[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0024] Reference example Figures 1 to 4 A copper terminal block includes a copper end 1 and an end body 2. The copper end 1 is provided with a rotatable ring 3, the ring 3 is provided with a spring 4, and acts on the copper end 1. Support portions 31 are provided on both sides of the end surface of the ring 3. One end of the end body 2 is provided with a connecting portion 21, the connecting portion 21 is hinged to the supporting portion 31, a spring 4 washer is provided between the connecting portion 21 and the supporting portion 31, and the supporting portion 31 is provided with a fastener 6, which passes through the connecting portion 21;

[0025] It is worth mentioning that the other end face of the ring 3 is provided with a first cylinder 32, the end face of the first cylinder 32 is provided with a second cylinder 33, the second cylinder 33 is provided with a blind hole 34, the first cylinder 32 is used in conjunction with the through hole 14, and the second cylinder 33 is used in conjunction with the cavity 13;

[0026] It is worth mentioning that the copper end 1 is provided with a mounting hole 11, the copper end 1 is provided with an extension 12, the extension 12 is provided with a cavity 13 for accommodating the second cylinder 33, the end surface of the cavity 13 is provided with a through hole 14 for the first cylinder 32 to pass through, the through hole 14 and the cavity 13 are provided with a notch 15, the notch 15 is provided with a plug 7, the first cylinder 32 prevents the ring 3 from escaping from the extension 12, the notch 15 facilitates the first cylinder 32 and the second cylinder 33 to enter the through hole 14 and the cavity 13 respectively, and the plug 7 prevents the first cylinder 32 and the second cylinder 33 from escaping from the through hole 14 and the cavity 13;

[0027] It is worth mentioning that the spring 4 is arranged in the blind hole 34 and abuts the end surface of the cavity 13. The spring 4 releases elastic force to the ring 3, so that the ring 3 is pressed tightly against the end surface of the cavity 13, increasing the friction between the ring 3 and the cavity 13, so that a damping feeling is generated when the ring 3 rotates, thereby fixing the ring 3 in the position after rotation;

[0028] It is worth mentioning that the end body 2 is provided with a cavity 22 for the exposed part of the cable. The exposed part of the cable is placed in the cavity 22 and the exposed part is pressed tightly into the end body 2 using a tool.

[0029] It is worth mentioning that the fastener 6 is configured as a bolt, and a nut 61 is provided at the end of the bolt for fixing the end body 2 in the position after the rotation.

[0030] The operating principle of the present invention is now described as follows:

[0031] The copper terminal 1 is fixed to the terminal block of the electrical equipment. When the bending angle of the cable needs to be changed, it is only necessary to loosen the fastener 6 first and adjust the angle between the terminal body 2 and the copper terminal to avoid excessive bending of the cable. After the adjustment is completed, tighten the nut 61 to fix the terminal body 2 in the adjusted position.

[0032] By pushing the end body 2, the pushing force is made greater than the elastic force of the spring 4 acting on the cavity 13, thereby changing the position of the cable with the through hole 14 as the axis, which facilitates the cable routing.

[0033] The above design solution can make the product have the advantages of being bendable and easy to route.
