Their core function is to achieve a safe and reliable transition between copper and aluminum wires, avoid connection failures caused by material differences, and ensure the conductivity and long-term stability of the circuit.

[0003] When using tubular copper-aluminum terminals to connect copper and aluminum wires, traditional methods often involve manual connection, which is prone to errors. The current common method is to remove and reconnect the terminals. However, while this method allows for reinstallation, it is time-consuming and can damage the removed wires. Utility Model Content

[0008] Specifically, the terminals include copper tubes and aluminum tubes, with the aluminum tubes mounted on the copper tubes.

[0009] Specifically, a protective mechanism is provided on the outside of the terminal. The protective mechanism includes a first protective shell, a second protective shell, a locking block, and a fixing component. The first protective shell is disposed on the outside of the terminal. The second protective shell is rotatably connected to the first protective shell. A connecting groove is opened on the side wall of the second protective shell.

The inner wall of the connecting groove has a mounting hole, the second spring is disposed in the mounting hole, the latch is connected to the other end of the second spring, and the outer wall of the locking block has a limit hole.

[0011] Specifically, a moisture-proof shell is fitted over the first protective shell, and a slot is provided inside the moisture-proof shell.

[0012] Compared with the prior art, the present invention has the following advantages: by changing the connection method between the terminal and the wire, when it is installed on the corresponding wire, the copper or aluminum wire connected to it can be replaced according to actual needs without removing the terminal from the wire, thereby reducing the time consumed when replacing the corresponding wire.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following describes an embodiment of the present invention, a VE cold-pressed tube type copper-aluminum terminal, with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown in the figure, a VE cold-pressed tube type copper-aluminum terminal according to an embodiment of the present invention includes: a terminal 1 and a mounting mechanism 2. The mounting mechanism 2 is disposed on the terminal 1. The mounting mechanism 2 includes a first spring 22, a limiting block 23 and a slider 26. A sliding groove 21 is provided in the terminal 1. The first spring 22 is disposed in the sliding groove 21. The limiting block 23 is connected to the other end of the first spring 22. A limiting groove 24 is provided in the inner wall of the sliding groove 21. A connecting hole 25 is provided in the inner wall of the sliding groove 21. The slider 26 is disposed on the outer wall of the terminal 1. A control ring 27 is sleeved on the outside of the terminal 1.

[0019] Specifically, when using terminal 1 to transition between copper and aluminum wires, the copper and aluminum wires are fixed in the corresponding copper tube 11 and aluminum tube 12 respectively. Then, the aluminum tube 12 is inserted into the copper tube 11. At this time, the slider 26 on the outer wall of the aluminum tube 12 will move along the direction of the slide groove 21 and press the limiting block 23. Then, the aluminum tube 12 is rotated to slide the slider 26 from the slide groove 21 to the limiting groove 24. At this time, the limiting block 23, which is no longer pressed by the slider 26, will pop out under the action of the first spring 22 and block the opening of the limiting groove 24, thereby fixing it.

[0020] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, terminal 1 includes a copper tube 11 and an aluminum tube 12, with the aluminum tube 12 disposed on the copper tube 11.

[0021] Specifically, when using terminal 1, the copper wire and aluminum wire are fixed in the corresponding copper tube 11 and aluminum tube 12 respectively, and then the aluminum tube 12 is inserted into the copper tube 11, so that a reliable transition connection between the copper wire and the aluminum wire can be achieved.

[0022] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, a protective mechanism 3 is provided on the outside of terminal 1. The protective mechanism 3 includes a first protective shell 31, a second protective shell 32, a locking block 34, and a fixing component 35. The first protective shell 31 is provided on the outside of terminal 1. The second protective shell 32 is rotatably connected to the first protective shell 31. A connecting groove 33 is provided on the side wall of the second protective shell 32. The locking block 34 is provided on the side wall of the first protective shell 31. The fixing component 35 is provided on the first protective shell 31.

[0023] The fixing component 35 includes a second spring 352 and a latch 353. The inner wall of the connecting groove 33 has a mounting hole 351. The second spring 352 is disposed in the mounting hole 351. The latch 353 is connected to the other end of the second spring 352. The outer wall of the locking block 34 has a limit hole 354.

[0024] A moisture-proof shell 4 is fitted over the first protective shell 31, and a slot 5 is provided inside the moisture-proof shell 4. Specifically, after the installation of terminal 1 is completed, terminal 1 is placed inside the first protective shell 31, and then the second protective shell 32 is fastened. At this time, the locking block 34 will be inserted into the connecting groove 33 and the locking bolt 353 will be pressed into the mounting hole 351. When the first protective shell 31 and the second protective shell 32 are closed, the limiting hole 354 on the outer wall of the locking block 34 will be aligned with the mounting hole 351 on the inner wall of the connecting groove 33. Then, the locking bolt 353 will be ejected into the limiting hole 354 under the action of the second spring 352 to complete the fixation. After the fixation is completed, the moisture-proof shell 4 is put on the outside of the shell formed by the first protective shell 31 and the second protective shell 32 to perform moisture-proof treatment.

[0025] Working principle: When using terminal 1 to transition between copper and aluminum wires, the copper and aluminum wires are fixed in the corresponding copper tube 11 and aluminum tube 12 respectively. Then, the aluminum tube 12 is inserted into the copper tube 11. At this time, the slider 26 on the outer wall of the aluminum tube 12 moves along the slide groove 21 and presses the limiting block 23. Then, the aluminum tube 12 is rotated to slide the slider 26 from the slide groove 21 into the limiting groove 24. At this time, the limiting block 23, which is no longer pressed by the slider 26, will pop out under the action of the first spring 22 and block the opening of the limiting groove 24, thereby fixing it. After the installation of terminal 1 is completed, Terminal 1 is placed inside the first protective shell 31, and then the second protective shell 32 is fastened. At this time, the locking block 34 will be inserted into the connecting groove 33 and the locking bolt 353 will be pressed into the mounting hole 351. When the first protective shell 31 and the second protective shell 32 are closed, the limiting hole 354 on the outer wall of the locking block 34 will be in the mounting hole 351. Then the locking bolt 353 will be ejected into the limiting hole 354 under the action of the second spring 352 to complete the fixation. After the fixation is completed, the moisture-proof shell 4 is put on the outside of the shell formed by the first protective shell 31 and the second protective shell 32 to perform moisture-proof treatment.
