Description

Technical Field

[0001] This utility model belongs to the field of flexible flat cable technology, and particularly relates to a tensile-resistant flexible flat cable. Background Technology

[0002] Flexible flat cables are devices used for signal transmission. These cables allow for flexible selection of the number and spacing of wires, making wiring easier, significantly reducing the size of electronic products, lowering production costs, and improving production efficiency. They are ideally suited for data transmission cables between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment.

[0003] During the use of flexible flat cables, when the cable is subjected to excessive tensile force, the copper conductor of the cable may partially break or be stretched and thinned. This change will increase the resistance of the conductor, leading to increased conductor heating and accelerating the aging process of the cable. Furthermore, excessive stretching will cause the cable insulation layer to become thinner, crack, or separate from the conductor. Once the insulation layer cracks, impurities such as moisture and dust can easily penetrate, causing leakage and potentially further corroding the conductor.

[0004] Therefore, it is necessary to improve the existing flexible flat cables. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a tensile-resistant flexible flat cable, which improves the strength of the flexible flat cable.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a tensile-resistant flexible flat cable is as follows:

[0007] A tensile-resistant flexible flat cable, comprising:

[0008] Line body;

[0009] End caps are provided at both ends of the line body;

[0010] Multiple support rings are sleeved on the outer periphery of the line body and are spaced apart along the extension direction of the line body;

[0011] Multiple hinged rods are hinged between the adjacent end cap and the support ring, as well as between two adjacent support rings.

[0012] Preferably, in order to extend the service life of the cable, the cable body includes a protective layer and a plurality of wire cores arranged side by side, the protective layer enclosing each of the wire cores, and an insulation layer is provided on the outer periphery of each of the wire cores.

[0013] Preferably, in order to reduce cable wear and extend cable service life, a lubricating layer is provided on the outer surface of the protective layer, and the lubricating layer is a polytetrafluoroethylene layer.

[0014] Preferably, in order to reduce the probability of the wire core breaking due to excessive bending, the end cap is interference-fitted with the end of the wire body, and the bottom of the end cap is provided with a wire hole for passing the wire core through, and an elastic support sleeve is coaxially fixedly connected to the wire hole.

[0015] Preferably, in order to reduce the temperature of the cable and slow down the aging of the cable, the protective layer has multiple ventilation holes inside along its own extension direction, and the ventilation holes are arranged alternately and side by side with the wire core.

[0016] Preferably, in order to improve the heat dissipation effect of the cable, the sidewall of the ventilation hole is provided with a plurality of ventilation slots that connect to the outside of the protective layer, and each ventilation slot is equally spaced along the extension direction of the ventilation hole.

[0017] Preferably, in order to ensure the ventilation effect of the ventilation hole and reduce the working temperature of the cable, the bottom of the end cap is provided with an opening that communicates with the ventilation hole.

[0018] Preferably, in order to achieve the rotational connection between the end cap and the support ring and the hinge rod, the width direction of the line body is the first direction, and the support ring and the end cap are fixedly connected to both sides of the first direction. The two hinge shafts are coaxially arranged along the first direction, and the end of the hinge rod is provided with a hinge hole for the hinge shaft to pass through.

[0020] The tensile-resistant flexible flat cable of this utility model has the following advantages: the end cap, support ring and hinge rod are combined to form a hollow shell that can bend synchronously with the cable.

[0030] like Figure 1 As shown, a tensile-resistant flexible flat cable includes:

[0031] Line 1;

[0032] End caps 3 are located at both ends of line body 1;

[0033] Multiple support rings 2 are sleeved on the outer periphery of the line body 1 and are distributed at intervals along the extension direction of the line body 1;

[0034] Multiple hinge rods 4 are hinged together between adjacent end caps 3 and support rings 2, as well as between two adjacent support rings 2.

[0035] In the aforementioned flexible flat cable, both ends of the cable body 1 are inserted into the interiors of two end caps 3, which protect the ends of the cable body 1. When the cable body 1 is subjected to impact or compression, the support rings 2 fitted around the outer periphery of the cable body 1 can protect the cable body 1 and prevent damage during impact or compression. The two end caps 3 and each support ring 2 located at both ends of the cable body 1 are interconnected by hinge rods 4. The hinge rods 4 can withstand the tensile force on the cable body 1, thereby reducing the tensile force on the cable body 1 and lowering the probability of damage. Hinges 4 are provided on both sides along the width direction of the cable body 1. By having the hinge rods 4 on both sides simultaneously withstand the tensile force, the tensile force resistance of the cable body 1 can be improved. The hinge rods 4 are rotatably connected to the end caps 4 and the support rings 2, so that the overall structure formed by the support rings 2, hinge rods 4 and end caps 3 can bend synchronously with the bending of the cable body 1, thereby better protecting the cable body 1.

[0036] Further improvements include, for example Figure 2 and 3 As shown, the cable body 1 includes a protective layer 103 and multiple parallel-arranged conductors 101. The protective layer 103 encloses each conductor 101, and an insulation layer 102 is provided on the outer periphery of each conductor 101. The insulation layer 102 is made of polyvinyl chloride (PVC), which has good mechanical properties, is tough and wear-resistant, and can withstand a certain degree of tension, bending and friction, making it less prone to damage during installation and use. The protective layer 103 is made of neoprene rubber, which has good oil resistance, solvent resistance and chemical corrosion resistance, strong resistance to various oils and organic solvents, high mechanical strength, good elasticity, and excellent wear resistance, and can withstand greater external forces and friction. The insulation layer 102 and the protective layer 103 protect the conductor conductors 101, thereby extending the service life of the cable.

[0037] Further improvements include, for example Figure 3 As shown, a lubricating layer 104 is provided on the outer surface of the protective layer 103. The lubricating layer 104 is a polytetrafluoroethylene (PTFE) layer. PTFE has an extremely low coefficient of friction, thereby reducing the friction between the cable body 1 and the support ring 2 through the lubricating layer 104, thus reducing mutual wear and extending the service life of the cable.

[0038] Further improvements include, for example Figure 4As shown, the end cap 3 is interference-fitted with the end of the cable body 1. The bottom of the end cap 3 has a through-hole for threading the wire core 101. A flexible support sleeve 302 is coaxially fixedly connected to the through-hole. The end cap 3 can be made of metal. By squeezing the end cap 3 with pliers, it is deformed, thus tightly bonding with the cable body 1. The end cap 3 effectively protects the end of the cable body 1. During wiring, the protective layer 103 on the outside of the wire core 101 needs to be peeled off, allowing the wire core 101 with the insulation layer 102 to pass through the support sleeve 302. The support sleeve 302 protects the wire core 101, and its elasticity supports the wire core 101, preventing excessive bending and reducing the likelihood of breakage, thus extending the cable's lifespan.

[0039] Further improvements include, for example Figure 2 and 3 As shown, the protective layer 103 has multiple ventilation holes 105 extending along its own direction, and the ventilation holes 105 are arranged alternately with the wire cores 101. The ventilation holes 105 allow air to circulate inside the protective layer 103, thereby carrying away the heat generated by the wire cores 101 during operation, thus slowing down the high-temperature aging of the cable and extending its service life. The alternating arrangement of the ventilation holes 105 and the wire cores 101 can improve the uniformity of heat dissipation to the wire cores 101 and enhance the heat dissipation effect of the cable. At the same time, the ventilation holes 105 can also reduce the overall weight of the cable.

[0040] Further improvements include, for example Figure 2 and 3 As shown, the sidewall of the ventilation hole 105 is provided with multiple ventilation grooves 106 that connect to the outside of the protective layer 103. Each ventilation groove 106 is evenly distributed along the extension direction of the ventilation hole 105. During the bending of the cable, the ventilation hole 105 is prone to blockage. At this time, the ventilation grooves 106 can be used to achieve air circulation between the inside and outside of the ventilation hole 105, thereby ensuring the ventilation effect of the cable. When using flat cables, the required number of cable cores 101 varies. When there are too many cores 101, the protective layer 103 can be torn open along each ventilation groove 106 to separate the cores 101 from the cable and retain the required number of cores 101, improving the convenience of cable use.

[0041] Further improvements include, for example Figure 4 As shown, the bottom of the end cap 3 has an opening 303 that connects to the ventilation hole 105. The opening 303 is provided to prevent the end cap 3 from blocking the ventilation hole 105, so as to maintain the heat dissipation effect of the cable.

[0042] Further improvements include, for example Figure 4 and 5As shown, along the width direction of the cable body 1, which is the first direction, the support ring 2 and the end cap 3 are both fixedly connected to hinge shafts 301 on both sides of the first direction. The two hinge shafts 301 are coaxially arranged along the first direction. The end of the hinge rod 4 is provided with a hinge hole for the hinge shaft 301 to pass through. The hinge hole is connected to the hinge shaft 301, realizing the rotational connection between the hinge rod 4 and the support ring 2 and the end cap 3. This allows the overall structure formed by the end cap 3, the support tube 2, and the hinge rod 4 to bend with the cable, improving the flexibility of the cable during use.

[0043] Further improvements include, for example Figure 6 As shown, the hinge shaft 301 has a threaded hole coaxially connected to a bolt 5. The bolt 5 enables the disassembly of the hinge shaft 301 from the support ring 2 and the end cap 3, improving the convenience of cable maintenance.
