【Embodiment】
The technical scheme of the embodiment of the present invention is explained and illustrated with reference to the accompanying drawing of the embodiment of the present invention, but under
It is only the preferred embodiments of the present invention to state embodiment, and not all.Based on the embodiment in embodiment, those skilled in the art
Other embodiment is obtained on the premise of creative work is not made, belongs to protection scope of the present invention.
As Figure 1-4, the anti-electricity-theft earthing clamp in the preferred embodiment of the present invention includes penetrating cable clamp 1 and ground connection
Ring, ground loop include two insulating segments 2 and a conductive segment 3, and the both ends of one end of two insulating segments 2 respectively with conductive segment 3 connect
Connect, the other end of the both ends of penetrating cable clamp 1 respectively with two insulating segments 2 is connected, and conductive segment 3 is conductive metallic aluminium, insulation
Section 2 includes metallic aluminium and the insulation sleeve being wrapped on the outside of metallic aluminium, and wire is provided with penetrating cable clamp 1 and punctures crimping mouth 11, is connect
Ground clamp punctures crimping mouth 11 by wire and is articulated on low-voltage line so that conductive segment 3 is powered.
The top of conductive segment 3 in the preferred embodiment of the present invention is cased with a pair of insulating boots 4, and insulating boot 4 includes the He of rotatable lamella 42
Fin 41, rotatable lamella 42 are connected to form L-type with the angle of fin 41, between the both ends of rotatable lamella 42 insertion insulation sleeve and metallic aluminium with
Prevent insulating boot 4 from being come off from conductive segment 3, two fins 41 are located at the both sides of conductive segment 3, and two rotatable lamellas 42 are away from fin 41
Side 421 offset, after installation, fin 41 drives surface of the rotatable lamella 42 along conductive segment 3 to do week in the presence of external force
To rotating to be opened and closed two insulating boots 4, when the side 421 of two rotatable lamellas 42 offsets, described two insulating boots 4 close, and lead
The top of electric section 3 is isolated from the outside, and when the side 421 of two rotatable lamellas 42 is located remotely from each other, described two insulating boots 4 are opened,
The top of conductive segment 3 communicates with the external world.
In order to make two insulating boots 4 to close automatically, resetting-mechanism 5 is additionally provided between two insulating boots 4, is such as schemed
Shown in 3, the 5 preferred spring of resetting-mechanism in this preferred embodiment, spring is arranged between the end of two rotatable lamellas 42, and bullet
Spring is located in insulation sleeve to extend the service life of spring.When two insulating boots 4 are in open mode, when being applied to fin 41
On external force disappear after, fin 41 is rotated up in the pulling force lower band turn moving plate 42 of spring so that two insulating boots 4 close,
During practical application, technical staff can be according to the stiffness factor and stretching limit for being actually needed selection spring.
In other embodiments of the invention, for the ease of maintenance of the later stage to resetting-mechanism, resetting-mechanism can be polarity
Two opposite magnet, two magnet are separately positioned on the side that two rotatable lamellas offset, when the external force being applied on fin
After disappearance, rotatable lamella is rotated up under magnetic attraction so that two insulating boot closures.
It is also associated with elastic insulated 5 between the outside of two insulating boots 4, insulating trip 5 is connected to two rotatable lamellas 42
Between outside, when two insulating boots 4 close, insulating trip 5 is wrapped in the outside of conductive segment 3, to prevent conductive segment 3 from leaking electricity, simultaneously
Also avoid conductive segment 3 from being aoxidized under the influence of external environment, extend the service life of ground loop, when two insulating boots 4 are opened
When, insulating trip 5 is compressed under the extruding of rotatable lamella 42 so that the surface of conductive segment 3 communicates with the external world.
In daily operation, two insulating boots 4 are in closure state, and conductive segment 3 is wrapped up by insulating boot 4 and insulating trip 5, when
When electricity filching person hooks conductive segment 3 by stealing hook, due to fin 41 near vertical direction set, stealing hook be ring-type, because
This stealing hook can not open two insulating boots 4 by fin 41 so that the top of stealing hook and conductive segment 3, which can not be formed, to be passed through
Logical loop, has evaded the possibility of stealing.When staff needs to carry out inspection and maintenance to circuit, during in order to ensure work
Personal safety, it is necessary to earthing clamp is grounded by earthing tool, in the prior art, earthing tool is typically using ground connection
Line is linked up with, and clamp for ground wire end is provided with hook 7, and the other end is provided with the wire being connected with the earth, as shown in figure 5,7 ends of hook are set
The flexible conjunction groove 71 in X-type, the structure of remainder is disclosed in the prior art, no longer illustrates one by one herein.
As shown in a to f in Fig. 6, when in use, groove 71 will be closed and be articulated on conductive segment 3 and pull downward on hook 7, close groove
71 are applied to the downward frictional force of fin 41, make fin 41 drive rotatable lamella 42 to rotate down and be gradually opened two insulating boots 4,
And conductive segment 3 is then gradually squeezed into the top for closing groove 71, when conductive segment 3 is positioned at the top for closing groove 71, two insulating boots 4
Open completely, now conductive segment 3 contacts energization with hook 7, is grounded, in order that earthing effect is more preferable, two insulating boots 4 are complete
During full opening, the exposed area in the external world of conductive segment 3 is more than the 1/2 of its gross area, that is, the arc length of rotatable lamella 42 is less than
The 1/4 of the circumference of conductive segment 3, with this conductive segment 3 and the both sides of hook 7 can be made to realize that three faces contact with top, increase conductive effect
Fruit.
As shown in figure 4, in order that hook 7 mounting when can swimmingly make the slide downward of fin 41 open two insulating boots 4,
Arc-shaped protrusions 411 are provided with the edge of fin 41, arc-shaped protrusions 411 can reduce fin 41 and close the sliding friction between groove 71,
Extend the service life of insulating boot 4.
After the end of job, hook 7 is taken out from earthing clamp, now the two of earthing clamp insulating boot 4 is resetting machine
Above-mentioned steps are reversed in the presence of structure 5, until the abjection of conductive segment 3 hook 7, recovers to close the state of insulation, whole step
Suddenly intervene without artificially action, use is more convenient, and it is identical with the earthing clamp of routine to hang mode.It is of the invention preferred real
It is the improvement carried out on the basis of conventional earthing clamp to apply the anti-electricity-theft earthing clamp in example, has processing simple special
Point, while matched earthing tool is without change, in singlehanded electrical verification, hang, remove, operating speed, flow are equal
There is no difference with conventional earthing clamp, construction, O＆M convenience are very high.
Earthing tool is special tool(s) only workable for the ability of work about electric power personnel, and country carries out strict management and control to it,
Therefore general staff be can not be obtainable, can prevent stealing personnel using this instrument carry out stealing.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, and is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to accompanying drawing and interior described in embodiment above
Hold.The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
