Abstract
The utility model discloses a tin-plated copper wire, and relates to the technical improvement of a structure of the tin-plated copper wire. The tin-plated copper wire comprises a steel core wire (1), wherein six longitudinal protrusion ribs (4) are uniformly distributed on the surface of the steel core wire (1), a copper layer (2) covers outside the steel core wire (1), and a tin-plated layer (3) covers outside the copper layer (2). The tin-plated copper wire disclosed by the utility model solves the problem of high cost of the existing tin-plated copper wire. According to the utility model, the tin-plated copper wire is improved in combination so that a tin-plated copper-clad steel wire can be formed. The tin-plated copper wire is mainly applied to leads of electronic components, jumper wires of PCBs (printed circuit boards) and electronic guide pines. According to the utility model, low-carbon steel is made into the core wire, and the longitudinal protrusion ribs are arranged on the surface of the steel core wire, so that the wire can be enhanced in strength; and the copper layer is chemically electroplated and then an unleaded tin-based alloy is hot-dipped so as to prepare the product; and due to relatively low production cost, the tin-plated copper wire disclosed by the utility model is the optimal substitute of the existing tin-plated copper wire.
Description
Technical field
The utility model relates to the improvement technology of tinned wird structure.
Background technology
Existing tinned wird is take 99.99% red copper as heart yearn, forms through the hot dip kamash alloy; Product have outward appearance light, color and luster evenly, the characteristics such as tin layer strong adhesion, high antioxidant, meet " SJ2422-83 electronic devices and components tinned wird " standard; The electronic pins (lead-in wire) that now is widely used in electric wire, electronic devices and components is connected cross-line (wire jumper) with pcb board.
But there is the high shortcoming of cost in existing tinned wird.
Summary of the invention
The utility model provides a kind of tinned wird, and the utility model has solved existing tinned wird and had the high problem of cost.
For addressing the above problem, the utility model adopts following technical scheme: tinned wird, comprise steel core wire 1, and steel core wire 1 surface is evenly distributed with six vertical fins 4, and steel core wire 1 outside is surrounded by copper layer 2, and there is tin coating 3 copper layer 2 outside.
The utility model in conjunction with improving, forms CP wire with tinned wird.Be mainly used in electronic component down-lead, pcb board wire jumper, electronics guide pin.The utility model is take mild steel as heart yearn, and there is vertical fin on the steel core wire surface, has improved the intensity of line, behind electroless plating copper layer, and the product that makes of hot dipping leadless tin-base alloy again; Its production cost is relatively low, is the best substitute of existing tinned wird.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: steel core wire 1, copper layer 2, tin coating 3, vertical fin 4.
Embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, tinned wird comprises steel core wire 1, and steel core wire 1 surface is evenly distributed with six vertical fins 4, and steel core wire 1 outside is surrounded by copper layer 2, and there is tin coating 3 copper layer 2 outside.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And the apparent variation of being amplified out thus or change still are among the protection range of the present utility model.
Claims (1)
1. tinned wird, it is characterized in that, comprise steel core wire (1), steel core wire (1) surface is evenly distributed with six vertical fins (4), steel core wire (1) outside is surrounded by copper layer (2), and there is tin coating (3) copper layer (2) outside.
