Abstract
The utility model discloses an isolator, comprising a housing (1). A reed (2) is fixed on the housing (1), a knife switch (3) is hinged to the housing (1), and an inserted sheet (4) for inserted with the reed (2) is fixed on a free end of the knife switch (3). The knife switch (3) is provided with an apparatus for performing deadlock for the open knife switch (3). The isolator can prevent a circuit which needs to be cut off from conducting because of sudden status.
Description
Technical field
The utility model relates to the electric elements fields, is specifically a kind of isolator.
Background technology
Isolator is the electric elements of control circuit break-make, and it comprises housing, is fixed with reed on housing, also be hinged with plug-in strip on housing, the free end of plug-in strip namely non-hinged end is fixed with for the inserted sheet of pegging graft with reed, and reed and inserted sheet are electrically connected to from different electric wire respectively, the lower plug-in strip of pressing, make plug-in strip closed, the inserted sheet that is plug-in strip inserts in reed, circuit turn-on, on pull out plug-in strip, making plug-in strip open is inserted sheet and the reed disengaging of plug-in strip, and circuit disconnects.After isolator disconnects circuit, plug-in strip may because Action of Gravity Field or external force collision even because the people for misoperation reinserts in reed, cause should the dead circuit conducting, thereby cause security incident.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of can prevent unexpected situation cause should the dead circuit conducting isolator.
Technical solution of the present utility model is, a kind of isolator is provided, and it comprises shell, be fixed with reed on shell, be hinged with plug-in strip on shell, the free end of plug-in strip is fixed with for the inserted sheet of pegging graft with reed, and plug-in strip is provided with the device that the plug-in strip of opening is locked.
Adopt the isolator of above structure compared with prior art, have the following advantages:
Because plug-in strip is provided with the device that the plug-in strip of opening is locked, like this, when plug-in strip open mode circuit disconnects, can plug-in strip is locked, therefore the situation that avoid that Action of Gravity Field, accident collision etc. make that plug-in strip is closed, inserted sheet reinserts the circuit turn-on that reed causes, also can effectively avoid the people is misoperation.
As improvement, be fixed with hook on shell, the free end of plug-in strip is hinged with under the plug-in strip open mode link with the hook hooking, and like this, under the plug-in strip open mode, the user just can be effectively locked with plug-in strip with link and hook hooking, and operation is simple and reliable.
As improving again, be fixed with projection on shell, the free end of plug-in strip is fixed with rope, and the free end of rope is provided with the collar that is used for the projection fit under the plug-in strip open mode, like this, under the plug-in strip open mode, the user with the collar with the projection fit, the rope that is connected with the collar can be strained plug-in strip, prevents from that plug-in strip from falling to cause inserted sheet to be pegged graft in reed, namely effectively that plug-in strip is locked, operation is simple and reliable.

Fig. 2 is the structural representation of the another kind of embodiment of the utility model isolator.
Shown in figure 1, shell, 2, reed, 3, plug-in strip, 4, inserted sheet, 5, hook, 6, link, 7, projection, 8, rope, 9, the collar.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of embodiment of the utility model isolator, it comprises shell 1.Be fixed with reed 2 on shell 1, be hinged with plug-in strip 3 on shell 1, the free end of plug-in strip 3 is fixed with for the inserted sheet 4 of pegging graft with reed 2.Plug-in strip 3 is provided with the locked device of plug-in strip 3 that will open, its concrete structure is, be fixed with hook 5 on shell 1, the free end of plug-in strip 3 is hinged with under plug-in strip 3 open modes the link 6 with hook 5 hookings, in particular, when the aperture of plug-in strip 3 is maximum namely the inserted sheet 4 of plug-in strip 3 from reed 2 farthest the time, link 6 and hook 5 hookings.
As shown in Figure 2, the another kind of embodiment of the utility model isolator, this embodiment and last embodiment difference are, the concrete structure that plug-in strip 3 is provided with the locked device of the plug-in strip 3 that will open is: be fixed with projection 7 on shell 1, the free end of plug-in strip 3 is fixed with rope 8, the free end of rope 8 is provided with the collar 9 that is used for projection 7 fits under plug-in strip 3 open modes, in particular, namely the inserted sheet 4 of plug-in strip 3 is from reed 2 farthest the time when the aperture of plug-in strip 3 is maximum, and the collar 9 is linked on projection 7.
