2 pin 4540310 Automotive Electrical Car Wire Harness Connector Plug Socket

With the rapid development of the automotive industry and electronic technology industry, the use of electronic technology in automobiles has become more and more common, and users' requirements for all aspects of automobiles have continued to improve. In addition to its own functionality, many entertainment and security measures have been added. However, the body space of the car is limited. Therefore, the design of the car line beam is very important. The improvement of the reliability of the car beam design is a tedious industrial trial process, and it must have a comprehensive control of all aspects of the car beam system design. This article analyzes and summarizes the designs, assembly, and wire beam tests that may occur, etc., and put forward strict control of reliability in various links. The wiring design of the car not only has important significance for the safety of the car itself, but also has a vital role in people who trust this product and the safety of people in driving.

In plastic parts, many industrial products have the design of internal and external thread structures. The threading mechanism is complex, the mechanism of the mechanism is low, it is easy to wear and often occur. Solving plastic decks has always been a problem. Generally speaking, the threads on the plastic parts are divided into two types: extraction thread and internal thread. The outer thread is relatively easy to form. It is usually formed by slider. After forming, open the slider to remove the plastic parts. You can also use the active ring to form the outer thread. After the forming, the plastic parts are taken out of the mold with the activity ring, and then the active ring is removed from the outer rotation to obtain the plastic part with the external thread. When the internal threads on the plastic part are formed, they are limited by mold space. Therefore, its modeling method is relatively complicated. Common forms include active core mold extraction, forced threading, inner pumping threads, and internal rotation threads. The production efficiency of activity core mold extraction threads is low, but the mold structure is simple, and it adapts to small batch production; the automatic thread is high efficiency, the quality is stable, and the mass production is adapted to large quantities. In the automatic rotation of the threading mold structure, problems such as reliability, stability and practicality of structural design must be solved.

-, plastic parts analysis

The author is locked outside the school, as shown in Figure 1. The raw material of the product is ABS engineering plastics. ABS resin is one of the five synthetic resins. Its impact resistance, heat resistance, low temperature resistance, excellent chemical resistance and electrical properties, it also has the characteristics of easy processing, stable product size, good surface gloss, etc. Good molding craftsmanship, the contraction rate of materials is 0.5. There are no special requirements for this product, and there must be defects such as shrinkage, bubbles, flow marks and strains on the surface. According to the analysis of plastic parts and the requirements of user output, the mold structure adopts a two -cavity design.
