Description
Technical field
The utility model relates to a kind of relay contact system of resisting electrodynamic repulsion force between contact.
Background technology
Relay is the contact and the separated control realizing circuit connecting and disconnecting by two contacts in contact system.When two contacts contact, circuit is connected moment, and great short circuit current is carried in two contacts, form thus the electrodynamic repulsion force that impels two contact separation, and short circuit current is larger, and electrodynamic repulsion force is larger, and the threat that destroys two contact contact reliabilities is larger; When the closing of contact power being provided by shell fragment or electromagnetic system is not enough to resist the electrodynamic repulsion force between contact, can there is two contacts separated contact bouncing phenomenon in short-term, and be attended by hard arc, by hard arc, produced moment high temperature very easily melting burn contact.Therefore, the electrodynamic repulsion force between contact, not only can reduce the functional reliability of relay, but also can cause burning of relay contact, has great destruction.
Summary of the invention
The purpose of this utility model is to provide a kind of relay contact system of resisting electrodynamic repulsion force between contact, makes the relay with this contact system can stop electrodynamic repulsion force to produce destruction.
For achieving the above object, technical solution adopted in the utility model is: a kind of relay contact system, and first conducting strip one end is free end, the other end is link; First shell fragment one end is free end, and its free end is provided with the first contact, and the other end is link; The first conducting strip is connected with the first shell fragment link, it is characterized by: the first conducting strip is that free end direction is identical with the first shell fragment free end in the same side of link, and both form an overlapping and gapped zig-zag type structure of area; In like manner, the second conducting strip, the second shell fragment (its free end is provided with the second contact) also form an overlapping and gapped second zig-zag type structure of area; The connection by the first contact, the second contact of two zig-zag types is with separated, thereby forms two interconnective a kind of relay contact systems of zig-zag type.
Adopt the relay contact system of said structure, when the first contact contacts with the second contact, during loaded current conduction, the first conducting strip is contrary with current trend in the first shell fragment, the second conducting strip is contrary with current trend in the second shell fragment, according to producing the principle of the long-range navigation magnetic force mutually repelling between reverse current, be positioned at the first contact on the first shell fragment by the long-range navigation magnetic force repelling being mutually subject to from the first conducting strip, be positioned at the second contact on the second shell fragment by the long-range navigation magnetic force repelling being mutually subject to from the second conducting strip, thereby it is more firm that the first contact is contacted with the second contact, and electric current is larger, long-range navigation magnetic force is larger, two contact contacts are more firm, therefore be enough to resist the electrodynamic repulsion force between contact.
Say further, when the first contact is connected energising with the second contact, the electromagnetic repulsion force that the zig-zag type structure current opposite in direction that the first conducting strip and the first shell fragment form produces, the first closure force direction being applied on the second contact with the first contact is identical, and electromagnetic repulsion force increases the first contact to the closing force between the second contact; The electromagnetic repulsion force that the zig-zag type structure current opposite in direction that in like manner the second conducting strip and the second shell fragment form produces, the first closure force direction being applied on the first contact with the second contact is identical, is also that electromagnetic repulsion force increases the second contact to the closing force between the first contact.
First closure power between two contacts, can be produced by the first shell fragment or the second shell fragment self deformation, and the power that also can be applied on the first shell fragment, the first contact or the second shell fragment, the second contact by external parts produces.
The first shell fragment and the second shell fragment are soft movable conductor, and they can be under external force, and the zig-zag type link of take is separately done and rotated and deformation action as axle, thereby the first contact produces and is connected with separated with the second contact.
Two zig-zag type structures can parallel reversed arrangement, take contact to form origin symmetry as initial point; Also can arrange symmetrical with X-axis or Y-axis by parallel forward; Also can vertical arrangement be the first shell fragment and the second shell fragment spatial vertical, or other structures that form with two zig-zag type structures.
The utility model is novel in design, rational in infrastructure, utilize the long-range navigation magnetic force producing between reverse current to increase the closing force between two contacts, can effectively resist the electrodynamic repulsion force between two contacts, make to have relay of the present utility model and can eliminate the destroying infection that causes contact bouncing, burns because of electrodynamic repulsion force.
