[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] like Figures 1 to 4 As shown, the utility model provides a copper-aluminum wire connection structure with good stability, including a conductive connector 1, which is made of elastic metal as a whole and has a certain elastic force, so that the wire cores 41 fixed together can conduct electricity to each other, and the left and right ends of the conductive connector 1 are provided with plug-in ports 11, and the outer surface of the conductive connector 1 is symmetrically provided with crimping portions 12, and the wire core 41 to be connected only needs to be inserted from the plug-in port 11 until the wire core 41 is squeezed by the crimping portion 12, thereby confirming that the plug-in is in place, and the upper and lower surfaces of the conductive connector 1 are symmetrically provided with second crimping portions 13, which squeeze and clamp the wire core 41 passing through the reserved hole 34, thereby ensuring power supply, and the conductive connector An insulating part 2 is provided on the circumferential outer surface of the connector 1 to isolate the conductivity of the conductive connector 1 and ensure the safety of the protective shell 3. A protective shell 3 is provided on the circumferential outer surface of the insulating part 2. End covers are provided on the left and right ends of the protective shell 3 to wrap the conductive connector 1, the insulating part 2, etc. inside to increase the protection performance. The protective shell 3 includes an arc plate 31 that is symmetrical up and down. The arc plate 31 is made of plastic and plays a basic protection role. A telescopic part 32 is provided between the arc plates 31 to change the distance between the two arc plates 31 through its own telescopic characteristics, so that it is suitable for wire cores 41 and conductive connectors 1 with different outer diameters, thereby increasing the applicability of the copper-aluminum wire connection structure and reducing procurement and production pressure.

[0025] Further, if Figure 2 As shown, the telescopic member 32 is a polyurethane telescopic plate, which has good wear resistance and impact resistance and can withstand large telescopic deformation. The outer surface of the telescopic member 32 is provided with a telescopic groove 33, which increases the surface circumference of the telescopic member 32, thereby increasing its elongation and improving the deformation capacity of the telescopic member 32.

[0026] Further, if Figure 4 As shown, a reserved hole 34 is provided in the middle of the surface of the arc plate 31 to provide room for the later wire addition needs, without the need to additionally replace the copper-aluminum wire connection structure. A decorative plate 35 is provided in the reserved hole 34, and connecting teeth 36 are evenly distributed between the reserved hole 34 and the decorative plate 35. The connecting teeth 36 are made of plastic material, which makes the contact area between the reserved hole 34 and the decorative plate 35 extremely small. Pressing the decorative plate 35 with a tool can break the connecting teeth 36. The new wire plug-in position is convenient for later wire addition.

[0027] Furthermore, the insulating member 2 is insulating rubber, and the inner circumferential surface of the insulating member 2 is provided with corrugated insulating paper, which plays a double insulation role. The corrugations increase the elasticity and reduce the damage caused by thermal expansion and contraction. The upper and lower surfaces of the insulating member 2 are symmetrically provided with No. 2 reserved holes 22, and the No. 2 reserved holes 22 overlap with the reserved holes 34.

[0028] Further, if Figure 4 As shown, a No. 2 decorative plate 23 is provided in the No. 2 reserved hole 22, and a No. 2 connecting tooth 24 is evenly distributed between the No. 2 reserved hole 22 and the No. 2 decorative plate 23. Both the No. 2 connecting tooth 24 and the No. 2 decorative plate 23 are made of plastic, which ensures insulation safety and ensures that the No. 2 connecting tooth 24 can be broken smoothly when adding wires.

[0029] Further, if Figure 3 As shown, the left and right ends of the conductive connector 1 are provided with copper-aluminum wires 4, and the copper-aluminum wires 4 are provided with a wire core 41 inside. The end of the wire core 41 close to the wire connector 1 passes through the plug-in port 11 to abut against the crimping portion 12. The crimping portion 12 is a connecting bridge for the wire core 41. During plug-in installation, it should be ensured that the wire core 41 and the crimping portion 12 are in maximum contact area.

[0030] Working process: first, remove the insulating protective shell on the outside of the copper-aluminum wire 4 to expose the wire core 41, insert the two wire cores 41 to be connected into the plug port 11, and gradually squeeze them into the crimping part 12 until the plug-in resistance becomes smaller and the plug-in is in place; at the same time, due to the insertion of the guide core 41, the conductive connector 1 moves and deforms, causing the outer diameter of the insulating part 2 to increase, thereby causing the expansion groove 33 to deform, and causing the distance between the arc plates 31 to increase; further, when there is a need to add wires, a practical tool is used to forcefully poke the decorative plate 35 and the second decorative plate 23, so that the connecting teeth 36 and the second connecting teeth 24 are broken, so that the newly added wire core 41 is inserted into the No. 2 crimping part 13 from the reserved hole 34 and the No. 2 reserved hole 22, and is squeezed and clamped, and an additional rubber ring is used to fill the gap to increase insulation safety, and the connection is completed.

[0031] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc. indicate directions or positional relationships 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, rather than indicating or implying that the equipment or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0032] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
