards the rotating block 714 through the fixed block 73. When the second positioning rod 74 moves out of the second positioning hole 71 on the sealing plate 62, the sealing plate 62 can be flipped open normally.

[0045] The locking component 7 allows the sealing plate 62 to be locked and unlocked by rotating the rotating block 714, making the locking and unlocking process of the sealing plate 62 simple and convenient.

[0046] Working principle of this invention:

[0047] Place one end of the FPC on the upper surface of terminal 2, and then push the FPC so that its movement abuts against the push plate 55. The push plate 55, under force, drives the insert block 53 to move towards the bottom of the inlet 52. The movement of the insert block 53 compresses the pressing spring 514 inside the inlet 52. The pressing spring 514 is compressed by force. During the movement of the insert block 53, the connecting shaft 4, which is equipped with gear 51, is rotated through the toothed groove 54. The connecting shaft 4 drives the cover plate body 3 to flip towards the FPC. When the first positioning rod 57 on the cover plate body 3 flips onto the connecting housing 1, the chamfer 59 on the first positioning rod 57 abuts against the connecting housing 1. At this time, the first positioning rod 57 is forcefully contracted towards the inside of the groove 56, and the return spring inside the groove 56 is also retracted. When the first positioning rod 57 rotates to correspond with the first positioning hole 510 on the connecting housing 1, one end of the first positioning rod 57 is inserted into the first positioning hole 510 on the connecting housing 1. At this time, the pushing of the FPC stops, and the cover body 3 locks the position of the FPC placed on the connecting housing 1. When it is necessary to separate the FPC from the connecting housing 1, press the pressing rod 512. The pressing rod 512 pushes out the first positioning rod 57 inserted into the first positioning hole 510 through the top block 511. At this time, the pressing spring 514 in the insertion port 52 pushes the FPC placed on the connecting housing 1 outward through the push plate 55, and the cover body 3 flips upward. When the cover body 3 separates from the FPC, the FPC placed on the connecting housing 1 is... The FPC can be removed. If it is necessary to clean the dust at terminal 2, open the sealing plate 62, and then flip the first flip plate 63, the second flip plate 64, and the sliding connecting plate 65 in sequence so that the dust cleaning brush 610 between the two sliding connecting plates 65 is above terminal 2. Then move it back and forth along the slide groove 66 and left and right along the slide rod 67 to clean the dust at terminal 2. When the dust at terminal 2 is cleaned, fold the dust cleaning brush 610 in the reverse order and place it in the storage groove 61. Then cover the storage groove 61 with the sealing plate 62. When the sealing plate 62 is covered in the storage groove 61, the rotating rod 710 and the top plate 713 will rotate through the rotating block 714. When the top plate 713 rotates... When the top plate 713 moves to the arc groove 77 on the fixing block 73, it pushes the second positioning rod 74 on the fixing block 73 toward the sealing plate 62, so that one end of the second positioning rod 74 is inserted into the second positioning hole 71 on the sealing plate 62. At this time, the sealing plate 62 is locked in the storage groove 61. If it is necessary to open the sealing plate 62, the top plate 713 on the rotating rod 710 is rotated by the rotating block 714. When the top plate 713 moves from the arc groove 77 on the fixing block 73 to the recessed groove 76 on the fixing block 73, the coil spring 75 pushes the second positioning rod 74 toward the rotating block 714 through the fixing block 73. When the second positioning rod 74 moves out of the second positioning hole 71 on the sealing plate 62, the sealing plate 62 can be flipped open normally.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
