Description

Technical Field

[0001] This utility model relates to the field of copper lug technology, specifically to a copper tube terminal. Background Technology

[0002] Cable lugs, also known as cable terminals or copper lugs, are primarily made of copper materials such as copper. They are commonly used for cable termination and splicing, ensuring a stronger and safer connection between cables and electrical components. They are very common connection parts in cable installation. Common copper lug manufacturing methods include at least two types: copper tube stamping and copper rod cutting. A typical copper lug includes a cable housing and a nose wing. The nose wing is mainly used for connection to the terminal block, while the cable housing is used for securing the cable. The cable housing is typically secured to the cable by applying external pressure, causing it to collapse inwards. This increases friction and secures the cable within the housing. This is the most conventional installation method. However, this method is prone to cable detachment due to excessive external force or insufficient clamping. Therefore, current technology addresses this issue by increasing the surface roughness of the cable housing to enhance the clamping force under clamping pressure. Utility Model Content

[0003] In view of the prior art, the purpose of this utility model is to provide a copper tube copper lug terminal design, which sets up a double clamping cable structure and a docking structure to improve installation stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a copper tube terminal, including a wire spool and a nose wing terminal, the end of the wire spool is connected to the nose wing terminal, the nose wing terminal is also provided with a mounting hole, a slot and a locking block, the mounting hole is located in the middle of the slot and the locking block, and the center of the hole is set with the same distance relative to the slot and the locking block, the slot and the locking block are matched and locked together.

[0005] As a further feature of the above solution, a linkage bolt is also included. The linkage bolt is used to lock and fix the two mounting holes when the two nose wing terminals are overlapped and the slot and the block part are engaged relative to each other.

[0006] As a further feature of the above solution, the spool is also provided with a clamping part and a radial screw hole, and the radial screw hole is provided with a fastening screw for fixing the metal end of the cable.

[0007] As a further provision of the above solution, there are two clamping parts, and the radial screw hole is located in the middle of the two clamping parts.

[0008] As a further feature of the above solution, the card block is located on the mounting side of the nose wing terminal, and the spatial dimension of the mounting side is larger than the thickness dimension of the nose wing terminal.

[0009] Beneficial effects: The copper lug terminal of this utility model connects two copper lugs in use and forms an intermediate connection terminal with the external heat-shrinkable insulating sleeve, increasing its functionality. The design of the slot, the locking block and the matching structure prevents rotation after connection. In addition, the radial screws on the cable tray, together with the wire clamps, compress the copper tube, doubly securing the cable and improving connection stability. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figures 1-4 The copper tube terminal shown includes a wire spool 1 and a nose terminal 2. The end of the wire spool 1 is connected to the nose terminal 2. The nose terminal 2 is also provided with a mounting hole 21, a slot 22 and a locking block 23. The mounting hole 21 is located in the middle of the slot 22 and the locking block 23, and the center of the hole is set with the same distance from the slot 22 and the locking block 23. The slot 22 and the locking block 23 are matched in size and engaged.

[0017] As a further feature of the above solution, a linkage bolt 3 is also included. The linkage bolt 3 is used to lock and fix the two mounting holes 21 when the two nose wing terminals 2 are overlapped and the slot 22 and the block portion 23 are engaged relative to each other.

[0018] As a further provision of the above scheme, the cable drum 1 is also provided with a clamping part 11 and a radial screw hole 12, and the radial screw hole 12 is provided with a fastening screw 13 for fixing the metal end of the cable.

[0021] like Figure 1 The copper tube terminal structure of this embodiment of the present invention shown comprises a wire spool 1 and a nose terminal 2. Unlike conventional copper lugs, the wire spool 1 in this embodiment has radial screw holes 12, which can lock the inserted cable in place with fastening screws 13. Figure 4 As shown, clamping the spool 1 with pressure clamps creates a stronger fastening force, improving practical stability. Furthermore, as... Figure 2 As shown, the nose wing terminal 2 in this embodiment has a structure with a locking block 23 and a locking slot 22. Through the arrangement of the two, as Figure 3 As shown, the nose terminals 2 of two copper tube terminals can be connected to form an intermediate connection terminal, thereby improving the functionality of the copper tube terminals.
