Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 for the utility model provide for improve circuit connect electric installation in plasticity conducting strip front elevation; Fig. 3 for the utility model provide for improving two busbars in electric installation that circuit connects and the explosive view of plasticity conducting strip; As shown in figures 1 and 3, the electric installation for improving circuit connection that the present embodiment provides, comprises plasticity conducting strip 101; Plasticity conducting strip 101 is in tabular, and for being arranged between two busbars 104, under the clamping force effect of two busbars 104, plasticity conducting strip 101 can plastic deformation the gap of filling between two busbar 104 contact-making surfaces.Wherein the shape of the structure of plasticity conducting strip 101 has multiple, and can be circle, rectangle, square etc., user can make plasticity conducting strip 101 according to the shape of busbar 104.In addition, the material of plasticity conducting strip 101 also can be multiple, such as: can be one or more of the conductive metal material such as aluminium, nickel, tin, copper, silver, also can be the non-metallic conducting material such as graphite, conducting polymer composite.
The electric installation for improving circuit connection that the present embodiment provides, it is provided with plasticity conducting strip 101 between two busbars 104.When two busbars 104 overlap by needs, first plasticity conducting strip 101 is placed between two busbars 104, then two busbars 104 are overlapped, plasticity conducting strip 101 is extruded simultaneously, thus make plasticity conducting strip 101 that deformation occur, plasticity conducting strip can plastic deformation the gap of filling between two busbar contact-making surfaces, and then the contact area of plasticity conducting strip 101 and two busbars 104 is increased, and then avoids between two busbars 104 and produce contraction protein.So increase busbar 104 electric conductivity of two overlap joints, reduce use cost.
In addition, because plasticity conducting strip can plastic deformation the gap of filling between two busbar contact-making surfaces, thus make the contact decreasing two busbars and air, so the electric installation for improving circuit connection in the present embodiment, namely increase the busbar electric conductivity of two overlap joints, reduce contact resistance, also just reduce energy consumption cost; Significantly reduce again the corrosion on electrical contact surface, decrease the maintaining cost of circuit.
Fig. 4 for the utility model provide for improving two busbars in electric installation that circuit connects and the use shape body schematic diagram of plasticity conducting strip; As shown in Figure 1 and Figure 4, on the basis of above-described embodiment, further, plasticity conducting strip 101 is provided with installing hole 102; Plasticity conducting strip 101, for wearing bolt 105, is fixed between two busbars 104 by bolt by installing hole 102.Wherein installing hole 102 can be one, and also can be multiple, the installing hole 102 of plasticity conducting strip 101 be corresponding with the installing port on busbar 104, thus is convenient to the installation of plasticity conducting strip 101 and fixes.
Fig. 2 for the utility model provide for improve circuit connect electric installation in plasticity conducting strip cutaway view; As depicted in figs. 1 and 2, on the basis of above-described embodiment, further, plasticity conducting strip 101 is metal foam sheet, and metal foam sheet is alveolate texture; The outer surface of metal foam sheet is provided with multiple conduction and gets an electric shock, and multiple conductive contact abuts with busbar.Wherein, because plasticity conducting strip 101 is in cellular, the outer surface of metal foam sheet is provided with multiple conductive contact 103, because conductive contact 103 can pierce through the oxide-film on busbar 104 surface, thus the resistance reduced between two busbars 104, increase the electric conductivity between two busbars 104.
In the related, when two busbars 104 mechanically overlap, due to the rough surface of two busbars 104, make only there is several contact point between two busbars 104, so when electric current is transitioned into the very little several contact point in cross section from the conductor larger from cross section, current density will change, and current line is sharply shunk, produce extra resistance, become contraction protein (Rs).When the physicochemical property of contact-making surface surrounding medium changes or temperature raises, just make the chemical action of the specified oxidation of contact surface and medium more serious, the oxide-film produced is called film resistance (Rb).Then contact resistance (Rj) with the pass of contraction protein (Rs) and skin covering of the surface resistance (Rb) is:
Rj＝Rs+Rb＝K/(0.102F)n(μΩ)
In formula:
F-contact Contact pressure (N);
N-with on contact form (point, line, surface contact) pressure limit and contact-making surface
The index that contact is counted and distribution situation is relevant;
K-with contact material surface appearance, the index that the way of contact is relevant;
