Description

Technical Field

[0001] The present application relates to the technical field of conductor connection, and in particular to a conductor connection structure. Background Art

[0002] In the existing conductor connection technology, two or more conductors are simply surrounded by an enclosing conductor, and the resistor of one of the conductors with an insulating layer on the surface is melted through resistance welding, ultrasonic welding or other welding methods, so that contact and conduction are generated between adjacent resistors. The contact between the two resistors is point contact or line contact, resulting in partial conduction between the two resistors, resulting in poor contact between the two. When the conductor is subjected to a large tensile force, the resistor after welding will be disconnected, causing the connection to fail and unable to conduct electricity. Summary of the invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a conductor connection structure.

[0005] at least two adjacent conductors, the conductors having a connecting portion;

[0006] A connecting body, wherein the connecting body is used to wrap the connecting part and conduct at least two adjacent conductors by welding. The connecting body includes a first metal layer, the first metal layer is deformable, a second metal layer is arranged on a side of the first metal layer close to the conductor, the melting point of the second metal layer is lower than the melting point of the first metal layer, and when the second metal layer is in a molten state, the second metal layer is immersed in at least a portion of the gap between the connecting parts.

[0007] According to the technical solution provided in the embodiment of the present application, the material of the first metal layer is copper or a copper alloy, and the material of the second metal layer is tin or lead or zinc or aluminum or a tin alloy.

[0008] According to the technical solution provided in the embodiment of the present application, the second metal layer completely covers the first metal layer; the position of the second metal layer corresponds to the position of the connecting portion.

[0009] According to the technical solution provided in the embodiment of the present application, the second metal layer partially covers the first metal layer, and the position of the second metal layer corresponds to the position of the connecting portion.

[0010] According to the technical solution provided in the embodiment of the present application, the thickness of the second metal layer is 5 μm to 30 μm.

[0011] According to the technical solution provided in the embodiment of the present application, the conductor further has an insulating portion, and the insulating portion is wrapped with a first insulating layer, and the melting point of the first insulating layer is lower than the melting point of the second metal layer.

[0012] According to the technical solution provided in the embodiment of the present application, the connection body is wrapped with a third insulating layer.

[0013] According to the technical solution provided in the embodiment of the present application, the connected conductors have the same wire diameter or different wire diameters.

[0014] According to the technical solution provided in the embodiment of the present application, the connected conductors are on the same side or different sides of the connecting portion.

[0015] A conductor connection structure, comprising:

[0016] at least two adjacent conductors, the conductors having a connecting portion;

[0017] A connecting body, wherein the connecting body is used to wrap the connecting part and conduct at least two adjacent conductors by welding.

[0019] The beneficial effects are:

[0020] Since the conductor has a connection portion, the connection portions of at least two adjacent conductors can be connected by welding, so that the adjacent conductors can be connected and conduct electricity can be achieved.

[0021] By wrapping the connecting body around the connecting parts of two adjacent conductors, the two adjacent connecting parts can be prevented from separating, thereby facilitating conduction between the two adjacent connecting parts. Since the connecting body includes a first metal layer, a second metal layer is provided on the side of the first metal layer close to the conductor, and the melting point of the second metal layer is lower than the melting point of the first metal layer, the second metal layer can be immersed in at least part of the gap of the connecting part by melting the second metal layer, so as to conduct the adjacent conductors and enable electricity between the two.

[0022] The conductor connection structure makes the connection between conductors more reliable by immersing the molten second metal layer into the gaps between adjacent connecting parts, which can avoid poor contact caused by point contact or line contact connection methods and avoid disconnection between adjacent conductors when the conductors are subjected to large pulling forces.

[0036] Example 1

[0037] Please refer to Figures 1 to 9 , this embodiment provides a conductor connection structure, including:

[0038] at least two adjacent conductors 2, each of the conductors 2 having a connecting portion;

[0039] A connecting body 1, wherein the connecting body 1 is used to wrap the connecting part and connect at least two adjacent conductors 2 by welding. The connecting body 1 includes a first metal layer 11, and the first metal layer 11 is deformable. A second metal layer 12 is arranged on one side of the first metal layer 11 close to the conductor 2. The melting point of the second metal layer 12 is lower than the melting point of the first metal layer 11. When the second metal layer 12 is in a molten state, the second metal layer 12 is immersed in at least part of the gap between the connecting parts.

[0040] Specifically, Figure 5 As shown, the second metal layer 12 may also be immersed in all gaps between the connecting parts.

[0041] Specifically, the second metal layer 12 is electroplated on the first metal layer 11 .

[0042] Furthermore, the electroplating method includes ion sputtering, chemical plating and the like.

[0043] Specifically, the connection between two adjacent conductors 2 may be a connection between a wire and a wire, a connection between a heating wire and a wire, or a connection between a fan wire and a wiring harness wire.

[0044] Working principle:

[0045] like Figure 3 As shown, when connecting two different adjacent conductors 2, the connecting parts of the two conductors 2 are first wrapped by the connecting body 1 to prevent the two connecting parts from being separated, and then the connecting body 1 is heated. Since the melting point of the first insulating layer 212 is lower than the melting point of the second metal layer 12, as shown in FIG. Figure 4-5As shown, when the two conductors 2 are subjected to pressure, the second metal layer 12 is immersed in at least part of the gap between the two different conductors 2, so that the contact-type conduction between the conductors 2 is changed to the immersion-type conduction by the second metal layer 12, so that the connection between the conductors 2 is more reliable. The conductor 2 connection structure immerses the molten second metal layer 12 in part of the gap of the connection part, so that the connection between the conductors 2 is more reliable through the immersion connection, which can avoid poor contact caused by point contact or line contact connection, and can avoid the situation where the adjacent conductors 2 are disconnected when the conductors 2 are subjected to a large pulling force.

[0052] In some other embodiments, the melting point of the first insulating layer 212 is higher than the melting point of the second metal layer 12 .

[0053] Specifically, before connecting adjacent conductors 2, the first insulating layer located at the connecting portion needs to be peeled off by welding.

[0054] In a preferred embodiment, the metal wire 211 is wrapped with a second insulating layer.

[0055] Specifically, before connecting adjacent conductors 2, the second insulating layer located at the connecting portion needs to be peeled off by welding.

[0057] Specifically, after the connection body 1 wraps the connection portion of the adjacent conductor 2 , the third insulating layer is wrapped on the connection body 1 .

[0058] Specifically, the third insulating layer is used to prevent electrical leakage at the connection portion.
