Description
Technical field
The present invention relates to relays.
Background technique
As relay, there is the relay (referring to patent document 1) with the mobile contact piece for being laminated with multiple leaf springs.It can
Moving contacting plate is connect with moving contact terminal.Moving contact, moving contact and fixed contact phase are installed in mobile contact on piece
It is right.In addition, being provided with extension in mobile contact on piece.Extension has relative to the side where moving contact to fixed contact
To the shape of stretching.On the matrix of bearing mobile contact piece, it is provided between the part opposite with extension and extension
Space is not interfered with the movable range with extension.
When flowing through high current between moving contact and fixed contact, effect has electromagnetic repulsion force on moving contact, should
The direction that electromagnetic repulsion force leaves towards moving contact to be made from fixed contact.But in above-mentioned relay, when movably connecing
When the super-high-current of contact upstream, electromagnetic repulsion force is acted between moving contact terminal and mobile contact piece, mobile contact piece is made to exist
The Direction distortion that moving contact is pressed to fixed contact.It is acted in a manner of pressing the moving contact to fixed contact
Electromagnetic repulsion force be more than the electromagnetic repulsion force that leave moving contact from fixed contact, inhibit moving contact to touch from fixed as a result,
Point leaves.

Problems to be solved by the invention
It is movable caused by electromagnetic repulsion force when the electric current for flowing through mobile contact piece increases but in above-mentioned relay
The deformation of contact chip may excessively increase.When the deformation of mobile contact piece is big, the power that press moving contact may be detached from
From moving contact towards the direction of fixed contact.In this case, due to dying down to the power of fixed contact pressing moving contact, so
A possibility that being separated there are moving contact from fixed contact.
Summary of the invention
Problem of the present invention is that providing a kind of point for being able to suppress moving contact and fixed contact when high current is powered
From relay.
A technical solution to solve project
The relay of a mode of the invention has moving contact portion, fixed contact portion, matrix.Moving contact portion has movable
Contact terminal, mobile contact piece, moving contact.Mobile contact piece is matched relatively in the prescribed direction relative to moving contact terminal
It sets, with moving contact terminal.Moving contact is connect with mobile contact piece.Fixed contact portion has fixed contact terminals and fixed touching
Point.Fixed contact terminals are relative to moving contact terminal configured separate in the prescribed direction.Fixed contact in the prescribed direction with
Moving contact terminal relative configuration, connect with fixed contact terminals.Matrix stores moving contact portion and fixed contact portion.Movably connect
Contact has multiple leaf springs.Multiple leaf springs are layered on top of each other configuration.Mobile contact piece includes to prescribed direction extension outstanding.Base
Body has the limiting unit opposite with extension.Fixed contact terminals have the first surface opposite with mobile contact piece and are located at the
The second surface of the opposite side on one surface.Restriction site more leans on mobile contact piece side in the second surface than fixed contact terminals.
When the electromagnetic repulsion force when being powered deforms mobile contact piece, by making to limit before multiple leaf springs all plastic deformation
Portion processed is contacted with extension, and the mode for limiting the deformation of mobile contact piece sets the distance between limiting unit and extension.
Matrix also can have recess portion that is opposite with extension and being recessed to prescribed direction.Limiting unit also may include in recessed
Portion.
It can also any feelings when moving contact is separated from fixed contact and when moving contact and fixed contact contact
At least part of condition, extension configures in recess portion.
Can also be when moving contact and fixed contact contact, at least part of extension is located at than fixed contact terminals
First surface more lean on second surface side.
It can also be than movable in the distance between the outer surface of the matrix of prescribed direction and limiting unit relative to restriction site
The distance between limiting unit and extension when contact is separated from fixed contact are big.
Matrix also can have the first opposite with extension in the prescribed direction medial surface, and limiting unit may be first
Medial surface.
Limiting unit may be from the first medial surface towards extension protrusion outstanding.
Matrix also can have second extended on the direction from the first medial surface towards extension from the first medial surface
Medial surface.Limiting unit may be the second medial surface.
Invention effect
In the present invention, when the electromagnetic repulsion force when being powered deforms mobile contact piece, by whole in multiple leaf springs
Before plastic deformation, limiting unit is contacted with extension, limits the deformation of mobile contact piece as a result,.Therefore, electricity when because being powered
Magnetic repulsion and make mobile contact piece deform when, in such a way that at least one of multiple leaf springs is not plastically deformed, pass through limitation
The deformation of portion's limitation mobile contact piece.Therefore, when high current is powered, inhibit the feelings that exceedingly substantially deform of mobile contact piece
Condition, also, at least one of multiple leaf springs maintains elastic force.Moving contact and fixed touching when thereby, it is possible to inhibit high current to be powered
The separation of point.
