Description

Technical Field

[0001] The utility model relates to the technical field of FFC connecting wires, and specifically relates to an FFC connecting wire for high-frequency signal transmission. Background Technique

[0002] The FFC connecting wire, also known as a flexible flat cable, can arbitrarily select the number of wires and the spacing, making the connection more convenient, greatly reducing the volume of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as a data transmission cable between moving parts and the main board, between PCB boards, and in miniaturized electrical equipment. Currently, it is widely used in the connection between the print head of various printers and the main board, and in the signal transmission and board-to-board connection of products such as plotters, scanners, copiers, speakers, liquid crystal appliances, fax machines, and various DVD players.

[0003] At present, the FFC connecting wire is easily interfered with by external factors in the signal transmission of this wire arrangement, and it cannot maintain the strongest transmission signal and the fastest transmission speed under any circumstances. Moreover, due to the relatively thin FFC connecting wire, during the use process, once it comes into contact with a hard object, it is easy to cause damage to the outer covering layer of the FFC connecting wire, thereby affecting the use of the FFC connecting wire. After being damaged, it is generally directly replaced forcefully, resulting in waste of materials and high costs. Content of the Utility Model

The protective member 2 is sleeved on the wire body 1. Plug connectors 101 are integrally provided at both ends of the wire body 1, facilitating the stable connection of the wire body 1 to the usage part for stable use. Moreover, the upper shell 201 and the lower shell 202 of the protective member 2 are spliced and combined to form an outer shell, forming a stable wrapping shell to wrap and protect the damaged part on the wire body 1, ensuring the stable use of the wire body 1. Sealing strips 203 are arranged on both the upper shell 201 and the lower shell 202. The sealing strips 203 tightly abut against the wrapping layer outside the wire body 1, facilitating the sealing of the gap at the connection part to achieve stable sealed connection. And anti-slip members 204 are arranged on the inner walls of both the upper shell 201 and the lower shell 202. The anti-slip members 204 abut against the wire body 1, enhancing the stability of the combined shell installed on the wire body 1 and providing stable and effective protection for the damaged part of the wire body 1.

[0021] As Figure 1 and Figure 2 shown, in some embodiments, the buckle 2021 integrally provided on the lower shell 202 is buckled into the buckle groove 2011 opened at the corresponding part on the upper shell 201. The buckle groove 2011 and the buckle 2021 are arranged in one-to-one correspondence and cooperation, facilitating the stable connection of the upper shell 201 and the lower shell 202 together by using their cooperation to form a stable wrapping shell to wrap and protect the damaged part on the wire body 1, ensuring the stable use of the wire body 1. An installation groove 2022 for installing the sealing strip 203 is opened on the lower shell 202. The sealing strip 203 is fixedly embedded in the installation groove 2022, facilitating the stable installation of the sealing strip 203 on the lower shell 202, enabling them to be stably combined and used together to seal the gap at the connection part between the lower shell 202, the wire body 1, and the upper shell 201, preventing dust and external sundries from entering the interior of the combined shell and ensuring stable use;

[0022] A groove body matching with the sealing strip 203 is provided at the position where the sealing strip 203 is placed on the upper shell 201, so that the sealing strip 203 can be stably installed on the upper shell 201, so that the two can be stably used together, and the gap at the connection between the upper shell 201 and the wire body 1 and the lower shell 202 is blocked to prevent dust and foreign objects from entering the interior of the combined shell, thereby ensuring stable use. The contact position between the sealing strip 203 and the wire body 1 and the position where they conflict with each other are provided with deformable outer protrusions, and a deformable inner cavity is provided in the outer protrusion, so that when the sealing strip 203 conflicts with the contact object, it can produce appropriate deformation, increase the contact area, and achieve a stable and effective sealing connection.

[0023] like Figure 2 and Figure 3 As shown, in some embodiments, the placement plate 2041 of the anti-slip member 204 is fixedly embedded in the embedding groove 2023 opened at the corresponding position on the lower shell 202 and the sink groove opened at the corresponding position on the upper shell 201, so that the anti-slip member 204 can be stably installed on the upper shell 201 and the lower shell 202, so that they can be stably matched with each other for use, so that the shell formed by the combination of the two can be stably placed on the line body 1, and the damaged part on the line body 1 can be stably and effectively wrapped for protection, without replacing a new FFC connecting line Under such circumstances, it is ensured that the existing damaged wire body 1 can continue to be used stably, and the convenience and cost of inspection and maintenance are improved. A soft arc plate 2042 is fixedly connected to the side of the placement plate 2041 facing the wire body 1, and a contact foot plate 2043 is integrally provided at the end of the soft arc plate 2042. By using the cooperation of the soft arc plate 2042 and the contact foot plate 2043, the anti-slip member 204 is stably contacted to the wire body 1, so that the upper shell 201 and the lower shell 202 can be fixed and limited at the damaged position on the wire body 1, so as to achieve the purpose of stable use;

[0024] The side of the abutting foot plate 2043 in contact with the wire body 1 is provided with evenly distributed anti-skid protrusions 2044, which is convenient for increasing the friction between the abutting foot plate 2043 and the surface of the wire body 1, ensuring that the anti-skid part 204 can stably and effectively limit and fix the wire body 1, and the inner side of the bending part of the soft arc plate 2042 is provided with deformation notches 2045 distributed at equal intervals, which is convenient for the soft arc plate 2042 to deform when it is subjected to force, so that the entire soft arc plate 2042 produces corresponding deformation, tightly abuts in the gap between the inner wall of the shell and the wire body 1, thereby improving the efficiency of limiting and fixing.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features.
