Description

Technical Field

[0001] This utility model relates to the field of electronic connection wire technology, and in particular to an electronic connection wire with extended service life. Background Technology

[0002] Electronic connection cables are components used to connect electrical circuits. Their primary function is to provide electrical connections and signal transmission between devices and components, components and cabinets, and systems and subsystems. They also ensure that there is no signal distortion or energy loss between systems. Their quality directly affects the overall reliability of the system equipment and are an important supporting product for OEMs. Their technical characteristics are greatly influenced by the technological development of downstream industries. In the operation of construction machinery, electronic connection cables are also frequently used to connect to external auxiliary equipment (such as remote controls). An electronic connection cable consists of, from the inside out, a tinned copper core, a shielding layer, a tensile layer, and a rubber layer wrapped around the tensile layer.

[0003] Regarding the aforementioned technologies, the inventors discovered that electronic connecting wires used in engineering machinery are prone to breakage due to pulling. Existing electronic connecting wires have a certain static friction between their tensile layer and rubber layer. When the electronic connecting wire is subjected to external pulling, and the pulling force exceeds the static friction between the tensile layer and the rubber layer, the pulling force acts on the rubber layer, causing it to easily break due to the large pulling force. This reduces the protection of the tin-plated copper core and shortens its service life. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an electronic connecting wire with extended service life. By embedding the raised part on the braided tensile tube into the inner surface of the rubber tube layer, the two are cross-connected in the radial direction to form an integral structure, which enhances the tensile strength of the connecting wire body and extends its service life.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an electronic connecting wire with extended service life, comprising: a connecting wire body, wherein the area of ​​the connecting wire body near the end is a spiral structure, and the two ends of the connecting wire body are respectively connected to connecting terminals;

[0006] The connecting wire body includes a shielding tube and several tin-plated copper cores disposed in its holes. The outer circular surface of the shielding tube is recessed along its length direction to provide a receiving cavity. A ground wire is disposed in the receiving cavity. A braided tensile tube is sleeved on the outer surface of the shielding tube. The outer surface of the braided tensile tube is wrapped with a rubber tube layer.

[0007] The braided tensile tube body includes a braided tube and a textured portion connected to its outer surface, the textured portion being embedded in the inner surface of the rubber tube layer.

[0008] By adopting the above technical solution, during use, the connector at one end of the connector body connects to the engineering machinery, and the connector at the other end connects to external auxiliary equipment, allowing the connector body to transmit signals. Because the areas near the ends of the connector body are spiral structures, when the electronic connector is pulled quickly, the spiral structure of the connector body first unfolds, extending its length, reducing damage to the electronic connector and extending its service life. The use of a shielding tube reduces the influence of the external environment on the signal transmission of the tinned copper core. The ground wire installed inside the cavity helps maintain the potential stability between different parts of the circuit, ensuring normal circuit operation. The convex part on the outer surface of the braided tube is embedded in the inner surface of the rubber tube layer, allowing the two to cross-connect in the radial direction to form an integral structure, enhancing the tensile strength of the connector body and extending its service life.

[0009] In a preferred embodiment, the present invention can be further configured such that the textured portion includes a plurality of annular bodies woven at intervals on the outer surface of the braided tube, the annular bodies being embedded in the inner surface of the rubber tube layer.

[0010] By adopting the above technical solution, since the annular body and the braided tube are connected by braiding, and the annular body is embedded in the inner surface of the rubber tube layer, the rubber tube layer and the braided tube form an integral structure, which enhances the tensile strength of the electronic connection wire.

[0011] In a preferred embodiment, the present invention can be further configured such that the textured portion includes a plurality of spirally woven threads on the outer circular surface of the braided tube, the spiral threads being embedded in the inner surface of the rubber tube layer.

[0012] By adopting the above technical solution, since the threaded wire and the braided tube are connected by braiding, and the threaded wire is embedded in the inner surface of the rubber tube layer, the rubber tube layer and the braided tube form an integral structure, which enhances the tensile strength of the electronic connection wire.

[0013] In a preferred embodiment, the present invention can be further configured such that: a wear-resistant spiral body is connected to the outer circular surface of the rubber tube layer, and the wear-resistant spiral body is made of wear-resistant rubber.

[0014] By adopting the above technical solution, when the electronic connection line moves, the wear-resistant spiral body reduces the probability of friction between the rubber tube layer and external objects, thus reducing the wear on the rubber tube layer.

[0015] In a preferred embodiment, the present invention can be further configured such that the shielding tube body is made of aluminum foil.

[0016] By adopting the above technical solution, aluminum foil has a certain degree of flexibility and shielding function, which enhances the convenience of processing and improves the performance of electronic connection wires.

[0017] In a preferred embodiment, the present invention can be further configured such that the braided tube is woven from several glass fiber flat strips.

[0018] By adopting the above technical solution, the glass fiber material has high tensile strength, and the braided tube is formed by weaving several glass fiber flat strips, which makes the braided tube have good tensile properties in both the radial and length directions, thus enhancing the performance.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. By embedding the convex part of the outer surface of the braided tube into the inner surface of the rubber tube layer, the two are cross-connected in the radial direction to form an integral structure, which enhances the tensile strength of the connecting wire body and extends its service life.

[0021] 2. Because the area near the end of the connecting wire body has a spiral structure, when the electronic connecting wire is pulled quickly, the spiral structure of the connecting wire body first unfolds and extends its own length, reducing the damage to the electronic connecting wire caused by pulling and extending its service life.

[0022] 3. When the electronic connection wire moves, the wear-resistant spiral reduces the probability of friction between the rubber tube layer and external objects, thus reducing the wear on the rubber tube layer. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Example 1:

[0035] Reference Figures 1-3 The present invention discloses an electronic connecting wire with extended service life, comprising: a connecting wire body 10, wherein the area near the end of the connecting wire body 10 is a spiral structure, and the two ends of the connecting wire body 10 are respectively connected to connecting terminals 2.

[0036] The connecting cable body 10 includes a shielding tube 11 and several tin-plated copper cores 12 disposed in its holes. The outer circular surface of the shielding tube 11 is recessed along its length to provide a receiving cavity 13. A ground wire 14 is disposed in the receiving cavity 13. A braided tensile tube 15 is sleeved on the outer surface of the shielding tube 11. The outer surface of the braided tensile tube 15 is wrapped with a rubber tube layer 16. The rubber tube layer 16 has the function of protecting the tin-plated copper cores 12 and reducing the damage of corrosive gases or liquids to the tin-plated copper cores 12.

[0037] The braided tensile tube 15 includes a braided tube 151 and a textured portion 152 connected to its outer surface, the textured portion 152 being embedded in the inner surface of the rubber tube layer 16.

[0038] The textured portion 152 includes a plurality of annular bodies 1521 woven at intervals on the outer surface of the braided tube 151. The annular bodies 1521 are embedded in the inner surface of the rubber tube layer 16. Since the annular bodies 1521 and the braided tube 151 are connected by braiding, and the annular bodies 1521 are embedded in the inner surface of the rubber tube layer 16, the rubber tube layer 16 and the braided tube 151 form an integral structure, which enhances the tensile strength of the electronic connection wire.

[0039] The outer surface of the rubber tube layer 16 is connected to a wear-resistant spiral 3, which is made of wear-resistant rubber. Through the action of the wear-resistant spiral 3, the probability of friction between the rubber tube layer 16 and external objects is reduced, that is, the wear of the rubber tube layer 16 is reduced.

[0040] The shielding tube body 11 is made of aluminum foil; the aluminum foil has a certain degree of flexibility and shielding function, which enhances the convenience of processing and improves the performance of electronic connection wires.

[0041] The braided tube 151 is made of several glass fiber flat strips woven together. Glass fiber has high tensile strength, and the braided tube 151 is formed by weaving several glass fiber flat strips, which makes the braided tube 151 have good tensile properties in both the radial and length directions, thus enhancing its performance.

[0042] The implementation principle of this embodiment 1 is as follows: In use, the connecting terminal 2 at one end of the connecting wire body 10 is connected to the engineering machinery, and the connecting terminal 2 at the other end is connected to the external auxiliary equipment. The connecting wire body 10 can transmit signals. Since the area near the end of the connecting wire body 10 is a spiral structure, when the electronic connecting wire is pulled quickly, the spiral structure of the connecting wire body 10 first unfolds and extends its own length, reducing the damage to the electronic connecting wire caused by pulling and extending its service life. Through the use of the shielding tube 11, the influence of the external environment on the signal transmission of the tinned copper core 12 is reduced. Through the ground wire 14 set in the receiving cavity 13, the ground wire 14 helps to maintain the potential stability between the parts in the circuit and ensure the normal operation of the circuit. Through the convex part 152 on the outer surface of the braided tube 151 embedded in the inner surface of the rubber tube layer 16, the two are cross-connected in the radial direction to form an integral structure, which enhances the tensile strength of the connecting wire body 10 and extends its service life.

[0043] Example 2:

[0044] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the textured part 152 includes a plurality of spirally woven thread bodies 1522 on the outer circular surface of the braided tube 151, and the thread bodies 1522 are embedded in the inner surface of the rubber tube layer 16.

[0045] The implementation principle of this embodiment 2 is as follows: Since the threaded wire 1522 and the braided tube 151 are connected by braiding, the threaded wire 1522 is embedded in the inner surface of the rubber tube layer 16, which expands the indirect connection area between the rubber tube layer 16 and the braided tube 151, so that the rubber tube layer 16 and the braided tube 151 form an integral structure, which enhances the tensile strength of the electronic connection wire.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
