Abstract
The utility model relates to a relay of a basic electric element, which structurally solves a problem of load capacity of a relay contact. The utility model is composed of an electromagnetic system, a contact system, and a base. The electromagnetic system is characterized in that a movable contact is combined by a striking contact and an active contact; compared with the active contact, the striking contact can always and firstly touch a fixed contact; when separation is conducted, the striking contact is always later than the active contact; the external parts of the movable and the fixed contacts are covered with an arc insulating device which causes the movable and the fixed contacts to be separated with other components of the relay, and the original touch reed type structure is broken to be a rotary and shock-proof contact type structure to improve electric load. The utility model is suitable for being used as an automatic changeover switch of great current in a control system.
Description
The utility model relates to essential electronic element, particularly relay.
Electromagnetic system that existing electromagnetic relay is is mainly connected and composed by certain process means such as riveting dress, welding, screw, rivet by discrete parts such as armature, yoke, moving contact point, quiet contact point, reed, recovery extension springs and contact system and pedestal are formed.Because electromagnetic relay " lead to " or " break " can make during electric current greatly and occur electric arc between moving contact and fixed contact and burnt in the contact, even makes the reed deliquescing and influence the reliability and the useful life of electromagnetic relay.
The purpose of this utility model is by the structure of modification to electromagnetic relay, and a kind of compact conformation, the easy raising of the assembling high-current relay in useful life is provided.
The utility model is made up of electromagnetic system, contact system and pedestal, it is characterized in that moving contact is composed in parallel by striking contact and active point, the striking contact always touches fixed contact earlier than active contact, and when separating the back in the active contact, an arc insulating apparatus in dynamic and static contact outer cup, dynamic and static contact and other parts of relay are separated, and break the former reed-type structure of touching for rotating shockproof contact structure.
Striking contact and arc cover structure make initiatively because the utility model has adopted, fixed contact has obtained protection; rotate shockproof contact and solved moving spring heating deliquescing again; the pressure of dynamic and static contact is guaranteed, thereby has improved the reliability and the useful life of relay.
What accompanying drawing was represented is to represent electromagnetic system (1), armature (2), pedestal (3), arc insulating apparatus (4), insulating part (5), stage clip (6), rotation electric-conductor (7), peg (8), striking contact (9), active contact (10), quiet contact point (11) among structural representation of the present utility model, the figure.
Realize that best way of the present utility model is that rotation electric-conductor (7) is connect it and insulating part (5) with peg (8), its afterbody is used down stage clip (6) and is clipped, and it is that the material of more anti-fusing is made than the active thick 0.3～0.5mm in contact that the weldering of its head is knotted initiatively contact (10) and stressed mobilizable striking contact (9), striking contact.Arc insulating apparatus (4) in dynamic and static contact outer cup is mounted on the base (3), and this assembling is simple and easy accurate again.Adopt a plurality of a kind of devices of the present utility model to work simultaneously, can constitute corresponding many groups contact relay.
The utility model is applicable in the control system and uses as big electric current automatic transfer switch.
Claims (1)
1, the electromagnetic relay that makes up by electromagnetic system (1), armature (2), pedestal (3), arc insulating apparatus (4), insulating part (5), stage clip (6), rotation electric-conductor (7), peg (8), striking contact (9), active contact (10) and quiet contact point (11), it is characterized in that having a rotation electric-conductor (7), the active contact (10) that on its head, has movable striking contact (9) of stressed energy and weldering to be knotted, its afterbody is used down stage clip (6) and is clipped; The striking contact is that the material of more anti-fusing is made than the active thick 0.3～0.5mm in contact, striking contact stressed energy automatic movable; The arc-control device that is contained on the pedestal (3) covers on outside, dynamic and static contact, keeps apart magnetic system.
