Description

Technical Field

[0001] This utility model belongs to the field of FPC connector technology, and in particular relates to a rear-hinged FPC connector. Background Technology

[0002] FFC / FPC flexible connectors are a new type of data cable made of PET insulating material and ultra-thin tin-plated flat copper wire pressed together by high-tech automated equipment. They have advantages such as flexibility, easy bending and folding, thinness, small size, simple connection, convenient disassembly, and easy solution of electromagnetic shielding (EMI).

[0003] Existing rear-hinged FPC connectors typically use a rear cover that rotates to a vertical position to clamp the FPC. However, in vibrating operating environments, the locking mechanism of the rear cover is prone to slight loosening due to vibration, leading to a decrease in locking force and even causing problems such as unstable FPC connection and signal transmission interruption. Although some designs use a spring-return snap-fit ​​structure, it can only provide unidirectional locking force and lacks an effective mechanism to maintain a stable locking force over a long period in a vibrating environment, resulting in limited vibration resistance and insufficient reliability. To solve the above problems, a rear-hinged FPC connector is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rear-hinged FPC connector to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a rear-hinged FPC connector, comprising a connector body and a rear cover, the rear cover being rotatably connected to the connector body. The connector body is provided with a locking assembly symmetrically arranged with respect to the rear cover. The rear cover is provided with a movable member that cooperates with the locking assembly and an elastic member that provides a restoring force to the movable member. The locking assembly includes a connecting rod fixedly disposed on the inner wall of the connector body and a stop fixedly disposed at the end of the connecting rod. When the rear cover is rotated to the pressing position, the locking assembly can compress the elastic member through the interaction between the movable member and the inclined surface of the stop. Subsequently, under the restoring action of the elastic member, the movable member is driven to move below the stop and lock, thereby restricting the opening of the rear cover.

[0006] Preferably, the movable component includes a movable rod slidably connected to the rear cover and a pressing block fixed to one end of the movable rod. The elastic component is a first spring sleeved on the periphery of the movable rod. The two ends of the first spring are fixedly connected to the pressing block and the rear cover, respectively. Annular grooves are provided on both sides of the rear cover. One end of the movable rod extends into the annular groove. The pressing block and the stop block are both wedge-shaped blocks, and their inclined surfaces cooperate with each other.

[0007] Preferably, the upper surface of the rear cover is provided with several strip grooves, and a lever is slidably disposed in the strip grooves, the bottom end of the lever being fixedly connected to the movable rod.

[0008] Preferably, an unlocking tool is provided in cooperation with the locking assembly. The unlocking tool includes a tool frame, and pressing mechanisms that can move in opposite directions are provided at both ends of the tool frame. One end of the pressing mechanism is provided with a driving part that contacts the lever.

[0009] Preferably, the pressing mechanism includes a pressing plate, a second spring, and a pressing rod. Two first sliding grooves are formed on one surface of the tool frame, and two second sliding grooves are formed on the other surface of the tool frame. The first sliding grooves are connected to the second sliding grooves. The second spring is fixedly disposed on the inner wall of the first sliding groove. One end of the second spring is fixedly connected to the pressing plate. The pressing plate is slidably engaged with the first sliding groove. The pressing rod is slidably engaged with the second sliding groove. One end of the pressing rod is fixedly connected to the pressing plate.

[0010] Preferably, a rubber sheet is adhered to one surface of the pressing plate, and a plurality of anti-slip textures are provided on one surface of the pressing rod.

[0011] Preferably, both ends of the tool frame are fixedly connected to positioning frames, and the rear cover is fixedly provided with positioning blocks that cooperate with the positioning frames, with the positioning frames fitted around the periphery of the positioning blocks.

[0012] This utility model has the following beneficial effects: 1. This utility model improves the locking effect of the rear cover against vibration. Specifically, it is achieved by setting a wedge-shaped stop and a wedge-shaped extrusion block to cooperate with each other. When the rear cover is closed, the inclined surface guides the extrusion block to slide and compress the spring. After passing the critical point, the spring resets and drives the extrusion block to enter below the stop, forming a self-locking rigid constraint on the stop from below, thereby effectively resisting vibration and preventing the rear cover from loosening and rebounding. 2. This utility model realizes the function of quick unlocking of the double-sided locking mechanism in a small space. Specifically, by setting up a lever and a dedicated unlocking tool, the user can squeeze the pressing rods on both sides of the tool, and the force is transmitted to the rubber plate through the spring and pressing plate, thereby synchronously driving the two levers and the movable rods connected to them to move in opposite directions, so that the squeezing block can be smoothly released from the stop block to complete the unlocking, which solves the problem of difficult manual unlocking of micro connectors.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figures 1-7 As shown, this utility model is a rear-hinged FPC connector, including a connector body 1 and a rear-hinged cover 2. The rear-hinged cover 2 is rotatably connected to the connector body 1. The connector body 1 is provided with locking components symmetrically arranged with respect to the rear-hinged cover 2. Each locking component includes a connecting rod 11 fixedly arranged on the inner wall of the connector body 1, and a wedge-shaped stop 12 fixed at the end of the connecting rod 11. The rear cover 2 is provided with a movable part and an elastic part that cooperate with the locking assembly; specifically, annular grooves 13 are provided on both sides of the rear cover 2, and the movable rod 8 is slidably disposed in the annular grooves 13; a wedge-shaped pressing block 10 is fixedly connected to one end of the movable rod 8 facing the inside of the connector body 1, and the inclined surface of the pressing block 10 matches the inclined surface of the stop block 12; a set of first springs 9 are sleeved on the circumferential side of the movable rod 8, and its two ends are fixedly connected to the pressing block 10 and the rear cover 2 respectively, providing the movable rod 8 and the pressing block 10 with a return elastic force toward the locking position.

[0020] When the user rotates the rear cover 2 to the closed and pressed position, the inclined surface of the pressing block 10 contacts and interacts with the inclined surface of the stop block 12. As the rear cover 2 continues to be pressed down, the guiding effect of the inclined surface forces the pressing block 10 to drive the movable rod 8 to slide along the annular groove 13 into the rear cover 2, thereby compressing the first spring 9. When the pressing block 10 slides past the apex of the inclined surface of the stop block 12, its thrust on the movable rod 8 disappears instantly. At this time, the compressed first spring 9 releases its elastic potential energy, driving the movable rod 8 and the pressing block 10 to quickly return to their original position, so that the pressing block 10 eventually moves to directly below the stop block 12. Through this mechanism, the stop block 12 is stuck above the pressing block 10, thereby restricting the opening of the rear cover 2 and realizing the vibration anti-loosening function.

[0021] A strip groove 4 is provided on the upper surface of the rear cover 2, and a lever 5 is slidably arranged in the groove. The bottom end of the lever 5 is fixedly connected to the tail of the movable rod 8. Therefore, pushing the lever 5 can directly control the movement of the movable rod 8 and the pressing block 10.

[0022] The locking assembly is coupled with a dedicated unlocking tool, which is an independent tool frame 3 capable of simultaneously driving the levers 5 on both sides. Both ends of the tool frame 3 are equipped with opposing pressing mechanisms. Each pressing mechanism includes a pressing plate 15 slidably disposed within a first slide groove 14, and a pressing rod 18 slidably disposed within a second slide groove 20. One end of the pressing rod 18 is fixedly connected to the pressing plate 15. A second spring 16 is fixed to the inner wall of the first slide groove 14, and its other end is connected to the pressing plate. The 15 connection provides a restoring force for the pressing mechanism; a rubber plate 17 is bonded to the inner side of the pressing plate 15, which serves as the driving part and contacts the lever 5 to increase friction and prevent slippage; the surface of the pressing lever 18 is machined with anti-slip texture 19 to ensure that the fingers will not slip during operation; in order to achieve quick and accurate tool positioning, positioning frames 7 are fixed at both ends of the tool frame 3, and positioning blocks 6 are correspondingly fixed on the rear cover 2; in use, the positioning frames 7 are fitted onto the periphery of the positioning blocks 6 to complete the installation and positioning of the tool.

[0023] When unlocking is required, align the positioning frame 7 of the unlocking tool with and place it on the positioning block 6 of the rear cover 2; then, the user pinches the two pressing rods 18 with two fingers, the pressing rods 18 push the pressing plate 15 to move inward against the force of the second spring 16, and transmit the force to the lever 5 through the rubber plate 17; after the lever 5 is driven, it drives the movable rod 8 and the squeezing block 10 to move towards each other, so that the squeezing block 10 disengages from under the stop block 12, and the locking state is released; at this time, the user can directly lift the rear cover 2 by pinching the pressing rods 18.

[0024] Working principle: During the locking process, when the operator closes the rear cover 2 from the open state toward the connector body 1, the movable rod 8 fixed on the rear cover and the wedge-shaped pressing block 10 installed at its end move accordingly; just before reaching the fully closed position, the inclined surface of the pressing block 10 begins to contact the inclined surface of the wedge-shaped stop 12 fixed on the connector body 1; the interaction of the inclined surfaces generates a horizontal component force, which overcomes the elastic force of the first spring 9, pushing the movable rod 8 to slide inward in the annular groove 13 of the rear cover, thereby compressing the first spring 9. Its energy storage; when the extrusion block 10 completely slides past the apex of the inclined surface of the stop block 12, the horizontal component force disappears instantly; the compressed first spring 9 immediately releases its stored elastic potential energy, driving the movable rod 8 and the extrusion block 10 to quickly return to their original positions, so that the top plane of the extrusion block 10 eventually moves below the bottom plane of the stop block 12; this process forms a "midpoint self-locking", and the stop block 12 is firmly locked on the extrusion block 10, thereby mechanically restricting the opening of the rear cover 2, effectively resisting the risk of loosening caused by vibration, and completing a highly reliable locking.

[0025] During the unlocking process, due to the miniaturized structure, manual operation is difficult; therefore, a special unlocking tool is required. The user first precisely aligns and fits the tool frame 3 with the positioning block 6 on the rear cover 2 via the positioning frame 7 on it. Then, the user simultaneously pinches the pressing rods 18 on both sides of the tool with their thumb and forefinger. The inward movement of the pressing rods 18 pushes the pressing plate 15 to slide in the first groove 14 of the tool frame 3 and compresses the second spring 16. The rubber plate 17 fixed to the pressing plate 15 moves accordingly and contacts and pushes the lever 5 on the rear cover 2 with its high friction surface. Since the bottom end of the lever 5 is fixedly connected to the movable rod 8, the movement of the lever 5 directly drives the two movable rods 8 to overcome the force of their first spring 9 and move precisely in opposite directions. This causes the two pressing blocks 10 to move out from under their respective corresponding stops 12 simultaneously, and the locking state is safely and smoothly released. After the lock is released, the user does not need to change the grip position and can directly pinch the pressing rod 18 to lift the rear cover 2 upward, making the operation smooth and convenient.
