Description
Technical field
The utility model is related to a kind of automobile connector, and in particular to a kind of automobile connector laser welding terminal.
Background technology
Automobile connector is used for realizing electrical connection or signal transmission that its operation principle is by socket jacket（Material is modeling
Material）And female terminal（Material is metal）Combination and plug boot（Material is plastics）And plug terminal（Material is metal）'s
Combined inserting realizes the connection of circuit together.The critical piece for realizing circuit connection is plug terminal and female terminal, and is inserted
Seat sheath and plug boot are that the part of fixed and protective effect is played to female terminal and plug terminal.Actually make on current automobile
Terminal material is generally copper alloy, and its electric conductivity and mechanical performance can substantially meet the demand of automobile connector.
Terminal positive force refers to generation in the plug terminal and female terminal contact surface of connector and perpendicular to the contact
The power on surface.From for the angle of the conduction property of terminal, the positive force of terminal is bigger, and contact resistance is smaller, and conduction property is got over
It is good, therefore, designer wishes larger positive force.From for the angle of the assembly performance of terminal, the positive force of terminal is bigger,
Contact engaging and separating force is bigger, and assembly performance is poorer, therefore, designer wishes less positive force.Comprehensive two aspect factors, designer
Can neither be excessive and can not be too small during design terminal positive force, greatly limit the scope of design of positive force.Connector is in reality
When using, due to high temperature and the collective effect of timeliness, the Cu alloy material that terminal is used occurs Stress Release phenomenon, so that
Reduce the positive force of terminal, when Stress Release reaches to a certain degree, the positive force of terminal can be reduced to and can not meet grafting
The conduction property requirement of device, makes connector fail.
A kind of Chinese utility model patent " automobile connector female terminal with the positive force holding structure " applying date
On April 24th, 2014, application number ZL201420203015.3, grant date September in 2014 discloses terminal on the 10th using double-deck material
The scheme of material, solution is Stress Release problem under the Cu alloy material high temperature that terminal is used.By using high temperature resistant material
Expect the Stress Release that the secondary clamp system of generation is solved the problems, such as under Cu alloy material high temperature, but because secondary clamp system bag exists
Main body outer layer, punching press resilience problem cannot be solved, so, the secondary clamping effect of the product is unable to reach design requirement.
Terminal and sheath need the positioning after being installed and installed by elastic construction when coordinating.The bullet used on terminal
Property structure refer to by terminal and sheath assembling required for elastic construction design on terminal, in terminal and sheath assembling process
In, by designing the elastic construction stress deformation on terminal, realize the assembling of terminal and sheath.It is assembled in terminal and sheath
Behind position, the elastic construction designed on terminal reverts to reset condition because stress is released.The elastic construction and design are in shield
The cooperation of the hanging platform structure for putting, it is ensured that effective positioning of the sheath to terminal.Elastic construction can only meet reluctantly in the prior art
Design requirement, but when actually used, especially the elastic construction often occurs the situation of failure under high temperature action.
July 21 2014 " automobile connector of tine resiliency structural strengthening " applying date of Chinese invention patent, application number
ZL2014103447515, grant date August in 2016 discloses scheme of the terminal using double layer material on the 24th, and solution is terminal
When coordinating with sheath, when elastic construction design is on terminal, the problem of elastic construction reseting performance difference.
When actually used, double layer material structure can substantially solve positive force reduction and the tine resiliency that Stress Release is caused
The problem of structure reseting performance difference, but double layer material has been used, difficulty is brought to Sheet Metal Forming Technology, due to the stainless steel for newly increasing
Resilience problem occurs in punching press for material, and cannot be solved by the compensation of size, so, the precision of product it is difficult to ensure that.
