As Figure 1-4, anti-electricity-theft earthing clamp in the utility model preferred embodiment comprises penetrating cable clamp 1 and ground loop, ground loop comprises two insulating segments 2 and a conductive segment 3, one end of two insulating segments 2 is connected with the two ends of conductive segment 3 respectively, the two ends of penetrating cable clamp 1 are connected with the other end of two insulating segments 2 respectively, conductive segment 3 is conductive metallic aluminium, insulating segment 2 comprises metallic aluminium and is wrapped in the insulating case outside metallic aluminium, penetrating cable clamp 1 is provided with wire puncture crimping mouth 11, earthing clamp is articulated on low-voltage line by wire puncture crimping mouth 11 to make conductive segment 3 be energized.
Conductive segment 3 top cover in the utility model preferred embodiment has a pair insulating cover 4, insulating cover 4 comprises rotatable lamella 42 and fin 41, rotatable lamella 42 and fin 41 angle are connected to form L-type, the two ends of rotatable lamella 42 embed between insulating case and metallic aluminium to prevent insulating cover 4 from coming off from conductive segment 3, two fins 41 are positioned at the both sides of conductive segment 3, two rotatable lamellas 42 offset away from the side 421 of fin 41, after installation, fin 41 drives rotatable lamella 42 to rotate with opening and closing two insulating covers 4 along the surface of conductive segment 3 under the effect of external force, when the side 421 of two rotatable lamellas 42 offsets, described two insulating covers 4 close, the top of conductive segment 3 is isolated from the outside, when two rotatable lamellas 42 side 421 mutually away from time, described two insulating covers 4 are opened, the top of conductive segment 3 communicates with the external world.
Can automatically close in order to two insulating covers 4 can be made, resetting device 5 is also provided with between two insulating covers 4, as shown in Figure 3, resetting device 5 in this preferred embodiment is spring preferably, spring is arranged between the end of two rotatable lamellas 42, and spring is positioned at insulating case to extend the useful life of spring.When two insulating covers 4 are in open mode, when after being applied to the disappearance of the external force on fin 41, fin 41 drives rotatable lamella 42 upwards to rotate two insulating covers 4 are closed under the pulling force of spring, when practical application, technical staff can select stiffness factor and the stretching limit of spring according to actual needs.
In other embodiments of the present utility model, for the ease of the maintenance of later stage to resetting device, resetting device can be opposite polarity two magnet, two magnet is separately positioned on the side that two rotatable lamellas offset, after being applied to the disappearance of the external force on fin, rotatable lamella upwards rotates two insulating covers are closed under magnetic attraction.
Elastic insulated 5 is also connected with between outside two insulating covers 4, insulating trip 5 is connected between the outside of two rotatable lamellas 42, when two insulating covers 4 close, insulating trip 5 is wrapped in the outside of conductive segment 3, to prevent conductive segment 3 from leaking electricity, also avoid conductive segment 3 to be oxidized under extraneous environmental impact simultaneously, extend the useful life of ground loop, when two insulating covers 4 are opened, insulating trip 5 is compressed to make the surface of conductive segment 3 to communicate with the external world under the extruding of rotatable lamella 42.
When daily operation, two insulating covers 4 are in closure state, conductive segment 3 is wrapped up by insulating cover 4 and insulating trip 5, when electricity filching person hooks conductive segment 3 by stealing hook, because fin 41 is arranged near vertical direction, stealing hook is ring-type, and therefore stealing hook does not open two insulating covers 4 by fin 41, make the top of stealing hook and conductive segment 3 cannot form through loop, evade the possibility of stealing.When staff needs to carry out inspection and maintenance to circuit, in order to ensure personal safety during work, need earthing clamp to carry out ground connection by earthing tool, in prior art, earthing tool generally adopts clamp for ground wire, clamp for ground wire end is provided with hook 7, the other end is provided with the wire be connected with the earth, as shown in Figure 5, links up with 7 ends and is provided with the flexible conjunction groove 71 in X-type, open in the structure prior art of remainder, illustrate no longer one by one at this.
As shown in a to f in Fig. 6, in use, conjunction groove 71 is articulated on conductive segment 3 and also pulls hook 7 downwards, close groove 71 and be applied to the downward frictional force of fin 41, make fin 41 drive rotatable lamella 42 to rotate and open two insulating covers 4 gradually, conductive segment 3 is then extruded the top entering and close groove 71 gradually, when conductive segment 3 is positioned at the top of closing groove 71, two insulating covers 4 are opened completely, now conductive segment 3 contacts with hook 7 and is energized, be grounded, in order to make earthing effect better, when two insulating covers 4 are opened completely, the exposed area in the external world of conductive segment 3 is greater than 1/2 of its gross area, namely the arc length of rotatable lamella 42 is less than 1/4 of conductive segment 3 circumference, conductive segment 3 can be made to realize three with the both sides of hook 7 with top with this to contact, increase conductive effect.
As shown in Figure 4, fin 41 slide downward is made to open two insulating covers 4 when mounting to enable hook 7 swimmingly, be provided with arc-shaped protrusions 411 at the edge of fin 41, the sliding friction that arc-shaped protrusions 411 can reduce fin 41 and close between groove 71, extend the useful life of insulating cover 4.
After the end of job, hook 7 is taken out from earthing clamp, now above-mentioned steps is reversed by two insulating covers 4 of earthing clamp under the effect of resetting device 5, until conductive segment 3 deviates from hook 7, recover the state of closed insulation, whole step is action intervention without the need to people, uses convenient, and to hang mode identical with the earthing clamp of routine.Anti-electricity-theft earthing clamp in the utility model preferred embodiment is the improvement carried out on the basis of conventional earthing clamp, there is the simple feature of processing, earthing tool matching used with it is also without the need to changing simultaneously, in singlehanded electrical verification, hang, remove, operating speed, flow process all do not have difference with conventional earthing clamp, and construction, O&M convenience is very high.
Earthing tool only has the spendable special tool(s) of the ability of work about electric power personnel, and country carries out strict management and control to it, and therefore general personnel are can not be obtainable, can electricity theft prevention personnel adopt this instrument to carry out stealing.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto, is familiar with this those skilled in the art and should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in embodiment above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
