Description
Technical Field
[0001] The invention relates to the technical field of electronic connection, and in particular to an anti-biased insertion FFC cable assembly. Background Art
[0002] In electronic devices, FFC (Flexible Flannel Cable) cables are widely used for high-density electrical connections. Their advantages include good flexibility, easy installation, and compact structure. However, traditional FFC cable connectors are prone to problems such as inaccurate docking, misaligned insertion, and mechanical damage during multiple connection and disassembly processes. These problems not only affect the stability of electrical connections, but may also lead to reduced device performance or shortened service life.
[0003] Existing FFC cable assemblies are usually connected by manual docking, but due to the lack of precise positioning structures at both ends of the connector, users are prone to misalignment when plugging in. Once misaligned, the connector terminals will be unevenly stressed or even deformed, which may cause connection failure in severe cases. In addition, multiple connections and plugging and unplugging will aggravate the mechanical wear of the interface and increase equipment maintenance costs. In order to improve the stability of the connection, some existing technologies have introduced limiting structures or locking mechanisms. However, these solutions have problems such as complex design, difficult assembly or insufficient reliability. For example, the elastic buckle or threaded locking structure in some designs can play a certain fixing role, but its operation process is relatively cumbersome, and it is difficult to improve the connection efficiency while ensuring precise positioning. In addition, some existing locking mechanisms may still loosen when subjected to vibration or external force, making it difficult to meet the needs of high-reliability connections. Summary of the invention
[0004] The purpose of the present invention is to provide an anti-biased insertion FFC cable assembly to solve the problems existing in the prior art.

[0009] A handle is provided on the outer wall of the outer ring. By rotating the outer ring, the limit column slides along the annular groove to the inner hole and is pushed into the inner hole under the action of the spring, so that the FFC cable connector 1 is firmly connected with the FFC cable connector 2.
[0010] Preferably, the insertion rod cooperates with the fixing block to achieve initial positioning of the FFC cable connector 2 when it is inserted into the FFC cable connector 1.
[0011] Preferably, the limiting column slides in the vertical sliding groove along the insertion direction to guide the FFC cable connector 2 to be accurately inserted into the FFC cable connector 1.
[0012] Preferably, an annular groove is provided on the inner wall of the outer sleeve.
[0013] Preferably, the spring is compressed in the sliding cavity to store elastic potential energy, and when the limiting column moves to the inner hole, the elastic force is released to push the limiting column into the inner hole.
[0014] Preferably, the handle is a ring-shaped structure and is integrally formed with the outer ring.

[0020] The anti-biased insertion FFC cable assembly can achieve accurate initial positioning during the plugging process through the cooperation of the plug rod on the FFC cable connector 2 and the fixing blocks on both sides of the FFC cable connector 1 jacket, avoiding the biased insertion phenomenon caused by inaccurate positioning in the traditional FFC cable assembly, thereby protecting the connector terminals and reducing mechanical damage. The outer ring in the assembly is designed with a limit column, an annular slide groove and a vertical slide groove, so that the limit column enters the inner hole under the elastic force of the spring to complete the locking, ensuring that the FFC cable connector 1 and the FFC cable connector 2 are firmly connected after insertion, thereby preventing loosening due to vibration or external force, and improving The stability and reliability of the connection, the handle set on the outer wall of the outer ring is convenient for manual rotation of the outer ring, and the locking process of the limit column can be completed in a simple operation without additional complicated operations, which greatly improves the connection efficiency of the FFC cable. The spring adopts a compression coil spring design, and provides a more stable elastic reset function through the one-piece structure of the sliding cavity and the outer ring, so that the component can maintain stable performance during multiple plug-in and unplug uses, reducing the mechanical wear of the interface and extending the service life of the component. The outer jacket is designed with a tapered structure at both ends, which can effectively guide the FFC cable connector 2 to be smoothly inserted into the FFC cable connector 1, improving the adaptability of the component. At the same time, the vertical slide groove and the annular slide groove are connected by an arc transition, which reduces the friction resistance of the limit column when sliding and optimizes the smoothness of the overall connection process. The sliding cavity and the outer ring are one-piece design, which reduces the complexity of processing and assembly. At the same time, the use of wear-resistant materials and optimized structural design improves the strength and durability of the component, thereby reducing the manufacturing cost.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.
[0027] like Figure 1-Figure 4 As shown, the present invention provides a technical solution: an anti-biased insertion FFC cable assembly, including an FFC cable connector 1, a jacket 3 is provided on the outside of the FFC cable connector 1, fixed blocks 13 are provided on both sides of the jacket 3, and a vertical slide groove 5 and an inner hole 7 are provided on the FFC cable connector 1; an FFC cable connector 2, an insertion rod 12 is provided on both sides of the FFC cable connector 2; an outer ring 4, which is arranged on the outside of the FFC cable connector 2, a limiting column 10 is provided on the outer ring 4, a sliding cavity 9 is provided in the outer ring 4, a spring 8 is provided in the sliding cavity 9, and the limiting column 10 is elastically reset in the sliding cavity 9 by the thrust of the spring 8; a handle 14, a handle 14 is provided on the outer wall of the outer ring 4, and by rotating the outer ring 4, the limiting column 10 slides along the annular slide groove 6 to the inner hole 7 and is pushed into the inner hole 7 under the action of the spring 8, so that the FFC cable connector 1 is firmly connected with the FFC cable connector 2. In the above scheme, the FFC cable assembly can achieve precise docking between FFC cable connector 1 and FFC cable connector 2 2 by means of the design of the fixing block 13 on the outer sleeve 3 and the plug 12. At the same time, by rotating the outer ring 4, the limit column 10 can slide along the annular slide groove 6 to the position of the inner hole 7, and complete the reset action under the action of the spring 8, thereby making the connection more secure. The vertical slide groove 5 provides a guiding function for the limit column 10 to ensure that there is no offset during the connection process. The advantage of this embodiment is that the problem of unstable connection caused by the offset insertion of the traditional FFC cable assembly is effectively solved through the unique spring reset design and the sliding cooperation of the limit column 10. In addition, the connection operation is completed by rotating the outer ring 4, which further improves the convenience of installation and the reliability of connection.
[0028] In other possible variations, the sleeve 3 can be made of a variety of materials, such as plastic, aluminum alloy, etc.; the shape of the limit column 10 can be designed to be cylindrical, square column or other suitable shapes according to specific needs; the connection method between the outer ring 4 and the sliding cavity 9 can be snap-on or adhesive to adapt to different usage environment requirements.
[0029] The insertion rod 12 cooperates with the fixing block 13 to achieve the initial positioning of the FFC cable connector 2 when it is inserted into the FFC cable connector 1. In the above scheme, by setting the matching structure of the insertion rod 12 and the fixing block 13, the deviation phenomenon of the FFC cable connector 2 when inserted into the FFC cable connector 1 can be effectively avoided. The gap design between the fixing block 13 and the insertion rod 12 is optimized, which can reduce the resistance during the insertion process while ensuring the positioning effect, thereby improving the assembly efficiency. The advantage of this structure is that it improves the accuracy of the initial positioning, and at the same time provides good preparatory conditions for the subsequent fixation of the limit column 10, reducing the risk of assembly failure caused by positioning errors.
[0030] In the variation, the material of the plug 12 and the fixing block 13 can be selected according to actual needs, such as high-strength engineering plastics or metal alloys, with higher wear resistance; at the same time, the diameter and length of the plug 12 can be adjusted according to the usage scenario to adapt to FFC cable connectors of different specifications.
[0031] The limit column 10 slides in the vertical slide groove 5 along the insertion direction to guide the FFC cable connector 2 to be accurately inserted into the FFC cable connector 1. In the above scheme, the cooperation between the limit column 10 and the vertical slide groove 5 enables the FFC cable connector 2 to maintain precise linear motion along the insertion direction to avoid insertion failure due to directional deviation. The sliding track of the vertical slide groove 5 has been precisely designed to provide sufficient guiding support for the limit column 10 and ensure smooth sliding without jamming. The advantage of this design is that it significantly improves the accuracy and stability of the FFC cable connection while reducing the difficulty and time consumption of assembly.
[0032] In other variations, the width and depth of the vertical slide groove 5 can be adjusted according to the size of the limiting column 10; a lubricating material or coating can be added inside the slide groove to further improve the sliding performance.
[0033] An annular groove 6 is provided on the inner wall of the outer sleeve 3. In the above scheme, the setting of the annular groove 6 provides a sliding path for the limit column 10, so that it can slide smoothly to the position of the inner hole 7 under the rotation drive of the outer ring 4. The design shape of the annular groove 6 is optimized, and can provide sufficient guiding effect while ensuring smooth sliding to ensure the positioning accuracy of the limit column 10. The advantage of this structure is that through the reasonable design of the annular groove 6, the smoothness and stability of the sliding of the limit column 10 are significantly improved, while avoiding the problem of jamming that may occur during the sliding process. In other possible variations, the width and depth of the annular groove 6 can be adjusted according to the size of the limit column 10; in addition, the annular groove 6 can be provided with a coating or embedded with a wear-resistant material on the inner wall surface to improve its durability and sliding performance.
[0034] The spring 8 is compressed in the sliding cavity 9 to store elastic potential energy. When the limit column 10 moves to the inner hole 7, the elastic force is released to push the limit column 10 into the inner hole 7. In the above scheme, the role of the spring 8 is to provide a continuous thrust for the limit column 10, so that it can quickly bounce in and achieve a firm connection when it reaches the inner hole 7. The sliding cavity 9 provides a storage space for the spring 8. The compression and release process of the spring 8 in the sliding cavity 9 is precisely controlled to ensure uniform thrust and rapid reset. The advantage of this design is that it utilizes the elastic reset characteristics of the spring 8 to significantly improve the reliability and stability of the connection between the FFC cable connector 1 and the FFC cable connector 2 2, while simplifying the operation process.
[0035] In possible variations, the spring 8 may be made of different materials and forms, such as a compression coil spring, a disc spring, etc., to meet different usage requirements; the internal size and shape of the sliding cavity 9 may also be optimized according to the specifications of the spring 8.
[0036] The handle 14 is an annular structure, which is integrally formed with the outer ring 4. In the above scheme, the annular design of the handle 14 provides the user with a good grip feel, which facilitates the operation of the outer ring 4 to complete the rotation action. The annular structure makes the torque distribution more uniform, helps to reduce the resistance during the rotation operation, and improves the convenience and comfort of the operation. Integrating the handle 14 with the outer ring 4 not only improves the overall strength of the structure, but also simplifies the manufacturing process and reduces the cost. The advantage of this embodiment is that the design of the annular handle 14 makes the operation more intuitive and simple, while reducing the possibility of misoperation.
[0037] In other possible variations, the shape of the handle 14 can be designed to be non-annular, such as strip or wave, according to user needs; the handle surface can also be provided with an anti-slip texture or a soft covering layer to enhance the user experience.
[0038] The two ends of the jacket 3 are tapered structures to guide the FFC cable connector 2 to be smoothly inserted into the FFC cable connector 1. In the above scheme, the tapered structures at both ends of the jacket 3 provide effective guidance for the insertion process. The tapered design can adjust the FFC cable connector 2 to the correct position in the initial stage of insertion, thereby reducing the offset or jamming during the insertion process, and also improving the efficiency and accuracy of the plug-in. The advantage of this design is that the alignment effect of the insertion process is optimized through the tapered structure, which effectively reduces the reliance on precise operations during assembly and further enhances the user's convenience of operation.
[0039] In other possible variations, the angle and length of the tapered structure can be adjusted according to the specific size and plug-in requirements of the FFC cable; at the same time, the tapered surface can be provided with a smooth coating or lubrication treatment to further reduce the insertion resistance.
[0040] Spring 8 is a compression coil spring. In the above scheme, spring 8 is in the form of a compression coil spring, which has the advantages of compact structure, stable performance, and can provide a large elastic potential energy storage capacity in a small space. During the working process of the compression coil spring in the sliding cavity 9, the energy is stored and released through deformation, thereby pushing the limit column 10 to complete the elastic reset action. The advantage of this design is that the compression coil spring has a long service life and high working reliability, which can meet the elastic reset requirements in high-frequency use scenarios.
[0041] In other variations, different spring materials can be selected according to actual needs, such as stainless steel, alloy steel or composite materials; at the same time, the wire diameter, number of turns and elastic coefficient of the spring can also be adjusted according to the specific application.
[0042] The annular chute 6 and the vertical chute 5 are connected by an arc transition. In the above scheme, the arc transition connection design between the annular chute 6 and the vertical chute 5 can reduce the impact and jamming of the limit column 10 during the sliding process, ensuring the stability and smoothness of the sliding process. The curvature of the arc transition connection is optimized and can effectively disperse the stress concentration during sliding, thereby extending the service life of the component. The advantage of this design is that it reduces the resistance and friction on the sliding path through a smooth transition, improves the sliding efficiency, and at the same time improves the durability and reliability of the overall structure.
[0043] In other variations, the radius of curvature of the arc can be adjusted according to the sliding requirements of the limiting column 10; in addition, the transition part of the slide groove can be added with surface hardening treatment or lubricating coating to further improve the sliding performance.
[0044] The sliding cavity 9 and the outer ring 4 are an integrally formed structure. In the above scheme, the sliding cavity 9 and the outer ring 4 are designed as an integrally formed structure, which makes the manufacturing process of the component simpler and also improves the overall strength and stability. The integrally formed structure avoids the looseness or displacement problems that may occur in the traditional assembly method, and can ensure the dimensional accuracy and working reliability of the sliding cavity 9. The advantage of this design is that the integrally formed structure reduces the number of parts, simplifies the manufacturing and assembly process, and thus reduces the production cost; at the same time, the integrated design also improves the overall performance and service life of the component.
[0045] In other variations, the sliding cavity 9 and the outer ring 4 can be made by high-precision mold processing or 3D printing technology; for high-strength demand scenarios, composite materials with high wear resistance and strength can be selected for integrated design.
[0046] When using the anti-biased insertion FFC cable assembly, in order to achieve a reliable connection between the FFC cable connector 1 and the FFC cable connector 2, it is first necessary to align the insertion rods 12 on both sides 11 of the FFC cable connector 2 with the fixing blocks 13 on both sides of the outer jacket 3 of the FFC cable connector 1 for preliminary positioning. The main purpose of this design is to avoid the problem of position deviation during the connection process, and also to prevent damage to the assembly due to multiple incorrect connection operations. After completing the preliminary alignment, slowly push the FFC cable connector 2 into the FFC cable connector 1. During the insertion process, the front end of the FFC cable connector 2 enters the interior of the FFC cable connector 1, and at the same time, the outer ring 4 also enters with the FFC cable connector 2. At this time, the limit column 10 inside the outer ring 4 gradually slides into the interior of the FFC cable connector 1 along the path of the vertical slide groove 5 after aligning with the vertical slide groove 5. During the sliding process of the limit column 10, the vertical slide groove 5 provides it with a precise guiding effect to ensure that the insertion process is smooth and there is no jamming. When one end of the FFC cable connector 2 is fully inserted into the FFC cable connector 1, the preliminary connection operation is completed.
[0047] To further ensure the firmness of the connection between the FFC cable connector 2 and the FFC cable connector 1, the operator needs to complete the locking operation by holding the handle 14 on the outer wall of the outer ring 4 and rotating the outer ring 4. While the outer ring 4 rotates, the limit column 10 performs corresponding rotational movement along the annular slide groove 6 on the inner wall of the outer sleeve 3. At this time, the limit column 10 is guided by the structure of the slide cavity 9 and will gradually be pressed into the slide cavity 9 during the rotation process. At the same time, the spring 8 is also squeezed and gradually compressed in the slide cavity 9 to store elastic potential energy. When the outer ring 4 rotates to an angle of 90 degrees, the position of the limit column 10 is exactly aligned with the inner hole 7. At this time, the spring 8 releases the stored elastic potential energy in the slide cavity 9, pushing the limit column 10 to quickly enter the inner hole 7. After the limit column 10 enters the inner hole 7, the final fixation of the FFC cable connector 2 and the FFC cable connector 1 is completed, ensuring that the connection between the two is firm and stable. Since the spring 8 continuously provides thrust for the limiting column 10, the limiting column 10 always remains in the inner hole 7 when the external force is not released, thereby effectively preventing the FFC cable connector 2 2 and the FFC cable connector 1 from accidentally falling off.
[0048] The entire connection process is ingeniously designed, with the coordination of various structures such as the initial positioning of the insertion rod 12 and the fixing block 13, the sliding guide of the limit column 10 and the vertical slide groove 5, and the elastic reset of the spring 8, ensuring the efficient connection of the FFC cable assembly. This working principle not only avoids biased insertion, improves connection stability, and reduces misoperation, but also significantly extends the service life of the assembly, and is suitable for high-frequency use requirements in a variety of complex scenarios.
[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
