Description

Technical Field

[0001] This utility model relates to the field of USB connector technology, and in particular to a USB connector with one plug and one solder at the FFC end. Background Technology

[0002] USB cables, often simply referred to as USB cables, are widely used computer interface cables used to connect various electronic devices to achieve functions such as data transmission, backup, synchronization, and device charging.

[0003] FFC stands for Flexible Fiber Optic Cable, and a USB cable with one plug and one solder joint at the FFC end is a special type of cable. Its characteristic is that one end of the FFC connector uses a plug-in connection, while the other end uses a solder joint. This type of cable is typically used to connect to a USB interface. However, when not in use, the plug of existing one-plug-one-solder USB cables is prone to getting dust, moisture, and other impurities inside, leading to problems such as poor connection and reduced data transfer speeds later on. Furthermore, the durability of one-plug-one-solder USB cables needs improvement. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an FFC-type USB connector with one plug and one solder joint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an FFC-type USB connector cable with one plug and one solder joint, including a cable body with a protective mechanism installed on it. The cable body includes a conductor layer, an insulation layer fixedly installed on the conductor layer, an inner sheath fixedly installed on the insulation layer, a filler layer fixedly installed on the inner sheath, a shielding layer fixedly installed on the filler layer, an armor layer fixedly installed on the shielding layer, a first reinforcing layer fixedly installed on the armor layer, a second reinforcing layer fixedly installed on the first reinforcing layer, and an outer sheath fixedly installed on the second reinforcing layer.

[0007] Furthermore, a plug is fixedly installed at one end of the wire, and a soldering end is fixedly installed at the other end of the wire.

[0008] Furthermore, the protective mechanism includes a sleeve, which is fixedly installed on the line. The sleeve is circular in shape, and two elastic bands are fixedly installed on the sleeve. One end of each elastic band is fixedly fitted with the same insert.

[0009] Furthermore, the insulating layer is made of polytetrafluoroethylene, and the inner sheath is made of PVC.

[0010] Furthermore, the filling layer is made of foamed polyethylene, and the shielding layer is made of copper wire.

[0011] Furthermore, the armor layer is made of copper wire, and the first reinforcing layer is made of aramid fiber.

[0012] Furthermore, the second reinforcing layer is made of nylon, and the outer protective layer is made of polyurethane.

[0013] This utility model proposes an FFC-terminal plug-in / solderable USB connector cable, which has the following advantages: The connector features a protective mechanism to protect the plug when not in use, facilitating future use; an insulation layer isolates the current in the internal conductors, preventing short circuits and providing a stable signal transmission environment; an inner sheath protects the internal structure; and a filler layer provides additional support and protection, preventing damage or deformation of the internal conductors due to external pulling. It has a shielding layer to avoid the impact of external electromagnetic interference on data transmission, and also to prevent signal leakage inside the cable from interfering with other devices. The armor layer enhances the tensile strength, impact resistance and protection of the connector, improving its durability in harsh environments. The first reinforcing layer enhances the tensile strength of the connector, preventing the cable from breaking or being damaged due to frequent pulling or bending. The second reinforcing layer further improves the tensile performance of the connector. The outer sheath provides overall external protection, preventing physical damage, friction, tension and other factors from damaging the internal structure. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A USB connector cable with an FFC-type plug-in and solder joint, comprising a cable body 1, characterized in that: a protective mechanism is installed on the cable body 1, which protects the plug 3 when it is not in use, facilitating subsequent use of the USB connector cable; the cable body 1 includes a conductor layer 11, on which an insulation layer 12 is fixedly installed, which isolates the current of the internal conductors, prevents short circuits, and provides a stable transmission environment for signals; an inner sheath 13 is fixedly installed on the insulation layer 12, which provides protection for the internal structure; a filler layer 14 is fixedly installed on the inner sheath 13, which provides additional support and protection for the cable, preventing damage or deformation of the internal conductors of the cable body 1 due to external pulling; and a shielding layer 15 is fixedly installed on the filler layer 14. The cable is equipped with a shielding layer 15 to prevent external electromagnetic interference from affecting data transmission and to prevent signal leakage from the cable from interfering with other devices. An armor layer 16 is fixedly installed on the shielding layer 15 to enhance the tensile strength, impact resistance, and protective capabilities of the cable, thereby improving its durability in harsh environments. A first reinforcing layer 17 is fixedly installed on the armoring layer 16 to enhance the tensile strength of the cable and prevent breakage or damage caused by frequent pulling or bending. A second reinforcing layer 18 is fixedly installed on the first reinforcing layer 17 to further improve the tensile performance of the cable. An outer sheath 19 is fixedly installed on the second reinforcing layer 18 to provide overall external protection and prevent damage to the internal structure caused by physical damage, friction, tension, and other factors.

[0020] In detail, a plug 3 is fixedly installed at one end of the cable body 1, which is used to insert into the connector, and a soldering end 4 is fixedly installed at the other end of the cable body 1, which is used to solder to electronic equipment or circuit boards.

[0021] Furthermore, the protective mechanism includes a sleeve 21, which is fixedly installed on the line 1. The sleeve 21 is circular in shape and is designed to support the installation of the elastic band 23. Two elastic bands 23 are fixedly installed on the sleeve 21. The elastic bands 23 are designed to support the installation of the plug sleeve 22 and also provide force for the plug sleeve 22 so that it can be inserted into the plug 3. One end of each of the two elastic bands 23 is fixedly installed with the same plug sleeve 22. The plug sleeve 22 is designed to protect the plug 3.

[0022] Furthermore, the insulating layer 12 is made of polytetrafluoroethylene (PTFE), also known as Teflon, commonly called "the king of plastics." PTFE is a high-molecular polymer polymerized from tetrafluoroethylene monomers. PTFE has excellent electrical insulation properties and is one of the best known electrical insulation materials. The insulating layer 12 is used to isolate the current in the internal conductors, prevent short circuits, and provide a stable transmission environment for signals. The inner sheath 13 is made of PVC, a widely used thermoplastic. Its chemical structure is formed by the polymerization of vinyl chloride monomers. Due to its good chemical stability, durability, plasticity, and economy, PVC has become one of the important materials in many industries. The inner sheath 13 is used to provide protection for the internal structure.

[0023] More specifically, the filler layer 14 is made of foamed polyethylene, a lightweight, soft, and elastic plastic material manufactured from polyethylene through a physical foaming process. Its structure contains numerous tiny air bubbles, giving it excellent cushioning, heat insulation, shock resistance, thermal insulation, and sound insulation properties. The filler layer 14 provides additional support and protection for the cable, preventing damage or deformation of the conductors inside the cable body 1 due to external pulling forces. The shielding layer 15 is made of copper wire. The shielding layer 15 prevents external electromagnetic interference from affecting data transmission and also prevents signal leakage inside the cable from interfering with other devices.

[0024] In summary, the armor layer 16 is made of copper wire. By incorporating the armor layer 16, the tensile strength, impact resistance, and protective capabilities of the connecting cable are enhanced, improving its durability in harsh environments. The first reinforcing layer 17 is made of aramid fiber, a synthetic fiber with an aromatic chemical structure, primarily composed of polyamide compounds. Due to its excellent strength, heat resistance, chemical resistance, and abrasion resistance, aramid fiber is widely used in high-performance applications. The first reinforcing layer 17 enhances the tensile strength of the connecting cable, preventing cable breakage or damage due to frequent pulling or bending.

[0025] Finally, the second reinforcing layer 18 is made of nylon. The second reinforcing layer 18 is used to further improve the tensile strength of the connecting wire. The outer sheath 19 is made of polyurethane. The outer sheath 19 is used to provide overall external protection and prevent physical damage, friction, tension and other factors from damaging the internal structure.

[0026] Operating mode: During operation, the insulation layer 12 isolates the current in the internal conductors to prevent short circuits and provides a stable signal transmission environment. The inner sheath 13 protects the internal structure. The filler layer 14 provides additional support and protection for the cable, preventing damage or deformation of the internal conductors due to external pulling. The shielding layer 15 prevents external electromagnetic interference from affecting data transmission and also prevents signal leakage from the cable from interfering with other devices. The armor layer 16 enhances the tensile strength, impact resistance, and protective capabilities of the connecting cable, improving its durability in harsh environments. The first reinforcing layer 17 enhances the tensile strength of the connecting cable, preventing breakage or damage due to frequent pulling or bending. The second reinforcing layer 18 further improves the tensile performance of the connecting cable. The outer sheath 19 provides overall external protection, preventing damage to the internal structure from physical damage, friction, tension, and other factors.

[0027] When the one-plug-one-solder USB cable is not in use, the sleeve 23 can be plugged into the plug 3 to protect the plug 3 and facilitate the subsequent use of the one-plug-one-solder USB cable.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
