Description
Technical Field
The invention relates to the technical field of connectors, in particular to a method and a device for testing a connector.
Background
Present electric automobile's high-voltage wire harness all can have some requirements of bending when whole car is arranged, but be subject to whole car arrangement space, many pencil can't realize arranging according to the bend radius that requires, especially to the terminal position of being qualified for the next round of competitions of high-voltage connector plug, because bend radius appears in the pencil is little, can lead to arranging the exogenic action that brings to receiving for a long time to the inside waterproof rubber ring of high-voltage connector and inside metal contact, some vibrations of whole car in addition, if the operating mode is severe, present sealed inefficacy or the condition that contact resistance increases after a period, cause the vehicle short circuit or the return circuit heating aggravation, can lead to the vehicle to catch fire seriously.
In the prior art, a measure of increasing a fixed point within a specified distance of a wire outlet at the tail end of a plug of the high-voltage connector is adopted, but due to the fact that most of the fixed points are fixed through a ribbon or a buckle, certain deviation exists, and the stress of a waterproof rubber ring inside the connector and a metal contact pair inside the connector cannot be fundamentally solved. Moreover, after the tail end of the connector of some assemblies with movement (with relative movement with the vehicle body) is led out, the first fixed point cannot be ensured to be also on the movement assemblies, and the tail end of the connector can be randomly bent. And the application of the ultrasonic welding process in the industry is mature day by day, and the stress requirement of the ultrasonic welding wire harness on the welding position is severer.
The high-voltage connector schemes of the electric automobile are all to ensure that the size and the weight of the connector are as small as possible, corresponding wire harness fixing is not considered to be added at the rear end of the connector, only fixing points need to be added within a certain distance after the tail end of the connector is led out for a vehicle, and the stress borne by the connector terminal pair is ensured to be within a controllable range. There are also some connectors on the market already provided with a temperature sensor for detecting the temperature of the assembly. At present, most of connectors in the market are matched with copper cables, and only a crimping mode is adopted. However, with the improvement of competitive power of electric vehicles due to cost reduction, the application of aluminum cables is gradually increased year by year, the production of aluminum wire harness assemblies is more mature, and a welding process is required to be adopted to ensure that the connection resistance of the aluminum cables and connectors after matching meets the requirements. Firstly, the conductivity and flexibility of an aluminum material are poorer than those of a copper material, the aluminum wire harness conducting the same current needs to be thicker than the copper wire harness, the bending requirement is severer, and the stress born by the matched position of a terminal and a cable is larger; and secondly, the aluminum material and the terminal are welded, and the wire breakage is easy to occur after the welding position bears stress, so that the conductivity is directly influenced, the temperature of the connector assembly is increased, the system misjudgment is caused, the corresponding function of the connector is stopped, and safety accidents are caused. Therefore, after the aluminum cable is matched with the connector, stress and temperature detection, control and system control strategies of the welding position of the connector terminal and the cable become key problems to be solved urgently at present.
In view of the above problems, no effective solution has been proposed.
