Drawings
Fig. 1 is a schematic structural diagram of a vehicle-mounted easy-to-detach gigabit ethernet cable according to an embodiment of the present invention.
Detailed Description
To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
For the requirement that improves current ethernet, signal core conductor need adopt the high strength tin copper alloy conductor, and insulating adoption can satisfy the insulating material of high temperature and high humidity environment, and the signal heart yearn pair twist needs to adopt pair twist to drag the package integrative, and temperature resistant, resistant oil, fire-retardant environmental protection material are chooseed for use to insulating outer. Moreover, with the automated processing, the processing of the required wire rod has to be a major focus of the product.
In one embodiment, referring to fig. 1, a vehicle-mounted easy-to-peel ethernet cable includes: a pair assembly 10 and an insulating outer cover 20, wherein the pair assembly 10 is used for transmitting signals or data; the insulating outer cover 20 is used for protecting the wire pair assembly, and the service life is prolonged.
Referring to fig. 1, the pair assembly 10 includes two core wires 11 twisted with each other and a polyester tape 12 covering the two core wires, each of the core wires includes 7 conductors 11a and an insulating layer 11b covering the conductors 11 a; the insulating coating is coated on the polyester tape. In this embodiment, the conductor is a hard tin-copper alloy conductor, and the diameter of the conductor is 0.154 mm. 7 conductors are twisted with each other. The 7 hard tin-copper alloy conductors with the thickness of 0.154mm not only can stably transmit signals, but also can greatly improve the tensile capacity among wires and the wires and terminals.
It should be noted that the pitch length of the twisted conductors is in a multiple relation to the diameter length of the conductors. Further, the pitch length of the conductor is equal to 12 times the diameter length of the conductor. The 7 regular twists and the 12-fold pitch-diameter ratio have a more round and stable structure, and better concentricity can be achieved after insulation is extruded, so that signal transmission is more stable.
In this embodiment, the insulating layer is made of a polypropylene material with high flame retardancy. The modified polypropylene is adopted, and not only has the ultralow dielectric constant of pure polypropylene, but also has higher temperature resistance and excellent flame retardant property; 2.2, the dielectric constant can ensure that the wire can be made into a smaller wire diameter while meeting the signal transmission requirement, so that the wiring space of the whole vehicle is saved; the temperature after modification is increased, so that the wire can work stably for a long time at the high temperature of 125 ℃; the high flame retardance of the high-flame-retardant high-safety flame-retardant high-safety flame-retardant wire rod ensures that the application of the wire rod has higher safety characteristics. Therefore, the modified polypropylene is adopted, so that the wire rod has stable signal transmission, the performances of temperature resistance, flame retardance and the like of the wire rod are greatly improved, and the wire rod can still stably transmit signals in a severe environment.
The polyester tapes are self-adhesive polyester tapes, and are wrapped on the two core wires in a tightly attached and twisted-pair bale pulling manner. In order to ensure the stability of the twisted pair structure and distinguish from the traditional wrapping, a dragging mode of tightly fitting the twisted pair is adopted; in addition, in order to ensure that the client processing avoids manually cutting off redundant wrapping tapes, the self-adhesive polyester tape and the self-adhesive layer are outwards adopted, when the self-adhesive polyester tape is extruded, the self-adhesive layer of the polyester tape is melted through high temperature during extrusion, the polyester tape is tightly attached to the outer quilt, and when the client processing is peeled, the outer quilt and the polyester tape can be once opened, so that repeated processing is avoided. Therefore, the polyester belt bale enables the pair twisting structure to be more stable, and prevents the adhesion of the outer covering material and the insulating core wire when the outer covering is extruded; the tow bag is tighter, the air in the middle of the pair twisting group is reduced, and the stability of signal transmission is better. The polyester tape is outwards adhered to the self-adhesive layer, is melted by the temperature of the outer cover and is tightly attached to the outer cover, so that the stability of signal transmission is guaranteed, a client can complete the peeling process once when the outer cover is processed, and secondary working time waste is avoided.
The insulating coating is a high-temperature-resistant thermoplastic insulating coating. The outer layer is made of 125 ℃ modified thermoplastic elastomer, so that the wire has very good chemical resistance, high temperature resistance, corrosion resistance, wear resistance, low-temperature flexibility and the like, and the service life of the wire in the severe environment of an automobile can be more than 15 years; in addition, the dielectric constant of the cable is more stable, and the stability of signal transmission of the core wire is improved while the insulating core wire is protected. So, the insulating outer quilt adopts a 125 ℃ modified high temperature resistant thermoplastic elastomer, can guarantee that the wire rod still can stabilize normal work under the 125 ℃ condition, and the protection heart yearn is stable transmission signal more than 15 years under the comparatively abominable environment of car simultaneously, and this application has and stable dielectric constant in addition, gives as security out the back, and whole wire rod has very high electric uniformity, not only can protect the heart yearn, has still guaranteed that the wire rod still possesses stable signal transmission function when the big length is used.
The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
