Abstract
The invention relates to a conductive terminal, with composite layers, wherein said conductive terminal comprises steel layer and copper layer at the outer surface of steel layer. Compared with present terminal, since its inner layer is steel, it has better mechanical property, and the steel layer has copper layer outside, to confirm better conductivity and reduce the material cost.
Description
[technical field]
The present invention relates to a kind of conducting terminal.
[background technology]
Having conducting terminal now, as be used in the PIN pin class conducting terminal in the electric connector, generally all is by copper material or each Albatra metal-punch forming.But mechanical performance and electric conductivity be copper alloy such as beryllium copper preferably all, cost an arm and a leg, and low slightly phosphor-copper or the special copper of price, the relative beryllium copper of its conductance is lower, but its price is also in continuous rise, make production cost improve constantly, if use the lower material punch forming conducting terminal of some prices, it generally reaches requirement than difficulty simultaneously because of mechanical performance and electric conductivity, if mechanical performance does not reach requirement, terminal is easy to generate kneels the pin phenomenon, also can influence the transmission of normal signal if electric conductivity is relatively poor.
Therefore, be necessary to design a kind of novel conducting terminal, to overcome above-mentioned defective.
[summary of the invention]
The object of the present invention is to provide all better and lower-cost conducting terminal of a kind of mechanical performance and electric conductivity.
In order to reach above-mentioned creation purpose, technical scheme of the present invention is to realize like this, a kind of conducting terminal, this terminal is a lamination layer structure, described conducting terminal comprises the steel layer and is arranged on the copper layer of steel layer outer surface, described conducting terminal is cut open, and the ratio that described copper layer accounts for total cross-sectional area is 9%～28%.
Compared with prior art, conducting terminal of the present invention, its internal layer are steel so have mechanical performance preferably, are provided with the copper layer simultaneously outside the steel layer and can guarantee that conducting terminal has the favorable conductive rate, and can effectively reduce material cost.
[description of drawings]
The stereogram that Fig. 1 is a conducting end of the present invention;
Fig. 2 is the zoomed-in view of analysing and observe of conducting terminal shown in Figure 1;
Fig. 3 is the constitutional diagram of conducting terminal shown in Figure 1 and insulating body.
[embodiment]
Below in conjunction with the drawings and specific embodiments conducting terminal of the present invention is described further.
See also Fig. 1 to shown in Figure 3, conducting terminal 1 is a lamination layer structure, this conducting terminal 1 comprises the steel layer 2 that is arranged on internal layer and is arranged on the copper layer 3 of steel layer 2 outer surface, and the internal layer of steel layer 2 is the base material of conducting terminal, and steel layer 2 is combined closely with described copper layer 3 and be an overall structure.Conducting terminal 1 is cut open, the ratio that described copper layer 3 accounts for total cross-sectional area is 9%～28% (these data draw through repeatedly experiment for the inventor), conducting terminal not only has conductivity preferably under this ratio, also has mechanical performance preferably simultaneously, and described steel layer 2 is a steel alloy, and each constituent content of this steel layer 2 is: carbon (C)≤0.08%, silicon (Si)≤0.10%, manganese (Mn)≤0.60%, phosphorus (P)≤0.03%, sulphur (S)≤0.035%, iron (Fe) 〉=99.155%; The content of each element is in the described copper: copper (Cu) 〉=99.90%, silver (Ag)≤25.00PPM, bismuth (Bi)≤1.00PPM, arsenic (As)≤5.00PPM, iron (Fe)≤10.00PPM, nickel (Ni)≤10.00PPM, sulphur (S)≤15.00PPM, strontium (Se)≤25.00PPM, oxygen (O)≤50.00PPM.Be coated with protection metal level 5 outside described copper layer 3, this protection metal level 5 is a nickel, is coated with one deck gold 6 at the nickel outer surface, can effectively reduce the impedance of conducting terminal.Certainly, also can be beneficial to welding, and another part be gold-plated in the outer surface part zinc-plated (not shown) of protection metal level nickel.
This conducting terminal 1 cooperates with insulating body 4 to form electric connector 5 (as shown in Figure 3), this electric connector 5 uses conducting terminal 1 of the present invention, this conducting terminal 1 internal layer is a steel so have mechanical performance preferably, simultaneously outside the steel layer, be provided with the copper layer and can guarantee that conducting terminal has the favorable conductive rate, because of the cost of conducting terminal is low than copper alloy, so can effectively reduce the production cost of electric connector.
