Description

Technical Field

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

[0002] Cable lugs (DTs) are commonly used for cable termination and splicing, ensuring a more secure and safer connection between cables and electrical components. They are a common material used in construction, electrical equipment, and electrical connections. Generally, when connecting conductors to terminals, national wiring standards require the use of corresponding terminal blocks for cable terminations. Copper lugs offer good appearance, excellent conductivity, and safety.

[0003] There are generally two ways to produce copper lugs: one is to cut off excess material from a copper rod, and the other is to stamp copper tubes. The latter is relatively easier to manufacture. When using common copper lugs, the stamped part is usually used as the bolt crimping end for fixing, and the unflattened end is connected to the cable. When connecting the cable, the cable is inserted first, and then the cable compartment is squeezed to deform it and complete the clamping and fixing connection. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide a copper tube and copper lug structure that is easy to use and has good connection strength and stable sleeve coverage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a copper tube and copper nose structure, including a wire compartment and a contact part made by stamping a whole copper tube, a cut-out part is provided in the area between the wire compartment and the contact part, an anti-slip part is provided on the outer surface of the wire compartment, and a heat shrink tubing is provided on the outer sleeve of the wire compartment, the anti-slip part is used to restrict the heat shrink tubing from coming off outward.

[0006] As a further feature of the above solution, the cut-out portion is located in the buffer portion between the wire housing and the contact portion, and the inner hole of the wire housing is polished by a scraper and has a solder layer.

[0007] As a further feature of the above solution, the anti-slip part includes a groove and a rocker arm, the rocker arm being hinged and swinging relative to the outer wall of the cable compartment.

[0008] As a further feature of the above solution, the contact portion is also provided with a fixing hole and a marking area, wherein the fixing hole is used for the passage of the fixing bolt.

[0009] As a further feature of the above solution, the contact portion is formed by stamping the two side walls of the copper tube towards the center. The contact portion is located in the middle part of the relative wire compartment, and the ratio of the distance between the two end faces of the contact portion and the maximum outer edge of the wire compartment is approximately 1:3.

[0010] As a further feature of the above solution, the cut-out portion and the anti-slip portion are formed by stamping.

[0011] Beneficial effects: The copper tube lug of this utility model has a cut in the buffer part located between the end of the cable compartment and the contact part, which allows solder to be introduced to fix the cable to the cable compartment during cable connection. There is also an anti-slip part on the outside of the cable compartment. After the cable is fixed, the connection seam is covered by heat shrink tubing. The anti-slip part has a rocker plate that forms a limit in the opposite direction, which can improve the covering strength of the heat shrink tubing, prevent axial loosening, and facilitate the use of the copper lug.

[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 Figure 1-2 The copper tube and copper lug structure shown in this embodiment includes a wire compartment 1 and a contact portion 2, which are made by stamping a single copper tube. Figure 1As shown, after the contact part 2 is stamped, it still needs to be shaped, including stamping to remove the waste material 10 at the edge and processing the fixing hole 6. It is worth noting that, considering the usage requirements, the copper lug in this embodiment has its inner hole of the copper tube polished with a scraper and a solder layer 8 is provided before stamping the contact part 2. The processing of the solder layer 8 includes, but is not limited to, processes such as spraying tin and dipping tin. Its purpose is to improve the electrical connection between the cable and the inner wall of the cable compartment 1 of the finished product and to improve the connection strength achieved by pouring tin into the cut part 3. As mentioned above, in order to facilitate the stamping process and the subsequent solder pouring, this embodiment provides a cut part 3 in the area between the cable compartment 1 and the contact part 2, and further provides an anti-slip part 4 on the outer surface of the cable compartment 1. In use, after the cable connection is completed according to the prior art, a heat shrink tubing 5 is put on the cable compartment 1 to cover the connection gap between the cable and the cable compartment 1. In the solution of this embodiment, the... An anti-slip part 4 is provided on the outer surface of the cable compartment 1. The anti-slip part 4 is formed by cutting a notch on the surface of the cable compartment 1 and then applying a radial punching force to misalign and punch a local material on the surface of the cable compartment 1 to form a rocker plate 42. The rocker plate 42 is not horizontal with the axial direction of the cable compartment 1 and swings outward relative to the contact part 2 at the rear of the cable compartment 1. When the cable compartment 1 is flattened, the rocker plate 42 is misaligned with the groove 41. When not flattened, it acts like a barb. Under the flattening force, a protrusion is formed on the surface of the cable compartment 1 where there is no groove 41. When the heat shrink tubing 5 is wrapped, the groove 41 and the protrusion formed by the rocker plate 42 provide a structure for the heat shrink tubing 5 to restrict its outward detachment. That is, when the copper lug of this embodiment is used, it can be connected to the metal end of the cable and the cable compartment 1 by soldering as a filler, or the cable can be fixed by flattening the cable compartment 1. Furthermore, the copper lug of this embodiment can also satisfy both at the same time: soldering + flattening and then wrapping with heat shrink tubing 5.

[0017] As a further provision of the above solution, the cutout 3 is located in the buffer portion 9 between the thread compartment 1 and the contact portion 2, such as... Figure 1 The purpose of the cut-out portion 3 in the buffer section 9 shown is to cut off the material in the middle of the copper tube and break its deformation stretching during the stamping process, so as to avoid large deformation at the rear end of the wire compartment 1. The cut-out portion 3 can reduce the deformation width of the buffer section 9 and reduce the waste of material in the buffer section 9.

[0018] As a further feature of the above solution, the anti-slip part 4 includes a groove 41 and a rocker 42, the rocker 42 being hinged and swinging relative to the outer wall of the wire compartment 1.

[0019] As a further provision of the above solution, the contact part 2 is also provided with a fixing hole 6 and a marking area 7. The fixing hole 6 is used for the through-hole of the fixing bolt and for the fixing installation of the bolt. In this embodiment, the copper lug is provided with a marking area 7 mainly because the user needs a space and position for attaching a label.

[0020] As a further provision of the above scheme, the contact portion 2 is formed by stamping the two side walls of the copper tube towards the center. The contact portion 2 is located in the middle part relative to the wire compartment 1, and the ratio of the distance between the two end faces of the contact portion 2 and the maximum outer edge of the wire compartment 1 is approximately 1:3. (Refer to...) Figure 2 It is worth noting that, in this embodiment, the stamping center of the contact portion 2 is not located in the middle or on either side of the copper tube. This approximate location is situated slightly below the distal end of the cut portion 3 and at a certain distance from the edge of the wire compartment 1. Firstly, this facilitates the stamping and flattening process. Secondly, the contact portion 2 formed at the edge provides a buffer for the copper tube wall on the other side, which is easily damaged by stretching. Thirdly, the purpose of not placing it in the middle is that if the cut portion were located on only one side in the middle, it would easily lead to different degrees of deformation on both sides. Figure 2 The position shown allows the tensile deformation on both sides to be relatively close based on the presence of the cutout 3.

[0021] As a further provision of the above solution, the cut portion 3 and the anti-slip portion 4 are formed by stamping process. In this embodiment, the cut portion 3 is formed by radial stamping and cutting of raw material in copper tube state, while the anti-slip portion 4 is formed by first cutting a groove in the circumference and then stamping and shearing to form the rocker plate 42 structure.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
