Description

Technical Field

[0001] This invention relates to the field of copper rod technology, and in particular to a copper rod with surface anti-oxidation properties. Background Technology

[0002] Copper rods play an indispensable role as a key conductive material in many fields such as power transmission and electronic equipment connections. However, traditional copper rods face numerous problems in practical applications, seriously affecting their performance and service life.

[0003] Traditional copper rods are typically made of a single material. Under high temperatures, copper readily reacts with oxygen in the air to form oxides such as copper oxide. These oxidation products form an oxide layer on the surface of the copper rod. As oxidation intensifies, the oxide layer thickens, significantly reducing the copper rod's electrical conductivity. The material and structural design of traditional copper rods also make them relatively weak in terms of impact and bending resistance. During transportation, installation, and use, copper rods inevitably suffer from external forces such as collisions, compression, and bending. When subjected to significant impact, the surface of the copper rod is prone to dents, scratches, and other damage. This damage not only affects the aesthetics of the copper rod but, more importantly, destroys its surface structure, reducing its electrical conductivity. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a surface-anti-oxidation copper rod that can solve the technical problem that copper easily reacts with oxygen in the air to form oxides such as copper oxide. These oxidation products form an oxide layer on the surface of the copper rod, and as the degree of oxidation intensifies, the oxide layer continues to thicken, leading to a significant decrease in the conductivity of the copper rod.

[0005] This utility model embodiment proposes a surface-antioxidant copper rod, comprising: a copper rod body, a protective sleeve installed on the outer side of the copper rod body to provide protection thereto, a fixing sleeve for limiting and fixing the protective sleeve installed on the copper rod body, and a connecting component installed on the fixing sleeve and the protective sleeve.

[0006] The copper rod body includes a copper core, a bottom layer, and an anti-oxidation layer; The copper core is a cylindrical copper rod; The bottom layer is a Ni-Cr alloy layer, which is sprayed onto the outside of the copper core; The antioxidant layer is a Cr2O3 layer, which is sprayed on the outside of the base layer.

[0007] Both the protective sleeve and the fixing sleeve are hollow circular tubes.

[0008] The connecting component includes a connecting sleeve, a limiting strip, and a limiting groove; The connecting sleeve can be snapped into the inside of the fixed sleeve; The limiting strips are arranged in a uniform circular array on the outside of the connecting sleeve; The limiting grooves are formed on the inner wall of the fixed sleeve, and their number and position correspond to the limiting strips.

[0009] The inner wall of the fixing sleeve is provided with a slot, and a rubber ring is engaged inside the slot.

[0010] A retaining ball is fixedly installed on the outer side of the connecting sleeve, and a groove adapted to the retaining ball is opened on the inner wall of the fixed sleeve.

[0011] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, the copper rod body adopts a multi-layer structure. The bottom layer is a Ni-Cr alloy layer deposited by plasma spraying, which enhances the adhesion between the coating and the substrate. The anti-oxidation layer is Cr2O3 or Al2O3 ceramic, with trace amounts of rare earth elements (such as Y2O3) added to refine the grains, greatly improving high-temperature oxidation resistance and effectively extending the service life of the copper rod. The protective sleeve and the fixing sleeve are both hollow circular sleeves made of PVC material and fitted onto the outside of the copper core. This combination of structure and material not only protects the copper core internally but also significantly improves its impact resistance and bending resistance, reducing damage to the copper core from external factors. The connecting component is cleverly designed, with several limiting strips evenly arranged in a ring on the outside of the connecting sleeve, and corresponding limiting grooves on the inner wall of the fixing sleeve. During installation, the limiting strips and limiting grooves are precisely inserted, effectively preventing the connecting sleeve from rotating or shifting within the fixing sleeve, greatly improving the stability and accuracy of the connection. At the same time, the outer diameter of the connecting sleeve is slightly smaller than the inner diameter of the fixing sleeve, allowing the connecting sleeve to be easily inserted into the fixing sleeve, simplifying operation and improving installation efficiency. The components are structurally well-matched, ensuring the integrity and functionality of the overall structure. Attached Figure Description

[0019] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this utility model.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0021] Reference manual attached Figures 1 to 4 The present invention provides a structure for a surface-antioxidant copper rod, comprising: a copper rod body 1, a protective sleeve 3 for protecting the outer side of the copper rod body 1, a fixing sleeve 2 for limiting and fixing the protective sleeve 3, and a connecting component 4 installed on the fixing sleeve 2 and the protective sleeve 3.

[0022] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, the copper rod body 1 adopts a multi-layer structure, which improves its high-temperature oxidation resistance and effectively extends the service life of the copper rod. The protective sleeve 3 and the fixing sleeve 2 are both hollow circular sleeves made of PVC material and fitted onto the outside of the copper rod body 1. This combination of structure and material not only protects the copper rod body 1 internally but also significantly improves its impact resistance and bending resistance, reducing damage to the copper core from external factors. The connecting component 4 is easy to operate, improving installation efficiency. The reasonable matching of the structures of each component ensures the integrity and functionality of the overall structure.

[0023] In one possible implementation, the copper rod body 1 includes a copper core 11, a bottom layer 12, and an anti-oxidation layer 13; the copper core 11 is a cylindrical copper rod; the bottom layer 12 is a Ni-Cr alloy layer sprayed on the outside of the copper core 11; the anti-oxidation layer 13 is a Cr2O3 layer sprayed on the outside of the bottom layer 12.

[0024] In this embodiment of the invention, the Ni-Cr alloy is deposited by plasma spraying to enhance the adhesion between the coating and the substrate; the anti-oxidation layer is Cr2O3 or Al2O3 ceramic, which provides chemical stability, and the addition of trace rare earth elements (such as Y2O3) refines the grains and improves high-temperature oxidation resistance.

[0025] In one possible implementation, both the protective sleeve 3 and the fixing sleeve 2 are hollow circular sleeves; both the protective sleeve 3 and the fixing sleeve 2 are made of PVC material and are fitted onto the outside of the copper core 11.

[0026] In this embodiment of the utility model, the protective sleeve 3 and the fixing sleeve 2 adopt a hollow circular sleeve structure, and are both made of PVC material and are fitted on the outside of the copper core 11. This combination of structure and material can protect the copper core 11 inside and improve the impact resistance and bending resistance of the copper core 11.

[0027] In one possible implementation, the connecting component 4 includes a connecting sleeve 41, a limiting strip 42, and a limiting groove 43. The connecting sleeve 41 can be snapped into the inside of the fixed sleeve 2. Several limiting strips 42 are arranged in a uniform annular array on the outside of the connecting sleeve 41. The limiting groove 43 is opened on the inner wall of the fixed sleeve 2, and its number and position correspond to the limiting strips 42. The connecting sleeve 41 is welded to the end of the protective sleeve 3. The fixed sleeve 2 is fixedly installed on the outside of the copper core 11. The outer diameter of the connecting sleeve 41 is slightly smaller than the inner diameter of the fixed sleeve 2, so that the connecting sleeve 41 can be inserted into the inside of the fixed sleeve 2. When installing the protective sleeve 3, first fix the fixed sleeve 2 on the outside of the copper core 11, then align the position of the limiting strip 42 on the connecting sleeve 41 with the position of the limiting groove 43 on the fixed sleeve 2, and then push the protective sleeve 3 to drive the connecting sleeve 41 into the inside of the fixed sleeve 2. At the same time, the limiting strip 42 enters the limiting groove 43, connecting the protective sleeve 3 to the fixed sleeve 2.

[0028] In this embodiment of the utility model, by uniformly arranging several limiting strips 42 in a circular array on the outer side of the connecting sleeve 41, and correspondingly opening limiting grooves 43 on the inner wall of the fixed sleeve 2, the limiting strips 42 and limiting grooves 43 are precisely inserted during installation. This structure effectively prevents the connecting sleeve 41 from rotating or shifting within the fixed sleeve 2, greatly improving the stability and accuracy of the connection. The outer diameter of the connecting sleeve 41 is slightly smaller than the inner diameter of the fixed sleeve 2. This size design allows the connecting sleeve 41 to be easily inserted into the fixed sleeve 2, simplifying the operation. During installation, simply fix the fixed sleeve 2 on the outer side of the copper core 11, align the positions of the limiting strips 42 and limiting grooves 43, and push the protective sleeve 3 to drive the connecting sleeve 41 into the fixed sleeve 2 to complete the connection, improving installation efficiency. The connecting sleeve 41 is welded to the end of the protective sleeve 3, and the fixed sleeve 2 is fixedly installed on the outer side of the copper core 11. The structural fit between the components is reasonable, which can effectively connect the protective sleeve 3 to the fixed sleeve 2, thereby achieving effective protection and connection of the copper core 11 and ensuring the integrity and functionality of the overall structure.

[0029] In one possible implementation, the inner wall of the fixing sleeve 2 is provided with a slot, and a rubber ring 5 is engaged inside the slot.

[0030] In this embodiment of the invention, the connection between the fixing sleeve 2 and the copper core 11 is sealed by the rubber ring 5 to prevent external contaminants from entering between the copper core 11 and the fixing sleeve 2 and causing contamination.

[0031] In one possible implementation, a retaining ball 7 is fixedly installed on the outer side of the connecting sleeve 41, and a groove 6 adapted to the retaining ball 7 is opened on the inner wall of the fixing sleeve 2; three retaining balls 7 are arranged in a uniform annular array on the outer side of the connecting sleeve 41, and the position of the groove 6 corresponds to the retaining ball 7.

[0032] In this embodiment of the utility model, when the connecting sleeve 41 enters the interior of the fixed sleeve 2, the retaining ball 7 is compressed and can enter the interior of the fixed sleeve 2. After the retaining ball 7 enters the interior of the fixed sleeve 2, it is engaged in the groove 6, which improves the firmness between the fixed sleeve 2 and the connecting sleeve 41 and can effectively prevent the protective sleeve 3 and the fixed sleeve 2 from separating.
