The difference of header/wafer/housing

The connector is the core part of the connector to complete the electrical connection function. Generally, the contact pair consists of positive contact parts and negative contact parts, and the electrical connection is completed through the insertion of Yin and Yang contact parts.

The purpose of the wafer (insulator) is to arrange the contacts in the desired position and spacing and to ensure insulation between the contacts and between the contacts and the housing. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials to be processed into insulators.

The housing is the outer cover of the connector, which provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment of the plug and socket to secure the connector to the device.

The connector used in electronic products is board to board connector, board to board connector is used to connector two PCB, so as to achieve mechanical and electrical connection, its characteristics are male and female connector pair use. In the test of board-to-board connector, it can be connected by shrapnel microneedle module to realize current transmission and signal conduction. The maximum constant current test can withstand 50A, when the board to board connector test current concentrated in the same material conduction, constant resistance, electrical stability, almost no current attenuation.
