Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a rear-opening FPC connector. Background Art

[0002] An FPC connector is a flexible printed circuit board connector, typically used to connect two or more flexible printed circuit boards or to connect a flexible printed circuit board to a rigid circuit board.

[0003] my country's public patent, the utility model with application number CN202320939971.7, mentions a front-inserted and rear-lifted FPC connector that can prevent the back cover from falling off, specifically involving: "Plastic body and power terminals, the rear end of the plastic body is provided with a liftable back cover, the left and right sides of the back cover close to the plastic body are provided with a rotating shaft extending outward, the rear end of the supporting part is provided with a limiting part for limiting the rearward movement of the rotating shaft and protruding upward, the terminal avoidance groove is provided with a horizontally arranged support shaft, the pressing end includes a supporting part and a pressing part, and the supporting part is provided with a limiting groove for matching and inserting the support shaft and opening upward. A limiting part for limiting the rearward movement of the rotating shaft and protruding upward is provided on the supporting part, and a limiting groove for matching and inserting the support shaft and opening upward is provided on the supporting part. The support shaft is restricted in the limiting groove. Under the dual restrictions of the limiting part and the limiting groove, it is ensured that the back cover will not fall off, and the undesirable problem of falling off when the back cover is pressed down can be completely eliminated, so as to ensure that the yield rate can reach 100%".

[0004] In the front-insertion and rear-flipping FPC connector of the utility model, the rear cover is usually flipped to achieve connection with the flat FPC. However, in actual operation, we found that this method still has certain defects:

[0005] The back cover plays a prying role for the docking electrical terminals. When the back cover is flipped to be parallel to the outer shell, the connection to the flat FPC is stable. We found that when the working environment of the connector vibrates, since the back cover is not provided with a related limiting structure, when the back cover is vibrated, the back cover is very likely to loosen or rebound, thereby reducing the stabilizing effect of the back cover on the docking electrical terminals, and even causing the connection with the flat FPC to loosen, affecting the normal connection and use of the flat FPC and the connector.

The rear cover 5 is rotatably connected to the shell 2 through the rotating rod 503, which can ensure the connection stability of the rear cover 5; a limiting component is also provided on the top back of the mounting plate 1, and the limiting component includes a supporting plate 6 fixed on the mounting plate 1 and a limiting piece 7 integrally formed on the top of the front side of the supporting plate 6; an extrusion plate 9 is provided on the front side of the supporting plate 6, and a spring 8 is equidistantly fixed to the bottom of the extrusion plate 9, and the bottom of the spring 8 is fixed to the bottom of the supporting plate 6. The spring 8 can apply an upward thrust to the extrusion plate 9, thereby utilizing the extrusion plate 9 to push the entering rear cover 5, so that the rear cover 5 is more stably placed between the limiting piece 7 and the extrusion plate 9.

[0026] In this embodiment, the top of the limiting piece 7 is designed to be an inclined structure, and the top of the limiting piece 7 on a side close to the housing 2 is designed to be an arc structure.

[0027] Specifically, the limiting piece 7 is designed to be inclined, which can cooperate with the arc edge to facilitate the sliding of the rear flip cover 5, and the rear flip cover 5 can be smoothly restricted in position by the limiting piece 7.

[0028] In this embodiment, two vertical slide grooves 601 are provided on the front side of the support plate 6, and limiting grooves 6011 are provided on both sides of the inner wall of each slide groove 601, and sliders 901 are fixed on the back side of the extrusion plate 9 and at positions corresponding to each slide groove 601, and limiting blocks 9011 are fixed on the left and right sides of each slider 901; the back side of the extrusion plate 9 is attached to the front side of the support plate 6, the slider 901 is slidably connected in the slide groove 601, and the limiting block 9011 is slidably connected in the limiting groove 6011.

[0029] Specifically, a slide groove 601 and a limit groove 6011 are opened on the support plate 6, and a slider 901 and a limit block 9011 are set on the extrusion plate 9, which play a role in stabilizing the extrusion plate 9 and guiding the sliding trajectory. When the extrusion plate 9 has better stability, the rear cover 5 can have better stability on the extrusion plate 9 to avoid loosening of the rear cover 5.

[0030] In this embodiment, the power connection component 4 includes an upper clamping rod 401 and a lower clamping rod 402, which are fixed together by a connecting piece 403, the bottom of one end of the lower clamping rod 402 is fixed on the mounting plate 1, and one end of the upper clamping rod 401 passes through the through hole 501.

[0031] Specifically, when the upper clamp rod 401 approaches the lower clamp rod 402, the flat FPC can be clamped, so that the flat FPC is firmly fixed in the docking hole 3. The upper clamp rod 401 and the lower clamp rod 402 are connected by the connecting piece 403, and the connecting piece 403 can be used to provide good support and bending effects, thereby facilitating the movement of the upper clamp rod 401.

[0032] When using:

[0033] Insert the flat FPC into the housing 2 from the docking hole 3. At this time, the flat FPC is located between the upper clamping rod 401 and the lower clamping rod 402. Then flip the rear cover 5. The rear cover 5 rotates toward one side of the limit assembly. When the rear cover 5 rotates to the limit piece 7, since the limit piece 7 is designed as an inclined surface with an arc angle, the rear cover 5 can bend the support plate 6 with the pressing action of the staff, so that the rear cover 5 brings the bottom of the limit piece 7. When the rear cover 5 continues to rotate, it can The spring 8 can be compressed by pressing the extrusion plate 9. When the top of the rear flip cover 5 is in contact with the bottom of the limiting piece 7, the support plate 6 rebounds and remains vertical with the mounting plate 1, and finally the rear flip cover 5 is limited between the limiting piece 7 and the extrusion plate 9, which plays a role in limiting the rear flip cover 5. When subjected to vibration, the limiting piece 7 always provides the rear flip cover 5 with a force to prevent it from tilting up, and finally it can ensure that the rear flip cover 5 will not tilt up even if it is subjected to vibration, and ensure the stability of the rear flip cover 5 after flipping (such as Figure 5 as shown).

[0034] At the same time, when the rear flip cover 5 is rotated, the rotating rod 503 is used for rotation, thereby improving the smoothness of the rotation of the rear flip cover 5 and the stability of the rotating point, avoiding position deviation of the two ends of the rear flip cover 5 during rotation, and the tilting portion 5011 will rotate together with the rear flip cover 5, so that the tilting portion 5011 can be used to tilt one end of the upper clamping rod 401 upward, so that the upper clamping rod 401 can be tilted at one end and pressed at the other end by using the connecting piece 403, and finally the closing action of the upper clamping rod 401 to the lower clamping rod 402 is realized, and the flat FPC is clamped between the upper clamping rod 401 and the lower clamping rod 402, so as to realize the connection between the FPC connector and the flat FPC.
