Description

Technical Field

[0001] This utility model relates to the technical field of wire harnesses, and in particular to the technical field of spiral corrugated wire harnesses. Background Technology

[0002] The main function of wire harnesses is to connect and transmit power and signals. Wire harnesses bear the important responsibility of connecting various electrical and electronic components and ensuring their normal operation. For example, electrical control equipment inevitably uses various connecting wires. If these connecting wires are not organized, they are easy to get tangled together and are not easy to distinguish during installation and maintenance. Therefore, wire harness tubes have come into being. People can set the connecting wires in different categories in different wire harness tubes as needed, so that the connecting wires are not easy to get tangled together.

[0003] However, most existing wire harness tubes are inconvenient for users to insert wire harnesses into, and the inlet is easily blocked when inserting them, resulting in low practicality of the wire harness tubes.

[0004] To address the problems mentioned above, for example, application number CN202222004952.3 discloses a rubber wire harness tube, including a wire harness tube body made of rubber material. The wire harness tube body has a first annular groove inside, and a connecting ring made of rubber material is disposed inside the first annular groove. By providing a connecting mechanism, not only can the wire harness tube body be easily inserted into the wire harness tube body by opening one end through the connecting mechanism, but the wire harness tube body can also be connected to its corresponding device through the connecting mechanism. Furthermore, the connection ring and rubber band can prevent the wire harness from detaching from the inside of the wire harness tube body.

[0005] However, the wire harness tube in the aforementioned patent can only organize the wire harness as a whole, but cannot organize the branches of the wire harness. Furthermore, workers need to wrap the branches of the wire harness with fireproof tape. If the wire harness malfunctions, it is quite troublesome for workers to repair and rework it.

[0006] To address the problems mentioned above, for example, application number CN202321018994.0 discloses an assembled wire harness tube, including a connector. A buckle is installed at the middle position of the top of both sides of the connector. A first pipe is installed on the top of the connector via the buckle. A connecting pipe is installed on the top of the first pipe. A second pipe is installed at the bottom of the connector. The cooperation between the first pipe, the second pipe, and the connector organizes the main body and branches of the wire harness. Furthermore, fireproof tape is not required during this process. Therefore, when the wire harness malfunctions, it is convenient for workers to repair and rework it. Simultaneously, the connector does not need to be wrapped with fireproof tape, thus protecting the branches and saving workers a significant amount of time in protecting the wire harness.

[0007] However, the aforementioned patents still have the following drawbacks:

[0008] The aforementioned patent lacks a protective structure, which means that when the wire harness tube moves with external machinery, it will inevitably collide with other components during the movement, which can easily lead to wear or damage to the wire harness tube, thus affecting the performance of the wire harness. Summary of the Invention

[0009] The purpose of this invention is to solve the problems in the prior art by proposing a spiral corrugated wire harness, which can effectively protect the wire harness from damage caused by external impacts and extend the service life of the wire harness.

[0010] To achieve the above objectives, this utility model proposes a spiral corrugated wire harness, comprising a corrugated tube body, wear-resistant strips, a protective sleeve, reinforcing rings, reinforcing bars, reinforcing columns, annular grooves, and elastic clamping components. The corrugated tube body has several wear-resistant strips on its exterior, and a protective sleeve inside. Several reinforcing rings are fitted around the outside of the protective sleeve, with adjacent reinforcing rings connected by several reinforcing bars. Several reinforcing columns are welded to the outside of the reinforcing rings, and the tops of the reinforcing columns are fixedly connected to the inner wall of the corrugated tube body. Several annular grooves are formed on the inner wall of the protective sleeve, and an elastic clamping component is embedded in each annular groove, collectively clamping the wire harness within the elastic clamping components.

[0011] Preferably, the wear-resistant strips are horizontally distributed along the length of the corrugated pipe body, and the wear-resistant strips are arranged in a ring with equal spacing between them.

[0012] Preferably, the reinforcing bars are arranged in a ring with equal spacing.

[0013] Preferably, the number of reinforcing columns is four, and the four reinforcing columns are arranged in a ring with equal spacing between them.

[0014] Preferably, the elastic clamping assembly includes a high-temperature resistant metal ring, clamping springs, and a pressure plate. The high-temperature resistant metal ring is embedded in an annular groove, and the inner wall of the high-temperature resistant metal ring is provided with four clamping springs. The four clamping springs are symmetrically distributed vertically and horizontally, and the end of each clamping spring is connected to a pressure plate with an arc-shaped structure.

[0015] Preferably, the clamping surface of the clamping plate is provided with anti-slip texture, and the anti-slip texture is serrated.

[0016] Preferably, the protective sleeve is a high-temperature resistant protective sleeve.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model can effectively protect the wire harness through the combined action of wear-resistant strips, protective sleeves, reinforcing rings, steel bars, and reinforcing columns. The wear-resistant strips are designed to make initial contact with other components and withstand friction or impact, thus protecting the wire harness body. The protective sleeves further protect the wire harness, while the reinforcing rings and steel bars increase the strength of the protective sleeves, thus effectively protecting the wire harness. The reinforcing columns provide support and connection, ensuring that the protective sleeves do not move within the corrugated pipe body.

[0019] 2. This utility model, by setting up an elastic clamping component, when the wire harness passes through the high-temperature resistant metal ring, the clamping spring is compressed by external force and contracts, which in turn drives the pressure plate to contract. During the deformation process, internal stress is generated inside the clamping spring, which converts the external force into stored elastic potential energy. When the wire harness completely passes through the high-temperature resistant metal ring, the clamping spring generates a reverse force due to the release of internal stress, pushing the pressure plate to stick tightly to the surface of the wire harness, thereby playing a clamping role and preventing the wire harness from shifting.

Detailed Implementation

[0025] See Figures 1 to 4 This utility model includes a corrugated pipe body 1, wear-resistant strips 2, a protective sleeve 3, reinforcing rings 4, reinforcing bars 5, reinforcing columns 6, annular grooves 7, and elastic clamping components 8. The corrugated pipe body 1 has several wear-resistant strips 2 on its exterior, and a protective sleeve 3 inside. Several reinforcing rings 4 are fitted around the outside of the protective sleeve 3, and adjacent reinforcing rings 4 are connected by several reinforcing bars 5. Several reinforcing columns 6 are welded to the outside of the reinforcing rings 4, and the top of each reinforcing column 6 is fixedly connected to the inner wall of the corrugated pipe body 1. Several annular grooves 7 are formed on the inner wall of the protective sleeve 3, and an elastic clamping component 8 is embedded in each annular groove 7. The elastic clamping components 8 collectively clamp a wire harness.

[0026] See Figure 1 The wear-resistant strips 2 are horizontally distributed along the length of the corrugated pipe body 1, and the wear-resistant strips 2 are arranged in a ring with equal spacing. By setting the wear-resistant strips 2, they can first come into contact with other components and withstand friction or impact, thereby protecting the wire harness body.

[0027] See Figure 2 The steel bars 5 are arranged in a ring at equal intervals, which can increase the strength of the protective sleeve 3 itself and make the protective sleeve 3 less prone to breakage.

[0028] See Figure 2 The number of reinforcing posts 6 is four, and the four reinforcing posts 6 are arranged in a ring with equal spacing, which can further improve the overall strength of the protective sleeve 3, thereby effectively protecting the wire harness body.

[0029] See Figure 3The elastic clamping assembly 8 includes a high-temperature resistant metal ring 81, clamping springs 82, and a pressure plate 83. The high-temperature resistant metal ring 81 is embedded in the annular groove 7. The inner wall of the high-temperature resistant metal ring 81 is provided with four clamping springs 82, which are symmetrically distributed vertically and horizontally. Each clamping spring 82 is connected to an arc-shaped pressure plate 83 at its end. When the wire harness passes through the high-temperature resistant metal ring 81, the clamping springs 82 are compressed by external force and contract, which in turn causes the pressure plate 83 to contract. During the deformation process, internal stress is generated inside the clamping springs 82, which converts the external force into elastic potential energy and stores it. When the wire harness completely passes through the high-temperature resistant metal ring 81, the clamping springs 82 generate a reverse force due to the release of internal stress, which pushes the pressure plate 83 to press tightly against the surface of the wire harness, thereby playing a clamping role and preventing the wire harness from shifting.

[0030] See Figure 3 The clamping surface of the clamping plate 83 is provided with anti-slip texture 833, which is serrated. When the clamping plate 83 is in close contact with the surface of the wire harness, the anti-slip texture 833 can increase the friction between the clamping plate 83 and the wire harness, thereby further playing a limiting role.

[0031] See Figure 1 The protective sleeve 3 is a high-temperature resistant protective sleeve, which improves the safety of the device during use and reduces the impact on other wiring harnesses caused by overheating or short circuits.

[0032] The working process of this utility model:

[0033] In the operation of this utility model, the spiral corrugated wire harness has wear-resistant strips 2 that allow it to make initial contact with other components and withstand friction or impact, thus protecting the wire harness body. The protective sleeve 3 further protects the wire harness, while the reinforcing ring 4 and steel bar 5 increase the strength of the protective sleeve 3, thus effectively protecting the wire harness. The reinforcing column 6 provides support and connection, ensuring that the protective sleeve 3 does not move within the corrugated tube body 1.

[0034] When the wire harness passes through the high-temperature resistant metal ring 81, the clamping spring 82 is compressed by external force and contracts, which in turn drives the pressure plate 83 to contract. During the deformation process, internal stress is generated inside the clamping spring 82, which converts the external force into elastic potential energy and stores it. When the wire harness has completely passed through the high-temperature resistant metal ring 81, the clamping spring 82 generates a reverse force due to the release of internal stress, which pushes the pressure plate 83 to stick tightly to the surface of the wire harness, thereby playing a clamping role and preventing the wire harness from shifting.

[0035] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
