Description

Idol main contacts contactor

The utility model relates to the induction type relay technical field.

Induction type relay in the past, main contacts have 1 or 3, and each main contacts has 2 fixed contacts and 2 moving contacts, and 2 moving contacts link to each other and operated by the clutch support of electromagnetism actuating mechanism, do not have under the electric situation for often opening.This relay, specificity is poor, is not easy to be used in the automatic transfer equipment of duplex feeding cost height, purposes narrow range.

The purpose of this utility model provides a kind of even main contacts contactor, and its purposes is wide, and specificity is strong, can conveniently be used for the duplex feeding automatic transfer equipment, its compact conformation, and cost is low.

The utility model is achieved in that

A kind of main contacts contactor, comprise the electromagnetism actuating mechanism, it is characterized in that having housing and/or base, main contacts has 2 or 4, and each main contacts has 2 fixed contacts and 2 moving contacts, and 2 fixed contacts link to each other with housing or base by insulator respectively, 2 fixed contacts are connected to binding post respectively, 2 moving contacts link to each other by conducting strip, and conducting strip links to each other by the clutch support of insulator and electromagnetism actuating mechanism, and main contacts is Chang Kai or is normally closed.Promptly under no electric situation, main contacts is often opened, and has under the electric situation, and main contacts is connected.

On the basis of the above, can be added with the auxiliary contact structure again, preferably have 2 auxiliary quiet moving normally closed normally opened contacts, each auxiliary contact divides two parts up and down, there are 2 fixed contacts and 2 moving contacts in top, these 2 fixed contacts link to each other with housing or base by insulator respectively, and 2 moving contacts link to each other by conducting strip, and conducting strip links to each other by the clutch support of insulator and electromagnetism movement structure; There are 2 moving contacts and 2 fixed contacts in the lower part, 2 moving contacts link to each other by conducting strip, conducting strip links to each other or directly links to each other with the conducting strip on top by the clutch support of insulator and electromagnetism actuating mechanism, 2 fixed contacts link to each other with housing or base respectively by insulator, four fixed contacts are connected with binding post respectively, sound contact, top is normally closed or often is opens, and sound contact, lower part is Chang Kai or is normally closed.Promptly do not have when electric, sound contact, top is normally closed, and sound contact, lower part is for often opening, when electricity is arranged, otherwise.Reliable for contacting, spring preferably is housed between two conducting strips.

The structure of another kind of main contacts contactor is, comprise electromagnetism actuating mechanism and housing, it is characterized in that main contacts has 2, each main contacts divides two parts up and down, top comprises 2 fixed contacts and 2 moving contacts, 2 moving contacts link to each other by conducting strip, and conducting strip links to each other by the clutch support of insulator and electromagnetism actuating mechanism; The lower part comprises 2 moving contacts and 2 fixed contacts, 2 moving contacts link to each other by conducting strip, conducting strip links to each other or directly links to each other with the conducting strip on top by the clutch support of insulator and electromagnetism actuating mechanism, above-mentioned four fixed contacts are connected with binding post respectively, sound contact, top is normally closed or often is opens, and sound contact, lower part is Chang Kai or is normally closed.Do not have promptly that sound contact in top is normally closed under the electric situation, the sound contact of lower part is for often opening, otherwise when electricity is arranged.

Reliable for contacting, be connected with spring by insulator between best 2 conducting strips.

For the ease of wiring, preferably the binding post on the fixed contact of each fixed contact above the main contacts and bottom correspondence is in different axial location.

On the said structure basis, can add the auxiliary contact structure, preferably have 2 auxiliary quiet moving normally closed normally opened contacts, its structure is with in above-mentioned the various main contacts structures of class any.

The utlity model has the characteristics that purposes is wide, specificity is strong, can be used in the duplex feeding automatic transfer equipment, its cost is low, compact conformation, and circuit is economized, and is convenient to realize the control automation.Also can replace knife switch, safe in utilization, the life-span is long, total cost is low, work rapidly, conversion is fast.Also can make manual or automatic switch in other electrical equipment uses.
