Claims

[Scope of utility model registration request]

A connecting piece to which both ends of the coil are connected is attached to the collar of the coil bobbin on which the coil is wound, and a spring piece fixed to the terminal plate of the coil terminal that connects the current-carrying wire to the coil is attached to the connecting piece with elasticity. In an electromagnetic contactor that electrically connects a terminal plate and a connecting piece through contact, the central part between the base end of the spring piece that is fixed to the terminal plate and the tip that contacts the connecting piece is called the tip part. An electromagnetic contactor characterized in that the terminal plate is formed obliquely so that the end surface touches near the center line of the terminal plate, and the tip is divided by a slit having a length that provides appropriate rigidity to the tip.
