[0027] Referring to Figures 1 to 4 , in an embodiment of the present utility model, an American - style C - type copper wiring terminal includes:

[0028] A semi - ring part 100, which is an integrally formed structure. The semi - ring part 100 is in the shape of a semi - ring with a central angle of 180 degrees. At the middle of the width direction at both ends of the length direction of the semi - ring part 100, a first hanging ear 110 and a second hanging ear 120 are respectively provided. The cross - section of the first hanging ear 110 is trapezoidal and the outer side is the bottom of the trapezoid. The second hanging ear 120 is in a plate - like structure;

[0029] The main body part 200 is an integrally formed structure. The two ends of the main body part 200 in the length direction are respectively a wiring fixing head 210 and a wire fixing cylinder 220. One end of the wiring fixing head 210 away from the wire fixing cylinder 220 is provided with a semi-circular notch 211. The central angle of the notch 211 is 180 degrees. The semi-ring part 100 is detachably combined with the notch 211. A first hanging opening 212 corresponding to the first hanging ear 110 is arranged on the notch 211. The cross section of the first hanging opening 212 is trapezoidal and the outer side is the bottom edge of the trapezoid. A second hanging opening 213 corresponding to the second hanging ear 120 is arranged on the notch 211. The second hanging opening 213 is in a plate-like structure. The second hanging ear 120 and the second hanging opening 213 form a tenon and mortise fit;

[0030] Wherein, the semi-ring part 100 and the wiring fixing head 210 are connected by friction stir welding on the end face in the width direction.

[0031] In the prior art, it is relatively difficult to process through holes on the large-sized terminal ends of wiring posts. Especially after the through holes are introduced and a wall structure with a relatively thin size is formed on the terminal ends of the wiring posts, it is somewhat difficult to process through holes on the terminal ends of the wiring posts either by machining centers or by cold heading.

[0032] The American C-type copper wiring terminal provided by the utility model includes a semi-ring part 100 and a main body part 200.

[0033] The semi-ring part 100 is an integrally formed structure. The processing method is preferably stamping, so as to achieve a relatively high processing efficiency. The semi-ring part 100 of the wiring fixing head 210 is in a semi-circular shape with a central angle of 180 degrees. The two ends of the semi-ring part 100 of the wiring fixing head 210 in the length direction are respectively provided with a first hanging ear 110 and a second hanging ear 120 in the middle of the width direction. The cross section of the first hanging ear 110 of the wiring fixing head 210 is trapezoidal and the outer side is the bottom edge of the trapezoid. The second hanging ear 120 of the wiring fixing head 210 is in a plate-like structure. The specific sizes of the first hanging ear 110 and the second hanging ear 120 are appropriately selected according to the size of the American C-type copper wiring terminal.

[0034] The main body part 200 is an integrally formed structure, and the processing method is preferably cold heading forming, so as to meet more complex outer shapes. At both ends of the main body part 200 in the length direction are a wiring fixing head 210 and a wire fixing cylinder 220 respectively. At one end of the wiring fixing head 210 away from the wire fixing cylinder 220, a semi-circular notch 211 is provided. The central angle of the notch 211 of the wiring fixing head 210 is 180 degrees. The semi-ring part 100 can be detachably combined with the notch 211 of the wiring fixing head 210. A first hanging opening 212 is provided on the notch 211 of the wiring fixing head 210 corresponding to the first hanging ear 110 of the wiring fixing head 210. The cross-section of the first hanging opening 212 of the wiring fixing head 210 is trapezoidal and the outer side is the bottom edge of the trapezoid. A second hanging opening 213 is provided on the notch 211 of the wiring fixing head 210 corresponding to the second hanging ear 120 of the wiring fixing head 210. The second hanging opening 213 of the wiring fixing head 210 is in a plate-like structure. In the process of combining the semi-ring part 100 with the main body part 200, the main body part 200 is placed vertically in the width direction, and the side with the second hanging opening 213 is at the bottom. The cross-section of the first hanging ear 110 is trapezoidal, so that the semi-ring part 100 can be hung on the first hanging opening 212 based on the first hanging ear 110. Both the second hanging ear 120 and the second hanging opening 213 are plate-like and form a tenon and mortise fit. For example, the second hanging ear 120 is in a dovetail prism structure, and the second hanging opening 213 is in a dovetail groove structure, so that a tenon and mortise fit can be formed between the two. When the semi-ring part 100 and the main body part 200 are combined, the above tenon and mortise fit restricts the separation of the semi-ring part 100 and the main body part 200 in the length direction.

[0035] After the semi-ring part 100 and the main body part 200 are initially fixed through the first hanging ear 110 and the second hanging ear 120, the semi-ring part 100 of the wiring fixing head 210 and the wiring fixing head 210 of the wiring fixing head 210 are connected by friction stir welding on the end face in the width direction. It should be particularly noted that multiple American C-type copper wiring terminals can be arranged side by side, so as to complete friction stir welding at one time. During the welding process, the American C-type copper wiring terminals can be fixed in suspension, so that welding can be completed on both the upper and lower surfaces at the same time.

[0036] In summary, it is integrally divided into a semi-circular part 100 and a main body part 200, and both can be conveniently integrally formed; the semi-circular part 100 is hung on the first hanging port 212 based on the first hanging ear 110, so that the semi-circular part 100 will not fall in the vertical direction, and the second hanging ear 120 and the second hanging port 213 form a tenon and mortise fit to limit the separation of the semi-circular part 100 and the main body part 200 in the length direction; when the semi-circular part 100 and the main body part 200 are initially fixed through the first hanging ear 110 and the second hanging ear 120, the semi-circular part 100 of the wiring fixing head 210 and the wiring fixing head 210 of the wiring fixing head 210 are connected by friction stir welding on the end face in the width direction. A plurality of American C-shaped copper wiring terminals are arranged side by side, and friction stir welding is efficiently completed at one time.

[0037] In one embodiment, the semi-circular part 100 and the wiring fixing head 210 are connected by friction stir welding on the end face in the thickness direction.

[0038] In this embodiment, the connection position between the semi-circular part 100 and the wiring fixing head 210 is increased. Specifically, the friction stir welding process is also introduced on the end face in the thickness direction of the American C-shaped copper wiring terminal to form a connection. During the implementation process, it is preferably to form a connection between the semi-circular part 100 and the wiring fixing head 210 on the end face in the width direction of the American C-shaped copper wiring terminal, and then complete the friction stir welding on the end face in the thickness direction, so as to achieve convenient operation.

[0039] Refer to Figure 4 In one embodiment, a conductive ring 300 is clamped between the semi-circular part 100 and the wiring fixing head 210.

[0040] In this embodiment, the conductive ring 300 is introduced to meet different application scenarios.

[0041] In one embodiment, the dimensions of the first hanging ear 110 and the second hanging ear 120 in the length direction of the main body part 200 are 0.1 to 0.2 times the outer diameter of the semi-circular part 100.

[0042] In this embodiment, the lengths of the first hanging ear 110 and the second hanging ear 120 are limited, which can reduce the processing difficulty while ensuring the bonding stability of the semi-circular part 100.

[0043] In one embodiment, the width dimensions of the first hanging ear 110 and the second hanging ear 120 are 0.4 to 0.6 times the width of the semi-circular part 100.

[0044] In this embodiment, the widths of the first lug 110 and the second lug 120 are restricted relative to the semi-circular portion 100, so that while the semi-circular portion 100 and the main body portion 200 are easy to process, the bonding stability between the semi-circular portion 100 and the main body portion 200 can also be ensured.

[0045] Referring to Figure 1 , in one embodiment, both ends of the wiring fixing head 210 in the width direction are flat structures.

[0046] In this embodiment, both ends of the wiring fixing head 210 in the width direction are set as flat structures, which is beneficial to friction stir welding and also beneficial to the support of the main body portion 200 based on the end faces in the width direction of the wiring fixing head 210.

[0047] In one embodiment, both the main body portion 200 and the semi-circular portion 100 are cold-heading formed.

[0048] In this embodiment, a forming method for the main body portion 200 and the semi-circular portion 100 is proposed, which has the advantages of convenience, high efficiency and high precision. Especially when the size of the American C-type copper terminal is relatively large, the advantages of cold-heading forming are obvious.

[0049] In one embodiment, the outer surface of the American C-type copper terminal is provided with a tin plating layer.

[0050] In this embodiment, a tin plating layer with a thickness of not less than 6 μm is provided on the outer surface of the American C-type copper terminal. The plating layer is uniform, with consistent color and no peeling, etc. The tin plating layer improves the outer surface quality and also forms a protection.

[0051] In one embodiment, both the semi-circular portion 100 and the main body portion 200 are made of aluminum or both are made of copper.

[0052] In this embodiment, common material selections for the semi-circular portion 100 and the main body portion 200 are given. The structural design of the present utility model is not applicable to the selection of different materials for the semi-circular portion 100 and the main body portion 200.

[0053] In summary, the American C-type copper terminal provided by the present utility model is integrally divided into a semi-circular portion 100 and a main body portion 200, and both can be conveniently integrally formed; the semi-circular portion 100 is hung on the first hanging port 212 based on the first hanging ear 110, so that the semi-circular portion 100 will not fall in the vertical direction, and the second hanging ear 120 and the second hanging port 213 form a tenon and mortise fit to limit the separation of the semi-circular portion 100 and the main body portion 200 in the length direction; when the semi-circular portion 100 and the main body portion 200 are preliminarily fixed through the first hanging ear 110 and the second hanging ear 120, the semi-circular portion 100 of the wiring fixing head 210 and the wiring fixing head 210 of the wiring fixing head 210 are connected by friction stir welding on the end surface in the width direction. A plurality of American C-type copper terminals are arranged side by side, and friction stir welding is efficiently completed at one time.

[0054] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model.
