What is the difference between metal plate to pogopin connector and plastic plate to pogopin connect

　　1. Mechanical service life

　　The mechanical life of the pogopin connector of the board refers to the life of the number of insertions, and the industry standard generally stipulates 500~1000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the metal shell and the plastic shell should not exceed the value specified in the standard.

　　2. Electrical performance

　　According to the specified standard values, such as voltage, current, contact resistance, insulation resistance, etc., the metal is the same as the plastic case.

　　Three, environmental factors

　　Its environmental parameters include environmental temperature, humidity, temperature sudden change rate, atmospheric pressure and corrosive environment, etc. The steel plate has a significant impact on the performance of the board-plywood during use, storage, and transportation. Therefore, the corresponding metal shell must be selected according to the actual environmental conditions, which is a little better than plastic.

　　Four, wiring method

　　Termination method refers to the connection method of connecting board-to-board male and female contacts and wires and cables with metal contacts. Like plastic shells, metals are divided into welding, crimping, winding, piercing, and screws. Overall analysis, except for the need to connect with a shielding function, the performance of metal and nylon PA66 plastic housings is not much different in all aspects. Plastics are cheaper than metal shells and have a more reasonable structure.
