Description

Technical Field

[0001] This utility model relates to the field of electrical engineering installation, specifically a PVC cable sheath with a connection structure. Background Technology

[0002] The function of a cable is to transmit electricity and signals, or to convert electromagnetic energy. It is an electrical product and comes in many types and specifications. When transmitting electricity, a cable or power cable can be selected. The structure of a cable is generally a metal core wrapped with an insulation layer. The main function of the insulation layer is to prevent leakage. However, after long-term use, the cable is prone to wear and tear, which can damage the outer insulation layer and pose a safety hazard. Therefore, cable sheaths are usually used to protect the cable.

[0003] Chinese Patent Publication No. CN 209515248 U discloses a cable sheath and its preparation method, belonging to the field of cable sheath technology. It solves the technical problem that existing insulating sheaths are generally directly attached to the outer layer of the wrapping layer by co-extrusion, making them unsuitable for use alone, especially for cables requiring partial wrapping or repair. The cable sheath of this utility model includes a sheath body and a closing material. The sheath body consists of a surface layer, a substrate layer, a pressure-resistant layer, and an insulation layer arranged sequentially from top to bottom. The surface layer consists of integrally formed raised strips, recessed strips, a first interlocking tooth, and a second interlocking tooth. The closing material is a polyurethane adhesive.

[0004] The existing technical solutions mentioned above have the following shortcomings: they rely on co-extrusion to attach to the wrapping layer during use, making them difficult to use independently. They are not suitable for cables that require partial wrapping or repair, and they lack in terms of structural and connection design and protection performance optimization. They cannot meet the diverse needs of cables for sheaths in complex environments and have certain room for optimization. Therefore, it is necessary to design a PVC cable sheath with a connection structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a PVC cable sheath with a connection structure to solve the problem of insufficient protection performance of cable sheaths in the background art, which cannot meet the requirements of complex environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC cable sheath with a connection structure, comprising a wear-resistant outer tube, a protective sleeve, and a connecting cap. The protective sleeve is fixedly connected to the outside of the wear-resistant outer tube, and the connecting cap is connected to the outside of the protective sleeve. An anti-tensile sleeve is provided inside the wear-resistant outer tube, and an anti-interference shielding sleeve is provided inside the anti-interference shielding sleeve. An anti-bending structure layer is provided inside the anti-bending structure layer, and a cable body is uniformly provided on the outside of the anti-bending structure layer. An insulating and flame-retardant layer is provided on the outside of the cable body. An elastic clamp is fixedly connected to the outside of the wear-resistant outer tube, and a mounting base is provided on the outside of the elastic clamp. Eight sets of limiting seats are connected to the outside of the elastic clamp. Eight sets of positioning grooves are provided inside the mounting base. A baffle is fixedly fixed to the outside of the mounting base. A fixing sleeve is sleeved on the outside of the mounting base. A clip is fixedly connected to one side of the fixing sleeve, and a buckle is fixedly connected to the other side of the fixing sleeve, with the clip and the buckle connected together.

[0007] Furthermore, the outer surface of the connecting cap is provided with anti-slip texture, the inner surface of the connecting cap is provided with internal thread, and the outer surface of the mounting base is provided with external thread that matches the internal thread.

[0008] Furthermore, the wear-resistant outer tube is made of PVC, and the protective sleeve is made of rubber.

[0009] Furthermore, the anti-interference shielding sleeve is made of aluminum foil, the anti-folding structural layer is made of polyurethane, and the elastic clamp is made of elastic metal.

[0010] Furthermore, a waterproof rubber ring is provided on the outer side of the mounting base, and a sealing ring is provided on the outer side of the mounting base.

[0011] Furthermore, the waterproof rubber ring is made of rubber, and the sealing ring is made of polyurethane.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the PVC cable sheath with the connection structure achieves the functions of easy assembly and enhanced sealing;

[0013] By incorporating an elastic clamp, the elastic clamp and limiting seat are inserted into the mounting base during use. As the limiting seat continues to move in, the elastic clamp's material properties cause the end of the limiting seat to contract inwards, and then spring open at the positioning groove to press against the groove opening, thus achieving rapid assembly of the connection end. The operation is simple and convenient. Further moving the connecting cap allows it to connect with the external thread on the outside of the mounting base via its internal thread, thus strengthening the connection at the interface and preventing loosening, enhancing the convenience and flexibility of operation. After the above assembly is completed, the hinge action of the fixing sleeve causes both sides to close inwards, allowing the end of the clamp to be inserted into the buckle. The fixing sleeve provides enhanced protection at the interface, preventing moisture and dust from entering and improving the overall performance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-6 One embodiment of this utility model provides a PVC cable sheath with a connection structure, comprising a wear-resistant outer tube 1, a protective sleeve 2, and a connecting cap 3. The protective sleeve 2 is fixedly connected to the outer side of the wear-resistant outer tube 1, and the connecting cap 3 is connected to the outer side of the protective sleeve 2.

[0024] The wear-resistant outer tube 1 is provided with an anti-tensile sleeve 5 inside, and an anti-interference shielding sleeve 6 is provided inside the anti-interference shielding sleeve 5. An anti-bending structure layer 7 is provided inside the anti-bending structure layer 7, and a cable body 4 is uniformly provided on the outside of the anti-bending structure layer 7. An insulating flame-retardant layer 18 is provided on the outside of the cable body 4.

[0025] The outer side of the wear-resistant outer tube 1 is fixedly connected with an elastic clamp 8, and an installation seat 9 is provided on the outer side of the elastic clamp 8. Eight sets of limit seats 17 are connected to the outer side of the elastic clamp 8. Eight sets of positioning grooves 12 are provided inside the installation seat 9. A baffle 14 is fixedly connected to the outer side of the installation seat 9. A fixing sleeve 13 is sleeved on the outer side of the installation seat 9. A clip head 15 is fixedly connected to one side of the fixing sleeve 13, and a buckle 16 is fixedly connected to the other side of the fixing sleeve 13. The clip head 15 and the buckle 16 are connected to each other.

[0026] Specifically, such as Figure 4 and Figure 5 As shown, in use, by covering the outside of the cable body 4 with an insulating flame-retardant layer 18, and then placing the insulating flame-retardant layer 18 on the outside of the anti-bending structure layer 7, the anti-interference shielding sleeve 6 and the tensile sleeve 5 are wrapped in sequence and placed inside the wear-resistant outer tube 1. Finally, the wear-resistant outer tube 1 is passed through the protective sleeve 2 and the connecting cap 3 to complete the basic assembly of the sheath. This allows the operator to complete the assembly work in an orderly manner, and also ensures that the sheath can play its maximum role in mechanical protection, electrical performance and physical protection.

[0027] The outer surface of the connecting cap 3 is provided with anti-slip texture, the inner surface of the connecting cap 3 is provided with internal thread, and the outer surface of the mounting base 9 is provided with external thread that matches the internal thread.

[0028] Specifically, such as Figure 4 and Figure 5As shown, during use, by aligning and tightening the external thread on the outside of the connecting cap 3 and the mounting base 9, this threaded connection not only makes the connection at the sheath interface tighter and more stable, but also effectively prevents loosening caused by equipment vibration or external force. At the same time, the anti-slip texture design on the outside of the connecting cap 3 makes it easy for operators to tighten or loosen the cap when their hands are wet or oily, improving the convenience of use and work efficiency, and ensuring the stability of the cable conduit connection.

[0029] The wear-resistant outer tube 1 is made of PVC, and the protective sleeve 2 is made of rubber;

[0030] Specifically, such as Figure 1 As shown, during use, the PVC material of the wear-resistant outer tube 1 can effectively resist the wear and corrosion of the cable by external environment such as soil and sand, and protect the internal cable body 4. The rubber material of the protective sleeve 2 can provide a certain elastic buffer when the cable is subjected to slight compression or collision, reducing the direct impact on the cable body 4.

[0031] The anti-interference shielding sleeve 6 is made of aluminum foil, the anti-folding structure layer 7 is made of polyurethane, and the elastic clamp 8 is made of elastic metal.

[0032] The waterproof rubber ring 10 is made of rubber, and the sealing ring 11 is made of polyurethane.

[0033] Specifically, such as Figure 5 and Figure 6 As shown, when in use, the aluminum foil material of the anti-interference shielding sleeve 6 can effectively reflect and absorb electromagnetic waves, providing the cable with good anti-electromagnetic interference performance and ensuring the stability of signal transmission. The polyurethane material of the anti-bending structure layer 7 can effectively prevent the cable from being damaged when it is frequently bent or subjected to external impact. The elastic metal material of the elastic clamp 8 can achieve quick clamping and release during assembly, making it convenient for operators to quickly connect and disassemble. The waterproof rubber ring 10 and sealing ring 11 set on the outside of the mounting base 9 can effectively prevent external moisture, dust and other harmful substances from entering the cable sheath. The rubber material of the waterproof rubber ring 10 and the polyurethane material of the sealing ring 11 can maintain good elasticity and sealing performance.

[0034] A waterproof rubber ring 10 is provided on the outer side of the mounting base 9, and a sealing ring 11 is provided on the outer side of the mounting base 9.

[0035] Working principle: When using this utility model, the outer part of the protective sleeve 2 passes through the connecting cap 3, and then the two sets of mounting seats 9 are symmetrically fixed. The baffle 14 is aligned with the fixing groove of the fixing sleeve 13, and the clip 15 is aligned with the buckle 16 and pressed to fix it. Then, the waterproof rubber ring 10 and the sealing ring 11 are respectively put on the outer part of the mounting seat 9. Then, the elastic clamp 8 is placed inside the mounting seat 9. Finally, the wear-resistant outer tube 1 is inserted into the interior of the mounting seat 9 until the limiting clamp 17 pops out from the positioning groove 12, and one end of the wear-resistant outer tube 1 is fixed. Then, the connecting cap 3 is rotated and tightened along the thread of the mounting seat 9. Then, the next section of the wear-resistant outer tube 1 is installed in the same way.
