Introduction To Car Connector Production Steps

Everyone buys and sells materials all day long and knows hundreds of car connector models. They hold it in their hands every day and hand it out on the road, but do you know how this tiny car connector was made? As we all know, connectors are made up of molded housing and terminals. What manufacturing processes do you need to go through to make molded housing and terminals and then assemble them into connectors? This article describes the manufacturing process of the following connectors.

1. Stamping.

The manufacturing process of automotive connectors generally starts with stamping the pins. Electronic connectors (pins) are stamped from thin metal strips using large high-speed presses. One end of the large metal belt is sent to the front end of the punch, and the other end is wound to the winding wheel through the hydraulic table of the punch.

2. Electroplating.

Automotive connector pins should be sent to the plating section after stamping. At this stage, the electrical contact surface of the connector is plated with various metal coatings. Problems similar to the stamping phase occur when stamping pins are fed into plating equipment, such as twisted, notched, or deformed pins. With the techniques described in this paper, such quality defects can be easily detected.

However, for most machine vision system suppliers, many quality defects in the electroplating process are still "off-limits" for inspection systems. Manufacturers of electronic connectors want inspection systems that can detect a variety of inconsistent defects, such as tiny scratches and pinholes on the plated surface of connector pins. Although these defects are easily recognized for other products such as the bottom of an aluminum can or other relatively flat surface. But because of the irregular and angled surface design of most electronic connectors, it is difficult for visual inspection systems to obtain the images needed to identify these subtle defects.

As some types of needles have multiple layers of metal coatings, manufacturers also want inspection systems that can distinguish between various metal coatings to verify their presence and proportions. This is a very difficult task for vision systems using monochrome cameras, since the gray scale of the image is almost the same for different metal coatings. Although the cameras of the color vision system were able to successfully distinguish these different metal coatings, there was still the problem of difficult illumination due to the irregular angles and reflection effects of the coated surfaces.
