Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a graphene cable coating anti-detachment type FPC connector. Background Art

[0002] The FPC connector is an electrical connection element designed specifically for flexible printed circuits (FPC) or flexible flat cables (FFC). It is used to achieve reliable connections between flexible electronic components. Its core features are high density, light weight, and resistance to bending. It is widely used in smart phones, folding devices, camera modules, automotive electronics and other fields.

[0003] Prior art 1 (Chinese patent with announcement number CN221805898U and announcement date 2024-10-01) An FPC connector, comprising a base, a terminal plugged into the base and a cover snapped onto the terminal, a mounting cavity is provided through the base, and a yield portion is provided on the mounting cavity at a position corresponding to the cover, and the above-mentioned FPC connector is adopted to realize the overall assembly of the connector by cooperating with the cover and the terminal, wherein a yield portion is provided on the inner wall of the mounting cavity of the base to avoid interference between the driven plate of the rear terminal and the base after the cover is snapped, thereby improving the overall assembly efficiency and ensuring the connection stability, and at the same time, through the cooperation of the positioning protrusion with the upper limit groove and the limit stopper of the base, not only can the cover be limited in the vertical direction, but also the cover can be restricted from falling off after assembly, thereby further improving the overall connection strength and assembly reliability. There is also prior art 2 (a Chinese patent with announcement number CN219874230U and announcement date of 2023-10-20), a structurally stable flip-cover FPC connector, comprising: an FPC connector body, on which a matching flip cover is installed; a holding block, which is slidably arranged on the flip cover, and both ends of the holding block are connected to limit blocks; a card block, which is slidably arranged on the flip cover, and the end of the card block away from the flip cover is plugged into the interior of the FPC connector body; the beneficial effect is: by arranging an elastic holding block on the flip cover to strengthen the clamping of the flip cover on the PCB board, it is difficult for the PCB board and the terminals on the FPC connector body to be separated, thereby making the connection between the FPC connector body and the PCB board more stable, and when not connected, the holding block can cover the terminals of the FPC connector body to prevent residual dirt from appearing on the terminal surface; at the same time, the FPC connector body and the flip cover are connected by the cooperation of the card block and the fixing groove, which strengthens the connection between the flip cover and the FPC connector body, and facilitates the disassembly of the flip cover and the cleaning of the holding block.

[0004] Although the FPC connector in the existing technology can prevent the flip cover from falling off and is convenient for cleaning, with the continuous upgrading and transformation of FFC flexible cables, graphene cables have begun to be popular in the industry to replace the original copper foil contacts. Graphene can enhance the conductivity and heat dissipation of the cables, but its graphene coating is easy to fall off. When the flexible cable body is docked and plugged in, the graphene arranged underneath it will be damaged, thus affecting the subsequent use effect.

[0005] Therefore, we propose a graphene cable coating anti-slip FPC connector to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a graphene cable coating anti-detachment FPC connector to solve the problem raised by the above background technology that with the continuous upgrading and transformation of FFC soft cables in the market, the industry has begun to popularize graphene cables to replace original copper foil contacts. The conductivity and heat dissipation of the cables can be enhanced by graphene, but the graphene coating is easy to fall off. When the soft cable body is docked and plugged in, the graphene arranged underneath it will be damaged, thereby affecting the subsequent use effect.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a graphene cable coating anti-detachment FPC connector, comprising a connector body, a flip cover body is rotatably arranged on the top of the connector body, and a terminal body is butt-jointedly arranged inside the connector body, and a soft cable body is butt-jointedly arranged inside the connector body, a movable groove is opened inside the rear side of the connector body, and a terminal resistance mechanism is arranged inside the movable groove, the terminal resistance mechanism resists the terminal body through the flip cover body to reduce the contact with the soft cable body, a soft cable resistance plate is arranged on the inner front side of the connector body, and a soft cable resistance mechanism is arranged between the soft cable resistance plate and the connector body, and the soft cable resistance mechanism realizes resistance and lifting of the soft cable body through the rotation of the flip cover body.

[0008] Preferably, an inclined guide portion is provided on the front side of the connector body to reduce the contact area between the flexible flat cable body and the plastic, and elastic protrusions are distributed in an array on the contact surface between the interior of the connector body and the flexible flat cable body, and the frictional shear force of the flexible flat cable body can be absorbed by local deformation of the elastic protrusions.

[0009] Preferably, the inner wall of the inclined guide portion is coated with polytetrafluoroethylene for reducing the friction coefficient, and the inclined guide portion and the terminal body are spaced apart and distributed, and the length of the connector body is greater than half of the inner length of the connector body docking groove.

[0010] Preferably, the terminal contact mechanism includes a limiting slide bar which is nested and slidably connected inside the connector body. The outer end of the limiting slide bar is fixedly connected with a rear cover pressing plate of the flip cover, and the inner end of the limiting slide bar is fixedly connected with a terminal pressing plate.

[0011] Preferably, the rear cover pressing plate of the flip cover and the terminal body are arranged at intervals. The edge of the rear cover pressing plate of the flip cover is arranged in an arc structure, and the side of the rear cover pressing plate of the flip cover abuts against the outer side wall of the flip cover body in the opened state. The limiting slide bar forms a sliding structure with the limiting slide bar through the abutting action of the rear cover pressing plate of the flip cover and the flip cover body.

[0012] Preferably, a first spring is fixedly connected between the upper surface of the terminal pressing plate and the inner wall of the movable groove. The terminal pressing plate is located directly above the side of the terminal body, and the terminal body is deformed by the abutting action of the terminal pressing plate.

[0013] Preferably, the flexible cable contact mechanism includes a limiting groove which is opened at the front side of the connector body. A limiting plate is nested and slidably connected inside the limiting groove. The outer end of the sliding connection is fixedly connected with a front cover pressing plate of the flip cover. At the same time, a connector body is fixedly connected between the lower surface of the front cover pressing plate of the flip cover and the inside of the connector body. The upper surface of the front cover pressing plate of the flip cover abuts against the inner side wall of the flip cover body in the closed state.

[0014] Preferably, an adjusting groove is obliquely opened inside the front cover pressing plate of the flip cover. A contact rod is nested and slidably connected inside the adjusting groove. The outer end of the contact rod is fixedly connected with a connecting plate, and the outer end of the connecting plate is fixedly connected with a flexible cable contact plate.

[0015] Preferably, the side of the flexible cable contact plate is arranged in an inclined structure, and the inclined side of the flexible cable contact plate abuts against the side of the lower surface of the flexible cable body. The flexible cable contact plate moves horizontally under the driving action of the front cover pressing plate of the flip cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: A graphene layer which can enhance the electrical conductivity and heat dissipation is arranged on the lower side of the flexible cable body. The flexible cable body can be guided for butt joint plugging and unplugging through the inclined guiding part arranged on the front side of the connector body, so as to reduce the contact area between the graphene and the plastic wall and avoid damage to the graphene layer.

[0017] Elastic bumps are arranged. The local deformation of the elastically arranged elastic bumps absorbs the frictional shear force during the butt joint plugging and unplugging of the flexible cable body, so as to disperse and buffer the stress of its plugging and unplugging, and further avoid the phenomenon that the graphene layer falls off due to plugging and unplugging.

[0018] When the flip cover body is flipped back, the rear side surface of the flip cover body contacts and squeezes the rear pressure plate of the flip cover to move downward, and drives the terminal pressure plate fixed at the lower end of the limiting slide rod to move downward synchronously, thereby contacting the terminal body to deform it. At this time, the terminal body with the side deformed downward does not contact the lower surface of the flexible cable body, and the contact of the terminal body with the lower side of the flexible cable body is reduced, thereby further protecting the graphene coating arranged on the lower side of the flexible cable body.

[0019] When the flip cover body is flipped back, the front side of the flip cover body no longer resists the upper surface of the flip cover front pressure plate. At this time, the flip cover front pressure plate moves upward and resists the resistance rod, so that the resistance rod slides. At this time, the soft cable resistance plate moves laterally, and the soft cable body can move upward through the inclined edge of the soft cable resistance plate, thereby reducing the contact area between the soft cable body and the plastic surface, further preventing the plastic surface from damaging the graphene arranged on the lower surface of the soft cable body.

[0020] When the front pressure plate of the flip cover moves up and down driven by the elastic force of the second spring and the resistance force of the flip cover body, the limiting groove can limit the limiting plate, thereby further limiting the front pressure plate of the flip cover, so that the front pressure plate of the flip cover can move more stably.

[0025] A graphene layer that can enhance its conductivity and heat dissipation is arranged on the lower side of the flexible flat cable body 4. At the same time, an inclined guide portion 101 whose length is greater than half of the inside of its docking groove is arranged on the front side of the connector body 1. The flexible flat cable body 4 can be guided for docking and plugging through the inclined guide portion 101, thereby reducing the contact area between the graphene and the plastic wall and avoiding damage to the graphene layer. Elastic protrusions 11 are also arranged in an array inside the connector body 1. The local deformation of the flexibly arranged elastic protrusions 11 absorbs the friction shear force of the flexible flat cable body 4 during docking and plugging, thereby dispersing and buffering the stress of its plugging and unplugging, further avoiding the phenomenon of the graphene layer falling off due to plugging and unplugging.

[0026] Embodiment 2: Figure 1 , Figure 2 and Figures 4 - 6 The technical scheme shown in the figure, the present invention provides the following technical scheme: a graphene cable coating anti-dropping FPC connector, disclosing a terminal resistance mechanism, through which the terminal resistance mechanism can resist the terminal body 2, so that the terminal body 2 is deformed, thereby reducing the contact area between the terminal body 2 and the flexible cable body 4, and preventing the graphene from falling off: an active groove 12 is opened inside the rear side of the connector body 1, and a terminal resistance mechanism is arranged inside the active groove 12, the terminal resistance mechanism resists the terminal body 2 through the flip body 3, thereby reducing the contact with the flexible cable body 4, and the terminal resistance mechanism includes a limit slide bar 6, and the limit slide bar 6 is nested and slidably connected to the inner side of the connector body 1 The outer end of the limiting slide bar 6 is fixedly connected to the flip cover rear pressure plate 5, and the inner end of the limiting slide bar 6 is fixedly connected to the terminal pressure plate 7. The flip cover rear pressure plate 5 and the terminal body 2 are spaced apart, and the edge of the flip cover rear pressure plate 5 is arranged in an arc-shaped structure, and the side of the flip cover rear pressure plate 5 is in conflict with the outer side wall of the flip cover body 3 in the opened state. The limiting slide bar 6 forms a sliding structure with the limiting slide bar 6 through the conflict between the flip cover rear pressure plate 5 and the flip cover body 3. A first spring 8 is fixedly connected between the upper surface of the terminal pressure plate 7 and the inner wall of the movable groove 12. The terminal pressure plate 7 is located directly above the side of the terminal body 2, and the terminal body 2 is deformed by the conflict of the terminal pressure plate 7.

[0027] When the flexible flat cable body 4 is docked and plugged in, the flip cover body 3 is flipped back. At this time, the rear side surface of the flip cover body 3 can resist the flip cover rear pressure plate 5 set on the rear upper surface of the connector body 1, so that the flip cover rear pressure plate 5 moves downward, and the moving flip cover rear pressure plate 5 can simultaneously drive the limiting slide bar 6 to slide along the inside of the connector body 1, so that the terminal pressure plate 7 fixed at the lower end of the limiting slide bar 6 moves downward synchronously and resists the side of the terminal body 2, so that the side of the terminal body 2 is deformed downward. At this time, the terminal body 2 with the side deformed downward does not resist the lower surface of the flexible flat cable body 4, so that the flexible flat cable body 4 can be better pulled out, and the resistance of the terminal body 2 to the lower side of the flexible flat cable body 4 is reduced, thereby further protecting the graphene coating set on the lower side of the flexible flat cable body 4.

[0028] Embodiment 3: Figure 1 , Figure 3 and Figures 7 - 9 The technical scheme shown in the invention provides the following technical scheme: a graphene cable coating anti-slip FPC connector, disclosing a soft cable resistance mechanism, through which the soft cable resistance mechanism can resist and lift the soft cable body 4 when the flip cover body 3 is opened, thereby reducing the contact area between the soft cable body 4 and the plastic: a soft cable resistance mechanism is arranged between the soft cable resistance plate 13 and the connector body 1, and the soft cable resistance mechanism realizes the resistance and lifting of the soft cable body 4 through the rotation of the flip cover body 3, and the soft cable resistance mechanism includes a limiting groove 9, the limiting groove 9 is arranged on the front side of the connector body 1, and the limiting groove 9 is internally nested and slidably connected to the limiting plate 10, and the outer end of the sliding connection is fixedly connected to the flip cover front pressure plate 17 At the same time, the connector body 1 is fixedly connected between the lower surface of the flip cover front pressure plate 17 and the inside of the connector body 1, and the upper surface of the flip cover front pressure plate 17 conflicts with the inner side wall of the flip cover body 3 in the closed state.

[0029] When the flip cover body 3 is turned backward, the front side of the flip cover body 3 no longer abuts against the upper surface of the front pressing plate 17 of the flip cover. At this time, the front pressing plate 17 of the flip cover moves upward under the elastic force of the second spring 14. When the front pressing plate 17 of the flip cover moves up and down under the drive of the elastic force and the abutting force of the flip cover body 3, it can drive the limiting plate 10 to slide inside the limiting groove 9 opened on the side of the connector body 1. The limiting plate 10 can be limited through the limiting groove 9, so as to further limit the front pressing plate 17 of the flip cover, making the front pressing plate 17 of the flip cover move more stably. At this time, the adjusting groove 18 opened inside the front pressing plate 17 of the flip cover can abut against the abutting rod 16, so that the abutting rod 16 slides inside the adjusting groove 18. During the sliding process of the abutting rod 16, it can synchronously drive the flexible cable abutting plate 13 to move horizontally through the connecting plate 15. When the flexible cable abutting plate 13 is moving, it can extend into the lower surface of the flexible cable body 4, and at the same time, the flexible cable body 4 can move upward through the inclined edge of the flexible cable abutting plate 13, thereby reducing the contact area between the flexible cable body 4 and the plastic surface, and further preventing the plastic surface from damaging the graphene arranged on the lower surface of the flexible cable body 4.
