Abstract
The utility model relates to an iron core limiting part of an alternating current contactor. The limiting part is a thin type strip-shaped component, and is characterized in that an arc-shaped bulge is arranged in the middle of one surface of the limiting part, bulges are arranged at two ends of the surface, and grooves corresponding to the arc-shaped bulge and the bulges at the two ends are arranged on the other surface of the limiting part. The limiting part is inserted in a hole in the middle of a fixed iron core so as to limit the fixed iron core, two ends of the limiting part are inserted into the corresponding grooves of a positioning block, after being connected, the positioning block, the fixed iron core and the limiting part are put in a base, and a coil is arranged above the positioning block so as to press the positioning block. The limiting part not only can save materials and facilitate machining, but also can improve the vibration of the fixed iron core.
Description
Technical field
The utility model relates to the limited part of iron core in a kind of A.C. contactor, and the position-limit mechanism of iron core in the A.C. contactor.
Background technology
A.C. contactor generally comprises secured core and movable core, wherein secured core need be fixed in the base, the location structure of secured core, generally need pass iron core with a limited part, the two ends of limited part are fixed with piece, after putting into the base location, the piece of pushing down the limited part two ends with coil fixes iron core, the limited part general thickness is more than 1.2mm and complex structure, and processing is got up also very inconvenient, general limited part can not improve the vibration of iron core, causes the unnecessary vibration of secured core in the running of A.C. contactor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to process and can prevent the limited part of A.C. contactor iron core of the vibration that secured core is unnecessary and the position-limit mechanism of this A.C. contactor iron core at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of iron core limited part of A.C. contactor, described limited part is a slim elongated member, it is characterized in that: the wherein centre position of one side of described limited part has the circular arc projection, two ends have projection, and the another side of described limited part has the corresponding groove of projection with described circular arc projection and two ends.Such limited part is not only saved material, convenient processing, and can improve the vibration of secured core.
Preferably, the projection at described two ends is a square protrusion.
A kind of position-limit mechanism with A.C. contactor secured core of above-mentioned locating part, it is characterized in that: secured core is limited in the hole that described limited part is inserted in the middle of the secured core, insert in the corresponding groove of locating piece at the two ends of described limited part, locating piece after the connection, secured core and limited part are put into base, put into coil and push down described locating piece above institute's locating piece.
In order to cushion the vibration of described secured core, also be lined with bolster between described secured core and the base.
Preferably, described locating part has the one side of projection at circular arc projection and two ends towards the back side of described secured core.
Compared with prior art, advantage of the present utility model is: this limited part is not only simple in structure, easy to process, and it has saved material, has reduced cost.And after this limited part limits this iron core, can reduce the unnecessary vibration of iron core, improve the performance of A.C. contactor.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Limited part of the present utility model, shown in Fig. 1-5, limited part 2 is fixed in the secured core 1 among Fig. 1, in the hole 11 in the middle of the limited part 2 insertion secured cores 1, the two ends of limited part 2 are inserted in the groove 31 of locating piece 3, and secured core 1 and limited part 2 and locating piece 3 are put into base, and locating piece 3 is used for limited part 2 is fixed on base.In order to alleviate the vibration of this secured core 1, after bolster can also being placed with on the base, put into secured core 1 again.After secured core 1 put into base, the locating piece 3 of pushing down the limited part both sides with coil was fixed on secured core 1 in the base.
Described limited part 2 has projection for mask one by one, and another side has the slim elongated member of identical shaped groove.The centre of this limited part one side has a circular arc projection 21, two ends also have square protrusion 22, the height of described circular arc projection 21 is identical with the height H of two ends projection 22, limited part has the one side of square protrusion 22 at arc-shaped protrusions 21 and two ends towards the back side of secured core 1, and the another side of described limited part 2 also has corresponding grooves with respect to the square protrusion 22 at circular arc projection 21 and two ends.This limited part 2 that the projection 22 at two ends makes fixes with locating piece 3, and middle circular arc projection 21 makes limited part 2 and secured core 1 fix, and the shape of this limited part 2 can be used to alleviate the unnecessary vibration of secured core 1.Simultaneously such limited part 2 has not only been fixed secured core, has alleviated the vibration of secured core, but also has saved material, saved cost, and has reduced the difficulty of processing, has improved production efficiency.
In addition to the implementation, the utility model also includes other execution modes, and the technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection range of the utility model claim.
