Detailed Embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] A composite stranded copper wire, as Figures 1 - 5As shown in the figure, it includes a main body 1. Inside the main body 1, several cores 3 are fixedly installed. Inside the main body 1 and at the position between several cores 3, a central reinforcing body 10 is fixedly installed. A buffer mechanism is arranged between the inner wall of the main body 1 and several cores 3. An outer protective sleeve 2 and an outer protective sleeve 20 are sleeved outside the main body 1. Connection mechanisms are arranged between both ends of the outer protective sleeve 2 and the outer protective sleeve 20. The buffer mechanism includes several reinforcing layers 4 and several movable grooves 12. Several reinforcing layers 4 are all fixedly installed at the position between the inner wall of the main body 1 and several cores 3, and one end of the reinforcing layer 4 is fixedly connected to the central reinforcing body 10. Several movable grooves 12 are all opened at the position of the inner wall of the main body 1. A filling body 5 is filled inside several reinforcing layers 4. A support block 11 is fixedly installed between two reinforcing layers 4.

[0028] Inside several movable grooves 12, buffer plates 13 are fixedly installed. Between the buffer plates 13 and the inner wall of the movable grooves 12 and between the buffer plates 13 and the outer wall of the reinforcing layers 4, several elastic sheets 14 and elastic frames 15 are fixedly connected. Several elastic sheets 14 and elastic frames 15 are evenly distributed, and the elastic sheets 14 are inserted inside the elastic frames 15. The cross-section of the buffer plate 13 is arc-shaped and is made of elastic metal material, and it has good resilience with the elastic sheets 14 and the elastic frames 15.

[0029] When in use, the central reinforcing body 10 is used to integrally support and reinforce between the three cores 3. And through each reinforcing layer 4, filling body 5 and support block 11, the cores 3 and the inner wall of the main body 1 can be well supported and reinforced. At the same time, when the composite stranded copper wire receives an external impact force, the impact force acts on the main body 1 and is blocked by the outer protective sleeve 2 and the outer protective sleeve 20 to avoid directly contacting the main body 1 and causing damage to the main body 1. At the same time, the impact force causes the main body 1 to deform and sink, causing each elastic sheet 14 and elastic frame 15 to deform, and at the same time the reinforcing layer 4 also deforms. Each elastic sheet 14, elastic frame 15 and reinforcing layer 4 form a double buffer layer. Under the action of the elastic force of each elastic sheet 14, elastic frame 15 and reinforcing layer 4, the sunken part of the main body 1 can be driven to return to the initial state, so as to well buffer the external impact force. Through the above operations, the position between the inside of the main body 1 and the cores 3 can be well supported and protected, avoiding the displacement of the cores 3 and affecting normal use, and can buffer the external impact force to avoid damage to the cores 3 and affecting the service life.

[0030] As Figure 1 、 Figure 4 and Figure 5 shown in the figure, the connection mechanism includes a connecting strip 6 and a connecting strip 7. The connecting strip 6 is fixedly connected to one end of the outer protective sleeve 2. The connecting strip 7 is fixedly connected to one end of the outer protective sleeve 20. An insertion plate 19 is inserted inside the connecting strip 6, and one end of the insertion plate 19 is fixedly connected to the connecting strip 7.

[0031] A plurality of transverse grooves are formed on the upper surface of the insertion plate 19. A clamping block 18 is inserted into the transverse groove. A return spring is installed at the bottom end of the clamping block 18 and the bottom end inside the transverse groove. A plurality of clamping slots 17 are formed through the upper surface of the first connecting strip 6, and the clamping slots 17 are fitted with the clamping block 18. When the insertion plate 19 is inserted into the first connecting strip 6, the clamping block 18 moves along with the insertion plate 19. Its inclined surface first contacts the inner wall of the first connecting strip 6 and gradually contracts into the transverse groove. The return spring is compressed. When it moves to a position directly below the clamping slot 17, under the action of the elastic force of the return spring, it can be clamped into the clamping slot 17 to fix and limit the position between the first connecting strip 6 and the insertion plate 19.

[0032] A plurality of fixing grooves 9 are formed through the outer side walls of the first protective sleeve 2 and the second protective sleeve 20 near both ends. A limiting block 8 is inserted into each of the plurality of fixing grooves 9, and one end of the limiting block 8 is fixedly connected to the main body 1. When the first protective sleeve 2 is sleeved on the outside of the main body 1, the fixing grooves 9 are correspondingly sleeved on the outside of the limiting blocks 8 at the same time, which can assist the first protective sleeve 2 to be accurately sleeved on the outside of the main body 1. Similarly, the second protective sleeve 20 can be accurately sleeved on the outside of the main body 1.

[0033] Specifically, when the outer walls of the first protective sleeve 2 and the second protective sleeve 20 are damaged, the second protective sleeve 20 can be moved away from the first protective sleeve 2, driving the second connecting strip 7 away from the first connecting strip 6, so that the insertion plate 19 is removed from the first connecting strip 6. During this process, the clamping block 18 moves along with the insertion plate 19. The inclined surface of the clamping block 18 moves along the inner wall of the clamping slot 17 and gradually contracts into the transverse groove. The return spring is compressed, so as to release the fixed limit between the first connecting strip 6 and the insertion plate 19, and thus the first protective sleeve 2 and the second protective sleeve 20 can be separated, so that the first protective sleeve 2 and the second protective sleeve 20 can be removed from the main body 1. Similarly, another set of the first protective sleeve 2 and the second protective sleeve 20 is sleeved on the main body 1. Similarly, through the cooperation of the clamping block 18 and the elastic force of the return spring, the position between the insertion plate 19 and the first connecting strip 6 can be fixed, so as to fix the position between the first connecting strip 6 and the second connecting strip 7, and complete the fixation of the first protective sleeve 2 and the second protective sleeve 20. Through the above operations, it is convenient for the staff to replace the damaged first protective sleeve 2 and the second protective sleeve 20, without replacing the entire composite stranded copper wire, saving resources.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
