Description

Technical Field

[0001] The utility model relates to the field of stretch-resistant electronic wire harnesses, in particular to a stretch-resistant electronic wire harness. Background Art

[0002] Anti-stretch electronic wiring harness is a specially designed connection harness used in electronic systems. It is made of materials with high tensile strength, such as certain special plastics, synthetic fibers, etc., to ensure that it is not easy to break when pulled by external forces, and can resist friction and wear in daily use to maintain stable performance.

[0003] The existing stretch-resistant electronic wiring harness includes the wire body itself and the connecting end part. When the existing stretch-resistant electronic wiring harness is used in an environment prone to vibration, the connected plug or connector part may be easily damaged or deformed due to repeated stretching of the wire body itself and large external force.

[0004] To this end, a stretch-resistant electronic wire harness is proposed. Utility Model Content

[0005] In view of the above problems, the utility model provides a stretch-resistant electronic wire harness to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] A stretch-resistant electronic wire harness comprises a wire harness and an end. An anti-stretch component is arranged between the wire harness and the end. The anti-stretch component comprises an absorption sleeve between the wire harness and the end. One end of the absorption sleeve is sleeved on the outer surface of the wire harness. The absorption sleeve is located on the outer surface of one end of the wire harness and is clamped with a plurality of tightly fitting clamping rings. The other end of the absorption sleeve is fixedly connected to the outer surface of the end. The inner wall of the absorption sleeve is provided with a reinforcement surface, and the surface of the reinforcement surface is provided with spiral patterns.

[0008] The working principle of the above technical solution is as follows:

[0009] When external force begins to exert tensile force on the wiring harness, the force will first be transmitted to the absorption sleeve to initially bear and disperse part of the tensile force. As the tensile force continues to act, the spiral pattern on the surface of the reinforced surface begins to play a role, and the tensile force is transmitted along the spiral path on the surface of the reinforced surface, dispersing the force evenly to various parts of the absorption sleeve, avoiding local concentration of force and reducing direct impact on the connection between the absorption sleeve and the wiring harness.

[0010] In a further technical solution, a rubber gasket is fixedly connected to the outer surface of one end of the absorbing sleeve close to the terminal, and the end of the rubber gasket away from the absorbing sleeve is fixed to the surface of the terminal. By arranging the rubber gasket at the connection between the absorbing sleeve and the terminal, a buffering and sealing effect can be achieved, reducing the direct impact of the terminal on the wiring harness when it is stretched.

[0011] In a further technical solution, the absorption sleeve is in a cone shape with one end larger than the other, and the spiral pattern on the surface of the reinforcement surface is arranged in a progressive state along the shape of the absorption sleeve. By arranging the absorption sleeve in a cone shape with one end larger than the other, the diameter from the wire harness to the end can be gradually changed, so that the tensile force can be transferred more evenly, reducing the risk of stress concentration and local damage caused by sudden changes in diameter. When subjected to tensile force, the conical shape can produce a certain deformation buffer, absorb part of the energy, thereby reducing the impact on other parts, and further improving the tensile resistance of the wire harness.

[0012] In a further technical solution, the small end of the absorbent sleeve is located on the surface of the wire harness, and a groove matching the clamping ring is provided on the outer surface of the absorbent sleeve, and the inner side of the clamping ring is fitted with the inner wall of the groove. By setting the small end of the absorbent sleeve to be combined with the wire harness and the large end to be connected with the terminal, the stability of the overall connection is improved, and it is not easy to loosen or slip when stretched. When the wire harness is subjected to a tensile force, the force will first be transmitted to the conical absorbent sleeve, and then dispersed and transmitted through the spiral pattern on the surface of the reinforcing surface and the conical structure of the absorbent sleeve, so that the tensile force can be more evenly distributed on the entire absorbent sleeve, thereby better protecting the connection between the wire harness and the terminal and improving its tensile resistance.

[0013] In a further technical solution, a protective sleeve is fixedly connected to the outer surface of the anti-stretch component, and the protective sleeve is woven by aramid fibers.

[0014] In a further technical solution, the material of the absorption sleeve is engineering plastic, which has high elasticity and toughness and optimizes the anti-stretching effect.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] By arranging an absorption sleeve on the outer surface of one end of the wiring harness and clamping a plurality of tightly fitting clamping rings, the clamping rings can be used to tightly combine the absorption sleeve and the wiring harness, thereby playing a role in preliminary fixation and strengthening the connection. In addition, the absorption sleeve connected between the wiring harness and the end head, utilizing the reinforcing surface with spiral patterns on the inner wall of the absorption sleeve, can effectively disperse the tensile force when the wiring harness and the end head are subjected to vibration tensile force, thereby improving the anti-stretching effect at the end head of the existing anti-stretching electronic wiring harness.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0026] Example:

[0027] See also Figure 1-4 A stretch-resistant electronic wire harness comprises a wire harness 1 and an end 2, an anti-stretch component 3 is arranged between the wire harness 1 and the end 2, the anti-stretch component 3 comprises an absorption sleeve 31 between the wire harness 1 and the end 2, one end of the absorption sleeve 31 is sleeved on the outer surface of the wire harness 1, the absorption sleeve 31 is located on the outer surface of one end of the wire harness 1 and is clamped with a plurality of tightly fitting clamping rings 32, the other end of the absorption sleeve 31 is fixedly connected to the outer surface of the end 2, the inner wall of the absorption sleeve 31 is provided with a reinforcement surface 34, and the surface of the reinforcement surface 34 is provided with spiral patterns.

[0028] The working principle of the above technical solution is as follows:

[0029] When external force begins to apply tensile force to the wiring harness 1, the force will first be transmitted to the absorption sleeve 31 to initially bear and disperse part of the tensile force. As the tensile force continues to act, the spiral pattern on the surface of the reinforcement surface 34 begins to play a role, and the tensile force is transmitted along the spiral path on the surface of the reinforcement surface 34, and the force is evenly dispersed to various parts of the absorption sleeve 31, avoiding local concentration of force and reducing direct impact on the connection between the absorption sleeve 31 and the wiring harness 1. By arranging the absorption sleeve 31 to be located on the outer surface of one end of the wiring harness 1 and clamped with multiple tightly fitting clamping rings 32, the absorption sleeve 31 can be tightly combined with the wiring harness 1 by using the clamping ring 32, which plays a role of preliminary fixing and strengthening the connection. In addition, the absorption sleeve 31 connected between the wiring harness 1 and the terminal 2, using the reinforcement surface 34 with spiral patterns on the inner wall of the absorption sleeve 31, can effectively disperse the tensile force when the wiring harness 1 and the terminal 2 are subjected to vibration tensile force, thereby improving the anti-stretching effect at the terminal 2 of the existing stretch-resistant electronic wiring harness.

[0030] See also Figure 1 and Figure 3 The outer surface of the end of the absorbing sleeve 31 close to the terminal 2 is fixedly connected with a rubber gasket 33, and the end of the rubber gasket 33 away from the absorbing sleeve 31 is fixed to the surface of the terminal 2. By arranging the rubber gasket 33 at the connection between the absorbing sleeve 31 and the terminal 2, a buffering and sealing effect can be achieved, reducing the direct impact of the terminal 2 on the wiring harness 1 when being stretched.

[0031] See also Figure 3 The absorbing sleeve 31 is in a cone shape with one end larger than the other, and the spiral pattern on the surface of the reinforcing surface 34 is arranged in a progressive state along the shape of the absorbing sleeve 31. By setting the absorbing sleeve 31 in a cone shape with one end larger than the other, the diameter from the wire harness 1 to the end 2 can be gradually changed, so that the tensile force can be transferred more evenly, reducing the stress concentration and local damage risks caused by sudden changes in diameter. When subjected to tensile force, the conical shape can produce a certain deformation buffer, absorb part of the energy, thereby reducing the impact on other parts, and further improving the tensile resistance of the wire harness 1.

[0032] See also Figure 3The small end of the absorbing sleeve 31 is located on the surface of the wire harness 1, and a groove 35 matching the clamp ring 32 is provided on the outer surface of the absorbing sleeve 31, and the inner side of the clamp ring 32 is in contact with the inner wall of the groove 35. By setting the small end of the absorbing sleeve 31 to be combined with the wire harness 1 and the large end to be connected with the terminal 2, the stability of the overall connection is improved, and it is not easy to loosen or slip when stretched. When the wire harness 1 is subjected to a tensile force, the force will first be transmitted to the conical absorbing sleeve 31, and then dispersed and transmitted through the spiral pattern on the surface of the reinforcing surface 34 and the conical structure of the absorbing sleeve 31, so that the tensile force can be more evenly distributed on the entire absorbing sleeve 31, thereby better protecting the connection between the wire harness 1 and the terminal 2 and improving its tensile resistance.

[0033] See also Figure 1 and Figure 3 The outer surface of the anti-stretching component 3 is fixedly connected with a protective sleeve 4, and the protective sleeve 4 is formed by weaving aramid fibers.

[0034] See also Figure 3 The material of the absorption sleeve 31 is engineering plastic, which has high elasticity and toughness and optimizes the anti-stretching effect.

[0035] During operation, when external force acts on the wiring harness 1, first, the protective cover on the outer surface of the wiring harness 1 itself will bear part of the tensile force, and its wear resistance and tensile resistance will play a role, trying to maintain the overall shape of the wiring harness 1 and the terminal 2, and then the protective cover 4 will resist the stretching through its high strength and toughness, disperse the force to a larger area, and reduce local stress concentration. Then the spiral pattern on the surface of the reinforcing surface 34 will further disperse the transmitted tensile force, and transmit and buffer the force to the surroundings along the spiral path. At this time, the conical absorption cover 31, by virtue of its shape and structural design and the material properties of the plastic, assists the reinforcing surface 34 to better disperse the tensile force and ensure the stability of the connection between the wiring harness 1 and the terminal 2, and the strength of the terminal 2 itself will also play a role in resisting a certain tensile force to ensure the reliability of the connection with the equipment. During the whole process, various parts work together to resist the tensile force to ensure that the electronic wiring harness can still transmit signals or electrical energy normally under stretching.

[0036] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
