Why do connector assembly factors have metal plating?

The final stage of electronic connector production is the finished product assembly, will be plated pins and injection molding box seat insertion method has two kinds: alone or combination of pairs of insertion, alone or combination of pairs of insertion refers to the insertion of a pin each time, the combination of pairs of insertion of a number of pins together with the box seat insertion, regardless of which method of insertion, the producer is required to test all the pins in the assembly stage whether there is a lack of correct positioning, and the other class of Routine inspection mission is to cooperate with the connector on the surface of the pitch measurement off.

And stamping stage, the connector assembly also put forward to the automatic inspection system in the detection of speed challenges, although most assembly line beat for one to two pieces per second, but on each through the camera connector, the visual system usually need to complete a number of different detection projects, so the detection of speed has again become an important automotive connector system performance indicators. After the assembly is completed, the connector shape scale in the order of magnitude greater than the individual pins promised to the scale of the public service, this point also brings another problem to the visual inspection system, for example: some connector box seat scale beyond one foot and has hundreds of pins, each pin position detection accuracy must be in the thousands of inches within the scale, obviously, in an image can not be completed on a foot-long connector detection, the visual inspection system can only be completed in a foot-long connector detection, the visual inspection system can only be completed in a foot-long connectors. Connector detection, visual inspection system can only detect a limited number of pins each time in a small field of view quality, in order to complete the detection of the entire connector there are two ways: the use of multiple cameras (so that the system consumption increases), or when the connector in front of a lens through the period of successive triggering camera, the visual system will be successive ingested a single Zhen image " Stitching " up to the automotive connectors, in order to identify the quality of the entire connector is qualified, the latter one. The whole connector quality is qualified, the latter method is PPT visual inspection system in the connector assembly is completed after the usual selection of detection methods. Electronic connectors are very important parts in the electronic components industry, and engaged in electronic engineering and technical personnel can be found: most connectors will be plated with a very special layer of plating, then the connector plating in the end what is the special meaning of the connector plating, the reason why the connector to have contact with the plating, this is because the plating can not only maintain the connector to reduce the environment to reduce the corrosion of the intrusion, increase the connector's Durability and wear resistance, it can also assist in the establishment and maintenance of stable connector impedance from the electrical function, specific performance such as. First, the connector plating helps to improve the mechanical function. New energy vehicle connectors and mechanical function related parameters that is the first is to affect the durability of the plating or wear and fit elements, if you want to think about these elements, then in the same fundamental role there will be two different points of view, that is, the multi-point contact interface in the process of relative movement of the sharing of cold welding, the most important mechanical function contains hardness, ductility and coefficient of friction of the plating materials, and these Characteristics need to rely on the connotative properties of the plating material and its use in the work process, therefore, the connector plating is very important. Second, the connector plating corrosion resistance. Connector is the first thing to think about that is corrosion maintenance, most of our electrical connectors contact shrapnel are made of copper alloy, and copper alloy in the typical electrical connector operating environment that is the most simple to be corroded, such as oxidation and vulcanization.
