Abstract
A method of incorporating compliant pins in a pressure sensor that uses PCB (printed circuit board) and is press fitted into the compliant pins. The compliant pins are made in the leadframe and the leadframes are molded into the plastic housing. The PCB is press fitted to the leadframe/housing assembly.
Claims20
A method of incorporating a compliant pin in a pressure sensor, comprising:
- molding at least one leadframe into a plastic housing in order to provide a leadframe and housing assembly composed of said at least one leadframe and said plastic housing;
- configuring at least one compliant pin in said at least one leadframe;
- connecting a printed circuit board to said leadframe and housing assembly via said at least one compliant pin, such that said at least one compliant pin provides a force connection for press fitting said printed circuit board to said leadframe wherein said force connection is achieved by utilizing said at least one compliant pin formed with a tab in the pin portion which is captured in the molded body portion, thereby providing a pressure sensor supported by said at least one leadframe, said at least compliant pin, said printed circuit bard and said plastic housing.
The method of claim l wherein said at least one leadframe comprises a metal leadframe and wherein connecting said printed circuit board to said leadframe and housing assembly via said at least one compliant pin further comprises force connecting said printed circuit board to said leadframe and housing assembly.
The method of claim l wherein said at least one leadframe comprises a metal leadframe and wherein connecting said printed circuit board to said leadframe and housing assembly via said at least one compliant pin further comprises force connecting said printed circuit board to said leadframe and housing assembly.
A method of incorporating a compliant pin in a pressure sensor, comprising:
- molding at least one leadframe into a plastic housing in order to provide a leadframe and housing assembly composed of said at least one leadframe and said plastic housing, wherein said at least one leadframe comprises a metal leadframe;
- configuring at least one compliant pin in said at least one leadframe;
- connecting a printed circuit board to said leadframe and housing assembly via said at least one compliant pin, such that said at least one compliant pin provides a force connection for press fitting said printed circuit board to said leadframe wherein said force connection is achieved by utilizing said at least one compliant pin formed with a tab in the pin portion which is captured in the molded body portion, thereby providing a pressure sensor supported by said at least one leadframe, said at least compliant pin, said printed circuit bard and said plastic housing.
A pressure sensor apparatus, comprising:
- at least one leadframe molded into a plastic housing in order to provide a leadframe and housing assembly composed of said at least one leadframe and said plastic housing;
- at least one compliant pin configured in said at least one leadframe;
- a printed circuit board connected to said leadframe and housing assembly via said at least one compliant pin, such that said at least one compliant pin provides a force connection for press fitting said printed circuit board to said leadframe wherein said force connection is achieved by utilizing said at least one compliant pin formed with a tab in the pin portion which is captured in the molded body portion, thereby providing a pressure sensor supported by said at least one leadframe, said at least compliant pin, said printed circuit bard and said plastic housing.
The apparatus of claim l2 wherein said at least one leadframe comprises a metal leadframe and wherein connecting said printed circuit board to said leadframe and housing assembly via said at least one compliant pin further comprises force connecting said printed circuit board to said leadframe and housing assembly.
A pressure sensor apparatus, comprising:
- at least one leadframe;
- a plastic housing, wherein said at least one leadframe is molded into said plastic housing in order to provide a leadframe and housing assembly composed of said at least one leadframe and said plastic housing, said at least one leadframe comprising a metal leadframe;
- at least one compliant pin configured in said at least one leadframe;
- and
- a printed circuit board connected to said leadframe and housing assembly via said at least one compliant pin, such that said at least one compliant pin provides a force connection for press fitting said printed circuit board to said leadframe wherein said force connection is achieved by utilizing said at least one compliant pin formed with a tab in the pin portion which is captured in the molded body portion, thereby providing a pressure sensor supported by said at least one leadframe, said at least compliant pin, said printed circuit bard and said plastic housing.
