Need to discharge and hang temporary ground wire when indoor electric equipment maintenance, test.To make ground line have good ground connection Condition avoids being grounded arbitrarily unrest and connects, therefore temporary grounding terminal is arranged.
Usual temporary grounding terminal way is that a band steel is found around equipment, is drilled on top, with a bolt crimping Ground line.This kind of ground terminal is not eye-catching enough, if not note that easily accidentally touching off ground line causes safety accident.When hanging ground line Bolt need to be turned, it is inconvenient for operation.Band steel be exposed to it is outer also unsightly.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems, proposing temporary grounding terminal box in a kind of Novel wall.
The technical scheme is that
Temporary grounding terminal box, the ground terminal case are embedded in wall one kind within the walls, and a bronze medal is arranged in ground terminal case It arranges, several screw holes is opened up on copper bar, aforementioned copper bar is equipped with access area and test section;
In access area, the lead-out wire of indoor ground connection looped network is crimped to aforementioned copper bar by two copper stranded conductors respectively, so that room Interior ground connection looped network is connected to copper bar;
In test section, WING NUTS is inserted into aforementioned screw hole as ground terminal and screws WING NUTS by screw rod and side's pad It can clamping ground line.
Further, insulator is installed on wall, is supported between copper bar and wall by insulator.
Further, the region on copper bar with button grounding clamp mounts button grounding clamp as ground terminal.
Further, ground terminal case uses stainless steel cabinet.
Further, binder, pointing flexibility sealing layer are coated between ground terminal case and wall.
Further, ground terminal case is equipped with chamber door, with 4mm2Annealed copper wire is connected to cabinet and indicates ground connection symbol mark Will;Ground connection symbol specification is 60mm × 60mm.
Further, lockset is set on chamber door.
Further, the specification of ground terminal case is 210mm × 300mm × 120mm.
Further, the specification of copper bar is 25mm × 4mm, long 280mm.
Beneficial effects of the present invention:
The one small case of stainless steel material temporary grounding terminal of insertion is arranged in the present invention on the wall, and pointing is flexible between cabinet and wall Sealing material.Chamber door is connected to cabinet with annealed copper wire, and ground connection symbol is indicated after mopping.Lockset is set on chamber door, is usually located In blocking, prevent personnel from arbitrarily opening.
One copper bar is set in case of the invention, and indoor ground connection looped network draws two copper stranded conductors and is crimped to copper bar respectively, guarantees to connect The reliability on ground.Closure is carried out using fire-proof mud between copper stranded conductor and cabinet.It is supported between copper bar and wall by insulator, while The region for hanging button grounding clamp is reserved on copper bar.Ground terminal on copper bar fastens ground connection using WING NUTS and screw rod Line, it is convenient and efficient.
The configuration of the present invention is simple is beautiful, and has very strong fire-proof waterproof anticorrosive ability.Reliably grounded connection is played to make With WING NUTS need to only be turned by hanging when fastening is grounded, and be operated very convenient.
Other features and advantages of the present invention will then part of the detailed description can be specified.
Detailed description of the invention
