Abstract
The utility model discloses an electromagnet suction-type socket, characterized in that bimetallic strips are connected on a zero line joint and a live wire joint respectively via conducting wires, the bimetallic strips are pressed on a static contact tightly, and two electromagnetic coils are in series connections together, with one end connected with the live line and the other end connected with a normally open contact; the other end of the normally open contact is connected together with the zero line joint to form a loop, and a reactive force spring acts on an armature, so that the armature is contacted with the static contact tightly. By the above arrangement and according to the electromagnet suction-type socket of the utility model, the situation is guaranteed that a contact point does not happen poor contact, and the contact point is not overheated to cause various accidents.
Description
Technical field
The utility model relates to a kind of Novel socket, is a kind of suction type socket that utilizes electromagnet to carry out work specifically.
Background technology
At present, common socket need be used larger power when plug inserts, and through after repeatedly plugging, the shell fragment of socket can cause loose contact because elasticity is bad, causes cisco unity malfunction or overheated having an accident.
Summary of the invention
The purpose of this utility model provides a kind of electromagnetic actuation formula socket good, that coefficient of safety is high, the life-span is long that contacts.
To achieve these goals, the utility model is connected with the live wire joint respectively at the zero line joint and is connected bimetal leaf by wire, bimetal leaf is pressed on the static contact, two solenoids are cascaded, one end connects the live wire joint, the other end connects normally open contact, the other end of normally open contact and zero line joint link together, consist of a loop, solenoid is wrapped on the iron core, reaction force spring and iron core are fixed together, and the reaction force spring action makes armature and static contact close contact on armature.
By above setting, during latch plug the utility model, can by the adhesive of armature, with the latch plug, guarantee that contact point can not come in contact bad situation.If cause loose contact because of a variety of causes, contact point adstante febre, the utility model also have the bimetal leaf control device will automatic shutoff circuit, can not cause contact point overheated and various accidents occur.
Description of drawings
Now the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 static contact, 2, bimetal leaf, 3, armature, 4, the reaction force spring, 5, iron core, 6, solenoid, 7, normally open contact, 8, the zero line joint, 9, the live wire joint, 10, earth connection point.
Embodiment
As shown in Figure 1, the utility model zero line joint 8 with connect bimetal leaf 2 by wire respectively on the live wire joint is connected, bimetal leaf 2 is pressed on the static contact 1, two solenoids 6 are cascaded, one end connects live wire joint 9, the other end connects normally open contact 7, the other end of normally open contact 7 and zero line joint 8 link together, consist of a loop, solenoid 6 is wrapped on the iron core 5, reaction force spring 4 is fixed together with iron core 5, and reaction force spring 4 acts on the armature 3, makes armature 3 and static contact 1 close contact.By above setting, when the utility model uses, press normally open contact 7, solenoid 6 gets electric, makes iron core 5 produce magnetic attracting armature 3, at this moment plug can be inserted socket smoothly, then normally open contact 7 is unclamped, armature 3 resets, and plug and static contact 1 is pressed together, thereby guaranteed the good contact of plug and socket.Resistance was very little when the utility model inserted at plug, improved the ease for use of socket, insertion process can not cause static contact 1 that deformation and wearing and tearing occur, the life-span of socket is prolonged greatly, owing to make plug and socket contact good by extruding, guaranteed the fail safe of socket, if because misoperation contact point when overheated, bimetal leaf 2 of the present utility model will automatic shutoff circuit, has guaranteed safety utilization of electric power.
