Description
Technical field
The utility model relates to a kind of contact component, particularly a kind of three-phase ac contactor conversion hysteria contact component.
Background technology
Contactor fast shut-off can exchange with direct current major loop and can connect the device with big current control circuit continually; often apply to motor also can be used as controlling work factory as control system establish electrical load such as standby ﹑ electricity hot device ﹑ machine-tool and various kinds electric power unit etc. to resembling ﹐; contactor can not only be connected and cut off circuit, but also has the effect of low-voltage release guard.Contactor control capability is large, is applicable to frequent operation and far distance controlled.It is one of critical elements in automatic control system.What at present three-phase ac contactor of the same type on the market only possessed single circuit cut-offs function, and do not possess the function simultaneously being carried out by two circuit changing, in engineer applied, usually two circuit need be changed, traditional contactor conveniently cannot realize external circuit conversion.
Summary of the invention
The purpose of this utility model, is to provide a kind of three-phase ac contactor conversion hysteria contact component.The utility model possesses three-phase alternating current load transfer function, and structure is simple, and superior performance, reliability is high.
The technical solution of the utility model: a kind of three-phase ac contactor conversion hysteria contact component, comprise pedestal, pedestal is provided with the first contact portion, cover plate and pushing block pedestal be equipped with, the second contact portion cover plate is equipped with, pushing block is equipped with the 3rd contact portion, the 3rd contact portion is between the first contact portion and the second contact portion, and pushing block is connected with drive link.
In aforementioned three-phase ac contactor conversion hysteria contact component, described first contact portion comprises first make contact, second contact portion comprises the second contact point, 3rd contact portion comprises the 3rd contact point and the 4th contact point, 4th contact point is corresponding with first make contact, and the 3rd contact point is corresponding with the second contact point.
In aforementioned three-phase ac contactor conversion hysteria contact component, described pedestal is provided with auxiliary end in contact part, and auxiliary end in contact part comprises the 5th contact point and bending boss, and the 5th contact point and pedestal are fitted, and bending boss is connected with the insulating trip of base bottom.
Compared with the prior art, the utility model is by the cover board installing the second contact portion, pedestal is installed the first contact portion, pushing block installs the 3rd contact portion, the 3rd contact point in 3rd contact portion and the 4th contact point are corresponding with the second contact point in the second contact portion and first make contact respectively, during initial condition, 3rd contact point and the second contact point are fitted, after product powers up action, 3rd contact point is separated with the second contact point, 4th contact point and first make contact laminating, thus realize the conversion of external load, compensate for the current single deficiency of cut-offfing function of contactor of the same type on the market.The utility model increases bending boss in auxiliary end in contact part, and bending boss immediate roof, in insulation spacer part, when exit is stressed, can effectively avoid static contact spring piece to be out of shape.The utility model also has implements structure feature simple and easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-first contact portion, 2-pedestal, 3-cover plate, 4-pushing block, 5-second contact portion, 6-the 3rd contact portion, 7-drive link, 8-electromagnetic system, 9-first make contact, 10-second contact point, 11-the 3rd contact point, 12-the 4th contact point, 13-assists end in contact part, 14-the 5th contact point, 15-bending boss, 16-insulating trip, 17-armature, 18-line lever, 19-stage clip, 20-coil, 21-yoke, 22-is unshakable in one's determination, 23-axle sleeve, 24-stage clip part.
Embodiment
Embodiment.A kind of three-phase ac contactor conversion hysteria contact component, form as shown in Figure 1, comprise pedestal 2, pedestal 2 is provided with the first contact portion 1, pedestal 2 is equipped with cover plate 3 and pushing block 4, cover plate 3 is equipped with the second contact portion 5, pushing block 4 is equipped with the 3rd contact portion 6,3rd contact portion 6 is between the first contact portion 1 and the second contact portion 5, and pushing block 4 is connected with drive link 7; Described first contact portion 1 comprises first make contact 9, second contact portion 5 comprises the second contact point 10,3rd contact portion 6 comprises the 3rd contact point 11 and the 4th contact point 12,4th contact point 12 is corresponding with first make contact 9,3rd contact point 11 is corresponding with the second contact point 10, described pedestal 2 is provided with auxiliary end in contact part 13, auxiliary end in contact part 13 comprises the 5th contact point 14 and bending boss 15,5th contact point 14 is fitted with pedestal 2, and bending boss 15 is connected with the insulating trip 16 bottom pedestal 2; Described drive link is connected with electromagnetic system 8, electromagnetic system 8 comprises iron core 22, yoke 21, coil 20, stage clip 19, line lever 18, armature 17, stage clip part 24 and axle sleeve 23, unshakable in one's determination 22 connect yoke 21, coil 20 loads in yoke 21, loads stage clip 19, line lever 18, armature 17, stage clip part 24 and axle sleeve 23 in yoke 21.
Operation principle: during initial condition, the 3rd contact point 11 in the 3rd contact portion 6 on pushing block 4 is fitted with the second contact point 10 in the second contact portion 5 on cover plate 3, normally-closed contact group is connected, when coil 20 encourages, armature 17 drives pushing block 4 to move under the effect of electromagnetic force, 3rd contact point 11 is separated with the second contact point 10, make the first make contact 9 in the first contact portion 1 fit with the 4th contact point 12 in the 3rd contact portion 6 on pushing block 4 simultaneously, normally opened contact group is connected, thus realizes the conversion of three-phase alternating current load.
