Abstract
The utility model discloses a base of an alternating current contactor, mainly solving the problem that a traditional contactor base cannot prevent ashes and object particles from entering into a framework. The base of the alternating current contactor is characterized in that a sideboard (2) is connected with a rib board (3) through a coaming (4); and the sideboard (2), the coaming (4) and the framework (5) which is arranged inside a seat body (1) encircles a cavity chamber with an enclosed periphery. The base of the alternating current contactor adopts a totally enclosed coaming structure, effectively prevents the ashes and the object particles from entering into the framework, and enables armature iron and a static iron core not to be influenced by the ashes and the object particles, thereby prolonging the service life of the contactor.
Description
Technical field:
The utility model relates to a kind of control apparatus, is specifically related to a kind of A.C. contactor, especially the A.C. contactor base.
Background technology:
A.C. contactor is widely used in the closed and disconnected of power equipment, and A.C. contactor mainly contains four parts and forms: (1) electromagnetic system comprises sucking coil, armature and static iron core; (2) contact system comprises that three secondary main contacts and two often open, two normally closed auxiliary contacts, the interlock mutually that connects together of it and armature; (3) arc-control device, the general bigger A.C. contactor of capacity all is provided with arc-control device, so that rapid breaking arc avoids burning out main contact; (4) insulator foot and annex, various springs, transmission mechanism, short-circuited conducting sleeve, binding post etc.At present, the base in this A.C. contactor is by the injection molded monolithic construction of insulation material, in the middle of it semi-enclosed coaming plate is arranged, and skeleton and static iron core are installed in coaming plate, is wound with coil on skeleton.When coil electricity, static iron core produces electromagnetic attraction, with the armature adhesive, and contact system and armature interlock, main contact is three movable contact springs, armature drives main contact operation, the closing of contact, thereby energized.When coil blackout, electromagnetic attraction disappears, and armature interlock part relies on the reaction force of spring and separates, and main contact is disconnected, and cuts off the electricity supply.When armature and static iron core adhesive, the alternating magnetic field that coil produces, dust, object particle etc. in the air there is stronger magnetic attraction, because the coaming plate on the base is a semi-closed state, can not intercept dust and object particle, dust, object particle directly enter in the skeleton from the open-mouth of coaming plate, and the one, jam armature has some setbacks armature movement; The 2nd, dust is bonded between armature and the static iron core, armature and static iron core do not reach the position, directly influence the closure of main contact.
The utility model content:
Existing contactor base can not intercept dust and object particle enters intraskeletal deficiency in order to overcome, the utility model provides a kind of A.C. contactor base, this A.C. contactor base adopts totally-enclosed coaming plate structure, effectively having intercepted dust and object particle enters in the skeleton, make armature and static iron core not be subjected to the influence of dust and object particle, the useful life of having improved contactor.
The technical solution of the utility model is: this A.C. contactor base comprises pedestal, has side plate and gusset on the pedestal, links to each other side plate, coaming plate and be installed on the chamber that skeleton in the pedestal surrounds a border seal between side plate and the gusset by coaming plate.
The end face of described side plate, gusset, coaming plate and skeleton is in same plane.
Described side plate, gusset and coaming plate and pedestal are injected into one.
The utlity model has following beneficial effect: owing to take such scheme, side plate, coaming plate and be installed on the chamber that skeleton in the pedestal surrounds a border seal, make dust and object particle can not enter in the skeleton, and then make armature and static iron core not be subjected to the influence of dust and object particle, the useful life of having improved contactor.Armature and static iron core are inserted in the described chamber, and armature is directly transferred to the outside with the heat that static iron core produces by the metal installation base plate that is connected on the pedestal and dispels the heat.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of pedestal 1 among Fig. 1;
Accompanying drawing 3 is sectional views of the present utility model.
1-pedestal among the figure, 2-side plate, 3-gusset, 4-coaming plate, 5-skeleton.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, this A.C. contactor base comprises pedestal 1, have side plate 2 and gusset 3 on the pedestal 1, link to each other by coaming plate 4 between side plate 2 and the gusset 3, side plate 2, coaming plate 4 and be installed on the chamber that skeleton 5 in the pedestal 1 surrounds a border seal, make dust and object particle can not enter in the skeleton 5, and then make armature and static iron core not be subjected to the influence of dust and object particle, the useful life of having improved contactor.Armature and static iron core are inserted in the described chamber, and armature is directly transferred to the outside with the heat that static iron core produces by the metal installation base plate that is connected on the pedestal 1 and dispels the heat.
By shown in Figure 1, the end face of described side plate 2, gusset 3, coaming plate 4 and skeleton 5 is in same plane.On this plane, connect metal base plate is installed, have better seal, dust and object particle can not be entered in the skeleton 5 from here.
By shown in Figure 2, described side plate 2, gusset 3 and coaming plate 4 are injected into one with pedestal 1.Easy to process, finished product is low.
Claims (3)
1. A.C. contactor base, comprise pedestal (1), have side plate (2) and gusset (3) on the pedestal (1), it is characterized in that: link to each other side plate (2), coaming plate (4) and be installed on the chamber that skeleton (5) in the pedestal (1) surrounds a border seal between side plate (2) and the gusset (3) by coaming plate (4).
2. A.C. contactor base according to claim 1 is characterized in that: the end face of side plate (2), gusset (3), coaming plate (4) and skeleton (5) is in same plane.
3. A.C. contactor base according to claim 1 and 2 is characterized in that: side plate (2), gusset (3) and coaming plate (4) are injected into one with pedestal (1).
