A connection socket is connected to the middle of the inner side of the connection sleeve, and a conductive plug is connected to the inner side of the connection tube head corresponding to the connection socket.

[0007] The connecting sleeve has a limiting side groove at an equal angle on its side end. An elastic plate is embedded in the inner side of the limiting side groove. An irregularly shaped snap-fit ​​block is connected to the inner side of the end of the elastic plate. A guide groove is provided on the side end of the connecting tube head corresponding to the limiting side groove. A limiting snap-fit ​​groove is provided on the side end of the connecting tube head at the end of the guide groove.

[0008] Preferably, when the first connecting end and the second connecting end are connected, the conductive plug at the end of the first connecting end is inserted into the connecting socket at the end of the second connecting end, and the connecting socket and the conductive plug are respectively connected to the copper core conductors of the two copper core cables that need to be connected.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-6 As shown, this utility model provides a technical solution, a copper core cable that is easy to connect, including a copper core conductor 1, three sets of copper core conductors 1 arranged in a centrally symmetrical manner, and the outer side of the three sets of copper core conductors 1 is covered with an inner insulation layer 2, the inner insulation layer 2 is ethylene propylene rubber, the outer side of the inner insulation layer 2 is covered with an isolation layer 3, the isolation layer 3 is neoprene rubber, and the outer side of the isolation layer 3 is tightly covered with an outer sheath 4, the outer sheath 4 is made of polyethylene.

[0030] The copper core cable, composed of three sets of copper core conductors 1, is connected by a connection structure. This connection structure includes a first connecting end 5 and a second connecting end 6. The first connecting end 5 and the second connecting end 6 are located at the ends of two connecting segments of the copper core cable, respectively. Both the first connecting end 5 and the second connecting end 6 are fitted with a covering sleeve 7 at their outer positions outside the outer sheath 4. A connecting sleeve 8 is fixedly connected to the end of the first connecting end 5, and a connecting tube head 9 is fixedly connected to the end of the second connecting end 6. A connecting socket 10 is connected to the middle of the inner side of the connecting sleeve 8. A conductive plug 11 is connected to the inner side of the connector 9 corresponding to the connector 10. When the first connector 5 and the second connector 6 are connected, the conductive plug 11 at the end of the first connector 5 is inserted into the connector 10 at the end of the second connector 6. The connector 10 and the conductive plug 11 are respectively connected to the copper core conductors 1 of the two copper core cables that need to be connected. By inserting the connector 9 into the connector sleeve 8, the connector 10 and the conductive plug 11 can be quickly and conveniently connected, which improves the convenience of the cable in actual connection.

[0031] A limiting side groove 12 is formed at an equal angle on the edge of the connecting sleeve 8. An elastic plate 13 is embedded in the inner side of the limiting side groove 12. A shaped snap-fit ​​block 14 is connected to the inner side of the end of the elastic plate 13. A guide groove 15 is formed on the edge of the connecting pipe head 9 corresponding to the limiting side groove 12. A limiting snap-fit ​​groove 16 is formed on the edge of the connecting pipe head 9 at the end of the guide groove 15. When the connecting sleeve 8 and the connecting pipe head 9 are connected, the shaped snap-fit ​​block 14 is snapped into the limiting snap-fit ​​groove 16 along the guide groove 15. The shaped snap-fit ​​block 14 is tightly snapped into the limiting snap-fit ​​groove 16 by the elastic support of the elastic plate 13. The elastic support of the elastic plate 13 enables the shaped snap-fit ​​block 14 to be snapped into the limiting snap-fit ​​groove 16 quickly, ensuring that the ends of the two copper core cables have higher connection stability after combination connection.

[0032] A fitting cavity 17 is provided between the inner side of the connecting sleeve 8 and the connecting socket 10. A concave airbag 18 is fixedly bonded to one side of the fitting cavity 17. A compression protrusion ring 19 is provided at the end of the connecting tube head 9 corresponding to the concave airbag 18. A recessed groove is formed on the inner side of the concave airbag 18. After the connecting tube head 9 is fully inserted into the fitting cavity 17, the compression protrusion ring 19 at the end of the connecting tube head 9 is placed in the recessed groove by the covering effect of the concave airbag 18. The deformation of the concave airbag 18 covers the compression protrusion ring 19 at the end of the connecting tube head 9, thereby enabling the connecting tube head 9 and the connecting sleeve 8 to have a higher sealing performance after connection.

[0033] Four sets of mating plates 20 are connected at equal angles to the end of the connecting sleeve 8, and a locking hole 21 is opened through the inside of the mating plate 20. The end of the first connecting end 5 is provided with a mating groove 22 corresponding to the mating plate 20, and a locking bolt 23 is connected to the edge of the first connecting end 5. After the first connecting end 5 and the second connecting end 6 are combined and connected, the mating plate 20 is inserted into the mating groove 22, and the locking bolt 23 passes through the edge of the first connecting end 5 and connects to the locking hole 21 inside the mating plate 20. This facilitates the limiting connection between the first connecting end 5 and the second connecting end 6, thereby further ensuring the tightness of the copper core cable after connection and preventing accidental loosening at the connection point.

[0034] The working principle and usage process of this utility model: In practical applications, the copper core cable that is easy to connect firstly has an inner insulation layer 2, an isolation layer 3 and an outer sheath 4 that are layered around the outside of the copper core conductor 1, which makes the copper core cable have higher practical performance. When it is necessary to combine and connect two sections of copper core cable, the first connecting end 5 and the second connecting end 6 are used to facilitate the connection between the two sections of cable. With the help of the connecting sleeve 8, the connecting tube head 9, the connecting socket 10 and the conductive plug 11, when the first connecting end 5 and the second connecting end 6 are connected, the connecting tube head 9 can be inserted into the connecting sleeve 8, so that the connecting socket 10 and the conductive plug 11 can be quickly connected to conduct electricity, thereby improving the convenience of the cable in actual connection.

[0035] Furthermore, when the connecting tube head 9 is inserted into the connecting sleeve 8, the elastic plate 13 deflects within the limiting side groove 12. The elastic plate 13 drives the irregularly shaped snap-fit ​​block 14 to slide along the guide groove 15. When the irregularly shaped snap-fit ​​block 14 moves to the limiting snap-fit ​​groove 16, the elastic support force of the elastic plate 13 enables the irregularly shaped snap-fit ​​block 14 to quickly snap into the limiting snap-fit ​​groove 16. The hooking and snapping action between the irregularly shaped snap-fit ​​block 14 and the limiting snap-fit ​​groove 16 completes the limiting between the connecting tube head 9 and the connecting sleeve 8, ensuring that the ends of the two copper core cables have higher connection stability after being combined and connected.

[0036] Meanwhile, when the connecting tube head 9 is inserted into the mating cavity 17 between the connecting sleeve 8 and the connecting socket 10, the concave airbag pad 18 provided at the inner end of the mating cavity 17 allows the compression protrusion ring 19 at the end of the connecting tube head 9 to compress the concave airbag pad 18 through the compression action, thereby deforming the concave airbag pad 18. The deformation of the concave airbag pad 18 covers the compression protrusion ring 19 at the end of the connecting tube head 9, thereby giving the connecting tube head 9 and the connecting sleeve 8 a higher sealing performance after connection, preventing the infiltration of moisture and dust.

[0037] Finally, after the first connecting end 5 and the second connecting end 6 of the two copper core cables are completely and tightly connected, the mating plate 20 at the end of the connecting sleeve 8 will engage with the locking hole 21 on the side of the first connecting end 5. Combined with the locking bolt 23 on the side of the first connecting end 5, the locking bolt 23 will be screwed into the locking hole 21 within the mating plate 20.

[0038] The locking action of the locking bolt 23 limits the connection between the first connecting end 5 and the second connecting end 6, thereby further ensuring the tightness of the copper core cable after connection and playing a safety role in preventing accidental loosening at the connection point.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
