Abstract

The utility model relates to an equipotential connection constructional element for the equipotential connection of buildings, which comprises a support seat 1, a terminal board 2 and a terminal 3, wherein, both ends of the terminal board 2 are respectively inserted into holes 4 on the support seat 1 and are pressed and fixed by tapping screws 6. The terminal 3 is composed of a terminal body 7, a wire pressing board 8 and a fastening bolt 9, wherein, the terminal body 7 which can be sheathed on the terminal board 2 to slide left and right is provided with internal threads 11 which are meshed with the fastening bolt 9, and the fastening bolt 9 is rotated to drive the wire pressing board 8 to move up and down so as to press a conductor on the terminal board 2. With the advantages of simple structure, convenient installation and high safety, the utility model is good for specialized production.

Description

The equipotential bonding member

The utility model relates to a kind of equipotential bonding member, in the architectural electricity field, is used for the total equipotential bonding of building, local equipotential bonding and auxiliary equipotential bonding.

Equipotential bonding can reduce blast and the fire that touch voltage, anti-indirect contact electric shock and earth fault cause, for a kind of especially effective safety measure of the protection of lightning protection and electronic message unit, write into international electrical engineering standard " building electric device " already and (IEC364) also write into People's Republic of China's standard " building electric device one protection against electric shock " (GB/T; 14821.1--93) and design specification as " low-voltage distribution design specification " (GB50054-95) " Code for design of lightning protection of buildings " (GB50057-94) " Code for design of dwelling houses " (GB50096-1999) " civil buildings electrical design standard " (JGJ/T16-92) etc. all equipotential is linked with specific requirement, national standard atlas " equipotential bonding installation " in 1997 publication (97SD567) is that the enforcement of China's equipotential bonding has been done to instruct more specifically, but it is also described as this atlas, the enforcement of China's equipotential bonding is still at initial period at present, the amorphous products supply still of gold utensil that equipotential bonding is used and terminal board, increase some difficulties to construction and installation, also influenced connect attractive in appearance or the like, this atlas has proposed some equipotential bonding member ways, but belong to the on-the-spot guidance way, very difficult unified and standard between the engineering, be unfavorable for checking and detecting.

The purpose of this utility model be to avoid above-mentioned the deficiencies in the prior art part and provide a kind of and help specialized producing, simple in structure, easy for installation, safe and reliable, equipotential bonding member that standard is unified.

The utility model is realized in the following manner, it comprises bearing 1, terminal board 2, terminal 3, insert respectively in the hole 4 on the bearing 1 at terminal board 2 two ends, and be fixed by tapping screw 6, terminal 3 is made up of terminal bodies 7, tension disc 8, fastening bolt 9, and terminal bodies 7 can be enclosed within on the terminal board 2 and horizontally slip, and internal thread 11 is arranged on the terminal bodies 7, with fastening bolt 9 engagement, drive tension discs 8 by rotation fastening bolt 9 and move up and down conductor is pressed on the terminal board 2.

Below in conjunction with accompanying drawing the utility model is described.

Shown in Fig. 1 and 2, the equipotential bonding member comprises bearing 1, terminal board 2, terminal 3.Have adjustable fixed installation hole 5 on the bearing 1, be used for fixing in casing, the top has the tapping screw hole to be used for fixing terminal board, and there is the hole 4 of support end daughter board the centre; Terminal board 2 is square body or rectangular cylinder, and insert respectively in the hole 4 on the bearing 1 at two ends, and is fixed by tapping screw 6; Terminal 3 is made up of terminal bodies 7, tension disc 8, fastening bolt 9; Terminal bodies 7 is the U type, and both sides have groove 10, in terminal board 2 insertion grooves 10, terminal bodies 7 can be enclosed within on the terminal board 2 and horizontally slip, internal thread 11 is arranged on the terminal bodies 7,, drive tension discs 8 by rotation fastening bolt 9 and move up and down conductor is pressed on the terminal board 2 with fastening bolt 9 engagement; With reference to shown in Figure 4, a hole 12 is arranged on the tension disc 8, and around the hole, a deep gouge 13 arranged, fastening bolt 9 bottoms are less cylinders of diameter 14, insert the Kong Zhonghou on the tension disc 8, at cap 15 of fastening bolt end riveted joint, flat with tension disc 8 bottoms in the deep gouge 13 of bottom riveted joint cap 15 on tension disc 8, the less cylinder 14 of the diameter of fastening bolt 9 bottoms can freely rotate with respect to tension disc 8; Tension disc 8 bottoms have the groove line, are difficult for landing when being beneficial to connect with conductor.

With reference to shown in Figure 3, there is the knock down hole (not shown) casing top and bottom, during construction and pipeline simultaneously pre-buried, bearing 1 is fixed on the box bottom two ends, terminal board 2 two ends are fixed on the bearing 1, make up the terminal 3 of different size on the terminal board 2, be used for the conductor of crimping different size, can indicate " equipotential bonding terminal box " and brand name on the case lid.

With reference to shown in Figure 5, terminal TE-1, TE-5 are used for the band steel or the copper strips of crimping 40 * 4; Terminal TE-2, TE-6 are used for the band steel or the copper strips of crimping 25 * 4; Terminal TE-3, TE-7 are used for crimping 16～95mm ²Lead; Terminal TE-4, TE-8 are used for crimping 2.5～16mm ²Lead.

The utility model is simple in structure, easy for installation, safe and reliable, help specialized production, filled up and implemented the big blank of equipotential bonding.
