Rectangular Industrial Plug Structure Introduction

Connector Insert is an electrical accessory operated by hand, so there are several requirements: first, the size must meet national standards and be safe and reliable; second, installation and wiring should be convenient; third, the handle is suitable for holding and easy to use; fourth, it has beautiful appearance and reasonable structure. Introduction to the structure of industrial plugs. Shell: The function of the shell is to load and protect the internal parts of the plug, and its appearance is suitable for hand operation; the handle surface design of the shell is very particular, usually designed with multiple stripes or multiple round diamonds to increase friction, so that the hand is easy to hold and plug and pull. Pin: The pin is the conductive part of the plug, also known as the contact. Plugs with a rated voltage greater than 50V should have a ground pole pin, which is thicker and longer in diameter and can withstand the rated working current. The diameter and length of the phase pole and neutral pole pins are shorter than the ground pole. In this way, the ground pole is connected first when plugging in, and the ground pole is left last when unplugging, ensuring safe grounding.
