Description

Technical Field

[0001] The utility model belongs to the technical field of wire and cable, and particularly relates to a corrosion-resistant wire and cable. Background Art

[0002] Wire and cable are wire products used to transmit electrical (magnetic) energy, information and realize the conversion of electromagnetic energy. They are common products in the national economy, playing an important role in daily life and industrial production, and are an indispensable part of power, communication and other systems.

[0003] The manufacturing of wire and cable involves various processes, including drawing, stranding, coating, etc. Among them, the drawing process is mainly used to change the cross-sectional area shape and size of metals; the stranding process is used to improve the softness and integrity of wire and cable; and the coating process coats different materials outside the conductor according to different performance requirements of wire and cable.

[0004] At present, after two sections of wire and cable are butted, the common practice is to use electrical tape to wrap the butted end to isolate the external environment. However, although this method can effectively protect the connection end, the protective layer outside the end part of the butted ends of the two sections of wire and cable will be directly exposed to the external environment. More unfavorably, the part wrapped with electrical tape will gradually be corroded by environmental factors such as rainwater after long-term use. Over time, this corrosion will cause the electrical tape to gradually fail, thus making the connection end of the wire and cable face the risk of damage. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a corrosion-resistant wire and cable, aiming to solve the problem that after two sections of wire and cable are butted, the common practice is to use electrical tape to wrap the butted end to isolate the external environment. However, although this method can effectively protect the connection end, the protective layer outside the end part of the butted ends of the two sections of wire and cable will be directly exposed to the external environment. More unfavorably, the part wrapped with electrical tape will gradually be corroded by environmental factors such as rainwater after long-term use. Over time, this corrosion will cause the electrical tape to gradually fail, thus making the connection end of the wire and cable face the risk of damage.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a corrosion-resistant wire and cable, including a wire body, and a tightening ring is respectively installed on the outer wall of the butted ends of the two wire bodies;

[0007] A corrugated pipe is connected between the two tightening rings, and the connection end of the corrugated pipe and the corresponding tightening ring is a sealed structure.

[0008] In order to enable the tightening ring to be fixedly installed on the wire body, as an optimal choice for a corrosion-resistant wire and cable of the present utility model, annular grooves are respectively formed on the outer walls of the wire body near both ends. An inner groove is further formed on the inner wall at the central end of the annular groove, and a sealing ring is fixedly adhered to the inner wall of the inner groove.

[0009] In order to enable the sealing ring to be hermetically docked with the notch, as an optimal choice for a corrosion-resistant wire and cable of the present utility model, two sealing rings are adhered to the inner groove, and the two sealing rings are symmetric with respect to the longitudinal center line of the inner groove. The tightening ring is made of deformable hard insulating rubber, and an interference connection structure is formed between the tightening ring and the annular groove.

[0010] In order to form a sealing structure between the tightening ring and the annular groove, as an optimal choice for a corrosion-resistant wire and cable of the present utility model, an inner ring is hermetically adhered to the inner wall of each tightening ring. A notch is formed on the inner wall of the inner ring. The notch is symmetrically formed in two circles on the inner wall of the inner ring, and the distance between the two inner rings is adapted to the distance between the two sealing rings. The connection end between the inner ring and the sealing ring is a sealing structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] When two wire bodies are docked, first sleeve the corrugated pipe on the wire body. After the two wire bodies are docked, move the corrugated pipe at this time so that the tightening rings at both ends of the corrugated pipe are docked with the annular grooves on the corresponding wire bodies. In this way, an effective sealing structure will be formed at the connection end between the tightening ring and the annular groove, so that the connection end of the two wire bodies can be effectively isolated from the outside world. Furthermore, when in use, it can prevent the outside environment or rainwater from seeping into the wire body through the docking port of the wire body and causing corrosion.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A corrosion-resistant wire and cable, including a wire body 1, and a tightening ring 2 is respectively installed on the outer walls of the butt ends of the two wire bodies 1;

[0021] The wire body 1 is the wire or cable in the name of this technical solution.

[0022] A bellows 3 is connected between the two tightening rings 2. The length of the bellows 3 can be stretched as needed during use. The connection end of the bellows 3 and the corresponding tightening ring 2 is a sealed structure.

[0023] Preferably: annular grooves 101 are respectively opened on the outer walls of the wire body 1 near both ends. An inner groove 102 is further opened on the inner wall at the central end of the annular groove 101, and a sealing ring 103 is fixedly bonded to the inner wall of the inner groove 102. Two sealing rings 103 are bonded on the inner groove 102, and the two sealing rings 103 are symmetric with respect to the longitudinal center line of the inner groove 102. An inner ring 201 is respectively and hermetically bonded to the inner wall of each tightening ring 2, and a notch 202 is opened on the inner wall of the inner ring 201. The notch 202 is symmetrically opened in two circles on the inner wall of the inner ring 201. The distance between the two inner rings 201 is adapted to the distance between the two sealing rings 103. The connection end between the inner ring 201 in the circle and the sealing ring 103 is a sealed structure. The tightening ring 2 is made of deformable hard insulating rubber material, and the tightening ring 2 and the annular groove 101 are in an interference connection structure.

[0024] During specific use, after the tightening ring 2 is butted with the annular groove 101, the inner ring 201 inside the tightening ring 2 will be butted with the inner groove 102. In this way, the two circles of notches 202 on the inner ring 201 will be wrapped around the outer wall of the sealing ring 103 under the action of the contraction force of the tightening ring 2, so that the connection end between the notch 202 and the sealing ring 103 forms an effective sealing mechanism.

[0025] Working principle: Before the two wire bodies 1 are butted, first put the corrugated pipe 3 on one of the wire bodies 1, then butt the two wire bodies 1 according to the normal wiring process, and after the butt is completed, use electrical tape to wrap the butted end;

[0026] After the above operations are completed, adjust the corrugated pipe 3. Connect the tightening rings 2 at both ends of the corrugated pipe 3 to the annular grooves 101 on the two wire bodies 1 respectively. After the connection is completed, the tightening rings 2 will tighten and snap into the inside of the annular grooves 101. When the tightening rings 2 tighten, the inner rings 201 inside them will drive the notches 202 to squeeze against the outer wall of the sealing ring 103, thereby forming a sealing mechanism, so that an effective closed inner cavity is formed inside the corrugated pipe 3. In this way, the butted ends of the two wire bodies 1 can be effectively isolated from the outside world, so as to protect the butted ends of the wire bodies 1 from being corroded by external rainwater and other foreign objects.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
