Abstract
The utility model discloses an enameled wire used for signal transmission. The enameled wire comprises at least two parallelly placed metal wire cores whose outer surfaces are respectively coated with an insulating layer; the metal cores are composed of aluminum wire cores and copper layers coated on the outer surfaces of the aluminum wire cores; an alcohol soluble self adhesive layers is coated at the outer surfaces of the at least two metal wire cores; an aluminum copper alloy layer is arranged between the aluminum wire cores and the copper layers; the insulating layer is composed of a polyester layer and a polyurethane layer coated on the outer surface of the polyester layer; and provided are three or four metal wire cores which are parallelly arranged respectively. The enameled wire of the utility model is solidified into one integrated entity through the alcohol soluble self adhesive layer, thereby enabling favorable integrated performance; the enameled wire can transmit various kinds of signals, facilitate distinguishing the number of phases, and ensure that no delamination exists between the copper layers and the aluminum wire cores, thereby ensuring that flexibility, malleability, and tensile performance of the enameled wire are in preferable states.
Description
Technical field
The utility model relates to a kind of enamelled wire that is used for transmission signals, belongs to the enamelled wire field.
Background technology
Existing enamelled wire, its core adopts copper product to process on the one hand, and promptly the core of existing enamelled wire has only the copper of individual layer.At present, because the price of copper is higher than the price of aluminium, make the cost cost of enamelled wire than higher, still, if adopt the core of aluminium as enamelled wire, the electric conductivity of thread core of aluminum is poor, can not satisfy the conduction requirement of electric elements.On the other hand, the prior art enamelled wire comprises the conductor of some tape insulation layers, outer rubber and plastic cover; Its shortcoming is that some metallic conductors are not consolidated; Outer rubber and plastic cover does not have to bond together with the insulating barrier of metallic conductor, during winding, causes some metallic conductors separately easily.
Summary of the invention
The utility model purpose provides a kind of enamelled wire that is used for transmission signals; This enamelled wire is consolidated into one through pure dissolubility self-adhesive layer; So the one performance is good, can transmit multiple signal, is convenient to distinguish the number of phases; And guaranteed not have lamination between copper layer and aluminium core, thereby the flexibility, ductility, the pull resistance that have guaranteed product all are in preferable shape.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of enamelled wire that is used for transmission signals; Comprise at least two parallel placed metal cores; This metal core outer surface separately all is coated with insulating barrier, and said metal core is made up of thread core of aluminum and the copper layer that coats this thread core of aluminum outer surface, and a pure dissolubility self-adhesive layer is coated on said at least two wires core outer surfaces.
Further improved technical scheme is following in the technique scheme:
As preferably, has an aluminum-copper alloy layer between said thread core of aluminum and the copper layer.
As preferably, said insulating barrier is made up of polyester layer and the layer of polyurethane that is coated on this polyester layer outer surface.
As preferably, said metal core number is three or four, and it is arranged in parallel separately.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
The utility model is used for the enamelled wire of transmission signals, and it has the metal core that has two tape insulation paint films that are parallel to each other at least, and is convenient to distinguish the number of phases; The metal core is consolidated into one through pure dissolubility self-adhesive layer; So the one performance is good, can transmit multiple signal, is convenient to distinguish the number of phases; Secondly; Through can more scientifically control the thickness of copper-clad aluminum bronze layer to copper layer thickness and thread core of aluminum; Make volume ratio suitable and guaranteed not have lamination between copper layer and aluminium core, thereby the flexibility, ductility, the pull resistance that have guaranteed product all are in preferable states.
Description of drawings
Accompanying drawing 1 is used for the enamelled wire structural representation of transmission signals for the utility model.
In the above accompanying drawing: 1, metal core; 2, insulating barrier; 3, thread core of aluminum; 4, copper layer; 5, pure dissolubility self-adhesive layer; 6, aluminum-copper alloy layer; 7, polyester layer; 8, layer of polyurethane.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of enamelled wire that is used for transmission signals; Comprise at least two parallel placed metal cores 1; This metal core 1 outer surface separately all is coated with insulating barrier 2; Said metal core 1 is made up of thread core of aluminum 3 and the copper layer 4 that coats these thread core of aluminum 3 outer surfaces, and a pure dissolubility self-adhesive layer 5 is coated on said at least two wires cores 1 outer surface.
Has an aluminum-copper alloy layer 6 between above-mentioned thread core of aluminum 3 and the copper layer 4.
Above-mentioned insulating barrier 2 is made up of polyester layer 7 and the layer of polyurethane 8 that is coated on these polyester layer 7 outer surfaces.
Above-mentioned metal core 1 number is three or four, and it is arranged in parallel separately.
When adopting the above-mentioned enamelled wire that is used for transmission signals, it has the metal core that has two tape insulation paint films that are parallel to each other at least, and is convenient to distinguish the number of phases; The metal core is consolidated into one through pure dissolubility self-adhesive layer; So the one performance is good, can transmit multiple signal, is convenient to distinguish the number of phases; Secondly, through can more scientifically control the thickness of copper-clad aluminum bronze layer to copper layer thickness and thread core of aluminum, making between volume ratio suitable and assurance copper layer and aluminium core does not have lamination, thereby the flexibility, ductility, the pull resistance that have guaranteed product all are in preferable states.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.
