In this embodiment, the section of the structure where the first distance of the metal wire core 10 is located is generally used for electrically connecting with the PCB, that is, the portion of the end (the first end 10a) closer to the first bulge loop 11 is used for passing through the soldering hole and the like on the corresponding PCB. During specific use, insert the connecting wire in the welding hole of PCB circuit board, utilize first bulge loop 11 to block the connecting wire in the corresponding hole position of circuit board or on the hole position conveniently, prevent that the connecting wire from sliding wantonly to can conveniently fix the connecting wire on PCB circuit board, realize the electricity with PCB circuit board and be connected.

In this embodiment, a section of the metal core 10 corresponding to the first distance may be referred to as a first lead (not labeled), and a section of the metal core 10 corresponding to the second distance may be referred to as a second lead (not labeled). At this time, for the metal wire core 10, the first pin and the second pin are separated by the first convex ring 11, and in the process of fixing with the PCB, the first pin is electrically connected and fixed with the PCB, and the first convex ring 11 is used for clamping and limiting, for example, the first convex ring 11 is used for abutting against a conductive welding hole of the PCB, so that the first pin and the PCB are welded together in the following process. And the second pin is used for being electrically connected with other structures, so that the function of electrically connecting the connecting wire is realized.

It should be noted that, in other embodiments, an insulating material may be further sleeved on the second pin, i.e., a part of the second pin is surrounded (wrapped) by the insulating material. The respective insulating material may be as close as possible to the first collar 11 or may be directly adjacent to the first collar 11.

Fig. 1 shows that, in the present embodiment, the first projecting ring 11 has a rounded rectangle shape in side view (a shape in which a pair of parallel sides of the rectangle are circular arcs). The round rectangle makes the first convex ring 11 regular in structure, which is beneficial to the industrial use of the connecting line of the embodiment.

Therefore, the structural characteristics of the connecting wire are implemented, so that the operation of cutting the insulating skin is not needed, the corresponding damage to the metal wire core 10 in the connecting wire caused by the process of cutting the insulating skin can be avoided, the whole connecting wire is not easy to break when being bent, and the reliability of the connecting wire is improved. Meanwhile, the structure of the connecting wire also means that the processing cost can be lower, and the processing period can be shorter, so that the economic benefit of the connecting wire product can be improved from multiple aspects.

In this embodiment, the metal core 70 and the first protrusion 71 are integrally formed. Such an integrally formed structure may be formed using a corresponding integrally forming method. The integral molding method is a process which can form the required geometric structure and size. For example, the effect of different methods can be different by using extrusion molding (directly using metal wires to form the connecting wires of the embodiment through an automatic shaping machine) or by using flattening molding. The material of the metal wire core 70 and the material of the first protrusion 71 are the same, which determines that the connection wire provided in this embodiment can be manufactured by an integral molding method. That is to say, in the connection line structure provided by this embodiment, since the structure materials of the portions included in the connection line structure are the same, the connection line structure can be manufactured more easily, and the manufacturing time and cost are saved more.

Moreover, the connecting wire of the embodiment has the advantages that the reliability of the application of the connecting wire is enhanced due to the structural characteristics, and the manufacturing cost of the connecting wire product of the embodiment is greatly reduced due to the integral forming and processing. Simultaneously, can see, the connecting wire of this embodiment no longer needs the insulating skin, and this electric conductive property that has not only guaranteed the connecting wire is good, still saves the manufacturing procedure of processing the metal wire into banding insulating skin power cord, has saved the raw materials cost of an insulating layer to make the cost of manufacture of whole connecting wire product reduce once more, be favorable to improving the market competitiveness of connecting wire product greatly, for the production side of connecting wire, provide considerable economic benefits.

In this embodiment, the wire diameter of the metal wire core 70 may be between 0.3mm and 0.8mm, and may be selected according to specific requirements, such as 0.4mm, 0.5mm, 0.6mm, or 0.8 mm.

As can be seen from the above description, the connection wire provided in this embodiment does not need a corresponding insulation sheath structure covering the metal wire core 70, but has a corresponding first protrusion 71 structure, and the first protrusion 71 is used to replace the insulation sheath of the existing connection wire, so as to achieve the purpose of limiting (positioning). Therefore, the structural characteristics of the connecting wire are realized, so that the operation of cutting the insulating skin is not needed, the corresponding damage to the metal wire core 70 in the connecting wire caused by the process of cutting the insulating skin can be avoided, the whole connecting wire is not easy to break when being bent, and the reliability of the connecting wire is improved. Meanwhile, the structure of the connecting wire also means that the processing cost can be lower, and the processing period can be shorter, so that the economic benefit of the connecting wire product can be improved from multiple aspects.
