Description
Technical Field
The utility model relates to an electromagnetic relay, especially a magnetic arc extinguishing relay.
Background
An electromagnetic relay is an electronic control device which uses smaller current and lower voltage to control larger current and higher voltage, is usually applied to an automatic control circuit, and plays the roles of automatic regulation, safety protection, circuit conversion and the like in the circuit. The existing small-sized electromagnetic relay is generally assembled by adopting a mode of combining a coil rack and a contact rack, a static contact is arranged in the contact rack, the coil rack and the contact rack are installed on a base plate, an upper cover covers the base plate, and the coil rack in the upper cover cannot be too large, so that the power of the electromagnetic relay cannot be improved.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a simple structure, small, convenient assembling to can the magnetic arc extinguishing relay of quick arc extinguishing.
In order to realize above mesh, the utility model discloses a magnetic arc extinguishing relay, including base, lid upper cover outside the base and electromagnetic system, moving contact, the static contact of setting on the base, electromagnetic system is connected with the moving contact, the base includes bottom plate and curb plate, and the curb plate encloses into contact installation cavity and electromagnetic installation cavity on the bottom plate, and the contact installation cavity sets up outside a corner of electromagnetic installation cavity upper end, and the junction of contact installation cavity and electromagnetic installation cavity forms the contact door, and electromagnetic system sets up in the electromagnetic installation cavity, and the moving contact front end passes the contact door and stretches into in the contact installation cavity, and the both sides of moving contact front end all are provided with the static contact, and the contact installation cavity forms static contact groove on the curb plate of static contact both sides, and the static contact both sides joint is in static contact groove, and the outside of contact installation cavity is provided with magnet.
The utility model discloses further set up to be provided with the magnet groove outside the contact installation cavity, magnet setting is in the magnet groove.
The utility model has the advantages that the base is provided with the contact mounting cavity and the electromagnetic mounting cavity, the electromagnetic system assembly and the contact assembly can be directly mounted on the base, the defect that the occupied base space is large due to the fact that the static contact of the original relay is mounted on the contact frame connected with the coil rack is overcome, more coils can be wound on the coil rack, rated power is improved, and automatic equipment can be conveniently adopted for assembly on the base with the static contact directly mounted; the magnet arranged on the outer side of the contact mounting cavity can bend the electric arc by magnetic force when the moving contact and the static contact are disconnected to generate the electric arc, so that the length of the electric arc is pulled, the electric arc is broken, and the electric arc is extinguished.
Drawings
Fig. 1 is a front view of the embodiment of the present invention with the upper cover removed.
Detailed Description
As shown in fig. 1, the embodiment of the present invention is a magnetic arc extinguishing relay, which comprises a base 1, an upper cover covering the base 1, an electromagnetic system 2, a moving contact 3, and a static contact 4, wherein the electromagnetic system 2, the moving contact 3, and the electromagnetic system 2 are disposed on the base 1, the base 1 comprises a bottom plate and a side plate, the side plate defines a contact mounting cavity 12 and an electromagnetic mounting cavity 11 on the bottom plate 1, the contact mounting cavity 12 is disposed outside a corner of the upper end of the electromagnetic mounting cavity 11, a contact door 14 is formed at the connection position of the contact mounting cavity 12 and the electromagnetic mounting cavity 11, the electromagnetic system 2 is disposed in the electromagnetic mounting cavity 11, the front end of the moving contact 3 passes through the contact door 14 and extends into the contact mounting cavity 12, both sides of the front end of the moving contact 3 are provided with the static contact 4, the contact mounting cavity 12 forms a static contact slot 15 on the side plate at both sides of the static contact 4, both sides of the static contact 4 are clamped in the static contact slot 15, a magnet groove 13 is arranged outside the contact mounting cavity 12, and a magnet 5 is arranged in the magnet groove 13.
