Abstract
The utility model discloses an alternating-current contactor iron core, which can effectively solve the problem of easy scatteration of the conventional alternating-current contactor iron core. The alternating-current contactor iron core comprises a plurality of E-shaped silicon-steel sheets. Each E-shaped silicon-steel sheet comprises a transverse iron core, wherein a vertical iron core is respectively arranged at the left end, the middle and the right end of the transverse iron core, fastening devices are respectively arranged at the upper parts of the left end vertical iron core and the right end vertical iron core, at least one fastening device is arranged on the transverse iron core, and a fastening device is also arranged in the middle vertical iron core. The alternating-current contactor iron core is additionally provided with the fastening device on the middle part vertical iron core, so as to effectively prevent the iron core from deconcentrating and prolong the service life of the product.
Description
Technical field
The utility model relates to a kind of A.C. contactor iron core.
Background technology
A.C. contactor is to be widely used as cut-offfing and control circuit of electric power.It utilizes main contact to open and close circuit, carries out control command with auxiliary contact.Main contact generally has only normal opened contact, and auxiliary contact often has two pairs of contacts with Chang Kai and normally closed function.A.C. contactor can be divided into electromagnetic type again, three kinds of magneto and vacuum type, electromagnetic AC contactor mainly is made up of electromagnetic system, contact system, arc quenching system and other part, electromagnetic system: electromagnetic system comprises solenoid and iron core, be the important component part of contactor, rely on it to drive the closure and the disconnection of contact.The iron core of existing electromagnetic AC contactor mainly adopts the silicon steel sheet of multi-disc E shape to be arranged in together to form, and runs into that silicon steel sheet scatters and the normal use that has influence on A.C. contactor through regular meeting in the actual use.
The utility model content
The purpose of this utility model is to provide a kind of A.C. contactor iron core, can effectively solve the problem that the iron core of existing A.C. contactor scatters easily.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of A.C. contactor iron core, comprise some E shape silicon steel sheets, described E shape silicon steel sheet comprises a horizontal iron core, the left end of described horizontal iron core, middle part, right-hand member are respectively equipped with a vertical iron core, the top of the vertical iron core of described left end, the vertical iron core of right-hand member is provided with tightening device, described horizontal iron core is provided with at least one tightening device, also is provided with tightening device on the vertical iron core in described middle part.
Preferably, described tightening device is a rivet; Tightening device commonly used, easy to use, the price material benefit.
Preferably, described horizontal iron core is provided with two tightening devices; Laterally iron core is longer, adopts two tightening devices more firm.
Compared with prior art, the utility model has the advantages that: on the vertical iron core in middle part, install tightening device additional, can prevent effectively that iron core from scattering, prolong product useful life.
