Description

Low voltage busbar connector set

The present invention relates to a low voltage busbar connector set.

The busbars for power transmission are usually installed on the ceiling of each floor of the building and act to connect the power transmission between the floors.

The chip-shaped bus bar has a lower resistance and can transmit a large current without causing overheating, so that the bus bar can effectively conduct power to the relevant switchboard or distribution box of each floor.

However, while the sheet-shaped bus bar is transporting a large current, its structure limitation cannot necessarily make a bus bar with a long distance. Therefore, the connection between the bus bar and the bus bar needs to be connected to the joint to achieve the purpose of power transmission.

Old joints are usually punched at the joints of the busbars, and then passed through insulated bolts to securely lock the busbar joints, but the joints at the busbars are combined with the openings, which reduces the conductor contact area and increases the wiring. Connecting resistors, this phenomenon is more pronounced when using smaller conductor sizes.

There are also known techniques for punching holes at the junction of the busbars, but the copper plates and the insulating plates of the joints of the joints need to be assembled into the joint group one by one during the construction on site, and cannot be assembled first in the factory.

In view of the above needs, how to provide a low-voltage bus bar connector set which is convenient to install, easy to maintain, and has sufficient contact area has become an object of the present invention to be improved.

The purpose of the present invention is to provide a low-voltage busbar joint set capable of connecting a bus bar and a bus bar, comprising: two sets of outer plates (1); and a plurality of insulating plates (2) disposed between the two outer plates (1) Between the insulating plate (2) and the insulating plate (2), a connecting copper plate (3) capable of conducting power of the bus bar is provided; Passing through the outer plate (1), fixing the outer plate (1) to the fixed screw (4) at the junction of the two sets of busbar bodies (20); several nuts that are locked with the respective locking screws (5); characterized in that: the outer panel is provided with at least four sets of fixing holes (11) which do not affect the fixed screw fastening; the center of the outer plate (1), the center of the insulating plate (2) and the connecting copper plate ( 3) centrally, respectively provided with a perforation (6); an insulating rod (7) passing through the center of the outer panel (1), the center of the insulating plate (2) and the perforation (6) at the center of the connecting copper plate (3) .

More preferably, the outer panel (1) is an aluminum alloy outer panel.

More preferably, between the insulating plate (2) and the insulating plate (2), there are two connecting copper plates (3).

More preferably, a spacer ring (8) is provided between the two connecting copper plates (3) to maintain a spacing to facilitate the insertion of the busbar body (20).

More preferably, the fixed screw passes through the two outer plates (1), and the bus bar joint is clamped to the two bus bar bodies (20) by using nuts (5).

More preferably, the fixed screw (4) is disposed between the two outer plates (1) and is respectively sleeved on the fixed screw (4), and the fixed screw (4) cannot be fixed. Conductive insulation tube (9).

Compared with the prior art, the effects of the present invention are as follows:

The first point: Compared with the joint set made by the old technology, the new type does not need to open holes in the bus bar conductor when the bus bar is connected by the joint set, so that there is more contact area and better conduction. efficacy.

The second point: when the busbar is connected by the joint group, a metal material press plate is placed on the outermost side. The metal plate is integrally formed and has a reinforcing structure. The structural strength is better when assembling and joining, and the integral shape is formed. The factors that make the contact surface more uniform, and a positioning hole in it, ensure that each joint set is installed in the most appropriate position. When one of the screws is not locked during installation, due to the structural design, the other three screws can share the force of the screw, so as not to cause immediate danger.

The following is a detailed description of the embodiment shown in the drawings. As shown in FIG. 1 to FIG. 5, the figure discloses a low-voltage bus bar connector group capable of connecting a bus bar and a bus bar, which includes: two groups. An outer plate (1); an insulating plate (2) disposed between the two outer plates (1); and an insulating plate (2) and the insulating plate (2) are provided for electrically connecting the bus bar a copper plate (3); a plurality of fixed screws (4) passing through the outer plate (1) for fixing the outer plate (1) at the junction of the two sets of busbar bodies (20); A locking screw-locked nut (5); characterized in that: the outer plate is provided with at least four sets of fixing holes (11) which do not affect the fixing of the fixed-pile screws; the center of the outer plate (1), the insulating plate (2) The center and the center of the connecting copper plate (3) are respectively provided with a through hole (6); a through hole in the center of the outer plate (1), the center of the insulating plate (2) and the center of the connecting copper plate (3) (6) Insulation rod (7).

Among them, the whole group of low-voltage busbar joints is fixed by perforation, which can effectively increase the contact area of the copper plates and reduce the contact area of the busbars, which can make the new type have better conductivity.

In the above, the outer panel (1) is an aluminum alloy outer panel.

Among them, the aluminum alloy outer plate is integrally formed and has a reinforcing structure, and the structural strength is more excellent in assembly and joint, and the contact surface is more uniform in force due to the integral forming factor, and a positioning hole therein ensures Each connector set is mounted in the most appropriate position.
