[0018] This invention provides a first protective sleeve on the outer surface of the electronic wire harness to prevent damage when the wire harness is exposed. The electronic wire harness is bent within a first wire groove to form a first bend. When the electronic wire harness is pulled, the wire harness at the first bend is pulled first, protecting the connection between the electronic wire harness and the plug from tension. A first limiting plate is provided at the end of the first protective sleeve. When the first protective sleeve is pulled and the first limiting plate reaches the end of the first protective groove, the tension and the reaction force of the first protective groove on the first limiting plate act directly on the first protective sleeve, protecting the internal electronic wire harness. The first limiting plate slides within the first protective groove, and the length of the first protective groove is no greater than the length of the electronic wire harness at the first bend.

This ensures that the connection between the electronic wire harness and the plug is protected from tension, extends service life, and makes the circuit connection more stable.

By setting a second limiting plate at the end of the second protective sleeve, the second protective sleeve is stretched. When the second limiting plate reaches the end of the second protective groove, the tensile force and the second protective groove exert force on the second limiting plate. The reaction force acts directly on the second protective sleeve to protect the internal electronic wire harness. When the first limiting plate reaches the end of the first protective groove first, the pulling force and the reaction force of the first protective groove on the first limiting plate act directly on the first protective sleeve to protect the internal electronic wire harness. While the electronic wire harness can be pulled, the first and second limiting plates limit the length that the electronic wire harness can be pulled, keeping the electronic wire harness between the first limiting plate and the first wire groove in a relaxed state. This ensures that the connection between the electronic wire harness and the plug is free from pulling force, extends the service life, and makes the circuit connection more stable.
[0020] By setting the first reset spring as the first elastic element, when the external pulling force is lost, the pulled-out electronic wire bundle can be reset under the action of the elastic restoring force of the first elastic element. At the same time, in the event of accidental pulling, the elastic restoring force of the first elastic element can provide force feedback to the puller, reminding the puller to stop pulling.
[0021] By setting a second reset spring as a second elastic element, when the external pulling force is lost, the pulled-out electronic wire bundle can be reset under the elastic restoring force of the second elastic element. At the same time, in the event of accidental pulling, the elastic restoring force of the second elastic element can provide force feedback to the puller, reminding the puller to stop pulling.

[0030] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0031] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Unless otherwise specified, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0032] Example 1:
[0033] This embodiment provides a high-strength and durable electronic wire harness, such as... Figures 1-5 As shown, the device includes a housing 17, within which a wire-receiving cavity is formed. One end of the wire-receiving cavity communicates with the outside. An electronic wire harness 4 is disposed within the wire-receiving cavity. A plug 1 is provided at one end of the housing 17. One end of the electronic wire harness 4 is disposed inside the housing 17 and electrically connected to the plug 1. The other end of the electronic wire harness 4 extends through the wire-receiving cavity and outwards through the housing 17. A first protective sleeve 3 is provided on the outer surface of the electronic wire harness 4. A first limiting plate 10 is fixedly connected to the end of the first protective sleeve 3 away from the free end of the electronic wire harness 4. The wire-receiving cavity includes a first protective groove 8 and a first wire-receiving groove. The limiting plate 10 slides within the first protective groove 8. The first limiting plate 10 and the first protective groove 8 are adapted to each other. The first limiting plate 10 is located between the free end of the electronic wire harness 4 and the first wire receiving groove. The electronic wire harness 4 between the first limiting plate 10 and the first wire receiving groove is bent within the first wire receiving groove to form a first bent portion 13. The length of the first protective groove 8 is not greater than the length of the electronic wire harness 4 in the first bent portion 13. This design can protect the electronic wire harness 4 when it is pulled, preventing the connection between the electronic wire harness 4 and the connector from breaking due to pulling, ensuring the normal operation of the circuit, and extending its service life. Lifespan; by providing a first protective sleeve 3 on the outer surface of the electronic wire harness 4, damage is prevented when the electronic wire harness 4 is exposed. The electronic wire harness 4 is bent within the first wire groove to form a first bend 13. When the electronic wire harness 4 is pulled, the first bend 13 is pulled first, protecting the connection between the electronic wire harness 4 and the plug 1 from tension. By providing a first limiting plate 10 at the end of the first protective sleeve 3, when the first protective sleeve 3 is pulled and the first limiting plate 10 reaches the end of the first protective groove, the tension and the reaction force of the first protective groove on the first limiting plate 10 are directly... The first protective sleeve 3 is used to protect the internal electronic wire harness 4. The first limiting plate 10 slides in the first protective groove 8, and the length of the first protective groove 8 is not greater than the length of the electronic wire harness 4 of the first bending part 13. This allows the electronic wire harness 4 to be pulled while improving its tensile strength. The length that the electronic wire harness 4 can be pulled is limited, keeping the electronic wire harness 4 between the first limiting plate 10 and the first wire groove in a relaxed state. This ensures that the connection between the electronic wire harness 4 and the plug 1 is not subjected to tension, extends the service life, and makes the circuit connection more stable.
[0034] In this embodiment, as Figure 2 As shown, a first elastic element is provided in the first protective groove 8. One end of the first elastic element is fixedly connected to the first limiting plate 10, and the other end of the first elastic element is fixedly connected to the end of the first protective groove 8 away from the first limiting plate 10. The first elastic element is set as a first reset spring 9. By setting the first reset spring 9 as the first elastic element, when the external pulling force is lost, the pulled-out electronic wire bundle 4 can be reset under the action of the elastic restoring force of the first elastic element. At the same time, in the case of accidental pulling, the elastic restoring force of the first elastic element can provide force feedback to the puller and remind the puller to stop pulling.
[0035] In this embodiment, as Figure 2 As shown, the end of the electronic wire harness 4 near the plug 1 is snapped into the housing 17. A positioning plate 12 is provided at the end of the electronic wire harness 4. A positioning groove 11 is provided at the end of the housing 17 near the plug 1. The positioning plate 12 is detachably disposed in the positioning groove 11. By providing a positioning plate 12 at the end of the electronic wire harness 4, the positioning plate 12 and the positioning groove 11 are used to position the electronic wire harness 4, thereby improving the stability of the connection between the electronic wire harness 4 and the plug 1.
[0036] In this embodiment, as Figure 3 As shown, the electronic wire harness 4 has a tensile steel wire core 15 inside. The cross-section of the tensile steel wire core 15 is "I" shaped. The tensile steel wire core 15 is located in the middle of the electronic wire harness 4. The electronic wire harness 4 also has two connecting wires 14 inside, which are located on both sides of the tensile steel wire core 15. By setting the tensile steel wire core 15 inside the electronic wire harness 4, the tensile strength of the electronic wire harness 4 itself is improved.
[0037] Example 2:
[0038] This embodiment provides a high-strength and durable electronic wire harness, based on Embodiment 1, such as... Figures 1-5As shown, the wire-receiving cavity also includes a second protective groove 5 and a second wire-receiving groove. A second protective sleeve 2 is provided on the outer surface of the first protective sleeve 3. A second limiting plate 7 is fixed to the end of the second protective sleeve 2 away from the free end of the electronic wire harness 4. The second limiting plate 7 slides in the second protective groove 5 and is located between the free end of the electronic wire harness 4 and the second wire-receiving groove. The electronic wire harness 4 between the second limiting plate 7 and the second wire-receiving groove is bent in the second wire-receiving groove to form a second bent portion 16. The second bent portion 16 is located between the free end of the electronic wire harness 4 and the first limiting plate 10. The length of the second protective groove 5 is greater than the length of the electronic wire harness 4 in the second bent portion 16. This design can protect the electronic wire harness 4 when it is pulled, preventing the connection between the electronic wire harness 4 and the connector from breaking due to pulling, ensuring the normal operation of the circuit, and extending its service life. By providing a second protective sleeve 2 on the outer surface of the first protective sleeve 3, the electronic wire harness 4 is provided with double protection. When the electronic wire harness 4 is pulled, the electronic wire harness 4 at the second bent portion 16 will be pulled first, protecting the connection between the electronic wire harness 4 and the plug 1. To prevent tension, the length of the second protective groove 5 is greater than the length of the electronic wire harness 4 of the second bending section 16. This allows the electronic wire harness 4 of the second bending section 16 to be straightened and then continue to pull the electronic wire harness 4 of the first bending section 13. A second limiting plate 7 is provided at the end of the second protective sleeve 2, causing the second protective sleeve 2 to be under tension. When the second limiting plate 7 reaches the end of the second protective groove, the tension and the reaction force of the second protective groove on the second limiting plate 7 act directly on the second protective sleeve 2, protecting the internal electronic wire harness 4. When the first limiting plate 10 first... When the first protective groove reaches its end, the pulling force and the reaction force of the first protective groove on the first limiting plate 10 act directly on the first protective sleeve 3, protecting the internal electronic wire harness 4. While the electronic wire harness 4 can be pulled, the first limiting plate 10 and the second limiting plate 7 limit the length that the electronic wire harness 4 can be pulled, keeping the electronic wire harness 4 between the first limiting plate 10 and the first wire groove in a relaxed state. This ensures that the connection between the electronic wire harness 4 and the plug 1 is free from pulling force, extends the service life, and makes the circuit connection more stable.
[0039] In this embodiment, as Figure 2 As shown, a second elastic element is provided in the second protective groove 5. One end of the second elastic element is fixedly connected to the second limiting plate 7, and the other end of the second elastic element is fixedly connected to the end of the second protective groove 5 away from the second limiting plate 7. The second elastic element is a second return spring 6. By setting the second return spring 6 as the second elastic element, when the external pulling force is lost, the pulled-out electronic wire bundle 4 can be reset under the action of the elastic restoring force of the second elastic element. At the same time, in the case of accidental pulling, the elastic restoring force of the second elastic element can provide force feedback to the puller, reminding the puller to stop pulling. When the first elastic element and the second elastic element are compressed at the same time, the elastic restoring forces of the first elastic element and the second elastic element are superimposed, making the feedback more obvious.
[0040] In this embodiment, as Figure 2 As shown, by controlling the cross-sectional shape and size of the first and second wire grooves, the first curved portion 13 and the second curved portion 16 are made into a spiral shape to prevent entanglement.
[0041] When the electronic wire harness 4 is pulled by pulling the second protective sleeve 2, the electronic wire harness 4 at the second bend 16 is pulled first. At this time, the second limiting plate 7 overcomes the elastic restoring force of the second return spring 6 and compresses the second return spring 6. Since the length of the second protective groove 5 is greater than the length of the electronic wire harness 4 at the second bend 16, the electronic wire harness 4 at the second bend 16 is straightened under continuous pulling, thereby pulling the electronic wire harness 4 at the first bend 13. At this time, the first limiting plate 10 overcomes the elastic restoring force of the first return spring 9 and compresses the first return spring 9. When the length of the second protective groove 5 is greater than the sum of the length of the electronic wire harness 4 at the second bend 16 and the length of the first protective groove 8, the first limiting plate 10 first reaches the end of the first protective groove 8 near the free end of the electronic wire harness 4. The reaction force generated by the pulling between the first limiting plate 10 and the first protective groove 8 acts on the first protective sleeve 3 to protect the electronic wire harness 4 inside. At this time, the first limiting plate 10 limits the electronic wire harness 4. Since the length of the first protective groove 8 is not greater than the length of the first bend 16, the electronic wire harness 4 at the second bend 16 is straightened under continuous pulling. The length of the electronic wire harness 4 in the first bending section 13 is such that the electronic wire harness 4 is always in a relaxed, unstressed state, ensuring the stability of the connection between the electronic wire harness 4 and the plug 1. When the length of the second protective groove 5 is less than the sum of the length of the electronic wire harness 4 in the second bending section 16 and the length of the first protective groove 8, the second limiting plate 7 first reaches the end of the second protective groove 5 near the free end of the electronic wire harness 4. The reaction force generated by the pulling between the second limiting plate 7 and the second protective groove 5 acts on the second protective sleeve 2, protecting the electronic wire harness 4 inside. At this time, the second limiting plate 7 limits the electronic wire harness 4. At this time, the first limiting plate 10 has not yet reached the end of the first protective groove 8 near the free end of the electronic wire harness 4. The electronic wire harness 4 in the first bending section 13 is in a bent state, ensuring the stability of the connection between the electronic wire harness 4 and the plug 1. In case of accidental pulling, when the electronic wire harness 4 loses tension, the elastic restoring force on the first return spring 9 and the second return spring 6 will act on the first limiting plate 10 and the second limiting plate 7 respectively, thereby driving the electronic wire harness 4 to retract and reset.
[0042] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the protection scope of this utility model. These will not affect the implementation effect or the practicality of this utility model.
