Description

Technical Field

[0001] This utility model belongs to the field of copper core processing for cables, specifically an anti-oxidation copper core. Background Technology

[0002] Copper core usually refers to a core conductor made primarily of copper. Due to its excellent conductivity, stability and mechanical properties, it has become the mainstream material in the electrical field and is a key component for power and signal transmission.

[0003] In existing technologies, copper cores and electrical terminals are core components that work together and are indispensable in electrical connections. Copper cores are the "carrier" for current transmission, while electrical terminals are the "hub" for current transmission. As a connecting component, the function of electrical terminals is to fix and conduct two or more copper cores (or copper cores and equipment interfaces), which is equivalent to a "bridge" to ensure that current can smoothly transition from one copper core to another or into the equipment.

[0004] Through long-term use and observation, it was found that when connecting two copper cores using terminals, a loose connection can cause the copper cores to shift further due to vibration, pulling, or temperature changes (thermal expansion and contraction), resulting in copper core breakage and circuit breakage.

[0005] Therefore, this utility model provides an anti-oxidation copper core. Utility Model Content

[0006] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, an anti-oxidation copper core is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An anti-oxidation copper core of this utility model includes a first cable, inside which is a first copper core. A second cable is correspondingly provided on the first cable, inside which is a second copper core. A terminal is installed between the first cable and the second cable. A conductive contact is assembled in the middle of the inner sidewall of the terminal. The first cable is inserted into the terminal, and the second cable is inserted into the terminal. The first copper core, the second copper core, and the conductive contact are connected together. A fixing component is provided in the middle of the sidewall of the terminal. A limiting component is provided in the middle of the sidewall of the fixing component, located outside the terminal. A tightening component is provided in the middle of the sidewall of the fixing component, located inside the terminal. The fixing component includes a pair of outer shells, which are respectively fixed to the first cable and the second cable. On the sidewall of the two cables, multiple movable rods are slidably connected to the middle of the terminal sidewall. A limit plate is fixed to the end of each movable rod, and a fixing plate is fixed to the other end of each movable rod. The fixing plate is located inside the terminal, and a spring is fixed between the limit plate and the terminal. The spring is covered outside the movable rod. This step, by setting up the outer shell, movable rod, limit plate, fixing plate, and spring, can lock the first and second cables inside the terminal, preventing them from moving freely inside the terminal. This reduces the risk of loosening or damage to the connection caused by the shaking of the first or second cable. Moreover, this setting can make the connection between the first cable, the second cable, and the terminal reliable for a long time. Even under vibration, impact, or external force, it can effectively prevent the first or second cable from accidentally falling out of the terminal. It also ensures that the first cable, the second cable, and the terminal fit tightly, reducing gaps and delaying the oxidation process.

[0008] Preferably, the limiting component includes a buckle plate, which is rotatably connected to the side wall of the limiting plate. The end of the buckle plate is tapered. Multiple limiting strips are fixed in the middle of the side wall of the outer shell. The limiting strips and the buckle plate are correspondingly arranged. An anti-slip pad is fixed in the middle of the inner side wall of the buckle plate. The anti-slip pad is made of elastic material. This step, by setting the buckle plate and the limiting strips, can fix the first cable and the second cable inside the terminal from the outside, further ensuring a stable connection between the first cable and the second cable. At the same time, it reduces the loosening of the connection caused by the shaking of the first copper core or human error, reduces signal interference and attenuation caused by poor connection or looseness, and improves the stability and reliability of conductive contact. By setting the anti-slip pad, the friction between the buckle plate and the limiting strip can be increased, improving the stable connection between the two, making it less likely to loosen or fall off under external force, and further improving the stability of the entire system.

[0009] Preferably, the wrapping assembly includes an elastic cloth, which is fixed to the side wall of the fixing plate. A plurality of protruding pads are fixed in the middle of the side wall of the elastic cloth. Both the elastic cloth and the protruding pads are made of elastic material. This step, by setting the elastic cloth and the protruding pads, can work together with the fixing assembly to firmly fix the first cable and the second cable inside the terminal, while reducing the friction between the fixing plate and the outer shell, thereby reducing wear and extending the service life of the fixing plate.

[0010] Preferably, a plurality of connecting plates are fixed in the middle of the side wall of the terminal, and a first movable plate is rotatably connected between a pair of connecting plates. A second movable plate is rotatably connected in the middle of the side wall of the first movable plate. This step of setting the connecting plates, the first movable plate and the second movable plate can be finely adjusted in angle to find the most suitable installation angle, reduce installation difficulties caused by space limitations, improve installation flexibility and adapt to complex scenarios.

[0011] Preferably, an anti-oxidation coating is provided between the outer shell and the first cable and the second cable. A pair of anti-oxidation coatings are respectively applied to the outside of the first cable and the second cable. This step, by setting the anti-oxidation coating, can form a dense physical barrier on the surface of the copper core, directly isolating the copper from contact with air, moisture and corrosive gases, preventing oxidation reaction from the source, and allowing the copper core to maintain a good conductive state for a long time.

[0012] Preferably, a handle is fixed in the middle of the side wall of the limiting plate. The handle is arranged in an arc shape. This step provides a clear gripping point by setting the handle, making it easier to exert force and improving the convenience of operation.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The anti-oxidation copper core of this utility model, by setting up a shell, a movable rod, a limiting plate, a fixing plate and a spring, can lock the first cable and the second cable inside the terminal, preventing them from moving freely inside the terminal, thereby reducing the risk of loosening or damage to the connection caused by the shaking of the first cable or the second cable. Moreover, this setting can make the connection between the first cable, the second cable and the terminal reliable for a long time. Even under vibration, impact or external force, it can effectively prevent the first cable or the second cable from accidentally falling out of the terminal. It makes the first cable, the second cable and the terminal fit tightly, reduces gaps and slows down the oxidation process.

[0015] 2. The anti-oxidation copper core of this utility model, by setting a buckle plate and a limiting strip, can fix the first cable and the second cable inside the terminal from the outside, further ensuring a stable connection between the first cable and the second cable. At the same time, it reduces the loosening of the connection caused by the shaking of the first copper core or human error, reduces signal interference and attenuation caused by poor connection or looseness, and improves the stability and reliability of conductive contact. By setting an anti-slip pad, the friction between the buckle plate and the limiting strip can be increased, improving the stable connection between the two, making it less likely to loosen or fall off under external force, and further improving the stability of the entire system.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5 As shown in the figure, an anti-oxidation copper core according to an embodiment of the present invention includes a first cable 1, a first copper core 11 inside the first cable 1, a second cable 12 correspondingly disposed on the first cable 1, a second copper core 13 inside the second cable 12, a terminal 14 installed between the first cable 1 and the second cable 12, a conductive contact 15 assembled in the middle of the inner sidewall of the terminal 14, the first cable 1 being inserted into the terminal 14, the second cable 12 being inserted into the terminal 14, the first copper core 11, the second copper core 13 and the conductive contact 15 being connected together, a fixing component being provided in the middle of the sidewall of the terminal 14, a limiting component being provided in the middle of the sidewall of the fixing component, the limiting component being disposed outside the terminal 14, and the fixing component being fixed. A tightening component is provided in the middle of the side wall of the fixed component. The tightening component is located inside the terminal 14. The installer inserts the first cable 1 and the second cable 12 to be connected into the terminal 14 respectively. At this time, the exposed first copper core 11 inside the first cable 1 and the exposed second copper core 13 inside the second cable 12 will abut against the side wall of the conductive contact 15, so that the terminal 14 connects the first copper core 11 and the second copper core 13 together. After the connection is completed, the installer pulls the fixing component, so that the fixing component, together with the tightening component, fixes the first cable 1 and the second cable 12 inside the terminal 14. Then, the limiting component is pulled to fix the first cable 1 and the second cable 12 from the outside.

[0027] like Figures 1 to 5As shown, the fixing assembly includes a pair of housings 2, which are respectively fixed to the side walls of the first cable 1 and the second cable 12. Multiple movable rods 21 are slidably connected to the middle of the side wall of the terminal 14. A limiting plate 22 is fixed to one end of each movable rod 21, and a fixing plate 23 is fixed to the other end of each movable rod 21. The fixing plate 23 is located inside the terminal 14. A spring 24 is fixed between the limiting plate 22 and the terminal 14, covering the outside of the movable rods 21. When the first cable 1 and the second cable 12 are connected together using the terminal 14, the installer releases the multiple limiting plates 22. At this time, the limiting plates 22 move under the action of the spring 24, causing the limiting plates 22 to drive the movable rods 21 and the fixing plates 23 to move simultaneously. Simultaneously, the multiple fixing plates 23 press against the outside of the terminal 14 from inside. On the surface of the housing 2, the connection positions of the first cable 1, the second cable 12, and the terminal 14 are fixed. This step, by setting the housing 2, the movable rod 21, the limiting plate 22, the fixing plate 23, and the spring 24, can lock the first cable 1 and the second cable 12 inside the terminal 14, preventing them from moving freely inside the terminal 14. This reduces the risk of loosening or damage to the connection caused by the shaking of the first cable 1 or the second cable 12. Moreover, this setting can ensure that the connection between the first cable 1, the second cable 12, and the terminal 14 is reliable for a long time. Even under vibration, impact, or external force, it can effectively prevent the first cable 1 or the second cable 12 from accidentally falling out of the terminal 14. This ensures that the first cable 1, the second cable 12, and the terminal 14 fit tightly, reducing gaps and slowing down the oxidation process.

[0028] like Figures 1 to 5 As shown, the limiting assembly includes a buckle plate 3, which is rotatably connected to the side wall of the limiting plate 22. The end of the buckle plate 3 is tapered. Multiple limiting strips 31 are fixed in the middle of the side wall of the outer shell 2, and the limiting strips 31 are correspondingly set with the buckle plate 3. An anti-slip pad 32 is fixed in the middle of the inner side wall of the buckle plate 3. The anti-slip pad 32 is made of elastic material. When multiple fixing plates 23 fix the first cable 1 and the second cable 12 from inside the terminal 14, the installer pulls the buckle plate 3 in multiple directions. At this time, the buckle plate 3 will rotate on the side wall of the limiting plate 22. Because the buckle plate 3 and the limiting strips 31 are correspondingly set, the buckle plate 3 will fasten onto the appropriately positioned limiting strip 31, thus releasing the first cable 1 and the second cable 12 from the outside. Cable 12 is fixed inside terminal 14. This step, by setting buckle plate 3 and limit strip 31, can fix the first cable 1 and the second cable 12 inside terminal 14 from the outside, further ensuring the stable connection of the first cable 1 and the second cable 12. At the same time, it reduces the loosening of the connection caused by shaking of the first copper core 11 or human error, reduces signal interference and attenuation caused by poor connection or looseness, and improves the stability and reliability of conductive contact. By setting anti-slip pad 32, the friction between buckle plate 3 and limit strip 31 can be increased, improving the stable connection between the two, making it less likely to loosen or fall off under external force, and further improving the stability of the entire system.

[0029] like Figure 3 and Figure 4 As shown, the wrapping assembly includes an elastic cloth 4, which is fixed to the side wall of the fixing plate 23. Multiple protruding pads 41 are fixed in the middle of the side wall of the elastic cloth 4. Both the elastic cloth 4 and the protruding pads 41 are made of elastic material. When the fixing plate 23 presses against the outer wall of the first cable 1 and the second cable 12, the elastic cloth 4 on the side wall of the fixing plate 23 will bind the first cable 1, and at the same time, the multiple protruding pads 41 will press against the outer wall of the first cable 1 and the second cable 12 from the inside. This step, by setting the elastic cloth 4 and the protruding pads 41, can work together with the fixing assembly to firmly fix the first cable 1 and the second cable 12 inside the terminal 14, while reducing the friction between the fixing plate 23 and the outer shell 2, thereby reducing wear and extending the service life of the fixing plate 23.

[0030] like Figures 1 to 4 As shown, multiple connecting plates 5 are fixed to the middle of the side wall of terminal 14. A first movable plate 51 is rotatably connected between a pair of connecting plates 5. A second movable plate 52 is rotatably connected to the middle of the side wall of the first movable plate 51. After connecting the first cable 1 and the second cable 12 using terminal 14, the installer pulls the multiple second movable plates 52. The second movable plates 52 will pull the first movable plate 51 to rotate, so that the first movable plate 51 rotates on the side wall of the connecting plate 5. Then, a screw is used to pass through the second movable plate 52 to fix the terminal 14 in the designated position. This step allows the connecting plate 5, the first movable plate 51 and the second movable plate 52 to be finely adjusted to find the most suitable installation angle, reducing installation difficulties caused by space limitations, improving installation flexibility and adapting to complex scenarios.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, an anti-oxidation coating 6 is provided between the outer shell 2 and the first cable 1 and the second cable 12. A pair of anti-oxidation coatings 6 are respectively covered on the outside of the first cable 1 and the second cable 12. This step can form a dense physical barrier on the surface of the copper core by setting the anti-oxidation coating 6, which directly isolates the copper from contact with air, moisture and corrosive gases, prevents oxidation reaction from the source, and keeps the copper core in a good conductive state for a long time.

[0032] like Figures 1 to 4 As shown, a handle 7 is fixed in the middle of the side wall of the limiting plate 22. The handle 7 is set in an arc shape. This step provides a clear gripping point by setting the handle 7, which makes it easier to exert force and improves the convenience of operation.

[0033] Working principle: The installer inserts the first cable 1 and the second cable 12 into the terminal 14 respectively. At this time, the exposed first copper core 11 inside the first cable 1 and the exposed second copper core 13 inside the second cable 12 will abut against the side wall of the conductive contact 15, so that the terminal 14 connects the first copper core 11 and the second copper core 13 together. After the connection is completed, the installer pulls the fixing component, so that the fixing component and the wrapping component together fix the first cable 1 and the second cable 12 inside the terminal 14. Then, the limiting component is pulled to fix the first cable 1 and the second cable 12 from the outside. When the first cable 1 and the second cable 12 are connected together using the terminal 14, the installer releases the multiple limiting plates 22. At this time, the limiting plates 22 will move under the action of the spring 24, so that the limiting plates 22 drive the movable rod 21 and the fixing plate 23 to move simultaneously. At this time, the multiple fixing plates 23 will press from the inside of the terminal 14 onto the surface of the outer shell 2, connecting the first cable 1, the second cable 12 and the... When the connection position of terminal 14 is fixed, and multiple fixing plates 23 fix the first cable 1 and the second cable 12 from inside terminal 14, the installer pulls the buckle plates 3 in multiple directions. At this time, the buckle plates 3 will rotate on the side wall of the limiting plate 22. Because the buckle plates 3 and the limiting strips 31 are set accordingly, the buckle plates 3 will fasten to the limiting strips 31 in the appropriate position, fixing the first cable 1 and the second cable 12 to the inside of terminal 14 from the outside. When the fixing plates 23 press on the outer wall of the first cable 1 and the second cable 12, the elastic cloth 4 on the side wall of the fixing plates 23 will bind the first cable 1. At the same time, multiple protruding pads 41 will press on the outer wall of the first cable 1 and the second cable 12 from the inside. After connecting the first cable 1 and the second cable 12 using terminal 14, the installer pulls multiple second movable plates 52. The second movable plates 52 will pull the first movable plate 51 to rotate, so that the first movable plate 51 rotates on the side wall of the connecting plate 5. Then, the screw is used to pass through the second movable plate 52 to fix the terminal 14 in the designated position.
