The basic properties of the connector can be classified into three categories: the mechanical properties, Electric Performance and environmental performance. (1) mechanical properties The connectivity, the power plug is an important mechanical properties. Plug power into insertion and extraction force (also known as separation of forces pull force), the two requirements are different. Another important mechanical properties is the mechanical life of the connector. Mechanical life is actually a durability index, the national standard GB5095 Chinese call it machinery. It is based on an insertion and a pull out for a Cycle To the provisions of the plug connector can cycle normally after the completion of its connectivity (such as contacts Resistance Value) basis as the judge. Plug power connector and mechanical life and the structure of contact (positive pressure on the size), access to parts of the coating quality (sliding friction coefficient) and the dimensional accuracy of contact arrangement (aligned degrees) about. (2) electrical properties Connector electrical performance, including the main contact resistance, insulation resistance...more

The use of hydraulic systems is prevalent in our mechanized world. On a smaller scale, we experience hydraulics on a daily basis: On doors to prevent them from slamming; on exercise equipment to provide resistance; and on brakes to slow or stop motor vehicles. Hydraulics are also found on airplanes, elevators and most amusement park rides.However, industry makes use of hydraulics on a much different level. Construction equipment, robotics, stampers, injection molds and a multitude of other operations within factories and manufacturing plants are dependent upon hydraulics in order to function. A very basic description of how hydraulics work is the application of force from one point to another using a pump or piston with an incompressible fluid in between the two points. An incompressible fluid is a liquid such as oil that is able to "bounce back" or to return to its original density. Keeping Oil CleanIndustrial hydraulic machinery undergoes a great deal of stress due to the constant repetition these systems are tasked with on a daily basis. This is the case with any piece of equipment using oil; especially under demanding conditions where the oil must be filtered and kept clean to...more
