Abstract
The utility model relates to a contactor, including base, yoke, coil and clamp plate, in the base was arranged in to the yoke, the coil cup jointed in the yoke, and the clamp plate cup joints in the yoke to through the bolt fastening on the base, be equipped with first hole on the base, be equipped with the first bolster of a body structure, first bolster is arranged in on the base to supporting the yoke, being equipped with the recess that is used for placing first bolster on the base, first bolster adopts a body structure, at contactor operation in -process, can not produce relative movement, and is more stable, set up first bolster between yoke and base for the gravity of buffering yoke is avoided direct press on the base of yoke and is caused the wearing and tearing of yoke.
Description
Technical field
The utility model relates to a kind of electric equipment, particularly a kind of contactor.
Background technology
When after contactor coil energising, coil current can produce magnetic field, and the magnetic field of generation makes fixed core produce the dynamic iron core of electromagnetic attraction attraction, and drives the action of A.C. contactor point, and normally-closed contact disconnects, and normally opened contact closes, and both are interlocks.When the coil is de-energized, electromagnetic attraction disappears, and armature discharges under the effect of retracting spring, and contact is restored, and normally opened contact disconnects, and normally-closed contact closes.
Contactor at least comprises base, yoke and coil, should avoid direct contact between base and yoke, and yoke is worn and torn.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of contactor.
The technical scheme that the utility model adopts is: a kind of contactor, comprise base, yoke, coil and pressing plate, described yoke is placed in base, and coil is socketed in yoke, and pressing plate is socketed in yoke, and be bolted on base, base is provided with the first hole, is provided with the first bolster of integrative-structure, and described first bolster is placed on base, and against yoke, base is provided with the groove for placing the first bolster.
Be arranged with positioning boss in described groove, described first bolster is provided with the location hole corresponded, and the height of described positioning boss is lower than the hole depth of described location hole.
The side that described first bolster contacts with yoke is uniform-distribution with some boss.
Described first bolster adopts quality of rubber materials.
Described first bolster is rectangle.
Described first hole is placed in the middle of groove, and described first bolster is provided with the second hole coincided with the first hole.
The second bolster is provided with between yoke at pressing plate.
The beneficial effects of the utility model are:
1) the first bolster adopts integrative-structure, in contactor running, can not produce relative movement, more stable;
2) the first bolster being set between yoke and base, for cushioning the gravity of yoke, avoiding yoke to be directly pressed in wearing and tearing base causing yoke.
Accompanying drawing explanation
Fig. 1 be the utility model contactor partly cut open figure.
Fig. 2 is the structure chart of the utility model first bolster.
1-base, 11-first hole, 12-groove, 13-positioning boss, 2-yoke, 3-coil, 4-pressing plate, 5-first bolster, 51-location hole, 52-boss, 53-second hole, 6-second bolster.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As depicted in figs. 1 and 2, a kind of contactor, comprise base 1, yoke 2, coil 3 and pressing plate 4, described yoke 2 is placed in base 1, coil 3 is socketed in yoke 2, pressing plate 4 is socketed in yoke 2, and is bolted on base 1, and base 1 is provided with the first hole 11, be provided with the first bolster 5 of integrative-structure, described first bolster 5 is placed on base 1, and against yoke 2, base 1 is provided with the groove 12 for placing the first bolster 5, first bolster 5 adopts integrative-structure, in contactor running, can not relative movement be produced, more stable; First bolster 5 being set between yoke 2 and base 1, for cushioning the gravity of yoke 2, avoiding yoke 2 to be directly pressed in wearing and tearing base 1 causing yoke 2.
Positioning boss 13 is arranged with in described groove 12, described first bolster 5 is provided with the location hole 51 corresponded, location hole 51 is socketed on positioning boss 13, first bolster 5 is positioned on base 1, first bolster 5 is carried out to the location of X-direction and Y-direction, this positioning boss 13 height, lower than the hole depth of location hole 51, prevents positioning boss 13 convex in the first bolster 5, positioning boss 13 directly contacts with yoke 2, thus makes the first bolster 5 lose buffer effect.
The side that described first bolster 5 contacts with yoke 2 is uniform-distribution with some boss 52, boss 52 contacts with yoke 2, owing to having space between boss 52, in contactor running, the heat that yoke 2 produces can be gone out by these interstitial flow, plays the effect of heat radiation.
Described first bolster 5 adopts quality of rubber materials, increases the shock-absorbing capacity of the first bolster 5.
Described first bolster 5 is rectangle, and the shape with yoke 2 is close, and can save material, conserve space, makes structure compacter.
The first hole 11 of being provided with in the middle of groove 12 on base 1 is the heat radiations for contactor, therefore must the second hole 53 corresponded be set on the first bolster 5, make the heat radiation of contactor change to the second hole 53 from the first hole 11, the heat of contactor has delivery outlet all the time.
Be provided with the second bolster 6 at pressing plate 4 with between yoke 2, for cushioning the gravity of pressing plate 4, avoid the micro-movement between pressing plate 4 and yoke 2 and causing the wearing and tearing of yoke 2.
Below described by reference to the accompanying drawings embodiment is only preferred implementation of the present utility model, and the restriction not to protection range of the present utility model, and any improvement done based on the utility model spirit all ought within the utility model protection range.
