Description
Technical field
The present invention relates to the interconnection technique field of cable and terminal, in particular to a kind of aluminium alloy automobile cable and copper tip
Between connection method and connection structure.
Background technique
With the continuous improvement that people require vehicle economy, and the electronics categories on automobile are also constantly increasing
Add, automotive wire bundle is more and more, becomes increasingly complex, and the increase of the type and quantity of harness causes the weight of automobile also increasingly
Height, for new-energy automobile, light-weight design is the means that must assure that vehicle economy.
The light-weight design taken on automotive wire bundle at present mainly uses aluminum metal conductor to substitute copper conductor, due to different
Kind metal connection is easy to produce electrochemical corrosion, and the solution mainly used at present is connected using copper-aluminum transition terminal
It connects.Copper-aluminum transition terminal is to be connected the part interatomic combination of progress with aluminium in copper to reach anti-corrosion purpose, such terminal
Processing cost is relatively high.It cannot minimize, be unable to broad aspect use.
Automobile electric wire terminal dissimilar metal junction corrosion principle: different metal contact, the potential difference due between, in air
In, metal surface will form a kind of micro cell, also referred to as corrosion cell, and oxidation reaction occurs on anode, dissolves anode, yin
Extremely upper that reduction reaction occurs, general is play a part of to transmit electronics.The Crack cause of corrosion cell is mainly due to metal surface
The moisture in air has been adsorbed, water membrane is formed, thus has made CO in air2, SO2, NO2Etc. being dissolved in this layer of moisture film, formed
Electrolyte solution.Especially it can accelerate this reaction in the high temperature that cable generates under conditions of transmitting electric energy.
Summary of the invention
It is an object of the present invention to be directed to connect existing appearance between existing aluminium alloy automobile cable and copper tip
Perishable problem and a kind of connection method that do not allow between perishable aluminium alloy automobile cable and copper tip is provided.
The second object of the present invention is to provide the connection structure between a kind of aluminium alloy automobile cable and copper tip.
As the connection method between a kind of aluminium alloy automobile cable and copper tip of first aspect present invention, including it is as follows
Step:
(1) aluminium alloy conductor in aluminium alloy automobile cable is separated, aluminium alloy conductor is then used into ultrasonic bonding
Method is welded on copper tip；
(2) sealant layer of one layer of corrosion-and high-temp-resistant is coated on the surface of the aluminium alloy conductor of welding position and is consolidated
Change；
(3) it is protected outside the sealant layer, aluminium alloy conductor and the copper tip of welding position and aluminium alloy automobile cable
It puts on pyrocondensation and coats one layer of thermoplastic casing.
It is closed as the connection structure between a kind of aluminium alloy automobile cable and copper tip of second aspect of the present invention, including aluminium
Golden automobile cable and copper tip, the aluminium alloy automobile cable are stripped out one section of aluminium alloy conductor, and the aluminium alloy conductor is super
Sound wave is welded on a part of copper tip, and one layer of corrosion-and high-temp-resistant is coated on the surface of the aluminium alloy conductor of welding position
Sealant layer, protected outside the sealant layer, aluminium alloy conductor and the copper tip of welding position and aluminium alloy automobile cable
It puts on pyrocondensation and coats one layer of thermoplastic casing.
Due to using technical solution as above, compared with the prior art, the invention has the following advantages:
(1) using ultrasonic wave connection technology connection aluminium alloy conductor and terminal, guarantee its good contact.Company compact simultaneously
Binding structure is that contact portion is very close to each other, will not trapped air；
(2) sealant of fire resistant anticorrosive is added in coupling part, the metal of completely isolated air and junction portion connects
Touching, prevents metal surface from adsorbing the moisture in air, cannot form the redox reaction of corrosion；
(3) thermoplastic casing protection is carried out on the sealant that the sealant of fire resistant anticorrosive is formed, first is that protection sealing
Glue-line is not mechanically damaged, second is that secondary seal can be formed.
Detailed description of the invention
Attachment structure schematic diagram of the Fig. 1 between aluminium alloy automobile cable and copper tip of the invention.
Specific embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is participated in, the connection structure in figure between the aluminium alloy automobile cable provided and copper tip, including aluminium alloy automobile
Cable 10 and copper tip 20, aluminium alloy automobile cable 10 are stripped out one section of aluminium alloy conductor 11,11 ultrasonic wave of aluminium alloy conductor
It is welded on a part of copper tip 21, guarantees that aluminium alloy conductor 11 is well contacted with a part of copper tip 21, while compact company
Binding structure is that contact portion is very close to each other, will not trapped air.
The sealant layer of one layer of corrosion-and high-temp-resistant is coated on the surface of the aluminium alloy conductor 11a of welding position 50
30, completely isolated air is contacted with the metal of junction portion, prevents metal surface from adsorbing the moisture in air, cannot form corruption
The redox reaction of erosion.
In the copper tip 21 and aluminium alloy automobile cable 10d of sealant layer 30, aluminium alloy conductor 11 and welding position 50
Oversheath 12 on pyrocondensation coat one layer of thermoplastic casing 40, first is that protecting sealant layer not mechanically damaged, second is that can be with shape
At secondary seal.
