Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, and for people provide a kind of structure simple, the Horizontal electric magnetic relay of compact, controls the break-make of high voltage.
Technical solution adopted in the utility model is for achieving the above object: this Horizontal electric magnetic relay comprises the housing with base, the front end of housing is provided with end cap, the sidewall of housing is fitted with two low tension terminals and two high tension terminals, in the rear end of insulation shell, coil is installed, two exits of coil are connected with corresponding low tension terminal respectively, the centre bore rear end of coil is provided with static iron core, the centre bore front end activity of coil is fitted with dynamic iron core, described static iron core is fixed on the aft bulkhead of housing, described dynamic iron core is provided with the shaft shoulder, at the shaft shoulder, place is set with mount pad, mount pad is embedded with movable contact spring, two contacts on movable contact spring lay respectively at the front side of corresponding high tension terminal, mount pad spring is supported with between described coil and mount pad, the front end of described dynamic iron core offers caulking groove, jump ring is provided with in caulking groove, front springs is provided with between described jump ring and mount pad.
The sidewall of described housing is provided with insulating plug, and high tension terminal is interspersed in the endoporus of insulating plug, between high tension terminal and the inwall of housing, be provided with insulation spacer, and high tension terminal is installed with clamp nut, and this clamp nut is positioned at the outside of insulating plug.
Pad is provided with between described coil and high tension terminal.
Described end cap and housing fasten and flanging.
Described high tension terminal is positioned at the left and right sides of housing.
As long as the utility model connects low tension terminal, just can make coil electricity, make iron core have magnetic by electromagnetic induction, thus move after making iron core and static iron core adhesive, the contact now on movable contact spring and high tension terminal offset, and make two high tension terminal conductings.High tension terminal of the present utility model is positioned at the left and right sides of housing, there will not be and has foreign object to fall between two high tension terminals, causes the phenomenon of the unexpected conducting of two high tension terminals.And the good insulating of high tension terminal and housing, under 1200V voltage, the electric leakage between high tension terminal and shell is less than 1mA, has the advantage that structure is simple, easy for installation.
