Summary of the invention
The purpose of the present invention is to provide a kind of contact with grinding function, it is smaller to solve existing contact pressure,
The shortcomings that contact cannot be ground.
The technical scheme adopted by the invention is that a kind of contact with grinding function, is oppositely arranged quiet including two
Contact assembly is provided with the pull rod of inverted u-shaped between two static contact components, further includes two, pull rod that inverted u-shaped is arranged in
Moving contact component between side, moving contact component are located at the surface of two static contact components, the upper side of moving contact component
It is additionally provided with contact pressure leaf spring between the pull rod of inverted u-shaped, is provided with strip on two sides of the pull rod of inverted u-shaped
Hole, connecting shaft is provided between two strip holes and connecting shaft passes through moving contact component.
The features of the present invention also characterized in that
The position that the bottom surface of moving contact component is contacted with static contact component is provided with moving contact piece, the upper table of static contact component
The position that face is contacted with moving contact component is provided with static contact piece.
The shape of static contact piece and moving contact piece is any one in rectangle, circle or abnormity.
Static contact piece and the contact surface of moving contact piece are a plane or an arc surface.
The middle line of strip hole along its length and horizon bar direction angle at an acute angle.
The beneficial effects of the present invention are:
A kind of contact with grinding function of the invention, it is small in size, it is simple and compact for structure, it solves existing contact and connects
It cannot be ground when touching, the small disadvantage of contact pressure improves contact pressure, increases contact face, improve contact
Electrodynamical stability and contact reliability.

Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of contact with grinding function of the present invention, as shown in Figure 1, include two static contact components 1 being oppositely arranged,
The pull rod 2 of inverted u-shaped is provided between two static contact components 1, further include be arranged in inverted u-shaped 2 two sides of pull rod it
Between moving contact component 4, moving contact component 4 is located at the surface of two static contact components 1, the upper side of moving contact component 4 with
It is additionally provided with contact pressure leaf spring 5 between the pull rod 2 of inverted u-shaped, as shown in Fig. 2, on two sides of the pull rod 2 of inverted u-shaped
It is provided with strip hole 8, connecting shaft 3 is provided between two strip holes 8 and connecting shaft 3 passes through moving contact component 4；Strip hole 8
Middle line and horizon bar direction angle at an acute angle along its length, moving contact component 4 is as connecting shaft 3 is in the pull rod 2 of inverted u-shaped
It slides up and down, and because strip hole 8 has certain inclination angle, moving contact component 4 can break away in the activity of slide downward to one
It is dynamic.
The position that the bottom surface of moving contact component 4 is contacted with static contact component 1 is provided with moving contact piece 6, static contact component 1
The position that upper surface is contacted with moving contact component 4 is provided with static contact piece 7.
The shape of static contact piece 7 and moving contact piece 6 is any one in rectangle, circle or abnormity, and preferred square
Shape.
Static contact piece 7 and the contact surface of moving contact piece 6 are a plane or an arc surface, and preferred cambered surface.
A kind of contact with grinding function of the present invention, in order to avoid being hard between moving contact component 4 and static contact component 1
Property contact when contact assembly is damaged, it is therefore desirable to moving contact component 4 is movably connected within the pull rod 2 of inverted u-shaped,
After moving contact component 4 and static contact component 1 contact, moving contact component 4 can carry out grinding buffering thus with static contact component 1
Realize grinding contact.Preferably, contact pressure leaf spring 5 is between the pull rod 2 and moving contact component 4 of inverted u-shaped, and with dynamic touching
Head assembly 4 is contacted with the pull rod 2 of inverted u-shaped；Moving contact component 4 is connect by connecting shaft 3 with the pull rod 2 of inverted u-shaped, and with
The pull rod 2 of inverted u-shaped is up and down.There is boss in the 2 inside top face of pull rod of inverted u-shaped, for blocking contact pressure leaf spring 5.
As shown in figure 3, being attracting state schematic diagram at the beginning of a kind of contact with grinding function of the invention, work as inverted u-shaped
Pull rod 2 when moving downward, drive moving contact component 4 to move downward, the moving contact piece 6 of 4 two sides of moving contact component and two it is quiet
When the static contact piece 7 of contact assembly 1 contacts, circuit conducting.
As shown in figure 4, for a kind of schematic diagram of the contact fully closed condition with grinding function of the present invention, when U-shaped
The pull rod 2 of type continues to move downwardly to predetermined position, and moving contact component 4 does not continue to move downward at this time, moving contact component 4 with
Two static contact components 1 are in circuit on state, but connecting shaft 3 moves to top in advance in the inclined strip hole slot of pull rod 2
Positioning is set, while driving moving contact component 4 to a Slideslip, the moving contact piece of 4 two sides of moving contact component respectively with two stationary contacts
Static contact piece 7 in head assembly 1 contacts, and grinds mobile a distance.
Through the above way as can be seen that a kind of contact with grinding function of the present invention, simple and compact for structure, volume
Small, operating force is small, impact energy is small, contact bounce is small in closing course, and contact pressure is big, contact resistance is small, dynamic/static contact tool
There is grinding function and can be with self-cleaning.
