Description
Technical field
The utility model relates to earth connection, is specially a kind of earth connection with blocking function.
Background technology
At present, do not have fixing corresponding relation between the earth connection of use and electric equipment, although this method uses flexibly, there are the following problems for this method: one, easily go to the wrong way place during operation, causes installing by mistake, removes earth connection by mistake; Two, may not according to " electrical safe working order " regulation order, namely first to connect earth terminal during earth connection, after connect conductor end; Order during dismounting earth connection in contrast.Dress, dismounting ground wire; Three, may occur that the phenomenon of item is leaked in earth connection operation; Four, when tightening conductor end wire clamp, wire clamp follows hook stick to rotate, and is difficult to clamping conductor.
Utility model content
The technical problem that the utility model solves is to provide a kind of earth connection with blocking function, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of earth connection with blocking function, comprise for fixing lock collar, the fixing clamper of dead earth line, back-moving spring and insulation hold-down bars, described fixing clamper is " V " type structure or " U " type structure, a movable disk is provided with in described fixing clamper, the side of described fixing clamper is provided with through hole, motion bar in described lock collar is connected with described movable disk by through hole, also be connected by described back-moving spring with the top of movable disk in described lock collar, described insulation hold-down bars is between described movable disk and fixing clamper, described insulation hold-down bars is provided with the perforation of passing for earth connection, fixing lock is also provided with between described lock collar and fixing clamper, the one side that described fixing clamper is relative with movable disk is equipped with arc groove.
In the utility model, the side that described lock collar is provided with some lockholes and lock collar is provided with limiting locking plate, lock collar can be fixed by limiting locking plate.
In the utility model, the one side that described fixing clamper is relative with movable disk is equipped with arc groove, and the situation of squeeze and destroy insulation hold-down bars can not occur through arc groove insulation hold-down bars.
The beneficial effects of the utility model: effectively prevent the phenomenon connecing, occur when tearing ground wire open operating sequence mistake.In the transformation of the earth connection used at transformer station and circuit, during ground connection, the housing of wire clamp no longer rotates, and is operating as conveniently.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is lock collar generalized section.
In figure: 1-lock collar, 2-fixing clamper, 3-back-moving spring, 4-insulate hold-down bars, 5-movable disk, and 6-bores a hole, the fixing lock of 7-, 8-limiting locking plate, 1.1-lockhole, 2.1-arc groove.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of earth connection with blocking function, comprise lock collar 1, fixing clamper 2, back-moving spring 3 and insulation hold-down bars 4, described fixing clamper 2 is " V " type structure, a movable disk 5 is provided with in described fixing clamper 2, the side of described fixing clamper 2 is provided with through hole, motion bar in described lock collar 1 is connected with described movable disk 5 by through hole, also be connected by described back-moving spring 3 with the top of movable disk 5 in described lock collar 1, described insulation hold-down bars 4 is between described movable disk 5 and fixing clamper 2, described insulation hold-down bars 4 is provided with the perforation 6 of passing for earth connection, fixing lock 7 is also provided with between described lock collar 1 and fixing clamper 2.
In the utility model, described fixing clamper 2 can also be " U " type structure.
In the utility model, described lock collar 1 is provided with some lockholes 1.1.
In the utility model, the one side that described fixing clamper 2 is relative with movable disk 5 is equipped with arc groove 2.1.
In the utility model, the side of described lock collar 1 is provided with limiting locking plate 8.
Execution mode: when not using earth connection, lockhole 1.1 will be fixed by the fixed lever on limiting locking plate 8 by the lock collar 1 of earthing device.Fixing clamper 2 pins described insulation hold-down bars 4.When needing earth connection, open limiting locking plate 8, open lock collar 1, under the effect of back-moving spring 3, movable disk 5 activity is unclamped, and fixing clamper 2 unclamps, insert the insulation hold-down bars 4 adapted to, then tighten lock collar 1 to be fixed by movable disk 5, limiting locking plate 8 locks the lockhole 1.1 in lock collar 1, then the fixing lock 7 of locking, insulation hold-down bars 4 and fixing clamper 2 are locked, and complete earth terminal operation.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
