The relatively independent setting of described corresponding two electrode armature does not link to each other mutually, is arranged with the armature return spring on the armature bracket.
On the described switch case, under the wrench opening, counter electrode is provided with the positioning of electrode bar.
Described spanner can be set in the switch case, is provided with the push-button reset spring between spanner and the housing, and button holds on spanner.
Described electrode can be elastic material.
Can learn that according to above-mentioned structure the utility model operation is easy to implement, the reliability height, low cost of manufacture, ON Action is only finished in the manual control of its button, can not finish and cut off action, can guarantee that circuit is not cut off by external force.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of preferred embodiment structural representation of the present utility model;
View when Fig. 3 is the adhesive of a kind of preferred embodiment of the present utility model contact.
Fig. 2 is another preferred embodiment structural representation of the present utility model.
Referring to Fig. 1, the self-supporting switch that a kind of release of the utility model is not subjected to external action, it is by switch case 1, manual control part, release magnet mechanism, switch electrode and corresponding lead-in wire are formed.Wherein manually control part be one can about the spanner 2 pulled, spanner 2 can be by pulling on the housing 1 that rotating shaft 3 is hinged on switch.Spanner 2 bottoms are provided with an opening 4, be oppositely arranged in the corresponding opening 4 electrode 8,8 ', on the electrode rotating shaft 6,6 of electrode 8,8 ' middle and upper part ' hinged switch case 1, electrode 8,8 ' upper end be provided with contact 5,5 ', contact 5,5 ' opposite face can be inclined-plane or the curved surface that matches, two electrodes 8,8 ' between be equipped with spring 13, spring 13 is connected with two electrodes 8,8 ' insulation.Electrode 8,8 ' by flexible conductor 11,11 ' with the connection of corresponding lead-in wire, go between and be connected to outside the housing electrode 8,8 ' itself can be elastic material again.On the switch case 1, spanner 2 openings 4 times, counter electrode 8,8 ' be provided with positioning of electrode bar 7,7 '.Corresponding each electrode 8,8 ' end be provided with respectively the armature projection 9,9 that fixes electrode 8,8 ' location ', corresponding two electrode armature 9,9 ' relatively independent settings, continuous mutually, be arranged with armature return spring 10 on the armature bracket 14.Release magnet mechanism 12 is established in armature 9,9 ' bottom.
During use, the left and right spanner 2 of pulling, respectively with electrode 8,8 ' pull to position as shown in Figure 2 because the armature projection 9,9 of electrode 8,8 ' bottom ' fixation, and with electrode 8,8 ' location.Because electrode 8,8 ' contact 5,5 ' contact-making surface be inclined-plane or the curved surface that matches, thereby increased the contact area of contact, therefore according to the structure that the utility model disclosed, the capacity of switch can be bigger, and its volume is less, can satisfy various actual needs better.And because electrode 8,8 ' material itself also can be elastomeric material, so the contact of its contact is more abundant, reliably.If when at this moment having the external force desire to cut off this switch, in any case pull spanner 2, external force can't electrode 8,8 ' separation, electrode 8,8 ' the position by the projection 9,9 of armature ' fixing, its contact 5,5 ' always is in self-sustaining attracting state, and can't open this switch from the outside.When cutting off, electromagnet 12 downward adhesive armatures, the armature projection 9,9 of fixed electrode 8,8 ' end ' release electrode 8,8 ', electrode 8,8 ' the be subjected to effect of its back-moving spring 13, rapid separation, return, therefore no matter how external force acts on the spanner, or makes spanner be in what position, all do not influence the cut-out of this device, can only realize by inner circuit control so cut-out of the present utility model discharges.After electromagnet 12 dead electricity, armature be subjected on the armature bracket 14 sheathed spring 10 effects, return moves up.Whole device is in initial condition again.
Referring to Fig. 3, be another kind of preferred embodiment of the present utility model, its spanner 2 can be set in the switch case 1, is provided with push-button reset spring 16 between spanner 2 and the housing 1, and button 15 holds on spanner 2.Because the effect of spring 16, spanner 2 is in the state of inclination, at this moment electrode 8 ' initially promptly be in by armature projection 9 ' fixing position, after pressing button 15, spanner 2 turns left, and electrode 8 contacts are promoted inwardly to rotate, electrode 8 ends are fixing by armature projection 9, two contacts 5,5 ' be in contact with one another, adhesive.In any case at this moment press the button 15 again, can not be from the outside with this switch opens, the total hold mode in its contact 5,5 ' be in.The same example of all the other course of action is described.
Location-plate 7,7 ' effect be to prevent that electrode mistake from going out the opening 4 of spanner 2, and break away from the connection control of spanner 2.
In addition, two electrodes 8,8 of the present utility model ' and housing 1 between be provided with spring 17,17 ', spring 17,17 ' respectively is connected with two electrodes 8,8 ' insulation, as shown in Figure 3.Its effect is equal to the effect of spring shown in Fig. 1,2 fully.
Moreover electrode of the present utility model can be a group or more, when electrode is many groups, and the break-make of this device may command multi-path line.
