发明名称 Transistor clamping fixture
摘要 A removable transistor clamping fixture is disclosed which comprises an outer housing with a crosspiece configured to sit on top of the transistor. A U-shaped plunger straddles the crosspiece and has feet configured to rest on top of the transistor leads. One or more compression spring are placed between the top of the plunger and a coverplate so as to bias the plunger in a downward manner. When the clamping fixture is placed over a transistor, the crosspiece holds the transistor in place while the plunger feet apply a uniform downward pressure on the transistor leads of sufficient force to place the leads in electrical contact with an underlying printed circuit board. The clamping unit can be made largely from a plastic having a low dielectric constant to reduce the effect of the clamping fixture on the transistor's behavior.
