Abstract
The purpose of the invention is to provide a magnetic grounding clamp that is reliable in grounding connection, convenient to operate and is unlikely to drop, and a portable low-voltage protective grounding wire. The magnetic force of a magnet 8 penetrates through a planar alligator clip 9, so that the alligator clip 9 is firmly adsorbed on a grounding bus of grounding strip iron so as to ensure good grounding, and an insulating handle 3 fully discharges equipment which is confirmed to be non-electrified after electricity verification so as to ensure the personal safety of constructors.
Description
Technical field
The present invention relates to power engineering field, more particularly to a kind of magnetic force earth clip and Portable low-pressure protective grounding
Line.
Background technology
With the increase of user's generating equipment and electrical equipment, the supply network of system of powering becomes increasingly complex, makees having a power failure
The source of falling power transmission is also easy to produce during industry, there is huge hidden danger to personal safety and equipment safety, thus worked on electrical equipment
It is the important technique measure for ensureing workmen using interim protective grounding line, therefore safety code specifies that electrical maintenance works
Personnel must carry with protective grounding line；Existing frequently-used Portable low-pressure protective grounding line is mostly wire using centre,
Each two ends of wire connect a crocodile clip, a kind of this Portable low-pressure protective grounding line, the characteristics of because of crocodile clip, in copper braiding
Ground connection is good and firm when using on line with ground, is being possible to powered connection bolt, framework, device housings, counterpoise grounding
When using on the earth bus of the ferrous materials such as iron, his shortcoming is just displayed, due to crocodile clip and grounding connection position
Only the crown of crocodile clip can be touched, and not only easily be come off, and contact area greatly advises standard less than safety code
Requirement, once misdelivery electrification occurs does not have protective effect, the person of equipment and workmen and life security can be made
Into greatly injury.
The content of the invention
The invention aims to provide a kind of grounding connection reliability, easy to operate and difficult for drop-off magnetic force connects
Ground folder and Portable low-pressure protective grounding line.
Magnetic force earth clip of the present invention and Portable low-pressure protective grounding line are achieved through the following technical solutions：
Magnetic force earth clip and Portable low-pressure protective grounding line include：Hook 1, compression pawl 2, insulated handle 3, energizing spring 4, spiral shell
Bolt 5, earth lead 6, crocodile clip 7, permanent magnetic iron 8, crocodile clip back 9；Characterized in that, having compression pawl 2, insulation hand on hook 1
Handle 3, energizing spring 4, the bolt 5 of connection earth lead 6, the other end of earth lead 6 is connected on crocodile clip 7.
Magnetic force earth clip of the present invention and Portable low-pressure protective grounding line are using the hook 1 for having insulated handle 3 as equipment
End connection member, it is ensured that the personal safety of operating personnel, has energizing spring 4 to provide the compression pawl 2 and the cooperation hook of hook 1 of strength
Hanging over needs the position of ground connection, contacts close and firm；Earth bus end fixedly mounts the crocodile clip 7 of permanent magnetic iron 8 using having,
When using on copper braid over braid ground wire, copper braid over braid is clamped with crocodile clip 7, the crown for making crocodile clip snaps in copper braid over braid；Setting
When using on the earth bus of ferrous material such as standby framework, device housings, counterpoise grounding iron, the crocodile clip back 9 of plane is placed on into table
The good ground connection position of face cleaning, electric conductivity, because the folder chamber built-in type fixed installation permanent magnetic iron 8 of crocodile clip 7, magnet
8 magnetic force makes crocodile clip back 9 tightly adsorb in the equipment frame of irony, device housings, connect through the crocodile clip back 9 of plane
On the earth bus such as area iron.
Furtherly the handgrip part of insulated handle 3 has and needs what the equipment electric pressure for installing protective grounding line was consistent
Insulating barrier, other positions beyond insulating barrier are all manufactured using metal.
Furtherly, compress pawl 2 be flexibly connected with hook 1 near one end of bolt 5.
Furtherly, in the hook and slot of hook 1, another stress point is compressing pawl 2 to a stress point of energizing spring 4
On.
Furtherly, bolt 5 must be connected firmly with earth lead 6, well conducting.
Furtherly, the other end of earth lead 6 is connected in the line ball draw-in groove on crocodile clip 7.
Furtherly, the folder chamber built-in type fixed installation permanent magnetic iron 8 of crocodile clip 7.
Furtherly, crocodile clip 7 has the crocodile clip back 9 of plane.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment the present invention is further detailed explanation：
Fig. 1 is magnetic force earth clip and Portable low-pressure protective grounding cable architecture schematic diagram.
Specific embodiment
Embodiment 1 first stops equipment when using referring to the magnetic force earth clip and Portable low-pressure protective grounding line of Fig. 1
Electricity, firmly pinches the handle of lower crocodile clip 7, and the jaws for making crocodile clip 7 is opened, and clamps copper braid over braid earth bus with crocodile clip 7, really
Protect ground connection well, after then hand-held insulated handle 3 pairs confirms that the equipment without electricity is substantially discharged after electrical verification, 1 will be linked up with
Being hooked in needs the position of ground connection, while compress pawl 2 position for needing ground connection is fastened in hook 1 under the effect of energizing spring 4；
When removing Portable low-pressure protective grounding line, push away before hand-held insulated handle 3, make hook 1 and compress the position that pawl 2 departs from ground connection, use
Power pinches the handle of lower crocodile clip 7, and the jaws for making crocodile clip 7 opens disengaging copper braid over braid earth bus.
Embodiment 2 first has a power failure equipment when using referring to the Portable low-pressure protective grounding line of Fig. 1, by crocodile clip 7
Just to the plane of counterpoise grounding iron cleaning, the magnetic force of magnet 8 makes crocodile clip to the plane of crocodile clip back 9 through the crocodile clip back 9 of plane
The back of the body 9 tightly adsorbs on the earth bus of counterpoise grounding iron, it is ensured that ground connection is good, and then hand-held insulated handle 3 pairs is through electrical verification
After confirming that the equipment without electricity is substantially discharged afterwards, hook 1 is hooked in needs the position of ground connection, while compressing pawl 2 in reinforcing bullet
Spring 4 is fastened on the position for needing ground connection in hook 1 under acting on；When removing Portable low-pressure protective grounding line, hand-held insulation hand
Push away before handle 3, make hook 1 and compress the position that pawl 2 departs from ground connection；Crocodile clip 7 is pinched with hand, firmly makes crocodile clip 7 depart from counterpoise grounding iron
Earth bus.
The preferred embodiment of invention is the foregoing is only, the present invention is not limited to, for the technology of this area
