Abstract
The utility model belongs to low-voltage electrical technology, is related to a kind of dedicated permanent magnet mechanism of formula control and protective switch.The mechanism includes coil rack, the electromagnetic coil being mounted on coil rack, the dynamic iron core being inserted in electromagnetic coil, permanent magnet and magnetic yoke；The permanent magnet is annular, is placed in above electromagnetic coil；By outer yoke around surrounding on the outside of permanent magnet, permanent magnet lower end is connected closing with the lower yoke cover board below electromagnetic coil or all separates mouth；The inner yoke of annular is provided on the inside of permanent magnet, inner yoke upper end is mutually linked with outer yoke upper end, permanent magnet is enclosed in interior.Permanent magnet by being placed in the top of entire mechanism by the utility model, cooperate the magnetic yoke structure of optimization simultaneously, not only effectively reduce the height of entire mechanism, and longitudinal magnetize is changed to by original laterally magnetizing to the magnetizing direction of permanent-magnet material, traditional open magnetic circuit is closed simultaneously, effectively reduces influence of the magnetic circuit to external component.
Description
Technical field
The utility model belongs to low-voltage electrical technology, is related to a kind of dedicated permanent magnet mechanism of control and protective switch.
Background technique
Permanent magnet mechanism has more application (such as permanent-magnetic AC contact) in low voltage switch, but applies and controlling
On protective switch, still there are many problem and shortage, especially permanent magnet height problem, limit magneto switch in many fields
The application of conjunction.The permanent magnet mechanism for being conventionally used to control and protective switch generally includes electromagnetic coil, dynamic iron core and permanent magnet, and
With multiple magnetic yokes of permanent magnet cooperation.In existing structure, permanent magnet is generally arranged at below electromagnetic coil, and this structure makes iron
The stroke and length dimension of core are larger, and the total height of entire mechanism is also larger；For the height of reducing mechanism, the prior art also have by
Permanent magnet is placed in the middle part of electromagnetic coil, but the distribution mode of its magnetic yoke is unreasonable, thus whole height is still higher, some
In intellectualized reconstruction project, because being limited by switch cabinet, existing protective switch can not be directly replaced.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of compact-sized, whole height is low, and magnetic circuit is reasonable,
To the dedicated permanent magnet mechanism of control and protective switch that external action is small.
The dedicated permanent magnet mechanism of the utility model control and protective switch includes coil rack, is mounted on coil rack
Electromagnetic coil, the dynamic iron core, permanent magnet and the magnetic yoke that are inserted in electromagnetic coil；The permanent magnet is annular, is placed in electromagnetic wire
Circle top；By outer yoke around surrounding on the outside of permanent magnet, permanent magnet lower end and the lower yoke cover board that is located at below electromagnetic coil with
Contact or discontiguous mode are mutually connected；The inner yoke of annular, inner yoke upper end and outer yoke upper end are provided on the inside of permanent magnet
Mutually mutually it is connected in a manner of contacting or is discontiguous, permanent magnet is enclosed in interior.
The inner yoke upper end and outer yoke upper end are mutually linked by opposite flange.
The connector for the protrusion connecting with switch contact actuating mechanism is provided at the top of the dynamic iron core.
The utility model cooperates the magnetic yoke structure of optimization by the way that permanent magnet to be placed in the top of entire mechanism, no
The height of entire mechanism is only effectively reduced, and is magnetized to the magnetizing direction of permanent-magnet material by original longitudinal direction and is changed to laterally fill
Magnetic, while traditional open magnetic circuit is closed, effectively reduce influence of the magnetic circuit to external component.
Detailed description of the invention
Fig. 1 is the longitudinal sectional view of the utility model embodiment.
Specific embodiment
As shown, the mechanism includes coil rack 1, the electromagnetic coil being mounted on coil rack 2, is inserted in electromagnetic wire
Dynamic iron core 3 and permanent magnet 4 in circle；The permanent magnet 4 is the annular that multistage is composed, and is placed on electromagnetic coil 2
Side；The outside of permanent magnet 4 by outer yoke 5 around surrounding, 5 lower end of outer yoke and the lower yoke cover board 6 that is located at 2 lower section of electromagnetic coil with
Contact or discontiguous mode are mutually connected；The inner yoke 7 of annular, 7 upper end of inner yoke and outer yoke 5 are provided on the inside of permanent magnet 4
Upper end is mutually linked, and permanent magnet is enclosed in interior.Specifically, 5 ends pass through opposite flange 8 in 7 upper end of inner yoke and outer yoke
Mutually it is connected in a manner of contacting or is discontiguous.The protrusion for connecting with switch contact actuating mechanism is provided at the top of dynamic iron core 3
Connector 9.In the structure, electromagnetic coil, permanent magnet and each magnetic yoke arrange compact and form closed magnetic path, whole height ruler
It is very little small, external component is influenced small.
