Description

Technical Field

[0001] The present disclosure relates to the field of wiring harnesses, and in particular to a corrosion-resistant power wiring harness and a power cord. Background Art

[0002] The wire harness industry chain includes wires and cables, connectors, processing equipment, wire harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in automobiles, home appliances, computers, communications equipment and various electronic instruments.

[0003] The processing of power harnesses is generally to cut the wrapped harnesses into the required length, then strip the two ends of the harnesses to expose the copper wires at both ends of the harnesses, then tin the exposed copper wires at both ends, and finally crimp the exposed copper wires to the terminals to complete the assembly of the power harnesses. Among them, tinning the copper wires is mainly to prevent copper from being exposed to the air and being oxidized and corroded to form a layer of film - verdigris, which has poor conductivity and increases resistance. Tinned copper wires can prevent redox reactions from producing verdigris. However, in order to prevent the tin liquid from seeping into the protective rubber sleeve of the wiring harness, uneven tinning is likely to occur when tinning the exposed copper wires at both ends. After the terminal is crimped, there are still some exposed copper wires, that is, the exposed copper wires close to the main body of the wiring harness. Since these exposed copper wires are not tinned, the exposed copper wires of the power harness that have not been tinned are easily corroded during use. At the same time, there are gaps in the connection between the copper wire and the protective rubber sleeve, which causes corrosion to spread through the exposed area of ​​the wiring harness to the copper wire in the protective rubber sleeve, thereby affecting the conductivity of the power harness.

[0004] For example, Chinese patent document CN207542472U discloses a refrigerator waterproof power cord, including a plastic clamp and a wire, wherein the plastic clamp includes a limit portion and a main body, wherein the limit portion is convexly arranged at the end of the main body; the main body is provided with a clearance slot; the main body is provided with a first clamp ring and a second clamp ring on one side of the clearance slot facing the limit portion, a first waterproof groove is formed between the first clamp ring and the second clamp ring, and a second waterproof groove is formed between the second clamp ring and the limit portion; the main body is provided with a third clamp ring and a fourth clamp ring on the other side of the clearance slot away from the limit portion; a third waterproof groove is formed between the third clamp ring and the fourth clamp ring; the main body is provided with a through hole, and the wire is clamped in the through hole. The above refrigerator waterproof power cord forms multiple waterproof walls, and can achieve better waterproof performance after the plastic clamp is connected to the refrigerator, thereby improving the quality and service life of home appliances using the refrigerator waterproof power cord.

[0005] Although the above-mentioned refrigerator waterproof power cord has good waterproof performance, it also has the following problems: the copper wires at both ends of the power cord are exposed after being peeled, and there will be uneven tinning when the two ends of the power cord are tinned, that is, the copper wires of the exposed part close to the wiring harness body are not tinned, which causes the exposed copper wires of the power cord that are not tinned to be corroded during use, and the corrosion may spread through the exposed area of ​​the wiring harness to the copper wire in the protective rubber sleeve, affecting the conductivity of the power cord.

[0043] like Figure 1 As shown, in one embodiment, the number of the copper wires 200 is at least two, and the number of the protective rubber sleeves 100 is at least two. It can be understood that the number of the copper wires 200 is at least two, namely, the positive electrode connecting wire and the negative electrode connecting wire.

[0044] like Figure 1 As shown, in one embodiment, the number of the tinning protection components 300 is at least two, and the number of the insulating protection components 400 is at least two. It can be understood that the positions of the tinning protection components 300 and the insulating protection components 400 on the two wires are the same.

[0045] like Figure 3As shown, in one embodiment, the first tin-plated area 212 and the second tin-plated area 222 are both used for crimping terminal pieces.

[0046] like Figures 1 to 3 As shown, in one embodiment, the corrosion-resistant power harness 10 further includes a connecting rubber seat 500, the number of connecting ends of the connecting rubber seat 500 is at least two, and each connecting end of the connecting rubber seat 500 is used to connect with the terminal piece of the first tin-plated area 212 or the terminal piece of the second tin-plated area 222.

It can be understood that this can improve the sealing of the connection between the first fixed sleeve 430 and the protective rubber sleeve 100 and the sealing of the connection between the first fixed sleeve 430 and the first exposed part 210, thereby isolating the exposed copper wire 200 from contact with the air, thereby effectively avoiding the corrosion of the exposed copper wire 200, and further improving the corrosion resistance of the power harness 10.
