Description

Technical Field

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

[0002] The FPC connector is an electrical connection element designed specifically for flexible printed circuits (FPCs) or flexible flat cables (FFCs). It is used to achieve reliable connections between flexible electronic components. Its core features are high density, light weight, and bending resistance. It is widely used in smartphones, 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 includes a base, a terminal plugged into the base, and a cover snapped with the terminal. A mounting cavity is provided through the base, and a relief portion is provided on the mounting cavity at a position corresponding to the cover. 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 relief 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. 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 (Chinese patent with announcement number CN219874230U and announcement date 2023-10-20) a structurally stable flip-cover FPC connector, comprising: an FPC connector body, equipped with a matching flip cover; a holding block, slidably arranged on the flip cover, and both ends of the holding block are connected to limit blocks; a clamping block, slidably arranged on the flip cover, and the end of the clamping block away from the flip cover is inserted into the interior of the FPC connector body; the beneficial effect is: by arranging an elastic holding block on the flip cover, the clamping of the flip cover on the PCB board is strengthened, making it 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; 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 clamping block and the fixing groove, which strengthens the connection between the flip cover and the FPC connector body, facilitates the disassembly of the flip cover, and facilitates 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, the industry has begun to popularize graphene cables 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

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

[0010] Preferably, the terminal resistance mechanism includes a limiting slide rod, which is nested and slidably connected to the inner side of the connector body, and the outer end of the limiting slide rod is fixedly connected to the rear pressure plate of the flip cover, and the inner end of the limiting slide rod is fixedly connected to the terminal pressure plate.

[0011] Preferably, the rear pressure plate of the flip cover and the terminal body are spaced apart, and the edge of the rear pressure plate of the flip cover is arranged in an arc-shaped structure, and the side of the rear pressure plate of the flip cover is in conflict with the outer side wall of the flip cover body in the open state, and the limiting slide rod forms a sliding structure with the limiting slide rod through the conflict between the rear pressure 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 interference of the terminal pressing plate.

[0013] Preferably, the soft cable interference mechanism includes a limiting groove, which is opened on the front side of the connector body, and the limiting plate is nested in the internal sliding connection of the limiting groove, and the outer end of the sliding connection is fixedly connected to the flip cover front pressure plate, and the connector body is fixedly connected between the lower surface of the flip cover front pressure plate and the interior of the connector body, and the upper surface of the flip cover front pressure plate interferes with the inner side wall of the flip cover body in the closed state.

[0014] Preferably, an adjustment slot is provided in an inclined shape inside the front pressure plate of the flip cover, and a resistance rod is nested and slidably connected inside the adjustment slot, and the outer end of the resistance rod is fixedly connected to a connecting plate, and the outer end of the connecting plate is fixedly connected to a flexible cable resistance 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 contacts the side of the lower surface of the flexible cable body, and the flexible cable contact plate moves laterally under the driving action of the front pressure plate of the flip cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] A graphene layer, designed to enhance conductivity and heat dissipation, is located on the underside of the flexible cable body. An inclined guide on the front side of the connector body guides the flexible cable body during insertion and removal, minimizing contact between the graphene and the plastic wall and preventing damage to the graphene layer.

[0018] Elastic protrusions are provided, and the local deformation of the flexibly provided elastic protrusions absorbs the friction shear force when the flexible cable body is docked and plugged in, thereby dispersing and buffering the stress of the plugging and unplugging, and further avoiding the phenomenon of the graphene layer falling off during plugging and unplugging.

[0019] 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 bar to move downward synchronously, thereby contacting the terminal body to cause it to deform. At this time, the terminal body with the side deformed downward does not contact the lower surface of the flexible cable body. By reducing the contact of the terminal body with the lower side of the flexible cable body, the graphene coating provided on the lower side of the flexible cable body is further protected.

[0020] When the flip cover body is flipped back, the front side of the flip cover body no longer contacts the upper surface of the flip cover front pressure plate. At this time, the flip cover front pressure plate moves upward and contacts the resistance rod, causing the resistance rod to slide. At this time, the flexible cable resistance plate moves laterally, and the flexible cable body can move upward through the inclined edge of the flexible cable resistance plate, thereby reducing the contact area between the flexible cable body and the plastic surface, further preventing the plastic surface from damaging the graphene arranged on the lower surface of the flexible cable body.

[0021] 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 limit plate can be limited by the limit groove, 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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The technical solution shown in the present invention provides the following technical solution: a graphene cable coating anti-slip FPC connector, disclosing an inclined guide part 101, which can reduce the contact area between the soft cable body 4 and the plastic: a flip cover body 3 is rotatably arranged above the connector body 1, and a terminal body 2 is docked inside the connector body 1, and a soft cable body 4 is docked inside the connector body 1, a soft cable contact plate 13 is arranged on the front side of the inner part of the connector body 1, and an inclined guide part 101 is provided on the front side of the connector body 1 to reduce the contact area between the soft cable body 4 and the plastic, elastic protrusions 11 are distributed in an array on the contact surface between the interior of the connector body 1 and the soft cable body 4, and the friction shear force of the soft cable body 4 can be absorbed by the local deformation of the elastic protrusions 11, the inner wall of the inclined guide part 101 is coated with polytetrafluoroethylene for reducing the friction coefficient, and the inclined guide part 101 and the terminal body 2 are spaced apart, and the length of the connector body 1 is greater than half the inner length of the docking groove of the connector body 1.

[0034] A graphene layer that can enhance its conductivity and heat dissipation is provided on the lower side of the flexible flat cable body 4. At the same time, an inclined guide portion 101 with a length greater than half of the interior of its docking slot is provided on the front side of the connector body 1. The inclined guide portion 101 can guide the flexible flat cable body 4 for docking and plugging, thereby reducing the contact area between the graphene and the plastic wall and avoiding damage to the graphene layer. Elastic protrusions 11 are also distributed in an array inside the connector body 1. The local deformation of the flexibly arranged elastic protrusions 11 absorbs the frictional 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 during plugging and unplugging.

[0035] Example 2: Figure 1 、 Figure 2 and Figure 4-Figure 6 The technical solution shown in the figure, the present invention provides the following technical solutions: a graphene cable coating anti-slip FPC connector, disclosing a terminal resistance mechanism, through which the terminal resistance mechanism can resist the terminal body 2, causing the terminal body 2 to deform, thereby reducing the contact area between the terminal body 2 and the flexible cable body 4, and preventing the graphene from falling off: a movable groove 12 is opened inside the rear side of the connector body 1, and a terminal resistance mechanism is provided inside the movable groove 12, and 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 limiting slide 6, which is nested and slidably connected to the inner side of the connector body 1. The outer end of the limiting slide 6 is fixedly connected to the flip cover rear pressure plate 5, and the inner end of the limiting slide 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 6 forms a sliding structure with the limiting slide 6 through the interference action of 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 interference action of the terminal pressure plate 7.

[0036] When the flexible cable body 4 is docked and plugged in, the flip cover body 3 is flipped open backward. At this time, the rear side of the flip cover body 3 can contact the flip cover rear pressure plate 5 set on the rear upper surface of the connector body 1, thereby making the flip cover rear pressure plate 5 move downward. The moving flip cover rear pressure plate 5 can simultaneously drive the limiting slide 6 to slide along the inside of the connector body 1, thereby making the terminal pressure plate 7 fixed at the lower end of the limiting slide 6 move downward synchronously and contact 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 contact the lower surface of the flexible cable body 4, so that the flexible cable body 4 can be better pulled out. By reducing the contact of the terminal body 2 with the lower side of the flexible cable body 4, the graphene coating set on the lower side of the flexible cable body 4 is further protected.

[0037] Example 3: Figure 1 、 Figure 3 and Figure 7-Figure 9 The technical solution shown in the figure, the present invention provides the following technical solutions: a graphene cable coating anti-slip FPC connector, discloses a soft cable resistance mechanism, through which the soft cable resistance mechanism can resist and lift the soft cable body 4 when the flip body 3 is opened, thereby reducing the contact area between the soft cable body 4 and the plastic: a soft cable resistance mechanism is provided 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 by rotating the flip body 3, and the soft cable resistance mechanism includes a limiting groove 9, which is provided on the front side of the connector body 1, and the internal nesting of the limiting groove 9 is slidably connected to the limiting plate 10, and the outer end of the sliding connection is fixedly connected to the flip 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 interior 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. The interior of the flip cover front pressure plate 17 is inclined to open an adjustment groove 18, and the interior of the adjustment groove 18 is nested and slidably connected with a resistance rod 16, and the outer end of the resistance rod 16 is fixedly connected to the connecting plate 15, and the outer end of the connecting plate 15 is fixedly connected to the soft cable resistance plate 13. The side of the soft cable resistance plate 13 is arranged in an inclined structure, and the inclined side of the soft cable resistance plate 13 conflicts with the side of the lower surface of the soft cable body 4. The soft cable resistance plate 13 is driven by the flip cover front pressure plate 17 to move laterally.

[0038] When the flip cover body 3 is flipped back, the front side of the flip cover body 3 no longer contacts the upper surface of the flip cover front pressure plate 17. At this time, the flip cover front pressure plate 17 moves upward under the driving force of the elastic force of the second spring 14. When the flip cover front pressure plate 17 moves up and down under the driving force of the elastic force and the resistance force of the flip cover body 3, the limit plate 10 can be driven to slide along the limit groove 9 opened on the side of the connector body 1. The limit groove 9 can limit the limit plate 10, thereby further limiting the flip cover front pressure plate 17, so that the flip cover front pressure plate 17 can move more stably. The adjustment groove 18 opened on the inner side of the front pressure plate 17 of the cover can interfere with the resistance rod 16, so that the resistance rod 16 slides along the inside of the adjustment groove 18. During the sliding process, the resistance rod 16 can synchronously drive the flexible cable resistance plate 13 to move laterally through the connecting plate 15. When the flexible cable resistance plate 13 moves, it can extend into the lower surface of the flexible cable body 4. At the same time, the flexible cable body 4 can move upward through the inclined edge of the flexible cable resistance plate 13, thereby reducing the contact area between the flexible cable body 4 and the plastic surface, further preventing the plastic surface from damaging the graphene provided on the lower surface of the flexible cable body 4.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
