Abstract
An unipotential ground connection end box is characterized in that the utility model comprises a box face plate cover (1), an end box (3), a ground connection end plate (2) and a ground connection screw bar (4), wherein the ground connection screw bar (4) goes across a screw hole (6) on the ground connection end plate (2) and is fixed by a bolt, the ground connection end plate (2) is fixed on the end box (3), the main face of the ground connection end plate (2) is equipped with a plurality of screw holes, and the side face of the ground connection end plate (2) is equipped with a plurality of unipotential wires (7). The utility model overcomes the deficits that the spot made ground connection end basically adopts the steel plate welding processing method, which wastes time and power, has low production efficiency and cannot meet the multi-rout one point ground connection. The utility model is mainly used for partial electric potential connection of a house bath room, a hotel bath room, a public bath room, a hospital ward bath room, a hospital anocelia surgery operating room and the like.
Description
Technical field
The utility model relates to a kind of terminal board, and more particularly it is a kind of electrical grounding terminal board.
Background technology
The equipotential bonding technology all clearly is defined as the basic measures of electrical safety in IEC60364-4-41 and China's national standard and Code for design of dwelling houses.Still do not have the local equipotential bonding device of special-purpose standardization in the market, all do not do local equipotential bonding construction in a lot of engineerings, cause potential electrical safety hidden danger virtually by designing requirement.Therefore, bring many inconvenience for design and construction.The earth terminal of field fabrication adopts steel plate welding processing mode substantially, time-consuming, take a lot of work, production efficiency is low and can not satisfy the needs of multichannel one point earth.
Summary of the invention
The purpose of this utility model is to overcome the weak point in the above-mentioned background technology and a kind of electrical grounding terminal board is provided.It meets the specification requirement among the national standard atlas 02D501-2, meets the relevant regulations among GB GB50303-2002, the CECS107-2000 simultaneously, and easy construction, and is safe and reliable, applied range.
The purpose of this utility model reaches by following measure: the electrical grounding terminal board, it is characterized in that it is made up of terminal board panel cover 1, terminal board 3, earth terminal daughter board 2 and grounding screw rod 4, grounding screw rod 4 passes the screw 6 on the earth terminal daughter board 2 and fixes through nut, earth terminal daughter board 2 is fixed on the terminal board 3, the interarea of described earth terminal daughter board 2 is provided with some screws, and the side of earth terminal daughter board 2 is provided with some equipotential wire guides 7.
On the described grounding screw rod 4 special welding connector 5 is arranged.
In technique scheme, the screw on described earth terminal daughter board 2 interareas evenly distributes along the screw 6 that grounding screw rod 4 passes on the earth terminal daughter board 2.
In technique scheme, positive center, described terminal board 3 bottoms has a circular hole 8.
The utility model mainly is used as the usefulness of the local equipotential connection in residence toilet, toilet, hotel, bathhouse, hospital ward toilet, the hospital's thoracic surgery operating room.It has following advantage particularly: when satisfying Modern Decorative, decoration needs attractive in appearance, can reach economical and practical, installation effect easily again, long service life, safety, reliable, corrosion-resistant, and the construction of suitable secondary decoration and installation requirement, satisfied the needs of multichannel one point earth simultaneously.

Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing:
1 is that terminal board panel cover, 2 is that earth terminal daughter board, 3 is that terminal board, 4 grounding screw rods, 5 are that screw, 7 is that equipotential wire guide, 8 is that circular hole, 9 is that the interior main muscle of post, 10 is that post, 11 is that weld, 12 is that brick wall, 13 is service sleeve, circular hole, building bar-mat reinforcement, electrical grounding terminal board for being welded to connect body, 6 among the figure.
From accompanying drawing as can be known: the utility model is made up of terminal board panel cover 1, terminal board 3, earth terminal daughter board 2 and grounding screw rod 4, grounding screw rod 4 passes the big screw 6 on the earth terminal daughter board 2 and fixes through nut, earth terminal daughter board 2 is fixed on the terminal board 3, the interarea of earth terminal daughter board 2 has 8 little screws and 1 big screw, and there are 4 equipotential wire guides 7 its side.(as shown in Figure 2), the number that need to prove equipotential wire guide 7 and screw 6 can come to determine in application as required.
The panel cover 1 of terminal board is selected high-quality engineering plastics compression moulding for use, and is handsome in appearance generous, and with cubicle switch panel conformance to standard, harmony seems when interior decoration.
Earth terminal daughter board 3 adopts the superior alloy steel processing and fabricating to form, the decoration integrated chrome-plated process of anticorrosion is adopted in surface treatment, earth terminal plate structure compactness, after the equipotential bonding lead is introduced in the box, adopt zinc-plated soket head cap screw crimping lead, not only do not hinder lead and crimping is solid and reliable, and can prevent that the layman from operating without authorization.
What connect the earth terminal daughter board is a zinc-plated grounding screw rod 4, and the main reinforcement in screw rod and the building strut (or shear wall) welds together.Work progress is simple and easy to do, and electric connection is closely reliable.
The utility model is embedded concealed installation, in the time of in being installed in post (or shear wall), should be when civil engineering, at first zinc-plated grounding screw rod 4 is embedded in the post (or shear wall) with terminal board 3, should guarantees that the main reinforcement of zinc-plated grounding screw rod 4 and building strut interior (or in shear wall) welds together (as shown in Figure 4).When terminal board was installed on the wall, the main muscle welding in the Ying Zaizhu (or shear wall) was reserved and is drawn one section reinforcing bar, with zinc-plated grounding screw rod 4 and reserved steel bar welding, fixes terminal board and pre-pipe laying position (as shown in Figure 5) simultaneously when building a wall.
The overlap joint multiple should meet the solder technology requirement, simultaneously according to pre-buried concealed installation box and the pre-pipe laying (being connected to this earth terminal box knock down hole) that need do various device and pipeline in the toilet that equipotential connects well of designing requirement, local equipotential bonding comprises metal tube in the toilet, drainage pipe, metal bathtub, metal heating pipe and this one storey building bar-mat reinforcement (as shown in Figure 6).
Need to prove: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite that does not change the utility model principle, this belongs to the protection range of invention equally.
