Description
Technical field
It the utility model is related to automotive connector field, and in particular to a kind of electric car high-tension connector porous wear-resistant elasticity
Interior contact ring.
Background technology
Electric automobile has more than 600V high pressures and more than 300A high current systems, traditional automotive connector contact structures
Standard requirement, the electric car high-tension connector contact structures used at present can not all be met in electrical property safety and contact resistance
Although middle petal design processing is simple but contact point is few, contact resistance is larger；Although double helix and coil spring structure contact point are more
But processed complex, cause the market price higher.Meanwhile contact body structure surface is silver-plated or golden in high-tension connector, to reduce contact
Resistance, because silver-colored and golden hardness is low, rub resistance is poor, plug number is low.
Utility model content
The technical problems to be solved in the utility model is that traditional automotive connector contact structures contact resistance is larger, processed
It is complicated, rub resistance is poor, plug number is low, there is provided a kind of cost for reducing electric car high-tension connector, raising coating hardness and resistance to
Contact ring in the electric car high-tension connector of the porous wear-resistant elasticity of frictional property.
In order to solve the above technical problems, the utility model uses following technical proposals：In a kind of electric car high-tension connector
Ring is contacted, including interior contact ring body and plating are located at the overlay coating of interior contact ring body outer surface, described interior contact ring sheet
Body is the body of both ends open；The tube wall of the body is the arcwall face being recessed to tubular body, and described tube wall is provided with and opened
Hole, described tube wall are further opened with linear slit along body axis direction.
Described linear slit width is less than 0.5mm, a diameter of 1.4-1.6mm of described perforate.
Described interior contact ring body is corson alloy open tube.
Described perforate is staggeredly uniformly distributed on tube wall.
Described overlay coating is AgCu alloy layers, AgSb alloy layers, AgPd alloy layers or AuAg alloy layers
One kind.
The thickness of described overlay coating is 0.5-2.0 microns.
The utility model can improve the hardness and rub resistance of coating in the case of ensureing that contact resistance is standard compliant；
Improve the safe and stable property of application and the life-span of high-tension connector.
This patent also has beneficial effect：1st, this patent is simple in construction, dependable performance, has wide range of applications, can
Effectively promote the application of high-tension connector；2nd, the utility model realizes the netted linear contact with plug, and contact resistance is low,
Reach the contact resistance requirement of LV215 high-tension connectors；3rd, AgCu alloy layers, AgSb alloy layers, the AgPd alloys used
Coating, AuAg alloy layers replace the pure Ag or pure Au coating of interior contact ring to improve the wearability of interior contact structures.AgCu is closed
When Cu content is 1-2% in gold plate, wearability improves 3 ~ 5 times than silver；Sb content is 1.5-2.5% in AgSb alloy layers
When, wearability is higher 10 ~ 12 times than silver；When Pd content is 8-10% in AgPd alloy layers, wearability improves 5 ~ 10 than fine silver
Times；When Ag content is 30-40% in AuAg alloy layers, wearability improves 8 ~ 10 times than proof gold.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1：The utility model includes interior contact ring body 1 and plating is located at the table of interior contact ring body 1 outer surface
Face coating, described interior contact ring body 1 are the body of both ends open；The tube wall of the body is the arc being recessed to tubular body
Shape face, described tube wall are provided with perforate 3, and described tube wall is further opened with linear slit 4 along body axis direction.The setting of linear slit 4
It is easy to processing of the present utility model.
The described width of linear slit 4 is less than 0.5mm, a diameter of 1.4-1.6mm of described perforate 3.The utility model perforate 3
A diameter of 1.5mm, it is described it is interior contact ring body 1 wall thickness be 0.5 mm, the internal diameter at both ends open be 8 mm, a length of 19
Mm, tube wall to the internal diameter of tubular body recess be 5mm.
Described interior contact ring body 1 is corson alloy open tube.Corson alloy open tube has high resiliency.
Described perforate 3 is staggeredly uniformly distributed on tube wall.
Described overlay coating is AgCu alloy layers, AgSb alloy layers, AgPd alloy layers or AuAg alloy layers
One kind.
The thickness of described overlay coating is 0.5-2.0 microns.
Cu content is 1-2% in AgCu alloy layers；Sb content is 1.5-2.5% in AgSb alloy layers；AgPd is closed
Pd content is 8-10% in gold plate；Ag content is 30-40% in AuAg alloy layers.Alloy layer can pass through plating or magnetic
Sputtering method is controlled to obtain.It is using corresponding alloy as target that magnetron sputtering method, which prepares alloy layer, is 10-3 ~ 10-4 in Vacuum Deposition
Pa, lead to the vacuum to 0.1 ~ 1 Pa such as inert gas argon gas, then apply up to 5 kV high voltage in negative and positive interpolar, make
Inert gas produces glow discharge and ionized, under the attraction of negative electrode negative high voltage, the accelerated simultaneously bombarding cathode of inert gas ion
Target, make some atoms of target be sputtered out, coating is formed with high speed deposition to anode surface, increases by one in sputtering equipment
The individual magnetic field parallel with target material surface, makes electronics deflect, and does not go bombardment plating piece to prevent plating piece temperature from raising.
