Abstract
The utility model discloses a kind of earth clip, comprise bracing frame, clamping part and screw rod, support frame as described above has the first screwed hole.The beneficial effects of the utility model are: earth clip is not easy folding to damage, bad connection, adds the area that is effectively energized simultaneously, solves electric power by the requirement of regulation to grounding technology, avoid accident and personnel's injury that wrong ground connection order causes.
Description
Technical field
The utility model relates to the temporary grounding folder of high and low pressure electric loop.
Background technology
At present, be used in confession, send out, in distribution system, the earth clip of high voltage short circuit earth connection is that the temporary grounding folder adopting metal to make coordinates copper lug to realize, its main implementation has a through hole at the arch section of U-shaped earth clip, concave part on copper lug also has a through hole, then by the through hole on screw bolt passes copper lug and the through hole on U-shaped earth clip, by copper lug and the locking of U-shaped earth clip, but there are following problems in this annexation: because exposed lead-in wire is outside subject to wind-force or manually-operated impact, inevitably drive about copper lug and swing up and down, this can easily cause on the one hand, and copper lug concave part is folding to be damaged, on the other hand as operative, at equipment, when circuit is sent a telegram here suddenly, if equipment, circuit is in short-circuit condition, because tie point loosens, contact resistance increases, the big current that can not cause sending a telegram here suddenly rapidly introduces the earth, then can cause the severe safety consequence of device damage and casualties.
Utility model content
The purpose of this utility model is to provide and is a kind ofly connected firm earth clip with copper lug.The utility model adopts following technical scheme to realize:
A kind of earth clip, comprises bracing frame, clamping part and screw rod, support frame as described above has the first screwed hole.
Copper lug after improvement is connected by thread helix with earth clip, even if the external force of being subject to (wind-force) or manually-operated impact, also be closely interlock between copper lug and earth clip, avoid the situation that loosening appears in part that copper lug is connected with earth clip, thus when even if equipment, circuit are sent a telegram here suddenly, also rapidly incoming call can all be introduced the earth, guarantee equipment and personal safety, in addition, the installed part of copper lug is arranged to cylindrical, shape is the same with aluminium hydraulic pressed connecting pipe, even if be subject to affecting installed part and also can not fractureing in earth clip of external force.
As further improvement of the utility model, the upper end of support frame as described above has anti-back slot.
Anti-back slot and ground connection sequence lock with the use of, ground connection sequence lock is provided with the lock hook matched with anti-back slot, ground connection sequence lock is once lock, lock hook just embeds in the anti-back slot on earth clip, ground connection sequence lock cannot be opened when there is no key, thus also just earth clip cannot be removed, doing so avoids user and first remove when repair apparatus once circuit is sent a telegram here suddenly when earth clip operates again, due to high-tension electricity cannot introduce in time the earth and cause user to get an electric shock danger.
As further improvement of the utility model, described clamping part is provided with pressure switch.
Groove built with pressure switch, when clamping part and bracing frame clamping time, pressure switch conducting.
Further improving as of the present utility model, in described clamping part, being provided with the electronic box for installing battery.
In electronic box, battery is installed.
Further improve as of the present utility model, described clamping part is provided with optical inductor.
Optical inductor can respond to the change of light, and controls conducting and the disconnection of thyristor by the change of light.
Further improve as of the present utility model, described clamping part is provided with photoflash lamp.
On daytime, phototriode is owing to being rendered as low resistance by strong illumination, and thyristor turns off because of triggerless electric current, photoflash lamp does not work, night, and phototriode resistance is maximum, turn on thyristors, photoflash lamp is lighted, and finds earth clip fast when convenient for maintaining personnel keep in repair.
The part that the utility model does not explain all adopts prior art.
In sum, the beneficial effects of the utility model are: it is firm that earth clip is connected with copper lug, when equipment is sent a telegram here suddenly, in time the induced voltage of equipment and residual charge can be introduced the earth, guarantee equipment and personal safety.
Accompanying drawing explanation
Fig. 1 is the utility model earth clip and copper lug syndeton schematic diagram.
Fig. 2 is the structural representation of the utility model earth clip.
Fig. 3 is the syndeton schematic diagram of prior art earth clip and copper lug.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.As depicted in figs. 1 and 2, a kind of earth clip of the utility model, comprise bracing frame 2-1, clamping part 2-3 and screw rod 2-9, one end of bracing frame 2-1 has the second screwed hole 2-10 matched with screw rod 2-9, clamping part 2-3 is connected with one end of screw rod 2-9, clamping part 2-3 moves under the drive of screw rod 2-9 in groove, type bracing frame 2-1 has the first screwed hole 2-2.The other end of bracing frame 2-1 has anti-back slot 2-4, and one end of screw rod 2-9 is fixedly connected with clamping part 2-3, the other end attended operation handle 3 of screw rod 2-9.Clamping part 2-3 is hollow structure, and its inside is provided with electronic box 2-6, and outside is respectively equipped with pressure switch 2-5, optical inductor 2-7 and photoflash lamp 2-8.
As shown in Figure 3, when be subject to wind-force or manually-operated affect time, the swing of lead-in wire must drive copper lug left-right rotation on earth clip, thus cause the tie point of copper lug and earth clip to loosen, contact resistance increases, when equipment is sent a telegram here suddenly, because induced voltage and residual charge can not introduce the earth in time, user must be caused to get an electric shock.
