Terminal press-fitting device

A terminal press-fitting device in which a plurality of terminals are projected in a connector housing, and terminals of a connector having a staggered arrangement section of the terminals for which an arrangement position of the terminals in a lateral direction of the connector housing is set in a staggered manner are press-fitted into an insertion hole formed on a substrate, comprising:

• a first terminal restricting member on which a guide section for restricting a vertical displacement of the terminals by being introduced between the terminals along the lateral direction of the connector housing is provided;
• and
• a second terminal restricting member on which a guide section for restricting the lateral displacement of the terminals by 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 is provided,
• wherein a guide groove to which terminals arranged on an interior side of the connector housing are introduced is provided at a tip end portion of the guide portion of the first terminal restricting member positioned at the staggered arrangement section of the terminals.
