Description

Technical Field

[0001] The utility model relates to the technical field of copper strips, in particular to a corrosion-resistant copper strip. Background Art

[0002] Copper strip is a metal component, which is mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, connectors, and is mainly used as conductive, heat conductive, and corrosion resistant equipment.

[0003] When the copper busbar is fixedly installed, a metal mounting bracket needs to be installed at the bottom by bolts. The metal mounting bracket is arranged at the bottom of the copper busbar, which is easy to cause wear on the outer surface of the copper busbar, thereby easily damaging the protective film arranged on the surface of the copper busbar. The corrosion of the copper busbar also starts from the worn protective film, which is easy to cause damage to the copper busbar and reduce the service life of the copper busbar.

[0004] Chinese patent CN217955455U discloses a corrosion-resistant T-row copper belt, which has a mounting groove on the inner side of the copper belt body, a limiting groove on the bottom end of the mounting groove, and a first mounting hole on the top end of the copper belt body, so that a metal mounting bracket can be arranged on the inner side of the mounting groove, and the metal mounting bracket can be fixedly connected to the inner side of the mounting groove by fastening bolts through the setting of the first mounting hole, effectively avoiding directly fixing the metal mounting bracket on the bottom end of the copper belt body, reducing the wear on the outer surface of the copper belt body, and improving the service life of the copper belt body.

[0005] However, in the above-mentioned referenced documents, when the copper busbar is fixedly installed, it is still necessary to pass the fixing bolts through the mounting holes on the surface of the copper belt to complete the fixation between the metal mounting bracket and the copper belt body. The opening of the mounting holes on the surface of the copper belt is still easy to cause the wear of the surface protective film, and the protective film is easily damaged, which reduces the corrosion resistance of the copper belt. At the same time, only one protective layer is set on the surface of the copper belt, and the corrosion resistance and wear resistance of the copper belt are poor, which reduces the service life of the copper belt. Utility Model Content

[0006] The purpose of the utility model is to provide a corrosion-resistant copper strip, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a corrosion-resistant copper strip, comprising a copper strip substrate, a metal mounting bracket is arranged on the side of the copper strip substrate, two symmetrically arranged mounting holes are opened on the surface of the metal mounting bracket, an insert block is fixedly connected to the surface of the metal mounting bracket, a side of the insert block away from the metal mounting bracket is arranged in an arc shape, and a slot for inserting the insert block is opened on the side of the copper strip substrate;

[0008] A fixing component for fixing the insert block is arranged in the slot;

[0009] Also included are auxiliary components for enhancing the corrosion resistance of the copper strip substrate.

[0010] Preferably, the fixing component comprises two elastic plates symmetrically arranged on the inner wall of the copper strip substrate, and a spring 1 and a spring 2 are commonly arranged between the two elastic plates and the inner wall of the copper strip substrate.

[0011] Preferably, the fixing component further comprises an arc-shaped block fixedly connected to the surface of the elastic plate, the surface of the insert block is provided with a slide groove for the arc-shaped block to slide into and adapt to, and the inner wall of the slide groove is arc-shaped.

[0013] Preferably, the auxiliary component comprises an anti-corrosion layer bonded to the upper and lower sides of the copper strip substrate, and a glass fiber cloth layer is provided on the outer surface of the anti-corrosion layer.

[0014] Preferably, the outer surface of the glass fiber cloth layer is provided with a wear-resistant layer, and the material used for the wear-resistant layer is aluminum oxide.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model fixes the plug-in block on the surface of the metal mounting bracket with the slot on the side of the copper belt substrate and inserts it. Under the action of the elastic potential energy of the elastic plate, spring one and spring two, the plug-in block can be fixed, and the sliding groove limits the arc block so that the plug-in block will not move easily in the slot.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figures 1 to 4 The utility model provides a corrosion-resistant copper strip, comprising a copper strip substrate 1, a metal mounting bracket 2 is arranged on the side of the copper strip substrate 1, two symmetrically arranged mounting holes 6 are opened on the surface of the metal mounting bracket 2, an insert block 7 is fixedly connected to the surface of the metal mounting bracket 2, the insert block 7 is arranged in an arc shape away from the side of the metal mounting bracket 2, and a slot 9 for inserting the insert block 7 is opened on the side of the copper strip substrate 1;

[0026] A fixing component for fixing the insert block 7 is provided in the slot 9;

[0027] Auxiliary components for enhancing the corrosion resistance of the copper strip substrate 1 are also included.

[0028] More specifically, when the present embodiment is in use, the insert block 7 on the surface of the metal mounting bracket 2 is first aligned with the slot 9 on the side of the copper strip base 1 and inserted. Under the action of the fixing component in the slot 9, the copper strip base 1 and the metal mounting bracket 2 can be fixed without passing bolts through the copper strip base 1, effectively avoiding the problem of opening the mounting hole 6 on the copper strip base 1, which easily causes the outer surface protective layer of the copper strip base 1 to wear, thereby improving the service life of the copper strip base 1.

[0029] After the insert block 7 is inserted into the slot 9 to complete the fixation between the metal mounting bracket 2 and the copper belt base 1, the external fixing bolts are inserted into the mounting holes 6 on the surface of the metal mounting bracket 2, and the copper belt base 1 can be installed at the desired location.

[0030] Under the action of the auxiliary components, the corrosion resistance of the copper strip substrate 1 can be enhanced, thereby extending the service life of the copper strip substrate 1.

[0031] Embodiment 2, based on the above embodiment:

[0032] Furthermore, the fixing component and auxiliary component in the first embodiment are disclosed. The fixing component includes two elastic plates 10 symmetrically arranged on the inner wall of the copper strip substrate 1. A spring 11 and a spring 2 13 are arranged between the two elastic plates 10 and the inner wall of the copper strip substrate 1.

[0033] The fixing component also includes an arc block 12 fixedly connected to the surface of the elastic plate 10. The surface of the insert block 7 is provided with a slide groove 8 for the arc block 12 to slide into and fit into. The inner wall of the slide groove 8 is arc-shaped.

[0034] There are two insert blocks 7 and they are symmetrically distributed around the axis of the insert blocks 7 . There are also two slots 9 and they are symmetrically distributed around the axis of the copper strip substrate 1 . The two insert blocks 7 correspond to the two slots 9 one by one.

[0035] The auxiliary component comprises an anti-corrosion layer 5 bonded to the upper and lower sides of the copper strip substrate 1 , and a glass fiber cloth layer 4 is arranged on the outer surface of the anti-corrosion layer 5 .

[0036] More specifically, when the present embodiment is in use, after the plug block 7 on the surface of the metal mounting bracket 2 is aligned with the slot 9 on the side of the copper strip substrate 1 and inserted, as the plug block 7 is inserted, the two elastic plates 10 will be squeezed toward the inner wall of the slot 9, and at the same time, the springs 11 and 13 will be compressed. As the plug block 7 continues to be inserted, when the arc block 12 on the surface of the elastic plate 10 contacts the slide groove 8 on the surface of the plug block 7, the arc block 12 can be pressed into the slide groove 8 under the action of the elastic potential energy of the springs 11 and 13 and the elastic potential energy of the elastic plate 10. At this time, the plug block 7 will be fixed in the slot 9 and will not be easy to move. Under the action of the elastic potential energy of the springs 11 and 13 and the elastic potential energy of the elastic plate 10, the plug block 7 located in the middle of the slot 9 will be squeezed, and the fixation between the plug block 7 and the slot 9 can be completed.

[0037] Since the inner wall of the slide groove 8 is arc-shaped, the arc block 12 can move more smoothly when it is squeezed into the slide groove 8. Similarly, since the side of the plug block 7 away from the metal mounting bracket 2 is arc-shaped, the friction between the plug block 7 and the elastic plate 10 when entering the slot 9 can also be reduced, so that the plug block 7 can be inserted into the slot 9 more smoothly.

[0038] The anti-corrosion layer 5 on the upper and lower sides of the copper strip substrate 1 is electroplated nickel. Nickel is easy to process, has strong corrosion resistance, especially good alkaline corrosion resistance, and has low contact resistance. By electroplating nickel on the surface of the copper strip substrate 1, the corrosion resistance of the copper strip substrate 1 can be effectively improved.

[0039] The glass fiber cloth layer 4 is mainly composed of glass fiber cloth material. Glass fiber cloth has strong corrosion resistance and can resist corrosion from strong acids, strong alkalis, aqua regia and various organic solvents, thereby further improving the corrosion resistance of the copper belt substrate 1. In addition, glass fiber cloth has high temperature resistance and can absorb a large amount of heat when encountering flame combustion and can prevent the flame from passing through the isolated air. It can effectively prevent fire and flame retardancy, thereby also improving the safety of the copper belt substrate 1 when in use.

[0040] Embodiment 3, based on the above embodiment;

[0041] Furthermore, in order to further improve the service life of the copper belt substrate 1, a wear-resistant layer 3 is provided on the outer surface of the glass fiber cloth layer 4. The material used for the wear-resistant layer 3 is alumina. Alumina is a stable oxide of aluminum and has a high hardness, thereby effectively avoiding external friction damage to the structure. Alumina has stable chemical properties, is insoluble in acids and alkalis, and is resistant to corrosion.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
