Description

Technical Field

[0001] The invention relates to the technical field of terminals, and in particular to an insulating and waterproof sealed terminal. Background Art

[0002] With the rapid development of the national economy, automation equipment is increasingly used in the manufacturing industry, and automobiles are becoming more and more popular. Currently, the commonly used automation equipment and automobiles in China mainly use terminal blocks as wiring tools, among which intermediate crimping terminals account for a large proportion.

[0003] At present, the main material of this type of terminal is polyvinyl chloride (PVC), and some of them use heat shrink middle crimp terminals. The PVC terminal itself has low material strength, no shrinkage, cannot be sealed and waterproof, and has poor aging resistance, which makes the terminal product have a short service life and poor safety. Heat shrink middle crimp terminals have certain limitations when used in areas that cannot be heated, such as high altitude and underwater, because they need to be heated. In addition, in areas such as locomotives and outdoor advertising that require outdoor wiring, due to weather reasons, the product's wiring terminals need to have high chemical resistance and stability, but PVC materials have poor corrosion resistance and cannot be used in this field. Moreover, after the joint is completed, the wiring harness near the joint will shake with different conditions, which may cause the sealant to fall off or the joint to loosen in the long run. For this reason, we have proposed an insulated waterproof sealed terminal. Summary of the invention
