Description
Affiliated technical field
The utility model relates to a kind of earthing clamp, especially a kind of puncture earthing clamp.
Background technology
At present, when overhead insulation line line outage is overhauled, must articulate the life security that earth connection could guarantee the maintainer.When adopting aerial bare line, earth connection is directly hung on the plain conductor, just the purpose that can be grounded in the past.But after using overhead insulation line instead now, hanging earthing conductor has but become difficulty during interruption maintenance, must manually cut the insulation sheath of insulated electric conductor open, earth connection is hung up again, and operating process is relatively more dangerous like this.
Summary of the invention
In order to address the above problem, the utility model provides a kind of puncture earthing clamp, the hanging earthing conductor on overhead insulation line that this puncture earthing clamp can safe ready, and simple installation, electric property are stable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of puncture earthing clamp, comprise plastic casing, following plastic casing, contactor blade and ground loop, last plastic casing and following plastic casing fasten mutually, and compress by screw bolt and nut, be provided with main line folder mouth and ground loop connector between last plastic casing and the following plastic casing, be connected with ground loop on the ground loop connector, be provided with contactor blade in the main line folder mouth.
The last plastic casing back side is provided with parallels, and the following plastic casing back side is provided with lower padding iron.
Be provided with elastomeric pad between nut and the last parallels.
Described contactor blade is the dentation blade.
The contactor blade quantity of the main line clamp mouth part setting of last plastic casing is 4, and the contactor blade quantity of the main line clamp mouth part setting of following plastic casing is 4.
The contactor blade quantity of the main line clamp mouth part setting of last plastic casing is 3, and the contactor blade quantity of the main line clamp mouth part setting of following plastic casing is 3.
Because this puncture earthing clamp comprises plastic casing, following plastic casing, contactor blade and ground loop, be provided with main line folder mouth and ground loop connector between last plastic casing and the following plastic casing, be connected with ground loop on the ground loop connector, be provided with contactor blade in the main line folder mouth, main line folder mouth can be clipped on the insulated electric conductor, contactor blade thrusts the exterior insulation skin of insulated electric conductor, contact with the lead of insulated electric conductor inside, again ground wire is articulated on the ground loop, can be grounded easily like this, simple installation, electric property are stablized.
Description of drawings
Fig. 1 is the puncture structure chart of earthing clamp of embodiment;
Fig. 2 is the puncture left view of earthing clamp of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of puncture earthing clamp, comprise ambroin shell 4, descend ambroin shell 6, go up big parallels 3, descend big parallels 7, bolt 9, torque nut 1, contactor blade 5 and ground loop 8, relevant position on the upper and lower plastic casing wall respectively is provided with two breach, form main line folder mouth and ground loop connector after the upper and lower plastic casing amalgamation, last plastic casing 4 back sides are provided with big parallels 3, following plastic casing 6 back sides are provided with down big parallels 7, big parallels is further guaranteed the wire clamp connection reliability as the bearing of wire clamp; Be provided with the insulated hollow pillar in the last plastic casing 4, bolt 9 is connected with nut 1 after passing the insulated hollow pillar, described nut 1 is a torque nut, nut 1 and bolt 9 are pressed in respectively on parallels 3 and the lower padding iron 7, ambroin shell 4 and following ambroin shell 6 are compressed, be lined with dish-shaped elastomeric pad 2 between nut 1 and the last parallels 3, this elastomeric pad 2 can compensate because of the lead creep causes the unfavorable conditions such as decline, contact resistance increase of conductor contact pressure in the contactor blade of wire clamp and the lead and take place.The main line clamp mouth part of last plastic casing 4 is provided with four contactor blade 5, and the main line clamp mouth part of following plastic casing 6 also is provided with the contactor blade 5 of four pairings, and contactor blade 5 positions are filled with sufficient insulation grease.Ground loop connector place is connected with ground loop 8, and ground loop 8 is by lead and contactor blade 5 conductings.
During use, ground loop 8 is clipped in the ground loop connector, main line folder mouth is clamped the insulated conductor that needs ground connection, tight a bolt 9, make the right contactor blade of four assembly 5 thrust the insulation sheath of insulated conductor, insulated conductor can pass through contactor blade 5 and ground loop 8 conductings like this, during power construction, earth rod can link directly in the exposed section of ground loop 8, realizes the purpose of lead safety ground, guarantees safety of construction.Insulation grease during puncture around the contactor blade 5 can be filled the space sealing by nature, guarantees insulation effect.The bolt 9 of wire clamp and torque nut 1 constitutes the puncture pressure control device, tightens when reaching the design moment value when bolt 9, and torque nut 1 can fall automatically, can prevent the excessive damage wires of contactor blade puncture pressure when guaranteeing enough puncture pressure again.
Because the puncture earthing clamp need not to peel off the insulating barrier of lead when installing, as long as insulated conductor and ground loop are required to put into the wire clamp tram in accordance with regulations, hand-tight make-up torque nut then, use the even screw-down torque nut of insulating sleeve spanner again, get final product until the torque nut disconnection, so simple installation.In addition, because the torque nut in the puncture earthing clamp can be guaranteed constant puncture pressure, makes earthing clamp and lead reach good electric the contact and damage wires within reason, realizes the purpose of safety ground, and guarantee suspended insulated guide wire normal useful life that electric property is stable.The connection of the suitable different cross section suspended insulated guide wire of puncture earthing clamp, the suitable suspended insulated guide wire of model wire clamp all has three to four specifications, and the scope of application is wider.
The above is a preferred implementation of the present utility model; should be understood that; do not break away from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
