Description
Technical field
The utility model belongs to electric components technical field, specifically a kind of spray copper aluminium electrode.
Background technology
Electrode is common electric components, and the most commonly used material is copper, the mutual docking of copper material, and electric conductivity is good
Good, the current strength born is big, and security performance is high, but the price of copper is relatively high, and corresponding cost sharply increases.
Achieve the purpose that save copper material to save cost, existing way is usually that the middle part material of electrode is changed to aluminium
Material ensures can comply with standard at docking in one layer of copper powder of outside spraying plating of aluminium, and is only used using existing mode
A thin layer of coating can cause coating to wear due to being used for a long time, and so as to cause that can not meet at docking using standard, use
Safety declines.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of spray copper aluminium electrode, this kind sprays copper aluminium electrode can be effective
The problem of safety declines caused by coating is worn is prevented, it is simple in structure easy to assembly.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of spray copper aluminium electricity
Pole, including aluminum electrode body, sprayed coating, the first tube-like piece made of copper, the second tube-like piece made of copper and conductive joint filling layer；Ontology
Middle part is provided with through-hole both ends and is respectively arranged with annular groove and counterbore；First tube-like piece and second tube-like piece are from two
End penetrates the through-hole and is threadably secured, and annular barb is provided on first tube-like piece, the annular barb is caught in
In the annular groove, flange is provided on second tube-like piece, the flange is matched with the counterbore, is set on the flange
It is equipped with plug hole, the conductive joint filling is provided in first tube-like piece, second tube-like piece and the gap of the ontology
Layer.Using the structure since the first tube-like piece and the second tube-like piece are made of copper, it effectively prevent caused by coating is worn
The problem of safety declines, it is close so that bullet is tightly formed between ontology by the rotatable engagement of the first tube-like piece and the second tube-like piece
The very high gap of envelope property injects conductive joint filling layer and increases electric conductivity so that whole good conductivity can meet in this gap
Use standard.
In above-mentioned technical proposal, it is preferred that the counterbore and the flange are the hexagon being mutually matched.Using the knot
Structure so that limit can be matched between counterbore and flange, facilitates installation.
In above-mentioned technical proposal, it is preferred that one end with annular barb is provided with and screw on first tube-like piece
Knife or the matched rotation slot of spanner.It is more convenient so that the first tube-like piece and the second tube-like piece screw using the structure.
The utility model compared with prior art, has the advantages that：Using the structure due to the first tube-like piece and
Second tube-like piece is made of copper, effectively prevent the problem of safety declines caused by coating is worn, passes through the first tubulose
The rotatable engagement of part and the second tube-like piece makes bullet tightly form the very high gap of leakproofness between ontology, injects in this gap
Conductive joint filling layer increases electric conductivity so that whole good conductivity can meet using standard.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model embodiment.
Fig. 2 is the overlooking structure diagram of the utility model embodiment.
Fig. 3 is the present invention looks up structural representation of the utility model embodiment.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 3,
A kind of spray copper aluminium electrode, including aluminum electrode body 1, sprayed coating 2, the first tube-like piece 3, the second tube-like piece 4 and conductive joint filling layer
5；1 middle part of the ontology is provided with 11 both ends of through-hole and is respectively arranged with annular groove 12 and counterbore 13；First tube-like piece 3 with
Second tube-like piece 4 penetrates the through-hole 11 from both ends and is threadably secured, and annular is provided on first tube-like piece 3
Barb 31, the annular barb 31 are caught in the annular groove 12, and flange 41 is provided on second tube-like piece 4, described
Flange 41 is matched with the counterbore 13, and plug hole 42, first tube-like piece 3, second pipe are provided on the flange 41
The conductive joint filling layer 5 is provided in shape part 4 and the gap of the ontology 1.Using the structure due to the first tube-like piece and second
Tube-like piece is made of copper, effectively prevent the problem of safety declines caused by coating is worn, by the first tube-like piece and
The rotatable engagement of second tube-like piece makes bullet tightly form the very high gap of leakproofness between ontology, and injection is conductive in this gap
Joint filling layer increases electric conductivity so that whole good conductivity can meet using standard.Using the tin note of fusing in the present embodiment
Enter and forms conductive joint filling layer in plug hole.
