Description
Technical field
The utility model relates to a kind of electromagnetic relay, particularly relates to a kind of magnetic effect high, the electromagnetic relay of stable performance.
Background technology
Electromagnetic relay is the electric current that a kind of use is less, lower voltage removes the automatic switch controlling larger electric current, higher voltage.It realizes this switching function is by being arranged at inner electromagnet, by passing into small electric stream to magnet spool, electromagnet is made to produce magnetic field, utilize the generation in magnetic field or disappearance and adhesive or unclamp movable iron, and then order about adhesive or disconnection between electroconductive elastic sheet by movable iron, realize the conducting to big current loop.But, the armature of existing electromagnetic relay generally adopts non-resilient base spacing, its one end is positioned at the attracted position of iron core, the other end is connected with moving part, this makes the pole-face of armature and electromagnet not fit completely, thus it is extremely low to make the magnetic of electromagnet imitate, therefore, the magnetic force of iron core adhesive armature is less; And when armature does not have accurate limit, make iron core can not stably adhesive armature, cause the unstable properties of electromagnetic relay.
Utility model content
It is high that the purpose of this utility model is to provide a kind of magnetic to imitate, the electromagnetic relay of stable performance.
To achieve these goals, the electromagnetic relay that the utility model provides comprises support, electromagnet, armature, moving part, spring plate, quiet shell fragment and two-terminal, described armature is bending structure, one end of described armature is positioned at an end face of described electromagnet, another proper side to the U-shaped iron core of described electromagnet of described armature, wherein, described electromagnetic relay also comprises the positive stop spring plate of the bending place being arranged at described armature, the bending place that described positive stop spring plate is flexibly resisted against described armature forms shaft axis, with the end face making one end of described armature be affixed on described electromagnet, during the other end of armature described in the energising of described electromagnet and adhesive, described armature rotates with described shaft axis and drives described moving part, and then drives described spring plate to contact at described quiet shell fragment.
Compared with prior art, the utility model arranges positive stop spring plate in the bending place of described armature, by utilizing the elastic force of described positive stop spring plate, one end of described armature is pressed on the end face of described electromagnet, because armature is more fitted the end face of described electromagnet, the magnetic field effect that electromagnet produces is better, therefore, the utility model can improve magnetic effect effectively, thus armature described in the better adhesive of energy; In addition, because described positive stop spring plate and supporting of described armature locate formation one shaft axis, therefore, when described electromagnetic actuation armature, described armature can swing around described shaft axis, is conducive to described armature fast reaction, improves the stability of electromagnetic relay work.
Preferably, described support is provided with mount pad in the position corresponding with the bending place of described armature, and described positive stop spring plate is installed on described mount pad.Described positive stop spring plate can be fixed by described mount pad, prevents it to be shifted.
Particularly, described mount pad offers inserting groove, and described positive stop spring plate is plugged in described inserting groove.Described inserting groove can make described positive stop spring plate can be installed on described mount pad quickly and easily.
More specifically, described positive stop spring plate has installation sheet and flexure strip, and described installation sheet is plugged in described inserting groove, and described flexure strip stretches out described inserting groove and is resisted against the bending place of described armature.
Preferably, described terminal has the first Plug Division, the second Plug Division and connecting portion, first side of the lower end of described first Plug Division is unsettled, and the second side of the lower end of described first Plug Division is connected with the side of described connecting portion, and described second Plug Division is connected with the opposite side of described connecting portion.
Particularly, the first rib is extended to the below of described first side in the side of described connecting portion, and described first rib is resisted against the bottom surface of the plane of described support.When extracting electromagnetic relay, described terminal can be subject to larger withdrawal force, because the first side of the lower end of described first Plug Division is vacant state, easily make described first Plug Division and connecting portion deform when extracting, and then damage described electromagnetic relay, therefore, the intensity that described first rib can strengthen described first Plug Division and connecting portion is set, thus the larger withdrawal force that can bear, prevent described first Plug Division and connecting portion from deforming.
More specifically, described first rib to extend and perpendicular to the side of described first Plug Division along the plane of described connecting portion.Now, described first rib is positioned at immediately below the first side of the lower end of described first Plug Division, effectively makes up because described first side is unsettled and makes the defect that the pull-out strength of the first Plug Division declines.
Particularly, the opposite side of described connecting portion extends the second rib, and described second rib is resisted against the bottom surface of the plane of described support.The intensity that described second rib effectively strengthens described connecting portion is set, strengthens the holding capacity of described connecting portion further.
More specifically, described second rib bearing of trend level and be parallel to the side of described first Plug Division.
Particularly, the plane of described support is provided with slot, and described connecting portion to be plugged in described slot and to be resisted against the bottom surface of the plane of described support.Described slot can carry out spacing to described terminal, is conducive to the rapid-assembling of terminal.
