Control terminal assembly of power semiconductor module where terminals are contained in connector housing

摘要

An integrated gate bipolar transistor (IGBT) intelligent power module (1) has a power device, driving circuit and protective circuit for the power device, and a control terminal assembly (3) for control signals connected to the driving circuit and other control circuits in the power module. The control terminal assembly (3) is constructed as a receptacle-type connector with the terminals contained in the connector housing (3b). The openings (3a) are slit-shaped and can be inserted from above and from one side face by pin- or tab-shaped terminals. This construction prevents deformation of the terminals due to external force during transportation and mis-engagement with connector (5) of power board (4), and also prevents electrostatic breakdown of an element in the power module during handling as a result of directly touching the terminals. The module may comprise additional terminal blocks (2a to 2f).
