Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

The first embodiment of the present invention relates to a conductive wire material, as shown in fig. 1, including: a conductor 2 coated with a tin layer 1, and an insulating layer 3 covering the conductor 2. Any part of the insulating layer 3 can be peeled off from the conductor 2, and the peeled part 31 of the insulating layer 3 is constituted.

After the peeling of any portion of the insulating layer 3, the tin layer 2 on the conductor 3 is exposed from the peeled portion 31 to the peeled portion 31.

It can be seen from the above that, since the conductive body 2 of the conductive wire has the tin layer 1, when any part of the insulating layer 3 of the conductive wire is stripped, the part of the tin layer 1 on the conductive body 2 corresponding to the stripped part 31 can be directly exposed from the stripped part 31, so that in the process of welding the conductive wire on the circuit board, the operation step of manual tin immersion can be omitted, the soldering connection with the circuit board can be directly realized through the tin layer 1 on the conductive body 2, and the soldering efficiency of the product can be improved while the soldering quality is ensured.

Specifically, in the present embodiment, as shown in fig. 1, the peeling portion 31 is located at an end portion of the conductive wire material of the present embodiment. That is, in the present embodiment, the two ends of the insulating layer 3 are the peeling portions 31, respectively. Meanwhile, in order to facilitate the partial peeling of the insulating layer 3, the inner conductor 2 is prevented from being broken when the insulating layer 3 is peeled. The insulating layer 3 is also provided with at least one removable crease line, so that the insulating layer 3 can be removed along the crease line when the insulating layer 3 is removed, and the acting force when the insulating layer 3 is removed can be concentrated on the crease line, thereby avoiding influencing the conductor 2.

In the present embodiment, the fold line is previously stamped on the insulating layer 3 according to the length of the portion to be welded of the conductive wire. So that the operator can peel off the insulating layer 3 directly by means of the crease line in actual use. Meanwhile, in order to facilitate partial peeling of the insulating layer 3, a rubber layer is used as the insulating layer 3 in the present embodiment. Of course, in the practical application process, the insulating layer 3 may also be a plastic or silicone layer, and in the present embodiment, the kind of the insulating layer 3 is not specifically limited.

Note that, in the present embodiment, as shown in fig. 2, the conductor 2 is formed by twisting a plurality of metal wires 21. The tin layer 3 may be applied to the outer surface of the conductor 2 after the metal wires 21 are twisted, or the tin layer 3 may be applied directly to the outer surface of the metal wires 21, and then twisted after the metal wires 21 are applied to form the conductor 2. In both modes, the current conductive body of the embodiment can be provided with the tin layer 3, and an operator can select a corresponding conductive wire as a wire for welding according to specific process requirements.

In the present embodiment, each of the metal wires 21 in the conductor 2 is a copper wire. Alternatively, as shown in fig. 3, some of the metal wires are copper wires 21A, and some of the metal wires are steel wires 21B, so that the conductor 2 of the present embodiment is a copper cylinder stranded body, and the strength of the entire conductor 2 can be improved by the steel wires 21B without affecting the electrical conductivity of the conductor 2.

In addition, when the conductor 2 of the conductive wire of the present embodiment is a copper-steel strand, the conductor 1 may be formed by twisting the copper wires 21A together to form a copper wire strand, then twisting the steel wires 21B together to form a steel wire strand, and at the same time, the steel wire strand is covered with the copper wire strand to form a metal protective layer, so that the conductive wire of the present embodiment can further prevent the copper wire strand from being broken by the steel wire strand when being bent.

The utility model discloses a second embodiment relates to a circuit board, include: the conductive wire as described above.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
