Patent ID: 7134191

Claim:
A terminal press-fitting device in combination with a connector that includes a connector housing having a plurality of terminals and a substrate that includes a plurality of insertion holes, where the terminal press-fitting device press-fits each terminal of the connector into a respective insertion hole of the substrate, in a vertical direction of the terminal and connector housing, and where the plurality of terminals includes a staggered arrangement section of terminals in which an arrangement of the terminals in a lateral direction of the connector housing is set in a staggered manner, the terminal press-fitting device comprising: a first terminal restricting member having a guide section that restricts vertical displacement of the terminals, the first terminal restricting member being introduced between the terminals along the lateral direction of the connector housing; and a second terminal restricting member, separate from the first terminal restricting member, and having a guide section that restricts lateral displacement of the terminals, the second terminal restricting member being introduced between the terminals along the vertical direction of the connector housing in an upper or lower part of the first terminal restricting member, wherein a tip end portion of a guide portion of the first terminal restricting member includes a guide groove that receives a terminal arranged on an interior side of the connector housing in the staggered arrangement section of the terminals.
